Specific embodiment
It should be appreciated that this utility model is not limited to before describing any embodiment of the present utility model in detail
Middle elaboration described below or the details of the structure of part shown in drawings described below and arrangement.This utility model can have it
Its embodiment and being practiced or carried out in every way.
Fig. 1 shows including the door 10 according to children's safety handle of the present utility model.Noticed as below, this
Utility model can be applied to the substantially any machine that handle is optionally coupled and separated with the concentric heart axle supporting this handle
Structure, but in order to be illustrated, show this utility model in door handle application, but this application readily becomes cupboard
Cabinet.Door 10 pivots in doorframe between open position and closing.Blocking mechanism 50 and door handle 60 are provided with this door 10.
Blocking mechanism 50 is configured for mount on door 10, and includes latch members and the heart axle with square cross section
Or pivot member.Term " locking " and its modification are intended to cover and by the door temporary blocking of closing or can be capable of the door lock that will close
The mechanism lived.In this respect, in this written description and claims, " locking " and its modification should be construed to " locking
(breech lock) or locking ".Latch members can move between extended position and retracted position with respect to door 10.In extended position, close
The free end of lock construction element stretches out from the free edge of door 10.Latch members are biased into extended position.In retracted position, locking structure
Part overcomes biasing force to move axially in door 10.In retracted position, the free end of latch members will not substantially extend over door
10 free edge (if stretching out).When door 10 moves to closed position, this latch members is clashed in response to free end
Doorframe and axial deflection are to retracted position.When the incorporating section in latch members with doorframe is to punctual, this biasing force makes latch members
Move axially to extended position.
When positioned at extended position and when being bonded in incorporating section, door 10 is maintained in its closed position by latch members, and phase
Door 10 is releasedly fixed by the wall such as installing doorframe for adjacent structure.
Breech lock shown in Fig. 2 (catch) assembly 20, this latch assembly 20 is arranged between door handle 60 and door 10, wherein
Square sectional heart axle 15 passes through this latch assembly.Latch assembly 20 includes the security-latch slidably and displaceably installed
21, this security-latch 21 includes the elongated slot 22 extending in the shift direction, and this elongated slot 22 has locking section 23 He
Adjacent enlarged 24, the side length of this locking section 23 is corresponding with the square cross section of square shaft, this adjacent expansion
Part 24 has minimum diameter corresponding with the diagonal of square cross-sectional shape.Because slit 22 is included with square shaft
The side length of square cross section and the section of corresponding width and have corresponding with the diagonal of this square cross section
Minimum diameter adjacent enlarged 24, so only when its square shaft 15 be located at extension 24 region in when operation handlebar
Handss 60 could rotate.Thus, security-latch 22 is pushed to wherein locking section 23 and square shaft 15 by resilient spring device 25
The position of be aligned, thus preventing axle 15 from rotating, and can by user's extrusion spring device 25 simultaneously slide latch 21 and move
To the position that wherein enlarged 24 is aligned with square shaft 15, such that it is able to make this axle rotate.When handle 60 is released, door
Door handle 60 is automatically back into position of rest by the spring on handle bar latch (not shown), and this makes the lock of axle 15 and security-latch
Determine section be aligned, security-latch 21 is automatically back into latched position by spring assembly 25.
This security-latch assembly includes housing 26, and this housing 26 includes sliding rail 27 and is used for user operation button 28
Opening, security-latch 21 slides on this sliding rail 27, and this sliding rail 27 is that spring assembly 25 provides and supports.As
Shown in Fig. 3, security-latch housing 26 also includes positions and dimensions cover corresponding with existing handle standard lid 30 and fixing hole 29.Only
Only by existing handle is removed, security-latch assembly is positioned to be aligned with fixing hole, using identical screw, attaching should again
Handle is security-latch assembly to be fixed between existing handle brackets and door or cabinet it is possible to by whole security-latch assembly
20 repack any existing handle 60 of adaptation into.The additional width to adapt to security-latch assembly for the slightly longer screw may be needed
Degree.
Referring now to Fig. 4, show another embodiment of the present utility model, which provided secondary lock 40, this pair lock 40
Prevent security-latch 21 mobile, unless this pair lock 40 is released by a user.The forms of slidably breech lock 41 taken by secondary lock 40, it against
Its own spring 42 and orthogonally slide with security-latch 21, and spring loads position blocks as main lock security-latch
21 motion, this pair lock 40 can move to this pair lock by user and not stop peace by carrying out sliding motion against spring assembly 42
The position of full breech lock 21.The user of secondary lock 40 approaches the user with security-latch 21 that button 43 is located at security-latch assembly 20
The contrary side of operable button 28.When released, secondary lock 40 is spring biased and automatically return to latched position.
Referring now to Fig. 6, it illustrates another embodiment, and wherein common part has identical reference.At this
In embodiment, as the replacement of fixing hole 29, this cover lid has attachment slot 51, and this attachment slot adapts to pre-existing hole
Change in location.Lock in previous embodiment only on the window with this handle and door effectively, i.e. this handle is two
There is between individual screw a distance accurately giving.It has been determined, however, that there being a large amount of windows to have two using same type
Individual screw and the operating handle of standard square central shaft, but the distance between described screw difference.By the present embodiment
Feature, all of known difference window type all can use assembly of the present utility model.
The difference of this embodiment also resides in, release button 28 be disposed along and be formed at fixing hole 29 (or
Be attachment slot 51 in this embodiment) between the line of diameter parallel longitudinally move with respect to security-latch assembly.At it
In front embodiment, release button moves up in the side of the axis between two fixing holes 29.First and second
The width of embodiment (is grasped in order to the necessary stroke distances discharging four-square lock region from described axle by lock to a great extent
Make the minimum widith of the square shaft in handle) and the side pushing direction regulation for this release operation.
This width is all wide for perhaps eurypalynous window and doorframe, and this explanation lock will stop that window opens or at all
Cannot install.
3rd embodiment of Fig. 5 is by changing over the direction of relieving mechanism along doorframe rather than across through coming
Obtain more slim design.
This embodiment has the further advantage that, it will eliminate the needs to more than one mode-locking type or size,
Because this single embodiment is possible to for narrow doorframe much and door that is the widest and having variable screw hole distance
Frame.
Locking direction change embodiment make width narrower and make it possible to for variable screw hole away from
From.
