[0009]
【Example】
An embodiment of a movable handrail according to the present invention will be described with reference to FIGS.
[0010]
FIG. 1 shows a movable handrail according to an embodiment of the present invention. The movable handrail can rotate the handrail main body 1 from the horizontal use position shown by a 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 mounted in the vertical direction.
[0011]
As shown in FIGS. 1 and 3, the handrail main body 1 fixes the base end portion of the support rod 2 having a substantially U-shaped cross section to the rotating base 3, while the rotating base 3 is attached to the bracket 5 by the rotating shaft 4. The support rod 2 is pivoted about the rotation shaft 4 so as to be pivotably mounted in the gap. The movement of the rotating base 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 turning base in the horizontal state abuts against the storage stopper 14, and the turning base in the vertical state abuts on the locking stopper 13 so that the contact points cannot be exceeded. Further, a rubber cushion (not shown) is interposed at the contact point so that the impact at the time of contact is reduced.
[0012]
When the support rod 2 is turned upside down to be in the retracted state, the rotating base body 3 in the posture is locked like a roller catch or a magnet catch in which the protrusion 17 attached to the tip of the support base 2 is provided on the back surface of the retractable stopper 14. The tool 16 is engaged and its inverted state is maintained. When the support rod 2 of the handrail main body 1 is extended in a horizontal state, a lateral force is applied to the support rod 2 to disengage the locking tool 16.
[0013]
The bracket 5 has a pair of plates 15 formed by bending a mounting portion with respect to a wall surface facing each other at an interval such that the rotating base 3 can rotate, and integrally with the storage stopper 14 and the locking stopper 13. It is composed. The middle of the bracket 5, have been drilled holes for supporting the rotary shaft 4, pivotally attached to rotate the substrate 3 in the pores, and so as to rotate in the gap of the bracket 5.
[0014]
Next, a description will be given of the braking mechanism 12 that limits the rotation speed of the rotating base 3 that 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, this braking mechanism is connected to a first link 6 pivotally attached to a fulcrum 9 on the plate 15 side and a second link 7 pivotally attached to a fulcrum 10 on the rotating base 3 side. The stay damper 20 provided between the point 8 and the wall surface fulcrum 11 is provided to limit the displacement speed of the connection contact 8, and the displacement of the connection contact 8 that is displaced in accordance with the movement of the rotating base 3. The brake is applied to the desired set speed against the force to freely rotate the speed by the stay damper.
[0015]
Even if the brake mechanism 12 is configured to provide a stay damper between the fulcrum 10 fixed to the rotating base and the wall surface fulcrum 11 to limit the displacement speed of the fulcrum 10, the braking mechanism 12 is displaced with the movement of the rotating base 3. It is possible to apply braking so that the displacement speed of the fulcrum 10 is resisted by the stay damper against a force to freely rotate and at a desired set speed. For example, as shown in FIG. 4, the stay damper 20 divides the inside of a cylinder 21 into two chambers C and D by a piston 22, and adjusts the buffer solution or gas in one chamber to the other chamber while adjusting the orifice 27. A gas spring that is moved to exert a strong repulsive force in the extending direction of the piston rod 23 is suitable. Reference numeral 24 is an oil seal, 25 is a free piston, and 26 is a gas chamber in which nitrogen gas is press-fitted and the chambers C and D are constantly pressurized. In addition, it is needless to say that a gas spring can be substituted for a mechanical spring or a combination of a spring and a buffer or gas as long as it has the above function.
[0016]
Furthermore, another embodiment of the braking mechanism will be described.
As shown in FIG. 5, in this braking mechanism, a rotary shaft is directly connected to the rotary base 3, a rotary damper 31 is provided between the rotary shaft extending outward from the plate 15 and the plate, and the rotary damper is free to rotate. The rotating base 3 is applied with braking. In the rotary damper, for example, a friction disk 31 is directly connected to the rotating base 3, and a brake 32 that works strongly in one direction by a wedge action and weakly works in the opposite direction is brought into contact with the rotary base 3 to directly and freely rotate the rotating base 3 itself. Brake is applied against the force to be moved and at a desired set speed. In addition to this, the rotary damper divides the inside of the rotary cylinder into two chambers with a rotary piston and replaces the function of the stay damper with a rotary damper that generates a strong resistance force in one direction and weak resistance in the opposite direction. be able to.
[0017]
Next, the operation of this movable handrail will be described.
The operation of storing the movable handrail is performed by lifting the support rod 2 at the use position indicated by the solid line in FIG. When the support rod 2 is lifted, the rotation base 3 rotates about the rotation shaft 4 and the rotation base leaves the locking stopper 13 and rotates 90 degrees toward the figure as shown in FIG. By the way, it contacts the storage stopper 14. When the end point, that is, when the support rod 2 is inverted and is in the retracted state, the rotating base 3 in that posture is provided with 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 the posture is maintained. The operation of extending the support rod 2 from the retracted position shown in FIG. 3 to the use state first applies a force to the support rod 2 in the direction of the arrow B, disengages the locking tool 16, First move to rotate. Immediately after this, the rotation base 3 starts to rotate due to the weight of the support rod 2 acting on it, but the braking mechanism works against the force to rotate, and the braking is performed so that the desired speed is set. is added, the supporting rod 2 is gently Repetitive out a gentle Ku energy dissipation is safe speed.
