Description
Background of the Invention
This invention relates in general to a multi-purpose assembly, and more particularly, to a collapsible, multi-purpose assembly adapted for use with a flexible bag which is constructed to be arranged from a compact folded position into a portable chair and container.
Today, an increasing interest is being created in outdoor activities which are planned for one's personal enjoyment and relaxation. These activities often take the form of picnics and outings to the beach where seating is generally not available. This requires the use of portable seating devices such as foldable chairs and lounges. On such occasions, it may also be necessary to transport various items, such as coolers, blankets, radios, umbrellas and the like from one's automobile to the desired beach or picnic area. This further requires the use of a separate container for carrying these items, in addition to the portable seating device. The carrying of both the container and the portable seating device is generally both inconvenient and awkward.
In accordance with the prior art, there have been constructed a variety of combined seating and container devices for use on picnics and outings to the beach. These combined devices include a container for holding the above-mentioned items to be carried from one's automobile to the desired beach or picnic area. Upon arrival at the desired area, these items are removed from the container and the combined device can be arranged into the form of a chair or lounge. Typical of one prior art construction is U.S. Pat. No. 2,840,142 which discloses a foldable cart that can be transformed from a container into a reclining chair and bed. However, it has been found that these prior art devices are generally difficult and awkward to convert from one form to the other. Also, these prior art devices are generally of complex construction which makes them expensive to fabricate.
Accordingly, there is a need for a collapsible, multi-purpose assembly which can be easily arranged into a portable chair and container by the simple manipulation of the assembly and which is inexpensive to fabricate.
Summary of the Invention
It is broadly an object of the present invention to provide a combination portable chair and container which overcomes or avoids one or more of the foregoing disadvantages from the use of the prior art combined devices. Specifically, it is within the contemplation of the present invention to provide a collapsible, multi-purpose assembly which can be formed from a compact position into the shape of a chair and container by the simple rotational movement of a portion of the assembly.
A further object of the present invention is to provide a collapsible, multi-purpose assembly which can be transported over loose terrain, such as sand and the like, with a minimum effort, particularly when arranged into a container and having a plurality of items stored therein.
A still further object of the present invention is to provide a collapsible, multi-purpose assembly which is light in weight, which is foldable to the approximate size of a conventional beach chair or lounge, and which is inexpensive to fabricate.
Yet still a further object of the present invention is to provide a collapsible, multi-purpose assembly which can be arranged from a portable chair and container into a compact folded position in a relatively simple and uncomplicated manner.
In accordance with one embodiment of the present invention, there is provided a collapsible, multi-purpose assembly. The assembly includes a base and a pair of sidewall members each having first and second ends. The first ends of the sidewall members are pivotally connected to opposite sides of the base. A pair of securing means are connected to the second ends of the sidewall members between common sides thereof. The securing means secure the sidewall members in a first position and permit the sidewall members to be arranged into a second and third position. The assembly forms a container when arranged in the first position, a chair when arranged in the second position and a collapsed assembly when arranged in the third position.
Further in accordance with the above embodiment, the collapsible, multi-purpose assembly includes rotating means adjacent to the base for moving the assembly over a desired terrain. The rotating means includes a plurality of longitudinally extending ribs arranged radially about the longitudinal axis of the rotating means.
Still further in accordance with the above embodiment, the collapsible, multi-purpose assembly is adapted for use with a flexible bag which is secured to the assembly, wherein the bag forms the sidewall portions of the container and the back and bottom portions of the chair.

Detailed Description
Referring specifically to the drawings, there is shown in FIG. 1, a collapsible, multi-purpose assembly constructed according to the present invention from tubular members and generally designated by reference numeral 100. The assembly 100 is constructed to include a base 102 having a pair of side supporting members 104, 106 and a platform 108. The side supporting members 104, 106 are provided with upwardly curved distal ends 110, 112. A pair of U-shaped sidewall members 114, 116 are formed of side arms 118, 120, respectively, and cross-members 122, 124 connected across one end of the side arms. As best shown in FIG. 7, side arms 120 are formed at their other end into a U-shaped hook 126 with a notch 128 and side arms 118 are formed at their other end into a straight end segment 130.
The assembly 100 further includes a plurality of cross-shafts 132, 134, 136, 138, a pair of telescoping tube assemblies 140 and a roller assembly 142. As shown in FIG. 2, telescoping tube assemblies 140 include tubular members 144, 146 of different diameters. The internal diameter of tubular member 144 is slightly greater than the outside diameter of tubular member 146 such that tubular members 144, 146 are held in telescoping engagement with each other. A spring button lock 148 is arranged within the tubular members 144, 146 to engage an aligned opening 150 provided in the tubular members.
As shown in FIG. 8, roller assembly 142 includes a ribbed roller section 152 having a plurality of longitudinally extending ribs 154 positioned radially about its longitudinal axis. At either end of ribbed roller section 152 are end caps 156, 158 having a stepped shoulder 160 for engagement with the open end of the ribbed roller section. The outside diameter of end caps 156, 158 are slightly greater than the outside diameter of ribbed roller section 152. End caps 156,158 include a centrally located hole 162 through which the ends of an axle 164 extend.
The operative arrangement of the above-mentioned components of the collapsible, multi-purpose assembly 100 will now be described generally with reference to FIG. 1. Side supporting members 104, 106 are secured to platform 108 using rivets, screws and the like such that distal ends 110, 112 are arranged in an upward position. Sidewall member 114 is pivotally connected at one end of its side arms 118 to distal ends 110, 112 via cross-shaft 136, as further shown in FIG. 3. Cross-shaft 136 is prevented from sliding out from distal end 110 by the use of a push on, self-locking retaining button 166. In a similar manner, sidewall member 116 is pivotally connected to distal ends 110, 112 via cross-shaft 132.
Cross-shaft 134 is secured between side supporting members 104, 106 for engagement with notch 128 provided at the end of U-shaped hooks 126 to restrict the extent of pivotal movement of side supporting member 116 in a counterclockwise direction. In a similar arrangement, cross-shaft 138 is secured between side supporting members 104, 106 to restrict the extent of pivotal movement of sidewall member 114 in a clockwise direction by engagement with a portion of straight end segments 130 of the side arms 118.
Telescoping tube assemblies 140 are pivotally connected to the upper ends of sidewall members 114, 116 between common side arms 118, 120. As shown in FIG. 4, tubular member 144 is pivotally connected to side arm 118 by pin 168 passing through both members and secured therein by a push on, self-locking retaining button 166. In a similar manner, tubular member 146 is pivotally connected to the upper end of side arm 120.
The roller assembly 142 is rotationally secured between straight end segments 130 of the side arms 118 by a push on, self-locking retaining button secured to either end of axle 164. The ends of ribbed roller section 152 are pressed onto the stepped shoulder 160 of end caps 156, 158 to permit the rotation of the roller section about axle 164.
The collapsible, multi-purpose assembly 100 is adapted for use with a flexible web or bag 170. Bag 170 is constructed from a plyable fabric and is secured to assembly 100 by eight constraining flaps 172. The top four constraining flaps 172 loop over cross-members 122, 124. Snaps 174 are provided on constraining flaps 172 for closing the flaps back on themselves. The lower four constraining flaps 172 overlay cross-shafts 132, 136 and are similarly provided with snaps 174 for closing the flaps back on themselves. The top perimeter of bag 170 has sewn into the hem an elastic strip. The elastic strip is designed to facilitate a neat appearance when the assembly 100 is in a folded position.
There has thus far been described according to the present invention, a collapsible, multi-purpose assembly for use as a portable chair and container. The assembly 100, when in its folded position, is of the approximate size and weight of a standard folding lounge or beach chair which can be suitably carried in the trunk of an automobile. Upon arrival at the beach or picnic area, the similarity with a folding lounge or beach chair ends. The assembly 100 can be opened in two quick motions and every item that previously was toted by hand is transferred into the assembly, such as coolers, blankets, radios, umbrellas and the like. At the beach or picnic area, the assembly 100 can be used to store unused items and to keep them out of sight and out of the sand contaminated environment. Once at the desired area, the items can be removed from the container, and the assembly 100 can be transformed into a comfortable portable chair as shown in FIG. 6.
The operation of the collapsible, multi-purpose assembly 100 in transformation from a compact folded position as shown in FIG. 7 to either a portable chair as shown in FIG. 6 or a container as shown in FIG. 5 will now be described with reference to these FIGS. Specifically with reference to FIG. 7, the assembly 100 is shown in its collapsed or folded position. In the folded position, sidewall member 114 overlies platform 108 by being pivoted about cross-shaft 136 in a counterclockwise direction. In a like manner, sidewall member 116 overlies platform 108 by being pivoted about cross-shaft 132 in a clockwise direction. Telescoping tube assemblies 140 permit sidewall members 114, 116 to be folded on top of each other by being pivotally attached to side arms 118, 120 and their collapsing from their longitudinally extended position. The assembly 100 is now arranged in a compact folded form similar to a lounge or beach chair and can be easily transported by grabbing the U-shaped hooks 126 on sidewall member 116. The assembly 100 in its collapsed position occupies a minimum of space.
Upon arrival at the picnic or beach area, the assembly 100 is removed in its collapsed or folded position as shown in FIG. 7. The assembly 100 may be transported to the desired area and subsequently arranged into a comfortable chair as shown in FIG. 6, or can be arranged into a container as shown in FIG. 5. The assembly 100 is arranged into a chair from a folded position by grabbing cross-member 124 and rotating sidewall member 116 in a counterclockwise direction about cross-shaft 132 until notch 128 engages cross-shaft 134. Sidewall member 116 is now arranged in a generally upright position with sidewall member 114 remaining overlying base 102. Sidewall member 116 and bag 170 form the back portion 178 of the chair and sidewall member 114 in conjunction with bag 170 and platform 108 form the bottom portion 180 of the chair. As sidewall member 116 is pivoted in a counterclockwise direction, the telescoping tube assemblies 140 pivot about pin 168 and is longitudinally extended from its collapsed position as shown in FIG. 7.
The assembly 100 in the form of the chair as shown in FIG. 6 can be easily converted into the form of a container as shown in FIG. 5. The assembly 100 is transformed into a container by grasping cross-member 122 and pivoting sidewall member 114 about cross-shaft 136 in a clockwise direction until straight end segments 130 of side arms 118 engage cross-shaft 138. As sidewall member 114 is pivoted, telescoping tube assemblies 140 likewise pivot about pins 168 and longitudinally extended from their position as shown in FIG. 6. As the sidewall member 114 approaches a general upright position, telescoping tube assemblies 140 are locked in position by spring button lock 148 engaging opening 150 as shown in FIG. 2. Telescoping tube assemblies 140 secure sidewall members 114, 116 in a spaced apart relationship such that the sidewall members, telescoping tube assemblies and bag 176 form the side wall portions 182 of the container as shown in FIG. 5.
To fold the assembly 100 from the container as shown in FIG. 5, spring lock button 148 is depressed on telescoping tube assemblies 140 while urging sidewall members 114, 116 pivotally towards each other. As sidewall members 114, 116 pivot towards each other, telescoping tube assemblies 140 pivot about pins 168 and longitudinally collapse allowing the sidewall members to be folded respectively over base 102 to form either the chair as shown in FIG. 6 or a collapsed assembly as shown in FIG. 7.
In accordance with an additional feature of the present invention, a removable snap on table top 184 is provided. The table top 184 includes a retaining lip 186 to define a table surface 188. The table top 184 is secured to the assembly 100 when in the form of a container as shown in FIG. 5. Lip 186 of table top 184 is constructed to include semi-circular lugs 190 located at its four corners. Lugs 190 are constructed and arranged to engage tubular members 144, 146 of the telescoping tube assemblies 140.
In accordance with another feature of the present invention, assembly 100 is provided with a roller assembly 142 having a ribbed roller section 152 to allow the assembly, when in the form of a container, to be rolled over loose terrain such as sand and the like with a minimum of effort. Roller assembly 142 is positioned adjacent base 102 such that the total weight of the assembly 100 and its contents are distributed over the total area of the ribbed roller section 152 in contact with the sand. This total load weight distribution reduces the depth that ribbed roller section 152 settles into the sand thereby minimizing the effort required to roll assembly 100. The space between ribs 154 accommodates the sand which in turn tends to hold the ribs in place. Roller assembly 142 rotates about axle 164 as the assembly 100 is pulled across the sand. Ribs 154 provide roller assembly 142 with a uniform rolling action which avoids skids and sand from piling up in front of the roller which would inhibit its uniform rolling action.
As previously described, roller assembly 142 is provided with end caps 156, 158 having a diameter greater than the radial extent of ribs 154 and a hole 162 centrally located therein. As a result of end caps 156, 158 having a slightly larger diameter than ribs 154, the ends caps provide a smooth and vibration free rolling action for the assembly 100 on hard surfaces by avoiding contact with ribs 154. In addition, caps 156, 158 provide an axle bearing for ribbed roller section 152.
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and application of the present invention. It is to be understood that numerous modifications may be made in the illustrative embodiments and other arrangements may be devised without departing from the scope of the present invention as defined by the appended claims.
