- the present invention overcomes the problems associated with the prior art, by providing a fastener that is easy to use, dependable, durable, and easy to wash and disinfect.
- numerous specific details are set forth (e.g., design of specific parts) in order to provide a thorough understanding of the invention. Those skilled in the art will recognize, however, that the invention may be practiced apart from these specific details. In other instances, details of well-known manufacturing practices and components have been omitted, so as not to unnecessarily obscure the present invention.
- the invention can also be used in fields other than agriculture, including, but not limited to, personal, household, general industrial, and/or any other fields where fastening of devices is desirable. In such applications, the size, strength, and other characteristics of the fastener can be scaled for the particular application.
- FIG. 1 is a perspective view of a fastener 100 shown securing a feeder 102 to a wall 104 according to one example embodiment of the present invention.
- Feeder 102 includes an opening 106 that is aligned with another opening 108 (shown in FIG. 2 ) formed in wall 104 .
- fastener 100 is simultaneously disposed through both openings 106 and 108 .
- feeder 102 is shown as being a creep feeder.
- feeder 102 represents any type of container (e.g., food dish, water dish, parts container, etc.) that would be desirable to removably attach to an object.
- wall 104 represents any type of object (e.g., wall, cage, fence, pen, etc.) onto which it would be desirable to removably attach a container or other object.
- fastener 100 would pass from outside of the pen, between the bars of the pen, and through opening 106 .
- fastener 100 is provided in combination with instructions 110 for using fastener 100 to secure two objects together (e.g., securing feeder 102 to wall 104 via fastener 100 ).
- FIG. 2 is a side view of fastener 100 securing feeder 102 to wall 104 .
- Fastener 100 includes a push member 200 , a rigid shaft 202 , an engaging member 204 , a biasing member 206 , and an anchor 208 .
- Push member 200 and anchor 208 are coupled to opposite ends of rigid shaft 202 .
- Engaging member 204 is slidably disposed on rigid shaft 202 between push member 200 and anchor 208 .
- Biasing member is disposed between push member 200 and engaging member 204 .
- Push member 200 includes a first side 210 and an opposite second side 212 .
- First side 210 provides a relatively large flat surface configured to comfortably disperse force exerted thereon by a user's hand when push member 200 is urged against.
- Second side 212 includes a seat 214 onto which biasing member 206 is stabilized and centered with respect to rigid shaft 202 , which passes therethrough.
- rigid shaft 202 is a bolt having a first end 216 , an opposite second end 218 , and an intermediate section 220 disposed therebetween.
- First end 216 is a bolt head that is fixed to push member 200 .
- Second end 218 includes a thread set 222 that facilitates the coupling of anchor 208 thereto.
- thread set 222 is intentionally obstructed (e.g., fouled, welded, capped, etc.) after anchor 208 is threaded onto shaft 202 to prevent anchor 208 from being removed.
- thread set 222 may be left intact to allow anchor 208 to be removed and replaced.
- Intermediate section 220 is smooth to facilitate the sliding of engaging member thereon.
- the size of push member 200 is substantially larger than the diameter of shaft 202 .
- the larger size of push member 200 disperses the force exerted against a user's hand, when the user pushes against push member 200 .
- the larger size of push member allows push member 200 to serve as a more comfortable handle for fastener 100 .
- Having outer diameter of shaft 202 that is less than one-half of the outer diameter of push member 200 would make push member 200 more comfortable to push on.
- the diameter of shaft 202 is approximately 20 percent of the diameter of push member 200 .
- push member 200 is roughly a circular cylinder in this example embodiment, alternate push members/handles of any size or shape sufficient to disperse applied forces can be used.
- Engaging member 204 includes a first side 224 , a second side 226 , and an aperture 228 passing therebetween.
- First side 224 includes biasing member seat 230 onto which biasing member 206 is seated and centered with respect to aperture 228 .
- Second side 226 is configured (e.g., smooth and flat in this example embodiment) to urge against wall 104 .
- Aperture 228 is configured to receive intermediate section 220 of shaft 202 such that engaging member 204 can slide along intermediate section 220 .
- Biasing member 206 is a coil spring configured to urge engaging member 204 toward anchor 208 along shaft 202 . As shown, biasing member 206 includes a first end 232 and an opposite second end 234 seated on seats 214 and 230 , respectively.
- Anchor 208 is fixed near an end of shaft 202 opposite push member 200 .
- anchor 208 is a toggle anchor, which has a natural tendency to deploy as shown in FIG. 2 .
- anchor 208 is configured to operate in either a first state or a second state. In the first state, anchor 208 is in a loaded position (shown in FIG. 4 ), where it is able to pass through openings 106 and 108 . In the second state (shown in FIG. 2 ) anchor 208 is in a deployed position where it cannot be retracted through openings 106 and 108 , but instead securely engages feeder 102 .
- Anchor 208 includes a pair of wings 236 pivotally coupled to a threaded coupler 238 , which engages thread set 222 .
- wings 236 can be pivotally coupled to an alternative coupler that is rigidly fixed to shaft 202 .
- Each of wings 236 is in contact with a torsion spring ( FIG. 3 B ), which tends to force wings 236 apart.
- wings 236 pivot towards one another (against the force of the torsion spring) to minimize the cross-sectional area of anchor 208 .
- the torsion spring forces wings 236 apart, making the cross sectional area of anchor 208 too large to fit back through the hole without an intervening agent (e.g. a user) forcing wings 236 together.
- Fastener 100 is configured to secure feeder 102 to wall 104 by simultaneously urging engaging member 204 against wall 104 while pulling feeder 102 toward wall 104 .
- feeder 102 and wall 104 are sandwiched between engaging member 204 and anchor 208 via spring force exerted thereon from biasing member 206 .
- Anchor 208 is on the opposite side of openings 106 and 108 of feeder 102 and wall 104 , respectively, from engaging member 204 .
- the force provided by biasing member 206 biases engaging member 204 and anchor 208 toward one another and against surfaces of wall 104 and feeder 102 , respectively.
- Biasing member 206 forces engaging member 204 away from push member 200 .
- biasing member 206 also forces engaging member 204 toward anchor 208 .
- the combination of biasing member 206 and push member 200 creates a squeezing force between engaging member 204 and anchor 208 .
- This squeezing force holds feeder 102 against wall 104 .
- feeder 102 may be too heavy, in which case, shaft 202 can rest on a bottom edge 240 of opening 108 , holding feeder 102 in place.

Description
- This application is a continuation of co-pending U.S. patent application Ser. No. 17/114,439, filed Dec. 7, 2020 by the same inventor, which is a continuation of U.S. patent application Ser. No. 15/785,994, filed Oct. 17, 2017 by the same inventor, which claims the benefit of priority to U.S. Provisional Patent Application Ser. No. 62/409,958, filed Oct. 19, 2016 by the same inventor, each of which is incorporated herein by reference in its entirety.
- This invention relates generally to securing devices, and more particularly to devices used to secure multiple objects together. Even more particularly, the invention relates to securing objects together in pet/livestock environments.
- In the swine industry creep feeders are used to feed piglets in a farrowing crate. It is desirable that the creep feeders are attached to a wall, fence, or other border of the farrowing crate. Farmers usually care for many piglets, so it is desirable that a device used for attaching a creep feeder to a farrowing crate is simple, easy and quick to use. Typically piglets are rough on objects in the farrowing crate, so it is desirable that the device is durable. Farmers also need creep feeders to stay in place, so it is desirable that the device is dependable. Additionally, agricultural environments are often dirty. Therefore, it is desirable that a device for attaching a creep feeder is easy to wash and disinfect. What is needed, therefore, is a device for securing an object to another object (e.g. a wall) that is easy and quick to operate, durable, dependable, and easy to wash and disinfect.
- Various aspects of the present invention overcome problems associated with the prior art by providing a fastener for securing an object (e.g., a feeding dish) to another object (e.g. a wall) that is easy and quick to operate, durable, dependable, and easy to wash and disinfect.
- Example fasteners for securing a first object to a second object are disclosed. One example fastener includes a push member, a rigid shaft, an engaging member, a biasing member, and an anchor. The push member has a first side and an opposite second side. The first side includes a surface configured to disperse force exerted thereon by a user. The rigid shaft has a first end and a second end. The first end of the rigid shaft is coupled to the second side of the push member. The engaging member is coupled to slide along the shaft, defines an aperture and includes a first side and an opposite second side. The rigid shaft extends through the aperture, and the second side of the engaging member is configured to abut a surface of the first object. The biasing member is disposed between the push member and the engaging member. The biasing member urges the engaging member along the rigid shaft in a direction away from the push member. The anchor is coupled to the second end of the rigid shaft. The anchor is also configured to pass through an opening in the first object and an opening in the second object when the anchor is in a first state. The anchor is additionally configured to prevent passage of the anchor through the opening in the first object and the opening in the second object when the anchor is in a second state. The anchor is transitionable between the second state and the first state by the user to facilitate the withdrawal of the anchor through the opening in the first object and the opening in the second object. In a particular example fastener, the outer diameter of the rigid shaft is less than half the outer diameter of the push member. Optionally, the push member includes an ellipsoidal surface. An example fastener further includes instructions for using the fastener to secure the first object to the second object between the anchor and the engaging member.

The engaging member further includes a first side and an opposite second side, which is configured to abut a surface of the object. The rigid shaft extends through the aperture, and the biasing member is disposed between the first end of the rigid shaft and the engaging member. The biasing member urges the engaging member along the rigid shaft in a direction away from the first end of the rigid shaft. The anchor is coupled to the second end of the rigid shaft. The anchor is configured to pass through an opening in the object and the opening in the container when the anchor is in a first state, and to prevent passage of the anchor through the opening in the container and the opening in the object when the anchor is in a second state.

FIG. 1 is a perspective view of afastener 100 shown securing afeeder 102 to awall 104 according to one example embodiment of the present invention.Feeder 102 includes anopening 106 that is aligned with another opening 108 (shown inFIG. 2 ) formed inwall 104. Whenfeeder 102 is secured to wall 104,fastener 100 is simultaneously disposed through bothopenings feeder 102 is shown as being a creep feeder. However,feeder 102 represents any type of container (e.g., food dish, water dish, parts container, etc.) that would be desirable to removably attach to an object. Likewise,wall 104 represents any type of object (e.g., wall, cage, fence, pen, etc.) onto which it would be desirable to removably attach a container or other object. In the case of a pen,fastener 100 would pass from outside of the pen, between the bars of the pen, and throughopening 106. - In the example embodiment,
fastener 100 is provided in combination withinstructions 110 for usingfastener 100 to secure two objects together (e.g., securingfeeder 102 to wall 104 via fastener 100). -
FIG. 2 is a side view offastener 100 securingfeeder 102 towall 104.Fastener 100 includes apush member 200, arigid shaft 202, an engagingmember 204, a biasingmember 206, and ananchor 208.Push member 200 andanchor 208 are coupled to opposite ends ofrigid shaft 202. Engagingmember 204 is slidably disposed onrigid shaft 202 betweenpush member 200 andanchor 208. Biasing member is disposed betweenpush member 200 and engagingmember 204. -
Push member 200 includes afirst side 210 and an oppositesecond side 212.First side 210 provides a relatively large flat surface configured to comfortably disperse force exerted thereon by a user's hand whenpush member 200 is urged against.Second side 212 includes aseat 214 onto which biasingmember 206 is stabilized and centered with respect torigid shaft 202, which passes therethrough. - In the example embodiment,
rigid shaft 202 is a bolt having afirst end 216, an oppositesecond end 218, and anintermediate section 220 disposed therebetween.First end 216 is a bolt head that is fixed to pushmember 200.Second end 218 includes athread set 222 that facilitates the coupling ofanchor 208 thereto. In this example, thread set 222 is intentionally obstructed (e.g., fouled, welded, capped, etc.) afteranchor 208 is threaded ontoshaft 202 to preventanchor 208 from being removed. Optionally, thread set 222 may be left intact to allowanchor 208 to be removed and replaced.Intermediate section 220 is smooth to facilitate the sliding of engaging member thereon. - As shown, the size of
push member 200 is substantially larger than the diameter ofshaft 202. The larger size ofpush member 200 disperses the force exerted against a user's hand, when the user pushes againstpush member 200. The larger size of push member allowspush member 200 to serve as a more comfortable handle forfastener 100. Having outer diameter ofshaft 202 that is less than one-half of the outer diameter ofpush member 200 would makepush member 200 more comfortable to push on. In the example embodiment, the diameter ofshaft 202 is approximately 20 percent of the diameter ofpush member 200. Furthermore, althoughpush member 200 is roughly a circular cylinder in this example embodiment, alternate push members/handles of any size or shape sufficient to disperse applied forces can be used. - Engaging
member 204 includes afirst side 224, asecond side 226, and anaperture 228 passing therebetween.First side 224 includes biasingmember seat 230 onto which biasingmember 206 is seated and centered with respect toaperture 228.Second side 226 is configured (e.g., smooth and flat in this example embodiment) to urge againstwall 104.Aperture 228 is configured to receiveintermediate section 220 ofshaft 202 such that engagingmember 204 can slide alongintermediate section 220. -
Biasing member 206 is a coil spring configured to urge engagingmember 204 towardanchor 208 alongshaft 202. As shown, biasingmember 206 includes afirst end 232 and an oppositesecond end 234 seated onseats -
Anchor 208 is fixed near an end ofshaft 202opposite push member 200. In this example embodiment,anchor 208 is a toggle anchor, which has a natural tendency to deploy as shown inFIG. 2 . More specifically,anchor 208 is configured to operate in either a first state or a second state. In the first state,anchor 208 is in a loaded position (shown inFIG. 4 ), where it is able to pass throughopenings FIG. 2 )anchor 208 is in a deployed position where it cannot be retracted throughopenings feeder 102.Anchor 208 includes a pair ofwings 236 pivotally coupled to a threadedcoupler 238, which engagesthread set 222. Optionally,wings 236 can be pivotally coupled to an alternative coupler that is rigidly fixed toshaft 202. Each ofwings 236 is in contact with a torsion spring (FIG. 3B ), which tends to forcewings 236 apart. Whenanchor 208 is forced through a hole,wings 236 pivot towards one another (against the force of the torsion spring) to minimize the cross-sectional area ofanchor 208. Whenanchor 208 clears the hole (i.e.openings 106 and 108), the torsionspring forces wings 236 apart, making the cross sectional area ofanchor 208 too large to fit back through the hole without an intervening agent (e.g. a user) forcingwings 236 together. -
Fastener 100 is configured to securefeeder 102 to wall 104 by simultaneously urging engagingmember 204 againstwall 104 while pullingfeeder 102 towardwall 104. In other words,feeder 102 andwall 104 are sandwiched between engagingmember 204 andanchor 208 via spring force exerted thereon from biasingmember 206.Anchor 208 is on the opposite side ofopenings feeder 102 andwall 104, respectively, from engagingmember 204. The force provided by biasingmember 206biases engaging member 204 andanchor 208 toward one another and against surfaces ofwall 104 andfeeder 102, respectively.Biasing member 206forces engaging member 204 away frompush member 200. Becauseanchor 208 is disposed on the opposite end of biasingmember 206 frompush member 200, biasingmember 206 alsoforces engaging member 204 towardanchor 208. The combination of biasingmember 206 and pushmember 200 creates a squeezing force between engagingmember 204 andanchor 208. This squeezing force holdsfeeder 102 againstwall 104. In some cases, the biasing force provided by biasingmember 206, and resulting frictional forces between engagingmember 204,wall 104,feeder 102, andanchor 208, will be sufficient to holdfeeder 102 in place. In other cases,feeder 102 may be too heavy, in which case,shaft 202 can rest on abottom edge 240 ofopening 108, holdingfeeder 102 in place. - In the example
embodiment biasing member 206 is a compression spring with a relatively high spring constant. This particular element, as well as other described elements, is not an essential element of the present invention. For example, biasingmember 206 can be replaced by another type of biasing member coupled between engagingmember 204 and pushmember 200 or between engagingmember 204 andanchor 208. Additionally,coupler 238 is screwed onto the end ofshaft 202, which is fouled 242 to preventcoupler 238 from disengagingshaft 202. In alternate embodiments,coupler 238 can be integral or permanently fixed toshaft 202.Shaft 202 can also be replaced by another rigid member, with different characteristics thanshaft 202. The length of theshaft 202 can be altered to achieve the desired amount of travel ofanchor 208. These and other deviations from the particular embodiments shown will be apparent to those skilled in the art, particularly in view of the present disclosure. -
FIG. 3A is a sideview showing fastener 100. Becauseanchor 208 and pushmember 200 are not separated by a wall, biasingmember 206 is in a more relaxed state and urgesanchor 208 directly against engagingmember 204. Additionally,anchor 208 is visible from a different angle, showingwings 236 and a lower edge ofcoupler 238.Extensions 300 ofcoupler 238 are also shown engagingwings 236. -
FIG. 3B is a sectional view, taken along line A-A ofFIG. 3A , showingfastener 100, includinganchor 208 in greater detail.Anchor 208 includeswings 236, which each have a horseshoe-shaped cross section along their width.Wings 236 are held apart by atorsional spring 302, which includes a winding 304 and a pair oflegs 306, which extend toward the distal ends of each ofwings 236. Winding 304 stores the torsional energy ofspring 302.Legs 306 apply the restoring force ofspring 302 to thewings 236 forcing them open, unless impeded by another force. Additionally, winding 304 is disposedadjacent coupler 238 and betweenwings 236 andshaft 202.Coupler 238 includes a threadedaperture 308, which is complementary to thread set 222 ofshaft 202 and engagescoupler 238 toshaft 202. -
FIG. 4 is a sideview showing fastener 100, includinganchor 208 in a first state, whereinanchor 208 is in a retracted, loaded configuration.Wings 236 are folded inward, against the force of torsional spring 302 (FIG. 3B ). The distal ends ofwings 236 are held in place by a securing feature which, in this example, includes the sidewall of acircular recess 400 formed in thesecond side 226 engagingmember 204. Whenfastener 100 is pushed through anopening 402 in awall 404,anchor 208, in the retracted loaded configuration, passes easily through. However, engagingmember 204 cannot pass throughopening 402. So, a continued force onfastener 100pushes engaging member 204 towardpush member 200 andcompresses biasing member 206. Continued movement ofwings 236 throughopening 402 in combination with the stoppage of engagingmember 204 bywall 404, causes the ends ofwings 236 to disengagecircular recess 400. Then, whenwings 236 are pushed completely throughopening 402,wings 236 will open under the force oftorsional spring 302. Whenwings 236 are open,anchor 208 is too large to fit back throughopening 402. Thus,fastener 100 is in the second (deployed) state, where it is locked in place by releasing the force applied to pushmember 200. -
FIG. 5A is a perspective view of the front side of engagingmember 204. Engagingmember 204 is a circular plate formed, for example, from plastic. Engagingmember 204 includesaperture 228 andcircular recess 400.FIG. 5B is a perspective view of the back side of engagingmember 204. Engagingmember 204 includes biasingmember seat 230 configured to engage biasing member 206 (FIG. 2 ). -
FIG. 5C is a perspective view of the front side ofpush member 200.Push member 200 is a circular plate formed, for example, from plastic.Push member 200 includes anaperture 500 and biasingmember seat 214 adapted to engage biasing member 206 (FIG. 2 ).FIG. 5D is a perspective view of the first (rear)side 210 ofpush member 200.First side 210 ofpush member 200 includes a hex-shapedrecess 502 adapted to receive the hex head of shaft 202 (FIG. 1 ). - In the example embodiment, engaging
member 204 and pushmember 200 are formed from black plastic. In alternate embodiments, engagingmember 204 and pushmember 200 can be painted or otherwise decorated to personalize them for individual users. Additionally, engagingmember 204 and pushmember 200 can be formed from other materials, including, but not limited to, stainless steel, aluminum, or other metals. Biasing member seats 214 and 230 can also be replaced by a circular channel or omitted entirely. As another option,push member 200 can be formed integrally onfirst end 216 of shaft 202 (FIG. 2 ). -
FIG. 6A is a side view showing an alternate engagingmember 600. Engagingmember 600 includes a biasingmember seat 602 for engaging a biasing member. Engagingmember 600 also includesprotrusions 604, which create atextured surface 606.Textured surface 606 more effectively engages other textured surfaces, such as a wire fence, bars of a pen, and so on.FIG. 6B is a front view of alternate engagingmember 600, showing the arrangement ofprotrusions 604 ontextured surface 606 in greater detail.Protrusions 604 are arranged in a square, which has a common center with the center of engagingmember 600. Additionally, engagingmember 600 includes acircular recess 608 for engaging an expandable anchor, such asanchor 208. -
FIG. 7 shows a side view of analternate fastener 700 in a loaded state.Fastener 700 is substantially similar tofastener 100 and, therefore, like elements are denoted with like reference numbers and are not described again to avoid redundancy. -
Fastener 700 includes apush member 702, arigid shaft 704, an engagingmember 706, biasingmember 206, andanchor 208.Push member 702 andanchor 208 are coupled to opposite ends ofrigid shaft 704. Engagingmember 706 is slidably disposed onrigid shaft 704 betweenpush member 702 andanchor 208.Biasing member 206 is disposed betweenpush member 702 and engagingmember 706. - In this particular embodiment,
push member 702 is an ellipsoid (e.g., spherical) having afirst end 708 and asecond end 710.First end 708 is rounded to comfortably engage the palm of a user's hand to disperse force exerted thereon whenpush member 702 is urged against.Second end 710 includes a biasingmember seat 712 onto which biasingmember 206 is stabilized and centered with respect torigid shaft 704. -
Rigid shaft 704 includes afirst end 714, asecond end 716, and anintermediate section 718 disposed therebetween.First end 714 is fixed to pushmember 702 by some suitable means such as, for example, adhesive, threads, etc.Second end 716 includes athread set 720 onto which anchor 208 is threaded.Intermediate section 718 is smooth to facilitate the sliding of engagingmember 706 thereon. - Engaging
member 706 includes afirst side 722, asecond side 724, and anaperture 726 passing therebetween.First side 722 includes a biasingmember seat 728 onto which biasingmember 206 is seated and centered with respect toaperture 726.Second side 724 further includes a set ofpull members 730, which facilitatecompressing biasing member 206 with a single hand. To compress biasingmember 206, a user first engagestension members 730 with their fingers and pushmember 702 with their palm. Then, the user squeezes, thereby urging engagingmember 706 towardpush member 702, against the opposing force of biasingmember 206. This feature is particularly useful in releasingfastener 700 from an opening in an object, because it releases the pressure betweenanchor 208 and whatever is being secured to the object such as, for example,feeder 102. Once the pressure is released, the user can urgeanchor 208 back into a collapsed position with their free hand so that it can be backed out of the opening in which it was disposed.Second side 724 is configured to urge against a wall, cage bars, pen, etc. In this example,second side 724 includes an array ofprotrusions 732 and arecess 734.Protrusions 732 effectively engage textured surfaces such as, for example, cage bars, textured walls, etc. Of course, the spring force can be selected so thatsecond side 724 can also effectively engage smooth surfaces.Recess 734 is identical to recess 400 in functionality and is, therefore, not described again.Aperture 726 is configured to receive smoothintermediate section 718 ofshaft 704, so that engagingmember 706 can slide alongintermediate section 718. -
FIG. 8 shows a side view of anotheralternate fastener 800.Fastener 800 is substantially similar tofastener 700. Therefore, like elements are denoted with like reference numbers and will not be described in detail again to avoid redundancy. The main difference betweenfastener 800 andfastener 700 is thatanchor 208 offastener 700 has been replaced with ananchor 802 and engagingmember 706 has been replaced with engagingmember 804. -
Anchor 802 is a 180 degree bend insecond end 716 ofrigid shaft 704 to form a J-hook.Anchor 802 is configured to be inserted into an elongated opening formed in an object (e.g., feeder, storage dish, etc.). Once inserted through the elongated opening,push member 702 is rotated 90 degrees such that it is misaligned with the opening and, therefore, cannot be removed from the opening unlesspush member 702 is rotated back 90 degrees. In a scenario in which the opening in the object to be secured is not elongated, the object may include a recess to seat the open end ofanchor 802.Anchor 802 can be inserted through a round opening and then moved to the side of the opening so that the J-hook can engage the edge of the opening.Anchor 802 can also effectively secure non-planar objects. For example,fastener 800 can be used to secure the wire handle of a bucket to a fence. - Engaging
member 804 is substantially identical to engagingmember 706 but does not includerecess 734 andtensions members 730. -
FIG. 9 is a side view of analternate fastener 900.Fastener 900 is substantially similar tofastener 800. Therefore, like elements are denoted with like reference numbers and are not described again to avoid redundancy. The main difference betweenfastener 900 andfastener 800 is thatanchor 802 offastener 800 has been replaced with analternate anchor 902. -
Anchor 902 includes a cross-member 904 rigidly attached tosecond end 716 ofrigid shaft 704 to form a T-member.Anchor 902 is configured to be inserted into an elongated opening (e.g., a slot) formed in an object (e.g., feeder, storage dish, etc.). Once inserted through the elongated opening in an aligned first state,push member 702 is rotated such that it is misaligned with the opening (i.e., transitioned into a second state) and, therefore, cannot be removed from the opening unlesspush member 702 is rotated back and realigned with the opening (first state). -
FIG. 10 shows a side view of analternate fastener 1000.Fastener 1000 is substantially similar tofastener 700. Therefore, like elements are denoted with like reference numbers and are not described in detail again to avoid redundancy. The main difference betweenfastener 1000 andfastener 700 is that engagingmember 706 offastener 700 has been replaced with an alternate engagingmember 1002. - Engaging
member 1002 includes afirst side 1004, asecond side 1006, and anaperture 1008 passing therebetween.First side 1004 includes biasingmember seat 1010 onto which biasingmember 206 is seated and centered with respect toaperture 1008.Second side 1006 includes a plurality of substantiallyparallel ridges 1012 configured to engage bars of, for example, a cage or the like.Ridges 1012 provide significant friction between engagingmember 1002 and bars because of the increased contact surface area therebetween. That is,ridges 1012 protrude into the space between bars so as to engage more area of the outer surface of the bars as compared to a generally planar engaging member. In addition,parallel ridges 1012 positively engage bars (or other substantially parallel structures) to prevent rotation of engagingmember 1002 with respect to the bars.Second side 1006 further includes arecess 1014 that functions identical to recess 734 of engagingmember 706 by securinganchor 208 in a loaded position.Aperture 1008 is configured to slide alongintermediate section 718 ofshaft 704. -
FIG. 11 is a perspective top view of engagingmember 1002 shown removed fromfastener 1000. As shown, engagingmember 1002 has a rectangular outer perimeter to increase surface area contact with bars. Optionally,ridges 1012 can have a rectangular cross-section, as opposed to the triangular cross-section shown inFIG. 11 , to provide even stronger engagement with bars disposed in channels between the ridges. -
FIG. 12 is a perspective top view of an alternate engagingmember 1200. Engagingmember 1200 is substantially similar to engagingmember 1002 but includes an array ofprotrusions 1202, rather thanridges 1012. Likeprotrusions 604 of engagingmember 600,protrusions 1202 effectively engage other textured surfaces, such as wire fences, bars of a pen, and so on. -
FIG. 13 is a side view of analternate fastener 1300 further including analternate pull member 1301. In the example embodiment,pull member 1301 is a U-shaped structure, slidably disposed through a set ofapertures 1302 formed inpush member 200 and fixably attached to engagingmember 204. For example, each side ofpull member 1301 passes through engagingmember 204 and includesbends 1304 so as to not be pulled through whenpull member 1301 is pulled towardpush member 200. Optionally, bends 1304 can be eliminated by securing the ends ofpull member 1301 within, or to the rear surface, of engagingmember 204.Pull member 1300 facilitates the compression of biasingmember 206 by providing a structure to pull engagingmember 204 towardpush member 200. Doing so releases the pressure betweenanchor 208 and engaging member 204 (or some other engaged object), allowing the user to collapse a deployedanchor 208. -
FIG. 14 is a flowchart summarizing amethod 1400 of manufacturing a fastener. In afirst step 1402, a push member is provided. Then, in asecond step 1404, a rigid shaft is provided. Next, in athird step 1406, a biasing member is provided. Then, in afourth step 1408, an engaging member is provided. Next, in afifth step 1410, an anchor is provided. Then, in asixth step 1412, the rigid shaft is coupled the push member. Next, in aseventh step 1414, the rigid shaft is coupled to the engaging member. Then, in aneighth step 1416, the biasing member is positioned between the push member and the engaging member. Finally, in aninth step 1418, the anchor is coupled to the rigid shaft. The specific order of the steps can be altered, depending on the specific configuration of each component part. -
FIG. 15 is a flowchart summarizing amethod 1500 of using a fastener. In afirst step 1502, a first object is provided. Then, in asecond step 1504, a second object is provided. Next, in athird step 1506, a fastener is provided. Then, in athird step 1508, the first object is positioned with respect to the second object. Next, in afourth step 1510, the fastener is inserted through an opening in the first object and an opening in the second object. Then, in afifth step 1512, the fastener is transitioned from a first state to a second state, to secure the first object to the second object. Next, in aseventh step 1514, the fastener is transitioned from the second state back to the first state. Then, in aneighth step 1516, the fastener is withdrawn from the opening in the first object and the opening in the second object, to detach the first object from the second object. Instructions that teach or suggest to a user how to fasten one object to another (e.g., performmethod 1500 or similar method) can be provided with any fastener disclosed herein. - Various embodiments of the fastener disclosed herein provide important advantages over devices of the prior art. For example, the use of the device can be accomplished primarily from the outside of a farrowing crate (or other enclosure or structure), making it easy to use. In addition, the portion of the device that creates the biasing force is located outside of the farrowing crate, keeping it safely away from the livestock inside the farrowing crate. Yet another advantage is that the portion of the securement device positioned inside the farrowing crate (i.e., anchor 208) provides a means for quick release of
feeder 102 from thefastener 100 and a quick release offastener 100 fromwall 104. - The description of particular embodiments of the present invention is now complete. Many of the described features may be substituted, altered or omitted without departing from the scope of the invention. For example, alternate shafts (e.g., a completely smooth rod), may be substituted for the bolt of
fastener 100. As another example, fasteners described herein can be used to attach different items together (e.g., bins/containers for supplies/parts in a contractor's van) This and other deviations from the particular embodiments shown will be apparent to those skilled in the art, particularly in view of the foregoing disclosure.
