Abstract
Abstract For supporting roof components, such as purlins or other roof bearers, above a ceiling, the invention provides a bearing comprising a base body which rests on the ceiling providing a plurality of inclined support surfaces, as well as individual support bodies each of wedge-like configuration providing a respective bearing surface resting upon the corresponding support surface, each support body being moveable upwardly on its support surface of the base body but being prevented from moving downwards in the opposite direction.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
101 words
A bearing for supporting separately and individually a plurality of upper components, comprising a base body having a plurality of inclined stationary support surfaces thereon, a plurality of individual wedge-shaped support bodies engaging said respective support surfaces, each of said support bodies being selectively positionable independently of the other support bodies along one support surface of said base body for selecting the desired elevation of the upper surface of such support body to support its upper component, and means securing each support body independently of the other support bodies against displacement downward along its support surface relative to said base body.
Claim 2
Dependent Claim
101 words
A bearing for supporting separately and individually a plurality of upper components, comprising a base body having a plurality of inclined stationary support surfaces thereon, a plurality of individual wedge-shaped support bodies engaging said respective support surfaces, each of said support bodies being selectively positionable independently of the other support bodies along one support surface of said base body for selecting the desired elevation of the upper surface of such support body to support its upper component, and means securing each support body independently of the other support bodies against displacement downward along its support surface relative to said base body.
Claim 3
Dependent Claim
27 words
The bearing defined in claim 1, the base body being of ridge shape and including two downwardly divergent flanks constituting the support surfaces of the base body.
Claim 4
Dependent Claim
30 words
The bearing defined in claim 1, and stationary wedge-shaped ledges on the bAse body, the support surfaces of the base body being formed as inclined upper surfaces of said ledges.
Claim 5
Dependent Claim
43 words
The bearing defined in claim 3, the securing means including generally horizontal teeth on the inclined upper surfaces of a ledge and teeth on the lower surface of a support body engageable with said teeth on the inclined upper surface of a ledge.
Claim 6
Dependent Claim
63 words
The bearing defined in claim 3, the securing means including upright grooves in opposite upright sides of a ledge, upright grooves in opposite upright sides of a support body corresponding to said upright grooves in the sides of a ledge, and a stirrup of inverted-U shape engageable in side grooves of such support body and in side grooves of such base body ledge.
Claim 7
Dependent Claim
47 words
The bearing defined in claim 3, the securing means including upright teeth on at least one upright side of a ledge and upright teeth on at least one upright side of a support body that can mesh with said teeth in an upright side of a ledge.
Claim 8
Dependent Claim
89 words
The bearing defined in claim 3, the securing means including upright teeth on an upright side of a ledge, upright teeth on an upright side of a support body facing said toothed upright side of a ledge, and an intermediate piece having upright teeth on both sides, the teeth on one side of said intermediate piece being capable of meshing with the teeth on said toothed ledge side while teeth on the other side of the intermediate piece are meshed with teeth on said toothed upright support body side.
Claim 9
Dependent Claim
58 words
The bearing defined in claim 1, the securing means including a groove in an inclined stationary support surface extending at an angle to a vertical plane perpendicular to a horizontal line in such inclined support surface, a slot in the support surface crossing said groove and a locking pin inserted through said slot and penetrating into said groove.
Claim 10
Dependent Claim
30 words
The bearing defined in claim 1, the inclined stationary support surfaces being arranged in a cluster such that vertical planes perpendicular to horizontal lines in such respective inclined surfaces intersect.
Claim 11
Dependent Claim
19 words
The bearing defined in claim 9, the plurality of inclined stationary support surfaces sloping downward toward a common point.
Claim 12
Dependent Claim
35 words
The bearing defined in claim 9, the inclined stationary support surfaces being arranged so that the vertical planes perpendicular to horizontal lines in the respective inclined surfaces intersect at substantially right angles to each other.
Claim 13
Dependent Claim
36 words
The bearing defined in claim 9, and spacer means located substantially midway between the inclined stationary support surfaces and projecting upward from the base body to a location above the upper surfaces of the support bodies.
Claim 14
Dependent Claim
57 words
The bearing defined in claim 1, two inclined stationary support surfaces being disposed so that vertical planes perpendicular to horizontal lines in such respective inclined support surfaces intersect, and spacer means disposed substantially centrally between such intersecting vertical planes and projecting upwardly from the base body to a location above the upper surfaces of the support bodies.
