Description

TECHNICAL AREA

The present invention relates to a hinge-side finger protection device for a wing door.

STATE OF THE ART

Doors pose an increased risk of accidents, especially for small children. It happens again and again that fingers get caught in the gap between the door leaf and the door frame. The forces acting on the trapped fingers are great, as is the resulting injury.

Devices are therefore known from the prior art which are intended to provide protection against unintentional trapping of the fingers. There are finger protection devices for the hinge-side as well as for the counter-hinge-side secondary closing edges of the wing door.

The hinge side is that side of the door leaf on which the door hinge, i.e. the door hinge is arranged. The opposite hinge side is on the opposite side of the door leaf. The lock side of the door leaf is at the other end of the door, namely by the door lock and the door handle.

In DE 37 16 654 the use of a roller blind is suggested to cover the gap on the opposite hinge side. The hinge side is protected by cover strips which are glued to the door frame between the door hinges.

It is also known from the prior art to screw on such cover strips or to manufacture them as protective profiles made of metal and to clip them onto plastic holders. If it is necessary to remove a door leaf, e.g. When moving or renovating, these finger guards can only be removed with great difficulty.

DISCLOSURE OF THE INVENTION

It is therefore an object of the invention to provide an improved hinge-side finger protection device.

This object is achieved by a finger protection device on the hinge side with the features of claim 1.

The hinge-side finger protection device according to the invention for a wing door has at least one protective profile and at least one fastening means for fastening the protective profile to a door frame of the wing door. The protective profile can be slipped onto the fastening means, the protective profile receiving the fastening means in the plugged-on state, whereby it preferably completely accommodates it or completely covers it. According to the invention, the protective profile can be removed from the fastening means in a non-destructive manner and can be pushed onto it again.

Since the protective profile can be detached from the fastening means easily and non-destructively, the use of the finger protection device is simplified. It can be removed at any time, which enables fast and therefore inexpensive processing, especially when installing the doors or renovating. The loosening is preferably done by hand and in particular without the use of special tools.

It is also advantageous that the protective profile can have a relatively simple shape so that it is inexpensive to manufacture. It can also be designed according to the architect's design requirements and thus designed to be visually appealing. The appearance of the door is not affected by this finger protection device.

In a preferred embodiment, the at least one fastening means is a clip, in particular a resilient clip. In alternative embodiments, the protective profile has an interior space for receiving the at least one fastening means and, in this interior space, a clip for connecting to the at least one fastening means.

The clip itself is preferably screwed to the door.

The clip is preferably designed to be axially symmetrical in cross section. This facilitates manufacture and assembly.

In a preferred embodiment, the clip has a flat bottom which merges into a first leg on two opposite sides, each first leg merging into an inwardly extending receiving bay and each receiving bay merging into a free-ending second leg. Thanks to the flat bottom, the clip can be easily attached to the door frame. Thanks to the first and second legs, the receiving bays can be pressed inwards when the protective profile is attached, whereby, thanks to the shape of the clamp, they exert counter-pressure on the protective profile and thus hold the protective profile in its position. By tilting the protective profile slightly to the side, it can be released from the clamp. The first and second legs are preferably inclined, i. E. at an angle other than 90 ° to the ground.

The resilient effect and the simplification of the detachment of the protective profile are increased when the first two legs open obliquely outwards from the floor. The same applies if the two second legs are inclined inwards towards a longitudinal center axis.

The two receiving bays are preferably arranged at the same height in relation to the floor. This also facilitates the assembly and removal of the protective profile.

The clip is preferably made thin. Preferably it is made of a metal preferably made of spring steel.

The protective profile is preferably formed axially symmetrical in cross section. This reduces manufacturing costs and simplifies assembly.

The protective profile preferably has two inwardly protruding ribs for engaging in the receiving bays. This is a simple and inexpensive design. If the ribs are designed to be rectilinear in extent and / or if they extend at an angle of 90 ° to the side walls of the protective profile, insertion into the receiving bays is made easier. The ribs preferably extend over the entire length of the protective profile. However, they can also only be present in sections, namely where the clamp is likely to come to rest in the assembled state. The ribs are preferably formed in one piece with the rest of the protective profile. However, they can also be designed as elements that can be fastened to the protective profile.

The protective profile is preferably made of metal or plastic. It is preferably made approximately stiff or stiff.

In a preferred embodiment, the protective profile has two opposing, freely ending legs. These legs preferably protrude beyond the ribs and thus cover the lower area of the clamp near the door frame.

The legs preferably have free ends which each have a bevel, a taper or a step that is inclined or thinned towards the bottom. This makes it easier to remove the protective profile with the aid of a tool, e.g. a screwdriver.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

Figure 1 shows part of a wing door with door wing F, door frame R and a band B, also called a door hinge or door hinge. A wall adjacent to the door frame R is provided with the reference symbol W.

The band B has a band upper part, a band lower part and one in which Figure 1 Pivot pin shown in dashed lines. The upper part of the hinge is attached to the door leaf, also known as the door leaf. The lower part of the hinge is attached to the door frame, also called the frame or frame. A door usually has two such bands B, which are arranged distributed over the height of the door.

The finger protection device is arranged below the lower band B shown here, between the two bands and above the upper band. It has a corresponding number of protective profiles 1 and clips 3 for fastening the protective profiles 1.

The protective profiles 1 are preferably shaped in such a way that they form a curved surface that is aligned with the band B. I.e. their surfaces are preferably flush with the belt surface in all vertical planes.

Fewer finger guards can also be used. I.e. for example, only the area below the lower band B and / or the area between the two bands can be protected. If the finger protection device is used in several areas, its parts are preferably designed to be identical except for the length and the number of clips to be used.

The finger protection device prevents access to the gap that arises between the door leaf F and the door frame R when the door leaf F is opened. This is especially true for rebated doors, like one of them in Figure 1 is shown by way of example.

In the Figures 2 to 6 the finger protection device according to the invention is shown in detail. The protective profile 1 is preferably made of a metal or a plastic. It is preferably made stiff or approximately stiff. Almost stiff means that it can only bend slightly when it is placed on the clamp or when it is released from the clamp, but the clamp causes the force to act.

The protective profile 1 has an essentially U-shaped cross section with a curved back. It is preferably designed to be axially symmetrical with respect to its longitudinal center axis L. It has a base body 10, two inwardly directed ribs 12 and one leg 11 each adjoining the ribs 12. The legs 11 end freely, the free ends being provided with a bevel 13. The chamfers 13 are inclined inwards, as shown in FIG Figures 4 to 6 is easily recognizable. In the representation according to Figures 2 and 3 a step is shown instead of the bevel 13, the longer area of the legs 11 also running on the inside.

The ribs 12 preferably extend over the entire length of the protective profile 1. As a result, the protective profile 1 can be manufactured by the meter and shortened to the desired length for use.

The ribs 12 are preferably made thicker and thus more stable than the wall of the rest of the protective profile 1. The base body 10 preferably has a constant wall thickness. The legs 11 are preferably of the same thickness as the wall of the base body 10.

The clip 3 is preferably made of metal, in particular of spring steel. It is designed to be resilient.

The bracket 30 has a flat bottom 30 with which the bracket 3 rests on the surface of the door frame R in the assembled state. This base 30 preferably has one or more through openings which cannot be seen in the figures. This through opening is used to attach the bracket 3 to Frame R. The fastening element used for this purpose in this example is a screw 2. Alternatively or in addition, nails or other fastening elements can also be used.

The base 30 merges in one piece into first inclined legs 31 on two opposite sides. These end in inwardly directed and outwardly open receiving bays 32, which in turn merge in one piece into second inclined legs 33.

The first legs 31 are inclined outwards, the second legs 33 are inclined inwards. The angles of the inclinations of the first and second legs 31, 33 are preferably different. The angle of inclination of the second legs 33 is preferably greater than that of the first legs 31.

The receiving bays 32 serve to receive the ribs 12, as shown in FIG Figure 6 is easily recognizable. In the lower area, the receiving bays 32 have an approximately horizontally extending base area on which the rib 12 comes to rest. The upper region of the receiving bays 32 is preferably inclined obliquely upwards in order to facilitate the introduction into the bays 32 and also the removal of the ribs 12 from the bays 32.

When the protective profile 1 is slipped on, the bays 32 are pressed slightly inward and the clamps are slightly pressed together. Thanks to the resilient restoring force, the protective profile 1 is releasably held on the clamp 3.

By tilting the protective profile 1 slightly in one direction, one of the ribs 12 can be released from the receiving bay 32 of the clamp 3 and the protective profile 1 can easily be removed again.

In the Figures 7a to 9b the individual steps for assembling the finger protection device are shown. The Figures 7a and 7b show the situation before the finger protection device is installed. In the Figures 8a and 8b the brackets 3 are mounted. In the Figures 9a and 9b the protective profiles 1 are attached.

The finger protection device according to the invention on the hinge side can be easily installed and removed again.
