Storage table system and method

Abstract

A storable table system allows for relatively compact storage of a relatively large sized table. The storable table system uses a tabletop derived from a combination of full corner and half corner sections folded out from two unfolded rectangular center sections. The full corner sections and the half corner sections are coupled to the rectangular center sections with hinges and the rectangular center sections are coupled to each other with linkages. The linkages allow one of the center sections to be folded onto the other center section after the full corner sections and the half corner sections have been folded onto their respective center sections. A table frame supports the tabletop with beam segments that are slidably coupled to one another to expand the width of the table frame for support of the unfolded tabletop.

DETAILED DESCRIPTION OF THE INVENTION

As will be discussed in greater detail herein, a storable table system allows for relatively compact storage of a relatively large sized table. The storable table system uses a tabletop derived from a combination of full corner and half corner sections folded out from two unfolded rectangular center sections.

The full corner sections and the half corner sections are coupled to the rectangular center sections with hinges and the rectangular center sections are coupled to each other with linkages. The linkages allow one of the center sections to be folded onto the other center section after the full corner sections and the half corner sections have been folded onto their respective center sections.

A table frame supports the tabletop with beam segments that are slidably coupled to one another to expand the width of the table frame for support of the unfolded tabletop. The tabletop is pivotably coupled to the table frame to allow the tabletop to rotate approximately 45 degrees between a storage position and a deployed position.

As shown in FIG. 1, a storable table system 100 includes a tabletop 102 and a table frame 104 used to support the tabletop. The tabletop 102 includes two center sections 106 each having a top surface 106T, two full corners 108 each having a top surface 108T, and four half corners 110 each having a top surface 110T. The two center sections 106 each have an exterior side 106E, a center side 106C, and two short sides 106S. The full corners 108 each have a hypotenuse side 108H and the half corners 110 each have a short side 110S.

The storable table system 100 has hinges 112 for coupling of some components. Each of the short sides 110S of the half corners 110 are coupled to a different one of the short sides 106S of the center sections 106 by two of the hinges 112. Each of the hypotenuse sides 108H of the full corners 108 are coupled to a different one of the exterior sides 106E of the center sections 106 by four of the hinges 112. As described further below, the hinges 112 allow each of the half corners 110 and each of the full corners 108 to be folded onto that portion of the center section 106 to which they are coupled.

The center sections 106 have notches 106N and the half corners 110 have notches 110N to provide openings for linkages 120, shown in FIGS. 2 and 3 in a closed linkage-down position, when the storable table system 100 is partially or fully in a stored position further described below. Each of the linkages 120 have two end-links 122 with two mid-links 126 extending therebetween. For each of the linkages 120, the two mid-links 126 are coupled together with pins 128 to form a mid-joint 130. Further, each mid-link 126 is coupled with other of the pins 128 to a different one of the end-links 122 to form an end-joint 132.

The table frame 104 is shown in FIG. 4 without the tabletop 102 connected. The table frame 104 has two post-beam units 140. Each post-beam unit 140 includes two post legs 142 and a support beam 144 running therebetween. The post-beam units 140 are positioned with their two support beams 144 running substantially parallel with each other.

Extending between the two post-beam units 140 are three sliders 146 shown in their extended position in FIG. 4. Each of the sliders 146 has a pair of end segments 148 with one of the end segments of each of the pairs attached to one of the post legs 142 of each of the post-beam units 140. Alternatively, one of each of the pairs of the end segments 148 can be attached to one of the support beams 144. Each of the sliders 146 also has a mid-segment 150 slidably coupled to and extending between the two end segments 148. Based upon the mid-segment 150 of each of the sliders 146 being slidably coupled to the two end segments 148, each of the sliders can be extended in length to expand and contract the size of the table frame 104 along the longitudinal dimension of the slider.

Each of the support beams 144 of the post-beam units 140 have two telescoping extensions 152 that can be pulled out from the support beams to an extended position as shown in FIG. 4 to further support the tabletop 102. A bracket 154 having a slot 156 is attached to the mid-segment 150 of the slider 146 that is centrally positioned between the other two sliders.

A bolt-nut combination 158 slidably and rotatably coupled to the bracket 154 through the slot 156, as shown in FIG. 5, allows the tabletop 102 to be slidably and rotatably coupled to the table frame 104 as further described below. A rotational stop 160 attached to the underside of one corner section 106 of the table top 102 prevents the tabletop from being over-rotated when being rotated from storage to deployment of the system 100. The rotational stop 160 eventually hits one of the support beams 144 when the tabletop 102 is rotated into deployment position as shown in FIG. 5.

In order to store the storable table system 100, a series of actions are taken. First, the two center sections 106 are separated from one another and then rejoined in order to change the linkages 120 from a closed linkage-down position shown in FIG. 2 to a closed linkage-up position shown in FIG. 19. FIGS. 6-9 depict various aspects of the storage table system 100 in an initial stage of this transition between closed linkage-down and closed linkage-up with the two center sections 106 partially separated and the linkages being in a partially open linkage-down position.

FIGS. 10-13 depict various aspects of the storable table system 100 in a interim stage of this transition between closed linkage-down and closed linkage-up with the two center sections 106 fully separated and the linkages being in a fully open linkage-flat position. FIGS. 14-17 depict various aspects of the storage table system 100 in a near final stage of this transition between closed linkage-down and closed linkage-up with the two center sections 106 partially separated and the linkages 120 being in a partially open linkage-up position. FIGS. 18-21 depict various aspects of the storable table system 100 in the final stage of this transition between closed linkage-down and closed linkage-up with the two center sections 106 not separated and the linkages 120 being in a closed linkage-up position.

To further the storage process, the storable table system 100 is converted from a unfolded-corners configuration depicted such as in FIG. 1 to a folded-corners configuration. In the folded-corners configuration, the full corners 108 and the half corners 110 are all folded onto their respective associated portions of the two center sections 106. In an initial stage of this transition from the unfolded-corners configuration to the folded-corners configuration, one of the full corners 108 and one of the half corners 110 are positioned as shown in FIGS. 22 and 23 in the process of being folded onto their respective portions of one of the center sections 106.

FIGS. 24-27 depict various aspects of the storable table system 100 in an interim stage of this transition from the unfolded-corners configuration to folded-corners configuration. One of the full corners 108 and one of the half corners 110 are shown in FIG. 24 as fully folded onto their respective associated portions of one of the center sections 106. As fully folded, the top surface 108T of the folded full corner 108 and the top surface 110T of the folded half corner 110 touch portions of the top surface 106T of one of the center sections 106.

Contrasted views of the linkage 120 in the closed linkage-up position are shown in FIG. 25 and FIG. 26. In FIG. 25, the linkage 120 is shown as one of the linkages on the left half of the system 100 shown in FIG. 24 with the associated half corners 110 shown as unfolded. In FIG. 26, the linkage 120 is shown as one of the linkages on the right half of the system shown in FIG. 24 with an associated one of the half corners 110 shown as folded.

FIGS. 28-29 depict various aspects of the storable table system 100 in the final stage of the folded-corners configuration. All of the full corners 108 and all of the half corners 110 are shown in FIG. 28 as fully folded onto their respective associated portions of the center sections 106. In the folded-corners configuration, the tabletop 102 can be treated in further folding action as if it only had the two center sections 106 that were twice their actual thickness.

The extensions 152 are shown in FIG. 30 and FIG. 31 being in fully retracted positions. The tabletop 102 is shown in FIG. 32 in a storage position having been rotated counter-clockwise relative to the deployment position shown in FIG. 30 by approximately 45 degrees. The difference in rotational position between the deployment position shown in FIG. 31 and the storage position shown in FIG. 33 is also evidenced by the rotational stop 160. From the perspective of the bottom plan views of FIG. 31 and FIG. 33, the rotational stop 160 indicates that the tabletop 102 is rotated clockwise approximately 45 degrees to go from the deployment position to the storage position.

In the storage position shown in FIG. 32, the half corners 110 share a side with two of the sliders 146 since the half corners can be folded over as further discussed below to allow the sliders to be slid into a shortened storage position. To further proceed with configuring the storable table system 100 for storage, in the storage position, the tabletop 102 can be treated as two functional halves 162 coupled together with the linkages 120 with each of these two functional halves having the width, the length, and twice the thickness of one of the center sections 106.

As shown in FIG. 34, FIG. 35, and FIG. 37, one of the functional halves 162 of the tabletop 102 is vertically positioned with the linkages 120 acting as a hinge as further shown in FIG. 35 and FIG. 36. One functional half 162 of the tabletop 102 is shown in FIG. 38, FIG. 39, and FIG. 41 as fully folded over on top of the other functional half of the tabletop in a final position for storage whereas the sliders 146 of the table frame 104 are still extended as being deployed. FIGS. 39 and 40 show the configuration of the linkages 120 for the this final storage position of the tabletop 102.

Finally, the table frame 104 is shown in FIGS. 42-44 with the sliders 146 being slid into a retracted position to complete the storage configuration. FIG. 45 shows the table frame 104 alone with the sliders 146 in the retracted position. Alternative first extensions 164 and second extensions 166 are shown in FIGS. 46-47, which can provide additional stability for supporting the tabletop 102.

From the foregoing it will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention. Accordingly, the invention is not limited except as by the appended claims.
