Abstract
Abstract An apparatus for supporting pipe lines or the like on a supporting structure. The apparatus includes a housing for connection with the supporting structure and a pressure spring in the housing. The spring acts on a spring rest which is coupled with a support element in such a manner that the support element may be rotated to longitudinally adjust the position thereof relative to the spring rest. A preset spring force, corresponding with the pipe load anticipated during use and for offsetting such load, is maintained by a simple blocking device. The blocking device may include a crossbolt selectively connectable with the support element for blocking longitudinal movement of the spring rest. The arrangement of elements is such that, even when the blocking device is effective, the support element may still be rotated to effect further adjustment of the relative position of the spring rest and thus of the preset force of the spring. Also, the blocking device may selectively cooperate with a screw element, attached to the support element, to lock the support element in substantially any relative longitudinal position with respect to the spring housing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
158 words
An apparatus for supporting pipe lines or the like on a supporting structure, the apparatus comprising: (a) a housing for connection with the supporting structure, said housing having a longitudinal axis and an end portion; (b) biasing means with opposite ends, one end of said biasing means being so disposed in said housing as to act against said housing end portion; (c) a spring rest in said housing, said spring rest being coupled with the other end of said biasing means; (d) a support element coupled with said spring rest; (e) means, coupled between said support element and spring rest, for longitudinally adjusting said support element relative to said spring rest in response to rotation of said support element; (f) means, selectively connectable with said support element, for blocking movement of said spring rest relative to said housing in either longitudinal direction without blocking adjusting movement of said spring rest in response to rotation of said support element.
Claim 2
Independent Claim
158 words
An apparatus for supporting pipe lines or the like on a supporting structure, the apparatus comprising: (a) a housing for connection with the supporting structure, said housing having a longitudinal axis and an end portion; (b) biasing means with opposite ends, one end of said biasing means being so disposed in said housing as to act against said housing end portion; (c) a spring rest in said housing, said spring rest being coupled with the other end of said biasing means; (d) a support element coupled with said spring rest; (e) means, coupled between said support element and spring rest, for longitudinally adjusting said support element relative to said spring rest in response to rotation of said support element; (f) means, selectively connectable with said support element, for blocking movement of said spring rest relative to said housing in either longitudinal direction without blocking adjusting movement of said spring rest in response to rotation of said support element.
Claim 3
Dependent Claim
31 words
An apparatus as defined in claim 1, including, means coupled between said housing and support element, for locking said support element in any relative longitudinal position with respect to said housing.
Claim 4
Dependent Claim
52 words
An apparatus as defined in claim 2: (d) wherein said locking means includes a movable element coupled with and movably adjustable relative to said support element; and (b) wherein said blocking means cooperates with said movable element to selectively lock said movable element against relative movement with respect to said support element.
Claim 5
Dependent Claim
20 words
An apparatus as defined in claim 3 wherein said screw element is a threaded sleeve screwed on the support element.
Claim 6
Dependent Claim
34 words
An apparatus as defined in claim 4 wherein: (a) said blocking means includes a crossbolt; and (b) said threaded sleeve may be fixed against longitudinal movement with respect to said housing by said crossbolt.
Claim 7
Dependent Claim
54 words
An apparatus as defined in claim 3 including: (a) a bottom opening in said housing end portion; (b) a rotatable collar axially fixed in said housing, said collar surrounding said support element and extending through said housing end portion, said blocking means selectively providing a rigid connection between said collar and said screw element.
Claim 8
Dependent Claim
60 words
An apparatus as defined in claim 6, wherein: (a) said screw element and said collar are provided with transverse holes; (b) said support element is provided with a hole which is elongated in the direction of said longitudinal axis of said housing; and (c) said blocking means includes a crossbolt which may selectively be passed through all of said holes.
Claim 9
Dependent Claim
23 words
An apparatus as defined in claim 7, wherein plural rows of said transverse holes are arranged in axial succession in said screw element.
Claim 10
Dependent Claim
28 words
An apparatus as defined in claim 6, wherein said support element extends from said housing to the exterior thereof via said bottom opening in said housing end portion.
Claim 11
Dependent Claim
46 words
An apparatus as defined in claim 1: (a) including a top opening in said housing, said top opening being disposed longitudinally opposite and remote from said housing end portion; (b) wherein said support element extends from said housing to the exterior thereof via said top opening.
Claim 12
Dependent Claim
59 words
An apparatus as defined in claim 10: (a) wherein said biasing means is a helical spring and said support element is arranged coaxially with respect to said helical spring, a portion of said support element being disposed within said helical spring; (b) including a guide bearing coupled between said housing end portion and one end of said support element.
Claim 13
Dependent Claim
53 words
An apparatus as defined in claim 3: (a) wherein said movable element is a screw element threadably coupled with and movably adjustable relative to said support element; and (b) wherein said blocking means cooperates with said screw element to selectively lock said screw element against relative rotation with respect to said support element.
