Abstract
Description
- The present invention relates to apparatuses for protecting substrates against corrosion, electrical currents, and other adverse environmental effects.
- Various methods have been proposed in the prior art for protecting a substrate from adverse environmental effects. A typical method used in the prior art is to dispose a viscous grease around the substrate in an attempt to keep adverse environmental contaminants, such as water, from corroding the substrate being protected or providing an electrical path thereto. Another common method used in the prior art has been to apply paint to the substrate. Both of these methods are disadvantageous in that insufficient corrosion protection is afforded, re-entry is difficult, the protection lasts for a relatively short period of time, they are labor intensive, and relatively expensive.
- Debbaut, U.S. Serial Nos. 434,0ll, 504,000, and 507,433, all assigned to the assignee of the present invention and incorporated herein by reference, disclose various containers which are substantially filled with gel material, the container subsequently being disposed in contact with a substrate subsequent to curing the gel. Though these containers are quite effective in protecting substrates, a problem still exists in the art in providing adequate environmental protection to a substrate having a recess therein since condensation oftentimes can still occur within a void surrounded by the recess. Furthermore, some substrates are disposed in installations wherein very little room is available for disposing a relatively large gel filled container thereat so as to completely enclose the substrate to be protected with gel.
- Accordingly, it is an object of the invention to eliminate the above-noted drawbacks and to provide an article for protecting a substrate which is relatively inexpensive to produce, is easy to install over the substrate, lasts a relatively long period of time, and can be made easily re-enterable, if desired.
- These and other objects are achieved by an apparatus which includes a reservoir filled with a gel, the gel comprising a three dimensional open cell network, the gel being elastic, and having finite elongation characteristics, preferably in excess of 200%, and having a cone penetration between l00 and 350 (l0-l mm), more preferably between 200 and 300 (l0-l mm), and most preferably between 250 and 280 (l0-l mm). The reservoir is collapsible and has an open face through which gel can be disposed outward therefrom when a portion of the reservoir is collapsed such that upon collapsing the reservoir, the gel is dispensed through the open side of the reservoir and into a recess of a substrate to be protected such that the gel can completely fill the recess.
- According to an alternative embodiment of the invention, a plurality of reservoirs, either collapsible or non-collapsible, are interconnected by flexible bridging members which allows the use of relatively small reservoirs to be incorporated in an apparatus for protecting a plurality of contact areas on a substrate such that a major portion of the apparatus does not contain gel so as to allow the apparatus to be disposed in installations where very little room is available for protecting the substrate.
- Figures l-4 illustrate various alternative embodiments of collapsible reservoir constructions;
- Figure 5 is a plan view, and Figure 6 is a side view, of a plurality of collapsible reservoirs disposed on an apparatus for protecting a plurality of contact areas of a substrate;
- Figure 7 is a plan view, and Figure 8 is an end view of one preferred embodiment of the invention, this embodiment being particulary useful for protecting contact areas on a modular telephone jack;
- Figures 9 and l0 illustrate an alternative embodiment for protecting contact areas on a modular phone jack;
- Figure ll illustrates yet a further embodiment for protecting contact areas on a modular phone jack, with Figures l2-l5 illustrating various installation steps of the embodiment of Figure ll.
- Figures l-4 illustrate various embodiments of a
collapsible reservoir 2 constructed in accordance with the teachings of the present invention. - Each of the
reservoirs 2 includes agel 3 therein. The gel is preferably one of the types described in Debbaut, U.S. Serial Nos. 434,0ll, filed November l2, l982; 504,000, filed June l3, l983; 507,433, filed June 23, l983; and Chang, U.S. Serial No. 646,555, filed October 3l, l984; all assigned to the assignee of the present invention. In particular, the gel can comprise a urethane, a silicone, or a non-silicone liquid rubber with low or no unsaturation which has been cross-linked, with urethanes and silicones being preferred embodiments. The gel is a material having an open loop three-dimensional network such that it is elastic and has a finite amount of elongation, and is relatively soft. A preferred embodiment is to use a gel having a cone penetration between l00 and 350 (l0-l mm), and an ultimate elongation of at least l00%, as measured in accordance with American National Standard Designation ASTM-D2l7 and ASTM-D638, respectively. Preferably, the cone penetration is between 200 and 300 (l0-l mm), and more preferably between 250 and 280 (l0-l mm). In addition, the ultimate elongation is also more preferably in excess of 200%, and more preferably in excess of 500%. In addition, the gel is also preferably elastic such that it tends to resist deformation and generates a restoration force upon being deformed. - The
reservoir 2 is collapsible such that when subjected to a force indicated by arrow l0, thegel 3 within thereservoir 2 is displaced out of the reservoir through anopen side 4 thereof as illustrated in Figures l-4. In Figure 2, anopen side 7 having a tunnel cross-sectional configuration is formed on a side of thecollapsible reservoir 2, this embodiment allowing a substrate to be protected to be inserted and/or removed from the reservoir from its side. In addition, it is preferable that the gel have an ultimate elongation sufficiently large such that the gel does not tear when the reservoir collapses. - Preferably, the
collapsible container 2 is made of a material, or has an internal construction such that, thegel 3 has an adhesion strength thereto greater than the gels cohesive strength, with the adhesive strength of the gel to the substrate contact area it is intended to protect being preferably less than its cohesive strength and its adhesive strength to the substrate member, to facilitate re-entry. - In the embodiment of Figure l, the
open side 4 is substantially circular in configuration, though elliptical, rectangular, or other shapes can be used where the substrate contact area to be protected is similarly shaped. In the embodiment of Figure 3, theopen side 4 has a tapered skirt construction which has the advantage of enlarging a substrate contact area which can be surrounded and protected while minimizing a volume of thegel 3 required to fill thecollapsible reservoir 2. - Each of the embodiments of Figures l-4 utilizes a
collapsible reservoir 2 which collapses downward, with the embodiment of Figure l having a telescopic profile having a largest cross-sectional area thereof forming the open side through which the gel is dispensed, with a next smallercross-sectional area 7 being adjacent thereto, with the smallest cross-sectional area l5 being on an opposite end of the reservoir than is theopen side 4, as illustrated. Accordingly, if subjected to a force l0, the reservoir collapses such that the section l5 can be received within thesection 7 which can be received within the section l7, if total collapsibility is a design criterion. Alternatively, the reservoir can be constructed such that only thesection 5 collapses within thesection 7. Upon collapsing, this section l5 acts substantially like a piston, this being the mode of collapsing in the embodiments of Figures 2 and 3 whereinpiston section 8 collapses within larger section l7 formed so as to define theopen side collapsible reservoir 2 has a corrugatedouter surface 24 which allows an accordian-type compression to occur when subjected to a force l0 so as to dispense gel out of theopen side 4. Each of the embodiments of Figures l-4 functionally allows a gel to be dispensed from thereservoir 2 upon being subjected to a force l0 such that the gel is available for filling a recess on a substrate having a contact area incorporating a recess to be protected. - The remaining figures illustrate practical embodiments of the invention, with Figure 5 illustrating a plurality of
collapsible reservoirs 2 disposed in line on a strip ll, with the strip ll having a pressure sensitive adhesive l2 on a surface thereof. In use, the strip ll is disposed in contact with a substrate having a plurality of contact areas thereon to be protected such that thecollapsible reservoirs 2 respectively line up with respective contact areas to be protected, and then the collapsible reservoir is subjected to a force causing the reservoirs to at least partially collapse so as to partially dispense gel therefrom so as to totally incapsulate the contact areas to be protected. - A practical embodiment of the invention will next be described with reference to a substrate corresponding to a telephone
modular jack 5, illustrated in Figures ll-l6. Referring to Figure ll, the apparatus l includes first and secondcollapsible reservoirs 2 and third and fourth reservoirs l4, the reservoirs l4 being either collapsible or non-collapsible, though in the embodiment shown the reservoirs l4 do not need to be collapsible. Thereservoirs 2 each have a substantially rectangular cross-sectional profile l3, since arecess 40 on aback side 26 of thejack 5 also has a rectangular cross-sectional profile. The recess on theback side 26 of thejack 5 corresponds to a cavity through which contact screws orbolts 28 extend, thescrews 28 being held in place by ametallic mounting bracket 43, shown in Figure l6. To environmentally protect the contents of thejack 5, thescrews 28 andbrackets 43 must all be protected. - The apparatus l further includes flexible briding members l9 interconnecting each of the
reservoirs 2, l4. To install the apparatus l on thephone jack 5 so as to protectcontact bolts 28 andbrackets 43 and areas therearound from corrosion and various environmental contaminants, the jack is first loosened from its mounting surface, such as a wall, as illustrated in Figure ll. Subsequently, thecollapsible reservoirs 2 are slid behind thejack 5 as illustrated in Figure l2 such that the rectangular cross-sectional profiles l3 of thecollapsible reservoirs 2 are disposed overrecess contact areas 40 on theback side 26 of thejack 5, as illustrated in Figures l2 and l6, and subsequently the phone jack is re-secured to its mounting surface. Thereafter, the additional reservoirs l4 are wrapped around thejack 5 as illustrated byarrow 30 in Figure l4 and disposed over ends of the contact screws orbolts 28. In this embodiment, it is not necessary to completely remove thejack 5 from its mounting surface to install the collapsible reservoirs around the recesses, though the jack can be so removed if desired. Rather, all that is required is that the jack be loosened enough so that thereservoirs 2 can be slid behind the jack. Re-securing thejack 5 tightly to its mounting surface by tighteningscrews 44 as illustrated in Figure l3 provides the force means l0 for collapsing thereservoirs 2. - Since the screws or
bolts 28 protrude from a front surface of thejack 5, thegel 3 is readily elastically displaced around ends of the screws orbolts 28 and maintained in close and conforming contact therewith so long as held under some force by some additional force means l0', this force means being provided byjack cover 22 which is screwed over thephone jack 5, as illustrated in Figure l5. Preferably, the gel has a tacky surface so as to facilitate adhesion of the gel to the contact area of the substrate to be protected while being held under compression. - The embodiment of Figures ll-l6 is further advantageous in that a plurality of the
reservoirs 2, l4 are interconnected by flexible bridging members l9 which allows a plurality of substrate contact areas to be protected utilizing a minimum amount of gel with the apparatus l occupying a minimum amount of room, as compared to other prior art constructions wherein relativelylarge reservoirs 2 are provided for enclosing entire substrates so as to protect various contact areas thereon. - Figures 7-l0 illustrate further alternative embodiments of the invention. In the embodiment of Figures 7 and 8, the apparatus 3l includes flexible bridging members l9 arranged such that eight reservoirs in total are included with the apparatus. In use, the
jack 5 is removed from its mounting surface rather than simply loosened as in the embodiment of Figures ll-l6, and the apparatus 3l is disposed on the mounting surface such that thereservoirs 2 are disposed at a location such that they will come in contact with substrate recesscontact areas 40 to be protected when thejack 5 is replaced on the mounting surface, with holes l6 being provided on the flexible bridging member for providing a means of properly orienting the apparatus 3l, and in particular the rectangular shaped open sides l3 of thecollapsible reservoirs 2. The holes l6 will line up with attachment holes 2l (Figure ll) through which screws extend for attaching thephone jack 5 to its mounting surface and providing a force means l0. The force means l0 causes the reservoirs to collapse, as previously explained. Subsequent to re-attaching the phone jack to its mounting surface, reservoirs l4 are pivoted about a l80° semicircle in a manner similar to that illustrated byarrow 30 in Figure l4 so as to cover all the exposed and protruding contact screws orbolts 28. The embodiment of Figure 3l is particularly advantageous in that it comprises only a single article, is easily installable, and provides an indication means l6 confirming proper orientation of the apparatus. In the apparatus of Figures ll-l4, orientation indication means is provided by the shape of the rectangular shaped open sides l3 of thereservoirs 2 which corresponds to the rectangular shape of thecontact areas 40. - The embodiment of Figures 9 and l0 comprises first and
second pieces first piece 32 containing a plurality ofcollapsible reservoirs 2 having thegel 3 disposed therein, thepiece 32 being adapted for being located on theback side 26 of thephone jack 5 after its removal such that upon re-attachment of thephone jack 5 each of thereservoirs 2 is collapsed so as to exert gel therefrom intocontact area recesses 40 on the back side of thephone jack 5. Subsequently, thepiece 33 is disposed over the front side of the phone jack so as to encapsulate each of the bolts orscrews 28, with the force means to thepiece 33 being preferably provided by pressuresensitive adhesive 45 located on a side of thepiece 33 in contact with thejack 5. Additional force means can also be provided by re-attaching thecover 22, as illustrated in Figure l5. - The embodiment of Figures 9 and l0 is advantageous in that relatively few pieces are required to ade quately protect a phone jack, indication means is provided to facilitate proper installation thereof, and a plurality of reservoirs are interconnected with flexible bridging members thus reducing the component parts required to adequately protect the
phone jack 5. - It is to be understood that the inventions of providing collapsible reservoirs are useful in a wide variety of applications, and not specifically limited to the particular application of protecting a phone jack, as described herein, and that the invention of providing a plurality of small reservoirs interconnected by flexible bridging members so as to allow encapsulation of opposite surfaces of a
substrate 5 in a fast and efficient manner is also not limited only to the embodiment of the protection ofphone jack 5. The invention is particularly applicable to any application where a substrate has a contact area which has a recess which requires protection, or in any application where it is desired that gel be pumped into a location relatively remote from a surface of the substrate to which the reservoir is attached, the invention also being useful in any application where opposite sides of a substrate need to be protected in a fast and efficient manner. Accordingly, the invention is to be limited only by the appended claims.
