As shown in
Thus, the aforementioned wrong push-press mode is likely to cause the exit 100 in a stuck case, and resulting in inconvenience and danger of escape.
In view of this, it is important to provide an exit lock assembly to avoid the above stuck case.
An objective of the present invention is to provide an exit lock assembly that the user can easy open when it are energized.
To achieve the aforesaid objective, a first embodiment of the exit lock assembly comprises a base, two doorstops, two first links, two second links, two solenoid valves and a cover. The base has a central area and two side areas disposed at two sides of the central area, the central area has two first axes and two second axes opposite to each other, and the side area has two third axes. The two doorstops are disposed at the two first axes of the central area, and have a first end and a second end respectively. The two first links are disposed at the two second axes of the central area, and have a third end for holding the second end of the doorstop respectively. The two second links are disposed at the two third axes of the side areas. The two second links have a fourth end and a fifth end respectively, and the fourth end is adapted to hold the third end of the first links in a holding status. The two solenoid valves are disposed at an outer edge of the two side areas, each the two solenoid valves has a plug respectively, and the plug is adapted to join the fifth end of the second link. The cover is adapted to combine with the base to form a receiving space for receiving the two doorstops, the two first links, the two second links and the two solenoid valves. When the solenoid valves are energized, the two plugs of the two solenoid valves move along the direction opposite the central area and drive the two fifth ends of the two second links, the two fourth ends of the two second links thus separate from the third ends of the first links, and the second end of the doorstop moves down.
To achieve the aforesaid objective, a second embodiment of the exit lock assembly comprises a base, two doorstops, two first links, two solenoid valves and a cover. The base has a central area and two side areas disposed at two sides of the central area, the central area has two first axes and two second axes opposite to each othe. The two doorstops are disposed at the two first axes of the central area, and has a first end and a second end respectively. The two first links are disposed at the two second axes of the central area, each the first links has a third end and a projection, and the third end is adapted to hold the second end of the doorstop respectively. The two solenoid valves are disposed at the two side areas, each the two solenoid valves has a plug respectively, and the plug hold the projection of the first link in a holding status. The cover is adapted to combine with the base to form a receiving space for receiving the two doorstops, the two first links and the two solenoid valves. When the solenoid valves are energized, the two plugs of the two solenoid valves move along the direction opposite the central area so as the projection of the two first links break away from the holding status, and the second end of the doorstop moves down.
The detailed technology and preferred embodiments implemented for the subject invention are described in the following paragraphs accompanying the appended drawings for people skilled in this field to well appreciate the features of the claimed invention.
As shown in
With reference to
The two doorstops 220 are disposed at the two first axes 212 of the central area 210a, and have a first end 222 and a second end 224 respectively. The two first links 230 are disposed at the two second axes 214 of the central area 210a, and have a third end 232 for holding the two second ends 224 of the two doorstops 220 respectively.
Further, with reference to
The two solenoid valves 250 are disposed at an outer edge of the two side areas 210b, each the two solenoid valves 250 has a plug 252 respectively, and the plug 252 is adapted to join the fifth end 244 of the second link 240.
Therefore, the cover 260 is adapted to combine with the base 210 to form a receiving space for receiving the two doorstops 220, the two first links 230, the two second links 240 and the two solenoid valves 250.
As a result, when the solenoid valves 250 are not energized, via the specific arrangement of the doorstops 220, the first links 230, the second links 240 and the solenoid valves 250, the fourth end 242 is adapted to hold the third end 232 of the first link 230 to form a holding status so as the doorstops 220 are in a close status.

As shown in
In addition, a first roller 224a and a second roller 262a are disposed on the second end 222 of the doorstop 220 and the third end 232 of the first link 230 respectively, so as to reduce the friction between the second end 222 of the doorstop 220 and the third end 232 of the first link 230 while moving and effectively prevent the occurrence of stuck situations.
Preferably, as shown in the first embodiment, the first link 230 has an arc-like shape. When the third end 232 of the first link 230 rotates along the second axis 214 to produce a displacement, the second end 224 of the doorstop 220 could rotate along the first axis 212 and move along the arc-like shape while the second end 224 of the doorstop 220 is not in the holding status, and thus the doorstop opened.
As shown in
With reference to
The two doorstops 320 are disposed at the two first axes 312 of the central area 310a, and have a first end 322 and a second end 324 respectively.
The two first links 330 are disposed at the two second axes 314 of the central area 210a, each the first links 330 has a third end 332 and a projection 334, and the third end 332 is adapted to hold the second end 324 of the doorstop 320 respectively. The two solenoid valves 340 are disposed at the two side areas 310b, each the two solenoid valves 340 has a plug 342 respectively, and the plug 342 hold the projection 334 of the first link 330 in a holding status.
Therefore, the cover 350 is adapted to combine with the base 310 to form a receiving space for receiving the two doorstops 320, the two first links 330 and the two solenoid valves 340.
As a result, when the solenoid valves 340 are not energized, via the specific arrangement of the doorstops 320, the first links 330 and the solenoid valves 340, the plug 342 is adapted to hold projection 334 of the first link 330 to form a holding status so as the doorstops 320 are in a close status.
