The invention relates to a sectional door.

In DE 103 29 798 a sectional door is described which has a plurality of sections, which are arranged in the closed state of the sectional door on each other substantially in a plane, wherein the sections at least at one side edge by means of a

Section guide device are guided. Two in the closed state of the sectional door superimposed sections have at their mutual contact edge matched profiles particular deep tongue and groove profiles, whereby a high tightness of the door achieved in the closed state and heat, noise and dust penetration can be prevented. In order to separate two adjacent sections when opening the gate, separating devices are provided which, when opening the door, move apart the sections in the plane extension of the sectional door.

A sectional door with separating device is also known from DE 102 10 247.

Other doors and components of such gates are known from DE 197 26 156 Al, DE 26 23 359 B2, DE 196 52 577 Al, DE-GM 19 82 024 and DE-PS 01 86 128.

It has been found that sectional doors according to the prior art can have a high degree of wear depending on the field of use. The invention has for its object to provide an improved sectional door available. In particular, a sectional door is to be provided, which has less wear and a smoother running.

The solution of this object is achieved according to the invention with the features of claim 1.

According to the invention, in a sectional door having at least a first and a second section, wherein the sections are arranged in the closed state of the sectional door over each other substantially in a plane, wherein the sections are guided at least at one side edge by means of at least one section guide device and by means of at least a separator when opening the sectional door in the plane of the sectional door are moved apart, provided that at least one spring device is provided on the first section, which exerts in the plane of the sectional door acting in Auseinanderrückrichtung bias on one of the first section associated bearing device. By the spring device, the separating device is relieved, which has a quieter run and less wear.

Preferably, the spring device is arranged on the respective section. In coordination therewith, furthermore, the bearing device is displaceable relative to the section and is guided by the respective section guide device. Due to this special spatial distribution, it is possible to use powerful spring devices without much effort, and it is also possible to keep the bearing device small, whereby for the lateral guide devices only little space is needed.

In principle, the invention allows a one-sided guidance of sections, wherein the sections are then held in the manner of Kragarmen. Preferably, however, a symmetrical mounting of the sections, each having a left and a right section guide device, which are formed substantially symmetrical to each other and cooperate with correspondingly symmetrical devices formed on the sections, wherein the left and right section guide devices and the devices with respect to each other Sections face each other.

According to a particularly preferred embodiment of the invention, it is provided that the spring device has at least one helical spring, since helical springs are robust and wear-resistant. The use of gas springs is compared to something more expensive, but gas springs tend less to noise.

Preferably, in the closed state of the sectional door superposed sections of the sectional door according to the invention have at their mutual contact edge matched profiles, in particular deep tongue and groove profiles. Such profiles effectively reduce heat, sound and dust penetration and also ensure in the closed state of the sectional door for its stiffening. Further advantageous embodiments and modifications of the invention will become apparent from the dependent claims and from the description in conjunction with the drawings.

The sectional door 10 according to the invention, which is shown and explained in FIGS. 1 to 6, has four sections, namely a first section 12, a second section 14, a third section 16 and a fourth section 18. The sections 12, 14, 16, 18 are in a closed state of the sectional door 10 as shown in Fig. 2 in a common plane. In an opened state (FIG. 3) of the sectional door 10, the sections 12, 14, 16, 18 are upright next to one another in one

Section receiving device 20 mounted, whereby a wall opening (not shown) is completely released.

As can be seen in particular from FIG. 3, the sections 12, 14, 16, 18 each have a spring 32, 34, 36, 38 on their upper upper edge 22, 24, 26, 28, which extends essentially horizontally when installed closed state in correspondingly formed grooves 42, 44, 46, 48 of the respectively adjacent section 12, 14, 16, 18 immerse, with the Figs. 2b and 2c reveals that the spring 34 of the second section 14 is immersed in the groove 42 of the first section 12, the spring 36 of the third section 16 is inserted into the groove 44 of the second section 14 and the Spring 38 of the fourth section 18 is inserted into the groove 46 of the third section 16. The tongue and groove profiling of the sections 12, 14, 16, 18 are preferably standard profiles, as they are found on panels for wall structures. Such panels, which are offered for example by the company Kingspan, are used in the present case as sections.

The sections 12, 14, 16, 18 are guided at their two side edges, of which in FIG. 1 only the right side edges 52, 54, 56, 58 are shown for the sake of simplicity, by means of sectional guide devices 62, 64, 66, 68 mirror-symmetric sectional guide means (not shown) are disposed on the opposite left side edges (not shown).

The section guide device 62, 64, 66, 68 are guided in the region of a door opening by means of a front rail to be fastened to the building 70 and a rear rail 72, wherein the front rail 70 has a guide groove 74 and the rear rail 72 has a guide spring 76. To the

Sectional guiding devices 62, 64, 66, 68 are provided with corresponding profilings, which are omitted in FIG. 1 merely for the sake of simplicity of illustration. The with the guide grooves 74 of the front rails 70 and guide springs 76 of the rear rails 72 cooperating profiles of the

Sectional guide devices are explained in FIGS. 2 d and 4, it being apparent from the bottom section 18 that their section guide device 68 has an engagement spring 78 and an engagement groove 79. This situation is shown in Fig. 4 by the right side edges. However, it is mirror-symmetrical also on the left side edges, not shown. Further, engagement springs and engagement grooves are also found on the section guide devices 62, 64, 66 of the first section 12, the second section 14, and the third section 16. On the section guide devices 62, 64, 66, the engagement spring and engagement groove in FIG Reference numerals 78 ', 78''and 78 ^' '' and designated by the reference numeral 79 ', 79''and 79 ^' ''.

For the articulation of the sections 12, 14, 16, 18 to the section guide devices 62, 64, 66, 68 bearing devices 82, 83, 84, 85, 86, 87, 88, 89 are provided, which are also found on the left side edges and the function of which results from the synopsis of FIGS. 1 and 6.

The bearing devices 82, 83, 84, 85, 86, 87, 88, 89 are flat steel or plastic tongues, which are inserted through the respective section guide device and in a formed in the respective section, laterally open slot 92, 93, 94, 95, 96, 97, 98, 99. In addition to these storage devices bearing pins 19 are still provided which firmly in the respective section 12, 14, 16 and anchored in the section guide device in associated Lagerbolzen- slots 91 are performed.

From Fig. 6 it can be seen that on the bearing devices 82, 83, 84, 85, 86, 87, 88, 89th

Spring devices 102, 103, 104, 105, 106, 107, 108, 109 are supported, wherein the spring devices are formed as coil springs.

The section guide devices 62, 64, 66, 68 also further comprise separating devices 112, 114, 116, 118, which are provided on the left side edges as shown on the right side edges.

The separating devices 112, 114, 116, 118, which are constructed to be identical to one another, will be explained below with regard to their structure with reference to the separating device 116 shown in FIGS. 5 and 6. Elements of the separating devices 112, 114 corresponding to those of the separating device 116 have the same reference numerals in the drawings, but are indicated by '' ''. At the bottom section 18 can be dispensed with a separating device 118 and spring devices 108, 109, because this section is to be separated from any subsequent.

The separating device 116 has a fixed bolt 120, which at the section 16 with a

Fixing device 122 is attached. By means of the fixing device 122, forces can be transmitted in a vertical direction to the section 16 via the fixed bolt 120, with the fixed bolt 120 dimensioned in this way is that a bending of the bolt occurs only to a negligible extent.

The fixed pin 120 fixed to the section 16 protrudes through the section guide device 66, to which end the section guide device has a separating slot 124. On the fixed pin 120 engages a power transmission plate 126 at. These

Power transmission tab 126 is rotatably mounted about the longitudinal axis of the fixed bolt 120, wherein the rotational movement about the longitudinal axis of the fixed bolt 120 due to the kinematics of the sectional door 10 results.

At the bearing opening 128 for the fixed bolt opposite end of the power transmission plate 126 is a second bearing opening 130, said second bearing opening 130 receives a roller shaft 132.

On the roller axle 132, a power transmission roller 134 is arranged, which laterally - as shown in Fig. 4 - protrudes from the region of the section guide device 66.

The roller shaft 132, which is mounted in the second bearing opening 130, projects into one in the

Sectioning device 66 formed in this separating gate opening 136. This separating gate opening 136 extends substantially transverse to the longitudinal extent of the section guide device 66, and it has a slight curvature. The curvature is dimensioned so that in the extended (separated) position of the force transmission plate 136 (Figure 3a), the roller axis in the end position (in the drawing) is kept to the left and does not shift unintentionally.

The function of the sectional door 10 according to the invention according to the preferred embodiment is the following:

In the closed state of the sectional door 10 in Fig. 2, the sections 12, 14, 16 and 18 are superimposed, wherein due to the weight of the sections, the spring devices 102 to 109 are compressed.

If the sectional door is to be opened, an upward force is introduced only at the lowermost section 18, e.g. with a chain or a toothed belt (not shown) can happen. Due to this force, the section guide devices 62, 64, 66, 68 in the front and rear rails 70, 72 slide upwards. As a result of this movement, the uppermost, first section 12 reaches in the region of the section-receiving device 20.

The section receiving device 20 has an abutment device 140, wherein the

Abutment device 140 essentially consists of a pressure plate 142, on the left and right abutment guide grooves 144 are formed, the contour of the guide groove 74 of the front rail 70 corresponds.

The abutment plate 142 is guided left and right in each case an upper bearing track 146 and a lower bearing track 148, wherein the bearing tracks have an inclination, such that the abutment plate 142 due to the Gravity - optionally supported by a motor - occupies a position in the closed state of the sectional door 10, in which the abutment guide grooves 144 represent a continuation of the guide grooves 74 of the front rails.

When the uppermost section 12, as shown in Fig. 2a, in the area of the section receiving device 20, the power roller 134 is immersed in a force introduction track 150 of the section receiving device 20. The force introduction track 150 is curved in such a way that a force extending transversely to the section of the sections is exerted on the power transmission roller 134, whereupon the force transmission roller 134 together with the roller axis 132 is displaced in the separating link opening 134 '. As a result, the power transmission link 126 'is pivoted about the fixed bolt 120', and due to the geometric relationship, the fixed bolt 120 'is displaced in the separation slot 124', resulting in the lift D shown in FIG.

The spring devices 102, 103 support this

Operation, because the spring devices are based on the storage devices 82, 83 on the one hand and the section 12 on the other hand. With the power roller 134 and the power transmission tab 126 and the fixed bolt 120 is therefore no longer the entire weight of the section 12 to raise, making the run calmer and wear is less.

The spring devices 102, 103, 104, 105, 106, 107, 108, 109 are dimensioned differently to the different position of the individual sections 12, 14, 16, 18 in the sectional door 10 account.

The spring devices 102, 103 of the uppermost section 12 are dimensioned to only assist in separating the uppermost section 12 from the subsequent section 14 so that a force is transmitted over the entire displacement path of the roller shaft 132 thereon. In contrast, the spring devices 104, 105, 106, 107 are dimensioned so that the respective sections 14, 16 initially relative to the associated

Initially, the section guide device 64, 66 is practically self-lifting when the load of the overlying section has been removed by insertion into the section receiving device 20. Therefore, of the power roller 134 via the roller axis 132 on the

Force transmission tab 126 in a first, right in Figure 3a region of the separating link opening 136, 136 ', 136' ', which extends approximately to the center plane, virtually no force to transmit, which reduces the closure, because that is noted at this point , the unfavorable lever position in which the

Power transmission link 126 is initially located (Figure 5), is particularly susceptible to wear. By means of spring devices 102, 103, 104, 105, 106, 107, which have a non-uniform force distribution over their drawing path, a fine adjustment for reducing wear can be carried out in a sectional door according to the invention.

With respect to the aforementioned separating devices, it is shown in FIG. 1 that the section guiding devices 62 and 64 are still in mutual contact, whereas the sections 12 and 14 are already separated. Has the power roller 134 'together with the associated roller axis 132' reaches the left end of the separating link opening 136 shown in Fig. 2a, the remaining of the power roller 134 'in the force introduction track 150 causes a lateral displacement of the first section 12 together with the associated

Section guide devices against the abutment plate 142. The force introduction track 150 has in its lower part a slightly curved course and it goes into a support track 151 on. That is, a section initially separated from the subsequent sections and laterally offset is held in the carrier track 151 by the power roller.

At this point, it should be noted that the lateral displacement of the sections 12, 14, 16 is staggered over time, since the displacement process is always triggered only with the entry of the power roller 134 in the force introduction track 150.

The displacement is assisted by the subsequent second section 14, at the top of the

Sectioning device 64 of the second section 16 an upper threading contour 152 is provided which cooperates with a formed on the section guide device 62 of the first section 12 lower contouring 154. Corresponding threading contours are also found on the further sections.

If the first section 12 together with the associated section guide devices 62 laterally offset, the engagement grooves of the first section guide device for the subsequent second section form a guide, such as they have previously been formed by the abutment guide grooves 144 for the engagement spring 78 'of the section guide device 62 of the first section. This continuous relationship is apparent in particular from FIG. 3a.

If the sectional door 10 is to be closed, the lifting force on the lowermost section 18 is switched off, for example by loosening a chain. The lowermost section descends due to gravity or braked controlled. When the lowermost section has left the position shown in FIG. 3 in the section-receiving device 20, the abutment device 140 forwards the third section 16, which is then likewise shut down. This process is repeated until all sections, in the present case, the second section 14 and the first section 12 are shut down.
