Abstract
Abstract A slide mechanism in which a movable slide member slides in a stationary bearing element which restrains the slidable member against movement other than in the direction of sliding movement. Contact between the sliding member and the bearing element is linear at all locations of contact. Compacted foreign matter accumulating in the slide mechanism is broken up, loosened and ejected from the bearing element in response to sliding movement.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
140 words
A slide mechanism comprising: a first member; a second member; a bearing element on said first member; means on said bearing element and on said second member cooperating to mount said second member for sliding movement relative to said bearing element; said bearing element comprising means for restraining said second member against movement other than in the direction of said sliding movement; said bearing element and said second member comprising a planar contacting surface on one of the two and a convex contacting surface on the other of the two; and means on said bearing element and on said second member cooperating to restrict contact between the two to contact between a convex surface on one of the two and a planar surface on the other of the two at all locations of contact, thereby minimizing friction between the two.
Claim 2
Dependent Claim
140 words
A slide mechanism comprising: a first member; a second member; a bearing element on said first member; means on said bearing element and on said second member cooperating to mount said second member for sliding movement relative to said bearing element; said bearing element comprising means for restraining said second member against movement other than in the direction of said sliding movement; said bearing element and said second member comprising a planar contacting surface on one of the two and a convex contacting surface on the other of the two; and means on said bearing element and on said second member cooperating to restrict contact between the two to contact between a convex surface on one of the two and a planar surface on the other of the two at all locations of contact, thereby minimizing friction between the two.
Claim 3
Dependent Claim
38 words
A slide mechanism as recited in claim 1 wherein: said second member has a plurality of contacting surfaces; and said bearing element has a plurality of contacting surfaces each engaging a respective contacting surface of said second member.
Claim 4
Dependent Claim
85 words
A slide mechanism as recited in claim 2 wherein: said bearing element has two pairs of convex contacting surfaces; one of said two pairs of convex contacting surfaces comprising means for restraining said second member against movement in a first direction transverse to said direction of sliding movement; and the other of said two pairs of convex contacting surfaces comprising means for restraining said second member against movement in a second direction transverse to the direction of sliding movement and transverse to said first direction.
Claim 5
Dependent Claim
38 words
A slide mechanism as recited in claim 3 wherein: the convex contacting surfaces in said one pair are in mutually opposed vertical alignment; and the convex contacting surfaces in said other pair are in mutually opposed horizontal alignment.
Claim 6
Dependent Claim
36 words
A slide mechanism as recited in claim 1 and comprising: means on said bearing element and on said second member cooperating to eject loose foreign matter accumulating between the two, in response to said sliding movement.
Claim 7
Dependent Claim
34 words
A slide mechanism as recited in claim 5 wherein said last recited means further comprises: means for breaking up and loosening compacted foreign matter accumulating between the two in response to said sliding movement.
Claim 8
Dependent Claim
32 words
A slide mechanism as recited in claim 6 wherein said last recited means comprises: a cavity defined by adjacent surfaces of the bearing element and the second member between adjacent contact locations.
Claim 9
Dependent Claim
89 words
A stationary bearing element for use with a movable slide member, said bearing element and said slide member comprising a planar contacting surface on one of the two and a convex contacting surface on the other of the two, said stationary bearing element comprising: means for restraining the movable slide member against movement other than in the direction of sliding movement; and means for restricting contact between said bearing element and said slide member to contact of a convex surface with a planar surface at all locations of contact.
Claim 10
Dependent Claim
89 words
A stationary bearing element for use with a movable slide member, said bearing element and said slide member comprising a planar contacting surface on one of the two and a convex contacting surface on the other of the two, said stationary bearing element comprising: means for restraining the movable slide member against movement other than in the direction of sliding movement; and means for restricting contact between said bearing element and said slide member to contact of a convex surface with a planar surface at all locations of contact.
Claim 11
Dependent Claim
38 words
A stationary bearing element recited in claim 8 wherein said restraining means and said contact-restricting means are embodied in a plurality of contacting surfaces each comprising means for engaging a respective contacting surface on the movable slide member.
Claim 12
Dependent Claim
86 words
A stationary bearing element as recited in claim 9 and comprising: two pairs of said convex contacting surfaces; one of said two pairs of convex contacting surfaces comprising means for restraining said movable slide member against movement in a first direction transverse to said direction of sliding movement; and the other of said two pairs of convex contacting surfaces comprising means for restraining said movable slide member against movement in a second direction transverse to the direction of sliding movement and transverse to said first direction.
Claim 13
Dependent Claim
39 words
A stationary bearing element as recited in claim 10 wherein: the convex contacting surfaces in said one pair are in mutually opposed vertical alignment; and the convex contact surfaces in said other pair are in mutually opposed horizontal alignment.
Claim 14
Dependent Claim
35 words
A stationary bearing element as recited in claim 8 and comprising: means for permitting the ejection of loose foreign matter accumulating between the bearing element and the slide member, in response to said sliding movement.
Claim 15
Dependent Claim
39 words
A stationary slide element as recited in claim 12 and comprising: means for permitting the breaking up and loosening of compacted foreign matter accumulating between the bearing element and the movable slide member, in response to said sliding movement.
Claim 16
Dependent Claim
29 words
A stationary slide element as recited in claim 13 wherein said last recited means comprises; an enlarged recess located between adjacent linear contact locations on the stationary bearing element.
