Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a large clock that is mounted at a high place on a wall such as a gymnasium or hall.

Figure 1 shows the structure of a conventional large wall-mounted clock and its mounting device. As shown in the figure, the clock body 1 is composed of a front frame 2 and a rear frame 3, both of which are They are pivoted to each other by hinges 4. A front glass plate 5 and a dial plate 6 are attached to the front frame 2, and a clock drive unit 7 is mounted behind the dial plate 6.
is installed. 8 is the minute hand, 9 is the hour hand,
These are designed to be driven by a clock drive section 7. Reference numeral 10 denotes an anchor bolt driven into the wall surface 11, and the back plate 13 of the watch body 1 can be fixed to the wall surface 11 by tightening a hexagonal nut 12. To explain the procedure for attaching the watch body 1 to the wall surface 11, first, use a template or the like to drive the anchor bolts 10 into predetermined positions on the wall surface 11, and then lift the watch body 1 with a crane or the like. An anchor bolt 10 is fitted into a mounting hole provided in a back plate 13 of No. 1. Furthermore, the front frame 2 of the watch body 1
is opened and the hexagonal nut 12 is tightened to the anchor bolt 10. Installation work is carried out according to the steps above, but anchor bolts 10
When fitting the mounting hole of the back plate 13 of the watch body 1 and when tightening the hexagonal nut 12, it is necessary to open the front frame 2. It is very inconvenient to work while supporting the watch, and a large watch with a diameter of about 700 mm weighs about 20 to 30 kg, so it is very dangerous to work at high places using a crane truck. There was a problem.

The present invention was devised to solve these problems of the conventional example, and the purpose is to provide a mounting device for a large watch that allows a large watch to be mounted easily and safely even at high places. That is.

The configuration of the present invention will be described below with reference to illustrated embodiments. FIG. 2 shows an embodiment of the present invention, and as shown in the figure, a hook 14 is fixed to the upper end of the back plate 13 of the watch body 1, and a mounting bracket is attached to the wall surface 11. 15 is fixed, and the upper end 16 of the mounting fitting 15 is adapted to be engaged with the hooking fitting 14. 3 and 4 show the specific structures of the hook 14 and the mounting bracket 15. First, the hook 14 consists of a fixing piece 17 attached to the back plate 13 of the watch body 1, and a mounting bracket 15. and an engaging portion 18 that engages with the upper end portion 16, and this engaging portion 18 is connected to a substantially triangular side plate 19.
a and an inclined plate 19b, and has a downwardly expanding shape, so that it can be easily engaged with the upper end portion 16 of the mounting bracket 15. Fixing pieces 17 on both sides of the hook 14 are fixed to the back plate 13 of the watch body 1 by means of screws, welding, or the like. As shown in FIG. 4, the mounting bracket 15 is provided with stepped portions 20 and 21 at both the upper and lower ends, and the portion of the mounting bracket 15 that is attached to the wall surface 11 has a lead wire connected to the clock drive unit 7. 22 and a mounting hole 2 for passing the anchor bolt 10 protruding from the wall surface 11.
4 and 25 are provided. Mounting holes 24, 25
As shown in FIG. 2, a hexagonal nut 12 is tightened and fixed to the anchor bolt 10 passed through the anchor bolt 10. Furthermore, a screw insertion hole 27 is formed in the lower end 26 of the mounting bracket 15, and an L-shaped bracket 28 provided at the lower end of the watch body 1 is screwed into the lower end of the mounting bracket 15, as shown in FIG. It is designed to be able to be stopped. The watch body 1
The structure is almost the same as that of the conventional example shown in FIG. 1, but when using the mounting device of the present invention, it is not necessary to be able to open and close the front frame 2 of the watch body 1. A front frame 2 and a rear frame 3 are integrated to form a watch body 1, thereby reducing the overall weight. Furthermore, FIG. 5 shows the operation when connecting the lead wire 22 to the watch body 1 using the mounting device of the present invention. Since the lead wire 22 can be rotated in the direction shown by the arrow A, the lead wire 22 can be introduced into the watch body 1 while the watch body 1 is supported by the mounting bracket 15. It is.

The present invention is constructed as described above, and includes a downwardly opening hook fitting that is attached to the upper end of the back of a large watch, and an upwardly protruding portion that engages the hook fitting.
It consists of a mounting bracket that is attached to a structure such as a wall, so when attaching a large, heavy clock to a wall, etc., it is necessary to attach the hooking bracket to the mounting bracket that has been attached to the wall or other structure in advance. The installation operation can be performed simply by aligning the anchor bolts with the front frame of the watch body open, which simplifies the installation process itself. Since there is no need to tighten hexagonal nuts or hex nuts, there is no need to work in unstable conditions at high places, and there is less danger when installing heavy items such as large watches at high places. There is an advantage. Furthermore, when using the mounting device of the present invention, there is no need to open and close the front frame of the watch body, so the watch frame can be integrated.
It also has the advantage of being able to reduce the overall weight of a large watch that is worn at a high place, by providing a stepped portion at one longitudinal end of a long strip-shaped metal plate and moving the stepped portion upward. A hooking fitting is formed with a mounting fitting as a protruding part, and has a downwardly expanding inclined plate having approximately the same width as the width of the mounting fitting, and a pair of substantially triangular side plates supporting both ends of the inclined plate. Because of this, the watch body can be rotated around the upper end of the mounting bracket and the lower end of the watch body can be separated from the wall surface, making it easy to introduce the lead wire pulled out from the wall surface into the watch body. is possible,
A further advantage is that the watch body can be mounted in an inclined position.
