DETAILED DESCRIPTION
(10) Referring now to the drawings and in particular to
(11) Stand 20 includes a top plate 22 and a front flange 24 extending from or connected to top plate 22. Top plate 22 and front flange 24 can be for example about 0.125 inch (3.2 mm) thick or thicker if desired. Front flange 24 is placed in front of the flat screen device, such as, a television, computer monitor, video monitor, etc. Front flange 24 accordingly does not extend too far downwardly, so as not to block the viewing of the image displayed on the flat screen device. Top plate 22 in one embodiment is six inches (15.2 cm) wide (dimension extending along top of the flat screen device) and 5.5 inches (14.0 cm) deep (dimension extending from back of the flat screen device). Top plate 22 can have different widths and depths, e.g., can have a twelve inch (30.4 cm) double width and two or more ratcheting subassemblies to support the larger width as illustrated below.
(12) Top plate 22 and front flange 24 are metal or plastic in one embodiment and are provided respectively with top surface padding 26a, bottom surface padding 26b and inner flange surface padding 26c. Padding 26a, 26b, and 26c can be a softer metal, plastic, covered foam, covered sponge, rubber, foam rubber, wood, or combinations thereof. In an embodiment padding 26a, 26b and 26c is adhered to, heat sealed to, sprayed onto and/or mechanically attached to the respective mating surfaces of top plate 22 and front flange 24. Padding 26a, 26b, and 26c helps to prevent scratching of the flat screen device. Padding 26a, 26b, and 26c also helps to prevent objects set onto top plate 22 from scratching the top plate, and may also help to prevent the objects from slipping.
(13)
(14) Mount 30 includes a mounting flange 32a and a ratchet base 32b. In one embodiment mounting flange 32a and ratchet base 32b are bent or formed from the same piece of metal or plastic forming mount 30. In another embodiment, mounting flange 32a and ratchet base 32b are separate pieces that are secured together, e.g., via welding, adhesive, and/or via mechanical securement. Mounting flange 32a and ratchet base 32b can be made of a thicker material than for stand 20, e.g., on the order of 0.125 inch (3.2 mm) thick to 0.375 inch (9.5 mm) thick.
(15) Ratchet base 32b includes or defines a center hole 34 for receiving the threaded stud 54 of torque screw 50 or fastener. Center hole 34 can be a through-hole sized to allow the threaded stud 54 of torque screw 50 to pass through. Center hole 34 can alternatively be female threaded to threadingly engage the male threads of the threaded stud 54 of torque screw 50.
(16) Ratchet base 32b also includes, defines or attaches to a circular set of ratchets 36, which engage mating ratchets of arm 40. Individual ratchets 36 have a triangular cross-section in one embodiment and are disposed radially about a center point to form a circle or ring. Ratchets 36 extend outwardly from a base portion of ratchet base 32b in a same direction as the direction in which mounting flange 32a extends from ratchet base 32b of mount 30.
(17) In one embodiment, ratchets 36 or ratchet ring 36 is a separate plastic or metal piece that abuts up against ratchet base 32b of mount 30. For example, separate ratchet ring 36 can be a molded plastic piece made of any of the plastics listed above, or of a tougher plastic, such as Teflon. In another embodiment, ratchets 36 or ratchet ring 36 is formed with ratchet base 32b and mount 30. For example, ratchet ring 36 can be machined from the same piece of metal with ratchet base 32b to form mount 30. Or, ratchet ring 36 can be formed from the same plastic mold as ratchet base 32b to form mount 30.
(18) Mounting flange 32a and ratchet base 32b of mount 30 each define mounting holes 38, and in the illustrated embodiment, define three mounting holes 38. The mounting holes 38 of mounting flange 32a (illustrated best in
(19) The mounting holes 38 of ratchet base 32b of mount 30 can likewise be either through holes or be threaded.
(20) If center hole 34 of ratchet base 32b of mount 30 is a through hole, then bracket 60 can be provided, wherein the center hole 62 of bracket 60, which aligns with center hole 34 of mount 30, is threaded to threadingly receive the threaded stud 54 of torque screw or fastener 50. Bracket 60 in turn includes mounting holes 68, which align with the mounting holes 38 of ratchet base 32b. Mounting holes 68 of bracket 60 and mounting holes 38 of ratchet base 32b can both be through holes that accept bolts or fasteners, which in turn threadingly engage nuts to fasten bracket 60 to ratchet base 32b of mount 30. Alternatively, either mounting holes 68 or mounting holes 38 are threaded to threadingly engage bolts or fasteners to fasten bracket 60 to ratchet base 32b of mount 30.
(21) If center hole 34 of ratchet base 32b of mount 30 is a threaded hole, then bracket 60 need not be provided, and thus mounting holes 38 of ratchet base 32b need not be provided. Threaded center hole 34 of ratchet base 32b now receives the threaded stud 54 of torque screw 50. In a further alternative embodiment, center hole 34 of ratchet base 32b of mount 30 is a through hole, and a nut is welded to the side of ratchet base 32b opposite to that of ratchets 36. Here again, bracket 60 and mounting holes 38 ratchet base 32b need not be provided. The welded nut instead receives the threaded stud 54 of torque screw 50.
(22) Mount 30 mates with arm 40 as illustrated in
(23) Just like with ratchets 36 or ratchet ring 36 of mount 30, in one embodiment, ratchets 46 or ratchet ring 46 of arm 40 is a separate plastic or metal piece that abuts up against base 42a of arm 40. For example, separate ratchet ring 46 can be a molded plastic piece made of any of the plastics listed above, or of a tougher plastic, such as Teflon. Separate ratchets 36 and 46 can be the same pieces so that they mate together properly. In another embodiment, ratchets 46 or ratchet ring 46 is formed with base 42a and arm 40. For example, ratchet ring 46 can be machined from the same piece of metal with base 42a to form arm 40. Or, ratchet ring 46 can be formed from the same plastic mold as base 42a to form arm 40. Integrally formed ratchets 36 and 46 can have the same size and number of individual ratchet peaks, so that they mate together properly.
(24) Ratchets 36 and 46 provide support assembly 10a with a large amount of adjustability. The user simply turns arm 40 until ratchets 36 and 46 align at an angle, such that top plate 22 is relatively horizontal when the distal end of member 42 abuts the flat screen device.
(25) Member 42b extends from base 42a a distance, such that the total length of arm 40 is longer than the depth of top plate 22 in one embodiment, which is illustrated in
(26) Arm 40, (including member 42b), like mounting flange 32a and ratchet base 32b of mount 30, can be made of a thicker material, e.g., on the order of 0.125 inch (3.2 mm) thick to 0.375 inch (9.5 mm) thick. Member 42b is substantially straight in the illustrated embodiment, but can have a slight taper, such that member 42b narrows as it extends from circular base 42a to its distal end. As illustrated in
(27) Fastener or torque screw 50 includes a knob or handle 52 connected to or formed with a threaded stud 54 discussed above. Handle 52 and stud 54 can each be any of the metals or plastics discussed herein, or combinations thereof. For example, handle can be polycarbonate, while stud 54 can be steel, stainless steel or aluminum. Handle 52 can be knurled or have finger extensions and undulations, as illustrated in
(28)
(29) Referring now to
(30) It should be appreciated that rotating member 42b of arm 40 towards the straight vertical position (270) would lower the rear end 29 of top plate 22 relative to the top of flat screen device 80 in
(31)
(32) Referring now to
(33) Support assembly 10b also includes an alternative mount 130 and an alternative arm 140. Alternative mount 130 includes mounting flange 132a and ratchet base 132b, and includes all of the materials, structure and alternatives for same discussed above for mount 30. Mounting flange 132a defines mounting holes as is the case with mounting holes 38 of mounting flange 32 of mount 30. Ratchet base 132b defines a threaded hole 134 for receiving torque screw or fastener 50. Threaded bracket 60 (
(34) Alternative arm 140 includes a member 142b extending from a circular ratchet base 142a, and includes all of the materials, structure and alternatives for same discussed above for arm 40. Circular base 142a defines a through-hole 144 for accepting threaded stud 54 of torque screw or fastener 50. Spring 75 fits primarily within knob or handle 52 of torque screw 50. Ratchet ring 46 abuts up against the inner surface of circular base 142a and is placed in ratcheted communication with ratchet ring 36 when torque screw 50 is threaded into female threaded hole 134 of mount 130. Ratchet ring 46 can be formed with or be permanently attached to circular base 142a. Ratchet ring 46 is alternatively a separate piece, which can have extensions (not seen in
(35) Member 142b in the illustrated embodiment has a slight taper, such that member 42b narrows as it extends from circular base 142a to its distal end. As illustrated in
(36)
(37) Elongated stand 120 is supported by two or more arms 140 as illustrated in
(38) Referring now to
(39) Support assembly 10d also includes mount 130 and an alternative arm 240. Mount 130 includes mounting flange 132a (not visible in
(40) Alternative arm 240 includes a member 242b extending from a circular ratchet base 242a, and includes all of the materials, structure and alternatives for same discussed above for arms 40 and 140. Circular base 242a defines a through-hole 244 for accepting threaded stud 54 of torque screw or fastener 50. Spring 75 again fits primarily within knob or handle 52 of torque screw 50. Ratchet ring 46 abuts up against the inner surface of circular base 242a and is placed in ratcheted communication with ratchet ring 36 when torque screw 50 is threaded into a cammed lever 250 discussed in more detail below. Ratchet ring 46 can be formed with or be permanently attached to circular base 242a. Ratchet ring 46 is alternatively a separate piece, which can have extensions 47 on the surface opposite its ratcheted surface, that fit into mating grooves or holes 246 formed in circular base 242a, so that separate ratchet ring 46 fits into and cannot rotate relative to circular base 242a of arm 240. Spring 75 again acts as a lock washer to hold torque screw 50 and cammed lever 250 tight together, while ratchet rings 36 and 46 are locked together.
(41) Member 242b can again have a slight taper, such that member 242b narrows as it extends from circular base 242a to its distal end. As illustrated in
(42) The primary difference with support assembly 10d of
(43) The dual lobes of head 252 are cammed such that radius R1 illustrated in
(44) A collar 270 is fitted between arm 240 and head 252 of cammed lever 250. Collar 270 can be made of any material discussed herein, e.g., any of the plastics discussed above, rubber (e.g., silicone), wood, or any of the metals discussed above, such as steel, stainless steel or aluminum. Collar 270 defines a through hole 272 through which threaded stud 54 of torque screw or fastener 50 extends to reach threaded hole 260 of cylindrical nut 258. Collar 270 defines plural notches 274 on its side abutting arm 240, which receive extensions 47 of ratchet ring 46 that extend through mating grooves or holes 246 formed in circular base 242a, so that collar 270 cannot rotate when torque screw or fastener 50 is threaded into threaded hole 260 of cylindrical nut 258 of cammed lever 250.
(45) Collar 270 on its side opposite that of notches 274 defines a curved or rounded surface 276 that matingly receives the dual lobes of head 252. When handle arm 254 of cammed lever 250 is pointing at least substantially vertically downwardly as illustrated in
(46) When the user turns handle arm 254 ninety degrees clockwise in
(47) The user can alternatively or additionally loosen and tighten ratchet rings 36 and 46 via torque screw or fastener 50 of support assembly 10d as has been described herein. Alternatively, cammed lever 250 in essence replaces torque screw or fastener 50. Instead, a bolt or threaded rod with a nut, such as a lock nut, is inserted through aperture 134 of ratchet base 132b of mount 130 (or aperture 34 of ratchet base 32b of mount 30). The bolt or threaded rod extends further through ratchet rings 36 and 46 and arm 40, 140, 240 and into cylindrical nut 258, where the bolt or threaded rod mates threadingly with threaded hole 260 of nut 258. Here, spring 75 may also be omitted. In any of the cammed lever 250 embodiments, collar 270 may be omitted. That is, the cammed dual lobes of head 252 can instead abut directly up against elongated arm 40, 140, 240 or against a flat washer located between the cammed dual lobes of head 252 and arm 40, 140, 240.
(48) It should be understood that while flat screen devices are one primary use for support assemblies 10a to 10d, the support assemblies described herein can be used instead with any relatively thin and flat vertical structure. For example, it is expressly contemplated to use support assemblies 10a to 10c in the workplace with cubicle walls. In many instances, cubicle space is at a premium. Support assemblies 10a to 10c provide the worker with additional room for books, pictures, plants, supplies, etc.
(49) It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
