Total Claims: 14
Claim 1
Independent Claim
123 words
A protective cover for guide paths of machine tools, comprising: a plurality of overlapping cover sheets movable into each other telescopically; running rollers and slide members, respectively; each of said cover sheets being supported at the forward end wall with said running rollers and slide members, respectively, on the guide path and at the rear end on the next smaller of said cover sheets; a plurality of energy accumulators producing return movement forces during movement out and movement in of said cover sheets from a center position, and disposed between said cover sheets; and said return movement force being equal to zero in said center position and is greatest in the respective end positions upon moving-out and moving-in, respectively, of said cover sheets.
Claim 2
Dependent Claim
123 words
A protective cover for guide paths of machine tools, comprising: a plurality of overlapping cover sheets movable into each other telescopically; running rollers and slide members, respectively; each of said cover sheets being supported at the forward end wall with said running rollers and slide members, respectively, on the guide path and at the rear end on the next smaller of said cover sheets; a plurality of energy accumulators producing return movement forces during movement out and movement in of said cover sheets from a center position, and disposed between said cover sheets; and said return movement force being equal to zero in said center position and is greatest in the respective end positions upon moving-out and moving-in, respectively, of said cover sheets.
Claim 3
Dependent Claim
65 words
The protective cover, as set forth in claim 1, wherein: always two equal of said energy accumulators are disposed at an angle towards each other between said individual cover sheets and are pivotally connected, on the one hand, at about the center of the upper of said cover sheets and on the end wall of the lower of said cover sheets, on the other hand.
Claim 4
Dependent Claim
31 words
The protective cover, as set forth in claim 2, wherein: said end wall of said cover sheets has a recess within the range of the moving path of said energy accumulators.
Claim 5
Dependent Claim
47 words
The protective cover, as set forth in claim 3, wherein: said energy accumulators disposed at an angle towards each other are pivotally connected to the end wall of said cover sheets closely adjacent each other on a joint console secured below said recess on said end wall.
Claim 6
Dependent Claim
58 words
The protective cover, as set forth in claim 4, wherein: each of said energy accumulators comprises a guide tube with an inserted pressure spring and a plurality of inserted plate springs, respectively, and pull rods inserted from both sides; and said pull rods are pivotally connected by means of eyes below said cover sheet and on said console.
Claim 7
Dependent Claim
34 words
The protective cover, as set forth in claim 4, wherein: each of said energy accumulators comprise a rotary rod pivotally secured below said cover sheet with a rotary rod spring disposed in said console.
Claim 8
Dependent Claim
50 words
The protective cover, as set forth in claim 6, which includes: guide eyes for a longitudinal displacement movement of said rotary rods; and said rotary rod spring is mounted safe against rotation with serrations at the lower end in said console and at its upper end in said rotary rod.
Claim 9
Dependent Claim
19 words
The protective cover, as set forth in claim 4, wherein: each of said energy accumulators comprises a pull spring.

Claim 11
Dependent Claim
19 words
The protective cover, as set forth in claim 4, wherein: each of said energy accumulators comprises an elastic means.
Claim 12
Dependent Claim
37 words
The protective cover, as set forth in claim 10, wherein: said elastic means are secured below said cover sheet, and which includes an eyelet on said end wall; and said elastic means are suspended from said eyelet.
Claim 13
Dependent Claim
45 words
The protective cover, as set forth in claim 10, wherein: said elastic means are secured in the center below said cover sheet closely adjacent to each other and at the end wall at a larger distance from each other at the end of said recess.
Claim 14
Dependent Claim
20 words
The protective cover, as set forth in claim 4, wherein each of said energy accumulators includes at least one spring.
