Abstract
Abstract A pipe clamp comprising two clamp segments mounted at an attachment component, these clamp segments can be detachably connected with one another when assuming their closed position. The clamp segments are anchored at the attachment component by means of a respective hinge disposed between their end sections. At the ends of the clamp sections which face away from the attachment component, these clamp segment-ends possess cooperating parts of a locking means for releasably connecting such clamp segments with one another.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
178 words
A pipe clamp for clamping a pipe comprising: an essentially rigid attachment component including a pair of essentially rigid protruding arms with end portions terminating at respective hinge means; a pair of clamp segments capable of being releasably interconnected with one another carried by said protruding arms; each clamp segment having upper, lower and intermediate sections; hinge means positioned between said end portion of each protruding arm and said intermediate section of said clamp segment for pivoting said clamp segment with respect to said protruding arm when said lower section of said clamp segment is engaged by said pipe being clamped; said upper section of each clamp segment which faces away from the attachment component having its end provided with a locking part cooperating with the locking part at the end of the other clamp segment; said cooperating locking parts providing locking means for releasably interconnecting said clamp segments, said locking means being automatically actuatable by the insertion of said pipe into said clamp segments whereby said inserted pipe is engaged in secured relationship within said clamp segments.
Claim 2
Dependent Claim
178 words
A pipe clamp for clamping a pipe comprising: an essentially rigid attachment component including a pair of essentially rigid protruding arms with end portions terminating at respective hinge means; a pair of clamp segments capable of being releasably interconnected with one another carried by said protruding arms; each clamp segment having upper, lower and intermediate sections; hinge means positioned between said end portion of each protruding arm and said intermediate section of said clamp segment for pivoting said clamp segment with respect to said protruding arm when said lower section of said clamp segment is engaged by said pipe being clamped; said upper section of each clamp segment which faces away from the attachment component having its end provided with a locking part cooperating with the locking part at the end of the other clamp segment; said cooperating locking parts providing locking means for releasably interconnecting said clamp segments, said locking means being automatically actuatable by the insertion of said pipe into said clamp segments whereby said inserted pipe is engaged in secured relationship within said clamp segments.
Claim 3
Dependent Claim
15 words
The pipe clamp as defined in claim 1, wherein: said locking means comprises snap-closure means.
Claim 4
Dependent Claim
38 words
The pipe clamp as defined in claim 1, wherein: the locking part of at least one of the segments comprises a hook-like locking part; said other clamp segment having a recess into which engages said hook-like locking part.
Claim 5
Dependent Claim
27 words
The pipe clamp as defined in claim 1, wherein: the locking part of each segment comprises a respective hook-like locking part which mutually engage with one another.
Claim 6
Dependent Claim
46 words
The pipe clamp as defined in claim 1, wherein: said attachment component and said clamp segments are formed of one-piece from plastic; said attachment component and said one-piece clamp segments being interconnected with one another at a respective hinge groove each defining one of said hinges.
Claim 7
Dependent Claim
43 words
The pipe clamp as defined in claim 5, wherein: each of said clamp segments has a section which extends from its hinge groove to said locking part which is less elastic than another section of such clamping segment which confronts the attachment component.
Claim 8
Dependent Claim
49 words
The pipe clamp as defined in claim 5, wherein: said attachment component comprises a base plate having opposite ends at which there is supported an associated one of said clamp segments; each end of said base plate having an arm extending towards the hinge of the related clamp segment.
Claim 9
Dependent Claim
78 words
The pipe clamp as defined in claim 7, wherein: said base plate includes a contact surface; said base plate further comprising a transverse slot extending substantially parallel to said contact surface and serving for the reception of a plate-shaped threaded nut; and said base plate having an upper surface and provided with a continuous recess at the region of said transverse slot, said continuous recess extending between such contact surface and the upper surface of said base plate.
Claim 10
Dependent Claim
30 words
The pipe clamp as defined in claim 1, wherein: said hinges are dispositioned to coact with said rigid attachment component such that the spacing between the hinges remains essentially constant.
