Description

  The present invention relates to a floor joint device for covering joint portions between left and right floor frames installed via angle joint portions.

A rectangular joint plate is arranged at the corner portion of the conventional angle joint portion, or a trapezoidal shape that protrudes so that one side portion of the joint plate located at the corner portion contacts is used. Yes.

For this reason, when the left and right floor frames are swung in different directions, the former has the disadvantage that the corner joint plate is supported by a single pin, so that an unreasonable load is applied and is easily damaged.
In the latter case, the joint plate at the corner portion has a triangular shape at the tip of the one side that comes into contact with the corner plate, and it is dangerous to protrude, and the tip has a triangular shape.
Japanese Patent No. 3662172

    In view of the above-described conventional drawbacks, the present invention provides a floor joint device that can prevent an excessive load from being applied to a corner joint plate even at an angle joint, and can be used safely. It is an object.

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 joint plate supporting recess having a corner portion formed on the joint portion side of the inner floor frame provided through the angle joint portion and having a trapezoidal upper profile shape, A corner plate formed on the joint portion side of the outer floor frame at a portion corresponding to the joint plate support concave portion has a trapezoidal upper contour shape, and a joint plate slide support concave portion having an inclined surface on the opposite joint portion side, and the corner joint plate A corner joint plate, which is supported by the support recess so as to be pivotable upward with a pin and the tip part covers the corner joint plate slide support recess, and both side surfaces of the corner joint plate, A tip portion is supported by a pin so as to be pivotable upward with a pin on the joint plate support recess formed so that one side surface abuts, and the other side surface supported so that the tip portion covers the joint plate slide support recess is up and down. Neighborhood Right and left joint plates in the shape of a right trapezoid, and left and right joints attached to one side surface of the left and right joint plates through springs so as to contact both side surfaces of the corner joint plate The joint device for floors is comprised with the plate connector.

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

(1) A joint plate support concave portion having a trapezoidal upper corner shape formed on the joint portion side of the inner floor frame provided through the angle joint portion, and a portion corresponding to the joint plate support concave portion The corner portion formed on the joint portion side of the outer floor frame has a trapezoidal upper profile shape. A corner joint plate that is supported so as to be pivotable upward and whose tip is supported so as to cover the corner joint plate slide support recess, and is formed so that both sides and one side of the corner joint plate are in contact with each other. The tip of the joint plate support recess is supported by a pin so as to be pivotable upward, and the tip is supported so as to cover the joint plate slide support recess. Joints And left and right joint plate connectors attached to one side surface of the right and left joint plates and connected via springs so as to contact both side surfaces of the corner joint plate. Therefore, the corner joint plate can prevent the right and left joint plates arranged on both sides of the corner joint plate from becoming large, and the tip portion can be prevented from becoming dangerous.

(2) According to the above (1), since the width dimension of the front end portion of the corner joint plate does not need to be set large, it can be easily supported by the pin at the rear end portion.
