Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a sliding door gate, and more particularly to a large sliding door gate having a wide opening.

Conventional technology As a large-sized sliding door, a long door is installed in the opening of the gate so that it can traverse freely, and a roller is provided at a position close to the opening of the gate to prevent the door from collapsing. It is known that two columns of the above are installed upright (for example, in Japanese Utility Model Laid-Open No. 59-40).
496 publication).

In this structure, the entire length of a door with wheels is the same as the opening of the gate, and a supporting arm is extended horizontally horizontally above the rear part of the door. Therefore, the door at the closed limit is prevented from falling down by the two gate-shaped columns holding the arm. The wheels at the rear of the door are door wheels that run on rails.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional technique, when the door is in the closed limit, the door is prevented from collapsing by supporting only the upper rear part through the gate-shaped column and the supporting arm. However, when the opening of the gate is wide and the total length of the door is long, the gate becomes weak against lateral load, which is extremely dangerous. Further, in order to cover this drawback, it is effective to restrain the lower rear portion of the door so that it cannot move laterally by using the rear wheel as a door wheel and running on the rail. Not only is the installation work troublesome, but if solid matter such as earth and sand or snow and ice accumulates on the rails, the door roller may not run smoothly, and the door may be opened and closed heavily or the door may become unopenable. It tends to happen.

Therefore, in view of the problems of the prior art, an object of the present invention is to make the door sufficiently long and to hold the door from both sides regardless of the opening degree of the door. Is to provide a sliding door that can support the door sufficiently strong against lateral load without providing a troublesome rail even if the opening of the gate is wide. .

The configuration of the present invention for achieving the above-mentioned object is to provide a door that is arranged transversely to the opening of the gate through front and rear wheels traveling on the ground, and a position immediately adjacent to the opening of the gate. Two gate-shaped columns with a pair of upper and lower rollers that hold the door from both sides, regardless of the opening of the door, and a door stop attached to the lower rear part of the door, The rear wheel is provided with an opening stopper with which the door stop collides at the opening limit of the door.
When the door is in the closed limit, the gist is that it is located between the gate columns.

Action According to the configuration of the invention, the door at the closed limit is
The rear part of the door is supported by two gate-shaped columns, and each gate-shaped column can hold the upper and lower portions of the door in a laterally immovable manner via a pair of upper and lower rollers. That is, the door at this time can be sufficiently strongly supported by the two gate-shaped columns. Further, at this time, since the rear wheel of the door is located between the gate-shaped columns, there is no possibility that a lateral load is applied, and it is not necessary to restrain the lateral movement via the rail.

Example Hereinafter, an example will be described with reference to the drawings.

The sliding door type gate is mainly composed of two doors 1 and 1 and two gate-shaped columns 10 and 10 provided for each door 1 (first
(Fig. 2, Fig. 2).

Each door 1 is configured by combining a frame body 2 and a large number of vertical bars 2a, 2a .... The door 1 is movably arranged in the opening L of the gate through wheels 3 provided near the front and rear ends of the lower surface of the frame body 2. The wheels 3 and 3 all travel on the ground G. Further, the door 1 is defined such that the opening direction side is rear and the closing direction side is front.

The two gate-shaped pillars 10 and 10 are erected on the ground G along the fence or fence F forming the opening L of the gate at a position close to the opening L of the gate with an appropriate distance D. There is. Each gate-shaped prop 10
Includes a pair of upper and lower rollers 11, 11 ... For sandwiching the upper and lower portions of the frame body 2 of the door 1 from both sides. (Fig. 4). The door 1 is sufficiently longer than 1/2 of the opening L of the gate (Fig. 1), and the rear portion of the door 1 is rearward of the rear gate-shaped column 10 when the door 1 is in the closed limit. Shall be projected up to. That is, the gate-shaped columns 10, 10 can hold the door 1 from both sides via the rollers 11, 11 ... Regardless of the opening degree of the door 1. Further, at this time, the rear wheel 3 is located between the gate columns 10 and 10.

A door stop 20 is attached downward to the lower rear portion of the frame body 2 of the door 1. Further, on the ground G, an opening stopper 30 with which the door stop 20 collides with the door 1 at the opening limit is installed.

The door stop 20 is configured by combining an L-shaped short piece 21 and a reinforcing rib 22 (Fig. 5). Also, open stopper
In the groove 30, a pillar 34 having a groove-shaped cross section is erected on the bottom plate 33, and a reinforcing rib 35 is formed between the pillar 34 and the bottom plate 33.
An elastic body 31 such as cushion rubber facing the door stop 20 is replaceably attached to the door via a bolt nut 32. The opening stopper 30 is fixed to the ground G via anchor bolts 36, 36.

On the side of the lower rear part of the frame 2 of the door 1, a closing stopper 40
Is attached (Fig. 2). However, the opening / closing stopper 40
Collides with the side surface of the rear gate-shaped column 10 at the closed end of the door 1. That is, the opening / closing stopper 40
Attach a reinforcing rib 42 to the L-shaped short piece 41 (Fig. 6),
For the L-shaped short piece 41, through the bolt nut 44,
An elastic body 43 opposed to is replaceably attached.
The closing stopper 40 is fixed to the frame body 2 via a bolt nut 45.

A lock fitting 50 is attached to the upper side surface of one of the two sets of the gate-shaped columns 10 and 10 on the front side near the opening L of the gate (Figs. 1 and 7).

The lock fitting 50 is formed by inserting the pin 52 into the groove-shaped member 55, and the pin 52 has such a length that it can reach the receiving plate 60 attached to the door 1. However, the pin 52 has a protrusion 52
The insertion hole of the pin 52 provided in the groove-shaped member 55 while providing the a and 52a is an upward key hole 53 through which the projecting pieces 52a and 52a pass on the flange 55a on the opposite side of the door 1 (eighth embodiment).
Figure). On the other hand, the receiving plate 60 is fixed to the vertical bars 2a, 2a of the door 1 at a position overlapping the lock fitting 50 at the open end of the door 1 (FIG. 3). The receiving plate 60 is provided with a pin hole 61 through which the pin 52 can be inserted (Fig. 7).

A so-called French drop 70 is attached to the front end of the door 1 (Fig. 1).

The door 1 of such a sliding door type gate, regardless of its open / closed state,
Two gate-shaped columns 10, which are erected at intervals D, are supported by being sandwiched from both sides by rollers 11, 11 ... Built in the columns 10. Therefore, the door 1 is restricted in its traveling direction, can go straight through a predetermined opening / closing path, and is not inadvertently tilted even by an abnormal lateral load such as wind pressure.

When opening the door 1, at the open limit,
20 collides with the release stopper 30. Therefore, the door 1 is
It can be reliably stopped at an appropriate position, and the pin 52 of the lock fitting 50 is inserted into the pin hole 61 of the receiving plate 60, whereby the open state can be reliably maintained (third part).
Figure). At this time, since the door stop 20 is positioned below the frame body 2, the opening stopper 30 does not have a large bending moment that is received by the door stop 20 and can be made extremely small. Further, the door 1 is fixed by removing and inserting the pin 52, and the pin 52 connects the protruding pieces 52a, 52a to the groove-shaped member 55.
It may be inserted and removed according to the key hole 53 of. Therefore,
The pin 52 can securely fix the door 1 without accidentally falling off (Fig. 7).

When closing the door 1, close the stopper at the closing limit.
The 40 collides with the rear gate column 10. That is, the door 1 is
Never overshoot. The closing stopper 40
Since it is located below the frame 2, it can be used in the event of a collision.
The bending moment received by is small, and it is not necessary to make the section modulus of the portal stanchions 10 particularly large. In addition, the French drop 70 of the door 1 fixes the door 1 in the closed limit and holds the door 1 securely in the closed state.

Other Embodiments The opening stopper 30 can be provided with a top plate 37 covering the elastic body 31 at the upper part (FIG. 9). Also, the door stop at this time
A protrusion 23 having an abutment surface approximately the same size as the elastic body 31 may be formed on the 20. The top plate 37 shields direct sunlight, and the elastic body 31
Reduces the speed of solidification and embrittlement due to natural deterioration of
31 lives can be extended.

Similarly, the closing stopper 40 can also be provided with a top plate 46 that covers the elastic body 43 at least at the upper portion (FIG. 10). In addition, an elastic body is provided on a side surface of the gate-shaped column 10 with which the elastic body 43 abuts.
You may form the protrusion 12 which has an abutting surface of substantially the same size as 43.
The top plate 46 can reduce the deterioration rate of the elastic body 43 in the same manner as the top plate 37.

In the above description, the doors 1 and 1 form a double-opening sliding door type gate, but the present invention is also applicable to a single-opening sliding door type gate that uses only one door 1. However, at this time, the closing stopper 40 can be omitted by abutting the front end of the door 1 against a gate post (not shown).

EFFECTS OF THE INVENTION As described above, according to the present invention, there are two gate-shaped stanchions each having a door that is arranged transversely through the opening of the gate via wheels and a pair of upper and lower rollers that are sandwiched from both sides. By combining and, the door can reliably restrain the upper and lower parts of the rear through the rollers of each gate-shaped strut regardless of the opening degree, so the door has a wide opening and is a long door. Even if there is, there is an excellent effect that it is not necessary to use any troublesome rail and the necessary and sufficient strength against lateral load can be easily realized.
