RU96391U1 - HANDLE FOR LOCKING DEVICES - Google Patents

Abstract

 A handle for locking devices, comprising a handle connected to the rod and rotatable in the handle overlay, a handle position lock located in the handle overlay and designed to interact with the handle, characterized in that the handle on the inside of the cover is made in the form of a sleeve with at least one face designed to interact with the position lock, made in the form of a spring retainer with at least one bending rod spring located across ki and interacting with at least one edge of the sleeve.

Description

The utility model relates to the field of hardware and can be used in the design of the handles of locking devices designed to interact through the rod with the locking device and hold the handle in the desired operating position.

State of the art

The prior art various types of handles of locking devices designed to work with the locking mechanisms of the locks by means of a rod, mainly of square section. One of the features of these devices is the presence in them of structural elements that ensure the retention of the handle in the initial installation position.

A handle construction is known from RU 2238384, comprising a device for holding the door handle in a selected working position, including a holding part installed between the handle plate and the door, which, in cooperation with the handle shaft, holds the handle in the selected working position, and, on the other hand, allows rotation of the handle from one operating position to another, while the holding part has flexible holding elements for each side of the rod, located so that they are pressed against the shaft of the handle. With the relative simplicity of the described device, it has several disadvantages, one of which is the inability to use it in various designs of locking devices.

Handle designs for locking devices are also known, comprising a torsion spring and acting to return the handle to its initial position after turning the handle. An example of such a device is the assembly described in patent RU 2174175. The assembly includes a spring, a spring holder, a lock washer having cutouts that act in conjunction with tongues located on the periphery of the spring holder to allow the lock washer and spring holder to be detachably connected together in different rotation positions. The hole in the lock washer and the blind hole in which the square rod in the shaft is located are configured to receive the square rod in any one of the rotation positions. The obvious disadvantage of this device is the presence in it of many elements of complex shape, which leads to the complication of its manufacture and, accordingly, to a significant increase in cost. Moreover, the wear of interacting elements adversely affects the reliability of the device during long-term operation.

Utility Model Disclosure

The technical task of the utility model is to create a reliable and, at the same time, simple handle design for locking devices that works with various types of locking devices.

The problem is solved in that the handle for locking devices includes a handle connected to the rod and made with the possibility of rotation in the handle pad, the handle position lock located in the handle pad and designed to interact with the handle, while the handle on the inside of the pad is made in in the form of a sleeve with at least one face designed to interact with a position lock made in the form of a spring lock with at least one bending rod spring laid across the sleeve and interacting with at least one face of the sleeve.

The proposed design of the handle ensures its use with various types of locking devices due to the possibility of a simple replacement of the rods fixed or inserted into the handle. In this case, the rods may have different cross sections both in size and in shape.

Increased reliability and clarity of the device is ensured by the interaction of the retainer spring with a larger section of the handle sleeve relative to the cross section of the rod.

Brief Description of the Drawings

The utility model is illustrated by drawings, in which:

figure 1 is a side view of the handle for locking devices;

figure 2 is a view a of figure 1.

Utility Model Implementation

The handle for locking devices includes a handle 1 connected to the rod 2. The specified connection can be both detachable and one-piece. The handle 1 is mounted in the overlay of the handle 3 with the possibility of rotation. The shape of the lining 3 may be different. In the plate 3, as a rule, holes 4 are made for its fastening, for example, with screws or self-tapping screws. The axial displacement of the handle 1 relative to the lining 3 is limited by a washer 5 and a spring clip 6. The handle 1 on the inner side of the lining 3 is made in the form of a sleeve 7. At least one face 8 is made on the sleeve 7. If necessary, more rigid fixation of the position of the handle 1 , on the specified sleeve 7 can be made two parallel faces 8 relative to the axis of the handle 1. Inside the lining 3, the insert 9 is fixed. The insert 9 is designed to install the bending rod springs 9 located across the sleeve 7.

The operation of the handle for locking devices is provided by the position lock of the handle 1, made in the form of a spring clip with at least one bending rod spring 10 located across the sleeve 7 and interacting with at least one face 8 of the sleeve 7. Enlarged area of interaction of the rod bending springs 10 with face 8 of sleeve 7 (in comparison with the size of the shaft face) provides a clearer fixation of the position of the handle 1. For a better fit of the bending spring spring 10 to face 8 of the sleeve 7, the spring shaft in the contact area interacting with face 8 of sleeve 7 can be shaped accordingly.

Obviously, this description and the specific example given, although they characterize the preferred embodiment of the utility model, are provided for illustrative purposes only and should not be considered as limiting the scope of the invention.
