Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a rail attachment device, and more particularly to a rail attachment device for a door device installed in a freely openable/closable manner at the gable entrance of a greenhouse.

<Conventional technology> Conventionally, so-called vinyl houses, from large steel-framed houses to pipe houses, have vinyl sheets spread over the roof, walls, and gables, with an entrance especially provided on the gable or wall side for workers to enter and exit. . For this entrance, a rectangular frame is formed with a cross-sectional groove-shaped support frame, a vinyl sheet is stretched between these support frames to form a door, and this door is attached with hinges etc. so that it can be opened and closed freely. It is normal that this is done.

However, when a hinged door like the one described above is installed at the entrance, it is necessary to widen the opening each time a worker enters or exits, and due to the design, it is inevitable that there will be a small gap between the entrance frame and the door frame. There was a risk that when the door was opened, outside air would flow into the house through these gaps, lowering the room temperature. In particular, when a door is opened and closed using a hinge or the like, there is a problem in that the door opening is large and the closing operation is slow, resulting in a large amount of cold air entering the door and a lack of airtightness.

For this reason, a slidable door device has been developed for use in vinyl greenhouses, which is easy to open and close and is fairly airtight, as shown in, for example, Japanese Utility Model Application Publication No. 171968/1983.

<Problems to be solved by the invention> This door device has an upper rail made of a C-shaped rope that opens toward the room and a lower guide made of a C-shaped rope that opens upward. The roller is rotatably fitted to the upper rail, and the lower part of the door is slidably inserted into the lower guide.

However, in this door device, the rollers are fitted into the upper rail from the indoor side, and since the lower rail is a C-shaped rope that opens upward, the opening is in the center, so the door is inevitably placed on the indoor side. As a result, a space is formed between the lower surface of the upper rail, the upper surface of the lower guide, and the outer surface of the door, resulting in the problem that outside air enters the greenhouse through this space.

For this reason, the applicant has developed a door device for greenhouses, etc. that increases airtightness and minimizes the intrusion of outside air by making the space partitioned by the upper rail, lower guide, and door extremely small. (Utility Model Publication No. 60-26473).

However, the lower guide rail of this door device is formed in an inverted U-shape and is only held on the ground with a pin, so the height position of the lower guide rail cannot be adjusted freely and the installation and removal work is difficult. This is cumbersome, and there are problems in that the lower guide rail and pins become stuck during long-term use, and the lateral alignment of the lower guide rail becomes inaccurate.

Therefore, the purpose of the present invention is to provide a door that allows the height and lateral positioning of the rail to be freely and accurately performed, is easy to install and remove, prevents the rail from being buried underground, and maintains airtightness. An object of the present invention is to provide a mounting device for a rail in a device.

<Means for solving the problem> In order to achieve the above purpose, the structure of the present invention is as follows.
It consists of a rail holding part and a fixing member for the rail holding part, and the rail holding part is characterized by consisting of a bracket and one or more locking parts that stand up on the bracket along the longitudinal direction. It is.

<Function> The guide rail is held by simply fitting the inverted U-shaped guide rail into the locking portion.

<Example> Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in Figures 2 and 3, a large number of semicircular pipes are installed in a row on the ground surface, and a number of groove-shaped support frames with cross sections are installed in the direction that crosses the pipes. By holding the vinyl sheet in the dovetail groove through elastic locking lines, the vinyl sheet is spread on the roof and wall sides of the house. In addition, a large number of pipes 1 are vertically erected on the gable side of the greenhouse, and a groove-shaped support frame 3 with a cross section is connected to the pipe 1, and a continuous trapezoidal or wavy shape is formed in the dovetail groove of the support frame 3. The vinyl sheet is held through the elastic locking lines, and the vinyl sheet is spread over the entire gable side.

An entrance 4 is provided, for example, in the center of the gable side, and a door 5 is provided in the entrance 4 so as to be slidable.

That is, at the inlet 4, the joint 2 is connected to the pipe 1.
The upper rail 7 is connected horizontally via the
This rail 7 extends toward the entrance 4 and constitutes an upper frame of the entrance 4.

Also, at the bottom of the entrance 4 is a foundation 8 installed on the ground surface.
A lower guide 9 serving as a guide rail is installed on this base 8 to constitute a frame at the lower part of the entrance.

A frame body made of, for example, a C-shaped rope is constructed between both sides of the upper rail 7 and both sides of the guide 9, and the entrance 4 is
By forming a framework, airtightness is maintained in the upper, lower, left, and right directions, and the door 5 slides within these frameworks to open and close the entrance.

The upper rail 7 is configured integrally with a rail main body 7a having a U-shaped cross section and an opening 7c opening outward, and a holding part 7b having an L-shaped cross section that stands up at the upper part of the outer end of the rail main body 7a. It is made up of

The lower guide 9 is composed of a guide body 9a having an inverted U-shaped cross section and two parallel guide surfaces standing upwardly, and horizontal support plates 9b, 9b integrally formed at the lower end of the guide body 9a. .

The joint 2 consists of a joint body 11 and a U-shaped bolt 13.

The joint main body 11 has a pair of left and right hook pieces 12,
12 and the inner ends of the hook pieces 12, 12, and a top plate 16 that is integrally connected to the upper surface of each hook piece 12, 12 and the back plate 15. , 12 are formed with outwardly opening notches facing each other, and a pair of bolt holes are formed in the back plate 15 facing the bolts 13.

The upper rail 7 is attached to the pipe 1 via the joint 2 as described below.

That is, the rail 7 is arranged in a direction crossing the pipe 1, and then the hook pieces 12, 12 of the joint body 11 are inserted into the L-shaped holding part 7b of the rail 7, and the hook pieces 12 are inserted into the notch of the joint body 11. The upper surfaces of the holding parts 7b are inserted and fitted together. Next, insert the bolt 13 holding the pipe 1 into the bolt hole of the joint body 11, and tighten the nut 1 from the inside.
4 and 14, the joint body 11 is drawn toward the pipe 1 side, and at this time, the rail 7 is also pushed into the pipe 1 side via the joint body 11.

Therefore, by tightening the bolt 13 and nut 14,
The outer end of the upper surface 16 of the joint body 11 and the outer surface of the holding portion 7b of the rail 7 abut against the outer surface of the pipe 1, whereby the upper rail 7 is firmly fixed to the pipe 1 via the joint 7.

The lower guide 9 is the rail attachment device 1 of the present invention.
It is held in pipe 1 via 0.

The door 5 forms a rectangular door frame with two vertical frames 26, 26 and upper and lower horizontal frames 27, 27, and one or more reinforcing frames 2 are installed between the vertical frames 26, 26.
Each of these frames 26, 27, and 28 has a dovetail groove opening upward, and the vinyl sheet is held on the outer surface of the door 5 by holding a vinyl sheet in the dovetail groove 29 via an elastic locking line. is being expanded.

The vertical frame 26, the horizontal frame 27, and the reinforcing frame 28 have narrow openings, for example, a long frame 3 in the shape of a groove with a cross section.
0, and a support plate 31 extending from the side of the long frame 30 in the longitudinal direction.

The vertical frames 26, 26 have a support plate 31 protruding inwardly, and horizontal frames 27, 27 and reinforcing frames 28, 28 are connected between the support plates 31, 31 by pins, bolts, welding, or the like.

The long frame 30 of the upper horizontal frame 27 has an arbitrary number of
For example, two rollers 32 are rotatably connected via a shaft 33, a washer, and nuts 35, 36, and the rollers 32 are fitted from the outside into an opening 7c in the rail body 7a of the rail 7.
When the door 5 is suspended from the rail 7 via the roller 2 and the roller 32 slides guided by the rail 7, the door 5 slides left and right along the rail 7. For example, when the door 5 moves to the left, the entrance 4 is closed. ,
It is designed to open when moving to the right.

On the other hand, in the elongated frame 30 of the lower horizontal frame 27, the pipe 1 is inserted into the gap 20 between the guides 9, and is guided with the inner surface of the elongated frame 30 in contact with the outer guide surface of the guide body 9a of the guide 9. When the door 5 slides, it slides from side to side to minimize sideways movement.

Approximately U-shaped guide pieces 36, 37 are attached to the inner surfaces of the support plates 31 of the vertical frames 26, 26 at the top and bottom,
The upper guide piece 36 slides against the inner surface of the rail main body 7a of the upper rail 7, and the lower guide piece 37 slides against the inner guide surface of the guide main body 9a of the lower guide 9. Even if a pressing force is applied outward, the guide pieces 36 and 37 prevent the guide member 5 from shifting outward.

As described above, when the door 5 is attached, almost no gap is formed between the upper rail 7, the lower guide 9, and the door 5, and airtightness is maintained even higher.

According to the above door device, since the rail main body 7a is opened outward, the door 5 can be inserted into the rail main body 7a from the outside via the roller 32, and the guide main body 9a of the lower guide 9 can be inserted upward. Since it is now possible to stand up and bring the distance between the outer surface of the door 5 and the pipe 1 closer, when the door 5 is attached, the outer surface of the door 5 will be extremely close to the pipe 1 side, and as a result, the rail 7 and the guide 9
The room partitioned by the door 5 and the pipe 1 is extremely small and has good airtightness, making it possible to prevent outside air from entering.

There is no gap between the rail 7, the guide 9, and the left and right frames with the door 5, and the greenhouse is highly airtight, preventing outside air from entering and maintaining the room temperature inside the greenhouse.

The door 5 is opened and closed by the roller 3 while it is suspended.
2, the opening and closing speed is quick, and since there is no need to open the door wide when the worker enters the room, it is possible to minimize the intrusion of cold air.

The door 5 itself, the frame, the rails, and the guides all use the structural materials of the vinyl greenhouse, so no special materials are required.Moreover, these can be molded at the same time as the framework of the greenhouse, making assembly easy and reducing costs. This greatly improves work efficiency.

Since the holding part 7b is provided at the outer end of the rail main body 7a, this holding part 7b comes into contact with the pipe 1 to improve airtightness.

The guide body stands upward and can be installed close to the pipe side, so the door insertion space 20 can be made as small as possible.

Next, an embodiment of the rail attachment device of the present invention will be described in detail.

As shown in FIG. 1, the mounting device 10 includes a rail holding section 40 and a U that is a fixing member of the rail holding section.
It is composed of a bolt 41 in the shape of a U-shape, a bolt 42 in the U-shape, or a bolt 43 in the T-shape, and a nut 44 that is attached to and detached from these bolts.

The rail holding part 40 is connected to the front and rear brackets 45, 4.
6 and the left and right brackets 47, 48, and the front and rear brackets 45,
A pair of locking portions 4 consisting of rectangular shapes standing upright on 46
It consists of 9,50. One or more of the locking parts 49, 50 stand up along the longitudinal direction, in other words, along the extension direction of the lower guide 9, and the shape is not limited to the one shown, but rib-like or column-like shapes can also be used. .

As long as the locking portions 49 and 50 are upright, the shape of the bracket does not need to be box-like.

Each bolt 4 is attached to the left and right brackets 47 and 48.
1, 42, 43 through the bolt holes 51, 52,
53 is worn.

The fixing member of the rail holding part does not have to be a bolt, and a joint or the like can also be used. An example in which a rail attachment device is held on a support such as a pipe 1 is shown in FIGS. 4 to 8.

That is, FIG. 4 and FIG. 6 show an embodiment in which the pipe 1 is held, and this is an example in which the bolt 41 and the rail holding part 4 are held together.
It is a combination of 0.

When a U-shaped bolt 41 is inserted into the cylindrical pipe 1, and the tip of the bolt 41 is inserted into a bolt hole 51 and tightened with a nut 44, the rail holding part 40 is fixed inside the pipe 1. After fixing the rail holding part 40 while adjusting the height with respect to the pipe 1, when the lower guide 9 is pushed into the rail holding part 40 from above, the locking parts 49 and 50 lock into the guide main body 9a.
The lower guide 9 is held in the gap therebetween.

Similarly, in FIG. 5, when a C-shaped channel 1 is used as a support, a rail holding portion 40 is fixed using a bolt 42 corresponding to the support.

Similarly, FIGS. 7 and 8 show that when the dovetail frame 1 is used as a support, the holding part 40 is fixed using a bolt 43 corresponding to the support.

In this case, the flange 43a of the bolt 43 is locked to the inner surface of the dovetail groove 1a of the dovetail frame 1, and the bolt 43 is
3 is tightened with a nut 44.

<Effect of invention> According to the present invention, there are the following effects.

a Since the rail holding part has a locking part that stands up along the longitudinal direction, the lower guide rail, which has an inverted U-shaped cross section, can be easily attached by simply fitting it into this locking part. Since it can be removed simply by pulling it out from the stop, the installation and removal work is significantly improved.

b Since the rail holding part can be held at any position via the fixing member, the height can be adjusted freely.

c Since the rail holding part is fixed to the column,
This prevents the lower guide rail from being buried underground during long-term use.

d Because the rail holding part is fixed to the column,
The location to attach the lower guide rail has also been decided,
Thereby, there is no need to perform lateral alignment of the lower guide rail each time, and the lower rail can always be set at a constant and accurate position.
