Abstract

PROBLEM TO BE SOLVED: To provide a joint device for a floor capable of smoothly moving a joint plate having weight in an earthquake, by surely preventing an addition of a large load or damaging to an engaging pin for supporting the joint plate, in the joint plate used in a vehicle traveling place.SOLUTION: The joint device for a floor is constituted of a joint plate slide support recess 5 formed on a floor surface on the joint part side of one floor skeleton 3, a joint plate support recess 7 formed on the floor surface on the joint part side of the other floor skeleton, a joint plate 9 provided in this joint plate support recess, at least a pair of engaging cylinders 13 fixed to the joint part side of the other floor skeleton so that an upper surface is positioned in a lower part than an inner bottom surface of the joint plate support recess of the other floor skeleton 3 and at least a pair of engaging pieces 14 provided on a bottom surface near a rear end part of the joint plate.

Description

  The present invention relates to a floor joint device that covers a joint portion between left and right floor frames provided via a joint portion so that a vehicle or the like can pass therethrough.

  Conventionally, this type of floor joint device is composed of a joint plate slide support recess formed on an inclined surface on the joint portion side of one floor housing, and the other floor housing facing the joint plate slide support recess. A joint plate support recess formed on the joint portion side and an engagement pin formed in the joint plate support recess engage with a rear end portion supported by the joint plate support recess, and a leading end portion of the joint plate slide It is comprised with the joint plate supported so that a support recessed part may be covered.

  However, 400 kg to 500 kg of joint plates are used in places where vehicles or the like travel on the joint plates.

  In such a heavy joint plate, if the joint is narrowed by an earthquake, or the left and right floor frame swings so as to widen, the joint plate will be pushed by the other floor frame if the joint is narrowed. There is no problem, but when the joint portion becomes wide, there is a disadvantage that a heavy joint plate is pulled by the engagement pin, and a large load is applied only to the engagement pin and is easily damaged.

  The present invention is a joint plate used in a place where a vehicle or the like travels in view of the conventional drawbacks as described above, and even if the joints of the left and right floor frames are swung so as to narrow or widen due to an earthquake. A floor that can reliably prevent a large load from being applied to or damage the engaging pin that supports the joint plate, and can move a heavy joint plate smoothly during an earthquake. It aims to provide a joint device.

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 a joint plate slide in which the joint surface side of the left and right floor housings provided via the joint portion is formed on the joint surface side of the floor housing on the side opposite to the joint surface. A support recess, a joint plate support recess formed on the floor surface of the other floor case facing the joint plate slide support recess, and at least a pair of engagement pins provided in the joint plate support recess The joint plate storage box at the rear end engages and is supported by the joint plate support recess, and the joint plate is supported so that the front end covers the joint plate slide support recess, and the other floor At least a pair of engagement cylinders fixed to the joint portion side of the other floor casing such that the upper surface is located below the inner bottom surface of the joint plate support recess of the casing; If the left and right floor frames move so that the joints are kept in an engaged state even when the joints are narrowed due to an earthquake and the joints are turned upward due to an earthquake, and the joints are widened, The floor joint device includes at least a pair of engagement pieces provided on the bottom surface near the rear end of the joint plate so that the plate can be pulled with minimum force applied to the at least one pair of engagement pins. Is configured.

As is clear from the above description, the present invention has the following effects.
(1) According to claim 1, when the joint portion becomes narrow due to an earthquake and the joint plate becomes wider after the tip of the joint plate rides on one floor case, and returns to the original position, the other floor case The joint plate can be returned to the original position by at least a pair of engagement pieces engaged with at least a pair of engagement cylinders fixed to the joint portion side of the joint plate.
Therefore, the joint plate can be returned to the original position without applying a large load to at least the pair of engagement pins, and damage to at least the pair of engagement pins can be effectively prevented.
(2) When the joint portion becomes narrow due to the earthquake according to (1), at least a pair of engagement pins and an engagement pin storage box are provided so that the rear end portion of the joint plate can be pushed by the wall surface of the joint plate support recess. By disposing, it is possible to prevent a large load from being applied to at least the pair of engagement pins.
(3) According to the above (1), the joint plate is held by the engagement pin storage box, the engagement pin, the engagement piece, and the engagement cylinder. Can slide.
(4) In claim 2, the same effects as in the above (1) to (3) can be obtained, and when the joint plate is returned to the original position, at least the lower ends of the pair of engagement pieces are at least inside the pair of engagement cylinders. Since it is in contact with the wall surface, a force that moves the tip of the joint plate downward is applied, and the joint plate can be safely slid.
