DETAILED DESCRIPTION
A folding table 10 in accordance with the present disclosure includes a table top 12 and a table top elevator 14 coupled to table top 12 for supporting table top 12 above a ground level as shown in FIG. 1. Table top 12 includes a right-side panel 122 and a left-side panel 124 coupled to right-side panel 122 by a hinge unit 18 (sometimes called a piano hinge 18) for rotation about a pivot axis P between an expanded-use position, shown in FIG. 1, and a collapsed-storage position, shown in FIG. 3, where right-side panel 122 and left-side panel 124 are folded toward one another about the pivot axis P. In some examples, right-side panel 122 and left-side panel 124 are formed by blow-molding a plastic material into the panels 122, 124. In the illustrative example, weld cones 11 are formed into an underside 44 and optionally engaged with a top side 42 of each panel 122, 124 during the blow-molding process.
Table top elevator 14 includes a right-side leg unit 13 coupled to right-side panel 122 of table top 12 and a left-side leg unit 15 coupled to left-side panel 124 as suggested in FIGS. 1 and 2. Right-side panel 122 and a left-side panel 124 of table top 12 each include a top side 42 positioned to support items placed on folding table 10 and an under side 44 as shown in FIG. 2. Right-side leg unit 13 is coupled to under side 44 of right-side panel 122 and left-side leg unit 15 is coupled to under side 44 of left-side panel 124. Right-side leg unit 13 and left-side leg unit 15 each include a table-locker leg 22 (sometimes called active leg 22) and a support leg 24 (sometimes called passive leg 24). Table-locker legs 22 are positioned at opposing corners of table top 12. Similarly, support legs 24 are positioned at opposing corners of table top 12.
Each table-locker leg 22 is pivotable and slidable relative to table top 12 as suggested in FIG. 2. Table-locker legs 22 are configured to move between an unlocked position, as shown in FIG. 4, and a locked position, as shown in FIG. 7. Table-locker legs 22 are configured to block movement of the panels 122, 124 from the expanded-use position to the collapsed-storage position when in the locked position. Table-locker legs 22 are configured to allow movement of the panels 122, 124 of the table top 12 between the collapsed-storage position and the expanded use position when in the unlocked position. Accordingly, table-locker legs 22 provide means for holding the table top 12 in the expanded-use position so that the table top is maintained in the expanded-use position during use of the folding table 10.
Each table-locker leg 22 includes a leg section 21, a pivot section 23 coupled to leg section 21, and a lock section 25 coupled to pivot section 23 as suggested in FIG. 2. Leg section 21 is configured to support table top 12. Pivot section 23 is coupled along an edge of table top 12 and configured to allow rotation of table-locker leg 22 about a locker-leg pivot axis P2 during movement between the unlocked position and the locked position as suggested in FIG. 5. In one example, locker-leg axis P2 is generally perpendicular to pivot axis P.
Lock section 25 extends along the edge of table top 12 and is received in blocker brackets 32, 34 when table-locker leg 22 is in the locked position as suggested in FIG. 8. In the illustrative example, blocker brackets 32, 34 are formed integrally with panels 122, 124 and receive table-locker legs 22 to block movement of table top 12 from the expanded-use position to the collapsed-storage position. In some examples, blocker brackets 32, 34 are separate components coupled to undersides 44 of panels 122, 124.
In the unlocked position, lock section 25 of table-locker leg 22 is positioned under one of panels 122, 124 of table top 12 and to one side of pivot axis P as suggested in FIG. 6. In the locked position, lock section 25 of table-locker leg 22 is positioned under both of panels 122, 124 of table top 12 and across pivot axis P as suggested in FIG. 8. In the illustrative example, an end connector 56 of table-locker leg 22 is received in an end receiver 58 of support leg 24 when table-locker leg 22 is in the locked position as suggested in FIGS. 11 and 13. In some examples, lock section 25 is swedged to form end connector 56. In some examples, end connector 56 and end receiver 58 are positioned to lie substantially within blocker bracket 32 when table-locker leg 22 is in the locked position.
A leg-slider guide 60 is positioned to guide movement of table-locker legs 22 relative to table top 12 as suggested in FIGS. 2 and 14. Leg-slider guide 60 includes a guide track 64 formed through a cover plate 66 (sometimes called bracket 66) coupled to under sides 44 and a wedge 68 coupled to table-locker leg 22 as shown in FIG. 14. In the illustrative example, wedge 68 is diamond shaped with two rounded corners and is configured to travel within guide track 64 to control motion of table-locker leg 22. Guide track 64 includes a pivot portion 63 and a slide portion 65. Pivot portion 63 is configured to allow table-locker legs 22 to pivot relative to table top 12 and block sliding movement while wedge 68 is traveling within pivot portion 63. Slide portion 65 is configured to allow table-locker legs 22 to slide relative to table top 12 and block pivoting movement while wedge 68 is traveling within slide portion 65.
Table-locker leg 22 also includes a position-locator pin 61 for holding table-locker leg 22 in the locked position at the selection of a user as suggested in FIG. 14. In some examples, position-locator pin 61 is a VALCO pin. Position-locator pin 61 engages a pin hole 69 formed through a cover plate 66 coupled to under side 44 to block sliding movement of table-locker leg 22. A pin ramp 67 coupled to cover plate 66 depresses position-locator pin 61 as table-locker leg 22 slides from the unlocked position to the locked position to allow position-locator pin 61 to travel beneath cover plate 66 to pin hole 69. A user disengages position-locator pin 61 from engagement with pin hole 69 by depressing position-locator pin 61 to allow table-locker leg 22 to slide from the locked position to the unlocked position.
Each support leg 24 is pivotable and slidable relative to table top 12 between a support position, associated with the expanded-use position, and a stowed position associated with the collapsed-storage position as suggested in FIGS. 9 and 12. Each support leg includes a leg section 27 and a pivot section 29 coupled to leg section 27. Leg section 27 is configured to support table top 12. Pivot section 29 is coupled along an edge of table top 12 and configured to allow rotation of support leg 24 relative to table top 12 about a support-leg pivot axis P3 during movement between the stowed position and the support position. In on example, support-leg pivot axis P3 is generally perpendicular to the pivot axis P and generally parallel to locker-leg axis P2. In another example, support-leg pivot axis P3 is generally collinear with locker-leg axis P2 as suggested in FIG. 5.
A leg-slider guide 70, similar to leg-slider guide 60, controls movement of support leg 24 at the selection of a user. In the illustrative example, a slide portion of leg-slider guide 70 is shorter than slide portion 65 of leg-slider guide 60. In some examples, support leg 24 also includes a position-locator pin for holding support leg 24 in the support position at the selection of a user.
In the illustrative example, table-locker leg 22 and support leg 24 are L-shaped as shown in FIG. 2. As such, leg sections 21, 27 provide vertical support to table top 12 and pivot sections 23, 29 and lock sections 25 provide horizontal support to table top 12. With end connectors 56 of table-locker legs 22 received in end receivers 58 of support legs 24, leg units 13, 15 provide substantially continuous horizontal support along a length of folding table 10. In some examples, table-locker legs 22 and support legs 24 are formed from bent metal tubing.
Each under side 44 of right-side and left-side panels 122, 124 is formed to include a locker-leg receiver 46 positioned to receive leg section 21 of table-locker leg 22 and a support-leg receiver 48 positioned to receive leg section 27 of support leg 24 as suggested in FIG. 2. Table-locker leg 22 slides relative to table top 12 from the locked position to the unlocked position and leg section 21 pivots relative to table top 12 to be received in locker-leg receiver 46. Support leg 24 slides relative to table top 12 from the support position to the stowed position and leg section leg section 27 pivots relative to table top 12 to be received in support-leg receiver 48.
Hinge unit 18 includes hinge-pin receivers 92 coupled to under sides 44 of right-side and left-side panels 122, 124 and a hinge pin 94 positioned through hinge-pin receivers 92 as suggested in FIG. 2. Hinge-pin receivers 92 of panels 122, 124 are aligned along pivot axis P to allow panels 122, 124 to pivot relative to one another about hinge pin 94. In some examples, hinge pin 94 is a solid pin. In some examples, hinge pin 94 is a tube. In the illustrative example, each of right-side panel 122 and left-side panel 124 includes three hinge-pin receivers 92. Hinge-pin receivers 92 of right-side panel 122 are interlaced with hinge-pin receivers of left-side panel 124. While three hinge-pin receivers are shown for each of panels 122, 124, more or less hinge-pin receivers 92 may be used, and panels 122, 124 may include differing numbers of hinge-pin receivers 92. In some examples, hinge-pin receivers 92 are integrally formed with panels 122, 124.
In the collapsed-storage position, right-side and left-side panels 122, 124 are rotated about pivot axis P such that under sides 44 are in confronting relation as suggested in FIG. 3. Table-locker legs 22 are in the unlocked position and leg sections 21 are positioned in locker-leg receivers 46. Similarly, support legs 24 are in the stowed position and leg sections 27 are positioned in support-leg receivers 48. Table top elevator 14 is trapped between panels 122, 124 when table top 12 is in the collapsed-storage position as suggested in FIG. 3. In the expanded-use position, right-side and left-side panels 122, 124 are rotated about pivot axis P such that right-side and left-side panels 122, 124 are positioned in substantially the same plane as suggested in FIG. 1. Table-locker legs 22 are in the locked position and lock sections 25 extend across pivot axis P to block rotation of panels 122, 124. Similarly, support legs 24 are in the support position.
After unfolding table top 12, a user pivots leg section 21 of table-locker leg 22 relative to table top 12 as shown in FIGS. 4 and 5. A user slides table-locker leg 22 relative to table top 12 such that lock section 25 extends across pivot axis P as shown in FIGS. 7 and 8. A user pivots leg section 27 of support leg 24 relative to table top 12 as shown in FIGS. 9 and 10. A user slides support leg 24 relative to table top 12 such that end connector 56 is received in end receiver 58 as shown in FIGS. 11 and 13. The table-locker legs 22 and support legs 24 of both leg units 13, 15 are moved in this way. A user does the reverse to allow table top 12 to move to the collapsed-storage position.
Another example of a folding table 210 in accordance with the present disclosure is shown in FIG. 15. Folding table 210 includes a table top 212 and a table top elevator 214 coupled to table top 212 for supporting table top 212 above a ground level. Table top 212 includes a right-side panel 282 and a left-side panel 284 coupled to right-side panel 282 by a hinge unit 218 (sometimes called a piano hinge 218) for rotation about a pivot axis P between an expanded-use position and a collapsed-storage position where right-side panel 282 and left-side panel 284 are folded toward one another about the pivot axis P. In some examples, right-side panel 282 and left-side panel 284 are formed by blow-molding a plastic material into the panels 282, 284. In some examples, weld cones 211, illustratively shown as squares in phantom in FIG. 15, are formed into an underside 244 and optionally engaged with a top side 242 of each panel 282, 284 during the blow-molding process.
Table top elevator 214 includes a right-side leg unit 213 coupled to right-side panel 282 of table top 212 and a left-side leg unit 215 coupled to left-side panel 284 as suggested in FIG. 15. Right-side panel 282 and a left-side panel 284 of table top 212 each include a top side 242 positioned to support items placed on folding table 210 and an under side 244. Right-side leg unit 213 is coupled to under side 244 of right-side panel 282 and left-side leg unit 215 is coupled to under side 244 of left-side panel 284. Right-side leg unit 213 and left-side leg unit 215 each include a table-locker leg 222 (sometimes called active leg 222) and a support leg 224 (sometimes called passive leg 224). Table-locker legs 222 are positioned at opposing corners of table top 212. Similarly, support legs 224 are positioned at opposing corners of table top 212.
Each table-locker leg 222 is pivotable and slidable relative to table top 212 as suggested in FIG. 15. Table-locker legs 222 are configured to move between a locked position, as shown in FIG. 15, and an unlocked position. Table-locker legs 222 are configured to block movement of the panels 282, 284 from the expanded-use position to the collapsed-storage position when in the locked position. Table-locker legs 222 are configured to allow movement of the panels 282, 284 of the table top 212 between the collapsed-storage position and the expanded use position when in the unlocked position. Accordingly, table-locker legs 222 provide means for holding the table top 212 in the expanded-use position so that the table top is maintained in the expanded-use position during use of the folding table 210.
Each table-locker leg 222 includes a leg section 221, a pivot section 223 coupled to leg section 221, and a lock section 225 coupled to pivot section 223 as suggested in FIG. 15. Leg section 221 is configured to support table top 212. Pivot section 223 is coupled along an edge of table top 212 and configured to allow rotation of table-locker leg 222. Lock section 225 extends along the edge of table top 212 and is received in blocker brackets 232, 234 when table-locker leg 222 is in the locked position. Blocker brackets 232, 234 are coupled to undersides 244 of panels 282, 284 and receive table-locker legs 222 to block movement of table top 212 from the expanded-use position to the collapsed-storage position. In some examples, blocker brackets 232, 234 are integral with panels 282, 284.
In the unlocked position, lock section 225 of table-locker leg 222 is positioned under one of panels 282, 284 of table top 212 and to one side of pivot axis P. In the locked position, lock section 225 of table-locker leg 222 is positioned under both of panels 282, 284 of table top 212 and across pivot axis P as suggested in FIG. 18. In the illustrative example, lock section 225 is received between blocker brackets 232, 234 and table top 212 when table-locker leg 222 is in the locked position. An end connector 256 of table-locker leg 222 is received in an end receiver 258 of support leg 224 when table-locker leg 222 is in the locked position. In some examples, lock section 25 is swedged to form end connector 56.
A leg-slider guide 260 is positioned to guide movement of table-locker legs 222 relative to table top 212 as suggested in FIGS. 15 and 16. Leg-slider guide 260 includes a guide track 264 formed through a cover plate 266 (sometimes called bracket 266) coupled to under sides 244 and a slide pin 268 coupled to table-locker leg 222 as shown in FIG. 16.

Each support leg 224 also includes a lock pin 278 coupled to pivot section 229 and positioned to engage a pin hole 279 formed through guide plate 276 to block rotation of support leg 224 from the support position to the stowed position at the selection of a user. In some examples, lock pin 278 is a VALCO pin. A user disengages lock pin 278 from pin hole 279 by depressing lock pin 278 to allow support leg 224 to rotate from the support position to the stowed position.
In the illustrative example, table-locker leg 222 and support leg 224 are L-shaped as shown in FIG. 15. As such, leg sections 221, 227 provide vertical support to table top 212 and pivot sections 223, 229 and lock sections 225 provide horizontal support to table top 212. With end connectors 256 of table-locker legs 222 received in end receivers 258 of support legs 224, leg units 213, 215 provide substantially continuous horizontal support along a length of folding table 210. In some examples, table-locker legs 222 and support legs 224 are formed from bent metal tubing.
Each under side 244 of right-side and left-side panels 282, 284 is formed to include a locker-leg receiver 246 positioned to receive leg section 221 of table-locker leg 222 and a support-leg receiver 248 positioned to receive leg section 227 of support leg 224 as suggested in FIG. 15. Table-locker leg 222 slides relative to table top 212 from the locked position to the unlocked position and leg section 221 pivots relative to table top 212 to be received in locker-leg receiver 246. Support leg 224 pivots from the support position to the stowed position such that leg section 227 is received in support-leg receiver 248.
Hinge unit 218 includes hinge-pin receivers 292 coupled to under sides 244 of right-side and left-side panels 282, 284 and a hinge pin 294 positioned through hinge-pin receivers 292 as suggested in FIG. 15. Hinge-pin receivers 292 of panels 282, 284 are aligned along pivot axis P to allow panels 282, 284 to pivot relative to one another about hinge pin 294. In some examples, hinge pin 294 is a solid pin. In some examples, hinge pin 294 is a tube. In the illustrative example, right-side panel 282 includes three hinge-pin receivers 292 and left-side panel 284 includes two hinge-pin receivers 292 positioned between the hinge-pin receivers 292 of right-side panel 282. Hinge-pin receivers 292 of right-side panel 282 are interlaced with hinge-pin receivers of left-side panel 284. More or less hinge-pin receivers 292 may be used, and panels 282, 284 may include the same number of hinge-pin receivers 292. In some examples, hinge-pin receivers 292 are integrally formed with panels 282, 284.
In the collapsed-storage position, right-side and left-side panels 282, 284 are rotated about pivot axis P such that under sides 244 are in confronting relation. Table-locker legs 222 are in the unlocked position and leg sections 221 are positioned in locker-leg receivers 246. Similarly, support legs 224 are in the stowed position and leg sections 227 are positioned in support-leg receivers 248. Table top elevator 214 is trapped between panels 282, 284 when table top 212 is in the collapsed-storage position. In the expanded-use position, right-side and left-side panels 282, 284 are rotated about pivot axis P such that right-side and left-side panels 282, 284 are positioned in substantially the same plane. Table-locker legs 222 are in the locked position and lock sections 225 extend across pivot axis P to block rotation of panels 282, 284. Similarly, support legs 224 are in the support position.
After unfolding table top 212, a user pivots leg section 221 of table-locker leg 222 relative to table top 212. A user slides table-locker leg 222 relative to table top 212 such that lock section 225 extends across pivot axis P and end connector 256 is received in end receiver 258. A user pivots leg section 227 of support leg 224 relative to table top 212. The table-locker legs 222 and support legs 224 of both leg units 213, 215 are moved in this way. A user does the reverse to allow table top 212 to move to the collapsed-storage position.
Another example of a folding table 310 in accordance with the present disclosure is shown in FIG. 19. Folding table 310 is similar to folding table 210 of FIGS. 15-18 with one difference being the form of hinge unit 318. As such, similar numbering in the 300 series are used to describe common features unless specifically contradicted below.
In the illustrative example, hinge unit 318 includes a hinge pin 394 positioned between fingers 392 of right-side panel 382 and fingers 396 of left-side panel 384 as shown in FIGS. 20-22. Hinge pin 394 includes a shaft 395 and a head 393 coupled to shaft 395. Shaft 395 extends between fingers 392, 396 and hinge pin 394 is held in place with a cap 391 that couples to an opposing end of shaft 395 from head 393.
Some fingers 392 extend from top side 342 of right-side panel 382 toward left-side panel 384 and arc downwardly toward under side 344 as shown in FIGS. 20-22. Other fingers 392 extend from under side 344 of right-side panel 382 toward left-side panel 384 and arc upwardly toward top side 342. Fingers 396 are arranged similarly to fingers 392. Fingers 392, 396 may be formed as part of a blow-molding process of right-side and left-side panels 382, 384. Although eight fingers 392 and nine fingers 396 are shown, more or less fingers 392, 396 may be used.
Fingers 392 are offset from fingers 396 such that fingers 392 are positioned between fingers 396 when right-side panel 382 is aligned with left-side panel 384 as shown in FIG. 21. Hinge pin 394 is positioned to extend across table top 312 and between fingers 392, 396 such that shaft 395 of hinge pin 394 is trapped between fingers 392, 396 to couple right-side panel 382 with left-side panel 384. Fingers 392, 396 align along a pivot axis P to allow panels 382, 384 of table top 312 to pivot about hinge pin 394 between an expanded-use position, shown in FIG. 19, and a collapsed-storage position.
In illustrative examples, hinge unit 18 may include opposing cylindrical features molded into the blow molded table top 12. The cylindrical features, when aligned with each other, create a piano type hinge held together with a pin running through holes in the cylinders. Hinge unit 18 creates a strong center across folding table 10.
In illustrative examples, an active leg 22 rotates upward relative to the table top 12 and then slides across the middle of the table top 12 to lock folding table 10 in an open position. A passive leg 24 rotates upward relative to the table top 12 and locks in place with a VALCO pin 78. A swedged tube 56 slides into an opposing tube 58 for continuous support along the table top 12.
In illustrative examples, a pin 268 coming off of a tube 223 engages with a track 264 in a bracket 266 to guide the active leg 222 into position.
In illustrative examples, a hinge 318 may be formed without additional processing of panels 382, 384 of a table top 312.
A method of using a folding table in accordance with the present disclosure includes several steps. The method begins with a pivoting step in which a first panel of a table top pivots relative to a second panel of the table top such that the first and second panels are substantially aligned in the same plane. The method proceeds to a moving step in which the table-locker legs of a table top elevator are moved from an unlocked position extending along one of the first and second panels to a locked position extending away from one of the first and second panels. The method then proceeds to another moving step in which support legs of the table top elevator are moved from a stowed position extending along one of the first and second panels to a support position extending away from one of the first and second panels such that the support legs cooperate with the table-locker legs to support the table top above a ground level.
The first moving step includes a pivoting step in which a leg section of each table-locker leg pivots about a locker-leg pivot axis P2 in a direction D6 relative to the table top as shown in FIGS. 4 and 5. The first moving step further includes a sliding step in which a lock section of each table-locker leg slides along locker-leg pivot axis P2 in a direction D7 relative to the table top such that the lock section extends under both the first and second panel of the table top to engage with an opposing one of the support legs to block rotation of the first and second panels relative to one another.
The second moving step includes a pivoting step in which a leg section of each support leg pivots about a support-leg pivot axis P3 in a direction D8 relative to the table top. The second moving step further includes a sliding step in which a pivot section of each support leg slides along support-leg pivot axis P3 in a direction D9 relative to the table top.
The method further includes an engaging step. During the engaging step, a lock pin coupled to the support leg engages with a pin hole coupled to the table top to block pivoting movement of the support leg relative to the table top when the support leg is in the support position.
The method further includes a disengaging step. During the disengaging step, the lock pin disengages from the pin hole in response to application of a force F2 to allow pivoting movement of the support leg about support-leg pivot axis P3 in a direction D4 relative to the table top and the support leg moves from the support position to the stowed position.
In another example, during the disengaging step the lock pin disengages from the pin hole in response to application of force F2 to allow sliding movement of the support leg along support leg pivot axis P3 away from the hinge unit in direction D5 followed by pivoting movement of the support leg about support-leg pivot axis P3 in a direction D4 relative to the table top. As a result, the support leg moves from the support position to the stowed position.
The method further includes another engaging step. During the engaging step, a position-locator pin coupled to the table-locker leg engages with a pin hole coupled to the table top to block sliding movement of the table-locker leg relative to the table top when the table-locker leg is in the locked position.
The method further includes another disengaging step. During the subsequent disengaging step, the position-locator pin disengages from the pin hole to allow sliding movement of the table-locker leg in response to application of a force F1. The table-locker leg also moves from the locked position to the unlocked position to allow the first and second panels of the table top to pivot relative to one another about axis P in a direction D1. The first or second panel pivot relative to the other one of the first and second panel such that under sides of the first and second panels are in confronting relation.
The moving the table-locker legs step includes a sliding step. During the sliding step, the lock section of each table-locker leg slides along locker-leg axis P2 in a direction D2 away from the hinge unit relative to the table top such that the lock section extends under one of the first and second panel of the table top to allow rotation of the first and second panel relative to one another. The moving the table-locker legs further includes a pivoting step. During the pivoting step, the leg section of each table-locker leg pivots about the locker-leg pivot axis P2 relative to the table top in a direction D3 to a position extending along one of the first and second panels.
