Description

  The present invention relates to a locking structure of a horizontal shutter that is provided in an opening of a building and that can open and close the opening in a horizontal direction. The present invention relates to a provided locking structure and its auxiliary lock.

  The horizontal shutter provided at the opening of the building is composed of a plurality of required slats connected to each other in the horizontal direction, which can be horizontally moved in the opening of the building to open and close the opening. Yes, it moves to the accommodating part provided at the end of the opening and accommodates it, or it is folded into the accommodating part in the opening so that the opening is opened and moved from the accommodating part into the opening. Then, the opening is covered, and the leading edge of the opening is brought into contact with the opposite edge to make the opening shield.

  Normally, the opening is opened and closed by one or two horizontal shutters. According to one horizontal shutter, there is a housing portion on one side of the aperture, and the tip of the horizontal shutter that can be accommodated in this is provided. , Abutting against the opposite flange of the vertical frame at the other end of the opening. According to the two laterally extending shutters, the distal end of the laterally extending shutter that has accommodating portions on both sides of the opening and can be accommodated in one accommodating portion Is brought into contact with an opposing rod at the front end of a laterally retractable shutter that can be accommodated in the other accommodating portion, so that the opening is shielded.

  In addition, the horizontal shutter can be moved above or below the opening via wheels provided on the upper edge or the lower edge at regular intervals so as to facilitate horizontal movement within the opening. It is guided by a horizontal frame provided in the section and installed so as to be horizontally movable.

  By the way, when the opening in which the horizontal shutter is installed is made into a shielding shape by abutting the tip ridge and the opposite ridge, the tip ridge and the opposite ridge are fixed in this state so that they can be locked. The tip hook is provided with a locking structure, and the locking structure allows the locking member to appear and disappear from the tip hook by a locking / unlocking operation of a lock operating portion including a thumb turn or a key cylinder provided on the tip hook. It is like that.

  Up to now, as the locking structure, for example, a shaft member as a locking member can be projected and retracted vertically from the upper and lower end portions of the tip end, and the shaft member is inserted into the receiving hole of the upper and lower frames of the opening to lock the locking member. The horizontal shutter is provided with a locking structure that is often implemented, but the upper and lower shaft members come out of the receiving hole by bending and bending the distal end with the locking structure in a locked state. It is not desirable because the lock may be released without depending on the means.

  Therefore, as the locking structure provided in the distal end of the horizontal shutter, the upper and lower sickle locks arranged on the upper and lower portions of the distal end can be moved up and down by the locking / unlocking operation of the end locking / unlocking operation part. The upper hook and the lower hook are perforated in the upper and lower portions of the opposing hook, and the upper hook and the lower hook are hooked into the upper hook hole and the lower hook hole, respectively. It is desirable to have a locking structure that can be locked so that the locking is not released by the unauthorized means as described above (see, for example, Patent Document 1).

  However, even if the locking structure is such that the locking is performed by locking the upper hook and the lower hook of the opposite end of the tip rod as described above, the locking / unlocking operation portion is used with a proper means or key. If the unlocking operation is performed by unauthorized means, for example, so-called picking means or forcefully opening means using a jig such as a screwdriver, the link is driven, and the upper and lower sickle locks are driven. In addition, the locking will be released, and the upper and lower sickle locks will be locked to the upper and lower hooking holes by applying external force to the upper and lower sickle locks and forcing the link. The upper and lower sickle locks may be moved back into the tip cage and unlocked.

  Therefore, in the present invention, in the locking structure in which the tip hook and the counter hook are connected to each other by the upper and lower sickle locks, the link between the upper and lower sickle locks can be fixed. An object to be solved is to provide a locking structure for a horizontal shutter that is provided with an auxiliary lock so that it can be operated without requiring a separate operation in accordance with the locking of the main lock.

  In order to solve the above-described problems, the locking mechanism of the horizontal shutter according to the present invention is arranged in the upper and lower portions of the tip hook provided in the horizontal shutter that can move horizontally in the opening and make the opening shield. A main lock formed by connecting an upper sickle lock and a lower sickle lock to one lock operation part via a link having a lock part, and an auxiliary lock that urges a lock member against the link to make it press. Each of the upper and lower sickle locks of the tip hook by making the opening come into contact with the opposing hook of the member facing the tip hook and making the opening shielded, and then locking the lock operation part of the main lock The upper lock hole and the lower lock hole of the counter hook are locked to lock the main lock. At the same time, the lock portion of the link of the main lock becomes the lock member of the auxiliary lock and the auxiliary lock This is the first configuration.

A link that advances and retreats by operation is connected, and the link is rotated by being driven by the link.

  Further, in addition to any one of the first to fifth configurations, the upper and lower sickle locks may be symmetrical with each other, and this is the sixth configuration.

  Further, in addition to any one of the first to sixth configurations, the lock operating portion may be arranged at an intermediate position between the upper sickle lock and the lower sickle lock of the tip hook. The seventh configuration is adopted.

  In addition to any one of the first to seventh configurations, the auxiliary lock is configured such that a locking member is urged and accommodated by a coil spring in a frame having a cutout on a side surface. With the part of the link inserted between the locking member and the frame, the link moves forward and backward with the locking and unlocking of the main lock, and the locking part is located outside the frame when unlocked. Yes, the locking portion of the link is present in the frame during locking, and the locking member is preferably locked to the locking portion in the frame. This is the eighth configuration.

  Further, in addition to any one of the first to eighth configurations, the locking member may include an operation unit for pressing the locking member in a direction opposite to the urging direction. The ninth configuration is adopted.

  The locking mechanism of the horizontal shutter according to the present invention is configured as in the first to fourth configurations described above, so that the upper sickle and the lower sickle are connected via the link by the locking and unlocking operation of the locking operation portion of the tip hook. The lock is driven, and each of the upper and lower latch holes is locked or non-locked, with a main lock that can be locked and unlocked, and pressed against the link by the locking operation of the main lock. The locking member in the form of a sliding member relatively slides and locks to the locking portion of the link in the locked state of the main lock, thereby providing an auxiliary lock that can prevent the unlocking operation of the main lock.

  In addition, by adopting the configuration as in the fifth configuration described above, the upper and lower sickle locks can be surely made to appear and disappear from the tip hook by operating the locking operation part to unlock and unlock more stably. It can be latched to the latching hole and the lower latching hole respectively, and further, by being configured as in the sixth configuration, it comes into contact with the upper sickle lock and the upper latching hole, and the lower sickle lock and the lower latching hole. The leading edge hook and the opposite edge hook, each of which holds the stop hole, can be firmly connected.

  Further, by adopting the configuration as in the seventh configuration described above, the horizontal shutter is wide in the vertical direction, and the upper sickle lock and the upper latch are located at positions sufficiently separated from the upper and lower portions of the tip ridge. Even if each of the hole, lower sickle lock and lower retaining hole can be arranged and locked securely, it can be easily locked and unlocked, for example, at the height of the chest of an upright person, A lock operating portion of the main lock can be arranged.

  Further, by adopting the configuration as in the above-described eighth configuration, the auxiliary lock can be operated without a separate operation by the lock operation of the lock operation portion of the main lock, and the link is held in the frame body. The locking portion and the locking member can be securely locked, and the locked locking portion and the locking member are not easily detached even when an external force is applied to the link.
