Description

TECHNICAL AREA

The present invention relates to a 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 trapped between the pivoting door leaf and the door frame. The forces acting on the trapped fingers are great, so the resulting injury can be serious.

Devices are therefore known from the prior art which are intended to provide protection against unintentional trapping of the fingers. In one variant of the solution, the gap between the secondary closing edge of the hinged door leaf on the opposite hinge side and the door frame is covered with a textile protective roller blind, which is attached to the door frame on the one hand and to the hinged door leaf on the other.

Such finger protection devices with roller blinds show, for example GB 2 164 690 , DE 20 2008 016 094 U such as DE 37 16 654 . It has already been recognized in the prior art that it is desirable that the finger protection roller blind can be released quickly at least on one side. This can be helpful, for example, if a door has to be removed. The loosening and hanging of the roller blind, however, takes time and especially the hanging is time-consuming for people who have little practice in this regard. It is sometimes difficult for them to reattach the roller blind without drapery.

U.S. 3,137,042 A discloses a swing door with upper and lower hinges. A stiff profile rail surrounds the face of the shorter leg of the swing door leaf. This profile rail has openings through which guide rollers pass. The guide rollers are attached to the door frame.

DISCLOSURE OF THE INVENTION

It is therefore an object of the invention to create a finger protection device that is as practicable as possible.

This object is achieved by a finger protection device and a finger protection roller blind with the features of claim 1.

The finger protection device according to the invention for a wing door has a protective cover for covering a gap between a door frame and a pivotable door wing. The protective cover has a rear side which, when the finger protection device is used as intended, faces the door leaf and the door frame. According to the invention, the finger protection device has a window which allows access to the rear of the protective cover.

The window forms an opening or a recess in the protective cover.

The window is designed to be lockable, so that it normally does not offer any access, but has to be opened first.

The window is preferably provided with a child safety device so that small children in particular cannot open the window. This child safety device is, for example, a corresponding snap or latching mechanism, as is known, for example, for can lids or bottle closures. In other embodiments it is formed by one or more screws.

Thanks to the finger protection device according to the invention, access to a specific area behind the protective cover can be created in a simple manner without the remaining protective cover having to be detached.

This is particularly advantageous in the case of pivotable door leaves which form part of a sliding door or sliding gate arrangement. Should, for example, the pivoting door leaf be fixed inside the sliding gate, for example by lowering a locking bolt by hand, the window in the protective cover can be opened, the bolt lowered and the window closed again.

Simple wing doors, which are held pivotably in a stationary door frame, can also be provided with such a finger protection device with a window. The reason for this is, for example, that simple and quick access to a people counter, to a sensor of a security or access system or to another type of sensor should be made possible.

The finger protection device according to the invention is thus not limited to sliding door or sliding gate arrangements, but it can also be used in other constructions which have pivotable wing doors.

Depending on the position and size of the window, it can allow access to the door frame or the door leaf or to both at the same time.

In this text and in the claims, the term "door frame" denotes stationary door frames and stationary walls, which are designed as door frames, and also sliding doors, sliding gates, folding walls and sliding walls in which pivoting door leaves are embedded. It also includes other similar components.

The protective cover has a partial area which forms a window sash, thanks to which the window can be opened and closed again. The window sash is movably arranged. Depending on the embodiment, it is, for example, displaceable or pivotable. The window arrangement in the finger protection device can be designed simply and inexpensively and just as easily opened and closed if the window can be opened by means of a flap and can be closed by means of this.

The finger protection device preferably has a front side which is opposite the rear side, the window sash being able to be opened from this front side. In the closed state of the window, the window sash preferably forms part of this front side. The surface of the window sash is preferably aligned with this front side or at least does not protrude significantly from it. The window sash is preferably part of the protective cover, and in preferred embodiments it is formed from the same material as the rest of the protective cover.

The protective cover is preferably a flat web with a first web end for attachment to the door frame and with a second web end for attachment to the door leaf.

The window can be located in the protective cover at any point selected by the manufacturer and adapted to the intended use. In preferred embodiments, however, the window extends to the first or second track end, the window sash having a free sash end which can be fastened to the door frame or the door sash and is designed accordingly, the free sash end being independent of the associated first or second track end of the track on Can be fastened to the door frame or to the door leaf.

The finger protection device preferably has a first fastening strip to be attached on the door frame side or on the door leaf side, and the free wing end is preferably provided with a second fastening strip which can be releasably connected to the first fastening strip in a form-fitting and / or force-fitting manner. In this way, the window sash can be loosened and reattached independently of the protective cover and nevertheless, when the window is closed, it forms a unit with the rest of the protective cover and thus does not impair the visual appearance of the entire finger protection device.

The first fastening strip is preferably part of a first fastening means which is designed to fasten the web over its entire length, which is vertical when used as intended, on the door leaf or door frame. This also enables a uniform image of the finger protection device despite the window.

The protective cover can be shaped as desired. In particular, the flat webs known in the prior art can be used, such as roller blinds, textile covers or covers made of rigid or semi-rigid plastic materials, which are planar, curved, scale-shaped or designed as bellows.

In preferred embodiments, the finger protection device has a self-winding roller blind, the roller blind comprising a housing for fastening the roller blind to the door frame or door leaf and the flat sheet which can be wound up in the housing, and the finger protection device comprising a first fastening means for fastening the roller blind to the door leaf or on the door frame to tension the web between the housing and the first fastener. Such roller blinds have proven themselves in the prior art. They are easy to assemble and disassemble.

The web, in particular the roller blind web, preferably has an end strip at its free web end, which is held in a second fastening means, wherein the second fastening means can be connected to the first fastening means in a form-fitting and / or force-fitting manner in order to create the path between the housing and the first tightening fasteners. This facilitates the assembly and disassembly of the entire device.

In preferred embodiments, the first fastening strip has the same cross section as the first fastening means and the second fastening strip has the same cross section as the remaining part of the second fastening means. This optimizes the appearance.

In a preferred embodiment, the second fastening means is a suspension unit which can be suspended in the first fastening means in order to tension the web. The second fastening means is preferably a hook-shaped curved hanging strip which extends in its length over approximately the entire width of the web.

In another preferred embodiment, the second fastening means is a clip which can be snapped into the first fastening means in order to tension the web.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

• Figure 1 shows a sliding gate or a sliding door T which closes an opening in a wall W. A pivotable door leaf F is arranged in the sliding door T, so that the frame of the associated opening forms a door frame R. The secondary closing edge of the door leaf F, preferably the opposite hinge side, is covered by a finger protection device S in order to avoid trapping hands or fingers. The finger protection device S has a window 6 which enables access to an area behind the finger protection device S.
• Figure 2 Figure 3 shows a similar device, the frame R being embedded in a stationary wall. In this figure it can be better seen that the finger protection device S has a protective cover, here in the form of a sheet 1, which is attached to the door frame R and to the door leaf F and thus covers the gap of the secondary closing edge between the door frame R and the door leaf F.

The finger protection device S preferably extends approximately over the entire height of the door leaf F.

Various types of finger guards with protective covers can be used. However, the device preferably has a roller blind. A device that has already proven itself on the market is in the Figures 3 to 6 shown.

This finger protection device essentially consists of a roller blind. A shaft 10 is arranged in a roller blind housing 2. The roller blind 1 is on the shaft 10 wound up. The web 1 is preferably made of a textile material. The shaft 10 is spring-loaded so that an automatic retraction of an unwound part of the web 1 takes place.

The free end of the web 1 is reinforced with an end strip 11. This can be done by thickening the web 1 itself or by means of a sewn-in or otherwise introduced piping. In preferred embodiments, the free end is additionally or alternatively connected to a metal or plastic strip. This end strip 11 is held in a hanging strip 3 which is designed in the shape of a hook.

The housing 2 of the roller blind is preferably attached to the door frame R. In the ones shown here Figures 3 to 6 however, it is attached to the door leaf. A fastening strip 4 is screwed onto the counterpart of the door, here on the door frame R, as the first fastening means. The hanging bar 3 forms a second fastening means which can be hung in the first fastening means. This is in the Figures 3 and 4 good to see. Thanks to the restoring force of the roller blind, the web 1 is tensioned in any position of the door leaf F in the suspended state. It covers the gap between the door frame R and door leaf F. The sheet 1 thus protects against accidents on the side opposite the strip B, for example it prevents hands or fingers from getting caught in the gap.

In the Figures 5 and 6 Individual elements of the finger protection device S are shown in an exploded view, so that the type of assembly can also be clearly seen.

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 rests on the door leaf F, preferably 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. This projection 21 can be fastened to the door leaf with at least one first screw 22. A plurality of first screws 22 are preferably provided. As a result, the housing 2 is fixed on the door leaf F. Further fastenings, for example on the side of the base body 20 opposite the projection 21, are not necessary. Depending on the shape and size of the housing 2 can however, other fixings may still be present.

On the opposite side of the finger protection device S, that is to say on the door frame R, the first fastening means, here the fastening strip 4, is fastened. This fastening strip 4 preferably also extends approximately over the entire length of the door frame R. In particular, it is preferably of the same length as the housing 2.

The web 1 is held in the hanging bar 3 by the trailing edge 11. For this purpose, the hanging bar 3 has a base body 30 which has an essentially U-shaped cross section. A first leg 32 of the U-shaped base body 30 forms a suspension hook. A second, longer 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 of the second leg opposite the hook 32 and is directed outwards. The groove 31 preferably extends over the entire length of the hanging bar 3. The hanging bar 3 is preferably of the same length as the fastening bar 4 and like the housing 2. At least the hanging bar 3 and the groove 31 are made the same length as the track 1.

The end strip 11 is inserted into the groove 31. It is held in it so that it can pivot.

The fastening strip 4 has a stop plate 40. On one long side of the stop plate 40, it merges in one piece with a mounting plate 42. The suspension plate 42 is made thinner than the stop plate 40. The suspension plate 42 has a projection or a nose directed perpendicularly away from the door frame R. On the opposite side of the suspension plate 42, the stop plate 40 merges in one piece with a fastening plate 43. The fastening plate 43 is preferably made thinner than the stop plate 40. It preferably has at least one elongated hole 46, preferably a plurality of elongated holes 46. The elongated holes 46 extend in the direction transverse to the longitudinal direction of the fastening strip 4, that is, in the horizontal direction when the finger protection device S is installed.

The fastening strip 4 is on the door frame R by means of at least one third screw 5 screwed tight. The elongated holes 46 allow the fastening strip 4 to be displaced horizontally without new holes having to be drilled.

The back of the stop plate 40 rests flat against the door frame R. An assembly adhesive tape 45, which is preferably arranged behind the fastening plate 43, facilitates assembly. The assembly adhesive tape 45 can, but does not have to, extend over the entire length of the fastening strip 4. In the assembled state of the fastening strip 4, the suspension plate 42 forms a rear grip. The hanging hook 32 of the hanging bar 3 engages in this rear grip, the hanging bar 3 being able to be hooked in at different heights and the angle of the roller blind 1 being thus easily variable. This makes it possible to prevent the roller blind 1 from wrinkling during use.

In the suspended state, the front, flat surface of the stop plate 40 rests against the inside of the second leg of the suspension bar 3. The nose is also on this inside, so that wobbling is prevented.

The suspended hanging bar 3 can already hold in a form-fitting manner in the vertical direction. However, it is preferably not yet fixed in the vertical. However, it can preferably 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 grub screw which is pressed through the second leg of the fastening strip 3 onto the mounting plate 42. This is for example in the Figures 5 and 8th good to see.

The track 1 can easily be unhooked by slightly loosening this second screw 33.

As in Figure 4 As can be seen clearly, the track 1 covers the protrusion 21 with the first screw 22 and the fastening plate 43 with the third screw 5 when it is hung 22 and 5 well protected from manipulation.

If the web 1 is unhooked, however, these screws 22, 5 are easily accessible and readjustment of the finger protection device in the already assembled state can be carried out in a simple manner.

According to the invention, at least one window 6 is present in the protective cover, here in the roller blind 1. In the Figures 7 and 8th this window 6 is arranged in the lower area of the finger protection device S. As in Figure 10 can be seen, there is in the open state an activation element 7, here a slide of a flush bolt, free. The window 6 can also be provided at a different height depending on the area of application. For example, it can enable access to a sensor arranged in the door leaf F or in the door frame R.

As in the Figures 7 and 8th As can be clearly seen, the roller blind 1 has a cutout 12 in which the window 6 is located. In this example it extends to the free end of the roller blind 1. Depending on the embodiment, however, it ends at a distance from this end. It is preferably aligned with the rest of the roller blind 1 or only protrudes slightly from it. It is preferably made of the same material as the rest of the roller blind 1.

In the Figures 9 and 10 it can be seen that the window has a window sash 60, here in the form of a flap. This can be opened from the front of the roller blind 1, ie from the outwardly directed side.

The window sash 60 is formed by a cut-out flap part 62 of the roller blind 1 itself and an overlap part 63 connected to it. The overlap part 63 preferably consists of a piece of fabric which has a larger base area than the flap part 62 and which is glued to this and to the roller blind 1 in such a way that the overlap part 63 rests on the surrounding material of the roller blind 1 when the window is closed.

Since the window 6 extends to the free end of the roller blind 1, the hanging bar 3 is interrupted in this area. However, the fastening strip 4 preferably also extends over this area. In another embodiment is however, instead of the fastening strip 4, a differently shaped first fastening strip is present.

The window sash 60 preferably has a free sash end which is provided with a second fastening strip which can be connected to the first fastening strip in a form-fitting and / or force-fitting manner so that the window is held fixed in the closed position. So that this connection is not opened unintentionally, it can be provided with a child protection device.

In this example, the second fastening strip is shaped the same as the hanging strip 3 of the rest of the roller blind 1 and thus forms a hanging strip 61. It preferably extends over approximately the entire vertical height of the flap part 62, so that it closes the gap in the hanging strip when it is hung 3 almost closes. The overlapping part 63 is preferably additionally provided with a reinforcement, for example likewise in the form of a strip or a welt extending over its entire vertical height. In the closed state, this bar rests preferably on the fastening bar 4 or is located at a distance from it.

In Figure 11 it can be clearly seen how the window sash 60 can be unhooked when the roller blind 1 is hung by loosening the hanging strip 61 in order to open the window. In the suspended state, the suspension strip 61 can also be fixed on the fastening strip 4 by means of one or more screws, preferably grub screws. In this example, these screws form the child safety device 64 mentioned above. This is in the form of a single screw in Figure 9 recognizable.

Other types of fastening of the roller blind are possible. For example, the free end of the roller blind 1 and / or the free end of the window sash 60 can be held positively and non-positively in the first fastening means by means of a clip connection. Additional locking screws such as the grub screws mentioned above are unnecessary in this case or can be used in addition.

The device according to the invention thus enables easy access to a Part of the secondary closing edge, even if the finger protection device is in the protective position of use. <b> List of reference symbols </b> 1 rail 45 Mounting tape 10 wave 46 Long hole 11th Trailing edge 12th Cutout 5 third screw 2 casing 6th window 20th Base body 60 Casement 21 head Start 61 Hanging strip 22nd first screw 62 Flap part 63 Overlap part 3 Hanging bar 64 Parental controls 30th Base body 31 Groove 7th Activation element 32 Suspension hook 33 second screw B. tape F.
