Description

[0001]
[Industrial application fields]
The present invention relates to the structure and shape of handrails that are generally used.
[0002]
[Prior art]
Conventional handrails are round, square pipes or flats made of upper and lower or left and right parallel members, and most of them are parallel members. Further, even if it is not a parallel member at all, “the surface is uneven so that it is difficult to slip when a handrail rail is gripped and force is applied” (page 13 of Japanese Utility Model Publication No. 63-40426). (Refer to the 15th line to the 15th line), "It is formed by forming a plurality of concave shapes 2 in which the belly of the finger fits when gripped by hand on the outer surface of the rod-shaped material 1" (Japanese Utility Model Laid-Open No. 6-58030) Page 19th to 21st lines), etc., and some have been changed partially.
[0003]
[Problems to be solved by the invention]
The conventional parallel outer shape is dangerous for elderly people with weak grip strength and those who are rehabilitating because it is difficult to grip the handrail or it is easy to slide while there is a handrail.
[0004]
In addition, when the surface of the handrail rail is uneven due to a partial change, or when a plurality of concave ridges are formed, the resistance against slipping by the fingertips is partly increased. By changing the outer diameter of the handrail with respect to the vertical position of the handrail, the hand grip is weakened according to the shape of the hand gripping the outer periphery of the handrail, making it easier for people with disabilities to grasp the handrail and stabilizing the body Not attracted.
[0005]
From the above, the present invention is a handrail formed by utilizing the ergonomic property that the degree of opening of the finger naturally changes depending on the distance between the position of the center of the body and the position of the hand. . That is, when the palm naturally falls around the waist, which is the center of the body, and approaches the center of the body, the fingers of the hand are held almost flat and open on the flat surface. It is convenient to grab wide objects. On the other hand, when the palm of the hand is far from the center of the body, just above the head, the fingers of the hand are naturally gripped and are relatively thin, such as tree branches and horizontal bars Convenient for grabbing things. In this way, a handrail is formed in accordance with the natural shape of the hand, the ease of grasping the hand against the handrail, the natural gripping force, etc. are pulled out to obtain body stability and attraction, and as a whole it is safe and reliable A handrail is provided.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a longitudinal member having a cross section convenient for hand-clamping is arranged in a vertical direction in accordance with the body, and the lower part of the outer diameter of the cross section of the member is large. A handrail that has a small diameter on the top and a continuous outer diameter.
[0007]
In addition, the above-mentioned member is arranged in a lateral direction in accordance with the body, the outer diameter of the cross section of the member is made large in the vicinity of the body center position, and is made smaller as it gets away from the body center position, and the outer shape is continuous. A handrail that is formed automatically.
[0008]
Further, the above-mentioned member is arranged in an arbitrary direction according to the body of the movement operation, and the outer diameter of the cross section of the member is set to a large diameter near the body center position before the movement operation and away from the body center position. The handrail has a small diameter according to the above and the outer diameter is continuously formed.
[0009]
In addition, the member may be formed in a flat or uneven outer shape, a mounting member may be mounted on a parallel member, or a combination of the above-described various members or parallel members along the body flow line may be integrated as a whole. Of the handrail.
[0010]
[Action]
The above-mentioned handrail is mounted vertically on the door side of the entrance door, on the door frame outside the knob, or on the wall in the vicinity of the knob. The height position should be approximately the same. The position of the knob is slightly above the center of the body (around the waist for adults), the fingers of the hand are half open, and the handrail is set to the optimum grip thickness. Can hold and stabilize. In addition, when the palm of the hand is taken above the grip position of the handrail, the handrail is thinner and the hand is higher than the center of the body, and the fingers of the hand are further gripped. A state is obtained. Conversely, when you bring your hand below the middle of the handrail, the hand is located near the center of the body, and the open state of the fingers of the hand is half open and open, and naturally thick handrail Convenient to grab or hold. In this way, the open state of the finger of the hand and the thickness of the handrail substantially coincide with each other, and a stable grip state is obtained as a whole.
[0011]
In addition, when a handrail is attached to the side wall of the toilet along the flow line of the body in order to sit on a Western-style toilet and then assist the rising operation, the front side of the handrail, that is, the center of the body The part close to (around the waist of an adult) is thick, and it is arranged so that it becomes thinner as it goes away from the center. In this case, when the palm of the hand is positioned on the front side of the handrail, the handrail is thicker, and the body becomes stable rather than grasping the handrail with the fingers of the hand, and the defecation operation is facilitated. In addition, if you bring your hand in front of the middle of the handrail, that is, away from the center of the body, the body will naturally tilt forward, and the fingers of the hand will be half open and of moderate thickness. It is convenient to grip and tighten the middle of the handrail, and it is thicker before the handrail, so even if you do not tighten the fingertip along the outer periphery of the handrail, the hand will not slide on the handrail and the body will be easy You can pull up and stand up.
[0012]
In addition, a thin suspension bar is provided on the ceiling of a vehicle such as a route bus or a train, and the upper side is narrowed toward the toll box etc. Lowered vertically as a handrail, placed in the lateral direction in a thick state around the center of the body, and when used as a handrail, the ceiling suspension bar is thin, farthest from the center of the body, and located above the head It is easy to grasp, and since it is a thin handrail that is thin upward and thick downward, the hand does not slip from the handrail to attract the body, and the handrail is thick and supports lateral movement The handrail can be grabbed in a natural and convenient manner, and as a whole, different types of handrails are continuously arranged. It is especially safe among other vehicles.
[0013]
【Example】
The embodiment will be described with reference to the drawings. In FIGS. 1 and 2, T is a handrail, and is attached to the outer wall 23 of the door 21 frame 22 of the entrance 2 in the vertical direction. The vertical position of the handrail T is such that the middle of the handrail T is at the same height as the mounting position of the knob 24 of the door-21. For attaching the handrail T, the mounting seats 12 and 12 of the legs 11 and 11 protruding from the appropriate vertical positions of the handrail T may be applied to the wall 23 and fastened with screws (not shown) or the like.
The shape of the member 1 of the handrail T is long in the vertical direction in FIG. 2 and has an overall length of about 600 mm (the dimensions can be any number if necessary). The cross-sectional shape taken along line B and the cross-sectional shape taken along line C-C at the lower end are each shown in FIG. In FIG. 3, the AA cross section is substantially round like the cross section (3a), the outer diameter is small and the small diameter is s, and the actual BB cross section is round like the cross section (3b). It has a chamfered shape, its outer diameter is an intermediate middle diameter n, is actually about 35 mm, and the C-C cross section is substantially square like the cross section (3c), and one side has a large diameter m Actually, it is about 40 mm.
In this embodiment, the material of the member 1 is preferably wood or plastic, and the upper part has a round cross section in the shape, the lower part has a square cross section and the middle is finished into a continuous round chamfered cross section. When grasping T, the grasped position can be roughly confirmed with the hand H, giving the user a sense of security, and as the hand H moves to the lower part of the handrail T, the cross section of the member 1 becomes square. It becomes easy to grasp.
Of course, in the normal case, the upper and lower ends of the round shape are easy to manufacture, and there is no problem in use.
[0014]
4 and 5 illustrate the positional relationship between the human body M and the hand H and the handrail T. In FIG. 4, the person approaches the entrance 2 and grasps the handrail T with one hand H. When the door 21 is opened with the knob 24 of the door 21 with the hand H of the hand H, the hand H is usually in the middle position of the member 1 of the handrail T, that is, slightly above the center G of the body M. At the position, the finger of the hand H grips the member 1 in the middle B open state (usually the thickness of the handrail at this position is standard). However, as shown in FIG. 5, for the elderly and disabled persons, the position of the middle B of the member 1 of the handrail T is not necessarily grasped, but the upper end A position and the lower end C position are grasped. In the case of the upper end A position, the hand H is considerably higher than the center part G of the body M, and is far away. Thin and easy to grip. Further, in the case of the lower end C position, since the hand H is substantially the same height as the center part G of the body M, the finger of the hand H is open, so the thickness of the member 1 is the middle B position. It is thicker, easier to grasp, and easier to support the body M.
[0015]
FIG. 6, FIG. 7, FIG. 8, and FIG. 9 illustrate modified examples of the handrail T attached to the wall in the Western-style toilet. In FIG. 6, during the defecation sitting on the toilet 4, the handrail T disposed at a height close to the central portion G of the body M is used as the transverse member 116 whose thickness does not change, and the body continuously An inclined member 13f is disposed obliquely upward along the rising flow line of M. This portion is thick at the bottom and is thinned upward, and the upper end portion is formed by a thin parallel member 15. . Therefore, since the inclined member 13f of the handrail T is disposed along the flow line at the time of rising, and the hand M is pulled up by the hand H, the hand H is difficult to slip because the handrail T is an inclined member 13f that is thick at hand. .
[0016]
7 and 8, the handrail T is composed of a flat member 14 disposed horizontally, and the side portion of the toilet 4 is a horizontal member 14e and is seated on the toilet 4 (body M, hand H, etc.). Is not shown), while the elbow of the hand H is placed and the front taper member 14f is gripped, the body H is stable, and when standing up, if the tip of the taper member 14f is further gripped, it is easier to grip. The rise is facilitated and the rise is completed by pressing the tip member 14g.
The distal end portion 14g has a rounded distal end and is bent downward so as not to obstruct the movement of the body M in the reverse direction.
[0017]
FIG. 9 shows a modification of FIGS. 6 and 7, and is a handrail T disposed along the rising flow line of the person in the toilet. In the case of (9 a), the handrail T is vertical in front of the toilet 4. When installed in the direction, it is easy to start up on the spot. In the case of (9b), when the handrail T is attached in a shape that is continuous in the horizontal direction and the vertical direction, it is easy to stand up while moving the body M forward. In the case of (9c), attaching the handrail T horizontally helps to move the body M forward. These may be selected depending on the conditions in which the toilet is placed and the degree of disability. In addition to the toilet shown in FIG. 6, an optimal handrail system can be obtained by combining not only the toilet but also the bathroom, bedroom, corridor, room entrance, and the like according to the respective conditions.
[0018]
10 and 11 are armchairs K as application examples of FIGS. 7 and 8, and the armrests 14h and 14h of the armchairs K are deformations of the flat member 14 and are seated in FIG. The human body M is widened to the vicinity of the side of the center portion G, and gradually narrows toward the front, that is, narrows as the distance from the center portion G of the body M increases. When the hand H on the armrest 14h is located at the center G side position of the body M, the finger of the hand H is open and can hold a relaxed posture. When the arm is moved to the tip of the armrest 14h, the finger of the hand H moves away from the center G of the body M and becomes gripped, so that the narrow portion of the tip of the armrest 14h can be firmly gripped. M is stabilized and it is easy to move to the next operation. In particular, when the armchair K of the embodiment is also used as a portable toilet, it is effective for elderly people.
[0019]
Further, in the case of FIG. 12, the long member 1 having a cross-section convenient for being clamped with the hand H continuously disposed along the movement line of the person in the vehicle 5 of the route bus or the route train. In the handrail T, the suspension bar 15a attached to the ceiling above the human body in a suspended manner is naturally higher than the head of the body M. A thin type parallel member 15 may be used. Hereinafter, the parallel member 15 refers to the long member 1 in which one outer shape and the other outer shape are parallel to each other in a side view of the outer appearance regardless of the cross-sectional shape being round or square. Furthermore, when it moves continuously to the handrail T member 1 in the vertical direction, the upper end portion thereof has the same diameter as the suspension rod 15a and becomes thicker as it goes downward, and the center portion G of the human body M is the largest. The lower part may be a parallel member 15 having the same diameter up to the mounting seat 12 on the floor at the lower end.
When the horizontal member 16 is provided by branching from the position with the largest diameter of the handrail T member 1 in the vertical direction , that is, around the center portion G of the human body M, the finger of the hand H is open. It is easy to grab a thick object and is good for supporting the body M with the flat surface of the hand H. While supporting the body M around the center G of the body M with the horizontal member 16, the travel fee is settled with the hand H and moved. You can also. Finally, the flat member 14 and the like may be disposed downward toward the outlet.
This method can be selected according to the nature of the exit.
For example, in the case of FIG. 13, when the handrail T is arranged vertically when a person gets on and off, it is useful to draw the body M through the handrail T.
[0020]
Next, as shown in FIG. 14, in the case of the handrail T provided on the long staircase 6 or the like according to the movement line of the person, if the lower side is thick and the upper side is thin, it does not continue long. Therefore, the handrail T may be set as the connection handrail 17a... And continuously arranged by a known technique such as insertion at regular intervals.
[0021]
15, 16, and 17 relate to the outer peripheral shape of the member 1 of the handrail T, and the outer shape 18 of the member 1 in FIG. 15 has a corrugated outer shape 18 a, and the upper end portion A as a whole. Is a small diameter s, and the lower end C is a large diameter m. In this case as well, the outer surface is a continuous outer surface, and the hand H extends downward from the concave / convex outer shape 18a of the member 1 together with the ease of gripping the member 1. As you move (not shown), your fingertips will not slide and you will get good results.
[0022]
In the case of FIG. 16, the parallel member 15 of the handrail T is conventional, and when it is desired to form the outer shape 18 of the handrail T as a large large diameter m at the lower end C and a small small diameter s at the upper end A, If a mounting member 7 such as a commercially available adhesive tape is wound around and mounted, a tape outer shape 18b having a desired shape can be formed. In this case, an optimum outer shape can be provided at the site, which is convenient.
In the case of FIG. 17, if the mounting member 7 such as sponge is wound around the parallel member 15 of the handrail T, a sponge outer shape 18 c is formed, and a large diameter m at the lower end C and a small small diameter at the upper end A. By forming into s, a sponge outer shape 18c having a desired shape is obtained. In this case, since the sponge outer shape 18c is a sponge, it has elasticity, is easy to grasp, and does not hurt the hand H (not shown).
The mounting member 7 is not limited to adhesive tape and sponge, but may be any material that is convenient for the surface of the handrail 1, such as cloth, rubber, wood, plastic, or metal.
[0023]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0024]
According to conventional experience, a member 1 having a cross-section convenient for hand-clamping is arranged in a vertical direction in accordance with a human body M, and the lower side of the cross-section of the member 1 is set to a large diameter m. Since the diameter s is reduced to a small diameter s, it matches the natural movement of the finger of the human hand H, and the nature of the hand H being gripped as it moves to the upper position with respect to the central part G of the body M, as in the past. In the case of the same diameter of the top and bottom of the handrail, such as a handrail made of a parallel member 15, the middle of the handrail can be gripped in line with the natural opening of the finger of the hand H, but the upper is against the opening of the finger. The outer diameter of the handrail is too thick, and the lower part is not too thin for the finger opening. As a result, no matter what position of the handrail T is gripped, the handrail T with the optimum thickness is provided. it can.
[0025]
Further, since the change in the upper and lower thickness of the handrail T outer diameter is continuously formed, the hand H holding the position where the handrail T is located can be simply slid downward without tightening the finger. The result is the same as increasing the grip strength of the hand H by increasing the diameter, which is convenient for the elderly and the handicapped who have weak grip strength.
[0026]
A longitudinal member 1 having a cross section convenient for clamping with a hand H is arranged in a lateral direction in accordance with a human body M, and a large diameter m is located near the center position G of the body M of the outer diameter of the cross section of the member 1. In addition, since the diameter of the body M is decreased as the distance from the center G of the body M increases, the hand H is placed on the body H to grasp the handrail T. The handrail T is easily gripped as it moves away from the center G, and the handrail T (in the vicinity of the center G of the body M) is thicker, and the handrail T is thicker. It is easy to support the body M with the palm of the hand H. Moreover, since the outer diameter of the handrail T is continuously changed, it is the same as the gripping force of the hand H is strengthened only by pulling the hand H toward the front side without tightening the finger once gripped. The body M is easy to draw.
[0027]
The member 1 of the handrail T is disposed in accordance with the direction of movement of the body M during the movement operation, and the diameter near the center portion G of the body M before the movement operation is set to the large diameter m, and as the distance from the body M center portion G decreases Since the member 1 is formed, especially when moving from a stationary operation to which a force is applied to a moving operation, a change in the outer diameter of the handrail effectively works to grasp the handrail, and the body M can be stabilized.
[0028]
Since the member 1 of the handrail T is a flat member 14 and is formed so as to be wider near the center portion G of the body M and away from the center portion G of the body M, the flat member 14 having a wide width when the body M is stationary. It is easy to support the body M, and it is easy to grasp the narrow flat member 14 during movement.
[0029]
By attaching the mounting member 7 to the outer periphery of the conventional parallel member 15 and changing the outer diameter of the handrail T, the handrail is easily replaced with a thick hand and a thin tip without replacing the handrail. Handrail T can be provided, and in addition, the outer diameter of the handrail T can be obtained in the optimum shape according to the site, that is, the degree of the elderly or the handicapped, and the material used is also the right material at the right place. Thus, the handrail T with higher functionality can be provided.
[0030]
The handrail T is disposed along the movement flow line of the body M, and the conventional parallel member 15, the member 1 having a thick hand side and a thin tip side, a flat member 14, Since the mounting member 7 and the like are selected and continuously combined, it is possible to provide the handrail T suitable for the specific operation during the movement, but the handrail T is continuous. It can be moved and is safe.
