Referring initially to the drawings, FIGS. 1-3 illustrate the removable tray device 100 that offers a simple and easy way to eat or drink when sitting outside. The removable tray device 100 comprises a tray component 102 secured to a folding chair 106 via a pinned hinge 104 that allows the tray component 102 to rotate vertically (i.e., flip 180 degrees) and a swivel component 108 that allows the tray component 102 to swivel horizontally (as shown in FIGS. 4A-C).
The tray component 102 comprises a top surface 110, a bottom surface 112, a front edge 114, a back edge 116, and opposing sides 118. Typically, the tray component 102 is rectangular in shape but can be any suitable shape as is known in the art without affecting the overall concept of the invention, such as oval, circular, square, etc., as long as the tray component 102 can support food, beverages, and/or other items. The tray component 102 would generally be constructed of UV stabilized and food grade plastics, such as polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), etc., or composite polymers, though any other suitable material may be used to manufacture the tray component 102 as is known in the art without affecting the overall concept of the invention.
The tray component 102 can also comprise a variety of colors and designs to suit user and manufacturing preference. While the shape and size of the tray component 102 may vary greatly depending on the wants and needs of a user, the tray component 102 is approximately between 13 and 14 inches in depth as measured from a front edge 114 to a back edge 116, and approximately between 19 and 22 inches wide as measured from opposing sides 118, and approximately between 3⁄4 and 1 inch thick as measured from a top surface 110 to a bottom surface 112.
Additionally, the tray component 102 is secured to a folding chair 106. The folding chair 106 can be any typical folding chair as is known in the art, or any other suitable chair, bench, etc. The folding chair 106 comprises a pair of front legs (right leg 122 and left leg 121) and a pair of back legs (right leg 125 and left leg 124), a seat 126, a back rest 128, a pair of arms (right arm 130 and left arm 131), and supports 132, and other suitable parts of a chair. The folding chair 106 typically comprises coated aluminum tubing for legs 121, 122, 124, and 125 and/or arms 130 and 131 and/or supports 132, or other suitable materials as is known in the art. The seat 126 and back rest 128 can be made from a durable, weatherproof material, such as canvas, or any other suitable material as is known in the art without affecting the overall concept of the invention.
The removable tray device 100 further comprises a pinned hinge 104 and a swivel component 108 secured to the left front leg 121 of the folding chair 106 for removably securing the tray component 102 to the front leg 121 and allowing it to move, however any other suitable mechanism can be used in place of the pinned hinge 104 or swivel component 108 as is known in the art, as long as the mechanism secures the tray component 102 to the front leg 121 and allows it to move.
The pinned hinge 104 and swivel component 108 can be secured to either front leg 121 or 122 of the folding chair 106, depending on the needs and wants of a user. The tray component 102 is then secured to whichever leg 121 and 122 of the folding chair 106 comprises the pinned hinge 104 and swivel component 108. Therefore, a right-handed user can secure the tray component 102 to the left front leg 121 of the folding chair 106 and a left-handed user can secure the tray component 102 to the right front leg 122 of the folding chair 106.
Further, the tray component 102 comprises support arms 103 (as shown in FIG. 2) and/or a support leg 105 (as shown in FIG. 4A) that is secured to the bottom 112 or sides 118 of the tray component 102 and that fold up and store under the tray component 102 when not in use. The support arms 103 and/or support leg 105 can be secured to the tray component 102 via any suitable securing means as is known in the art, such as gluing, welding, fasteners, etc. During use, the support arms 103 are folded down and secured to the legs 121, 122, 124, 125, or supports 132 of the chair 106. Specifically, the support arms 103 fit over and are secured to a raised bolt 101 or other securing device as is known in the art on the legs 121, 122, 124, 125, or supports 132 of the chair 106. The support leg 105 is typically secured to one of the sides 118 of the tray component 102 and telescopes into a compacted position during storage and then telescopes out into an extended position during use. Specifically, the support leg 105 rests on the floor when extended for use (as shown in FIG. 4A) to support the tray component 102.
Additionally, the tray device 100 comprises a pinned hinge 104 securing the tray component 102 to the left front leg 121. The pinned hinge 104 allows the tray component 102 to rotate vertically (flips 180 degrees) out in front of the folding chair 106 (as shown in FIG. 4B), or rotate downward into a storage position (as shown in FIG. 3). Then, the swivel component 108 allows the tray component 102 to swivel horizontally to a front of the folding chair 106 (as shown in FIG. 4C). The swivel component 108 is typically a swivel joint which affixes the tray component 102 to the left front leg 121 and allows the tray component 102 to swivel horizontally about the left front leg 121. However, any other suitable swivel component 108 can be used as is known in the art, as long as the swivel component 108 secures to the tray component 102 and allows it to swivel horizontally.
The pinned hinge 104 is a typical lock and release pinned hinge. The pinned hinge 104 comprises a pin 500 that secures to a snap ring 502 which secures the pin 500 within the swivel joint housing 108. The pin 500 comprises a first end 504 and a second end 506 held together by a hinge pin 508. A locking collar 510 then secures to the pin 500 and locks it (i.e., the collar 510 covers the hinge joint created by the hinge pin 508), or unlocks it (i.e., the collar 510 does not cover the hinge joint created by the hinge pin 508). A snap ring 514 holds a spring 512 onto the locking collar 510 to allow the collar 510 to move up and down to cover or uncover the hinge joint. The locking collar 510 is then secured to the tray component 102 via a bracket or other such securing mechanism. Thus, when the locking collar 510 is pushed in, it allows the tray component 102 to rotate down as the collar 510 is not covering the hinge joint, which allows the hinge to bend at the joint. When the locking collar 510 is released and the spring 512 pushes against the collar 510, the collar 510 moves over the hinge joint, restricting hinge movement and locking the tray component 102 so it cannot rotate up or down.
In a further preferred embodiment, the tray component 102 comprises a catch or lock bracket 600 on a leg 121, 122, 124, or 125 of the chair 106 which corresponds with a mating lock pin 602 secured to a back edge 116 of the tray component 102. Specifically, the lock pin 602 of the tray component 102 mates to and is secured within (i.e., always within intimate contact with) the catch or lock bracket 600 to further secure the tray component 102 to the folding chair 106 when the tray component 102 is in front of the folding chair 106 or is to the side of the folding chair 106. The chair 106 can comprise any suitable number of catch or lock brackets 600 on any one of the legs 121, 122, 124, or 125 depending on the wants and needs of a user. Furthermore, the tray component 102 comprises a cut-out or continuous opening, or a shallow indentation on the top surface 110 of the tray component 102. The continuous opening acts as a drink holder 120 for retaining a beverage or other item. The tray component 102 can comprise any suitable number of drink holders 120 depending on the wants and needs of a user.
FIGS. 4A-4B illustrate the removable tray device 100 rotating and swiveling. As stated supra, the tray device 100 comprises a pinned hinge 104 secured to the tray component 102 for allowing the tray component 102 to rotate vertically (approximately 180 degrees) out in front of the folding chair 106, or rotate down into a storage position. The tray device 100 further comprises a swivel component 108 secured to the tray component 102 for allowing the tray component 102 to swivel horizontally to the front of the folding chair 106. The swivel component 108 is typically a swivel joint which affixes the tray component 102 to the left front leg 121 and allows the tray component 102 to swivel horizontally about the left front leg 121. However, any other suitable swivel component 108 can be used as is known in the art, as long as the swivel component 108 secures to the tray component 102 and allows it to swivel horizontally.
As stated supra, the pinned hinge 104 is a typical lock and release pinned hinge. The pinned hinge 104 comprises a pin 500 secured within the swivel joint housing 108 (swivel component) via a snap ring 502. The pin 500 comprises a first end 504 and a second end 506 held together by a hinge pin 508 to create a hinge joint. A locking collar 510 then secures to the pin 500 and locks it (i.e., the collar 510 covers the hinge joint), or unlocks it (i.e., the collar 510 does not cover the hinge joint). The locking collar 510 is retained on the hinge joint via a snap ring 514 and a spring 512 which allows the collar 510 to move up and down to cover or uncover the hinge joint. The locking collar 510 is then secured to the tray component 102 via a bracket or other such securing mechanism. Accordingly, when the locking collar 510 is pushed in, the hinge is allowed to bend at the joint which allows the tray component 102 to rotate down (or vertically up) as the collar 510 is not covering the hinge joint. When the locking collar 510 is released and the spring 512 pushes against the collar 510, the collar 510 moves over the hinge joint, restricting hinge movement and locking the tray component 102 so it cannot rotate up or down.
FIG. 5 illustrates the removable tray device 100 in use. As stated supra, the removable tray device 100 comprises a tray component 102 secured to a folding chair 106 via a pinned hinge 104 that allows the tray component 102 to rotate vertically (i.e., flip 180 degrees) and a swivel component 108 that allows the tray component 102 to swivel horizontally. The tray component 102 further comprises a catch or lock bracket 600 on a leg 122 and 124 of the chair 106 which corresponds with a mating lock pin 602 secured to a back edge 116 of the tray component 102. Specifically, the locking pin 602 of the tray component 102 mates to and is secured within the catch or lock bracket 600 to further secure the tray component 102 to the folding chair 106 when the tray component 102 is in front of the folding chair 106 or is to the side of the folding chair 106. Furthermore, the tray component 102 comprises a cut-out or continuous opening that acts as a drink holder.
In operation, a user 600 would choose the size and/or color of the removable tray device 100 that meets the user's needs and/or wants. The user 600 would then attach the removable tray device 100 to a predetermined folding chair 106 via attaching the tray component 102 to the pinned hinge 104 and swivel component 108 positioned on the front leg 121 of the folding chair 106. The user 600 can then sit in the folding chair 106 and can vertically rotate (approximately 180 degrees) the tray component 102 out in front of the folding chair 106, and can horizontally swivel the tray component 102 in front of the chair 106 for use. The user 600 can then telescopically extend the support leg 105 from the side 118 of the tray component 102 to rest on the floor for additional support. Once the user 600 is done using the removable tray device 100, the user 600 can collapse the support leg 105 and reverse the direction and horizontally swivel the tray component 102 back out in front of the chair 106, then vertically rotate (i.e., flip up 180 degrees) the tray component 102 beside the chair 106, and then rotate down the tray component 102 in a storage position (as shown in FIG. 3). Thus, the removable tray device 100 provides a flat tray surface for eating, drinking, or other activities when sitting outside, and rotates down against the side of the chair 106 when not in use for convenient storage.
