Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a public telephone stand, and particularly to a public telephone stand devised so that it can be conveniently used by children and handicapped persons.

BACKGROUND OF THE INVENTION Telephones have become indispensable in social life, and especially in urban areas, public telephones are installed at various locations and are conveniently used.

Public telephones are often installed in public phone booths when outdoors, and on simple stake-shaped stands when indoors, especially in the latter case. It is a common practice to make the stand into a long pile so that a large number of telephones can be installed side by side and used by many people.

Public telephone stands used for such purposes (referring to the stand on which the telephone is placed when a public telephone is installed; the same shall apply hereinafter) shall not be attached directly to the wall of the telephone booth. It is usually a fixed shelf-like structure, and indoors, as mentioned above, it is usually a stake-like structure or a long stake-like structure. It is common to have an attached shelf and storage space for telephone directories, etc.

The problem to be solved by the invention is that when using the prior art, the height of the shelf-like or stake-like part on which the telephone is placed is fixed and cannot be adjusted at all. Because there was -
Although it is convenient for adults who are taller than a room to use the telephone, it is extremely inconvenient for children, disabled people who use wheelchairs, etc. to use the telephone because the telephone is too tall. was there.

Therefore, in view of the problems of the prior art, this invention is designed to make the telephone stand on which the telephone is placed move up and down, and by making it possible to freely adjust its height, it can be used not only for adults but also for adults. To provide a public telephone booth devised so that even children, handicapped persons, etc. can conveniently use the telephone.

Means for Solving the Problems The structure of this invention to achieve the above object includes a vertical frame, a telephone stand that is movable up and down on the front side of the vertical frame, and a fixed pulley attached to the upper end of the vertical frame. One end of the cable wrapped around a fixed pulley is connected to a telephone stand, and a weight is suspended from the other end, while the telephone stand is equipped with a stopper mechanism to fix it at a predetermined height. This is the summary.

Further, the weight can be made slightly heavier than the total weight of the telephone stand.

With this configuration, the weight of the telephone stand is offset by the weight, so by releasing the stopper mechanism, the telephone stand can easily move up and down on the front of the vertical frame. Therefore, its height can be arbitrarily adjusted according to the height of the user. Furthermore, when the height adjustment operation is completed, if the stopper mechanism is activated at that position, there is no possibility that the telephone stand will move up and down inadvertently.

If the weight of the weight is slightly heavier than the total weight of the telephone stand, the telephone stand will always receive upward force, which will not only make it easier to lift the phone stand, but will also prevent the phone stand from becoming damaged. Accidents caused by accidental falls can be prevented. In addition,
At this time as well, the operator's body weight can be used to push down the telephone stand, making it extremely easy.

It works as described above.

Example Examples will be described below with reference to the drawings.

The public telephone stand consists of a vertical frame 10 and a telephone stand 20 (FIGS. 1 and 2).

The vertical frame 10 is constructed by attaching a front plate 12 to the front side of a frame body 11 formed by assembling structural materials such as channel steel into a frame shape, and a pair of fixed pulleys 13. 13 is installed.

A cable 14 is wound around each of the fixed pulleys 13, 13, one end of which is connected to the telephone stand 20, and a common weight 15 suspended from the other end. The weight 15 is a rectangular flat block body, and rollers 15a115a... are provided protruding from both end surfaces of the weight 15.
% 15a... are arranged to move along a pair of guides 16.16 vertically attached to the inner surface of the frame body 11.

The telephone stand 20 includes an upper plate 21 on which a telephone T is placed, a lower plate 22 forming a space for storing a telephone directory B, etc.
It is made up of a combination of a back plate 23 and side plates 24, 24, and a mounting plate 25 is fixed to the back side of the back plate 23, while a stopper mechanism 30 is assembled to the lower surface of the lower plate 22.

However, the mounting plate 25 is bent into a U-shape, and the bent portions 25a, 25a on both sides are formed by a pair of slits F 12 a s 1 formed in the front plate 12 of the vertical frame 11.
2a protrudes toward the vertical frame 10 side (
Figure 3).

An L-shaped bracket 25b is fixed to the inner surface of each bent portion 25a of the mounting plate 25, and one end of the above-mentioned cable 14 is connected via a wire connector 14a screwed onto the bracket 25b. Further, guide rollers 25d, 25d, etc. are attached to the outer surface of the bent portion 25a via a mounting plate 25C.
・Attached to the shaft, guide rollers 25d, 25d...
is adapted to move within a channel-shaped guide rail 17 vertically attached to the inner surface of the frame body 11. Stopper brackets 17a, 17a for regulating the vertical movement stroke of the telephone stand 20 are attached to both the upper and lower ends of the guide rail 17.

The stopper mechanism 30 as a whole is assembled on the lower surface of the lower plate 22 (FIGS. 1 and 2), and includes an operating lever 31 with a grip 31a projecting forward and an operating lever 31.
The main members are a rotating piece 32 that fixes the rotating piece 32, and a stopper shaft 33, 33 that engages with the rotating piece 32 and moves from side to side.

The rotating piece 32 is a short hollow prismatic member, and is a member of the lower plate 2.
Bracket 32a fixed to the bottom surface of 2 and bracket) 3
The operating lever 31 is pivoted horizontally via a central shaft 32b provided upright (FIGS. 4 and 5), while the operating lever 31 is mounted on a mounting piece integral with the rotating piece 32. It is fixed in parallel to the rotating piece 32 via 32c.

The rotary piece 32 is formed with elongated holes 32d, 32d, . 3
A bottle 33a that engages with the holes 2d and 32d is implanted.

Moreover, the stopper shafts 33 and 33 are respectively sliding brackets) 33b.

33b, etc., and are fitted with stopper rings 33c, 33c for determining a predetermined movement stroke. Therefore, when the operating lever 31 is placed in the upright position (solid line in FIG. 4), the tips of the stopper shafts 33 and 33 protrude from both the left and right sides of the lower plate 22 by a predetermined distance, and the operating lever 31 is moved to the left. If it is tilted (double-dashed line in the figure), the stopper shaft 33.
33 is designed to be able to be stored on the lower surface of the lower plate 22.

A guard plate 34 is provided vertically on the front side of the stopper mechanism 30 (FIGS. 1 and 2), and the operating lever 31 is
It passes through a long hole 34a formed in the guard plate 34. In addition, a long hole 3 corresponding to the upright position of the operating lever 31 is provided.
Lock balls 34b, 34b are attached to one end of 4a (FIGS. 5 and 6), so that the operation lever 31 in the upright position can be lightly locked.

A public telephone stand with such a configuration is a prefabricated partition device W.
(Figure 7).

The partition device W includes studs W1, Wl and a partition plate W2,
By alternately connecting the studs W1 and W2, the interior space can be partitioned freely.
, Wl are approximately the same as the vertical frame 10,
By protruding the side walls W3, W3, it is possible to form a telephone space WT for accommodating a public telephone stand on the front surface of the partition plate W2. In addition, inside each of the side walls W3, W3, there is a recess W3aSW3 corresponding to the stopper shaft 33.33.
a... (Fig. 2, Fig. 4), and the stopper plates W3b, W3b are attached ((Fig. 7). However, the recesses W3as W3a... The stopper plate and wab are provided with through holes W3cSW3c at positions corresponding to the recesses W3aSW3a.

Now, when the operating lever 31 of the stopper mechanism 30 is placed in the upright position, each tip of the stopper shaft 33.33 protrudes left and right from the lower surface of the lower plate 22 of the telephone base 20, so the height of the stopper shaft 33.33 is position on the side walls W3, W
3, the stopper shaft 33.33 engages with the recess w3aSW3a and fixes the height of the telephone base 20 to the high position. (Figure 2).

Next, when the operating lever 31 is tilted to the left, the stopper shafts 33, 33 are entirely housed in the lower surface of the lower plate 22, so that the telephone base 20 can be moved downward. Then, push down the telephone base 20 and stopper shaft 33.
．． By aligning the height position of 33 with the lower recess W3as W3a and returning the operating lever 31 to the upright position, the telephone stand 20 can be fixed at a low position convenient for use by the disabled person M, for example. (double-dashed line in Figure 1).

Note that the vertical movement stroke of the telephone stand 20 is determined by the stopper brackets 17a, 17 attached to the frame body 11.
Since the stopper shaft 33.a can be regulated by the stopper shaft 33.
33 and concave IW3aSW3a...If the toner position is properly aligned, the vertical movement of the telephone base 20 will be easier. Furthermore, when the telephone base 20 moves up and down, the weight 15 cancels out the total weight of the telephone base 20 including the telephone T, etc., so if the weight 15 is made to be slightly heavier, the telephone base 20 The vertical movement operation is extremely light,
Moreover, it can be done safely. However, it goes without saying that the weight of the weight 15 may be approximately the same as the total weight of the telephone stand 20.

Note that this public telephone stand can not only be combined with the partition device W, but also be incorporated into a public telephone box for outdoor installation inside a shell. In addition, telephone stand 20
The height position may be individually adjusted as desired by providing a large number of recesses W3asW3a in the vertical direction.

As described in detail, according to this invention, a vertical frame and a telephone stand are combined, a fixed pulley is provided on the vertical frame, and the telephone stand is connected to A fixed pulley allows the telephone stand to move up and down freely on the front of the vertical frame, and is equipped with a stopper mechanism to fix it at a predetermined height, allowing the height of the telephone stand to be freely adjusted and set simply by operating the stopper mechanism. This has an excellent effect in that even children with disabilities or people with disabilities can use the telephone conveniently.
