The locking plate of plane handle device
What the present invention relates to is the locking plate of plane handle device, and the handle of the revolution operation locking plate of above-mentioned plane handle device submerges when not using and remains in the housing.
Open the example shown in the clear 56-3494 communique as real, the locking plate in this plane handle device is to be made by iron or stainless steel, and its driven hole is shaped by the punch process punching out.
But, this plane handle device also has some shortcomings, consider from economy, the operation male member of its handle main body is made with zinc die casting or aluminium die casting, the edge sliding-contact in the driven hole that is stamped to form on the locking plate of it and irony or stainless steel, because very big difference is arranged on material hardness, so turning round repeatedly in the operating process, the scratch slot part of depth is eaten at the edge in the driven hole of locking plate side, thereby cause locking plate not move, if make the locking plate revolution limpingly by powerful drawing handle, because of be with handle body part as the excessive bending stress of the wrist effect of rod member, the operation male member will fracture at the scratch slot part.
Therefore, purpose of the present invention just provides losing of a kind of operation male member that makes it not take place handle, and has good durability, can simply and at low cost be carried out the locking plate of the plane handle device of processing simultaneously again.
In order to realize purpose of the present invention, the present invention has adopted following technical scheme, below uses the reference marks of accompanying drawing that this technical scheme is described.In the locking plate 4 of plane handle device of the present invention, the edge part 9,10 in driven hole 8 is processed into the state of bending up, make the side of operation male member and flexure plane 9a, the 10a sliding-contact of above-mentioned bore edges portion 9,10.
Locking plate 4 stretches out space, behind at housing 1 with bore edges portion 9,10, and is installed on the housing 1.This plane handle device is as Fig. 6, shown in Figure 7, when handle 2 submerges in housing 1, crooked leaf spring 27 is that the center is turned round in Fig. 7 in a clockwise direction, push handle 2 with the 1st pivot 3, therefore, the top ends 28 of handle 2 contacts with inner bottom surface 29, does not have the implantation site thereby handle 2 remains on this.
If be pressed into button 22, because it drives the driven male member 24 of male member 23 push handle 2, so handle 2 is the counterclockwise revolution of center in Fig. 3 with the 1st pivot 3.When handle 2 rotated to certain stage, the press direction of crooked leaf spring 27 produced and reverses, and therefore, this back handle 2 grips possible position because the effect strength of crooked leaf spring 27 suitably is ejected into.
So, when gripping handle 2 is pulled out it again, flexure plane 9a because of the bore edges portion 9 in the driven hole 8 of the side pushing locking plate 4 that is located at the operation male member 7 on the handle 2, so, locking plate 4 is that the center moves in the direction of the clock with the 2nd pivot 6 among Fig. 8, and its top 5 is deviate from by the socket part 30 that is located on the framework, so, the door 31 that housing 1 is installed has just been driven lock, and 2 31 of handles just are opened again.
When locking door 31, handle 2 is pressed in the housing 1, because the flexure plane 10a of the bore edges 10 of side in addition in the driven hole 8 of aforesaid operations male member 7 pushings, locking plate 4 is that the counter-clockwise direction rotation is done at the center with the 2nd pivot 6 among Fig. 8,5 on its top enters in the above-mentioned pod 30, thus, door 31 is locked on the doorframe once more.

Followingly embodiments of the invention are described with reference to accompanying drawing.
In illustrated embodiment, on the cardinal extremity of the operation male member 7 of handle 2, be provided with and cross axis hole 11, handle 2 is journaled on the housing 1 by the 1st pivot 3 of pin shape and haunts freedom on housing 1, above-mentioned the 1st pivot 3 is inserted into and crosses installing hole 14,15 and aforementioned crossing in the axis hole 11, above-mentioned crossing on the left and right sides sidewall 12,13 that installing hole 14,15 is located at housing 1.The locking plate 4 that is configured on the back side of housing 1 is journaled on the housing 1 by the 2nd pivot 6 of Screw shape, and the axis hole that wears 16 that aforementioned the 2nd pivot 6 passes with driven hole 8 adjacency is screwed on the rear wall parts 17 of housing 1.The other Screw 18 that is screwed on the housing rear wall 17 is in the driven hole 8, the guiding means on floating when the head of Screw 18 becomes the rotation of the locking plate 4 that stops plane handle device.
Accommodating recess 19 with handle on housing 1 adjoins and is provided with the driven hole 20 of button, in driven hole 20, accommodating the button 22 that resets by compression helical spring 21 pushings, the driving male member 23 of protrusion on the lateral surface of button 22 contacts with driven male member 24, and this driven male member 24 is arranged on the handle cardinal extremity.In the mounting groove 26 at the top ends back side of the mounting groove 25 of the inner bottom surface 29 of housing 2 and handle 2, inserting the crooked end of crooked leaf spring 27.
In addition, when carrying out the bending machining of peritreme portion 9,10, the cross section of the bar shaped projection to be configured as shown in Figure 9 is circular, and is not only rectangular-shapedly, even locking plate 4 also can use conversely, can be used for L.H.flapped door and R.H.flapped door.
In the present invention, locking plate 4 along with in the housing 1 of handle 2 go out to establish rotation and when between the open and close lock position, carrying out forward and reverse rotation, because flexure plane 9a, the 10a of the side of operation male member 7 and the bore edges portion 9,10 in driven hole 8 are sliding-contacts, so, the frictional force of comparing with traditional product between the prominent part 7 of bore edges portion 9,10 and operation reduces significantly, prevented the scratch of the operation male member 7 that causes by bore edges portion 9,10, even so use the accident of losing that also can not operate male member 7, so have good durability prolonged and repeatedly.
And in locking plate of the present invention, the processing that bends up of the punch process in driven hole 8 and bore edges portion 9,10 is implemented simultaneously, so the manufacturing processing of operation male member was both simple and with low cost, its practical value is very big.
