Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a structure for mounting a unit by fitting it into an opening.

[Prior art]

When mounting the unit by fitting it into the opening formed in the base from the lower side, in order to prevent the unit from falling out of the opening and dropping downward, a locking tool is attached to the edge of the opening on the lower surface of the base material. Need to be installed.

[Problems to be solved by the device]

However, in this case, since the locking tool is exposed on the lower surface of the base body, there is a possibility that the locking tool may damage the appearance. Further, when it is difficult to fix the screw such as when the base is located at a high place, it is difficult to attach the unit to the opening. The present invention has been made in view of the above points, and an object of the present invention is to provide a unit mounting structure in which there is no possibility that the locking tool is exposed on the lower surface and the unit is easily mounted in the opening. It is a thing.

[Means for Solving the Problems]

The unit mounting structure according to the present invention comprises a fixed piece 1 and a fixed piece 1.
From the upper end of the rising piece 2 and the inclined spring piece 3 extending downward from the fixed piece 1 to the opposite side.
A locking tool 5 including a locking piece 4 extending from the lower end of the tilted spring piece 3 to the fixed piece 1 side is formed, and the tilted spring piece 3 is locked to the end edge of the upper surface of the unit 6. The fixing piece 1 of the locking tool 5 is fixed so that the piece 4 projects outward from the edge of the unit 6, and the plurality of locking tools 5 are attached to the unit 6, and the unit 6 is attached to the base 7 holding the unit 6. The opening 8 having substantially the same size as that of the upper surface of the
And the lower surface of the locking piece 4 of the locking tool 5 is locked to the upper edge of the opening 8.

[Action]

In the present invention, when the unit 6 is fitted into the opening 8 of the base body 7 from below, the tilted spring piece 3 of the locking tool 5 is inserted.
After the bending, the locking piece 4 of the locking tool 5 is locked to the upper edge of the opening 8, and the unit 6 is attached to the opening 8 with the locking tool 5 fixed to the upper surface of the unit 6. You can

【Example】

Hereinafter, the present invention will be described in detail with reference to embodiments. The locking tool 5 has a rising piece 2 extending at one end of the fixing piece 1 which rises and rises on the side opposite to the fixing piece 1, and an inclined spring piece 3 is provided at the upper end of the rising piece 2 to the opposite side of the fixing piece 1. It is formed so as to extend so as to incline, and further the locking piece 4 is formed at the tip of the inclined spring piece 3 so as to extend to the fixed piece 1 side. It is formed in an arc shape that forms a part. The locking tool 5 is formed by bending a metal plate material, but the front end of the locking piece 4 has a narrow width.
As shown in the figure, a slit hole 12 is formed in the rising piece 2 at a position corresponding to the tip of the locking piece 4. FIG. 2 shows an embodiment in which the storage box 6a is used as the unit 6 and the wall cabinet 7a fixed to the upper part of the wall surface in the room is used as the base body 7, respectively. Box 6a
It shows an embodiment in which is attached. That is, first, the plurality of locking tools 5 are attached to the edge portions of the top surface of the top plate 13 of the storage box body 6a. The locking tool 5 can be attached by fixing the fixing piece 1 with a screw, but as shown in FIG. 3, the inclined spring piece 3 and a part of the locking piece 4 are outside the edge of the top plate 13. The locking tool 5 is attached so as to project inward. At this time, approximately half of the locking piece 4 projects from the edge of the top plate 13, and the lowest part of the lower surface of the locking piece 4 is at substantially the same level as the lower surface of the fixed piece 1, This part of the locking piece 4 is in contact with the edge of the plate 13. On the other hand, on the lower surface of the wall cabinet 7a, there is formed an opening 8 having substantially the same shape and size as the upper surface of the top plate 13 of the storage box 6a. Then, as shown by the arrow in FIG. 2, when the storage box body 6a is inserted into the opening 8 of the wall cabinet 7a from below, the inclined spring piece 3 of the locking tool 5 first comes into contact with the lower edge of the opening 8. As a result, the inclined spring piece 3 is flexibly deformed toward the fixed piece 1 side, and accordingly, the locking piece 4 is also rotated toward the fixed piece 1 side. Since the locking piece 4 is formed in an arc shape, this rotation of the locking piece 4 is smoothly performed. At this time, as shown by the arrow in FIG. 3, the tip of the locking piece 4 is inserted into the slit piece 12 of the rising piece 2 so that the rising piece 2 does not interfere with the rotation of the locking piece 4. The bending of the inclined spring piece 3 allows the locking tool 5 to pass through the opening 8. When the lower end of the inclined spring piece 3 reaches above the upper edge of the opening 8, the inclined spring piece 3 is moved. Since the force of pressing is released, the inclined spring piece 3 returns to its original state, and the locking piece 4 is locked to the upper edge of the opening 8 as shown in FIG. In this way, the locking piece 4 of the locking tool 5 is locked to the upper edge of the opening portion 8, so that the storage box body 6a as the unit 6 is placed in the opening portion 8 of the wall cabinet 7a as the base body 7.
It can be installed by fitting. In this case, since the locking tool 5 is provided on the upper surface of the unit 6, the locking tool 5 cannot be seen from below. Further, by forming the locking piece 4 of the locking tool 5 in an arc shape as in the above-described embodiment, the upper surface of the base 7 and the upper surface of the unit 6 are at substantially the same level as shown in FIG. By setting the thickness of the base 7 and the thickness of the unit 6 to be equal to each other, it is possible to make a flat state between the lower surface of the base 7 and the lower surface of the unit 6 without a step. FIG. 5 shows an embodiment in which the ceiling 7b is used as the base 7 and the inspection port lid 6b is used as the unit 6. The inspection port lid 6b is fitted into the opening 8 which is the inspection port formed in the ceiling 7b. FIG.
In this case, push the inspection lid 6b upward to open the opening 8
Can be opened.

[Effect of device]

As described above, in the present invention, the fixing piece, the rising piece rising from the fixing piece, the inclined spring piece extending downward from the upper end portion of the rising piece and the lower end of the inclined spring piece, and the lower end of the inclined spring piece. Forming a locking tool having a locking piece extending from the portion to the fixed piece side, and the inclined spring piece and the locking piece projecting outward from the edge of the unit at the edge of the upper surface of the unit. Fix the fixing piece of the locking tool to the unit, attach the plurality of locking tools to the unit, fit the unit into the opening of the base from below, and engage the lower surface of the locking piece of the locking tool with the upper edge of the opening. Since it is stopped, the unit can be attached to the opening with the fastener fixed to the upper surface of the unit, and it can be attached with the fastener that is not exposed downward, Not to damage the It is possible to attach the unit even in a high place where it is difficult to hit with a screw, and it is possible to attach the unit without difficulty, and when the unit is fitted from below into the opening of the base body, the inclination of the locking tool After the spring piece bends, the locking piece is locked to the upper edge of the opening, so that the work of mounting the unit can be easily performed.
