Description

The present invention relates to a shutter louver guide structure, and more particularly to a louver guide structure that can be applied to an electric door shutter and a window shutter and has a guide function when the louver is closed.

When closing a conventional shutter (such as a door shutter or a window shutter), a plurality of louvers are provided at intervals in order to increase the amount of ventilation in the space, and air is convected using these gaps.

However, when closing the shutter louver, it is affected by the frictional force at the place where it is connected to the linkage and the crankshaft, so it is difficult for all the louvers to maintain an accurate return angle. However, in order to ensure that all louvers are closed in a consistent manner, it is necessary to wind up all the shutters and then lower them again to fold them down. Cannot be secured at the same rotation angle.

The purpose of the present invention is to provide a guidance function for the window shutter, so that the closing angle of all louvers is accurate, and it is not necessary to wind up all the window shutters, and each louver is closed evenly and securely. A shutter louver guide structure that can be used and operated more conveniently.

To achieve the above object, the shutter louver guide structure of the present invention includes a winding device, an interlocking mechanism, and a guide block. The hoisting device includes a door body and a frame, and the door body is provided with a plurality of louvers.

FIG. 6 is a three-dimensional view of a guide block according to another embodiment of the present invention.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Please refer to FIGS. As can be seen from the figure, the shutter louver guide structure of the present invention includes a winding device 1, two interlocking mechanisms 2, a plurality of guide blocks 3, and two drive devices 4.

Among them, the hoisting device 1 includes a door body 11, a frame 12 connected to the door body 11, and two rails 13 that pivot on the door body 11. The door body 11 has a plurality of louvers 111.

The interlocking mechanism 2 is provided on both sides of the door body 11 provided in the winding device 1. Each interlocking mechanism 2 includes a linkage group 21, a second linkage group 22, and a plurality of crankshafts 23. One side of the crankshaft 23 is pivotally connected to the first linkage group 21 and then connected to the louver 111. The other side of the crankshaft 23 is connected to the second linkage set 22, and a contact end 24 is provided at the end of the crankshaft 23, and the contact end 24 is located outside the second linkage set 22. In the present embodiment, all or a part of the crankshaft 23 is provided at the contact end 24, and the error when returning the respective louvers 111 can be adjusted more accurately. The abutting ends 24 of the interlocking mechanism 2 are installed at intervals, and are attached to both sides of the door body 11 of the hoisting device 1 by a cross-attaching method.

A plurality of guide blocks 3 are arranged on both sides of the frame 12 of the winding device 1. Each guide block 3 has an inclined guide slope 31, the guide slope 31 forms a first end 311 at the bottom near the guide block 3, and a second end 312 near the top of the guide block 3. Form. The guide block 3 is provided inside the frame 12 of the winding device 1, and the contact end 24 is in contact with the guide slope 31 of the guide block 3.

The drive device 4 includes a fixed base 41, a shaft control tool 42, and a guide set 43. The fixed base 41 is provided on the frame 12 of the hoisting device 1, and the axis controller 42 is pivotally connected to the first linkage group 21, the second linkage group 22 of the interlock mechanism 2, and the louver 111 above the door body 11, The end of the shaft control tool 42 is brought into contact with the fixed base 41. A guide set 43 is provided above the fixed base 41. The door 11 of the hoisting device 1 is driven by a drive motor (not shown) to move the first linkage group 21 of the interlock mechanism 2 upward, and the second linkage group 22 is brought close to the first linkage group 21. To complete the winding of the door body 11.

3 and 5, reference is made to the open and closed state of the louver 111 provided in the door body 11 of the present invention. When the door body 11 of the hoisting device 1 is lowered, the shaft control tool 42 is applied to the introduction slope 411 of the fixed base 41, and the shaft control tool 42 controls and operates the interlocking mechanism 2, thereby opening or closing the plurality of louvers 111. Closing operation is possible.

Continuing to refer to FIG. 3 and FIGS. The figure shows an embodiment in which a plurality of louvers 111 provided in the winding device 1 are switched from an open state to a closed state. The shaft control tool 42 of the driving device 4 is applied to the introduction slope 411 of the fixed base 41, and the first linkage group 21 and the second linkage group 22 of the interlocking mechanism 2 form an expanded state, and the plurality of louvers 111 are expanded. Linked to the state. Therefore, when the louver 111 is closed, the first linkage 21 of the interlocking mechanism 2 is moved a slight stroke upward, and the second linkage 22 is moved by gravity to cause the guide slope 31 of the guide block 3 and the interlocking mechanism 2 to move. The contact end 24 is moved from the first end 311 to the second end 312 of the guide slope 31 of the guide block 3 with an acting force that contacts the contact end 24, and the second linkage 22 is moved to the first link 31. The louver 111 is brought close to the pair 21 and further closed by returning the plurality of louvers 111 to their original positions.

Continuing to refer to FIGS. 8 and 9, an embodiment diagram of the guide blocks 3,5. As shown in FIG. 9, the guide block 3 extends to both upper and lower ends to form a first fastening portion 32 and a second fastening portion 33, and the first fastening portion 32 of the guide block 3 is the second of the other guide block 3. It is connected to the fastening part 33. As shown in FIG. 9, the guide block 5 is integrally formed, and a plurality of projections 51 are provided at intervals so that the guide slope 511 formed on the side surface of each projection 51 is the above-described guide function. Is generated.

Therefore, the main technique of the present invention is to guide the contact end 24 using the guide slope 31 and when the first linkage group 21 and the second linkage group 22 of the interlocking mechanism 2 move relative to each other, The linkage group 21 is directed upward by the driving of the motor, the second linkage group 22 is subjected to gravity action, and the guide slope 31 and the abutting end 24 are brought into contact with each other to generate a thrust, whereby the second linkage group 21 22 is drawn to the first linkage group 21. This overcomes the generation of excessive frictional force by the known technique and the problem that the known louver cannot be recovered successfully. Furthermore, according to the present invention, it is possible to reliably return all the louvers 111 with only a slight stroke. The problem that cannot be realized unless it is completely wound up as in the prior art can be solved, and the convenience of operation of the present invention can be greatly improved.
