Telescopic Hand Rail

Abstract

A telescopic handrail (1) with telescoping members (10,20) that can move between contracted and expanded positions. The telescoping members (10,20) each have a free end (11,21) and an opposing telesco

Description

A locking means is provided to releasably secure the telescoping members in the first contracted position. The locking means is in the form of a magnet 23 on an end cap 24 at the telescoping end 22 of tube 20, and a metal plate 13 attracted to magnet 23 on a first fixing device 30 at the free end 11 of tube 10. The magnet and plate releasably hold the first and second telescoping members in the first contracted position, but the force of the magnet can be overridden by manually pulling the second tube 20 out of the first tube 10. A sleeve 14 in the end 12 of tube 10 provides a bearing surface between the tubes 10,20. Restraining means is provided to prevent the telescoping members from separating more than the second expanded position. The restraining means is in the form of a shaft 40 (or wire) fixed at one end to first fixing device 30 at the free end 11 of tube 10. Shaft 40 slides through an aperture 24A in the end cap 24 of tube 20, and shaft 40 has a stop 41 to prevent the aperture 24A in end cap 24 sliding off the end of the shaft 40 and limiting withdrawal of the second tube from the first tube to define the second contracted position. The telescoping members can freely slide without restrain relative to each other between the first and second positions. First fixing device 30 has a wall pate 31, with wall fixings 31 A, connected to a tube cap 32 by means of a universal joint 33. First fixing device 30 can be used to secure a free end 11 of tube 10 to a fixed point, such as the wall at the top of some stairs (see Figure 3 described below). The first fixing device joint 33 allows movement of the telescoping members in two planes relative to the first fixing device wall plare 31. A second releasable fixing device 50 is provided to releasably secure a free end 21 of the tube 20 to a fixed point, such as a wall opposing a staircase (see Figure 3 again). Fixing device 50 has a wall plate 51, with wall fixings 51A and a projection 52 with a pin aperture 53. Device 50 has a separate tube cap 55 with a projection 56 carrying a pin 57, Pin 57 can be inserted in aperture 53 to secure the wall plate 51 to tube cap 55 and so secure the free end 21 of tube 20 to a wall or other fixed point. As an alternative, a separate pin could be passed through an aperture in the wall plate and tube cap to lock the wall plate and tube cap together. Referring to Figure 3, there is shown a landing Y at the top of stairs X with bannister Z, and a door D opposite the top of the stairs. When not in use, handrail 10 is secured by first fixing device 30 to the wall adjacent the top of stairs X. Handrail 10 is stored in the first contacted position and dangles vertically downwards off the wall plate 31. In this positon it does not interfere physically or visually with normal use of the stairs and landing. When in use, the handrail can be extended to the second expanded position and the pin 57 can be inserted into aperture 53 on wall plate 51 mounted on an opposing wall adjacent door D. In this position handrail can be used by a person going up the stairs and needing a handrail from the stairs X to the door D. The handrail of the invention can be used in many locations as required in a building. One or more telescoping members could have glow in the dark paint or fluorescent paint or sticker / s. Also glow in the dark paint or fluorescent paint or sticker / s could be placed adjacent the aperture 53 to help locate pin 57 into the aperture 53 when it is dark. The invention may take a form different to that specifically described above. Further modifications will be apparent to those skilled in the art without departing form the scope of the present invention.

Claims

1. A telescopic handrail comprising:a) first and second telescoping members adapted to move from a first contracted positon to a second expanded position, said telescoping members each having a free end and an opposing telescoping end,b) locking means to releasably secure the telescoping members in the first contracted position, c) restraining means to prevent the telescoping members from separating more than the second expanded position,d) a first fixing device to secure a free end of the first telescoping member to a fixed point, and e) a second releasable fixing device to releasably secure a free end of the second telescoping member to a fixed point.

2. A telescopic handrail according to claim 1, wherein the telescoping members can freely slide without restrain relative to each other between the first and second positions.

3. A telescopic handrail according to claim 1 or 2, wherein the first fixing device allows movement of the telescoping members in two planes relative to the first fixing device.

4. A telescopic handrail according to claim 3, wherein the first fixing device is connected to first telescoping member through a universal joint.

5. A telescopic handrail according to any preceding claim, wherein the second fixing device has a remote member to secure to a structure and an engagement member on the free end of second telescoping member to releasably engage with the remote member.

6. A telescopic handrail according to claim 5, wherein the remote member has an aperture to releasably receive a pin on the engagement member.

7. A telescopic handrail according to any preceding claim, wherein the locking means includes a magnet to releasably hold the first and second telescoping members in the first contracted position.

8. A telescopic handrail according to any preceding claim, wherein the restraining means is a shaft fixed at one end to the free end of one telescoping member and which shaft slides through an aperture in the telescoping end of the other telescoping member, said shaft at its other end having a stop to prevent the aperture in the telescoping end of the other telescoping member sliding off the end of the shaft.
