Description

Manual controls for door or window locks

technical field

The present invention relates to a manual control device for manually controlling a door or window lock.

Background technique

Such known devices generally have a handle, a square actuating pin for activating a mechanism that engages in the axial cavity of the neck of the handle, and a block for securing the handle to the profile of a door or window .

Many devices currently known contemplate pre-assembly of some components, which can be cumbersome and time-consuming due to the fact that special tools are required.

For this reason, it is sometimes preferred to provide the installer with a device that is fully pre-assembled and ready to be installed on the door or window.

In this case, the installer cannot from time to time adjust the configuration of the product to the specific door or window to which it must be installed.

In this case, for example, if the door or window differs in the length that the square pin must have for connection with the lock, a product that differs only in the length of the square pin must be provided.

It goes without saying that this complicates the inventory management, product transport and supply logistics faced by installers.

Description of drawings

Other features and advantages of the invention will appear more fully from the description of the manual control device according to the invention, shown by way of an indicative and non-limiting example in the accompanying drawings, wherein:

Figures 1 and 2 show a front exploded perspective view and a rear exploded perspective view of a device according to the invention;

Figure 3 shows a plan view of the block;

Figure 4 shows a vertical section of the manual control along its axis.

Detailed ways

With reference to the cited figures, there is shown a manual control device for manually controlling the lock of a door or window, which is indicated in its entirety by reference numeral 1 .

The device 1 comprises a handle 2 with a handle 8 and an axial hollow neck 7, an actuating pin 4 for actuating the lock, a block 3 for securing the device 1 to the profile of a door or window, and a handle for rotating Rotary bushing 5 of part 2.

The rotating bush 5 is integral with the handle 2 and in particular extends axially from the neck 7 of the handle 2 and is arranged through the hole 6 (in this case circular shape) of the block 3 .

A pin 4 (in this case having a square cross-section) is arranged to pass through the hole 6 of the block 3 and engages its front end in the rotating bush 5 .

Advantageously, the control device 1 comprises at least one stop ring 10 for preventing the extraction of the bushing 5 from the hole 6 of the block 3 .

The snap ring 10 is supported in a second seat 15 provided on the back of the block 3 surrounding the hole 6 and engages the first seat 11 of the bushing 5 .

The first seat 11 of the bushing 5 is formed in particular by the outer circumferential groove of the bushing 5 .

The stop ring 10 is elastic so as to be able to expand and contract, and in particular elastic and open.

The open elastic stop ring 10 may have an end with a gripping hole 10 for a gripper mounted in its second seat 15 provided on the back of the block 3 .

In this case, the stop ring 10 consists of a Sig ring.

The snap ring 10 is axially locked in its second seat 15 on the back of the block 3, but is free to radially expand and contract.

A stop ring 10 protrudes inside the hole 6 to be able to block the bushing 5 during its introduction into the hole 6 .

In particular, the peripheral portion of the snap ring 10 protrudes radially to the outside of the second seat 15 and to the inside of the cylindrical axial generatrix of the bore 6 where it engages the first seat of the bushing 5 11, thereby preventing its axial sliding.

Thus, the snap ring 10 holds the bushing 5 in place when traction is exerted on the shank 2, preventing it from being pulled out of the hole 3 of the block 6.

To mount the snap ring 10 on the back of the block 3, a clamp (if provided) that engages in the hole 10' and separates the ends can be used.

During the assembly step of the control device, due to the axial introduction of the bushing 5 into the hole 6, the end of the bushing 5 initially disengages the stop ring 10 until the stop ring 10 is aligned and engages, shrinks in the first part of the bushing 5 in the support 11.

The bushing 5 has a quick locking device for the extraction of the locking pin 4 .

The quick locking means for locking the extraction of the pin 4 from the bush 5 comprise a square frame-like flat sheet 18 inserted on the pin 4 and constrained to a plane 17 inclined relative to the axis of the bush 5 .

The flat sheet 18 has at least two opposite sides 18 ′, 18 ″ in contact with the two opposite sides 4 ′, 4 ″ of the pin 4 .

The flat sheet 18 has an axis of oscillation parallel to its two opposite sides 18', 18".

More precisely, with one of the two opposite sides 18, 18'', in particular with the side 18', the flat will be The sheet 18 is constrained to the side 17 ′ of the inclined plane 17 , thereby defining the axis of oscillation of the flat sheet 18 .

Since their distance in the direction orthogonal to the axis of oscillation of the two opposite sides 18', 18" of the flat sheet 18 varies according to the direction of oscillation, they are respectively loosened or fastened with respect to the corresponding sides of the pin 4 to The insertion of the pin 4 is accommodated or the extraction of the pin 4 from the bushing 5 is prevented, respectively.

To secure the bushing 5 in the neck 7 of the shank 2, at least one anti-extraction screw (not shown) is provided which engages in a hole 21 defined by grooves 22, 23 which match the bushing The cylindrical outer peripheral surface of the sleeve 5 and the cylindrical inner peripheral surface of the neck 7 of the shank 2 .

Rotation of the bushing 5 in the neck 7 of the handle 2 is also prevented by specially coupled interference elements 24, 25 which extend from the cylindrical outer peripheral surface of the bushing 5 and the neck 7 of the handle 2, respectively The cylindrical inner peripheral surface extends radially.

The hole 6 and the bushing 5 also have indexing means for the interaction of the angular position of the shank 2 .

The indexing means comprise recesses 26 on the outer periphery of the bushing 5 and elastically deformable projections 27 on the periphery of the hole 6 .

The recess 26 extends along the axial generatrix of the bushing 5 .

The protrusions 27 are obtained from the material of the body of the block 3 and/or are separate and independent parts fixed to the block 3 .

In the case shown, the protrusions 27 are formed by tabs of the material of the body of the block 3 delimited on the long sides by ridges 28 of the material of the body of the block 3 , or obtained by being embedded in the block 3 The tabs in the particular holder 29 are formed.

The block 3 is protected by a special mask with holes 31 for the pins 4 to pass through.

When the protrusions 27 are snap-engaged in the recesses 26, the indexing device allows the user to perceive the correct realization of the operating state (eg, in the case of a transverse window, the door or window is open, closed or raised).

Providing multiple indexing positions also helps improve security against theft: if a neutral indexing position is provided between two indexing positions associated with the two operating states, a thief must successfully pass through both indexing positions to change the door or the operational state of the window, which undoubtedly prolongs the time required to destroy and gain access to the door or window.

For assembly of the device 1 on a door or window, holes 32 for fixing screws (not shown) are provided in the block 3 for fixing the block 3 to the profile of the door or window in a conventional manner.

Assembly of the device 1 is carried out as follows.

Insert the rear end of the pin 4 through the hole 6 of the block 3 until the groove 11 passes through the hole 6 of the block 3 .

Then, use screws to fasten block 3 to the profile of the door or window.

Finally, the shank 2 is installed by inserting the bushing 5 into the front end of the pin 4 at a distance at least sufficient for the pin 4 to straddle the flat sheet 18 .

After insertion, the flat sheet 18 prevents the bushing 5 from being withdrawn from the pin 4 .

The device 1 can be dismantled by means of the hairpin 40 , with which the flat sheet 18 can be reached through the alignment channel 41 in order to turn its lying plane to release the square pin 4 .

Once the assembly of handle 2 and bushing 5 has been removed, in order to remove the square pin 4 from the housing of the lock, it is necessary to remove the block 3 from the profile of the door or window.

The manual control device according to the invention advantageously has a structure that is easy and quick to assemble and disassemble.

The position of the pin 4 can also be adjusted directly at the installation site in a generic manner according to the particular door or window on which the device is mounted.

Finally, the manual control device according to the invention can advantageously be mounted on only one side of the door or window or on both sides of the door or window.

The manual control device as envisaged herein is susceptible to numerous modifications and variations, all falling within the scope of the inventive concept; furthermore, all details may be replaced by technically equivalent elements.

In practice, the materials used as well as the dimensions can be determined according to requirements and available technology.
