Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This is a Continuation-In-Part of co-pending U.S. patent application Ser. No. 09/758,926, filed Jan. 11, 2001.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a mechanical joint, and, more particularly to an improved angle bracket for joining a pair of structural components, e.g., panels used in the construction of various items of furniture including, e.g., tables, chairs, shelving, and cabinets.

[0004] 2. Description of the Related Art

[0005] In general, mechanical joints are widely used to construct items of furniture formed, at least in part, from abutting structural components. Such items of furniture, include, e.g., tables, chairs, shelving units, and cabinets. Many different types of fasteners are commonly used in constructions where abutting structural components are secured to one another. For example, L-shaped brackets, wooden cleats, mortise and tenon combinations, and dowel pins can be utilized to affix abutting components used to form items of furniture.

[0006] One example of a fastener used to secure abutting structural components of, e.g., a cabinet or table is an elongated, metal L-shaped bracket. These fasteners are designed to rest atop and be affixed to the outer surfaces of abutting components. A plurality of apertures are drilled through each leg of the L-shaped bracket through which fasteners, such as screws, are placed. In use, a first leg of the bracket is fixed to a first one of the structural components, the second of the structural components is positioned adjacent to the first component, and the second leg of the bracket is fixed to the second structural component. This type of fastener can be relatively large. The size and the orientation (i.e., with each leg exposed and resting atop a structural component) of these brackets makes them visible and, therefore, not aesthetically pleasing.

[0007] Other mechanical joints used in the construction of furniture, and, particularly, shelving include wooden cleats. Wooden cleats typically comprise an elongate piece of wood having a square or rectangular cross section. In use, the cleat is placed in the joint formed by adjacent structural components and is affixed to each of the structural components. A plurality of fasteners are utilized to secure the wooden cleat to the first component. The second component (commonly a shelf) is positioned atop the wooden cleat. Fasteners can be utilized to secure the second structural component in position atop the wooden cleat. These types of joints are most often used when supporting a shelf, however, they may be used in the construction of other items of furniture including chairs and tables. These types of mechanical joints are relatively large in size, and are entirely exposed in use, and, therefore, are not aesthetically pleasing.

[0008] Additional forms of mechanical joints utilized in the construction of items of furniture include tongue and groove joints as well as mortise and tenon combinations. A tongue and groove joint includes one structural component having a groove and a second structural component having a tongue extending a similar length as the groove. The tongue is of similar shape to that of the groove and is interference fit therein to effect affixation of the components. Similar to the tongue and groove joint is a mortise and tenon combination. A mortise, which is a rectangular aperture, is provided in one component, while a tenon, which is a rectangular projection, is provided on the second component. The tenon is interference fit into the mortise to provide a secure link between the components. Both tongue and groove, and mortise and tenon joints require significant, and somewhat difficult machining producing tight tolerances to enable a good interference fit. The complicated machining of these types of fasteners increases both the time and expense of manufacturing.

[0009] Another fastener used in the construction of furniture is a dowel pin. A plurality of apertures are drilled into each structural component to be secured, so that the apertures in one component align with the apertures in the second component. The tolerance of both the size and the spacing of the apertures must be extremely tight so that the dowel pins may be interference fit into the apertures and so that the mating apertures will properly align. The exacting machining required by dowel pins increases both the time and cost of manufacturing.

[0010] It is desired to provide a mechanical joint for use in furniture which is simple, durable, relatively low in cost, substantially hidden in use, and universal in application.

SUMMARY OF THE INVENTION

[0011] The present invention provides an angle bracket connector for use in joining a pair of structural components used, e.g., to construct furniture components. The bracket has two legs, one for engaging each of the components to be joined. In one exemplary embodiment, one leg is longer than the other. In another exemplary embodiment, one leg has a rounded end, while the other leg has a square end. In certain embodiments, both ends of the angle bracket have rounded ends.

[0012] In one exemplary embodiment, a recess is formed in one of the structural components, and is sized to accommodate a leg of the bracket. In one exemplary embodiment, the geometries of the recess and the bracket itself cooperate to prevent rotation of the bracket. In use, one leg of the bracket is positioned in the recess, with the other leg protruding therefrom for support of the second structural component. The recess is positioned such that when the structural components are placed in abutting relationship, the recess, and, thus, the leg positioned therein, is hidden from view by the end of the second structural component. For the purposes of this document, "abutting" is meant to encompass situations in which the components are actually touching as well as situations where the components are in close proximity.

[0013] In another exemplary embodiment, a leg of the bracket is secured to a face of one of the structural components. In this embodiment, the second structural component includes a recess sized to accommodate the leg of the angle bracket secured to the first structural component. In use, the second structural component is positioned such that when the structural components are placed in abutting relationship, the recess accommodates the leg of the angle bracket connector secured to the first structural component. In this way, the second structural component removes from view the leg of the angle bracket connector secured to the first structural component.

[0014] The invention, in one form thereof, comprises a mechanical joint including a first structural component having a face, a bracket having a pair of legs, with a first one of the legs of the bracket secured to the face of the first structural component, and a second structural component having an end and a face, with the face of the second structural component including a face bore formed therein, and the end of the second structural component abutting the face of the first structural component, with the face bore receiving the first leg of the bracket.

[0015] The invention, in another form thereof, comprises an item of furniture having a mechanical joint affixing abutting structural components. The item of furniture of this form of the present invention comprises a first structural component and a second structural component, with the second structural component having an end abutting a face of the first structural component; and a bracket having a pair of legs disposed at an angle to each other, the bracket joining the first and the second structural components, a first one of the legs of the bracket disposed between the end of the second structural component and the face of the first structural component, the first one of the legs of the bracket is affixed to the face of the first structural component and the second structural component has a face including a face bore intersecting the end of the second structural component and receiving the first leg of the bracket.

[0016] The invention, in a further form thereof, comprises a method of constructing an item of furniture. The method of this form of the current invention includes the steps of: providing a first structural component and a second structural component, the first structural component having a face, the second structural component having a face and an end; providing a bracket having a first leg and a second leg; securing the first leg to the face of the first structural component; forming a face bore in the face of the second structural component; and abutting the end of the second structural component with the face of the first structural component such that the first leg of the bracket is contained within the face bore and the second structural component rests atop the second leg of the bracket.

[0017] An advantage of the present invention is that the bracket is substantially hidden from view and yet is relatively strong.

[0018] Another advantage of the present invention is that it is simple in construction.

[0019] A further advantage of the present invention is that it is universal in application in that it may be used in the construction of any type of structure having abutting components including, e.g., tables, chairs, shelving, and cabinets.

[0020] Yet another advantage of the present invention is that it is relatively low in cost.

DETAILED DESCRIPTION OF THE INVENTION

[0044] Referring to FIG. 1, furniture 20 is constructed from a plurality of structural components including panels such as end or side panels 24 (FIGS. 2 and 3), back panel 26 (FIG. 4), and top and bottom panels 28 (FIG. 5). Furniture 20, can be, e.g., a television stand. Top and bottom panels 28 share the same construction, as illustrated in FIGS. 1 and 5. Referring to FIGS. 6, and 9-12, brackets 30 are designed to secure adjacent structural components to one another to construct furniture 20 (FIG. 1). Each end panel 24 is fixed to back panel 26, and top and bottom panels 28 are disposed between end panels 24, being secured at each end to end panels 24 by brackets 30.

[0045] Furniture constructed utilizing the mechanical joint of the current invention can include many types of furnishing for a home or office, including, e.g., a desk, a bookcase, a television stand, cabinets, or the like. When constructing this type of furniture, structural components are placed in abutting relationship, with an end of one structural component, such as end 32 of back panel 26, abutting a surface of another structural component, such as surface 34 of end panel 24 (FIG. 1). The abutting relationship between structural components of furniture 20 allows at least a portion of brackets 30 to be hidden from view as will be discussed herein below.

[0046] Referring to FIGS. 2, 3, 4, and 5, end panels 24, back panel 26, as well as top and bottom panels 28 include a plurality of recesses 38, 44. Recesses 44 of end panels 24 are positioned along the edge of end panels 24 and, in use, align with a number of recesses 38 in back panel 26 as well as a number of recesses 38 in top and bottom panels 28. This allows one leg of brackets 30 to be received in recess 44 in end panel 24 and the second leg of brackets 30 to be received in recesses 38 in back panel 26 and top/bottom panels 28.

[0047] As illustrated in FIGS. 2-8, 13 and 14, two different types of recesses (38, 44) are formed in the structural components, each type having a different shape. First recess 38 is machined, e.g., into back component 26 (FIG. 4) and includes rounded end 40 at one end intersecting side walls 42 extending to the opposite end thereof. The end of recess 38 opposite rounded end 40 is open. Second recess 44 has an oblong or generally elliptical shape. Second recess 44 includes a pair of rounded ends 46, one at either end thereof, with side walls 48 extending therebetween.

[0048] Recesses 44 are disposed in the structural components of furniture 20 in either a substantially vertical or a substantially horizontal orientation depending upon the orientation of the structural components to be joined thereto. For example, recesses 44 along back side 70 of end panels 24 are disposed substantially vertically, while recesses 44 positioned generally along the upper and lower edges of panels 24 are disposed substantially horizontally. Generally, recesses 44 are oriented similar to the structural component to be affixed thereto via bracket 30. Since furniture 20 includes only horizontally and vertically oriented structural components, only horizontally and vertically oriented recesses are required. In items of furniture having structural components oriented other than horizontally or vertically, recesses 44 would be positioned accordingly. Recesses 38 and 44 are provided with pre-drilled apertures 49 for affixation of bracket 30 (FIGS. 6-8). In one exemplary, apertures 49 in recesses 38 are positioned slightly off center (on the order of 0.5 mm toward rounded end 40) with respect to the mating recess in bracket 30. The off center position of apertures 49 in recess 38 draws the relevant structural components together.

[0049] Furniture 20 is constructed such that abutting structural components are positioned with an end of a first structural component covering an oblong recess formed in a face of a second structural component. With particular reference to furniture 20 illustrated in FIG. 2, ends 32 (FIG. 4) of back panel 26 abut end panels 24 such that back panel 26 covers oblong recesses 44 positioned along back side 70 of end panels 24. Similarly, ends 72 of top and bottom panels 28 abut end panels 24 such that top and bottom panels 28 cover oblong recesses 44 positioned generally along the top and bottom edges of end panels 24, respectively. Recesses 38 and 44 are positioned on adjacent structural components so as to align with one another, allowing affixation of brackets 30 thereto. Recesses 38 and 44 have a depth allowing the structural components they are formed in to be placed in abutting relationship. For example, with bracket 30 disposed in recesses 38 and 44, and back panel 26 abuts end panel 24 so as to cover recess 44, and the leg of bracket 30 contained in recess 44 so that this leg of bracket 30 is hidden from view. As illustrated in FIGS. 1 and 4, recesses 38 are formed in surface 35 which comprises the forward face of back panel 26. Recesses 38 are thusly positioned for illustrative purposes only. In use, recesses 38 could be formed in the back face (not shown) of back panel 26 so that bracket 30 would be entirely concealed from view. Recess 38 is not essential for hiding the leg of bracket 30 contained in recess 44 and, therefore, may be excluded.

[0050] Referring to FIG. 6, bracket 30 is illustrated prior to affixation to end panel 24 and panel 28. Recess 44 is machined into end panel 24 and receives square leg 50 of bracket 30. Similarly, recess 38 is machined into panel 28 for receiving rounded leg 52 of bracket 30. In use, square leg 50 is secured within oblong recess 44 in end panel 24, and panel 28 is thereafter positioned in abutting relationship to end panel 24 such that rounded leg 52 of bracket 30 is received within recess 38 of panel 28. In one exemplary embodiment, rounded leg 52 of bracket 30 is affixed to panel 28 via fastener 64. It is further contemplated by the present invention to provide a bracket 30 for securing a generally horizontal structural component, wherein the rounded leg of the bracket is without an aperture to accommodate fastener 64. When assembled, end 72 of panel 28 covers oblong recess 44 and square leg 50 of bracket 30, thus concealing square leg 50 of bracket 30 from view. In use, rounded leg 52 of bracket 30 is substantially flush with aperture 38 as well as surface 33 of panel 28. FIGS. 1A and 1B illustrate bracket 30 secured to panel 28 and end panel 24.

[0051] The current invention further contemplates a construction in which recess 38 extends into end 72 of panel 28 such that when bracket 30 is placed therein, bracket 30 is flush with end 72 and surface 33 of panel 28. In such an embodiment, recess 44 in end panel 24 would be unnecessary. In such an embodiment, bracket 30 would be affixed to surface 34 of end panel 24 with panel 28 being placed in abutting relationship with end panel 24 such that bracket 30 is received in recess 38.

[0052] Referring now to FIGS. 9-11, bracket 30 is, in one exemplary embodiment, constructed from steel and includes legs 50, 52. Generally, bracket 30 is constructed from material having sufficient strength to maintain the structural integrity of the furniture which it is used to form and to support the items which the furniture is made to support (e.g., a television on a television stand). Bracket 30 is L-shaped having square leg 50 disposed approximately perpendicularly from rounded leg 52. As indicated supra, both legs 50, 52 can be square, or round. Referring to FIG. 9, the angle .THETA. between legs 50 and 52 of bracket 30 is illustrated as being approximately 90.degree., however, .THETA. may be at any acute or obtuse angle necessary to position a pair of structural components as desired. As is known in the art, such a construction would require a mitered end on one of the structured components to be joined, so that the structural components could be placed in abutting relationship. As shown in FIGS. 9-12, legs 50 and 52 are each provided with aperture 62 through which fastener 64 (FIG. 6), such as a screw or the like, may be placed. Chamfer 66 accommodates the head of fastener 64 so that fastener 64 is flush with the leg of bracket 30 which it is utilized to secure.

[0053] Referring to FIGS. 13 and 14, legs 50 and 52 of bracket 30 are shown disposed in recesses 44 and 38, respectively. Recess 38 is machined to substantially the same size and shape of leg 52. Square leg 50 is disposed in oblong recess 44 such that each of the pair of oppositely disposed flat edges 68 of bracket 30 are parallel to side walls 48 of recess 44 so that rotation of bracket 30 is thereby limited. In one exemplary embodiment, recess 44 is dimensioned such that square leg 50 fits snugly between side walls 48 so that rotation of bracket 30 about fastener 64 in leg 50 is prohibited. In alternative embodiments, the distance between side walls 48 will be such that slight rotation of leg 50 will be allowed. However, it is preferred that recess 44 is constructed such that rotation of leg 50 and consequently bracket 30 is substantially prohibited. Recess 44 is machined to have an oblong, or generally elliptical shape, with rounded ends 46, since a square recess is more difficult to machine. However, recess 44 may be of any shape which prevents rotation of bracket 30 while being sized for concealment by an abutting structural component. Furthermore, leg 50 can be any non-rounded (e.g., polygonal) shape that will cooperate with the geometry of recess 44 to substantially prohibit rotation of bracket 30.

[0054] Bracket 30 is substantially universal in application. Brackets 30 may used to secure any first and second structural components together to produce a portion of a item of furniture, such as furniture 20. Brackets 30 may be used to secure an end panel to a back panel, a top panel to an end panel, or a bottom panel to a back panel, for example. While being substantially universal in application, and relatively strong, brackets 30 are at least partially (and, many times, completely) hidden from view in any of the mentioned orientations to provide an aesthetically pleasing item of furniture.

[0055] FIGS. 1C, 1D, and 15-17 illustrate a second embodiment mechanical joint in accordance with the present invention. FIGS. 1C, 1D, and 15-17 illustrate a mechanical joint formed between end panel 24' and panel 28'. The second embodiment mechanical joint illustrated in FIGS. 1C, 1D, and 15-17 can be utilized to secure any two adjacent structural components as described above with respect to the first embodiment mechanical joint disclosed herein. As illustrated in FIG. 15, bracket 30' is secured to surface 34' of end panel 24' via fastener 64. Fastener 64 traverses aperture 62' in first leg 50' of bracket 30' to secure bracket 30' to end panel 24'. As fastener 64 transverses aperture 62' in first leg 50' of bracket 30', chamfer 66' accommodates the head of fastener 64 so that fastener 64 is flush with first leg 50' when affixation of bracket 30' to surface 34' of end panel 24' is complete.

[0056] As illustrated in FIG. 15, face 33' of panel 28' includes face bore 37 formed therein. Generally, face bore 37 is bored into face 33' of panel 28' with a bit. For the purposes of this document, "face bore" generally describes a substantially circular aperture formed by a bit having an axis of rotation substantially perpendicular to the face of the structural element in which the face bore is being formed. The boring operation utilized to form face bore 37 is generally easier to perform than the routing operations required to form recesses 38, 44 described above. FIGS. 16 and 17 illustrate face bore 37 in detail. As illustrated, face bore 37 comprises a rounded recess formed in face 33' of panel 28'. In one exemplary embodiment, face bore 37 is formed with the center line or longitudinal axis of the bit displaced from the end of panel 28'.

[0057] Face bore 37 is sized to accommodate first leg 50' of bracket 30' on formation of a mechanical joint in accordance with the second embodiment of the present invention. This arrangement is illustrated in FIGS. 1C and 1D. The sides of leg 50' of bracket 30' are, in one exemplary embodiment, beveled. In this exemplary embodiment, the radius of curvature of the bevel of the sides of leg 50' of bracket 30' substantially equals the radius of curvature of face bore 37. With this in mind, face bore 37 can form an interference fit with leg 50' of bracket 30' positioned therein. Furthermore, in another exemplary embodiment, second leg 52' of bracket 30' has a width greater than the width of first leg 50' of bracket 30' to better cover face bore 37 on formation of a mechanical joint in accordance with the second embodiment of the present invention.

[0058] In construction, bracket 30' is secured to surface 34' of end panel 24' via fastener 64, and panel 28' is thereafter placed in abutting relationship with end panel 24', with face bore 37 accommodating first leg 50' of fastener 30'. In one embodiment, a second fastener (64) may be utilized to secure second leg 52' of bracket 30' to panel 28'. Furthermore, panel 28' may include a second recess similar to recess 38 depicted in FIG. 6 and described supra to accommodate second leg 52' of bracket 30'. As illustrated in FIG. 15, end panel 24', and panel 28' may be provided with pre-drilled apertures 49 to facilitate affixation of bracket 30' thereto via fastener 64. As illustrated in FIG. 1C, when the mechanical joint of the second embodiment mechanical joint of the present invention is complete, face bore 37 is hidden from view.

[0059] While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
