Description

[Detailed description of the invention] Industrial field of application This invention is a soundproof cover for covering and soundproofing a machine that generates noise such as a press. This invention relates to an opening/closing device for a soundproof cover that opens and closes an opening part of a soundproof cover.

BACKGROUND ART Conventionally, this type of soundproof cover has an opening on the upright surface and an opening on the top surface following this, and a door that opens and closes the opening on the upright surface and opens and closes the opening on the top surface. is proposed. Normal mold replacement is usually done from the front using a forklift, but when replacing a particularly large mold or disassembling the machine, it is necessary to open and close the top. However, there is a drawback that if the top surface is also open, most of the noise will be transmitted into the factory, which is often the case when large materials are loaded and unloaded or trial shots are performed.

Problems to be Solved by the Invention This invention provides an opening/closing device for a soundproof cover in which the upright door can be opened and closed independently, and the top door can also be opened and closed at the same time as the upright door if necessary.

Means for Solving the Problem This invention is a soundproof cover that has an opening formed on an upright surface and an opening formed on the top surface following this opening, and has an upright door and a top door that open and close each opening. The opening/closing device is provided with an engagement device for mutually engaging and disengaging the upright door and the top door,
A soundproof cover characterized in that the upright door can be opened and closed independently by disengaging the engagement device, and the top door can be opened and closed simultaneously with the upright door when the engagement device is engaged. The present invention provides a switchgear for this purpose.

Embodiment In one embodiment of the invention shown in the figure, reference numeral 10 denotes a main body of the soundproof cover, which is formed with an open section 12 on the upright side and an open section 13 on the top side following the open section 12. Reference numeral 15 designates a pair of upright doors for opening and closing the open portion 12 of the upright surface, and has wheels 18 that roll along rails 17 provided on the floor surface 16. Reference numeral 20 denotes a trochanter rotatably attached to the main body 10, which contacts a groove member 21 attached to the upper part of the back side of the upright door 15 so as to extend in the horizontal direction, and guides the upright door 15 so that it does not fall down. It's summery. Reference numeral 22 denotes a sealing portion provided on the outer edge of the upright door as required. The upright door 15 is the main body 1
0, without using the wheels 18, or the wheels 18 may be configured to roll on a concrete surface.

Reference numeral 25 designates a pair of top doors for opening and closing the open portion 13 on the top surface, each of which has four rollers 26 on both sides of its rear end and rolls along guide rails 27 attached to the main body 10. It can be opened and closed without tilting. 28 is a cover that covers the rails and other parts. 30 is a trochanter provided on the lower surface of the front outside of the top door 25, and a guide rail 31 attached to the top surface of the main body 10 when opening and closing the top door.
It is designed to guide you along the way. Reference numeral 32 denotes a closing portion that closes the gap between the outer edge of the top door 25 and the main body 10 as necessary. This blockage is the main body 1
0 so as to protrude upward.

33 are an upright door 15 and a top door 2 that are adjacent to each other.
This is an engagement device for engaging and disengaging 5, and is constructed as described below. That is, 35 is a handle provided on the front surface of the upright door 15, and a lever 36 is integrally provided. Reference numeral 37 denotes an engaging member which extends vertically within the upright door 15 and is arranged to be able to be raised and lowered, and which is raised and lowered by the rotation of the lever 36. The handle 35 is held in the lowered position as shown by the chain line in FIG. It is designed so that it does not protrude from the upper end surface of the upright door 15.
In this state, the upright door 15 can be opened and closed independently of the top door 25. When the handle 35 is rotated to the position shown by the solid line, the upper end of the engagement member 37 protrudes upward and is inserted into and engaged with an engagement portion 38 consisting of a hole formed in the top door 25. 3
Reference numeral 9 denotes a stopper provided on the upright door 15 so as to be retractable by a spring in order to maintain this engaged state. In such a state, opening and closing the upright door 15 will open the top door 2.
5 can be opened and closed at the same time. 40 is a front inner edge of the top door 25 so that the top door 25 can be closed at the same time even if the engagement member 37 is lowered with the top door 25 opened together with the upright door 15. The engaging protrusion protrudes downward, and when the upright door 15 is closed, the inner edge of the upper end abuts and engages, thereby simultaneously closing the upper door 25, and forms part of the engaging device 33. are doing. Such an engaging protrusion is not formed on the top door 25 and the width of the engaging portion 38 is made slightly longer toward the outside so that the engaging member 37 can be easily inserted and engaged at an approximate position. Alternatively, the upper outer edge of the upright door 15 may be made to protrude upward to achieve the same effect.

This invention can also be applied to the case where one pair of upright doors 15 and one pair of top doors 25 are provided so that they can be opened and closed on both sides, but one each is provided so that they can be opened and closed only on one side. be.

Effects of the invention This invention has an upright door 15 and a top door 2 that can be engaged and disengaged by an engagement device 33 in a soundproof cover.
5, when frequently loading and unloading a large material or performing trial shots, the engagement device 33 can be disengaged and the upright door 15 can be opened and closed independently. The top door 25 prevents sound from being transmitted from the top to the outside, and when replacing a particularly large model or disassembling a machine, operate the upright door 15 in the engaged state of the engagement device 33 to open the top door. 2
5 can be opened and closed at the same time.
