Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • [0001]
    This application is a continuation of co-pending U.S. application Ser. No. 10/836,058, filed Apr. 30, 2004, and entitled “Hinged Latch Device With Elongate Strap Hinge”, the disclosure of which is incorporated in its entirety.
  • BACKGROUND OF THE INVENTION
  • [0002]
    1. The Field of the Invention
  • [0003]
    The present invention relates to a latch device that may be used in a variety of areas, for example, tie downs for boats, campers, tarps, suit cases, back packs, and other sporting goods.
  • [0004]
    2. The Relevant Technology
  • [0005]
    Latch devices are used in a variety of areas to clamp or otherwise secure various articles. Existing devices can be rather complex, difficult to use, and often wear out prematurely. Because of these difficulties, there is a need for a simple, easy to use, durable latch device which can be used to secure a wide range of articles such as tie downs for boats, campers, tarps, suit cases, back packs, and other sporting goods.
  • [0006]
    It would be an improvement in the art to provide a latch device that is easy to open and close without use of any special tools or excessive force, that can be manufactured at low cost, and that exhibits high durability.
  • BRIEF SUMMARY OF THE PREFFERED EMBODIMENTS
  • [0007]
    The present invention is directed to a latch device that may be used in a variety of areas, including tie downs for boats, campers, tarps, suit cases, back packs, and other sporting goods.
  • [0008]
    The latch device includes a base that is suitable for attachment to a substrate, an elongate strap hinge, a cover that is attached to the base by the elongate strap hinge, a hinge guide structure on the base or a camming structure on an underside of the cover having a curved surface around which the strap bends when selectively moved to the closed position, and a locking mechanism to lock the cover in the closed position. The cover moves about the strap hinge between open and closed positions relative to the base. The camming structure, if present, helps to bias the cover toward the open position when not locked in the closed position.
  • [0009]
    The article to be held by the latch device is placed between the base and cover (i.e., in a slot formed within the base and/or cover) and then the cover is subsequently closed and locked to the base. The slot is advantageously spaced apart from the strap hinge so that the object held in the slot does not contact the strap hinge when the cover is in the closed position. This helps preserve the strength and integrity of the strap hinge against cutting or breaking forces that may result from the object held by the latch device.
  • [0010]
    Because the elongate strap hinge bends around the curved surface of the hinge guide structure and/or camming structure, the strap hinge is especially resistant to breakage. The curved surface prevents kinking and concentration of the stresses and forces associated with the operation of the hinge that might otherwise occur. Because the elongate strap hinge bends around the curved surface of the hinge guide structure and/or camming structure, the stresses and forces are distributed along a significant portion of the length of the strap hinge. According to one embodiment, the camming structure fits within and substantially fills a void space between the base and the elongate strap hinge when the cover is in the closed position.
  • [0011]
    The latch device may be formed integrally as a single piece, for example, by injection molding of a thermoplastic material.
  • [0012]
    According to one embodiment, the elongate strap hinge has a cross-sectional thickness that is less than the thickness of the cover and base where the cover and base are attached to the elongate strap hinge.
  • [0013]
    The locking mechanism may be any mechanism which holds the cover against the base in a closed position. Exemplary locking mechanisms may include a cotter pin inserted through a hole formed through the cover and the base, a bolt and nut for locking the cover to the base, a threaded auger screw that is threaded through the cover and base, locking them together, or a locking pin that inserts through a slot in the cover and base, or mechanical interaction or interlocking between the cover and base themselves. These exemplary locking mechanisms are illustrative, and many others could alternatively be used.
  • [0014]
    These and other advantages and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0024]
    A detailed description of the latch device of the invention will now be provided with specific reference to the drawings illustrating preferred embodiments of the invention. It will be appreciated that like structures will be provided with like reference designations. The latch device includes a base suitable for attachment to a substrate, an elongate strap hinge, a cover attached to the base by the elongate strap hinge, a slot in the cover and/or base for holding a substrate therein, a hinge guide structure, and a locking mechanism.
  • [0025]
    FIGS. 1A and 1B depict a latch device 100 having a base 102 to which a cover 104 is hingedly attached. The latch device 100 further includes an elongate strap hinge 106 that is attached at one end to the base 102 and at an opposite end to the cover 104. In this way, the cover 104 is hingedly attached to the base 102 and is able to be selectively moved (e.g., rotated) between an open position and a closed position relative to the base 102. The latch device also includes a camming hinge guide structure 108, and a locking mechanism. In a preferred embodiment, the latch device can be made (e.g., by injection molding) from a single type of material, e.g., a thermoplastic material.
  • [0026]
    Because the strap hinge 106 of the latch device 100 is elongated, it is able to bend gradually over a significant portion of its entire length rather than at a single point or line. This results in a hinge that is more resilient and durable over time because it is not overly bent or stressed at any particular point or line. Moreover, because the elongate strap hinge 106 can bend gradually over a significant portion of its entire length, it can be of a thicker, stronger construction compared to a hinge that is required to bend at a single point or line. This results in a hinge that is significantly stronger and more resistant to breakage than it might otherwise be.
  • [0027]
    In some embodiments, the elongate strap hinge 106 will have a cross-sectional thickness that is less than the cross-sectional thicknesses of the adjoining cover 104 and base 102. Nevertheless, it is within the scope of the invention for the elongate strap hinge 106 to have a material cross section that is as thick or thicker than the adjoining cover 104 and/or base 102.
  • [0028]
    According to one aspect of the invention, the elongate strap hinge 106 may be constructed so that the cover 104 remains in an open position relative to the base 102 when the strap hinge 106 is in a relaxed condition. The ability of the cover 104 to remain in the open position without having to apply force to the cover 104 helps facilitate placement of an article (e.g., a rope 110) to be clamped between the cover 104 and the base 102.
  • [0029]
    The latch device 100 includes a camming structure 108 that includes a curved surface that interacts with the elongate strap hinge 106 to assist in causing the hinge 106 to bend gradually along a significant portion of its entire length as the cover 104 is selectively moved between open and closed positions relative to the base 102. The camming structure and curved surface may either comprise an integral part of the cover 104 or base 102, or alternatively, a separate piece attached to the cover 104 or base 102. In the embodiment illustrated in FIGS. 1A and 1B, the camming structure 108 is integrally attached to the cover 104.
  • [0030]
    In FIG. 1A, camming structure 108 is illustrated as having a camming surface 112 and a curved hinge-guiding surface 114. The hinge-guiding surface 114 is an example of a curved surface that interacts with the elongate strap hinge 106 to assist in gradually bending the strap hinge 106 along a significant portion of its entire length as the cover 104 is moved relative to the base 102. The hinge-guiding surface 114 is advantageously curved so as to interact with the elongate strap hinge 106 by distributing forces along a significant portion of its entire length as the cover 104 is moved. Distributing forces along a significant portion of the length of the elongate strap hinge 106, rather than allowing the forces to concentrate at a single location, results in a hinged latch device that is more resistant to breakage of the hinge compared to devices in which the hinge is bent abruptly at a specific point or line. In one embodiment, the hinge-guiding surface 114 may help maintain the cover 104 (in combination with an exemplary locking mechanism discussed more fully below) in the locked position by exerting outward pressure against the elongate strap hinge 106. This, in turn, effectively shortens the length of the cover 104, thereby causing the exemplary locking mechanism to hold the cover 104 more tightly (e.g., so as to remove play).
  • [0031]
    The camming surface 112 is curved or angled in such a way so that it interacts with the base 102 in order to bias the cover 104 toward the open position when the cover 104 is in an unlocked configuration relative to the base 102. This improves access to the inside clamping surfaces of the base 102 and cover 104, facilitating insertion or removal of an article to be held.
  • [0032]
    In the embodiment illustrated in FIG. 1A, camming structure 108 is integrally attached to the inner surface of the cover 104 in a manner so as to extend toward the base 102. Further, and as is shown in particular in FIG. 1B, the camming structure 108 is received within a recess 116 between the base 102 and the elongate strap hinge 106 when the cover 104 is in the closed position. This results in a more compact latch device 100.
  • [0033]
    The latch devices according to the invention include a locking mechanism for maintaining the cover 104 in a closed position once the cover has been closed. As shown in FIGS. 1B and 1C the illustrated embodiment shows an exemplary locking mechanism in which a cotter pin 118 is inserted through a hole 120 formed through the cover 104 and base 102. It will be appreciated that any locking mechanism known in the art may be used to selectively lock and unlock the cover 104 relative to the base 102.
  • [0034]
    The latch device as shown further includes a bearing protrusion 122 extending within a slot 123 in the cover and toward a corresponding slot 124 in the base. Bearing protrusion 122 may be provided on the inside and middle of the cover 104 that extends toward the slot 124 when the cover 104 is in the closed position. The bearing protrusion 122 assists in fixing an article (e.g., a rope, cable, strap, ring, bar, rod, pin, and the like) to be clamped within the slots 123 and 124 when the cover is in the closed state (FIG. 1B). As shown, slots 123 and 124 are advantageously in mating alignment when the cover 104 is in the closed position relative to base 102, although the slots could be misaligned if desired.
  • [0035]
    FIGS. 2A and 2B depict an alternative embodiment of a latch device 200 according to the invention that includes a simplified hinge guide structure disposed on the base. The latch device 200 depicted in FIGS. 2A and 2B includes a base 202 and a cover 204 attached to the base 202 by means of an elongate strap hinge 206. The base 202 further includes a curved end surface 208 that acts as a hinge guide in order to cause the elongate strap hinge 206 to bend gradually over a significant portion of its entire length. In this way, the curved end surface 208 of the base 202 act in similar manner to the curved hinge-guiding surface 114 of the camming structure 108 of the latch device 100 depicted in FIGS. 1A-1B. Thus, as the cover 204 is moved from an open position (FIG. 2A) to a closed position (FIG. 2B), the elongate strap hinge 206 at least partially abuts the curved end surface 208. The abutment between the elongate strap hinge 206 and the curved end surface 208 causes the elongate strap hinge 206 to bend gradually around the curved end surface 208 so as to better distribute the bending forces and bending angles along substantially the entire length of the elongate strap hinge 206.
  • [0036]
    FIG. 3A is a side view that shows another embodiment of a latch device 300 with the cover 304 in an open position relative to the base 302. The cover 304 can be manually opened by rotating it about the elongate strap hinge 306 so that the camming structure 308 just barely abuts an upper surface of the base 302. It will be appreciated, however, that, depending on the nature of the elongate strap hinge 306, it is possible for the cover 304 to be biased either toward or away from the base 302 when the cover 304 is in a fully open position relative to the base 302. In the embodiment shown in FIG. 3A, however, the elongate strap hinge 306 gently biases the cover 304 toward the base 302 in order for the camming structure 308 to lightly contact an upper surface of the base 302 while the cover 304 is in an open position relative to the base 302.
  • [0037]
    As seen in FIG. 3B, when the cover 304 is pushed down toward the base 302, the camming surface 312 of the camming structure 308 makes abutting contact with, and slides against, an upper surface of the base 302, thereby causing the camming structure 308 to be biased in a spring-like fashion towards the elongate strap hinge 306. As a result, the camming structure 308 can act as a spring that exerts an opposing biasing force that, in combination with the camming action of camming surface 312, biases or urges the cover 304 toward the open position relative to the base 302. Thus, if the latch device 300 is in the conformation depicted in FIG. 3B and the cover 304 is released, it may spontaneously spring back to a conformation like the one illustrated in FIG. 3A. It should be understood, however, that the exact resting conformation of the cover 304 is dependent upon the size, shape and relative positions of the camming structure 308 and the upper surface of the base 302 with which it comes into contact.
  • [0038]
    As the cover 304 is pushed down further toward the base 302 as seen in FIG. 3C, the camming surface 312 of the camming structure 308 continues to make contact with the base 302, thus pushing the camming structure 308 further toward the elongate strap hinge 306. Thus, if the latch device 300 is in the conformation depicted in FIG. 3C, and the cover 304 is released, it will spontaneously spring back to a conformation like the one illustrated in FIG. 3A (subject to the actual size, shape and angles of the camming structure 308 and base 302). This tendency of the cover 304 to remain in an open position absent external force is advantageous to the user because it facilitates the insertion of an article to be held between the cover and the base.
  • [0039]
    Additionally, when the latch device 300 is in the conformation illustrated in FIG. 3C, the curved hinge-guiding surface 314 of the camming structure 308 is in contact with the inside surface of the elongate strap hinge 306. This contact between curved surface 314 and the elongate strap hinge 306 distributes forces associated with closing the cover 304 (i.e., while bending the hinge) gradually along the entire contact length between the curved surface 314 and the elongate strap hinge 306 as the cover 304 is progressively closed. This results in the elongate strap hinge 306 bending along its entire length, or at least a significant portion of its entire length, as the cover 304 is closed, rather than bending at a single point or line. This characteristic allows the elongate strap hinge 306 to bend without kinking, thereby decreasing the likelihood of fatigue and unwanted breakage. Because the elongate strap hinge 306 bends gradually along a significant portion of its entire length, rather than abruptly at a distinct localized bending angle, the film hinge 306 can be significantly thicker than film hinges that bend at a discrete localized bending angle. The combination of these characteristics results in a much stronger and more durable hinge that resists breakage when subjected to shearing or bending forces.
  • [0040]
    The cover 304 is held in a closed position by means of mechanical interaction between a locking protrusion 324 that extends from an end of the cover 304 opposite the strap hinge 306 and a locking recess 326 within the base 302. The locking protrusion 324 bends outwardly as the cover 304 is pushed beyond nose 328 on the base 302 to unlock the cover 304, the locking protrusion 324 is withdrawn from the locking recess 326 and flexed up and over nose 328. It should be understood that any combination of protrusions and recesses located on or attached to the cover 304 and/or base 302 may be utilized as the locking mechanism, either alone or in combination with any other locking devices disclosed herein or known in the art.
  • [0041]
    Alternative exemplary locking mechanisms are illustrated in FIGS. 4-8. FIG. 4 illustrates the use of a bolt 418 inserted through a hole 420 in the cover 404 and base 402. A nut 419 is fastened to the bolt 418 so as to secure the bolt 418 within the hole 420. The cover 404 can be selectively locked and unlocked relative to the base 402 by inserting and removing bolt 418 into and out of hole 420.
  • [0042]
    FIG. 5 illustrates a pin 518 that is selectively inserted or withdrawn from a corresponding hole 520 in the front of cover 504 and base 502. The cover 504 can be selectively locked and unlocked relative to the base 502 by inserting and removing pin 518 into and out of hole 520.
  • [0043]
    FIG. 6 illustrates use of a threaded auger screw 618 which is passed through a hole 620 in the front of cover 604 and screwed into a threaded hole 621 in the front of base 602 so as to selectively secure and release the cover 604 to and from the base 602.
  • [0044]
    FIG. 7 illustrates a locking pin 718 which is inserted through a hole 720 and turned in order for a locking tongue 723 to fit within a recess or groove 725 in the cover 704 so as to selectively secure and release the cover 704 to and from the base 702.
  • [0045]
    FIG. 8 illustrates a locking mechanism that includes a latch 81 8 rotatably connected to the base 802 that can be selectively inserted into and withdrawn from an eyelet 820 attached to or formed on cover 804.
  • [0046]
    The foregoing locking mechanisms are exemplary, and any locking mechanism capable of securing the cover to the base may be used.
  • [0047]
    It should be understood that the general concept of a cover attached to a base by means of an elongate strap hinge and a curved surface that helps the strap hinge bend along a substantial portion of its length and/or a camming surface that biases the cover toward an open position can be generalized to be usable together with other known mechanisms or devices. For example, rather than being attached to a base, the cover might be attached to, for example, a box or other container by means of an elongate strap hinge. A curved, hinge guide structure and/or an interactive camming surface that biases the cover toward the open position may also be included in order for the benefits disclosed herein to be extended to lids or covers that can be selectively moved between open and closed positions relative to a box, container, or other substrate.
  • [0048]
    The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are 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.

    wherein the camming structure further includes a curved surface opposite the camming surface that acts as a hinge guide around which at least a portion of the elongate strap hinge contacts and bends when the cover is selectively moved relative to the base so that the elongate strap hinge bends over a significant portion of its entire length.
  9. 9. A latch device as recited in claim 8, wherein the camming structure fits within and substantially fills a void space that would otherwise exist between the base and the elongate strap hinge when the cover is in the closed position.
  10. 10. A latch device as recited in claim 8, wherein the curved hinge guide surface of the camming structure interacts with the elongate strap hinge so as to distribute bending forces along a significant portion of the entire length of the elongate strap hinge when the cover is selectively moved relative to the base.
  11. 11. A latch device as recited in claim 8, wherein the base, cover, and elongate strap hinge are integrally formed together as a single piece.
  12. 12. A latch device as recited in claim 11, wherein the latch device is formed by injection molding a thermoplastic material so that the base, cover, elongate strap hinge, and camming structure are fused together as a single continuous piece of material.
  13. 13. A latch device as recited in claim 8, further including a slot in the base.
  14. 14. A latch device as recited in claim 8, wherein the elongate strap hinge has a cross-sectional thickness that is less than the cross-sectional thicknesses of the cover and base where the cover and base are attached to the elongate strap hinge.
  15. 15. A latch device comprising:
    a base suitable for attachment to a substrate;
    a cover that is movable between open and closed positions relative to the base;
    an elongate strap hinge having a proximal end affixed to the base and a distal end affixed to the cover so that the cover is hingedly attached to the base by the elongate strap hinge and moves by flexing the strap hinge;
    a slot in the base that is spaced apart from the strap hinge so that an object disposed in the slot is prevented from contacting the strap hinge when the cover is in the closed position;
    a hinge guide structure that forms an integral part of the base and includes a curved surface around which at least a portion of the elongate strap hinge bends when the cover is selectively closed relative to the base so that the elongate strap hinge bends over a significant portion of its entire length, at least a majority of the strap hinge contacting the hinge guide structure when the cover is in the closed position; and
    a locking mechanism that selectively locks and unlocks the cover relative to the base.
  16. 16. A latch device as recited in claim 15, wherein the hinge guide structure interacts with the elongate strap hinge so as to distribute bending forces along a significant portion of the entire length of the elongate strap hinge when the cover is selectively moved relative to the base.
  17. 17. A latch device as recited in claim 15, wherein the base, cover, and elongate strap hinge are integrally formed together as a single piece.
  18. 18. A latch device as recited in claim 17, wherein the latch device is formed by injection molding a thermoplastic material so that the base, cover, elongate strap hinge, and hinge guide structure are fused together as a single continuous piece of material.
  19. 19. A latch device as recited in claim 15, further comprising a slot in the cover.
  20. 20. A latch device as recited in claim 15, wherein the elongate strap hinge has a cross-sectional thickness that is less than the cross-sectional thicknesses of the cover and base where the cover and base are attached to the elongate strap hinge.
