Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pipe shutter attached to an opening of a building.

[Problems to be Solved by Prior Art and Invention] Generally, in this type of pipe shutter, a shutter curtain is formed by a plurality of pipes that are vertically connected in series through a connecting member such as a connecting link. Has been formed.

By the way, since such a shutter faces the inside of the building even when it is fully closed, it is often attached to the opening of a store, and in this case, it is opened and closed according to the opening and closing of the store. .

In the past, however, opening and closing the shutter curtains before and after the store was opened and closed was a hassle, so you had to dive in and out under the shutter curtain that was stopped at an intermediate position. Is the actual situation,
For this reason, the shutter curtain may be unexpectedly dropped, which is unfavorable for safety. In such a situation, the shutter curtain is often kept in a half-open state, which causes a problem in crime prevention.

[Means for Solving the Problems] The present invention was devised with the object of providing a pipe shutter capable of eliminating these drawbacks in view of the above-mentioned circumstances, and a pipe member In a pipe shutter that forms a shutter curtain by a plurality of pipes that are connected in series in the vertical direction, the pipe that forms the lower half side of the shutter curtain can be expanded and contracted by a nesting joint. It is characterized in that it is configured as a telescopic pipe, and a sliding door-like doorway that is opened and closed by the telescopic operation of the telescopic pipe is formed on the lower half side of the shutter curtain.

Further, according to the present invention, the safety and crime prevention of the pipe shutter can be remarkably improved by making it possible to enter and exit the entire shutter without opening and closing the entire shutter.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, 1 is a shutter curtain of a pipe shutter, and the shutter curtain 1 is formed by connecting a plurality of pipes 2 in series through a connecting link 3, and this is The forward / reverse rotation of the winding drum 5 installed in the shutter case 4 raises and lowers along the left and right guide rails 6, but these configurations are all conventional.

By the way, among the plurality of pipes 2, the one forming the lower half side of the shutter curtain 1 is the shutter curtain 1
In order to form the entrance / exit 1a in the lower half-side corner, the pipes 7 are formed to have a shorter width than the opening width, and these pipes 7 have a small-diameter pipe 8 having an outer diameter smaller than the inner diameter of the pipe 7. The small-diameter pipes 8 are inserted into and retractable from each other in the form of a telescopic joint, and the tips of the small-diameter pipes 8 are connected in series by door-end links 9 that are slidably guided by the vertically adjacent pipes 2. That is, in the shutter curtain 1 of the present invention, the doorway 1a which can be opened and closed by operating the small diameter pipe 8 in a sliding door shape is formed.

Further, 10 is a locking device provided on the door end link 9, which has an insertion opening 10a for a key 11 on its base end surface, and which is retracted in the front-rear direction by operating the key 11 at its tip. Although it has a claw 10b, when the entrance / exit 1a is in a closed state, the tip portion thereof penetrates through a hole 3a formed in the connecting link 3 in the guide rail 6, and the claw 10b which is projected in this state The reference numeral 10b restricts the rise of the shutter curtain 1 by engaging with the projecting inner projection 6a in the guide rail 6 and the entrance / exit 1a by engaging with the connecting link 3.
The opening operation of the is regulated.

In the embodiment of the present invention configured as described above, for example, when this is a pipe shutter attached to the opening of a store, even if the shutter curtain 1 is fully closed at the time of closing the store, before or after the store is closed. When entering and exiting, the small-diameter pipe 8 is operated like a sliding door so that it can enter and exit through the entrance 1a at the corner of the shutter curtain 1. Therefore, it is possible to enter / exit in a fully closed state in which there is no fear of accidental fall without going in and out as if going in and out through the shutter curtain 1 in an intermediate stop state where there is a fear of unexpected accidental fall. As a result, the safety of the pipe shutter can be significantly improved. Moreover, since the entrance / exit 1a is opened / closed every time the entrance / exit is entered, the crime prevention performance can be significantly improved as compared with the conventional case in which the shutter curtain 1 is maintained in the intermediate stop state.

Further, in the embodiment, the locking device 10 for restricting the opening of the entrance / exit 1a is provided, but this is also used as the locking device for restricting the opening of the shutter curtain 1, so that the parts are It can greatly contribute to the reduction of points and the simplification of the structure.

[Advantages] In summary, since the present invention is configured as described above, a plurality of pipes are connected in series in the vertical direction via a connecting member to form a shutter curtain. Since the pipe forming the lower half side of the shutter curtain is configured to be expandable and contractible by the telescopic joint, the lower half side of the shutter curtain has a sliding door-like entrance that opens and closes by the expansion and contraction operation of the expansion pipe. Will be formed. Therefore, if this product is installed in, for example, the opening of a store, it will be hidden under the shutter curtain in an intermediate stop state where there is a risk of accidentally falling before or after the shutter curtain is closed. Without going in and out,
It is possible to enter and exit through the sliding door-like door while the shutter curtain is fully closed, and as a result, the safety of the pipe shutter can be significantly improved. Moreover, in this case, since it is not necessary to maintain the shutter curtain for entering and exiting in the intermediate stopped state, the crime prevention property can be remarkably improved.
