Description
SPECIFICATION
A device for clamping to a sheet of flexible material
This invention relates to a device which can be fixed to a sheet or piece of flexible material to enable a member to be connected to the sheet or piece. Such flexible material may comprise a sail cloth, parachute material, tent material, webbing, tarpaulins, etc.
The device may comprise a sail clew. A sail clew is a member having an eyelet provided on the bottom corner of a sail remote from the mast and used for adjusting the tension of the bottom edge of the sail so that the bottom edge of the sail is either held taught or allowed to bow.
According to the present invention there is provided a device which can be fixed to a sheet or piece of flexible material to enable a member to be connected to the sheet or piece, comprising an outer member having a portion provided with a transverse hole or holes or a recess for receiving the members to be connected to the sheet or piece, a pair of opposed limb portions extending from one end of said portion, an inner clamping member received between said limb portions, said inner clamping member comprising a first portion or member disposed on the inner side of one limb portion and a second portion or member disposed on the inner side of the other limb portion and arranged to receive the sheet or piece of material therebetween, at least one of said portions or members being provided with teeth which penetrate through the material and into the other of said portions or members when the opposed limb portions are forced towards each other to cause the portions or members of the inner clamping member to clamp the sheet or piece of material.
Some embodiments of the invention will now be described, by way of examples, with reference to the accompanying drawings, in which Figure 1 is a side elevation of a device according to the present invention and constituting a sail clew,
Figure 2 is a transverse section taken along the line 2-2 of Fig. 1,
Figure 3 is a transverse section through the outer member of the device before assembly,
Figure 4 is a transverse section through the inner member before assembly,
Figure 5 is a side elevation of the toothed strip,
Figure 6 is a side elevation of a device according to the present invention for fixing a slider to a sail, and
Figure 7 is a section taken along the line 7-7 of Fig. 6.
The device 10, which is in the form of a sail clew, comprises an outer member 11 which is formed of any suitable material which can be extruded, such as an aluminium alloy or stainless steel alloy. The outer member 11 comprises a portion 1 2 which is provided with one or more holes 1 3 depending upon its length. Extending from one edge of the portion 1 2 are two opposed limb portions 1 4 provided at their outer ends with an inwardly directed flange 1 5. The outer member 11 is formed from an extruded strip which is cut to the required length and the limb portions of the strip diverge away from the portion 1 2.
Provided between the limb portions 1 4 is an inner clamping member 1 6 which is pre feebly formed of extruded material of the type sold under the registered Trade Mark "Nylon". The clamping member 1 6 comprises two portions 1 7 and 1 8 which are joined together by a web portion 19, the portion 1 7 being provided with a channel 20 in which is received a metal strip 21 preferably formed of stainless steel having along an outer edge a plurality of teeth 22.
In order to assemble and fix the device 10 to a sail 23 the strip 21 is inserted in the channel 20 of the member 1 6 with the teeth 22 directed away from the channel 20 and the strip 21 is bent about the web portion 1 9 and inserted between the limb portions 1 4 of the outer member 11. The assembly is the placed onto the sail 23 with the sail 23 received between the portions 1 7 and 1 8 and the limb portions 1 4 are pressed towards each other to the position shown in Fig. 2 so that the portions 1 7 and 1 8 clamp the sail 23 therebetween and the teeth 22 penetrate through the sail 23 and into the portion 1 8.
The flanges 1 5 engage one end of the portions 17 and 18.
It will be appreciated that each of the portions 1 7 and 1 8 can be provided with a toothed strip 21 and that each can be provided with more than one toothed strip.
It will also be appreciated that the portions 1 7 and 1 8 can be separate from each other instead of being joined together by web portion 19.
When the limb portions 1 4 have been pressed together they preferably converge towards each other in a direction towards their outer edges. The resultant fastening to the sail 23 is secure and due to the length of the clew 10 the region of the sail to which the clew 10 is fastened does not distort when a pulling force is applied to the clew 10 to tension the bottom of the sail 23.
Alternatively, the inner clamping member 1 6 may be formed of a soft metal, such as copper.
When the portions 1 7 and 1 8 are separate pieces, each may be received in a suitably shaped recess provided in the inner face of each limb portion 1 4. Such recesses may be of dovetail configuration.
The device 10 may be used with sail cloth, parachute material, tent material, webbing or tarpaulins etc, and enables a member such as a rope to be connected to the material.
As shown in Figs. 6 and 7 the device 10 can be used for fixing a slider 24 to a sail, the slider 24 having a portion 25 which is received in a circular recess 26 provided in the portion 1 2 of member 11. The portion 25 can be provided with a shackle hole 27 or alternatively the hole 27 can be provided in the member 10. In this embodiment the portion 1 2 of the member 11 is not provided with a transverse hole or holes.
Claims (8)
1. A device which can be fixed to a sheet or piece of flexible material to enable a member to be connected to the sheet or piece, comprising an outer member having an end portion provided with a transverse hole or holes or with a recess for receiving the member to be connected to the sheet or piece, a pair of opposed limb portions extending from said end portion, an inner clamping member received between said limb portions, said inner clamping member comprising a first portion or member disposed on the inner side of one limb portion and a second portion or member disposed on the inner side of the other limb portion and arranged to receive the sheet or piece of material therebetween, at least one of said portions or members of the clamping member being provided with teeth which penetrate through the flexible material and into the other of said portions or members of the clamping member when the opposed limb portions are forced towards each other to cause the portions or members of the inner clamping member to clamp the sheet or piece of material therebetween.
2. A device as disclosed in claim 1, in which the inner clamping member comprises two portions joined together by a web portion.
3. A device as claimed in claim 1, in which the inner clamping member comprises two separate portions each received in a recess provided on the inner face of each limb portion.
