Abstract

A door handle assembly (1) includes a handle (2), a shaft (3) and a rosette (4). The assembly is constructed in a manner which enables it to be fitted to a square-section bar (14) of different commercially available lock mechanisms. To this end, the assembly includes a coil spring (8), a spring holder (9), a lock washer (12) having first members, e.g. tongues (9b), which coact with second members, e.g. notches (12a), on the periphery of the spring holder, such as to enable the lock washer and the spring holder to be removably joined together in different positions of rotation. The hole (13) in the lock washer (12) and the blind hole (5) that receives the square-section bar (14) in the shaft (3) are configured so as to enable the square-section bar to be received in any one of at least eight different positions of rotation, therewith enhancing the possibility of using the door handle assembly effectively with different commercially available lock mechanisms.

Description

The present invention relates to a set of door handle parts for mounting on a square bar which contacts the locking mechanism, and more particularly to a set of door handle parts as defined in the general part of claim 1.

Description of the Related Art

Many different types of door handle assemblies are known in the art and are designed to interact with a locking mechanism within a lock body via a square cross-section rod. In many cases, it is not possible to replace one of the commercially available door handles, among other things, because of the orientation of the square cross-section bar in its initial inactive position, i.e. when the torque is not applied. Thus, the choice of handle set or assembly when it comes to replacing the handle of a locking mechanism compatible with a door lock body is very limited.

This is a serious drawback, especially as the rich and aesthetic design of the door handles has become more prevalent. It causes a serious inconvenience to the user when he or she is forced to replace the fully appropriate lock body and lock mechanism only to replace the door handle.

Objectives of the Invention

Accordingly, it is an object of the present invention to provide a set of door handle parts that could be adapted for use with different locking mechanisms, thereby providing a practically unlimited use of the door handle set.

It is another object of the present invention to provide a set of door handle components that allow the door handle to be easily replaced so as to allow the user to test various handles before deciding which handle will suit him or her most aesthetically or otherwise.

In addition to the orientation of the square cross-section rod in the inactive position, the above-mentioned problems also result in an important shape of the opening through which the bolts are inserted through the lock body for the safety of the corresponding door handle sockets. the thing is that a very limited number of handles can be individually used with commercially available locking mechanisms.

The essence of the invention

These and other objects are accomplished by this proposed set of door handle components having the features set forth in the definition in Clause 1 of the Definition.

Because the lock seal and spring retainer are formed effortlessly in the manner described, the handle mechanism can be freely adapted to fit the existing lock mechanism so as to guarantee a much wider selection of handles to be used with a variety of locking mechanisms than has hitherto been possible. This allows these handles to be used with locking mechanisms other than the locking mechanism or locking mechanisms for which the handle was originally intended.

The elements disposed along the perimeter of the lock spacer and the elements on the spring retainer interacting with each other can be constructed in various ways. For example, the lock seal may be provided with the protruding tabs in place of the grooves, and the spring retainer provided with the grooves that interact with said tabs.

In practice, it is better to have a lock gasket with more interacting elements than a spring bracket. The locking gasket - which has a central opening for adjusting the square section bar - can be positioned in several different positions according to the circumstances and will interact well with the spring retainer regardless of its position. The invention also encompasses the ability to rotate or reposition the lock spacer and thereby increase the number of possible spacer positions.

In practice, in a preferred embodiment, the locking gasket has twelve grooves spaced along the circumference of the gasket at 30 ° angular spacing. In addition, the spring holder has four axially protruding tongues, which are more often spaced at 90 ° angles.

This allows the invented handle assembly to be adapted to interact with a wide variety of commercially available locking mechanisms, namely the ability to rotate or reposition the locking gasket.

In a more preferred embodiment of the invention, the locking slot opening for the insertion of a square cross-section rod is formed capable of accommodating the rod in at least five, preferably eight or more different rotational positions. This type of orifice profile can be loosely formed in the shutter spacer by punching a hole with a square cross-section die and rotating the spacer some degrees between two successive stamping operations.

The blind hole for a square cross-section rod usually has a corresponding profile in the handle portion of the handle.

The further characteristic features and other advantages of the invention thus obtained will be apparent from the following description of one preferred embodiment of the invention, with reference to the accompanying drawings.

Brief description of the drawings

FIG. 1 is an enlarged view of a proposed set of door handle parts that cooperate with a square cross-section rod.

FIG. 2 is a sectional view of a square cross-section of the bar in the locking spacer region, showing the spring retainer mounted in the first position.

FIG. 3 is a sectional view corresponding to FIG. 2, and illustrates the handle assembly assembly by further disassembling and rotating the locking gasket 30 ° and renewed engagement of tongues protruding from the spring retainer.

Detailed description of embodiments

FIG. 1 is a perspective, exploded view of a door handle assembly 1 comprising a door handle 2, a handle handle 3, a blind hole 5 at the shown end of the stem 3, and a square rod 14 mounted in the opening 5. The handle 3 is pivotally mounted limiter 4a helical springs or rotary springs 8 for one end portion 8a.

Although not shown, rosette 4 has openings for 6 bolts that pass through the locking mechanism (not shown) and screw into a similar rosette on the other side of the door (not shown) for which the door handle assembly is intended.

The other end 8b of the spring 8 is adapted to interact with the outwardly angled projection 9a on the spring holder 9, which also has a plurality of tongues 9b projecting axially opposite to the direction of the projection 9a.

The tongues 9b may optionally be inserted into respective grooves 12a disposed along the perimeter of the locking spacer 12 having a central opening 13 having a profile or configuration corresponding to a square cross-section rod 14.

Once the door handle assembly is assembled, the spring retainer 9 and the locking mechanism seal 12 are pivoted relative to each other and to other parts of the assembly so as to provide sufficient door handle function regardless of the orientation of the square crossbar 14 and apertures 6.

The door handle is replaced by releasing the various parts from the bar 14 and rotating the locking gasket 12 and the spring retainer 9 for an appropriately renewed o

engaging the tongues 9a in the grooves 12a and, at the same time, adapting the assembly to the new socket stop member 4a and the spring 8.

In the illustrated embodiments, the lock seal 12 has twelve grooves 12a spaced around its circumference at a common angular distance of 30 °. The spring retainer 9 has four rubber tongues 9b.

In order to increase the possibility of adapting a set of door handle parts to a variety of locking mechanisms, the rod receiving opening 13 in the locking spacer 12 is formed to receive the rod in eight different pivoting positions.

The blind hole 5 in the handle part 3 of the handle 1 has a corresponding configuration.

The ability to adjust the handle assembly to suit a variety of locking mechanisms is further enhanced by the ability to adjust the lock spacer 12, e.g. rotate the lock seal 180 ° about the vertical axis.

The lock ring 11 is disposed between the lock seal 12 and the spring retainer 9.

The door handle assembly according to the invention can be used with virtually any commercially available locking mechanism.
