The present invention generally relates to furniture, such as tables, benches, and chairs, and, in particular, to improved leg assemblies that may be implemented in tables, benches, and other structures.
Many different types of tables are well known and used for a variety of different purposes. For example, conventional tables may include legs that are pivotally attached to a tabletop and the legs may be movable between a use position in which the legs extend outwardly from the tabletop and a storage position in which the legs are folded against the tabletop. Conventional tables with relatively large tabletops and folding legs are often referred to as “banquet tables” and these tables are frequently used in assembly halls, banquet halls, convention centers, hotels, schools, churches, and other locations where large groups of people meet. These types of tables can often be positioned in an assortment of different configurations and used in a variety of settings. When the banquet tables are no longer needed, the table legs can be moved into the storage position and the tables may be more easily moved or stored.
Because most banquet tables have a length between six and ten feet and a width between three and four feet, the required storage area for such tables is quite large even with the legs in the collapsed position. This large storage area may be problematic for businesses or facilities such as hotels, schools, and churches because a considerable number of these tables may have to be stored.
Conventional tables often include tabletops constructed from materials such as wood, particleboard, or metal. Table tops constructed from wood, particleboard or metal, however, are often relatively heavy and this may make the table awkward or difficult to move. Tabletops constructed from wood or metal are also relatively expensive, and these types of tabletops must generally be treated or finished before use. For example, tabletops constructed from wood must generally be sanded and painted, and metal tabletops must be formed into the desired shape and painted. In addition, because these wooden and metal tabletops are relatively heavy, the cost of shipping and transportation of the tables may be increased. The weight of the tabletop may make the tables more difficult to move and store.
In order to decrease the weight of conventional tables, tabletops may be constructed from relatively lightweight materials such as plastic. Disadvantageously, tabletops constructed from lightweight materials may require large reinforcing members or other structural parts such as braces, brackets, support members and the like to strengthen the tabletop. While these additional parts may increase the strength of the tabletop, the added parts may also increase the weight of the table. These additional parts may result in increased manufacturing costs and require additional time to assemble the table. In addition, extra fasteners may be required to assemble and connect these parts to the table, which may require extra time and labor during the manufacturing process. The additional parts and fasteners may further increase the cost of the table and make the table more difficult to manufacture. Moreover, these additional parts and fasteners may have sharp edges that can injure a user's legs or arms.
Conventional tables may include a frame that is connected to the tabletop. The frame may include a pair of side rails connected to sides of the tabletop using fasteners. Multiple fasteners may be required to securely connect the frame to the tabletop and transmit forces applied to the tabletop to the frame. Undesirably, when a relatively large load or force is applied to some known tables, the frame may bend, deform, and/or detach from the tabletop. In addition, the fasteners used to connect the frame to the tabletop may detach or separate from the tabletop. The fasteners may even damage and tear through the tabletop if the load or force exceeds a certain amount. Further, the frames or fasteners of some known tables may collapse in some circumstances.
Additionally, conventional tables may include frames with components that help stabilize the table when the table is being used. These components may extend into the volume or space disposed below the tabletop. The components may also be disposed underneath the tabletop and between the table legs. The components may restrict or limit a user's placement of his or her legs below the tabletop, restrict a number of chairs placed below the tabletop, or restrict a number of users who can comfortably sit at the table.
Support structures, such as leg assemblies, in some conventional tables may be configured to fold relative to a tabletop. For example, these tables may be configured in a storage arrangement in which the support structures are folded against the tabletop and in a use arrangement in which the support structures are arranged substantially normal to the tabletop. In some existing tables, the support mechanisms may be engaged only when a leg assembly is disposed at a ninety-degree (90°) angle relative to the tabletop. In these tables, when a user is configuring the table in use arrangement, the table may be placed on a top surface or side surface of the tabletop such that the leg assembly is accessible. The user may then rotate the leg assembly relative to the tabletop. When the leg assembly is disposed at a ninety-degree (90°) angle relative to the tabletop, the leg assembly may be locked.
In some circumstances, the leg assembly may not be rotated sufficiently relative to the tabletop. For example, a user may erroneously think that the leg assembly is locked, but one or more mechanisms of the leg assembly may not be properly or fully engaged. Insufficient rotation or an improperly locked leg assembly may result in the leg assembly being disposed in an unlocked position. For instance, without the table locked, a force applied to the table or a load placed on the table may cause the leg assembly to rotate relative to the tabletop (e.g., unexpectedly rotate towards the tabletop). Thus, the table or a portion of the table may collapse.
The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments, such as those described. Rather, this background is only provided to illustrate one example technology area where some embodiments described herein may be practiced.
A need therefore exists for a table that eliminates or diminishes the above-described disadvantages and problems.
An aspect is a table that may include two or more components such as a tabletop, a lateral structure, a frame, a leg assembly, and/or a brace member. The tabletop may include a first end, a second end (which may be opposite the first end), and a center portion that may be disposed substantially equidistant from the first end and the second end. The tabletop may include a first distance which may be measured between the first end and the center. The tabletop may be constructed from blow-molded plastic and may be formed as part of a unitary, one-piece construction during a blow-molding process. Additionally, the tabletop may include two tabletop portions, which may have generally the same sizes or different sizes. The two tabletop portions may be configured to be arranged in a storage configuration in which the two tabletop portions are substantially parallel to one another. Also, the two tabletop portions may be arranged in use configuration in which the two tabletop portions are disposed in a generally planar configuration and/or arranged in a plane. One or both of the tabletop portions may be constructed from blow-molded plastic and may be formed as part of the unitary, one-piece construction during a blow-molding process. The frame may be attached to a lower surface of the tabletop. The frame may include a first longitudinal structure that extends along a first side of the tabletop and a second longitudinal structure that extends along a second side of the tabletop. The first longitudinal structure may be separated from the second longitudinal structure by a particular distance such as a lateral frame dimension. The leg assembly may include a support element, a translation mechanism, and a lock device. The support element may include an end structure and the end structure may be attached to an elongated structure. The end structure may be rotatably coupled to the frame. The support element may be rotatable relative to the frame between a first position and a second position, and at least a portion of the support element may be substantially fixed at a position on the frame. The first position may be a stored position in which the leg assembly is positioned adjacent to or at least proximate the lower surface of the tabletop. The second position may be a use configuration in which the leg assembly is disposed substantially perpendicular to the tabletop. The end structure may be rotatably coupled to the frame at a second distance from the first end of the tabletop. Also, the end structure may be rotatably coupled to the frame at a first interface. The elongated structure may include a support shaft. The elongated structure may include a leg configured to be placed on a surface to support the tabletop. The elongated structure may include two legs or two support shafts; and the second distance may be between about one-fifth and one-third of the first distance. The elongated structure may include two support shafts, which may extend from the end structure. The two support shafts may be separated by a shaft support separation distance. The shaft support separation distance may be less than the lateral frame dimension such that the brace member extends in a lateral direction from the frame to one of the two support shafts. The support element may define a receiver on an inner surface. The receiver may be sized and shaped to receive a lock tab that may extend from a lock device when the lock device is in the engaged arrangement. The translation mechanism may be retained relative to the support element and the frame. The translation mechanism may be configured to translate along a portion of the support element as the support element rotates between the first position and the second position. The translation mechanism may include one or more sleeves. The one or more sleeves may at least partially surround the two legs or the two support shafts of the elongated structure. The sleeve may include a leg configured to be placed on a surface to support the tabletop. The leg may define a translation volume in which the support shaft is disposed. Alternatively, the sleeve may include a conduit, which may define a translation volume in which a portion of the elongated structure, such as a leg, is disposed. In detail, when the support element is in the first position, the translation mechanism may be disposed at a first distance from the end structure. Additionally, when the support element is in the second position, the translation mechanism may be disposed at a second distance from the end structure. The first position may be closer to the end structure than the second position. The lateral structure may extend between translation mechanisms. For instance, the lateral structure may extend from a first leg of the two legs to a second leg of the two legs, or from a first support shaft of the two support shafts to a second support shaft of the two support shafts. The lock device may be at least partially disposed in the lateral structure. The lock device may be configurable in an engaged arrangement. In the engaged arrangement, the lock device may fix the translation mechanism to the support element. The lock device may be configurable in a disengaged arrangement. In the disengagement arrangement, the translation mechanism may not be fixed relative to the support element. The lock device may include a compression mechanism. The compression mechanism may be configured to withdraw one or more lock tabs and the lock tabs may extend from the lateral structure into the support element. The brace member may be rotatably attached to the frame and to the translation mechanism. The brace member may be disposed between the frame and an outer portion of the translation mechanism. When the support element is in the first position, the brace member may be positioned at an angle relative to the support element and the frame. When the support element is in the second position, the brace member may be substantially parallel to the frame and the support element. The brace member may be rotatably coupled to the frame at a second interface. The second interface may be disposed between the center of the tabletop and the first interface. The brace member may be positioned between the elongated structure and the first longitudinal structure or between the elongated structure and the second longitudinal structure.
Another aspect is a support assembly and an exemplary embodiment of the support assembly may include a frame, a support element, a translation mechanism, a lock device, a brace member, and/or a lateral structure. The frame may include a first longitudinal structure and a second longitudinal structure. The first longitudinal structure and the second longitudinal structure may be separated by a distance, such as a lateral frame dimension. The support element may be rotatably coupled to the first longitudinal structure and the second longitudinal structure. The support element may be rotatable relative to the frame between a first position and a second position. The support element may be substantially fixed at a position on the frame. The support element may include an end structure and an elongated structure may be attached to the end structure. The elongated structure may include a leg and the leg may be configured to be placed on a surface to support the frame. The elongated structure may include a support shaft. The support element may define a receiver on an inner surface. The receiver may be sized and shaped to receive a lock tab and the lock tab may extend from the lock device when the lock device is configured in the engaged arrangement. The translation mechanism may be configured to translate along a portion of the support element as the support element rotates relative to the frame. The translation mechanism may include a sleeve that at least partially surrounds a structure of the support element. The sleeve may include a leg configured to be placed on a surface to support the tabletop. The leg may define at least a portion of a translation volume in which the support shaft is disposed. The sleeve may alternatively include a conduit and the conduit may define at least a portion of a translation volume in which a portion of the elongated structure such as a leg is disposed. In detail, when the support element is in the first position, the translation mechanism may be disposed a first distance from the end structure. When the support element is in the second position, the translation mechanism may be disposed a second distance from the end structure. The first portion and/or the first distance may be closer to the end structure than the second position and/or the second distance. The lock device may be configurable in an engaged arrangement. In the engaged arrangement, the lock device may fix the translation mechanism relative to the support element. The lock device may be configurable in a disengaged arrangement. In the disengaged arrangement, the lock device may not fix the translation mechanism relative to the support element. The lock device may be biased in the engaged arrangement when the support element is in the first position. The brace member may be disposed between the frame and an outer portion of the translation mechanism. The brace member may be rotatably attached to the frame and to the translation mechanism. The lateral structure may be attached to the translation mechanism. The lock device may be at least partially disposed in the lateral structure. The lock device may include a compression mechanism. The compression mechanism may be configured to withdraw lock tabs that extend from the lateral structure into the support element.
Some benefits of the table, support assembly, and the like may include increasing a volume below the tabletop of a table. For instance, the leg assemblies or the support assemblies may move brace members and other components of the leg assemblies or the support assemblies outside of the volume below the tabletop. For instance, the brace members may be moved to or towards the edges and the lateral element may be moved towards the lower surface of the tabletop. Accordingly, one or more of the components of the leg assemblies and the support assemblies may not interfere with legs of the user, or with chairs or other objects placed below the tabletop.
Another aspect is a table and the table may be comprised of multiple components such as a tabletop, a frame, and/or a leg assembly. The frame may be attached to a lower surface of the tabletop. The leg assembly may include two or more components such as a support element, a translation mechanism, and/or a two-stage lock assembly. The support element may include an end structure attached to an elongated structure. The end structure may be rotatably coupled to the frame such that the support element may be rotatable relative to the frame between a first position and a second position, and the support element may be substantially fixed at a position on the frame. The translation mechanism may be retained relative to the support element and the frame. The translation mechanism may be configured to translate along a portion of the support element as the support element rotates between the first position and the second position. The two-stage lock assembly may include a multi-element lock tab having a body and an end on which a first element and a second element are disposed. The two-stage lock assembly may be configurable in a disengaged configuration in which the translation mechanism is not fixed relative to the support element, a second engaged configuration in which the two-stage lock assembly fixes the translation mechanism to the support element, and a first engaged configuration in which the first element is positioned in a receiver which may be defined in the support element and the second element is not positioned in the receiver. The positioning of the first element in the receiver in the first engaged configuration may prevent an unintentional collapse of the tabletop when the leg and the end structure are not rotated to the second engagement angle. The elongated structure may include a support shaft. The translation mechanism may include a leg that defines a translation volume in which the support shaft is disposed. The leg assembly may be configured such that the disengaged configuration occurs when the leg and the end structure is disposed between an angle of about zero to a first engagement angle at which the first element is introduced to the receiver, the first engaged configuration may occur when the leg and the end structure are positioned in a range from the first engagement angle and a second engagement angle, and the second engaged configuration may occur when the leg and the end structure are positioned at the second engagement angle at which the second element enters the receiver. The first engagement angle may be between about 69 degrees and about 89 degrees. The second engagement angle may be between about 88 degrees and about 95 degrees. The multi-element lock tab may be outwardly biased. For instance, the multi-element lock tab may be outwardly biased such that at when the leg and the end structure are rotated to the first engagement angle, the first element is pushed into the receiver and at the second engagement angle, the second element may be pushed into the receiver. In the first engaged configuration, an opening in the leg may overlap a lower portion of the receiver to enable the first element to move outwardly into the receiver. The opening may include a height that substantially corresponds to a height of the multi-element lock tab. The first element may include a first element height and the multi-element lock tab may include a second height. The first element height may include between about twenty-five percent (25%) and about fifty percent (50%) of the second height. The first element may make up a first portion of the end and the second element may make up a remaining part of the end. The multi-element lock tab may include a top and a bottom. The second element may include a portion of the end between the top and the first element and between the bottom and the first element. The first element may be positioned on a lower portion or an upper portion of the end. A top or a bottom may be sloped towards the first element. The first element may include two protrusive features. The two protrusive features may be positioned at or near a central portion of the body.
Yet another aspect is a two-stage lock assembly. The two-stage lock assembly may be configured to prevent structure collapse because of an insufficiently rotated leg assembly. The two-stage lock assembly may include one or more components such as a multi-element lock tab. The multi-element lock tab may be configured for disposition in a lateral structure of a lock device. The multi-element lock tab may include a body that includes an end on which a first element and a second element may be disposed. The multi-element lock tab may be configurable in a disengaged configuration, a first engaged configuration, and a second engaged configuration. The first element may extend from the body farther than the second element to enable the first element to be introduced into a receiver prior to the second element. The disengaged configuration may occur when the first element and the second element are not positioned in the receiver. The first engaged configuration may occur when the first element is positioned in the receiver and the second element is not positioned in the receiver. The second engaged configuration may occur when the first and the second elements are positioned in the receiver. The first element may include first element height and the multi-element lock tab may include a second height. The first element height may be between about twenty-five percent (25%) and about fifty percent (50%) of the second height. The first element may make up a first portion of the end and the second element may make up a remaining part of the end. The multi-element lock tab may include a top and a bottom. The second element may include a portion of the end disposed between the top and the first element and between the bottom and the first element.
Another aspect is a table that may include a two-stage lock assembly. The two-stage lock assembly may be configured to prevent collapse of the table because of an insufficiently rotated leg assembly. The two-stage lock assembly may include one or more components such as a multi-element lock tab. The multi-element lock tab may be configured for disposition in a lateral structure of a lock device. The multi-element lock tab may include a body that includes an end on which a first element and a second element may be disposed. The multi-element lock tab may be configurable in a disengaged configuration, a first engaged configuration, and a second engaged configuration. The first element may extend from the body farther than the second element to enable the first element to be introduced into a receiver prior to the second element. The disengaged configuration may occur when the first element and the second element are not positioned in the receiver. The first engaged configuration may occur when the first element is positioned in the receiver and the second element is not positioned in the receiver. The second engaged configuration may occur when the first and the second elements are positioned in the receiver. The first element may include first element height and the multi-element lock tab may include a second height. The first element height may be between about twenty-five percent (25%) and about fifty percent (50%) of the second height. The first element may make up a first portion of the end and the second element may make up a remaining part of the end. The multi-element lock tab may include a top and a bottom. The second element may include a portion of the end between the top and the first element and between the bottom and the first element.
Still another aspect is a table that may include a tabletop, a frame attached to the tabletop, and a leg assembly connected to the frame. The leg assembly may include a support element rotatably coupled to the frame, the support element may be rotatable between a first position and a second position; a translation mechanism translating along a portion of the support element as the support element rotates between the first position and the second position; and a two-stage lock assembly including a lock tab with a first element and a second element, the two-stage lock assembly may include a disengaged configuration in which the translation mechanism is not fixed relative to the support element, a first or a second engaged configuration in which the two-stage lock assembly fixes the translation mechanism relative to the support element, and a first or a second engaged configuration in which the first element is positioned in a receiver in the support element and the second element is not positioned in the receiver.
Some benefits of the table, leg assemblies, two-stage lock assembly, and the like may include preventing collapse or reducing a likelihood of collapse of the table in instances in which a leg assembly is not fully extended. For example, in circumstances in which a user insufficiently rotates the leg assembly, a first element of the two-stage lock assembly may engage in a receiver and reduce the likelihood of collapse of the table.
These and other aspects, features and advantages of the present invention will become more fully apparent from the following brief description of the drawings, the drawings, the detailed description of preferred embodiments and appended claims.
The appended drawings contain figures of exemplary embodiments to further illustrate and clarify the above and other aspects, advantages and features of the present invention. It will be appreciated that these drawings depict only exemplary embodiments of the invention and are not intended to limit its scope. Additionally, it will be appreciated that while the drawings may illustrate preferred sizes, scales, relationships and configurations of the invention, the drawings are not intended to limit the scope of the claimed invention. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The present invention is generally directed towards structures such as tables or benches. The principles of the present invention, however, are not limited to tables or benches. It will be understood that, in light of the present disclosure, the exemplary tables disclosed herein can have a variety of shapes, sizes, configurations, and/or arrangements. In addition, while the tables shown in the accompanying figures are banquet or utility tables, it will be appreciated the tables may have any suitable style or configuration such as round, personal, conference, or card tables. Further, the structures disclosed herein may be successfully used in connection with other types of furniture and/or assemblies.
Additionally, to assist in the description of exemplary embodiments of the tables, words such as top, bottom, front, rear, right and left may be used to describe the accompanying figures which may be, but are not necessarily, drawn to scale. It will further be appreciated the tables can be disposed in a variety of desired positions or orientations, and used in numerous locations, environments and arrangements. A detailed description of exemplary embodiments of a table now follows.
Referring to
Accordingly, in at least some of the exemplary embodiments described in the present disclosure, there is no angled support that extends from a center 110 of the tabletop 101 to the leg assemblies 200. Instead, the leg assemblies 200 may include brace members 1700. The brace members 1700 may be coupled between a frame 111 and the leg assemblies 200. The brace members 1700 may be located near outer edges of the tabletop 101. The locations of the brace members 1700 may open up or increase the volume 117 below the tabletop 101.
The leg assemblies 200 may include one or more support elements 112 and one or more translation mechanisms 114. The brace members 1700 may be coupled between the translation mechanism 114 and the frame 111. As the support element 112 transitions between the first position and the second position, the brace members 1700 may rotate and the translation mechanism 114 may translate along a portion of the support element 112. In the use configuration, the leg assembly 200 may be locked, which may secure the leg assemblies 200 by prohibiting the translation mechanism 114 from translating along the support element 112.
In some embodiments, the leg assemblies 200 may include a lock device 400. The lock device 400 may be configurable in an engaged arrangement in which the lock device 400 fixes the translation mechanism 114 to the support element 112, which may lock the leg assemblies 200. Accordingly, in the engaged arrangement the leg assemblies 200 may be fixed such that the translation mechanism 114 cannot translate relative to the support element 112. The lock device 400 may also be configurable in a disengaged arrangement in which the translation mechanism 114 is not fixed relative to the support element 112. In the disengaged arrangement, the leg assemblies 200 may transition from the second position to the first position.
The first table 100 shown in
Referring to
The support assembly 450 may include the frame 111, the support element 112, the translation mechanism 114, the lock device 400, the brace members 1700, and/or the lateral structure 800. The frame 111 may include a first longitudinal structure 201 and a second longitudinal structure 203. The first longitudinal structure 201 may be separated by a lateral frame dimension 205 from the second longitudinal structure 203. The first and second longitudinal structures 201 and 203 may be attached to the lower surface 109 of the tabletop 101. The leg assemblies 200 may be attached to the tabletop 101 indirectly via the first and second longitudinal structures 201 and 203.
The support assembly 450 may include the support element 112 and the support element 112 may be rotatably coupled to the longitudinal structures 201 and 203. In the first leg assembly 200A, the support element 112 may include an end structure 604 and an elongated structure 606. The end structure 604 may be rotatably coupled to the frame 111. For instance, in the embodiment shown in
The translation mechanism 114 may be configured to translate along a portion of the support element 112. For example, as the support element 112 rotates relative to the frame 111, the translation mechanism 114 may translates up or down the support element 112. When the support element 112 has rotated to a first position (such as when the first leg assembly 200A is disposed generally perpendicular to the lower surface 109) the translation mechanism 114 may be fixed relative to the support element 112 by the lock device 400.
The leg assembly 200A may be positioned within the first and second longitudinal structures 201 and 203. For instance, with reference to

The first leg assembly 200A and one or more of the brace members 1700 may function together to enable a transition between the use configuration and the storage configuration, such as the use and storage configurations described above.
With combined reference to
The support element 602 may include an end structure 604 that is attached to one or more elongated structures 606, which are referred to in the embodiment shown in
The legs 606 (as shown in the accompanying figures, the support element 602 may include two legs 606) may be separated by a shaft support separation distance 610. The shaft support separation distance 610 may be less than a lateral frame dimension (e.g., 205), which may be the distance between the first the second longitudinal structures of a frame. Thus, the legs 606 may be positioned within the fame of a table (e.g., tables 100 or 900).
The end structure 604 may be rotatably coupled to the frame. For example, the outer portions 611 (an exemplary embodiment of which is shown in
The elongated structures 604 may define at least a portion of a receiver 613 (an exemplary receiver 613 is shown in
Referring to
The translation mechanism 114 may be retained relative to the support element 112. For instance, the translation mechanism 114 may be slidably retained relative to the support element 112 such that the translation mechanism 114 translates relative to the support element 112 and the translation mechanism 114 may translate in a particular direction. In the exemplary embodiment shown in
The lateral structure 800 may be attached to the translation mechanism 114. For example, in the depicted embodiment, the lateral structure 800 may extend between the translation mechanisms 114. The lock device 400 may be at least partially disposed in the lateral structure 800. The lock device 400 may include a compression mechanism 820. The compression mechanism 820 may include one or more buttons, such as two buttons. The buttons may be disposed in opposing positions, which may create two opposed buttons. A user may actuate the compression mechanism 820 by drawing or pushing the two opposed buttons towards one another. Pressing the opposed buttons of the compression mechanism 820 towards one another may pull lock tabs 803 and 805 towards a center portion of the leg assembly 200. With sufficient force, the lock tabs 803 and 805 may be withdrawn from receivers 613 defined in the support element 112. When the lock tabs 803 and 805 are withdrawn from the receivers 613 and into the lateral structure 800, the translation mechanism 114 may be able to translate relative to the support element 112.
The lock device 400 may be configurable in two arrangements. In an engaged arrangement, an exemplary embodiment is shown in

As shown in
In the translation assembly 114/800, the translation mechanism 114 may be a sleeve or sleeve structure that at least partially surrounds a structure of a support element (e.g., the support element 112 described above). In particular, the translation assembly 114/800 may include conduits 802A and 802B (generally, conduit 802 or conduits 802), which is an example of the translation mechanism 114. Accordingly, the conduits 802 may be retained relative to a support element, a frame, and a brace member. For instance, with reference to
The conduits 802 may define at least a portion of the translation volumes 804. The translation volumes 804 may extend through at least a portion of the entire conduit 802, which may allow the elongated structures (e.g., the legs of the support element) to extend through the conduits 802. The conduits 802 may translate relative to the elongated structures as the support element rotates.
The translation assembly 114/800 may also include the lateral structure 800. The lateral structure 800 may be attached to the conduits 802 at an inner surface of the conduits 802. The lateral structure 800 may be a shell structure in which the lock device 400 is at least partially positioned. The lock device 400 may include a compression mechanism 820. The compression mechanism 820 may include one or more buttons, such as two buttons 815 and 817. The two buttons 815 and 817 may be disposed in an opposed configuration. A user may actuate the compression mechanism 820 by drawing or pushing the two opposed buttons 815 and 817 towards one another. Drawing the opposed buttons 815 and 817 of the compression mechanism 820 towards one another pull lock tabs 803 and 805 towards a center portion of the lateral structure 800. With sufficient force, the lock tabs 803 and 805 may be withdrawn from receivers defined in a support element. When the lock tabs 803 and 805 are withdrawn from the receivers and into the lateral structure 800, the conduits 802 may be able to translate relative to the support element.

For example, the leg assemblies 200B may include a lock device, such as the lock device 400. The lock device 400 may be configurable in an engaged arrangement in which the lock device 400 may fix the translation mechanism 114 to the support element 112. The lock device 400 may be configured in the engaged arrangement when the leg assemblies 200B are in the use configuration. Accordingly, in the engaged arrangement, the leg assemblies 200 may be fixed such that the translation mechanism 114 cannot translate relative to the support element 112. Also, the lock device 400 may be configurable in a disengaged arrangement in which the translation mechanism 114 is not fixed relative to the support element 112. In the disengaged arrangement, the leg assemblies 200 may transition from the second position to the first position or between a use configuration and a storage configuration.

The support assembly 1100 may also be used in connection with other structures or other tables (e.g., banquet tables, round tables, etc.), benches, etc. Some adaptations may be required to the frame 111 to use the support assembly 1100 with the table 100, however, the leg assemblies 200B may operate substantially as described in the following paragraphs.
With reference to
The support assembly 1100 may include the frame 111, the support element 112, the translation mechanism 114, the lock device 400, the brace members 1700, and/or the lateral structure 1300. The frame 111 may include the first longitudinal structure 201 and the second longitudinal structure 203. The first longitudinal structure 201 may be separated by the lateral frame dimension 205 from the second longitudinal structure 203. The leg assemblies 200B may be positioned within the first and second longitudinal structures 201 and 203. For instance, with reference to

The support element 112 may be rotatably coupled to a first longitudinal structure and a second longitudinal structure. For example, the support element 112 may include an end structure 1502 attached to an elongated structure 1504. The end structure 1502 may be rotatably coupled to the first longitudinal structure and the second longitudinal structure such that the leg assembly 200B is rotatable relative to the frame between a first position and a second position. The elongated structure 1504 may extend into the translation mechanism 114, which may be configured to translate along a portion of the support element 112 as the support element 112 rotates relative to the frame.
The translation mechanism 114 may be retained relative to the support element 112. For instance, the translation mechanism 114 may be slidably retained relative to the support element 112 such that the translation mechanism 114 translates relative to the support element 112 in a particular direction. In the exemplary embodiment shown in
The lateral structure 1300 may be attached to the translation mechanism 114. For example, in the depicted embodiment, the lateral structure 1300 may extend from a translation mechanism, such as a first translation mechanism 114 (e.g., a first leg 1600), to another translation mechanism, such as a second translation mechanism 114 (e.g., a second leg 1600).
The lateral structure 1300 may be shell structure, which may be configured to retain the lock device 400. Accordingly, the lock device 400 may be at least partially disposed in the lateral structure 1300. The lock device 400 may include a compression mechanism 1206. The compression mechanism 1206 may include one or more buttons, such as two buttons. The two buttons may be disposed in an opposed configuration. A user may actuate the compression mechanism 1206 by drawing or pushing the two opposed buttons towards one another. The act of drawing the opposed buttons of the compression mechanism 1206 towards one another may pull lock tabs 1201 and 1202 towards a center portion of the leg assembly 200B. With sufficient force, the lock tabs 1201 and 1202 may be withdrawn from receivers 1506, which may be defined in the support element 112. When the lock tabs 1201 and 1202 are withdrawn from the receivers 1506 and into the lateral structure 1300, the translation mechanism 114 may be able to translate relative to the support element 112.
The lock device 400 may be configurable in two arrangements. In an engaged arrangement, which is shown in

The support element 1500 may include an end structure 1502 that is attached to one or more elongated structures 1504, which may be referred to in the embodiment of
The two shaft supports 1504 may be separated by a shaft support separation distance 1510. The shaft support separation distance 1510 may be less than a lateral frame dimension (e.g., 205) between the first and the second longitudinal structures of a frame. Thus, the shaft supports 1504 may be positioned within the fame of a table.
The end structure 1502 may be rotatably coupled to the frame. For example, the outer portions 1508 may be received by the first and the second longitudinal structures of the frame such that the support element 1500 is rotatable relative to the frame between the first position and the second position. The end structure 1502 may be rotatable relative to the frame, but the end structure may be fixed relative to the frame such that the end structure 1502 cannot be displaced.
The elongated structures 1504 may each define a receiver 1506 (an exemplary receiver is shown in
The leg 1600 of
The leg 1600 may also define an opening 1608 that is configured to receive a lock tab from a lock device (e.g., 400). The opening 1608 may be positioned to correspond to a receiver in the support shaft when the leg assembly 200B is in a use position. Thus, the lock tab may be disposed in the opening 1608 and the receiver when the leg assembly 200B is in the use position. The leg 1600 may also define one or more fastener openings 1610. The fastener openings 1610 may be configured to receive a fastener that attaches a brace member to the leg 1600.
The brace member 1700 may include two ends 1702 and 1704, which may define an opening. The ends may be attached to the frame and the translation mechanism, respectively. The ends 1702 and 1704 may be substantially parallel to one another in some embodiments. The ends 1702 and 1704 may be connected by a brace end connector 1706. The brace end connector 1706 may be angled between or otherwise attach the ends 1702 and 1704. The angle of the brace end connector 1706 relative to the ends 1702 and 1704 and length of the brace end connector 1706 may determine a length 1708 (such as shown in
As described above, the leg assemblies 200A and 200B may be configured in a use arrangement when the leg assemblies 200A and 200B are disposed at an angle of about ninety degrees (90°) relative to the tabletop 101 or 901. For example, the use arrangement of the tables 100 and 900 can be seen in
Accordingly, in the following paragraphs, some embodiments of a two-stage lock assembly are described. The two-stage lock assembly includes components that may address an improperly configured table. For instance, the two-stage lock assembly may provide an additional safety feature that may prevent or at least reduces the likelihood that the table 100 or 900 collapses in circumstances in which the leg assemblies 200A or 200B are not fully extended (e.g., to approximately ninety degrees relative to the tabletop). The two-stage lock assembly is described relative to the second leg assembly 200B. It may be understood with the benefit of this disclosure that the two-stage lock assembly may be implemented with the first leg assembly 200A or with other leg assemblies. Additionally, it may be understood that the two-stage lock assembly may be implemented with other tables or structures such as round tables, folding tables, nesting tables, bistro tables, fold-in-half round tables, benches, picnic tables, and the like.
The portion of the second leg assembly 200B shown in
The two-stage lock assembly 1800 may include a multi-element lock tab 1802. The multi-element lock tab 1802 may be disposed in a lateral structure such as the lateral structure 1300 described in
Referring to
In the disengaged configuration 1801A, the first element 1824 may be positioned in the opening 1608 of the leg 1600. An end of the first element 1824 may abut or contact an outer surface of the elongated structure 1504. The outer surface of the elongated structure 1504 may prevent the multi-element lock tab 1802 from moving in an outward direction, which is represented by arrow 1815. For example, the two-stage lock assembly 1800 may be outwardly biased. In these embodiments, the multi-element lock tab 1802 may be biased or pushed by a spring or another biasing mechanism in the outward direction 1815. As the leg 1600 and the end structure 1502 are positioned at an angle between 0 degrees and the first engagement angle, the first element 1824 may be positioned in the opening 1608 and against the outer surface of the elongated structure 1504.
To transition the two-stage lock assembly 1800 to the first engaged configuration 1801B as shown in
Referring to
For example, the leg assembly 200B may be in the first engaged configuration 1801B when the leg 1600 and the end structure 1502 are at an angle between about 70 degrees and about 89 degrees relative to the tabletop 901. In this example, the first engagement angle may be about 70 degrees and the second engagement angle may be about 89 or about 90 degrees. In other embodiments, the first engagement angle may be any angle between about 69 degrees and about 89 degrees and the second engagement angle may be any angle between about 85 degrees and about 95 degrees. In these embodiments, the leg assembly 200B may be in the first engaged configuration 1801B when the leg 1600 and the end structure 1502 are positioned in a range from the first engagement angle and the second engagement angle.
In the first engaged configuration 1801B, the opening 1608 may overlap a lower portion of the receiver 1506. For instance, the leg 1600 may translate towards the end structure 1502 (reducing the distance 1806) such that the opening 1608 becomes aligned with a lower portion with the receiver 1506. Alignment between the opening 1608 and the lower portion of the receiver 1506 may enable the first element 1824 to move outwardly into the receiver 1506. For example, the first element 1824 may transition from abutting the outer surface of the elongated structure 1504 to being positioned in the receiver 1506. When the first element 1824 is positioned in the receiver 1506, the second element 1872 may be positioned in the opening 1608. An end surface of the second element 1872 may abut or contact the outer surface of the elongated structure 1504.
Additionally, in the depicted exemplary embodiment, the opening 1608 may include a height that substantially corresponds to a height 1818 of the multi-element lock tab 1802. Correspondence between the height of the opening 1608 and the height 1818 of the multi-element lock tab 1802 may enable a tight fit, which may assist in stability of the leg assembly 200B.
As mentioned above, the multi-element lock tab 1802 may be outwardly biased. Accordingly, as soon as the leg 1600 and the end structure 1502 are rotated to the first engagement angle, the first element 1824 may be pushed into the receiver 1506 and the second element 1872 may be pushed into the opening 1608.
With the first element 1824 in the receiver 1506, the leg 1600 may be prevented from translating in a direction away from the tabletop 901 and the end structure 1502. Prevention of such translation may further prevent the leg 1600 and the end structure 1502 from rotating relative to the tabletop 901. The first element 1824 may accordingly provide a safety feature when the leg 1600 and the end structure 1502 are not rotated to the second engagement angle.
For example, a user may inadequately rotate the leg 1600 and the end structure 1502. Without the first element 1824, inadequate rotation of the leg 1600 and the end structure 1502 may result in the lock tab not being introduced into the receiver 1506. Accordingly, the leg 1600 may not be locked relative to the end structure 1502, which may enable unintentional translation of the leg 1600 away from the end structure 1502 and collapse of the tabletop 901.
Thus, inclusion of the first element 1824 and positioning the first element 1824 in the receiver 1506 may reduce or prevent an unintentional collapse of the tabletop 901 when the leg 1600 and the end structure 1502 are not rotated to the second engagement angle. From the first engaged configuration 1801B, the second leg assembly 200B may be transitioned to the disengaged configuration 1801A and to the second engaged configuration 1801C. To transition the second leg assembly 200B, the multi-element lock tab 1802 may be removed or retracted from the opening 1608 and the receiver 1506. For instance, with reference to
To transition the two-stage lock assembly 1800 to the second engaged configuration 1801C as shown in
Referring to
In the second engaged configuration 1801C, the opening 1608 may overlap an operable portion of substantially all of the receiver 1506. For instance, the leg 1600 may translate towards the end structure 1502 (which may reduce the distance 1806) such that the opening 1608 becomes aligned with the receiver 1506. Alignment between the opening 1608 and the receiver 1506 may enable the second element 1872 to move outwardly into the receiver 1506. For example, the second element 1872 may transition from abutting the outer surface of the elongated structure 1504 to being positioned in the receiver 1506.
When the leg assembly 200B is in the second engaged configuration 1801C, the multi-element lock tab 1802 may lock the leg 1600 relative to the end structure 1502. For example, the multi-element lock tab 1802 may prevent the leg 1600 from translating relative to the elongated structures 1504, which may prevent the leg 1600 and the end structure 1502 from rotating relative to the tabletop 901. The leg assembly 200B may be transitioned from or to the disengaged configuration 1801A or the first engaged configuration 1801B through operation of the lock device 400.
The first element 1824 may extend from or may make up a part of the end 1930. In the embodiment of
The first element 1824 and the second element 1872 may extend different distances from the end 1930. Extensions of the first element 1824 and the second element 1872 may enable the first element 1824 to be introduced into the receiver 1506 prior to the second element 1872. For example, in
In some embodiments, the top 1934 and/or the bottom 1936 may be sloped. For example, the top 1934 and/or the bottom 1936 may be sloped towards the first element 1824 near the end 1930. In other embodiments, the top 1934 and/or the bottom 1936 may be substantially planar or level. The multi-element lock tab 1802 may be sized relative to the opening 1608 and/or the receiver 1506. For instance, the multi-element lock tab 1802 may include a height 1818 that extends from the top 1934 to the bottom 1936. Similarly, the opening 1608 and the receiver 1506 may include a height 1816. The height 1816 may be substantially equivalent (e.g., within about 8%) the height 1818.
In the depicted embodiment, the opening 1608 and the receiver 1506 may include substantially equivalent heights (e.g., within about 8%) which are represented by height 1816. In some embodiments, a height of the opening 1608 may be greater than a height of the receiver 1506. In these and other embodiments, the height 1816 of the receiver 1506 may correspond to or be substantially equal to the height 1818. Additionally, in some embodiments, the height 1816 may be sized to correspond to a narrowed end of the multi-element lock tab 1802. For instance, the body 1928 may narrow near the end 1930. In these embodiments, the height 1816 may be sized to correspond to a height of the body 1928 near the end 1930.
The particular geometry of the multi-element lock tab 1802 is not meant to be limiting. For instance,
