Description

Description: TECHNICAL FIELD The present invention relates to a soundproof bracket for soundproofing by closing the upper and lower gaps of a movable partition wall.

[Conventional technology]

In this type of soundproof structure, for example, as shown in Japanese Utility Model Publication No. 61-23595, a long door is provided along the opening direction of the door at the lower end of the door (which has the same meaning as a movable partition wall. A sealing member (which has the same meaning as a soundproof bracket; the same applies below) is provided so that it can move up and down, and a protruding member is provided so that one end projects from the side edge of the door, and when the door is closed, the door frame or the adjacent door side There is known a structure in which the sealing member is moved by the retracting operation of the protruding member that abuts against the end.

Further, for example, as shown in Japanese Utility Model Publication No. 63-5190,
A horizontal rod is provided in the door body so as to be movable in the opening direction of the door, and a vertical rod is provided so that the vertical rod can be moved by the movement of the horizontal rod.
There is known a structure in which a long sealing member is attached to the lower end of a vertical rod and the sealing member is moved up and down by an external handle connected to the horizontal rod.

[Problems to be Solved by the Invention]

By the way, in the former one, the mounting structure is complicated, and since one end of the projecting member projects from the side end of the door when the door is opened, it is inferior in appearance and inconvenience cannot be avoided.
Moreover, the danger to the human body due to the protrusion cannot be denied.

Also, in the latter case, since it is operated by a handle or handle as a general door element, it is possible to eliminate a feeling of strangeness in appearance, but since the operation mechanism other than the handle is provided inside the door body, the movable partition wall is provided. However, the manufacturing cost was increased because it was limited to the combined structure.

Further, even if it is applied to a type in which the upper and lower sealing members are simultaneously operated by one handle, it is inevitable that the structure becomes large and complicated. At the same time, it was extremely difficult to add to the existing door, so it lacked usability.

Therefore, the present invention can be easily attached to the movable partition wall, and can be easily applied to the simultaneous vertical operation type by one operation member, and is highly usable and does not deteriorate the appearance. The purpose is to provide a soundproof bracket for a movable partition wall.

[Means for Solving the Problems]

In order to achieve the above object, the present invention has a structure in which a bracket mounted on at least one of the upper and lower end surfaces of a movable partition wall can be operated from one end side of the bracket, thereby simplifying the structure for mounting the movable partition wall. The feature is that the fixed bracket with a U-shaped cross section is fixed to at least one of the upper and lower end faces with the opening side facing outward in the vertical direction, and it is slidably attached to the fixed bracket in the vertical direction. And a moving bracket that is urged by a spring member so as to always project outward in the vertical direction.A link mechanism that can expand and contract in the vertical direction is provided between the moving bracket and the fixed bracket by the movable bracket and the fixed bracket. The movable bracket is covered and attached, and the moving bracket is connected to the link mechanism with its approximate center. The configuration is that the operating link elongated end of a vertically rotatably one end is pivotally supported operation terminal is located in the longitudinal end of the bracket is provided.

[Work]

According to the present invention, for example, an operation case provided with an operation handle is embedded and fixed at one end portion on the left and right sides of the movable partition wall, and an operation rod is provided along the left and right end surfaces of the movable partition wall. It is possible to have a mounting structure that connects the operation end of the operation link. This simplifies the structure and facilitates attachment to the movable partition wall. By connecting the upper and lower operation rods to the operation case, the upper and lower moving brackets can be simultaneously operated by one operation member.

When the operation handle is rotated from the soundproof state in which the gap is closed by the moving bracket, the operation link is rotated in the vertical direction and the link mechanism contracts. At the same time, the moving bracket is moved to the fixed bracket side against the urging force of the spring member, whereby the soundproof state is released. Since the link mechanism is connected to the approximate center of the moving bracket,
The movement of the movement bracket is performed without displacement. When the operation handle is rotated from the soundproofing-released state, the moving bracket projects outward due to the urging force of the spring member, and the gap is closed to bring the soundproofing state.

〔Example〕

 1 to 7 show an embodiment of the present invention.

An example of application to a foldable movable partition wall is shown. As shown in FIG. 1, an upper rail 2 and a lower rail 4 are provided.
Movable partition walls 6 and 8 are connected to each other with a hinge 10 so as to be foldable. The movable partition walls 6 and 8 are hung at their upper ends by upper runners 12 and 12, and are supported at their lower ends by lower runners 14 and 14 located on the same axis as the upper runner 12.

A soundproof bracket 20 for closing the gap G between the movable partition walls 6 and 8 is provided on the upper and lower end surfaces of the movable partition walls 6 and 8, respectively. Each soundproof bracket 20 is capable of simultaneously performing soundproofing and its canceling operation at the same time through an operation rod 24 by an operation case 22 embedded and fixed in one of the left and right ends of each movable partition wall 6, 8. The operation by the operation case 22 is performed by rotating an operation handle 25 exposed to the outside of both surfaces of the movable partition wall 6.

As shown in FIGS. 2 to 5, each soundproof bracket 20 has a long fixed bracket 26 having a U-shaped cross section which is fixed to the upper and lower end surfaces of the movable partition walls 6 and 8 with the opening side facing upward and downward. And a long moving bracket 28, which is provided inside the fixed bracket 26 and has a U-shaped cross section. A support shaft 30 is provided upright on the bottom surface of the fixed bracket 26 at intervals in the longitudinal direction, and an insertion hole 32 for inserting the support shaft 30 is formed in the bottom surface of the moving bracket 28 correspondingly. ing. Spindle prior to mounting the moving bracket 28
A spring member 34 is fitted in 30 so that the moving bracket 28 is urged outward. Further, the moving bracket 28 is detachably stopped after being mounted on the support shaft 30.

The fixed bracket 26 and the movable bracket 28 are the link mechanism 36.
Are connected by. The link mechanism 36 is a short link 38.
And a long operation link 40 as an operation member for contracting the link mechanism 36, and the outer surface of the mechanism is covered with a fixed bracket 26 and a movable bracket 28. One end of the short link 38 is rotatably supported by a pin 44 on a mounting piece 42 fixed to the center of the bottom surface of the moving bracket 28.
The other end is rotatably supported by a pin 48 on one end side of a long attachment piece 46 fixed to the bottom surface of the fixing bracket 26. On the other hand, one end of the operation link 40 is rotatably supported by the pins 50 and 50 on the other end side of the attachment piece 46 at a position substantially equal to the attachment end of the link 38 to the moving bracket 28, and the fixed bracket 26 of the link 38 is fixed. A link 52 is connected to the link 38 by a pin 52 in a crossing state at a position closer to the appropriate size moving bracket 28 from the mounting end thereof. Connection hole that can be formed in either one
The connecting hole of the moving bracket 28 side of the link 38a and the link 38 is formed in a long hole shape to absorb the displacement at the time of contraction / expansion. The other end of the operation link 40 extends to one end in the longitudinal direction of the bracket, and an insertion hole 40a through which the support shaft 30 is inserted is formed on the way. An operation end 40b, which is a free end of the operation link 40, is formed with an engagement recess 40c into which the operation rod 24 is engaged and an abutment surface 40d with which the operation rod 24 abuts.

FIGS. 1 and 2 show the soundproof position CL in which the movable partition walls 6 and 8 are closed and the moving bracket 28 projects, and when the movable partition walls 6 and 8 are opened, as shown in FIG. In addition, the movement bracket 28 is retracted by the rotation of the operation handle 25, and the soundproof release position OP is obtained.

More specifically, when an operation force is applied in the arrow N direction via the operation rod 24 to the operation end 40b of the operation link 40 from the soundproof position CL where the moving bracket 28 is projected by the urging force of the spring member 34, the operation is performed. The link 40 is rotated around the pin 50. With the rotation of the operation link 40, the short link 38 is rotated around the pin 48, whereby the link mechanism is rotated.
When 36 is contracted and the moving bracket 28 is retracted into the fixed bracket 26, the soundproof release position OP
Is obtained. Since the short link 38 is connected to the substantial center of the moving bracket 28, the moving bracket 28 can be uniformly retracted and retracted over the entire movement. Link 38
The connection position between the operation link 40 and the operation link 40 (pin 52) and the length between the pin 50 and the pin 52 are the operation case based on the stroke amount of the operation rod 24, the elasticity of the spring member 34, and the rotation moment of the operation link 40. It is decided as appropriate in consideration of the operability of 22. When the operating force is removed by moving the operating rod 24 in the direction of the arrow M from the soundproofing release position OP, the moving bracket 28 is projected outward by the urging force of the spring member 34, and the upper end thereof is the stepped portion of the rails 2, 4. The gap G is closed in an airtight state by coming into contact with 2a and 4a. Since the moving bracket 28 has a U-shaped cross section, even if the position dimension of the movable partition wall 6 in the front-back direction is deviated, one of the front and rear edges of the U-shaped is in contact with the rail, so that airtightness can be obtained.

Above and below the end of the fixed bracket 26 on the side opposite to the operating side,
Mounting portions 54, 54 for mounting the upper runner 12 and the lower runner 14 from the outside are formed, respectively. The upper runner 12 is composed of, for example, a wheel-equipped runner main body 56 having a screw shaft 56a on the lower surface, and a runner support portion 58 screwed into and integrated with the screw shaft 56a. The runner support portion 58 is formed with a set screw portion 60 for obtaining fixation after mounting. The set screw portion 60 can be composed of a set screw 62 and a screw insertion hole 64 formed in the lower portion of the runner support portion 58 in the longitudinal direction.

The mounting portion 54 can be composed of, for example, a mounting portion main body 66 fixed to an end portion of the fixed bracket 26, and a screw portion 68 screwed to the set screw portion 60. A stopper piece 70 for positioning the upper runner 12 is continuously provided at the depth end of the mounting portion main body 66. The mounting portion main body 66 preferably has a shape capable of accommodating the runner support portion 58 without rattling. For example, the mounting portion main body 66 has a groove width equivalent to that of the narrow width portion 58a and a wide width corresponding to the runner support portion 58 having a convex cross section. The portion 58b can be formed in a substantially C-shaped channel material having a void portion having a size capable of closely accommodating. After mounting, the runner supporting member 58 is prevented from coming off in the height direction by the projecting edge 66a of the mounting portion main body 66. As the screw portion 68, for example, a nut screwed with the set screw 62 can be used, and in this case, the stopper piece 70 may be fixed by forming a through hole 70a through which the set screw 62 is inserted. On the other hand, at the corresponding position of the moving bracket 28,
The notch 72 is formed with a width slightly larger than the narrow width portion 58a of the 58, and this allows the mounting movement of the upper runner 12 to be permitted. Therefore, the runner support portion 58 is slidably mounted on the mounting portion main body 66, and the set screw 62 is screwed into the screw portion 68, whereby the upper runner 12 or the lower runner 14 can be easily attached and detached from the outside of the fixing bracket 26. .
In addition, the notch 72 prevents the upper runner 12 or the lower runner 14 from hindering the movement of the moving bracket 28. The mounting portion main body 66 is the runner support portion 58.
Can be shaped so as to be fitted from the upper surface side of the fixed bracket 26, and the screw portion 68 can be formed on the lower surface side of the fixed bracket 26.

A contact end 84a that contacts the contact surface 40d of the operation link 40 is formed on the inner side of the adjusting screw 84, and an operation groove 84b for adjusting the screw-in amount with a screwdriver or the like is formed on the outer side. There is. By rotating the adjusting screw 84, the contact position of the operation rod 24 with respect to the operation link 40 can be finely adjusted steplessly. That is, the soundproof position of the moving bracket 28
Fine adjustment of CL and soundproof release position OP can be performed. In the lower connection portion 80, a plurality of engagement recesses 86 corresponding to the set screws for connecting to the operation case 22 are formed at intervals in the vertical direction. The connection with the operation case 22 is one engagement recess 86.
However, if a position shift occurs during mounting on the movable partition wall 6, coarse adjustment of the position shift can be performed by selecting the connectable recess 86.
The combination of the fine adjustment of the upper connecting portion 78 and the coarse adjustment of the lower connecting portion 80 can surely perform the positional deviation at the time of mounting and the positional adjustment of the moving bracket 28. In addition, fixed bracket
A through hole 26a for inserting the operation rod 24 is formed on the bottom surface of the operation side end of 26, while the moving bracket 28
