Description
Field of Invention
The present invention relates to toy glider airplanes, and particularly relates to a toy glider airplane made from a container and a method for making the same from a straw and a rigid cellular polystyrene container (a styrofoam container) such as a hamburger container commonly found in fast-food restaurants.
Background of Invention
Toy glider airplanes have been constructed in accordance with many different designs from numerous materials including balsa wood, paper, styrofoam and plastic. It is known that toy glider airplanes may be constructed from one or more sheets of styrofoam (rigid, lightweight cellular polystyrene). However, conventional toy airplanes are generally complicated in design and construction so that such airplanes are difficult or cumbersome to construct. Particularly, children find airplanes of known designs difficult to make.
Furthermore, known airplane designs are not adapted to be constructed from styrofoam containers such as hamburger containers commonly used in fast food restaurants. Known methods of constructing toy airplanes do not include a method for constructing a toy airplane from a container and a straw. And, known containers such as styrofoam hamburger containers do not include tear lines for facilitating the construction of a toy airplane from the container.
Summary of the Invention
In the present invention, a toy airplane is constructed from a container, and in a particular embodiment, a toy airplane is constructed from a styrofoam hamburger container and a straw. This particular toy airplane uses the V-shape and the curved contours of the hamburger container to form a stable and efficient gliding airplane. Although the airplane of the present invention is a stable and efficient glider, it is simple to construct so that even children will have little or no difficulty in constructing it.
In accordance with another aspect of the present invention, a method is disclosed for constructing an airplane from a straw and a container in which tear lines are formed on the container in the shape of wing structures for use in constructing the toy airplane. The container is weakened along the tear lines, and the wings are removed from the container by tearing action along the tear lines. The wings are then mounted on the straw which functions as a fuselage for the toy airplane.
In accordance with a particular aspect of the invention, a toy glider airplane for being constructed at least partially from a container formed of generally planar material includes a drinking straw having a forward and a rearward end. A plurality of wing structures are constructed from the generally planar material of the container, and at least one of the wing structures is mounted on a forward end of the straw to form a forward main wing of the toy airplane for providing lift during flight. At least one of the wing structures is mounted on the rearward end of the straw for controlling the orientation of the toy airplane during flight.
In accordance with another aspect of the present invention, a toy glider airplane for being constructed from a container formed of generally planar material includes a wing constructed of the generally planar material of the container and has a V-shaped midregion with two wing portions extending outwardly from the outer edges of the V-shaped midregion. The center of the V-shaped midregion of the wing is attached to the forward end of a substantially rigid fuselage. A planar brace member is attached to the wing and extends across the top of the V-shaped midregion to form a triangular load bearing wing structure. The brace member is operable to reinforce the V-shaped midregion of the wing to prevent deformation thereof under loading on the wing portions before and during flight of the airplane. Flight control wings constructed of the generally planar material are mounted adjacent to the rearward end of the fuselage for controlling orientation of the airplane during flight.
In accordance with a method of the present invention for constructing a toy airplane from a fuselage and a container made of generally planar material, a tear line is formed in the container with the tear line outlining the shape of at least one wing structure on the container. The container is torn along the tear line and at least one wing structure is removed from the container. This wing structure is attached to the fuselage to construct a toy airplane.
In accordance with another aspect of the present invention, a container for containing food and the like and for use in contructing a toy airplane includes at least one compartment constructed of a generally planar material. Structure is provided for closing the compartment to isolate and contain food and the like within the compartment. A tear line is formed in the container in the shape of at least one wing, and the compartment is weakened along the tear line to facilitate tearing the wing from the compartment.
In accordance with another aspect of the present invention, a container has an upper compartment constructed of generally planar material with an open bottom, a closed flat top, and four generally upright sides inclined inwardly from the open botton to the flat top so that the upper compartment has a truncated quadrangular pyramid shape. The upper compartment has rounded corners at the intersections of the upright sides and the top thereof, and has rounded edges at the intersections of the generally upright sides thereof. The container further has a lower compartment constructed of generally planar material with an open top, a closed flat bottom and four generally upright sides inclined upwardly from the open top to the closed flat bottom so that the lower compartment has a truncated quadrangular pyramid shape. The open top of the lower compartment is constructed to mate with the open bottom of the upper compartment to form a closed container. The lower compartment has rounded corners at the intersections of the sides and the bottom thereof and has rounded edges at the intersections of the upright sides thereof. The container further has a living hinge formed between the lower edge of an upright side of the upper compartment and the upper edge of an upright side of the lower compartment so that the compartments are rotatable between a closed position in which the upper compartment is disposed above the lower compartment to form a closed container and an open position in which the upper and lower compartments are disposed in a side-by-side relationship.
In accordance with an improvement of the container, a wing tear line extends along the upper and lower compartments outlining a wing for a toy airplane on the container. The wing is positioned on the container with the living hinge disposed in the center of the wing in an orientation perpendicular to the wing span, and the living hinge divides the wing into two wing portions so that the wing may be formed from the container by tearing the container along the tear line and rotating the wing about the living hinge to an extended position. In the extended position, the wing portions on either side of the living hinge extend in generally opposing directions with a V-shaped midregion being formed in the wing by that portion of the wing taken from the sides of the compartments and the living hinge. The wing includes a leading edge that extends across the flat bottom of the lower compartment, extends over a rounded corner at the intersection of the bottom and two sides of the lower compartment, extends along a rounded edge formed at the intersection of two sides of the lower compartment, extends across the living hinge, extends along a rounded edge formed at an intersection of two sides of the upper compartment, extends across a rounded corner formed at the intersection of two sides and the top of the upper compartment, and extends across the flat top of the upper compartment so that the leading edge of the wing is curled downwardly along and adjacent to the V-shaped midregion in the wing to form a gull-wing shape.
In accordance with another aspect of the present invention, the wing is positioned on the above described container with the leading edge of the wing disposed along a curled edge of the container between the top and an upright side and between the bottom and an upright side. In this construction, the wing will have a downwardly curled leading edge to give the wing aerodynamic lift.

Detail Description
Referring now to the drawings in which like reference characters designate like or corresponding parts throughout the several views, there is shown in FIG. 1 a food container 10 embodying the present invention. The food container 10 includes an upper compartment 12 and a lower compartment 14 which are pivotally connected together by a living hinge 16. In FIG. 1, the container 10 is shown in an open position with compartments 12 and 14 disposed in a side-by-side relationship. The upper compartment 12 may be rotated about the living hinge 16 to a position above the lower compartment 14 to form a closed container. This latter position will hereinafter be referred to as the closed position.
The upper compartment 12 has a closed flat top 18, an open bottom 20 and four generally upright sides 22, 24, 26, and 28 that are inclined inwardly from the open bottom 20 to the flat top 18 so that the upper compartment 12 has a truncated quadrangular pyramid shape. Rounded corners 30, 32, 34, and 36 are formed at the intersection of the upright sides 22, 24, 26, and 28 and the flat top 18, and rounded edges 38, 40, 42, and 44 are formed at the intersections of the upright sides 22, 24, 26, and 28.
The lower compartment 14 is substantially similar to the upper compartment 12. However, the lower compartment 14 has an open top 46 and a flat bottom 48. The open top 46 is configured to mate with the open bottom 20 of the upper container 12 to form a closed container 10. The lower compartment 14 includes four generally upright sides 50, 52, 54, and 56 with rounded edges 66, 68, 70, and 72 being formed at the intersections of the upright sides. Rounded corners 58, 60, 62, and 64 are formed at the intersections of the upright sides 50, 52, 54, and 56 and the flat bottom 48.
To the extent described above, the container 10 is a conventional container for holding hamburgers and the like. This type of container is often used in fast food restaurants for temporarily storing food and maintaining it in a hot, moist condition.
In accordance with the invention, a wing tear line 80 extends along the upper and lower compartments 12 and 14 outlining a wing 82 for a toy airplane on the container 10. The wing 82 is positioned on the container with the living hinge 16 disposed in the center of the wing in an orientation perpendicular to the wing span. The living hinge 16 divides the wing 82 into two wing portions 84 and 86 so that the wing may be formed from the container by tearing the container along the tear line 80 and rotating the wing 82 about the living hinge 16 to the extended position as shown in FIG. 1. In the extended position, the wing portions 84 and 86 on either side of the living hinge 16 extend in generally opposing directions with a V-shaped midregion 88 being formed in the wing 82 by that portion of the wing taken from the sides 24 and 56 and the living hinge 16. The wing 82 has a leading edge 90 that extends across the flat bottom 48, extends over a rounded corner 64, extends along a rounded edge 72, extends across the living hinge 16, extends up the rounded edge 40, extends across the rounded corner 32, and extends along the flat top 18. In this construction, the leading edge 90 of the wing 82 is curled downwardly along and adjacent to the V-shaped midregion 88 to form a gull-wing shape.
A rudder tear line 92 is formed on the flat top 18 of the upper compartment 12 in the shape of a rudder 94. The rudder 94 has a somewhat truncated triangular shape with a leading edge 96 that is inclined rearwardly from the base to the top of the rudder.
An elevator tear line 98 is formed in the flat bottom 48 of the lower compartment 14 to outline an elevator wing 100 thereon. The elevator wing 100 includes an elevator slit 102 formed in the center of the elevator wing and perpendicular to the wing span thereof.
A tab tear line 104 outlines an elongate rectangular tab 106 on the side 50 of the lower compartment 14, and a brace tear line 108 outlines a generally rectangular elongate brace 110 on side 22 of the upper compartment 12. A letter "A" is imprinted on the tab 106 and a letter "B" is imprinted on the brace 110 for identification purposes.
Tab slits 112 are formed on either side of the living hinge 16 in the compartment sides 56 and 24. The tab slits are located adjacent to the living hinge 16 and are dimensioned to receive the ends of the tab 106. Brace slits 114 are also formed on either side of the living hinge 16 in the compartment sides 56 and 24. The brace slits 114 are formed near the top of the V-shaped midregion 88 of the wing 82 and are dimensioned to receive the ends of the brace 110.
The tab slit 112 is identified on the container 10 by the letter "A" and corresponds to the letter "A" shown on the tab 106. Thus, the letter "A" identifies the slits into which the tab 106 is intended to be inserted. The slits 112 have a length in excess of the width of the tab 106 so that the tab 106 may be moved forwardly and rearwardly in the slits. As will hereinafter be described in greater detail, the tab 106 is used to mount the wing 82 on a fuselage. By moving the tab 106 within the slits 112, the position of the wing 82 on a fuselage can be adjusted.
The slits 114 are identified by a letter "B" identifies the slit to which the brace 110 is intended to be inserted.
The tear lines formed in the container 10, namely the wing tear line 80, the rudder tear line 92, the elevator wing tear line 98, the tab tear line 104, and the brace tear line 108 may be formed in a number of ways. Such tear lines may be formed by perforating, by scoring, by crimping or by any other conventional method of weakening planar material along a tear line. It is important that the container 10 be weakened along the tear line to enable the various airplane components to be easily torn from the container, but it is also important that the tear lines do not interfere with the usefulness of the container 10. Thus, the tear lines should remain sufficiently strong to prevent inadvertent breakage of the container 10 along the tear lines while the container is being used as a container for food and the like.
The tear lines should be made by a process such as tearing or scoring when it is desired to use the container 10 as a liquid or vapor tight container. However, when it is not important that the container 10 retain liquids, the container may be perforated using a series of holes to form the tear lines. Perforation could also include crimping between the series of holes to further weaken the container 10 along the tear lines to facilitate removal of the airplane parts therefrom.
The slits formed in the container 10, namely slits 102, 112, and 114 may be completely formed in the container 10 when it is not necessary for the container to retain liquids. However, if it is desired that the container retain liquids and vapors, the slits may be formed by scored or crimped tear lines as previously described. In such case, the slit would be punched out or torn open during the construction of the airplane.
The toy airplane 118 as shown in FIG. 2 is constructed from a straw 120 and the components taken from the food container 10. The wing 82 is torn from the container 10 and mounted on the forward end of the straw 120 with the straw positioned within the V-shaped midregion 88 adjacent to the living hinge 16. The brace 110 is torn from the container 10 and inserted through the slits 114 to form, in conjunction with the V-shaped midregion 88 a triangular wing structure that resists deformation during loading on the wing 82.
Two aileron slits 122 are formed on each wing portion 84 and 86 to form ailerons on the trailing edges of the wing portions. The trailing edge of the wing 82 may be bent upwardly or downwardly between the aileron slits 122 to control the glide flight of the airplane 118 in the manner of conventional ailerons.
The rudder 94 is mounted on the rearward end of the straw 120, and the elevator wing 100 is mounted on the rudder 94. The top of the rudder 94 is inserted through the elevator wing slit 102, and the elevator wing 100 is forced downwardly to jam the leading and trailing edges of the rudder 94 against the forward and rearward ends of the slit 102. Thus, the resiliency of the rudder 94 and the elevator wing 100 operate one against the other to jam the elevator wing 100 firmly on the rudder 94. A screw 124 is threadedly secured in the forward end of the straw 120 and functions as a weight to improve the flight of the toy glider airplane 118. It will be understood that any type of weight secured in the forward end of the straw 120 will be sufficient to balance the airplane 118 and improve its glide flight.
Also, in FIG. 2 it will be appreciated that the leading edge of the wing 82 along and adjacent to the V-shaped midregion 88 is curled downwardly. This downward curl in combination with the V-shape creates a gull-wing resembling the wing of a seagull. Through testing, it has been determined that the gull-shaped wing 82 provides efficient and stable gliding for the airplane 118.
In FIG. 3, the toy glider airplane 118 is shown in an underside positioned within the V-shaped midregion 188 adjacent to the living hinge 16. The brace 110 is torn from the container 10 and inserted through the slits 114 to form, in conjunction with the V-shaped midregion 88 a triangular wing structure that resists deformation during loading on the wing 82.
Two aileron slits 122 are formed on each wing portion 84 and 86 to form ailerons on the trailing edges of the wing portions. The trailing edge of the wing 82 may be bent upwardly or downwardly between the aileron slits 122 to control the glide flight of the airplane 118 in the manner of conventional ailerons.
The rudder 94 is mounted on the rearward end of the straw 120, and the elevator wing 100 is mounted on the rudder 94. The top of the rudder 94 is inserted through the elevator wing slit 102, and the elevator wing 100 is forced downwardly to jam the leading and trailing edges of the rudder 94 against the forward and rearward ends of the slit 102. Thus, the resiliency of the rudder 94 and the elevator wing 100 operate one against the other to jam the elevator wing 90 firmly on the rudder 94. A screw 24 is threadedly secured in the forward end of the straw 120 and functions as a weight to improve the flight of the toy glider airplane 118. It will be understood that any type of weight secured in the forward end of the straw 120 will be sufficient to balance the airplane 118 and improve its glide flight.
Also, in FIG. 2 it will be appreciated that the leading edge of the wing 82 along and adjacent to the V-shaped midregion 88 is curled downwardly. This downward curl in combination with the V-shape creates a gull-wing to the wing of a seagull. Through testing, it has been determined that the gull-shaped wing 82 provides efficient and stable gliding for the airplane 118.
In FIG. 3, the toy glider airplane 118 is shown in an underside perspective view to further illustrate the construction of the airplane. The wing 82 is mounted on the straw 120 by first forming slits in the forward end of the straw 120. The straw is then positioned within the V-shaped midregion 88 adjacent to the living hinge 16. The slits in the forward end of the straw 120 are aligned with the tab slits 112, and the tab 106 is then inserted through both the tab slits 112 and the slits in the straw 120 to secure the wing 82 to the straw. It will be recalled that the tab slits 112 have a length exceeding the width of the tab 106 so that the position of the wing 82 may be adjusted relative to the straw 120 by moving the tab 106 within the slits 112. It will be appreciated that the wing position could be further adjusted by making the slits in the forward end of the straw 120 also greater in length than the width of the tab 106. Then, the tab 106 could be moved forwardly and rearwardly along the slits in the straw. To fix the position of the wing 82 relative to the straw 120, the straw slits and the tab slits 112 should be constructed having a length equal to the width of the tab 106.
In the preferred embodiment, the length of the slits in the forward end of the straw 120 is just slightly greater than the width of the tab 106 to provide a tight fit between the tab and the slits in the straw. To insure that the tab 106 will not be inadvertently removed from its proper position on the airplane 118, the tab 106 is dimensioned to extend approximately one-quarter of an inch beyond each tab slit 112.
FIG. 3 shows the triangular wing structure formed by the V-shaped midregion 88 and the brace 110. When wing loading occurs, the wing 82 would tend to rotate or fold about the living hinge 16. The brace 110 extending across the top of the V-shaped midregion 88 will resist deformation of the wing about the living hinge 16. Upward forces along the wing 82 such as experienced during flight will cause compression loading on the brace 110, and downward forces along the wing 82 will cause tension loading on the brace 110. In either event, deformation of the wing 82 is resisted by the brace 110. To function properly, there must be a tight fit between the brace slits 114 and the brace 110. Thus, the brace slits 114 have a width approximately equal to or slightly smaller than the thickness of the brace 110. It is necessary to force the brace 110 through the brace slits 114 so that the brace is resiliently held within the slits 114. The brace 110 is dimensioned to have a length sufficient to allow each end of the brace to extend approximately one-half inch beyond the slits 114 to insure that the brace 110 is not inadvertently removed from its proper position on the airplane 118 during use.
Referring now to the rearward end of the toy airplane 118, the mounting of the rudder 94 on the straw 120 is clearly shown in FIG. 3. A pair of slits 128 are formed in the rearward end of the straw 120 in a plane perpendicular to the wing span of the wing 82. The length of the tail slits 128 is less than the length of the base 130 of the rudder 94. The rudder 94 has a somewhat truncated triangular shape with the top of the rudder being smaller in width than the base 130 of the rudder. Thus, the top of the rudder 94 is inserted from the bottom of the straw 120 through the tail slits 128, and the rudder is forced upwardly until the leading and trailing edges of the rudder are jammed against the forward and rearward ends of the tail slits 128. In this manner, the resiliency of the styrofoam rudder 94 and the plastic straw 120 holds the rudder firmly in place within the tail slits 128.
Referring now to the forward end of the straw 120, it will be noted that a rounded rubber weight 132 is secured therein. The weight 132 is made of soft rubber and has a rounded shape to provide a soft blunt tip on the airplane 118. A projection extends from the rubber weight 132 and is resilienty secured within the straw 120 to mount the weight 132 in the straw. The weight 132 may be constructed entirely of soft rubber, or may be a rubber cap on the head of a screw such as screw 124 shown in FIG. 2. In either construction, the function of the weight 132 is to provide the necessary weight in the forward end of the airplane 118 for balance and to provide a soft tip on the airplane, thereby, preventing injury when the airplane strikes an object or a person.
Referring now to FIG. 4, there is shown a front isometric view of the airplane 118. In this view, the structure of the wing 82 including its bracing and attaching structure is clearly shown. The tab 106 extends through the straw 120 and through the tab slits 12 to secure the straw 120 to the wing 82. The brace 110 extends across the top of the V-shaped midregion 88 through the brace slits 114 to form a triangular wing structure for resisting deformation under wing loading. It will be appreciated that this structure is simple in design and easy to construct, and yet provides an efficient and stable glider airplane.
In the embodiments described with reference to FIGS. 1-4, only the midregion 88 has downwardly curved leading edges. Referring to FIG. 1, it will be appreciated that the leading edge of the wing 82 may be cut along the curved edge between the bottom 48 and the upright side 50 and along the curved edge between the top 18 and the upright side 22. In such case the entire leading edge of the wing 82 would be curved downwardly as shown in the cross sectional view of the wing 82 in FIG. 5.
In FIG. 5, the wing 82 has been cut from the container 10 as described above to have a down turned leading edge 83. The particular cut through container 10 used to form the wing 82 as shown in FIG. 5 has left a notch 85 on the underside of the wing to creat aerodynamic drag. If desired, the cut through the container may be positioned to eliminate the notch 85 and reduce overall wing drag. In the construction shown in FIG. 5, the wing 82, with or without notch 85, has aerodynamic lift by virtue of its shape.
Referring now to FIG. 6, there is shown an alternate embodiment of the present invention in which a styrofoam container 140 has a plurality of tear lines formed along the container in the shape of toy airplane structures. Specifically, the tear lines outline a main wing 142 having a pair of tab slits 144 formed therein. The tear lines also outline an elevator wing 148, a rudder 152, and a tab 146. The elevator wing includes an elevator slit 150 formed in the center of the elevator wing in an orientation perpendicular to the elevator wing span. As in the first embodiment, the elevator wing slit 150 is dimensioned for mounting the elevator wing 148 on the rudder 152 as previously described. The tab slits 144 are dimensioned to snugly receive the ends of the tab 146.
Referring now to FIG. 2, there is shown a front view of an airplane 154 that is constructed from the components shown in FIG. 6. The main wing 142 is attached to a straw 120 in a fashion as shown in FIGS. 2-4. Slits are formed in the forward end of the straw 120, and the straw is positioned in the center of the wing 142 with the straw slits positioned between the tab slits 144. The tab 146 is then inserted through the slits in the straw 120 and through the tab slits 144 to secure the wing 142 to the straw.
The rudder 152 is mounted on the rearward end of the straw 120, and the elevator wing 148 is mounted on the rudder 152 in the same manner as described in conjunction with FIG. 3 and the first embodiment of the present invention.
Referring now the FIG. 8, and alternate rear tail section 155 is shown for being constructed from a styrofoam food container. The tail section 155 includes two upright rudders 156 and 158 mounted on a generally horizontal elevator wing 160. The elevator wing 160 is inserted through tail slits 162 in the rearward end of the straw 120 to mount the elevator wing on the straw. The rudders 156 and 158 are mounted on the elevator wing 160 by inserting the ends of the elevator wing 160 through the rudder slits 164 and 166.
The airplane 154 shown in FIGS. 6 and 7, and the tial section 155 shown in FIG. 8 is intended to exemplify different embodiments of the present invention. Although particular embodiments of the present invention have been described in the foregoing Detailed Description, it will be appreciated that the invention is capable of numerous rearrangements, modifications and substitutions of parts without departing from the spirit of the invention. The embodiments shown in FIGS. 5-8 are considered modifications of the embodiment of the invention described in conjunction with FIGS. 1-4.
