Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a handrail device and a handrail used for the handrail device.

[0002]

2. Description of the Related Art As a handrail device capable of vertically rotating a handrail body, one described in Japanese Patent Application Laid-Open No. 9-209535 is known. In this conventional example, the handrail device has a mounting base fixed to an installation base such as a wall surface, and a handrail body whose base end is rotatably supported in a vertical direction with respect to the mounting base. The handrail body used in the above can be rotated to the vertical rotation posture and retracted.

[0003]

However, the above-mentioned prior art has the following disadvantages. That is, the handrail body is held in a horizontal rotation posture by its own weight, and the upward rotation is not prohibited.For example, when the user tries to stand up by pulling the handrail body, the handrail body also rotates upward. It does not provide support and is inconvenient to use. In addition, the holding in the vertical rotation posture is performed by a locking means such as a roller catcher. However, since the locking force of the locking means is not high, the body is grasped by the handrail body in the vertical rotation posture in an immediate case. The function as a handrail is not fulfilled even if it tries to support. Furthermore, since only the horizontal rotation posture and the vertical rotation posture can be selected for the handrail body, it is necessary to lift the handrail body to the vertical rotation posture without fail when trying to retract the handrail body to the retracted position. However, although the height of the elbow differs depending on the user, the height in the horizontal posture is uniquely determined, so that the usability is poor.

In addition, in the above-mentioned conventional handrail body, since the distance between the upper and lower hand portions of the handrail bar is constant from the tip to the pivotal connection portion to the mounting base, the handrail body is changed from the horizontal posture to the vertical posture. Due to the large protrusion of the base end when rotated, the space of the mounting part, especially the protrusion dimension from the wall, becomes large, the operating range of the user is narrowed, and not only is it inconvenient to use, but also good appearance Absent.

The present invention has been made to solve the above-mentioned drawbacks, and has as its object to provide a handrail device which is easy to use. Still another object of the present invention is to provide a handrail body that can improve not only convenience but also appearance.

[0006]

According to the present invention, there is provided a handrail body 3 having a base end pivotally supported on a base 2 attached to an installation base 1 such as a wall so as to be vertically rotatable. The handrail body 3 is achieved by providing a handrail device in which a horizontal rotation posture is held by a stopper 5 that can be released by an operation unit 4 disposed at the center of the handrail body 3 and the upward rotation operation is restricted. .

The handrail body 3 is formed by pivotally supporting the base end of the handrail body 3 to the base 2 so as to be vertically rotatable.
It can take a horizontal rotation posture during use. The horizontal rotation posture is held by the stopper 5, and the upward rotation is allowed only when the stopper 5 is released by operating the operation unit 4 disposed at the center of the handrail body 3. Therefore, in the present invention, even if the handrail body 3 is pulled upward to support the body, the body does not rotate upward, so that the usability is good and the safety is high.

The invention according to claim 2 is a handrail body 3 whose base end is vertically rotatably sandwiched between a pair of vertical wing pieces 6, 6 projecting from a mounting base 2 to an installation base 1 such as a wall surface. A stopper 5 is provided at the base end of the handrail body 3 so as to be able to advance and retreat in the orthogonal direction from a surface facing the vertical wing piece 6 by an operation unit 4 arranged at the center of the handrail body 3. This is a handrail device capable of holding the handrail body 3 at a predetermined rotation angle posture by fitting into one of a plurality of fitting recesses 7 provided on the wing piece 6.

The base end of the handrail body 3 is sandwiched between a pair of vertical wing pieces 6 of the mounting base 2 and is pivotally supported by the vertical wing pieces 6 so as to be vertically rotatable. The rotation posture of the handrail body 3 is maintained by engaging the stopper 5 with the fitting concave portion 7 of the vertical wing 6, and can be shifted to another rotation posture by releasing the stopper 5.

Therefore, in the present invention, in both the horizontal rotation posture during use and the vertical rotation posture during evacuation, the rotation posture is maintained by the stopper 5 which advances and retreats in the orthogonal direction from the surface facing the vertical wing piece 6. As described above, in the horizontal rotation posture, the handrail body 3 is not rotated upward even if the handrail body 3 is pulled upward to support the body. The handrail body 3 does not rotate carelessly.

It is sufficient if the handrail body 3 can be maintained at least in a horizontal posture and a vertical posture. However, as in the invention according to claim 3, the handrail body 3 has an intermediate rotation posture between the horizontal rotation posture and the vertical rotation posture along the installation base 1. If it can be stopped, not only can the height of the elbow contact portion be adjusted, but also an appropriate rotation position can be selected after use, and the handrail body 3 does not necessarily reach the vertical rotation posture.
There is no need to rotate.

Further, if the damper 8 is provided as in the invention according to the fourth aspect, the handrail body 3 can be prevented from dropping sharply. The use of the damper 8 is particularly useful when the operation unit 4 is operated by grasping the grip 4a of the operation unit 4 as shown in FIG. That is, by providing the grip portion 4a, the operation portion 4
Although the operability of the handrail body is improved, the weight of the handrail body 3 is less likely to be supported than when the operation on the operation unit 4 is performed while the handrail rod 9 of the handrail body 3 is gripped. When the damper 8 is provided, the fear of the user can be removed, and it is not necessary to support the weight of the handrail body 3 in an unstable supporting state.

According to a fifth aspect of the present invention, there is provided a handrail body 3 having a handrail rod 9 bent in a U-shape and used by pivotally supporting a base end of the mounting base 2 such as a wall so as to be vertically rotatable. So,
The distance between the upper and lower rod portions 9a, 9b of the handrail rod 9 is a handrail body handrail body that is narrow at the base end.

The handrail body 3 is formed in a U-shape, and the interval between the upper and lower rod portions 9a and 9b is smaller at the base end than at the tip. By narrowing the interval between the upper and lower rod portions 9a and 9b at the base end, the radius of rotation at the base end is reduced, and when the pivotal support portion of the handrail body 3 is covered with, for example, a bracket plate, The amount of protrusion of the bracket plate from the wall surface or the like can be reduced, and the overall appearance can be reduced.
