Abstract
Abstract In a displaceable, electric distribution device for building sites or similar consisting of a main section holding current distribution equipment, other equipment and/or instruments, the main section (2) is mounted in a rack, which when the device (1) is uninfluenced by outer forces assumes specific positions for use. By means of relatively small outer forces, the device can nevertheless be moved from one position for use to another by rolling the rack (3). The rack (3) can comprise two substantially equal sets of rockers (10a, 10b) arranged parallel to each other on either side of the main section (2). The rockers (10a, 10b) can have a generally oval shape or the shape of an ellipsis. Aside from assuming specific positions for use and allowing rolling of the device, the rack can in overturned position allow for the possibility of stacking several devices on top of each other.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A portable electrical distribution apparatus having a housing containing current distribution equipment and rotatable support frame means having at least one stable rotational position and selectively rotatable for moving said housing, said frame means comprising a pair of parallel frame members spaced from one another on opposite sides of said housing, each frame member having a pair of rounded end sections of predetermined radius of curvature and at least one intermediate section of different shape than said end sections to define said one stable rotational position.
Claim 2
Dependent Claim
86 words
A portable electrical distribution apparatus having a housing containing current distribution equipment and rotatable support frame means having at least one stable rotational position and selectively rotatable for moving said housing, said frame means comprising a pair of parallel frame members spaced from one another on opposite sides of said housing, each frame member having a pair of rounded end sections of predetermined radius of curvature and at least one intermediate section of different shape than said end sections to define said one stable rotational position.
Claim 3
Dependent Claim
18 words
The apparatus according to claim 1 wherein said rounded end sections of said frame members are generally semi-circular.
Claim 4
Dependent Claim
41 words
The apparatus according to claim 2 wherein said end sections are spaced from one another by two opposite sections having a greater radius of curvature than said end sections so that each frame member takes the general form of an ellipse.
Claim 5
Dependent Claim
30 words
The apparatus according to claim 2 wherein said end sections are spaced from one another by two spaced intermediate sections formed by radially inwardly bent portions of the frame members.
Claim 6
Dependent Claim
24 words
The apparatus according to claim 2 wherein said housing has a generally tubular-shaped configuration with a central axis oriented parallel to said frame members.
Claim 7
Dependent Claim
25 words
The apparatus according to claim 2 wherein said housing has a generally tubular shaped configuration with a central axis oriented perpendicular to said frame members.
Claim 8
Dependent Claim
56 words
The apparatus according to claim 2 further comprising means securing the frame members to the main housing such that the respective planes of the frame members lie peripherally beyond the housing and such that the apparatus can be turned over onto one of the frame members and remain stable and allow stacking of other overturned apparatus.
Claim 9
Dependent Claim
15 words
The apparatus according to claim 7 further including means for locking the stacked apparatus together.
Claim 10
Dependent Claim
29 words
The apparatus according to claim 2 further comprising connecting means securing the frame members to the housing, said connecting means including support means onto which cable can be reeled.
Claim 11
Dependent Claim
21 words
The apparatus according to claim 2 wherein said intermediate section has a concave zone defining the stable position for the apparatus.
Claim 12
Dependent Claim
37 words
The apparatus according to claim 2 wherein said end sections are spaced from one another by gaps in said frame members defining two spaced intermediate sections which in turn define two stable rotational positions of said apparatus.
