Description

The folding wheelchair

Technical field

This utility model provides a kind of wheelchair, particularly a kind of can folding and the folding wheelchair of reduced volume.

Background technology

Leaning against of general wheelchair; In order to make occupant more comfortable, adopt mostly soft materials canvas because the canvas support force is not enough; The occupant is sitting on this wheelchair; The back is resisted against this canvas when leaning against, this canvas lean against can't the stable support occupant the back, cause the occupant to take posture crooked.

Therefore, to above-mentioned disappearance, this utility model people proposes improvement and obtains Taiwan certificate count M404007 number and the novel patent of Germany's No. 202011101831.1 " wheelchair "; This wheelchair has the unit of leaning against; This leans against the unit and has outer tube, and is connected at least one of this outer tube and leans against, and the occupant is sitting on this wheelchair; The occupant back is resisted against this at least one leaning against and back that can the stable support occupant, makes the occupant keep correct status; But because the setting of this outer tube hinders folding of this wheelchair, the volume of this wheelchair can't dwindle, and carries inconvenience and takes up room collection and landed cost height.

The utility model content

The main purpose of this utility model provides a kind of folding wheelchair, and comprise body, first support bar, second support bar, lean against frame, and linkage unit.

This body has seat support portion.

This first support bar is arranged at this seat support portion dorsal part.

This second support bar is arranged at this seat support portion dorsal part, and is mutual opposition state with this first support bar.

This leans against the frame cording has first arm that can be arranged to rotation on this first support bar, can be arranged to rotation second arm on this second support bar; Reach two and be connected to leaning against of this first arm and this second arm, the free-end of this first arm has long open-work.

This linkage unit has the interior pipe that is socketed on this first arm free-end inner edge surface and this second arm free-end inner edge surface, the outer tube that is socketed on this first arm free-end outer edge surface and this second arm free-end outer edge surface, and pulling piece; Should have screw by interior pipe; This outer tube has perforation; This pulling piece have the articulated section, with the reverse pulling part that is provided with in this articulated section, and the long bolt that articulates with this articulated section; This long bolt pass this outer tube this perforation, this first arm this long open-work and be bolted in this screw of pipe in this, make pipe and this first arm of the common socket packing of this outer tube and this second arm in this.

This linkage unit can be removed the socket packing state to this first arm and this second arm; Make this first arm and the separated attitude of this second arm and outside rotation respectively; Be beneficial to folding of this wheelchair; The volume of this wheelchair can dwindle, and is easy to carry and do not take up room, and collection and landed cost are low.

The specific embodiment

At first, see also Fig. 1,2 and 3, this utility model wheelchair comprises body 10, first support bar 20, second support bar 30, leans against frame 40 and linkage unit 50.

This body 10, have can deflection seat support portion 11, two front-wheel 12, two that is installed on these seat support portion 11 belows be arranged at the trailing wheel 13 of these seat support portion 11 dual-sides, and can open or fold the interlock unit 14 of this wheelchair.

This first support bar 20 is arranged at this seat support portion 11 dorsal parts, and these first support bar, 20 top bendings form the first in command 21.

This second support bar 30 is arranged at this seat support portion 11 dorsal parts, and is mutual opposition shape with this first support bar 20, and these second support bar, 30 top bendings form the second in command 31.

This leans against frame 40, have first arm 41 that can be arranged to rotation on this first support bar 20, can be arranged to rotation second arm 42 on this second support bar 30, and two be connected to this first arm 41 and this second arm 42 lean against 43.Wherein, the free-end of this first arm 41 has long open-work 411.

This linkage unit 50 has the interior pipe 51 that is socketed on these first arm, 41 free-end inner edge surfaces, the outer tube 52 that is socketed on these first arm, 41 free-end outer edge surfaces, liner 53, and pulling piece 54.

Should interiorly manage 51, have screw 511.

This outer tube 52 has arc recess 521, and runs through the perforation 522 of this arc recess 521.

This liner 53 is posted by this arc recess 521.

This pulling piece 54, have articulated section 541, with this articulated section 541 reverse pulling parts 542 that are provided with, and the long bolt 543 that articulates with this articulated section 541.This long bolt 543 wear group this liner 53, this outer tube 52 this perforation 522 and this first arm 41 this long open-work 411 and be bolted in this interior this screw 511 of 51 of managing, this articulated section 541 is posted by this liner 53.

See also Fig. 4,5,6 and 8, when using this wheelchair, move this interlock unit 14 to make this wheelchair become open configuration (as shown in Figure 1); With these first arm, 41 inside rotations; These second arm, 42 inside rotations make this two backrest 43 between this first support bar 20 and this second support bar 30, and make these first arm, 41 free-ends and this second arm, 42 free-ends linearly involutory; This long bolt 543 moves in this long open-work 411 and can this linkage unit 50 of displacement; Make this interior pipe 51 be socketed on these first arm, 41 free-end inner edge surfaces and this second arm 42 free-end inner edge surfaces, this outer tube 52 is socketed on these first arm, 41 free-end outer edge surfaces and this second arm 42 free-end outer edge surfaces (as shown in Figure 8), pulls this pulling part 542; Make this pulling part 542 near this outer tube 52; This long bolt 543 spurs manages the 51 directions displacements towards this pulling piece 54 in this, and then packing this first arm 41 and this second arm 42, and this first arm 41 and this second arm 42 be this outer tube 52 of packing again; This first arm 41 and this second arm 42 are firmly seized on both sides by the arms in this between pipe 51 and this outer tube 52; Make this wheelchair become supply using the state of taking, be resisted against this for the occupant back and two lean against 43, stable support occupant's back.
