Description

  The present invention relates to a floor joint device for covering a joint portion between left and right floor frames provided via a joint portion.

The conventional floor joint device is formed with recesses in the left and right housings on the joint portion side so as to cover the joint portion, and a shallow plate-shaped joint plate is installed in the recess, and when the joint portion becomes narrow, the joint plate is moved upward. A moving mechanism for projecting is provided.
For this reason, since the joint plate protrudes upward when the joint portion becomes narrow, there is a risk that the joint plate is heavy and cannot be moved smoothly because the joint plate is heavy.
nothing special.

  In view of the above-described conventional drawbacks, the present invention prevents the joint portion from protruding upward even when the joint portion becomes narrow, and smoothly follows the large joint portion dimensional change to absorb the movement. An object of the present invention is to provide a floor joint device that can be used.

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 provides at least two or more extendable support bodies pivoted at both ends at the joint part portions of the left and right housings provided via the joint parts. A plurality of bar members juxtaposed at a predetermined interval on at least two or more extendable supports, and both ends where the plurality of bar members are pivotally supported by the pivotal support are the bar members or joints on both ends. A plurality of pantograph-like expansion links pivotally supported by the left and right housings, and a plurality of joints covering the expansion and contraction gaps between the plurality of bar members respectively fixed to the plurality of bar members The joint device for floors is comprised with the plate.

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

(1) At least two or more extendable supports can be expanded and contracted according to the expansion and contraction of the joint.
Therefore, a plurality of bar members supported in parallel on the support at a predetermined interval can be expanded and contracted by the pantograph-shaped expansion link, and the movement can be absorbed without protruding to the upper surface.

(2) According to the above (1), since the central portion of the plurality of bar members is pivotally supported by the central member of at least two or more extendable supports, at least two or more pantograph-like expansion links are used. It is possible to prevent the plurality of bar members from moving unnecessarily in the front-rear direction.
Therefore, it can be used safely without generating a large gap.

(3) According to the above (1), it is composed of at least two or more stretchable supports, a plurality of bar members, and at least two or more pantograph-like stretch links, so that the structure is simple and conventional. This eliminates the need for a large and heavy joint plate and facilitates transportation and installation.

At least two or more pantograph-like telescopic links 8 pivotally supported by the bar members 6 and 6 or the left and right floor frames 3 and 3 on the joint side. It is composed of a.

  The extendable supports 5 and 5 are a pair of U-shaped support bars in which the front end portion of which the hinge members 9 and 9 are attached to the rear end portion overlaps the size of about one third of the joint portion 2. 10 and 10, angled support pieces 11 and 11 formed at lower and upper portions supporting the pair of support bars 10 and 10 so as to be slidable, and the reverse of inserting the support pieces 11 and 11 A support mechanism 13, 13 composed of U-shaped guide pieces 12, 12, a pair of racks 14, 14 fixed to opposed surfaces of the pair of support bars 10, 10, and the pair of support bars 10 The central member 4 is composed of a pinion 15 meshing with the pair of racks 14 and 14 in the center of 10 and a pivot pin 16 attached to the pinion 15 as required, and the pinion 15 of the central member 4 is dropped. To prevent As shown, the pinion support pieces 17 and 17 are fixed to the inner wall surfaces of the pair of support bars 10 and 10 at the lower position of the pinion 15.

  The plurality of bar members 6 are made of square pipe material, and the bar member 6 located at the center is pivotally supported by the pivot pins 16 and 16 of the extendable supports 5 and 5, and the bar members at both ends. 6 and 6 are pivotally supported by pivot pins 18, 18, 18 and 18 at the rear ends of the pair of bar members 6, 6, 6 and 6.

  The floor joint device 1 having the above-described configuration is normally provided with a pivotal support portion of at least two or more pantograph-like stretchable links 8 and 8 so as to have a predetermined interval between at least two or more stretchable supports 5 and 5. 7, a plurality of bar members 6, 6, 6, 6, 6, 6, 6 that are pivotally supported by a pivotal pin 18 are supported, and the joint portion can be covered like a slat.

  When the joint portion 2 is widened or swung in the lateral direction to be narrowed due to an earthquake or the like, at least two or more extendable supports 5 and 5 and at least two or more support members as shown in FIGS. The pantograph-like expansion and contraction links 8 and 8 are expanded and contracted to move the plurality of bar members 6, 6, 6, 6, 6, 6, 6 to expand and contract at equal intervals to absorb the shaking motion. it can.

Further, in the case of swinging in different front and rear directions, as shown in FIG. 10, at least two or more supports 5 and 5 are rotated in the front and rear directions by the hinge members 9 and 9, and at least two or more pantographs are used. Since both ends of the telescopic links 8 and 8 are pivotally supported by the pivot pins 18 and 18, they rotate in the same direction.
Therefore, the plurality of bar members 6, 6, 6, 6, 6, 6, 6 are also slid and moved so that the end portions are inclined in different front-rear directions while maintaining equal intervals. Absorb.
When the shaking motion stops, the support bodies 5 and 5, the telescopic links 8 and 8, and the plurality of bar members 6, 6, 6, 6, 6, 6, 6 are automatically returned to the original state.
