Description

[Detailed description of the invention] ``Purpose of the invention'' This invention relates to the invention of a box mounting mechanism that allows communication transmitting/receiving equipment or television receiving equipment such as amplifiers and mixers to be mounted on masts or The purpose is to simplify the mechanism for attaching to a wall or the like using the same member, to ensure stability even when attached to a wall, and to obtain a low-cost mechanism.

(Industrial field of application) A mechanism for attaching television reception equipment or communication transmission/reception equipment, such as an antenna common listening case, to a mast or wall.

(Prior art) Equipment for transmitting and receiving communications, amplifiers, mixers, and other television reception equipment must be installed on pillars such as antenna masts, walls (including pillars), etc. at each installation site. Conventionally, it has been common to use different members as required for each case. That is, when attaching to a mast, attach a U-bolt or a similar bent bolt to the box that engages the mast, and use a member such as a strip nut, and when attaching to a wall, attach the box to the wall. A mounting seat member is provided to set it in a stable state, and it is fixed to the wall using screws. This requires preparation and setting, and the necessary parts for installation are duplicated and need to be replaced, which is complicated and disadvantageous in terms of both cost and installation man-hours. For this reason, it has been proposed to use multiple metal fittings for some parts and change the mounting relationship of the metal fittings in each case, but it is disadvantageous to have multiple metal fittings for installation, and The number of auxiliary members such as screws, nuts, and bolts for attaching the plurality of metal fittings must also increase.

In order to avoid the above-mentioned disadvantages of the conventional ones, the present inventors have proposed Utility Model Application No. 57-77618 (Utility Model Application No.
58-180687). In other words, the invention of this inventor's earlier application provides a mounting seat with a joint surface that corresponds to the circumferential surface of the mast on the box body, and a mounting bracket that has a curved surface that corresponds to the joint surface in the middle part. is provided with engaging protrusions that engage with the side surfaces of the mounting seat on both sides of the curved surface, and a fitting hole is provided in the mounting seat in the width direction for attaching the U bolt to the tilting itself. Furthermore, a screw receiving portion is formed on the side of the mounting seat to hold a screw to be attached to the mounting fitting.

(Problems to be solved by the invention) The above-mentioned earlier application by the present inventors can be mounted to either a mast or a wall using the same mounting mechanism, and is extremely effective. However, the structure is such that engaging protrusions for engaging the mounting bracket with the side surface of the mounting seat are provided, and such engaging protrusions are engaged with engaging grooves provided on the side surface of the mounting seat. However, both the mounting seat and the mounting bracket are complicated and require a considerable amount of man-hours to manufacture.

Also, in its handling, the vertical bent surfaces on both sides of the curved surface formed in the middle part of the mounting bracket are joined to the side surfaces of the mounting seat, and the engaging protrusion is tightly fitted into the engaging groove while being fitted and inserted. It is necessary to engage
Such engagement and disengagement operations are not easy.

Furthermore, the engagement between the relatively small engagement protrusion of the mounting bracket and the engagement groove of the mounting seat is pointwise, and when both ends of the mounting bracket are tightened against the wall surface with screws, the engagement between the engagement grooves of the mounting bracket and the engagement groove of the mounting bracket is pointwise. Since both ends of the mounting bracket floating from the wall surface are pulled toward the wall surface by the vertically curved surfaces formed, they are subjected to an acting force in the direction of disengaging the engagement protrusion from the engagement groove. The situation is not always stable. In order to avoid such disadvantages, it is necessary to make the mounting bracket thick and strong, and its manufacture requires strong processing, which increases costs both in terms of materials and processing.

``Structure of the invention'' (Means for solving the problem) A mounting seat with a joint surface that corresponds to the circumferential surface of the mast is provided protruding from the box body, and a curved surface that corresponds to the circumferential surface of the mast is also provided in the middle part. A U-bolt is mounted on the mounting seat so that it can be raised and lowered, and a curved fitting groove is provided between the mounting seat and the box body to receive the curved surface portion of the mounting bracket. A box mounting mechanism characterized by having an opening formed on the end face of the seat.

(Function) By fitting the curved surface portion of the intermediate portion of the mounting bracket into the curved fitting groove, the mounting bracket is fitted into the mounting seat of the box, and furthermore, the movement of the mounting bracket in the length direction is prevented. form a blocked attachment relationship.

Both ends of the mounting bracket are set on the wall as they are, and fixed with screws or the like.

By removing the above-mentioned mounting bracket from the mounting seat, inverting it, and attaching it to the upright U-bolt, the joint surface of the mounting seat and the curved surface of the mounting bracket will face each other, and the joint surface and the curved surface will be in contact with each other. Therefore, it can be set to be clamped to the mast.

Cargo is handled and packed with both the U-bolts and mounting hardware fixed to the box.

(Example) To explain the specific embodiment of the present invention shown in the attached drawings, as shown in FIG. 5, the bottom surface of the box 1 made of synthetic resin is The mounting seat 11 having a joint surface 12 that corresponds to the circumferential surface of the mast 6 is integrally formed, as in the earlier application described above, and a curved surface 22 that corresponds to such a joint surface 12 is formed in the intermediate part. The use of the mounting bracket 2 formed in the same manner as in the previous application is also the same as in the previous application. Furthermore, as shown in FIGS. 4 and 5, the mounting seat 11 is provided with a fitting hole 13 in the width direction for mounting the U-bolt 3 as shown in FIG. It is also the same as that of the above-mentioned earlier application that the U bolt 3 is provided so as to be able to rise and fall on the back surface of the box body 1, but in the present invention, the back surface corresponding to the thickness of the joint surface 12 of the mounting seat 11 is and box body 1
The curved surface 2 of the mounting bracket 2 is between the protruding portion 10 of
A curved fitting groove 18 is formed to receive the two parts from the end surface direction of the mounting seat 11.

In this embodiment, a screw receiving portion 15 is formed on the side of the mounting seat 11 described above to receive and hold the screws 4, 4 to be installed in the mounting holes 25, 25a of the mounting bracket 2. Moreover, a projecting edge part 16 having one end as an inclined edge 16a is provided on the side of the mounting seat 11, and is connected to the back surface of the box body 1 as shown by the solid line in FIG. When the attached U-bolt 3 is pulled up as shown by the imaginary line, a protruding edge 1 is formed on the inner surface of the U-bolt 3.
6 and 16 to properly maintain their upright state. Furthermore, the above-mentioned fitting hole 13
is formed in the shape of a long hole, and the U-bolt 3 is made to have an inclined shape with respect to one surface of the box body, and the inclination angle is further increased while sliding the U-bolt 3 to the side. Although the U-bolt 3 can be removed by doing so, it is preferable to leave it in the state shown by the solid line in FIG. 4 when handling it as a product or packing it.

The above-mentioned mounting bracket 2 is assembled by fitting its curved surface 22 into the curved fitting groove 18 of the mounting seat 11 as shown by the chain line in FIG.
The mounting bracket 2 is assembled in such a way that it does not slide in the length direction, and both ends of the mounting bracket 2 installed in this way are set between the back of the box and the solid line in Fig. 4 mentioned above. Prevents the U-bolt 3 from standing up. However, the state in which the mounting bracket is attached to the wall surface 8 is as shown in FIG. 3, with the flat parts 24 on both ends being set stably, and therefore the state in which the box body 1 is attached to the wall surface 8 is as shown in FIG. It is clear that it will be stable.

In addition, when attaching to the mast 6, the mounting bracket 2 is removed as shown in Figure 5, and then the U-bolt 3 is raised up on the back surface of the box body 1, and the mast 6 is interposed between the joint surface 12 of the mounting seat 11 and the joint surface 22 of the mounting bracket 2 which is attached to the raised U-bolt 3 by reversing the mounting state to the mounting seat 11 as described above, and the nut 7 screwed onto the U-bolt 3 can be tightened, thereby accomplishing easy and accurate attachment to the mast 6 in the same way. When mounting the U-bolt 3 on the mast 6, one 25a of the mounting holes 25, 25a is formed in an arc shape centered on the other 25 and opens to the side, as shown in Figure 6. Moreover, a protrusion 26 is provided on the opening side of the mounting hole 25a, as shown in Figures 7 and 8. The U-bolt 3 engages with this protrusion 26 and is set in the back, thereby forming an appropriate setting state. Moreover, by simply loosening the nut 7 slightly, one side of the U-bolt 3 can be released from the mounting hole 25a, allowing the U-bolt 3 to be mounted or removed as required on the mast 6.

"Effect of the invention" When the invention as explained above is applied, the wall surface 5
and installation to the mast 6 can be properly achieved, and only a single mounting bracket 2 is required for this purpose. In other words, by using one mounting bracket 2 by inverting it, as described above, Although it is possible to form each mounting condition smoothly, the wall surface 8
In the mounted state, the curved surface 22 portion of the mounting bracket 2 is fitted into the curved fitting groove 18 of the mounting seat 11 to ensure accurate positioning and to form a precise mounting relationship. The setting relationship between the mounting bracket 2 and the mounting seat 11 is also stabilized, and in any case, a strong and stable installation is achieved, and the configuration of the mounting bracket 2 and the mounting seat 11 is simplified.
It has the effect of making its production easier, and is a highly effective idea in practical terms.
