DESCRIPTION OF PREFERRED EMBODIMENTS

[0037] FIG. 1 illustrates the basic principle of a finger guard device, the principle also forming the basis for the device according to the invention. FIG. 1 shows a door with a door frame R and a door leaf F. In this figure, the door hinge is not visible. As can be seen in FIG. 1, the finger guard device S extends approximately over the entire height of the door leaf F and thus bridges the gap arising between door frame R and door leaf F when the door is open.

[0038] An embodiment of a finger guard device can readily be seen in FIG. 2. Said finger guard device substantially consists of a roller blind. A shaft 21 is arranged in a roller blind housing 1. A roller blind web 2 is wound on the shaft 21. The roller blind web 2 is preferably composed of a textile material. The shaft 21 is spring-loaded, and therefore an unwound part of the roller blind web 2 is automatically retracted.

[0039] The free end of the roller blind web 2 is reinforced with an end strip 20. Said end strip can be formed by thickening the roller blind web 2 or by a wire. Usually, however, the free edge of the roller blind web 2 is connected to a metal or plastic strip. Said end strip 20 is held in a hanging profile 3 which is of hook-shaped design.

[0040] The roller blind housing 1 of the roller blind is usually fastened to the door frame R. For this purpose, a fastening strip 10 is attached to the roller blind housing 1 or is connected in one piece thereto. A mounting profile 4 is screwed to the counterpart of the door, i.e. here to the door frame R. The fastening screws are provided with the reference sign 5 in the figures.

[0041] The hanging profile 3 is hung in the mounting profile 4 for the fastening of the roller blind. Due to the resetting force of the roller blind, in the hung state the roller blind web 2 is tensioned in every position of the door leaf F. Said roller blind web always covers the gap between door frame R and door leaf F.

[0042] The inventive embodiments according to FIGS. 3 to 8 use the same basic principle. In a first inventive embodiment according to FIGS. 3 and 5 to 7, instead of the mounting profile 4 being flat, as per FIG. 2, a mounting profile 4 is, however, now designed as an angular profile. It is preferably formed in one piece and is preferably manufactured from metal or a plastic. It preferably extends over the entire width of the roller blind web 2, i.e. over approximately the entire height of the door leaf F.

[0043] The roller blind housing 1 and the hanging profile 3 can be formed identically as in the embodiment according to FIG. 2. The roller blind web 2 is held with its end strip 20 fixed in the hanging profile 3. For this purpose, the hanging profile 3 has a main body which has a substantially U-shaped cross section. A first leg of the U-shaped main body forms a hanging hook. A second leg of longer design has a groove 31 at its free end. Said groove is in the form of a support. The opening of the groove 31 is located on the side of the second leg opposite the hung hook, and is directed toward the roller blind housing 1. The groove 31 preferably extends over the entire length of the hanging profile 3. The hanging profile 3 is preferably the same length as the mounting profile 4 and as the roller blind housing 1. At least the hanging profile 3 and the groove 31 are the same length as the roller blind web 2. The end strip 20 is introduced into the groove 31 of the hanging profile 3. Said end strip is held pivotably therein.

[0044] According to the invention, the mounting profile 4 is designed differently than in the embodiment according to FIG. 2. It has an angular profile. As can readily be seen in FIG. 5, it has a supporting leg 40 by which the mounting profile 4 lies against the door leaf, and is fastened to the door leaf F by means of screws 5 or other fastening means, e.g. by adhesive bonding. The supporting surface 400 by which the supporting leg 40 lies against the surface of the door leaf F can be seen in FIGS. 6 and 7.

[0045] The mounting profile 4 merges from the supporting leg 40 into a connecting leg 41 and from there into a fastening leg 42. The fastening leg 42 projects outward to the supporting leg 40, i.e. away from the door leaf surface. It preferably runs at least approximately at right angles to the supporting leg 40. The connecting leg 41 runs obliquely to the two remaining legs 40, 42 and therefore preferably forms an angle of greater than 90. The angle is preferably approximately 135.

[0046] The supporting leg 40 can be formed, for example, with plane-parallel surfaces, or it can have decorations and/or mounting aids, such as, for example, one or more grooves or slots 401, for example on the side facing outward away from the door leaf F. Said grooves or flutes preferably run in the longitudinal direction of the mounting profile 4.

[0047] The mounting profile 4 is formed with a constant cross section over its entire length. It is preferably an extruded profile. The supporting leg 40 and the connecting leg 41 are preferably identical in thickness. The fastening leg 42 is preferably thicker and tapers toward its free end. The fastening leg tapers here via two mutually opposite steps which are, however, arranged offset with respect to each other. The tapered part of the fastening profile 42 forms a hook receptacle 43 for the fastening means of the roller blind web 2, i.e. for the hanging profile 3.

[0048] As can readily be seen in FIG. 5, the hanging profile 43 lies with its second leg against a first stop surface 420 of the thicker part of the fastening leg 42. The stop surface 420 is indicated in FIG. 6. The hook of the hanging profile 3 engages around the free end of the hook receptacle 43 and the first, shorter leg of the hanging profile 43 lies against that surface of the thinner extension of the fastening leg 42 which faces away from the rolling blind housing 1. The free end of the shorter leg of the hanging profile 3 butts here against a shoulder between hook receptacle 43 and thicker part of the fastening leg 42. Said shoulder forms a second stop surface 432. A lug 430 facing the roller blind housing 1 is arranged at the free end of the hook receptacle. The lug 430 preferably forms a right angle with the rest of the hook receptacle 43. The lug 430 preferably extends into the plane which is defined by the first stop surface 420. The lug 430 together with the two stop surfaces 420, 432 mentioned prevents wobbling of the hung hanging profile 3. In addition, the hanging profile 3 can be fixed in said hung position by one or more screws 30.

[0049] The mounting profile 4 according to the invention permits hanging of the roller blind web 2 perpendicularly to the door surface. On the one hand, this facilitates the hanging. However, the substantial advantage is that the mounting profile 4 requires relatively little space and can therefore also be arranged next to an existing handlebar H of a door. This can readily be seen in FIGS. 3 and 5.

[0050] If the space between door leaf edge and handlebar H is even more limited, the handlebar H extends over the entire width of the door leaf as far as the door leaf edge or if such an arrangement is desired for other reasons, a solution according to FIGS. 4 and 8 can be selected. The contact leg 40 of the mounting profile 4 is provided with a recess 6 in which the end of the handlebar H engages. The recess 6 can extend as far as the connecting leg 41 or even as far as the fastening leg 42.

[0051] The recess 6 can be provided at the factory. However, it can also be produced at a suitable point in situ by the fitter, for example by milling or by sawing. It can also be pretreated at the factory as a predetermined breaking point.

[0052] In an embodiment not illustrated here, the mounting profile 4 is also divided into two pieces arranged above and below the handlebar H. The fastening strip 20 and the roller blind web 2 are formed in one piece and therefore also extend over that region of the handlebar H which separates the two pieces of the mounting profile 4 from each other.

[0053] The finger guard device according to the invention and the mounting profile according to the invention permit the use of a finger guard device even in the case of door leaves with handlebars.
