Description

  The present invention relates to an improvement of a step-eliminating slope which is installed at a step portion of a building such as a doorway of a room to eliminate the step and to easily get over the step portion with a wheelchair or a walker for nursing care.

  A wedge-shaped member called a step-elimination slope is installed at the step of the building, such as the entrance of the room, to eliminate the step, making it easy to get over the step with a wheelchair or a walker for nursing care (hereinafter referred to as "wheelchair etc."). It is generally done. As an example of such a step eliminating slope, for example, a slope shown in Patent Document 1 is known.

  This conventional step eliminating slope is a rubber member formed in a substantially wedge shape, and runs on a running surface that is gently inclined downward from the upper end of the rear surface arranged adjacent to the step to the front end in contact with the floor surface. When a wheelchair or the like passes, a step can be easily overcome.

Registered Utility Model No. 3177598 (FIG. 1)

  In many cases, the height of the step is relatively low at 0.5 to 5.0 cm, and therefore, the conventional slope for eliminating the step is mainly manufactured to have a height of 0.5 to 5.0 cm according to the step. Was.

  On the other hand, not only such a low step but also a relatively high step of, for example, 10 to 15 cm exist in the building, and voices of users who are waiting for the appearance of a large stepping slope capable of coping with such a high step have been heard. There were many.

  However, if such a large-sized slope eliminating slope is manufactured by using a relatively heavy rubber like a conventional slope eliminating slope, there is a problem that the weight becomes so large that it cannot be carried and is not suitable for practical use.

  Of course, if a lightweight and highly rigid material such as FRP is used, the above-mentioned problem can be solved. However, due to its high rigidity, the following problem newly arises.

  In other words, the floor on which the step-reducing slope is arranged actually has some bending and irregularities even though it looks flat. For this reason, when a large stepping slope formed by using a material having high rigidity such as FRP is installed at a stepped portion, a slight gap is generated between a bent or uneven floor surface and the stepping slope, and a wheelchair is provided. This causes rattling when going over steps.

  The present invention has been made in view of such conventional problems, and provides a step-reducing slope that is lightweight even if it is made larger, and that can prevent rattling even when it is installed on a floor with flexure or unevenness. Is to do.

The invention described in claim 1 is described as follows. "A substantially wedge-shaped slope main body 12 made of a material having both lightness and rigidity, which is disposed at a corner portion Y of a step X of a building, and adheres to a running surface 12b of the slope main body 12. The step-eliminating slope 10 having the running surface non-slip sheet 16 and the bottom surface non-slip sheet 20 adhered to the bottom surface 12e of the slope body 12,
On the back surface 12a of the slope main body 12, which is in contact with the vertical surface X1 of the corner portion Y of the step X, adjuster mounting recesses 22 are formed on the left and right sides of the bottom surface 12e, and each adjuster mounting recess is formed. 22, the adjuster 14 is attached so as to be able to protrude and retract. "

  The invention described in claim 2 is characterized in that a recess 24 for a handle is formed on the side surfaces 12 c and 12 d of the slope main body 12.

  The invention described in claim 3 is characterized in that the side slip prevention sheet 18 is adhered to the side faces 12 c and 12 d of the slope main body 12.

  The invention described in claim 4 is characterized in that "diamond pattern unevenness 18 is formed on the surface of each anti-slip sheet 16, 18, 20".

  According to the present invention, since the slope main body is formed of a material having both lightness and rigidity, it is possible to obtain a lightweight and practical step-eliminating slope even if the slope main body is enlarged.

  In addition, since the adjuster is provided on the back surface that is in contact with the vertical surface of the corner part of the step in the slope main body so that it can protrude and retract, there is slight bending or unevenness on the floor surface, between the slope and the slope to eliminate the step Even if a slight gap is generated, rattling due to the gap can be prevented by projecting and retracting the adjuster.

FIG. 3 is a perspective view showing a step-reducing slope according to the present invention. FIG. 2 is a sectional view taken along line A-A ′ in FIG. 1. FIG. 2 is an exploded perspective view of a step-reducing slope according to the present invention. It is a figure showing a use state. It is a use explanatory view of an adjuster.

  Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a slope eliminating slope 10 according to the present invention, FIG. 2 is a sectional view taken along the line A-A 'in FIG. 1, and FIG. 3 is an exploded perspective view of the slope eliminating slope 10.

  As shown in these figures, the slope eliminating slope 10 of the present invention is roughly constituted by a slope main body 12, an adjuster 14, a non-slip sheet 16 for a running surface, a non-slip sheet 18 for a side surface, and a non-slip sheet 20 for a bottom surface. I have.

  The slope main body 12 includes a back surface 12a in contact with a vertical surface X1 (see FIG. 5) of a corner portion Y of the step X, a running surface 12b inclined downward from an upper edge of the back surface 12a toward a front end, left and right side surfaces 12c and 12d, and a floor. It is a substantially wedge-shaped member having a bottom surface 12e in contact with the surface C, and is formed in a substantially right triangle when viewed from the side surface 12c (or 12d) side. In the present embodiment, the central portion of the bottom surface 12e of the slope main body 12 is carved for weight reduction.

  The height H (FIG. 2) of the slope body 12 is set to be equal to or slightly lower than the height of the step X, and is set to 15 cm in the present embodiment. The width of the slope main body 12 is set to a width (for example, in a range of 70 to 100 cm) through which a wheelchair or the like can easily pass, and is set to 70 cm in the present embodiment.

  In addition, the slope θ of the slope body 12 (the angle formed by the running surface 12b and the bottom surface 12e) is set to an angle (for example, in a range of 10 to 15 degrees) at which the vehicle can easily get over in a wheelchair or the like. Set to degree.

  As the material of the slope body 12, it is preferable to use fiber reinforced plastic (FRP), which is a material having both lightness and rigidity, from the viewpoint of reducing the weight of the large-sized step-eliminating slope 10, and in the present embodiment, it is relatively preferable. Inexpensive glass fiber reinforced plastic (GFRP) is employed.

  On the rear surface 12a of the slope main body 12, adjuster mounting recesses 22 that open to the bottom surface 12e side are formed on both left and right sides thereof, and a screw hole 22a is formed on the ceiling surface of each adjuster mounting recess 22. I have. A leg 14b of the adjuster 14, which will be described later, is screwed into the screw hole 22a.

  The adjuster 14 is provided to prevent rattling between the floor surface C and the step eliminating slope 10 and has a base 14a, legs 14b, and a fixing nut 14c.

  The base 14a is a resin-made disc-shaped member, and a leg 14b is provided upright at a central portion thereof. The leg 14b is formed by a cut bolt having an external thread engraved on its outer surface, and the leg 14b is screwed into the screw hole 22a of the adjuster mounting recess 22 described above. A fixing nut 14c is screwed on the outer surface of the leg 14b.

  A running surface anti-slip sheet 16 is attached to the entire running surface 12b of the slope main body 12, and a bottom surface anti-slip sheet 20 is attached to the front end of the bottom surface 12e.

  Further, a recess 24 for a handle opening to the side of the bottom surface 12e is formed on each of the left and right side surfaces 12c and 12d of the slope main body 12, and a side anti-slip is provided so as to sandwich the recess 24 for the handle. The sheet 18 is stuck.

  In addition, the irregularities 26 of the diamond pattern are formed on the entire surface of each of the above three types of non-slip sheets (the non-slip sheet 16 for the running surface, the non-slip sheet 20 for the bottom surface, and the non-slip sheet 18 for the side surface). (See the circle in FIG. 3).

  When using the step eliminating slope 10 configured as described above, as shown in FIG. 4, the rear surface 12 a of the slope main body 12 is pressed against the vertical surface X 1 of the step X, and the step eliminating slope 10 is At the corner portion Y of.

  A gap S may be generated between the slope main body 12 and the floor surface C because the floor surface C is partially bent (see FIG. 5). When the slope main body is made of a flexible material such as rubber like a conventional slope for eliminating a step, the gap S is filled by bending the slope main body itself and following the shape of the floor surface C. When the slope main body 12 is formed of a material having high rigidity (FRP), such as the slope eliminating slope 10 of the embodiment, since the slope main body 12 does not bend, the gap between the floor surface C and the bottom surface 12e of the slope main body 12 is formed. Is maintained.

  Therefore, in the step eliminating slope 10 of the present embodiment, the rattling due to the gap S is eliminated by adjusting the height of the adjuster 14.

  Specifically, the base 14a of the adjuster 14 is rotated while keeping the height of the slope main body 12 equal to the height of the step X, and the adjuster 14 is made to protrude and retract from the adjuster mounting recess 22. Then, when the base 14a comes into contact with the floor surface C, the rotation of the base 14a is stopped and the fixing nut 14c is tightened. When the height adjustment is completed as described above, the step eliminating slope 10 is arranged at the corner Y of the step X by pressing the back surface 12a of the slope main body 12 against the vertical surface X1 of the step X. The installation of 10 is completed.

  According to the slope eliminating slope 10 of the present embodiment, since the slope main body 12 is formed of a material (FRP) having both lightness and rigidity, even if the slope main body 12 is enlarged, it is lightweight and practical. It can be set to 10.

  Moreover, since the adjuster 14 is provided on the back surface 12a of the slope main body 12 which is in contact with the vertical surface X1 of the corner portion Y of the step X, the floor surface C has flexures and irregularities. Even if a slight gap S is formed between the slope body 12 and the slope main body 12, the gap S can be eliminated by adjusting the height of the adjuster 14 to prevent rattling.

  In addition, the three types of anti-slip sheets used for the step-reducing slope 10, namely, the anti-slip sheet 16 for the running surface, the anti-slip sheet 20 for the bottom surface, and the anti-slip sheet 18 for the side surface, respectively have diamond patterns. Since the unevenness 26 is formed over the entire surface, a high anti-slip effect can be obtained.

  Further, since the recesses 24 for the handle are provided on the side surfaces 12c and 12d of the slope main body 12, it is possible to obtain an effect that the carrying work can be easily performed by hanging the recess 24 for the handle. it can.
