Detailed Description
The various embodiments shown in the figures and described herein provide a structure and system for making an articulating bed frame structure that allows for a linear manufacturing process with minimal labor and tooling. The frame element is self-warping (self-aligning) for assembly and is adaptable for a range of sizes.
Referring to the drawings, FIG. 1A shows an articulating bed employing the structural frame disclosed herein. The articulating structure 10 has a seating support 12, an upper body support element 14, a thigh support element 16, the upper body support element and the thigh support element being attached to the seating support element by hinges, and a lower leg support element 18 being attached to the thigh support element by hinges. The support elements are shown as being substantially solid, however, a rigid honeycomb material or similar material providing a rigid planar surface may also be employed. The frame 20 supports the hinge structure 10. As shown in fig. 1B, the carriage 22 is engaged to the seating support 12 and carries the hinge structure 10, allowing for a "wall hugging" effect with the upper body support element 14. As the upper body support member 14 is raised from a flat position to a standing position, the carriage 22 travels longitudinally (from the foot to the head).
The frame 20 is formed from extruded beams 24 shown in fig. 2A and 2B. The extruded beam 24, which may be metal or other structural material, and for the embodiments disclosed herein aluminum, incorporates an inner upper flange 26 and an inner lower flange 28 separated by a slot 30 that opens into a support channel 32 having an upper wall 33 and a lower wall 35. The outer upper flange 34 closes the support channel 32 and extends upwardly to an upper catch flange 36. The accessory channel 38 is backed by the inner lower flange 28 and the outer lower flange 40 provides a partial closure of the exterior of the accessory channel 38. Cables for an articulation system actuator, an integrated massage system, a sound or lighting system associated with the bed may be routed through the accessory channel. In an alternative embodiment, the outer lower flange may provide a complete closure of the accessory channel. Lower gripping flange 42 extends from a bottom flange 44 which also forms the bottom wall of accessory channel 38. The support channel lower wall 35 provides an upper limit for the accessory channel 38 for the embodiment shown in the drawings. The lower edges of the inner upper flange 26 and the upper edges of the inner lower flange 28 terminate in upper and lower chute beads 46, 48, respectively, which in the exemplary embodiment define the slot 30. Depending from the bottom flange 44 is a touch flange 50.
Other desired embodiments may employ alternative configurations of the extrusion. Fig. 2C and 2D show a first alternative for use with embodiments that will be described in more detail later, in which extruded beam 24 terminates with an upper wall 33 of support channel 32 and does not incorporate an upper gripping flange. The lower wall 35 extends from an outer upper flange 34 which closes the support channel 32. The lower wall 35 is supported by the inner flange 29. An outer lower flange 41 extends downwardly from the support channel 32 and terminates at a bottom flange 44. There is a lower flange 43 that extends from the bottom flange 44 and a touch flange 50 that overhangs the bottom flange 44 as in the previous embodiment. An accessory channel 39 is provided.
The configuration of extrusion beam 24 set forth with respect to fig. 2A and 2B allows for the creation of saw cuts 52 as shown in fig. 3A for defining the length and width of side members 70 and end members 72 and 72A, 72B of frame 10. As shown in fig. 3B, a saw blade 54 is employed to provide a precision cut to the extrusion beam 24 extending to a line 56 through the upper gripping flange 36, the outer upper flange 34, the support channel upper and lower walls 33, 35, the outer lower flange 40, the lower gripping flange 42, the attachment channel bottom wall 44, and the touch extension flange 50, leaving only the webs of the inner upper and lower flanges 26, 28 intact as the termination of the cut 52. As shown in fig. 4A and 4B, extruded beam 24 may then be bent at each cut to form frame 10, as will be described in more detail below. As can be seen in fig. 4B, the support channel 32 at the interior of the frame 10 is curved with the cut-out location at the attachment channel 38 at the exterior of the frame. The support channels 32 in each element of the frame are accessible from an open end created at a cut for assembly operations, as will be described in more detail below. Similarly, the end of the accessory channel is open.
The carriage 22 supporting the hinge structure 10 described with respect to fig. 1B engages a support element (such as a translational support block 60 shown in detail in fig. 5) guided in the support channel 32. As shown in fig. 6A and 7A, each translational support block 60 has an upper slot 62 and a lower slot 64 adapted to engage and guide on the upper and lower runner beads 46, 48, with an interior portion 66 of the translational support block 60 engaged within the support channel 32. The central aperture 68 receives a shaft extending from the carriage 22. Auxiliary holes 70 may be employed for attachment fasteners. The translating support block 60 is formed of a natural lubricating material such as nylon or teflon to allow easy translation along the runner bead and support channel during operation of the hinge structure 10, during translation of the carriage 22. As shown in fig. 8 and 9, a pair of translating support blocks 60 guided in the support channels 32 of the side members 70 engage the carriage 22 in spaced relation to provide support for the hinge structure 10. In alternative embodiments, the translation blocks may be guided on the bottom 35 of the support channel 32 or the support elements may be wheels 67 or similar structures with shafts 69 from the carriage 22, which may be received within the support channel 32 as shown in fig. 6B to engage and support the carriage for translational movement. An alternative configuration of the extrusion 24 described with respect to fig. 2C and 2D is shown for this alternative embodiment. Fig. 7B shows the resulting support arrangement.
Various hinge mechanisms may be employed with the frame structure in the disclosed embodiments. For additional rigidity and in the form of integrated manufacturing, a head endplate 76, a foot endplate 78, and a central panel 80 are employed as part of the frame 20, as will be described in more detail below. The contact flanges of the extruded beams engage the peripheral edges of the end plates and the side edges of the center plate. As shown in fig. 10A, the actuator and tension or compression elements for the hinge mechanism may be mounted on the plates or may be engaged by a fixed or locking support block 82 that is received in the support channel 32. These lock support blocks incorporate engagement holes 84 to receive shafts to engage the hinge elements and may include securing holes 86. The locking support blocks 82 may be engaged to be secured in predetermined positions in the support channel by cooperatively drilling fasteners through the upper or lower internal flanges 26, 28, wide-head fasteners inserted into the securing holes 86 to engage one or both of the upper and lower internal flanges 26, 28, or by dimpling the back surface of the support channel with a set screw inserted through the securing holes 86, or by creating a hammered dimple in the flange of the support channel to secure the locked support blocks.
As seen in fig. 10B, additional support elements, such as angled support members 88, may be received at predetermined locations in the support channel 32. The angled support member 88 includes a body 90 that is received in the support channel 32 and an angled extension 92 that projects from the slot 30 to provide additional support for a hinged support element, such as the upper body support element 14 in an unhinged position that is flush with the frame 20.
The angled support members are of sufficient length to bridge the coupling between the abutted extruded beam elements, such as the aforementioned end closure elements 72a and 72 b.
In alternative embodiments, adhesives or mechanical fasteners may be employed to secure the backing. As an example of the use of the extrusion 24 described with respect to fig. 2C and 2D, shown in fig. 11C and 11D, the cushion 95 may employ an extruded foam block 97 having a mounting support 99 incorporated therein. The gasket rests on the lower flange 43. The mounting support 99 may then be attached to the extrusion 24 using mechanical fasteners, such as screws 101 extending through the outer flange 34 of the support channel 32. With the second embodiment of the extrusion 24 in which the outer flange 34 terminates at the upper extent of the support channel 32, the padding 95 provides resiliently flexible partitions 103 (best seen in fig. 11D) that extend above the rigid elements of the extrusion to provide anti-pinch protection in the event that the hinge structure can rest on top of the frame in an unhinged position, such as those disclosed in U.S. patent 8,990,983 entitled "bed frame for an adjustment bed" (having the same assignee as the present application).
As shown in fig. 12A and 12B, the completed frame 20 provides an attractive integral component of bedroom furniture. The hinge structure 10 is supported by the frame 20 and, for the embodiment shown, carries all elements that are flush with the frame upper extension recess.
For frame embodiments in which the frame side and end sections are cut as separate components, the frame is easily assembled using corner brackets, as shown in fig. 13A-13C. Fig. 13A shows an assembled frame using the extrusion described with respect to fig. 2C and 2D. As shown, the side member 70 is connected to the end member 72 by a corner bracket 104 as shown in fig. 13B and seen in fig. 11D using fasteners 105 received through holes 107. For the illustrated embodiment, the corner bracket 104 has rounded corners to accommodate the rounded corners on the pad 95. Although the illustrated embodiment places the bracket 104 on the outer wall of the extrusion 24 in the side member 70 and the end member 72, the bracket may be internally received in the channel 32.
The bottom bracket and leg support 106 shown in fig. 13C may be employed to provide additional rigidity to the corners of the assembled side and end members 70, 72 as seen in fig. 13A. Fasteners may be inserted through the lower flange 43 or the bottom flange 44 (as described with respect to fig. 2C and 2D) and the apertures 108 to join the bottom bracket and leg support to the frame extrusion. The frame 20 may then be supported by legs attached to the bottom bracket and leg supports 106.
The embodiment of frame 22 as disclosed provides a highly simplified manufacturing process with minimal tooling, minimal number of specialty parts, and minimal skilled labor requirements. The extruded beam 24 may be received in long lengths or operated directly from the extruder as shown in fig. 3A with beam lengths cut for the desired bed size. The saw cuts 52 are cut for a predetermined length for the side and end members of the frame for the desired bed size. Each beam may then be powder coated and oven cured, or anodized, or otherwise provided with a desired surface treatment in a direct linear process.
The fabrication of frame 20 for the embodiment described with respect to fig. 3A, 3B, 4A and 4B using the saw cut configuration may be accomplished on a single forming tool 110 as shown in fig. 14A. The end block 112, shown in detail in fig. 14B, is placed in a corner position of the tool 110 corresponding to a corner of the finished frame 22. The end block 112 cooperates with a locating plate 114, which is shown in detail in fig. 15A and 15B to receive corresponding locating holes 116 in the head endplate 76 and foot endplate 78. For the exemplary embodiment, the end plates 76, 78 are fabricated from laminate sheets and can be precisely cut to length and width on a CNC saw or mill and the locating holes 116 drilled to mate with locating discs on the end block 112 of the tool 110. As can be seen in fig. 14A and 14B, the end block 112 is mounted to the top plate 118 of the tool 110, and the dowel pin 120 is received in the sizing hole 122. Different bed widths (single, double or large) can be accommodated by positioning the dowels in the sizing holes 122 of the desired width. The upper surface 124 of the end block 112 provides a stable horizontal support for the end plates 76, 78. The precision fastener holes 126 may be drilled as part of the CNC molding process for the end plates 76, 78.
The end plates 76, 78 are mounted on the tool 110 as shown in fig. 16A such that the extrusion 22 is aligned to position the end element 72 with the cutouts 52a and 52b at the corners of the end plate 76. The reach flange 50 presses against the end edge 128 (visible in fig. 15A) of the end plate 76 and fasteners are installed along that edge to engage the bottom flange 44 with the end member. Then, as seen in fig. 16B, the side element 70 may be produced by bending the extrusion 22 by 90 ° at the cuts 52a and 52B. The center plate 80 may be mounted on the center block 130 of the tool 110 prior to bending the side members 70. The touch flanges 50 of the side elements 70 of the extrusion 22 press against the side flanges 132 (visible in fig. 15A) of the end plate 76, of the central plate 80, and of the end plate 78, and fasteners 127 are installed along these edges to engage the end plate to the bottom flange 44. This attachment configuration is shown in detail in fig. 17.
The frame 20 may also be made by cutting the side and end members 70, 72 from the extrusion 24 to length without leaving a web for the bending of the members. The side elements 70 are aligned with the end elements 72 at the corners, the reach flanges 50 (described with respect to fig. 2C and 2D) engage against the end edges of the end plates 76, 78 and the center plate 80 for mounting fasteners 127, and the corner brackets 104 described with respect to fig. 13A and 13B may be mounted to complete the rigid frame 20.
The translating support block 60, the locking support block 82, and the angled support member 88 may then be inserted into the support channel 32 in the frame side element 70. The non-translating block or component may then be fixed at a predetermined position. To complete the assembly with the end or side elements completely separated, the second end element is then mounted and secured. For extrusions having deflectable saw cuts, the frame 20 may then be removed from the tool 110 and the extrusion 22 may then be bent at the cuts 52c and 52d to close the frame, engage the end members 72a and 72b with the end plates 78, press the reach flanges 50 against the end edges 128 of the end plates 78, and install fasteners along the edges to engage the bottom flanges 44 with the bottom members. As previously described, angled support blocks may be employed to provide additional rigidity by engaging across the support channels 32 of the abutted frame end elements 72a and 72 b. The hinge structures 10 and the actuating elements of the carriages 22 can then be mounted in these blocks or on a central or end plate, as appropriate, and the hinge structures are mounted on the carriages and on the actuating elements.
The mattress for the bed may be made from extruded, possibly Expanded Polyethylene (EPE) using a linear process similar to that of a frame extrusion, or similar materials may be provided in long lengths or may be provided in lengths or operated directly from the extruder, operating on beam lengths cut directly from the extruder. The overall length of the gasket may be cut and a cut made to bend the gasket at the frame gasket. As described in the previously cited co-pending application No. 12/942,916 entitled "bed frame for an adjustable bed" of the common assignee hereof, the geometry of the cutouts providing curved curves at the corners may be employed. The fabric may be applied to the EPE foam during the bonding roll or an alternative spray surface treatment may be applied to the foam. The cut foam is then inserted into the gripping flanges 36 and 42 on the extrusion 22. Alternatively, the covered foam may be cut to a length corresponding to the frame side and end members 70, 72 and separately mounted on each member. As shown in fig. 18, the corner completion element 136, which may include a leg of the bed, may then be secured in the corner by inserting the catch flange 138 into the exposed accessory channel or support channel 32. As shown in fig. 11C, the corner finishing element may be a top cap 137 that provides only flange continuity of the support channel around the corner.
Similarly, as shown in fig. 19, a plurality of bed frames 10 may be physically coupled by employing a coupling splice 139 having flange elements 140 that are engaged into the exposed support channels 30 of the end elements 72 of adjacent frames. This allows multiple frames with separate hinge structures to be coupled into a single bed, for example, a large bed with two single bed-sized hinge assemblies and frames. The prior art need for multiple legs as shown in fig. 20 is now eliminated, allowing a large bed to be created by a paired single bed as shown in fig. 21.
The extrusion 22 may additionally include a profiled element to provide a finished surface on a portion or the entire outer surface of the frame. As shown in fig. 22A and 22B, the upper gripping flange 36' may extend from an intermediate point on the outer flange 40, and the completed cassette element 102A or 102B may be included in the extrusion to provide a substantially finished surface for at least a portion of the frame. As shown in fig. 22C or 22D, the relative height of the finished box element and the fabric padded bolster 94 can be adjusted by positioning the upper gripping flange 36' as desired.
As shown in fig. 23, the attachment of a headboard to the bed can also be easily accommodated. The engagement corners 142 are inserted into the open head ends of the support channels 32 in the frame side members 70 and secured using recessed screws or similar means as previously described for the securing members. The mounting plate 144 extends perpendicular to the insertion flange 146 for mounting a headboard.
Having now described in detail various embodiments of the present invention as required by the patent statutes, those skilled in the art will recognize modifications and substitutions to the specific embodiments disclosed herein. Such changes are within the scope and intent of the present invention as defined in the appended claims.
