Abstract
Abstract A cylinder lock is mounted in an aperture in a panel by means of a retaining ring which has resilient teeth to grip a part of the lock housing which protrudes from the panel. A further ring defining a non-circular aperture is provided in the opening of the panel to co-operate with flats on the lock housing and prevent rotation of the housing in the panel. The lock comprises a main body portion and a hollow spigot projecting from the main body portion and a key receiving member disposed in the spigot wherein the spigot defines an opening at an open end of the spigot remote from the main body portion. The key receiving member defines a key slot which is adjacent the open end of the spigot. The main body portion overlaps a marginal portion of the panel adjacent the panel opening defined thereby and the spigot extends through the aperture from the main body portion and projects from the panel at a second side thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
258 words
An assembly comprising a panel defining a panel opening having a center, a boundary element which defines a non-circular aperture having a center and coinciding with a part of said opening, an annular retaining element and a lock comprising a main body portion and a hollow spigot projecting from the main body portion and a key-receiving member disposed in the spigot wherein the spigot defines an opening at an open end of the spigot remote from the main body portion, the key-receiving member defines a key-slot which is adjacent the open end of the spigot, the boundary element and the panel are in mutually gripping relation adjacent the panel opening to restrain rotation of the boundary element about the center of the panel opening relative to the panel, the main body portion lies at a first side of the panel, the main body portion overlaps a marginal portion of the panel adjacent the panel opening defined thereby, the spigot extends through said aperture from the main portion and projects from the panel at a second side thereof, the spigot has a non-circular profile which complements the shape of the aperture to restrain rotation of the lock relative to the boundary element about the center of the aperture, the open end of the spigot and the key-slot lie at the second side of the panel and wherein the retaining element lies at the second side of the panel, overlaps and engages the boundary element and is in gripping relation with the spigot to retain the spigot in the aperture.
Claim 2
Dependent Claim
258 words
An assembly comprising a panel defining a panel opening having a center, a boundary element which defines a non-circular aperture having a center and coinciding with a part of said opening, an annular retaining element and a lock comprising a main body portion and a hollow spigot projecting from the main body portion and a key-receiving member disposed in the spigot wherein the spigot defines an opening at an open end of the spigot remote from the main body portion, the key-receiving member defines a key-slot which is adjacent the open end of the spigot, the boundary element and the panel are in mutually gripping relation adjacent the panel opening to restrain rotation of the boundary element about the center of the panel opening relative to the panel, the main body portion lies at a first side of the panel, the main body portion overlaps a marginal portion of the panel adjacent the panel opening defined thereby, the spigot extends through said aperture from the main portion and projects from the panel at a second side thereof, the spigot has a non-circular profile which complements the shape of the aperture to restrain rotation of the lock relative to the boundary element about the center of the aperture, the open end of the spigot and the key-slot lie at the second side of the panel and wherein the retaining element lies at the second side of the panel, overlaps and engages the boundary element and is in gripping relation with the spigot to retain the spigot in the aperture.
Claim 3
Dependent Claim
194 words
An assembly comprising a panel defining a non-circular aperture, a retaining element and a lock comprising a main body portion, a hollow spigot projecting from the main body portion and a key-receiving member disposed in the spigot wherein said aperture has a boundary including two curved portions lying on a common curve and two rectilinear portions, each of which is a chord of the common curve, wherein the main body portion lies at a first side of the panel and the spigot extends through said aperture from the main body portion, the spigot has a non-circular profile which complements the shape of the aperture to restrain rotation of the lock relative to the panel about a center of the aperture, the spigot defines an open end at a second side of the panel, the key-receiving member defines a key-slot which is adjacent the open-end of the spigot and lies at the second side of the panel, the main body portion overlaps the panel and wherein the retaining element lies at the second side of the panel, overlaps the panel and is in gripping relation with the spigot to retain the spigot in the aperture.
Claim 4
Dependent Claim
194 words
An assembly comprising a panel defining a non-circular aperture, a retaining element and a lock comprising a main body portion, a hollow spigot projecting from the main body portion and a key-receiving member disposed in the spigot wherein said aperture has a boundary including two curved portions lying on a common curve and two rectilinear portions, each of which is a chord of the common curve, wherein the main body portion lies at a first side of the panel and the spigot extends through said aperture from the main body portion, the spigot has a non-circular profile which complements the shape of the aperture to restrain rotation of the lock relative to the panel about a center of the aperture, the spigot defines an open end at a second side of the panel, the key-receiving member defines a key-slot which is adjacent the open-end of the spigot and lies at the second side of the panel, the main body portion overlaps the panel and wherein the retaining element lies at the second side of the panel, overlaps the panel and is in gripping relation with the spigot to retain the spigot in the aperture.
Claim 5
Dependent Claim
69 words
An assembly according to claim 2 wherein the panel includes a boundary element and a carrier for the boundary element, the carrier has a thickness exceeding the thickness of the boundary element, the carrier has a boundary surface defining the aperture having a center, the boundary surface faces towards the center of the aperture and the boundary element is in mutual engagement with the carrier of the boundary surface.
