Abstract

Abstract A slide structure having an elongated slide body having a pair of outwardly convergent continuous slide surfaces at each side thereof which are supported within longitudinally spaced pairs of vee blocks which vee blocks are carried by a base member. The vee blocks at each side of the slide body are pivotable with the vee blocks at one side being selectively biased to provide a selectable preload between the vee blocks and the slide body.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 138 words
A linear slide structure comprising: a base member, an elongated slide member having a pair of outwardly converging surfaces at each side thereof, respectively; lockable, pivotable support members carried by said base member and cooperable with said surfaces respectively, to support said slide member for linear movement with respect to said base member and pivotable with respect to the longitudinal axis of linear movement of said slide member about axes in a plane perpendicular to said longitudinal axis; and at least one of said support members being selectively movable laterally of the longitudinal axis of linear movement of said slide member to provide a preload on said slide member whereby said slide member is preloaded and said support members are locked to maintain said preload to support said slide member for relative linear movement with minimum lateral deviation.
Claim 2
Dependent Claim 138 words
A linear slide structure comprising: a base member, an elongated slide member having a pair of outwardly converging surfaces at each side thereof, respectively; lockable, pivotable support members carried by said base member and cooperable with said surfaces respectively, to support said slide member for linear movement with respect to said base member and pivotable with respect to the longitudinal axis of linear movement of said slide member about axes in a plane perpendicular to said longitudinal axis; and at least one of said support members being selectively movable laterally of the longitudinal axis of linear movement of said slide member to provide a preload on said slide member whereby said slide member is preloaded and said support members are locked to maintain said preload to support said slide member for relative linear movement with minimum lateral deviation.
Claim 3
Dependent Claim 62 words
A linear slide member as defined in claim 1 wherein said base member has an abutment portion located laterally outwardly from the support members at one side of said slide member, and said support members at said one side carry adjustable means cooperable with said abutment portion to bias said support members at said one side into engagement with said slide member.
Claim 4
Dependent Claim 27 words
A linear slide structure as defined in claim 1 wherein said support members include slideways of a low coefficient of friction material engagable with said surfaces, respectively.
Claim 5
Dependent Claim 27 words
A linear slide member as set forth in claim 1 wherein said support members comprise a pair of support members at each side of said slide member.
Claim 6
Dependent Claim 21 words
A linear slide member as set forth in claim 1 wherein said pairs of converging surfaces converge at the same angle.
Claim 7
Dependent Claim 32 words
A linear slide member as set forth in claim 1 wherein said pivotable movement is permitted by means of openings in said block members surrounding a screw shank of smaller cross section.
