EP2381056B1 - Floor guide for a side sectional door - Google Patents

Description

Field of the invention

The present invention relates to a guide mechanism for a door section of a side sectional door, and further to a side sectional door having such a guide mechanism. Corresponding side sectional doors may be, for example, garage doors, industrial doors, access for storage rooms, etc.

State of the art

In the prior art, a variety of side-sectional doors are known, which generally have the advantage over lift gates of being able to move smoothly in a horizontal direction. In this case, the actual opening of the door depends on the particular need, namely, for example, only a gap wide or completely.

Usually Seitensektionaltore be suspended in the ceiling of the garage or the upper edge of the door opening. Here, attached to the sections of the door rollers are rotatably guided on a rail. In the lower part of the sections, various constructions are known to guide the door along a guide on the ground. In addition to the function of guiding the door sections along a predetermined path, the guides on the ground should continue to protect against burglary, among other things. For example, a door section should not be able to be pivoted or pushed inside the garage. However, the door leaf is not supported in the vertical direction on the ground, but it depends exclusively.

As a variant of such a floor guide a sectional door, for example, a cross-sectionally U-shaped rail is known. For new buildings such a rail can be integrated (sunk) in the garage floor. Alternatively, in the case of retrofitting, the rail is fixed on the garage floor. At each door section extending in the vertical direction guide rods are provided, at the ends of rollers are rotatably mounted. These rollers are guided inside the U-shaped rail. The axis of rotation extends parallel to the door leaf and the legs of the U-shaped profile of the rail.

However, the bottom rails have the disadvantage that dirt collects in them and possibly limits their function. Next results when retrofitting a bottom rail a significant difference in height between the top of the rail and the garage floor, which is perceived when driving over the bottom rail with a car as unpleasant.

Another state of the art is the German utility model DE 93 18 718 U1 known. This document relates to a side sectional door which is guided on the underside of the door sections by means of projecting guide blocks fixedly connected to the garage door by way of a bar. At the sections of the sectional door, in turn, guide rails are fixed on the underside, which have a U-shaped cross section facing the garage floor. The insides of this U-shaped cross-section touch the already mentioned guide pads and ensure that the respective door section is guided along an intended direction.

However, the bar with the guide blocks is a survey of the garage floor, which is noticeable when driving over the bar and the guide blocks with a car. In addition, results from the guide blocks a irregular floor structure, and further it could come when operating the sectional door for wedging a door section, since each sectional door must be "threaded" from one guide block to another.

Another prior art is the document EP 1 870 549 A2 known. This document also relates to a side sectional door, on the sections of which securement profiles are fixed at the bottom. Such a receiving profile has a receiving groove for a sealing element and a receiving groove for receiving a fixed to the garage floor guide pad. The fixed on the floor guide blocks can be changed by means of a spacer in height. As a result, for example, unevenness of the garage floor can be compensated. However, the guide blocks again result in an uneven floor structure which, if necessary, has a disturbing effect when it is driven over by a passenger car. Also, the adjustment of the height of the guide blocks must be made manually during installation to ensure adequate guidance or burglar alarm.

As state of the art is the DE 197 53 219 A1 known, which relates to a guide device for sliding elements. In order to ensure a good acoustic and thermal insulation, sealing elements, preferably brush strips, are secured in retaining grooves on profiles and on U-shaped parts.

As a further prior art is the DE 296 01 756 U1 known, which relates to a damper for a sliding glass door.

Content of the invention

The present invention has been accomplished in order to solve the aforementioned problems. It is another object of the present invention to provide a guide mechanism for a horizontally movable door section, so that it can be moved easily, and the door section is easy to assemble and low maintenance.

The object of the invention is achieved by a guide mechanism according to claim 1 and a Seitensektionaltor according to claim 8. Further preferred embodiments are described in the dependent claims.

The core idea of the present invention is to provide a guide mechanism for a door section of a side sectional door, which as it were "floats" along a guide rail, while at the same time exercising the guiding function.

For this purpose, a guide mechanism for a door section is provided according to the invention, comprising: a guide element with a holder, for connection to the door section, and a guide, in particular a guide rail, wherein the door section is displaceable along at least part of the guide. The guide mechanism is characterized in that a brush element connected to the holder is provided relative to the holder such that the guide element can be supported by brushing the brush element relative to the guide. The holder of the guide element is attached to a door section, and the guide rail to a floor.

The feature "brush element" or "brush" preferably relates to a tuft-like component. In this case, the brush has a greater rigidity in its direction pointing towards the axial direction than in a direction perpendicular to the axial direction. Thus, the term "brush element" or "brush" also includes, for example, rubber or plastic elements having these properties. Also, in addition to a plurality of brushes, it is also possible for only one brush to be provided on the guide element. Also, the brush element can be attached to the holder both as a separate component, as well as integrally formed therewith.

As a result, the guide element can be moved very smoothly along a guide rail. The brushes are designed so that they support the guide element, can deform flexibly, and yet ensure a guide. If, for example, a transverse force is applied perpendicular to the guide direction, the brushes guide the door section relative to the transverse force. In case of abuse and when exceeding a certain transverse force, the brushes of the brush element deform until the rigid support comes into contact with the guide and blocks the further movement in this direction. In this way, an anti-burglar alarm is provided.

At the same time, the brushes serve to clean the guide during operation, ie the method of the door section. Further, the brushes are compared to rigid contact mechanisms, as known in the art rollers, quiet and largely maintenance-free. The brushes also adapt to the external conditions and can, for example, compensate for slight unevenness in the floor. Furthermore, wedging of the guide element on the guide is avoided.

The brush (s) or brush (s) may provide support in the vertical and / or horizontal directions (opposite the guide). The support in the vertical direction serves primarily to receive the weight of the guide element, so that it does not come into contact with the substrate in a "normal" state, for example, with its holder, in particular when the guide element is relative to the door section or the guide is held vertically displaceable to compensate for larger bumps. The support in the horizontal direction serves primarily to guide along the guide perpendicular to the guide or travel of the door section or in other words to the longitudinal extension of the guide. To realize both functions, one is Inclined position of the brush / -n to the horizontal or vertical provided.

In this case, it is provided according to the invention that the brush element is mounted on the guide element such that the brush of the brush element extends in a direction inclined to the horizontal direction (see above). Thus, the brush against a horizontal or even against a sloping ground lines abut, or insert into an oblique profile of a guide rail.

In a further embodiment, it is provided that a support element of the guide element extends on both sides of the holder connected to it in the horizontal direction. As a result, the guide element is supported balanced against the ground.

Furthermore, it is preferred that the brushes of the brush element or a plurality of brush elements used protrude like tufts from a base. Here, the use of a plurality of brush elements has the advantage that a variety of standard components used and thereby a cost-effective guide mechanism can be formed. The shape of the brushes on the brush elements gives the guide element good sliding properties in relation to the guide.

Incidentally, it is preferable that the brushes of the brush elements point away from each other and from the support member. As a result, the guide element is set up in a special way to engage in a C-shaped profile of a guide rail.

In another embodiment, it is preferred that the brushes have at least two brush elements facing each other. As a result, the guide element is designed for a cross-sectionally T-shaped rail.

Further, a Seitensektionaltor for closing a room, such as a garage or a storage room, part of the present invention, wherein the Seitensektionaltor one, preferably several Torsektion / -en, in an upper region of the space or the upper edge of the opening, for example by means of a Roller mechanism are suspended, and further has a guide mechanism according to one of the preceding variants.

In one embodiment, the guide element is movable in the vertical direction relative to the door section. As a result, unevenness of the soil, which can be expressed in a change in the gap between the bottom of the door section and the ground, be compensated. This function can also be performed independently to the compensation function of the brushes of the guide mechanism. Other variants relate to side sectional doors with a C-shaped profiled rail, or a T-shaped profiled rail.

Detailed Description of the Preferred Embodiments

Hereinafter, two preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The words "below" and "above" in this context refer to sections provided in the vertical direction.

FIG. 1 shows a guide member 1, which, as described in more detail later, is connected to a door section 100 of a side sectional door. The guide element 1 has a cylindrical pin 2 extending in the mounted state in the vertical direction as a holder. The pin 2 is as in FIG. 3 shown connected at its upper end with a Torsektion. At its in the mounted state to the ground facing lower end of the pin 2 is centrally connected to a support member or cross member 3, wherein the cross member 3 extends perpendicular to the pin 2 on both sides. The cross member 3 in turn has two extending in the longitudinal direction of the cross member 3 inner rails 3a as recordings. Opposite the door section 100, the guide element 1 for compensating, for example, unevenness of the floor by the cylindrical axially displaceable.

In the inner rails 3a extending on both sides, a plurality of brush elements 4 are accommodated. A respective brush element 4 in this case comprises a base 4a and brushes 4b accommodated on the base 4a. The base 4a is covered by the inner rail 3a, and the brushes 4b protrude from the inner rail 3a. In the respective embodiment, the brushes are tuft-shaped attached to the respective base 4a.

It is also conceivable that the brushes are integrated in the cross member (3 + 4 as a component possibly provided).

In this case, however, in the present embodiment, the inner rail 3a is respectively configured such that the brush elements 4 protrude with respect to the cross member 3 in an inclined direction on two longitudinal sides thereof. Viewed in cross-section thus results in a gable-shaped structure. If the guide element 1 is placed on the ground, for example, it rests in the region of the tips of the brushes and is supported by the brushes 4b of the brush elements.

In the assembled state, the guide element 1 in the also in FIG. 1 shown bottom rail 10 (guide rail) added. The bottom rail 10 in this case comprises a centrally arranged, C-shaped profile 11, which defines the guide direction for the door sections. Further, the bottom rail 10 includes a curved portion / slope 12, which facilitates driving over the rail with a car. The curved portion / slope 12 is provided in the mounted state facing the exterior of the garage, and thus provides a good visual impression. Further, the bottom rail 10 in the assembled state into the interior of the Garage facing support and mounting area 13 to connect the bottom rail 10 with the ground. For this, as in FIG. 4 to see, for example, a screw conceivable. In an alternative embodiment, unlike the flat embodiment shown here, the support and mounting region 13 could also be formed as a bevel.

Next is based on FIG. 3 the assembled state of the guide member 1 described. Thus, a lower mounting section 101 is provided on a door section 100 in the lower area of the gate end 103. This lower mounting portion 101 forms a cylindrical guide to receive the pin 2 of the guide member 1. Here, the pin 2 is both rotatably and axially movably received in the lower mounting portion 101. Due to the rotation of the guide of the door section 100 is facilitated by curved portions of the bottom rail 10. Due to the axial mobility in the vertical direction unevenness of the garage floor or height differences can be compensated for in total.

After the guide member is received in the C-shaped profile 11, the guide member 1 is supported by the laterally extending brushes 4b of the brush members 4. *** " The rigidity of the brushes 4b ensures that the cross member 3 does not essentially come into contact with the bottom rail 10, unless an excessive force is applied to the guide element 1. Such a case would be present, for example, in a burglary attempt or the like.

Further, a brush 106 extending longitudinally along the bottom rail 10 is provided at the lower gate end 103. This serves to keep dirt from the outside of the garage away from it. The brush also has the function of sealing. For this purpose, the brush 106 along the Torse section 100 provided and with the bottom rail 10 in contact.

Next is to be discussed in brief words on the suspension of the door section 100. At the upper gate end 104, an upper mounting portion 102 is fixedly connected to the door section 100. The upper mounting portion 102 thereby fixes a roller mechanism 105 to the respective door section 100. Usually, two such roller mechanisms 105 are connected to the respective door section 100. The roller 105a of the roller mechanism 105 is guided on a rail 108, which in turn is fixedly fixed in an upper portion of the garage. Thus, the roller mechanism receives the weight of the door section 100 and ensures movement of the door section 100 in the horizontal direction. On the rail 108, a brush 107 is provided in the present embodiment, which prevents the ingress of dirt in the upper region of the door section 100. Again, the brush (in the upper part) has the function of sealing. For this purpose, the brush 107 is in contact with the door section 100.

Hereinafter, the installation and operation of a sectional door using the guide member 1 according to the first embodiment will be discussed.

The bottom rail 10, which may be formed in one piece or several pieces, is laid and fixed along the floor. For fixing is, for example, a screw, wedging or concreting conceivable. Subsequently, in a still open area, the door sections 100 suspended by means of the roller mechanism 105, which usually have two or more guide elements 1, are "threaded". For this purpose, the guide element is inserted into the C-shaped profile. The rigidity of the brushes 4b ensures that the guide element 1 is supported by the brush elements 4. After the guide members 1 of a door section have been inserted into the floor rail 10, the door section can be smoothly moved in the horizontal direction. Because the guide element 1 is axially movable with respect to the door section 100, height differences, such as unevenness of the garage floor, can be compensated for when the door section 100 is displaced. After the cross member 3 is received in the C-shaped profile, and the pin 2 also extends into the C-shaped profile 11, it is ensured that the door section 100 can not be moved perpendicular to the guide direction. This ensures protection against break-ins. After the guide element 1 is connected via the pin 2 rotatably connected to the door section 100, the door section 100 can be easily moved around curved portions of the bottom rail 10.

Subsequently, all door sections of the side section door are assembled as explained in the previous paragraph. The side sectional door can then be opened and closed in the horizontal direction.

Hereinafter, a second embodiment of the present invention will be described with reference to FIGS Figures 2 and 4 described. Here, only the elements are discussed in more detail, in which the second embodiment differs from the first embodiment. Further, if necessary, the same reference numerals as in the first embodiment are used for corresponding elements and components.

The guide element 20 of the second embodiment likewise has a cylindrical pin 21 extending in the mounted state in the vertical direction as a holder which has at its lower end a cross member 22 (carrier element) extending on both sides in the vertical direction. However, the cross member 22 is wider with respect to the cross member 3 of the first embodiment perpendicular to the guide direction (width direction) designed. Thus, the cross member 22 on two inner inner rails 22a, which are spaced apart in the width direction and facing each other. Further, the inner rails 22a are inclined to a horizontal direction. As in the first embodiment, brush elements 4 are received in the inner rails 22a, which are encompassed and held with their base 4a by the inner rails 22a.

As a result of the fact that the inner rails 22a of the second embodiment are turned toward one another, the brushes 4b of the brush elements 4 accordingly also face one another in the mounted state. The fact that the rails 22a are inclined to each other, the brushes 4b are inclined to each other. When viewed in cross-section, this results in a tip formed by the brushes 4b, but the opposite brushes 4b do not touch each other.

The second embodiment of the present invention further includes a floor rail 30 mounted on a floor. In contrast to the first embodiment, the second embodiment comprises a T-shaped web 31, which defines the guiding direction for the guide element 20 along the garage floor. Further, the floor rail 30 in the outwardly facing portion of the garage includes a curved portion / slope 32 which is formed similarly to the arched portion / slope 12 of the first embodiment. The same applies to the inwardly facing support and mounting region 33 of the bottom rail 30. Again, the mounting portion 33 could be designed in an alternative embodiment instead of a flat area as a slope.

The assembled state of the second embodiment of the present invention will now be described with reference to FIG FIG. 4 described in more detail. Here, the detailed description of the suspension of the door section 100 on the garage is omitted since it is substantially the same as the suspension of the first embodiment.

The lower mounting portion 101 fixedly attached to the door section 100 surrounds the pin 21 of the guide member 20 so that the guide member 20 is both rotatable and axially movable with respect to the door section 100. However, as in the first embodiment, the axial mobility is limited so that the pin 21 can not slip out of the lower mounting portion 101.

According to the design of the second embodiment, the cross member 22 surrounds the web 31 at least in sections, and the brush 4b touch a central region of the T-shaped web 31. Again, it is ensured by the stiffness of the brush 4 b that the guide member 20 is supported by the brush elements 4 and the crossbar 3 or the pin 21 is substantially not in contact with the bottom rail 30.

The following is with reference to FIG. 4 the assembly of a door section according to the second embodiment described.

After the floor rail 30 has been laid and fixed on the garage floor, a door section 100 suspended with a roller mechanism in the upper area of a garage is "threaded" with the guide element attached to the floor rail 30. Usually, such a guide mechanism is provided on a door section. However, a plurality of guide elements may also be provided on a door section, such as, for example, two on the so-called lock section of a sectional door.

For this purpose, the guide element 20 is applied to the T-shaped web 31 in an open region of the bottom rail 30 and moved along the longitudinal extent thereof. Once the door section 100 has been threaded, it can move smoothly in horizontal direction while being guided by the guide member 20 and the bottom rail 30.

The burglar resistance is ensured because in an attempt to move a door section 100 perpendicular to the guide direction, portions of the cross member 22 and the pin 21 come into contact with portions of the bottom rail 30 and such movement is therefore blocked.

The fact that the guide member 20 is supported by the brushes 4b, a smooth movement is possible. After the guide member 20 is movable in the axial direction relative to the door section 100, height differences can be compensated. Due to the rotatability of the guide element 20 relative to the door section 100, a smooth displacement about curved sections of the floor rail 30 is possible.

Of course, it is possible to combine individual elements and features of the two described embodiments with each other in order to obtain further preferred variants. In addition, reference is made to the following design options.

Thus, in the embodiments described above, a multiplicity of brush elements 4 are received in the cross member 3, 22. However, it is of course possible to use a designed as a respective brush element component. The brush elements or the brush element can also be attached directly to the pin 2, 21 and / or be made in one piece with this.

Also brushes are not necessarily only brushes in the classical sense to understand, but it can also be provided, for example, lubricious rubber or plastic elements that have the brush corresponding properties. This concerns one higher rigidity in the axial direction of such a component than in a transverse direction thereto. As a result, a support against a guide is realized, while in "oblique" directions to guide a certain flexibility prevails.

Furthermore, the described embodiments have been described in terms of a nachmontierte bottom rail, which is firmly connected to the ground. Of course, the present invention also relates to floor rails, which are already integrated in the bottom of a garage.

Also, it should be noted that the word "garage" is to be interpreted broadly, and includes not only common car garages, but also industrial doors, doors, windows, fume hoods or other access.

Further, the present invention does not exclude that the door section (s) is (are) only partially guided in a bottom rail 10. Thus, for example, it is possible for a guide to be provided in straight sections, while no floor rail is attached in curved sections. The respective guide element does not fall out of the lower mounting portion 101 of the door section 100 here.

It is also possible, in spite of the axial mobility of the guide element described above relative to the door section, that the guide element is fixed to the door section during assembly or already in advance.
