JP2551155Y2 - Prevention of detachment of linked shutter - Google Patents

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a device for preventing a separated shutter from coming off in an aluminum sash.

[Conventional technology]

A conventional connection porosity is disclosed in Japanese Utility Model Publication No. 1-31741. In this technology, one end of a connecting member is pivotally connected to one shutter, and the other end is movably attached to another shutter. A roller is attached to the side frame of the shutter so as to be exposed from the side of the frame, and such a connecting member is mounted on both upper and lower side frames or one side frame of the shutter.

Further, the door stop side and the door bottom side of each shutter are overlapped with each other to form a closed state of the shutter, and an inclined surface is formed on each end face so as to easily enter the door pocket sequentially.

[Problems to be solved by the invention]

According to such prior art, since the continuous shutters are connected to each other only by the connecting tool provided on the upper and lower sides or one of them, as shown in the figure, the shutters located inside the overlapping doors of the shutters are indicated by arrows from the outside. When a force is applied by wind or human power as described above, there is a problem that the vertical frame of the shutter is deflected and the connecting tool is disengaged, or the shutter is bulged inward. In severe cases, the shutter is disengaged.

[Means for Solving the Problems] Therefore, in the present invention, a locking shaft is slidably attached to a board, and the board is connected by attaching a connector to both or one of the upper frame and the lower frame of the shutter. It is characterized by being fixed to the end of the handle of the linked shutter.

[Action]

According to the above configuration, when the shutter is closed, the tip of the locking shaft is positioned immediately near the indoor side surface of the joint of the frame to which the continuous shutter is connected, thereby preventing the shutter from bending due to external force on the shutter. Can be.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a main part of an embodiment of the present invention in a state where a locking shaft is protruded, FIG. 2 is a front view, FIG. 3 is a side view, and FIG. FIG. 5 is a side view, in which 1 is a substrate, 2 is a support shaft attached to the substrate 1, and 3 is a locking shaft, which is axially movable on the support shaft 2 and is pivotable. It is fitted as possible via the support 3a. The locking shaft 3 is disposed such that its tip can protrude from one end of the support shaft 2.

Reference numeral 4 denotes a spring locked between the support shaft 2 and the lock shaft 3. The lock shaft 3 always projects forward (in a horizontal state) in the drawing, and its tip is formed by the support shaft 2. It is biased so as to protrude from one end, and is not always necessary, and may be provided as needed.

In this manner, the slip-off preventing device is constituted, and the board 1 of the slip-off preventing device is attached to the end of the handle 6 of the shutter 5 as shown in FIG.

According to the detachment prevention device configured as described above, when the shutter is closed, the front end of the locking shaft 3 is positioned immediately adjacent to the indoor side surface of the joint portion of the frame to which the continuous shutter is connected as shown in FIG. Let it.

With this configuration, when a force is applied to the shutter from outside by wind force or human power, the shutter that is going to be bent cannot be bent by the inner frame contacting the locking shaft 3. It does not break the connecting parts attached to the door, nor does the shutter come off.

Next, when closing the shutter, the locking shaft 3 is rotated upward and pulled in the direction of arrow A in FIG.
4 and 5 are fitted as shown in FIGS. 4 and 5, and the locking shaft 3 is housed in the upper part of the handle 6 so as not to hinder the storage in the door pocket.

In the above embodiment, the locking shaft 3 is rotatably fitted to the support shaft 2 via the support portion 3a. However, the locking shaft 3 is not necessarily rotatable, but is slidably fitted. There may only be.

[Effect of the invention]

According to the present invention described in detail above, the locking shaft is slidably attached to the board, and the board is fixed to the end of the handle of the connected shutter, so that when the shutter is closed, the continuous shutter is closed. It prevents bending of the shutter frame due to external force, and as a result, has the effect of eliminating the destruction of the connecting device and preventing the shutter from coming off.

In addition, when the shutter is closed, it is stored in the upper part of the handle, so that it has an effect of not obstructing the storage in the door pocket.
