COLLAPSIBLE RECLINER MECHANISM

TECHNICAL FIELD

The present disclosure generally relates to furniture and, more particularly, recliners including collapsible recliner mechanisms configured to facilitate assembly.

BACKGROUND

Seating furniture is a high sales-volume item in residential retail furniture markets, providing a high revenue source for retail furniture stores. The market for seating furniture is competitive and any improvements in manufacturing resulting in an improved product, better value to the customer, and/or lower manufacturing costs are welcomed by the industry.

In the manufacture of seating furniture items, such as reclining chairs, reclining sofas, or other items including one or more recliner sections, one or more frames including a reclining mechanism, which collectively provide structural support and basic shape of the item. Traditionally, portions of the frame may be constructed of wood materials, plastics, metals, or combinations thereof. For example, the recliner mechanism may include several metal components that are assembled and mechanically coupled to other portions of the frame. With respect to recliners, the incorporation of the recliner mechanism, whether motorized or non-motorized, into the framework of the recliner requires secure structural support of the recliner mechanism above the floor, allowing the recliner mechanism to movably support some or all of the recliner components such as the back rest, the footrest or ottoman, the seat, and the arm rests. The presence of the recliner mechanism and the cooperation of the various parts make assembly of recliners more tedious and challenging than sofas or a chair with no moving components. The frame may be covered by padding or cushioning, such as foam, and then covered with fabric, leather, synthetic fabric, faux leather, microfiber, or other upholstery.

Assembly of furniture frames including recliner mechanisms have long assembly times due to the number of parts must be manually assembled to construct the final furniture item. For example, recliner mechanism may include eight or more components which must be manually mechanically coupled with 14 or more fasteners. As such, there is a need for a simplified method for manufacturing furniture items that reduces labor and material costs while providing a product that provides a sufficient or improved level of support and comfort to the user. Additionally, due to packaging, shape, weight, and/or size of individual recliner mechanism components, automated assembly may be difficult. Any improvements in recliner construction methods that simplify the manufacture and that make the manufacturing less labor intensive and would be welcomed by the furniture industry and result in lower costs to the manufacturers and to the purchasing public.

SUMMARY

The embodiments of the present disclosure include seating furniture including reclining mechanisms for which the number of components that need to be manually assembled is minimized, the assembly is simplified, the assembly time is reduced, the finished product is robust and sturdy, the shipping density of partially assembly recliner mechanisms is increased, or combinations thereof.

In some examples, a recliner mechanism of a recliner may include a first side linkage having a first seat deck link configured to couple to a seat deck of the recliner and a first back rest link configured to couple to a back rest of the recliner, a second side linkage having a second seat deck link configured to couple to the seat deck of the recliner and a second back rest link configured to couple to the back rest of the recliner, and at least one support member having a first end coupled to the first side linkage and a second end coupled to the second side linkage. The first side linkage is movable relative to the second side linkage from a collapsed configuration to an expanded configuration.

In some examples, a recliner mechanism of a recliner may include a first side linkage, and second side linkage, and at least one hinged tube. The first side linkage includes a first seat deck link configured to couple to a seat deck of the recliner and a back rest link extending in a first plane and configured to couple to a back rest of the recliner. The second side linkage includes a second seat deck link configured to couple to the seat deck of the recliner and a second back rest link extending in a second plane substantially parallel to the first plane and configured to couple to the back rest of the recliner. The at least one hinged tube includes a first section having a first end coupled to the first linkage and a second end and a second section having a third end coupled to the second linkage and a fourth end pivotally coupled to the second end of the first section. The recliner mechanism is configured to move between a collapsed configuration and an expanded configuration.

An example method of manufacturing a recliner mechanism may include pivotally coupling a first end of a support member to a first linkage, where the first side linkage includes a first plurality of links substantially extending parallel to a first plane. The method also may include pivotally coupling a second end of the support member to a second side linkage, where the second linkage includes a second plurality of links substantially extending parallel to a second plane. The first plane may be substantially parallel to the second plane. The method also may include moving the recliner mechanism from an expanded configuration toward a collapsed configuration, where a distance D1 between the first plane and the second plane in the expanded configuration is less than a distance D2 between the first plane and the second plane in the collapsed configuration.

An example method of assembling a recliner mechanism that includes a first side linkage having a first plurality of links substantially extending parallel to a first plane, a second side linkage having a second plurality of links substantially extending parallel to a second plane substantially parallel to the first plane, and a support member pivotally coupled at a first end to the first side linkage and pivotally coupled at a send end to the second side linkage, may include positioning the recliner mechanism on a work surface, where the first plane and the second plane are substantially perpendicular to the work surface. The method also may include moving the recliner mechanism from a collapsed configuration toward an expanded configuration, where a distance D1 between the first plane and the second plane in the expanded configuration is less than a distance D2 between the first plane and the second plane in the collapsed configuration. The method also may include securing the recliner mechanism in the expanded configuration.

The above summary is not intended to describe each illustrated embodiment or every implementation of the present disclosure.

DETAILED DESCRIPTION

The present disclosure describes recliner mechanisms for seating furniture such as upholstered recliners. The recliner mechanisms are configured with support members movably coupled to first and second side linkages, which enables the recliner mechanisms to be partially assembled, appropriately configured for packaging and shipping, and more easily reconfigured for final assembly. As such, a feature and advantage of the recliner mechanisms described herein include that select components of the recliner mechanism may be manufactured and at least partially assembled at one advantageous location and then shipped to a final assembly location. Additional features and advantages of the described recliner mechanisms may include, for example, reducing the number of components that need to be manually handled or installed during final assembly, simplifying and reducing the time needed for assembly, increasing the shipping density of partially assembly recliner mechanisms, or combinations thereof.

FIG. 1 is a conceptual diagram illustrating a perspective view of an upholstered recliner 100. Recliner 100 includes a seat 102 with a seat cushion 104, a pair of arm rests 106 and 108, a back rest 110, and a footrest 112. The upholstery of recliner 100 may include, for example, operational cardboard or fiberboard for providing further shape; padding or cushioning, such as load poly, arm fiber, and/or foam; and fabric, leather, synthetic fabric, faux leather, microfiber, or other upholstery or covering materials. Although illustrated as an upholstered recliner, in other examples, recliner 100 may include an unupholstered recliner or a portion of a furniture item having at least one reclining seat, such as a reclining seat of a couch or sectional sofa.

FIG. 2 is a partial exploded view of recliner 100 illustrated in FIG. 1 with the upholstery coverings removed revealing the assembled recliner frame 200 formed of a seat deck 202, a pair of arm rest frames 206 and 208, a back rest frame 210, a footrest frame 212, and recliner mechanism 220.

Each of seat deck 202, arm rest frames 206 and 208, back rest frame 210, and footrest frame 212 may be separately form of any suitable material, such as, for example, wood, plastic, metal, or combinations thereof. In some examples, seat deck 202, arm rest frames 206 and 208, back rest frame 210, and footrest frame 212 may include materials and/or methods of manufacture as described in U.S. patent application Ser. No. 18/193,325, titled “UPHOLSTERED RECLINER INCLUDING MOLDED FURNITURE COMPONENTS,” filed on Mar. 30, 2023, published as US 2023/0232987, the entire contents of which is incorporated by reference herein.

In examples in which one or more of seat deck 202, arm rest frames 206 and 208, back rest frame 210, and footrest frame 212 include wood components, such components can be formed using any suitable wood working techniques and formed of different materials including, by way of example, hardwood, softwood, engineered wood, plywood, or the like. In examples in which one or more of seat deck 202, arm rest frames 206 and 208, back rest frame 210, and footrest frame 212 include plastic components, such components can be formed of by molding methods, such as blow molding (injection blow molding, extrusion blow molding, injection stretch blow molding), including with more than one parison, and can be formed of different materials including, by way of example, polyethylene (PE), such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE), polyvinyl chloride (PVC), polypropylene (PP), nylon, and polyethylene terephthalate (PET), thermoplastic elastomers (TPE), acrylonitrile butadiene styrene (ABS), polyphenylene oxide (PPO), nylon/polyamids (PA), polycarbonate (PC), polyester and copolyester, urethane and polyurethane, and acrylic and polystyrene. In other embodiments, molded components can be formed by differing molding methods, such as injection molding (overmolding, insert molding, cold runner injection molding, hot runner molds) and rotational molding.

Each of seat deck 202, arm rest frames 206 and 208, back rest frame 210, and footrest frame 212 may be configured to mechanically couple with a suitable fastener such as one or more self-tapping bolts or screws, bolts, screws, rivets, or the like to respective portions of recliner mechanism 220, one or more of each other, of combinations thereof. Recliner mechanism 220 may include a pair of side linkages. The pair of side linkages may each include a plurality of links coupled to select links of the plurality of links and/or select components of the recliner.

FIG. 3 is a conceptual diagram illustrating a perspective view of the recliner mechanism 320 of the recliner of FIG. 2. Recliner mechanism 320 generally includes a pair of side linkages 322 and 324 coupled by one or more support members 325. In some examples, the one more support members 325 may include cross tubes 326 and 328, torque tube 330, and drive tube 332. Side linkages 322 and 324, may be mirror images of each other with identical structure and function. As a result, the description provided herein below for side linkage 322 should be assumed to apply also to side linkage 324.

Side linkage 322 generally includes ground-engaging base link 334, front swing link 336, rear swing link 338, seat link 340, lower coordinating linkage 342, ottoman linkage 344, upper coordinating linkage 346, drive linkage 348, and backrest linkage 350. Side linkage 322 defines a plane to which each of the links is generally parallel. Rear swing link 338 is pivotally connected to base link 334 at pivot 352 and to bell crank 354 of lower coordinating linkage 342 at pivot 356. Front swing link 336 is pivotally connected to upper link 358 of upper coordinating linkage 346 at pivot 360. Front swing link 336 is coupled to base link 334 with follower post 362 slidably disposed in slot 364. Side linkage 322 may include additional links operatively coupled to enable selected actuation of recliner mechanism 320, such as described in, for example, U.S. Pat. No. 7,850,232, titled “ZERO CLEARANCE RECLINER MECHANISM,” filed on Jul. 10, 2007, the entire contents of which is incorporated by reference herein.

FIG. 4 is a conceptual diagram illustrating a perspective view of an example cross tube 400. Cross tube 400 may be the same as or substantially similar to cross tubes 326 and 328 of recliner mechanism 320 illustrated in FIG. 3. Cross tube 348 includes a tubular structure 401 extending from proximal end 402 to a distal end 404. Each of proximal end 402 and distal end 404 are configured to mechanically couple to at least one side linkage of recliner mechanism 320. For example, proximal end 402 may define one or more apertures 406A and 406B configured to receive there through a respective fastener 408A and 408B (e.g., self-tapping bolts, bolts, machine screws, or the like) to mechanically couple cross tube 400 to the at least one side linkage of recliner mechanism 320. Similarly, distal end 404 may define one or more apertures 410A and 410B configured to receive there through a respective fastener 412A and 412B.

One or more respective washers (e.g., washers 414A, 414B, 416A, and 416B) may be disposed between cross tube 400 and the at least one side linkage of recliner mechanism 320, and retained by a respective fastener (e.g., fasteners 408A, 408B, 412A, and 412B). In some examples, a respective washer may be configured to facilitate rotational movement of cross tube 400 relative to recliner mechanism 320 about an axis of a respective fastener (e.g., axis 418A, 418B, 420A, and 420B) during assembly of recliner mechanism 320, such as prior to fully seating the respective fastener and/or prior to installation of other fasteners. For example, cross tube 400 may be temporarily mounted to a first side linkage of recliner mechanism 320 by fastener 408A and a second side linkage of recliner mechanism 320 by fastener 412B. When temporarily mounted, fasteners 408A and 412B may not be fully seated to allow cross tube 400 to rotate relative to the respective side linkages of recliner mechanism 320 about each respective axis 418A and 420B. In this way, the respective opposing side linkages of recliner mechanism 320 may be coupled by cross tube 400 and may be movable relative to each other, such as, for example, to enable closer packing of a plurality of recliner mechanisms for packaging and/or shipment of the plurality of recliner mechanisms.

As illustrated in FIG. 4, tubular structure 401 includes tapered portions defining the respective proximal end 402 and distal end 404. The tapered portions may be formed by any suitable technique such as, for example, casting, crushing, forging, machining, stamping, of the like. In other examples, tubular structure 401 may be tubular (i.e., non-tapered) and each respective proximal end 402 and distal end 404 may include an optional respective bracket. For example, the optional respective bracket may be configured to receive at least a portion of tubular structure 401 and define the one or more respective apertures (e.g., 406A and 406B).

In some examples, to further facilitate final assembly, fasteners 408A, 408B, 412A, and 412B may include self-tapping bolts (i.e., thread cutting bolts) which may be at least partially preinstalled or otherwise at least partially seated into respective apertures 406A, 406B, 410A, and 410B. In this way, cross tube 400 with each of fasteners 408A, 408B, 412A, and 412B at least partially preinstalled may be handled as a single component during final assembly. This may simply final assembly and reduce the time required for final assembly compared to an assembly in which cross tube 400 and fasteners 408A, 408B, 412A, and 412B must be individually handled to install fasteners 408A, 408B, 412A, and 412B.

FIG. 5 is a conceptual diagram illustrating a perspective view of a drive tube 500. Drive tube 500 may be the same as or substantially similar to drive tube 332 of recliner mechanism 320 illustrated in FIG. 3. Drive tube 500 includes a tubular structure 501 extending from proximal end 502 to a distal end 504. In some examples, drive tube 500 defines a proximal aperture 506 and a distal aperture 508 configured to mechanically couple to at least one side linkage of recliner mechanism 320. Drive tube 500 may be configured to rotate at least a portion of the at least one side linkage of recliner mechanism 320 to actuate recliner mechanism 320 from a first position to at least a second position.

FIG. 6 is a conceptual diagram illustrating a perspective view of a torque tube 600. Torque tube 600 may be the same as or substantially similar to drive tube 330 of recliner mechanism 320 illustrated in FIG. 3. Torque tube 600 includes a tubular structure 601 extending from proximal end 602 to a distal end 604. Each of proximal end 602 and distal end 604 are configured to mechanically couple to at least one side linkage of recliner mechanism 320. For example, proximal end 602 may define one or more apertures 606A and 606B configured to receive there through a respective fastener 608A and 608B (e.g., self-tapping bolts, bolts, machine screws, or the like) to mechanically couple torque tube 600 to the at least one side linkage of recliner mechanism 320. Similarly, distal end 604 may define one or more apertures 610A and 610B configured to receive there through a respective fastener 612A and 612B. In some examples, fasteners 608A, 608B, 612A, and 612B may include at least partially preinstalled self-tapping bolts.

One or more respective washers (e.g., washers 614A, 614B, 616A, and 616B) may be disposed between torque tube 600 and the at least one side linkage of recliner mechanism 320, and retained by a respective fastener (e.g., fasteners 608A, 608B, 612A, and 612B). In some examples, a respective washer may be configured to facilitate rotational movement of torque tube 600 relative to recliner mechanism 320 about an axis of a respective fastener (e.g., axis 618A, 618B, 620A, and 620B) during assembly of recliner mechanism 320, such as prior to fully seating the respective fastener and/or prior to installation of other fasteners. For example, torque tube 600 may be temporarily mounted to a first side linkage of recliner mechanism 320 by fastener 608A and a second side linkage of recliner mechanism 320 by fastener 612B. When temporarily mounted, fasteners 608A and 612B may not be fully seated to allow torque tube 600 to rotate relative to the respective side linkages of recliner mechanism 320 about each respective axis 618A and 620B. In this way, the respective opposing side linkages of recliner mechanism 320 may be coupled by torque tube 600 and may be movable relative to each other, such as, for example, to enable closer packing of a plurality of recliner mechanisms for packaging and/or shipment of the plurality of recliner mechanisms.

As illustrated in FIG. 6, tubular structure 601 includes tapered portions defining the respective proximal end 602 and distal end 604. The tapered portions may be formed by any suitable technique such as, for example, casting, crushing, forging, machining, stamping, of the like. In other examples, tubular structure 601 may be tubular (i.e., non-tapered) and each respective proximal end 602 and distal end 604 may include an optional respective bracket. For example, the optional respective bracket may be configured to receive at least a portion of tubular structure 601 and define the one or more respective apertures (e.g., 606A and 606B).

FIG. 7 is a partially exploded view of a recliner mechanism 700. Recliner mechanism 700 may be the same as or substantially similar to recliner mechanism 320 illustrated in FIG. 3, except for the differences described herein. For example, recliner mechanism 700 includes a cross tubes 702 and 704, torque tube 706, and drive tube 708 that are configured to coupled first side linkage 710 to a second side linkage 712.

As illustrated in FIG. 7, torque tube 706, drive tube 708, and select cross tube fasteners 714A-714D may be removed from recliner mechanism 700. In this way, similar to the discussion above in reference to FIG. 4, cross tubes 702 and 704 are configured to movably couple first side linkage 710 to second side linkage 712. That is, first side linkage 710 and second side linkage 712 may be actuated, e.g., rotated, about an axis defined by the respective remaining fasteners of cross tubes 702 and 704.

FIG. 7 illustrates recliner mechanism 700 in an expanded configuration. In the expanded configuration a width of recliner mechanism is illustrated as distance D1. Distance D1 may be a maximum width of recliner mechanism 700.

FIGS. 8A and 8B are a perspective view and a front view, respectively, of the recliner mechanism 700 of FIG. 7 in a partially collapsed configuration. By moveably coupling side linkages of the recliner mechanism 700, a plurality of recliner mechanisms maybe more closely packed for shipment and assembly of recliner mechanism 700 may be simpler, faster, require less manual manipulation for assembly, require manual installation of fewer fasteners, or combinations thereof. As illustrated in FIG. 8B, first side linkage 710 is movably coupled to cross tube 702 by fastener 714E and to cross tube 704 by fastener 714F. Second side linkage 712 is similarly movably coupled to cross tube 702 by fastener 714G and to cross tube 704 by fastener 714H. The axes defined by respective fasteners 714E-714H may be substantially parallel such that cross tubes 702 and 704, when coupled to first side linkage 710 and second side linkage 712, may simultaneously rotate about the respective axes defined by fasteners 714E and 714F. As used herein, substantially parallel may include parallel or nearly parallel, such as within about 5-degrees or about 10-degrees of parallel. In this way, first side linkage 710 may be moved in a direction indicated by arrow 716 and, simultaneously or independently, second side linkage 712 may be moved in a direction indicated by arrow 718.

In the partially collapsed configuration, a width of recliner mechanism 700, illustrated by distance D2, may be less than the width in the expanded configuration, D1. In some examples, the partially collapsed configuration of recliner mechanism 700 having width D2 may enable a higher packaging density of a plurality of recliner mechanisms compared to the expanded configuration. That is, a greater number of a plurality of recliner mechanisms in the partially collapsed configuration may be packaged in a predetermined volume compared to a plurality of recliner mechanisms in an expanded configuration.

FIGS. 8C and 8D are a perspective view and a front view, respectively, of the recliner mechanism 700 of FIG. 7 in a fully collapsed configuration. As discussed above in reference to FIGS. 8A and 8B, first side linkage 710 may be moved in a direction indicated by arrow 716 and second side linkage 712 may be moved in a direction indicated by arrow 718, until at least a portion of cross tubes 702 and/or 704 contact or otherwise interfere with a portion of first side linkage 710, second side linkage 712, or both. In some examples, recliner mechanism 700 may be packed for shipment in a configuration that is less than full actuated to reduce or prevent wear at the one or more points of contact or interference of cross tubes 702 and/or 704 with first side linkage 710 and/or second side linkage 712. In other examples, fasteners 714G and/or 714H may be tightened or fully seated in the fully collapsed configuration or less than fully collapsed configuration, e.g., partially collapsed configuration, to reduce or prevent wear caused by movement of first side linkage relative to second side linkage during shipment.

In the fully collapsed configuration, the width of recliner mechanism 700, illustrated by distance D3, may be less than the width in the expanded configuration, D1, and the width in the partially collapsed configuration, D2. In some examples, the fully collapsed configuration of recliner mechanism 700 having width D3 may enable a higher packaging density compared to the expanded configuration or partially collapsed configuration of recliner mechanism. That is, a greater number of a plurality of recliner mechanisms in the fully collapsed configuration may be packaged in a predetermined volume compared to a plurality of recliner mechanisms in an expanded configuration or the partially collapsed configuration.

In some examples, during assembly, recliner mechanism 700 may be removed from a package (i.e., shipping container) in a fully collapsed configuration or a partially collapsed configuration and, subsequently, moved manually, by automated robot, or a combination thereof into the expanded configuration. Once in the expanded configuration, the four fasteners 714A-714D may be installed to retain recliner mechanism in the expanded configuration. In some examples, fasteners 714A-714D may include at least partially preinstalled self-tapping bolts. Additionally, in examples in which fasteners 714E-714H are not fully tightened during shipment, fasteners 714E-714H may be tightened or fully seated. Torque tube 706 and/or drive tube 708 may be installed prior to or after installing and/or tightening fasteners 714A-714H. In some examples, fasteners 714E-714H also may include at least partially preinstalled self-tapping bolts. Once fasteners 714E-714H, torque tube 706, and drive tube 708 are installed, recliner mechanism may be in a final assembly state suitable for receiving other components of an upholstered recliner, such as frame members. Because recliner mechanism 700 is partially assembled in the fully collapsed or partially collapsed configuration, final assembly in the expanded configuration requires installation of fewer fasteners, manipulation of fewer parts, or both thereby making final assembly simpler, faster, and enabling optional automated assembly of at least portion of the recliner mechanism.

Packaging or assembly of a recliner mechanism may be further improved by providing cross tubes, torque tubes, and/or drive tubes that are configured to actuate or collapse, requiring installation of even fewer fasteners, manipulation of even fewer parts, or both.

FIGS. 9A-9G are conceptual diagrams illustrating multiple views of a recliner mechanism 900 including a hinged torque tube 906 and hinged cross tubes 902 and 904. FIGS. 9A-9G illustrate respectively a perspective view, a front view, a back view, a left view, a right view, a top view, and a bottom view of recliner mechanism 900. The hinged tubes may enable recliner mechanism 900 to occupy even less volume in a fully collapse configuration compared to a recliner mechanism in which tubes are not hinged and, when assembling, require installation of even fewer fasteners, require manipulation of even fewer parts, or both.

Recliner mechanism 900 may be the same as or substantially similar to recliner mechanism 700 described above in reference to FIGS. 7-8D, except for the differences described herein. For example, recliner mechanism 900 includes drive tube 908, first side linkage 910, and second side linkage 912, which may be substantially similar to drive tube 708, first side linkage 710, and second side linkage 712 described above. In a fully expanded configuration, recliner mechanism 900 may have a width illustrated by distance D1. Unlike torque tube 706 and cross tubes 702 and 704, hinged torque tube 906 and hinged cross tubes 902 and 904 include at least two sections movably coupled at a hinge or pivot point.

For example, as illustrated in FIG. 9B, torque tube 906 includes a first section 920 and a second section 922 movably coupled to first section 920 at hinge section 924. The ends of first section 920 and second section 922 opposite hinge section 924 may be moveably coupled to the first side linkage 910 and second side linkage 912, respectively. For example, first section 920 is coupled to first side linkage 910 at pivot point 914 and second section 920 is coupled to second side linkage 912 at pivot point 916. Pivot points 914 and 916 may include a mechanical fastener such as a bolt or rivet configured to movably couple first section 920 and second section 922 to respective first and second side linkages 910 and 912.

Hinge section 924 includes a pivot point 926. Pivot point 926 may include a mechanical fastener such as a bolt or rivet configured to movably couple first section 920 to second section 922. In some examples, hinge section also may include a detent section 928. Detent section 928 may be defined by a protrusion defined by first section 920 of torque tube 906 and a corresponding recess defined by second section 922 of cross tube 902. When first section 920 and second section 922 are aligned in a substantially parallel arrangement, i.e., the expanded configuration illustrated in FIG. 9B, at least a portion of the recess of second section 922 may receive therein at least a portion the protrusion of first section 920. In this way, detent section 928 to resist movement of recliner mechanism 900 from the expanded configuration toward a partially collapsed configuration.

In some examples, second section 922 may define a second recess portion configured to receive therein at least a portion the protrusion of first section 920 when first section 920 and second section 922 are in non-parallel arrangement, i.e., a partially collapsed configuration or a fully collapsed configuration. In this way, detent section 928 may be configured to retain recliner mechanism 900 in a partially collapsed configuration or a fully collapsed configuration.

Although illustrated as included detent section 928, in other examples, first section 920 and second section 922 may define respective apertures configured to receive therethrough a bolt, machine screw, or other mechanical fastener configured to secure first section 920 to second section 922 in the expanded configuration. In some examples, the mechanical fastener may include an at least partially preinstalled self-tapping bolt.

In some examples, hinge section 924 also may include a stop tab 930. Stop tab 930 may be configured to reduce or prevent over rotation of first section 920 relative to second section 922 when torque tube 906 is moved from a fully or partially collapsed configuration to the extended configuration. For example, when first section 920 and second section 922 are aligned in a substantially parallel arrangement, i.e., the expanded configuration illustrated in FIG. 9B, at least a portion stop tab 930 may contact or interfere with at least a portion of second section 922. Although illustrated in FIG. 9B as protruding from (e.g., defined by) first section 920, in other examples, stop tab 930 may protrude from second section 922.

When in the expanded configuration, to further secure torque tube 906, fastener 915 may mechanically couple first section 920 to first side linkage 910 and fastener 917 may mechanically couple second section 922 to second side linkage 912. In some examples, fasteners 915 and 917 may include at least partially preinstalled self-tapping bolts.

Torque tube 906 may include any suitable material manufactured by any suitable method. For example, torque tube 906 may include a metal, such as, e.g., a steel alloy, a polymeric material, such as, e.g., a fiber reinforced polymer, or combinations of one or more metals and one or more polymeric materials. In examples in which components of torque tube 906 include a metal, such components may be formed using any suitable metallurgic technique, such as, for example, casting, forging, stamping, subtractive manufacturing, additive manufacturing, or the like. In examples in which components of torque tube 906 include a polymeric, such components may be formed using any suitable technique, such as, for example, injection molding, subtractive manufacturing, additive manufacturing, or the like.

Each of cross tube 902 and 904 or drive tube 908 may be configured substantially the same as or similarly to torque tube 906 described above. In this way, recliner mechanism 900 is configured to be moved from a collapsed configuration to an expanded configuration (or vice versa) with any one of more of torque tube 906, drive tube 908, and cross tubes 902 and 904 moveably coupled to first side linkage 910 and second side linkage 912.

FIGS. 10A-10G are conceptual diagrams illustrating multiple views of a hinged tube 1000 of recliner mechanism 900 illustrated in FIGS. 9A-9G. FIGS. 10A-10G illustrate respectively a perspective view, a front view, a back view, a left view, a right view, a top view, and a bottom view of hinged tube 1000.

Hinged tube 1000 may be the same or substantially similar to any one or more of hinged torque tube 906 and hinged cross tubes 902 and 904. For example, hinged tube 1000 may include a first section 1020 having a pivot point 1014 and configured to receive a fastener 1015, a second section 1022 having a pivot point 1016 and configured to receive a fastener 1017, a hinge section 1024 having a pivot point 1026, a detent 1028, and a stop tab 1030.

FIGS. 11A-11G are a conceptual diagram illustrating multiple views of a recliner mechanism 1100 in a partially collapsed configuration. Recliner mechanism 1100 may be the same as or substantially similar to recliner mechanism 900 described above in reference to FIGS. 9A-9G, except for the differences described herein. For example, recliner mechanism 1100 includes hinged cross tubes 1102 and 1104, hinged torque tube 1106, first side linkage 1110, and second side linkage 1112.

As illustrated in FIGS. 11A and 11B, in the partially collapsed configuration, recliner mechanism 1100 may have a width illustrated by distance D2. In the partially collapsed configuration, a width of recliner mechanism 1100, illustrated by distance D2, may be less than the width in the expanded configuration, D1. In some examples, the partially collapsed configuration of recliner mechanism 1100 having width D2 may enable a higher packaging density of a plurality of recliner mechanisms compared to the expanded configuration. That is, a greater number of a plurality of recliner mechanisms in the partially collapsed configuration may be packaged in a predetermined volume compared to a plurality of recliner mechanisms in an expanded configuration.

Additionally, a height H1 of the partially collapse configuration of recliner mechanism 1100 may be equal to a height of the side linkages. The height H1 may be less than the height of the partially collapsed configuration of recliner mechanism 700 illustrated in FIG. 8B or the fully collapsed configuration of recliner mechanism 700 illustrated in FIG. 8D. In this way, by providing cross tubes, torque tubes, and/or drive tubes that are configured to actuate or collapse, recliner mechanism 1100 may enable a greater packing density compared to recliner mechanism 700.

In some examples, recliner mechanism 1100 may be removed from a package (e.g., shipping container) in a partially collapsed configuration and, subsequently, moved manually, by automated robot, or a combination thereof into the expanded configuration. Because the bottom of both first side linkage 1110 and second side linkage 1112 remain on the same plane, recliner mechanism 1100 may be more stable during manipulation to actuate recliner mechanism 1100 from the partially collapsed configuration to the expanded configuration compared to other packing configurations such as the configuration illustrated in FIGS. 8A-8D. By providing additional stability when unpacking, recliner mechanism 1100 may make final assembly simpler, faster, and enabling optional automated assembly of at least a portion of the recliner mechanism.

FIGS. 12A-12G are conceptual diagrams illustrating multiple views of a hinged tube 1200 of recliner mechanism 1100 illustrated in FIGS. 11A-11G. FIGS. 12A-12G illustrate respectively a perspective view, a front view, a back view, a left view, a right view, a top view, and a bottom view of hinged tube 1200.

Hinged tube 1200 may be the same or substantially similar to any one or more of hinged torque tube 1106 and hinged cross tubes 1102 and 1104. For example, hinged tube 1200 may include a first section 1220 having a pivot point 1214 and configured to receive a fastener 1215, a second section 1222 having a pivot point 1216 and configured to receive a fastener 1217, a hinge section 1224 having a pivot point 1226, a detent 1228, and a stop tab 1230.

FIGS. 13A-13G are a conceptual diagram illustrating multiple views of the recliner mechanism 1300 in a fully collapsed configuration. Recliner mechanism 1300 may be the same as or substantially similar to recliner mechanism 900 and/or 1100 described above in reference to FIGS. 9A-11G, except for the differences described herein. For example, recliner mechanism 1300 includes hinged cross tubes 1302 and 1304, hinged torque tube 1306, first side linkage 1310, and second side linkage 1312.

As illustrated in FIGS. 13A and 13B, in the fully collapsed configuration, recliner mechanism 1300 may have a width illustrated by distance D3. In the fully collapsed configuration, a width of recliner mechanism 1300, illustrated by distance D3, may be less than the width in the expanded configuration, D1, or the partially collapsed configuration, D2. In some examples, the fully collapsed configuration of recliner mechanism 1300 having width D3 may enable a higher packaging density of a plurality of recliner mechanisms compared to the expanded configuration or the partially collapsed configuration. That is, a greater number of a plurality of recliner mechanisms in the partially collapsed configuration may be packaged in a predetermined volume compared to a plurality of recliner mechanisms in an expanded configuration.

Additionally, a height H2 of the fully collapse configuration of recliner mechanism 1100 may be greater than a height of the first and second side linkages 1310 and 1312. The height H1 may be less than the height of the partially collapsed configuration of recliner mechanism 700 illustrated in FIG. 8B or the fully collapsed configuration of recliner mechanism 700 illustrated in FIG. 8D. While height H2 may be greater than height H1, illustrated in FIG. 11B, packaging considerations such as orientation or securement devices or filling within a shipping container may dictate a distance greater than H2 for packaging sufficient to reduce or prevent damage during shipment. Additionally, or alternatively, by protruding beyond a plane P defined by an upper more extend of first and second side linkages 1310 and 1312, cross tube 1302 may protect the upper more extend of first and second side linkages 1310 and 1312 from damage during shipment. For example, an object impinging on a top of a shipping container may first contact cross tube 1302 before contacting the upper more extend of first and second side linkages 1310 and 1312. In some examples, replacement of cross tube 1302 damaged during shipment may be less expensive or faster than replacing one or more links of first and second side linkages 1310 and 1312. In these ways, by providing cross tubes, torque tubes, and/or drive tubes that are configured to actuate or collapse, recliner mechanism 1100 may enable a greater packing density, protection during shipment, or both compared to other recliner mechanisms.

In some examples, recliner mechanism 1300 may be removed from a package (e.g., shipping container) in the fully collapsed configuration and, subsequently, moved manually, by automated robot, or a combination thereof into the expanded configuration. Because the bottom of both first side linkage 1310 and second side linkage 1312 remain on the same plane, recliner mechanism 1300 may be more stable during manipulation to actuate recliner mechanism 1300 from the partially collapsed configuration to the expanded configuration compared to other packing configurations such as the configuration illustrated in FIGS. 8A-8D. By providing additional stability when unpacking, recliner mechanism 1300 may make final assembly simpler, faster, and enabling optional automated assembly of at least a portion of the recliner mechanism.

FIGS. 14A-14G are conceptual diagrams illustrating multiple views of a hinged tube 1400 of recliner mechanism 1300 illustrated in FIGS. 13A-13G. FIGS. 14A-14B illustrate respectively a perspective view, a front view, a back view, a left view, a right view, a top view, and a bottom view of hinged tube 1400.

Hinged tube 1400 may be the same or substantially similar to any one or more of hinged torque tube 1306 and hinged cross tubes 1302 and 1304. For example, hinged tube 1400 may include a first section 1420 having a pivot point 1414 and configured to receive a fastener 1415, a second section 1422 having a pivot point 1416 and configured to receive a fastener 1417, a hinge section 1424 having a pivot point 1426, a detent 1428, and a stop tab 1430.

FIGS. 15A-15G are a conceptual diagram illustrating multiple views of a recliner mechanism including a telescoping torque tube and telescoping cross tubes in an expanded configuration. FIGS. 15A-15G illustrate respectively a perspective view, a front view, a back view, a left view, a right view, a top view, and a bottom view of recliner mechanism 1500. The telescoping tubes may enable recliner mechanism 1500 to occupy even less volume in a fully collapse configuration compared to a recliner mechanism in which tubes are not telescoping and, when assembling, require installation of even fewer fasteners, require manipulation of even fewer parts, or both.

Recliner mechanism 1500 may be the same as or substantially similar to recliner mechanism 700 described above in reference to FIGS. 7-8D, except for the differences described herein. For example, recliner mechanism 1500 includes drive tube 1508 (illustrated as uncoupled from the side linkages for clarity), first side linkage 1510, and second side linkage 1512, which may be substantially similar to drive tube 708, first side linkage 710, and second side linkage 712 described above. In a fully expanded configuration, recliner mechanism 1500 may have a width illustrated by distance D1. Unlike torque tube 706 and cross tubes 702 and 704, telescoping torque tube 1506 and hinged cross tubes 1502 and 1504 include at least two concentric sections movably coupled in a sliding engagement between the collapsed configuration and the expanded configuration.

For example, as illustrated in FIG. 15B, cross tube 1502 includes a first section 1520, a second section 1522, and a third section 1524. Each of first section 1520, second section 1522, and third section 1524 include concentric tubular structures. Second section 1522 having an outer diameter similar to or slightly less than an inner diameter of third section 1524 such that at least a portion of second section 1522 may fit in a sliding engagement within at least a portion of third section 1524. First section 1520 is similarly size to fit in sliding engagement with second section 1522. Although illustrated as including three sections, in other example, cross tube 1502 may include two sections or more than three sections, such as four sections, five section, or more sections. The ends of first section 1520 and third section 1524 opposite second section 1522 may be fixedly or moveably coupled to first side linkage 1510 and second side linkage 1512, respectively.

In examples in which first section 1520 is fixedly coupled to first side linkage 1510 and third section 1524 is fixedly coupled to second side linkage 1512, no additional fasteners may be needed to couple first section 1520 to first side linkage 1510 or third section 1524 to second side linkage 1512 when in the expanded configuration.

In examples in which first section 1520 is moveably coupled to first side linkage 1510 and third section 1524 is moveably coupled to second side linkage 1512, recliner mechanism 1500 may be configured to collapse similar to recliner mechanism 700 as illustrated in FIGS. 8A-8D, except that a height of the collapsed recliner mechanism 1500 may be less than that of collapsed recliner mechanism 700.

Each of first section 1520, second section 1522, and third section 1524 may define structures configured to secure recliner mechanism 1500 in the expanded configuration. For example, as illustrated in FIG. 15B, first section 1520 includes at least one spring pin 1530 configured to engage at least one respective aperture 1532 defined by a portion of second section 1522. Similarly, second section 1522 includes at least one spring pin 1534 configured to engage at least one respective aperture 1536 defined by a portion of third section 1524. In other examples, structures configured to secure recliner mechanism 1500 in the expanded configuration may include one or more apertures configured to receive therethrough a bolt, machine screw, or other mechanism fastener; a spring collar or other clamping device; a recess configured to receive a c-clip or other retention ring; a detent; or the like.

In some examples, first section 1520, second section 1522, and third section 1524 may define structures configured to secure recliner mechanism 1500 in a partially collapsed or fully collapsed configuration. Retaining recliner mechanism 1500 in the partially collapsed or fully collapsed configuration may facilitate shipment or handling of recliner mechanism 1500.

In some examples, first section 1520, second section 1522, and/or third section 1524 may include stop tabs or stop collars configured to prevent adjacent sections from decoupling.

Cross tube 1502 may include any suitable material manufactured by any suitable method. For example, cross tube 1502 may include a metal, such as, e.g., a steel alloy, a polymeric material, such as, e.g., a fiber reinforced polymer, or combinations of one or more metals and one or more polymeric materials. In examples in which components of cross tube 1502 include a metal, such components may be formed using any suitable metallurgic technique, such as, for example, casting, forging, stamping, subtractive manufacturing, additive manufacturing, or the like. In examples in which components of cross tube 1502 include a polymeric, such components may be formed using any suitable technique, such as, for example, injection molding, subtractive manufacturing, additive manufacturing, or the like.

Each of cross tube 1504, torque tube 1506, and drive tube 1508 may be configured substantially the same as or similarly to cross tube 1502 described above. In this way, recliner mechanism 1500 is configured to be moved from a collapsed configuration to an expanded configuration (or vice versa) with any one or more of cross tubes 1502, torque tube 1506, and drive tube 1508 fixedly or moveably coupled to first side linkage 1510 and second side linkage 1512.

FIGS. 16A-16G are a conceptual diagram illustrating multiple views of a recliner mechanism 1600 including a telescoping torque tube 1606 and telescoping cross tubes 1062 and 1604 in a fully collapsed configuration. Recliner mechanism 1600 may be the same as or substantially similar to recliner mechanism 1500 described above in reference to FIGS. 15A-15G, except for the differences described herein. For example, recliner mechanism 1600 includes telescoping cross tubes 1602 and 1604, telescoping torque tube 1606, first side linkage 1610, and second side linkage 1612.

As illustrated in FIGS. 16A and 16B, in the fully collapsed configuration, recliner mechanism 1600 may have a width illustrated by distance D2. In the fully collapsed configuration, a width of recliner mechanism 1600, illustrated by distance D2, may be less than the width in the expanded configuration, D1. In some examples, the fully collapsed configuration of recliner mechanism 1600 having width D2 may enable a higher packaging density of a plurality of recliner mechanisms compared to the expanded configuration. That is, a greater number of a plurality of recliner mechanisms in the partially collapsed configuration may be packaged in a predetermined volume compared to a plurality of recliner mechanisms in an expanded configuration.

In some examples, recliner mechanism 1600 may be removed from a package (e.g., shipping container) in a fully collapsed configuration and, subsequently, moved manually, by automated robot, or a combination thereof into the expanded configuration. Because the bottom of both first side linkage 1610 and second side linkage 1612 remain on the same plane, recliner mechanism 1600 may be more stable during manipulation to actuate recliner mechanism 1600 from the fully collapsed configuration to the expanded configuration compared to other packing configurations such as the configuration illustrated in FIGS. 8A-8D. By providing additional stability when unpacking, recliner mechanism 1600 may make final assembly simpler, faster, and enabling optional automated assembly of at least a portion of the recliner mechanism.

FIG. 17 is a flow diagram illustrating an example technique of manufacturing an expandable recliner mechanism. Although the technique illustrated in FIG. 17 is described in reference to recliner mechanism 900, the technique may be used to form other recliner mechanisms, such as recliner mechanisms 700 or 1500, and the recliner mechanisms described herein may be formed using other techniques.

The technique illustrated in FIG. 17 includes coupling a first end of a support member (e.g., torque tube 906) to first side linkage 910 (1702). For example, torque tube 906 may be pivotally coupled to first side linkage 910 at pivot point 914 by a suitable fastener such as a bolt or rivet. First side linkage 910 includes a first plurality of links substantially extending parallel to a first plane.

The technique illustrated in FIG. 17 also includes coupling a second end of the support member to second side linkage 912 (1704). For example, torque tube 906 may be pivotally coupled to second side linkage 912 at pivot point 916 by a suitable fastener such as a bolt or rivet. Second side linkage 912 includes a second plurality of links substantially extending parallel to a second plane that is substantially parallel to the first plane.

The technique illustrated in FIG. 17 also includes moving recliner mechanism 900 from an expanded configuration toward a collapsed configuration (1706). A distance D1 between the first plane and the second plane in the expanded configuration is less than a distance D2 between the first plane and the second plane in the collapsed configuration. When in the collapse configuration, first plane and second plane may remain substantially parallel.

In some examples, the technique may include pivotally coupling a first section of the support member to a second section of the support member. For example, the technique may include pivotally coupling first section 920 of torque tube 906 to second section 922 at pivot point 926. In this way, first section 920 and second section 922 may define a hinged section 924 that is actuated when recliner mechanism 900 is moved from the expanded configuration toward the collapsed configuration.

In some examples, the technique may include coupling a first section of the support member to a second section of the support member in a sliding engagement. For example, referring to FIG. 15B, the technique may include inserting a first section 1520 of cross tube 1502 into second section 1522 in a concentric arrangement, and inserting second section 1522 into third section 1524 in a concentric arrangement. In this way, first section 1520, second section 1522, and third section 1524 may define concentric tubes configured to nest within each other when recliner mechanism 1500 is moved from the expanded configuration toward the collapsed configuration.

In some examples, the technique also may include forming at least one of a detent or stop tab in a section of the support tube. For example, the technique may include forming on first section 920 and second section 922 respective corresponding detents 928, such that the detents 928 are configured to resist movement of first section 920 and second section 922 from the expended configuration toward the collapsed configuration. Additionally, or alternatively, the technique may include forming on first section 920 stop tab 930 configured to contact at least a portion of second section 922 when in the expanded configuration.

In some examples, the technique also may include at least partially installing one or more self-tapping bolts. In this way, handling of individual bolts during final assembly may be reduce or eliminated.

FIG. 18 is a flow diagram illustrating an example technique of assembling an expandable recliner mechanism. Although the technique illustrated in FIG. 18 is described in reference to recliner mechanism 900, the technique may be used to assemble other recliner mechanisms, such as recliner mechanisms 700 or 1500, and the recliner mechanisms described herein may be assembled using other techniques.

The technique illustrated in FIG. 18 includes positioning recliner mechanism 900 in a collapsed configuration on or near a work surface. The first and second planes defined by the first and second side linkages of recliner mechanism 900 may be substantially perpendicular to the work surface. Positioning recliner mechanism 900 may be performed manually, with the assistance of an operator-controlled machine or robot, or by an automated machine or robot. In some examples, positioning recliner mechanism 900 may include removing recliner mechanism 900 from a shipping container holding a plurality of recliner mechanisms.

The technique illustrated in FIG. 18 also includes moving recliner mechanism 900 from the collapsed configuration toward the expanded configuration. In some examples, moving recliner mechanism 900 may include grasping each of first and second side linkages 910 and 912, and pulling at least one of first and second side linkages 910 and 912. In other example, moving recliner mechanism 900 may include grasping or otherwise fixing one of first and second side linkages 910 and 912 and applying a force to at least a portion of the support member to move the support member toward the expanded configuration.

The technique illustrated in FIG. 18 also includes securing recliner mechanism 900 in the expanded configuration. For example, securing recliner mechanism 900 in the expanded configuration may include installing fasteners 915 and 917 to mechanically lock first section 920 and second section 922 of torque tube 906 to the respective first and second side linkages 910 and 912 in the expanded configuration. Additionally, or alternatively, securing recliner mechanism 900 in the expanded configuration may include installing at least one fastener to mechanically lock first section 920 to second section 922 in the expanded configuration.

In some examples, the technique also may include fully seating one or more at least partially preinstalled self-tapping bolts.
