Description

  The present invention relates to a floor joint device for covering floor surfaces between left and right housings having both side walls provided through joint portions with a plurality of joint plates arranged in parallel.

Conventionally, floor joint devices in which the side walls are provided on the left and right housings absorb the shaking motions of the left and right housings in different front and rear directions. It is considered to absorb the swaying motion by getting into the plate.

However, if the left and right chassis sway in different longitudinal directions and the joint plates at both ends move in contact with the side walls of the left and right chassis, a gap is created between the left and right chassis walls, which is dangerous. It was.
nothing special

    In view of the conventional drawbacks as described above, the present invention can reliably prevent a danger that a gap is generated between both side walls of the left and right housings even if the left and right housings swing in different front and rear directions. It aims at providing the joint device for floors which can be used safely.

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 between the left and right housings having both side walls provided through the joints, even if the left and right housings are swung in different front and rear directions. An upper joint device using a joint plate that can absorb and when the left and right housings swing in different front and rear directions, one joint member housing that can cover a gap generated in the side wall portions of the left and right housings. A first end joint device using a stretchable plate, which has a distal end portion provided at a lower position of the upper joint device on both side walls and is always in contact with the other joint portion side housing so as to be movable in the front-rear direction; An extensible plate in which a tip provided at a lower position of the first end joint device on both side walls of the other joint side housing is always in contact with one joint portion housing so as to be movable in the front-rear direction. Second end using Constitute a floor for the joint device and ground equipment.

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

(1) When the left and right housings swing in different front and rear directions, the width of the upper joint plate in the front and rear direction is reduced by the side walls of both ends of the left and right housings to absorb the shaking motion. A gap is generated between the side walls of the first and second end joint devices, and the gap can be covered with the first end joint device and the second end joint device.
Therefore, even if the left and right housings swing in different front and rear directions, it is possible to reliably prevent a gap from being formed between the side walls at both ends of the left and right housings, and the device can be used safely.

(2) Since the first end joint device and the second end joint device may be installed on the side wall portions at both ends of the left and right housings, they can be installed easily.

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

The rear end portion that covers the joint portion 2 between the left and right housings 4, 4 having the walls 3, 3, 3, 4 is supported by a plurality of rollers 6 provided in the joint plate support recess 5 so as to be movable in the front-rear direction. When the tip part is supported by the joint plate slide support recess 8 formed on the inclined surface 7 on the anti-joint part side and swings in different front and rear directions due to an earthquake, the parts can overlap and absorb the swinging motion. The upper joint device 12 using the joint plate 11 having the guide rail 10 having the tip end portion of the inclined surface 9 and the lower end opening at the rear end portion, and the left and right housings, in the present embodiment. 4, 4 swings back and forth in different directions In this case, the lower side of the upper joint device 12 on both side walls 3 and 3 of one joint part side housing 4 capable of covering the gap generated in the side walls 3, 3, 3 and 3 of the left and right housings 4 and 4 First end joint devices 14 and 14 using an extendable cover body 13 whose tip portion provided at a position is always in contact with the other joint portion side housing 4 so as to be movable in the front-rear direction, and the other joint portion Extending and contracting that the tip provided at the lower position of the first end joint device 14, 14 on both side walls 3, 3 side of the side housing 4 is always in contact with one joint side housing 4 so as to be movable in the front-rear direction. It comprises a second end joint device 16, 16 using a possible cover body 15.

The seven joint plates 11, 11, 11, 11, 11, 11, 11 of the upper joint device 12 are attached so that the joint plates 11, 11 at both ends always contact the side walls 3, 3, 3, 3. The inner side surface is biased by the biasing springs 17, 17 and is formed into inclined surfaces 18, 18 whose lower portions protrude outward.
The joint plates 11, 11 adjacent to the joint plates 11, 11 at both ends are formed on the inclined surfaces 19, 19 in surface contact with the inclined surfaces 18, 18, and the adjacent joint plates 11, 11 are formed. And the hinge plates 20 and 20 are installed so that the joint plates 11 and 11 side of both ends can be rotated upward.
The joint plates 11, 11, 11, 11, 11 arranged in parallel other than the joint plates 11, 11 at both ends may be connected using a hinge member.

  As shown in FIG. 4, the first end joint devices 14, 14 are arranged in the left-right direction at the lower position of the upper joint device 12 on the both side walls 3, 3 side of one joint portion side housing 4. Guide cylinders 21, 21, 21, 21, which are provided in a parallel state with a predetermined interval as much as possible, and a coil spring 22 provided in the guide cylinders 21, 21, 21, 21, 21, 22, 22, 22, 22, which is urged so as to always protrude, is provided with a roller 23 that is pressed against the other joint-side housing 4 and is slidable in the front-rear direction, and covers a gap generated during an earthquake. It is comprised by the slide support body 24, 24, 24, 24, 24 which comprises the cover body 13 which can be carried out.

  As shown in FIG. 5, the second end joint device 16, 16 is pivoted to a lower position of the first end joint device 14, 14 on the side walls 3, 3 side of the other joint side housing 4. The guide cylinders 25, 25, 25, 25, 25 are provided in a parallel state with a predetermined interval and a gap as much as possible so that the center direction is the left-right direction, and the guide cylinders 25, 25, 25, 25, 25 are provided. The coil springs 26, 26, 26, 26, 26 are urged so that they always protrude, and are provided with a roller 27 that is pressed against one joint side housing 4 and can slide in the front-rear direction. It is composed of slide supports 28, 28, 28, 28, 28 constituting a cover body 15 that can cover a gap that sometimes occurs.

  When the floor joint device 1 having the above-described structure is shaken in the left-right direction by the earthquake, the tip portions of the joint plates 11, 11, 11, 11, 11, 11, 11 are shown in FIGS. 7, the joint plate slide support recess 8 is slid in the left-right direction to absorb the shaking motion.

When the left and right housings 4 and 4 are swung in different longitudinal directions due to the earthquake, the joint plates 11 and 11 at both ends of the upper joint device 12 are connected to the side wall 3 of the one housing 4 and the other as shown in FIGS. The width dimension of the upper joint device 12 in a state in which the adjacent joint plates 11, 11 ride on the joint plates 11, 11 at both ends is reduced by the side walls 3 of the casing 4.
For this reason, a gap is generated between the side wall 3 of one housing 4 and the outer side portion of the side wall 3 of the other housing 4, and as shown in FIGS. 8 and 10, it is covered with the first end joint devices 14 and 14. The portions that cannot be covered with the first end joint devices 14, 14 are covered with the second end joint devices 16, 16 and outside the side walls 3, 3, 3, 3 of the left and right housings 4, 4. It is possible to reliably prevent a gap that threatens safety from occurring in the portion.
