- The following detailed description illustrates the invention by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use the invention, describes several embodiments, adaptations, variations, alternatives, and uses of the invention, including what is presently believed to be the best mode of carrying out the invention.
- A first embodiment is shown in
FIGS. 1-6 , attached to alawn chair 30. Thelawn chair 30 is illustratively of a common design having a frame constructed to allow a generally planar seat part and a generally planar back part to fold from a working position in which they are generally at right angles to each other to a stored position in which the seat part and the back part are generally parallel. In the illustrative embodiment, the frame is made of aluminum tubing, although frames of steel tubing and wood, for example, are also well-known. Numerous constructions of such chairs are known. - In this embodiment, the folding
chair 30 has a frame formed of a U-shapedforward leg tube 33, a U-shapedrear leg tube 39, aU-shaped seat tube 45, and aU-shaped back tube 47. The free ends of theleg tubes plastic brackets 37, and intermediate portions of theback tube 47 are hinged to the back ends of thebrackets 37. Theseat tube 45 andback tube 47 are rotatably attached to therear leg tube 39 bysheet metal brackets 49. Arod 51 extending throughbrackets 49 hasspools 57 at its ends, which act as stops when the seat and back are fully opened. Therod 51 provides a stretcher forstrips 53 of flexible plastic webbing forming the seat and back of thechair 30. This construction allows the chair to be folded from an operative position shown inFIG. 1 to a folded storage position shown inFIG. 2 . This is one standard form of folding lawn chair. -
Wooden arms 29 are attached by screws to the tops ofbrackets 37. Rectangularsheet metal tubes 11, similar in cross-section to a standard curtain rod, are secured to the outboard faces of thearms 29. As shown inFIG. 3 , an inner wall of thetube 11 may be extended and bent over the forward end of thewooden arms 29 as shown at 61 then secured with screws. As shown inFIG. 7 , an outer wall of thetube 11 may be extended and bent over the rearward end of thewooden arms 29 as shown at 62 then secured with screws. - A
rectangular extension arm 19 is slidably mounted in eachtube 11. Preferably, each extension arm includes a spring-loadedstud 13 extending through anopening 14 in thearm 19 and sized to engage an opening in thetube 11, designed to hold thearm 19 in its extended position. Such spring-loaded stops are widely known and used for positioning telescoping tubes, as show, for example, in Kazmark, Sr., U.S. Pat. No. 3,998,476 and in Huang, U.S. Pat. No. 5,199,811. Alternatively, a simple stop may be provided to prevent the extension arm from pulling completely free, such as is shown in Goeke, U.S. Pat. No. 3,981,404. - Each
extension arm 19 may have an outer wall extended and bent inward as shown at 63 to accommodate aknob 27, held by a screw, as shown inFIG. 3 . - When extended, the
extension arms 19 provide support for amain tray 15. Thetray 15 includes atransverse rib 21 depending from its lower face, as shown in FIG. 7. Therib 21 stiffens the tray and prevents the tray from slipping transversely across theextension arms 19. Theknobs 27 prevent thetray 15 from sliding forward off theextension arms 19. As shown particularly inFIGS. 3-6 , this embodiment allows a user, without assistance, to convert the chair from a normal position in which the arm extensions are closed to a position in which the extended arms can support a tray situated to allow the user to eat or work in comfort. It also allows the user, carrying thetray 15, to sit down and place the tray without assistance. - As an additional feature,
transverse tubes front leg 33 andrear leg 39, respectively. Thetubes side extension arms knob 79 at its free proximal end. Thetransverse tubes side extension arms tubes FIGS. 5 and 6 , the side extension arms provide horizontal supports for aside tray 81 as shown inFIG. 6 . Thetubes back legs - It will be seen that the
side arms chair 30, and that the side tray may be easily reached while the user is seated, with or without extending theextension arms 19. When the side tray is not in use, theside arms tubes - The
chair 30 also includes aback pack 60 which acts as a receptacle for thetrays back pack 60 has apocket 90 across its upper edge for receiving a mountingrod 91. The mounting rod is mounted betweenopenings 93 at the upper end of theback tube 47. Aclosure strap 95 is preferably provided. - A second embodiment is shown in
FIGS. 7-8 . In this embodiment, afolding chair 130, which may be the same general type shown inFIGS. 1-6 , hasarm extensions 113 which are hinged at the fronts of the chair'sarms 129. Thearm extension 113 may be part of anextension assembly 111 including asupplemental arm 112 and thearm extension 113. - The
supplemental arm 112 is illustratively a block of wood having a length and width similar to those of the chair'sarm 129. Thesupplemental arm 112 may be held to thestructural arm 129 of thechair 130 by Velcro straps, or by bolts run through holes bored through thearms 129 andsupplemental arms 112 and secured by nuts, or by screws extending through thearms 129 and into thewooden arms 112. A cross-bore is provided at the forward end of thesupplemental arm 112. Preferably, thesupplemental arm 112 extends a short distance ahead of thestructural arm 129, for reasons which will become apparent. - The
arm extension 113 is channel-shaped, havingsides 116 and aweb 118. Holes in thesides 116 align with the cross bore of thesupplemental arm 112, permittingbolts 120 to pass through the holes and cross bore; thebolt 120 acts as a hinge pin. Atongue 124 on the end of thearm extension 113 engages the lower face of thesupplemental arm 112 when thearm extension 113 is opened and gives it support. It will be appreciated that other supports may be provided, such as a slide-out support mounted to the bottom of thesupplemental arm 112. Aprotrusion 126 on the outside of the outerarm extension side 116 provides a hand-hold for flipping the arm extension from a closed to open position. It also acts as a stop for engaging a forward foot on the tray and preventing the tray from sliding forward off thearm extension 113. - It will be seen that this embodiment also allows a user, without assistance, to convert the chair from a normal position in which the arm extensions are closed to a position in which the extended arms can support a tray situated to allow the user to eat or work in comfort.
- As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
- For example, in embodiments, the arm extensions may be slidably mounted in the structural arm tubes of the chair. In other embodiments, the arm extensions are detachably attached to the chair arms, as by hook-and-loop straps or by snapping onto the chair arms, either with or without folding or sliding relative to the chair arms.
- The frame of the chair may take many forms, including those presently known in the art, such as those shown in
FIGS. 13A-L and those developed hereafter. The chair may, less preferably, be a lounge chair having an extended seat supporting the user's legs or a beach chair having shorter legs. The chair may have wooden or plastic slats defining the back support or seat surface, or both. The tubular frame is preferably made of round aluminum tubing, but may be of other materials and other cross-sectional shapes such as rectangular. - The arm extensions may be made of other materials, such as wood or plastic. The tray or the arm extension or both may have interconnections to keep the tray from sliding forward, left, or right; many such interconnections are known or will be immediately envisioned, like grooves in the bottom of the tray or protrusions on the arm extensions. The chair may, in some embodiments, may have arms but not be a folding chair.
- These variations are merely illustrative.
