Abstract
Abstract A connecting element for the detachable connecting of two frame components, which, within a casing, has at least one retaining element, with which the connecting element and also the frame profile can be connected in a detachable manner with the support profile. Within the casing, an eccentric cam is rotatably positioned to conduct the retaining element in a longitudinally movable manner in the casing so that a component of the retaining element projecting out of the frontal side of the casing can be brought into engagement with an undercut longitudinal groove of the support profile. In the discharge position of the retaining element, the eccentric cam head of the eccentric cam can be pressed into the casing against the force of a spring to be engaged in a boring of a frame profile. A safety mechanism prevents, in the insertion position of the retaining element, the axial movability of the eccentric cam. In order to prevent an unintentional pressing in of the eccentric cam, it is provided that the safety mechanism consists of a projection provided on the eccentric cam, and a recess is constructed in the casing. The projection and the recess are positioned to one another in such a manner that the projection, in the discharge position, can be pressed into the recess, and thereby permit an axial movability of the eccentric cam, but, in the insertion position, can not be pressed in, so that the eccentric cam is thereby prevented from having any axial movability.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
280 words
A connecting element (1) for detachably connecting two frame components, particularly a support profile and a frame profile, the connecting element (1) being positioned in a stationary manner in the frame profile and constructed with a hollow profile, said connecting element having a casing (2) with at least one retaining element (3) therein and being connected with the support profile in a detachable manner, an eccentric cam (14) being positioned within the casing in a pivotable manner, said eccentric cam having at least one eccentric head (15), one eccentric cam disk and one support stud (18), said retaining element (3) being actuated in a longitudinally movable manner in the casing (2) by said eccentric cam, in which a component of the retaining element (3) projecting out of a frontal side of the casing (2) can be brought into contact with an undercut longitudinal groove of the support profile, said eccentric head (15) of the eccentric cam (14) being axially movable into the casing (2) against a spring (24), a safety mechanism preventing axial movement of the eccentric cam (14) during the longitudinal actuation of the retaining element (3), wherein said safety mechanism comprises a projection (22) provided on on the support stud (18) of the eccentric cam (14), and a recess (23) provided in the casing (2), whereby the projection (22) and the recess (23) are aligned with one another in such a manner that the projection (22) may be pressed into the recess, and thereby permitting axial movement of the eccentric cam (14), and when the projection and the recess are misaligned, the eccentric cam is thereby prevented from axial movement during the longitudinal actuation of the retaining element.
Claim 2
Dependent Claim
280 words
A connecting element (1) for detachably connecting two frame components, particularly a support profile and a frame profile, the connecting element (1) being positioned in a stationary manner in the frame profile and constructed with a hollow profile, said connecting element having a casing (2) with at least one retaining element (3) therein and being connected with the support profile in a detachable manner, an eccentric cam (14) being positioned within the casing in a pivotable manner, said eccentric cam having at least one eccentric head (15), one eccentric cam disk and one support stud (18), said retaining element (3) being actuated in a longitudinally movable manner in the casing (2) by said eccentric cam, in which a component of the retaining element (3) projecting out of a frontal side of the casing (2) can be brought into contact with an undercut longitudinal groove of the support profile, said eccentric head (15) of the eccentric cam (14) being axially movable into the casing (2) against a spring (24), a safety mechanism preventing axial movement of the eccentric cam (14) during the longitudinal actuation of the retaining element (3), wherein said safety mechanism comprises a projection (22) provided on on the support stud (18) of the eccentric cam (14), and a recess (23) provided in the casing (2), whereby the projection (22) and the recess (23) are aligned with one another in such a manner that the projection (22) may be pressed into the recess, and thereby permitting axial movement of the eccentric cam (14), and when the projection and the recess are misaligned, the eccentric cam is thereby prevented from axial movement during the longitudinal actuation of the retaining element.
Claim 3
Dependent Claim
23 words
A connecting element in accordance with claim 1, wherein the support stud (18) and the projection (22) are constructed in a single piece.
Claim 4
Dependent Claim
23 words
A connecting element in accordance with claim 2, wherein the projection (22) is a bolt or pin attached to the support stud (18).
Claim 5
Dependent Claim
15 words
A connecting element in accordance with claim 2, wherein the projection (22) has a bevelling.
Claim 6
Dependent Claim
28 words
A connecting element in accordance with claim 1, wherein the recess (23) tightly borders on a guide (21) of the support stud (18) of the eccentric cam (14).
Claim 7
Dependent Claim
42 words
A connecting element in accordance with claim 5, wherein the guide (21) of the support stud (18) is constructed as a boring (20) in the casing base (7), an edge area of which projects into the casing (2) in a crater-shaped manner.
Claim 8
Dependent Claim
53 words
A connecting element in accordance with claim 6, wherein the projection (22) on the support stud (18) is positioned in such a manner that, in a position preventing the pressing in of the eccentric cam (14), it touches a lower edge of the crater-shaped boring (20) or has only a minimal distance therefrom.
Claim 9
Dependent Claim
23 words
A connecting element in accordance with claim 6, wherein the recess (23) extends into a casing base (7) proceeding from the boring (20).
Claim 10
Dependent Claim
29 words
A connecting element in accordance with claim 1, wherein the recess (23) is so dimensioned, that it is somewhat larger than the projection (22) on the support stud (18).
Claim 11
Dependent Claim
26 words
A connecting element in accordance with claim 1, wherein the recess (23) encloses a greater angular section than corresponding to the dimensions of the projection (22).
Claim 12
Dependent Claim
26 words
A connecting element in accordance with claim 1, wherein its casing body (6) consists of cast metal, and its casing base (7) consists of sheet steel.
