Abstract

A chain operator housing (1) comprising a barrier member (16) for subdividing the interior of said operator housing (1) into an operator chain compartment, which is open to the exterior, and a drive compartment, which is substantially sealed from the exterior.

Claims

1. A chain operator housing having an interior, comprising:

a barrier member for subdividing the interior of said operator housing into an operator chain compartment, which is open to the exterior, and a drive compartment, which is substantially sealed from the exterior, wherein the barrier member is a separate member that is insertable into said chain operator housing.

2. A chain operator housing according to claim 1, wherein the barrier member comprises a bearing surface against which an operator chain may slide.

3. A chain operator housing according to claim 1, wherein the barrier member is an injection molded plastic member.

4. A chain operator housing according to claim 1, wherein the barrier member comprises positioning means for positioning the barrier member with respect to said operator housing, said positioning means cooperating with said operator housing.

5. A chain operator housing according to claim 1, wherein said operator housing comprises means for attaching a chain magazine to said operator housing.

6. A chain operator housing according to claim 1, further comprising a substantially planar bottom wall and a protrusion extending externally from said bottom wall.

28. A chain operator housing according to claim 2, wherein the barrier member is an injection molded plastic member.

7. A chain operator for windows, comprising:

an operator chain;

an operator housing comprising an exit opening for said operator chain;

a sprocket for driving said operator chain in and out of said exit opening; and

at least one gear wheel in fixed coaxial connection with said sprocket, wherein a barrier member is arranged within said operator housing, said barrier member comprising a barrier arranged between said exit opening and at least most of said gear wheel.

8. A chain operator according to claim 7, wherein the barrier member is a separate member that is insertable into said chain operator housing.

9. A chain operator according to claim 7, wherein the barrier member further comprises a bearing surface against which the operator chain may slide.

10. A chain operator according to claim 7, wherein the barrier member is an injection molded plastic member.

11. A chain operator according to claim 7, wherein the barrier member further comprises positioning means for positioning the barrier member with respect to said operator housing, said positioning means cooperating with said operator housing.

29. A chain operator according to claim 7, further comprising a stop member for the operator chain, wherein the operator chain has a width, rivet holes and rivets, and the stop member comprises a pin arranged in a rivet hole not occupied by a rivet in the operator chain, said pin having a length exceeding the width of the operator chain.

12. A chain operator for windows, comprising

an operator chain;

an operator housing comprising an entry opening for said operator chain and an exit opening for said operator chain and

a sprocket for driving said operator chain into and out of said exit opening, wherein said operator housing further comprises attachment means for attaching a chain magazine to said operator housing and in communication with said entry opening.

13. A chain operator according to claim 12, wherein said attachment means comprises profiled rails on said operator housing.

14. A chain operator according to claim 13, wherein said profiled rails comprise a cross section selected among the group of substantially T shaped, substantially L shaped, keyhole shaped and dovetail profiles.

15. A chain operator according to claim 14, wherein said attachment means further comprises an undercut groove.

16. A chain operator according to claim 15, wherein said undercut groove comprises a cross section selected among the group of substantially T shaped, substantially L shaped, and dovetail cross sections.

30. A chain operator according to claim 12, further comprising a chain magazine having a housing and attachment means for releasably attaching the chain magazine to the operator housing without the use of tools.

17. A chain operator housing (1) comprising a substantially planar bottom wall and a protrusion extending externally from said bottom wall.

23. A chain operator housing according to claim 17, further comprising a cylindrical wall portion extending internally from said bottom wall, said cylindrical wall portion defining a bore for holding a spindle on which a sprocket and gearwheel assembly is mounted.

24. A chain operator housing according to claim 23, wherein said bore extends at least partially through the substantially planar bottom wall in a direction towards the external protrusion.

25. A chain operator housing according to claim 24, wherein said bore extends through the substantially planar wall into the external protrusion.

26. A chain operator housing according to claim 17, wherein said protrusion is cylindrical.

27. A chain operator housing according to claim 23, wherein the end surface of the cylindrical wall portion forms a bearing surface for the sprocket and gearwheel assembly.

18. A chain operator housing comprising.

an entry opening for an operator chain;

an exit opening for the operator chain; and

attachment means for attaching a chain magazine to said operator housing and in communication with said entry opening.

19. A chain magazine comprising

a housing;

and

attachment means for releasably attaching the chain magazine to a chain operator without the use of tools.

20. A stop member for an operator chain in a chain operator, wherein the operator chain has a width, rivet holes and rivets, comprising a pin arranged in a rivet hole not occupied by a rivet in the operator chain, said pin having a length exceeding the width of the operator chain.

21. A stop member according to claim 20, wherein the pin is cylindrical with a diameter corresponding essentially to that of the rivet hole.

22. A stop member according to claim 21, wherein said the diameter of the pin is slightly smaller than that of the rivet hole, so as to be loosely held in said rivet hole.
