Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flat handrail capable of supporting a body while a person who has difficulty walking or the like slides a hand or an elbow tip portion (hereinafter referred to as “lower arm portion”), and a method for attaching the flat handrail.
[0002]
[Prior art]
Conventionally, for people who are difficult to walk, such as elderly people and sick people, handrails are provided in rooms, hallways, etc. to assist walking. However, elderly people, sick people and the like often have difficulty in supporting the body by grasping the handrail because the hand grip strength is weak. For this reason, a handrail has been proposed that allows walking with the palm or lower arm resting on the palm and leaning on the weight and sliding the palm or lower arm (Patent Document 1).
[0003]
This prior art is shown in FIG. That is, the handrail member 10 has a main body portion 10A and a grip portion 10B. The main body portion includes an attachment surface 11 to the wall surface W and a flat surface 12 that can support the lower arm portion of the pedestrian. ing. The grip portion 10 </ b> B extends from the main body portion 10 </ b> A to the pedestrian side, and its upper portion 19 is formed to protrude upward from the flat surface 12.
[0004]
[Patent Document 1]
JP-A-8-1114016 (pages 1-5, FIG. 4)
[0005]
[Problems to be solved by the invention]
However, the above prior art has the following problems to be improved. First, the grip portion 10B is positively provided at the distal end portion of the flat surface 12, and the upper portion 19 of the grip portion is flat so that the lower arm portion placed on the flat surface does not slide down. It is formed so as to protrude upward from the surface. However, if the upper portion 19 protruding from the flat surface 12 is provided, the protruding upper portion becomes an obstacle, and it becomes difficult to place a vase, a figurine or the like horizontally. On the other hand, if walking assistance is no longer needed or until it becomes necessary in the future, if a figurine or the like can be placed on this handrail, the utility value will be greatly improved.
[0006]
Second, as long as the grip portion 10B is positively provided, it is natural to make the shape as easy as possible with the palm as much as possible. For this purpose, the apex of the upper portion 19 protruding from the flat surface 12 naturally has a smooth circular cross-sectional shape. Will form. However, if it is formed in a smooth arc cross-sectional shape, the frictional force is reduced, and the palm and lower arm portion placed on the flat surface 12 are likely to slide outward. Therefore, in order to make it easy to grip with the palm and make it difficult for the palm and lower arm portion to slide outward, the upper portion 19 of the grip portion 10B as described in the attached FIG. Is a position protruding from the flat surface 12 to some extent. For this reason, when the lower arm is placed on the flat surface 12 and slid with its weight, the wrist or elbow may come into contact with the apex of the arc cross-sectional shape in a so-called line contact state, which may be painful. Especially for elderly people who have lost their flesh and those who have weak physical strength, the wrist and arm bones directly hit the apex of the arc cross-sectional shape, resulting in increased pain.
[0007]
By the way, when it is difficult to walk, it is often difficult to walk while supporting the body by grasping the grip portion 10B, since the physical strength is reduced and the grip strength is weak. On the other hand, when the grip portion 10B is gripped enough to support the body, if the end portion of the flat surface 12 is gripped, the body can be sufficiently supported. Therefore, it is considered unnecessary to provide the grip portion 10B on the flat surface 12.
[0008]
Thirdly, when the handrail is used by being connected in the longitudinal direction, a level difference is likely to occur in the connected portion during connection or due to subsequent aging. Fourth, at the corners of corridors, etc., it is necessary to cut the handrails according to the angle of the corners and connect the cut surfaces to each other. Is likely to occur. Fifth, it takes time and effort to directly fix the long handrail to the wall surface with a screw or the like while holding it at a predetermined mounting position.
[0009]
Accordingly, the present invention provides a flat handrail that improves the above-described practical problems of the prior art and a method for mounting the same.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a first feature of the flat handrail according to the present invention includes an attachment portion to a wall surface and a handrail portion protruding from the attachment portion, and an upper surface of the handrail portion is a floor surface. It is a handrail surface parallel to at least the longitudinal direction, and this handrail surface is provided with a finger guide part continuous in the longitudinal direction, while the lower surface of this handrail part is that the entire surface is a flat horizontal surface. . And it can attach to the said wall surface upside down with the handrail surface and a horizontal surface, and this horizontal surface can be used as a horizontal shelf .
[0011]
A second feature of the flat handrail according to the present invention is that the finger guide portion described in the feature 1 includes a flat surface having a predetermined width inward from an outer end of the handrail surface, and a predetermined width from the flat surface. That is, it is a level difference from the inner side surface having a predetermined width and being lower than the dimension. Furthermore, the third feature of the flat handrail according to the present invention is that the finger guide portion described in the feature 1 includes a protrusion , and the handrail surface described in the feature 1 has an outer side and an inner side sandwiching the protrusion. It is a flat surface, and the cross section of the protrusion is in a semicircular shape having a height of about 3 mm .
[0012]
By configuring the invention in this way, the following effects can be obtained. First, since the surface on the opposite side of the handrail surface on which the palm or lower arm is placed is a horizontal surface, if this surface is attached to the top surface, the entire surface without projections can be used as a flat horizontal shelf. . Therefore, since it can be used as a shelf on which figurines, vases, etc. can be placed when walking assistance is no longer needed or until walking assistance is required in the future, the utility value is greatly improved.
[0013]
Secondly, a finger guide made of, for example, a step or a protrusion is provided on the handrail, so that when walking with the palm or lower arm placed on the handrail, the fingertip and the like follow the finger guide. By doing so, the position of the palm or lower arm placed on the handrail can be confirmed. For this reason, it is avoided that the palm and the lower arm part are shifted to the outside of the handrail part, and it is possible to prevent the palm and the lower arm part from slipping down from the handrail part. Thirdly, by forming, for example, a step or protrusion as a finger guide, frictional resistance is generated with respect to the movement of the palm or lower arm of the step or the like to the outside, and the effect of preventing sliding down is obtained. It is done. In order to generate a frictional resistance against the movement of the palm or the lower arm part to the outside, it is sufficient to form the step or the protrusion so as to be high enough to feel with a finger.
[0014]
Fourth, the handrail surface on which the palm or lower arm is placed is not actively provided with a gripping part that protrudes upward, so when sliding with a weight, the wrist or elbow hits this protruding part. You can avoid getting hurt. That is, only a step or a protrusion that is continuous in the longitudinal direction is formed on the handrail surface. However, as described above, this step needs only a slight height, and since the outside of the step is a flat surface having a predetermined width, the load is flat even if the wrist or elbow hits the flat surface. Since it is dispersed on the surface, it is possible to avoid pain. Further, as described above, since the projecting portion needs only a slight height, the touch of the wrist and the elbow is low, and no pain occurs.
[0015]
A fourth feature of the flat handrail according to the present invention is that a connecting groove continuous in the longitudinal direction is formed on the horizontal surface of the handrail portion described in any one of the features 1 to 3. The connecting reinforcing member can be fitted into the connecting groove, and when the handrail portion is connected, the connecting reinforcing member is continuously fitted to the connecting portion so that the connecting portion It eliminates the steps.
[0016]
That is, if there is a level difference in the connecting part that connects the flat handrail in the longitudinal direction, the palm and lower arm part are caught during walking and cannot be easily slid. However, it takes a lot of labor to fix the long flat handrail to the wall surface while aligning it so that no step is generated. Moreover, even if it is attached so that no step is generated, a step is often generated in the connecting portion due to a secular change due to long-term use. Therefore, by attaching a connection reinforcing member to the connection part and forcibly fixing the connection part, it is possible to facilitate the alignment at the time of connection and to prevent a step due to a secular change or the like. In addition, by fitting the connecting reinforcing member into the connecting groove continuous in the longitudinal direction, a horizontal surface can be secured when used as a shelf, and a step is prevented from being generated in a direction perpendicular to the wall surface. can do.
[0017]
A fifth feature of the flat handrail according to the present invention is that the wall surface of the attachment portion is left with a surface layer having a predetermined thickness between the outer end of the handrail portion described in any one of the features 1 to 4. A V-groove that opens at a predetermined angle from the mounting surface to the outer end of the handrail portion is cut out, a surface layer located at the top of the V-groove is bent, and the V-groove cut-out surface It is in having a corner part which joined.
[0018]
That is, at corner portions such as the corners of corridors, it is necessary to cut the flat handrails according to the angle of the corners and connect the cut surfaces to each other. However, when connecting, it is difficult to fix the flat handrail to the wall surface so that no step is formed on the cut surface. Therefore, finishing work such as cutting the step is required. Further, there are many cases where a level difference occurs on the cut surface due to secular change or the like. In this case, a large-scale repair work such as scraping the level difference and repainting is required. Therefore, the V-groove is cut out at the top of the corner portion leaving a foldable surface layer composed of a continuous portion, and the continuous portion is bent and joined so that the cut-out surface of the V-groove is matched. At this time, there is no step in either the vertical direction or the horizontal direction due to aging. Also, handrails can be easily connected to different corner angles simply by changing the notch angle of the V-groove.
[0019]
Moreover, in the handrail of the conventional example mentioned above, as shown in FIG. 10, the grip part 10B is provided, and in order to make this grip part into the shape which is easy to grip, the outer end is formed in circular arc cross-sectional shape. However, when the outer end of the handrail has an arc cross-sectional shape, when the V groove is cut out, only a surface layer having a minute arc length remains between the top of the V groove and the outer surface. Therefore, when a corner portion is formed by bending such a continuous portion having a small area, there is a problem that the surface layer is cut or wrinkles are generated.
[0020]
On the other hand, in the present invention, since the grip portion is not actively provided, it is not necessary to make the outer end of the handrail into an arc cross-sectional shape, and it is sufficient to make the outer end of the handrail into a rectangular cross-sectional shape as described later. Therefore, when the V-groove is cut out, a surface layer corresponding to the height of the outer end surface can be left between the top of the V-groove and the outer surface. The corner portion can be formed without causing wrinkles. Therefore, a straight portion, a corner portion, a protruding corner portion, and the like can be continuously formed using a single direct material.
[0021]
A sixth feature of the flat railing attachment method according to the present invention is that the attachment portion described in any one of the features 1 to 5 is temporarily fixed to the wall surface with an adhesive member, and then the wall surface is attached by the attachment screw. There is to fix to.
[0022]
That is, it is not easy to directly attach a long flat handrail to a wall surface with a mounting screw while holding it at a predetermined attachment position, and it is not easy to correct the position after attachment. On the other hand, for example, if a double-sided adhesive member is used, the flat handrail can be temporarily fixed at a predetermined position relatively easily. In addition, since it is temporarily fixed, the position can be easily corrected. Therefore, if the flat handrail is temporarily fixed with an adhesive member and then finally fixed with an attachment screw, it can be easily fixed at a predetermined attachment position.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
The structure of the flat handrail according to the present invention will be described with reference to FIGS. That is, the flat handrail is obtained by integrally extruding a hard foamed resin mixed with wood powder, and has a grain feel and antibacterial properties. The flat handrail protrudes from the attachment portion 1 having a vertically long rectangular cross section having a height of about 75 mm and a width of about 10 mm, and the central portion of the outer surface 11 of the attachment portion, and has a protrusion length of about 70 mm and a thickness. Has a handrail portion 2 of about 20 mm. One of the upper and lower surfaces of the handrail portion 2 is a handrail surface 21 parallel to the floor surface and the longitudinal direction. Further, the handrail surface 21 has a flat surface 211 having a width of about 20 mm inward from the outer end thereof, and a flat inner surface 212 having a width of about 3 mm lower than the flat surface by a step 213 of about 3 mm. Is formed. The other of the upper and lower surfaces of the handrail portion 2 is a horizontal plane 22.
[0024]
Further, a connecting groove 221 continuous in the longitudinal direction is formed on the horizontal surface 22 of the handrail part 2, and as will be described later, the connecting reinforcing member for eliminating the step of the connecting part of the handrail part is provided in the connecting groove. 23 is fitted. The outer surface 11 of the mounting portion 1 is provided with mounting screw grooves 12 and 12 which are continuous in the longitudinal direction on both sides of the handrail portion 2 projecting from the central portion thereof. A decorative plate 13 that covers the head of the mounting screw 14 is fitted in the screw groove.
[0025]
FIG. 2 shows a case where the handrail surface 21 is attached to a wall with the top surface used as a flat handrail. On the other hand, FIG. 3 shows a case where the horizontal surface 22 is attached to the wall as an upper surface and used as a horizontal shelf. Further, as shown in FIG. 3, when the horizontal surface 22 is the upper surface, a long material is used as the connection reinforcing member 23 in the connecting groove 221 in order to flatten the entire surface of the horizontal surface. It is made to fit continuously so that a level | step difference may not arise. On the other hand, as shown in FIG. 2, when the horizontal surface 22 is the lower surface, it is not necessary to flatten the entire surface of the horizontal surface, and the connection groove 221 has a short connection reinforcing member only at the connection portion of the handrail portion 2. 23 may be fitted.
[0026]
Another embodiment of the present invention will be described with reference to FIGS. The numbers corresponding to the components shown in FIG. 1 to FIG. In other words, the flat handrail is formed by integrally extruding a hard foam resin mixed with wood powder, as described above, and has a vertically long rectangular cross section having a height of about 75 mm and a width of about 10 mm. 1001 and a handrail portion 1002 projecting from the center of the outer surface 1011 of the mounting portion and having a protrusion length of about 70 mm and a thickness of about 20 mm. One of the upper and lower surfaces of the handrail portion 1002 is a handrail surface 1021 that is horizontal to the floor surface at least in the longitudinal direction. The handrail surface is continuous as a finger guide portion in the longitudinal direction, and an outer end of the handrail surface. Two protrusions 1214 having a height of about 3 mm, which are arranged in parallel, are provided. Note that the cross section of the protrusion 1214 is formed in a semicircular shape. Further, on the handrail surface 1021, a flat surface 1211 having a step 1213 of about 3 mm and a width of about 20 mm is formed from the outer end to the inside. The step 1213 reinforces the same function as the projection 1214 by creating a fingertip guide and a frictional resistance that prevents the palm and lower arm from slipping outward. A flat surface 1211 may be formed.
[0027]
Further, a connecting groove 1221 that is continuous in the longitudinal direction is formed on the horizontal surface 1022 of the handrail portion 1002, and as will be described later, the connecting reinforcing member for eliminating the step of the connecting portion of the handrail portion is provided in the connecting groove. 1023 is fitted. The outer surface 1011 of the mounting portion 1001 is provided with mounting screw grooves 1012 and 1012 which are continuous in the longitudinal direction on both sides of the handrail portion 1002 projecting from the central portion thereof. A decorative plate 1013 that covers the head of the mounting screw is fitted into the screw groove.
[0028]
FIG. 5 shows a case where the handrail surface 1021 is attached to the wall as the upper surface and used as a flat handrail. On the other hand, FIG. 6 shows the case where the horizontal surface 1022 is attached to the wall as the upper surface and used as a horizontal shelf.
[0029]
Next, a method for attaching the above-described flat handrail will be described with reference to FIG.
First, the baseboard 7 is attached along the corner between the lower end of the wall 3 and the left end of the floor 4. The upper end of the skirting board 7 is formed with a notch 7 a in the longitudinal direction. The lower end of the waist wall 6 is inserted into a vertical groove formed between the notch and the wall 3. Screw on the wall. The left and right ends of the waist wall 6 are respectively formed on an uneven surface, and the unevenness is inserted and connected to each other. Then, the attachment plate 5 is temporarily fixed to the wall 3 with a double-sided adhesive tape (not shown) at the upper end of the waist wall 6. A notch 5a is formed at the lower end of the attachment plate 5 in the longitudinal direction, and the attachment plate is bonded to the wall 3 so that the notch covers the upper end of the waist wall 6. The mounting plate 5 is secured in contact with the upper end surface of the waist wall 6 to secure the height and level, but is peeled off from the wall 3 as necessary to correct the mounting position.
[0030]
A horizontal groove 5b is formed on the outer surface of the mounting plate 5 in the longitudinal direction, and a double-sided adhesive tape (not shown) is applied to the horizontal groove, and then the flat handrail mounting portion 1 is fitted and bonded. To do. And, as will be described later, after connecting the flat handrails in the longitudinal direction and confirming that there is no level difference in the connecting portion or horizontal deviation, screw the mounting screws 14 into the mounting screw grooves 12, 12, Secure to the wall 3. Finally, the decorative plate 13 is fitted and bonded to the mounting screw grooves 12 and 12 to cover the head of the mounting screw 14.
[0031]
When connecting the flat handrails in the longitudinal direction, the connecting reinforcing member 23 is fitted and bonded to the connecting groove 221 provided in the horizontal surface 22 so as not to forcibly produce a step in the vertical and horizontal directions, and then attached to the mounting screw. 14 to the wall 3. The connecting portion is fixed with an adhesive. If the flat handrail is turned upside down, the mounting screw 14 is removed, the flat handrail bonded with double-sided tape is peeled off from the horizontal groove 5b of the mounting plate 5, and the flat handrail is turned upside down and re-fitted into this horizontal groove. It is only necessary to bond and re-fix to the wall 3 with this mounting screw.
[0032]
The means for forming the corner portion of the flat handrail will be described with reference to FIGS. FIG. 8 shows a case where the angle of the corner is 90 degrees. That is, first, as shown in FIG. 8A, a 90-degree V-groove 8 is cut out from the attachment portion 2 toward the handrail portion 1. A surface layer having a thickness of 3 to 5 mm is left between the top 8 b of the V groove 8 and the outer end face of the handrail 1. Next, as shown in FIG. 8B, the surface layer located at the top 8b of the V-groove 8 is bent at a right angle, and the cut-out surfaces 8a and 8a of the V-groove are aligned and bonded with an adhesive or the like. Accordingly, since the outer surface of the corner portion is bent continuously and integrally, there is no step in this portion. In addition, since the outer surfaces are not integrally connected and separated, it is difficult for a step to be formed on the upper and lower surfaces of the corner portion.
[0033]
FIG. 9 shows a case where the angle of the corner portion is 120 degrees. That is, first, as shown in FIG. 9A, a 60-degree V-groove 1008 is cut from the attachment portion 1002 toward the handrail portion 1001, and then as shown in FIG. 9B, the top 1008b of this V-groove. The surface layer located at is bent by 60 degrees, and the notch surfaces 1008a and 1008a of the V-groove are combined and bonded with an adhesive or the like. Therefore, by changing the notch angle of the V-groove 1008, a flat handrail corresponding to the angle of an arbitrary corner portion can be formed.
[0034]
The flat handrail is not limited to the hard foam resin mixed with wood powder, and other synthetic resins and metal materials such as aluminum can also be used. In addition, by covering the surface of the flat handrail with a plastic material having a high elasticity, it is possible to reduce bruises in the event of an accident such as a fall. Further, the protrusions 1214 constituting the finger guide portion are not limited to two rows, and may be one row or three or more rows.
[0035]
【The invention's effect】
First, by forming the side opposite to the surface on which the palm or lower arm is placed on a horizontal plane, if this horizontal plane is mounted on the upper side, the entire surface without projections is flat until walking assistance is required. Since it can be used as a horizontal shelf, the utility value is greatly improved. Secondly, for example, by providing a step that is continuous in the longitudinal direction on the handrail surface or a finger guide portion that includes a protrusion parallel to the outer edge of the handrail surface, the palm and lower arm portion can be easily slid while guiding the fingertip. In addition, the palm and lower arm can be prevented from slipping down due to the frictional resistance generated by the steps and the protrusions.
[0036]
Third, the handrail surface on which the palm or lower arm is placed is not actively provided with a gripping part that protrudes upwards, so when sliding with a weight, the wrist or elbow hits this protruding part. You can avoid getting hurt. Fourth, by fitting the connecting reinforcing member into the connecting groove and forcibly fixing the connecting portion, positioning at the time of connecting is facilitated and a step due to secular change or the like is prevented. be able to. Moreover, the horizontal surface in the case of using as a shelf can be ensured by fitting a connection reinforcement member in the groove for connection.
[0037]
Fifth, the corner part is joined so that the V-groove is notched leaving the surface layer of the continuous part that can be bent at the top, and the notch surface of the V-groove is matched by bending this continuous part. As a result, there is no step in either the vertical direction or the horizontal direction during mounting or due to aging. Also, handrails can be easily connected to different corner angles simply by changing the notch angle of the V-groove. Therefore, the straight portion, the corner portion, and the protruding corner portion can be continuously formed with one direct material. Sixth, by first temporarily fixing the flat handrail with an adhesive member and then finally fixing with a mounting screw, a long flat handrail can be easily fixed at a predetermined mounting position. . Moreover, since it is a temporary fix | stop, attachment height and parallelism can also be corrected easily.
