Abstract

FIELD: construction.

SUBSTANCE: present invention pertains to architectural hardware and relates to door handles. The handle has a hollow housing with an opening for fitting the handle, attached on the surface of the door. Inside the housing, a fixing mechanism is fitted, which has a piston rod and fixed on the retainer body. The fixing mechanism has guide, rigidly fixed to the handle. The piston rod is freely joined to the guide. On the piston rod there is a compression spring, between the guide and the support. The fixing mechanism has a support for the guide, restricting its rotation. The invention can be used with the same success on right sided and left sided doors.

Description

The invention relates to the field of hardware and relates to a handle for shutting a door, window or other similar element intended for landing on a rod, which acts in conjunction with a locking mechanism.

The prior art there are a large number of types of knots door handles, which are designed for joint action with the locking mechanism in the lock housing through a rod, for example, of square cross section.

From the Swedish patent 454715, a sash handle is known which is mounted on a square bar and includes a wall mounted socket in which the square bar is rotatably mounted in a blind hole made in the door handle. The handle interacts with a coil spring or torsion spring so that it returns to its initial position after turning the handle. The spring has first and second outward curved end parts for joint action with the stop elements on the socket and on the spring holder, respectively. The assembly also contains a lock washer having a central hole adapted to receive a square rod.

This handle does not provide interchangeability of commercially available door handles, among other reasons, due to the orientation of the square bar in its initial passive position, i.e. when it is not exposed to rotational force.

In addition, the location of the holes, which include the screws passing through the lock housing for mounting the corresponding outlets, is also significant, because a very limited number of handles can be used separately with commercially available locking mechanisms.

Another serious drawback is the inability to use these handles on the right or left sides of the door, without certain installation work, consisting, for example, in the rearrangement of the torsion spring.

Known handle for the sash of the application EP 0791703, 1997, which can be used for both right and left doors, in the body of which are two forks, directed towards each other and made elastic. The ends of the forks fix the square rod connected to the handle in one of four positions, due to which this handle can be used for left and right doors without installation work, consisting in the rearrangement of the handle parts. However, this design of the pen is unreliable in that the determination of its fixed positions is exclusively at the level of tactile sensations. In fixed positions, the handle is held only due to the elastic properties of the forks, which causes a large backlash and consequently increased wear. Another disadvantage is that the forces arising in the forks during rotation of the handle, lead to a quick break of their branches.

The technical task of the invention is the creation of a simple, reliable handle for the sash, which can work with any commercially available locking mechanism and can be used for left and right doors without any readjustment of its mechanism and rearrangement of parts.

This technical problem is solved in that the handle for the sash contains a hollow body fixed to the surface of the sash with an opening for mounting the handle, and a locking mechanism is placed in the body cavity, comprising a connecting rod and a stop fixed to the body. The locking mechanism further comprises a leash rigidly connected to the handle, and leash stops to limit its rotation, the connecting rod is pivotally connected to the leash, and a compression spring is placed on the connecting rod, located between the leash and the stop.

The emphasis can be made in the form of a stepped sleeve.

The connecting rod can be made in the form of at least two forks assembled by the package and directed one to the other, one of which is pivotally mounted on the stop, and the second fork is pivotally connected to the leash.

The connecting rod can be made in the form of three forks assembled by the package, one of which is pivotally mounted on the stop, the second fork is pivotally connected to the leash, and the third fork, identical to the first, is pivotally mounted on the same stop, while the forks are located in the package so that the second the fork is located between the first and third and is directed in the opposite direction from them.

Forks for swivel have each open groove and after a set of packages combined by springs, they are put open grooves on the stepped sleeve and the axis of the leash.

The handle for the sash contains a housing 11, mounted on the surface of the sash. In its cavity from the inside there is a mechanism for fixing the handle (partially shown). A leash 1 is rigidly mounted on the handle. A connecting rod 12 is pivotally mounted on it (Fig. 15). Between the leash 1 and the emphasis 8, mounted on the housing 1 inside the cavity, a compression spring 5 is put on the connecting rod 12.

The connecting rod can also be made in a more complex form, consisting of several elements, for example, a plug 2 is pivotally mounted on a lead 1, the branches of which are facing down. Towards it, on the stop 8, a fork 3 is installed, or most often two forks 3. To connect the lead 1 to the fork 2, the axis of the lead 4 is fixed on it with riveting. The forks are assembled into a package by means of compression springs 5. Moreover, the fork 2 has cylindrical recesses on each side with a radius coinciding with the radius of the spacer washer 6 of the leash 1. Thus, it is possible to reduce the backlash of the locking mechanism. The forks 2 and 3 of the connecting rod are arranged in parallel planes, their opposite branches are aligned in plan, and a compression spring 5 is put on each pair of branches. The forks 3 are identical to each other and are mounted on the stop 8. The package of forks with a set of springs is placed between the axle the leash 4 and the stop 8, for which the forks for the hinge have each open groove with a cylindrical bottom, and after a set of packages combined by springs, they are put open grooves on the stepped sleeve and the axis of the leash.

In order to prevent the handle from sliding on the surface of the external side of the housing, which can be painted or coated with some composition, a washer 7 is put down. bushings (Fig. 8). The entire set of the leash with washers is fastened with a lock washer 9. Above the handle with the leash 1, a stop of the leash 10 is installed. The stop 10 is intended to limit the rotation angles of the handle within 180 °.

The handle works in the usual mode for these mechanisms.

The proposed handle has high performance in operation, reliable, has no backlash and ensures smooth and noiseless operation of the handle. The handle easily changes to the left- or right-hand door by simply turning the handle 180 °. At the same time, turning the handle downward by 90 °, with further rotation it passes through the dead position and subsequently can work in a different range of rotation angles.

The use of compression springs ensures the durability of the device, smoother characteristics of changes in the effort on the handle when the handle is rotated through an angle from 0 ° to 60 ° in comparison with other designs, the backlash is reduced.
