Abstract

Abstract An integral clamp for hydraulic connections, for use in household service and the like, consisting in a hoop which clamps the main piping and to which main piping it is attached by means of fastening devices, wherein the above mentioned hoop includes a normally projected tubular-shaped element which is diametrically split all the way down to the hoop that is also split and in which element interior a coupling sleeve is housed in a fixed position with said sleeve having a curved inferior end that includes a peripherical groove on which a ring-shaped seal of elastomeric material is superposed, which seal is hermetically pressed against the external surface of the main piping by the action of a binding nut, that is, threadedly coupled to the external surface of the projection element, and which binding nut which is ring-shaped is superposed on the above mentioned coupling sleeve and leans on a peripherical protruberance of the coupling sleeve.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 271 words
An integral clamp for hydraulic connections for use in household service and the like, comprising in combination: a. clamp means including a hoop portion having a substantially constant diameter and extending for substantially 360* adapteD to substantially completely encompass and clamp a main tubular member integrally formed with said hoop portion and normally projecting thereform, said tubular member and said hoop portion being diametrically split along the axial length thereof so as to form a resiliently deformable split-ring structure and axially extending guide means being formed on the internal annular surface of said tubular member; b. a tubular coupling sleeve forming a connection with a household piping being fixedly positioned within said tubular member; said coupling sleeve having an axially inner end surface arcuately shaped so as to be coextensive with the inner circumferential surface of said hoop portion; guide means formed on the exterior annular surface of said coupling sleeve cooperatively engaging the guide means on said tubular member so as to position said coupling sleeve in a predetermined angular relationship within said tubular member; and annular groove means in the arcuate inner end of said coupling sleeve; c. ring-shaped seal means positioned in said annular groove means and projecting therefrom radially inwardly of said hoop portion; d. and a ring-shaped binding nut being threadedly engaged on a complementary thread on the external annular surface of said tubular member and adapted to exert a compressive force to said tubular member and said hoop portion so as to clamp the latter about the main piping, said tubular member and coupling sleeve having diameters smaller than the diameter of said hoop portion.
Claim 2
Dependent Claim 271 words
An integral clamp for hydraulic connections for use in household service and the like, comprising in combination: a. clamp means including a hoop portion having a substantially constant diameter and extending for substantially 360* adapteD to substantially completely encompass and clamp a main tubular member integrally formed with said hoop portion and normally projecting thereform, said tubular member and said hoop portion being diametrically split along the axial length thereof so as to form a resiliently deformable split-ring structure and axially extending guide means being formed on the internal annular surface of said tubular member; b. a tubular coupling sleeve forming a connection with a household piping being fixedly positioned within said tubular member; said coupling sleeve having an axially inner end surface arcuately shaped so as to be coextensive with the inner circumferential surface of said hoop portion; guide means formed on the exterior annular surface of said coupling sleeve cooperatively engaging the guide means on said tubular member so as to position said coupling sleeve in a predetermined angular relationship within said tubular member; and annular groove means in the arcuate inner end of said coupling sleeve; c. ring-shaped seal means positioned in said annular groove means and projecting therefrom radially inwardly of said hoop portion; d. and a ring-shaped binding nut being threadedly engaged on a complementary thread on the external annular surface of said tubular member and adapted to exert a compressive force to said tubular member and said hoop portion so as to clamp the latter about the main piping, said tubular member and coupling sleeve having diameters smaller than the diameter of said hoop portion.
Claim 3
Dependent Claim 35 words
A clamp as claimed in claim 1, comprising an internal thread being formed at the upper end of said coupling sleeve adapted to be engaged by a complementary threaded end of a household service piping.
Claim 4
Dependent Claim 32 words
A clamp as claimed in claim 1, comprising an adapter adapted to be fastened to the upper end portion of said coupling sleeve for connecting the latter to a household service piping.
Claim 5
Dependent Claim 20 words
A clamp as claimed in claim 1, said binding nut being annular and including an upper flange and peripheral grooves.
