Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a structure for attaching a casing in which a safe is housed to a base.

[Prior art]

For example, some public telephones are used by being installed at the front of a store, and traditionally these have been installed by attaching the housing 1 to a base 2 outside the store when the store opens, as shown in Figure 1. There is.

However, in the conventional installation of the casing 1 to the base 2, the screw 4 is screwed into the base 2 through the washer 3, and the removal is done by unscrewing the screw 4. Because it is done,
This has the disadvantage that the work of installing and removing the housing 1 is complicated.

[Summary of the idea]

The present invention was developed in view of these circumstances, and has an extremely simple structure in which an engagement mechanism is provided between the base and the safe that engages in a direction that restricts the movement of the casing when the safe is stored. Installing the casing,
An object of the present invention is to provide a structure for attaching a casing to a base, which allows easy removal work. Hereinafter, the configuration and the like will be explained in detail by referring to embodiments shown in the drawings.

〔Example〕

FIG. 2 is an exploded perspective view showing a structure for attaching a housing to a base according to the present invention, and FIG. 3 is a sectional view taken along the line taken in FIG. 2. In these figures, the reference numeral 11 indicates a box-shaped bracket, and a screw 13 is attached to the base 12.
A so-called pothole 14 consisting of a large hole 14a and a small hole 14b is bored in the upper part. Reference numeral 15 designates a phone case having a safe storage chamber 16 therein, and body parts 17a and 1 that engage with the large hole 14a and the small hole 14b, respectively, on the bottom surface.
A collar 17 with a diameter 7b is provided between two positions in the direction of the surface of the base 12, that is, a large hole 14a and a small hole 14b.
The bracket 11 on the base 12 is removably mounted on the bracket 11 by moving between the brackets. Further, a seat member 18 made of a flexible material such as rubber is provided at the bottom corner of the housing 15. Reference numeral 19 denotes a safe for storing coins, which opens into the safe storage chamber 16 by moving in a direction perpendicular to the moving direction of the housing 15.
It is stored inside. Reference numeral 20 denotes an engagement mechanism that is engaged when the safe 19 is stored, and includes hook-shaped engagement grooves 21 and 22 drilled in the bottom of the casing 15 and the top of the bracket 11, respectively, and a collar on the casing 15. 23 and a locking plate 25 slidably provided by screws 24, and is provided between the base 12 and the safe 19. This engagement mechanism 20 is a locking plate 2 which is an engagement part on the side of the safe 19.
5 has one end facing inside the safe storage chamber 16 and the other end facing inside the bracket 11, and is an engaging groove 21, 22 which is an engaging part on the base 12 side, and restricts movement of the housing 15 between the two positions. It is configured to engage in the direction of That is, when the safe 19 is in the stored state, the locking plate 25 is engaged with the grooves 21a and 22a extending in a direction perpendicular to the moving direction of the housing 15. Note that 26 is a printed circuit board on which electronic components 27 are mounted.

Therefore, in order to attach the housing 15 to the base 12, the collar 17 is first inserted into the large hole 14a and the housing 15 is placed on the bracket 11. Next, as shown in FIG. 4, it moves toward the small hole 14b of the housing 15 and locks onto the bracket 11. At this time, the housing 15
is fixed with respect to the arrow Y direction. Then, the safe 19 is stored in the safe storage chamber 16. At this time, the fifth
As shown in the figure, the locking plate 25 is attached to the housing 1.

21b, and the housing 15 is fixed in the direction of the surface of the base 12 and in the direction perpendicular to this surface. In this way, the housing 15 can be reliably attached to the bracket 11, that is, the base 12.

In this embodiment, an engagement mechanism consisting of engagement grooves 21, 22 and a locking plate 25 is shown, but the present invention is not limited to this, and FIGS. As shown, an engagement mechanism 20 consisting of engagement holes 28 and 29 formed in the housing 15 and the bracket 11, and a hook-shaped locking part 30 provided on the back surface of the safe 19 is similar to the embodiment. It has the effect of In this case, safe 19
By storing the engaging holes 28 and 29, which are the engaging parts on the base 12 side, and the locking part 3, which is the engaging part on the safe 19 side.
0 is engaged. Further, as shown in FIG. 8, this engagement mechanism 20 consists of engagement grooves 31 and 32 provided in the safe 19 and the casing 15, and an engagement piece 33 formed in the bracket 11 by cutting and bending. ,
Furthermore, as shown in FIG.
5, 36 and a spring piece 37 attached to the back side of the bracket 11.

[Effect of idea]

As explained above, the present invention includes a casing that is removably placed on a base and a safe that is stored in the safe storage chamber of the casing. An engagement mechanism that engages in the direction that restricts body movement is provided between the base and the safe, eliminating the need for screws that were previously required to attach the case to the base.
The housing can be installed and removed extremely easily.
