Description
BAC~GROUND OF THE INVEN~ION
Field of the Invention This invention relates to safety ~traps for component~
su~penda~ly ~upported on or u~der motor vehicles.
Especially, the invention relates to safety straps for gasoline tanks w~ich are supported from the underbody of motor vehicles usually in a position open to the ground.
Acknow] e~g~ent of Prior Art Gasoline tanks were, over a ver~ long period of auto~otive hi~tory, ~anufactured of metal. They h~ve been supported in convenien~ hollows or cavi~ies of the mo~or body. These hollows or cavities are usually open to the ground beneath. One reason for this is that if a gasoline tank-fractures the ga~oline may run-harmle~sly away with less ri~k o~ causing fire within the vehicle. Considerable e~phasis has been laid on back-up supporting sy~tems ~or the gas tank bec~u9e, should a gas tank should break free of its prLmary support systems and drag on a road surface, any resulting sparks may be very dangerous indeed. Therefore, it ha~ been conventional to provide additional back-up safety ~traps to hold the gas ta~k, should the primary support system fail. These back-up ~afety straps have conventionally been made from metal stampings.
More recently, some gasoline tanks are manuf~c~ured from ~olded plastic material to mitigate the possibility of sparks. ~t has, however, been thought nece.~sary to continue using metal safety straps. The necessity of this is possibly due to the strength of the strap which ~ay be required under unu~ually disadvantageous con~itions. T~e 30 weight o~ a ~ull ga~ tank may ea~ily be i~ the region of 150 pounds. This weight must be reliably supported over a long period of ~ay several years under conditions which may range from, say., ~ore than 100~F (in sum~er when great heat is p~oduced from the exha~st or reflected from hot ro~d s~rface~) to, say, less than -10~F or -20~F (in the depths of ~inter). In some climates one or both of the~e temperatures may be even more extreme. Still further, the ageing of plastic materials results in b~ittleness and lack of strength.
Thus, it has not been thought prac~icable to use plastic ~aterials for support straps for gas tanks in spite of the various difficulties inherent in the use of metal straps .
The stamped metal saf~ty straps have various problems associated with them. They are quite expensive to ~5 manufacture in that it is necessary to make a metal stam~ing, provided with a hinge pin at o~e end by ~eans of further manufact~ring processes such as riveting or otherwise fixing a cylindric~l housing for the hinge pin to one end of the strap and inserting the hinge pin to project 20 fro~ either en~ of the hou~ing. Attachment means must be provided at the other end of the s~rap, for example an aperture for a nut and bolt closure with the vehicle body may be provided. The stamped metal strap must be bent into a shape conforming to the shape of the gas tank. None of these ad~itional ~anufacturing steps are as simple as they first appear. The step of riveting a hinge pin housing to one end of the strap is e~pensive. The hinge pin itself tends to fall out of the ho~sing before installation in the vehicle. This makes handling and storage of the uninstalled straps somewhat of a problem. The ~tep of ~ending the strap into shaped form with the ~as tank provide~ real proble~s.
The metal has a tendency to ~pring ~ack from the shape in whic~ it is bent so that the conformation of shape of the eventually bent strap is never very precise. The process al~o lead~ to a severe b~lrr problem. As a result it is ~'ery frequent that a strap must ~e manually stressed or machined before or during installation by the mechanic installing it.
If it should slip there is a danger of either injuring the mechanic hi~self o~ damaging the gasoline tank. ~ow that gasoline tanks are frequently made of molded plastic materi~l, the danger of damaging the gasoline tan~ and actually rupturing i~ is quite high. It is also necessary, whether the gasoline t~nk is a me~al tank or a molded tank, to provide some padding between the tank surface and the metal strap. Such padding mitigates friction and resulting wear of the gas t~nk d~e to ~ubbing of the strap. In the case o~ molded tanks it may help to prevent the metal strap actually tearing apart the tank. In the case of metal tanks it may help prevent sparks Even though the use of ~etal safety straps has so many di~ficultie~ associated with it, there has been a very real acceptance in the industry that these difficulties are inherent and must be lived with. It has not been thought possible to make substan~ive changes in the manufacture and design of safety straps for gasoline tanks and other ~nder-~ehicle parts such as exhaust systems.
S~MM~RY OF THE INVENTION
The present inventor has addLe~sed the pxoblems in providing more satisfactory, less expensive safety ~traps for use ~ith under-vehicle parts. Most surprisingly he CA 02237029 l998 - 05 - 06 discovered that ~he perceived reasons for the impos~ibility of using molde~ material safety straps may ~ot apply especially when the m~lded material i~ selected from those materials which do not suffer fro~ deterioration under the extreme conditions which occur underneath a car.
~ccording to the invention there is provided an elon~ate sa~ty strap constructed and arranged to e~tend beneath an article supporte~ above the ground by pri~ary support means depending from a supporting body, the safety strap being molde~ in a material selected from the group con~isting of moldable ceramic material, thermosetting plastic~ materials, and thermoplastics materialY to conform generally with the shape of an undersurface of ~aid article in the region of the strap, each end of the strap havi~g a connector molded thereinto to connect the strap to said body.
Preferabl~ the safety strap is of the type having a hinqe at one end and closure means at the other so that it may be open for accessing the component part if neces~ary and reclosable when d~sired. Conveniently, the hinge may be the hinge pin extending at right angles to the strap for location in hinge ~ountings of the structure from which the article is supported. In particular, the article may be a gasoline tank, a muffler, other parts of ~n exhau~t ~ystem or other vehicle compo~ents supported beneath a motor vehicle.
When the article is, for example, a gasoline tank, the safety strap may be manufaot~red ~rom reinforced thermoplastic materials such as nylons, ~or example Celanese 1500 and Zytel 70G43L. Other thermoplastic materials such as li~uid crystal polymers ~vectra B420 ), polyphenylene sulp~ide, ~tc. may also be u~ed. Nylons, which tend to harden on ageing may be especially sui~able.
When the article to be supported is, for example, a muffler system the ~trap may be ~olded from moldable ceramic material or thermo~etting plastic material. Alternat-vely, the~moplastic material having a melting point above 4~0~F my be used. -The straps should, of course, be of sufficient strength to support the tank or other article if the primary suppor~should ~ail. Thus, the 6tra~ or straps must be su~ficiently strong to support loads in the region of 150 lbs depending on the capacity and content of the tank. Clearly loads greater than this may b~ envisaged. It may, therefore, be convenient to form the straps of molded reinforced material.
The reinforcement may be, for example, a fiber reinforcement either oriented or non-oriented. Examples of fibe~
reinforcement are fibergla~, Kevlar lTrademark) or other aramid fiber, graphite and the like.
The invention includes a method of injection molding a back-up safety strap for supporting an article espe~ially a component of a motor vehicle against ~alling sho~ld its primary ~upport fail. The injection ~olding method may comprise forming a mold to conform with the shape of at least the under side of the article with which the safety strap is to be used, locating a hinge pin in the mold, inj ecting moldable material around a mid-portion o~ the hinge pin and ~emoving the molded article from the mold.
Conveniently, provision may be made in the mold to provide an aperture at one end of the safety strap for latching with a ~tructure on ~hich the article is supported by me~ns of a bolt passing through the aperture and a lock-nut.
BRIEF DESCRIPTION OF THE DR~INGS
Embodiment~ o~ the invention are generally illustrated by way of example in the accompanying drawin~s in which:
Figu~e 1 is an exploded view of an e~emplary prior art metal strap for back-up support for a gasoline tanki Figure 2, ~A, 2~ and 2C show a safety strap according to the 1~ invention for back-up suppoLt for a gasoline tanki Figure 3 shows another safety strap according to the invention for back-up support on a gasoline tank;
Figure 4 shows a strap accor~ing to the invention for support of a mu~fler system; and Figure 5 show~ a section of a ~old for molding a safety strap as ~hown in Figure ~.
DETAILEI) I;~ESCRI Pl'ION OF PREFERRED EMBODIMENTS
From Figure 1 it can be seen that a large numbex of parts are necessary in the manufacture of even a very simple strap stamped fro~ metal. A hinge pin 12 is lo~ated only by a clamp 14 riveted by rivet 16 to the bo~y 18 of the strap 10. The strap 10 is provided with a fl.ange 20 at t~e end distan~ from the hinge pin 12. A hole 22 is punched in the ~lange so that the strap may be bolted to the under body 17 of a motor vehicle by bolt 21. A foam pad 11 is provided on the strap 10.
The hinge pin 12 may be located in sockets 13 fixed to ~he underbody 17 of a motor vehicle. A ga~oline tank 15 is ~uppor~ed beneath the underbody 17 by primary supports 19.
~ igures 2, 2A and 2B show a safety strap 30 embodyi~g the invention w~ich is simple in comparison with a ~trap of the prior art. Strap 30 is molded in one piece construction from glass fiber reinforced nylon Zytel 70G43L. The one piece construction of the strap extends around hinge pin 32 to adhere to hinge pin 32 and locate it fi~mly with respect to strap 30. Flange 34 is provided at the end of the strap distant from hinge pin 32 and is molded in the original molding. It is not necessary ~o provide an extra process step to bend flange 34 i~to position. Aperture 36 is provided to accept a ~olt 21 from a under body of a motor vehicle and, again, may be pro~ided in the original mol~ing.
The gasoline tank 15 i~, as in Figure 1, supported beneath the underbody ~7 by pri~ary supports 19.
Figure 3 shows more complex shape o~ a safety strap otherwi~e similar to that of Figure 2. It may, however, be seen from Figure 3 that the configuration of strap 30 ~ay follow the shape of gasoline tank 15 to fit indentations in the tank. This is not convenient or even possible when using a metal strap of the prior art.
Hinge pin 12, shown separa~ely in Figure 2A, may have a knurled central portion for better bonding. The strap 30 itself may ~e ribbed for strength. For example it may have the cross section shown in Figure 2B. Figure 2c ~hows a rigid washer 54 which is molded into the end of strap 30 as ~he flange 34 distant from the hinge. Washer 54 forms a ba~e ~or attachment to the vehicle body.
Figure 4 ~hows a strap which may be a pri~ary ~upport strap for a muf~ler ~olded from a ceramic ~oldable material.
Reference numerals in Figures 3 and 4 represent similar parts to those of Figure 2.
The strap 30~ of Figure 3 has at one end, a washer 54A
~imilar to that of Figure 2C. At the other end a downward leg ~0 of a bLacket 62 is embedded in the end during molding. The strap 30B of Figure 4 has washers 54B at eac~
end. Washers 54B are similar to washers 54 and 54~.
Fi~ure 5 is a section through injection mold ~alves to make a safety strap as shown in Figure 2. The mold includes a cavity 50 ha~ing a bulbous portion 52 at one end and a socket ~or location of a hinge pin 32. At the end of the cavity distant from the bulbous end, a square washex 54 is located in the cavity. The washer 54 forms a firm base and has an aperture for an attachment bolt. Since washer 54 is ~olded into, or at least attached to, the strap, there is red~ed risk of it loss duling transport. The gating for the injection mold may be provided at any convenient location.
