Description

[Technical Field]

[0001] The present invention relates to a joint cover support device that supports a joint cover that closes a joint between wall surfaces of left and right frames provided with a joint therebetween. [Background technology]

[0002] A known example of a conventional wall joint device is a wall joint cover device comprising: "at least two or more telescopic link mechanisms with three central pivots in the center, both ends of which are pivotally supported on the outer wall surfaces of the left and right buildings on the side of the joint, and which are provided via the joint; U-shaped cover plates that are open on the left and right building sides and are pivoted to the central pivots on both sides of these telescopic link mechanisms with pivot pins fixed to the center of the inner plate; end cover plates that are pivoted to the pivots on both ends of the telescopic link mechanisms and have their tips inserted into the interior so as to slide so as to come into contact with the outer plates of the cover plates; and a central cover plate whose both ends, pivoted to the central pivots in the center of the telescopic link mechanisms, overlap with the outer plates of the cover plates and can slide" (Patent Document 1).

[0003] However, in such wall joint devices, even if multiple expansion link mechanisms are installed in the vertical direction to prevent deflection of the cover plate and mounting members, if the horizontal dimension of the joint portion is also large, an expansion link mechanism with multiple link portions has the disadvantage that the area near the center will deflect and displace downward.

[0004] Furthermore, since each of the multiple pivotal support parts is subject to bending, it is difficult to prevent bending in the front-to-rear direction due to strong winds, etc., even if multiple expansion and contraction link mechanisms are provided in the vertical direction.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-1111 Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above-mentioned conventional drawbacks, the present invention aims to provide a joint cover support device in which the central portion of an expandable link mechanism having multiple link portions does not easily bend or deform due to strong winds, etc., and which can absorb shaking caused by earthquakes, etc.

[0007] The above and other objects and novel features of the present invention will become more fully apparent from the following description read in conjunction with the accompanying drawings. However, the drawings are for illustrative purposes only and do not limit the technical scope of the present invention. [Means for solving the problem]

[0008] In order to achieve the above object, the joint cover support device according to claim 1 of the present invention is A joint cover support device used in a joint cover device that closes a joint between one frame and another frame, comprising: an expandable link mechanism having a plurality of central pivot portions for long mounting members that are provided at a required interval in the vertical direction at the joint and do not displace in the vertical direction; and mounting members that are arranged at a predetermined interval in the horizontal direction, are pivoted to the central pivot portions, and can mount a plurality of joint covers; the expandable link mechanism comprises a first link mechanism and a second link mechanism, one end of which is attached to the one frame and the other end of which is attached to the other frame; and these first and second link mechanisms are formed to be approximately the same shape; The first link mechanism and the second link mechanism are in a substantially abutting state. They are characterized by being positioned so as to overlap in the front-to-rear direction. The telescopic link mechanism of the joint cover support device according to claim 2 is characterized in that it is formed so as to have a substantially hexagonal or substantially quadrangular shape as a whole when viewed from the front.

[0009] Here, "the first and second link mechanisms are positioned so as to overlap" refers to a position in which the first and second link mechanisms are in contact with each other, or a position in which there is a slight gap between the first and second link mechanisms. [Effects of the Invention]

[0010] As is clear from the above description, the present invention provides the following effects. (1) In each invention described in claim 1, the vicinity of the center of the telescopic link mechanism having a plurality of link parts does not easily bend or deform due to strong winds, etc. In addition, since a second link mechanism is provided in the embodiment, the link mechanisms are arranged so as to overlap two or more times in the front-rear direction in a plan view, which can significantly improve the strength of the telescopic link mechanism. (2) The invention described in claim 2 also provides the same effect as (1) above, and because the entire telescopic link mechanism is formed to have a substantially hexagonal or substantially square shape when viewed from the front, it is possible to prevent the telescopic link mechanism from extending vertically if the joints become narrower due to an earthquake. Therefore, it is not necessary to widen the vertical spacing between the telescopic link mechanisms, and multiple telescopic link mechanisms can be installed. [Brief explanation of the drawings]

[Figure 9] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this specification, directions are referred to as left and right, top (top of the drawing) and bottom (bottom of the drawing) directions based on Fig. 4. Directions are referred to as front (bottom of the drawing) and rear (top of the drawing) directions based on Fig. 5.

[0013] In addition, in this invention, the term "structure" refers to a structure such as a building, road, slab, elevator shaft, etc., on which a joint plate can be installed, and the term "entrance" refers not only to an entrance with a door or a gate, but also to a passageway through which people, vehicles, etc. can pass.

[0014] In a first embodiment of the present invention shown in Figures 1 to 7, reference numeral 1 denotes a joint cover support device that supports a joint cover device X (e.g., Figure 5) that closes a joint 2 between one skeleton 3 and another skeleton 4. The joint cover support device 1 is a concept that includes the joint cover device X.

[0015] In Figure 1, 1 is a joint cover support device, 13 is a pair of left and right hinge members, 12 is a pair of left and right link mechanism mounting members, 9 is a first link mechanism located on the front side (joint cover side), 10 is a second link mechanism located on the rear side corresponding to the opposite side from the joint cover side, 8 is a long mounting part that is vertically long, such as a rod or rail-like member, 6 is an expandable link mechanism having a plurality of central pivot parts 5 to be mounted when viewed from the long mounting part 8, and 7 is a plurality of joint covers. The joint cover device X or joint cover support device 1 that closes the joint 2 between the left and right frames is made up of a combination of the above components.

[0016] The joint cover support device 1 of the present invention is composed of an expandable link mechanism 6 which is provided in plural at the joints 7 of both bodies 3, 4 at a required interval in the vertical direction and has a plurality of central pivot parts 5 for long mounting members 8 which do not displace in the vertical direction, and the mounting members 8 which are arranged at a predetermined interval in the horizontal direction and are each pivoted to the central pivot parts 5 and can mount a plurality of joint covers 7, and the expandable link mechanism 6 is composed of a first link mechanism 9 and a second link mechanism 10 which have one end attached to one body 3 and the other end attached to the other body 4, and these first and second link mechanisms 9, 10 are formed in approximately the same shape and are positioned so as to overlap in the front-to-back direction.

[0017] As shown in Figure 1, the joint cover support device 1 is composed of a plurality of telescopic link mechanisms 6 each having one end attached to one body 3 and the other end attached to the other body 4, and each having a plurality of central pivot parts 5 that are arranged in the vertical direction in the joint section 2 and do not displace in position in the vertical direction, and a plurality of mounting members 8 that are each pivoted to the central pivot parts 5 and can be used to attach joint covers 7.

[0018] As shown in Figures 2 and 3, the telescopic link mechanism 6 is composed of a first link mechanism 9 having one end attached to the one body 3 and the other end attached to the other body 4, and one or more second link mechanisms 10 having one end attached to the one body 3 and the other end attached to the other body 4, and arranged so as to approximately abut the front or back of the first link mechanism 9.

[0019] The telescopic link mechanism 6 may be approximately square in shape as a whole when viewed from the front, but is preferably formed to be approximately hexagonal or approximately square. In this embodiment, the link materials 11 are combined so that the shape is approximately hexagonal in front view, as if the upper and lower portions of a normal diamond-shaped link mechanism had been cut approximately horizontally.

[0020] As mentioned above, the first link mechanism 9 is formed by combining bar-shaped link materials 11, such as solid or pipe-shaped ones, in a pivoted state, crossing them in the front-to-back direction (the link materials 11 are staggered) so that they form an approximately hexagonal shape when viewed from the front, and the pivot parts attached to the left and right bodies 3, 4 and the pivot part positioned approximately horizontally to these pivot parts form the central pivot part 9a.

[0021] The second link mechanism 10 is formed by combining link materials 11 in a staggered manner so as to have substantially the same shape as the first link mechanism 9, and is provided so as to substantially abut against the first link mechanism. Note that providing the second link mechanism 10 so as to substantially abut against the front or back surface of the first link mechanism 9 does not mean that the link materials 11 are provided so as to be in close contact with each other, but rather that the second link mechanism 10 as a whole is provided so as to be overlapped so as to substantially abut against the front or back surface of the first link mechanism 9.

[0022] In other words, four link materials 11 are arranged alternately in the front-to-back direction and pivotally supported, and when viewed in a plane, the four link materials 11 are stacked without any gaps, and this state is achieved by providing the second link mechanism 10 so that it is in approximate contact with the front or back surface of the first link mechanism 9.

[0023] The central pivot portion 5 of the telescopic link mechanism 6 is formed by arranging the central pivot portion of the first link mechanism 9 and the central pivot portion of the second link mechanism 10 so that they are coaxial.

[0024] In this embodiment, the second link mechanism 10 is formed by two link members 11 crossing each other in a staggered manner and pivoting, as in a normal link mechanism, but it may also be formed by four or more link members 11 crossing each other in a staggered manner and pivoting (a double or more than double link mechanism).

[0025] By configuring the telescopic link mechanism 6 in this manner, with the first link mechanism 9 and the second link mechanism 10 in abutting contact, the strength and rigidity of the telescopic link mechanism 6 are significantly improved, and it can support joint covers, etc. without deformation or damage even when exposed to strong winds.

[0026] In this embodiment, the pivotal support portions at the left and right ends of the first link mechanism 9 and the second link mechanism 10 are pivotally supported together on a link mechanism mounting member 12 that is substantially in the shape of a channel steel. The left and right bodies are then attached to this link mechanism mounting member 12 via hinge members 13. In other words, the telescopic link mechanism 6 is attached to the left and right bodies 3, 4 via this link mechanism mounting member 12 and hinge members 13.

[0027] In this embodiment, the mounting member 8 is a bar-shaped member such as a solid or pipe-shaped member, and is pivotally supported on the central pivot part 5 of the telescopic link mechanism 6. Note that the mounting member 8 may also be configured with a substantially channel steel-shaped rail member pivotally supported on the central pivot part 5 of the telescopic link mechanism 6, and a mounting member main body fixed to this rail member.

[0028] In use, the joint cover 7 is fixed to the mounting member 8 with screws or the like. Any known joint cover can be used as the joint cover 7, and one example is one in which multiple joint covers 7 that are roughly crank-shaped in plan view are attached to the mounting member 8 so as to close the joint portion 2 without leaving any gaps.

[0029] The joint cover device X of the present invention using such a joint cover support device 1 is composed of the joint cover support device 1 of the present invention, which has one end attached to one of the frames and the other end attached to the other frame, and a joint cover 7 attached to the mounting member 8 of the joint cover support device 1 and which covers the joint portion 2, as shown in Figures 4 and 5.

[0030] When an earthquake causes the left and right frames 3 and 4 to shake so that the joint section 2 narrows, as shown in Figure 6, the expansion link mechanism 6 contracts in the left and right directions and displaces so that the overlap width of adjacent joint covers 7 increases, absorbing the shaking caused by the earthquake.

[0031] When an earthquake causes the left and right bodies 3, 4 to shake so that the joint section 2 widens, the telescopic link mechanism 6 extends left and right as shown in Figure 7, and displaces so that the overlap width of adjacent joint covers 7 becomes smaller, absorbing the shaking caused by the earthquake.

[0032] [Different modes for carrying out the invention] Next, different embodiments for carrying out the present invention will be described with reference to Figures 8 and 9. In describing these different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention will be designated by the same reference numerals, and redundant description will be omitted.

[0033] The second form for implementing the present invention shown in Figures 8 and 9 differs from the first form for implementing the present invention mainly in that it uses an expandable link mechanism 6A that is formed so that it has an overall approximately rectangular shape when viewed from the front, and even with such a joint cover support device 1A, the same effects as those of the first form for implementing the present invention can be obtained.

[0034] The first and second link mechanisms 9A, 10A constituting the telescopic link mechanism 6A of this embodiment have link materials 11 near the left and right ends that protrude towards the left and right body sides, and these protruding ends abut against the wall surfaces of the left and right body sides or the link mechanism mounting members 12, and when the telescopic link mechanism 6 extends or contracts in the left and right direction, the protruding ends are configured to slide up and down on the wall surfaces of the left and right body sides or the link mechanism mounting members 12.

[0035] In the embodiment of the present invention, the telescopic link mechanism is attached to the left and right frames via hinge members and link mechanism mounting members, but it is not necessary to use hinge members. Also, a spacer may be further used to attach the joint cover to at least one of the frames. By attaching the joint cover via a spacer in this way, it is possible to ensure a sufficient range of sway caused by an earthquake even when the joint cover is roughly flush with the front wall surface of the frame.
