Description

  The present invention relates to a greenhouse door device provided at an entrance of a greenhouse, which is a greenhouse, and more particularly to a greenhouse door device provided with a mounting bracket for attaching a reinforcing frame that also serves as a gap plug.

    2. Description of the Related Art Conventionally, in a greenhouse having an entrance / exit on a wife surface, a rail is disposed along the entrance / exit, and a door that opens and closes the entrance / exit is supported on the rail so as to be movable. The door is typically a sliding door type that moves along a lower rail via a roller, or a sliding door type that moves while being suspended via a roller along an upper rail.

  Further, one rail is used according to the size of the entrance / exit, or a single rail is used by adding a plurality of rails along the longitudinal direction.

    In such a conventional rail, for example, a rail that can be obtained simply and at low cost by press-molding a metal plate base material is used. However, a door guided by this rail receives a wind due to a strong wind or a gust of wind. A large stress in the same direction acts on the rail due to the displacement of the door at this time, and the rail may be bent in the leeward direction.

    Therefore, when the bending behavior increases, there is a problem that the upper part of the door is detached from the rail, and the entrance / exit of the greenhouse is opened.

  Furthermore, the suspension door type door has a problem that the upper rail is bent downward due to the weight of the door.

In addition, at least two struts for supporting the rail stand up on both sides of the entrance and exit, and a transparent sheet is extended above each strut via a seat support frame. A gap corresponding to the thickness of the column was formed on the outside, and there was a problem that outside air entered the greenhouse through this gap.
For this reason, in order to solve the above problems, for example, a door device as shown in Patent Document 1 has been developed.

  As shown in FIG. 8, this door device covers a pair of opposing rails 1 with end portions abutted against each other, a door D <b> 1 whose upper portion is movably inserted into the rail 1, and an outer side of the rail 1.

  The joint 20 includes an upper plate 20a that holds the upper portion of the rail 1, side plates 20b and 20c that are connected downward on both sides of the upper plate 20a, and mounting holes 20d that are formed in one side plate 20b. The reinforcing frame 30 includes a hollow pipe 30c having a dovetail groove 30a in the front portion and a mounting hole 30b in the back portion.

  Then, the mounting frame 40 is inserted into the mounting holes 20d and 30b and rotated while the reinforcing frame 30 is coupled to the joint 20, whereby the reinforcing frame 30 is connected to the front side of the rail 1 so that the rail 1 is connected. In addition to reinforcing, the reinforcing frame 30 closes the gap on the front side of the rail 1 to prevent intrusion of outside air from the arrow A.

  However, recently, the reinforcing frame 30 is provided with the gap 30b for inserting the mounting bracket, so that the strength of the gap 30b reinforcing frame 30 itself is not sufficient, and a hollow square pipe type that does not mold the gap 30b is used. It has been developed.

  As a result, the wedge-type mounting bracket 40 is no longer used, and a door device as described in Non-Patent Document 1 is installed instead.

  One of the door devices is shown in FIG. 9, and the other door device is shown in FIG.

  The door device shown in FIG. 9 includes a pair of opposing rails 1 whose end portions are butted against each other, a door D1 in which the upper part is movably inserted into the rail 1, and the rail 1 covering the outside of the rail 1. A joint 52 that connects the reinforcement frame 3, the reinforcement frame 3 that also serves as a gap blocker disposed along the rail 1 below the side of the rail 1, and a mounting screw 51 that attaches the reinforcement frame 3 to the joint 52. is there.

  The joint 52 has an upper plate 52a that holds the upper portion of the rail 1 and side plates 52b and 52c that are connected to both sides of the upper plate 52a or downward, and the reinforcing frame 3 has a dovetail groove on the side. It is composed of a hollow square pipe 3b provided with 3a, and the reinforcing frame 3 is coupled to the front side plate 52b of the joint 52 via screws 51.

  On the other hand, the door device shown in FIG. 10 includes a pair of opposing rails 11 that are end-to-end, a door D2 that is movably inserted into the rail 11 via rollers R and R, A joint 12 for connecting the rail 11 to the rail 11, a reinforcement frame 3 serving as a gap closing disposed along the rail 11 below the side of the rail 11, and the reinforcement frame 3 being attached to the rail 11 As shown in FIG. 9, the lower portion of the mounting plate 53 is fixed to the reinforcing frame 3 via the screws 51, and the upper portion of the mounting plate 53 is fixed with bolts B and nuts N.
