Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ceiling joint cover that covers joints of ceiling portions of right and left buildings installed via joints.
[0002]
[Prior art]
This type of conventional joint cover changes the joint dimensions during an earthquake by sliding both ends of the joint cover body to the ceiling frame of the left and right buildings or rotating one end indoors. It has a structure that can absorb the swaying motion.
[0003]
[Problems to be solved by the invention]
In the conventional joint cover, since both ends of the joint cover body slide on the joint on the side of the joint, the sliding movement amount must be secured, and the joint cover becomes large, and it is difficult to mount the joint on the ceiling decorative material. There is a drawback that both ends of the joint cover main body protrude into the room and become unsightly.
Further, the joint cover having a structure in which one end of the joint cover main body is rotated to the indoor side has a drawback that it is dangerous because the joint cover projects indoors.
[0004]
In view of the above-mentioned conventional disadvantages, the present invention always keeps the joint cover body installed between joints in a substantially horizontal state, rotates when the joints become narrow, absorbs the swinging motion, and stops the swinging motion. The object is to provide a ceiling joint cover that can be automatically returned to the original state and can be used safely.
[0005]
The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are merely for explanation and do not limit the technical scope of the present invention.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a pair of right and left ceiling frames on the joint portions of left and right buildings installed via joints, which are fixed in a substantially horizontal state in the front-rear direction. A rail, at least two or more support bars slidably mounted at both ends arranged in an inclined state on the pair of rails, and an upper end substantially at the center of the at least two or more support bars; A suspended rod attached thereto, a joint cover main body covering the joint formed at the lower end portion of the suspended rod, the center portion of which is rotatably attached to the lower end thereof at an inclined surface in the opposite direction; Left and right guide members fixed to the left and right ceiling frames, the inclined surfaces of which are in contact with the inclined surfaces at both ends of the joint cover main body, the joint covers being in a substantially horizontal state, and the joint cover main body Always Crucible and held in a horizontal state, is constituted by a horizontal holding mechanism ceiling joint cover without blocking the rotation of the joint portion is pressed pressed by the left and right guide members becomes narrower.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.
[0008]
In the first embodiment of the present invention shown in FIGS. 1 to 6, reference numeral 1 denotes a joint 2 between left and right ceiling frames 3a, 3a of right and left buildings 3, 3 installed via a joint 2. The ceiling joint cover 1 of the present invention installed between the joint portions 2, wherein the ceiling joint cover 1 is provided at a position near the upper portion of the left and right ceiling frames 3 a, 3 a in a substantially horizontal state in the front-rear direction. A pair of rails 5, 5 fixed by screws 4 and the like, and rollers 6, 6, which are disposed on the pair of rails 5, 5 at a substantially 45 degree inclination, are slidably mounted. At least two or more support bars 7, 7; suspension rods 8, 8 each having an upper end attached to a substantially central portion of the at least two or more support bars 7, 7; At the lower end of 8 through the mounting brackets 9 A joint cover body 12 covering the joint part 2 having both ends movably mounted on opposite inclined surfaces 10 and 11, and inclined surfaces 10, 11 at both ends of the joint cover body 12; The right and left guide members 15 and 16 fixed to the left and right ceiling frames 3a and 3a with which the joint cover main body 12 formed with the contacting inclined surfaces 13 and 14 contact in a substantially horizontal state, and the joint cover main body 12 A horizontal holding mechanism 17 which is always held almost horizontally and the joint portion 2 is narrowed by a shaking motion such as an earthquake or the like, and is not prevented from rotating by being pressed by the left and right guide members 15 and 16. Have been.
[0009]
As shown in FIG. 4, the mounting bracket 9 is a plate-like base plate having screw insertion holes 19, 19 formed at portions near both ends by screws 18 or the like, which can be mounted on the back surface of the joint cover main body 12. 20, a pair of support pieces 21, 21 formed on the upper surface of the base plate 20 so as to protrude upward so that the lower end of the hanging rod 8 can be inserted into the center of the base plate 20; The pair of support pieces 21 are formed with pivot pin insertion holes 23 in which pivot pins 22 for pivotally supporting the lower ends of the suspension rods 8 are inserted. .
[0010]
The horizontal holding mechanism 17 has one end attached to a part near one end where the joint cover main body 12 rotates downward, and the other end attached to a part near the upper part of the hanging rod 8. A coil spring 24 for urging one end of the cover body 12 to rotate upward, and one end is attached to a portion near the other end where the joint cover body 12 rotates upward, and the other end is A stopper 25 attached to a portion near the upper portion of the suspension rod 8 and using a wire for preventing the joint cover main body 12 from rotating downward from a substantially horizontal state, and one end of the joint cover main body 12 On the side, the joint cover main body 12 is constituted by a stopper piece 26 which comes into contact with the mounting bracket 9 in a substantially horizontal state.
[0011]
In the ceiling joint cover 1 having the above structure, the joint portion 2 between the left and right ceiling frames 3a, 3a is covered by the joint cover body 12, and as shown in FIG. Only the members 15 and 16 can be seen.
[0012]
When the right and left buildings 3 and 3 swing in different left and right directions due to an earthquake or the like, and the joint portion 2 is widened, the joint cover main body 12 is kept substantially horizontal by the horizontal holding mechanism 17 as shown in FIG. Then, both ends of the support bars 7, 7 slide and move to absorb the swinging movement.
In this case, since the suspension rods 8, 8 are located substantially at the center of the joint portion 2, a gap is formed between both end portions of the joint cover main body 12 and the left and right ceiling frames 3a, 3a.
[0013]
When the joint portion 2 becomes narrow, the joint cover main body 12 resists the urging force of the coil spring 24 of the horizontal holding mechanism 17 by the inclined surfaces 13 and 14 of the left and right guide members 15 and 16 as shown in FIG. To rotate and absorb the swaying motion.
When the swinging motion stops, the joint cover main body 12 is stopped by the stopper 25 and the stopper piece 26 by the urging force of the coil spring 24 of the horizontal holding mechanism 17, and automatically returns to a substantially horizontal state to return to the original state. .
