| 摘要 | An eccentrically locking apparatus holder for attachment of a body thereof about a pipe, said apparatus having first and second flanges, a cam surface, and a rotatable eccentric bushing for movement of the bushing along the cam surface for urging the flanges toward one another and forcibly clamping the body about the pipe. At least one holding member is fixedly attached to the body for maintaining associated apparatus positioned relative to the pipe. | ||||||
| 权利要求 | 1. An eccentric locking apparatus holder for attaching secondary apparatus to a pipe, comprising: a body having an axis, an opening extending coaxially therethrough, inner and outer walls, a longitudinal opening extending through the body walls over the length of said body, and first and second spaced-apart flanges each having first and second end portions and each being positioned on an opposed side of the opening and extending along the length of the body, each end portion of the flanges having a linkage opening extending therethrough with the linkage openings of the first flange being aligned with the linkage openings of the second flange; first and second linkage members each having first and second end portions, a retaining pin opening formed through each end portion and being removably positioned through associated linkage openings of the flanges; first and second retaining pins each being mounted through the retaining pin openings of their respective portion of the linkage members; at least one eccentric locking element positioned on the first retaining pin at a location between the first portions of the first and second linkage members; a cam element positioned on an outer surface of the first flange adjacent each of the eccentric locking elements for receiving said locking element; a handle connected to the eccentric locking element for rotating said element, moving said element along the cam element, linearly moving the flanges relative one to the other, and changing the diameter of the body opening in response thereto; and at least one apparatus holding member being attached to the body and extending outwardly therefrom. 1. An eccentric locking apparatus holder for attaching secondary apparatus to a pipe, comprising: a body having an axis, an opening extending coaxially therethrough, inner and outer walls, a longitudinal opening extending through the body walls over the length of said body, and first and second spaced-apart flanges each having first and second end portions and each being positioned on an opposed side of the opening and extending along the length of the body, each end portion of the flanges having a linkage opening extending therethrough with the linkage openings of the first flange being aligned with the linkage openings of the second flange; first and second linkage members each having first and second end portions, a retaining pin opening formed through each end portion and being removably positioned through associated linkage openings of the flanges; first and second retaining pins each being mounted through the retaining pin openings of their respective portion of the linkage members; at least one eccentric locking element positioned on the first retaining pin at a location between the first portions of the first and second linkage members; a cam element positioned on an outer surface of the first flange adjacent each of the eccentric locking elements for receiving said locking element; a handle connected to the eccentric locking element for rotating said element, moving said element along the cam element, linearly moving the flanges relative one to the other, and changing the diameter of the body opening in response thereto; and at least one apparatus holding member being attached to the body and extending outwardly therefrom. 2. An apparatus, as set forth in claim 1, including a removable retaining pin liner positioned about the second retaining pin in contact with the second flange and the pin along substantially the entire length between the first and second linkage members. 3. An apparatus, as set forth in claim 1, wherein the cam element has a surface of a configuration for receiving the associated locking element and being in contact with the eccentric locking bushing over an arc greater than about 45* in said received position. 4. An apparatus, as set forth in claim 1, wherein the inner wall of the body has protrusions formed thereon. 5. An apparatus, as set forth in claim 1, wherein the handle, in the position wherein the flanges are urged toward one another, is immediately adjacent the outer wall of the body. 6. An apparatus, as set forth in claim 1, wherein each of the flange surfaces that are adjacent one another are tapered across the width of the flange in a direction away from the associated flange for providing a space between the flanges that is progressively larger in a direction from the opening of the body outwardly therefrom. 7. An apparatus, as set forth in claim 1, wherein the holding member has a plurality of clamps attached thereto for maintaining a plurality of second conduits positioned relative to the eccentric locking apparatus holder and its associated pipe. 8. An apparatus, as set forth in claim 1, wherein there are two eccentric locking elements with associated cam elements each positioned adjacent one of the linkage members. 9. An apparatus, as set forth in claim 8, wherein the handle is positioned between said locking elements. |
