DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.

(10) With reference to FIGS. 1-3, a safe opening system according to a preferred embodiment of the present invention being is mounted on an automobile 10.

(11) The automobile 10 comprises a body 11, at least one automobile door 12, and a driving device 13.

(12) The body 11 includes at least one peripheral frame 111, each of the at least one peripheral frame 111 has a locker 112 fixed thereon, and the locker 112 has a fixing groove 1121 formed thereon.

(13) Each of the at least one automobile door 12 includes a front fringe 121 and a rear fringe 122 opposite to the front fringe 121 and facing a decoration plate 123 of the body 11, and the rear fringe 122 has an accommodation chamber 1221 in which a slot 1222 and a locking tongue 1223 are arranged, wherein the decoration plate 123 has a door bar 1231 disposed thereon and has an orifice 1232 defined adjacent to the rear fringe 122, such that the automobile door 12 is actuated to rotate along the body 11 so as to be opened or closed.

(14) The driving device 13 includes an actuation sheet 131 and a spring 132, the actuation sheet 131 has a hook 1311 extending from a flat surface thereof, a connection stem 1312 perpendicular to the actuation sheet 131, a tab 1313 opposite to the hook 1311, and a rotary shaft 1314 inserted into the tab 1313. The spring 132 is fitted on the rotary shaft 1314, and the driving device 13 is accommodated in the accommodation chamber 1221, the actuation plate 131 is housed in the slot 1222 of each automobile door 12, wherein the connection stem 1312 is inserted into each automobile door 12 and a distal end of the connection stem 1312 is inserted through and partially extends out of the orifice 1232.

(15) In use, after each automobile door 12 closes each peripheral frame 111 of the body 11, the front fringe 121 and the rear fringe 122 contact with each peripheral frame 111 so that the locker 112 of the body 11 is located in the accommodation chamber 1221 of each automobile door 12, the locking tongue 1223 inserts to the locker 112, the hook 1311 of the driving device 13 retains with the fixing groove 1121 of the locker 112. Referring to FIG. 4, when a driver or a passenger pulls the door bar 1231 of the decoration plate 123 and pushes each automobile door 12 outward, the hook 1311 of the driving device 13 retains with the fixing groove 1121 of the locker 112 so that a gap is defined between the body 11 and each automobile door 12 and is not expanded. As shown in FIG. 5, the driver or the passenger has to turn close to the orifice 1232 of the rear fringe 122 and to upward pull/downward press the distal end of the connection stem 1312 so that the connection stem 1312 drives the actuation sheet 131 in the slot 1222, and the rotary shaft 1314 rotates to actuate the hook 1311 to move downward/upward. As illustrated in FIG. 6, when the hook 1311 of the driving device 13 does not retain with the fixing groove 1121 of the locker 112, the body 11 and each automobile door 12 is opened completely. With reference to FIGS. 7 and 8, after the connection stem 131 is not pulled upward/pressed downward, the spring 132 pushes the actuation plate 131 to move back to an original position.

(16) When the driver/the passenger pulls a door handle outside each automobile door, the door handle drives the connection lever 1312 to urge the hook 1311 to move downward/upward, thus opening each automobile door 12 outdoors in a first operation step.

(17) The driving device is configured to open each automobile door in two operation steps for the driver/passenger, after the driver/passenger turns close to each automobile door, hence he/she notices whether there are automobiles/motorcycles/bicycles/passengers behind each automobile door. Preferably, the driving device is operated mechanically and does not contain any electronic parts so as to reduce failure rate. In case the automobile break down, out of power of battery or is turned off, supplying the power to the driving device 13 is not required, and the driving device 13 operates smoothly in the two operation steps so as to open each automobile door safely. In addition, the driving device is simplified so as to reduce fabrication and maintenance costs.

(18) Accordingly, the safe opening system of the present invention has following advantages:

(19) 1. The driver/passenger has to turn close to each automobile door so as to pull/press the distal end of the connection stem 1312, and the connection stem 1312 drives the actuation plate 131 so that the rotary shaft 1314 rotates to actuate the hook 1311 to move downward/upward, and each automobile door 12 of the body 11 is opened completely, such that each automobile door 12 is opened in the two operation steps.

(20) 2. The driver/passenger has to turn close to each automobile door so as to upward pull/downward press the distal end of the connection stem, hence he/she notices whether there are the automobiles/motorcycles/bicycles/passengers behind each automobile door.

(21) 3. The driving device 13 is operated mechanically and does not contain any electronic parts so as to reduce the failure rate. In case the automobile break down, out of power of battery or is turned off, supplying the power to the driving device 13 is not required, and the driving device 13 operates smoothly in the two operation steps.

(22) 4. The driving device 13 is operated mechanically and is simplified so as to reduce the fabrication and maintenance costs.

(23) 5. The driving device 13 is operated mechanically and is simplified so as to reduce the failure rate.

(24) While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
