Linear drive for sliding doors or the like
A linear drive for sliding doors, particularly linear drives based on linear motors. A linear drive, for at least one part which is movable along a movement path, particularly a sliding door leaf, has at least one linear motor for the at least one part. A stator part of the linear motor is received in a receiving profile so as to be prevented from falling out. The receiving profile is constructed to be arranged at a fastening device, which is arranged in turn on the installation side of a wall portion or top portion. Accordingly, the stator part and receiving profile form a module or unit, which can be mounted in its entirety. Therefore, a person performing the mounting can use the receiving profile for mounting, which helps to reduce the risk of damaging the stator part.
1. A linear drive for a part movable along a movement path, comprising:
a linear motor having a stator;
a receiving profile that fixedly retains the stator; and
a fastening device to which the receiving profile is mounted, an installation side of the fastening device is further adapted to be mounted on a wall portion,
wherein the receiving profile comprises projections dividing an interior space of the receiving profile into two receiving spaces,
wherein the stator is received in one of the two receiving spaces and
wherein a rotor part of the linear motor is received and guided in the other of the two receiving spaces,
wherein the receiving profile has a slide-on portion on at least one lateral side thereof.
2. The linear drive according to claim 1 , wherein the slide-on portion has a dovetail cross-sectional shape and extends in longitudinal direction of the receiving profile.
3. The linear drive according to claim 1 , wherein an accessory profile is arranged at a side of the receiving profile remote from the fastening device, the accessory profile is designed to receive accessory devices.
4. The linear drive according to claim 3 , wherein the accessory devices comprise at least one of a locking module, an emergency exit module, an energy accumulator and a sensor module.
5. The linear drive according to claim 1 , wherein the fastening device comprises a suspending profile in which the receiving profile is received and held.
6. The linear drive according to claim 5 , wherein the fastening device further comprises a fastening part which is arranged at least on one of one side of the top portion of a glass pane and the wall portion and at which the suspending profile is fastened, which suspending profile is arranged at the top section of a glass pane or a wall portion.
7. The linear drive according to claim 6 , wherein at least the suspending profile and the fastening part are fastened together by a fastener.
8. The linear drive according to claim 6 , wherein at least the suspending profile and the fastening part are glued together.
9. The linear drive according to claim 1 , wherein the fastening device comprises a suspending profile at which the receiving profile is arranged in a stationary manner.
10. The linear drive according to claim 1 , wherein the receiving profile extends longitudinally and forms a receiving space having a first portion and a second portion, the stator being arranged in the first portion of the receiving space, and
wherein the linear drive includes a rotor longitudinally movably arranged in the second portion of the receiving space.
11. The linear drive according to claim 10 , wherein the fastening device comprises a suspending profile in which the receiving profile is received and held.
12. The linear drive according to claim 11 , wherein the fastening device further comprises a fastening part which is arranged at least on one of one side of the top portion of a glass pane and wall portion and at which the suspending profile is fastened, which suspending profile is arranged at the top section of a glass pane or the wall portion.
13. The linear drive according to claim 12 , wherein at least the suspending profile and the fastening part are fastened together by a fastener.
14. The linear drive according to claim 12 , wherein at least the suspending profile and the fastening part are glued together.
15. The linear drive according to claim 12 , wherein at least one fastener is inserted through corresponding holes in the fastening part, the suspending profile and the receiving profile to mount the linear drive to the one of the top portion of a glass pane and the wall portion.
16. A linear drive for a part movable along a movement path, comprising:
a linear motor having a stator;
a receiving profile that fixedly retains the stator; and
a fastening device to which the receiving profile is mounted, an installation side of the fastening device is further adapted to be mounted on a wall portion,
wherein the receiving profile comprises projections dividing an interior space of the receiving profile into two receiving spaces,
wherein the stator is received in one of the two receiving spaces and
wherein a rotor part of the linear motor is received and guided in the other of the two receiving spaces
wherein an accessory profile is arranged at a side of the receiving profile remote from the fastening device, the accessory profile is designed to receive accessory devices, and
wherein the receiving profile has a first slide-on portion arranged at least on an outer side facing the accessory profile, wherein the accessory profile has, on the side facing the receiving profile, a second slide-on portion, wherein the second slide-on portion is arranged at the first slide-on portion of the receiving profile.
