Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This invention claims priority under 35 U.S.C. § 120, to the U.S. Non-Provisional Pat. Application No. 16/455,487, to Linda Kay Parker, filed on Jun. 27, 2019, which is incorporated by reference herein in their entireties.

FIELD OF THE INVENTION

The present invention relates to latches, specifically to latch assemblies for latching parts of objects together.

DESCRIPTION OF THE RELATED ART

In the related art, it has been known to use latches to secure items such as purses, satchels, handbags, briefcases, luggage, backpacks, diaries, tool boxes, etc. Mechanical latches represent a method of releasably engaging and holding or otherwise joining or assembling objects such as panels, enclosures, belts, fabric, or other similar, discreet objects. A wide variety of special-purpose fasteners are currently employed in the industry for quick-operating, repeated access applications.
Specifically, push button operated latches and locks are well known. The contents of objects are typically secured from intrusion and unwanted inspection by the use of push button latches. It has been the usual practice for many years in the design and construction of combined latch and lock mechanisms for luggage cases and the like to provide a spring biased bolt on one of the separable container sections which is urged into latching relation with a keeper on the other separable case section.
Push button latches can be attached to objects or incorporated in a variety of ways. Some improvements have been made in the field. Examples of references related to the present invention are described below in their own words, and the supporting teachings of each reference are incorporated by reference herein:
U.S. Pat. No.: 3.605,210, issued to Lohr, discloses a safety seat belt buckle having a pair of locking members which engage opposite side edges of a plate-like tongue to prevent its removal from a latched position in the buckle. A release member on the buckle is connected to the locking members such that they can be moved toward release positions either by a motion of the release member, or by contact with the tongue as it is received toward its latched position.
U.S. Pat. No.: 4,321,734, issued to Gandelman, discloses a clasp assembly is provided for securing together the free ends of opposed flexible members and includes a first coupling member that is joined to the free end of one of the flexible members and a second coupling member that is joined to the free end of the other flexible member. In the latched position the coupling members appear to be an integral part of the flexible members and impart an ornamental appearance thereto. The first coupling member includes a box element in which a transversely extending spring is located and has a pair of snap levers pivotally mounted on the sides thereof. The second coupling member includes an outwardly extending tongue element that is formed with opposed notches that are engageable with the snap levers for locating the tongue in a latched position within the first coupling member, the snap levers being pivotally movable relative to the tongue and against the action of the spring from a closed to an open position upon the application of a force thereto, for releasing the tongue from engagement with the snap levers and thereby disengaging the coupling members.
U.S. Pat. No.: 4,792,165, issued to Nishimura, discloses a plush latch device composed of a case and a slider which slides into the case and out therefrom. The movement of the slider is controlled by a guide mechanism disposed between the slider and the case. The guide mechanism consists of an annular guide passageway formed in a cone side inner surface of the case and a guide lever having a guide member which moves along the guide passageway while being pressed against the side wall thereof. The guide passageway is formed with a substantially V-shaped stoppage portion for stopping the slider within the case. The guide lever has a support spindle formed with a flat surface having an angle to the longitudinal direction of the guide lever to impart forces for pressing the side wall of the guide passageway, the guide lever rotating about the support spindle. The rotary moment is imparted to the guide lever by pushing the support spindle by a coil spring for moving the slider.
U.S. Pat. No.: 5,217,262, issued to Kurosaki, discloses a latch device including a pair of circuital cam grooves having different planar shapes formed in opposite surfaces of a latch body. A guide lever is inserted into the circuital cam grooves so that tips of tracing portions of the guide lever do not contact bottom surfaces of the circuital cam grooves. The circuital cam grooves have a heart-shaped projection and a triangular projection, such that torsion is generated in the tracing portions because of differences in configuration of the circuital cam grooves. A restoring force of the guide lever acting opposite the torsional force causes the tracing portions to circulate in a given direction. As a result, compared with conventional latch devices, fewer components may be used. Wear on the circuital grooves of the latch body can be prevented. When the torsional force is eliminated, the tracing portions move in a direction where the groove wall surfaces are not provided. No unpleasant impact sound (operating sound) is produced because the tracing portions do not strike against the groove wall surfaces.
U.S. Pat. No.: 5.273,328, issued to Kurosaki, discloses a lock mechanism for causing an openable member such as a cover or a door of a box or the like to engage with or disengage from a main body as the openable member is pressed, and a latch device for retaining a latch body in the housing in a state in a pushed-in state and in a withdrawn state. The center of rotation of each of a pair of arms of the latch device is formed on substantially the same line as a line of action of a force acting on a retaining surface of each of the arms for retaining a striker. A fitting hole, a guide hole, a slanted guide surface, and a fitting hole are provided to allow a tracing member of the latch device to be fitted from outside the housing at the time of assembling the tracing member to the housing. In the lock mechanism and the latch device, the tracing member is caused to trace side walls of a pair of circulatory guide paths by making use of the resilient restoring force of a resilient tracing member, and the tracing member is maintained in a state of noncontact with the bottom surfaces of the circulatory guide paths during tracing.
The inventions heretofore known suffer from a number of disadvantages which include not being easily scalable to different sizes, having less consistent manufacturing, being difficult to latch, having less control over release, having the ability to be accidentally released, being difficult to manufacture, being difficult to use, being unreliable, being more likely to get stuck, and being weaker.
What is needed is a latch assembly that solves one or more of the problems described herein and/or one or more problems that may come to the attention of one skilled in the art upon becoming familiar with this specification.

FIG. 1 illustrates a right side perspective view of a latch assembly 10, according to one embodiment of the invention. There is shown a latch assembly 10 with a latch buckle 12, and a latch tongue 14 removably coupled to the latch buckle 12. The latch buckle 12 includes a buckle housing 13 and h-shaped levers 16 protruding through the buckle housing 13. The latch tongue 14 includes a latch flange 18 for removably coupling the latch tongue 14 to the latch buckle 12.
The illustrated latch buckle 12 includes a buckle housing 13. As shown, the buckle housing 13 may substantially contain (or house) components of the latch buckle 12, such as, but not limited to, the levers 16. The buckle housing 13 may have any size and/or shape for housing components of the latch buckle 12 and/or removably coupling to the latch tongue 14, such as, but not limited to: square, rectangular, elongated, ovoid, round, and so on. Further, the buckle housing 13 may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers and/or glass.
As shown, the levers 16 may be substantially disposed within the buckle housing 13. Also shown, the 16 levers may protrude from the buckle housing 13 so that the levers 16 may function as push-buttons for releasing the latch flange 18 for uncoupling the latch tongue 14 from the latch buckle 12. The levers 16 may have any size and/or shape for removably coupling to the latch flange 18 of the latch tongue 14 and for functioning as push-buttons. Likewise, the levers 16 may be comprised of a variety of materials for removably coupling to the latch flange 18, such as, but not limited to: metal, plastic, wood, rubber, polymers and/or glass.
The illustrated latch tongue 14 includes a latch flange 18. The latch flange 18 removably couples the latch tongue 14 to the buckle housing 13. The latch flange 18 may removably couple to the h-shaped levers 16. For instance, in one non-limiting embodiment, the latch flange 18 may removably couple to the levers 16 by tight-fitting, such as spring-fitting. Accordingly, the latch flange 18 may have any size or shape that compliments the size and/or shape of the levers 16 for removably coupling to the levers. For example, the latch flange 18 may be shaped, such as, but not limited to: T-shaped, mallet-shaped, club-shaped, fan-shaped, etc. Likewise, the latch flange 18 may be forked. Moreover, the latch flange 18 may be comprised of a variety of materials for complimenting the levers 16, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
In operation of one embodiment of the invention, there is a latch assembly 10 that includes a latch buckle 12 removably coupled to a latch tongue 14. The latch assembly may be a light-weight assembly. The latch buckle 12 includes levers 16 that are a dual release. A major portion of the levers 16 are disposed within an interior of a buckle housing 13 of the latch buckle 12. As a result, a portion of a latch flange 18 of the latch tongue 14 passes through the interior of the buckle housing 13 to couple to the levers 16 in an interior of the housing 13. The levers 16 function to release the latch flange 18 when simultaneously pressed, or pushed, and thereby not coming accidentally unlatched.
Advantageously, the illustrated latch assembly may be coupled to a pair of structures, wherein the buckle is coupled to one structure and the tongue is coupled to another structure and those structures may then be selectively mated together and selectably released from each other as desired by applying force to the ends of the lever arms that extend from the buckle housing. Further, the spacing and tolerances of the various components may be such that both lever arms must be pivoted in order to release the tongue from the buckle, thereby reducing the likelihood of accidental separation of the tongue from the buckle.
Such a latch assembly may be applied to a great variety of associated structures, including but not limited to purses, bags, luggage, clothing, wall mountings, decorative accessories, modular systems, electronics installations, tool belts, mounts for vehicle interiors, and the like and combinations thereof. The illustrated tongue and buckle may be affixed to such structures by various means, including but not limited to screws, rivets, pins, glue, contact adhesive, hook-and-loop, magnets, and the like and combinations thereof.
In one non-limiting embodiment, the buckle is disposed within a container (e.g. a purse) with a slit through an exterior wall of the container that matches up with the aperture of the buckle so that a tongue may enter thereinside and couple to the buckle from outside the container. There may be a plurality of tongues that each fit the buckle, with each tongue coupled to a secondary bag, decorative item, or the like such that the user may selectably couple a plurality of different items to their container. Advantageously, someone without access to an interior of the container would not be able to release the latch assembly as the ends of the lever arms would be within the container.
FIG. 2 illustrates a left side perspective view of a latch buckle 12, according to one embodiment of the invention. There is shown a latch buckle 12 with a buckle housing 13 and levers 16 substantially disposed within the buckle housing 13. The buckle housing 13 includes a first lateral aperture 21 disposed along a first side 22 of the buckle housing 13. The buckle housing 13 also includes a front base plate 25 with a back base plate 26 coupled to the front base plate 25. Disposed between the front base plate 25 and the back base plate 26 there is a buckle aperture 27.
The illustrated buckle housing 13 includes a first lateral aperture 21 disposed along a first side 22. As shown, the levers 16 may protrude from the lateral aperture 21. Accordingly, the lateral aperture 21 may have any size or shape to allow the levers 16 to extend from the buckle housing 13.
Also, the illustrated buckle housing 13 includes a front base plate 25 and a back base plate 26 coupled to the front base plate 25. The base plates 25 and 26 may be coupled by a variety of coupling mechanisms, such as, but not limited to: screws, nails, bolts, pegs, snap-fit, dowels, adhesives, etc. The front base plate 25 and the back base plate 26 may be sized and/or shaped to substantially contain the levers 16. Similarly, the front base plate 25 and the back base plate 26 may be sized and/or shaped to form apertures 21 and/or allow the levers 16 to protrude therefrom. The base plates 25 and 26 may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
Further illustrated, there is a buckle aperture 27 disposed between the front base plate 25 and the back base plate 26. As a result, the front base plate 25 and the back base plate 26 may be shaped and/or sized to provide a buckle aperture 27. The buckle aperture 27 may have any shape and/or size configured to receive the latch flange of the latch tongue (See e.g., FIG. 1 , items 18 and 14, respectively).
FIG. 3 illustrates a right side exploded perspective view of a latch buckle 12, according to one embodiment of the invention. As shown, the latch buckle 12 includes a buckle housing 13 with a pair of levers 16 substantially disposed therein. The latch buckle 12 has a first side 22 with a second side 32 disposed substantially opposite the first side 22. Also disposed within the buckle housing 13 there is shown a spring ring 34 and a pair of springs 36. Further, disposed along an interior 37 of the back base plate (See e.g., FIG. 2 , item 26), of the buckle housing 13 are a plurality of lever traps 38 and a base plate lip 39.
The illustrated levers 16 are h-shaped (chair-shaped) and are substantially disposed within the buckle housing 13 with just the tips extending outside thereof so that they may be manipulated by hand to pivot as desired. The illustrated levers are mirror images of each other and each include a lever arm with a securing pin at an end thereof opposite the end that extends outside the buckle housing. The illustrated levers include hooks that extend orthogonally from the lever arms near a midpoint thereof. The hooks each point inward and form the structure that secures the latch flange within the buckle when it is disposed therein. Further, pivoting the lever arm about the securing pin causes the hooks to change position. Pivoting one direction traps the latch flange and pivoting the opposite direction releases the latch flange. The illustrated springs 36 bias the lever arms such that the hooks are in a mode to trap the latch flange. Further, the hooks each include an angled tip that allows the latch flange to cause the lever arms to pivot as the latch flange is entering between the hooks and the springs then snap the hooks back into a trapping mode after the latch flange has fully entered the hooks. The illustrated levers pivot about points (at the securing pins) adjacent to the spring ring and are disposed on opposite sides thereof.
The h-shaped levers 16 may be rotatably coupled to the buckle housing 13 so that they may rotate about an axis and/or provide leverage. The h-shaped levers 16 may have any size and/or shape for receiving and/or coupling to the latch flange of the latch tongue (See e.g., FIG. 1 , items 18 and 14, respectively). For example, the h-shaped levers 16 may be shaped such as, but not limited to: h’s, chairs, y’s, 4’s, and so on. Further, the h-shaped levers 16 may be identical and/or mirror-images. The h-shaped levers 16 may protrude from the buckle housing 13 so that they may function as push-buttons for releasing the latch flange (See e.g., FIG. 1 , item 18). In addition, the h-shaped levers 16 may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
Additionally illustrated, disposed within the buckle housing 13 there is shown a spring ring 34 and a pair of springs 36. The spring ring 34 may provide a spring-back force to help the latch flange (See e.g., FIG. 1 , item 18) release from the h-shaped levers 16. The spring ring 34 provides a bias against the latch flange, essentially pushing the latch flange out of the buckle when the h-shaped levers release it. The illustrated spring ring 34 is a torus, but it may have any size and/or shape and/or be comprised of any material that provides the described bias force to facilitate release the latch flange (See e.g., FIG. 1 , item 18). In one non-limiting embodiment, the spring ring 34 may be comprised of rubber, plastic, composites thereof and/or other elastically deformable materials.
The pair of springs 36 is functionally coupled to the h-shaped levers 16, and thereby allows the h-shaped levers 16 to pivot and/or to function as push buttons. Thus, the pair of springs 36 may bias the h-shaped levers 16 in open and closed positions. Likewise, the pair of springs 36 may have any size and/or shape and/or be comprised of any material to allow the h-shaped levers 16 to pivot. In one non-limiting embodiment, the pair of springs 36 may be comprised of metal.
Further illustrated, disposed along an interior 37 of the back base plate (See e.g., FIG. 2 , item 26), of the buckle housing 13, there are are a plurality of lever traps 38. The lever traps 38 may be integral to the back base plate (See e.g., FIG. 2 , item 26) or may be extensions thereof. As a result, the lever traps 38 may be comprised of a variety of material, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass. As illustrated, the plurality of lever traps 38 are substantially L-shaped; however, the plurality of lever traps 38 may have any size and/or shape for trapping, securing, stabilizing, etc. the h-shaped levers 16, such as, but not limited to: c-shaped, v-shaped, u-shaped, and so on.
Also illustrated, the back base plate (See e.g. FIG. 2 , item 26) includes a base plate lip 39. The base plate lip 39 is disposed along a length of the back base plate (See e.g., FIG. 2 , item 26). The base plate lip 39 may be integral to the back base plate (See e.g., FIG. 2 , item 26). Accordingly, the base plate lip 39 may be an extension of the back base plate (See e.g., FIG. 2 , item 26) and may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass. The base plate lip 39 may provide spacing between the front base plate and the back base plate (See e.g., FIG. 2 , items 25 and 26, respectively) for housing components of the latch buckle (See e.g., FIG. 1 , item 12) within the buckle housing (See e.g., FIG. 1 , item 13). As a result, the base plate lip 39 may have any size, shape, length, etc. configured to provide spacing.
FIG. 4 illustrates a left side perspective view of a latch tongue 14, according to one embodiment of the invention. As shown, the latch tongue 14 includes a latch flange 18. Coupled to the latch flange 18 is a plate spacer 42, and coupled to the plate spacer is a tongue plate 40.
The illustrated latch flange 18 extends from the latch tongue 14 so that it may be received by the h-shaped levers (See e.g., FIG. 1 , item 16) of the buckle housing (See e.g., FIG. 1 , item 13). For instance, in one non-limiting embodiment, the latch flange 18 may slide into the buckle housing (See e.g., FIG. 1 , item 13). Accordingly, the latch flange 18 may have any size and/or shape for removably coupling to the latch buckle (See e.g., FIG. 1 , item 12). For example, the latch flange 18 may be shaped, such as, but not limited to: T-shaped, mallet-shaped, club-shaped, fan-shaped, etc. Similarly, the latch flange 18 may be planar and/or substantially flat. More, the latch flange 18 may be comprised of a variety of materials for complimenting the h-shaped levers 16, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
Also illustrated, the latch flange 18 is coupled to a plate spacer 42. The plate spacer 42 spaces the latch flange 18 from the tongue plate 40. Thus, the plate spacer 42 is coupled to, and disposed between, the latch flange 18 and the tongue plate 40. The plate spacer 42 may be sized and/or shaped to provide spacing. For example, the plate spacer 42 may have a variety of lengths, diameters, and/or shapes for spacing, such as, but not limited to: cubed, cylindrical, trapezoidal, and so on. The plate spacer 42 may be integral to the tongue plate 40 such that the plate spacer 42 is an extension of the tongue plate. As a result, the plate spacer 42 may also be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
Further, the illustrated tongue plate 40 is coupled to the plate spacer 42 at an end opposite the latch flange 18. The tongue plate 40 may extend from the plate spacer in a direction parallel to the latch flange 18. The tongue plate 40 may provide support, such as a base, for the plate spacer 42 and the latch flange 18. Accordingly, the tongue plate may have any shape and/or size for providing support. The tongue plate 40 may be planar and/or substantially flat. The tongue plate 40 may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass. In one non-limiting embodiment, two or more of the tongue plate 40, plate spacer 42, and latch flange 18 may be a single component (e.g. molded as a single shaped piece) instead of a plurality of components coupled to each other.
FIG. 5 illustrates a right side exploded view of a latch tongue 14, according to one embodiment of the invention. As shown, the latch tongue 14 includes a latch flange 18. Coupled to the latch flange 18 is a plate spacer 42, and coupled to the plate spacer is a tongue plate 40.
The illustrated plate spacer 42 is disposed between the latch flange 18 and the tongue plate 40. The latch flange 18 and the tongue plate 40 may be coupled to the plate spacer 42 by a variety of coupling mechanisms, such as, but not limited to: screws, nails, bolts, pegs, dowels, adhesives, etc. Hence, the latch flange 18, the tongue plate 40. and the plate spacer 42, may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
FIG. 6 illustrates a back side perspective view of a latch assembly 10 with a cut-away of a front base plate 25, according to one embodiment of the invention. As shown, the latch assembly 10 includes a latch buckle 12 with a pair of h-shaped levers 16, and a latch tongue 14 with a latch flange 18. The latch assembly 10 also includes a second lateral aperture 61 disposed along a second side 32, a spring ring 34 disposed between a plurality of spring ring traps 62 and along the latch flange 18, and a pair of springs 36. The spring ring traps 62 are nubs extending into the space around the spring ring and prevent it from traveling within the buckle so that when the latch flange presses against the spring ring, the spring ring maintains its force/bias against the latch flange.
The illustrated latch assembly 10 includes a latch buckle 12 coupled to a latch tongue 14. The latch buckle 12 may be coupled to the latch tongue such as by push-button/spring release. For example, in one embodiment, the latch buckle 12 includes a pair of h-shaped levers 16 disposed within the latch buckle 12. Functionally coupled to the pair ofh-shaped levers 16 are a pair of springs 36 that may function to pivot the h-shaped levers and thereby release the latch tongue 14. The h-shaped levers 16 may protrude from the latch buckle 12. For instance, in one embodiment, the h-shaped lever 16 protrudes from a second lateral aperture 61 disposed along a second side 32 of the latch buckle. As a result, the second lateral aperture 61 may be shaped and/or sized to allow an h-shaped lever 16 to protrude from the latch buckle 12 and thereby function as a push-button release. In one non-limiting embodiment, both h-shaped levers 16 must be pushed simultaneously in order to release the latch tongue 14.
Also illustrated, the latch tongue 14 includes a latch flange 18. Disposed along the latch flange 18 is a spring ring 34. The spring ring 34 is disposed within the latch buckle 12. The spring ring 34 abuts the latch flange 18 and may flex so that it provides a force that assists in release of the latch flange 18 from the latch buckle 12 when the h-shaped levers 16 are pushed. Accordingly, an effective diameter of the spring ring 34 may increase or decrease when the latch flange presses against or releases from contact with the spring ring 34. For these reasons, the spring ring may be comprised of a flexible material, such as, but not limited to: rubber, plastic, polymers, etc. While the illustrated spring ring is circular, the spring ring may be of a different shape/configuration, so long as it operates to bias the tongue to exit the buckle, such as but not limited to a disc, oval, square, sphere, irregular shape, triangle, pyramid, and the like and combinations thereof.
Further illustrated, the spring ring 34 is disposed between a plurality of spring ring traps 62. The spring ring traps 62 may trap, secure, stabilize, hold in place etc. the spring ring 34. As a result, the spring ring traps 62 may be sized and/or shaped to trap the spring ring 34. For instance, the spring ring traps 62 may be shaped, such as, but not limited to: cones, pyramids, cylinders, cubes, and so on. The spring ring traps 62 are disposed within the latch buckle 12 and may be integral to the latch buckle 12. Hence, the spring ring traps 62 may be extensions of the latch buckle. Accordingly, the spring ring traps 62 may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
FIG. 7 illustrates a left side perspective view of a latch assembly 10, according to one embodiment of the invention. As shown, the latch assembly 10 includes an h-shaped lever 16 disposed between a front base plate 25 and a back base plate 26. The illustrated back base plate 26 includes a base plate lip 39. The latch assembly 10 also includes a latch flange 18 disposed within a buckle aperture 27 and removably coupled to the h-shaped levers 16. Coupled to the latch flange 18 is a plate spacer 42, and coupled to the plate spacer 42 is a tongue plate 40 so that the tongue plate 40 is disposed substantially below the back base plate 26. The latch assembly further includes a second lateral aperture 61.
The illustrated tongue plate 40 is disposed below the back base plate 26 along substantially the entire length of the back base plate 26. Accordingly, the tongue plate 40 provides additional support for the latch assembly 10. As a result, the tongue plate 40 may have any size, shape, length, diameter, etc. for supporting the latch assembly 10. Likewise, the tongue plate 40 may be comprised of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass.
It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
For example, although the figures illustrate a latch flange and h-shaped levers for latching, it is envisioned that any design of complimenting male and female components may be used for latching. Additionally, although the figures illustrate a single latch assembly, it is envisioned that objects may include multiple latch assemblies for latching. It is also envisioned that the latch assembly may be used for latching a plethora of objects, such as, but not limited to: purses, satchels, handbags, briefcases, luggage, backpacks, diaries, tool boxes, etc. More, the latch assembly may be sewn into the object into which it is being installed.
It is expected that there could be numerous variations of the design of this invention. An example is that the latch assembly may have multiple latch flanges or that the latch flanges may be forked. Likewise, although the figures illustrate a pair of h-shaped levers, the assembly may have any number of h-shaped levers.
Finally, it is envisioned that the components of the assembly may be constructed of a variety of materials, such as, but not limited to: metal, plastic, wood, rubber, polymers, and/or glass. The components of the assembly may be constructed by injection molding.
Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims. Further, it is contemplated that an embodiment may be limited to consist of or to consist essentially of one or more of the features, functions, structures, methods described herein.
