DESC:TECHNICAL FIELD OF THE INVENTION
This invention relates generally to switching devices. More particularly the present invention relates to a holder assembly for holding two or more interlocked switching devices with minimum possible gap. The holder can be assembled at the time of installation of interlocking device and the unique construction of the holder avoids miss out of the same in assembly i.e. mistake proofing.

BACKGROUND AND THE PRIOR ART

The holder is designed for holding two or more interlocked switching devices. For proper working of interlocked devices, two factors play an important role i.e. minimum possible gap between the devices and no bow in the base plate/panel on which they are mounted.

In the present invention, a unique construction of the holder maintains minimum possible gap between the interlocked switching devices. In case of bow in the customer base plate, assembly of holder will not be possible. The unique design of the holder eliminates the possibility of holder miss out due to customer negligence, thereby making its use mandatory i.e. mistake proofing.

In the present invention holder ensures minimum gap between the interlocking and interlocked devices thus serving their functionality.

OBJECTS OF THE INVENTION
A basic object of the present invention is to overcome the disadvantages/drawbacks of the known art.

Another object of the present invention is to provide a holder assembly for holding two or more interlocked switching devices with minimum possible gap.

Yet another object of the present invention is to provide the holder assembly to avoid miss out of the holder during the installation i.e. mistake proofing.

These and other advantages of the present invention will become readily apparent from the following detailed description read in conjunction with the accompanying drawings.

SUMMARY OF THE INVENTION

The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the present invention. It is not intended to identify the key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concept of the invention in a simplified form as a prelude to a more detailed description of the invention presented later.

In an aspect of the present invention, there is provided a holder assembly for holding two or more interlocked switching devices with minimum gap in-between, said assembly comprising :
plural wings/flanges having pre-determined grooves so as to fixably engage with the said interlocked devices; and
a projection located intermediately to the said flanges;
wherein said projection accommodates a screw means for engagement of the holder assembly with the switching devices.

Other aspects, advantages, and salient features of the invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses exemplary embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

Accordingly the present invention provides a holder assembly useful for holding two or more interlocked switching devices with minimum possible gap. The holder can be assembled at the time of installation of interlocking device and the unique construction of the holder avoids miss out of the same in assembly i.e. mistake proofing.

The holder is designed for holding two or more interlocked switching devices. For proper working of interlocked devices, two factors play an important role i.e. minimum possible gap between the devices and no bow in the base plate/panel on which they are mounted. The unique construction of the holder maintains minimum possible gap between the interlocked switching devices. In case of bow in the customer base plate, assembly of holder will not be possible. The unique design of the holder eliminates the possibility of holder miss out due to customer negligence, thereby making its use mandatory i.e. mistake proofing.

Key benefits of the holder can be summarized as follow:
1. The holder ensures minimum gap between the interlocking and interlocked devices thus serving their functionality.
2. In case of a bow in customer panel, the installation of the devices will not be possible i.e. mistake proofing.
3. Unique design of the holder avoids miss out of the holder during the installation i.e. mistake proofing.

Holder is designed with two wings/flanges (1) to hold the electrical switching devices and one projection (2) which is essentially cylindrical through which mounting screw will pass. The flanges comprises groove means for sufficiently engaging with the interlocking/interlocked devices. The interlocking device housing (refer image 4 & 5) is modified and material surrounding the existing mounting screw hole (3 & 4) is removed such that the projection of holder can be accommodated in it. Hence during the installation of the interlocking device, if customer misses out holder, assembly of the interlocking device is not possible making use of holder mandatory. ,CLAIMS:1. A holder assembly for holding two or more interlocked switching devices with minimum gap in-between, said assembly comprising :
plural wings/flanges having pre-determined grooves so as to fixably engage with the said interlocked devices; and
a projection located intermediately to the said flanges;
wherein said projection accommodates a screw means for engagement of the holder assembly with the switching devices.

2. Assembly as claimed in claim 1, wherein said projection is essentially cylindrical.

3. Assembly as claimed in claims 1 and 2 wherein said projection is accommodated ergonomically in the interlocking device housing.

4. A holder assembly for holding two or more interlocked switching devices with minimum gap in-between as herein substantially described and illustrated with the accompanying drawings.
