Finger protection devices for sectoral doors i

ť í

Technology part]

The invention relates to finger protection devices for sectoral doors, each section having one main section and at least one recess bounded to the outer side of the section by an edge section, the adjacent sections being pivotally connected to each other by hinges attached to the main sections formed by the protection profile The finger section, which has a fastening section connectable to the main section of the first section and the guard section, is configured such that in each pivoted position of the first section relative to the second section at least partially overlaps with the edge section of the second section and is retractable into the recess of the second section. The invention further relates to a sectoral door equipped with this device.

BACKGROUND OF THE INVENTION

In the following, the term sector doors refers to all types of doors and gates having at least two hinged sections arranged one above the other or side by side, whereby the separation joints can extend vertically or horizontally. Such sector doors are known in various designs. For example, they are used as garage doors or industrial doors. If no finger protection device is installed, there are gaps in the opening and closing of the door between adjacent sections for a transient period of time in which the finger may be crushed or even detached under inattentive handling. ·

To avoid this danger, sectoral doors can be equipped with finger protection devices.

The finger protection device is known from the German utility model DE 89 10 518 U1. This device utilizes a sealing strip having a sealing lip with a wedge-shaped, linearly limited cross-section. The sealing strip is inserted into the groove along the longitudinal narrow side of the first section, and the sealing lip projects into the flange of the adjacent second section. Both the groove and the grooves are formed as integral parts of the individual sections, so that the finger protection device can only be attached to a sectoral door which has been specially adapted for this purpose.

Patent, trademark and

The Austrian patent AT-390 297 B discloses another finger protection device in which the first section has a curved projection in the form of a circular cylinder which extends into the longitudinal recess in the second section. The curved projection is an integral part of the supporting main section of the first section and, for example, also serves to attach a hinge connecting the door section. . ...... i .....,:;. in

Other finger protection devices are known from Section 6 of the Sectional-Tore article to have a Fingerschutz (Sector Gates with Finger Protection) from Ing. Hugo Wagner, TUR + TORREPORT, 12th year, 1st quarter 1992, pages 10 and 12. The main sections of the individual sections are created with integral protective and marginal sections. The sections are shaped complexly at the longitudinal edges so as to form an interlocking finger guard.

It is an object of the present invention to provide finger protection of the type mentioned at the outset so that it can be manufactured cheaply and simply for a variety of sectoral door designs. In particular, it should be possible to mount finger protection devices on existing doors. Furthermore, the secure attachment of the finger protection device to the door sections should be ensured.

This object is achieved by a finger protection device for sectoral gates, each section having one main section and at least one recess bounded to the outer side of the section by an edge section, the adjacent sections pivotably connected to each other by hinges attached to the main sections formed by the profile. for finger protection, which has an attachment section connectable to the main section of the first section and the guard section, is configured such that it overlaps at least partially with the edge section of the second section in each pivoted position of the first section relative to the second section and is retractable into the The recess of the second section according to the invention, characterized in that the finger protection profile is made of plastic or metal sheet. The protective section of the finger protection profile is curved in cross-section. the finger guard is storable in the recess of the first section and is rigidly connectable to the main section of the first section, but is not integrated into the main section. The contact surface of the finger protection profile is adapted to rest against the edge section of the first section.

The function of finger protection is influenced by the interaction of edge sections with special finger protection profiles, the profiles being not integral parts of the main sections. For this reason, conventional, simply shaped, for example rectangular, main parts can be used to construct the door. Such main sections are much cheaper and can be manufactured in a much larger number of shapes than the known integral finger protection section. It is also possible to produce sections in the widths and thicknesses that are most suitable for the door, in particular from conventional or tapered profiles without taking into account finger protection.

The fact that the finger protection profile must be firmly connected to the main section of the first section and that it can additionally rest against the edge section of the first section, ensures a particularly stable attachment of the finger protection profile to the first section, even if the first section has relatively large tolerances, or when it is curved.

• J · '!

The main section of the section may not be a single piece. It is usually made up of parts that are firmly connected to each other. This is the case, for example, with the door according to the Austrian document AT 390 297 B, according to which the main section of each section consists of two U-sections and at least one intermediate piece.

The profiles of the finger protection device according to the invention are firmly connected to the main sections, i.e. they are screwed, glued, mechanically clamped or riveted, for example. This can be done either in the manufacture of a sectoral door or additionally at the construction site, for example if the client attaches special lining to the sectoral door. Preferably, the attachment means of the finger protection profile do not penetrate through the edge portion so that they are not visible from the outside.

According to the invention, the profiles of the finger protection device can be made of plastic, preferably by extrusion, injection molding or pressing. This embodiment has advantages typical of plastics, for example low weight. If flexible plastic is used, flexible profiles can be formed. Preferably, the plastic profiles are thin and have a material thickness of at most 4 mm. 5 are preferably cavity-free profiles.

The profiles according to the invention can also be made of sheet metal, in particular of aluminum, iron or steel sheet, which can be relatively thin and preferably has a thickness of not more than 1.5 mm or 1 mm. Profiles are made of sheet metal by forming, ie

--- bending -tažením; ^'_ compression or válcóvánímÍ'Rovněž je'možná výroba'z conventional rolled sections. Production is inexpensive and is possible even without expensive special machines and tools in any desired size. One finger protection profile fits many different profiles of conventional steel or aluminum profiles used in the production of sector door sections. The sheet can be lacquered or otherwise surface-adapted.

In addition to finger protection, the profiles also advantageously seal the interspaces between the sections, for example against drafts, rain and dust. This is achieved either by overlapping protective, edge and cover sections forming a labyrinth seal (swirl chamber), or by finger protection profiles attached to the first sections having at least one sealing lip that fits into the region of the first section and / or the area of the adjacent second section.

The profiles according to the invention are not intended to guide individual sections or to articulate them. For this reason, they are not connected to other sections or profiles by any direct form, material or force connections. If the sealing function is not required, the distance between the profiles in the overlapping areas can be quite large, but it is only necessary to prevent a finger from getting between them. The profiles can therefore be manufactured with great tolerances.

. A particularly good protective and sealing effect is obtained if a covering section is attached to the second section, which at least forms an overlapping section of the second section with a protective section and / or an edge section of the first section, the covering section being formed by a plastic or sheet metal cover profile. and each covering profile mounted on the sectoral door is rigidly connected to the main section of the respective second section, but is not an integral part of the second section.

In order to achieve a uniform and relatively narrow distance of the guard and cover sections in each pivoting position, the guard section is preferably shaped such that its curvature, which is curved in section, corresponds to a circular arc whose center lies on the common oscillation axis of the first and second sections sector doors. Furthermore, the cover section of the cover profile, if installed, can also be curved in cross-section. It is particularly advantageous if the curvature of the guard section and / or cover section corresponds to a substantially circular arc whose center of the mounted finger guard device lies on the pivot axis of the first and second sections of the sectoral door relative to each other.

Preferably, adjacent protective, edge and cover sections are shaped such that the overlapping regions are located at a slight distance, and at each pivot position occurring substantially equidistant from each other when using a sectoral door. This prevents the fingers from being pinched whenever the sections are swiveled.

An optically uniform appearance of the sectoral door is achieved if, when looking at the sectoral door from the outside, the adjacent edge sections of both sections are arranged such that when copied to the position (i.e., in one plane) of both sections these adjacent edge sections mostly obscure adjacent sections. Then the profiles do not need to be optically matched to the appearance of the outside of the sections.

In order to achieve a particularly large pivot angle of the sections, the curvature of the protective and / or covering section, which is curved in section, may be substantially semi-circular.

'IN

Preferably, free space is left between the finger protection profile mounted on the first section and the main section or the edge section of the first section. This cavity provides space for heads of fasteners, such as screws or rivets, that retain the lining on the front of the door. For example, if a wooden lining is screwed from the inside of the door, the finger protection profile can easily be retrofitted. Since the finger-protection device is only connected to the relevant main section (and not to other parts such as fittings, hinges, hinges, bearings, running gear, etc.), only the device needs to be removed when detaching the trim for finger protection.

The finger protection device according to the invention, in particular an embodiment which allows a wide range of swinging of the sections, is naturally not only suitable for use in sectoral doors, but also for all types of doors and gates pivotably mounted on doorframes. In such a case, one section consists of the door itself, the door or one door leaf, and the other section is the frame section. Also, one of the profiles of the finger protection device may serve as a frame and be firmly anchored in the masonry. The second profile is then attached to the swinging door leaf.

Other advantageous embodiments of the invention are described in the further dependent claims;

Giant. 4 to 11 are cross-sectional views of parts of different sectoral doors with a finger guard device according to the invention with sections in one plane, the sections being formed of different materials in different shapes, using conventional standard profiles.

Figures 1 to 11 show two adjacent sections 1 and 2 of a sectoral door which are separated by an interspace 10. The first section 1 has a main section 3 with an edge section 3c and a recess 5, which is bounded on both sides by the main section 3, respectively. edge section 3c. Also the second section 2 has a main section 4 with an edge section 4c and a recess 6.

Sections 1 and 2 are articulated hinges, not shown, which are attached to the main sections 3 and 4 and are thus pivotable relative to one another about the axis 3.

The edge sections 3c and 4c shown from the main sections 3 and 4 in the direction of the intermediate space 10 are shown in FIGS. They are thinner than the main sections 3 and 4, so that behind the edge sections 3c and 4c recesses 5, ...

The finger protection Z profile and the cover profile 8 (if installed) are. are arranged in recesses 5 and 6 beyond the edge sections 3c and 4c. As a result, the profiles 2 a; 8 seen from the front side of the sectoral door only by the interspace IQ. Profiles 2 and 8 do not extend towards the rear side through the main sections 3 and 4.

The finger protection profile 2 comprises a circular arc-shaped guard section 2a, a fastening section 2b, a contact surface Zg and a connecting section Zh. The cover profile 8 shown in FIGS. 3 to 11 consists of a cover section 8a curved in a circular arc and a fastening section 8b.

* 1

The main sections 3 and 4 of sections 1 and 2 shown in FIGS. 1 to 3 are provided with a hat-shaped profile 3b and 4b, which is covered on the front side of the sectoral door with a metal lining 3a and 4a. At the edge sections 3c and 4c, the metal paneling 3a and 4a is bent around the edge of the hat-shaped profile 3b and 4b. The flange-shaped attachment section 2b of the finger protection profile 2 is provided with attachment holes 2c for attaching the finger protection profile 2 to the hat-shaped profile 3b. The finger protection profile 2 abuts in the attachment section 2b and in the non-curved contact surface Zg on the hat-shaped profile 3b. A hollow space 11 is formed between these surfaces in which, for example, the screw head can be located. _;

The finger protection profile 2 shown in FIGS. 1 and 2 further has three rubber sealing flaps 2d, Ze and Zf, which are arranged on the protective section 2a, which has the shape of a circular arc. The flap Zd located at the end of the guard section 2a extends in all the swivel positions of the sectoral door into the hat-shaped profile 4b of the adjacent section 2 and the flap Zf into the edge section 3c of the first section 1. second section 2.

In Fig. 1, the sections 1 and 2 are arranged coplanar, thus in a position in which the major planes of the sections coincide. This happens, for example, with closed sector doors. Interspace IQ. there is a relatively small section and the protective section 2a, which is arcuately curved, substantially completely overlaps with the protruding edge section 4c of the adjacent second section 2.

In Fig. 2 the sections 1 and 2 are deflected. Such a position occurs, for example, when opening the door for those sections that are currently moving from vertical to horizontal. The interspace 10 is here relatively large and the guard section 2a of the finger protection profile 2 is provided

overlapping approximately only half-way along the edge section 4 of the adjacent second sec-2. The finger can only be inserted into the interspace 10 until it hits the finger protection profile 7. Since the guard section Ta of the finger protection profile 7 is located at a small distance beyond the edge sections 3c and 4c, finger pinching between the edges closing the edge sections 3c and 4c is safely prevented, even if the sections 1 and 2 are again moved to the coplanar FIG.

In Fig. 3, the cover profile 3 having the cover section Sa is fastened by a fastening section Sh shaped as a flange to a hat-shaped profile 4c provided with fastening holes 4d. The sections Ta and Sa, which have the shape of a circular arc in section, of the profiles 7 and S are equidistant from each other. Since the centers of the circular arcs defined by the cross-sections of the sections Ta and Sa lie on the swivel axis 9 of the sections 1 and 2, the equidistant arrangement of the sections Ta and Sa is retained for each swivel position which occurs when a sector gate is used.

AND
