Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a control device for an electric wheelchair used by a physically handicapped person, an elderly person and the like.

[0002]

[Prior art]

 An electric wheelchair is disclosed, for example, in Japanese Utility Model Publication No. 3-49697, in which a steering control box is provided on the front side of one of the armrests provided on the left and right of the seat, and in Japanese Patent Laid-Open No. 2-46107. As described, a structure is known in which a steering handle shaft is erected on the front side of the seat and an operation box is provided at the center of the upper end of the steering handle shaft.

[0003]

[Problems to be solved by the device]

 The control box and operation box of the above-mentioned electric wheelchair were provided at positions where it was easy for a person sitting in the seat to control. A disabled person or an elderly person who uses a wheelchair may fall into a state where it is difficult to perform the control operation by himself, and in that case, the caregiver operates the control box or operation box to operate the control. This is difficult and you have to disengage the drive clutch and push the wheelchair. An electric wheelchair is equipped with a motor and a battery and has a heavy vehicle body weight, which makes it difficult for a caregiver to move it by hand.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in an electric wheelchair equipped with a battery and driven by a driving force of a motor, the steering operation device 1 is repositioned in front of and behind the seat 2 to enable longitudinal operation.

[0005]

[Function and effect of the device]

 In the above configuration, when the operation control device 1 is located in front of the seat 2, the passenger sitting in the seat 2 can operate the operation control device 1 to perform operations such as advancing, stopping, turning to the left and right. When carrying out the maneuvering, the manipulating device 1 is moved to the rear of the seat 2 so that the caregiver can carry out the maneuvering while walking on the rear side of the wheelchair, which reduces the burden on the carer.

【Example】

 Next, an embodiment of the present invention will be described with reference to a first embodiment shown in FIGS. 1 to 3 and a second embodiment shown in FIG. In the first embodiment, the vehicle body 6 has a pair of left and right driving wheels 10, 10 mounted on the front side, a pair of left and right driven wheels 11, 11 mounted on the rear side, and a motor and battery mounted inside the cover 12. is doing. A seat 2 is provided above the cover 12. The left and right armrests 3, 3 are fixed to the seat 2. A foot plate 13 is attached to the lower part of the front of the seat 2 on an arm 14 extending from the seat 2.

A support arm 5 is erected from the right side of the vehicle body 6, an upper end of the support arm 5 is located in front of the armrest 3, and a control box 15 of the operation control device 1 is fixed to the upper end of the support arm 5. A joystick 16 for controlling the traveling speed and traveling direction is erected on the control box 15, and a battery charge amount display portion 17 is provided. The mounting portion of the support arm 5 to the vehicle body 6 is mounted on the vehicle body 6 with a rivet 19 as shown in FIGS. 2 and 3, and a box-shaped mounting box 20 is attached to the center of the disk 18 with a bolt 21. It is rotatably mounted, and a boss portion 26 at the lower end portion of the support arm 5 is fitted into this mounting box 20 and is pivotally supported by a pin 22.

Further, cutout grooves 23 and 24 are provided at two locations on the outer circumference of the disk 18, and a hook 25 that engages with the cutout grooves 23 and 24 is elastically attached to the support arm 5 in the engaging direction. When the hook 25 of the support arm 5 is engaged with the notch groove 23 on the front side of the disc 18, the control box 15 is fixed to the front side of the seat 2, and when the hook 25 is engaged with the notch groove 24 on the rear side, control is performed. The box 15 will be fixed to the rear side of the seat 2. Reference numeral 28 is a cap that covers the mounting portion of the support arm 5.

In the second embodiment, the armrests 3, 3 are provided so as to project from the left and right side portions of the seat 2 toward the front, but the pivotal support portion 4 of one of the armrests 3 is rotated back and forth to be in a substantially horizontal position. The control box 15 is attached to the front end of the control box 15. The mounting portion of the control box is attached to the armrest 3 with a fastener 27 so as to be rotatable and fixed. In this second embodiment, the armrest for the occupant is lost when the control box 15 is rotated backwards for the caregiver to operate, so the first embodiment is better in this respect, but the structure is It has the advantage of being simple.
