Abstract
Abstract An anchoring track designed to be embedded in the surface of a structural member of concrete, the track having a C-shaped profile and a styrofoam filler body filling out the interior of the track to prevent the penetration of mortar into the track, the filler body being removable from the embedded track by means of a tear strip which is arranged between the back side of the filler body and the base wall of the anchoring track, in alignment with the slot of the anchoring track. The tear strip, when pulled through the slot of the track, tears out a central profile portion from the filler body to permit easy removal of the profile portions of the filler body remaining underneath the flange portions of the anchoring track.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
209 words
An anchoring track adapted to be embedded in the surface of a structural member of cast concrete or a comparable mortar-cast material for the suspension thereon and/or attachment thereto, in a fixed or longitudinally displaceable relationship, of a object with the aid of at least one anchoring member which is received in the anchoring track behind oppositely facing flange portions of the track profile, the anchoring track comprising in combination: an anchoring track body in the form of a continuous profile defining a generally C-shaped cross section, said oppositely facing flange portions flanking a central longitudinal slot facing away from the surrounding surface of the structural member; a filler body received inside the anchoring track profile, the cross section of the filler body matching the interior cross section of the anchoring track profile, so as to fill out the latter and to close off both extremities of the anchoring track profile against the penetration of mortar during the embedding operation; and means for tearing a central profile portion of the filler body out of the anchoring track, through the longitudinal slot of the track profile, so as to permit removal of the remaining profile portions of the filler body from behind the flange portions of the embedded anchoring track.
Claim 2
Dependent Claim
209 words
An anchoring track adapted to be embedded in the surface of a structural member of cast concrete or a comparable mortar-cast material for the suspension thereon and/or attachment thereto, in a fixed or longitudinally displaceable relationship, of a object with the aid of at least one anchoring member which is received in the anchoring track behind oppositely facing flange portions of the track profile, the anchoring track comprising in combination: an anchoring track body in the form of a continuous profile defining a generally C-shaped cross section, said oppositely facing flange portions flanking a central longitudinal slot facing away from the surrounding surface of the structural member; a filler body received inside the anchoring track profile, the cross section of the filler body matching the interior cross section of the anchoring track profile, so as to fill out the latter and to close off both extremities of the anchoring track profile against the penetration of mortar during the embedding operation; and means for tearing a central profile portion of the filler body out of the anchoring track, through the longitudinal slot of the track profile, so as to permit removal of the remaining profile portions of the filler body from behind the flange portions of the embedded anchoring track.
Claim 3
Dependent Claim
17 words
An anchoring track as defined in claim 1, wherein the filler body is a one-piece styrofoam body.
Claim 4
Dependent Claim
78 words
An anchoring track as defined in claim 1, wherein the anchoring track profile includes a base wall portion and two side wall portions linking the base wall portion with the two flange portions; and the tearing means is in the form of a tear strip which is received inside the anchoring track profile and confined between said base wall portion and the filler body, the tear strip having a graspable portion which protrudes from the embedded anchoring track.
Claim 5
Dependent Claim
44 words
An anchoring track as defined in claim 3, wherein the graspable portion of the tear strip is an end portion thereof which is folded over an axial extremity of the filler body so as to remain exposed, after the anchoring track has been embedded.
Claim 6
Dependent Claim
66 words
An anchoring track as defined in claim 3, wherein the filler body is constituted of at least two separate filler body lengths adjoining each other longitudinally inside the anchoring track profile; and the graspable portion of the tear strip is a loop portion thereof which protrudes outwardly between the longitudinally adjoining filler body lengths so as to remain exposed, after the anchoring track has been embedded.
Claim 7
Dependent Claim
52 words
An anchoring track as defined in claim 3, wherein the width of the tear strip is approximately the same as the width of the longitudinal slot of the anchoring track, being transversely aligned with the edges of the slot so as to tear the filler body along two substantially parallel separation planes.
Claim 8
Dependent Claim
20 words
An anchoring track as defined in claim 3, wherein the tear strip is an adhesive-backed tape with tensile reinforcing strands.
Claim 9
Dependent Claim
54 words
An anchoring track as defined in claim 3, wherein the filler body is a continuous length of foamed material which is insertable into the anchoring track in an axial direction; and the tear strip is an adhesive-backed tape which is attachable to the filler body, prior to its insertion into the anchoring track profile.
Claim 10
Dependent Claim
24 words
An anchoring track as defined in claim 1, wherein the filler body has longitudinal incisions facilitating the tearing out of said central profile portion.
Claim 11
Dependent Claim
94 words
An anchoring track as defined in claim 1, wherein the flange portions of the anchoring track profile are inclined towards the inside of the anchoring track, so that their longitudinal edges are recessed inwardly from the outer contour of the track cross section; the filler body includes a longitudinal ridge protruding through the longitudinal slot of the anchoring track profile into approximate alignment with a tangent to the outer cross-sectional contour of the anchoring track profile; and the filler body has two longitudinal notches accommodating the inwardly recessed longitudinal edges of the flange portions.
Claim 12
Dependent Claim
34 words
An anchoring track as defined in claim 10, wherein the longitudinal notches of the filler body define incisions in the form of sharp bottom corners facilitating the tearing out of said central profile portion.
Claim 13
Dependent Claim
50 words
An anchoring track as defined in claim 10, wherein the width of the longitudinal ridge of the filler body is slightly larger than the width of the longitudinal slot of the anchoring track profile, so a to produce an interference fit between the filler body and the anchoring track body.
