DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0043] A preferred exemplary embodiment is shown in FIGS. 1 to 7. FIG. 1 shows a door having a door frame R and a door leaf F. The door hinge B in this figure is not visible but is covered by the finger protection device S according to the invention. As may be identified in FIG. 1, the finger protection device S extends approximately over the entire height of the door leaf F and thus bridges the gap which is produced between the door frame R and the door leaf F when the door is open.

[0044] In FIGS. 2 and 3 a cross section is shown through a part of FIG. 1, so that the finger protection device S according to the invention may be identified more clearly.

[0045] The finger protection device substantially consists of a roller blind. A shaft 10 is arranged in a roller blind housing 2. A roller blind web 1 is wound onto the shaft 10. The web 1 preferably consists of a textile material. The shaft 10 is spring-loaded so that an unwound part of the web 1 is automatically pulled back. This arrangement is sufficiently known from the prior art.

[0046] The free edge of the web 1 is reinforced by an end strip 11. This may be implemented by thickening the web 1 itself. Generally, however, the edge is connected to a metal or plastic strip. This end strip 11 is in a suspension strip 3 which is configured to be hook-shaped.

[0047] The housing 2 of the roller blind is preferably fastened to the door leaf F. However, it may also be arranged on the door leaf F. A fastening strip 4 as the first fastening means is screwed onto the counterpart of the door, therefore, in this case onto the door frame R. The suspension strip 3 forms a second fastening means which may be suspended in the first fastening means. This is clearly identifiable in FIGS. 2 and 3. Due to the restoring force of the roller blind, in the suspended state the web 1 is tensioned in every position of the door leaf F. It covers the gap in each case between the door frame R and the door leaf F. The web 1, therefore, provides protection from accidents on the side located opposite the hinge B.

[0048] In FIGS. 4 and 5 it is able to be clearly identified how the finger protection device S according to the invention is mounted. Firstly, the housing 2 is fastened by at least one first screw 22 to the door leaf F and subsequently the fastening strip 4 is mounted.

[0049] The housing 2 has a base body 20 in which the shaft 10 and the wound-up web 1 are held. The base plate of the base body 20, by which the housing 2 bears against the door leaf F, is lengthened in a projection 21. This projection 21 is formed by a strip which preferably extends over the entire length of the base body 20. In alternative embodiments, the projection 21 is formed by two or more tabs which extend away from the base body 20. This projection 21 may be fastened by the at least one first screw 22 to the door leaf. Preferably a plurality of first screws 22 are present. As a result, the housing 2 is fixed to the door leaf F. Further fastenings, for example on the side of the base body 20 opposing the projection 21, are not necessary. Depending on the shape and size of the housing 2, however, even more fastenings may be present.

[0050] The first fastening means, in this case the fastening strip 4, is fastened on the opposing side of the finger protection device S, i.e. on the door frame R. This fastening strip 4 preferably also extends approximately over the entire length of the door frame R. The fastening strip is preferably configured, in particular, to be the same length as the housing 2.

[0051] The web 1 is fixedly held by the end strip 11 in the suspension strip 3. To this end, the suspension strip 3 has a base body 30 which has a substantially U-shaped cross section. A first limb 32 of the U-shaped base body 30 forms a suspension hook. A second limb of longer configuration has at its free end a groove 31. This groove is configured as a holder. The opening of the groove 31 is located on the side of the second limb opposing the suspended hook 32 and is oriented outwardly. The groove 31 preferably extends over the entire length of the suspension strip 3. The suspension strip 3 is preferably configured to be of equal length with the fastening strip 4 and the housing 2. At least the suspension strip 3 and the groove 31 are configured to be of equal length with the web 1.

[0052] The end strip 11 is inserted into the groove 31. The end strip is pivotably held therein.

[0053] The fastening strip 4 has a stop plate 40. On a longitudinal side of the stop plate 40, said stop plate transitions integrally into a suspension plate 42. The suspension plate 42 is configured to be thinner than the stop plate 40. The suspension plate 42 has a projection and/or a nose 420 oriented vertically away from the door frame R. On the opposing side of the suspension plate 42, the stop plate 40 transitions integrally into a fastening plate 43. The fastening plate 43 is preferably configured to be thinner than the stop plate 40. The fastening plate preferably has at least one slot 46, preferably a plurality of slots 46. The slots 46 extend in the direction transversely to the longitudinal direction of the fastening strip 4, i.e. in the horizontal direction when the finger protection device S is suspended.

[0054] The fastening strip 4 is fixedly screwed to the door frame R by means of at least one third screw 5. The slots 46 permit in this case a horizontal displacement of the fastening strip 4 without new holes having to be drilled.

[0055] The stop plate 40 bears with its rear face flat against the door frame R. An adhesive mounting strip 45, which is preferably arranged to the rear of the fastening plate 43, simplifies the mounting. The adhesive mounting strip 45 may extend, but does not have to extend, over the entire length of the fastening strip 4. The suspension plate 42 forms an undercut in the suspended state of the fastening strip 4. The suspension hook 32 of the suspension strip 3 engages in this undercut, wherein the suspension strip 3 is able to be suspended at different heights and the angle of the roller blind web 1, therefore, may be easily varied. This is clearly identifiable in FIGS. 6 and 7. In the suspended state, the front planar surface of the stop plate 40 bears against the inner face of the second limb of the suspension strip 3. The nose 420 also bears against this inner face so that wobbling is prevented.

[0056] The suspended suspension strip 3 may be fixed in its vertical position by means of one or more second screws 33. The at least one second screw 33 is preferably a setscrew which is pressed onto the suspension plate 42 by the second limb of the fastening strip 3.

[0057] The web 1 may be unhooked easily by this second screw 33 being slightly released.

[0058] As may be clearly identified in FIG. 3, in the suspended state the web 1 covers the projection 21 with the first screw 22 and also the fastening plate 43 with the third screw 5. Since the web 1 is not able to be unhooked easily without releasing the second screw 33, the fastening screws 22 and 5 are well protected from tampering.

[0059] If the web 1 is unhooked, however, these screws 22, 5 are easily accessible and a re-adjustment of the finger protection device in the already suspended state may be carried out in a simple manner.

[0060] It is particularly advantageous if the adjustment takes place in the horizontal X-direction and the vertical Y-direction by separate means. As already mentioned above, due to the slots 46 the fastening strip 3 may be displaced in the horizontal direction. Due to the suspension strip 3 which is displaceable in the vertical Y-direction, it is possible for the alignment of the web 1 to be optimally adjusted. It is also advantageous that this vertical adjustment is able to take place even when the door leaf is repeatedly opened and closed, in order to find the optimal position. For the fixing, as mentioned above on both sides, only the at least one second screw 33 has to be screwed in.

[0061] The finger protection device according to the invention is thus of robust construction, it consists of the simplest means and nevertheless allows optimal protection against tampering and a maximum degree of re-adjustability. Moreover, it has an attractive design.
