Description

(54) IMPROVEMENTS IN FENCING (71) We, DENECROWN LIMITED, a British Company, of 38 East Bank Road, Sheffield, S2 3PS, South Yorkshire, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to fencing.

Known types of fencing are generally made of rigid materials, such as wood or metal, and are both expensive and susceptible to damage on impact.

The present invention seeks therefore to provide inexpensive fencing which is suitable for use along a road or motor way or even to surround stock and which will absorb energy on impact rather than becoming deformed.

According to the present invention, there is provided fencing comprising a plurality of posts supporting at intervals along its length a band of flexible material which comprises a non-metallic textile material core impregnated and/or coated with a natural or synthetic resilient polymer.

The core of textile material may be woven, formed from separate plies of woven material laminated together or from an integrally woven multiple ply textile fabric, for example. Alternatively, the core may be made up of multiple- or single-filament yarns assembled or entwined together.

It is desirable that the core of textile material should be synthetic so as to be water resistant. The core may be made from continuous filament yarns, such as polyamides and polyesters or more specifically, polyester polyamide, or staple fibre yarns for this purpose.

The resilient polymer which is used to impregnate and/or coat the textile material core is preferably an elastomer. Possible elastomers are polypropylene acrylics, polyurethane, polyvinyl chloride, rubber, blends of polyvinyl chloride and rubber, or thermoplastic synthetic polyester.

The parallel posts are conveniently rigid and of any desired cross section, made, for example, from wood, metal, or an extruded or moulded elastomer, e.g. moulded self skinning urethane foam, which may be reinforced, and are provided with suitable attachment means by which the band of flexible material is supported. For example, the band may fit through slots in the posts or be received in eyelets mounted on the posts.

Alternatively it may simply be nailed to the posts. Further bands of flexible material may also be supported by the posts if desired.

The invention will be described further, by way of example, with reference to the drawings accompanying the provisional specification, in which: Fig. 1 is a cross-section through one form of band used in the fencing; Fig. 2 is a cross-section through a second form of band; Fig. 3 is a view of one embodiment of a fence; Fig. 4 is a view of a modified means for securing the bands to the posts in the fence of Fig. 3; Fig. 5 is a view of a second type of post; Fig. 6 is a view of a fence incorporating the posts of Fig. 5, and Fig. 7 is a view of tensioning means for tensioning the bands in the fence of Fig. 6.

Fig. 1 is a cross section through the weft of a band which is formed from an integrally woven multiple ply textile fabric. In this instance the band is a three ply fabric having three superimposed plies 10, 12, 14. The ply 10 comprises weft yarns 10a woven together by warp yarns 10b, 10c, the warp yarn lOb passing over the first, under the second and over the third weft yarn 10a (viewed in the warp direction), and so on, and the warp yarn 10c weaving under and over the weft yarns 10a in opposition to the yarn 10b. Likewise, the plies 12, 14 have, respectively, weft yarns 12a, 14a and warp yarns 12b, 12c, 14b, 14c.

The upper and middle plies are interlocked by two further warp yarns 16, 18. The warp yarn 16 is taken over the second and every next but three weft yarns 10a while passing under the fourth and every next but three weft yarn 12a. In each weft position that the yarn 16 passes over a weft yarn 10a the warp yarn 18 passes under a weft yarn 12a and in the weft positions where the yarn 16 weaves under a weft yarn 12a, the yarn 18 weaves over a weft yarn 10a.

In a similar fashion, the middle and lower plies are bound together by two warp yarns 20, 22.

All the weft and warp yarns are synthetic and the woven core shown in Fig. 1 is impregnated and also has a surface coating of polyvinyl chloride.

Shown in Fig. 2 is a band having a rope like structure made up of a plurality of nylon or polyester monofilament yarns 30 which are coated with a layer 32 of polyvinyl chloride, polypropylene or polyurethane.

The fence shown in Fig. 3 is made up of four bands 40 of either the type shown in Fig.

1 or the type shown in Fig. 2 and a number of rigid upright posts 42. The bands 40 are secured to the posts by nails, screws, rivets or other like means 44 and the posts are, in use, embedded in the ground.

Alternatively the bands 40 may be received in eyelets 46, one of which is shown in Fig. 4. The eyelet 46 has a back 48 bolted to the post 42 and two limbs 50, 52 projecting at right angles to the back 48. These limbs are provided with flanges 54, 56 respectively for retaining the bands. The eyelets might, alternatively, be O-shaped.

A further embodiment of the fence is illustrated in Figs. 5 to 7. In this embodiment, T-shaped posts 60 support the bands 40. The posts rest on the bar part 62 of the T and their stems 64 have slots 66 through which the bands 40 pass. Tensioning means 70, shown in Fig. 7, may be used with this type of fencing.

It will be appreciated that an integrally woven multiple ply textile band other than that shown in Fig. 1 may be used or even a simple ply textile band.

In addition, pigmentation may be added to the material used to impregnate and/or coat the band. Likewise substances can be added to this material to give a fluorescent or reflective finish, if desired.

The fencing described may be used to enclose stock on agricultural land or along a road-side and may be produced cheaply using continuous methods of construction.

WHAT WE CLAIM IS: 1. Fencing comprising a plurality of posts supporting at intervals along its length a band of flexible material which comprises a nonmetallic textile material core impregnated and/or coated with a natural or synthetic resilient polymer.

2. Fencing as claimed in claim 1 wherein the core is formed from separate plies of woven material laminated together.

The warp yarn 16 is taken over the second and every next but three weft yarns 10a while passing under the fourth and every next but three weft yarn 12a. In each weft position that the yarn 16 passes over a weft yarn 10a the warp yarn 18 passes under a weft yarn 12a and in the weft positions where the yarn 16 weaves under a weft yarn 12a, the yarn 18 weaves over a weft yarn 10a. In a similar fashion, the middle and lower plies are bound together by two warp yarns 20, 22. All the weft and warp yarns are synthetic and the woven core shown in Fig. 1 is impregnated and also has a surface coating of polyvinyl chloride. Shown in Fig. 2 is a band having a rope like structure made up of a plurality of nylon or polyester monofilament yarns 30 which are coated with a layer 32 of polyvinyl chloride, polypropylene or polyurethane. The fence shown in Fig. 3 is made up of four bands 40 of either the type shown in Fig.

1 or the type shown in Fig. 2 and a number of rigid upright posts 42. The bands 40 are secured to the posts by nails, screws, rivets or other like means 44 and the posts are, in use, embedded in the ground.

Alternatively the bands 40 may be received in eyelets 46, one of which is shown in Fig. 4. The eyelet 46 has a back 48 bolted to the post 42 and two limbs 50, 52 projecting at right angles to the back 48. These limbs are provided with flanges 54, 56 respectively for retaining the bands. The eyelets might, alternatively, be O-shaped.

A further embodiment of the fence is illustrated in Figs. 5 to 7. In this embodiment, T-shaped posts 60 support the bands 40. The posts rest on the bar part 62 of the T and their stems 64 have slots 66 through which the bands 40 pass. Tensioning means 70, shown in Fig. 7, may be used with this type of fencing.

It will be appreciated that an integrally woven multiple ply textile band other than that shown in Fig. 1 may be used or even a simple ply textile band.

In addition, pigmentation may be added to the material used to impregnate and/or coat the band. Likewise substances can be added to this material to give a fluorescent or reflective finish, if desired.

The fencing described may be used to enclose stock on agricultural land or along a road-side and may be produced cheaply using continuous methods of construction.
