Description

  The present invention relates to a spacer member that adjusts a gap between a back surface and a wall surface of an electrical / electronic equipment storage box when the back surface of the electrical / electronic equipment storage box is fixed to a wall surface with bolts and nuts.

  When fixing the back of the electrical and electronic equipment storage box to the wall with bolts and nuts, the wall is uneven or distorted, and the gap between the back of the four corners fixed on the back of the electrical and electronic equipment storage box and the wall is not uniform. In this case, if the back surface is fixed to the wall surface as it is, there is a problem that the back surface is distorted and the electrical / electronic equipment storage box is deformed to cause a malfunction such as a door opening / closing failure.

    Therefore, as a conventional example of Japanese Patent Application Laid-Open No. 2000-91755 (Patent Document 1), there is a technical means for performing a gap adjustment by attaching a flat washer to a bolt and inserting a steel plate between the wall surface. It is disclosed. Further, the invention according to this gazette adjusts the gap formed between the back surface and the wall surface of the box body by screwing the spring-like member from the back side to the back surface and the wall surface through the bolt insertion hole. It was done by adjusting the amount.

However, in the case of adjusting the gap by attaching the above-described flat washer to the bolt, the flat washer must be attached to the bolt before attaching the electric / electronic device storage box to the wall surface, and there is an error after tightening the bolt. In such a case, there is a problem that the electric and electronic equipment storage box must be removed from the wall surface. Moreover, what is performed by inserting an iron plate between the wall surfaces has a problem that it is troublesome to support the iron plate when tightening the bolt. Furthermore, what is performed with a spring-like member is expensive because the spring-like member is special.

  Further, as described above, since the engaging recess is positioned above the center of gravity of the spacer member when engaged with the bolt shaft portion, the spacer member engages the bolt shaft portion with a good balance by its own weight and falls. Thus, the bolt and nut can be tightened without holding the space member with fingers. Further, even when a plurality of spacer members are mounted by the gap, there is no possibility that the spacer members interfere and fall.

  Further, if the engagement recesses that engage with the bolt shaft portions are provided in three directions, that is, the opposite edge of the end opening of the notch portion and the both side edges of the notch portion, the mounting recess is mounted from the side surface side of the electrical / electronic device storage box. However, workability is good because it is mounted in the same position.

Next, a preferred embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a spacer member. The spacer member 1 adjusts the gap between the back surface 21 and the wall surface (A) when the back surface 21 of the electric / electronic device storage box 2 is fixed to the wall surface (A) by the bolt 3 and the nut 4. Is for.

  As shown in FIG. 3, the spacer member 1 has a notch portion 12 through which a bolt shaft portion 31 is inserted from an opening 11 provided at an end portion of a thin spacer member body 10 and a bolt shaft on the notch portion 12. The engaging recess 13 that engages with the portion 31 is provided at a position that is located above the center of gravity (G) of the spacer member 1 when engaged with the bolt shaft portion 31.

  In addition, the engagement recess 13 provided at a position located above the center of gravity (G) of the spacer member 1 is formed in three directions: an opposing edge 12a of the opening 11 of the notch 12 and both side edges 12b and 12b of the notch 12. Even if it is mounted from the side as well as from the upper side of the electric / electronic equipment storage box, it is mounted at the same position, so that workability is good. The engaging recesses 13, 13, 13 provided in these three directions are positioned above the center of gravity (G) of the spacer member 1 when the bolt shaft portion 31 is engaged, as shown in FIGS. 3 to 5. Of course.

  The spacer member 1 has a quadrangular shape as shown in the figure, and is composed of an opposing edge 12a that is opposite to the end provided with the opening 11 of the notch 12 and both side edges 12b and 12b that are both sides of the notch 12. The engagement recess 13 is provided in the direction, and each end side of the spacer member 1 and the side surface of the electrical / electronic device storage box 2 are parallel to each other, and the spacer member 1 does not protrude from the side surface of the electrical / electronic device storage box 2.
