  • the slotted channels are configured to retain an object or accessory, in this example a basket 132 seen in Figure 5 when the seat members are in their raised positions; however, this is not strictly required and the object may be another type of selectively hidden accessory in other embodiments.
  • the seat assembly 68 may thus be said to function as an accessory holder, in this example a basket holder.
  • the basket 132 in this example has a pair of spaced-apart elongate members, in this example rods 134 and 136.
  • the rods have spaced-apart ends shaped to be received within the slotted channels of the basket retaining members, as seen by end 138 of rod 134 being received within slotted channel 128 of basket retaining member 118 in Figure 6.
  • Each of the ends of the rods includes an annular channel 140 shaped to be received by slots 130 with adjacent shoulders 142 and 144 thereof inhibiting dislodgement of the rods from the channels.
  • the basket 132 further includes a flexible member 146 that is in the shape of a hollow rectangular prism in this example with an open top 148.
  • the flexible member is of fabric or other sheet-like material and has sleeves 150 and 152 through the rods 134 and 136 extend, the rods thus functioning to retain and suspend the flexible member in place.

  • Housings 172 are generally midway between corners 127 and 129 of the retaining members and are aligned by the inner ends 106 of the seat members in this example. As seen in Figure 3, receptacles 98 and 100 are shaped to receive the housings 172 when the seat members 102 and 104 are in their lowered positions. When the seat members are lowered, housings 172 abut against pins 166 and 168, causing the pins to retract inwards. As the seat members continue to be lowered, apertures 170 eventually align with the pins, enabling the pins to extend outwards and into the apertures for retaining the seat members 102 and 104 in their lowered positions as seen in Figures 1 and 2.
  • the catch mechanism 164 includes a push-button 174 that is operatively connected to the pins 166 and 168. Actuation of the push-button downwards causes the pins to retract, thereby freeing the seat members to move to their raised positions.
  • Push-button 174 is between the seat members 102 and 104 and is centrally located on elevated portion 95 of the base 70 of the seat assembly 68 in this example.

  • the link members 208, 210, 212 and 214 have second ends which pivotally couple to respective ones of the inner sides of the seat members. This is shown in Figure 8 by second end 226 of the link member 214 pivotally coupling to retaining member 120.1 adjacent to inner side 206 and front peripheral portion 224 of seat member 104.1 of the seat assembly 68.1.

Like parts have like numbers and functions as the walker apparatus 20.1 shown in Figures 7 to 9 with decimal extension ".2" replacing decimal extension ".1" and being added for parts not previously having decimal extensions. Walker apparatus 20.2 is substantially the same as walker apparatus 20.1 shown in Figures 7 to 9 with the following exceptions.
  • Tray 180.2 in this embodiment includes a collapsible peripheral wall 246.
  • the wall extends about the rear 190.2, front 192.2 and sides 186.2 and 188.2 of the tray and extends upwards from the rim 194.2 of the tray when the seat members 102.2 and 104.2 are in their at least partially raised positions.
  • the wall 246 has a lower peripheral edge 247 which in this example couples to rim 194.2.
  • the wall has an upper peripheral edge 249 spaced-apart from the lower peripheral edge thereof.
  • the wall 246 includes a plurality of elongate, rounded corner supports.
  • corner supports 248 and 250 in Figure 10 which are adjacent to the inner side 206.2 of seat member 104.2.
  • the corner supports are flexible, arc-shaped in top profile in this example, and extend between the lower peripheral edge 247 and the upper peripheral edge 249 of the wall.
  • the wall 246 further includes a plurality of flexible planar members, in this example flexible meshes. This is shown by mesh 252 extending between supports 248 and 250 and between the lower peripheral edge 247 and upper peripheral edge 249 of the wall.
  • Each mesh is made of fabric in this example; however, this is not strictly required and the mesh may be made of other materials such as plastic or the like, in other example.
  • the wall 246 may function to inhibit food from falling off of the tray 180.2, for example.
  • Seat assembly 68.2 does not include a catch mechanism in this example.
  • the recessed region 80.2 of the base 70.2 of the seat assembly 68.2 is substantially in the shape of a rectangular prism in this example.
  • the recessed region of the base of the seat assembly extends between sides 26.2 and 28.2, rear 22.2 and front 24.2 of the walker apparatus 20.2 in this example.
  • the recessed region 80.2 of the base 70.2 of the seat assembly 68.2 is shaped to receive the tray 180.2 when the seat members 102.2 and 104.2 are in their lowered positions seen in Figure 14.
  • the wall 246 of the tray 180.2 is folded at least in part and positioned below the seat members 102.2 and 104.2 when the seat members are in their lowered positions.
  • the meshes 252 and corner supports 248 and 250 of the wall fold inwards in this example so as to abut the upper surface 182.2 of tray 180.2 when the seat members are in their lowered positions.
  • the wall 246 extends in a substantially planar manner when the seat members 102.2 and 104.2 are in their lowered positions in this example.
  • the tray 180 is substantially hidden beneath the seat members 102.2 and 104.2 of the seat assembly 68.2 in this embodiment when the seat members are in their lowered positions.
  • the seat assembly 68.2 further includes a pair of connecting members, in this example a pair of inner link members 254 and 256.
  • first ends 258 and 260 of the link members 254 and 256 pivotally couple to inner sides 204.2 and 206.2 of seat members 102.2 and 104.2 at locations between the rear and front peripheral portions of the seat members in this example.
  • Second ends 262 and 264 of the link members pivotally couple to upper peripheral edge 249 of the wall 246 adjacent to sides 186.2 and 188.2, respectively, of the tray 180.2.
  • each of the outer link members has a slot extending therethrough adjacent to its second end thereof in this example. This is seen by slot 266 extending through outer link member 212.2 adjacent to its end 226.2.
  • the seat members of the seat assembly 68.2 pivotally couple to the outer link members via protrusions which extend through and slidably along said slots in this example. This is shown by protrusion 268 of seat member 104.2 slidably extending through slot 266 of link member 212.2.
  • the connectors that actuates lowering of the trays described herein can be in various configurations, not limited to link members or hinge rods.
  • the connectors may be a piano-type hinge.
  • the specific positioning of the link members or connectors is not strictly required either, as they may be either located on both sides of the tray or at the center thereof, for example.
  • the tray 180 in an alternative embodiment may be selectively removeable in order to lower the seat members 102.1 and 104.1 of seat assembly 68.1 of the walker apparatus 20.1. It will also be understood by someone skilled in the art that many of the details provided above are by way of example only and are not intended to limit the scope of the invention which is to be determined with reference to at least the following claims.

Abstract

L'invention concerne un ensemble de siège pour un ambulateur. L'ensemble de siège comprend une paire d'éléments de siège. Chacun des éléments de siège est sélectivement mobile entre une position abaissée dans laquelle les éléments de siège s'étendent dans une direction sensiblement horizontale à une position supérieure dans laquelle les éléments de siège s'étendent dans une direction sensiblement verticale. Les éléments de siège sont configurés pour retenir un objet quand ils sont dans leurs positions supérieures. L'objet peut être un accessoire tel qu'un panier, un plateau ou autre, par exemple.
