Description

Lock for frameless window

Technical field

The present invention relates to a kind of lock, particularly a kind of lock that is used to not have the frame window.

Background technology

No frame mosquito partition window is a kind of new product in recent years, the characteristics of existing sliding sash before combining, and the window lock of frame free type that a kind of on this basis novel being used to do not have frame mosquito partition window has come out.

Existing in the past sliding sash lockset has three kinds by opening ways: pressing of revolving crescent lock, button type locked and shuttle-type lock.These three kinds of deficiencies that are latched in have: 1, use crescent lock to exist inside and outside two sash that mobile gap is arranged, and the back is latched in easy failure phenomenon for two kinds; 2, the opening and closing of three kinds of locks with window and close window action and separate, two actions are arranged windowing and close in the window process: one is the action of unblanking or lock, and another one is the action of mobile sashes; 3, three kinds of locks all have only a kind of opening ways; 4, be not suitable for not having frame mosquito partition window.

In conjunction with the not enough of slide window lock existence in the past and their characteristics, and according to the characteristics of no frame mosquito partition window, the characteristics of window lock of frame free type have: 1, the switch of the switch of sash and lock fully combines, the pinning of sash lock and the process of unblanking be the process of a switch sash just, and action does not realize in two steps; 2, interior outer leaf pins fully, and does not have the gap of move left and right, thereby improves anti-theft effect; 3, two kinds of opening ways are arranged: a kind of use knob is opened, another kind of directly moving up and down of control dead bolt; 4, because simple for structure and smooth thereby good looking appearance and be streamlined is installed in sash, good visual effect as a decoration.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of two theftproof locks of opening function of realization that can be installed on the no frame mosquito partition window.This lock comprises lock, and the snap close that is installed in the dead bolt on the lock and cooperates with dead bolt comprises that also the back side knob that is contained in lock promotes moving up and down of dead bolt by pressing knob, thereby realizes unlocking function.This lock of the present invention like this is except that having parts such as dead bolt that general lockset possesses and snap close, simultaneously also fully in conjunction with principles such as kinesiology and the antitheft theories of sliding sash, increased knob in the present invention and realized that two functions of opening (promptly can realize unblanking by direct control dead bolt, can realize unblanking by pinning knob again), in addition in design process to having increased the moulding that meets kinesiology in lock and the dead bolt, make the opening and closing of this lockset be more suitable for people's operating habit.

The specific embodiment

Window lock of frame free type is formed by lock 1, dead bolt 2, knob 3, snap close 4, briquetting 5, latch bolt spring 6 with by seven component such as torsion springs 7 shown in figure two.Wherein dead bolt 2, knob 3, briquetting 5, latch bolt spring 6 and be assembled on the lock 1 by connector by five component such as torsion springs 7, thus constitute a whole lock mechanism, reach the pinning effect thereby cooperate with snap close 4 by dead bolt 2.

On lock 1, be distributed with two orthogonal grooves.Dead bolt 2 is by packing into (can find out from figure one, a front view) in the groove positive on the lock 1, and dead bolt 2 can freely move up and down in this groove.Latch bolt spring 6 is equipped with in junction at dead bolt 2 and lock 1, and dead bolt 2 is also compressing latch bolt spring 6 when freely moving up and down in this groove, and the spring force by latch bolt spring 6 automatically resets dead bolt 2.Briquetting 5 is screwed on lock 1, thereby pushes down latch bolt spring 6 and avoid ejecting guide pillar owing to the compression of latch bolt spring 6, does not have the effect that acts freely.

Knob 3 is contained in the reverse groove of lock 1 (can find out from figure one, b back elevation), and the back side guide groove of lock 1 can limit the degree of freedom of knob 3 move left and right and rotation, and only to move up and down.Be placed on by torsion spring 7 in the hole of knob 3, when pinning knob 3 with hand and down move, also compressing by torsion spring 7 simultaneously, when openhanded when opening knob 3 under by the effect of torsion spring 7 power self-return.One inclined-plane is arranged on knob 3, and this inclined-plane cooperates with dead bolt 2.

This window lock of frame free type has two kinds of opening ways: thus first kind of mode is to move up and down and realize unblanking and locking function by pushing down dead bolt 2; The second way is down moved and is realized unblanking and locking function by pinning knob 3.
