FIELD OF THE INVENTION
Embodiments of the present invention are generally related band buckles and bands for securing objects. More specifically, embodiments of the present invention provide a band buckle device adapted to receive and secure a band including, but not limited to, a metal band or strap.
BACKGROUND OF THE INVENTION
In the art of securing members together it has long been the practice to employ a strap or band of metal which encircles or otherwise extends about a member or members, or a plurality of articles in a bundle, which is tensioned and its ends then secured together with a locking member, variously referred to as a seal, sleeve, or buckle. The buckle is commonly formed of ductile sheet material, such as steel, which is bent into the form of a tube having a rectangular channel in which the band ends are disposed in lapped relation after which a cold crimping or swaging action locks the buckle and band ends together. In one form of conventional lock, portions of the band edges are sheared and bent laterally to provide locks engageable with corresponding apertures or sheared portions in the buckle, an example of which is disclosed in U.S. Pat. No. 1,988,742, which is hereby incorporated by reference in its entirety. As will be apparent, the cross section of the band is reduced at its transverse points where the shear locks or lugs occur, the strength of the band in tension is reduced.
In another form of lock, as exemplified by U.S. Pat. No. 190,641, which is hereby incorporated by reference in its entirety, the band is not weakened by shearing portions of its cross section. Rather, a suitable aperture is provided in the buckle into which the band is crimped, forming a lock, but maintaining the cross section of the band essentially the same as prior thereto.
Band clamps are used to bundle a plurality of objects or to attach one object to another and comprise a band with an interconnected buckle (sometimes referred to as a seal). The band is wrapped around the object or objects, a free end of the band is inserted into the buckle, the band is tensioned, and the buckle is interconnected to the band to maintain band tension. A hand-held tool is often used to tension the band and to fix the buckle to the band. The tool is used to remove excess band after the band clamp is locked. Such tools commonly employ a ratcheting mechanism that rotates a winding mandrel that tensions the band.
U.S. Pat. No. 3,641,629 to Beardsley, which is hereby incorporated by reference in its entirety, discloses a band buckle, a method of making the same, and a method of applying a band buckle. Various features and tools provided in Beardsley '629 are contemplated for use within embodiments of the present disclosure. Beardsley '629 fails to disclose, however, various features of the present inventions including, for example, devices and methods for securing a band and band buckle
U.S. patent application Ser. No. 15/269,333, which is hereby incorporated by reference in its entirety, discloses a band clamping tool. Devices and features shown and described in application Ser. No. 15/269,333 are contemplated use with devices of the present disclosure.
U.S. Pat. No. 8,424,166 to Dorneman et al., which is hereby incorporated by reference in its entirety, discloses a locking band clamp, a locking tool and a method of forming a locking band clamp. Various features and devices shown and described in U.S. Pat. No. 8,424,166 to Dorneman et al. are contemplated for use with embodiments of the present invention.
SUMMARY OF THE INVENTION
It is one aspect of embodiments of the present invention to provide a band clamp with a buckle for receiving a band, the buckle comprising an aperture through an outer surface of the buckle. A band is positioned within the buckle, and a deformation is formed in the band and located generally adjacent to the aperture, the deformation preventing relative motion between the band and the buckle. A curled portion of the band is provided and engages an edge of the outer surface of the buckle to prevent relative motion of the buckle relative to the band. The band comprises a length and at least one profrusion is provided on the length and distal from the buckle, the protrusion comprising at least one of a bend and a step and wherein the protrusion comprises a departure from a general path of the band.
In another embodiment, a band damp system is provided, the system comprising a buckle for receiving a band, the buckle comprising at least one peripheral opening for receiving the band, and an aperture provided through an outer surface of the buckle. A band is positioned within the buckle, and the aperture of the buckle comprises an aperture sidewalk the aperture sidewall operable to be provided in force-transmitting communication with the band to prevent relative motion of the buckle relative to the band. The band comprises a length and at least one protrusion is provided on the length and distal from the buckle, the protrusion comprising at least one of a bend and a step and wherein the protrusion comprises a departure from a general path of the band.
In various embodiments, methods of providing and applying a clamp are provided. In one embodiment, a method of securing an object with a band clamp is provided, the method comprising: providing a buckle for receiving a band, the buckle comprising: an aperture through an outer surface of the buckle, and a band positioned within the buckle; and the band comprising a length and at least one protrusion provided on the length and distal from the buckle, the protrusion comprising at least one of a bend and a step and wherein the protrusion comprises a departure from a general path of the band; providing the band around an object to be secured; inserting a first end and a second end of the band into the buckle; providing a deformation in the band proximal to the buckle, and wherein the deformation provides force-transmitting communication between the band and the buckle; and monitoring the at least one protrusion of the band to determine of the object has experienced a movement or a deformation.
In various applications, it may be desirable to provide a band clamp that is capable of providing a visual indication that a deformation has occurred and wherein this visual indication occurs prior to a catastrophic failure of the buckle. For example, various pressure vessels and pipes may be secured using band clamp systems of the present invention. In various embodiments, band clamps systems of the present invention comprise bands having at least one protrusion in an original or un-deformed state. The continued presence of the at least one protrusion generally indicates that the band and associated object has not been deformed. If, however, the protrusions have deformed, stretched out, or otherwise been altered, such an occurrence indicates a change or problem with the associated object. For example, where the band and clamp are provided around a pipe or a flush cartridge of a toilet, the flattening or change of the protrusion in the band indicates that the pipe or flush cartridge has been compromised and may need replacement or repair. In preferred embodiments, such a flattening or change in the protrusion occurs prior to a failure of the band and/or buckle. Preferably, a weak point or failure point is provided at the buckle, but the band and buckle comprise a structural integrity even subsequent to a change in the protrusion(s) of the band.

DETAILED DESCRIPTION
FIG. 1 shows a buckle 2 according to one embodiment of the present invention that comprises an upper portion 4 and a lower portion 6. In some embodiments, the buckle 2 is formed from a single sheet of metal and is provided in the shape shown in FIG. 1 by providing a first and second bends 10 wherein the bends 10 serve as a transition point between the upper portion and the lower portion 4, 6. The upper portion 4, lower portion 6, and bends 10 generally comprise an outer surface, and an at least partially confined internal volume is provided for receiving a band or a strap, for example.
One or more gaps 8 are provided in the upper portion 4. The gap 8 may be of various dimensions, and no limitation with respect to size of gap and/or the proportions of the gap 8 with respect to additional buckle features is provided herewith. The buckle 2 further comprises a central aperture 12. The central aperture 12 is provided as a rectilinear aperture in the embodiment shown in FIG. 1, but may comprises various different geometric shapes including, but not limited, circular shapes, triangular shapes, and irregular shapes. The buckle 2 also comprises first and second peripheral openings 7a, 7b. The peripheral openings 7a, 7b are adapted to and operable to receive a band or strap (not shown in FIG. 1).
FIGS. 2A-2B are top and bottom perspective views of the buckle 2 according to the embodiment of FIG. 1. As shown, a band 14 extends into and/or through the buckle and is secured by means of the buckle 2. Specifically, the band 14 is disposed within the buckle 2 and extends through at least one of the first and second peripheral openings 7a, 7b. The band 14 comprises a thickness that is sufficiently small to be accommodated between the upper and lower portions 4, 6 of the buckle. In some embodiments, the band 14 originally comprises a substantially smooth or flat band to facilitate insertion of at least a portion of the band 14 into the buckle 2. Once the band 14 is provided in a desired position relative to the buckle, the band 14 is deformed to secure this desired position. In various embodiments, a method of positioning of the band 14 comprises applying a tension to the band and/or securing the band around an additional object (e.g. a sign post, pipe, cables, etc.). A punch or similar tool is used to deform a portion of the band 14, and a deformation 16 is provided on the band 14 and within an area or volume defined by the buckle. The deformation 16 of FIGS. 2A-2B comprises a trough-shaped feature that generally comprises a depression in the view of FIG. 2A, and which extends downwardly. The deformation 16 in the band 14 results in at least a first sheared edge 18 with a substantially flat or planar surface provided adjacent to a sidewall 13 of the aperture 12. As shown in FIGS. 2A-2B, the deformation 16 comprises first and second sheared edges 16, 18 provided adjacent to and/or in contact with opposing sidewalls 13 of the aperture. The provision of first 18 and second 20 sheared edges provided that the band 14 is translationally fixed with respect to the buckle 2, at least after the deformation 16 is provided in the band 14.
As shown in FIGS. 2A-2B, and as will be recognized by one of ordinary skill in the art, the deformation 16 extends across only a portion of the width W of the band 14. Extending the deformation 16 across an entirety of the width W of the band 14 would sever the band 14 and fail to provide a connection.
FIG. 3 is a cross-sectional perspective view of the buckle 2 and band 14 according to the embodiment of FIGS. 1-2B, and taken at line A-A of FIG. 1. As shown in FIG. 3, the buckle 2 is provided with a band 14 at least partially inserted therein. The band 14 is provided with a deformation 16, that is formed with a punch or similar tool. The deformation 16 comprises a cut or first sheared edge 16 on one side of the deformation and a second sheared edge 18 on a second side of the deformation 16. The sheared edges 16, 18 comprise substantially planar surfaces that operate as contact surface or force-transmitting surfaces to secure the band 14 to the buckle 2 by interaction and contact with sidewalls 13 of the aperture 12. As shown in FIG. 3, an upper portion of the aperture 12 is operable to receive a tool (not shown), and the lower portion of the aperture 12 receives the deformation 16. It will be recognized, however, that this arrangement could be reversed, and the deformation may comprise an upwardly-extending deformation.
FIG. 4 is perspective view of a buckle 2 and associated band 14 according to another embodiment of the present invention. As shown in FIG. 4, the buckle comprises the same construction as the buckle 2 provided in FIG. 1. First and second ends of the band 14 are positioned within the buckle. Although not shown in FIG. 4, the band 14 is looped or wrapped around one or more objects, and secured by means of the buckle 2. Accordingly, a first end 14a of the band 14 extends from one end of the buckle, and a second end 14b of the band extends from a second end of the buckle. The band 14 is secured within the buckle, and the shape of band is thus fixed, by providing a deformation 16 on the band 14 and on a portion of the band that is disposed at least partially within the buckle 2. The deformation 16 provided in FIG. 4 comprises a preferred shape, with a sheared edge 26 provided on one end of the deformation 16 and a tapered shape extending away from the sheared edge 26.
As also shown in FIG. 4, the second end 14b of the band comprises a curled edge 15 to provide additional securement of the band 14 to the buckle 2. Although not shown in FIG. 4, the first end 14a of the band 14 is also contemplated as comprising a curled edge adjacent to a portion of the buckle. A curled edge on the first end 14a of the band 14 may be provided in addition to or in lieu of the curled edge 15 provided on the second end 14b of the band 14.
FIG. 5A is a cross-sectional perspective view of a buckle 2 and strap according to the embodiment of FIG. 4. As shown, a first end 14a and a second end 14b of the band 14 are passed through the buckle 2. A portion of the band 14 that is generally disposed within the buckle 2 is then deformed to create a deformation 16. The deformation 16 is preferably formed by providing a punch or similar tool in contact with an upper portion of the band 14 and through the aperture 12 on the upper portion of the buckle 2. The aperture 12 on the upper portion of the buckle 12 serves as a guide member for contacting the band 14 with a tool and creating this deformation 16. As shown in FIGS. 5A-5B, a portion of both the first end 14a and the second end 14b of the band 14 that is disposed within the buckle 2 is deformed such that sheared edges of the band 14 are provided in contact with an aperture sidewall. The first end 14a and the second end 14b are thereby secured relative to the buckle 2 and relative to each other. One of ordinary skill in the art will thus realize that the band is thereby secured around an object that the band surrounds (not shown in FIGS. 5A-5B).
FIG. 6 is a top perspective view of a buckle 2 and associated band 14 according to one embodiment of the present invention. The buckle 2 of FIG. 6 comprises substantially the same construction as the buckle 2 of FIG. 1. As shown in FIG. 6, the band comprises a first end 14a and a second end 14b. The band extends in a loop (not shown in FIG. 6) such that the band 14 may be passed around and/or encircle an additional object. Opposing ends 14a, 14b of the band 14 are inserted into opposing sides of the buckle 2 and are provided in an overlapping arrangement. Once the band 14 is provided in a desired orientation with at least a portion of the first end 14a and/or the second end 14b provided within the buckle 2, the band 14 is deformed to secure the band to the buckle 2.
Specifically, and as shown in FIG. 6, the first end 14a and the second end 14b of the band 14 are inserted into opposing sides of the buckle 2 and are provided in an overlapping arrangement. A punch or similar tool is preferably used to deform, bend, and/or shear a portion of the band, the portion comprising a deformation 16 that extends downwardly in FIG. 6.
FIGS. 7-8 are cross-sectional perspective views of the embodiment of FIG. 6 which show an interaction between sheared edges of the deformation 16 and the buckle 2 such that the band 14 is restrained within the buckle. As shown in FIGS. 7-8, the deformation 16 provided in a portion of the first end 14a and a portion of the second end 14b of the band 14 produces at least one sidewall or sheared edged 18 that is operable to contact a sidewall 13 of the aperture 12 and substantially prevent movement of the buckle 2 with respect to the band 14. One of ordinary skill in the art will recognize that if no deformation 16 as shown and described herein is provided in the band 14, the ends of the band 14 will be able to freely translate in and out of the buckle. The deformation 16 produces a first sheared edge 18 on both the first end 14a and the second end 14b of the band 14. The deformation 16 also produces a second sheared edge 20 on the first end 14a and the second end 14b of the band 14, and wherein the second sheared edge 20 is provided in opposing relationship to the first sheared edge 18. The sheared edges 18, 20 are provided in force-transmitting communication with an aperture sidewall 13 on both sides of the aperture 12 of the buckle 2.
FIG. 10 is a perspective view of a buckle 30 according to another embodiment of the present disclosure. As shown, the buckle 30 comprises a first and second bend 32 to create an at least partially confined volume. The buckle 30 comprises peripheral openings 34 to accept and accommodate a band or strap (for example). The buckle 30 further comprises first and second apertures 36, 38, wherein at least one of the apertures is provided to accommodate a deformation of a band, and at least one of the apertures is provided to receive or accommodate a tool for forming the deformation. The apertures 36, 38 of the embodiment of FIG. 10 comprises substantially circular apertures operable to create and/or accommodate a substantially circular deformation in the band (not shown in FIG. 10). The buckle of FIG. 10 operates under the same principles as the buckle shown in FIG. 1, for example, but comprises different structural and geometric elements as shown in FIG. 10.
FIG. 11 is a bottom plan view of the buckle 30 according to the embodiment of FIG. 10, and wherein a deformation 42 provided in a band extends at least partially in the buckle 30. The deformation 42 comprises at least one of a circular, conical, and a frustoconical depression provided in at least a portion of a band that extends into the buckle 30. Preferably, the deformation 42 is of a size and geometry such that an outer circumference of the deformation 42 extends to make contact with the lower aperture 38 provided in the buckle, and a movement of the band relative to the buckle 30 is substantially prevented.
FIG. 12 is a side elevation view of the buckle 30 according to the embodiment of FIG. 10. As shown in FIG. 12, the buckle 30 is provided with a band 40 extending at least partially therethrough. The band 40 is provided with a deformation 42 which extends at least partially into a lower aperture 38 provided in the buckle 30. In various methods of the present invention, a punch is provided and inserted through the upper aperture 36 to deform the band 40 and create a deformation 42 that extends downwardly (at least in FIG. 12). The communication between the deformation 42 and the buckle 30 provides a connection between the two components and substantially fixes the relative position of the buckle 30 and the band 40.
FIG. 13 is a detailed view of the deformation 42 of the band 40. As shown in FIG. 13, the deformation comprises an indentation or depression in the band, and wherein the indentation comprises a ridge 44. The ridge 44, which is preferably formed from the shape of the punch tool comprises and provides an enhanced contact and load-bearing point to provide additional grip or securing strength between the buckle 30 and the band 40.
FIG. 14A is an elevation view of a band clamp system 50 according to one embodiment of the present invention, wherein the system 50 comprises a buckle 52 and a band 54. The buckle 52 may comprise any number or combination of buckle features as shown and described herein. The band 54 comprises at least one protrusion 58. In the depicted embodiment of FIG. 14A, the protrusion 58 comprises a diversion of a general path of the band and does not comprise an additional component (such as a welded-on or fastened component). The band 54 comprises a first end 55 and a second end 56 that are preferably wrapped around an additional object or component (not shown) and secured at or to the buckle 52. The ends 55, 56 may be cut, crimped, or altered as desired.

FIG. 19 is an elevation view of a band clamp system 50 according to another embodiment of the present invention, wherein the system 50 comprises a buckle 52 and a band 54. The buckle 52 may comprise any number or combination of buckle features as shown and described herein. The band 54 comprises at least one protrusion 58. In the depicted embodiment of FIG. 19, the protrusion 58 comprises a diversion of a general path of the band and does not comprise an additional component (such as a welded-on or fastened component). The band 54 comprises a first end 55 and a second end 56 that are preferably wrapped around an additional object or component (not shown) and secured at or to the buckle 52. The ends 55, 56 may be cut, crimped, or altered as desired. In contrast with the embodiment provided in FIG. 14A, the protrusions 58 comprise substantially pointed features which extend from an otherwise curvilinear band member 54. The protrusions 58 comprise first, second and third bends or crimps to form the protrusion, each of which are deformable when the band 54 is expanded. It will be recognized that the protrusions 58 shown and described herein are not limited to any particular shape. Various different protrusions and bends may be provided. In an alternative embodiment, at least one protrusion 58 provided on a band 54 comprises an accordion-like structure, with multiple points of bending where deflection may occur.
Where the term “substantially” is used herein, one of ordinary skill in the art will readily understand the meaning of such a term in its context. For example, the terms “substantially flat” or “substantially circular” will be understood to indicate that minor variations in manufacturing and natural bending of components may alter devices of the present invention such that surface are not exactly flat or objects are not exactly circular.
