Description

[Detailed description of the invention] (Industrial application field) The present invention relates to handrail devices installed on stairs, etc.
More specifically, the present invention relates to a handrail device that allows a handrail to be stored as needed.

(Prior Art) Handrails have conventionally been installed on passageways or stairs used by elderly people, physically disabled people, and the like. These handrails require functionality rather than appearance, but it is generally recommended that a pipe with a diameter of 40 to 50 mm be placed at a height of 1000 to 1100 mm above the floor. By the way, the handrail always protrudes toward the passageway.

(Problem to be solved by the invention) As mentioned above, conventional handrails always protrude toward the aisle, so when installing a handrail, the aisle or staircase must be made considerably wide, and the aisle or staircase must be considerably widened relative to the building area. There is a problem in that the proportion of

In addition, if handrails are installed in passages or stairs in a building that did not take into consideration the installation of such handrails at the beginning, there is a problem that people who do not need handrails will feel oppressed because the width of the passage is narrow. There is.

This idea was created in view of the above problems.
The purpose is to provide a handrail device that can be installed even in narrow aisles or stairs, and, if necessary, can provide approximately the same width of passage as without a handrail.

(Means for Solving the Problems) The present invention that solves the above problems includes a handrail for pedestrians to hold on to, a handrail support portion that moves and supports the handrail to a use position and a storage position, and The handrail is characterized by a locking mechanism that locks the handrail in the storage position and the storage position, an interlocking mechanism for the locking mechanism, and a locking mechanism disposed at both ends of the handrail to unlock the locking mechanism.

(Function) In the handrail device of the present invention, the handrail can be moved to the storage position or the use position by operating the lock release lever. Further, since the lock release levers are located at both ends of the handrail, the position of the handrail can be changed as necessary immediately before or after entering or exiting a passage or staircase with a handrail device.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 8. In these figures, 1 is a handrail for a pedestrian to hold on to, and 2 is a handrail support portion that moves and supports the handrail 1 to the use position and storage position. This handrail support part 2 includes a handrail support part 2 (E) at the end of the handrail device, and an intermediate handrail support part 2 in the middle.
It is divided into (M). Each handrail support part 2 has a mounting seat 3,
an arm 4 having a semi-cylindrical support portion at its tip;
It is composed of a casing 5 attached to a semi-cylindrical portion of the arm 4. By attaching the casing 5 to the tip of the arm 4, that is, the semi-cylindrical support portion, a cylindrical holding portion is formed there. On the inner peripheral surface of the holding part, one protrusion 16 is provided on the end handrail support part 2 (E), and one protrusion 16 is provided on the intermediate handrail support part 2 (E).
In (M), two cable holders are provided, and a substantially cylindrical cable holder 6 is rotatably held.

Moreover, the end of the cylindrical holding part is attached to the end handrail support part 2.
In (E), the middle handrail support part 2 is also held on one side.
In (M), the handrail 1 is sandwiched on both sides (preferably screwed for strength). On the other hand, the base end of the arm 4 is rotatably supported by a shaft 7 on a mounting seat 3, and the mounting seat 3 is screwed onto a wall surface with four screws 8.

The cable holder 6 has three through holes 6a, 6b, and 6c having axial slits. The cable holders 6 in each adjacent handrail support part 2 are connected by a connecting cable 9. The connecting cable 9 consists of an inner cable 9a and an outer cable 9b. The outer cable 9b is made of a non-stretchable material and has a tube shape, and the inner cable 9a passes through it. Cylindrical fasteners 10a are attached to both ends of the inner cable 9a, and are fitted and locked into adjacent cable holders 6a and 6b, and both ends of the outer cable 9b are fixed to the adjacent casing 5. Furthermore, spiral grooves 6d and 6e are provided on the outer peripheral surface of the cable holder 6 for guiding the connecting cable 9 to the end surface of the cable holder 6 from an intermediate position between the through holes 6a and 6b. On the other hand, the other end of the lock cable 12, which has one end connected to the lock stopper 11 that prohibits the rotational movement of the arm 4 with respect to the mounting seat 3, has a through hole 6c.
A stopper 10b is provided which is fitted into and locked to. Further, a groove 6f is provided on the outer peripheral surface of the cable holder 6 for guiding the lock cable 12 in the circumferential direction of the cable holder 6 from an intermediate position of the through hole 6c. A substantially J-shaped through hole 4a is bored inside the arm 4, and a lock cable 12 and a compression coil spring 13 are coaxially inserted into the through hole 4a. The compression coil spring 13 is inserted into the lock cable 12 through the through hole 4a.
A spring stopper 17 is attached to the locking cable 12 to prevent it from extending into the J-bend. The compression coil spring 13 applies an outward biasing force to the spring stopper 17, and applies tension to the lock cable 12 between the cylindrical stopper 10b and the spring stopper 17. Two recesses 14a, 14b are provided on the sliding surface of the mounting seat 3 with the arm 4, in a portion facing the opening of the through hole 4a, and these recesses 14a, 14b are used to prevent the arm 4 from rotating. The recess 14a is located on the trajectory drawn by the opening of the through hole 4a when the arm 4 is in the storage position of the handrail, and the lock stopper 11 is fitted into the recess 14a.
The recess 4b is arranged so that the lock stopper 11 is fitted into the recess 4b when the handrail is in the use position. Further, the bottom surface of the base of the arm 4 comes into contact with the mounting seat 3 when the arm 4 is in the use position, thereby restricting the downward rotational movement of the arm 4. End handrail support parts 2 (E) are always installed at both ends of the handrail device, and if necessary, an intermediate handrail support part 2 (M) is installed at the middle part of the handrail device.

A lock release lever 15 is fitted onto one end surface of a cylindrical holding part formed by the casing 5 and the tip of the arm 4 in the end handrail support part 2(E). Three protrusions protrude from the back surface of the lock release lever 15, and these protrusions fit into through holes 6a, 6b, and 6c drilled in the end face of the cable holder 6, respectively, so that the lock release lever 15 and the cable holder 6 rotates as one. However, as shown in FIG. 8, since the grooves 6d and 6e are spiral, the rotation direction of the lock release lever 15 of the end handrail support part 2 (E) is one direction (counterclockwise when viewed from the lock release lever 15). )
Moreover, the locking wire 12 is limited to the groove 6.
Since it is wound within f, the rotation angle is also limited.

However, as shown in FIG. 7, due to the sliding contact between the protrusion 15a provided on the upper part of the lock release lever 15 and the arcuate groove 5a provided in the casing 5, the lock release lever 15 and the cable holder 6 fitted therewith are in sliding contact with each other. The rotation range and direction of rotation are regulated.

According to the above configuration, when moving the handrail from the storage position (indicated by a solid line) to the use position (indicated by a broken line) in FIG. 1 or 4, first the end handrail support part 2 (E) When the lock release lever 15 located in is rotated counterclockwise, the
As shown in the figure, the cable holder 6 also rotates counterclockwise, and the lock cable 12 is guided by the groove 6f and wound in the circumferential direction of the cable holder 6. Then, the lock stopper 11 connected to the lock cable 12 is pulled into the through hole 4a, the fitted state between the lock stopper 11 and the recess 14a is released, and the arm 4 becomes rotatable.

On the other hand, adjacent cable holders 6 are connected by connecting cables 9, and more specifically, by inner cables 9a as described above. Further, since the outer cable 9b is fixed to each casing 5 and does not expand or contract, it serves to guide the inner cable 9a.

Here, when the cable holder 6 of the end handrail support part 2 (E) rotates counterclockwise, the inner cable 9a is pulled in the rotation direction of the cable holder 6, and the adjacent connected cable holder 6 is also pulled in the same direction. As it rotates, the adjacent lock stopper 11 is also drawn into the through hole 4a. Therefore, the lock mechanisms in all the handrail supports 2 can be interlocked by operating the lock release lever 15 of the end handrail support 2 (E). When the arm 4 rotates until the opening of the through hole 4a reaches above the recess 14b, the base surface of the arm 4 abuts the mounting seat 3, and further rotation is prohibited. When the lock release lever 15 is released, the spring stopper 17, which is biased to project outward by the compression coil spring 13, returns to its original position.
By pulling the lock cable 12, the cable holder 6 is also returned to its original position. At this time, the lock stopper 11 is projected and fitted into the recess 14b by the elastic force of the lock cable 12, and the locking at the use position is completed.

Conversely, moving the handrail from the use position (indicated by a broken line) to the storage position (indicated by a solid line) can also be achieved by the same operation as described above.

According to this configuration, the handrail 1 can be locked by the lock release lever 1.
By the operation 5, it can be moved to the storage position or the use position as necessary. Further, since the lock release levers 15 are located at both ends of the handrail, the position of the handrail 1 can be changed as necessary just before entering or exiting the passageway where the handrail device is located. Furthermore, even if a third party accidentally releases the lock while using the handrail, the arm 4
The bottom surface of the base presses against the mounting seat 3 when in the use position and prevents downward rotation, which prevents accidents such as the user's fingers getting stuck between the handrail and the wall. .

Note that the present invention is not limited to the above embodiments.
For example, it is sufficient to have a locking mechanism at least on the end handrail support 2(E). Further, as an interlocking function, a shaft having sufficient torsional stiffness may be passed through the center of each wire holder 6 instead of the connecting cable 9 and used as a transmission shaft.

(Effects of the invention) As explained above, according to the invention, the handrail can be moved to the use position and the storage position,
When the handrail is in the use position and storage position, the lock works and prevents the handrail from rotating, and all locks can be released by operating the lock release levers at both ends of the handrail.
