Abstract

PURPOSE:To prevent the occurrence of vibration by a method in which a coupling inner frame is allowed to vertically move by an elevator provided for a floor face or a lower frame interlocking with an upper hanged door when the upper hanged door is closed or begins to open, and the lower end is supported when the upper hanged door is closed. CONSTITUTION:In a vibration preventor to be set on the lower part of a folding upper hanged door 1, a coupling inner frame 17 fitted in the groove 16 of a lower frame 15 and a coupler 18 on the lower end of the upper hanged door, which is to be fitted with or touched by the frame 17 are provided as a pair. The frame 17 is allowed to vertically move by an elevator 19. Since the frame 17 supports the lower end coupler of the door 1 closed, the occurrence of vibration can be effectively prevented even when the door 1 is set on places where great vibration occurs in train, vehicle, or ship, etc., and the reduction of noise and prevention of damage to upper hanging parts can thus be attained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a top-hung door suitable for use in a top-hung type sliding door or a folding door that is used in places with vibration such as trains, vehicles, and ships. It relates to a vibration prevention device.

[Conventional technology]

Conventionally, a top-hung door is equipped with a door iJi on a support shaft protruding from the upper end of the door body, and this is engaged with a guide rail formed on the upper frame etc. to suspend the door body upward, while the bottom part of the door body is suspended downward. It was inserted into the lower guide groove of a frame, etc. to about half the depth of the groove, and was swallowed.

[Invention or attempt to solve] [111 However, the lower structure of such a suspended door has a relatively large gap between the lower guide groove and the lower end of the door body swallowed by the lower guide groove in order to smoothly open and close the door body. When used statically, such as in buildings, this will only cause temporary problems such as during strong winds and rain. However, when used in areas subject to large vibrations, such as trains, vehicles, and ships, it may cause flapping in the front and rear directions. Moreover, since there is no support for the door body from below, vibrations in the vertical and horizontal direction of the door are also strong, causing noise and inconveniences such as the door body opening unexpectedly.

The present invention has been made in view of the problems of conventional above-hung doors.When the above-hung door is closed, the lower end is supported to prevent vibration, and when opened, this is released to enable smooth opening and closing. An object of the present invention is to provide a vibration-proof I-hi device for a top-hung door.

[Means for Solving the Problems] The present invention has been completed in accordance with the above object, and includes an engaging inner frame installed in a groove of a floor surface or a lower frame, and a mating inner frame that fits or pairs with each other. It is equipped with a retaining part at the lower end of the hanging door in contact with each other as a pair,
The engaging inner frame is characterized in that it can be freely moved downward by an elevating device provided on the floor surface or the lower frame that interlocks with the hanging door when the hanging door is completed closing or opening is started. The main purpose of this paper is to provide vibration prevention equipment for ceiling-hung doors.

[Function] As a result of the above, when the above-hung door vibration prevention device of the present invention completes the closing of the above-hung door, the engaging inner frame installed in the groove of the floor surface or the lower frame moves in conjunction with the above-hung door. Upper J4, J: Fits into or faces the engaging part at the lower end of the hanging door to support it. On the other hand, when opening of the hanging door is started, the engagement inner frame descends and releases the support of the lower end of the hanging door.

On the other hand, when starting to open the door body, pull the door body 4 horizontally toward the hanging base while keeping it extended (the extended length of the door body 4 in this example is the length of the lower frame 1).
The pressure of the engagement inner frame L on the receiving part 31 is released, and the engagement inner frame 1
7 is activated by the bias of a spring 34 stretched between the lower frame 15.

It should be noted that various interlocking mechanisms for the lifting and lowering device 19 of the engagement inner frame and the hanging door can of course be designed, and the hanging door l in this example is also provided with one kind of interlocking mechanism. That is, the first
The lock 35 in the figure is fixed to the hanging frame 14 of the door body, and can be freely locked to the inner frame 17 of the door body.
If the door body 4 is extended with the door locked and then pulled horizontally toward the door stop to close it, the inner frame 17 will be attached to the door body 4.
At the same time, it moves to the door stop side and rises along the L guide block 27. On the other hand, the door body 4 is closed in the locked state.
If you pull it horizontally towards the hanging base side while it is in the extended state, the inner frame 17
Along with this, it also returned to the hanging side and lined up along the guide flock 2°7.

It faces the lower end surface 42. Note that the engagement inner frame 17 in this example descends due to its own weight.

Incidentally, points common to each embodiment are denoted by the same numbers in the drawings, and some explanations are omitted.

Although not shown in the drawings, the above-hung door may be equipped with the present vibration prevention device in addition to the illustrated folding door or sliding door, for example, as an accordion curtain or the like.

In addition, the fitting/contact between the retaining inner frame and the engaging part at the lower end of the hanging door may be only fitting or only facing each other, and furthermore, the fitting/contact between the inner frame and the engaging part at the lower end of the hanging door may be limited to fitting or only to facing each other. In the case of a folding door that is folded, it is also possible to fit or abut the engaging inner frame only on the protruding side surface of the lower end of the hanging door.

On the other hand, the interlocking mechanism for the lifting and lowering device of the engagement inner frame and the lifting door is as follows:
In addition to the illustrated example, for example, a link may be pivotally attached between the engagement inner frame and the lower frame, and the engagement inner frame may be moved up and down by raising and lowering the link, or the left and right ends of the engagement inner frame may be suspended by wires. (In this case, as a means of interlocking with the hanging door, for example, a touch sensor or the like may be provided to control the drive motor.)
Furthermore, it is also possible to use hydraulic, pneumatic, etc. actuators.

The specific structure, shape, dimensions, material, number, arrangement, and relationship of the lifting door, engagement part, lifting installation, etc., as well as the means for interlocking the lifting device to the lifting door and the installation location of the lifting door, etc., vary. It goes without saying that the embodiments may be modified and are not limited to the above embodiments.

[Effects of the Invention] The vibration prevention device for a hanging door of the present invention has an engaging inner frame installed in a groove on a floor surface or a lower frame, and a lower end of a hanging door that fits or faces each other. The engaging inner frame is provided with a pair of engaging parts, and the engaging inner frame is moved by a lifting device provided on the floor surface or the lower frame that interlocks with the hanging door at the time of completion of closing or the start of opening of the hanging door.
Since it is movable up and down, the retaining inner frame supports the lower end retaining part of the closed top-hung door, so even when the top-hung door is installed in a location with large vibrations, such as on a train, vehicle, or ship. By effectively preventing the vibration, it is possible to reduce noise and prevent damage to the upper hanging parts.

Further, the holding inner frame of the vibration prevention device of the present invention is installed in the groove of the floor surface or the lower frame, and is interlocked with the floor surface or the lower frame when the suspended door is closed or begins to open. Since it can be moved up and down by the lifting device installed in the door, when opening the suspended door, the engaging inner frame can be lowered into the groove of the floor or the lower frame, and it will not become an obstruction to traffic. The appearance can also be made simple.
