Abstract

PURPOSE:To permit the easy transfer between a bed and a wheelchair without standing on a floor surface. CONSTITUTION:A wheelchair is equipped with a traveling car body 1 having castor type small diameter transmission front wheels 3 positioned on the left and right sides in the front side and the left and right large diameter rolling rear wheels 4 in pair positioned behind the front wheels 3, and equipped with a waist set type chair part 2c and a shoulder layer part 2b on the car body, also with a hand pushing type handle 6 which permits the nursing traveling in the rear part of the car body. A handrail frame 11 is constituted so as to serve as handrail when set in a rising state on the left and right sides of the car body so that the upper surface of the handrail is set on the level nearly equal to or lower than the upper surface of the waist set chair in lowering state, and a bridge 16 in which one edge side is spread to the outside lateral direction from the handrail frame part side in engagement state and can be properly suspended on the upper surface of a bed is installed on the car body side or the handrail frame side.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair for a physically handicapped person.

2. Description of the Related Art Conventionally, a running chair having a small diameter caster-type rolling front wheel located on the left and right front sides and a pair of left and right large-diameter rolling rear wheels respectively located on the rear side thereof has a stool chair portion and a backrest portion. It is well known that a wheelchair is provided with a hand-held handle for rearing the car body, and a wheelchair with a vertically adjustable handrail on both left and right sides of the car body is fair. It is disclosed in the rear of 2-62254.

SUMMARY OF THE INVENTION In the case of a conventional wheelchair, even if the wheelchair is laterally attached to the side surface of the bed, a gap is formed between the end of the seating surface of the wheelchair and the bed, which is unstable. If it is not in such a state, it is difficult to move from the wheelchair to the bed or vice versa.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a small diameter caster type rolling front wheel 3 located on the left and right front sides and a pair of left and right large diameter rolling wheels located on the rear side thereof. A wheelchair provided with a traveling vehicle body 1 having a rear wheel 4, a stool chair portion 2c and a backrest portion 2b provided on the vehicle body, and a hand-held steering wheel handle 6 at the rear portion of the vehicle body, which is capable of traveling for care. The handrail frame 11 becomes a handrail when set in a raised state on both the left and right sides of the handrail, and when the handrail is lowered, the handrail frame 11 is substantially equal to or less than the upper surface of the stool, and the handrail frame 11 is provided to A wheelchair for persons with disabilities is provided with a bridge 16 which is extended from the side of the handrail frame portion to the lateral lateral direction with one end side being in a locked state and can be appropriately suspended on the upper surface of the bed.

[Embodiment] 1 is a traveling vehicle body, and its frame 2 is a leg receiving portion 2
The a side and the backrest portion 2b side are pivotally connected to the seat portion 2c so as to be rotatable. Then, on the front left and right lower portions of the frame portion of the fixed seat portion 2c, small diameter caster type rolling front wheels 3,
3 is provided, and a pair of left and right large-diameter rolling post-transmissions 4 and 4 respectively located on the rear side of the same are pivotally supported. A seat 5 and a seat 5 such as a backrest seat or a mat are stretched between the waist receiving portion 2c and the backrest portion 2b. 6 is a handle. 7
Is a lever for operation that enables switching of the operation switching valve (not shown) of the telescopic actuator 8 by a lever to switch the leg receiving portion 2a side and the backrest portion 2b side to the phantom line state of FIG. is there. Reference numeral 9 denotes a link interlocking with the expansion and contraction operating device 8, which is operated back and forth, to which the leg receiving portion 2a is pivotally connected, and the backrest portion 2b is connected via a link 10. 11
Reference numerals a and 11b denote handrail frames, which are provided by inserting a supporting rod 13 having the handrail frame attached to a cylindrical metal 12 fixed to the frame 2 via a bracket so that the handrail frame 11 can be moved up and down. There is. A stopper 14 receives the support rod 13 so as not to descend, and is fixed to an arm 15 provided rotatably on the tubular metal 12, and switches between a stopper state located at the lower end of the metal 12 and a non-stopper state which is disengaged. It is configured to be possible. When the stopper 14 is removed from the lower portion of the metal 12 to bring it into a non-stopper state, the handrail frame 11 descends so that the upper surface of the handrail is substantially equal to or less than the upper surface of the stool. 16
Is a bridge, and in the embodiment shown in FIGS. 2 to 5, an engaging hole formed in the outer end of the handrail frame 11 and extending in the front-rear direction is formed at one end of the plate-shaped bridge. Stop frame 17
An engaging body 18 that can be engaged and disengaged is attached. The engaging member 18 has a locking piece 9 when the bridge 16 is horizontally expanded outward in the left and right directions and when the bridge 16 is suspended downward.
It is two pieces bent at 0 degrees. The operation of the above example will be described in detail. When a caregiver operates by placing a disabled person on a wheelchair, the bridge 16 is replaced by the handrail frame 11 as shown in FIG.
A locking piece along the back surface of the bridge of the engaging body 18 is hooked on the locking frame 17 and is hung so that the bridge 16 is operated without disturbing. Next, when moving from the wheelchair to the bed B, the left and right side surfaces of the wheelchair are laterally attached to the side surface of the bed B, and the handrail frame 11 located on the bed B side is removed by pressing the stopper 14 and pushed down. Set the upper surface of the chair to a position almost the same as or slightly lower than the upper surface of the chair seat. In this state, the bridge 16 is changed to the posture shown in FIG. 3 by extending the locking portion and expanding laterally outward, and the posture is changed so that the outer end side is received by the upper surface of the bed B and becomes the bridging state. Then, the handicapped person can move to the Bet B side through the bridge 16 without difficulty. On the contrary, it is possible to easily get on the wheelchair from the Bet B side. Although the bridge 16 is configured to be detachable in the above-described embodiment, as shown in FIGS. 6 and 7, the supporting rod 19 is attached to the cylindrical metal 12 through which the supporting rod 13 of the handrail frame is inserted. The handrail frame 11 may be rotatably attached thereto, or a supporting rod may be provided on the outer surface side of the handrail frame 11 so as to be rotatably attached. In any case, it suffices if the posture can be changed so that the handrail side can be bridged to the bed B side.

According to the present invention, since the handrail frame of the wheelchair can be moved up and down, and the bridge is constructed at the outer side of the handrail frame, the bridge can be bridged between the handrail frame and the bed. It becomes easy to move from the wheelchair to the bed side, and vice versa.
