Mounting arrangements

Claim 2

A mounting arrangement comprising two members for mounting one upon the other, two parts carried by a first of said members, the two said parts having elongated edges respectively which are disposed in spaced substantially parallel relationship to one another on said first member to define an elongated guideway therebetween for receiving a portion of the second member, one of said parts including clamping means for exerting a clamping Force transversely of said elongated guideway to clamp said portion of said second member in the guideway against the other said part, said clamping means comprising an elongated displaceable element carried by said one part and extending lengthwise of said guideway, and means for applying compression to one end of said element in a direction lengthwise of said guideway to squeeze said element and cause it to project transversely into said guideway and thereby exert said transverse clamping force along a line parallel to said elongated edge of the other said part.

Claim 3

A mounting arrangement according to claim 1 wherein said element is an element of resilient material and the compression-applying means is operative to squeeze said element to project into said guideway by deformation of said element.

Claim 4

A mounting arrangement according to claim 2 wherein said one part includes a body having an elongate recess therein extending lengthwise of said guideway, and wherein said resilient element is a bush fitting into said recess.

Claim 5

A mounting arrangement according to claim 3 wherein said compression-applying means includes a screw extending through said bush within and lengthwise of said recess to screw into the said body.

Claim 6

A mounting arrangement according to claim 1 wherein said one part includes an inclined shoulder, and wherein said element is a wedge-shaped element having at least one inclined face positioned to bear on said shoulder, the compression-applying means including means for applying force to said wedge-shaped element to urge said inclined face against said shoulder and thereby squeeze said wedge-shaped element to cause it to project into said guideway.

Claim 7

A mounting arrangement according to claim 5 wherein said one part includes a body having a recess therein extending lengthwise of said guideway to receive said wedge-shaped element, and wherein said compression-applying means includes a screw extending through said wedge-shaped element within said recess to screw into the said one part.

Claim 8

A mounting arrangement according to claim 1 wherein said parts are formed integrally with said first member.

Claim 9

A mounting arrangement for printed-circuit boards, comprising a structure having a pair of opposed walls spaced from one another to define therebetween a compartment for receiving said boards, each of said walls carrying a series of mutually-spaced parts to define between successive ones of said parts a set of elongated guideways for receiving marginal portions of respective ones of said boards inserted into said compartment, the guideways of each set being aligned with individual ones of the guideways of the other set whereby each inserted board is received in guideways of the two walls, and a plurality of clamping means carried by said parts and each operable selectively to exert force transversely of a respective one of said guideways for clamping the marginal portion of a said board inserted in that guideway, each said clamping means comprising an elongated, displaceable clamping element extending in a direction substantially parallel to its associated guideway, and means for applying compression to one end of each said clamping element to squeeze said element and cause it to project into the said associated guideway and thereby exert said transverse clamping force along a line therein.

Claim 10

A mounting arrangement for printed-circuit boards, comprising a structure having a pair of opposed walls spaced from one another to define therebetween a compartment for receiving said boards, each of said walls carrying a series of mutually-spaced parts to define between successive ones of said parts a set of elongated guideways for receiving marginal portions of respective ones of said boards inserted into said compartment, the guideways of each set being aligned with individual ones of the guideways of the other set whereby each inserted board is received in guideways of the two walls, and a plurality of clamping means carried by said parts and each operable selectively to exert force transversely of a respective one of said guideways for clamping the marginal portion of a said board inserted in that guideway, each said clamping means comprising an elongated, displaceable clamping element extending in a direction substantially parallel to its associated guideway, and means for applying compression to one end of each said clamping element to squeeze said element and cause it to project into the said associated guideway and thereby exert said transverse clamping force along a line therein.

Claim 11

A mounting arrangement according to claim 8 wherein each said clamping element is an element of resilient material.

Claim 12

A mounting arrangement according to claim 8 wherein each said clamping element is a wedge element.
