Description

The invention relates to a method for installing a garage door.

Garage doors to which the present invention relates are designed as tension spring doors and as overhead doors, the garage door having a door leaf consisting of articulated panels which is movably mounted between two profiles and can thus be moved between an open position and a closed position . The term overhead door means that the door leaf is mounted in an overhead position in its open position in horizontal sections of the profiles. In the closed position, the door leaf is supported between vertical sections of the profiles and thus closes the door opening of the garage, with the lower edge of the lower, first panel resting on the floor of the garage.

The term tension spring door means that a weight compensation unit with a tension spring is provided on at least one of the profiles. The prestressing force generated by the tension spring opposes the weight of the door leaf, with the prestressing force and the weight being at least approximately the same. The door leaf is kept in balance by this weight compensation unit, so that the door leaf can be moved without great effort and remains in a set position.

The installation of known garage doors is carried out in such a way that the panels are first mounted successively in the area of the vertical sections of the profiles and are connected to one another in an articulated manner.

An operator then has to manually push the door leaf up into the open position in order to then mount the or each tension spring of the weight compensation unit, in particular to connect it to a traction means formed by a cable that is coupled to one of the panels. This is necessary because the traction means can be installed in the open position without the full force acting on it.

The disadvantage here is that the operator has to apply a force corresponding to the weight of the door leaf in order to slide the door leaf into the open position. Since the door leaf is very heavy, this often requires several operators.

the WO 2007/124576 A1 relates to a garage door with a door leaf that can be moved between an open position and a closed position and with at least one weight compensation unit that has a tension spring, the door leaf having a plurality of articulated panels that are guided between two profiles. A profile is provided with a recording unit which is firmly connected to the profile and has a plurality of recordings arranged one behind the other in the longitudinal direction of the profile. By fastening one end of the tension spring in different receptacles, the tension spring is mounted on the profile with different pretensioning forces. A locking element is arranged on the receiving unit.

the WO 2004/083581 A1 relates to an overhead sectional door whose door leaf consists of slats connected to one another in an articulated manner. In this case, lateral tension springs are arranged, which act on the door leaf via a tension element in order to support its lifting. Each of the laterally arranged tension springs has at least one plastic or rubber spring.

the DE 20 2017 104 052 U1 relates to a running rail arrangement for a door, in particular a sectional door, comprising a rising running rail which is connected to a door frame either directly or with the interposition of a console, and an upper running rail which extends at an angle to the rising running rail. Furthermore, a weight compensation device is provided which has a cord-like traction means and at least one elastic spring element which is arranged in the area of the upper running rail and at least partially extends parallel to it, which has a door leaf via the traction means and a roller arranged on the spring element and which deflects the traction means can be kinematically coupled. At least one end of the traction means is fixed, in particular releasably, to an adjustment device arranged on the door frame and/or the bracket, with the adjustment device being designed to adjust the position of the end of the traction means, in particular in relation to a vertical direction, and thus the tension of the to change spring element.

The object of the invention is to simplify the installation of a garage door of the type mentioned at the outset.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the dependent claims.

The invention relates to a method for installing a garage door with a door leaf movable between an open position and a closed position and at least one weight compensation unit having a tension spring, the door leaf having a plurality of articulated, between has panels guided between two profiles, comprising the following method steps: Mounting a prestressed tension spring on one of the profiles, one end of the tension spring being fastened in one of several receptacles, arranged one behind the other in the longitudinal direction of the profile, of a receptacle unit firmly connected to the profile in such a way that the pretensioning force the tension spring is less than the weight of the garage door; assembling a first panel to the profiles, the first panel being supported by spacers above the closed position; Coupling the first panel to the tension spring by means of a traction mechanism, the traction mechanism being fixed in a locking position on a locking element on the receiving unit; Installation of the further panels on the profiles, with the installation of the last panel with removed spacers, the door leaf being moved into the closed position by its weight exceeding the prestressing force and thereby the traction means being automatically released from the locking position; Manually moving the door leaf to the open position; Fastening the end of the tension spring in a further receptacle of the receiving unit, so that an increased pretensioning force of the tension spring is obtained, which corresponds at least approximately to the weight of the door leaf.

The basic idea of the invention is to mount the factory-preloaded tension spring of the counterbalance unit at the beginning of the installation of the garage door, namely already when the first panel of the door leaf is mounted between the profiles of the garage door. Spacers ensure that the first panel is above its position, which corresponds to the closed position. Thereafter, the tension spring is connected to a traction means, which is preferably formed by a cable. In general, several cables can also be provided.

The end of the or each tension spring is advantageously fixed by means of a fastener mounted in a receptacle of the receiving unit, and guide means for the tension means are provided at the other end of the tension spring, with a free end of the tension spring being connected to the profile via the tension means.

It is essential here that the receiving unit with the arrangement of spaced receptacles is provided on the profile on which the weight compensation unit is provided, with different values of the prestressing force of the tension spring being predeterminable by fastening one end of the tension spring in different receptacles. According to the invention, the prestressing force is specified during the installation of the garage door in such a way that it is less than the weight of the door leaf.

It is also essential that a locking element is mounted on the receiving unit, which holds the traction means in a locking position, while after the assembly of the first panel the other panels are assembled until the door leaf is complete.

When the spacer is removed, the door leaf then automatically moves down into the closed position, since the pre-tensioning force was set to be smaller than the weight of the door leaf. According to the invention, the locking element is designed in such a way that the traction mechanism moves automatically out of the locking position in this downward position. The tension spring is now ready for operation.

The spacers are advantageously removed after the first panel has been coupled to the tension spring with the tension means.

In the next process step, an operator pushes the door leaf from the closed position into the open position. Since the prestressing force counteracts the weight, the operator only has to apply a force that corresponds to the difference between the prestressing force of the cycles and the weight of the door leaf. Since the prestressing force can approximately correspond to the weight of the door leaf, the operator only has to exert a small amount of force for this purpose.

The prestressing force is advantageously reduced by an amount ΔF compared to the weight of the door leaf, ΔF being smaller than the weight of a panel.

The operator must therefore apply a force that is less than the weight of a single panel.

If the door leaf is retracted into the open position, the operator only needs to fasten one end of the tension spring in another receptacle of the receiving unit, so that an increased prestressing force is obtained which at least approximately corresponds to the weight of the door leaf.

The door leaf is then balanced with the weight compensation unit and the garage door is ready for use.

The installation of the garage door according to the invention requires only a small number of process steps and can be carried out easily and quickly. In particular, it is advantageous that the door leaf can be brought from the closed position into the open position with very little effort, which can be easily applied by just one operator.

According to a particularly advantageous structural configuration, the or each receiving unit is in the form of a ladder, the recesses of which form the receptacles.

In general, the receiving unit can also be part of the profile itself, in that holes forming these receptacles are machined.

Further advantageously, the or each locking element has fork-shaped locking segments.

Depending on the area of the locking segments of the locking element in which the traction mechanism is guided, it is locked on the locking element, ie in a locking position, or it is guided in a movable manner.

According to a particularly advantageous embodiment, a clamping element is provided on the traction device, by means of which the traction device is secured in position on the locking element in the locking position.

The clamping element is preferably designed as a pinch clamp. In general, the clamping element can also be formed from a sleeve with a clamping screw or the like.

According to a particularly advantageous variant of the invention, after the traction mechanism has been released from the locking position, the locking element is detached from the receiving unit automatically or by manual intervention.

The locking element thus no longer interferes with the movement of the traction mechanism. For this purpose, the or each locking element can advantageously be releasably connected to the receiving unit by means of a hook or a latching means.

In the first variant, the locking element is released automatically from the receiving unit; in the second variant, it is released by manual intervention.

According to an alternative variant, the locking element remains on the receiving unit after the traction mechanism has been released from the locking position.

It is then advantageous that the locking element is formed in one piece with the receiving unit.

In the simplest case, only one weight compensation unit is arranged on one of the profiles in the garage door according to the invention. Then one of the tension springs of the weight compensation unit has to compensate for the weight of the door leaf.

A weight compensation unit is advantageously provided on each profile, with the weight compensation units being of identical design.

In this case, the pretensioning forces of the two tension springs of the weight compensation units are dimensioned in such a way that together they compensate for the weight of the door leaf.

1 1 schematically shows an exemplary embodiment of the garage door 1 according to the invention. The garage door 1 has a door leaf 2 with an arrangement of panels 3a-3d connected in an articulated manner. In the present case, the door leaf 2 has four panels 3a-3d. Of course, a different number of panels 3a-3d can also be provided. The door leaf 2 is guided in two profiles 4 and can thus be moved between a closed position and an open position. The profiles 4 are identical and mirror-symmetrical.

For guidance in the profiles 4, guide rollers 6 mounted on axes 5 are provided on the opposite edges of the panels 3a-3d, as shown in FIG 5 indicates.

1 shows the garage door 1, in which the door leaf 2 is retracted into the closed position. In the closed position, the door leaf 2 is located between vertical sections of the profiles 4, so that the door leaf 2 closes the door opening of the garage. The bottom edge of the bottom, first panel 3a of the door leaf 2 sits on the floor of the garage.

In the open position, the panels 3a - 3d of the door leaf 2 are mounted between the horizontal sections of the profiles 4 . The door leaf 2 is then in an overhead position, as a result of which the garage door 1 forms an overhead door.

2 shows one of the profiles 4 of the garage door 1, namely its vertical section in an overall view. the 3 until 5 show sections of this profile 4.

How out 2 As can be seen, a weight compensation unit with a tension spring 7 is provided on this profile 4, ie the garage door 1 is a tension spring door. Alternatively, a gas pressure spring can be provided. Another weight compensation unit of this type, designed identically to this, can also be provided on the other profile 4 . In the following, the case is discussed in which a weight compensation unit is only provided on one profile 4 .

The tension spring 7, which is pretensioned at the factory and delivered in this form, has a deflection roller 8 at its upper end for guiding a cable 9 forming a traction means. Another deflection roller 10 is mounted on profile 4. The free ends of the cable 9 are mounted on a fastening element 11 on the profile 4.

In the area of the lower end of the tension spring 7 there is a receiving unit 12 which is fastened to the profile 4 and which in the present case is designed as a ladder. The recesses in the conductors form a sequence of receptacles 13 arranged one behind the other at a distance in the longitudinal direction of the profile 4. The receptacles 13 are of identical design and form an equidistant row arrangement.

A fastener 14 is attached to the lower end of the tension spring 7 . The fastening means 14 can optionally be releasably fixed in one of the receptacles 13 of the receptacle unit 12 . Depending on the receptacle 13 in which the fastener 14 is fixed, a different prestressing force of the tension spring 7 is obtained, ie the prestressing force of the tension spring 7 can be adjusted in discrete stages with the receptacle unit 12 .

The rope 9 forms a loop at the lower end, which is guided in a guide element 15 . The guide element 15 has a bore into which an axle 5 of a panel 3a-3d can be inserted, whereby the cable 9 is coupled to the panel 3a-3d, as shown in FIG 5 indicates.

How from the 4 and 5 As can be seen, a locking element 16 is provided which can optionally be fixed in one of the receptacles 13 . In the present case, the locking element 16 has a latching means 17 for fixing to the receiving unit 12 . In general, other attachments can also be provided, such as screw or clamp connections.

The locking element 16 has a flat base body that rests against the receiving unit 12 and from which a plurality of fork-shaped locking segments 18 protrude. Is how particular 5 shows the cable 9 inserted into the spaces between the locking segments 18, the cable 9 is in a locking position, that is, it is fixed in position.

the 6 until 8th show variants of the locking element 16.

The embodiment according to 6 differs only with regard to the geometry of the locking segments 18 from the embodiment according to FIG 5 .

In the embodiment according to 7 the locking element 16 has a plurality of locking segments 18 arranged one above the other. In this case, the locking element 16 is only hooked into a receptacle 13 of the receptacle unit 12 with a hook (not shown).

In the embodiment according to 8th are the components of the locking element 16, that is, the locking segments 18 are part of the receiving unit 12 and formed in one piece with it.

The installation of the garage door 1 according to the invention is explained below.

At the beginning of the installation, the bottom panel 3a is stored in the profiles 4, as in 9 shown, which are then guided in guide rollers 6 of the panel 3a in the profiles 4. The panel 3a is placed on the spacer 19 so that the panel 3a is above its position in the closed position of the door leaf 2, in which the lower edge of the panel 3a would rest on the floor of the garage.

In this raised position of the panel 3a, the weight compensation unit is integrated with the tension spring 7 in the profile 4. Furthermore, the rope 9 as in the 2 until 4 shown assembled. Finally, the guide element 15 is applied to the axle 5 so that the cable 9 is mounted on the first panel 3a. This assembly takes place without force, since the cable 9 is not subjected to any force.

The cable 9 is secured in position on the locking element 16 in the locking position.

The fastening means 14 at the lower end of the tension spring 7 is introduced into a receptacle 13 of the receptacle unit 12, in which a pretensioning force of the tension spring 7 is obtained which is less than the weight of the door leaf 2.

In the present case, the difference ΔF between the weight of the door leaf 2 and the pretensioning force of the tension spring 7 is smaller than the weight of a panel 3a-3d, with the pretensioning force being 80% of the weight of the door leaf 2 in the present case.

After this assembly step has taken place, the spacers 19 can already be removed, since the cable 9, which is secured in position in the locking position of the locking element 16, means that the panel 3a in the in 9 shown position is held.

The second panel 3b is then mounted between the profiles 4 so that its guide rollers 6 are guided in the profiles 4 . In this case, the panel 3b is connected in an articulated manner to the panel 3a.

The panel 3c is then installed in the same way.

The three panels 3a - 3c mounted in this way still have a total weight that is less than the prestressing force, so that the bottom panel 3c is still in the in 9 shown position remains.

Finally, the fourth panel 3d is correspondingly mounted between the profiles 4 and articulated to the panel 3c.

Now the weight of the door leaf 2 is greater than the biasing force of the tension spring 7 and the door leaf 2 lowers down into the closed position.

In principle, the spacers 19 could also be removed after the assembly of the second, third or fourth panel 3b-3d in order to obtain the same effect.

The downward movement of the door leaf 2 automatically releases the cable 9 from the locking position of the locking element 16 .

In the embodiments of 2 until 5 and the 6 an operator then releases the latching means 17 of the locking element 16 and removes the locking element 16 from the receiving unit 12 so that it does not interfere with the movement of the cable 9 .

In the embodiment of 7 the locking element 16 is released from the receiving unit 12 automatically by the hook being released from the receptacle 13 of the receiving unit 12 .

In the embodiment of 8th the locking element 16 remains on the receiving unit 12 since the locking element 16 is formed in one piece with the receiving unit 12 .

In the next step of the installation, the operator pushes the door leaf 2 from the closed position into the open position. This can be done by just one operator without great effort, since he does not have to apply the entire weight of the door leaf 2, but only the difference ΔF between the weight and the pretensioning force of the tension spring 7, since this is already installed in the profile 4.

The operator then inserts the fastener 14 at the lower end of the tension spring 7 into another, lower-lying receptacle 13 of the receiving unit 12, so that an increased pretensioning force of the tension spring 7 is then obtained, which corresponds at least approximately to the weight of the door leaf 2. The door leaf 2 is thus balanced by the weight compensation unit. The garage door 1 installation is complete and the garage door 1 is ready for use.

the 10a and 10b show an advantageous further development of the embodiment of FIG 1 until 5 .

10a shows a section of the profile 4 with the locking element 16, which is mounted in a receptacle 13 of the receptacle unit 12 (not shown).

This arrangement corresponds to the arrangement of 2 until 4 , The locking element 16 in turn having locking segments 18 .

At its lower end, the cable 9 again forms a loop which is guided in the guide element 15 .

Two clamping elements in the form of pinch clamps 20 are arranged on the cable 9 . The pinch clamps 20 form tubular bodies which enclose the cable 9 and which are firmly connected to it ( 10b ).

As 10a shows that when the cable 9 is in the locked position, the pinch clamps 20 lie in the spaces between the locking segments 18 of the locking element 16 and thus ensure that the cable 9 is secured in the locked position on the locking element 16.
