Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a lower rail traveling type sliding door device that opens and closes an entrance / exit provided on a gabled surface of a vinyl house.

[0002]

2. Description of the Related Art In general, entrances and exits of vinyl greenhouses are provided on a gable face, and it has become common sense in recent years to install a door for opening and closing the entrance and exit. Traditionally, doors for greenhouses were also revolving type doors, but recently there are many sliding door types.

The conventional sliding door device for a vinyl house is mainly a suspension type in which a sliding door is suspended from an upper rail by a door roller. The reason for this is that the lower rail is easily polluted by mud and dust from the environment, and it is often bent by people and vehicles, which makes it difficult to move the sliding doors and is installed on the ground. It is difficult to maintain the level of the lower rail due to the unevenness of the ground, and it is difficult to maintain the level. Then, the lower rail is pushed up by freezing of the ground and the frost pillar, and as a result, the mobility of the sliding door is impaired.

[0004]

As a structural characteristic of the hanging type sliding door device, the work of mounting and installing it on the end face of the vinyl house is extremely troublesome and troublesome. That is, since the length of the upper rail is limited and a working space cannot be secured, it is not possible to implement a method in which the door roller is first attached to the upper portion of the suspension sliding door and fitted in the longitudinal direction of the rail. In addition, a method of attaching a door roller to the upper part of the hanging sliding door first, combining it with an upper rail, and then retrofitting the upper rail to the frame of the greenhouse is also possible, unless heavy machinery is used, such as sliding doors and upper rails. The total weight is too large to be implemented. In the end, it is customary to first attach the upper rail to the frame of the greenhouse, and to lift and connect the sliding door from below to the suspension type door roller attached to the rail. Even in this case, the work during the temporary lifting of the sliding door to achieve the coupling with the door roller is extremely heavy work. As a matter of course, when the sliding door finally installed as described above is damaged and needs to be replaced,
Alternatively, even when the seat is stretched over the sliding door due to aging deterioration (useful life) or damage, the sliding door must be temporarily removed from the upper rail door roller, so maintenance is extremely troublesome and extremely troublesome. It is the content.

Recently, there has been a trend toward an increase in the size of vinyl greenhouses, and inevitably the size of sliding door devices has also increased. Even if the greenhouse grows in size, the frame of the house is only a simple structure with pipes assembled by joints after all, and its proof capacity is limited. Therefore, in order to support and open / close the large-sized hanging type sliding door device, the load on the sliding door device is so large that the frame of the house is distorted, and the opening / closing operation of the sliding door device is disturbed.

Particularly, the large-sized sliding door device is greatly affected by the wind load, and a rattling noise caused by wind pressure,
Alternatively, the squeaking noise and other noises during the opening and closing operation are bothersome to the ears, which is a problem that the user strongly desires to solve. Therefore, an object of the present invention is to prevent opening and closing operations from being disturbed by mud and dust that are of concern for the lower rail traveling type, and to facilitate the work of installation and installation and the subsequent maintenance, and to load the house frame. (EN) It is possible to provide a lower rail traveling type sliding door device which can reduce the burden and can rationally solve the problems of rattling noise, squeaking noise and other troublesome noises.

A further object of the present invention is that a required length portion of the lower rail centering on the width of the entrance and exit can be attached and detached as necessary, and it interferes with the entrance and exit of various vehicles such as a tractor into and from the greenhouse. It is an object of the present invention to provide a lower rail traveling type sliding door device that does not become a problem.

BEST MODE FOR CARRYING OUT THE INVENTION A lower rail traveling type sliding door device for a vinyl greenhouse according to the invention described in claim 1 opens and closes an entrance / exit 2 provided on the end face of the vinyl greenhouse 1 as shown in FIG. It is suitably implemented as a thing. Figure 1
2 shows the overall construction of the lower rail traveling type sliding door device according to the present invention, and FIG. 2 is installed in the vinyl house 1, the two double-opening sliding doors 4 and 4 are fully opened, and the lower rail 3 is detachable. The state where the rail 3'of a part is removed is illustrated.

More specifically, a lower rail 3 is installed along the lower edge of the entrance / exit 2. In the hollow portion of the inverted channel steel frame 4a forming the lower side of the sliding door 4, a door roller 5 is mounted which rolls on the lower rail 3 (FIG. 3). In the embodiment of FIG. 3, the lower rail 3
Has a substantially hat-shaped cross section, and is used in a mode in which the horizontal leg portions 3a, 3a at the lower portions on both sides thereof are placed on the ground and the convex portion 3b is erected upward. This lower rail 3
With the rail receiver 7 and the U bolt 8 installed by being embedded in the ground, the leg portion 3a is firmly fixed to the column 9 forming the frame of the greenhouse 1. It is configured that the wheels of the door roller 5 ride on the protrusion 3b. Therefore, the entire weight of the sliding door 4 is directly transmitted to and supported by the ground via the lower rail 3, and the load of the framework of the greenhouse 1 is not imposed. Therefore, this lower rail traveling type sliding door device is suitable for a large vinyl house.

Further, even if dirt or dust falls on the convex portion 3b of the lower rail 3, it usually rolls down to the lower leg portion 3a. Even if mud or dust adheres to the convex portion 3b, when the door roller 5 travels and passes once, the door roller 5 is crushed or pushed away by its weight, or is expelled with vibration, so that the vehicle may not travel. It does not hinder. The mud and dust that have fallen onto the legs 3a can be easily cleaned as needed.

On the outer peripheral surface of the wheel of the door roller 5 shown in FIG.
A V-shaped recessed groove 5a is formed so as to straddle the convex portion 3b of the lower rail 3 so as to prevent the wheel from derailing as much as possible. However, the groove 5a of the wheel is not
It does not have to be V-shaped as long as it does not straddle over the convex portion 3b and does not come off. It can be implemented with a U-shaped groove or other groove. The wheels of the door roller 5 are also preferably made of synthetic resin so as not to generate a squeaking noise, but in some cases, those manufactured as a metal die-cast product are also used.

At the front and rear ends of the lower part of the sliding door 4,
In anticipation of the wheel removal prevention function of the door roller 5, a wheel removal prevention stopper 17 is provided just in case. The derailment prevention stopper 17 is preferably made of synthetic resin and is formed in a shape straddling the convex portion 3b of the lower rail 3 as shown in FIG. 7A.
The sliding door 4 is fitted into the hollow portion of the lower frame 4a, and is fixed by screws 18 from below toward the frame 4a. However, the material for the wheel removal prevention stopper 17 is not limited to the synthetic resin, but a metal die-cast product,
It is also possible to use pressed products of steel plates. The wheel removal preventing stopper 17 also has a function of repelling and removing mud and dust attached to the lower rail 3 ′ as the sliding door 4 travels. FIG. 7B exemplifies a derailment prevention stopper 17 as a pressed product of a steel plate.

On the other hand, a guide rail 6 is provided along the upper edge of the entrance 2 to restrain and guide the upper portion of the sliding door 4. In the embodiment shown in FIG. 3, the guide rail 6 is composed of an inverted channel steel member, and as shown in detail in FIG. It is fixed. As shown in FIG. 6, the upper side of the sliding door 4 is formed by using a mold member having a sheet fixing groove 4d for the vertical member 4b and the horizontal member 4c, and is fitted into the groove of the guide rail 6. Therefore, the guide rail 6
Has a considerable allowance for the vertical displacement of the sliding door 4.

The upper side of the sliding door 4 is formed on the upper side of the sliding door 4 as a means for preventing the squeaking noise when the sliding door 4 moves and the noise of the sliding door 4 shaking and shaking due to wind pressure or the like. A slider 11 is attached to the guide rail 6, which slightly protrudes from both inner and outer side surfaces of the vertical member 4b and the horizontal member 4c and directly contacts the inner surface of the guide rail 6 with low friction. The slider 11 shown in FIG. 6 has a vertical slit 11a and a vertical member 4b.
It is fitted from above so as to straddle the flat plate portion and fixed by a set screw 16 from the lateral direction. This slider 11 also
From the viewpoint of preventing the squeaking noise, it is preferably made of synthetic resin, but as long as it has a shape that flatly hits the inner surface of the guide rail 6, a slider of a metal die-cast product or a pressed product such as a steel plate may be used. It can be used as well.

In any case, since the slider 11 works, the sliding door 4 is large, and rattling noise hardly occurs even if it receives a large wind pressure. Similarly, no squeaking noise is generated with the guide rail 6. The slider 11 is provided with an upper limit restricting portion 15 that projects laterally from the lower portion thereof. As shown in FIG. 3, the upper limit regulating portion 15 is fixed at a position where a gap h of about 10 mm is provided between the lower edge of the guide rail 6 and the upper and lower limit regulating portion 15 so as to regulate the undesired vertical displacement of the sliding door 4, and thus the door roller. It is configured to prevent the derailment of item 5. The height of the slider 11 is properly adjusted by loosening the set screw 16.

As described above, the lower rail 3 has the doorway 2
The rail 3'having a required length centering on the opening width L of the is removable, and the rail 3'is removed as shown in FIG. 2 so that a tractor, an automobile, a cart, and other vehicles can be installed in the vinyl house 1. It is designed so that it does not interfere with comings and goings.
However, if necessary, the lower rail portion that is longer than the width L of the frontage can be detachably configured.

As means for attaching and detaching the rail 3 ', in the embodiment shown in FIG. 4, at the inner end of the lower rail 3 on the fixed side, the cross-sectional shape is similar to the thickness (about 2.3 mm). The length of the overlapped portion 12 that has been reduced (drawn) is 40
It is formed about mm. Therefore, the removable rail 3'can be connected by overlapping its end portion on the overlapped portion 12 and does not cause a step at the connection portion, so that the sliding door 4
The door roller 5 moves smoothly. Further, since the parts are superposed and joined, the strength of the connecting portion is also high. Moreover, as means for mechanically restraining the connecting portion of the lower rail 3, horizontal hat-shaped steel legs 3a, 3a are shown in FIG.
The sliding type joint 13 is used to fix the overlapped part by sandwiching it from above and below.

The width W of the sliding door 4 in the embodiment shown in FIG. 2 is usually about 1 m to 1.2 m, and therefore the frontage width L of the doorway 2.
Is about 2m to 2.4m. The rail 3'having a length close to the width L of the frontage is configured to be removable. Therefore, the detachable rail 3'has a length of approximately 1.5 m to 2.2 m according to the above-mentioned dimensional example. Therefore, the tractor, the automobile, the cart, and other vehicles can move in and out of the greenhouse 1 as traveling on the ground as a result of removing the removable rail 3 '.
Not only that, in the part where the rail 3'is removed,
As a feature of the lower rail traveling type, it is possible to easily fit and remove the sliding door 4 with respect to the upper and lower rails 3 and 6. Therefore, in the case of this lower rail traveling type sliding door device, an assembly method (construction method) in which the lower rail 3 and the upper rail 6 are preliminarily attached to the frame of the greenhouse 1 and the sliding door 4 is fitted later can be implemented. The installation of the sliding door device is extremely easy. Inevitably, replacement of the damaged sliding door 4 or replacement of the sheet stretched on the sliding door 4 can be performed relatively easily.
