Description
SPECIFICATION
Fastener for sheet materials
Field of the invention
This invention relates to means of fastening together edges of resiliently flexible sheet materials such as sheet metal, polyvinyl chloride and polyethylene. Such sheet materials are typically used as protective casings for pipes and conduits.
Such casings are usually fitted around insulating material which itself surrounds a pipe or conduit, and they serve to prevent abrasion of or other damage to the insulating material by contact with external agents and also to prevent ingress of water and other harmful fluids. In cases where the insulating material is a powder or other friable solid or a fluid, such casings may be fitted around a pipe or conduit before a space between the pipe or conduit and the casing is filled with insulating material in place as well as to protect it from damage.
Prior art
Casings of the kind described are usually made of sheet metal or of resilient sheet plastics materials such as polyvinyl chloride. Because installations differ it is rarely practicable to use standardized prefabricated sleeves, and the usual practice is to make the casings from sheets of the casing material by cutting them to size and pre-rolling them, then wrapping them around the pipes and joining the edges by welding rivetting or adhesives. Such joins preventthe casings from being removed and reused after, for example, replacement of insulating material, and they rarely provide permanent sealing against moisture and other harmful agents.
Object of the invention
The principal object of the present invention is to provide a fastening means for sheet materials of the kind described which is easily applied to provide a good seal, and which may be removed without destruction of the installation. Such a fastening means may facilitate the provision of a casing for pipes and conduits which may readily be fitted in situ around existing pipes to provide a good seal against fluids, and which can be removed and re-used, and may allow lighter casing materials to be used.
Summary of the invention
The invention provides a joining means for resiliently flexible sheet materials, the joining means having a slot opening to the exterior thereof and a wall of the slot having at least one inwardly-directed tooth formed thereon. By "inwardly directed tooth" I mean a ridge or other means which provides a surface against which a body being withdrawn from the slot can abut to prevent further such withdrawal, for example a tooth which is inclined inwardly of the slot. In the preferred form of the invention the joining means has two such slots opening to opposite sides of the joining means.
Brief description of the drawings
In the accompanying drawings, Figure I is an end
view of a joining means according to the invention.
Detailed description of the preferred embodiments
The joining means of Figure I is a strip of extruded
aluminium having a central spine 16 between two
lateral slots 17,18 formed between an outer cap 19
and an inner base 20. The slots are constructed at
their openings by the edge portions 21, 22 of the cap
and inwardly-directed teeth 23,24formed on the
base.The general thickness of the extrusion is 1.2mm and the dimensions and angles referenced in
the drawing are:
5 = 19.5mm, 26 = 9.3mm, 27 = 5mum, 28 = 220,29 = 300,30 = 13.3mm,
31 = 4.7mm, 32 = 33.5mm, 33 = 3mm, 34 = 5mm, 35 = 1 mm, 36 = 20" and 37 = 450 To fit the joining means, opposite edges of a sheet of casing material are folded over as shown at 3839 in
Figure I so as to be pushable into slots 17, 18 with the edge faces 40,41 of the sheet in contact with the base 20.Since casing materials in use are resiliently flexible the folds 38,39 exert constant pressure on the walls of the slots and the edge faces 40,41 of the casing abut against the teeth 23, 24 to prevent the casing from slipping out of the slots. When it is desired to remove a casing from a pipe the joining strip and the casing are disengaged longitudinally, thus allowing the edges of the casing to spring free.
Thus the casing is readily assembleable without the use of adhesives, welding or rivets and may easily be disassembled and reassembled using the same components. For the best sealing of the joins, a mastic compound or neoprene may be placed in the slots before the edge portions of the casing are inserted. When the joining strip is used with a casing made of sheet metal such as stainless steel, a very light guage of metal, such as 0.5mm, may be used, thus facilitating the use of high quality materials at a relatively low price.
