Description

The present invention relates to a handrail and its installation structure. More specifically, even when the handrail is gripped at a position and depth other than a predetermined position and a predetermined depth, the handrail can be securely gripped without slipping and its installation. Concerning structure.

Many conventional handrails have a pipe shape with a circular outer periphery. Such a bar-shaped handrail whose outer periphery is almost a perfect circle has no directivity in the circumferential direction, and therefore has an advantage that it is easy to grip even when a hand is placed on the handrail from any direction. However, on the other hand, there is a drawback that the outer peripheral surface is slippery, and the hand held to support the weight at the time of changing the posture such as from the standing position to the sitting position or from the sitting position to the standing position. There is a danger of slipping away from the handrail and falling and injury due to the reaction.

In order to solve such a problem, when the outer periphery of the handrail is formed with a continuous curve, a handrail in which a recess for hooking a fingertip of a finger other than the thumb is formed at a predetermined portion of the outer periphery, There has been proposed a handrail or the like in which a recessed portion is formed in a portion where the fingertip of a finger is located. With such a configuration, when the handrail is gripped, the fingertips of fingers other than the thumb are caught in the recesses, or the fingertips of the thumb and other fingers are positioned in the respective recesses so that all the fingertips are in the recesses. It is possible to expect the effect that it can be securely gripped without catching and slipping the handrail.

However, the handrail described in the above-mentioned known document such as JP 2000-240249A is
It can be said that the above function can be exhibited only when the handrail is securely grasped at a predetermined position of the hand and at a predetermined depth. Here, gripping the handrail at a predetermined position and a predetermined depth of the hand means that the handrail is positioned in a direction in which the handrail passes between the thumb and the index finger and comes out to the little finger side, and the palm of the hand is attached on the handrail. And so that the thumb and the other four fingers are located in the respective engaging recesses,
It is defined as gripping the handrail in a state where the palm and the upper surface of the handrail are in close contact.

However, for example, when trying to change the posture from a sitting position or from a wheelchair to a standing position, the handrail installation height is above the shoulder position, so The lower four fingers are put on the little finger side, the other four fingers are brought into contact with the front side and the upper side of the handrail, and the hand is held in this state. That is, the handrail cannot be gripped at a predetermined position and a predetermined depth.

As a result, the fingertips of the thumb and other fingers grip the handrail in a state where the thumb and the other fingertip do not fit in the recesses for engagement formed at the positions of the predetermined center angles on the outer periphery of the handrail. For this reason, the fingertip is gripped without being caught with the outer periphery of the handrail, and the same problem as in the case of the round bar described above occurs that the gripped hand slides off the handrail. Such a problem may occur even when the hand is small relative to the outer diameter of the handrail or when the handrail is shallowly gripped only by the fingertip.

The present invention is intended to solve the conventional problems as described above, and even when the handrail cannot be gripped at a predetermined position and a predetermined depth of the hand, It is an object of the present invention to provide a handrail that can be easily gripped by combining, and that can be securely gripped even by a low grip force person such as an elderly person, and an installation structure thereof.

In order to achieve the above object, the first solution of the present invention is a handrail of a desired length in which the outer periphery is formed of a continuous straight line, and grips the handrail from above. The little finger side
When formed with a first hanging surface that hangs substantially perpendicularly from the upper surface via a first descending inclined surface and a first inner inclined surface that is inclined inwardly from the first hanging surface, A horizontal V-shape comprising a second hanging surface that hangs substantially vertically from the upper surface through a second descending inclined surface, and an inner inclined surface portion and an outer inclined surface portion following the second hanging surface. Each of the surfaces is formed as a handrail, and a connecting portion between adjacent surfaces of the surfaces protrudes as a ridge line in the longitudinal direction.

The second solving means of the present invention is characterized in that the portion of the first inner inclined surface on the little finger side is formed by a second inner inclined surface and a third inner inclined surface. And the third solving means of the present invention is such that at least one end side of the handrail is surrounded by an outer inclined surface inclined in the axial direction from the periphery and an outer edge of the outer inclined surface. The handrail is characterized in that it has a configuration in which a drooping bottom surface having a rectangular shape in front view is formed.

Further, the fourth solving means of the present invention comprises a structure in which the handrail according to claim 1, 2 or 3 having a total length of 30 to 40 cm is installed on a wall surface or the like alone or at a predetermined interval. This is a handrail installation structure characterized by the above.

Effects and effects of the invention

As described above, the first solving means has a configuration in which, when the outer periphery is entirely formed from a plane, the connecting portion between each plane and the plane protrudes as a ridge line extending in the longitudinal direction of the handrail body. Therefore, the handrail was gripped at an angle different from a predetermined angle with respect to the longitudinal direction of the handrail, as well as when grasping deeply with the upper surface of the handrail being in close contact with the palm. Even in this case, the palm and the belly of the finger are always in contact with a plurality of ridgelines projecting outward from the surface and a plurality of planes defined by the ridgelines. And it will be in the state where a ridgeline will bite into a hand by grasping a hand strongly, and friction resistance and contact resistance will improve.

Further, the second solution means that the little finger side is formed by the second inwardly inclined surface and the third inwardly inclined surface, respectively, so that the outer periphery on the little finger side has a handrail at a predetermined position and a predetermined depth. The shape of the four fingers on the little finger side is the second inwardly inclined surface, the third inwardly inclined surface, and both inwardly inclined surfaces even when gripped with a relatively weak force. Contact with the ridge line interposed therebetween improves the frictional resistance and contact resistance between the gripping hand and the outer peripheral surface of the handrail.

And the third solving means, that is, the front surface surrounded by at least one end surface of the handrail with the outer inclined surface inclined from the outer periphery toward the axial direction and the outer edge of the outer inclined surface The structure formed by forming a rectangular bottom end surface makes it easier for standing pedestrians and wheelchair users to grip the end of the handrail, and can be moved in the direction of travel by hooking with the index finger, middle finger, ring finger, etc. You can gain momentum.

In addition, the fourth problem solving means, that is, the doorway according to claim 1, wherein the total length is 30 to 40 cm, is installed on a single wall or a plurality of wall surfaces at a predetermined interval. It can be installed even in places where it was not possible to install because of its short width. Alternatively, even if it is a place where a continuous recess for embedding the handrail cannot be formed because the dimension between the columns is fixed, a recess with a width that can embed a handrail alone is formed on the wall between the columns. Since handrails can be discontinuously installed in recesses formed on the wall at a predetermined interval, for example, 25 to 35 cm, an effective handrail when moving for standing pedestrians and wheelchair users It becomes.

  Hereinafter, the present invention will be described in detail based on the embodiment shown in FIGS.

One end of each of the outer inclined surfaces 11a to 11d is composed of four corner portions of the rectangular hanging lower end surface 12 and end ridge lines 13a to 13d that are continuous. In the figure, 1
Reference numeral 4 denotes an attachment base formed at the lower part of the handrail main body 1.

3 to 5 show the attachment state and use state of the handrail A _{1 according} to the first embodiment.
As shown in FIGS. 3 and 4, the base 15 a of the support 15 is fixed to the wall surface W, and the attachment base 14 at the center of the handrail A ₁ is fixed to the receiving portion 15 b formed at the tip of the support 15. Thus, the handrail A ₁ is installed on the wall surface W having a predetermined height from the floor surface. Then, if necessary, as illustrated in Figure 5, the handrail A ₁ of the same structure at a handrail A ₁ by a predetermined distance S mounted in the same way as above, discontinuously in the wall surface W plurality Install one.

As shown in FIG. 3, when the handrail A ₁ thus installed is gripped at a predetermined position and a predetermined depth of the left hand M, that is, (1) the handrail A ₁ is between the thumb and the index finger. (2) A palm is attached on the upper surface 2 of the handrail A ₁ , located in the direction of passing through to the little finger side, (3)
Fingertip of the thumb is positioned at the lateral V-shaped plane 8, (4) the other four fingers of the little finger side of the hand rail A ₁ 1 downwardly inclined surface 3, the first hanging surface 4, the first inner inclined Located on face 5 and (5)

When the handrail A ₁ is gripped with the left hand M in a state where the above conditions (1) to (5) are satisfied, the palm is the upper surface of the handrail A ₁ , the base of the thumb and the thumb belly are the second descending inclined surface 6. , The second drooping surface 7 and the inwardly inclined surface portions 8a and 8b and the ridgelines 9d, 9e, 9f, and 9g that define each plane. On the other side of the little finger, the base of the other four fingers excluding the thumb and the belly of the finger define each plane and each plane of the first descending inclined surface 3, the first hanging surface 4, and the first inwardly inclined surface 5. Ridge lines 9a, 9
b and 9c come into contact with each other, and these ridges engage with the palm of the hand, the belly of the finger, and the fingertip, thereby increasing the slip resistance and preventing the hand from falling off.

However, there is a case where the handrail cannot be gripped in a good state that satisfies the above conditions (1) to (5). In this case, although the fingertip of the thumb is a point not located within the lateral V-shaped surface 8 common, and if the further palm is holding deep in a state of close contact with the outer peripheral surface of the handrail A _1, palm handrail A ₁ In some cases, the finger is held lightly with the belly and fingertips of the finger while floating from the outer peripheral surface of the finger. However, the palm, the fingertips, and the belly of the fingers when they are grasped deeply, and the fingertips and the belly of the fingers when they are grasped shallowly define the planes 2 to 8 and the planes located nearby. It contacts in the state which straddled each ridgeline 9a-9g. As a result, each plane is brought into contact with the ridgeline, the slip resistance is further increased, and further hand slippage is prevented.

FIG. 5 is a view showing a state in which a plurality of handrails A ₁ and A ₁ are installed on the wall surface W via the support 15 in a discontinuous state at a predetermined interval S. In general, when a standing person or a wheelchair user uses a handrail, the hand held is once separated from the handrail, and a distance in the traveling direction, for example, 25 to 25
It was observed that after moving the hand by 35 cm, it was moved to the target location by repeating the operation of grasping the handrail installed nearby again.

Therefore, in the present invention, the protruding portion 10 having a shape that is easy to grip and not slip easily at both ends of the handrail A _1.
If the structure is made of, the installation that can be used by skipping the hand to the next handrail A ₁ installed at a predetermined interval S by pushing the body in the direction of travel with the hand grasping the protrusion 10 It is structured. In addition, as a reason other than the above, the handrail A ₁ is discontinuously attached at a predetermined interval S. In the case of unit care, there is a living room in the center of each living room group.
Handrails are used only when entering and leaving the room, and there is little or little parallel movement with respect to the corridor.

Thus, when the protruding portion 10 having the above structure formed at the end of the handrail A ₁ is used, FIG.
