Guide for stairlift
The invention relates to a guide for a lift along a staircase, comprising an elongate profile with at least one edge thereon, which edge extends along a considerable part of the length of the profile, wherein the edge of the profile is serrated and forms a gear rack for engagement thereon by a drive of the lift.
1. Guide for a lift along a staircase, comprising:
an elongate profile having a pair of opposed major surfaces and a side surface that extends between the opposed major surfaces,
wherein the side surface of the profile is serrated to form a gear rack that extends from the side surface,
wherein the gear rack is engageable with a drive of the lift, and
wherein the profile and the gear rack are of a unitary, one-piece construction.
2. Guide as claimed in claim 1 , wherein the profile is formed from elongate flat plate material that is bent.
3. Guide as claimed in claim 2 , wherein the plate material is bent after the side surface has been serrated.
4. Guide as claimed in claim 2 , wherein the profile is formed from the plate material with roller-forming.
5. Guide as claimed in claim 1 , wherein the serrated side surface is punched on the side surface of the profile.
6. Guide as claimed in claim 1 , wherein during use of the guide the side surface is oriented parallel to a wall of a stairwell in which the guide is then placed, with the gear rack out of sight and beyond harmful and obstructing reach.
7. Guide as claimed in claim 1 , wherein the gear rack is formed in accordance with a standard norm.
8. Guide as claimed in claim 1 , wherein the gear rack comprises an evolvent toothing.
9. Guide as claimed in claim 1 , further comprising an additional profile.
10. Guide as claimed in claim 9 , wherein the additional profile comprises a flange which extends at a distance along the gear rack.
11. Guide as claimed in claim 9 , wherein the additional profile is open with an opening therein.
12. Guide as claimed in claim 11 , wherein the opening and the form of the additional profile are designed for engaging therethrough and receiving therein of a support wheel of the lift.
13. Guide as claimed in claim 1 , which defines a path comprising at least one curve for the lift.
14. Guide as claimed in claim 1 , wherein the profile with the serrated side surface is open along a considerable part of the length thereof and the serrated side surface extends along the opening.
15. Guide as claimed in claim 14 , wherein the opening and the form of the profile are designed for engaging therethrough and receiving therein of a support wheel of the lift.
16. System comprising a guide as claimed in claim 1 , and a lift along a staircase.
17. Guide as claimed in claim 3 , wherein the profile is formed from the plate material with roller-forming.
18. Guide as claimed in claim 10 , wherein the additional profile is open with an opening therein.
