DETAILED DESCRIPTION

[0072] FIG. 1 shows a fastening apparatus 100 for an elevator system. The fastening apparatus 100 comprises a beam 102 to which a drive bracket 104 is fastened. The drive bracket 104 supports a drive 106 which in this case comprises an electric motor 108 and a traction sheave 110 seated on the drive shaft thereof for driving a support means 112. The beam 102 is mounted so as to be slightly elevated on two feet 114. The feet 114 are fastened, for example screwed, to an installation structure of the elevator system, for example a base plate or an installation support in a machine room. Furthermore, the fastening apparatus 100 comprises a support leg 200, as can be seen in the side view in FIG. 2. The support leg 200 is fastened, for example screwed, at the upper end thereof to the drive bracket 104. With the free end thereof, the support leg 200 is supported on the installation structure. The support leg 200 thus serves to provide additional support for the drive bracket 104.

[0073] The support leg 200 can have a support foot 202 at the lower end thereof. The support foot 202 can be fastened, for example screwed, to the support leg 200 at a specific angle, in order to ensure that the support foot 202 rests flat on the installation structure. Alternatively or additionally, the support foot 202 can be screwed to the installation structure.

[0074] Bearing forces can be introduced into the beam 102 via the feet 114. The feet 114 can each be designed as a plate assembly. This is described in more detail below with reference to FIG. 4. The feet 114 are expediently arranged on an underside of the beam 102 facing the installation structure.

[0075] The feet 114 can be arranged at the outer ends of beam 102, as shown in FIGS. 6 and 7, for example. Alternatively, one of the feet 114 can be slightly inwardly offset, as shown in FIGS. 1 and 5, for example.

[0076] The beam 102 can be constructed from two parallel support plates 116 which are connected to one another on their underside via a one-part or multi-part connecting plate 118 to form a rigid support structure. For example, the connecting plate 118 can be welded to each of the support plates 116. The connecting plate 118 can also be part of the feet 114.

[0077] The two support plates 116 can be positioned at a specific distance from one another transversely to a longitudinal direction of the beam 102. The drive bracket 104 can be seated on two parallel longitudinal edges 120 of the support plates 116 and can be displaced along the longitudinal edges 120 in the longitudinal direction of the beam 102. A portion of the drive bracket 104 can be located between the two support plates 116 and can be screwed to each of the two support plates 116.

[0078] The longitudinal edges 120 can be formed, for example, by an outer edge of the support plates 116, which is bent over at right angles.

[0079] In addition, each of the support plates 116 can have a plurality of bores 122 for screwing the drive bracket 104 in different positions in the longitudinal direction of the beam 102.

[0080] As shown in FIG. 1, the drive bracket 104 can include a tower 124 of a defined height and a drive plate 126. The tower 124 can be screwed to the two support plates 116 at the lower end thereof. The drive plate 126 is placed on an upper end of the tower 124. The drive plate 126 supports the drive 106. The electric motor 108 can, for example, be arranged lying on the drive plate 126 and screwed thereto via a suitable motor receptacle 128.

[0081] For example, the drive plate 126 can be welded to the tower 124.

[0082] Similar to the beam 102, the tower 124 can be constructed from a plurality of individual parts in the form of plates or sheet metal parts. The individual parts can be connected to one another, for example by welding, to form a stable box-shaped profile.

[0083] In addition, the fastening apparatus 100 can comprise a deflection roller 130 for deflecting the support means 112. The deflection roller 130 can be arranged rotatably between the two support plates 116. For this purpose, the two support plates 116 can each have a corresponding axle receptacle 132, for example in the form of a bore, which serves to support an axle 134 of the deflection roller 130.

[0084] The axle receptacles 132 can each be arranged above a foot 114, in particular above the foot 114 which is inwardly offset.

[0085] The traction sheave 110 can be positioned at a specific vertical and horizontal distance from the deflection roller 130 by means of the drive bracket 104. Furthermore, the drive 106 is positioned offset to the beam 102 by means of the drive bracket 104 in such a way that the traction sheave 110 and the deflection roller 130 rotate in a common plane.

[0086] For safety reasons, the support means 112 can be at least partially surrounded by a channel 136. The traction sheave 110 can also be at least partially surrounded by a traction sheave housing 138. The deflection roller 130 can also be at least partially surrounded by a deflection roller housing 140.

[0087] FIG. 3 shows the support leg 200 in a length-adjustable variant having an outer part 300 and an extendable inner part 302 which is arranged in the outer part 300 so as to be displaceable. The outer part 300 can have a plurality of latching openings 304 in the longitudinal direction thereof, which are used to latch the two tubes 300, 302, for example by screwing.

[0088] In contrast to FIGS. 1 and 2, the deflection roller 130 is installed in a suspended manner on the support plates 116 in this case, as will be described in more detail below with reference to FIG. 5.

[0089] FIG. 4 shows an enlarged representation of a foot 114 from FIGS. 1 to 3. The foot 114 is designed in the form of a plate assembly 400 made up of the connecting plate 118 and a fastening plate 402.

[0090] The connecting plate 118 can protrude beyond the support plates 116 on both sides, at least in the region of the foot 114, i.e., be significantly wider than a distance between the two support plates 116 in the transverse direction of the beam 102.

[0091] The fastening plate 402 can in turn be significantly wider than the connecting plate 118 and thus protrude beyond the connecting plate 118 on both sides.

[0092] The connecting plate 118 can be screwed to the fastening plate 402 by means of two connecting screws 404, for example. The fastening plate 402 can be screwed to the installation structure by means of two fastening screws 406, for example.

[0093] In order to increase the height of the plate assembly 400 without increasing the thickness of the fastening plate 402 and/or the connecting plate 118, the plate assembly 400 can additionally comprise an intermediate element 408 which is arranged between the fastening plate 402 and the connecting plate 118.

[0094] For example, the plate assembly 400 can have a left intermediate element 408a and a right intermediate element 408b, which elements can be arranged next to one another. The left intermediate element 408a can be placed opposite a left support plate 116a. The right intermediate element 408b can be placed opposite a right support plate 116b.
