Abstract
Abstract A runner has a conventional back-set bearing and bearing pivot. An axially movable pin passes through the pivot to operate retaining components in the runner fork to lock the wheel against running and/or swivelling movement. The pin is operated by a trip cam housed in a casing which surrounds the pivot and locking pin. The casing may be made in two half-shells and has a lower beading which engages in a groove of the bearing pivot. The casing forms an attachment plug whereby the runner can be fitted to a foot of an article of furniture.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
In a runner, preferably a castor, comprising a housing structure with an axis and a running wheel rotatable on said axis, a back-set bearing pivot arranged on said housing structure, an axially movable locking pin passing through the bearing pivot, trip camming means arranged to act on said locking pin, and securing means arranged in said housing structure to be acted on by said locking pin to lock the running and/or swivelling movement of the wheel, the improvement which comprises a casing enclosing said bearing pivot and locking pin over substantially their entire extent, and forming an integral component part of the runner, said trip camming means being movably but inlosably enclosed within said casing and supported in said casing and force cOnnected to said locking pin and forming an integral component part of the runner, said casing forming a substantially smooth attachment plug by means of which the runner can be fitted in a tubular foot and the like and having near its upper end at least one horizontal bore which coincides with a bore of said trip camming means being enclosed in said casing to receive a control lever of said camming means.
Claim 2
Dependent Claim
195 words
In a runner, preferably a castor, comprising a housing structure with an axis and a running wheel rotatable on said axis, a back-set bearing pivot arranged on said housing structure, an axially movable locking pin passing through the bearing pivot, trip camming means arranged to act on said locking pin, and securing means arranged in said housing structure to be acted on by said locking pin to lock the running and/or swivelling movement of the wheel, the improvement which comprises a casing enclosing said bearing pivot and locking pin over substantially their entire extent, and forming an integral component part of the runner, said trip camming means being movably but inlosably enclosed within said casing and supported in said casing and force cOnnected to said locking pin and forming an integral component part of the runner, said casing forming a substantially smooth attachment plug by means of which the runner can be fitted in a tubular foot and the like and having near its upper end at least one horizontal bore which coincides with a bore of said trip camming means being enclosed in said casing to receive a control lever of said camming means.
Claim 3
Dependent Claim
16 words
A runner as claimed in claim 1, wherein the casing is formed of two half shells.
Claim 4
Dependent Claim
19 words
A runner as claimed in claim 1, wherein the casing is a die-cast metal component, for instance, of zinc.
Claim 5
Dependent Claim
19 words
A runner as claimed in claim 2, wherein the two half-shells are die-cast metal components, for instance, of zinc.
Claim 6
Dependent Claim
262 words
In a runner, preferably a castor, as claimed in claim 1, which runner comprises a housing structure with an axis and a running wheel rotatable on said axis, a back-bearing pivot arranged on said housing structure, an axially movable locking pin passing through the bearing pivot, trip camming means arranged above the upper end of said bearing pivot to act on the head of said locking pin, and securing means arranged in said housing structure to be acted on by said locking pin to lock the running and/or swiveling movement of the wheel, wherein there are two half-shells forming a casing enclosing said bearing pivot and locking pin over substantially their entire extent, and forming an integral component part of the runner, said camming means being movably but inlosebly enclosed within said casing and supported in said casing above the upper end of said bearing pivot and force connected to said locking pin and being turnable in said casing for acting on the head of said locking pin and form ing an integral component part of the runner, said two half-shells of said casing forming a substantially smooth attachment plug by means of which the runner can be fitted into a tubular foot and the like, which plug having near its upper end at least one horizontal bore arranged in at least one said half-shell which coincides with a bore of said trip camming means being enclosed in said casing to receive a control lever of said camming means after inserting or fitting said plug into a tubular foot or the like.
Claim 7
Dependent Claim
32 words
A runner as claimed in claim 5, wherein each half-shell has at its lower end an inner beading, and the back-set bearing pivot has an outer groove in which said beadings engage.
Claim 8
Dependent Claim
24 words
A runner as claimed in claim 5, wherein the two casing half-shells are held together at their upper and lower ends by retainer rings.
Claim 9
Dependent Claim
26 words
A runner as claimed in claim 7, wherein the lower retainer ring simultaneously acts as a tube end ring of said tubular foot and the like.
Claim 10
Dependent Claim
