Abstract
Description
- The present invention relates to a lock especially for a window or sliding door lock that drives two locking plates in opposite directions to lock windows or sliding doors.
- A conventional lock for windows or sliding doors shown ( Figs. 6 and 7) generally includes a
handle 50 with aspindle 51 that extends through a rosette, adriving assembly 60 with adriving member 70 received therein, and alocking rail 80 which is driven by thedriving member 70 to move up and down between the lock position and the open position. Thedriving assembly 60 includes two lugs on two ends, thereof, and each lug is connected to thelocking rail 80 by rivets, which extend through twoslots 83 in thelocking rail 80. Thedriving assembly 60 is composed of twoparts member 70 is received. Thespindle 51 extends and engages with apolygonal hole 71 in thedriving member 70 and a plurality ofteeth 72 are defined on the outside of the drivingmember 70. Arack plate 81 is fixed to thelocking rail 80 and theteeth 82 of therack plate 81 are engaged with theteeth 72 of thedriving member 70, such that when thehandle 50 is pivoted, thedriving member 70 is rotated by thespindle 51 to drive therack plate 81, so that thelocking rail 80 is moved a distance the same as theslots 83 between the lock position and the open position. - However, the
rack plate 81 and thelocking rail 80 are connected at two points, so that therack plate 81 shakes when driven by thedriving member 70. The unstable engagement between thelocking rail 80 and therack plate 81 might cause movement of thelocking rail 80. Furthermore, thelocking rail 80 is an elongated plate, which is not convenient for packing and transportation. - The present invention intends to provide a window or sliding door lock, wherein two rack pieces are moved simultaneously in opposite directions, so as to move two locking plates between lock position and open position.
- The present invention relates to a window or sliding door lock that comprises a handle with a spindle extending through a rosette, which is connected to a driving assembly. A driving member is received in a rotating action in the driving assembly. The spindle extends through an eccentric polygonal hole in the driving member that rotates as the handle and spindle are turned. The driving member has male teeth defined along its side, while two rack pieces are movably connected to the driving assembly and each rack piece has a set of female teeth, which are complementary to the male teeth on the driving member. The complementary teeth of one of the two rack pieces are engaged with the male teeth of the driving member. The two rack pieces each have a toothed surface on a different side of the racks and these two respective toothed surfaces face each other in the assembly. Two pinion gears are located between the two rack pieces and are engaged in rotation with the two respective toothed surfaces. The two rack pieces move in opposite directions when the driving member rotates and drives the female teeth of one of the two rack pieces. Two locking plates are located on two ends of the driving assembly and are connected respectively to the two rack pieces.
- The primary objective of the present invention is to provide a lock of windows or sliding doors, in which the lock includes two locking plates that are driven by two rack pieces in opposite directions.
- The present invention will become more obvious from the following description when taken into account the accompanying drawings, which show (for illustration purposes only) a preferred embodiment in accordance with the present invention.
-
- Fig. 1 is an exploded view to show the lock of the present invention including a handle and a driving assembly and a window frame;
- Fig. 2 is an exploded view to show the parts of the lock of the present invention;
- Fig. 3 shows that the two locking plates are in lock position;
- Fig. 4 shows that the two locking plates are in open position;
- Fig. 5 shows that the driving assembly is connected to the window frame by an inclined, pointed set screw extending through the driving assembly;
- Fig. 6 is an exploded view to show a conventional window lock, and
- Fig. 7 is a cross sectional view to show the movement of the locking rail of the conventional window lock.
- Referring to Figs. 1 to 3, the lock of the present invention comprises a
handle 10 connected to aspindle 12, which extends through arosette 11. Adriving assembly 20 is attached to a door or awindow frame 40. Thedriving assembly 20 is composed of two main-housing parts housing 21 a andsmaller protrusion 24 create a U-shapedrecessed space 25, located on one side of the inner surface of main-housing part 21a andpart 21b. The main-housing part 21a includes two holes and the other main-housing part 21b has twoconnection tubes 22, each of which has a threaded hole (not shown). The two main-housing parts screws 13 that extend through the two holes on each side of main-housing part 21a and are connected and fastened to theconnection tubes 22 on the other main-housing part 21b. Adriving member 26 is engaged in rotation within a groove in themiddle protrusion 23 on the main-housing part 21a in thedriving assembly 20, while thespindle 12 extends through thehole 211 defined through themiddle protrusion 23 and through the eccentricpolygonal hole 261 in the driving member 26 (thedriving member 26 hasmale teeth 262 defined along its outer edge). - The two
rack pieces 27 each include a U-shaped section on the rack, which hasfemale teeth 271 defined therein. These U-shaped sections movably engage within the U-shapedspaces 25 in themain housing 21a /21 b. Thefemale teeth 271 of one of the tworack pieces 27 engage with themale teeth 262 of thedriving member 26. The tworack pieces 27 also each have atoothed surface 272 on the side and the tworespective toothed surfaces 272 face each other. Twopinion gears 28 are located between the tworack pieces 27 and are engaged in rotation with the tworespective toothed surfaces 272. Therefore, the tworack pieces 27 move in opposite directions when the drivingmember 26 drives thefemale teeth 271 of one of the tworack pieces 27. - Two
locking plates 30 are located on two ends of thedriving assembly 20 and are respectively connected to the tworack pieces 27. Each of the tworack pieces 27 has astud 273 on one of the two ends, thereof, and the twolocking plates 30 each have ahole 31 with which one of the twostuds 273 is engaged. - As shown in Fig. 3, when the
handle 10 is in its lock position, the tworack pieces 27 are moved away from each other in two opposite directions so that the window or the door is locked. As shown in Fig. 4, when thehandle 10 is pivoted, thelocking plates 30 are moved toward each other and the window or the door is in open position. - As shown in Fig. 5, the
driving assembly 20 includes aninclined hole 212 and aset screw 29. Theset screw 29 is engaged by means of a threaded passage within theinclined hole 212, so that thedriving assembly 20 is fastened to thewindow frame 40. The main purpose of theset screw 29 is to ensure that thedriving assembly 20 is fixed on the profile, orwindow frame 40. - The two
locking plates 30 are driven by the tworack pieces 27 so that each of thelocking plates 30 moves stably. The tworack pieces 27 are moved by the twogears 28, which are engaged within thetoothed surfaces 272, so that the tworack pieces 27 do not shake while moving. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
