Description

[Detailed description of the invention] Industrial applications This invention relates to a soundproof covering rail.

Conventionally, large and noisy machines, such as high-speed presses, are further covered with soundproof covers during operation in factories. In order to easily allow machines and articles to enter and exit the soundproof cover, the door is usually a sliding door that is hung from a rail provided above, without providing a rail on the floor. Swinging doors that rotate around hinges require a large amount of space to open, so they are rarely put to practical use. In a door that is hung on a rail to open and close, the rail needs to protrude laterally from the main body of the soundproof cover in order to open as wide as possible.

Problems to be Solved by the Invention When the rail protrudes laterally from the main body of the soundproof cover, it becomes a hindrance to the movement of a vehicle such as a forklift. Therefore, there is a problem in that it is necessary to provide a barrier or other means to prevent vehicles from entering under the protruding portion of the rail, which requires space.

The present invention provides a rail for a soundproof cover door that solves these problems.

Means for Solving the Problems The present invention provides a system in which a rail of a predetermined height is arranged along the outer surface of the main body of a soundproof cover, and a door is suspended from the rail and moved. A fixed rail that hardly protrudes in the direction, and a fixed rail that is connected to at least one end of the fixed rail so that a predetermined length is always kept bent upward and automatically when moving the door outward. The present invention provides a rail for a soundproof cover door, characterized in that it includes a movable rail that is horizontal and projects outward from the main body so as to be able to support the door.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

An embodiment of the present invention shown in the figure, 1o is the main body of a box-shaped soundproof cover, which has a sound-absorbing structure made of sound-absorbing material, and the lower end is placed in contact with the floor surface or It is buried in Reference numeral 12 denotes two doors having a sound-absorbing structure that open and close one side of the main body of the soundproof cover, and are movable along a horizontally extending rail 15 provided on the outer upper part of the main body 10.

The rail 15 is constructed as described below. That is, reference numeral 16 is a fixed rail fixed to the main body 10 by a plurality of connecting members 17 so as not to protrude from both sides of the main body 10. The fixed rail 16 has an opening 18 along the center of the lower surface, and supports 20 are formed on both sides of the opening 18. Therefore, each pair of trochanters 22 supported by the bearing member 21 attached to the upper part of the door 12 is supported by the support part 20 and can be moved. 23 is fixed rail 1
A movable rail connected to both ends of the rail 6 so as to be rotatable and bendable, and in a horizontal state, an opening 18 and a support part 20 are formed following the fixed rail 16, and the outer end is closed. It is. The connecting portion of this movable rail 23 is as follows.

That is, 25 is the end of the fixed rail 23 and each support part 20
reinforcing plates each fixed to the lower surface of and extending outward; 26.
27 is a reinforcing member attached to the outer side of the end of the fixed rail 23 and the side facing the main body 10, and 28 and 29 are reinforcing members 26 connected to both sides of the movable rail, respectively.
, 27, and 30 is a screw that passes through the connecting plate 28 and is screwed into the reinforcing member 26.

Reference numeral 31 denotes a female screw member that penetrates through the connecting plate 29 and is fixed thereto, and faces the reinforcing member 27. A screw 32 having the same central axis as the screw 30 is inserted from inside the fixed rail 16 into the fixed rail and the reinforcing member. 27 and are screwed together. Therefore, the movable rail 23 can rotate around the central axis of the screw 30.32, and when it becomes horizontal, it contacts the reinforcing plate 25 and does not rotate any further downward, and when moving upward, the fixed rail 16 It touches the end of the body and stands almost upright as shown in FIG. 33 is a cylindrical body that surrounds the outside of the female screw member 31 and is fixed to the connecting plate 29 at one end so as to be integral with the connecting plate 29, and the other end extends inwardly through the wall 50 of the main body io; The mounting member 35 fixed to the cylindrical body 33 is a weight that is fixed to the mounting member so that the movable rail 23 always moves upward. Reference numeral 37 denotes a cylinder provided at a portion where the cylinder 33 penetrates the wall 50 of the main body 1O and fixed to the wall 50. The cylinder 37 is provided with a button so as to rotatably support the cylinder 33 via a pair of ball bearings 38. ing.

In the configuration as described above, the movable rail 23 is normally bent upward as shown in FIG.
3 and is pushed, the movable rail 23 rotates horizontally and projects laterally from the main body 10, as shown in FIG.

When the door 12 is moved again and the trochanter 22 is separated from the movable rail 23, the movable rail 23 is rotated upward by the weight 35.

In this invention, the reinforcing plate 25 may be fixed to the movable rail 23 without being fixed to the fixed rail 16.

Furthermore, in order to automatically rotate the movable rail 23 upward, the weight 35 may not be used and the movable rail 23 may be rotated by a helical spring. In addition, the movable rail 23
may be provided on only one of the fixed rails 16 instead of on both sides.

Effects of the Invention As described above, the present invention has a fixed rail 16 that extends upward at all times at the end of the fixed rail 16, which hardly protrudes outward from the main body 10 of the soundproof cover, and automatically becomes horizontal when the door 12 is opened wide. Since the movable rail 23 is provided that protrudes laterally from the main body 10, the door 12 can be opened sufficiently wide, and when the door 12 is not opened, the rail does not protrude for a long time to the side of the main body 10, so it does not interfere with the running of vehicles, etc. This has the effect that it will never become.
