Abstract
Abstract A cover for a part, such as a guideway, of a machine tool comprises telescopic cover elements each having a cover plate and depending side and end walls having inwardly turned flanges at their lower ends so as to embrace the guideway. The walls are formed of an elastically flexible material to permit the cover to be snapped onto the guideway whereupon the walls and bent inwardly flanges engage the guideway with light spring pressure. Wiper strips are interposed between telescoping elements to effect cleaning of the parts in response to relative telescoping movements.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
122 words
A cover for machine tools comprising a number of telescopically engaging cover elements adapted to be fitted for movement around the part of the machine tool to be covered, at least one region of each cover element being sufficiently elastically flexible that the cover element can be snapped perpendicularly to its normal direction of movement onto the part of the machine tool to be covered, each of said cover elements comprising a cover wall, a rear wall, and two side walls bent inwards toward one another at their edges to embrace said part, said side walls having a greater height than that of said rear wall and being of such elasticity as to rest with light elastic pressure sealingly against said part.
Claim 2
Dependent Claim
122 words
A cover for machine tools comprising a number of telescopically engaging cover elements adapted to be fitted for movement around the part of the machine tool to be covered, at least one region of each cover element being sufficiently elastically flexible that the cover element can be snapped perpendicularly to its normal direction of movement onto the part of the machine tool to be covered, each of said cover elements comprising a cover wall, a rear wall, and two side walls bent inwards toward one another at their edges to embrace said part, said side walls having a greater height than that of said rear wall and being of such elasticity as to rest with light elastic pressure sealingly against said part.
Claim 3
Dependent Claim
22 words
A cover according to claim 1 wherein the cover elements are manufactured at least partly from elastic, preferably thermoplastically mouldable plastics material.
Claim 4
Dependent Claim
43 words
A cover according to claim 1 including a rear wall forming a glider element adapted to be supported on the machine tool part to be covered and also the corres-ponding glider element lying against the side walls of the next larger cover element.
Claim 5
Dependent Claim
26 words
A cover according to claim 1 wherein said cover elements are manufactured partly from sheet metal and have an elastically flexible region composed of elastic material.
Claim 6
Dependent Claim
30 words
A cover according to claim 1 wherein selected positions of said cover elements are composed of plastics material and are protected by a material more durable than said plastics material.
Claim 7
Dependent Claim
33 words
A cover according to claim 1 wherein said cover walls are bent, in the region of their rear edges upwards and in the region of their front edges downwards, to form engagement faces.
Claim 8
Dependent Claim
39 words
A cover according to claim 6 wherein in the region of the front edge of each of said cover walls is provided a wiper strip, made at least partly from plastics material and partly covered by the bent edge.
Claim 9
Dependent Claim
29 words
A cover according to claim 7 wherein each of the side walls adjacent the cover wall is cut away in the region required for insertion of the wiper strip.
Claim 10
Dependent Claim
27 words
A cover according to claim 8 wherein the height of the wiper strip is at least equal to the thickness of the material of the side walls.
Claim 11
Dependent Claim
26 words
A cover according to claim 1 wherein the cover wall is formed from a material of higher rigidity and strength than that of said side walls.
