Description

Wheelchair slope

The present invention relates to a wheelchair slope used across a step.

In a building such as a building or a public facility, a step generated between objects may be an obstacle to a wheelchair user. This level difference occurs at, for example, a staircase in a building or the boundary between a roadway and a sidewalk. Some of these steps have wheelchair ramps that are provided alongside the steps, but not all steps have wheelchair ramps.
Even if the level difference is not a problem for ordinary people, a wheelchair user may find it difficult to get over the level difference.

In order to solve this problem, for example, a portable slope (wheelchair slope) as shown in Patent Document 1 is known so that a wheelchair user can easily pass a wheelchair at the step. .
The portable slope has two plate members (main body portions) connected at the hinge portion, and one side surface of each plate member is provided on a side opposite to the side connected at the hinge portion. An annulus prevention wall (wall part) is provided.

The anti-derailing wall has a height of 15 to 30 mm, a thickness of 8 to 15 mm, and a pressure withstand pressure that can withstand a maximum of 1 cm ² on one side surface of 2941995 to 3922660 N / m ^2. Is set to Furthermore, the surface of the core material made of rigid foamed polyurethane is set with a mold in which carbon fibers and / or glass fibers are wound, and at least one selected from the group consisting of polyethylene, polyester and vinyl ester The resin is poured into the mold, and the plate material and the anti-wheel removal wall are formed integrally.

The upper surface of the alerting portion 10A is formed in a planar shape and is parallel to the upper surface 6A of the first main body portion 7A. The alerting portion 10A is connected to the wall portion 9A side of the wall portion 8A and is formed over a length substantially equal to the wall portion 8A. 11 A of alerting parts are connected to the wall part 8A side of the wall part 9A similarly to the alerting part 10A, and are formed over the length substantially equal to the wall part 9A.
In the alerting portions 10A and 11A, the height H2 protruding from the upper surface 6A of the first main body portion 7A is preferably 3 mm or more and 15 mm or less, and more preferably 3 mm or more and 10 mm or less. Further, the width W2 is preferably 10 mm or greater and 50 mm or less, and more preferably 15 mm or greater and 30 mm or less.
In this way, the alerting portions 10A and 11A protrude from the upper surface 6A and are provided on the upper surface 6A side from the top portions 21A and 22A, which are the most spaced (protruded) portions from the upper surface 6A of the walls 8A and 9A. .

Note that the alerting portions 10A and 11A have a predetermined length in the spanning direction D from the one end portion 17A and a predetermined length in the spanning direction D from the other end portion 19A for the purpose of alerting the user. The length of may not be arranged. This predetermined length is, for example, 100 mm or less.

In the present embodiment, a non-slip portion (not shown) is provided on the upper surface 6A and on the upper surface of the alerting portions 10A and 11A (the anti-slip portion is provided on the upper surface of the alerting portions 10A and 11A). Part may not be provided). The non-slip portion is formed by sandblasting. For example, sand with a diameter of 1 mm or less (most of the diameter is about 100 to 500 μm) is coated with adhesive paint on the upper surface 6A and above the alert portions 10A and 11A. It is formed by spraying on the surface and fixing. In other words, the anti-slip portion has a fine step with an unevenness difference of about 1 mm.
Thus, in this embodiment, the height from the upper surface 6A of the first main body portion 7A to the upper surface of the alerting portions 10A and 11A is 3 mm or more, and the height from the upper surface 6A to the upper portion of the anti-slip portion. Is about 1 mm. For this reason, the step of 3 mm or more in the alerting portions 10A and 11A is three times or more larger than the step of about 1 mm on the upper surface 6A, and the wheelchair user can distinguish and recognize both steps.

As in this embodiment, when the upper surface 6A of the first main body portion 7A has irregularities, attention should be paid to the irregularities on the upper surface 6A in order to allow the wheelchair user to recognize the alerting portion with certainty. It is preferable that the height H2 at which the arousing part protrudes is 3 to 150 times.

As described above, the first main body portion 7A, the wall portions 8A and 9A, and the alerting portions 10A and 11A are integrally formed, and the cross section of the first main body portion 7A is as shown in FIGS. It is configured.
That is, the first main body portion 7A includes a plate-like core material 23A made of a foam material such as urethane resin or vinyl chloride resin, and a first layer 25A having carbon fibers 24A provided on the upper and lower surfaces of the core material 23A. A second layer 28A having glass or carbon fibers 26A and 27A provided on the upper surface of the first layer 25A disposed above and the lower surface of the first layer 25A disposed below; the first layer 25A and the second layer 25A; It is comprised with the thermosetting resin not shown in which the layer 28A was impregnated.

In the first layer 25A, the carbon fibers 24A are arranged in parallel to the spanning direction D. One fiber 26A constituting the second layer 28A is arranged so as to be parallel to the spanning direction D, and the other fiber 27A is a direction that is not parallel to the spanning direction D and is parallel to the fiber 26A. Are arranged so as to be substantially orthogonal. The thermosetting resin is composed of at least one resin selected from the group of unsaturated polyester resin, vinyl ester resin, and epoxy resin.
The first main body portion 7A, the wall portions 8A and 9A, and the alert portions 10A and 11A have the core material 23A, the first layer 25A, and the second layer 28A arranged in a mold, and a thermosetting resin. It is integrally formed of fiber reinforced plastic formed by impregnation. For this reason, the wall portions 8A and 9A and the attention drawing portions 10A and 11A are mainly formed of the fibers 26A and 27A of the second layer 28A and the thermosetting resin.

As shown in FIG. 1, two hook-and- loop fasteners 12 and 13 are disposed at both ends of the first slope 2 in the spanning direction D with a space therebetween. The hook-and- loop fasteners 12 and 13 are formed in a tape shape with a flexible material, and one end portions of the hook-and- loop fasteners 12 and 13 are connected to the lower surface of the first main body portion 7A, and the lower surface of the other end portion is not attached to the lower surface. The illustrated connecting surface is provided.

The second slope 3 includes a second main body portion (main body portion) 7B, wall portions 8B and 9B, alerting portions 10B and 11B, and a handle 14B (not shown) provided on the outer side surface of the wall portion 9B. ).
The hook-and- loop fasteners 30 and 31 are arranged at intervals at positions corresponding to the hook-and- loop fasteners 12 and 13 at both ends of the second slope 3 in the spanning direction D.
The hook-and- loop fasteners 30 and 31 are formed in a tape shape with a flexible material, one end of the hook-and- loop fasteners 30 and 31 is connected to the lower surface of the second body portion 7B, and the upper surface of the other end is A connecting surface (not shown) that can be attached to and detached from the connecting surface of the fasteners 12 and 13 is provided.
When the hook-and-loop fastener 12 and the hook-and-loop fastener 30, the hook-and-loop fastener 13 and the hook-and-loop fastener 31 are connected, and the hook-and- loop fasteners 12, 13, 30, and 31 are stretched in a direction orthogonal to the spanning direction D, the first main body portion. The distance between the upper surface 6A of 7A and the upper surface 6B of the second body portion 7B in the direction perpendicular to the spanning direction D is set to be substantially equal to the distance between the left and right wheels of a general wheelchair having four wheels. Has been.

Next, the usage method of the wheelchair slope 1 comprised as mentioned above is demonstrated.
The user presses the connecting surface of the hook-and-loop fastener 12 and the connecting surface of the hook-and-loop fastener 30 and the connecting surface of the hook-and-loop fastener 13 and the connecting surface of the hook-and-loop fastener 31 to each other, whereby the first slope 2 and the second slope 3 are pressed. And Then, the first slope 2 and the second slope 3 are spanned over the step L in a state where the hook-and- loop fasteners 12, 13, 30 and 31 are stretched in a direction orthogonal to the spanning direction D.
Next, the wheel provided on one side of the wheels provided on the left and right sides of the wheelchair is placed on the upper surface 6A of the first body portion 7A, and the wheel provided on the other side is placed on the second body portion 7B. The wheelchair is placed on the upper surface 6B and passed over the first slope 2 and the second slope 3.

When the wheelchair slope 1 according to the present embodiment is used, the user first deforms the hook-and- loop fasteners 12, 13, 30, and 31 so that the positions of the handle 14A and the handle 14B approach each other. The slope 2 and the second slope 3 are overlapped. The wheelchair slope 1 is carried with the handles 14A and 14B.

As described above, according to the wheelchair slope 1 of the present embodiment, the user spans the first slope 2 and the second slope 3 over the step L. And the wheel provided on one side of the wheelchair between the pair of wall portions 8A and 9A on the upper surface 6A of the first main body portion 7A is on the upper surface 6B of the second main body portion 7B. A wheel provided on the other side is disposed between the pair of wall portions 8B and 9B, and the wheelchair is moved in the crossing direction D.

When the moving direction of the wheelchair deviates from the crossing direction D, the wheelchair wheel comes off from the first slope 2 by the wheels 8A and 9A projecting from the upper surface 6A of the first main body 7A. Is prevented. At this time, on the upper surface 6A of the first main body portion 7A, between the pair of wall portions 8A and 9A, alerting portions 10A and 11A connected to the wall portions 8A and 9A are provided. For this reason, when the wheel of the wheelchair is not in contact with the walls 8A and 9A and is within a predetermined range from the walls 8A and 9A, the user can move the wheel of the wheelchair to the first main body 7A. By recognizing the force received when riding on the alerting portions 10A, 11A protruding from the upper surface 6A, it is recognized that the wheelchair wheel has reached the alerting portions 10A, 11A.
Since the alerting portions 10A and 11A are provided on the upper surface 6A side of the first main body portion 7A with respect to the top portions 21A and 22A of the wall portions 8A and 9A, the wheelchair is moved to the first main body portion 7A by the wall portions 8A and 9A. The user can correct the wheelchair trajectory by preventing the wheelchair wheel from approaching the wall 8A, 9A by the alerting portions 10A, 11A. It is possible to improve the safety when the wheelchair is running.

Moreover, since the 1st main-body part 7A, wall part 8A, 9A, and alerting part 10A, 11A are integrally comprised with the fiber reinforced plastic, while increasing the intensity | strength as the whole wheelchair slope 1, it is lightweight. Can be.
And since alerting part 10A, 11A is arrange | positioned continuing to wall part 8A, 9A, the width | variety of the center part of the 1st main-body part 7A through which the wheel of a wheelchair passes can be ensured widely.

In the present embodiment, in the alert portions 10A and 11A, the width W2 is set to 10 mm to 50 mm, and the height H2 is set to 3 mm to 15 mm.
If the width W2 of the alerting portions 10A and 11A is less than 10 mm, when the wheel of the wheelchair rides on the alerting portions 10A and 11A, the wheel comes into contact with the wall portions 8A and 9A and the wheelchair stops suddenly. This cannot be prevented. When the width W2 exceeds 50 mm, the effect of alerting the user is not improved, but the width of the upper surface 6A of the first main body portion 7A is narrow when the width of the first slope 2 is constant. turn into.
In addition, if the height H2 at which the alerting portions 10A and 11A protrude is less than 3 mm, it is difficult for the user to recognize the presence or absence of the alerting portions 10A and 11A through the wheelchair, and if the height H2 exceeds 15 mm, Similar to when the wheelchair wheel comes into contact with the walls 8A and 9A, the wheelchair may suddenly stop or change direction.

Further, a tapered portion 18A is provided at one end portion 17A of the first main body portion 7A, and a groove portion 20A is formed at the other end portion 19A. Therefore, the first slope 2 is arranged so that the tapered portion 18A of the first body portion 7A is on the lower step L1 side and the groove 20A is on the step upper L2 side. Thus, the taper portion 18A can suppress a difference in level between the lower step portion L1 and the one end portion 17A of the first main body portion 7A. Furthermore, the other end portion 19A of the first main body portion 7A can be reliably engaged with the stepped upper portion L2 by the groove portion 20A.

And as a main-body part, the 1st main-body part 7A and the 2nd main-body part 7B are provided. For this reason, generally, the wheel provided on one side among the wheels provided on the left and right of the wheelchair having four wheels is the first body portion 7A, and the wheel provided on the other side is the second body. By passing through the portion 7B, the width in the direction orthogonal to the spanning direction D between the first main body portion 7A and the second main body portion 7B can be reduced. Therefore, the wheelchair slope 1 can be reduced in weight as a whole.
Moreover, since the surface fastener 12, 13, 30, 31 which connects the 1st main-body part 7A and the 2nd main-body part 7B so that attachment or detachment is possible is provided, 7A of 1st main-body parts and the 2nd main-body part 7B are provided. And can be positioned.
Furthermore, since the hook-and- loop fasteners 12 and 13 and the hook-and- loop fasteners 30 and 31 are arranged at intervals in the spanning direction D, the first slope 2 and the second slope 3 can be positioned more reliably. Can do.

And since the 1st layer 25A which has arrange | positioned the carbon fiber 24A, and the 2nd layer 28A which has arrange | positioned the fiber 26A are used for the 1st main-body part 7A, the bending rigidity of the 1st main-body part 7A is improved. Can be made.

In the present embodiment, the two hook-and- loop fasteners 12 and 13 are connected to the first slope 2 at intervals in the spanning direction D. However, the number of hook-and-loop fasteners connected to the first slope 2 may be any number as long as it is one or more.
Further, the connecting member is not a flexible hook-and-loop fastener but may be, for example, a rod-like member having a certain rigidity and having connecting mechanisms such as hinges at both ends.

Also, as shown in FIGS. 6A and 6B, elastic members 41A and 42A are attached to the lower surface of at least one end of the first main body portion 7A in the spanning direction D. You may comprise.
That is, in FIG. 6A, a recessed portion is formed on the lower surface of one end portion 17A of the first body portion 7A, and an elastic member 41A formed of rubber or the like is fixed to the portion with an adhesive or the like. ing.
The lower surface of the elastic member 41A may be formed so as to have a wave shape when viewed from the side.
In FIG. 6B, a recessed portion is formed on the lower surface of the other end portion 19A of the first main body portion 7A, and an elastic member 42A formed of rubber or the like is fixed to the portion. The lower surface of the elastic member 42 </ b> A may be formed to have a wave shape in a side view.
By forming the lower surfaces of the elastic member 41A and the elastic member 42A into a corrugated shape, the grip force with which the first slope 2 is locked to the step L can be increased.

Further, as shown in FIGS. 7 and 8, the glass is disposed between the core member 23 </ b> A and the first layer 25 </ b> A constituting the first main body portion 7 </ b> A so that the fiber direction is random (random).
