DETAILED DESCRIPTION
A portable folding seat generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 11.
Structure and Relationship of Parts:
Referring to FIG. 1, portable folding seat 10 includes a body 12 on which is positioned a seat 14. Referring to FIG. 2, seat 14 has a first side edge 16, a second side edge 18, a front edge 20 and a rear edge 22. Referring to FIG. 4, a first arm 24 is connected by a first hinge 26 to body 12 along first side edge 16 of seat 14, and a second arm 36 is connected by a second hinge 38 to body 12 along second side edge 18 of seat 14.
Referring to FIG. 3, first arm 24 and second arm 36 each have a top edge 28, a bottom edge 30, a front edge 32 and a rear edge 34. First arm 24 and second arm 36 are pivotally moveable between an operative position shown in FIG. 4, and a stored position shown in FIG. 5 by means of first hinge 26 and second hinge 38, respectively. Referring to FIG. 4, foot rest receiving channels 80 are attached along first side edge 16 of seat 14, and along second side edge 18 of seat 14.
First hinge 26 is connected between the corresponding channel 80, and hinge 38 is connected between second side edge 18 of seat 14 or an optional spacer 39 and channel 80 and an optional spacer 39, attached to the inner side of second channe170. The purpose is to allow second arm 36 to be on a higher plane above seat 14 when pivoted about second hinge 38 compared with when first arm 24 is pivoted about first hinge 26, while still allowing the components discussed below to be attached to second arm 36. Referring to FIG.
3, a back 48 is connected by a third hinge 50 to body 12 along rear edge 34 of seat 14.
Back 48 is pivotally moveable between an operative position shown in FIG. 3 and a stored position shown in FIG. 9 by means of third hinge 50. Third hinge 50 is designed such that, when back 48 is pivoted about third hinge 50, back 48 is on a higher plane above seat 14 than first arm 24 or second arm 36. Seat 14 and back 48 may also have a belt restraint (not shown) to hold small children safely within portable folding seat 10.
Referring to FIG. 4, each hinge 26, 38 and 50 is connected to first arm 24, second arm 36 and back 48 such that, referring to FIG. 6, the stored position for first arm 24 is along a first plane parallel to seat 14, the stored position for second arm 36 along a second plane parallel to the first plane and seat 14, and the stored position for back 48 is along a third plane parallel to the first plane, the second plane and seat 14. This may be done by either positioning the hinges on different planes, such as between hinge 50 and hinges 26 and 38, or by positioning the hinge a certain distance from the part to be folded, such as between hinge 26 and hinge 38. In addition, by varying the position of the hinges, the relative position of each stored part may be varied. For example, one may have back 48 be on a plane closer to seat 14 compared with first arm 24 or second arm 36. With the configuration as shown, first arm 24 with lower support 60 and upper support 58 fold against top of seat 14, second arm 36 with lower support 60 and upper support 58 fold against first arm 24 and back 48 folds against arm 36. Sides of tray 69 fit into quadrants of hinges 26 and 38 and aligned with channels 70 and 80.
Referring to FIG. 2, in the operative position, latches 52 are provided to connect first arm 24 and second arm 36 to back 48. Latches 52 serve as means for selectively locking first arm 24, second arm 36 and back 48 in the operative position.
Referring to FIG. 1, portable folding seat 10 is attached to tabletop 56 by elongated upper supports 58 and elongated lower supports 60. An elongated upper support 58 is connected to front edges 32 of first arm 24 and second arm 36, respectively, to engage the top 54 of tabletop 56. Each upper support 58 is rotatably connected to first arm 24 and second arm 36, such that upper supports 58 have an operative position shown in FIG. 1 and a stored position shown in FIG. 3. As shown, a tube 62 is connected to each upper support 58.
Alternatively, referring to FIG. 12, upper support 58 may be slidably received by a tube 62.
It will be understood that upper support 58 and tube 62 may be replaced by a single piece that slides along a track, for example. Tube 62 has a groove 59 that is engaged by anchor rails 66 such that tube 62 is supported within an outer channel 64. Tube 62 is held in the stored position and the operative position by spring-loaded balls or dowel pins 65 that engage orifices in either tube 62 or outer channel 64, depending on their orientation. Upper supports 58 may then be rotated within outer channels 64, and held in the desired position by balls 58.
Alternatively, upper supports 58 may be moved between the two positions by providing tube 62 with a square cross-section and outer channels 64 with a similar cross-section (not shown).
Tube 62 may then be removed, rotated to the desired orientation, re-inserted into outer channe164, and fixed into place by a locking pin. Other ways of making upper support 58 rotatable will be apparent to those skilled in the art. If a tray 69 is provided as shown, upper supports 58 may be used to clamp tray 69 to tabletop 56. Referring to FIG. 12, while upper support 58 is shown as being flat, it may also have a raised portion 57 to receive either raised edge of tabletop 56 or the raised edge of tray 69, or other useful profile, as will be recognized by those skilled in the art.
Referring to FIG. 12, upper support 58 may also be slidably connected to portable folding seat 10. In this embodiment, upper supports 58 are slidably connected to top edges 28 of first arm 24 and second arm 36. Each upper support 58 slides into channe162, which is attached to the corresponding top edge 28 of arms 24 and 36. Upper support 58 may have a spring-loaded locking mechanism similar to the one described above.
Referring to FIG. 1, elongate lower supports 60 are connected to bottom edges 30 of 5 arms 24 and 36 and extend past upper supports 58. Lower supports 60 are adapted to engage bottom 68 of tabletop 56 with pads 73, and work in concert with upper supports 58 to support body 12. A lower support receiving channel 70 is connected to bottom edges 30 of either first arm 24, second arm 36, or both. Lower supports 60 are slidably engaged by channel 70 to either first arm 24, second arm 36, or both, such that each lower support 60 has an operative position shown in FIG. 1 and a stored position shown in FIG. 3. Lower supports 60 are also telescopically extendable upward to engage bottom 68 of tabletop 56. Referring to FIG. 11, lower support 60 may be extended upward by means of a screw 86 and adjustment knob 88 combination. The outward extension of lower support 60 may be controlled by an extension limiting rod 90 that is adjusted by a knob 92. Rod 90 is located inside channel 70 and lower support 60, with knob 921ocated at the back of channel 70. Other means of positioning lower support 60 will be recognized by those skilled in the art. As shown in FIG. 1, lower supports 60 preferably extend past upper supports 58 to provide a more stable connection.
Referring to FIG. 1, a foot rest 72 is attached to body 12 by a foot rest support 74 that extends below seat 14. Foot rest support 74 includes hinges 76 and rigid elongate portions 78.
Foot rest support receiving channels 80 are attached to edge 16 of seat 14 and edge 18 of seat 14. Hinges 76 and elongate portions 78 are adapted to be received by each receiving channels 80, such that elongate portion 78 pivots about hinge 76 until it is oriented to be slid into receiving channel 80. Using this design, foot rest 72 has an operative position shown in FIG.
4 and a storage position shown in FIG. 7. A child restraint strap 81 is included as shown in FIG. 4.
It will be understood that, when manufactured, the components described above may be integrally combined with any other components such as by using plastic molds, rather than discrete components that are attached.

DETAILED DESCRIPTION
A portable folding seat generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 11.
Structure and Relationship of Parts:
Referring to FIG. 1, portable folding seat 10 includes a body 12 on which is positioned a seat 14. Referring to FIG. 2, seat 14 has a first side edge 16, a second side edge 18, a front edge 20 and a rear edge 22. Referring to FIG. 4, a first arm 24 is connected by a first hinge 26 to body 12 along first side edge 16 of seat 14, and a second arm 36 is connected by a second hinge 38 to body 12 along second side edge 18 of seat 14.
Referring to FIG. 3, first arm 24 and second arm 36 each have a top edge 28, a bottom edge 30, a front edge 32 and a rear edge 34. First arm 24 and second arm 36 are pivotally moveable between an operative position shown in FIG. 4, and a stored position shown in FIG. 5 by means of first hinge 26 and second hinge 38, respectively. Referring to FIG. 4, foot rest receiving channels 80 are attached along first side edge 16 of seat 14, and along second side edge 18 of seat 14.
First hinge 26 is connected between the corresponding channel 80, and hinge 38 is connected between second side edge 18 of seat 14 or an optional spacer 39 and channel 80 and an optional spacer 39, attached to the inner side of second channe170. The purpose is to allow second arm 36 to be on a higher plane above seat 14 when pivoted about second hinge 38 compared with when first arm 24 is pivoted about first hinge 26, while still allowing the components discussed below to be attached to second arm 36. Referring to FIG.
3, a back 48 is connected by a third hinge 50 to body 12 along rear edge 34 of seat 14.
Back 48 is pivotally moveable between an operative position shown in FIG. 3 and a stored position shown in FIG. 9 by means of third hinge 50. Third hinge 50 is designed such that, when back 48 is pivoted about third hinge 50, back 48 is on a higher plane above seat 14 than first arm 24 or second arm 36. Seat 14 and back 48 may also have a belt restraint (not shown) to hold small children safely within portable folding seat 10.
Referring to FIG. 4, each hinge 26, 38 and 50 is connected to first arm 24, second arm 36 and back 48 such that, referring to FIG. 6, the stored position for first arm 24 is along a first plane parallel to seat 14, the stored position for second arm 36 along a second plane parallel to the first plane and seat 14, and the stored position for back 48 is along a third plane parallel to the first plane, the second plane and seat 14. This may be done by either positioning the hinges on different planes, such as between hinge 50 and hinges 26 and 38, or by positioning the hinge a certain distance from the part to be folded, such as between hinge 26 and hinge 38. In addition, by varying the position of the hinges, the relative position of each stored part may be varied. For example, one may have back 48 be on a plane closer to seat 14 compared with first arm 24 or second arm 36. With the configuration as shown, first arm 24 with lower support 60 and upper support 58 fold against top of seat 14, second arm 36 with lower support 60 and upper support 58 fold against first arm 24 and back 48 folds against arm 36. Sides of tray 69 fit into quadrants of hinges 26 and 38 and aligned with channels 70 and 80.
Referring to FIG. 2, in the operative position, latches 52 are provided to connect first arm 24 and second arm 36 to back 48. Latches 52 serve as means for selectively locking first arm 24, second arm 36 and back 48 in the operative position.
Referring to FIG. 1, portable folding seat 10 is attached to tabletop 56 by elongated upper supports 58 and elongated lower supports 60. An elongated upper support 58 is connected to front edges 32 of first arm 24 and second arm 36, respectively, to engage the top 54 of tabletop 56. Each upper support 58 is rotatably connected to first arm 24 and second arm 36, such that upper supports 58 have an operative position shown in FIG. 1 and a stored position shown in FIG. 3. As shown, a tube 62 is connected to each upper support 58.
Alternatively, referring to FIG. 12, upper support 58 may be slidably received by a tube 62.
It will be understood that upper support 58 and tube 62 may be replaced by a single piece that slides along a track, for example. Tube 62 has a groove 59 that is engaged by anchor rails 66 such that tube 62 is supported within an outer channel 64. Tube 62 is held in the stored position and the operative position by spring-loaded balls or dowel pins 65 that engage orifices in either tube 62 or outer channel 64, depending on their orientation. Upper supports 58 may then be rotated within outer channels 64, and held in the desired position by balls 58.
Alternatively, upper supports 58 may be moved between the two positions by providing tube 62 with a square cross-section and outer channels 64 with a similar cross-section (not shown).
Tube 62 may then be removed, rotated to the desired orientation, re-inserted into outer channe164, and fixed into place by a locking pin. Other ways of making upper support 58 rotatable will be apparent to those skilled in the art. If a tray 69 is provided as shown, upper supports 58 may be used to clamp tray 69 to tabletop 56. Referring to FIG. 12, while upper support 58 is shown as being flat, it may also have a raised portion 57 to receive either raised edge of tabletop 56 or the raised edge of tray 69, or other useful profile, as will be recognized by those skilled in the art.
Referring to FIG. 12, upper support 58 may also be slidably connected to portable folding seat 10. In this embodiment, upper supports 58 are slidably connected to top edges 28 of first arm 24 and second arm 36. Each upper support 58 slides into channe162, which is attached to the corresponding top edge 28 of arms 24 and 36. Upper support 58 may have a spring-loaded locking mechanism similar to the one described above.
Referring to FIG. 1, elongate lower supports 60 are connected to bottom edges 30 of 5 arms 24 and 36 and extend past upper supports 58. Lower supports 60 are adapted to engage bottom 68 of tabletop 56 with pads 73, and work in concert with upper supports 58 to support body 12. A lower support receiving channel 70 is connected to bottom edges 30 of either first arm 24, second arm 36, or both. Lower supports 60 are slidably engaged by channel 70 to either first arm 24, second arm 36, or both, such that each lower support 60 has an operative position shown in FIG. 1 and a stored position shown in FIG. 3. Lower supports 60 are also telescopically extendable upward to engage bottom 68 of tabletop 56. Referring to FIG. 11, lower support 60 may be extended upward by means of a screw 86 and adjustment knob 88 combination. The outward extension of lower support 60 may be controlled by an extension limiting rod 90 that is adjusted by a knob 92. Rod 90 is located inside channel 70 and lower support 60, with knob 921ocated at the back of channel 70. Other means of positioning lower support 60 will be recognized by those skilled in the art. As shown in FIG. 1, lower supports 60 preferably extend past upper supports 58 to provide a more stable connection.
Referring to FIG. 1, a foot rest 72 is attached to body 12 by a foot rest support 74 that extends below seat 14. Foot rest support 74 includes hinges 76 and rigid elongate portions 78.
Foot rest support receiving channels 80 are attached to edge 16 of seat 14 and edge 18 of seat 14. Hinges 76 and elongate portions 78 are adapted to be received by each receiving channels 80, such that elongate portion 78 pivots about hinge 76 until it is oriented to be slid into receiving channel 80. Using this design, foot rest 72 has an operative position shown in FIG.
4 and a storage position shown in FIG. 7. A child restraint strap 81 is included as shown in FIG. 4.
It will be understood that, when manufactured, the components described above may be integrally combined with any other components such as by using plastic molds, rather than discrete components that are attached.
Operation:
Referring to FIG. 1 through 11, portable folding seat 10 is provided as described above. Referring to FIG. 6, 8 and 9, folding seat 10 is shown in the stored position to facilitate storage or transportation. Referring to FIG. 5, when folding seat 10 is desired to be used, back 48 is pivoted about hinge 50 to its operative position. Arm 36 is then pivoted about hinge 38 and arm 24 is pivoted about hinge 26 to their respective operative positions and secured to back 48 by latches 52. To avoid interference between arm 24 and back 48, arm 36 is secured to back 48 by latches 52 after arm 24 is in its operative position. Referring to FIG. 7 foot rest 72 is moved from its storage position to the operative position shown in FIG. 3 by pulling foot rest 72 such that each elongate portion 78 of foot rest support 74 slides out from channel 80 until hinge 76 also exits channel 80. Foot rest 72 is then free to swing down. Foot rest 72 may be adjusted to the desired position based on the length of the child's legs, and secured by latches on under side of foot rest 72, such as through graduated slots 77 in elongate portion 78 as shown in FIG. 4.
Referring to FIG. 1, lower supports 60 are raised to their operative position in conjunction with arms 24 and 36. Lower supports 60 are slid outward from seat 14 along channel 70 and are adjusted to the approximate height that will allow them to engage bottom 68 of tabletop 56. Lower supports 60 are then extended and situated behind the sill on bottom 68 of tabletop 56. Upper supports 58 are then rotated (or slid out using the embodiment in FIG. 12) from their stored position over top edges 28 as shown in FIG. 2, to their operative position over tabletop 56. Upper supports 58 are held in place by caged spring-loaded balls or dowel pins 66 that engage orifices in the sides of channe162. If desired, tray 69 is received by upper supports 58 on tabletop 56. Referring to FIG. 10, an example of a suitable tray 69 is shown, with channels 75 that receive upper supports 58. Instead of channels 75, tray 69 may have a sufficiently low leading edge. Referring to FIG. 1, lower supports 60 are positioned against sill on bottom 68 of tabletop 56, and front edges 32 are positioned against edge 54 of tabletop 56. A final adjustment of lower supports 60 is then made to level body 12 of folding seat 10. Extension limiting rods 90 are adjusted to secure folding seat 10 to top 54. Once supports 60 have been properly adjusted, adjustment on subsequent uses may not be necessary each time folding seat 10 is attached to a tabletop of the same thickness. Folding seat 10 is not intended to be used on a table without a sill on the bottom, however a short sill can easily be attached to the bottom of tabletop, such as a short board with a thickness of about.75".
To return folding seat 10 to its storage position, the extension limiting rods are slackened, tray 69 is removed, and upper supports 58 are returned to their storage position over top edges 28 as shown in FIG. 3 by releasing the spring-loaded catch 66.
Referring to FIG. 5, folding seat 10 is removed from table 56, and foot rest 72 is returned to its stored position. Lower supports 60 are returned to their stored position, latches 52 are released, and arms 24, 36, and back 48 are returned to their stored position as shown in FIG. 6 and 7. In its stored position, folding seat 10 may be nested within tray 69, which may be appropriately sized to closely receive seat 10, by engaging tongue 82 with a slot 84 on tray 69. Since channels 75 are raised from the bottom of tray 69, this may also form a space for storing small items sueh as utensils, bib, etc. Additional space may be obtained if channels 80 extend below seat 14. Folding seat 10 may then be secured to tray 69 by threading child restraint strap 81 (shown in FIG. 4) through slots 84 and securing it. When attached with chair 10 in the folded position, the child restraint straps 81 provide a handle for carrying or hanging.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope defined in the Claims.
Referring to FIG. 1, lower supports 60 are raised to their operative position in conjunction with arms 24 and 36. Lower supports 60 are slid outward from seat 14 along channel 70 and are adjusted to the approximate height that will allow them to engage bottom 68 of tabletop 56. Lower supports 60 are then extended and situated behind the sill on bottom 68 of tabletop 56. Upper supports 58 are then rotated (or slid out using the embodiment in FIG. 12) from their stored position over top edges 28 as shown in FIG. 2, to their operative position over tabletop 56. Upper supports 58 are held in place by caged spring-loaded balls or dowel pins 66 that engage orifices in the sides of channe162. If desired, tray 69 is received by upper supports 58 on tabletop 56. Referring to FIG. 10, an example of a suitable tray 69 is shown, with channels 75 that receive upper supports 58. Instead of channels 75, tray 69 may have a sufficiently low leading edge. Referring to FIG. 1, lower supports 60 are positioned against sill on bottom 68 of tabletop 56, and front edges 32 are positioned against edge 54 of tabletop 56. A final adjustment of lower supports 60 is then made to level body 12 of folding seat 10. Extension limiting rods 90 are adjusted to secure folding seat 10 to top 54. Once supports 60 have been properly adjusted, adjustment on subsequent uses may not be necessary each time folding seat 10 is attached to a tabletop of the same thickness. Folding seat 10 is not intended to be used on a table without a sill on the bottom, however a short sill can easily be attached to the bottom of tabletop, such as a short board with a thickness of about.75".
To return folding seat 10 to its storage position, the extension limiting rods are slackened, tray 69 is removed, and upper supports 58 are returned to their storage position over top edges 28 as shown in FIG. 3 by releasing the spring-loaded catch 66.
Referring to FIG. 5, folding seat 10 is removed from table 56, and foot rest 72 is returned to its stored position. Lower supports 60 are returned to their stored position, latches 52 are released, and arms 24, 36, and back 48 are returned to their stored position as shown in FIG. 6 and 7. In its stored position, folding seat 10 may be nested within tray 69, which may be appropriately sized to closely receive seat 10, by engaging tongue 82 with a slot 84 on tray 69. Since channels 75 are raised from the bottom of tray 69, this may also form a space for storing small items sueh as utensils, bib, etc. Additional space may be obtained if channels 80 extend below seat 14. Folding seat 10 may then be secured to tray 69 by threading child restraint strap 81 (shown in FIG. 4) through slots 84 and securing it. When attached with chair 10 in the folded position, the child restraint straps 81 provide a handle for carrying or hanging.
