The following specification particularly describes the invention and the manner in which it is to be performed.

Field of the Invention
The present invention relates to nut assembly. More  particularly the invention relates to a floating nut assembly for captive screws.

Background of the Invention
Nut assemblies have been used extensively on panels and other parts  providing a means for allowing limited floating movement of the nut so that it can be more easily engaged by a bolt. Such a fastening device includes a receptacle which is provided by a flat plate from which portions are bent to engage and retain flanges projecting from the nut. This holds the nut to the receptacle  while allowing movement of the nut.

Further  captive nuts are also used extensively in card guides for captive screws that project out of the faceplate of a panel. The use of captive nuts requires larger area and cut-out for riveting the nutserts. The card guides require floating nut assemblies for eliminating JIJO issues caused due to manufacturing. However  the card guides have specific dimension requirements which are difficult to achieve for accommodating a nut assembly.

In view of the above mentioned problems it is required to provide an assembly that overcomes the dimensional limitations of the prior art assemblies.

Summary of the Invention
Accordingly  the present invention provides a floating nut assembly  the assembly comprising: a floating member; a first member having a recessed entry at front end and an aperture at rear end for accommodating the floating member from the rear end; and a second member having a hexagonal flange at front end and an aperture at rear end for accommodating the floating member from the rear end; wherein the floating member is accommodated in between the first member and the second member such that a recessed threading is formed to provide a float space.

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.
Various embodiments of the present invention provides a floating nut assembly  the assembly comprising a floating member; a first member having a recessed entry at front end and an aperture at rear end for accommodating the floating member from the rear end; and a second member having a hexagonal flange at front end and an aperture at rear end for accommodating the floating member from the rear end; wherein the floating member is accommodated in between the first member and the second member such that a recessed threading is formed to provide a float space.

Fig. 1 shows a floating nut assembly 100 in accordance with an embodiment of the present invention. The floating nut assembly 100 includes a floating member 120  a first member 110  and a second member 130. The floating member 120 is accommodated between the first member 110 and the second member 130.

In an embodiment of the invention  the floating member 120 has a rectangular outer surface 122 and a central hole 124. The rectangular outer surface 122 is tapered at corners (122a  122b  122c  122d).

In an embodiment the first member 110 has a recessed entry at front end 112 and a rectangular aperture 140 at rear end 114. The first member 110 accommodates the floating member 120 from the rear end 114. The rectangular aperture 140 is tapered at corners for accommodating the floating member 120.

In an embodiment  the second member 130 has a hexagonal flange 131 at front end 132 and a rectangular aperture 150 at rear end 134 for accommodating the floating member 120 from the rear end 134.
In an embodiment  the floating member 120 is accommodated between the first member 110 and the second member 130 such that a recessed threading is formed to provide a float space.

In an embodiment the rectangular apertures (140  150) are tapered to accommodate the floating member 120.

In an embodiment the floating member 120 has a central hole 124 for enabling recessed entry of a captive screw (not shown).

In an embodiment  the assembly 100 is adapted on a card guide (not shown).

In an embodiment  the first member 110 and the second member 130 have threading at outer diameters (113  133) of the rear ends (114  134) for engaging each other to form an enclosure as shown in Fig. 1 and Fig. 2.

In an embodiment  diameters of outer surface 116 of the first member 110 and outer surface (136) of the second member 130 are same as shown in Fig. 1.
In an embodiment  diameter of the rectangular apertures (140  150) is less than the diameters of outer surface (116  136) of the first member 110 and the second member 130.

In an embodiment  widths of the rectangular aperture (140  150) of the first member 110 and second member 130 are sufficient to accommodate the floating member 120.

In an embodiment  surface of the floating member 120 is devised to prevent 360 degree rotation of the floating member 120.

In an embodiment  the floating member 120 is preferably rectangular in shape as shown in Fig. 1 and 2.

It shall be apparent to a person skilled in the art that the shape of the floating member can be of any type with a function to prevent rotation of the floating member inside the enclosure. The rectangular shaped floating member 120 is by way of example and not to limit the scope of the invention in any manner.

In an advantageous aspect  the floating nut can fit into a card guide of the size 12.00mm whereas the standard floating nuts require a minimum card guide width of 17.6 mm.

While the foregoing is directed to embodiments of the present invention  other and further embodiments of the invention may be devised without departing from the basic scope thereof  and the scope thereof is determined by the claims that follow.
