Description

[Technical Field]

[0001] The present invention relates to a folding table that can be folded into a flat surface by rotating its legs. [Background technology]

[0002] Traditionally, folding tables have been widely used for multipurpose outdoor and indoor use. These tables were primarily lightweight and portable, and were often used for camping, barbecues, picnics, etc.

[0003] Furthermore, these tables had a structural feature in that the tabletop and legs were connected by rotatable hinges, allowing them to be folded up compactly when not in use.

[0004] Subsequent technological developments have led to improvements in materials and stronger hinge mechanisms for this type of folding table, resulting in more durable and easier-to-operate products appearing on the market. In particular, the use of durable materials such as wood and metal has led to their use not only in homes but also in commercial facilities and event venues.

[0005] As a product relating to such folding tables, there is a wooden folding table described in Non-Patent Document 1.

[0006] This product has a pair of intersecting legs, and after use, can be folded compactly by rotating each leg. This product is designed so that when each leg is folded, the rod-shaped stopper on the underside of the tabletop is rotated and its end is positioned between the cross members provided on each leg, thereby preventing the legs from rotating.

[0007] This prevents the legs from unfolding unexpectedly, improving portability and storage convenience, while providing a stable workspace when in use. [Prior art documents] [Patent documents]

[0008] [Non-Patent Document 1] https: / / www.cainz.com / g / 4549509671237.html Summary of the Invention [Problem to be solved by the invention]

[0009] However, in the product described in Non-Patent Document 1, the end of the stopper is positioned as described above to prevent the rotation of each leg, so there is a gap between the end of the stopper and the penetrating member of the leg, which allows the leg to rotate slightly. Furthermore, there is a risk that the legs may unfold due to an unexpected rotation of the stopper, and the folded state may not be maintained stably.

[0010] The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide a folding table that is more convenient to use while maintaining the folded state more stably. [Means for solving the problem]

[0011] In order to solve the above problem, the present invention provides a chair comprising a top plate portion and legs, The top plate portion has a substantially plate-shaped top plate body, a side wall portion hanging down from a periphery of the top plate body, and a stopper portion provided on a rear surface of the top plate body, The leg portion has an outer leg portion including a pair of outer rods whose upper portions are rotatably connected to the top plate portion, an inner leg portion including a pair of inner rods that abut against the outer rods, and a connecting portion that pivotally supports and connects the outer leg portion and the inner leg portion at their abutting portions, The outer leg portion and the inner leg portion are configured to be able to transition between an open leg state in which they support the top plate portion in a substantially X-shape in side view and a closed leg state in which they abut against the back surface of the top plate portion in a substantially I-shape in side view and are folded by rotating via the connecting portion, The stopper portion includes a stopper portion main body having an elongated body, and a support portion that supports the stopper portion main body rotatably about an axis perpendicular to the surface of the top plate main body, The stopper portion main body is configured to be positioned in a closed leg holding position in which its both ends press against the inner surfaces of each inner rod in the closed leg state by rotating via the support portion, thereby being able to clamp the outer leg portion and the inner leg portion together with the side wall portion.

[0012] According to the present invention, the closed state of the legs can be stably maintained with a simple structure by clamping the legs with the stopper body and the side wall without swinging the legs.

[0013] In a preferred embodiment of the present invention, both ends of the stopper body are rounded in plan view.

[0014] With this configuration, the stopper body can be smoothly moved between the closed leg holding position and the position that allows each leg to rotate with little force.

[0015] In a preferred embodiment of the present invention, the top plate portion has a limiting member that limits the rotation range of the stopper portion main body, The restricting member abuts against the stopper body when the stopper body is in the closed leg holding position.

[0016] This configuration can prevent the stopper portion body from rotating due to unnecessary external force being applied to it, causing both ends to move away from the closed leg holding position.

[0017] In a preferred embodiment of the present invention, the inner legs include suspension rods suspended from upper portions of the inner rods, The suspension rod abuts against the side wall portion in the open state, The stopper body is configured to be able to clamp the inner leg together with the side wall portion by rotating via the support portion so that, in the open leg state, one end of the stopper body is positioned in an open leg holding position where it presses against the inner surface of the suspension rod.

[0018] This configuration allows the legs to be stably maintained not only in the closed position but also in the open position, preventing the legs from rotating unnecessarily when transporting the folding table in the open position.

[0019] In a preferred embodiment of the present invention, in the closed leg holding position, the extending direction of the stopper portion main body in a plan view is approximately perpendicular to the extending direction of the outer leg portion and the inner leg portion in a plan view, and is approximately parallel to the extending direction of the suspension rod in a plan view, the stopper portion main body is configured to be able to be positioned at a rotation restriction position in the open leg state by rotation via the pivot support portion, where one end portion thereof is adjacent to and faces the inner circumferential surface of the suspension rod and abuts against the restriction member, The stopper portion main body rotates from the closed leg holding position, via the open leg holding position, to the rotation restricted position by an angle of 90 degrees or more.

[0020] With this configuration, one end of the stopper portion main body is positioned adjacent to the inner surface of the suspension rod without pressing against it, while its rotation is restricted by the restricting member when it is further rotated from the open leg holding position to a rotation restricted position. In this case, a greater external force is required to rotate one end of the stopper portion main body from the rotation restriction position toward the closed leg holding position compared to when the stopper portion rotates away from the open leg holding position toward the closed leg holding position. This more effectively prevents the stopper body from rotating due to unnecessary external force, which causes each leg to rotate unnecessarily when the legs are in the spread-leg position, thereby maintaining a more stable spread-leg position.

[0021] In a preferred embodiment of the present invention, the side wall portion and the suspension rod are provided with a fitting projection and a fitting hole that come into contact with each other and fit together in the open leg state.

[0022] With this configuration, the legs are more stably maintained in the open position. [Effects of the Invention]

[0023] According to the present invention, it is possible to provide a folding table that is more convenient while maintaining the folded state more stably. [Brief explanation of the drawings]

[0025] A folding table according to an embodiment of the present invention will be described below with reference to FIGS. The following embodiment is an example of the present invention, and the present invention is not limited to the following embodiment. In each figure, the symbol X indicates a folding table according to this embodiment. In each figure, portions that pivotally support members, such as pivotal support portions S2 described below, are indicated by gray circles in the perspective views or side views, and by gray dotted lines in the plan views.

[0026] <Configuration> The configuration of the folding table X will be described below with reference to FIGS. 1 is a perspective view of the folding table X as seen from the side of a top plate 1 (to be described later), and FIG. 2 is a perspective view of the folding table X as seen from the side of legs 2 (to be described later).

[0027] As shown in FIG. 1, the folding table X includes a top panel 1 and legs 2. The folding table X can be made entirely of wood, but may also be made of metal, plastic, or a combination of these.

[0028] The top plate portion 1 has a roughly rectangular top plate main body 11, a side wall portion 12 hanging down from the periphery of the top plate main body 11, a stopper portion S provided on the back surface of the top plate main body 11, and a limiting member L that limits the rotation range of the stopper portion main body S1 described later.

[0029] The top plate body 11 is formed as a single flat plate-like body as a whole by joining together a plurality of substantially rectangular plate-like bodies at their long sides. Furthermore, substantially rectangular end reinforcing plates r1 are joined to the rear surface of the top plate main body 11 at both ends in the long side direction and over the entire length in the short side direction. Furthermore, a substantially rectangular central reinforcing plate r2 is joined to the rear surface of the top plate body 11 at approximately the center in the long side direction, spanning the opposing inner peripheral surfaces of each long side wall portion 12a, which will be described later. The end reinforcing plates r1 and the center reinforcing plate r2 do not necessarily have to be provided.

[0030] The side wall portion 12 includes long side wall portions 12a hanging down from both long sides of the top plate body 11, and a short side wall portion 12b hanging down from one end side.

[0031] Each of the long side wall portions 12a and the short side wall portions 12b is substantially rectangular parallelepiped in shape. Further, each long side wall portion 12a extends over the entire length of each long side of the table top body 11, whereas each short side wall portion 12b is configured to have an overall length shorter than the short sides of the table top body 11. As a result, in the closed leg state, a placement space k is formed in which the distal ends of the outer leg portion 21 and the inner leg portion 22, which will be described later, are placed and accommodated on the reinforcing plate r.

[0032] The stopper portion S includes a long stopper portion body S1 and a pivotal support portion S2 (see FIG. 3, etc.) that pivotally supports the stopper portion body S1 about an axis perpendicular to the surface of the top plate body 11. In the following description, the end of the stopper portion main body S1 that presses the suspension rod 22c (described later) will be referred to as one end, and the other end will be referred to as the other end.

[0033] The stopper portion main body S1 has both ends that are rounded in plan view. More specifically, the stopper portion main body S1 has an arched shape configured such that the vertices of both ends are formed on the center line along the long side direction of the stopper portion main body S1 in a plan view. The overall length of the stopper portion body S1 is configured to be slightly longer than the overall length of the central reinforcing plate r2.

[0034] The pivot support portion S2 is a member such as a bolt that connects and pivotally supports the stopper portion main body S1 to the central reinforcing plate r2. The pivotal support position of the pivotal support portion S2 is closer to the other end side than the center.

[0035] The limiting member L is a small, approximately rectangular piece protruding from the back surface of the top plate main body 11, and is provided in pairs so that its side abuts the end surface of the central reinforcing plate r2 and is positioned diagonally across the support portion S2. The number of restricting members L may be one.

[0036] The leg portion 2 has an outer leg portion 21 including a pair of outer rods 21a whose upper portions are rotatably connected to the top plate portion 1, an inner leg portion 22 including a pair of inner rods 22a that abut against each of the outer rods 21a, and a connecting portion 23 that supports and connects the outer leg portion 21 and the inner leg portion 22 at their abutting portions.

[0037] The outer leg portion 21 includes the outer rods 21a and a pair of through members 21b suspended from the outer rods 21a.

[0038] The base end side of each outer rod 21a is rotatably supported on the inner peripheral surface of one end side of each long side wall portion 12a. Both ends of each outer rod 21a are rounded in side view.

[0039] Each of the penetrating members 21b is a thin plate-like body having a substantially rectangular shape, and is arranged so that the connecting portion 23 is provided between the penetrating members 21b in a plan view when the legs are in the open position. Furthermore, each of the through members 21b is suspended from the opposing side surfaces of each of the outer rods 21a.

[0040] The inner leg portion 22 includes the above-mentioned inner rods 22a, a pair of through members 22b suspended from each inner rod 22a, and a suspension rod 22c suspended from the upper part of each inner rod 22a.

[0041] Each inner rod 22a is disposed inside each outer rod 21a, and its tip end has a rounded shape in a side view.

[0042] Each of the penetrating members 22b is a thin plate-like body having a substantially rectangular shape, and is arranged so that the connecting portion 23 is provided between the penetrating members 22b in a plan view when the legs are in the open position. Furthermore, each of the through members 22b is suspended from the opposing side surfaces of each of the inner rods 22a.

[0043] The suspension rod 22c is configured in a substantially rectangular parallelepiped shape, and is connected to the upper portion (base end side) of each inner rod 22a so as to be rotatable about an axis in the direction in which it extends.

[0044] The connecting portions 23 are members such as a pair of bolts that pivotally support the outer rods 21a and the inner rods 22a that contact them at approximately the center in the longitudinal direction.

[0045] 1 and 2, the stopper portion main body S1 is disposed in an open leg holding position where one end thereof presses the inner peripheral surface of the suspension rod 22c as shown in FIG.

[0046] More specifically, in the open position, one side surface of the suspension rod 22c is in contact with the inner peripheral surface of the short-side side wall portion 12b over its entire length. Then, by rotating via the support portion S2, the extension direction of the stopper portion main body S1 becomes approximately parallel to the extension direction of each leg portion 21, 22 (the long side direction of the tabletop main body 11) and approximately perpendicular to the extension direction of the suspension rod 22c (the short side direction of the tabletop main body 11), so that the apex of one end of the stopper portion main body S1 presses against the suspension rod 22c.

[0047] As a result, the inner leg 22 (suspension rod 22c) is sandwiched between the stopper body S1 and the short side wall 12b. The position of the stopper portion main body S1 in this state is the leg-opening holding position. The stopper portion main body S1 does not come into contact with the restricting members L when placed in the leg-open holding position.

[0048] In addition, the short side wall portion 12b and the suspension rod 22c are provided with a fitting protrusion t1 and a fitting hole t2 (see FIGS. 6, 10, etc.) that come into contact with each other and fit together when the legs are in the open position.

[0049] The fitting projection t1 is a dowel projecting from approximately the center of the inner peripheral surface of the short side wall portion 12b. The fitting hole t2 is a through hole provided in approximately the center of the suspension rod 22c.

[0050] <How to use> Hereinafter, with reference to FIGS. 4 to 10, a method of using the folding table X will be described based on the open leg state shown in FIGS. 5 to 8, (a) shows a plan view seen from the rear surface side, and (b) shows a side view.

[0051] Hereinafter, the method of use in the spread-leg position will be described with reference to FIG. In Figure 4, the stopper part main body S1 positioned in the closed leg holding position described below is shown by a dotted line in the overall view, and the stopper part main body S1 positioned in the open leg holding position is shown by a dotted line in the enlarged view.

[0052] From the state shown in Figure 3, the user can further rotate the stopper portion main body S1 counterclockwise via the support portion S2, so that one end is adjacent to and facing the inner surface of the suspension rod 22c and abuts against each restricting member L, thereby achieving the state shown in Figure 4.

[0053] The position of the stopper portion main body S1 in this state is the rotation restriction position. That is, the restricting members L prevent the stopper portion main body S1 from rotating further counterclockwise from this state. Therefore, even if the suspension rod 22c presses the stopper portion main body S1 as the outer leg portion 21 rotates, the resulting counterclockwise rotation of the stopper portion main body S1 is prevented by the restricting member L, and the leg-open state is stably maintained.

[0054] Here, the rotation angle θ of the stopper portion main body S1 from the closed leg holding position, via the open leg holding position shown in FIG. 3, to the rotation restricted position is 90 degrees or more. In this embodiment, the rotation angle θ is approximately 95 degrees. It is preferable that the rotation angle θ is less than 105 degrees.

[0055] As a result, when the stopper portion main body S1 is positioned in the rotation restriction position, the pressing force at the apex of one end (indicated by the black dot) is released, and the end face shifted toward the closed leg holding position from the apex comes adjacent to and faces the inner surface of the suspension rod 22c. When rotating further clockwise from this state via the open leg holding position, a rotational force is required to counter the frictional force between the suspension rod 22c that occurs on the way to the open leg holding position and the reaction force from the suspension rod 22c.

[0056] Therefore, in this state, unless an external force is applied artificially, the stopper portion main body S1 only undergoes a slight rotational movement between the rotation restriction position and the leg-open holding position. Furthermore, as described above, the open leg state is stably maintained in any position. The rotation angle θ is not limited to the above, and may be any angle at which one end of the stopper portion main body S1 is adjacent to and faces the inner circumferential surface of the suspension rod 22c.

[0057] The flow of folding the folding table X will be described below with reference to FIGS.

[0058] First, from the leg-spread state shown in Figures 1 to 3, the user rotates the stopper portion main body S1 clockwise via the pivot support portion S2 to release the pressing force on the suspension rod 22c, thereby bringing the user into the state shown in Figure 5.

[0059] Next, the user rotates the outer leg portion 21 outward around the base end side of the outer leg portion 21 as an axis to remove the fitting protrusion t1 from the fitting hole t2, resulting in the state shown in FIG.

[0060] Next, the user rotates the inner leg portion 22 by the connecting portion 23 so that the legs 21, 22 are in a state in which they form a substantial I shape in a side view, as shown in FIG. In this state, the inner side of each outer rod 21a and the outer side of each inner rod 22a are in contact with each other over substantially the entire surface. In this state, the penetrating members 21b of the outer leg portion 21 and the penetrating members 22b of the inner leg portion 22 are arranged to face each other.

[0061] Next, the user rotates the legs 21, 22 around the base end of the outer leg 21 as an axis, thereby bringing them into contact with the rear surface of the tabletop 1, and thus into the state shown in FIG. 8 (closed leg state). In this state, the distal end of each of the legs 21, 22 is accommodated in the placement space k and is accommodated on the rear surface of the top plate 1 so as to protrude from one short side of the top plate 1. In this state, the extending direction of the legs 21 and 22 and the surface direction of the tabletop body 11 are substantially parallel to each other.

[0062] Finally, the user rotates the stopper portion main body S1 clockwise via the pivot support portion S2 to place it in the closed leg holding position where both ends press against the inner surfaces of each inner rod 22a, resulting in the state shown in Figure 9.

[0063] As a result, the legs 21 and 22 are sandwiched between the stopper body S1 and the long side wall 12a. The position of the stopper portion main body S1 in this state is the closed leg holding position. In this state, each of the restricting members L is in contact with the stopper portion main body S1.

[0064] Figure 10 is an oblique view of the folding table X in the state where each leg 21, 22 is in the closed leg state and the stopper body S1 is positioned in the closed leg holding position as shown in Figure 9, (a) is an oblique view seen from the top plate 1 side, and (b) is an oblique view seen from the leg 2 side.

[0065] When the user wishes to change from the closed leg position shown in FIG. 10 to the open leg position shown in FIGS. 1 and 2, the user simply follows the steps above in reverse. In this way, each leg 21, 22 is configured to be able to transition between an open leg state in which it supports the top plate 1 in an approximately X-shape when viewed from the side, and a closed leg state in which it abuts against the underside of the top plate 1 and is folded, in an approximately I-shape when viewed from the side, by rotating via the connecting portion 23.

[0066] In addition, in the state shown in Figure 10, the user may rotate the stopper portion main body S1 counterclockwise and position its tip side between the respective penetrating members 21b, 22b to maintain the closed leg state as in the prior art.

[0067] <Effects> According to this embodiment, the legs 21, 22 are sandwiched between the stopper body S1 and the long side wall 12a, and the closed state can be stably maintained with a simple configuration without swinging.

[0068] Furthermore, since both ends of the stopper portion main body S1 have a rounded shape when viewed in a plane, the movement of the stopper portion main body S1 between the closed leg holding position and the position that allows each leg 21, 22 to rotate can be performed smoothly with little force.

[0069] In addition, by each restricting member L abutting against the stopper portion main body S1 at the closed leg holding position, excessive clockwise rotation of the stopper portion main body S1 is restricted, and the situation in which both ends move away from the closed leg holding position can be prevented.

[0070] Furthermore, by positioning the stopper body S1 in the leg-open holding position, not only the closed leg state but also the open leg state can be stably maintained, and unnecessary rotation of each leg 21, 22 can be prevented when transporting the folding table X in the open leg state, for example.

[0071] Furthermore, by positioning the stopper body S1 in the rotation restriction position, it is possible to more effectively prevent the stopper body S1 from rotating due to unnecessary external forces, which would otherwise cause the legs 21, 22 to rotate unnecessarily when in the spread-leg state, thereby maintaining a more stable spread-leg state.

[0072] Furthermore, the fitting protrusion t1 and the fitting hole t2 allow the legs to be more stably maintained in the open position.

[0073] The shapes and dimensions of the components shown in the above-described embodiment are merely examples and can be modified in various ways based on design requirements, etc. In addition, the word "abbreviated" in the application documents is a concept that means that the shape that follows has been chamfered or rounded, and that the elements that make up the shape have been deformed or changed in length within a range that does not impede the purpose of the shape.
