Benefits of technology
The spring fastener effectively secures objects across a range of substrate thicknesses, reduces vibration-induced loosening, and minimizes rattling noises, enhancing safety, performance, and comfort in automotive applications.
Problems solved by technology
This arrangement presents many problems, among which, one of the most important is that in the case that one object is hollow, the nut has to be in place at the back of the hollow object before assembling the two objects together.
If for any reason the nut is misplaced, and / or if it becomes desirable to introduce a new fastening connection between the two objects, the task of achieving such connection becomes very difficult if not impossible for all practical purposes.
In addition, vibration during the operation of a device, such as an automobile or appliance for example, containing the two objects results very often in loosening of the bolt or “quick nut” and in either full disassembling of the objects from each other, or in a vibration noise which is most annoying and often of unacceptable levels.
The fasteners disclosed in the above patents and application have some difficulty when designed to be secured in the slot of a substrate (which may also be referred to as a first object) having a certain thickness, and instead they are used in a substrate having a different thickness or different width.
One such problem is rattling noises when the fasteners are used with a substrate which is thinner than the substrate that they have been designed for.

Embodiment Construction
[0036] As aforementioned, this invention pertains fasteners, and more particularly fasteners which attach one object to another object, with special emphasis to objects in the Automotive Industry.
[0037] As also mentioned earlier, there is a great need for a universal fastener of the general type described in the above patents, but being adaptable to be used with substrates having a broad range of thicknesses.
[0038] This invention provides fasteners which have the configurations required to satisfy the above need.
[0039] Referring now to FIGS. 1 to 6, there is depicted, a spring fastener 10 according to a preferred embodiment of the instant invention. The fastener 10 comprises a double layered head portion 12, which has an upper side or layer 14, and a lower side or layer 16. The upper side 12 has an engageable hole 18 on which an expanding member 20 (shown in FIG. 6) can engage and pass through. The expanding member 20 has a pitch 22, which is defined as the distance between two c...

This invention pertains fasteners which are characterized by adaptability of use with substrates, such as steel panels for example, of various thicknesses. This is achieved predominately by providing the fastener with legs having an origin section in the vicinity of the head of the fastener. Expansion promoters and / or anti-sliding elements improve considerably the separation resistance of objects connected with the fasteners of the present invention. Assemblies and vehicles comprising the spring fasteners of this invention, connecting two objects, one of the objects comprising a slot in which the fastener is inserted, and the other a hole, are also included within the scope of the instant invention. Provision of an elastic body in the vicinity of the bottom section of the fasteners provides water and gas proof properties, and further assist in the elimination of squeaking noises.
Description
RELATED APPLICATIONS [0001] This application claims priority of provisional patent applications 60 / 401,263, filed Aug. 06, 2002, and 60 / 403,202, filed Aug. 13, 2002, both of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION [0002] This invention pertains fasteners, and more particularly fasteners which attach one object to another object, with special emphasis to objects in the Automotive Industry. BACKGROUND OF THE INVENTION [0003] In the original conventional technology of fasteners employed to securely attach one object to another, such as for example one part to another in the case of an automobile or an appliance, has utilized a nut on one of the two objects, usually welded or glued to the back of said object, and a bolt passing through a hole on the second object in a manner to be engaged by the nut, thereby securing the two objects together. [0004] This arrangement presents many problems, among which, one of the most important is that in the ...
