DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 and 8, there are the examples of the present invention related with a linked structure for foldable table, which both comprise a main frame (10), legs (20), props (30), connecting plate 1 (40) and connecting plate 2 (50).
Referring to FIGS. 1 through 7, they are examples of the present invention, wherein the main frame (10) includes a long-shaped plate body (11) which connects table plates (60) with flexible wire on each side of the plate body (11). Each concave body (12) and supporting leg (14) is set under each end of the plate body (11). As shown in FIGS. 1, 2, 6 and 7, the drop leaf (60) can be multi-plate type or entire-plate type, yet the whole appearance is still a rectangular solid with long sides and wide brims. On each side under the drop leaf (60) there are tenon holes (61) set equidistantly. As shown in FIGS. 1 and 6, the tenon holes (61) which under the drop leaf (60) are marked for being understood easily, a connecting unit locking hole (121) is set on each bottom end of the concave body (12), and a connecting unit (13) is set inside the hollow space of the concave body (12). Inside the connecting unit (13) there is a receiving concave (131), and a concave body locking hole (132) which set on each narrow side end of the connecting unit (13) can be locked with the connecting unit locking hole (121) of the concave body (12) correspondingly, and the connecting unit (13) can be rotated through the connecting unit locking hole (121) as a fulcrum. Leg fitting holes (133) are set on the bottom end and prop fitting holes (134) are set on top end on the wide side of the connecting unit (13). The supporting leg (14) can be two-stage folded, which connects with connecting plate 2 (50). When the present invention is in unfolded position, the supporting leg (14) can support and make the whole structure stable.
Referring to FIG. 3, the leg (20) is set in the receiving concave (131) of the connecting unit (13), and a connecting unit fitting hole (21) on top end of the leg (20) can be locked with the leg fitting hole (133) on the connecting unit (13) correspondingly and rotate the leg (20) with the leg fitting hole (133) as a fulcrum. A connecting plate fitting hole (22) is set on the leg (20).
Referring to FIG. 3, the prop (30) is set on the connecting unit (13), and the length of the prop (30) is the same as the wide brim of the drop leaf (60). The front end of the prop (30) extends downwards to make it in L-shape. A connecting unit fitting hole (31) set on the extending part of the prop (30) can be locked with the prop fitting hole (134) on the connecting unit (13) correspondingly. The prop (30) can be rotated through the prop fitting hole (134) as a fulcrum. A connecting plate 1 fitting hole (32) is set on the prop (30), and many tenons (33) are set on the prop (30) equidistantly to make them locked with the tenon holes (61) on the drop leaf (60) correspondingly. Therefore, the drop leafs (60) can be set on the prop (30) stably through the tenons (33) and the tenon holes (61) locking each other.
Referring to FIG. 3, a blocker (41) is set on one edge of the connecting plate 1 (40) which set on the prop (30). The connecting plate 2 fitting hole (43) and the prop fitting hole (42) which can be correspondingly locked with the connecting plate 1 fitting hole (32) are set on the connecting plate 1 (40), therefore, it makes the connecting plate 1 (40) rotate through the connecting plate 1 fitting hole (32) as a fulcrum.
Referring to FIG. 3, the connecting plate 2 (50) is set on the leg (20) and is connected with the connecting plate 1 (40). A locking hole (53) is set on one end of the connecting plate 2 (50) and can be connected with another connecting plate 2 (50). A connecting plate 1 fitting hole (51) is set on another end of the connecting plate 2 (50) and can be locked correspondingly with the connecting plate 2 fitting hole (43). The connecting plate 2 (50) can be rotated through the connecting plate 2 fitting hole (43) as a fulcrum, but the range of its rotating is limited by the blocker (41) on the connecting plate 1 (40). A leg fitting hole (52) set on the connecting plate 2 (50) can be locked correspondingly with the connecting plate fitting hole (22) on the leg (20) and the connecting plate 2 (50) can be rotated through the connecting plate fitting hole (22) as a fulcrum. As shown in FIG. 1, the supporting leg (14) which set under the plate body (11) is connected with the connecting plate 2 (50) at leg fitting hole (52).
As shown in FIGS. 4 and 5, when the whole structure is in folding position, loose the drop leaf (60) from the prop (30) first. Pile the drop leaves (60) on the plate body (11) of the main frame (10) one by one in forward and then in reverse if the drop leaf (60) is multi-plate type (as shown in FIG. 2). If it is entire-plate type, as shown in FIG. 7, move the drop leaf (60) downwards, and rotate the prop (30) downwards to move the connecting plate 1 (40) close to the prop (30). Meanwhile, the connecting plate 2 (50) is driven by the connecting plate 1 (40) to move inwards, and the move of the connecting plate 2 (50) would narrow the open angle of the leg (20). When the prop (30) rotates downwards and is perpendicular with the plate body (11), the prop (30), the connecting plate 1 (40) and the leg would be parallel to each other. Rotate the connecting unit (13) inwards to move the prop (30), the connecting plate 1 (40), the connecting plate 2 (50), and the leg (20) close to the bottom of the plate body (11), and the supporting leg (14) is driven by the connecting plate 2 (50) being folded and then close to the bottom of the plate body (11). Therefore, the whole folding structure is completed.
Referring to FIGS. 4 and 5, when the whole structure is in unfolding position, rotate the connecting unit (13) downwards to open the supporting leg (14), and then rotate the prop (30) upwards to move the connecting plate 1 (40) downwards. Meanwhile, the connecting plate 2 (50) is driven by the connecting plate 1 (40) to move outwards, and the move of the connecting plate 2 (50) would expanse the open angle of the leg (20). The unfolding structure is completed when the prop (30) rotates upwards and is perpendicular with the plate body (11), the connecting plate 2 (50) leaning to the blocker (41) on the connecting plate 1 (40) is parallel to the connecting plate 1 (40), and then set the drop leaf (60) on the prop (30).
Another example of the present invention is shown in FIGS. 8 through 11, wherein the main frame (10) comprises a long-shaped plate body (11) and a board (62) which is connected on each side of the plate body (11) with flexible wire, and the whole appearance of the board (62) is still a rectangular solid with long sides and wide brims. A concave body (12) is set on each side at the bottom of the plate body (11). The entire-plate-type board (62) is locked on the prop (30). A connecting unit locking hole (121) is set on the bottom of the concave body (12), and a connecting unit (13) is set inside the hollow space of the concave body (12). Inside the connecting unit (13) there is a receiving concave (131), and a concave body locking hole (132) which set on each narrow side end of the connecting unit (13) can be locked with the connecting unit locking hole (121) of the concave body (12) correspondingly. The connecting unit (13) cannot be rotated. A leg fitting hole (133) and a prop fitting hole are set on the front side of the connecting unit (13).
Referring to FIG. 10, the leg (20) is set in the receiving concave (131) of the connecting unit (13), and a connecting unit fitting hole (21) on top end of the leg (20) can be locked with the leg fitting hole (133) on the connecting unit (13) correspondingly and rotate the leg (20) through the leg fitting hole (133) as a fulcrum. A connecting plate fitting hole (22) is set on the leg (20).
Referring to FIG. 10, the prop (30) is set on the connecting unit (13), and the length of the prop (30) is the same as the wide brim of the board (62). The front end of the prop (30) extends downwards to make it in L-shape. A connecting unit fitting hole (31) set on the extending part of the prop (30) can be locked with the prop fitting hole (134) on the connecting unit (13) correspondingly. The prop (30) can be rotated through the prop fitting hole (134) as a fulcrum. A connecting plate 1 fitting hole (32) is set on the prop (30). Referring to FIG. 10, a blocker (41) is set on one edge of the connecting plate 1 (40) which set on the prop (30). The connecting plate 2 fitting hole (43) and the prop fitting hole (42) which can be correspondingly locked with the connecting plate 1 fitting hole (32) are set on the connecting plate 1 (40), therefore, it makes the connecting plate 1 (40) rotate through the connecting plate 1 fitting hole (32) as a fulcrum.
Referring to FIG. 10, the connecting plate 2 (50) is set on the leg (20) and is connected with the connecting plate 1 (40). A locking hole (53) is set on one end of the connecting plate 2 (50) and can be connected with another connecting plate 2 (50). A connecting plate 2 fitting hole (51) is set on another end of the connecting plate 2 (50) and can be locked correspondingly with the connecting plate 2 fitting hole (43). The connecting plate 2 (50) can be rotated through the connecting plate 2 fitting hole (43) as a fulcrum, but the range of its rotating is limited by the blocker (41) on the connecting plate 1 (40). A leg fitting hole (52) set on the connecting plate 2 (50) can be locked correspondingly with the connecting plate fitting hole (22) on the leg (20) and the connecting plate 2 (50) can rotate through the connecting plate fitting hole (22) as a fulcrum.
Referring to FIG. 11, when the whole structure is in folding position, rotate the prop (30) downwards to move the connecting plate 1 (40) close to the prop (30). Meanwhile, the connecting plate 2 (50) is driven by the connecting plate 1 (40) to move inwards, and the move of the connecting plate 2 (50) would narrow the open angle of the leg (20). When the prop (30) rotates downwards and is perpendicular with the plate body (11), the prop (30), the connecting plate 1 (40) and the leg would be parallel to each other. Therefore, the whole folding structure is completed.
Referring to FIG. 11, when the whole structure is in unfolding position, rotate the prop (30) upwards to move the connecting plate 1 (40) downwards. Meanwhile, the connecting plate 2 (50) is driven by the connecting plate 1 (40) to move outwards, and the move of the connecting plate 2 (50) would expanse the open angle of the leg (20). The unfolding structure is completed when the prop (30) rotates upwards and is perpendicular with the plate body (11), the connecting plate 2 (50) leaning to the blocker (41) on the connecting plate 1 (40) is parallel to the connecting plate 1 (40), and then set the board (62) on the prop (30).
