Abstract

Abstract A tubular anchoring member having an interior passage is inserted into an anchoring hole of a support structure. The anchoring member has transverse dimensions smaller than those of the anchoring hole so that a clearance is defined therewith. A ring-shaped cap member surrounds the anchoring member at a trailing end thereof, supports the anchoring member, and closes the open end of the clearance. An aperture formed in the anchoring member communicates the interior passage with the clearance. A guide sleeve is inserted into the interior passage until a closed leading end of the sleeve is located in the vicinity of the aperture. An open trailing end of the sleeve is connected to a collapsible envelope which is subdivided into a plurality of compartments, each containing a different component of a multi-component hardenable binder material. The compartments are brought into communication with each other and, in response to collapsing the envelope, the respective components are intermixed and advanced from the collapsible element through the interior of the guide sleeve to be introduced into the clearance via the aperture. The closed leading end of the guide sleeve is opened by either cutting off such leading end from the remainder of the sleeve or by bursting in response to forces generated during the collapse of the envelope. The intermixed components introduced in the clearance harden therein about the anchoring member and thereby anchor the latter in the anchoring hole.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 223 words
An arrangement for securing an object to a support structure having an anchoring hole, comprising a sleeve-shaped anchoring element having one part of transverse dimensions smaller than, and another part of transverse dimensions substantially corresponding to those of the anchoring hole, said anchoring element being insertable into the anchoring hole through an open end thereof so that said other part supports said anchoring element at the open end of the anchoring hole with clearance between the latter and said one part and closes the open end of said clearance upon insertion, said anchoring element having an interior passage; and a closed collapsible container accommodating components of a multi-component hardenable binding material and having a first portion fittingly insertable into said interior passage of said anchoring element and a second portion remaining outside of said anchoring element upon such insertion of the same so that when said first portion of said container is inserted in said interior passage of said anchoring element and said second portion of said container is subjected to requisite collapsing force, the binding material is discharged from said container into said clearance to anchor said anchoring element in the anchoring hole, without thereby filling said interior passage of said anchoring element about said first portion of said container since such filling is prevented by the presence of said first portion.
Claim 2
Dependent Claim 223 words
An arrangement for securing an object to a support structure having an anchoring hole, comprising a sleeve-shaped anchoring element having one part of transverse dimensions smaller than, and another part of transverse dimensions substantially corresponding to those of the anchoring hole, said anchoring element being insertable into the anchoring hole through an open end thereof so that said other part supports said anchoring element at the open end of the anchoring hole with clearance between the latter and said one part and closes the open end of said clearance upon insertion, said anchoring element having an interior passage; and a closed collapsible container accommodating components of a multi-component hardenable binding material and having a first portion fittingly insertable into said interior passage of said anchoring element and a second portion remaining outside of said anchoring element upon such insertion of the same so that when said first portion of said container is inserted in said interior passage of said anchoring element and said second portion of said container is subjected to requisite collapsing force, the binding material is discharged from said container into said clearance to anchor said anchoring element in the anchoring hole, without thereby filling said interior passage of said anchoring element about said first portion of said container since such filling is prevented by the presence of said first portion.
Claim 3
Dependent Claim 34 words
The arrangement of claim 1, wherein said one part is constituted by an anchoring member, and said other part by a ring-shaped cap member surrounding a portion of said anchoring member upon assembly therewith.
Claim 4
Dependent Claim 75 words
The arrangement of claim 2, wherein said anchoring member is generally tubular and has a closed leading end and an open trailing end as viewed in the direction of introduction of said anchoring element into the anchoring hole; and further comprising means for introducing the binding material from said container into the said clearance, said introducing means including at least one aperture in said anchoring member for passage of said components therethrough into said clearance.
Claim 5
Dependent Claim 57 words
The arrangement of claim 1, wherein said second portion of said container is a collapsible envelope having an interior, means for subdividing said interior into a plurality of compartments each containing one of the components of the binding material, and means for effecting communication between said compartments for bringing said respective components into contact with each other.
Claim 6
Dependent Claim 40 words
The arrangement of claim 1, wherein said anchoring member has an internal thread at said trailing end thereof, and wherein said first portion of said container is operative for preventing said components from flowing towards and penetrating into said thread.
Claim 7
Dependent Claim 15 words
The arrangement of claim 4, wherein said collapsible envelope is constituted by thin-walled, yieldable material.
Claim 8
Dependent Claim 25 words
The arrangement of claim 4, wherein said subdividing means includes means for urging opposite wall portions of said collapsible envelope into contact with each other.
Claim 9
Dependent Claim 49 words
The arrangement of claim 7, wherein said urging means comprises a first clamping element having a recess in which said opposite wall portions are receivable, and a second clamping element receivable with snap-type action in said recess for urging said opposite wall portions into friction-tight engagement with each other.
Claim 10
Dependent Claim 30 words
The arrangement of claim 1, wherein said first portion of said container is a sleeve member of transverse dimensions corresponding to those of said interior passage of said anchoring element.
Claim 11
Dependent Claim 47 words
The arrangement of claim 9, wherein said sleeve member has closed leading end and an open trailing end as viewed in the direction of insertion of said sleeve member into said interior passage; and further comprising means for opening said closed leading end of said sleeve member.
