Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a gate for snowy areas that is suitable for snowy areas.

[Conventional technical field]

Depending on the structure of the gate, there are known sliding door types, hinged door types, and sliding door types with a single door. However, in snowy regions, sliding gates become difficult to use due to snow accumulation and freezing on the rails laid on the ground, and with hinged door methods, the rotating hinges may freeze, and the snow removal area of the area where the hinged door F frame rotates is limited. Due to the large size, there was no gate suitable for snowy areas, so it was not used during the winter and became careless.

[Technical means that solved the problem]

In order to solve the above-mentioned problems, this invention has a sliding door body slidably supported in a semi-closed hollow case, a boss rod is provided on the bottom of the lower frame of the hollow case, and a support shaft is attached to the boss rod. A lever is provided at the front of this support shaft so that it can freely rotate toward the drawer side of the sliding door body, and a link is fixed to the rear end.A connecting member is connected to the link, and a bracket is attached to the connecting member. On the other hand, a stopper is provided on the sliding door body at a position where the bracket comes into contact when the bracket moves, and when the lever is rotated, the stopper provided on the sliding door body is brought into contact and interlocked with the bracket through the connecting member and the bracket. In particular, it is an object of the present invention to provide a gate for a snowy region, which is characterized in that it is provided with a popping device for pulling out a sliding door body in a hollow case, and that the lower part of the sliding door body that pops out has an appropriate gap from the ground.

〔Example〕

Figure 1 shows one embodiment of the present invention, in which a and a' are sliding door bodies, b and b' are hollow cases, and c is a pop-out device that pulls out the sliding door body in hollow case b. ing. In this embodiment, the hollow case b is attached to a block fence, and the hollow case b consists of several pillars 7, an upper frame 1, a lower frame 2, a cover body 5 surrounding them, and the like. Reference numeral 6 denotes a brush body which is implanted so as to touch the inlet of the hollow case b from the left and right sides. The sliding door bodies a and a' have an upper frame 8 and a lower frame 9, and when they are mutually closed, they are automatically locked by a locking device as shown in FIG. The relationship between the sliding door body a and the pop-out device c will be explained with reference to FIGS. 1 and 3. Stopper 19 at the rear of the lower frame of sliding door body a
to protrude. A pop-out device c is attached to the bottom surface of the hollow case b frame 2.

The pop-out device c includes a boss rod 3 provided on the bottom of the lower frame 2 and a support shaft 2 provided through the boss rod 3.
3 and a rotatable lever 14 protruding from the front part of the support shaft 23. On the other hand, 15 links are fixed to the rear end side of the support shaft 23, a connecting member 16 is connected to the link 15, and a bracket 17 is further fixed to the connecting member 16. The rear end of the connecting member 16 is engaged with and slidably supported by the guide rod 18.

The bracket 17 described above is configured at a position where it comes into contact with the stopper 19 of the sliding door body a when the connecting member 16 slides forward.

Therefore, when the lever 14 protruding from the hollow case b is lightly stepped downward with a foot, the support shaft 23 rotates forward about the boss rod 3, and at this time, the link 1
5 rotates forward at the same time. When the connecting member 16 connected to the link 15 moves forward, the bracket 17 comes into contact with the stopper 19 on the side of the sliding door body a, causing the sliding door body a to pop out.

Reference numeral 20 indicates a backing plate provided on the lower frame 2 side of the hollow case b, and after the sliding door body a pops out, the stopper 19 provided on the sliding door body a comes into contact with this backing plate 20. This is to lock the protruding position. The elastic body 24 in FIG. 3 is a body that keeps the link 15 in contact with the link 15 at all times, and returns it to its original position when the depressing action of the lever 14 is released. As shown in FIG. 4, the fixing position of the backing plate 20 can be adjusted using bolts and nuts, and 13 is a cutout hole provided in the lower frame 2 to prevent snow or dirt from falling when it gets inside. Because it is removed, it does not accumulate inside. Reference numeral 12 denotes a support roller that supports the sliding door body a by rolling.

FIG. 2 is an explanatory diagram showing how the upper frame 1 of the hollow case b and the sliding door body a are slidably supported. The upper frame 1 is made of channel materials symmetrically pasted together, and a pair of rollers 10 are engaged with each other, and the rear part of the upper frame 8 of the sliding door body a is adjusted up and down by a fixing bolt 22 hanging between the rollers 10. Fix freely.
A pair of horizontal rollers 11 are provided in front of the upper frame 1 in the horizontal direction, and are used to clamp and guide the upper frame of the sliding door body a. A scraper 21 serves to remove snow from the upper frame surface when the sliding door body a is pulled into the hollow case b.

Figure 5 shows another example in which a single sliding door is used due to the position of the fence and entrance of the residential area, and Figure 6 shows an example in which the sliding door bodies a and a' have a length of approximately 2:1. It is something that

[Action/Effect]

With the above structure, the sliding door body is smoothly centered within the hollow case and supported in an appropriate posture even in snowy areas. In particular, even when the snow is piled up on the sliding door body, it passes through the scraper and brush body, so no snow is brought into the hollow case, and if necessary, the sliding door body can be removed by simply rotating the lever lightly using the pop-out device. It can be pulled out.

Further, according to the present invention, if it is used as a management door of a livestock barn or the like installed outdoors in a snowy area, the troublesome work of opening and closing the door outside of the snow will be eliminated, and the practical benefits will be great.
