Description
SPECIFICATION
Washer
This invention relates to a washer, and more particularly a washer which provides a seal between a head of a fastener on which the washer is received, and a surface onto which thefastenerextends.
According to one aspect of the invention we provide a washer comprising first, second and third parts, the first part being sandwiched between and bonded to each of the second and third parts, and the first part being made of a material more rigid than the second and third parts.
For example,thefirst layer may be made of metal or rigid plastics, to give the washer rigidity, whilst the second and third layers may each be made of a resilient material, which may be a natural rubber, synthetic rubber or a mixture of natural and synthetic rubbers, to provide a seal.
In each case, a suitable bonding agent or adhesive will need to be chosen to bond the second and third partstothefirstpart. One example of a suitable adhesive is a Polyamide resin adhesive.
Sealing washers arewell knowninthe construction industry, particularly where preformed metal sheet is used for cladding and roofing, the sheet being secured to studs or purlins by fasteners.
It is desirable to provide a seal between each of the heads ofthe fasteners and the metal sheets. Sealing washers are known in which a sealing material is moulded to one side of a more rigid material, with part ofthe material as it is moulded, passing through an opening ofthe washer and engaging on opposite side of the more rigid material part, but the moulded sealing material tends to become displaced by compression forces to which it is subjected as the fastener is tightened.
Furthermore, production of such washers is expensive.
The present invention overcomes these problems because the strength of the joints between the first and second and first and third parts of the washer can be, by selecting the correct bonding agentor adhesive, adequately strong to resist compression forces which tend to displace the second and third layers, and furthermore, a washer in accordance with the present invention is more economicto produce than known sealing washers in which sealing material is moulded into place.
Preferably the second and third layers are made in a material or as a mixture of materials, selected from thefollowing group of materials namely:
Thermoplastic elastomer/rubber Neoprene rubber Ethylene Proplene rubber
Styrene-Butadiene rubber
Nitrile rubber
Natural rubber
Silicone rubber
The second and third parts may be bonded to the first part by cold bonding that is, using a bonding agent or adhesive which bonds at ambient temperatures, or may be bonded to the first part by hot bonding, that is using a thermosetting bonding agent or adhesive.
Hot bonding is sometimes known as "vulcanising" although itwill be appreciated to those learned inthe art,thatvulcanising isthe process of hardening rubber by adding sulphur orother agents, usually when the rubber is at an elevated temperature.
The term "hot bonding " used in this specification is thus intended to cover the process of heating the rubber in orderto promote setting ofthe bonding agent or adhesive i.e. the process commonly, but incorrectly, known as "vulcanising".
The first, second and third parts ofthe washer are preferably all annular providing an opening, preferably a generally central opening,to receive a fastener.
Alternatively, the washer may be of other shapes, such as part spherical, corrugated, but shaped orL shaped, and may have an opening to receive a fastener.
The first, second and third washer parts may be planar, orat leastthe second and/orthird part presents a convex surface,the convex surface ofthe washer in use, being engaged by the head of a fastener.
Preferably however, the firstwasher part is of a dished configuration, and one ofthe second and third washer parts, at least when bonded to the first washer part, presenting a convex surface, whilst the otherofthe second and third washer parts, at least when bonded to the first washer part, presents a concave surface.
However, it will be appreciated that where the first washer part is dished, as the fastener is tightened, the washer may be flattened.
The second and third parts may be co-extensive with each other and with the first part or may not be co-extensive with each other and extend over different regions ofthe first part.
For example, the second and third parts may both extend over opposite faces ofthe first part around the opening therein whilstthethird part alone may extend to the periphery of the first part on one face thereof whilstthe second part may have an outer periphery spaced within the outer periphery ofthe first part.
According to a second aspect of the invention we provide a combination of a fastener having a head and a shank, and a washerin accordance with the first aspect ofthe invention, the shank of the fastener passing through a generally central opening ofthe washer, and the head of the fastener engaging one of the second and third washer parts.
According to a third aspect ofthe invention we provide a construction comprising a first member and a second member,thefirst and second members being secured together by a fastener passing through an opening in the first member into the second member, a washer in accordance with the first aspect ofthe invention being interposed between a head ofthe fastener and the first member to provide a seal therebetween.
The first member may be generally sheet-like, such as preformed metal cladding or roofing sheet, and the second member may be a stud or purlin member.
Thus the construction in accordance with the third aspectofthe invention may comprise a building construction.
The invention will now be described with the aid of the accompanying drawings in which:
Figure lisa plan view of a washer in accordance with the invention, Figure2 is a side sectional viewthroughthe washer of Figure 1, in use, and, Figures 3a, 6,to 7a, are respectively plan and sectional views through other embodiments ofthe invention.
Referring to Figures 1 and 2 of the drawings, a washer 10 comprises three parts, namely a first centre part 11, a second top part 12 and a third bottom part 13.
Each ofthethree washer parts 11,12, and have aligned generally central openings 14and thus are of generally annularform.
Thefirstwasher part 11 is preferably made in metal, but could be made in any other material more rigid than the second and third washer parts 13 and 14. For example, thefirst more rigid washer part 11 could be made in a rigid plastics material if desired.
The second andthird washer parts 12and 13are preferably made from a resilient material. In one example, the second and third rubber parts are made from thermoplastic elastomer/rubber, Neoprene rubber, Erthylene Proplene rubber,
Styrene-Butadiene rubber, Nitrile rubber, natural rubber, or a silicon rubber, or a mixture of any of these, orone ofthe second andthird parts may be made of one of these mixtures or other of the second and third parts may be made from a different one of these materials.
Both ofthe second and third washer parts 12 and
13 are bonded to thefirstwasher part 11 by a suitable bonding agent or adhesive.
Such a bonding agent or adhesive may permitcold bonding between thewasher parts 11, 12 and 13 or heat may be required to premote setting, if the adhesive is a thermosetting adhesive for example.
One example of a suitable adhesive is a polyamide
resin adhesive.
As can be seen in Figure 2, the opening 14 provided in each ofthethreewasher parts 11,12,13, receivesashank i6ofafastenerl7,thefastenerl7 having a head 18 which engages an upper surface 19 of the second washer part 12.
The fastener 17 secures together a first member 20 which, in the present example, comprises a preformed metal sheet of a building construction, and a second member 21, which in the present example comprises a stud or purlin of a building. The shank l6ofthefastener passes through an opening 22 inthefirstmember20and into an aligned opening 23 in the second member 21.
twill be appreciated that as thefastener 17 is tightened, the washer 10 will become firmly sandwiched between the head 18 of the fastener 17, and the first member 20, and because of the nature of the material of the second and third washer parts 12 and 13, effective sealing will be achieved between the head 18 ofthe fastener and the second washer part 12, and between the third washer part 13 and the first member 20, whilst the first washer part 12, being of more rigid material, will givethewasher 10 adequate mechanical strength and rigidity. In addition, sealing will be achieved between the shank 16 ofthe fastener 17 and each ofthe second and third washer parts 12,13, astheyare deformed into sealing engagement with the shank 16 as the fastener 17 is tightened.
To assist sealing, it can be seen that the upper surface 19 of the second washer part 12 with which the head 18 ofthefastener 17 engages, is siightly convex, whilst the undersurface 24 of the third washer part which engages thefirst member 20, is slightly concave. The first washer part 11 is itself slightly dished, and the second and third washer parts 12 and 13 assumetheirconvex/concaveshape when they are bonded to the first washer part 11.
Thus any moisture e.g. rain,falling on the upper surface 19 ofthewasher 10, will nottendto move towardsthe shank 16 ofthefastener, but will tend to run from the convex surface 19.
Other configurations of washer embodying the invention are shown in Figures 3a, 3b, to 7a, 7b.
Figures 3a and 3b show a washer similartothat shown in Figures 1 and 2 but where the washer is of a flat annularshape. The second andthirdwasher parts 12, 13, are co-extensive with the first washer part11.
Figures 4a, 4b show a washer which is rectangular in plan view and of corrugated shape in cross section. The first second and third washer parts 11, 12, 13, are not co-extensive, the second washer part 12 extending overthefirstwasher part 12 only in the region around the opening 14whilstthethirdwasher part 13 extends to the outer periphery of the first washer part on the bottom face thereof.
Figures 5a and Sb show a washerwhich is rectangular in plan view and of truncated shape in cross section. Again the second and third washer parts 12 and 13 are not co-extensive and the second washer part 12 extends over onlythe central region ofthefirstpart 1 1,whilstthethird part 13 coversthe whole ofthe bottom surface ofthe first part 11.
Figures6a and 6b showawashersimilartothatof
Figure 1 but of part spherical shape. The first second andthird washer parts 11 and 13 are co-extensive.
Figures 7a and 7b show another modification in which the first second and third washer parts are co-extensive but in this case, the first part is square in plan view and generally V shape in cross section, the root ofthe V lying on a diagonal ofthesquare.
If desired,the washer may have other shapes to those described hereinbefore.
Although the invention has been described in relation to a building construction, of course a washer 10 in accordance with the invention may be used in combination with any other fastener and in any other application as required.
The features disclosed in the foregoing description, in the following claims, orthe accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, ora class or group of substances or compositions, as appropriate, may separately or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
