Description of the Preferred Embodiment
The combination backpack and chaise of this invention is generally indicated at 10 in FIG. 1. The backpack and chaise combination is shown as being carried on the back of person 12. The combination has shoulder straps to engage over the shoulders of the person and a waist strap to engage around his waist so that the combination backpack and chaise can be comfortably carried on the person's back between the site of use and the site of storage. The backpack 14 is separable from the chaise. The frame of the chaise is generally indicated at 16 in FIGS. 3 and 4. The erected chaise, with its cover, is indicated at 18 in FIG. 2. The cover is generally indicated at 20 in that figure.
The main frame of the chaise is a rigid structure which comprises left and right side rails 22 and 24. The left and right designations are applied as seen by the user sitting in the chaise. The front end of the left and right side rails are respectively turned down to form left and right front legs 26 and 28. Similarly, the rear ends of the left and right side rails are turned down to form left and right rear legs 30 and 32. At their lower ends, the front legs are joined by crossbar 34 and the rear legs are joined by crossbar 36. As is seen in FIG. 3, the side rails, front and rear legs and crossbars can be bent of a single member. All of the members are preferably of aluminum tubing or other lightweight and strong material. This structure forms the main frame of the chaise. The main frame is strengthened by crossbars 38 and 40, respectively between the front and rear legs and left and right lower side rails 42 and 44. The lower side rails are respectively below the left and right side rails and are respectively secured to the left legs and the right legs, as seen in FIG. 3. All attachments are preferably made by welding, or the like. It is to this structure to which the movable parts of the chaise are attached.
Left and right leg support rails 46 and 48 are telescopically received in left and right telescope tubes 50 and 52. The telescope tubes are respectively secured to the facing sides of the left and right side rails 22 and 24 so that the top of the telescope tube is the same height as the top of the side rail. This places the telescope tubes closer together than the side rails. The left and right leg support rails are suitably spaced to be slidably received in the telescope tubes. The leg support rails are joined at their forward end by left and right leg support legs 54 and 56. These legs are joined at their lower ends by cross rail 58. As is seen by the dashed line position in FIG. 3 and the full line position in FIG. 4, the leg support legs can be moved close to the front legs of the main frame when the telescope is closed, and as seen in FIG. 3, can be pulled forward to an extended position. Cross bar 60 is secured to the leg support legs above cross rail 58 to provide strength to the system.
In order to further extend support, foot support loop 62 is provided. The foot support loop 62 is U-shaped and made of the same aluminum tubing. At its open end toward the back of the chair, it is pivoted on flanges 64 and 66 which are secured to the left and right leg support rails 46 and 48, where they bend downwardly to form legs 54 and 56. In order to releasibly hold the foot support loop 62 in the raised position shown in FIG. 3, stop plates 68 and 70 are mounted on pivot pins on the sides of the foot support loop 62. The stop plate 70 is shown in more detail in FIG. 4 where it is mounted on pivot pin 72. Stop plate 70 has a slot 74 therein. The slot engages upon stop pin 76 to permit upward swinging motion of the foot support loop 62 to the position shown in FIG. 3. Hook 78 in the slot engages on stop pin 76 to detachably retain the foot support loop in the raised position. Thus, two additional extensions of leg and support can be achieved beyond the main frame of the chaise, and these extensions can be telescoped and pivoted down to occupy minimum space, as seen in FIG. 4.
Backrest 80 is structural tube formed into a U-shaped configuration. The left and right arms 82 and 84 of the backrest respectively telescopically slide into backrest tubes 86 and 88. The tubes 86 and 88 are respectively pivoted on pins 90 and 92. The pins are carried on bosses respectively secured to the left and right side rails near the rear end thereof. The bosses are raised enough so that, when the backrest lies forward in its folded position, the backrest lies just above the slide rails with a slight space therebetween. The height of the backrest telescoping tubes and the shape of the telescoping portion of the backrest are such that, when the backrest is folded forward, the top of the backrest lies adjacent foot support loop 62, as seen in FIG. 4. This structure is such that the backrest can lie forward in the folded position. When raised, the upper loop of the backrest may be raised above its telescoping tubes and may be held in the raised position by any convenient detent .
The angle of the back with respect to the main frame of the chaise is controlled by back stops 94 and 96, which are respectively pivoted on the lower ends of backrest telescopic tubes 86 and 88, below their pins 90 and 92. The back stop 96 is shown in more detail in FIGS. 4 and 5, and the back stop 94 is symmetrically identical. The back stops are joined by cross bar 98 so they act together. Each of the back stops has saw teeth on the bottom thereof. Saw tooth 100 is particularly illustrated in FIG. 4. The particular purpose of the saw teeth is to retain the backrest in a selected angular position. To this end, bars 102 and 104 are mounted on top of the cross bar 40 adjacent its ends so that they are positioned directly under the back stops 94 and 96. In FIG. 5, the saw tooth 100 (specifically identified in FIG. 4) is engaged upon bar 104. The geometry is such that the back 80 is retained at a selected angle. The different saw teeth provide different rest angles of the back 80. When the backrest is in the forward, folded position shown in FIG. 4, the back stops 94 and 96 must be restrained. Restraint is accomplished by means of hooks 106 and 108 respectively mounted on legs 30 and 32. As seen in FIG. 4, when the back is in the forward position, the ends of the cross bar 98 are engaged in the hooks 106 and 108 to restrain the back stops.
Arm rests 110 and 112 are provided. Arm rest 112 is shown in more detail in FIGS. 7 and 8. Arm rest housing 114 is secured to right side rail 24 and right lower side rail 44. Housing 114 has a vertical slot therethrough. The arm rest itself has a pad 116 and post 118. The post extends downwardly through the slot 120 in the housing. Post 118 is in the form of a shallow channel, as seen in FIG. 8. As seen in FIGS. 7 and 8, the post 118 has a series of notches therein, with notches 122 and 124 being shown in FIG. 7 and notch 122 being shown in FIG. 8. The height of the arm rest is controlled by means of stop plunger 126. The stop plunger wraps around post 118, as seen in FIG. 8, and has dogs which engage in the post notches. Dog 128 is shown. Spring 130 resiliently urges the dogs into the notches. By pressing on the actuation plate 132 on the front of the stop plunger, the dogs are disengaged from the notches so that the height of the pad 116 can be adjusted. In the lowermost position, the pad 116 lies directly over side rail 124, as seen in FIG. 4, to permit the back to come down as far as possible.
The chaise cover 134 is shown in FIG. 2. It is preferably made of sturdy fabric and preferably has a pocket at its top in which is received the loop of the backrest. In arranging the chaise for use, it is erected from the configuration of FIG. 4 to the configuration of FIG. 3. The chaise cover is placed thereon by engaging its pocket over the backrest and pulling the fabric down over the main frame. On the seat portion of the main frame, the chaise cover is pulled over the side rails, is engaged under the lower side rails, and is secured to itself, as by Velcro or other detachable fastening means. This portion of the application of the chaise cover is shown in FIG. 6. A separate foot rest cover is employed for leg and foot support. It preferably has a pocket therein for receipt of the foot support loop, as seen in FIG. 2. The cover then engages around leg support rails 46 and 48 and attached to itself by convenient detachable fastening means such as Velcro. With the cover on, the foot rest may be raised or lowered and the angle of the backrest adjusted. In this way, comfort is achieved. When it is time to fold up, the cover is removed and the framework part of the chaise is moved into the folded, compact position of FIG. 4.
Backpack 14 is seen in FIGS. 1 and 9 and is shown under the assembled chaise in FIG. 2. Backpack 14 has convenient openings means, such as zipper 136, to permit access to the contents of the backpack and to permit storage in the backpack. The chaise cover may be stored therein. As previously discussed, various beach goods, such as towels, suits and suntan lotion, may be packed therein, as well as other needed or desired equipment. The backpack is attached to the folded chaise frame by means of a plurality of straps. Straps 138, 140 and 142 are shown at the bottom end of the pack in FIG. 9 to engage around the left and right rear legs and cross bar 36. Similarly, straps 144, 146, and 148 are provided to engage around the front legs 26 and 28 and front crossbar 34. As seen in FIG. 9, additional straps are provided to engage around the side rails. This secures the pack in place between the legs of the folded chaise. The configuration of the chaise is such that, when the chaise is folded, as seen in FIG. 4, there is a space between the side rails and the back telescoping tubes 86 and 88 to permit the wearer's back to fit therebetween. In this way, the back rests against the pack for a comfortable fit. Conventional straps are provided on the backpack 14 for carrying. For example, shoulder straps 150 and 152 are provided to engage over the shoulders of the person 12, and waist belt 154 is provided to engage around the waist of the person for comfortable carrying. In this way, the backpack and chaise can be comfortably carried to and from the site where it is used and may be used as an enjoyable resting device.
