Description

[Detailed description of the invention] [Industrial application field] This invention relates to a chair for physically disabled people.

[Conventional technology]

For physically disabled people who are unable to get into a car on their own, they are carried by a caregiver.

[Problems to be solved by the invention] When a physically disabled person gets on and off the vehicle while holding the person, the posture of the physically disabled person becomes unstable, which creates a sense of fear.

Furthermore, when getting off the train, one has to insert one's hand between the handicapped person and the seat to hold him, which can be difficult due to the lack of space and the weight of the handicapped person.

Furthermore, after carrying the child indoors, the person had to sit on a chair, which was a time-consuming problem.

In order to solve the above-mentioned problems, this invention has a seat frame, two rows of support rods that are sloped upwards toward the front on both sides of the seat frame, and two rows of support rods that are installed in the middle of both support rods. A seat, a seat frame body, and a bucket attached to the seat frame body, comprising a recessed part provided so that the top surface is open and an engaging part located on the rear side of the recessed part and provided on the receiving rod. When the bucket seat and the recesses provided in both corners of the front edge of the lower surface of the bucket seat so that the ends of both support rods fit into them, and the recesses and the ends of the support rods are fitted on both sides of the seat frame body. A projection provided to fit into the recessed portion, a slidable slider fitted to the outside halfway on both sides of the seat frame, a spring that pushes the slider back toward the recessed portion, and both sliders locked to the engaging portion. It consists of an engaging part provided to

[Effect]

When loading a disabled person into a car, the disabled person is seated on a bucket seat, and the disabled person is lifted up along with the seat and placed onto the car seat.

In addition, when the person is removed from the car, the person with a physical disability is brought into the room along with the seat, and the tip of the support rod of the seat is fitted into the recess of the bucket seat.
The seat is placed on the seat by fitting the protrusion of the seat frame into the recess of the support rod.

Then, when the operating member is pushed down and both sliders are pulled back, and the operating member is then released, the slider is pushed back by the spring and both engaging portions are engaged, and the seat is attached and the seat is seated. Become a child.

〔Example〕

In the figure, A is a locus.

The above seat A is the seat frame 1 as shown in Figure 3.
There are two rows of support rods 2 installed on the upper side of both sides of the seat frame 1 and attached to the seat frame 1 so as to slope upwardly toward the front. It is comprised of a recessed part 3 provided so as to be opened, and an engaging part 4 provided on the receiving rod 2 and located on the rear side of this recessed part 3.

The recessed part 3 and the engaging part 4 are received in a through hole 6 of a synthetic resin molded part 5, which has a recessed part 3 on the top surface and a protrusion for the engaging part 4 on the rear surface, as shown in FIG. A frame rod 2 is passed through the frame, and a molded part 5 is fixed to the frame rod 2 with rivets 7.

Note that the seat frame 1 is formed by positioning both ends of the rear U-shaped frame 9 on the outside of both ends of the front U-shaped frame 8, and connecting the wrapping portions rotatably via pins 10.
Further, the ends of the connecting rods 11 side of both support rods 2, 2 connected via the connecting rods 11 are rotatably attached to the upper ends of the projections 12 rising from both sides of the rear U-shaped frame 9 via pins 13, Furthermore, if both ends of the swinging rod 15 are rotatably connected to the tips of the receiving rods 2, 2 and both sides of the front U-shaped frame 8 via pins 14, the inner side of the rear U-shaped frame 9 By bending the front U-shaped frame 8 and lowering the tip of the support rod 2, the seat A can be folded to a low volume as shown in FIG.

B is the seat.

The above seat B consists of a seat frame 16 and a seat frame 1.
A bucket seat 17 attached to the upper side of the bucket seat 17 and a recess 18 provided in both corners of the front edge of the lower surface of the bucket seat 17 so that the ends of both support rods 2 fit into the corners.
The recess 18 and the receiving rod 2 are provided on both sides of the seat frame body 16.
a protrusion 19 provided to fit into and lock into the recessed portion 3 when the tips of the sliders 20 and 20 are slidably fitted to the outside of the seat frame 16 midway on both sides;
, a spring 21 that pushes back the slider 20 in the direction of the distal end of the receiving rod 2, and an engaging portion 4 attached to the slider 20.
It consists of an engaging part 22 provided to prevent the seat frame body 16 from lifting up, and an operating member 23 that connects both sliders 20. As shown in FIG. The protrusion 19 falls down, and then the slider 2
When the pullback of 0 is released, the slider 20 is pushed back by the spring 21, and the engaging part 22 engages with the engaging part 4, so that the seat A is seated as shown in FIGS. 1 and 2. B is attached and can be used as a seat.

In addition, when placing a physically handicapped person in a car while seated, both sliders 20 are pulled back using the operating member 23 to release the engagement between the engaging parts 4 and 22, and the seat B
The rear edge side is lifted to allow the protrusion 19 to escape from the recess 3, and then the tip of the support rod 2 and the recess 18 are disengaged and the seat B is carried.

As shown in FIGS. 1 and 2, both ends of the U-shaped seat frame 16 are rotatably attached to the bucket seat 17 via pins 24, and both ends are attached to the rear edge of the seat frame 16. U-shaped tilting rod 2 rotatably mounted
5 is interposed between the two rail plates 26 on the front and back of the back surface of the bucket seat 17, and the recesses 27 are provided with a required number of steps on the top and bottom of the inner surface of one of the rail plates 26.
By fitting and latching the upper end of the tilting rod 25 at the required position, the inclination of the bucket seat 17 can be changed freely.

Further, the engaging portion 22 is formed by cutting out the end surface of the slider 20.

Furthermore, the spring 21 is incorporated into the slider 20 so that one end thereof is attached to the end wall of the slider 20, and the spring 21 is attached to the seat frame body 1.
The other end is brought into contact with a stud 28 which is passed through 6.

The protrusion 19 is formed by passing a stud through the seat frame body 16 and fitting a cylindrical body to the outside of one end of the stud.

Note that both sliders 20 may be pulled back by hand without being connected by the operating section.

In the figure, 29 is a long hole provided in the slider 20, and the stud 28 is passed through this long hole 29 to determine the stop position of the slider 20. 30 is a pillow;
is a pillar member 32 that is suspended from the pillow 30 to a cylindrical portion 31 provided at the upper part of the back surface of the bucket seat 17.
The height can be freely adjusted by inserting the bolt 33 into the cylindrical part 31 and screwing in the bolt 33.

〔effect〕

As described above, according to the chair according to this invention, a physically disabled person can be placed in a car with the seat removed from the seat, and the physically disabled person can be removed from the car with the seat and the seat can be attached to the seat. Therefore, there is no need to hold a physically disabled person when getting on or off the train.

Therefore, the posture of the physically handicapped person is stable and does not cause fear, and the chair can also be used as a seat indoors.

When the seat is placed on the seat, the sliding of the seat due to the upward slope of the support rod is stopped by the engagement between the protrusion and the recess, and the rearward reversal of the seat is prevented by the engagement between the tip of the support rod and the recess. It can be stopped by fitting.

Furthermore, the seat can be fixed to the seat by engaging the engaging portion of the slider and the engaging portion of the support rod.
