Claim 6

The invention as set forth in claim 3, in a combination in which the spacing of the two abutments, and the size and shape of the fulcrum portion and adjacent portions of the first support member, are such that the first support member is firmly connected to the second support member by compressive stress induced into the portion of the first support member extending between the two said abutments.

Claim 7

Support means by which a first support member is supported by a second support member, the second support member being provided with an elongated recess opening to a face of the second support member; the portion of the first support member supportively engageable with the said recess of the second support member being such that it is insertable freely thereinto, into a first relative position, by first positioning the said portion into the recess, and then, upon applying a twisting force to the outer portion of the first support member about the general axis of the recess, the said engageable portion of the first support member is caused to snugly engage the said recess as the parts are relatively moved thereby to a second relative position of firm support of the first support member by the second support member; the first support member having a fulcrum portion displaced transversely of the outer portion; a connecting portion between said outer portion and said fulcrum portion having a surface adapted to bearingly engage a portion of the said elongated recess; in a combination in which the wall of the recess, which in the second relative position of the parts is engageable with a relatively outer portion of the first support member, is sloped such that it provides an undercut nature of the recess into which the relatively inner portion of the first support member is received when the parts are in their said second relative position.

Claim 8

Support means by which a first support member is supported by a second support member, the second support member being provided with an elongated recess opening to a face of the second support member; the portion of the first support member supportively engageable with the said recess of the second support member being such that it is insertable freely thereinto, into a first relative position, by first positioning the said portion into the recess, and then, upon applying a twisting force to the outer portion of the first support member about the general axis of the recess, the said engageable portion of the first support member is caused to snugly engage the said recess as the parts are relatively moved thereby to a second relative position of firm support of the first support member by the second support member; the first support member having a fulcrum portion displaced transversely of the outer portion; a connecting portion between said outer portion and said fulcrum portion having a surface adapted to bearingly engage a portion of the said elongated recess; in a combination in which the wall of the recess, which in the second relative position of the parts is engageable with a relatively outer portion of the first support member, is sloped such that it provides an undercut nature of the recess into which the relatively inner portion of the first support member is received when the parts are in their said second relative position.

Claim 9

The invention as set forth in claim 5 in a combination in which the shape of the said engageable portion of the first support member and the said recess is co-ordinated such that resilient deformation is imparted to either or both of the engageable portion of the first support member and/or the walls of the recess, by the twisting force which moves the parts from the first relative position to the second relative position.

Claim 10

The invention as set forth in claim 5 in a combination in which the shape of the said engageable portion of the first support member and the said recess is co-ordinated such that a toggle-type retention of the engageable portion of the first support member is made by walls of the recess, by the twisting force which moves the parts from the first relative position to the second relative position.
