[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the movable handrail according to the present invention will be described with reference to FIGS.

FIG. 1 shows a movable handrail according to an embodiment of the present invention. In this movable handrail, the handrail main body 1 can be rotated from the horizontal use position shown by the solid line in FIG. 1 to the storage position along the wall surface A shown in FIG. It is configured so that it can be pivotally attached to and pivoted in the vertical direction.

As shown in FIGS. 1 and 3, the handrail main body 1 fixes a base end portion of a supporting rod 2 having a substantially U-shaped cross section to a rotary base body 3, while the rotary base body 3 is provided with a rotary shaft 4. With this, the support rod 2 is rotatably mounted in the gap of the bracket 5, and the support rod 2 is rotated about the rotation shaft 4. The movement of the rotating base body is restricted between the locking stopper 13 and the storage stopper 14, and the rotation range is about 90 degrees between the horizontal state and the storage state. That is, the rotating base body in the horizontal state abuts on the storage stopper 14, and the rotating base body in the vertical state abuts on the locking stopper 13, so that the contact points cannot be exceeded.
In addition, a rubber cushion (not shown) is interposed at the contact point so that the impact at the time of contact is mitigated.

When the support rod 2 is inverted and put in the retracted state, the rotation base 3 in that posture has a projection 17 attached to the tip thereof like a roller catch or a magnet catch provided on the back surface of the storage stopper 14. The locking device 16 is engaged, and the inverted state is maintained. When the support rod 2 of the handrail main body 1 is extended horizontally, a lateral force is applied to the support rod 2 to release the engagement of the locking tool 16.

In the bracket 5, a pair of plates 15 formed by bending a mounting portion to a wall surface are opposed to each other with a space therebetween so that the rotating base 3 can rotate, and together with the storage stopper 14 and the locking stopper 13. It is configured as one. A hole for supporting the rotary shaft 4 is formed in the middle part of the bracket 5, and the rotating base 3 is pivotally attached to the hole so that the rotating base 3 can rotate within the gap of the bracket 5.

Next, a description will be given of the braking mechanism 12 for limiting the rotation speed of the rotation base body 3 which freely rotates in the range of about 90 degrees between the locking stopper 13 and the storage stopper 14. As shown in FIGS. 1 and 3, the braking mechanism includes a first link 6 pivotally attached to a fulcrum 9 on the plate 15 side,
And the second link 7 pivotally attached to the fulcrum 10 on the rotating base 3 side.
A stay damper 20 provided between the contact point 8 and the wall surface fulcrum 11 is provided to limit the displacement speed of the contact point 8, and the contact point is displaced in accordance with the movement of the rotating base 3. The displacement speed of No. 8 is resisted by a stay damper against the force to rotate freely, and braking is applied so as to obtain a desired set speed.

The braking mechanism 12 has a structure in which a stay damper is provided between the fulcrum 10 fixed to the rotary base and the wall fulcrum 11 to limit the displacement speed of the fulcrum 10 in accordance with the movement of the rotary base 3. With the stay damper, the displacement speed of the fulcrum 10 which is displaced can be resisted against the force to freely rotate and the braking can be applied so as to obtain a desired set speed. The stay damper 20 has two chambers C and D formed by a piston 22 inside a cylinder 21 as shown in FIG. 4, for example.
It is preferable to use a gas spring in which the buffer solution or gas in one chamber is moved to the other chamber while being adjusted by the orifice 27 so as to exert a strong repulsive force in the extending direction of the piston rod 23. 24 is an oil seal,
Reference numeral 25 is a free piston, and 26 is a gas chamber into which nitrogen gas is press-fitted to constantly pressurize the chambers C and D. In addition, it goes without saying that a mechanical spring or a combination of a spring and a buffer solution or gas can be substituted for this gas spring as long as it has the above-mentioned function.

Further, another embodiment of the braking mechanism will be described. In this braking mechanism, as shown in FIG. 5, a rotary shaft is directly connected to the rotary base body 3, and a rotary damper 31 is provided between the plate and the rotary shaft extending outward from the plate 15.
Braking is applied to the rotating base body 3 which is about to be freely rotated by the rotary damper. The rotary damper, for example, directly connects the friction disc 31 to the rotating base body 3,
A brake 32, which works strongly in one direction and weakly in the opposite direction by a wedge action, is brought into contact with this, so that the rotary base body 3 itself can directly and freely resist the force to freely rotate and achieve a desired set speed. Apply braking. In addition to this, the rotary damper divides the inside of the rotary cylinder into two chambers with a rotary piston, and the function of the stay damper is replaced by a rotary damper that generates a strong resistance force in one direction on the circumference and a weak resistance force in the opposite direction. be able to.

Next, the operation of the movable handrail will be described. The retracting operation of the movable handrail is performed by lifting the support rod 2 in the use position shown by the solid line in FIG. 1 toward the wall surface A. When the support rod 2 is lifted, the rotary base body 3 rotates about the rotary shaft 4, and as shown in FIG. 3, the rotary base body leaves the locking stopper 13 and rotates 90 degrees toward the drawing. By the way, it abuts on the storage stopper 14. When this end point, that is, when the support rod 2 is inverted and put into the retracted state, the rotating base body 3 in that posture has a protrusion 17 attached to the tip thereof and a locking tool 16 provided on the back surface of the storage stopper 14. Are engaged and their posture is maintained. In the operation of feeding the support rod 2 into the use state from the storage position shown in FIG. 3, first, a force is applied to the support rod 2 in the direction of the arrow B to release the engagement of the locking tool 16 and the rotating base 3 is moved. First move to rotate. Immediately after this, the rotating base body 3 starts to rotate due to the weight of the supporting rod 2 acting on it, but the braking mechanism works against the force that is about to rotate, and braking is performed so as to reach the set desired speed. In addition, the support rod 2 is loosened, de-energized, and gently fed at a safe speed.

[0018]

The present invention has the following effects.

A. Since the rotating base body rotatably mounted in the gap of the bracket is limited in its rotating speed by the braking mechanism, the supporting rod mainly composed of the handrail is formed integrally with the rotating base body. The handrail with high safety can be obtained because the power can be gently deviated from the storage position to the horizontal state and fed out.
B. Locking tools such as roller catches and magnet catches are provided between the bracket and the rotating base, and the rotating base mainly composed of handrails that is inverted to the storage position is semi-fixed so that it can be detachably held with respect to the bracket. As a result, the support rod mainly composed of the handrail is prevented from being unexpectedly lowered and extended.

C. Since the dangerous parts of the rotary base and the mechanically operating part connected to the support rod are surrounded by a pair of plates, hold your hand or fingers between the support rod and the bracket when storing or extending the support rod. The risk of injury is gone.
