Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a curtain device applied as a partition to a doorway of a factory or a warehouse.

[0002]

2. Description of the Related Art Conventionally, as a curtain device of this type,
For example, the one shown in FIG. 5 is known. The curtain device 50 basically has a flexible curtain 51.
And a plurality of pockets 52 formed at predetermined intervals in the front-rear direction of the curtain 51 and opened at the top and bottom, and each pocket 5
A runner 5 provided above the curtain 51 where 2 is located
3, a curtain rail 54 provided on the top side for movably guiding each runner 53, and an aggregate 5 which is inserted into each pocket 52 and whose upper end is connected to each runner 53 and which has rigidity
5, a drop rod 56 provided at the bottom of each aggregate 55, and a drop receiver 57 provided on the ground side to which each drop rod 56 is detachably engaged. The aggregate 55 is made of a metal pipe or the like.

Thus, in such a system, when the curtain is expanded from the contracted state, each runner is moved along the curtain rail to expand the curtain. afterwards,
The drop bar is hooked on the drop catcher, and the curtain is kept in an extended state. To make the curtain in the stretched state contracted,
The procedure is the reverse of the above. When an external force such as wind acts on the curtain in the stretched state, the curtain has flexibility, but since the rigid aggregate is inserted in the pocket and the drop bar is engaged with the drop receiver. , The curtain does not swing or roll up greatly.

[0004]

However, since such an aggregate has a considerable weight and is a rigid body, the expansion / contraction operation of the curtain, that is, the opening / closing operation of the curtain cannot be easily performed, and the flexibility of the curtain is high. The curtain was liable to be damaged early due to the friction between the curtain and the rigid aggregate.

The present invention has been made in view of the above problems and was devised to solve the problem. The object of the present invention is to easily open and close the curtain and extend the life of the curtain. It is to provide a curtain device that can be done.

[0006]

The curtain device of the present invention basically comprises a flexible curtain and a plurality of pockets formed at predetermined intervals in the front-back direction of the curtain and opened at the top and bottom. , A runner provided on the upper part of the curtain where each pocket is located, a curtain rail provided on the top side to movably guide each runner, and inserted in approximately the upper half of each pocket to connect the upper end to each runner Flexible cartilage material, a tensioning means that is inserted into approximately the lower half of each pocket and has an upper end connected to each cartilage material to tension the cartilage material, and a hooking tool provided at the lower end of each tensioning means And a hooking device provided on the ground side and on which each hooking device is detachably hooked.

When the curtain is extended from the contracted state, each runner is moved along the curtain rail to bring the curtain into the extended state. Then, the tensioning means is extended and the hooking tool is hooked on the hooking tool. Then, while the cartilage material is being tensioned by the tensioning means, the curtain is kept in the stretched state. When the curtain in the expanded state is made to be in the contracted state, the procedure is the reverse of the above. When an external force such as wind acts on the curtain in the stretched state, the curtain and the cartilage material have flexibility, and since the tensioning means is elastically expandable and contractible, the entire curtain is flexibly deformed. The curtain does not swing or roll up greatly.
Since the cartilage material is relatively light and flexible, and the tensioning means can elastically expand and contract, the expansion and contraction operation of the curtain, that is, the opening and closing operation can be easily performed. In addition, since the cartilage material and the tensioning means have a high affinity with the curtain in terms of flexibility and elastic expansion and contraction, the curtain is not damaged early,
Therefore, the life can be extended.

The tension means is a cylinder, a spring holder movably provided in the cylinder, a rod provided in the spring holder and penetrating from the head side of the cylinder, a spring holder in the cylinder and a head side of the cylinder. And a compression spring interposed therebetween. By doing so, as compared with, for example, a mere tension spring only, after the compression spring is compressed to the maximum extent, further extension is restricted as a tensioning means, so that it depends on external force such as wind. There is no fear that the curtain will bend greatly and swing or roll up.

It is preferable that the rod is made of a flexible member and has a hooking tool at its tip. In this way, the number of flexible portions can be increased to improve the affinity with the curtain, and the engaging and disengaging work between the hook and the hook can be facilitated.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view in which a part of the curtain device of the present invention is vertically cut. FIG. 2 is a front view of FIG.
FIG. 3 is an enlarged transverse plan view of FIG. 1. FIG. 4 is an enlarged view of a main part of FIG.

The curtain device 1 is mainly composed of a curtain 2, a pocket 3, a runner 4, a curtain rail 5, a cartilage material 6, a tensioning means 7, a hooking tool 8 and a hooking tool 9, which is used in a factory or a factory. It is applied as a partition at the entrance and exit of warehouses.

The curtain 2 has flexibility, and in this example, it has a rectangular shape, is made of cloth, synthetic resin sheet, or the like, and has a size that blocks an entrance / exit of a factory, a warehouse, or the like. There is.

The pockets 3 are a plurality of pockets provided at predetermined intervals in the front-rear direction of the curtain 2 (left-right direction in FIG. 1) and opened at the top and bottom. It is provided every 1 m and has a substantially U-shaped cross section at the same height as the curtain 2, and the curtain 2 has the same quality on the front side (left side in FIG. 2) and the height is substantially the same. It is formed by slackening the same strip-shaped pocket piece 10 and applying it, and attaching both ends to each other.

The runner 4 is provided on the upper part of the curtain 2 located in each pocket 3, and in this example, the bracket 11 and the left and right rollers provided on the upper part of the bracket 11 so as to be rotatable about the left-right axis. And a through hole 13 is formed in the lower portion of the bracket 11. On the other hand,
Through holes 15 are formed in the upper portion of the curtain 2 where the pockets 3 are located by the eyelet fittings 14. Thus, the runner 4 and the curtain 2 are connected by the shackle 16. The shackle 16 includes a shackle body having a substantially U shape, and an eyebolt that opens and closes an open portion of the shackle body.

The curtain rail 5 is provided on the top side and movably guides the runners 4. In this example, the curtain rail 5 has a substantially C-shaped cross section and is attached to the upper frame of the entrance or the like with the open portion facing downward. To be

The cartilage material 6 is flexible and is inserted into the upper half of each pocket 3 and has its upper end connected to each runner 4. In this example, it is a chain and its upper end is a shackle 16. The runner 4 with the upper part of the curtain 2
Are linked to.

The tensioning means 7 is inserted into substantially the lower half of each pocket 3 and has the upper end connected to each cartilage material 6 to tension the cartilage material 6. In this example, the cylinder 17 and the inside of the cylinder 17 are tightened. Movable spring holder 18
A rod 19 provided in the spring holder 18 and penetrating from the head side of the cylinder 17, and a compression spring 20 interposed between the spring holder 18 in the cylinder 17 and the head side of the cylinder 17. There is. The spring holder 17 is a crimp stopper made of aluminum. The rod 19 is a wire rope which is a flexible member, and a tube made of a synthetic resin is fitted on the outside of the rod 19 although not shown.

The hooking device 8 is provided at the lower end of each tensioning means 7. In this example, the hooking tool 8 is a substantially S-shaped hook and is provided at the tip of the rod 10 of the tensioning means 7.
That is, the wire rope, which is the rod 19, is inserted into the closed ring portion of the hooking device 8 to form a ring shape, and then the hooking device 8 is connected by being crimped by the crimping stopper 21 made of aluminum.

The hooking device 7 is provided on the ground side so that each hooking device 8 can be detachably hooked. In this example, the hooking device 7 has an inverted U shape and is recessed at a predetermined interval on the ground 22. It is planted in the recess 23 so as not to project further.

Next, the operation will be described based on such a configuration. When the curtain 2 is expanded from the contracted state, each runner 4 is moved along the curtain rail 5 and the curtain 2 is expanded. After that, the hooking device 8 is hooked on the hooking device 9 while extending the tensioning means 7. Then, the cartilage material 6 is tensioned by the tensioning means 7 and the curtain 2 is kept in the stretched state (see FIG. 1). The contracted state of the curtain 2 in the expanded state is performed in the reverse order of the above.

When an external force such as wind acts on the curtain 2 in the stretched state, the curtain 2 and the cartilage material 6 have flexibility, and the tensioning means 7 is elastically expandable and contractable. The curtain 2 is flexibly deformed, so that the curtain 2 does not rock or roll up greatly.

Since the tensioning means 7 is provided with the cylinder 17, the spring holder 18, the rod 19 and the compression spring 20, the compression spring 20 is compressed to the maximum extent as compared with, for example, one constituted by only a tension spring. After that, since the tensioning means 7 is restricted from further extension, there is no fear that the curtain 2 is largely bent and rocked or rolled up by an external force such as wind. Cartilage 6
Is relatively light and flexible, and the tensioning means 7 is elastically expandable and contractable, so that the expansion and contraction operation of the curtain 2, that is, the opening and closing operation can be easily performed. Further, since the cartilage material 6 and the tensioning means 7 have a high affinity with the curtain 2 in terms of flexibility and elastic expansion and contraction, the curtain 2 is not damaged at an early stage and therefore the life can be extended.

Although the cartilage material 6 is a chain in the above example, the cartilage material 6 is not limited to this and may be a wire rope or the like. Although the compression spring 20 is used as the tensioning means 7 in the previous example, the tensioning means 7 is not limited to this, and may be, for example, rubber or a tension spring. Although the rod 19 is a wire rope in the above example, the rod 19 is not limited to this and may be, for example, a metal rod or the like.
