  However, when evaluating from the viewpoint of elasticity and shock-absorbing property, the flooring material described in Patent Document 1 has only the effect of cushioning due to the characteristics of the material, and the flooring structure itself has elasticity and shock-absorbing property. Is not considered. Therefore, it cannot produce an effective and dramatic counter force against the stress at the time of stairs climbing, and it is not sufficient for assisting elderly people, handicapped persons and the like.

In addition, in the case of the flooring described in Patent Document 2, although it is expected to contribute to the improvement of cushioning properties by certainly including a foamed synthetic resin layer, this is simply arranged with a member having cushioning properties. This structure is a structure in which only a part of a conventional member is arranged into a material having cushioning properties, and it cannot be said that the structure itself has been devised for elasticity and shock-absorbing properties.
The present invention has been made in order to solve such problems in the prior art, and lays a step on a staircase to improve elasticity and shock absorption. For example, when an elderly person or a disabled person climbs a staircase, The purpose of the present invention is to provide an auxiliary device for raising and lowering stairs that can reduce the burden on the body of the person who goes up and down the stairs, especially the leg, and can be expected to reduce the load when going down the stairs.

  In other words, a structure that only gives the cushioning effect due to the characteristics of the material, a structure that simply arranges a member having a cushioning property, or a structure that only arranges a part of the member to a material having a cushioning property, Unlike conventional structures that cannot be said to be devised in terms of elasticity and buffering, the steps are laid on the stairs to improve elasticity and buffering. The purpose of the present invention is to provide an auxiliary device for raising and lowering stairs, which provides an auxiliary effect when climbing and a load reducing effect when descending stairs, and reduces the burden on the body of a person who moves up and down the stairs, particularly the leg.

  In order to achieve such an object, a stair climbing auxiliary instrument according to the present invention includes a bottom surface fixed to a tread surface of a staircase, a step surface coupled to the bottom surface and inclined with respect to a horizontal plane, and the bottom surface and the step surface. A step structure having a connecting surface formed substantially flush with a staircase finding surface, and an inner surface formed by the step structure, and a back surface and a bottom surface of the step surface. And an elastic structure that is elastically connected. The “elastic structure” in this case refers to a structure that widely includes elastic structures such as springs, metal plates, resin plates, air cushions, and the like.

  With this configuration, when an elevator climbs the stairs, the step surface connected to the bottom surface fixed to the tread surface of the staircase and the elastic structure disposed on the inner surface rise integrally. Since it repels against the load of time, it will assist the climbing movement. In addition, when it goes down, the elastic structure integrated with the treadle surface acts as a cushion (buffer), reducing the burden on the legs (load repulsive force) when the elevator goes down the stairs It becomes possible to do.

  At this time, the bottom surface and the tread surface of the staircase may be configured to be fixed using a bolt or an adhesive. By constructing in this way, the above-mentioned auxiliary equipment for raising and lowering the stairs can be easily and independently constructed separately from the main body construction of the house, not only increasing the convenience of construction, but also by using bolts or adhesives, It is possible to eliminate the deviation between the above-mentioned auxiliary equipment for raising and lowering the stairs and the stairs, and to realize safe elevating equipment.

  Further, the elastic structure may be configured such that one end is a spring connected to the back surface of the step surface and the other end is connected to the bottom surface. By configuring in this way, the elastic structure has both elasticity and rigidity, and can be realized as an auxiliary device for raising and lowering stairs that expects a safety factor several times the human weight.

  Moreover, you may comprise the said elastic structure so that it may be an elastic body inscribed in the back surface and bottom face of the said step surface at least. By configuring in this way, the elastic structure increases durability in addition to the above features. At this time, the elastic body may be configured to be a substantially flat metal body or resin body having a certain rigidity. In this way, mass production at a low cost becomes possible. Further, at this time, the elastic body can be configured to be a wooden structure or an air cushion which is made of wood pieces and has elasticity. According to this configuration, in addition to the above features, it is possible to provide a housing facility that takes into account a natural flavor or a housing facility that can obtain a softer feel.

  Moreover, you may comprise so that a cover material may be further provided so that the finding surface of the said staircase and the said connection surface may be covered. By configuring in this way, it is possible to make the finding surface of the stairs visually uncomplicated.

  Further, the present invention is a step structure comprising a bottom surface fixed to a tread surface of a staircase, a step surface coupled to the bottom surface and having an inclination with respect to a horizontal plane, and disposed inside the step structure. An elastic structure that elastically connects the back surface and the bottom surface of the step surface may be provided. According to such a configuration, the above-described effect can be obtained even in a configuration in which there is no finding surface in the step structure. In other words, when a lifter climbs a staircase, the step surface connected to the bottom surface fixed to the tread surface of the staircase and the elastic structure disposed on the inner surface are integrated to repel the load during ascent. Therefore, it will assist the climbing exercise. In addition, when it goes down, the elastic structure integrated with the treadle surface acts as a cushion (buffer), reducing the burden on the legs (load repulsive force) when the elevator goes down the stairs It becomes possible to do.

  補助, the stair climbing auxiliary equipment (stair step) according to the present invention includes a bottom surface in contact with the step surface of the staircase, a step surface arranged to have a slight inclination angle with the step surface of the stair, and the bottom surface and the step surface. Are connected and integrated so that they may have a slight inclination angle, and a spring is arranged so as to generate a stress with respect to a load during elevation.

  With this configuration, steps and steps are laid on the stairs to improve elasticity and cushioning.For example, elderly people and people with physical disabilities can assist when going up the stairs and reduce the load when going down the stairs. It is possible to provide an auxiliary device for ascending and descending stairs that reduces the burden on the body of the person performing the exercise, particularly the leg.

  The spring constituting the step of the present invention may use not only metal but also non-metal such as wood as a material.

  According to the present invention, a step is laid on a staircase to improve elasticity and cushioning, for example, providing an assist effect when an elderly person or a disabled person goes up the stairs, a load reducing effect when going down the stairs, It is possible to provide an auxiliary device for raising and lowering stairs that reduces the burden on the body of a person who moves up and down, particularly the leg.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing the whole and outline of a stair climbing auxiliary device according to an embodiment of the present invention, and FIG. 2 is a sectional view of the whole stair climbing auxiliary device.

  As shown in the drawings, the stair lifting / lowering auxiliary device 1 is fixed to a tread surface 10 of a stair that connects between a lower floor (not shown) and an upper floor 30 by using, for example, a bolt 40 or the like. The auxiliary device 1 for raising and lowering the staircase 1 includes a bottom surface 12, a finding surface (joint surface) 18, and a step surface 14 that is formed substantially horizontally or may have a slight gradient with respect to a horizontal plane ( And a flat plate bent body having a substantially U-shaped cross-section (referred to as a “step platform structure”) formed integrally or connected to each other. An elastic structure (for example, a spring 16) which is attached so that the inside of the bottom surface 12 and the step surface 14 is connected to one to several appropriate positions near the opening end of the step structure (the end close to the stair lift 20). Formed with.

  At this time, instead of the bolt 40, for example, the upper surface of the step surface 10 of the staircase and the lower surface of the bottom surface 12 of the step structure may be bonded using an adhesive (not shown). In addition, here, the structure in the case of having the finding surface (joint surface) 18 will be described as an example, but in this case, due to the provision of the find surface (joint surface) 18, the substantially horizontality when the weight is placed on the stepping surface 14. Will be more secured and safety will be improved. However, this finding surface (joint surface) 18 is not essential, and a structure without this find surface (joint surface) 18 may be used.

  The step structure formed by the bottom surface 12-the finding surface 18-the step surface 14 is not limited as long as it is a material having a certain rigidity and a flat plate shape. For example, a single flat plate made of metal, resin or the like is used. It may be bent. Or what connected the wooden plate may be used.

  In addition, by appropriately adjusting the distance between the footrest surface 14 and the stepped-up surface 20 and making the gap width minute, the risk of the footwear or heel portion being caught in the gap can be minimized.

  FIG. 3 is a diagram showing a more detailed cross section of the elastic structure.

  As shown in FIG. 1A, the spring 16 is made of a material having moderate elasticity and constant rigidity. In FIG. 1, for example, the case of three attachments in plan view is shown, but at least or more than this may be used. Here, the spring 16 will be described as an example of the elastic structure. However, instead of this, for example, as shown in FIG. Alternatively, a flat plate (for example, tin plate) bending structure (using a repulsive force against bending) 17 may be used. Although not shown, an air cushion or the like may be used as the elastic structure.

  4 to 8 are plan views for explaining various forms of the footrest structure. That is, as shown in FIG. 4, as shown in FIG. 4, an elastic structure may be disposed at three locations of the center portion and both end portions of the planar position, but instead, as shown in FIG. 5, A large number of elastic structures may be arranged with a slight clearance dimension over a greater number of locations, for example, approximately the entire length of the step surface 14 in the depth direction of the cross section. Or as shown in FIG. 6, you may arrange | position a single elastic structure to the substantially whole surface-fixed range of the back surface of a step structure.

  Further, the elastic structure may be arranged in a plane position close to the closed end of the step structure having a substantially U-shaped cross section as shown in FIG. Alternatively, the step surface 14 may be disposed over substantially the entire length in the longitudinal direction of the cross section.

  Next, the operation / function of the stair climbing auxiliary instrument 1 according to the present invention configured as described above will be described.

  When going up the stairs, a load is generated when an elevator (not shown) steps on the step surface 14 (puts the back of the foot on the step surface 14). The load is subjected to a certain repulsion due to the rigidity and elasticity of the footrest structure formed by the bottom surface 12-the finding surface 18-the footrest surface 14, but most of the load is transmitted to the spring 16. Due to the elasticity of the spring 16, the lifter receives a certain assisting force / promoting force from the stair lift assisting device 1. Thereby, it can become an assistance at the time of going up the stairs. Therefore, for example, even an elderly person or a physically handicapped person can be assisted so that an operation of climbing stairs can be performed without requiring labor.

  On the other hand, when going down the stairs, a load generally larger than that when going up is applied to the step surface 14 of the step structure and is transmitted to the spring 16 by the force transmission structure similar to the above. Here, due to the elasticity of the spring 16, the repulsive force applied to the legs of the lifter is alleviated, and for example, the burden is reduced on a person who does not necessarily have a strong leg, such as an elderly person. Therefore, if a certain range of rigidity / elasticity of the spring 16 is selected, it acts as a cushion when descending, and it is possible to assist a smooth descent operation without causing an excessive repulsive force.

  Here, the case of the spring 16 has been described as an example, but a metal plate such as a tin plate, a resin plate, an air cushion, or the like may be used, and the above description can be applied to these cases.

  As described above in detail, according to the auxiliary equipment for raising and lowering stairs according to the present invention, the steps are laid on the stairs to improve the elasticity and the shock-absorbing property, for example, when an elderly person or a disabled person goes up the stairs. It is possible to provide an auxiliary device for raising and lowering stairs that provides an auxiliary effect and an effect of reducing the load when going down the stairs, and reduces the burden on the body of the person who goes up and down the stairs, particularly the leg.

  The present invention is not limited to the above-described embodiment, and various modifications, additions, substitutions, expansions, reductions, etc. to the above-described embodiment are allowed within the scope of the same and equivalent technical idea. Is.

  Further, what has been described above is merely an example of an embodiment for realizing the technical idea of the present application, and the technical idea of the present application can be applied to other embodiments. For example, in the above description, a mode in which the mechanism is realized by using a spring shape as a U-shaped curved spring has been described. However, the mechanism does not exclude the possibility of other spring shapes and other elastic structures. Any mechanism provided with an elastic structure on the platform and having elasticity and buffering properties is included in the scope of the technical idea of the present application.

  For example, FIG. 9 is a perspective view of a step structure according to another embodiment of the present invention, and FIG. 10 is a cross-sectional view of FIG. As shown in the figure, according to the present invention, a slip having a constant width is found on the side of the finding surface (joint surface) 18 on the step surface 14 (in the figure, a case where a slight gradient is given to the horizontal plane). The stop 50 may be laid over a certain length, preferably over the length of the stepped surface 14 or slightly shorter. The anti-slip 50 is made of a material such as sponge or rubber in the form of a sheet (for example, the thickness is about 0.5 to 5 mm), and this is joined to the step surface 14 with an adhesive, a screw or the like. By doing in this way, it is possible to remove the ease of slipping on the step surface 14 of the stairs and achieve a safer lifting operation.

It constructs so that the finding surface (joint surface) material 18 and the footrest surface 14 may be attached to this crosspiece 52. By doing so, not only the convenience in construction is improved, but also the durability, resilience and the like of the auxiliary device for raising and lowering the stairs 1 itself are enhanced. Furthermore, even if excessive weight is applied to the footrest surface 14 due to the presence of the pier 52, the spring 16 is protected by securing a certain height. At this time, the pier 52 is not limited to wood, and plastic, metal, or the like can be used as a material. Further, depending on the combination with the material, the bottom surface 12, the finding surface (joint surface) material 18 and the step surface The 14 materials may also be plastic, metal or the like.

  Further, as shown in FIG. 4B, the flat plate joining structure 54 may be joined to the cross sections of the bottom surface member 12 and the footrest surface material 14 by, for example, wood screws 56. As the flat joint structure material 54, for example, an iron plate, a non-rusting material such as a true casting, or a rust-proof material is used. A joining material that enables free rotation of a bolt or the like is used for a joining portion between the flat plates. By configuring in this way, the rigidity of the footrest structure formed by the bottom surface 12-the finding surface 18-the footrest surface 14 is further increased, so that safety can be further improved. For example, an excessive load is applied to the spring 16. Even when added, the repulsive force can be suppressed within a certain range, and the danger of excessive repulsion can be avoided.

  Furthermore, FIG. 12 shows a sectional view of a step structure according to still another embodiment of the present invention, and is a space formed by being surrounded by the bottom surface 12, the finding surface (joint surface) 18, and the step surface 14.

As shown in the figure, a hinge 58 is disposed between the crosspiece 52 and the back surface of the footrest surface 14, and the respective members are joined with, for example, a wood screw (not shown). By adopting such a structure, the rigidity of the step structure is further increased, so that the safety can be further improved.

  In addition, for example, in the above description, a spring may be installed on the step surface from the beginning of the stairs itself to constitute a mechanism having elasticity and buffering properties. Further, the step structure may be composed of two flat plates of the bottom surface 12 and the step surface 14.

  Furthermore, you may comprise so that a cover material may further be provided so that the finding surface of a staircase and the connection surface 18 of the auxiliary | assistance apparatus for raising / lowering this staircase may be covered. By configuring in this way, the finding surface of the staircase can be made visually uncomplicated.

As shown in the figure, the step structure formed by the bottom surface 12, the finding surface (joint surface) 18, and the step surface 14 may be configured to be approximately half the finding width of the stairs 30. At this time, a handrail 60 may be provided on the side where the step structure is formed (the left side in the figure). By comprising in this way, a step structure (and a handrail) can be utilized for an elderly person or a disabled person, and a normal person can utilize a normal staircase. At this time, the staircase width can be slightly longer than usual, and by doing so, the safety can be further improved.
