DE8202712U1 - CHASSIS PART OF A DRIVE UNIT FOR GATES, DOORS AND THE LIKE - Google Patents

Description

The invention relates to a chassis part of a drive unit for gates, τΛτβη and the like according to the preamble of the claim 1.

With these chassis parts there is the difficulty of attaching them to the ceiling in such a way that they can be aligned, uir. the functionally appropriate lags to ensure. For example, in the case of a chain drive, the pulley is the one along a rail in two longitudinal strands A chain guided by a rail in the area of the frame or above it, while the chain driven by the motor is attached to the other End area of the rail mounted drive pinion for the chain is geared to a drive motor which - As the drive pinion or the end area of the rail - is held on a housing chassis. This housing chassis must in the wall area, in the example mentioned in the interior ceiling area the garage to be set.

It is the object of the invention to make this latter fastening of the chassis part as easy to handle as possible under assembly conditions to design.

This is achieved according to the invention by the subject matter of claim 1.

According to the invention, therefore, a perforated strip, usually in the form of a metal strip with regularly distributed over its length

Long holes, through the between the webs and the outside of the chassis part bottom and fixed on the housing in this position, for example screwed. It is then very simple, the ends of the perforated strip protruding outward on both sides of the webs around the opposite ends Bend the edges of the webs so that they protrude from the chassis base part. The fitter then only has to remove the outer end regions turn the perforated strip in turn so that it ver ~ current situation advised. By means of a dowel fastening or the like these punched tape end areas can then be attached to the ceiling. Allow the elongated holes of the strip a lateral readjustment of the position of the chassis part on the wall or ceiling,

It is readily apparent that the required distance from the ceiling is ensured by choosing the length of the perforated strip can be, at the assembly site can therefore replace the punched tape or in the respective desired length insert.

In a preferred embodiment, at least one opening engages Perforated strip in an approach which is formed on the outside of the chassis part bottom. Usually one becomes the For the purposes of better definition, provide for two such approaches, each of which engages in an opening of the perforated strip. The approaches are with holes for receiving a fastening screw Mistake. Such bores can in principle also be provided without the approaches or in addition to them. Important is that the perforated strip is held in a certain position by the screw and, in a preferred embodiment, the approaches will. The screws can then be tightened later or, in the event of of the approaches will be used later.

In order to ensure that the screws clamp the punched tape firmly against the chassis part base, these are preferred

provided approaches protruding lower from the chassis part base than the punched tape is thick.

The invention is explained in more detail below using an exemplary embodiment.

The chassis part shown in the drawings is designated as a whole by 1, the chassis part base 2 has two pairs of webs 3, 4 and 5, 6, which are designed to protrude in the shape of a bridge from the outside 7 of the chassis part base 2. Between the outer side plane of the chassis part base 2 and the parts of the webs 3 to 6 that run parallel thereto eyelets 8 formed. These eyelets 8 can be seen in particular from FIG. The chassis part is a total of a cast aluminum part formed, on which the webs 3 to 6 are integrally formed.

As shown in FIG. 1, the webs 3 and 4 are in pairs assigned to one another in such a way that their associated eyelets 8

parallel to the outside 7 and perpendicular to the longitudinal direction of the web are aligned with one another. The bridge pairs 3, 4 and 5, 6 are each arranged at a distance from one another, so that a distance remains free between the webs 3 and 4 or the webs 5 and 6 in which the in the eyelets of the webs 3 and 4 or in those the webs 5 and 6 inserted perforated strips parallel to the outer plane of the chassis part floor.

Where, if the perforated tape is correctly positioned, two Long holes are located, the chassis part base 2 is provided with holes 9, which are positioned in such a way in the event of missing approaches are that after the insertion of screws through the holes 9 of the strip at least against displacements in its longitudinal direction is assured except for one game. After tightening the screws, the respective punched tape is firmly attached to the Chassis part bottom 2 connected.

In the preferred embodiment shown here, lugs 10 are integrally formed on the outside of the chassis part floor 2, which are arranged and dimensioned in such a way that corresponding openings of the perforated strip encompass the approaches after insertion. In the present exemplary embodiment, per perforated strip 11 or in the spacing area between the webs 3 and 4 or and 6 of a pair of webs, two lugs 10 each are provided.

Fig. 3 shows such a punched tape 11 with a row evenly spaced elongated openings 12. A Such strips can be of the required length and, in this respect, any length - for example, of a corresponding one

Fig. 4 shows that the two protrude from the webs to the outside Sections of the perforated strip around the opposite edges of the associated webs from the bottom of the chassis part are bent protruding. It is readily understandable that the webs or the mentioned web edges here in a simple manner serve as a turning aid. In this way, it becomes safe and secure easy-to-use fastening device provided for the chassis part.
