FIG. 1 provides an example of the prior art side rail fence 1 commonly available in the market place. This type of fence 1 is commonly used by ranchers and farmers for fencing livestock in or out. It is made using vinyl or vinyl derivative for improved weather resistance, decreased weight and relatively high strength. No additional hardware and a minimum of tools are necessary to install this type of fence thereby increasing its desirability for those requiring a fence. Similarly, the fence may also be produced in ascetically pleasing variations for use by home owners in applications that honor the wooden picket fences of yesterday without requiring carpentry skills for installation. U.S. Pat. No. 5,601,278 and U.S. Pat. No. 4,202,532, incorporated by reference herein, provide more background on fences of this type, as are known to those skilled in the arts. -
FIG. 2 presents a top inside view of afence post 3, with the fence post cap 4 removed, to allow inspection of therail 5 inserted into thefence post 3. As illustrated inFIG. 2 , therail 5 is allowed a limited amount of movement within thefence post 3 but is restricted from withdrawal from thefence post 3 by thelocking tabs 7 which are resilient and are said to be “self-locking.” - As shown in
FIG. 3 , the fence 1 is assembled by sliding therail 5 into thefence post slot 6. During insertion of therail 5 into thefence post slot 6, thelocking tabs 7 are depressed into thefence rail 5 and slide past the wall of thefence rail slot 8. After insertion, thelocking tabs 7 extend out and self-lock into place, thus restricting the removal of therail 5 from thefence post 3. This system is desirable for construction and installation as demonstrated by the large number of rail fences 1 sold in the market. To date, however, no product is known to be available to allow an installer or fence owner to retract arail 5 from thefence post 3 without damaging or destroying the self-locking mechanism of thefence rails 5. -
FIG. 4 illustrates afence rail retractor 10 allowing withdrawal of arail 5 from afence post 3 without damage to the self-locking mechanism of therail 5. Theretractor 10 is composed of a set of handles each having aretractor blade 12. Theretractor blade 12 is formed of resilient material providing adequate flexibility for theretractor blade 12 to engage and slide into thefence post slot 6 having afence rail 5 positioned therein. Plastic and thin steel are two types of materials that may be used for production of the retractor blades. The thickness of the blade may range from 0.001 inches to 0.015 inches which has been found to allow it to fit between therail 5 and theslot wall 8 of thefence post slot 6 upon insertion into thefence post 3, in most installations. The surface of theretractor blade 12 is such that it is relatively smooth as to allow theretractor blade 12 to slide into thefence post slot 6 while positioned between thefence rail 5 and fencepost slot wall 8. - The angled frontal portion of the
retractor blade 13 allows theretractor blade 12 to slide between theslot wall 8 of thefence post 3 and therail 5 for insertion into thefence post slot 6. As theretractor blade 12 slides in, the angled portion of theretractor blade 13 is more likely to meet and slide up and over thelocking tabs 7 to allow full insertion of theretractor blade 12. Aretractor blade 12 having a straight front portion has a tendency to meet and “bind” with or on thelocking tab 7. During removal of thefence rail 5, theresilient rectractor blade 12 provides the necessary force against the self-locking tab 7 to depress thelocking tab 7 and allow removal of therail 5 from thefence post 3. The rail fence retractor as illustrated inFIG. 4-8 has an angle in the range of 33-35 degrees. Other acceptable alternative angle ranges are in the range of 1-60 degrees. -
FIG. 5 depicts an interior side view of oneretractor handle 11 andretractor blade 12 to illustrate the interior surface of theretractor blade 12. As shown, theretractor blade 12 is simply mounted to theretractor handle 11 usingscrews 16. Other methods and means for securement of the retractor handles 11 to theretractor blades 12 are known to those skilled in the art and not described further herein. Although not shown, it is within the scope of this disclosure to include aretractor blade 12 andretractor handle 11 which are integral and produced as one-unit or element. -
FIG. 6 illustrates therail fence retractor 10 positioned at thefence post 3 prior to extraction of therail 5. Theretractor strap 14, which may be used with theretractor 10, improves operation of theretractor 10 by fixing the position of the retractor relative to thefence rail 5 andfence post 3. Fixing the position of theretractor 10 allows the user to firmly and conveniently grab therail 5 to remove it from thefence post slot 6 by application of a lateral force. Using theretractor 10 without the straps requires the user to hold theretractor 10 in place while removing therail 5. As shown, theretractor 10 is paired with aretractor string 15 which provides a convenient way to keep both handles and blades of theretractor 10 paired together and during rail removal, fixes the upper position of theretractor 10 to thefence post 3. In another embodiment, not shown, thestring 15 may be replaced with asecond retractor strap 14. The retractor strap(s) 14 may be further improved with Velcro ends allowing quick and convenient tightening and re-adjustment. Other methods and means for conveniently keeping theretractor 10 paired together and allowing fixed positioning of theretractor 10 to thefence post 3 will be apparent to those skilled in the art and are within the scope of this disclosure. -
FIG. 7 is a cut-away view of therail fence retractor 10 positioned at thefence post 3 prior to extraction of thefence rail 5. As shown, thelocking tabs 7 are engaged with and positioned interior of theretractor blades 12.FIG. 8 illustrates theretractor blades 12 depressing thelocking tabs 7 as therail 5 is pulled out of thefence post slot 6 thereby bypassing or “unlocking” the self-locking function of thelocking tabs 7 without destroying or damaging thelocking tabs 7, thefence post 6 or therail 5. -
FIG. 9 depicts an interior side view of another embodiment of theretractor handle 11 andretractor blade 12 to illustrate another method of attaching theretractor blade 12 to theretractor handle 17. In this embodiment, the retractor handle 17 has been vertically divided into two separate sections. A ninetydegree angle 18 has been placed in the posterior portion of theretractor blade 12 for insertion between the two separate sections of each retractor handle 17. This embodiment improves the securement of the blade within theretractor handle 17 and ensures that the interior surface of theblade 12 is not interrupted by the securement means as shown inFIG. 5 . Thescrews 16 are then inserted into both sides of theretractor handle 11, perpendicular to the ninetydegree angle 18 in the blade and parallel with the surface of theretractor blade 12 facing therail 5. This embodiment of the invention may also be practiced by placing avertical groove 19 in the retractor handle 11 to simulate sectioning the handle and then inserting the ninetydegree angle 18 into saidgroove 19 prior to securement. Other securement means including bolts or glue may also be used without departing from the spirit or intent of the disclosure.FIG. 9 also illustrates a locking clasp which may be attached to theretractor string 15. The lockingclasp 9 is intertwined withretractor string 15. The lockingclasp 9 may be adjusted on theretractor string 15 for more or less slack; releasing therail 5 from thefence post slot 6 sometimes requires a high level of force to be applied to thefence rail 5. This energy release is transferred to thefence rail retractor 10 upon the release creating an opportunity for thefence rail retractor 10 to bounce or rebound erratically. Adjusting the lockingclasp 9 to allow little slack in theretractor string 15 reduces the bounce or rebound. - It should be noted that the present invention is not limited to the specific embodiments pictured and described herein, but is intended to apply to all fence rail retractors. Modifications and alterations from the described embodiments will occur to those skilled in the art without departure from the spirit and scope of the present invention.
