Description

TECHNICAL FIELD The present invention relates to a slide mechanism and a movable part of the slide mechanism, and more particularly to a slide mechanism for sliding members to be slid horizontally inside or outside a vinyl house.

Since crops are grown in vinyl greenhouses, heat retention, heat insulation, light shielding, and ventilation are also required. As the opening/closing mechanism, there is a technique as described in Patent Document 1, for example. This technique uses a winding mechanism to raise and lower the outer sheet. There is also a lining type, but it also has a structure in which it can be moved up and down using a hoisting mechanism.

Moreover, in a vinyl house, a sliding door structure is used for an entrance door. For example, the one described in Patent Document 2 is of a lower rail running type.

Further, as shown in Patent Documents 3 and 4, the upper rail is rectangular C-shaped and opens downward, and has a structure in which two rollers are hooked on the bottom side (see also FIG. 19). In general, there is a structure for hanging items that can be opened and closed by sliding, such as curtains and curtain doors, but rails that are attached to the top are used. The rail is open downward, and a hook is hung from the bottom side as shown in Patent Documents 3 and 4, and the curtain or the like is opened and closed by sliding the hook.

However, the technique described in Patent Literature 1 has a structure in which the entire outer sheet is rolled up, and there is a problem that the apparatus including the device is large. If the sheet is not the outer lining but the inner lining, the structure is such that the entire lining sheet is rolled up so as to be located on the inside on the frame structure, and the same problem exists.

On the other hand, in order to use rails such as curtains and curtain doors that are used in ordinary houses for the lining sheet, the wall surface of the house has a shape that draws an arc toward the top position. There is also the problem that it is not easy to slide.

Moreover, with the technique of Patent Document 1, there is also the problem that it is difficult to open only a part of the door instead of the whole door or to close only a part of the door. Normally, lining sheets are used during the day and are not needed at night, but there are cases where detailed measures are necessary from the viewpoint of heat retention, heat insulation, light shielding, and ventilation. Users have high hopes for part of the opening and closing, because it reduces the opening and closing load and does not require a device such as a hoisting mechanism.

Furthermore, in the case of a structure of a lower rail traveling type sliding door as an entrance door as shown in Patent Document 2, the door is usually attached to either the inside or the outside of the house. That is, it is not done in a suspended form, with doors on both the outside and the inside. In addition, even when the upper rails as shown in Patent Documents 3 and 4 are used, since two rollers are required on the left and right sides, the width may be taken, so that the door can be positioned either inside or outside the house. can be attached to On the other hand, from the viewpoint of heat retention, heat insulation, light shielding, etc., it is realistic to install two large upper or lower rail running sliding door structures even if it is expected that there are entrance doors on both the inside and outside. Instead, at least one is a hanging slide mechanism like a curtain, and if it is a door using a lining sheet, for example, it can be rational from the viewpoint of heat retention, heat insulation, light shielding, and ventilation. , there is currently no such thing.

Therefore, it is an object of the present invention to provide a sliding mechanism with a simple structure for horizontally sliding members to be slid, such as lining sheets and doors for heat retention, heat insulation, and light shielding inside or outside a greenhouse. With the goal.

A first aspect of the present invention is a slide mechanism for horizontally sliding a member to be slid inside or outside a greenhouse, which is horizontally disposed inside or outside the greenhouse. A rail that is open except for the downward opening direction, an engaging portion that engages with the rail so as not to come off, a plate-like portion in which the engaging portion is formed, and the plate-like portion. It has a spring means or a hook portion to which one end is attached, and the member to be slid is connected to the other end of the spring means or the hook portion.

From this point of view, by using the spring means, an urging force acts, and even if the wall surface of the house has a shape that draws an arc toward the top position, it can be slid while releasing the force of gravity. , the slide mechanism can function.

According to a second aspect of the present invention, in the first aspect, the rail can be used as a strip material for fixing a synthetic resin film used in the vinyl house, and the engaging portion is the rail It is characterized by having a spatial clearance between

From this point of view, the material that is used as the strip material for fixing the synthetic resin film can also serve as the rail. Moreover, since the engaging portion has a spatial margin with respect to the rail, the friction in sliding can be reduced together with the urging force of the spring means.

According to a third aspect of the present invention, in the second aspect, the rail is also a film fixing member for covering and fixing the synthetic resin film on the house construction material, and the rear side thereof is fixed to the house construction material. left and right side walls formed by raising the left and right edges forming the longitudinal sides of the bottom wall inward and upward, respectively; and a folded portion formed by folding back so as to have a columnar space.

According to a fourth aspect of the present invention, in the first aspect, the rail has a C-shaped cross section.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the engaging portion is a rotating roller portion.

From this point of view, by using the roller portion, the friction in the slide can be made smaller.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the plate-like portion has an elongated shape, the engaging portion is formed on one end side of the plate-like portion, and the The spring means is attached to the other end side of the plate-like portion.

From this point of view, due to the elongated shape, the weight of the member to be slid is not applied almost directly below the rail, but is applied to the rail at an offset position, so that the load on the slide mechanism can be reduced. Friction can be reduced.

According to a seventh aspect of the present invention, in any one of the first to fifth aspects, there are a plurality of the engaging portions, and the plurality of engaging portions are formed on the plate-like portion.

By using a plurality of engaging portions, the load of the member to be slid is distributed to a plurality of members, and the burden on each member can be reduced by distributing the load on the slide mechanism.

According to an eighth aspect of the present invention, in the seventh aspect, the plate-like portion has a triangular shape, one end of the spring means is attached to one of its vertices, and the other two vertices It is characterized in that an engaging portion is formed at each of the positions.

A ninth aspect of the present invention is a movable portion of a slide mechanism for horizontally sliding a member to be slid along a rail horizontally disposed inside or outside a vinyl house, The rail is arranged to be open except for the downward opening direction, and includes an engaging portion that engages with the rail in a non-disengaging state, and a plate-like portion on which the engaging portion is formed. and a spring means or hook portion, one end of which is attached to the plate-like portion, and the member to be slid is connected to the other end of the spring means or the hook portion.

According to the invention of each aspect, members to be slid, such as lining sheets and doors for heat retention, heat insulation, light shielding, and ventilation, can be slid inside the vinyl house with a simple structure.
