DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 1 to 6, the safety device of the present invention is installed between the wall 10 and the scrolling door 20, and connected with a clutch 30. The safety device comprises a frame 1, a lock 2 and a control member 3. The frame 1 includes a first groove 11 and two second
: grooves 12 which are independently located on two sides of the first groove : 11. The first groove 11 accommodates the scrolling door 20 therein. The - two second grooves 12 are respectively located at an indoor position and an = outdoor position. The lock 2 is located on outside of the second groove 12 - that is located at the outdoor position. The lock 2 is connected to outside of o the frame 1. A first cable 21 has the first end thereof connected to the lock 2, and the second of the first cable 21 is connected to the clutch 30. The first c cable 21 is located in the second groove 12 that is located at the indoor - position. The lock 2 controls the clutch 30 to activate the manual operation mode or the electrical operation mode.
The control member 3 is connected to inside of the frame 1 and has a housing 31, a transmission unit 32 and a control unit 33. The housing 31 includes the first side thereof connected to the frame 1, and a room 311 is defined in the housing 31. An opening 312 is defined through the second side of the housing 31 and communicates with the room 311. The control unit 33 includes a push button 331 and a press button 332, wherein the push button 331 is pivotably located at the opening 312, and partially located in the room 311 and partially located beyond the opening 312. Specially, the push button 331 is pivotably connected to the housing 31 by extending a pivot 37 through a tubular part 38 (Fig. 4) of the push button 331 to be
. connected to the housing 31. The press button 332 is located on the top of the housing 31. 0
The transmission unit 32 is pivotably located in the room 311 and ® located below the press button 332. The transmission unit 32 includes a first ” part 321 and a second part 322. The mediate portion of the first part 321 is » pivotably connected to the mediate portion of the second part 322. A link 4 i is pivotably connected between the first end of the first part 321 and the = push button 331. A block 5 protrudes from the first part 321 and is located between the first end of the first part 321 and the first end of the second part 322.

Specifically, the push button 331 includes another pivot 39, and one end of the link 4 is pivotably connected to the pivot 39. A first torsion spring 9 is mounted to the pivot 39 and located between the link 4 and the push button 331. The first torsion spring 9 brings the push button 331 backward when the push button 331is released. A second rod 41 extends from the inside of the room 311 and the press button 332 is mounted to the second rod 41. The press button 332 includes a press portion 341 and a
: : hooking portion 342, wherein the press portion 341 is exposed beyond the = housing 31. -
The first part 321 includes a push portion 7 on the first end and a = restriction portion 8 on the second end thereof. The block 5 and the link 4 ’ are connected to the push portion 7. A recessed area 81 is defined in one side of the restriction portion 8 and faces a first rod 34 extending from an o inside of the room 311. The first rod 34 contacts the recessed area 81 when o the push button 331 is not pushed. The second part 322 includes a 5 protrusion 35 on the first end thereof and a lower portion 36 on the second end thereof. The notch 333 is defined in the lower portion 36 which pulls the second cable 6 to control the clutch 30. “As shown in Figs. 7 to 10, when the push button 331 is pushed toward the room 311, the first part 321 is pivoted by the link 4, and the block 5 pushes the protrusion 35 of the first end of the second part 322 and the protrusion 35 is stopped by the first rod 34, and the lower portion 36 of the second part 322 drives the second cable 6 to activate the clutch 30 so that the scrolling door 20 is able to be opened manually. Specifically, when the push button 331 is pushed toward the room 311, the link 4 pivots the first part 321, and the recessed area 81 is moved away from the first rod 34, so that the block 5 and the push portion 7 pivots the second part 322. The hooking portion 342 hooks to an engaging portion 343 of the push button
