Technical Field
The present invention relates to a tempered glass door, in particular, to a double locking device for a tempered glass door which can be stably used by being constructed such that it is impossible to release the locking of the door from a locking portion located at the inside of the room till the locking of the door has been released by a key cylinder, if the locking of the door has been set by the key cylinder located at the outside of the room and mounted at one side of the tempered glass door, when a handle of the locking portion located at the inside of the room and mounted at the other side of the tempered glass door has been pulled. In general, as shown in FIG. 1 , a locking device mounted at a door for entering and leaving a room is comprised of a supporting member 10 including a supporting plate 11 bent oppositely to receive one end of the door D and formed with an elongated opening 12 passing through the inside thereof in the longitudinal direction, and indoor and outdoor operation portions 20, 30 provided with actuating rods 22, 32 respectively operated to move in and out by the operation of an actuating lever 21 and the key cylinder 31 at both sides of the supporting member 10, so that the locking of the door can be set or released by moving the actuating rods 22, 32 in and out by the operation of the actuating lever 21 and the key cylinder 31 of the indoor and outdoor operating portions 20, 30 to thereby make the actuating rods 22, 32 be engaged with or released from engaging grooves Fa, Fb of a door frame F.
However, according to the conventional locking device configured as such, while it can be used by setting or releasing the locking of the door at a state when the indoor and outdoor operating portions, which are of the same structure and provided with the actuating lever and the key cylinder, are formed respectively at the inside and outside of the door, there has been caused a problem that it cannot set or release the locking of the door by one touch operation at the inside or outside of the room.
To solve the above problem of the conventional art, a locking device for a tempered glass door has been disclosed in Korea Patent Laid-Open Publication No. 2003- 61277 by the applicant of this application.
As shown in FIG 2, the prior published locking device for the tempered glass door is formed with a door locking means 100 configured to carry out the locking of the door by moving a locking portion 125 in and out by means of any one of the indoor and outdoor locking members 120, 130 mounted respectively at both sides of a supporting member 110, at a state that the locking portion 125 is mounted inside of the indoor locking member 120 operated by a hand from the indoor for engaging with a door frame F, after securing the indoor and outdoor locking members at both sides of the supporting member 110 engaged to the tempered glass door D with contacting at both surfaces by inserting it from one side of the door. Further, the door locking means 100 comprises, a supporting member 110 formed by bending a metal plate and engaged with the door by contacting at both surfaces after slide inserted from one side of the door; an indoor locking member 120 constructed to move the locking portion 125 in and out by the operation of the lever 170 with the locking portion being received in one surface of the supporting member 110; an outdoor locking member 130 mounted and engaged with the supporting member 110 at the position corresponding to the indoor locking member 120 and constructed to move the locking portion 125 in and out by using the key cylinder from the outside; and a connecting means 140 constructed to connect both dismal ends of the indoor and outdoor locking members 120, 130 respectively to thereby move the locking portion 125 in and out together with the operation of any one of the indoor and outdoor locking members 120, 130.
However, in the prior published locking device for the tempered glass door, while it is advantageous that it is easy to set or release the locking of the door with the inward and outward movement of the locking portion, when any one of the locking members connected by means of the connecting means is operated, there have been caused problems that it is not only possible to release the locking of the door by inserting a wire attached with a rubber or a robotic hand from the outside of the door between the door frame, but the reliability of the product is also reduced because the several indoor substances are exposed to the danger of robbery if the locking of the door is to be released.
Also, there is a problem that an assembly process is complicated, because it is necessary to locate the supporting member and the locking members on an identical line and assemble them again, when the free movements of the indoor and outdoor locking members are produced to cause discordance with the supporting member, as the indoor and outdoor locking members are close adhered to the supporting member and are engaged with each other to receive a side of the door.
