Abstract
A device for handling a group of cables running to medical x-ray equipment that is movable in all degrees of freedom comprises: A vertical axle mounted overhead; a boom swingable in a horizontal plane on the axle; a housing on the axle having openings for receiving and clamping the ends of respective flexible cable enclosing tubes, one of which extends over the boom to the equipment and the other of which establishes a cable path continuing to a swivel mechanism that is spaced from the axle and mounted overhead.
Claims6
A device for handling a group of cables which extend in a room to and from movable x-ray equipment which is located in the room, said cable handling device comprising:
- axle means mounted above said equipment and a generally horizontally extending boom arm for supporting said cable group, said boom arm comprising two channel members one of which is fastened to said axle means and the other of which is fastened in complementary relation to said one channel member to define a duct for swinging about a vertical axis and for supporting a portion of said cable group passing through said duct generally horizontally with another continuous portion of said cable group extending beyond the support of said boom arm being directed generally downwardly to said x-ray equipment,
- clamping means surrounding said boom arm duct and supported from said axle means, and
- a flexible tubular enclosure through which said cable group runs, said tubular enclosure having an upper end portion surrounding said boom arm and engaged by said clamping means and being swingable with said boom arm and having a lower end portion coupled to said x-ray equipment,
- a swivel mechanism having a passageway for enabling said group of cables to run generally vertically and then to become generally horizontal on said boom arm, said swivel mechanism being rotatable about an axis spaced from the axis of said axle means, and
- a flexible tubular enclosure surrounding the cable portion between said swivel mechanism and said boom arm and having one end fastened to said boom arm and an opposite end fastened to said swivel mechanism to enable relieving the twist which would be otherwise imparted to said tubular enclosure by swinging of said boom arm.

A device for handling a group of cables which extend in a room to and from x-ray equipment, said equipment including:
- An L-arm comprised of unitary vertical and horizontal sections, the horizontal section being supported on one end for enabling said section to rotate about a vertical axis in a horizontal plane;
- a U-arm comprising a base section mounted on said vertical section of the L-arm for rotation in vertical planes about a horizontal axis and a pair of radially spaced apart arm sections projecting from said base section;
- and, x-ray imaging and x-ray source means mounted on said spaced apart arm sections, respectively, said cable handling device comprising:
- axle means mounted above said equipment and generally horizontally extending boom arm means for supporting said cable group, said boom arm means comprising two channel members one of which is fastened to said axle means and the other of which is fastened to said one channel member to define a duct for swinging about a vertical axis and for supporting a portion of said cable group passing through said duct generally horizontally with another continuous portion of said cable group extending beyond the support of said boom means being directed generally downwardly to said x-ray equipment,
- clamping means surrounding said boom arm duct and supported from said axle means, and
- a flexible tubular enclosure surrounding said boom arm means and the portion of the group of cables running on said means and surrounding the portion of said group of cables extending between said boom arm means and said x-ray equipment,
- a swivel mechanism having a passageway for enabling said group of cables to run generally vertically and then to become generally horizontal on said boom arm means, said swivel mechanism being rotatable about a vertical axis in parallel spaced relationship with the axis of said axle means, and
- a flexible tubular enclosure surrounding the cable portion between said swivel means and said boom arm means and having one end fastened to said boom arm means and an opposite end fastened to said swivel means to enable relieving the twist which would otherwise imparted to said tubular enclosure by swinging of said boom arm means.

A device for handling a group of cables which extend in a room to and from x-ray equipment, said equipment including:
- An L-arm comprised of unitary vertical and horizontal sections, the horizontal section being supported on one end for enabling said section to rotate about a vertical axis in a horizontal plane;
- a U-arm comprising a base section mounted on said vertical section of the L-arm for rotation in vertical planes about a horizontal axis and a pair of radially spaced apart arm sections projecting from said base section;
- and, x-ray imaging and x-ray source means mounted on said spaced apart arm sections, respectively, said cable handling device comprising:
- axle means mounted above said equipment and generally horizontally extending boom arm means for supporting said cable group, said boom arm means being mounted to said axle means for swinging about a vertical axis and for supporting a portion of said cable group generally horizontally with another continuous portion of said cable group extending beyond the support of said boom arm means being disposed downwardly for coupling to said x-ray equipment,
- a swivel mechanism having a passageway for enabling said group of cables to run generally vertically and then to become generally horizontal on said boom arm means, said swivel mechanism being rotatable about an axis that is spaced from the axis of said axle means,
- a first flexible tubular enclosure surrounding the cable portion between said swivel means and said boom arm means and having one end fastened to said boom arm means and an opposite end fastened to said swivel means to enable relieving the twist which would be otherwise imparted to said tubular enclosure by swinging of said boom arm means, and
- a second flexible tubular enclosure surrounding the portion of the group of cables extending between said boom arm means and said x-ray equipment.
