Description

  The present invention relates to a joint cover device that covers a space between wall surfaces and a ceiling via joint portions.

  As this type of conventional joint cover device, a device that covers the joint portion with a joint cover that is twice the width of the joint portion is used.

However, such a joint cover device requires a space on one side where the joint cover that slides twice the width of the joint portion needs to be moved. If such a space cannot be secured, it cannot be installed. The joint cover has a large size and a high cost.
Japanese Patent No. 3139888

  SUMMARY OF THE INVENTION In view of the above-described conventional drawbacks, the present invention provides a joint cover device that can absorb different shaking motions in the front-rear and left-right directions between the left and right housings and can cover the joint without causing a gap. The purpose is that.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention provides a fixed-side support bar that is rotatably attached to one case-side case via a hinge member, and the other case that faces the fixed-side support bar. A fixed joint plate pivotally attached to a hinge member, and one end portion pivotally supported at a rear side portion of the fixed joint plate on the free end side, and the other end portion is supported on the fixed side plate. At least two telescopic links that are pivotally supported by the bar and have a plurality of pivotal support portions at regular intervals even if they are expanded and contracted, and a plurality of pivotal support portions of the at least two elastic link links in parallel. A plurality of movable support bars pivotally supported by the plurality of movable support bars, and a crank-shaped rear end portion is always attached to the plurality of movable support bars in a biased state in the movable support bar direction, and a front end portion thereof is the fixed-side joint plate. Can slide to adjacent members It constitutes a joint cover device at a plurality of joint cover member which is overlapped supported.

  As is clear from the above description, the present invention has the following effects.

(1) A fixed-side support bar rotatably attached to one housing on the joint portion side via a hinge member, and the other housing at a portion facing the fixed-side support bar is rotated via a hinge member A fixed joint plate that can be attached, and one telescopic end of the fixed joint plate that is pivotally connected to the rear end of the fixed end joint plate, and the other end is pivotally supported by the fixed support bar. Even at least two or more telescopic links having a plurality of pivots at equal intervals at all times, and a plurality of pivots pivoted to be parallel to the plurality of pivots of the at least two telescopic links A movable support bar and a plurality of movable support bars, the crank-shaped rear end portion is always attached in a biased state toward the movable support bar, and the front end portion is slidable to the fixed joint plate or an adjacent member. Multiple eyes supported by overlapping Because it is composed of a cover member, even if one housing and the other housing swing in different directions in the front / rear and left / right directions due to earthquakes, etc., due to the rotation of the stationary support bar, stationary joint plate and expansion / contraction of the expansion / contraction link, The swaying can be absorbed by the sliding movement of the plurality of movable support bars and the plurality of joint cover members.
Therefore, the joint can be reliably covered.

(2) By (1), it can be installed between joints.
Therefore, it is possible to achieve a reduction in size and size as compared with a conventional case where a joint cover that is approximately twice the joint portion is used.

(3) According to the above (1), since the plurality of joint cover members are always attached in a biased state toward the movable support bar, the plurality of joint cover members are always kept in a state of being in close contact with each other. be able to.
Therefore, it is possible to reliably cover without generating a gap between the plurality of joint cover members, and since the surface is almost flat, it is possible to efficiently generate a large gap between the other cover members. And can be used safely.

(4) In claim 2, the same effects as in the above (1) to (3) can be obtained.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.
