Description

The present invention relates to handrails, handrail devices and handrail systems suitable for use in the fields of long-term care and welfare.

In order to ensure the safety of elderly people and supporters requiring nursing care when walking on their own at home, nursing homes, hospitals, etc., handrails are attached to the walls of corridors and stairs, or in corridors and entrances. Stationary handrail devices and handrail systems are installed.

Conventional handrails are generally those in which a plurality of brackets are attached to a wall surface and a rod-shaped member which is a handrail body is fixed to these brackets (see, for example, Patent Document 1).

Further, as a handrail device, for example, a device including a base portion, a strut portion erected on the base portion, and a handrail supported by the strut portion is known (for example, Patent Document 2). 3, 3).

Further, as a handrail system, a system in which a plurality of handrail devices as described above are prepared and a handrail is erected between these handrail devices is known. As an example, the first base plate, the second base plate, the first strut attached to the first base plate, the second strut attached to the second base plate, and the first strut attached to the upper end of the first strut. A hinge, a first handrail mounting portion attached so that the angle can be changed with respect to the first strut via the first strut, a second hinge attached to the upper end portion of the second strut, and a second hinge. A device having a second handrail mounting portion that is attached so that the angle can be changed with respect to the second support column and a first handrail that is bridged between the first handrail mounting portion and the second handrail mounting portion. (See, for example, Patent Document 4). Further, as another example, a standing motion assisting tool in which a plurality of cross rails are connected in the vertical direction between a pair of columns facing each other in parallel, and the lower end of the columns is supported almost perpendicularly to the base plate. It is made by connecting a pair of horizontal handrails that face each other almost parallel to the top and bottom, and a handrail for lateral movement, which is made by connecting multiple vertical rails, so that they can be used in common. One of the columns of the stand-up operation assisting tool and one of the vertical rails of the handrail for lateral movement were connected in a parallel state and in a rotatable state by a connecting tool having a configuration in which two socket portions were arranged in parallel.

By the way, elderly people, long-term care supporters, etc. tend to concentrate their attention exclusively on their feet because they are anxious about their feet when walking using handrails. For this reason, the hand is sparser, and it is often the case that the position of the handrail is not known. Therefore, it may not be noticed even though the hand reaches the end of the handrail as the person walks. Here, elderly people and supporters requiring nursing care often leave their weight on the handrail while grasping the handrail, so if they continue walking without noticing that the hand has reached the end of the handrail, Inevitably, the hand will come off the end of the handrail, and as a result, it is assumed that the hand will fall violently and suffer serious injuries such as fractures. Also, for example, even if you continue from a horizontal handrail to a downhill handrail, if you continue walking without noticing that the horizontal handrail will end, you will suddenly go down contrary to your expectation that the horizontal handrail will still continue. Since the hand moves to the sloped handrail, it is feared that the sudden change will cause the handrail to fail to be grasped, leading to a fall accident as described above.

In order to prevent such a fall accident, it is necessary to inform the elderly and the long-term care supporter by some means that the hand has reached the end of the handrail. However, in the above-mentioned conventional handrails, handrail devices, and handrail systems, since all the handrails have a uniform shape over the entire length, elderly people, care-requiring supporters, etc. can determine where the end of the handrail is. Can't tell. Therefore, the above-mentioned conventional technique cannot be expected to prevent a fall accident.

The present invention has been made to solve the above-mentioned problems, and informs an elderly person walking along the handrail, a care-requiring supporter, or the like that the hand has reached the end of the handrail, and temporarily stops. This is an attempt to provide a handrail, a handrail device, and a handrail system that can prevent a fall accident caused by a hand slipping off the handrail.

In order to solve the above problem, the handrail according to the present invention is said to reach both ends of the handrail body or one end of the handrail body, and the hand of the user reaches the end of the handrail body. It is characterized by having a warning section to call attention.

In the handrail, the caution portion is set to a height that bulges from the upper side of the handrail main body and the bulging height can prevent the user's hand from slipping down from the end portion of the handrail main body. It is good to have.

Further, the handrail device according to the present invention includes a base portion, a strut portion erected on the base portion, and a handrail supported by the strut portion, and the handrail is provided with the above-mentioned caution portion as a handrail. It is characterized in that it is a handrail provided at both ends of the main body or at either end.

Further, the handrail system according to the present invention is characterized in that it is composed of a plurality of the above-mentioned handrail devices and a connecting handrail erected between the handrails of these handrail devices.

Further, the handrail system according to the present invention includes a plurality of handrail devices including a base portion, a strut portion erected on the base portion, and a handrail supported by the strut portion, and the handrail device described above. It is composed of a connecting handrail erected between the handrails, and the connecting handrail is characterized in that the above-mentioned alerting portion is a handrail provided at both ends or one end of the handrail main body. It is something to do.

In the above handrails, handrail devices, and handrail systems, note to the user at both ends of the handrail body or at either end that his or her hand reaches the end of the handrail body. Since a warning section is provided to call attention, it is possible to directly notify elderly people walking along the handrail and supporters requiring nursing care that the hand has reached the end of the handrail through the feel of the hand. You can make them stop there. As a result, the elderly and the long-term care supporter can surely grasp the position of their own hands, so that the hands do not slip off from the end of the handrail.

According to the present invention, an elderly person walking along a handrail, a care-requiring supporter, or the like is notified that the hand has reached the end of the handrail and is made to stop once, whereby the hand slides off the handrail. It is possible to prevent a fall accident caused by the above.

It is a perspective view which shows one Embodiment of the handrail system of this invention. It is a partially enlarged front view of the handrail system shown in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The components common to each of the following embodiments are designated by the same reference numerals.

-Handrail-
FIG. 1 is a schematic front view showing an embodiment of a handrail according to the present invention. The handrail 1 includes a handrail main body 2 and warning portions 3 and 3 provided at both ends of the handrail main body 2, and is attached to a wall surface W of a building via brackets 4 and 4.

As the handrail main body 2, a conventionally well-known one can be adopted, and the material thereof does not matter. From the viewpoint of ease of grip, for example, one having a rounded shape such as a circular cross section or an elliptical cross section is suitable. The mounting height on the wall surface W may be appropriately determined according to the physique of the user, the walking posture, and the like. Further, in a nursing care facility used by a large number of people, for example, a plurality of handrails 1 may be displaced in the vertical direction and attached to the wall surface W.

The caution unit 3 is for alerting the elderly, the care-requiring supporter, and other users that their hands have reached the end of the handrail body 2. More specifically, the user is informed that the end of the handrail body 2 has been reached, the walking operation is temporarily stopped at the end of the handrail body 2, and the next operation, for example, a door knob or lever, is performed. The purpose is to allow people to calmly move to a different movement from the conventional walking movement, such as grabbing and opening the door, moving to a wheelchair, or switching to another auxiliary tool. That is, if there is no warning unit 3, the user has to pay attention to move to the next operation as described above, and the state at hand, that is, the hand has reached the end of the handrail body 2. Without noticing it, he thinks that the handrail 1 is still continuing and continues walking. Then, since the handrail 1 is no longer continued, the hand of the user who thinks that the handrail 1 is still present will grab the sky, and as a result, the user will invert greatly by the amount of weight applied to the handrail 1. Will end up. In the worst case, there is a risk of serious injury such as a broken bone. However, when the warning unit 3 is located at the end of the handrail body 2, the user notices that the handrail 1 does not continue anymore, and stops there to check the hand, so that the above-mentioned fall accident does not occur. The user will be able to calm down and safely move on to the next action.

Further, the caution unit 3 is for alerting the user that his / her hand has reached the end of the handrail body 2 as described above, and surprises the user. It must not be in such a form. That is, since the user puts his / her weight on the handrail 1 and gives his / her hand to the handrail main body 2 while paying attention to his / her feet, the attention alerting unit 3 feels extremely different from the handrail main body 2. If this is the case, as soon as the user touches such a warning unit 3, he / she will be surprised at the change in the feeling and will take his / her hand away from the handrail 1, and as a result, there is a possibility that a fall accident may occur. .. Therefore, as a form of the alert portion 3, as shown in FIG. 1, a rising portion 30 that rises from the upper side of the handrail main body 2 by drawing a gentle curved surface and a rounded top portion 31 that is smoothly continuous from the rising portion 30. It is composed of a bulging portion 32 composed of the bulging portion 32 and a vertical surface portion 33 smoothly continuous from the top portion 31 of the bulging portion 32. Further, the height of the warning portion 3 as described above, that is, the height of the bulging portion 32 can prevent the user's hand from slipping off from the end of the handrail main body 2, and the user feels sudden discomfort. It is said that the height does not make you remember. Specifically, the height of the bulging portion 32 (the height from the upper edge of the handrail body 2 to the apex of the bulging portion 32) is preferably 6.5 mm or more and 12.5 mm or less. If the height is less than 6.5 mm, even if the user touches the alert unit 3, the user may not recognize it as the alert unit 3, and the height is 12.5 mm. If the height exceeds the above, the user may feel a sudden sense of discomfort, and as a result, the user may be surprised to move his / her hand away from the handrail 1 and cause a fall accident. When the alerting portion 3 has such a form, the user is not surprised even if the alerting portion 3 is touched by the handrail body 2, and the user grasps the bulging portion 32 without resistance. be able to. As a result, the user notices that his / her hand has reached the end of the handrail 1, understands that the handrail 1 will not continue in the future, and stops here to check the hand. Then, after understanding what kind of action you will move to next, calm down and start the next action. Therefore, no fall accident occurs.

Further, in the present embodiment, the alerting portion 3 is formed of a separate member from the handrail main body 2 and is externally fitted and fixed to both ends of the handrail main body 2. As the material of the caution portion 3, synthetic resin is suitable from the viewpoint of moldability, but both end portions of the handrail main body 2 itself may be processed into the above-mentioned form. That is, when processing both ends of the handrail body 2, for example, if the handrail body 2 is made of wood, it is assumed that the attention-calling portions 3 are formed at both ends of the handrail body 2 by cutting. Further, when the handrail main body 2 is a metal pipe, it is assumed that the attention-calling portion 3 is formed by performing a molding process so as to bulge both ends thereof, for example. Here, when the attention alerting portion 3 is externally fitted and fixed to the end portion of the handrail main body 2, the difference between the outer diameter of the swallowing portion 34, which is the starting end of the rising portion 30 of the alerting portion 3, and the outer diameter of the handrail main body 2 is large. It is desirable to reduce the wall thickness of the swallowing portion 34 so as to be as small as possible. Alternatively, the outer diameter of the swallowing portion 34 of the alerting portion 3 is made equal to the outer diameter of the handrail main body 2, and the outer peripheral surface of the end portion of the handrail main body 2 is scraped by the thickness of the swallowing portion 34 to make the alerting portion 3. The surface of the handrail main body 2 and the swallowing portion 34 may be smoothly connected to each other when the handrail main body 2 is fitted onto the end portion.

In the present embodiment, the attention alerting portions 3 are provided at both ends of the handrail main body 2, but when the user's attention is alerted only to one end portion, only one end portion is provided. It may be provided.
