Description

  The present invention relates to a floor joint device that covers joint portions of floor portions of left and right buildings.

  In the conventional floor joint device, a rotating member made of a round pipe material is fixed to the bottom surface of the rear end portion of the joint plate, the rotating member is supported by a crank-shaped support fitting, and the rear end portion of the joint plate A holding plate is installed to cover the gap between the bottom of the housing.

The floor joint device constructed in this way can absorb the shaking movement by sliding the tip of the joint plate for shaking movements where the joint part becomes narrower or wider, but in different longitudinal directions In the case of shaking, the contact resistance between the tip of the joint plate and the floor of one housing or the rotating member of the rear end of the joint plate and the support bracket is large, and the joint plate cannot be smoothly moved and damaged. There was a drawback of making it.
Japanese Patent No. 3189228

  In view of the conventional drawbacks as described above, the present invention can efficiently prevent the slide body from sliding and damaging efficiently even if the left and right housings swing in different longitudinal directions due to an earthquake or the like. An object of the present invention is to provide a floor joint device that can slide the joint plate safely even when the joint becomes narrow.

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-mentioned object, the present invention is supported by a floor surface on the joint portion side of one housing so that the tip portion covers a concave portion formed on the inclined surface on the opposite joint portion side, and on the joint portion side of the other housing In a floor joint device including a joint plate whose rear end portion is supported via a support member attached to the support member, the support member is attached to the other joint portion side housing so as to be rotatable at predetermined intervals in the horizontal direction. A plurality of rollers whose outer peripheral portions whose diameters on both ends are gradually expanded from the diameter of the central portion are arc-shaped and the bottom surfaces supported by the plurality of rollers are the same as the arcs of the plurality of rollers or A floor joint device is constituted by a support bar which is formed in a small-diameter arc and is fixed to the bottom surface of the rear end portion of the joint plate so as to be movable or vertically movable.

  As will be apparent from the following description, the present invention has the following effects.

(1) A plurality of circular outer peripheral parts whose diameters on both ends are gradually increased from the diameter of the central part attached to the other joint part side housing so as to be rotatable at predetermined intervals in the horizontal direction. A roller and a bottom surface supported by the plurality of rollers are fixed to or attached to the bottom surface of the rear end portion of the joint plate, which is formed in an arc having the same or a small diameter as the arcs of the plurality of rollers. The support bar attached to the bottom surface of the rear end of the joint plate is smoothly moved back and forth by multiple rollers when the left and right chassis shake in different longitudinal directions due to earthquakes, etc. It can be slid in the direction to absorb the shaking movement.
Therefore, it is possible to absorb different back-and-forth swing motions.

(2) When the joint portion is swung so as to be narrowed by (1), the lower end portion of the rear end portion of the joint plate rotates the arc-shaped portion of the plurality of rollers with the arc-shaped support bar. Thus, the tip of the joint plate can be smoothly rotated.
Therefore, when the joint portion becomes narrow, the joint plate can be smoothly rotated to absorb the shaking motion.

(3) According to the above (1), since the structure is simple, it can be easily installed.

(4) According to the above (1), if the circular arc of the outer peripheral portion of the plurality of rollers is formed into an arc with a corner portion on the joint portion side of the other casing as a fulcrum, the joint portion side of the other casing is used. The upper surface of the corner portion and the upper surface of the joint plate can be made substantially the same surface not only during normal times but also when the joint plate is rotated, and can be used safely.

(5) In the second and third aspects, the same effects as in the above (1) to (4) 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.

  In addition, by forming the circular arc of the outer peripheral part of the plurality of rollers 11 into an arc shape with the corner part 0 on the joint part 3 side of the other casing 2 as a fulcrum, the corner part 0 and the joint plate 7 Using the upper rear end as a fulcrum, the tip of the joint plate 7 can be rotated upward.

  In the case of the floor joint device 1 having the above structure, when the left and right housings 2 and 2 are swung in different front and rear directions due to an earthquake or the like, the rear end portion of the joint plate 7 supported via the plurality of rollers 11 and the support bar 13. Since the resistance is smaller than that of the tip portion, as shown in FIG. 8, the rear end portion of the joint plate 7 slides in the front-rear direction and absorbs the shaking motion.

When the left and right housings 2 and 2 swing so that the joint portion 3 is narrowed, the tip of the joint plate 7 is rotated upward along the inclined surface 4 of the concave portion 5 of one housing 2 as shown in FIG. While projecting in the direction of one of the housings 2 to absorb the swaying movement, the lower end portion of the rear end portion of the joint plate 7 is supported by the support bar 13 of the arc 12 and the arc shape of the outer peripheral portion of the plurality of rollers 11. The joint plate 7 can be smoothly slid to rotate the joint plate 7 smoothly.
