Abstract
Abstract A device for connecting pavers (11, 12) together to form roads comprises a base plate (17) from which extend tubular projections (18). The tubular projections can extend into bores (13, 14) formed in the pavers and a fastener (20) is provided which can lock the paver to a respective projection. Typically, the device has four projections to allow four pavers to be locked together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A device for fastening together a plurality of elements in which each element has an upper surface and a lower surface and a bore extending therebetween, the device comprising a base plate adapted to be located against a ground surface and to be positioned below and against at least part of the lower surface of each element, a plurality of projections extending from the base plate, one said projection being adapted to pass at least partially into the bore of one said element, and another said projection being adapted to pass at least partially into the bore of another element, and a plurality of fasteners, each fastener being engageable with a respective projection to fasten a said element to the device, wherein each projection is hollow, includes an open top and comprises a plurality of outwardly deformable fingers and each fastener comprises a plug which can be pressed between the fingers to cause the fingers to deform outwardly to grip walls of the bore of the element thereby securing the element to the device.
Claim 2
Independent Claim
174 words
A device for fastening together a plurality of elements in which each element has an upper surface and a lower surface and a bore extending therebetween, the device comprising a base plate adapted to be located against a ground surface and to be positioned below and against at least part of the lower surface of each element, a plurality of projections extending from the base plate, one said projection being adapted to pass at least partially into the bore of one said element, and another said projection being adapted to pass at least partially into the bore of another element, and a plurality of fasteners, each fastener being engageable with a respective projection to fasten a said element to the device, wherein each projection is hollow, includes an open top and comprises a plurality of outwardly deformable fingers and each fastener comprises a plug which can be pressed between the fingers to cause the fingers to deform outwardly to grip walls of the bore of the element thereby securing the element to the device.
Claim 3
Dependent Claim
49 words
The device of claim 1, wherein the fingers are substantially planar and have horizontal ribs extending across inner walls of the fingers, and the plug has a body provided with external ribs which can engage with the ribs on the fingers when the plug is pressed between the fingers.
Claim 4
Dependent Claim
48 words
The device of claim 2, wherein the base plate is rectangular when viewed in plan and a said projection is positioned adjacent each corner of the base plate and extends substantially at right angles therefrom and each projection is tapered from a wider base to a narrower top.
Claim 5
Dependent Claim
16 words
A paving system comprising a plurality of pavers interconnected by devices as claimed in claim 1.
Claim 6
Dependent Claim
12 words
The paving system of claim 4, wherein the pavers comprise road pavers.
