The present application relates generally to a table, and in particular to a table having a flip top and to various latch mechanisms, user interfaces and accessories associated with the flip top table.
Tables may be configured with flip tops, which are pivotable to an upright stowed position so as to allow for the tables to be more easily stored and transported. In some situations, the flip top and actuating mechanism may introduce various pinch points. Moreover, the mechanisms may be relatively complex and difficult to manufacture and assemble. Over time, the mechanisms may wear or become loose.
In addition, flip top tables often are configured with a pair of leg assemblies, with each leg assembly having a latching mechanism engaged with the rotating table top. In many embodiments, it may be difficult to coordinate the release of both mechanisms such that the table top may be rotated.
The present invention is defined by the following claims, and nothing in this section should be considered to be a limitation on those claims.
In one aspect, one embodiment of a flip top table includes a leg assembly supporting an axle defining a rotation axis extending in a longitudinal direction. A strike plate is non-rotatably secured to the axle, with the strike plate having first and second circumferentially spaced and radially extending stop surfaces. A worksurface is rotatably supported on the axle and includes first and second circumferentially spaced stop surfaces. The worksurface is rotatable about the rotation axis between a use position and a stowed position, wherein the first stop surface of the worksurface engages the first stop surface of the strike plate when the worksurface is in the use position, and wherein the second stop surface of the worksurface engages the second stop surface of the strike plate when the worksurface is in the stowed position. A latch assembly is coupled to and rotatable with the worksurface between the use and stowed positions. The latch assembly includes a lock bolt moveable in the longitudinal direction between a disengaged position, wherein the lock bolt is longitudinally displaced from the strike plate, and an engaged position, wherein the lock bolt engages the second stop surface of the strike plate when the worksurface is in the use position. In one embodiment the table may include a pair of leg assemblies and latch assemblies. In one embodiment, the lock bolt may include a tapered latch surface. In addition, at least one of the first stop surfaces of the strike plate and/or the worksurface may be circumferentially adjustable.
In another aspect, one embodiment of an actuation mechanism includes a housing defining a guide. A lever is pivotally mounted to the housing about a first axis. The lever is pivotable between first and second positions. A slider is pivotally coupled to the lever about a second axis spaced from the first axis. The slider is translatably moveable in the guide between first and second positions as the lever is pivoted between the first and second positions. First and second cables have ends coupled to the slider at spaced apart locations. The ends of the first and second cables are moved equidistance as the lever is pivoted from the first position to the second position. The ends of the first and second cables are moveable in the track relative to the slider as the lever is pivoted from the second position to the first position.
In another aspect, one embodiment of a method for rotating a flip top table includes positioning the worksurface in a use position, wherein the first stop surface of the worksurface engages the first stop surface of the strike plate and wherein the lock bolt engages the second stop surface of the strike plate, moving the lock bolt in the longitudinal direction and thereby disengaging the lock bolt from the second stop surface of the strike plate, and rotating the worksurface from the use position to a stowed position and engaging the second stop surface of strike plate with the second stop surface of the worksurface.
In yet another aspect, one embodiment of a method of simultaneous dual actuation includes pivoting a lever about a first axis between first and second positions, pivoting a slider relative to the lever, translating the slider along a linear path between first and second positions as the lever is pivoted between the first and second positions, and moving first and second cables having ends coupled to the slider at spaced apart locations, wherein the ends of the first and second cables are moved equidistance as the lever is pivoted from the first position to the second position. The method further includes pivoting the lever from the second position to the first position and maintaining the position of the first and second cables while moving the slider relative to the ends of the first and second cables as the lever is pivoted from the second position to the first position.
In yet another aspect, a flip top table includes a leg assembly, a worksurface having a top and bottom surface and a storage hook. The worksurface is rotatably supported by the leg assembly and is rotatable between a horizontal use position and an upright stowed position. The storage hook includes a base coupled to the bottom surface of the worksurface and a hook portion pivotally coupled to the base. A panel is supported by the hook portion, wherein the hook portion and panel are pivotable relative to the base and worksurface between a first position, wherein the panel is positioned transverse to the worksurface when the worksurface is in the use position, and a second position, wherein the panel is positioned substantially parallel to the worksurface when the worksurface is in the stowed position.
In yet another aspect, a method of supporting a panel on a flip top table includes rotating a worksurface relative to a leg assembly between a horizontal use position and an upright stowed position, supporting a panel on a hook portion pivotally coupled to a bottom of the worksurface, wherein the panel extends transverse to the worksurface when the worksurface is in the use position, and rotating the panel and hook portion relative to the worksurface as the worksurface is rotated to the stowed position, wherein the panel extends parallel to the worksurface when the worksurface is in the stowed position.
A table kit includes a worksurface and a leg adapter coupled to the worksurface. The leg adapter has a bottom surface, a pair of laterally spaced bosses extending downwardly from the bottom surface, a pair of laterally spaced through openings formed in the bosses, and a central opening positioned between the pair of through openings. A first leg includes a pair of tubes shaped to receive the bosses. A pair of first fasteners is dimensioned to extend through the through openings and threadably engage the pair of tubes respectively. A second leg has a top end shaped to receive the bosses. A second fastener is adapted to be coupled to the second leg and the adapter at the central opening.
In yet another aspect, one embodiment of a flip top table includes a first leg assembly and a second leg assembly longitudinally spaced from the first leg assembly. A cross bar extends between and is connected to the first and second leg assemblies. A worksurface is rotatably supported by the first and second leg assemblies. A shroud is coupled to the worksurface and extends between the first and second leg assemblies. The shroud at least partially encircles the cross bar, with the worksurface and shroud being rotatable relative to the cross bar and capable of transferring a load from the worksurface to the cross bar.
The various embodiments of the flip top table, actuation mechanism and methods provide significant advantages over other flip top tables and actuation mechanisms. For example and without limitation, the table is configured without any pinch points. Moreover, the latching interface is self-adjusting over time, thereby making the system long lived and robust. In addition, the actuation mechanism, and user interface in particular, leverages the pivoting action of a lever while allowing for simultaneous and equidistant movement of the actuation cables. The hook and panel also provide a convenient way to store panels on a flip top table. In various embodiments, the panels may function as a privacy panel when disposed under the worksurface, or may be repositioned as a display panel. In addition, the leg adapter provides a modular system configured to support a variety of differently configured legs, thereby allowing the end user to customize the appearance of the table.
The foregoing paragraphs have been provided by way of general introduction, and are not intended to limit the scope of the following claims. The various preferred embodiments, together with further advantages, will be best understood by reference to the following detailed description taken in conjunction with the accompanying drawings.
It should be understood that the term “plurality,” as used herein, means two or more. The term “longitudinal,” as used herein means of or relating to a length or lengthwise direction 2, for example a direction running from one end of a worksurface to another end, and vice versa, or running along a length of a support leg. The term “lateral,” as used herein, means situated on, directed toward or running in a front-to-back direction 4 of the worksurface or leg. The term “coupled” means connected to or engaged with whether directly or indirectly, for example with an intervening member, and does not require the engagement to be fixed or permanent, although it may be fixed or permanent. The terms “first,” “second,” and so on, as used herein are not meant to be assigned to a particular component so designated, but rather are simply referring to such components in the numerical order as addressed, meaning that a component designated as “first” may later be a “second” such component, depending on the order in which it is referred. It should also be understood that designation of “first” and “second” does not necessarily mean that the two components or values so designated are different, meaning for example a first direction may be the same as a second direction, with each simply being applicable to different components. The terms “upper,” “lower,” “rear,” “front,” “fore,” “aft,” “vertical,” “horizontal,” “right,” “left,” and variations or derivatives thereof, refer to the orientations of the exemplary table as shown in
As referred to herein, the phrase “pinch points” are defined as a mechanical hazard, based upon guidance from the U.S. Federal Regulations for consumer products (CPSC 16 CFR Ch. II), industry standards (ANSI/BIFMA, UL) and European Norms (EN), with a clearance between adjustable surfaces and adjacent surfaces being less than 1.0 inches (25 mm), and with clearance between all moving components (other than adjustable surfaces) being greater than 0.190 inches (5 mm) or less than 1.0 inches (25 mm). Accordingly, when pinch points are referred to herein as being “avoided,” “eliminated,” or some other equivalent qualifier, it means any gaps or clearances between the noted structures fall outside of these defined ranges, whether less than or greater than the noted dimensions.

The leg assemblies 24, 26 may be configured in different modules, with a modular leg adapter 16 suitable for interfacing with the leg modules. In this way, a table kit may be provided, allowing the end user to select from a menu of different leg assemblies, which may vary in appearance, finish and cost.
In one embodiment, shown in
Referring to
As noted above, the adapter 16 may be modular, meaning it is configured to interface with both the tubular and cast legs 18, 26. The adapter may be made out of metal, for example aluminum, or hard plastic. The outer surface or profile of an adapter housing 44 may be flush with, or match, the outer surface or profile of the legs 26, 28, so as to provide a continuous and smooth transition between the legs and adapter, thereby providing an appearance of a single component. In one embodiment, the adapter housing 44 having a bottom surface 46 with a pair of bosses 48 extending downwardly from the bottom surface. The bosses may be configured as insert portions, or posts. The housing defines a cavity 50 with a pair of recesses 52 formed in an upper portion thereof. Through holes 54, defined in part by the recesses, extend through a floor 56 of the housing, the bottom surface 46, and the bosses 48. The bosses 48 have outer bearing surfaces 58, which are curved or otherwise shaped to mate with an inner surface 60, 62 of the tube uprights 8, 8′, 28. The bosses may be open along an inner side 64 as shown in
As shown in
During assembly, the tube uprights 6 of leg assembly 24 are inserted over the bosses 48, with the outer bearing surfaces 58 of the bosses mating with the inner surface 60 of the tubes. Because the bosses 48 are spaced apart, they are able to receive the pair of tubes. A pair of fasteners 76 is inserted through the through holes 54 and into threadable engagement with the nuts 22. The cover 66 may then be secured over the cavity as shown in
If the other leg assembly 26 is being used, the bosses 48 are inserted into a top portion of the leg defining a single tube having a single opening 78, again with the outer bearing surfaces mating with the inner surface of the tube. The opening 78 is elongated (e.g., obround, oval or defining a non-circular ellipse. In this way, the adapter provides for either a pair of upright tubes, or a single upright tube, to be fitted over the same pair of bosses. A fastener 38 is inserted through the central through opening 74, through the opening 40 in the shelf 36 and is engaged by a fastener 42 bearing against the shelf. The fasteners 38, 42 may tightened to put the fastener 38 in tension and thereby clamp the leg 24, 26 to the adapter. The cover 66, if desired, is secured over the cavity to cover the openings 40, 54.
During assembly, or in assembling a kit (e.g., at the manufacturer or distributer), the installer or assembler selects one of the legs 24, 26 and corresponding fasteners 76, 38 and includes them in a kit for packaging and shipping, and/or selects them from inventor and couples the selected combination on the adapter. The kit, including the adapter, one or both legs and one or both fastener selections, may be assembled and used with fixed tables as well as the flip top table disclosed herein, or other types of structures supported by legs, including for example and without limitation, other types of furniture including body supporting structures, desks, and/or storage, or various types of machinery.

The leg subassembly includes a cross bar 94, which extends longitudinally between and is non-rotatably fixed to longitudinally spaced first and second leg assemblies. The cross bar may be made of metal, such as steel or aluminum, for example as an extrusion. In one embodiment, a plug or chassis adapter 96 is fixed to the end of the cross bar, for example by welding. The plug or chassis may also be made of metal, such as steel. The cross bar 94, plug 96 and leg adapter 16 have outer surfaces 98 that are similarly dimensioned to provide a uniform, continuous surface therebetween as shown in
A strike plate 102 is non-rotatably fixed to the end of the axle, meaning the strike plate does not rotate about the pivot axis 84. The strike plate 102 has first and second stop surfaces 104, 106 circumferentially spaced around, and extending radially from, the pivot axis 84, defined by the axle 86. The strike plate may be made of metal, such as steel.
Now referring to the worksurface assembly, a housing 108 has a pair of flanges 110 and laterally extending arms 112 that are secured to a bottom 114 of the worksurface 150 with fasteners 116. The housing may alternatively, or additionally, be secured with adhesives or other suitable devices. The axle 86 extends through a face 118 of the housing, which housing defines first and second stop surfaces 120, 122 circumferentially spaced around, and extending radially from, the pivot axis 84. The stop surface 120 of the housing engages the stop surface 106 of the strike plate 102 when the worksurface is rotated about the rotation axis to a use position, shown in

The end cap 152 is positioned at an inner end of the housing. The end cap also has a curved bottom surface 153 that mates with the outer surface of the cross bar 94. An actuator plate 154, or strap, is slidably supported by the end cap 152. The plate 154 includes an arm portion 156 having an end that engages an end 158 of a cable 160, which slides in a cable housing 356. The plate is translatable in the longitudinal direction 2. An opposite end 162 of the plate is coupled to the lock bolt, for example at opening 166 with a pin 164 or PEM stud.
In an alternative embodiment, shown in
A cover 168 is secured over and covers the strike plate 102. A bushing 170 is disposed between the cover and the end of the axle 86 to support the axle on the cover. In addition, a bushing 172 is non-rotatably disposed over an intermediate portion of the axle, with the housing 108 rotating about the bushing and axis. The cover may be made of metal or plastic. The cover, end cap, skid plate and housing eliminate any pinch points between the leg assembly, worksurface and cross bar, and also eliminate or avoid any pinch points created by the lock bolt and strike plate.
Referring to another embodiment of a latch mechanism, shown in
The end 184 of the lock member and the engagement surface 176 are each configured with a tapered surface, so as to maintain a tight engagement even if worn, as well as to define a load path therebetween. A hard stop 186, configured as a pin moving within a slot 188 in one embodiment, limits movement of the two components in either pivot direction. The lock member 180, through the engagement surface, applies a continuous load against the hard stop as shown in
When the lock member 180 is released from the locked position, e.g., by bending, the lock member slides along the peripheral edge of the stop member until an opening 190 or notch in the spring is engaged by the hook member 178 formed on the stop member. The hook member 178 engages the opening 190 to hold the lock member, and associated work surface, in a stored position.
The latch mechanism, including the lock member, may be contained within a housing 192, which envelops the stop member, thereby reducing and/or eliminating pinch points and potential tampering. The housing and latch mechanism are relatively compact and easily assembled.
Referring to another embodiment of a latch mechanism shown in
The end 284 of the lock member and the surface 276 are each configured with a tapered surface, so as to maintain a tight engagement even if worn, as well as to define a load path therebetween. The lock member is contained within a housing 292, which envelops the stop member, thereby reducing and/or eliminating pinch points and potential tampering. The housing and lock member are relatively compact and easily assembled. A release/blocker 294 is used to actuate the lock member, as well as provide a secondary lock. The blocker is actuated by an actuator 296, such as a cable or rod, which passes through a recess 298 formed in the top of the housing. The release, when actuated, bends or presses the lock member out of engagement. The blocker 294 also engages a detent 295 in the stop member to lock the worksurface in an upright, stored position.

The side walls 424, 426 provide a transition fit, which vertically aligns each of the intermediate section 202 and/or end sections 152′ at four locations at each interface with the linear section 270, as the upper surface of the horizontal portion 422 is engaged by the lips 408, 410 as shown in
The ends of the intermediate section and end sections each have a single channel opening 430 through an end wall, as shown for example in
In one embodiment shown in
The user interface includes a housing 212 secured to the bottom of the worksurface, for example with fasteners 204. A lever 214, having a grippable cover 216 on at least one side, is pivotally mounted to the housing about a first axis 218 with a pivot member 330, such as a pin. A handle portion 222 of the lever extends outwardly from the housing, where it can be grasped by a user.
A slider 226 is pivotally secured to the lever with a pin about a second axis 229 spaced apart from the first axis 218 and positioned between the handle portion 222 and the first axis 218 so as to maximize the leverage applied by the user. The slider 226 is linearly movable within a longitudinal track 228 defined by the housing. The slider includes an elongated slot 230, or cam surface, extending laterally. A pivot pin 232, defining the second axis, extends through the slot and couples the slider to the lever. The slider includes a pair of couplers 237 engaging the ends of the cables 236. In one embodiment, shown in
In an alternative embodiment, shown in
Referring to
In operation, and to move the worksurface to a stowed position, wherein the worksurface is upright, or substantially vertical, the user grasps the handle of the lever 222 and rotates the lever 214 about the first pivot axis 218 as shown in
The user may thereafter move the lever 222 back to the original position. However, since the lock bolt 128 is blocked by the strike plate 102 from moving back into the cavity 126 (see
When the worksurface is returned to the use position, the biasing member 132 automatically biases the lock bolt 128 back to the engaged position, with the attendant movement of the actuator plate 154 drawing the cable ends 236 along the tracks 234 of the slider.

A storage hook 308 includes a base 312 that is coupled to the bottom surface 114 of the worksurface, for example with a pair of fasteners 310. The storage hook may be made, for example, of metal or plastic. The base has a pair of spaced apart lugs 314 defining a pivot axis 316. A hook portion 318 has a body 320 pivotally connected to the lugs and a pair of spaced apart hooks 322. The space (G) between the hooks is sufficiently dimensioned to allow a user to insert their hand between the hooks and grasp the handle of the panel. The hooks 322 are also dimensioned and spaced such that the hooks may be inserted into the opening 304 of the panel. The hooks each include a bottom shelf 324 and an upturned portion 326. The shelf 324 may be wide enough to accommodate a plurality of panels.
In operation, one or more panels 300 are disposed on the hooks, which extend through the opening 304, with the handle resting on the bottom shelf 324. The upturned portion 326, or protuberance, prevents the panel from sliding off of the shelf 324. The panels 300 may be disposed on the hooks 322 when the worksurface is in either the use or stowed position.
The hook portion 320 and panel 300 disposed thereon are pivotable relative to the base 312 and worksurface 150 between a first position, wherein the panel 300 is positioned transverse to the worksurface 150, for example when the worksurface is in the use position, and a second position, wherein the panel 300 is positioned substantially parallel to the worksurface 150, for example when the worksurface is in the stowed position. It should be understood that the second positions may be other than a parallel orientation, with the angle between the panel and the worksurface simply changing between the first and second positions. The weight of the panel 300, applied to the hook portion 322, causes the hook portion 322 to automatically rotate between the first and second positions as the worksurface 150 is rotated between the use and stowed positions, without the need for any auxiliary biasing member. In the first position, the panel 300 serves as a privacy screen beneath the worksurface as shown in
Although the present invention has been described with reference to preferred embodiments, those skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. As such, it is intended that the foregoing detailed description be regarded as illustrative rather than limiting and that it is the appended claims, including all equivalents thereof, which are intended to define the scope of the invention.
