Abstract

In order to provide varied grip characteristics, a rail member (1) of a grab-rail has an outer surface with a plurality of longitudinally extending ribs (4) positioned to provide a rough zone which is adjacent to a smooth zone. Preferably, the cross-section of the rail member is elliptical so that the rail member may be mounted in a non-rotatable manner.

Description

The present invention relates to a grab-rail which is, for example, positionable by a bath to assist a user of the bath to get into and out of the bath.
According to the present invention, there is provided a grab-rail comprising an elongate rail member having an outer surface with a plurality of longitudinally extending ribs positioned to provide a rough, first zone which is adjacent to a smoother, second zone. By means of the first and second zones, it is possible to provide enhanced grip where it is needed, by means of the first zone, and a cleaner visual appearance where grip is not needed, by means of the second zone.
Preferably, the cross-section of the rail member is non-circular. If the cross-section is oval, e.g. elliptical, it is preferable that the first and second zones are disposed on respective sides of the major axis of the cross-section of the rail member.
The grab-rail may be a folding grab-rail, wherein a base portion is securable to a support surface and the rail member is pivotably connected to the base portion so as to be movable between a first, generally horizontal position and a second, generally vertical position. It is preferable that the rail member is arranged so that, when in its first position, the rough, first zone faces downwards and the smoother, second zone faces upwards. With this arrangement, when the user grabs hold of the rail member, e.g. in order to get out of a bath, the user's fingers achieve a good grip on the underside of the rail member whilst ensuring that the top side of the rail member does not cause any discomfort to the palms of the user's hands.
The grab-rail may be a fixed grab-rail wherein a bracket is fixed to each end of the rail member and is securable to a support surface. Preferably, the rail member is arranged so that the rough, first zone faces towards the support surface and the smoother, second zone faces away from the support surface.
Two non-limiting embodiments of the present invention will now be described with reference to the accompanying drawings, in which:

Figure 1 is a perspective view of a fixed grab-rail;
Figure 2 is a cross-section of the rail member of the fixed grab-rail of Figure 1; and
Figure 3 is a perspective view of a folding grab-rail.

Referring to Figures 1 and 2, the fixed grab-rail comprises a rail member 1 to the ends of which are fixed brackets 2 having screw holes 3 by means of which the fixed grab-rail may be fixed to a wall or the like.
The rail member 1 has an elliptical cross-section, on one side of the major axis of which are disposed a plurality of parallel ribs 4 and on the other side of the major axis of which the outer surface of the rail member is smooth. The ribs 4 extend parallel to the longitudinal axis of the rail member 1 and form a rough, first zone of the outer surface of the rail member 1. The rest of the outer surface forms a smooth, second zone. The rail member 1 is arranged so that the ribs 4 face towards the wall on which the grab-rail is mounted. Thus, the ribs 4 are only just visible in Figure 1.
Because, as viewed in Figure 2, the right-hand side of the outer surface of the rail member 1 is rib-free, a user pressing his or her palms against the rail member 1 will feel no discomfort. However, the fingers wrapped around the rail member 1 will come into contact with the ribs 4 and thereby enable the user to obtain a good grip on the rail member. Having the ribs 4 cover only half of the outer surface of the rail member 1 has been found to be the most effective arrangement.
As may be seen from Figure 2, the rail member 1 is hollow. Each bracket 2 has a boss which is not visible in Figure 1 and which projects into the hollow interior of the rail member 1. The boss has an elliptical cross-section which conforms to the inner surface of the rail member 1. In this way, the rail member 1 is prevented from rotating. The rail member 1 and brackets 2 are made from polycarbonate material and are joined together by means of adhesive or, less preferably, ultrasonic welding. The rail member 1 is produced by extrusion, and the brackets 2 are produced by moulding.
The folding grab-rail shown in Figure 3 has a base portion 5 of conventional design which is securable to a wall. A generally U-shaped rail assembly 6 is pivotably mounted in the base portion 5 so as to be pivotable between the horizontal position shown in Figure 3 and a vertical position used for storage. The rail assembly 6 comprises a rail member 1 of identical design to that shown in Figures 1 and 2. The rail member 1 is supported by other rails 7 of circular cross-section. The rail member 1 is arranged so that its ribs 4, which are not visible in Figure 3, face downwards when the rail assembly 6 is in the horizontal position shown in Figure 3. Thus, the user's palms may be used to support the user's weight on the smooth zone of the rail member 1, whilst the user's fingers grip the ribs 4 on the underside of the rail member 1.
Instead of being U-shaped, the rail assembly may be straight and comprise the rail member 1.

Claims
