Abstract
Abstract An anchoring device formed from a single piece of sheet metal for securing a cylindrical stud portion of a drawer pull or the like in a socket in a drawer front. The anchoring device is in the form of a split collet having a cylindrical sleeve portion terminating in outwardly projecting flange segments at one end and inwardly flaring tapered conical segments at the other end providing tooth formations to hold the stud in the sleeve portion following insertion. The sleeve portion includes a pair of inwardly bowing convex anchoring prongs to be driven outwardly into the drawer front material to anchor the sleeve portion in the socket.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
237 words
An anchoring device in the form of a split collet constructed of a single sheet of spring-like material for securing a drawer pull having a cylindrical stud portion in a cylindrical opening of a drawer front or the like, the anchoring device comprising an axially elongated substantially cylindrical sleeve portion to fit within said opening and to receive said stud portion therein, said sleeve portion defining an annular wall having inner and outer ends and a center axis and having a slit extending along the axial length thereof, meanS defining an integral stop shoulder surface projecting outwardly from the outer end of said sleeve portion to abut the front surface of the drawer front and limit insertion of the sleeve portion into the opening, the sleeve portion including bendable anchoring members having abutment portions extending toward said center axis from said wall to be engaged by an axially inserted tool and driven outwardly to extend the anchoring members outwardly from said wall and embed them in the surrounding material of said drawer front, and said sleeve portion having stud gripping formations in the insertion path of the stud portion to be stressed thereby and restrain the stud portion against withdrawal, said slit extending along a zig-zag path having two end portions at said inner and outer ends alined along a radial plane of said center axis and having an intermediate portion circumferentially offset from said end portions.
Claim 2
Dependent Claim
237 words
An anchoring device in the form of a split collet constructed of a single sheet of spring-like material for securing a drawer pull having a cylindrical stud portion in a cylindrical opening of a drawer front or the like, the anchoring device comprising an axially elongated substantially cylindrical sleeve portion to fit within said opening and to receive said stud portion therein, said sleeve portion defining an annular wall having inner and outer ends and a center axis and having a slit extending along the axial length thereof, meanS defining an integral stop shoulder surface projecting outwardly from the outer end of said sleeve portion to abut the front surface of the drawer front and limit insertion of the sleeve portion into the opening, the sleeve portion including bendable anchoring members having abutment portions extending toward said center axis from said wall to be engaged by an axially inserted tool and driven outwardly to extend the anchoring members outwardly from said wall and embed them in the surrounding material of said drawer front, and said sleeve portion having stud gripping formations in the insertion path of the stud portion to be stressed thereby and restrain the stud portion against withdrawal, said slit extending along a zig-zag path having two end portions at said inner and outer ends alined along a radial plane of said center axis and having an intermediate portion circumferentially offset from said end portions.
Claim 3
Dependent Claim
121 words
An anchoring device as defined in claim 1, wherein said anchoring members comprise elongated bendable prongs integral with said wall having a first end bendably joined to the wall near said outer end and a second end forming a narrow free end spaced toward said inner end from said first end, said prongs normally extending along an inwardly convex path from the first and second ends thereof to the longitudinal midportion thereof disposing said midportion at a position to be engaged and forced outwardly by a tool inserted into the encircled space surrounded by said annular wall and thereby drive the part of each anchor prong extending from the midportion to the free end outwardly into the surrounding drawer front material.
Claim 4
Dependent Claim
88 words
An anchoring device as defined in claim 1, wherein said sleeve portion near said inner end includes inwardly tapering, conical segments terminating in concave tooth formations defined by their free edges at said inner end, said conical segments forming said stud gripping formation and being disposed to intercept and be flexed outwardly by parts of said stud portion upon insertion of the latter into the space encircled by the sleeve portion whereupon said tooth formations engage the surface of the stud portion and restrain the same against withdrawal.
Claim 5
Dependent Claim
88 words
An anchoring device as defined in claim 2, wherein said sleeve portion near said inner end includes inwardly tapering, conical segments terminating in concave tooth formations defined by their free edges at said inner end, said conical segments forming said stud gripping formation and being disposed to intercept and be flexed outwardly by parts of said stud portion upon insertion of the latter into the space encircled by the sleeve portion whereupon said tooth formations engage the surface of the stud portion and restrain the same against withdrawal.
Claim 6
Dependent Claim
94 words
An anchoring device as defined in claim 1, wherein said sleeve portion near said inner end includes a pair of diametrically opposite inwardly tapering, conical segments terminating in semi-circular concave tooth formations defined by their free edges at said inner end, said conical segments forming said stud gripping formation and being disposed to intercept and be flexed outwardly by parts of said stud portion upon insertion of the latter into the space encircled by the sleeve portion whereupon said tooth formations engage the surface of the stud portion and restrain the same against withdrawal.
Claim 7
Dependent Claim
94 words
An anchoring device as defined in claim 2, wherein said sleeve portion near said inner end includes a pair of diametrically opposite inwardly tapering, conical segments terminating in semi-circular concave tooth formations defined by their free edges at said inner end, said conical segments forming said stud gripping formation and being disposed to intercept and be flexed outwardly by parts of said stud portion upon insertion of the latter into the space encircled by the sleeve portion whereupon said tooth formations engage the surface of the stud portion and restrain the same against withdrawal.
