Abstract
Abstract A mounting element is anchored in a hole of a support structure by use of a hardenable binder material. The latter is fed from a feeding device which has an outlet section insertable into the hole. The outlet section of the feeding device has a volume which corresponds to that of parts of the mounting element to be inserted into the hole. Thereby only enough binder material can enter the hole to anchor the mounting element so that the expulsion of excess binder material from the hole upon introduction of the mounting element is prevented. A ring-shaped member may be fitted onto the mounting element to center and fix the latter in the hole. The ring-shaped member may be inserted into the hole before or after injecting the hardenable binder material into the latter.

Total Claims: 11
Claim 1
Independent Claim
178 words
In an arrangement for anchoring a mounting element in a hole of a support structure by use of a hardenable binding material, a combination comprising a feeding device having an outlet section which is insertable into the hole of the support structure so as to introduce the hardenable binder material into the latter, and thereafter withdrawable from the hole; and a mounting element having a portion which is insertable into the hole after withdrawing said outlet section of said feeding device from the hole, so as to be anchored in the hole when the binding material is hardened in the latter, said insertable portion of said mounting element having a predetermined volume, and said insertable outlet section of said feeding device having a volume which corresponds to the volume of said insertable portion of said mounting element so that due to the presence of said insertable portion only enough binder material can enter the hole to anchor the mounting element, whereby the expulsion of excess binder material from the hole upon introduction of said mounting element is prevented.
Claim 2
Dependent Claim
178 words
In an arrangement for anchoring a mounting element in a hole of a support structure by use of a hardenable binding material, a combination comprising a feeding device having an outlet section which is insertable into the hole of the support structure so as to introduce the hardenable binder material into the latter, and thereafter withdrawable from the hole; and a mounting element having a portion which is insertable into the hole after withdrawing said outlet section of said feeding device from the hole, so as to be anchored in the hole when the binding material is hardened in the latter, said insertable portion of said mounting element having a predetermined volume, and said insertable outlet section of said feeding device having a volume which corresponds to the volume of said insertable portion of said mounting element so that due to the presence of said insertable portion only enough binder material can enter the hole to anchor the mounting element, whereby the expulsion of excess binder material from the hole upon introduction of said mounting element is prevented.
Claim 3
Dependent Claim
16 words
A combination as defined in claim 1, wherein said outlet section is formed as a mouthpiece.
Claim 4
Dependent Claim
84 words
A combination as defined in claim 1, wherein said insertable portion of said mounting element includes a body section, and a ring-shaped section fitted on said body section and insertable into the hole together with said body section after introducing the hardenable binding material into the hole, said ring-shaped section being arranged for centering and fixing said mounting element in the hole, said outlet section of said feeding device having a volume corresponding to that of said body section together with said ring-shaped section.
Claim 5
Dependent Claim
31 words
A combination as defined in claim 3, wherein the hole has a predetermined diameter, said outlet section of said feeding device having a diameter corresponding to the diameter of the hole.
Claim 6
Dependent Claim
81 words
A combination as defined in claim 1; and further comprising a ring-shaped member insertable into the hole prior to introducing the hardenable binding material into the latter, said ring-shaped member having a through opening through which said outlet portion of said feeding device extends into the hole to introduce the hardenable binding material into the latter and through which, after withdrawing said feeding device, said mounting element extends into the hole so as to be centered and fixed in the latter.
Claim 7
Dependent Claim
34 words
A combination as defined in claim 5, said opening of said ring-shaped member has a predetermined diameter, said outlet section of said injecting device having a diameter corresponding to the diameter of said opening.
Claim 8
Dependent Claim
28 words
A combination as defined in claim 1, wherein said outlet section of said feeding device has an outer circumferential surface and a ventilating groove formed in said surface.
Claim 9
Dependent Claim
30 words
A combination as defined in claim 7, wherein said outlet section of said feeding device is elongated, said ventilating groove extending in the direction of elongation of said outlet section.
Claim 10
Dependent Claim
145 words
In an arrangement for anchoring a mounting element in a hole of a support structure by use of a hardenable binding material, a combination comprising a feeding device having an outlet section insertable into the hole for introducing the hardenable binding material into the latter, and thereafter withdrawable from the hole; the mounting element partially insertable into the mounting hole after withdrawing said outlet section of said feeding device from the latter, so as to be anchored in the hole when the binding material is hardened; and a ring-shaped member also insertable into the hole so as to close the latter and, at the same time, to center and fix said mounting element in the hole, said insertable outlet section of said feeding device having a volume corresponding to the volume of parts which are inserted into the hole after introducing the binding material thereinto.
