Description
2364346 Fastening Arrangement The present invention relates to fastening
arrangements, and particularly but not exclusively to arrangements for fastening attachments to vehicles.
According to the present invention there is provided a fastening arrangement comprising a retaining member locatable on an object and defining a resilient passage tapering toward a retaining surface, and a second member having a retaining formation which when the second member is pushed into the passage of the retaining member locates against the retaining surface whereby to releasably hold the arrangement together.
Preferably the retaining surface defines the passage, desirably at one end, such that when located the second member extends through the passage with the retaining formation external thereof.
Preferably the passage tapers from an exterior surface to the retaining surface, such that the second surface may be on the opposing sides of the retaining member. The passage may taper, desirably along the majority of its length, toward a non-tapering section thereof which opens onto the retaining surface.
The retaining member may be shaped to locate on an object to which the arrangement can be used to fasten a further object.
The retaining member may comprise a recess to receive a part or portion of an object. The retaining member may be generally annular, with the passage extending therethrough and the locating recess therearound, preferably for location of the member in an aperture of an object.
The retaining member may be made of resilient material such as rubber, elastomer, plastics or other suitable material.
Preferably the second member comprises an elongate body on one end of which is provided the retaining formation, which retaining formation may be shaped to facilitate movement through the passage to cooperate with the retaining surface to releasably retain the second member. The retaining formation may be generally spherical.
Preferably the second member comprises a collar or similar formation on the body which collar abuts in use the external surface of the retaining member when the second member is located for use. The position of the collar may be to provide some compression of the retaining member to secure location.
Preferably the second member provides means for attachment of a second object thereto whereby to provide for releasable fastening of a second object to an object. The attachment means may comprise first and second parts interconnectable about the second object. The first part may comprise a portion of the body locatable against and extendible through an aperture in a second object, and so shaped to interconnect with a second part preferably so that the second object is located and desirably gripped between the first and second parts.
Preferably the first part comprises one or more resilient formations which extend through a second object to receive the second part. The second part may comprise a capping.
The first part may comprise toothed formations, between which a formation of the second part locates in use to secure attachment by biasing the toothed formations against the second object.
Further according to the present invention there is provided an attachment comprising a fastening arrangement substantially as described in any of the above preceding paragraphs.
An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawings, in which:- Fig. 1 shows a retaining member of a fastening arrangement according to the present invention; Fig. 2 shows a second member of a fastening arrangement according to the present invention; Fig. 3 shows a retaining cap of the fastening arrangement according to the present invention; and Fig. 4 is a diagrammatic cross-section of a fastening arrangement visibly holding two objects together.
in more detail the invention provides a fastening arrangement 10 comprising a retaining member 12 locatable on an object 0 and defining a resilient passage 14 tapering towards a retaining surface 16, and a second member 18 having a retaining formation 20 which when the second member 18 is pushed into the passage 14 locates against the retaining surface 16 whereby to releasably retain the arrangement 10 together.
One application of the arrangement 10 of the present invention is for the releasable fastening of attachments to motor vehicles, for example headlamp and tail lamp guards. However, it will be appreciated that the fastening arrangement 10 can be used for the releasable attachment of many other objects together.
In more detail, the retaining member 12 comprises a generally annular body 22 of resilient material, such as rubber, elastomer, plastics or other suitable material. The passage 14 extends through the body 22. The passage 14 tapers from a first exterior surface 24 of the member 12 to the retaining surface 16, which is also an exterior surface. As will be seen in Figs. 1 and 4, the passage tapers from the exterior surface 24 over a majority of its length in a direction toward the retaining surface 16, and then continues toward the retaining surface 16 with generally constant cross-section.
The exterior surface 24 is shaped to taper outwardly towards an object on which the retaining member 12 is locatable for use.
A groove 26 extends around the peripheral edge 28 of the fastening member 12 to receive in use the edges 20 of an aperture of an object 0.
The second member comprises a generally elongate body 32 of substantially rigid material, such as plastics or metal. The retaining formation 20 is provided on one end thereof. The retaining formation 20 is generally spherical.
Part way along the length of the body 32 is provided a collar 34 which provides an abutment surface 36.
At the other end of the body 32 is an attachment arrangement 38 for the attachment of a further object 02. The arrangement 38 comprises a second collar formation 40 toward the end of the body 32 and from which extend two resilient, toothed projections 42 which are shaped to be locatable through an aperture 44 in an object 02 to locate the region of the object 02 defining the aperture 44 in a recess 46 defined between the collar 40 and the tooth formations 48. The attachment arrangement 38 also comprises a capping 50 which comprises a substantially hemispherical covering S2 from the inside of which extends centrally a locating projection 54 which is releasably locatable between the tooth projections 42.
In use, the retaining member 12 is located about an aperture defined by the edges 30 in an object 0. The retaining member 12 is located to receive the edges in the groove 26 extending therearound, such that the exterior surface 24 is presented on a side of the object to which a further object is to be releasably attached.
The second member 18 may be mounted to a further object 02 prior to location in the retaining member 12, or alternatively the member 18 may be located in the retaining member 12 and the further object 02 subsequently attached using the attachment arrangement 38. The following description is of the former, which is generally preferred, although it will be appreciated that the interconnection and location of the various parts is very similar and therefore will not be described separately.
The second member 18 is attached using the attachment arrangement 38 by pushing the tooth projections 42 through an appropriately sized aperture 44 formed in the further object 02. The relative sizes and dimensions of the toothed projections 42, recess 46 and collar 40 are adapted according to the size and nature of the further object 02 to which the arrangement 10 is to be attached.
The resilient nature of the toothed projections 42 causes them to close as they are inserted through the aperture 44 and then to spring open to be substantially parallel and relaxed once the tooth formations 48 are located outside the aperture 44 and the object 02 located in the recess 46. The capping 50 is then pushed over the toothed projections 42, the insertion of the locating projection 54 between the toothed projections 42 acting to push the toothed projections 42 apart to bear further against the object 02 to secure attachment. The cover 52 also provides an attractive and tamper-resistant cover.
To fasten the object 02 to the object 0, the second member 18 is offered up to the mouth of the passage 14 and pushed down the passage 14 in the direction of the tapering of the passage 14. The resilient nature of the annular body 22 facilitates location and insertion of the generally spherical retaining formation 20. The second member is pushed until the retaining formation exits the passage 14 to locate against the retaining surface 16. At this stage, the abutment surface 36 of the collar 34 locates against the exterior surface 24 and preferably provides some compression of the body 22 between the retaining formation 20 to secure location of the retaining member 12 on the body 0 and also to facilitate and secure location of the second member 18 in the retaining member 12. The sizes and dimensions of the interfitting parts are carefully chosen to provide the desired degree of releasable fastening for the particular application of the arrangement. External factors such as the possible presence 6 of water are important to take into account.
To release the objects 0, 02 from attachment, force can be applied to the fastening arrangement, which would usually be greater than any force they would normally experience trying to pull them apart, to draw the retaining formation 20 back through the passage 14. The resilient nature of the body 22 and the spherical shape of the retaining member facilitate such withdrawal.
The fastening arrangement therefore provides easy to use and efficient releasable fastening of two objects together. As mentioned above, one application of the fastening arrangement 10 is for the secure yetfeleasable attachment of headlamp, tail lamp and other covers on motor vehicles. The retaining member would be mounted in an aperture in the vehicle 0 and the second member attached or attachable to the cover 02. It will be appreciated however that the inventive principle of the fastening arrangement 10 has many applications, and the relative sizes and shapes of the means for mounting the retaining member 12 on an object and the attachment arrangement 38 can be modified according to the particular application in accordance with the present invention, Various modifications may be made without departing from the spirit or scope of the present invention.
Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
