Description

  The present invention relates to a temporary slope device having a spiral plate-like passage.

  As a temporary slope device spanned over the stepped portion, for example, as shown in Patent Document 1, it is generally configured by a straight plate material, and a wheelchair or the like travels linearly on the slope. there were.

  However, in such a straight plate-like slope device, it is necessary to secure a relatively wide space outside the both ends of the slope device as a space for getting on and off the slope, and in a place where such a space cannot be secured, Installation itself becomes difficult.

Under such circumstances, for example, Patent Documents 2 and 3 propose slopes in which the passage direction is set to an orthogonal direction. That is, both Patent Document 2 and Patent Document 3 both allow a wheelchair to enter and exit from a building window, and provide a landing on the outside of the window, and provide this landing along the wall of the building. In this way, the space on the near side of the window can be narrowed.

Japanese Patent Laid-Open No. 10-292585 Japanese Patent Laid-Open No. 10-292585 JP 2007-138480 A JP 2009-2136 A

  However, in the slope devices shown in these Patent Documents 2 and 3, since a landing is provided and a straight plate-like slope is connected to one side of the landing, when a wheelchair is moved through the slope device, It is necessary to change the direction of the wheelchair at the landing, and it is necessary to set the size of the landing space so that the direction of the wheelchair can be changed. In addition, the operation of the wheelchair is complicated, especially when the user of the wheelchair is a physically handicapped person such as a disabled person or an elderly person, and the person himself / herself performs a driving operation without relying on an assistant. In that case, there was a problem that wheelchair movement itself was extremely difficult.

  In view of such circumstances, it is conceivable that the slope device is formed in a spiral plate shape and can be continuously moved without changing the direction of the wheelchair while traveling (see, for example, Patent Document 4). According to the spiral plate structure, depending on the installation conditions of the slope device, it may be difficult to get on and off the slope device. This will be briefly described with reference to FIG.

  FIG. 12A is a plan view showing a state in which a slope device Z configured as a spiral plate that is curved substantially at a right angle in plan view is bridged between the high level surface Ga and the low level surface Gb of the stepped portion. It is. FIG. 12B is a front view showing the inner peripheral edge Z1 and the outer peripheral edge Z2 of the slope device Z shown in FIG. In the spanning state of the slope device Z, the high-order end Za and the low-order end Zb of the slope device Z are both in contact with the high-order surface Ga and the low-order surface Gb over the entire width. That is, in the slope device Z, when the step height between the high-order surface Ga and the low-order surface Gb is “h”, the high-order end Za and the low-order end Zb of the slope device Z are both high-order surface Ga and This is set so as to be in contact with the lower surface Gb, and this state is referred to as a “reference state” (the same applies to the following description).

  On the other hand, FIG. 12 (c) is a front view showing the slope device Z in a developed state when the slope device Z is bridged over a step portion having a step height “h1” (h1> h). Here, as an example of the installation state, a state in which the high-order end Za of the slope device Z is in contact with the high-order surface Ga with its full width is shown. In this installed state, since the step height “h1” is higher than the step height “h” in the reference state, the lower end Zb of the slope device Z is one end in the width direction of the lower end Zb (the end of the outer peripheral edge Z2). Are in point contact, and the other portions are lifted upward from the lower surface Gb (one-contact state). Therefore, it is difficult to get on and off the wheelchair from the lower end Zb side of the slope device Z.

  On the other hand, FIG. 12D is a front view of the slope device Z developed and illustrated when the slope device Z is bridged over the step portion having the step height “h2” (h2 <h). In this case as well, the high-order end Za of the slope device Z is in contact with the high-order surface Ga with its full width. Then, since the step height “h2” is lower than the step height “h” in the reference state, the lower end Zb of the slope device Z is in point contact with one end in the width direction of the lower end Zb (the end of the inner peripheral edge Z1). However, the other portions are in a state of being lifted upward from the lower surface Gb (one-sided state). Therefore, also in this case, it is difficult to get on and off the wheelchair from the lower end Zb side of the slope device Z.

  It should be noted that the one-side contact state of the slope device Z is contrary to the above, when the lower end Zb of the slope device Z is in contact with the lower surface Gb over the entire width, It occurs on the end Za side. Further, as an intermediate state between the two, it is possible to set both the high-order end Za and the low-order end Zb of the slope device Z so that they are in a single-contact state with respect to the high-order surface Ga and the low-order surface Gb. In this case, the high-order end of the slope device Z is smaller in the vertical direction than the high-order surface Za and the low-order end Zb of the slope device Z with respect to the high-order surface Ga and the low-order surface Gb. It is difficult to get on and off the wheelchair at both Za and the lower end Zb.

  Since the problems as described above exist, even though the idea of the spiral plate-like slope is relatively easy from the description in Patent Document 4, the technology for realizing this as a temporary slope device is Not yet proposed.

  Therefore, the present invention has been made for the purpose of proposing a technique for realizing a spiral plate-like slope device.

  In the first invention of the present application, there is provided a slope device that spans between a high surface and a low surface, and is a spiral that curves in a predetermined height range from one end side to the other end side in the passage direction in a plan view. A plate-shaped slope body, a support means for supporting the slope body in a predetermined posture, and an end slope provided at at least one end of the slope body, and the end slope at the end of the slope body It is characterized by comprising a plurality of single plates arranged in a row in the width direction and capable of relative rotation around a row axis.

  According to a second invention of the present application, in the slope device according to the first invention, the slope main body has a shape that is curved at a substantially right angle in a plan view.

  In 3rd invention of this application, in the slope apparatus which concerns on the said 1st or 2nd invention, the said support means was comprised with the support | pillar which can be height-adjusted by changing the number of use of several connection piece. It is characterized by.

  (A) According to the slope device according to the first invention of the present application, the spiral plate-like slope body that curves in a predetermined height range from one end side to the other end side in the passage direction in plan view, A support means for supporting the slope body in a predetermined posture and an end slope provided at at least one end of the slope body, and the end slope are arranged in a row in the width direction at the end of the slope body. In addition, since it is composed of a plurality of single plates that are relatively rotatable around the arrangement axis, the slope body is in a predetermined posture by the support means in a state where the slope body is bridged between the high level surface and the low level surface. And at least one end of the slope main body and the high or low surface are connected by the end slope.

  In this case, when the one end of the slope body and the high surface or low surface face each other substantially in parallel (that is, the step height between the high surface and the low surface is the height of the slope body in the reference state set initially). Are substantially coincident with each other), the respective single plates of the end slope are set at substantially the same rotational position and are arranged in the width direction of the slope body to form a substantially flat surface. Therefore, it is possible to get on and off the wheelchair on the slope body through the end slope.

  On the other hand, when one end of the slope body and the high-level surface or low-level surface face each other in an inclined manner (that is, the step height between the high-level surface and the low-level surface is different from the initially set height of the slope body in the reference state). Each of the single plates arranged in the width direction of the end slope individually rotate corresponding to the facing distance at the position of each single plate, and the width of the slope body A substantially curved plate surface that is successively continuous with a predetermined twist in the direction is formed. Accordingly, the facing distance between one end of the slope body and the high-level surface or the low-level surface is eliminated by the end slope, and the wheelchair can get on and off the slope body through the end slope.

  That is, according to the slope device of the present invention, if the level difference of the installation location is within a predetermined range, the end of the slope body and the high level surface or low level surface of the level difference portion are always provided regardless of the size of the level difference. It is smoothly connected by the end slope, and it is possible to get on and off the slope body from the higher surface side and the lower surface side. Therefore, the wheelchair can be traveled through the slope body, and it is not necessary to temporarily stop the wheelchair during the travel and to change the direction, so that the wheelchair is continuously and lightly traveled.

  Further, the slope device has a spiral body whose slope body is curved from one end side to the other end side in the passage direction, and in the installation state on the step portion of the slope device, the direction along the step surface. Since it is possible to get on and off the above slope body, for example, it is not necessary to secure a large space on the near side of the step surface as in the case of installing a straight plate slope, and it can be installed in a smaller space, The scope of application of the slope device is expanded, and as a result, the commercial value of the slope device is improved.

  (B) In the second invention of the present application, in addition to the effects described in the above (a), the following specific effects can be obtained. That is, in the present invention, the slope main body has a shape that is curved at a substantially right angle in a plan view, so that the extension width from the step surface of the slope device to the near side can be minimized, and the slope device Installation in a small space is further improved.

  (C) In the third invention of the present application, in addition to the effects described in the above (a) or (b), the following specific effects can be obtained. That is, in the present invention, the support means is constituted by a support column that can be adjusted in height by changing the number of use of the plurality of connecting pieces. Therefore, when the slope device is installed on the step portion, By adjusting the height of the high end and the low end more finely, the relative position in the height direction between the high level surface and the low level surface of the stepped portion can be accurately set to a desired position. The stability in the installed state is ensured, and the safety in use of the slope device is improved.

A: First Embodiment FIGS. 1 to 3 show a slope device 1 according to a first embodiment of the present invention. This slope device 1 is bridged between a high level surface Ga and a low level surface Gb of a stepped portion, and is used for passage of a person or a wheelchair. It comprises an end slope 3 attached to the passage direction both ends 2a, 2b.

  The slope main body 2 has a predetermined height range and the one end 2a in the passage direction in plan view (hereinafter referred to as “high end 2a” corresponding to the embodiment) side to the other end 2b (hereinafter referred to as embodiment). And has a spiral plate-like shape that is curved at a substantially right angle toward the “low end 2b” side, and is formed of a resin foam molded body as shown in FIGS. A main body portion 21 formed by sticking and fixing a reinforcing sheet material 25 made of fiber reinforced plastic to both surfaces of the spiral plate-shaped core member 24, and a high-side end member 22A fixed to the high-end end 2a side of the main-body portion 21 And a lower side end member 22B fixed to the lower end 2b side, and side edge members 23 fitted and fixed to the left and right edges of the main body part 21, respectively.

  As described above, since the one end 2a of the slope main body 2 is the “high end 2a” and the other end 2b is the “low end 2b”, the high side end fixed to both ends of the main body portion 21, respectively. The member 22A and the lower end member 22B correspond to the higher end 2a and the lower end 2b of the slope body 2, respectively.

  Both the high-side end member 22A and the low-side end member 22B are made of an aluminum extruded material, and as shown in FIGS. 5 and 6, the outer end surface thereof has a width direction of the slope main body 2. A fitting recess 26 and an abutting portion 27 are provided in a state of being appropriately separated in the height direction of the end members 22A and 22B. And each single plate 4 which comprises the edge part slope 3 described below is attached to the said fitting groove 26 part of each of these end members 22A and 22B.

  The end slope 3 is attached to the high-end end member 22A located at the high-end end 2a of the slope main body 2 and the low-end end member 22B located at the low-end 2b, respectively. As shown in FIGS. 5 and 6, the vehicle is configured to include five single plates 4.

  The single plate 4 is integrally formed of, for example, an aluminum extruded material, and has a substantially wedge-like shape whose height gradually decreases from the base end side toward the tip end side, as shown in FIGS. 5 and 6. It has a cross-sectional shape, and a fitting protrusion 41 and a contact portion 42 extending in the width direction are provided on the end surface on the base end side thereof so as to be appropriately separated in the height direction of the single plate 4. It has been. And this single plate 4 is made to fit the fitting convex line 41 to the fitting concave line 26 provided on the high-order side end member 22A of the slope body 2 from the axial direction. It is connected to the end member 22A.

  In this way, the single plates 4 are sequentially connected to the higher-side end member 22A side, so that a plurality of single plates 4 are arranged in the width direction of the slope body 2, thereby constituting the end slope 3 Is done. Note that the end slope 3 is attached to the lower end member 22B side of the slope body 2 in the same manner as described above. In this embodiment, the end slope 3 is composed of five single plates 4. However, the present invention is not limited to such a configuration, and the single plate 4 constituting the end slope 3 is not limited thereto. The number can be arbitrarily increased or decreased.

  Each single plate 4 of the end slope 3 can be rotated relative to each other about the row axis L, and the maximum rotation upward is provided on the single plate 4 as shown in FIG. The contact portion 42 is regulated by contacting the contact portion 27 on the high-side end member 22A side (this position is referred to as an upward movement restricting position). In this restricted state, the contact point between the contact portion 27 on the high-side end member 22A side and the contact portion 42 on the single plate 4 side, and the fitting groove 26 on the high-side end member 22A side. And the fitting point between the fitting protrusions 41 on the single plate 4 side are appropriately separated in the thickness direction of the single plate 4 so that the single plate 4 is rotated further upward. Can withstand the load.

  On the other hand, the maximum downward rotation of the single plate 4 is restricted by the convex portion 28 provided on the high-side end member 22A side coming into contact with the concave portion 44 provided on the single plate 4 side (this The position is called the downward movement restriction position). Therefore, the single plate 4 can be rotated between the upper movement restriction position and the lower movement restriction position with the fitting portion as a rotation center. The rotational positions of the high-end side end member 22A and the low-end side end member 22B automatically correspond to the inclined state in the width direction (that is, the self-weight rotation force around the fitting portion of the single plate 4 and the single plate). 4 and the high-order surface Ga or the low-order surface Gb).

  Here, the spiral plate-like shape setting of the slope body 2 will be described with reference to FIG. As described above, the slope body 2 has a spiral plate-like shape that is curved at a substantially right angle from the high end 2a side to the low end 2b side in a predetermined height range and in a plan view. The “predetermined height” mentioned here is the height in the “reference state” already described. In this embodiment, the height “h” of the step surface Gc is assumed as shown in FIG. Yes.

  In the above description using FIG. 12, the state in which both the high-end end 2a and the low-end end 2b of the slope body 2 are in contact with the high-order surface Ga and the low-order surface Gb of the stepped portion with their full width is referred to as “reference state In this embodiment, as will be described later, the lower end 2b of the slope body 2 is set parallel to the lower surface Gb, and an end slope 3 described later is connected to the lower end 2b. For the convenience of explanation, the height “ha” from the lower surface Gb to the higher surface Ga where the tip of the end slope 3 contacts over the entire width is defined as the “predetermined height”. Therefore, in the “reference state” shown in FIG. 4, the end slope 3 attached to the lower end 2b of the slope body 2 is in contact with the lower face Gb at the tip end portion of the end slope 3 while the entire width of the end slope 3 is increased. The high end 2a of 2 is parallel to the high level surface Ga at the same height as the high level surface Ga, and the end slope 3 attached to the high level end 2a has the end portion over its entire width. The slope 3 comes into contact with the higher surface Ga.

  Thus, since the spiral plate-like shape of the slope body 2 is set, when the slope device 1 is installed in a stepped portion having a height different from the reference state as in this embodiment, the above “ As in the case of the “reference state”, both the high end 2a and the low end 2b of the slope body 2 are not parallel to both the high level surface Ga and the low level surface Gb of the stepped portion. It will be a hit state. As described above, in this “one-sided state”, there is a substantially wedge-shaped gap between the high end 2a or low end 2b of the slope body 2 and the high surface Ga or low surface Gb. It is.

  It is the end slope 3 that allows the wheelchair to get on and off the slope body 2 from the high-order surface Ga or the low-order surface Gb by eliminating the gap caused by such a “one-sided state”. In the slope device 1 of the present invention, the end slope 3 is the most important element. Hereinafter, based on this point, the installation of the slope device 1 and the operation and effects thereof will be described.

  1 to 3 show an installation state in which the slope device 1 according to the present invention is bridged over a stepped portion. Here, as shown in FIG. 2 and FIG. 3, the step portion where the slope device 1 is installed has a step height “hb”, which is higher than the step height “ha” in the reference state shown in FIG. 4. Is also high. Therefore, when the slope device 1 is installed between the high level surface Ga and the low level surface Gb of the stepped portion, a "one-sided state" occurs. In this embodiment, in particular, as an example of the installation state, The lower end 2b side of the slope body 2 is set parallel to the lower surface Gb so that a “one-sided state” is generated only on the higher end 2a side of the slope body 2. Therefore, at the high-order end 2a of the slope body 2, one end in the width direction (end on the inner peripheral side) is the same height as the high-order surface Ga, and the outer peripheral side from the end is from the high-order surface Ga. It will be in the state inclined so that it might gradually space apart upwards.

  In this embodiment, the high-order end 2a of the slope body 2 is not placed directly on the high-order surface Ga, but is positioned immediately before the front edge of the high-order surface Ga. It is necessary to hold the slope body 2 in this posture, and for this purpose, a plurality of support columns 5 are provided on the lower surface side of the slope body 2. That is, in this embodiment, the column 5 is connected to the left and right sides of the high-end end member 22A at the high-end end 2a of the slope body 2, the left and right sides of the low-end end member 22B at the low end 2b, and the inner They are arranged at a total of six positions including a circumferential intermediate position of the peripheral edge and a circumferential intermediate position of the outer peripheral edge. In this case, among these six struts 5, the pair of struts 5 provided on the left and right sides of the lower-side end member 22B have the same height, but the struts 5 arranged at positions other than these are respectively The height of the column 5 differs depending on the arrangement position.

  As described above, since the height of the support column 5 needs to be adjusted according to the arrangement position, in this embodiment, as shown in FIG. 7, a bolt 52 is provided at one end in the axial direction, and the other end is provided at the other end. An appropriate number of short shaft-shaped column pieces 51 having bolt holes 53 are connected, a grounding base 54 is attached to the lower end thereof, and a receiving member 55 is attached to the upper end thereof. The column 5 having a required length is obtained by selecting the above. Therefore, when the slope device 1 is installed in the step portion, the height of the high-order end of the slope body 2 is adjusted more finely so that the relative position in the height direction of the step portion with the high-order surface Ga is accurately set to a desired position. Therefore, the stability in the installed state of the slope device 1 is ensured, and as a result, the safety in use of the slope device 1 is improved.

  As described above, the slope main body 2 is supported by the six support columns 5 and fixed and held at a predetermined position in a predetermined position. In this state, the end slopes 3 are connected to the high end 2a and the low end 2b of the slope body 2, respectively. The state where the end slope 3 is connected is the state shown in FIGS. In the installed state of the slope device 1, the high end 2a side is inclined with respect to the high level surface Ga. In this state, the high level end 2a is interposed between the high level end 2a and the high level surface Ga. A gap that gradually increases and changes in the width direction is generated, and it is difficult to run the wheelchair in this portion.

  Therefore, in this embodiment, the end slope 3 connected to the higher end 2a side of the slope body 2 is provided with a plurality of five single plates 4 that are rotatable in the thickness direction (vertical direction). The high end 2a is arranged in the width direction. According to such a configuration, each of the single plates 4 rotates according to the size of the gap at a position where they correspond to each other (that is, as the gap is larger, the descending inclination angle from the higher end 2a is larger). It is constructed between the high level end 2a of the slope main body 2 and the high level surface Ga in a state where the gap is eliminated (see FIGS. 2 and 3).

  As a result, the end slope 3 composed of the single plates 4 arranged in the width direction of the high end 2a with different inclination angles between the high end 2a of the slope body 2 and the high surface Ga. Are connected continuously. Further, on the lower end 2b side of the slope body 2, the end slope 3 connected to the slope body 2 is formed into a flat plate shape by arranging the single plates 4 at the same rotational position. Accordingly, the wheelchair gets on and off between the slope body 2 and the higher surface Ga through the end slope 3 on the higher end 2a side of the slope body 2 and the end on the lower end 2b side of the slope body 2 It is possible to both get on and off the wheelchair between the slope body 2 and the lower surface Gb through the head slope 3, and a wheelchair user or a wheelchair assistant can travel by passing through the slope device 1. The wheelchair can be moved continuously and lightly between the high-order surface Ga and the low-order surface Gb without changing the direction of the wheelchair in the middle, thereby ensuring safe driving of the wheelchair.

B: Second Embodiment FIG. 8 shows a slope device 1 according to a second embodiment of the present invention. This embodiment is a structure suitable for the case where the slope device 1 is bridged over a stepped portion higher than that in the first embodiment, and the slope body 2 is supported and fixed by a longer column 5. The slope end 2b of the slope body 2 is connected to, for example, a straight slope 6 having a single configuration and a long passage length.

  Therefore, the slope device 1 of this embodiment can be applied to a larger step portion without greatly changing the specification, and is effective in expanding the application range of the slope device 1. In addition, the structure except the above, an effect, etc. are the same as that of the said 1st Embodiment, The corresponding description is used.

C: Third Embodiment FIG. 9 shows a slope device 1 according to a third embodiment of the present invention. In this embodiment, in the first embodiment, the high-order end 2a of the slope body 2, that is, the high-order end member 22A portion is positioned in front of the high-order surface Ga, and the high-order end member 22A is disposed. The high-end side end member 22A of the slope main body 2 is positioned on the high-level surface Ga while being supported and fixed by the support columns 5 provided at both ends thereof. The lower side end is supported by the high level surface Ga, while the high side end is supported by the support column 5 arranged between the high level surface Ga.

  In the slope device 1 in this state, the slope device 1 can be brought closer to the stepped surface Gc side than in the case of the first embodiment, so even if the space on the near side of the stepped surface Gc is smaller, There is an advantage that the slope device 1 can be installed. Further, by supporting one end side of the high-end side end member 22A of the slope main body 2 on the high-order surface Ga, the number of the columns 5 can be reduced, and at the same time, it is economical and the slope device 1 There is also an advantage that the installation work can be simplified. In addition, the structure except the above, an effect, etc. are the same as that of the said 1st Embodiment, The corresponding description is used.

D: Fourth Embodiment FIG. 10 shows a slope device 1 according to a fourth embodiment of the present invention.

Is set so as to be substantially parallel to the step surface Gc, in this embodiment, the slope device 1 is rotated by a predetermined angle in a plan view, and the travel line in the lower-side end member 22B. Is inclined outward from the step surface Gc.

  According to such a configuration, since the travel line in the lower-side end member 22B is separated from the step surface Gc, for example, there is an obstacle in a region immediately before the step surface Gc, and the travel line is parallel to the step surface Gc. Then, even when there is a concern about interference between the wheelchair and the obstacle, there is an advantage that it is possible to safely get on and off the slope device 1 while avoiding such interference. In addition, the structure except the above, an effect, etc. are the same as that of the said 1st Embodiment, The corresponding description is used.

Fifth Embodiment FIG. 11 shows a slope device 1 according to a fifth embodiment of the present invention. In the slope device 1 in each of the above embodiments, the slope main body 2 is formed in a spiral plate shape that is curved at a substantially right angle from the high end 2a to the low end 2b in plan view. In the embodiment, the bending angle in plan view of the slope body 2 is set to an acute angle.

  According to such a configuration, since the travel line at the lower end 2b is greatly separated from the step surface Gc, even if there is an obstacle in the vicinity of the step surface Gc, this can be easily avoided. Thus, the slope device 1 can be installed, and there are advantages that the degree of freedom of the installation is improved and the traveling performance of the wheelchair is improved because the distance of the curved traveling is shortened.
