The use of figure numbers and/or figure reference labels in the claims is intended to identify one or more possible embodiments of the claimed subject matter in order to facilitate the interpretation of the claims. Such use is not to be construed as necessarily limiting the scope of those claims to the embodiments shown in the corresponding figures.
It should be understood that the steps of the exemplary methods set forth herein are not necessarily required to be performed in the order described, and the order of the steps of such methods should be understood to be merely exemplary. Likewise, additional steps may be included in such methods, and certain steps may be omitted or combined, in methods consistent with various embodiments of the present invention.
Although the elements in the following method claims, if any, are recited in a particular sequence with corresponding labeling, unless the claim recitations otherwise imply a particular sequence for implementing some or all of those elements, those elements are not necessarily intended to be limited to being implemented in that particular sequence.
The present invention provides a securing strap for securing the waste hose from an RV or other vehicle to a standpipe for a waste disposal containment system. The standpipe can be oriented in any direction; as described herein, however, the standpipe extends vertically. In an exemplary use, referring to
Strap assembly 100 includes a horizontal strap 110 that wraps around vertical standpipe 60, with a pivoting strap 170 that is attached to horizontal strap 110 at pivot pins 111 and extends over elbow 50. Pivoting strap 170 can be tightened to force elbow 50 downward into vertical standpipe 60 to prevent elbow 50 from popping out of vertical standpipe 60 while effluent is being pumped through elbow 50 to standpipe 60.
Referring to
A first partially toothed cutout 120 is formed proximate to first end 112. Cutout 120 is generally oblong in shape with a plurality of inwardly extending teeth 122 formed along the top 124 of cutout 120. Similarly, a second partially toothed cutout 126 is formed proximate to second end 114. Cutout 126 is generally oblong in shape with a plurality of inwardly extending teeth 128 formed along the bottom 130 of cutout 120. It is noted that teeth 122, 128 are located on opposing sides of their respective cutouts 120, 126.
Approximately ⅓ the length L of strap 110 from first end 112 is a first through-opening 132 and approximately ⅓ the length L of strap 110 from second end 114 is a second through-opening 134. Through-openings 132, 134 are attachment points for pivoting strap 170. Optionally, indicia 136 can be provided proximate to one of through-openings 132, 134 as an assembly guide for a portion of pivoting strap 170 to ensure proper assembly of pivoting strap 170 with horizontal strap 110.
Referring to rear face 118, optionally, a central portion 140 of strap 110 includes a textured surface, such as a plurality of vertical ribs 142, that are used to enhance friction between strap 110 and standpipe 60.
Referring to
First end 112 and second end 114 are advanced into their respective slots 154, 156 until cutouts 120, 126 overlap. A ratchet wheel 158 has a toothed portion 160 that is inserted into a recess 162 in body 152 behind both first end 112 and second end 114 such that teeth 164 in toothed portion 160 engage teeth 122, 128 of cutouts 120, 126, respectively. A rotating knob 166 extends from in front of first end 112 and second end 114, through both cutouts 120, 126, to engage toothed portion 160 such that, as knob 166 rotates, toothed portion 160 rotates and moves first end 112 and second end 114 in opposite directions, either tightening or loosening strap 110 around standpipe 60, depending on the direction of rotation of knob 166. While exemplary ratchet mechanism 150 is shown and described, those skilled in the art will recognize that other types of strap tightening mechanisms can be used in lieu of ratchet mechanism 150.
Pivoting strap 170 includes a first, or right, strap portion 172, shown in
A dogleg 180 extends from pivot end 176 and terminates at a ratcheting end 182. Dogleg 180 serves to move the upper part of pivoting strap 170 off the central axis of standpipe 60 and toward the connection joint 52 of elbow 50 to provide better leverage to force elbow 50 downward onto standpipe 60.
Ratcheting end 182 includes a first partially toothed cutout 184 formed therein. Cutout 184 is generally oblong in shape with a plurality of inwardly extending teeth 188 formed along the bottom 190 of cutout 184.
As shown in
Referring to
A dogleg 195 extends from pivot end 194 and terminates at a ratcheting end 196. Similar to dogleg 180, dogleg 195 serves to move the upper part of pivoting strap 170 off the central axis of standpipe 60 and toward the connection joint 52 of elbow 50 to provide better leverage to force elbow 50 downward onto standpipe 60.
Ratcheting end 196 includes a first partially toothed cutout 197 formed therein. Cutout 197 is generally oblong in shape with a plurality of inwardly extending teeth 198 formed along the top 199 of cutout 197.
As seen in
To install assembly 100, horizontal strap portion 110 is first slid over standpipe 60. Next, elbow 50 is inserted into standpipe 60. Pivoting strap 170 is lifted up and pivoted over elbow 50, toward connection 52. Ratchet mechanism 150 is tightened to secure horizontal strap 110 around standpipe 60. Then, ratchet mechanism 150′ is tightened to force elbow 50 downward into standpipe 60 to securely fasten elbow 50 into standpipe 60.
To remove elbow 50 and assembly 100 from standpipe 60 after effluent is discharged into standpipe 60, ratchet mechanism 150′ can be loosened and pivoting strap 170 can be pivoted away from elbow 50. Elbow 50 can be removed from standpipe 60 and ratcheting mechanism 150 is loosened from standpipe 60 so that assembly 100 can be lifted up standpipe 60 and removed.
It will be further understood that various changes in the details, materials, and arrangements of the parts which have been described and illustrated in order to explain the nature of this invention may be made by those skilled in the art without departing from the scope of the invention as expressed in the following claims.
