WAYS OF CARRYING OUT THE INVENTION

(11) According to FIGS. 1 to 3, the device for fastening an end strip 1 comprises a holder which has a wall limb 2 with two leaf-spring-like spreading arms 3 projecting laterally therefrom. As can be seen from FIG. 2, these spreading arms 3 are swung out of the plane of the wall limb 2 and must be swung back against the spring force against the plane of the wall limb 2 to insert the holder into the connection joint 4 between a wall 5 and a flooring 6. After being released, the swivelled back spreading arms 2 rest against the end face 7 of the flooring 6 under elastic pre-tension, as shown in FIG. 3.

(12) With the aid of a stop 8 at the free end of the spreading arms 3 the holder is supported on the flooring 6 in terms of height. With the elastic spreading by the spreading arms 3, the wall limb 2 is held pressed against the wall 5 so that the end strip 1 can be placed on two holding webs 9, which project upwards from the wall limb 2 and engage in a downwardly open groove 10 of the end strip 1 to clamp the end strip 1. The spreading arms 3 can be provided with beads 11 to influence the spring stiffness.

(13) As can be seen in particular from FIGS. 1 and 3, the holder has a wall web 12 punched out of the wall limb 2 and bounded by a bottom edge 13 parallel to the base and two side edges 14 extending therefrom. At a height distance from the bottom edge 13, the wall web 12 is provided with a slope lug 15 projecting from the wall limb 2 for the end strip 1 in the form of a tongue 16 punched out of the wall web 12 and extending from the bottom edge 13 of the wall web 12. If the end strip 1 indicated by a dotted line in FIG. 3 is pushed onto the holding webs 9, the end strip 1 runs onto the slope lug 15, whereby the wall web 12 is pressed against the wall 5 with a force which presses the claws 17 provided on the bottom edge 13 of the wall web 12 and projecting towards the wall 5 into the wall 5 and thus prevents the wall limb 2 from being pulled out of the connection joint 4 along the wall 5.

(14) FIG. 3 shows the holder in the unloaded, relaxed position before the end strip 1 is fitted, so that the displacements of the holding webs 9 on the one hand and the slope lug 15 on the other hand caused by the end strip when the end strip 1 is fitted onto the holding webs 9 can be seen.

(15) To prevent the end strip 1 from being pulled off the holder, the end strip 1 is provided with a latching groove 18 into which latching projections 19 snap. These latching projections 19 can be formed by corresponding bulges of the holding webs 9 and/or by the slope lug 15.

(16) The embodiment according to FIGS. 4 to 6 differs from the embodiment according to FIGS. 1 to 3 essentially only in the shaping of the wall limb 2 to form the wall web 12, which is not punched directly out of the wall limb 2 but out of a wall panel 20 bent out of the wall limb 2. The wall panel 20 punched out of the wall limb 2 is bent out of the wall limb 2 about a lower axis 21, the wall web 12 with the slope lug 15 extending from the upper edge section 22 of the wall panel 20.

(17) If, when the end strip 1 is fitted onto the holding webs 9, the slope lug 15 of the wall web 12 is acted upon and thereby pressed against the wall 5, this action causes, on the one hand, a torque on the wall web 12 around an axis in the region of connection of the wall web 12 to the upper wall section 22 of the wall panel 20 and, on the other hand, a torque on the wall panel 20 around the bending axis 21, whereby a displacement of the bottom edge 13 of the wall web 12 against the wall 5 is ensured which is advantageous for an engagement of the claws 17 with the wall 5.

(18) According to the embodiment of FIGS. 7 to 9, the wall web 12 is again punched out of a wall panel 20, which is bent out of the wall limb 2 of the holder about the axis 21, as in FIGS. 4 to 6. In contrast to FIGS. 4 to 6, however, the upper edge section 22 of the wall panel 20 bent out of the wall limb 2 forms the holding web 9. This circumstance means that the upper edge section 22, which serves as the holding web 9, is bent away from the wall limb 2 when the end strip 1 is fitted, as is usually the case with holding webs 9 due to their orientation relative to the groove 10 of the end strip 1, in order to press the end strip 1 against the wall limb 2 or against the wall 5 under pretension. This additional pivoting movement of the wall panel 20 causes the wall web 12 supported by the wall panel 20 to also pivot with the effect that the impact on the wall web 12 via the slope lug 15 is supported by this superimposed pivoting movement, so that the claws 17 on the bottom edge 13 of the wall web 12 find a secure hold in the wall 5.

(19) The embodiment according to FIGS. 7 to 9 also shows that the snap-fastener-like latching between the holder and the end strip 1 with the aid of latching projections 19 engaging in a latching groove 18 of the end strip 1 can also be achieved only with the aid of bulges formed on the holding webs 9, just as it is also possible to use only the run-on lug 15 as a latching projection.
