Abstract
Abstract A device which is based on the bayonet principle for fastening an at least partially panel-shaped member to a fixed member by means of a key-shaped stud having a lateral projection or bit provided on the shank, which stud can be passed through subsequent holes in the panel and in the fixed member, which holes allow the passage of the shank and the projection, and subsequently after rotation of the shank the projection can engage in a recess in a resilient element of the fixed member so that withdrawal of the stud is prevented.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A device for fastening an at least partially panel-shaped member to a fixed member comprising a key-shaped stud having a lateral projection or bit provided on its shank, which stud can be passed through holes in the panel and in the fixed member, which holes allow the passage of the shank and the projection, and subsequently after rotation of the shank the projection can engage in a recess in a resilient element of the fixed member so that withdrawal of the stud is prevented, said fixed member being a bush having at one end an annular axially resilient portion which is connected to the remainder of the bush through a small part only of its circumference and is provided with a recess which is located substantially diametrically opposite the said small portion and in which the lateral projection of the stud inserted into the bush can engage.
Claim 2
Independent Claim
147 words
A device for fastening an at least partially panel-shaped member to a fixed member comprising a key-shaped stud having a lateral projection or bit provided on its shank, which stud can be passed through holes in the panel and in the fixed member, which holes allow the passage of the shank and the projection, and subsequently after rotation of the shank the projection can engage in a recess in a resilient element of the fixed member so that withdrawal of the stud is prevented, said fixed member being a bush having at one end an annular axially resilient portion which is connected to the remainder of the bush through a small part only of its circumference and is provided with a recess which is located substantially diametrically opposite the said small portion and in which the lateral projection of the stud inserted into the bush can engage.
Claim 3
Dependent Claim
48 words
A device as claimed in claim 1, wherein the shank of the stud comprises two aligned cylindrical portions, of which the portion remote from the head has a diameter smaller than that of the other portion, is provided with the lateral projection and terminates in a conical portion.
Claim 4
Dependent Claim
27 words
A device as claimed in claim 1, wherein the central portion of the bush is provided with at least one circumferential rib which acts as a barb.
Claim 5
Dependent Claim
20 words
A device as claimed in claim 3, wherein each rib is gapped at at least one point of its circumference.
Claim 6
Dependent Claim
16 words
A device as claimed in claim 4, wherein the bush is made of a plastic material.
