Description

IMPROVEMENTS IN OR RELATING TO HAND RAILS
The present invention relates generally to hand rails and particularly to aspects of safety, production and assembly of, and connections of, hand rails.
Hand rail structures are used in a wide range of circumstances and for a variety of reasons. For example, hand rail structures may be deployed along staircases or walkways to serve as a support for people as they move. Alternatively or additionally hand rail systems can be used as barriers or fences" to delimit an area.
There are a variety of considerations when designing a hand rail system, primarily safety aspects but also material choice, production techniques and ease of assembly which will influence the properties and performance of the resulting structure that is in turn dictated by, for example, the final application (such as offshore installations).
The present invention seeks to provide improvements in or relating to hand rail systems.
According to a first aspect of the present invention there is provided a handrail connector comprising a top rail connection part attachable to one or more top rail sections and a post connection part attached or attachable to a support post, in which the post connection part is articulated with respect to the rail connection part.
This means that, in use, the top rail and/or support post can be inclined to accommodate different underlying surfaces/slopes.
The connector may comprise a main body part which both forms part of the top rail and receives a support post in use.
The top rail connection part may comprise a projection or recess for engaging a corresponding recess or projection on a rail section.
The rail connection part may be adapted to be flush fitting with a rail section.
The post connection part may comprise a socket for receiving part of a post internally.
The post connection part may be formed separately from the rail connection part.
The post connection part may form a joint with the rail connection part. The joint between the rail connection part and the post connection part may be made inside the rail connection part.
The post connection part may form a hinging joint with a, or for a, support post. This means that, in use, the top rail and/or support post can be inclined to accommodate different surfaces.
The post connector may include a post adapter received in the connector and being connectable to a support post. The post adapter may be hingedly received.
The connector may be adapted to form an integral part of the top rail structure. In some embodiments part of the connector effectively forms an intermediate top rail section so that the top rail is not interrupted by the connector.
The post connection part may be connected to the rail connection part by a hinge pin. The hinge pin permits articulation of the post and rail with respect to each other.
The connector may be generally f-shape.
The post and rail connector parts may be formed integrally with a post/rail, or may be formed separately and with some means of a stable connection to a post/rail.
The material from which the hand rail system is produced is an important consideration.
The material from which all of the components of the hand rail system may be the same or, depending on the circumstances may be different.
The synthetic material may comprise a composite material such as an advanced composite. For example, the material may comprise a reinforced composite material such as a fibre-reinforced plastic (FRP) material, which is a composite material of fibre glass (or other fibre) in a polymer matrix. FRP is seen as a particularly suitable material from which to form the hand rail structures of the present invention. FRP combines low weight with high strength and provides corrosion resistance and excellent thermal and electrical insulation. Because FRP materials have low thermal conductivity they can have particular benefits when used in cold weather conditions, where they are "warm' to the touch. Other advantageous properties may include low electrical conductivity and electromagnetic transparency.
The FRP material can be selected on the basis of required properties for the resulting hand rail systems, for example polyester-, epoxy-, and vinyl ester-based materials. For example phenolic-based FRP materials can be used. Other suitable component materials may include bioresins and natural fibres to form a reinforced composite material.
Phenolic-based FRP materials have presented significant difficulties in production, for example, by pultrusion. However, the inventors have surprisingly found that phenolic- FRP can be used to form hand rail structures which have particularly good fire-resistance properties. Phenolic-based FRP hand rails may have particular benefits for off shore applications, such as oil rigs.
The material may be provided in various forms for production (for example by moulding) such as sheet moulding compound (SMC) or dough moulding compound (DMC).
According to a second aspect of the present invention there is provided a handrail system comprising one or more top rail sections, one or more support posts and one or more connectors as described herein.
The present invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a hand rail arrangement including a connector formed according to an aspect of the present invention; Figure 2 is a side view of the arrangement of Figure 1; Figure 3A is a side view of the connector of Figures 1 and 2 shown in a first position: Figure 3B is a side elevation of the connector of Figure 3 shown in a second position; Figure 4 is a an underside perspective view of the connector of Figures 3A and 3B; Figure 5 is a section of the connection of Figure 3A taken along line A-A; Figure 6 is a perspective view of a rail connection part of the connector of Figures 3 to 5; Figure 7 is an alternative perspective view of the part of Figure 6; Figure 8 is an end elevation of the part of Figure 6; Figure 9 is a side elevation of the part of Figure 6; Figure 10 is a plan view of the part of Figure 6; Figure 1 1 is an underplan view of the part of Figure 6; Figure 12 is perspective view of a post connection part of the connector of Figures 3 to 5; Figure 13 is a plan view of the part of Figure 12; Figure 14 is an underplan view of the part of Figure 12; Figure 15 is a front elevation of the part of Figure 12; and Figure 16 is a side elevation of the part of Figure 12.
Referring first to Figures 1 and 2 there is shown a hand rail assembly generally indicated 10. The assembly 10 comprises a rectilinear top rail 15 and a plurality (in this case three are shown) of depending support posts 20. At one end of the rail 15 a support leg 25 is connected orthogonally by an articulating connector 30. A cross member 35 extends parallel to the top rail 15 from the leg 25 through the posts 20; in some embodiments the cross member 25 may comprise a plurality of sections extending between adjacent posts and between the leg 25 and the adjacent post 20.
The top rail 15 is of generally cylindrical shape with a circular cross section. The rail 15 is made up of a number of rail sections 40 which are joined by connectors 45 which also receive the post 20 as described in more detail below. Each post 20 is received on the underside of the connector 45 and the connectors 45 are the same diameter as the sections 40. This means that the connector 45 provides a surface which can itself be gripped by a user and the interface between the connector 45 and the adjacent rail sections 40 is such that a user does not need to remove their hand to pass over the intersections. Accordingly, the rail 15 presents a substantially continuous gripping surface along its length.
Referring now to Figures 3 to 14 the post-to-rail joint connector 45 is shown in more detail.
The connector 45 is generally T-shape and comprises a generally cylindrical rail connector part 46 and an elongate post connector part 70.
The rail connector part 46 comprises a central body 50 having at either end a cylindrical dowel portion 55, 56. The dowel portions 55, 56 are dimensioned to fit tightly within the ends of rail sections 40 and each dowel 55, 56 is provided with circumferential ribs 60 on their outer surfaces to centralise the fit to ensure a consistent adhesive line thickness.
The central section 50 includes a socket 65 having a generally rectangular cross section. The socket 65 is offset from the centre of the section 50 towards the dowel 55.
The socket 65 receives the post connector part 70.
The post connector part 70 comprises an articulation leg 75 received in the socket 65 and having a semi-circular end 76 with a fixing hole 77. The leg 75 extends to a post cap 80 from which depends a fixing section 85. The fixing section 85 has a generally square cross section and is provided on its externat surface with a plurality of longitudinal ribs 90. The section 85 is received in the top of a post 20 and pushed in until the cap 80 abuts against the end of the post 20 in a flush fit.
In use the rail sections 40 are pushed onto the dowels 55, 56 until they abut against the central section 50. The central section 50 has the same cross section and diameter as the rail sections 40 so that there is a flush fit at the intersections.
The central section 50 is provided with a pin hole 95 and the leg 75 is also provided with a pin hole 77. The holes 95, 77 are aligned and a hinge pin 105 is passed through to join the leg 75 to the body 50 in a hinging joint.
This means that the joint between the body 50 and the leg 75 is articulated so that in use the angle between posts (via post connectors) and the hand rail can be varied as illustrated by Figures 3A and 3B to accommodate different situations.
