Description

[Detailed Description of the Invention] [Industrial application] The present invention is used in a shutter curtain in which a plurality of shutter panels are vertically coupled by a hinge connection so that the shutter panels can rotate relative to each other. The present invention relates to a joint cover for covering an opening of a joint caused by the joint cover.

[Prior Art] A shutter curtain, which is composed of a plurality of panels, such as an over-sliding door, is used in which vertically adjacent panels are hinge-coupled to each other.

In this shutter curtain, the shutter curtains are arranged vertically in a straight line when the entrance of the building is closed, but when opening the entrance of the building, lift the shutter curtain and slide the shutter along the guide rails. Since the curtain is bent, the vertically adjacent shutter panels rotate relative to each other. Therefore, the upper and lower panel joints are separated from each other by this relative rotation to form the openings.

When the height of the shutter curtain is low, an operator may put his / her finger on the opening to close the shutter curtain.

[Problems to be Solved by the Invention] In consideration of the above facts, the present invention considers the above facts, and even when the vertically adjacent shutter panels relatively rotate to form an opening, an operator inserts a finger into the opening to open the shutter. The aim is to obtain a shutter panel joint cover that prevents manipulations.

[Means for Solving the Problems] The present invention is used for a shutter curtain in which a plurality of shutter panels are vertically coupled to each other by a hinge connection so that the shutters below the vertically adjacent shutter panels are used. It is characterized in that it is provided with a covering portion that is attached to the starter panel and that is formed so as to project from the panel surface side to the joint opening that is generated by the relative rotation of the shutter panel.

According to this structure, even when the shutter curtain relatively opens around the hinge and the shutter panel relatively rotates about the hinge to form an opening in the joint, the cover of the cover covers the opening. Therefore, a worker cannot insert a finger into the opening.

In addition to this, since the cover is attached to the lower shutter panel and is formed so as to project at a height that covers the joint opening from the panel surface side, the worker uses the projecting upper end of the cover. The operation of closing the shutter curtain by applying the descending force becomes easy.

[Embodiment of the Invention] FIG. 2 shows a shutter (oversliding door) to which the present invention is applied.

In this embodiment, a plurality of panels 12 are arranged vertically adjacent to each other, and these are pivotally supported by a hinge bracket 14 so as to be rotatable relative to each other, as shown in FIG. That is, the hinge bracket 14 has the shaft 18 fixed to the lower bracket 16 fixed to the lower panel 12 (12B), the upper bracket 22 is pivotally supported on the shaft 18, and the upper bracket 22 is attached to the upper panel 12. It is stuck to (12A). As a result, the upper and lower panels 12A and 12B can be relatively rotated about the shaft 18.

In addition, the hinge brackets 14A (Fig. 1) provided at both ends of the panel 12 in the width direction have the support shafts protruding in the horizontal direction,
A roller (not shown) is pivotally supported. These rollers are housed in a vertical guide rail 28 having a substantially U-shaped horizontal cross section, which is erected on both sides of the building entrance opening, and is guided by the vertical guide rail 28 to move up and down.

A horizontal guide rail 34 is connected to the upper end of the vertical guide rail 28 via a bent rail 32, and the rollers 26 move to the horizontal guide rail 34 via the bent rail 32 to move the plurality of panels 12 to the ceiling. It is designed to be horizontally stored.

The tips of the winding wire 36 are attached to the lower ends of the plurality of panels 12, and the winding wire 36 is attached to the bending rail 32.
The base of the winding drum 38 is arranged above the winding drum 38. The winding shaft 42 coaxially fixed to the winding drum 38 has its axis centered horizontally and is axially supported together with the winding drum 38 on a horizontal fixed beam 45, and receives the biasing force of the torsion coil spring 44 to move the winding drum 38. The winding wire 36 is urged in the winding direction. Therefore, when the panel 12 is manually lifted, the torsion coil spring
The reference numeral 44 is configured to urge the winding drum 38 to rotate in a direction in which the own weight of the panel 12 is cancelled, whereby the panel 12 can be lifted with a light operating force.

Panels 12A and 12B vertically adjacent to each other as shown in FIG.
The joint cover 48 according to the present embodiment is arranged at the joint. As shown in FIG. 3, the joint cover 48 has a front hanging portion 48B that covers the upper front surface of the panel 12B from one end of the web 48A that abuts against the upper end surface of the lower panel 12B, and the other end thereof. A rear drooping portion 48C that covers the upper rear surface of the panel 12B is projected from. Therefore, the web 48A, the front hanging part 48
B and the posterior hanging portion 48C are substantially U-shaped and open downward. The joint cover 48 is placed on the upper end of the panel 12B and is fastened together with the lower bracket 16 of the hinge bracket 14 through a mounting hole 52 formed in the rear hanging portion 48C by a mounting bolt (not shown).

From the junction of the web 48A and the front droop 48B, the back droop 48
A projecting portion 48D that slightly projects in the direction opposite to C is provided, and a covering portion 48E that is substantially parallel to the front hanging portion 48B and projects in the opposite direction is extended from the tip of this projecting portion 48D. Therefore, this covering portion 48E is used for the panel 1 as shown in FIG.
When 2 is arranged substantially vertically in the closed state of the building, it is slightly spaced from the front surface of the panel 12A and covers the lower front surface of the panel 12A.

Generally, the panel 12 is formed with a groove 54 extending horizontally in the vicinity of the lower end of the front surface thereof.However, when the panel 12 is vertical when the building is closed, the upper end of the covering portion 48E is the groove 5.
It is preferable to cover about 4 half. As a result, as shown in FIG. 1 (B), the panel 12A rotates relative to the panel 12B about the hinge bracket 14 to form an opening 56 between the lower end of the panel 12A and the upper end of the panel 12B. Moreover, the front surface of the opening 56 is covered by the covering portion 48E, and the worker cannot insert his / her finger into the opening 56.

Further, since the covering portion 48E is arranged apart from the front surface of the panel 12A by the length of the protruding portion 48D, the lower end portion of the panel 12A rotates relative to the panel 12B and the shaft 18, and the panel 12A is rotated.
Even when the lower end of the cover moves closer to the covering portion 48E than the state shown in FIG. 1 (A) in the course of its movement, the interference with the covering portion 48E is prevented.

This covering portion 48E has a through hole 58 formed at the lower end thereof,
If rainwater or the like gets into the protrusion 48D, it can be discharged. Therefore, except for this through hole 58,
The vertical cross-sectional shape of the joint cover is the same in the longitudinal direction (horizontal direction).

The lower bracket 16 is attached to the panel 12B via the rear hanging part 48C.
Since the upper bracket 22 is also fixed to the panel 12A via the flat plate 62 as a spacer, the mounting height is adjusted.

 Next, the operation of this embodiment will be described.

FIG. 2 shows a state in which the panel 12 has almost closed the entrance of the building. In order to open the entrance of the building, the panel 12 is manually lifted, but since it receives the driving force of the horizontal fixed beam 45 via the winding wire 36, it can be lifted with a light operating force.

Since the lifted panel 12 is guided from the upper panel 12 to the bent rail 32 and the horizontal guide rail 34, the panel 12A and the panel 12B are centered on the shaft 18 of the hinge bracket 14 as shown in FIG. 1 (B). And relative rotation, an opening 56 is formed between the joint between the lower end of the panel 12A and the upper end of the panel 12B. However, this opening 56 is again a plurality of panels when the panel 12 is guided to the horizontal guide rail 34.
Since 12 is accommodated in a straight line in the horizontal direction, it is in a close contact state.

When closing the entrance of the building again, a worker grips a part of the panel 12 and applies a moving force downward. As a result, the plurality of panels 12 are sequentially guided through the horizontal guide rails 34 and the bent rails 32 to the vertical guide rails 28, and the state shown in FIG. 2 is obtained. In this case, the opening 56 is formed between the panel 12A and the panel 12B guided by the bending rail 32, but since the covering portion 48E is arranged on the front surface of this opening 56, the worker is There is no need to inadvertently insert a finger into the opening 56 to pull down the panel 12, and there is a risk that the finger will be caught between the panel 12A and the panel 12B by continuing this pulling down operation. Nor.

Instead, since the worker is in a state where it is easy to grip the upper end of the covering portion 48E which is erected on the front surface of the opening 56,
The panel 12 can be easily pulled down to the closed state of the building by applying a downward force using the covering portion 48E. Even if a plurality of panels 12 are vertically straightened as shown in FIG. 1 (A) while the panel 12 is lowered with a finger on the upper end of the covering portion 48E, the covering surface of the covering portion 48E is rearward. Since the groove 54 of the panel 12 is arranged, the fingers are not caught between the covering portion 48E and the panel 12.

When the groove 54 is not formed on the front surface of the panel 12, the upper end portion of the covering portion 48E may be bent in a direction slightly separated from the front surface of the panel 12 to provide a space for inserting a finger.

[Advantages of the Invention] Since the present invention has the above-described configuration, even if an opening is formed in the panel joint by relative rotation of the shutter panel, there is no risk of pinching a finger in the opening, and the cover is on the lower side. Since it is attached to the shutter panel of the above, and is formed so as to project at a height that covers the joint opening from the panel surface side, the worker uses the projecting upper end of the covering to apply a downward force to close the shutter curtain. It has an excellent effect that the operation can be easily performed.
