Description

TITLE Finger guard for a hinged door

TECHNICAL FIELD The present invention relates to a finger guard for a swing door.

STATE OF THE ART

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

Therefore devices are known from the prior art, which should provide protection against accidental pinching of the fingers. In a variant solution, the gap between the gegenbandseitigen Nebenschliesskante the door leaf and the door frame is covered with a textile protective blind, which is attached on the one hand to the door frame and on the other hand on the door leaf. Such a protective roller blind is disclosed for example in GB 2 164 690. The roller blind housing, which includes a shaft for winding the textile runway, is provided with a sliding block. On the door frame, a V-shaped holder is mounted, in which the sliding block can be inserted to hold the housing. The free edge of the roller blind is provided with a stiff end bar, which is screwed to the door. Thus, only the housing, but not the end bar can be easily solved.

Also DE 37 16 654 discloses a roller blind as finger protection, wherein the blind housing is bolted to the door frame. The free edge of the blind is held in a groove of a strip, which is bolted to the door leaf. This device has the disadvantage that the fastening screws are visible and freely accessible. They disturb the appearance of the door. In addition, the screws can be easily solved, which favors unauthorized manipulation. The latter can be fatal, especially in public buildings, such as in schools or day-care centers.

In DE 20 2008 016 094 U a manipulation by loosening the screw is to be prevented and the assembly can be simplified. Here are therefore both door frame side as well as door leaf side holder available, which are screwed onto the door frame or on the door. The housing of the roller blind and the free edge of the roller blind are arranged in fastening means which can be snapped into these holders and cover the fastening screws.

This device has the disadvantage that a solution of the connection is possible only with a special tool. There is also the risk that the holder or the fastener is destroyed when loosening. Furthermore, a readjustment of the holder is no longer possible, since the fastening means cover the screws with which the holders are screwed to the door leaf and the frame.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a finger protection device which allows quick installation and despite concealed fasteners easy adjustment and readjustment of the blinds.

This object is achieved by a finger protection device having the features of claim 1.

The inventive finger protection device for a hinged door has a roller blind, which has a housing, a first fastening means and a web. The roller blind can be fastened by means of the housing and the first fastening means to a door frame and to a door wing of the hinged door, so that the web, when the device is used as intended, forms a gap between the door leaf and the door frame covered. The web has at its free edge an end bar which is held in a second fastener, the second fastener being connectable to the first fastener to tension the web between the housing and the first fastener. The second attachment means is a suspension unit which can be suspended in the first attachment means to tension the web, whereby the attachment of the second attachment means to the first attachment means is tool-free and non-destructive again solvable.

The fact that the web can be hooked together with the second fastener, the device is simple and quick to install. It is just as easy to disassemble again, for example when the door has to be unhooked.

In contrast to devices in which the fastener must be plugged or snapped in place, the suspension is non-destructive and without tools again solvable. The suspension connection according to the invention can also be loosened and reassembled as often as desired during installation and in a very simple manner.

Furthermore, the screws are immediately accessible. As a result, a readjustment of the device is simplified. Furthermore, even after repeated loosening no material fatigue is present, so that damage to the fasteners is not to be feared.

The first fastening means preferably has a hook receptacle and the second fastening means has a suspension hook or vice versa. This facilitates that Hook. Alternative arrangements are possible.

The first fastening means preferably has a fastening surface for fastening the first fastening means to the door frame or to the door leaf, wherein the second fastening means can be suspended approximately in the direction parallel to this fastening surface.

The hooking in this direction favors a readjustment of the second fastening means in its vertical position relative to the first fastening means. That The end bar of the roller blind can be moved in height and thus the track in angled vertical plane. This angular orientation prevents the web from wrinkling when opening and closing the door, especially when made of a textile material. It is also advantageous that the adjustment can be made in the horizontal direction separately from the adjustment in the vertical direction.

Furthermore, the hooking in this direction allows the formation of optimally narrow first and second attachment means.

In preferred embodiments, the second attachment means is a hooked hanger bar which extends in length approximately the entire width of the lane. The width of the web is measured in this text in the vertical direction and thus in the direction transverse to the extension direction of the roller blind, ie along the height of the door frame and the door leaf. Also, the first fastening means is preferably a fastening strip, which extends in its length approximately over the entire width of the web. Preferably, the web extends over approximately the entire height of the door leaf. In one embodiment, the first and / or the second fastening means extend only in sections over the entire width of the web. However, in preferred embodiments, the second attachment means is hinged over approximately its entire length in the first attachment means and preferably extends approximately over entire width or height of the web.

Preferably, the second attachment means is longitudinal, i. in its vertical mounting position, adjustable relative to the first fastening means. Preferably, it is fixable in its vertical position relative to the first fastening means.

Preferably, the first fastening means with at least one first fastening element on the door leaf or on the door frame can be fastened, the web covers the at least one first fastening element when used as intended in the tensioned state. Preferably, the suspension unit is in the mounted state laterally spaced from the first attachment means. Thus, the web protects the at least one fastener from manipulation. On the other hand, it is easily accessible once the train is posted. Preferably, the first fastening element has at least one elongated hole extending transversely to the longitudinal direction of the fastening element, wherein the first fastening element is at least one screw which can be passed through the slot for fastening the first fastening means to the door leaf or to the door frame. As a result, the first fastening element can be displaced in the direction transverse to the door frame or door leaf. This slot is preferably covered by the tensioned track, but exposed when the track is unhooked. A simple installation and easy readjustment of the device are thus possible.

In preferred embodiments, the first attachment means is formed substantially plate-shaped and it has a rear handle for receiving the suspension unit.

In a preferred embodiment, the housing has a base body for receiving the web and a side projection projecting the main body, wherein the projection for fixing the housing on the door or the door frame is used and wherein the web covers the projection when used as intended in the tensioned state. This projection preferably also has holes, in particular elongated holes, in order to mount the housing by means of screws. He, too as well as the screws are exposed when the track is not hooked, and they are otherwise covered by the track. Again, this facilitates the assembly and the readjustment. Preferably, the second fastening means is changeable in its position relative to the first fastening means, preferably also in the suspended state. Preferably, the second attachment means can be mounted at any height in the first attachment means. Preferably, it can even be moved in the suspended state in the vertical direction. This also facilitates the readjustment.

In preferred embodiments, at least one second fastening element is present, by means of which the second fastening means can be fixed in its position relative to the first fastening means. This at least one second fastening element is preferably a grub screw, which is inserted from the outside through the second fastening element and abuts the first fastening element, so that further displacement in the vertical direction is impossible and the second fastening element is blocked in its position in the vertical direction. Usually, this at least one second fastening means also prevents the fastening strip from being hung out.

Preferably, the second attachment means has a substantially U-shaped cross section with a first leg, a second leg and a web connecting the two legs, wherein the first leg is for hanging and the second leg is extended relative to the first leg and an outwardly directed groove, in which the end bar is inserted. This is an easily manufactured form, which also has the advantage that it is relatively small and narrow and thus does not disturb the appearance of the door.

Preferably, the first fastening means has a base body in the form of a plane-parallel stop plate having a first and a second surface, wherein on the first surface an inner side of the second fastening means in the suspended state, wherein the stop plate merges on a longitudinal side in a suspension plate, which is thinner is as the stop plate and forms a rear handle, and wherein the stop plate on its opposite longitudinal side merges into a mounting plate for attachment of the first attachment means on the door leaf or on the door frame. Again, this is a relatively inexpensive and narrow design. The stability of the Einhängeverbindung is also increased when the Einhängeplatte has on its free longitudinal side a protruding nose, which is present in the suspended state of the second fastening means on an inner wall of the second fastening means. This prevents tilting or wobbling of the fastening means relative to each other. If the stop plate is located on an inner side of the second leg, tilting or wobbling of the fastening means is additionally or alternatively avoided.

Preferably, the housing is on the door leaf and the first attachment means is attached to the door frame. This increases the free passage through the door frame when the door is hung.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figures 1 to 7, a preferred embodiment is shown. Figure 1 shows a door with a door frame R and a door leaf F. The door hinge B is not visible in this figure, but it is covered by the inventive finger protection device S. As can be seen 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 arises between the door frame R and the door leaf F when the door is open.

FIGS. 2 and 3 show a cross section through a part of FIG. 1, so that the finger protection device S according to the invention is better recognizable.

It essentially consists of a roller blind. In a roller blind housing 2, a shaft 10 is arranged. On the shaft 10, a blind sheet 1 is wound. The web 1 is preferably made of a textile material. The shaft 10 is spring-loaded, so that an automatic retraction of a developed part of the web 1 takes place. This arrangement is well known in the art.

The free edge of the web 1 is reinforced with an end bar 11. This can be done by thickening the web 1 itself. Usually, however, the edge with a metal or Plastic strip connected. This end bar 11 is in a suspension strip 3, which is formed hackenförmig.

At the counterpart of the door, here on the door frame R, a fastening strip 4 is screwed as the first fastening means. The suspension bar 3 forms a second fastening means, which can be suspended in the first fastening means. This is clearly visible in FIGS. 2 and 3. Thanks to the restoring force of the roller blind, the web 1 is tensioned in the suspended state in any position of the door leaf F. In each case, it covers the gap between the door frame R and the door leaf F. The web 1 thus protects against accidents on the side opposite the band B.

FIGS. 4 and 5 clearly show how the finger protection device S according to the invention is mounted. First, the housing 2 is fastened with at least one first screw 22 on the door leaf F and then the fastening strip 4 is mounted.

The housing 2 has a base body 20, in which the shaft 10 and the wound web 1 are held. The base plate of the base body 20, with which the housing 2 bears against the door leaf F, extends into 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 extending away from the base body 20. This projection 21 can be fastened to the door leaf with the at least one first screw 22. Preferably, a plurality of first screws 22 are present. As a result, the housing 2 is fixed to the door leaf F. Other fixings, e.g. on the projection 21 opposite side of the body 20, are not necessary. Depending on the shape and size of the housing 2, however, further fasteners may be present.

On the opposite side of the finger protection device S, that is on the door frame R, the first fastening means, here the fastening strip 4, attached. This fastening strip 4 preferably also extends approximately over the Overall length of the door frame R. It is particularly preferably formed the same length as the housing. 2

The web 1 is held fixed to the end bar 11 in the suspension bar 3. For this purpose, the suspension bar 3 has a main body 30, which has a substantially U-shaped cross-section. A first leg 32 of the U-shaped main body 30 forms a suspension hook. A second, longer trained leg has a groove 31 at its free end. This is designed as a holder. The opening of the groove 31 is located on the side opposite the hook hooked 32 side of the second leg and is directed to the outside. The hanger 31 preferably extends over the entire length of the suspension bar 3. The suspension bar 3 is preferably the same length as the mounting bar 4 and how the housing 2. At least the suspension bar 3 and the groove 31 are the same length as the web 1. The end bar 11th is inserted in the groove 31. It is pivotally held in it.

The fastening strip 4 has a stop plate 40. On one longitudinal side of the stop plate 40, it merges in one piece into a suspension plate 42. The suspension plate 42 is thinner than the stop plate 40. The suspension plate 42 has a projection 4 directed vertically away from the door frame R or a nose 420. On the opposite side of the Einhängeplatte 42, the stop plate 40 is integrally into a mounting plate 43 via. The mounting plate 43 is preferably thinner than the stop plate 40. It preferably has at least one slot 46, preferably a plurality of slots 46, on. The elongated holes 46 extend in the direction transverse to the longitudinal direction of the fastening strip 4, that is to say in the horizontal direction when the finger protection device S is mounted.

The fastening strip 4 is screwed by means of at least one third screw 5 on the door frame R. The slots 46 allow a horizontal displacement of the mounting bar 4 without new holes must be drilled.

The stop plate 40 is located with its back flat on the door frame R on. An assembly adhesive tape 45, which is preferably arranged behind the mounting plate 43 is, facilitates the assembly. The mounting tape 45 may, but need not extend over the entire length of the mounting strip 4. The suspension plate 42 forms in the assembled state of the fastening strip 4 a rear grip. In this rear grip of the hooks 32 of the suspension bar 3 engages, the suspension bar 3 can be suspended at different heights and thus the angle of the blind sheet 1 is easily varied. This is clearly visible in FIGS. 6 and 7. In the suspended state, the front planar surface of the stop plate 40 abuts against the inside of the second leg of the suspension strip 3. The nose 420 is also on this inside, so that a wobble is prevented.

The suspended suspension bar 3 can be fixed by means of one or more second screws 33 in its vertical position. The at least one second screw 33 is preferably a grub screw, which is pressed through the second leg of the fastening strip 3 on the suspension plate 42.

The web 1 can be easily unhooked by this second screw 33 is easily solved.

As can be clearly seen in Figure 3, covered the track 1 in the suspended state, the projection 21 with the first screw 22 as well as the mounting plate 43 with the third screw 5. Since the web 1 can not hang so easily without loosening the second screw 33 , the fastening screws 22 and 5 are well protected against manipulation. However, if the track 1 is unhooked, these screws 22, 5 are easily accessible and a readjustment of the finger protection device in the already mounted state can take place in a simple manner.

It is particularly advantageous that the adjustment takes place in the horizontal X-direction and vertical Y-direction by separate means. As already mentioned above, the fastening strip 3 can be moved in the horizontal direction thanks to the elongated holes 46. Thanks to the sliding in the vertical Y direction hook 3 can be optimally adjusted to this orientation of the web 1. It is also advantageous that these vertical Adjustment can even be done while the door is opened and closed several times to find the optimum position. For fixing, as mentioned on both sides, only the at least one second screw 33 must be screwed.

The inventive finger protection device is thus robust, consists of the simplest means and still allows optimal protection against manipulation and a maximum amount of Nachjustierbarkeit. Furthermore, it has an appealing design.
