Description

[Technical Field]

[0001] The present invention relates to a folding table. [Background technology]

[0002] Various folding tables have been proposed in the past, with tabletops that can be rotated between a substantially horizontal usage position and an upright storage position (see, for example, Patent Document 1). This type of folding table is used, for example, for meetings in offices or schools, and when in use, multiple tables are arranged together, but when stored, the tabletops of each table are flipped up and rotated to a storage position, allowing multiple tables to be stacked (fitted together) one behind the other, thereby reducing the storage space required for the tables.

[0003] In the table of Patent Document 1, an axis plate is fixed to the top of the leg body, and a locking claw is engaged with the axis plate to selectively hold the tabletop and tabletop holder in an in-use position or a stored position. In addition, to prevent problems such as fingers or objects getting caught between the axis plate / locking claw and the tabletop holder, multiple covers are provided to cover the locking claws, etc.

[0004] In the table of Patent Document 1, a first cover body that hides the locking claws and other features when the tabletop is in the storage position is fixed to the tabletop support. However, when the tabletop is in the upright position, the first cover body is located above the axis plate, so it cannot hide the locking claws and other features. Therefore, a second cover body is rotatably suspended from the first cover body so that the second cover body hides the locking claws and other features when the tabletop is in the upright position. Because this second cover body is rotatable and hangs down under its own weight, it hangs down rotatably from the first cover body when the tabletop is in the usage position, which detracts from the appearance of the table and makes it susceptible to damage when foreign objects come into contact with it.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2017-080228 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made to improve this current situation, and aims to provide a folding table that can cover the tabletop locking mechanism with a single cover body in both the use position and the storage position of the tabletop. [Means for solving the problem]

[0007] The present invention is a folding table in which a tabletop is supported by legs via a pivot shaft and is configured to be rotatable between a substantially horizontal use position and an upright storage position, and is equipped with an arm member with a substantially U-shaped cross section that is attached to the underside of the tabletop in a downward-facing open position, a tabletop locking mechanism that is provided inside the arm member and holds the tabletop in the use position and the storage position, and a cover body that covers the tabletop locking mechanism, and the cover body is attached to the top of the legs at a position different from the pivot shaft. established The cover is supported rotatably via a cover shaft and is provided rotatably in conjunction with the rotation of the top plate and the arm member. Crate , The top plate locking mechanism is covered on both sides of the arm member in the longitudinal direction relative to the rotation shaft. It is something.

[0008] According to the present invention, by providing the cover shaft, which serves as the rotation axis of the cover body, at a position different from the rotation axes of the tabletop and the arm member and moving the cover body relative to the tabletop and the arm member, it is possible to cover the tabletop locking mechanism with one cover body regardless of the position of the tabletop, thereby preventing fingers from getting pinched, etc. Also, since there is no need to provide multiple cover bodies, the design around the connection point between the tabletop and the leg body can be simplified and the appearance can be improved.

[0009] In the folding table of the present invention, the cover axis may be provided on one of the cover body and the leg body, and a guide groove into which the cover axis fits may be provided on the other, so that the cover axis can move relatively within the guide groove when the tabletop rotates.

[0010] According to this aspect, the position of the cover body relative to the arm member can be controlled so that no gap is formed between the arm member and the cover body during the flap operation in which the top plate rotates, thereby preventing the problem of fingers or the like being pinched.

[0011] Another aspect of the present invention is , a folding table having a tabletop supported by legs via a pivot shaft and configured to be rotatable between a substantially horizontal use position and an upright storage position, the folding table comprising: an arm member having a substantially U-shaped cross section attached to the underside of the tabletop in a downward-opening position; a tabletop locking mechanism provided inside the arm member for holding the tabletop in the use position and the storage position; and a cover body covering the tabletop locking mechanism, the cover body being rotatably supported via a cover shaft provided on an upper part of the leg body at a position different from the pivot shaft, and being rotatable in conjunction with the rotation of the tabletop and the arm member; the cover shaft being provided on one of the cover body and the leg body, and a guide groove into which the cover shaft is fitted being provided on the other, and the cover shaft being configured to move relatively within the guide groove when the tabletop rotates; A first cover shaft and a second cover shaft are provided as the cover shafts, and a first guide groove into which the first cover shaft is fitted and a second guide groove into which the second cover shaft is fitted are provided as the guide grooves. The first cover shaft and the first guide groove control the rotation of the cover body, while the second cover shaft moves relatively within the second guide groove to control the relative position of the cover body and the arm member. It is something .

[0012] According to this aspect, the rotation of the cover body and its position relative to the arm member during the flap operation of the tabletop can be controlled with a simple configuration consisting of two sets of cover shafts and guide grooves, thereby ensuring high durability and reducing increases in manufacturing costs.

[0013] In the folding table of the present invention, an example can be given in which the cover shaft is provided on the cover body, and the cover main body of the cover body and the cover shaft member having the cover shaft are formed as separate parts.

[0014] According to this aspect, by configuring the cover body and the cover shaft as separate parts, the cover body can be attached to the leg body by simply aligning the cover body with the arm member and the leg body and then attaching the cover shaft member to the cover body, which makes assembly easy. In addition, the structure of the cover body can be kept from becoming too complicated, which prevents a significant increase in manufacturing costs.

[0015] In the folding table of the present invention, the cover body may be configured to cover at least the lower edge of the side surface of the arm member from the outside.

[0016] According to this aspect, the cover body hides the lower end portion of the side surface of the arm member, preventing fingers and the like from getting caught between the cover body and the arm member. By bringing the rotatable cover body into contact with the lower end portion of the arm member, the position of the cover body is stabilized, and the cover body can be made more compact than when it is in contact with the underside of the tabletop, thereby reducing manufacturing costs. [Effects of the Invention]

[0017] In the folding table of the present invention, a single cover can cover the tabletop locking mechanism in both the use position and the storage position of the tabletop. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] [Schematic configuration of one embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In this specification, for convenience, the terms "front-rear" and "left-right" are used to specify directions. The left-right direction is the direction in which a pair of legs 3, 3 are arranged, and the front-rear direction is the direction perpendicular to the left-right direction in a horizontal plane. The side from which the tabletop 1 flips up is referred to as the near side or front, and the opposite side is referred to as the far side or rear.

[0020] FIG. 1 is a perspective view showing the overall configuration of the table, with (A) showing the use position and (B) the storage position. FIG. 2 is a side view of the same table, with (A) showing the use position and (B) the storage position. FIG. 3 is a front view showing an enlarged view of one of the legs and the area around the tabletop support part of the table, with (A) showing the use position and (B) the storage position. FIG. 4 is a plan view showing an enlarged view of the area around the tabletop support part of the table in the use position. FIGS. 5 to 8 are side views showing the tabletop locking mechanism and the cover body in partial cross section, with FIG. 5 showing the tabletop in the use position, FIG. 6 showing it in the middle of a flap operation, FIG. 7 showing it in a pause position, and FIG. 8 showing it in the storage position.

[0021] As shown in FIGS. 1 to 4, the table 100 of this embodiment includes left and right leg bodies 3 and a tabletop 1 disposed thereon. The tabletop 1 is supported by the left and right leg bodies 3 via hinge pins that form a rotation axis 2 that extends horizontally from side to side. The tabletop 1 is configured to be flippable and rotatable about the rotation axis 2 between a substantially horizontal usage position (see FIGS. 1(A) and 2(A)) and a storage position in which the tabletop 1 stands up approximately parallel to the leg supports 7 of the leg bodies 3 (see FIGS. 1(B) and 2(B)). That is, the table 100 supports the tabletop 1 on the leg bodies 3 via the rotation axis 2, and is configured to be rotatable between the substantially horizontal usage position and the upright storage position. The rotation axis 2 may be configured as a shaft member or a pipe member other than a hinge pin.

[0022] The left and right edges of the underside of the tabletop 1 are connected to the upper ends of the left and right legs 3 via tabletop support parts 5 which have tabletop locking mechanisms 4 inside them that maintain the position of the tabletop 1. The lock is released by pushing upward on lock release operation levers 15 exposed on the left and right outward sides of the tabletop support parts 5, allowing the tabletop 1 to be rotated between the use position and the storage position. A pair of front and rear beam members 17 extending in the left-right direction are fixed to areas near the front and rear edges of the underside of the tabletop 1.

[0023] The tabletop support portion 5 is equipped with an upper arm 12 (arm member) with a generally U-shaped cross section that is attached to the underside of the tabletop 1 in a downward-facing open position. The upper arm 12 is made of metal, is arranged along the front-to-rear direction, and houses a tabletop locking mechanism 4 inside. The tabletop locking mechanism 4 is a mechanism that holds the tabletop 1 in the use position and the storage position, and is composed of a locking claw member 18 and a leg connecting member 20, which will be described later, etc.

[0024] A cover body 40 that covers the tabletop locking mechanism 4 is supported on the upper part of the leg body 3 (in this embodiment, a leg connecting member 20 described later). The cover body 40 is rotatably supported via a cover shaft 41 provided on the upper part of the leg body 3 at a position different from the rotation shaft 2, and is provided so as to be rotatable in conjunction with the rotation of the tabletop 1 and upper arm 12.

[0025] In the table 100, the cover shaft 41, which serves as the rotation shaft of the cover body 40, and the rotation shaft 2 of the tabletop 1 and upper arm 12 are provided at different positions. Therefore, the cover body 40 moves relative to the tabletop 1 and upper arm 12 when the position of the tabletop 1 changes (when the flap operates). This allows the tabletop locking mechanism 4 to be covered with a single cover body 40 regardless of the position of the tabletop 1, preventing fingers from getting pinched, etc. Furthermore, since there is no need to provide multiple cover bodies, the design around the connection point between the tabletop 1 and the leg body 3 can be simplified to improve the appearance.

[0026] The leg body 3 has a generally inverted T-shape with a cylindrical leg support 7 extending upward from the longitudinal center of a leg base 6 extending in the front-to-rear direction. The leg base 6 and leg support 7 are made of metal. A leg connecting member 20 that supports an upper arm 12 via a rotating shaft 2 is fixed to the upper end of the leg support 7. The leg connecting member 20 is made of metal (for example, aluminum die-cast) and forms the upper part of the leg body 3. The left and right leg connecting members 20 are connected via a connecting pipe 11 made of a metal square pipe extending in the left-right direction.

[0027] Casters 8, 8 are provided at both the front and rear ends of the underside of the leg base 6. A caster operating section 8a for locking and unlocking the casters 8 is provided at the front end of the upper surface of the leg base 6. By unlocking the casters 8, the casters 8 can be rolled on the floor, allowing the table 100 to be moved.

[0028] As shown in Figure 2(B), in the storage position, the tables 100 can be stacked front to back with the top surfaces of the table tops 1 facing the same direction at the front and rear. Cushioning members 62 are provided on the left and right edges of the front of the connecting pipe 11 that connects the left and right leg connecting members 20. The cushioning members 62 are made of resin or rubber, and protrude further forward than the leg supports 7 in side view. The cushioning members 62 prevent the legs 3 from contacting and damaging the table tops 1 of other tables 100 when the tables 100 are stacked for storage.

[0029] Next, each part of the table 100 will be described with reference to Figures 9 to 13. In the following description of each part, the front-to-back and up-to-down directions when the tabletop 1 is in the usage position will be used as reference. Figure 9 is an exploded perspective view of the tabletop support part. Figure 10 is a perspective view for explaining the installation operation of the cover body 40. Figure 11 is an exploded perspective view of the cover body 40. Figure 12 is a diagram for explaining the cover body 40, with (A) and (B) being side views and plan views of the cover main body 42, and (C) and (D) being side views and front views of the cover shaft member 48. Figure 13 is a perspective view of the upper part of the leg body 3 as seen obliquely from above the front, with (A) showing a state as seen from the outside left and right, and (B) showing a state as seen from the inside left and right.

[0030] [Upper leg structure] As shown in Figures 1 to 3, 5 to 8, 13, etc., the leg body 3 has metal leg connecting members 20 attached to the upper parts of the leg supports 7. The left and right leg connecting members 20 have symmetrical shapes with the center line of the tabletop 1 in the front-to-rear direction as the axis of symmetry. Each leg connecting member 20 has a substantially cylindrical insertion portion 21 that fits into the upper end of the leg support 7, a plate-like tabletop holding portion 22 that extends upward from the upper part of the insertion portion 21, and a substantially square pillar-shaped connecting protrusion 23 that extends inward to the left and right from the lower part of the tabletop holding portion 22.

[0031] The insertion portion 21 is inserted into the upper part of the leg support 7 and fixed to the leg support 7 by bolts (not shown) that are screwed into the left and right inward-facing side surfaces of the leg support 7. A notch 7a is provided at the upper end of the leg support 7 into which the lower rear side of the tabletop holding portion 22 and the base end of the connecting protrusion 23 fit, restricting rotation of the insertion portion 21 around its axis. The tabletop holding portion 22 has a plate-like shape that protrudes rearward from above the insertion portion 21 beyond the leg support 7, and its left and right side surfaces are arranged along the front-to-rear direction. The left and right leg bodies 3, 3 are integrated by connecting the connecting protrusions 23 of the left and right leg connecting members 20 with connecting pipes 11 made of square metal pipes.

[0032] [Top board support configuration] The left and right tabletop support parts 5 are fixed to the underside of the tabletop 1 near the left and right ends, and are rotatably supported at both ends of the rotation shaft 2. As shown in Figure 1 etc., the left and right tabletop support parts 5 have a roughly symmetrical structure with the center line of the tabletop 1 in the front-to-rear direction as the axis of symmetry. An upper arm 12 that constitutes the main body of the tabletop support part 5 is attached to the underside of the tabletop 1 with mounting screws (not shown).

[0033] 1 to 3, 9 and 10, etc., the metal upper arm 12 is hollow and has a generally U-shaped cross section, and includes an arm top surface 13 that is a plate-like member that is long in the front-to-rear direction and is attached to the underside of the tabletop 1, and arm side surfaces 14, 14 that extend downward from both the left and right edges of the arm top surface 13. The arm side surfaces 14 have a generally rectangular shape when viewed from the side, with rounded corners at both the front and rear ends.

[0034] [Top plate locking mechanism configuration] As shown in Figures 3 to 10, etc., a tabletop locking mechanism 4 is disposed between both arm side surface portions 14, 14 of the upper arm 12. The tabletop locking mechanism 4 has a tabletop holding portion 22 of the leg connecting member 20 and a locking claw member 18 that engages with the tabletop holding portion 22, and is configured to be able to hold the tabletop 1 in an in-use position, a stored position, or a temporary suspension position depending on the position at which the locking claw member 18 engages with the tabletop holding portion 22. The tabletop holding portion 22 is disposed between both arm side surface portions 14, 14 of the upper arm 12. The tabletop locking mechanism 4 is provided with an elastic biasing member 25 that biases the locking claw member 18 toward the rotation shaft 2.

[0035] Circular bearing holes 26, 26 are formed in the arm side surfaces 14, 14 of the upper arm 12, through which the rotation shaft 2 consisting of a hinge pin is inserted. A rotation shaft holding hole 16 opening on both the left and right sides is drilled in the tabletop holding part 22. The rotation shaft 2 is inserted through one of the bearing holes 26, the rotation shaft holding hole 16 of the tabletop holding part 22, and the other bearing hole 26 from the outside on the left and right of the upper arm 12. The rotation shaft 2 is held in place by a stopper 24 such as a retaining ring attached to the tip of the pin protruding inward on the left and right from the upper arm 12 so that it cannot come off the upper arm 12. As a result, the tabletop 1 and upper arm 12 are supported by the legs 3 so as to be rotatable about the rotation shaft 2.

[0036] As shown in Figures 4 to 9, etc., the locking claw member 18 is fixed to a locking claw spindle 19 extending in the left-right direction within the upper arm 12. The locking claw spindle 19 is rotatably supported in support holes 27, 27 provided on the arm side surfaces 14, 14 of the upper arm 12, closer to the front than the bearing holes 26, 26. By rotating the locking claw spindle 19, the locking claw spindle 19 can be rotated around the locking claw spindle 19.

[0037] [Configuration of locking claw components] The metal plate-like locking claw member 18 is provided in a substantially L-shape, with a rotation base end portion extending in a direction substantially perpendicular to the underside of the tabletop 1 and a rotation tip end portion bent toward the rotation shaft 2. A cylindrical portion 18a, through which the locking claw spindle 19 is inserted, is provided in the rotation base end portion of the locking claw member 18 near the tabletop 1. By inserting a pin or screw or the like into fixing holes provided in the cylindrical portion 18a and the locking claw spindle 19, the locking claw member 18 is connected to the locking claw spindle 19 so as not to rotate relative to it. The tip end portion of the locking claw member 18 has a locking claw portion 18b protruding toward the top plate 1, a locking claw corner portion 18c consisting of the corner of the tip end portion farthest from the top plate 1, and a second locking claw portion 18d provided between the locking claw portion 18b and the locking claw corner portion 18c.

[0038] The elastic biasing member 25 is composed of a kick spring, and the lock claw support shaft 19 is inserted into the coil portion 25a of the kick spring. One elastic piece 25b abuts against the arm top surface portion 13 of the upper arm 12, and the other crank-shaped elastic piece 25c is configured to engage with the portion of the rotating tip side portion of the lock claw member 18 on the opposite side from the lock claw portion 18b.

[0039] The left and right outer ends of the locking claw support shaft 19 protrude outward to the left and right from the upper arm 12, and the unlocking operation lever 15 is fixed to these left and right outer ends so that it cannot rotate relative to the locking claw support shaft 19. The locking claw support shaft 19 is inserted through the upper arms 12 of the left and right tabletop support parts 5, and the left and right unlocking operation levers 15 and the locking claw members 18 fixed to the left and right ends of the locking claw support shaft 19 are configured to move in conjunction with each other.

[0040] [Operation of the top plate locking mechanism] As shown in Figure 5 and other figures, when the tabletop 1 is in the use position, the locking claw member 18 is located in front of the tabletop holding portion 22. The locking claw portion 18b of the locking claw member 18 engages with the locking claw engagement portion 22b provided on the tabletop holding front portion 22a of the tabletop holding portion 22, thereby restricting upward rotation (spring-up rotation) of the front edge of the tabletop 1. When the tabletop 1 is in the use position, the underside of the arm top surface portion 13 of the upper arm 12 of the tabletop support portion 5 comes into contact with the tabletop holding top surface portion 22e provided in a substantially horizontal position above the tabletop holding portion 22, thereby restricting downward rotation of the front edge of the tabletop 1. This keeps the tabletop 1 in a substantially horizontal use position.

[0041] As shown in Figure 8, when the tabletop 1 is in the storage position, the locking claw member 18 is located above the tabletop holding portion 22. The locking claw corner portion 18c of the locking claw member 18 engages with the locking claw corner portion engaging portion 22d provided on the tabletop holding top surface portion 22e of the tabletop holding portion 22, thereby restricting the front edge of the tabletop 1 from rotating toward the front. Furthermore, when the tabletop 1 is in the storage position, the underside of the arm top surface portion 13 of the upper arm 12 of the tabletop support portion 5 comes into contact with a stopper portion 22c provided in a substantially vertical position at the rear of the tabletop holding portion 22, thereby restricting the front edge of the tabletop 1 from rotating toward the rear. This keeps the tabletop 1 in the upright storage position.

[0042] The tabletop holding portion 22 also has a roller member 28 at the upper front corner between the locking claw engagement portion 22b and the locking claw corner engagement portion 22d. The roller member 28 is formed, for example, from a plastic resin, and is housed in a roller housing recess 22g provided at the upper front corner of the tabletop holding portion 22, and is rotatably supported by roller shafts 29 installed on both side surfaces of the roller housing recess 22g. The front portion of the roller member 28 protrudes slightly forward from the tabletop holding front surface 22a of the tabletop holding portion 22 in a side view. Note that the front portion of the roller member 28 may be located at the same position as the tabletop holding front surface 22a of the tabletop holding portion 22 in a side view, or the entire roller member 28 may be located behind the tabletop holding front surface 22a.

[0043] 7, a second locking claw engagement portion 22f into which the second locking claw portion 18d and the locking claw corner portion 18c fit is recessed in the top plate holding top surface portion 22e of the top plate holding portion 22, at a position between the locking claw corner portion engagement portion 22d and the roller member 28. A metal wear prevention pin 22i for preventing wear of the top plate holding portion 22 is horizontally installed above the second locking claw engagement portion 22f. Below the hole for holding the wear prevention pin 22i, a hole is drilled into which a holding member (not shown) for holding the wear prevention pin 22i is attached.

[0044] During the flap operation that displaces the tabletop 1 between the use position and the storage position, the second locking claw portion 18d and the locking claw corner portion 18c fit into the second locking claw engagement portion 22f, temporarily holding the tabletop 1 in an inclined position in a side view. The second locking claw portion 18d engages with the wear prevention pin 22i provided on the second locking claw engagement portion 22f, thereby restricting the front edge of the tabletop 1 from rotating backward. The locking claw corner portion 18c also engages with the second locking claw engagement portion 22f, thereby restricting the front edge of the tabletop 1 from rotating forward. In this way, by being able to hold the tabletop 1 in an inclined position during the flap operation, the tabletop 1 can be prevented from rotating forcefully, improving safety during the flap operation.

[0045] When rotating the tabletop 1 to the use position or the storage position, the unlocking operation lever 15 is released and then the tabletop 1 is rotated slightly to release the locked state. When the unlocking operation lever 15 is released, the locking claw member 18 is urged toward the tabletop holding portion 22 by the elastic force of the elastic urging member 25. Then, when the tip end of the rotation of the locking claw member 18 reaches the locking claw engagement portion 22b, the locking claw corner engagement portion 22d, or the second locking claw engagement portion 22f, the elastic force of the elastic urging member 25 automatically locks it.

[0046] During the flap operation, the tip end of the locking claw member 18 comes into contact with the roller member 28 as it passes over the upper corner of the tabletop holding portion 22. At this time, the rotation of the roller member 28 ensures smooth movement of the locking claw member 18 and also reduces wear on the locking claw member 18 and tabletop holding portion 22 and the generation of metal chips.

[0047] As shown in Figure 5 and other figures, the tabletop holder 22 has a chip collection groove 22h with a low front and high rear position that extends from below the locking claw engagement portion 22b to the insertion portion 21 and opens to the tabletop holder front surface 22a. The lower end of the chip collection groove 22h opens to the top of the front of the insertion portion 21 and is installed inside the leg support 7 with the leg connecting member 20 connected to the leg support 7. A gap S is formed between the front of the insertion portion 21 and the inner wall of the leg support 7, allowing metal chips resulting from contact between the locking claw member 18 and the tabletop holder 22 to be collected through the gap S into the leg support 7. This prevents the metal chips from spilling onto the floor on which the table 100 is placed, making it user-friendly.

[0048] [Cover body configuration] As shown in Figures 1 to 8, etc., the table 100 is provided with a cover body 40 that covers the tabletop locking mechanism 4 to improve safety. The cover body 40 is rotatably supported on the upper part of the leg body 3 (the tabletop holding part 22 of the leg connecting member 20) via a cover shaft 41, and is configured to rotate in conjunction with the rotation of the tabletop 1 and upper arm 12. The cover shaft 41 is disposed in a position offset from the rotation shaft 2 of the tabletop 1 and upper arm 12 in side view.

[0049] 11 and 12, the cover body 40 has a cover main body 42 that is tub-shaped and opens upward along the longitudinal direction of the upper arm 12, and a pair of left and right cover shaft members 48 attached to the cover main body 42. The cover body 40 has a symmetrical structure with a center line extending in the front-to-rear direction as the axis of symmetry. The cover main body 42 is an injection-molded resin product and has a plate-shaped cover bottom surface portion 44 that is long in the front-to-rear direction, and a pair of left and right cover side surface portions 45, 45 that extend upward from both left and right edges of the cover bottom surface portion 44.

[0050] The cover side surface portion 45 has a generally trapezoidal shape with a long upper edge portion 45a in a side view. The upper edge portion 45a covers the lower edge portion of the arm side surface portion 14 of the upper arm 12 from the left and right outer sides. The cover bottom surface portion 44 is provided along the lower edge portion and the front and rear oblique sides of the cover side surface portion 45.

[0051] The cover bottom portion 44 has a bottom notch 44a that opens at its rear end and extends halfway in the front-to-rear direction. The cover main body 42 can be disposed below the top plate locking mechanism 4 by inserting the cover main body 42 from the front side so that the top plate holding portion 22 of the leg connecting member 20 is positioned within the bottom notch 44a. The cover bottom portion 44 has a cover bottom protrusion 44b that extends rearward from the front end of the bottom notch 44a. The cover bottom protrusion 44b is configured to fit into recesses provided in the top plate holding front portion 22a and the top plate holding top surface portion 22e of the top plate holding portion 22, covering the top plate locking mechanism 4.

[0052] A tongue 46 is provided at the front end of the cover bottom portion 44, extending upward toward the inside of the upper arm 12. The tongue 46 is disposed in front of the locking claw member 18 inside the upper arm 12, and prevents foreign objects such as the user's fingers from coming into contact with the locking claw member 18. Cover front grooves 40a, into which the lower ends of the arm side surface portions 14 fit, are formed between the left and right edges of the base end of the tongue 46 and the upper edges 45a of the left and right cover side surface portions 45, preventing left-right displacement of the front portion of the cover main body 42 relative to the upper arm 12.

[0053] A pair of left and right cover rear protrusions 47 are erected at positions near the left and right edges of the rear end of the cover bottom surface portion 44, spaced apart from the cover side surface portions 45. Cover rear grooves 40b into which the lower ends of the arm side surface portions 14 fit are formed between the cover rear protrusions 47 and the upper edges 45a of the left and right cover side surfaces 45, preventing left-right displacement of the rear of the cover main body 42 relative to the upper arm 12.

[0054] Furthermore, the left and right edge portions of the front end portion of the cover bottom portion 44 are positioned adjacent to the lower end portions of the arm side portion 14 within the cover front groove 40a, while the left and right edge portions of the rear end portion of the cover bottom portion 44 abut against the lower end portions of the arm side portion 14 within the cover rear groove 40b. This ensures the orientation of the cover main body 42 so that the upper edge portions 45a of the cover side portions 45 are approximately parallel to the lower end portions of the arm side portion 14, and prevents the cover main body 42 from entering excessively inside the upper arm 12.

[0055] A shaft member holding hole 45b for attaching a cover shaft member 48 having a cover shaft 41 is formed in a rearward position in the center of the front-to-rear direction of each cover side portion 45. The cover shaft member 48 is made of plastic resin and has a pair of upper and lower cover shafts, a first cover shaft 41a and a second cover shaft 41b, which are erected in the same direction on both longitudinal edge portions of a rounded rectangular shaft member base 48a. In this embodiment, two sets of cover shafts 41, each consisting of a first cover shaft 41a and a second cover shaft 41b, are provided on the left and right sides.

[0056] A pair of front and rear locking claws 48b are erected in the center of both front and rear edges of the shaft member base 48a. A step 45c is provided on the inner peripheral wall of the shaft member holding hole 45b to restrict movement of the shaft member base 48a into the cover main body 42. The cover shaft 41 is inserted into the shaft member holding hole 45b from the outside, left and right, to fit the cover shaft member 48, so that the peripheral edge of the shaft member base 48a faces the step 45c and the locking claws 48b engage with the inner wall surface of the cover side surface portion 45 around the shaft member holding hole 45b. This holds the cover shaft member 48 in place on the cover side surface portion 45 so that it cannot fall off.

[0057] As shown in FIGS. 5 to 8 and 13, guide grooves 49 into which the cover shafts 41 fit are recessed on each of the left and right side surfaces of the top plate holding portion 22. The left and right guide grooves 49 have the same shape and include a first guide groove 49a into which the first cover shaft 41a fits and a second guide groove 49b into which the second cover shaft 41b fits. In this embodiment, the first cover shaft 41a and the first guide groove 49a control the rotation of the cover body 40. Furthermore, the second cover shaft 41b moves relatively within the second guide groove 49b, thereby controlling the relative position of the cover body 40 and the upper arm 12.

[0058] The first guide groove 49a is formed in a straight line extending diagonally downward at a position diagonally below and in front of the rotation shaft holding hole 16. The lower end of the first guide groove 49a is provided at a position where the distance from the lower edge of the arm side surface portion 14 (the distance in a direction perpendicular to the direction in which the lower edge of the arm side surface portion 14 extends) is the same when the table top 1 is in the use position (see FIG. 5) and when it is in the storage position (see FIG. 8).

[0059] The second guide groove 49b is provided at a position diagonally below and in front of the rotation shaft holding hole 16, and is farther away from the rotation shaft holding hole 16 than the first guide groove 49a. The second guide groove 49b is formed in a shape that is curved convexly toward the rotation shaft holding hole 16.

[0060] [Cover body operation] As shown in Figure 5, when the tabletop 1 is in the use position, the first cover shaft 41a is located at the lower end of the first guide groove 49a, while the second cover shaft 41b is located at the rear end of the second guide groove 49b. The cover body 40 is supported by the cover shafts 41 (at least one of the cover shafts 41a and 41b) in a substantially horizontal position. The upper edge 45a of the cover side surface portion 45 covers the lower edge of the arm side surface portion 14 from the outside. The front end of the bottom cutout portion 44a of the cover bottom surface portion 44 is close to the lower part of the tabletop holding front surface portion 22a, and the cover bottom surface portion 44 covers the tabletop locking mechanism 4 from below. The cover side surface portion 45 covers the gap between the tabletop holding portion 22 and the lower edge of the arm side surface portion 14 from the side.

[0061] When the tabletop 1 is in the use position, downward rotation of the front part of the cover body 40 is restricted by the cover shaft 41 and the guide groove 49. Furthermore, the front end of the cover bottom part 44 comes close to the lower end of the arm side part 14 in the cover front groove 40a, thereby restricting upward rotation of the front part of the cover body 40. Furthermore, the rear end of the cover bottom part 44 comes close to the lower end of the arm side part 14 in the cover rear groove 40b at the rear of the cover body 40, thereby restricting upward rotation of the rear part of the cover body 40.

[0062] As shown in FIG. 8, when the tabletop 1 is in the storage position, the first cover shaft 41a is located at the lower end of the first guide groove 49a, just as it is in the use position. Meanwhile, the second cover shaft 41b is located at the front end of the second guide groove 49b. The cover body 40 is supported by the cover shaft 41 in the upright position. In this state, the upper edge 45a of the cover side surface portion 45 covers the lower edge of the arm side surface portion 14 from the outside. In addition, the front end of the bottom cutout portion 44a of the cover bottom surface portion 44 is close to the front portion of the tabletop holding top surface portion 22e, and the cover bottom surface portion 44 covers the tabletop locking mechanism 4 from the front. Note that the distance between the first cover shaft 41a and the lower edge of the arm side surface portion 14 when the tabletop 1 is in the storage position is the same as when the tabletop 1 is in the use position.

[0063] When the tabletop 1 is in the storage position, the forward rotation of the front part of the cover body 40 is restricted by the cover shaft 41 and the guide groove 49. Furthermore, the cover bottom surface portion 44 comes close to the lower end of the arm side surface portion 14 in the cover front groove 40a and the cover rear groove 40b, thereby restricting the backward rotation of the front part of the cover body 40 and restricting the backward rotation of the rear part of the cover body 40.

[0064] 6 and 7, when the tabletop 1 is inclined during the flap operation, the center of gravity of the cover body 40 is located forward of the cover shaft 41, and therefore a force acts on the cover body 40 to rotate the rear portion of the cover body 40 upward around the first cover shaft 41a. Meanwhile, the rear end portion of the cover bottom portion 44 comes into contact with the lower edge of the arm side portion 14 within the cover rear groove 40b, restricting the upward rotation of the rear portion of the cover body 40, and therefore the cover body 40 rotates in conjunction with the rotation of the tabletop 1 and upper arm 12.

[0065] For example, if the first cover shaft 41a is fixed to the tabletop holder 22 (leg 3), the distance between the first cover shaft 41a and the lower edge of the arm side surface portion 14 increases when the tabletop 1 is in the tilted position. This can be seen from the fact that the distance between the lower end of the first guide groove 49a and the lower edge of the arm side surface portion 14 in Figures 6 and 7 (when the tabletop 1 is in the tilted position) is larger than that in Figures 5 and 8 (when the tabletop 1 is in the use position or storage position). If the first cover shaft 41a is fixed to the tabletop holder 22, a gap is formed between the lower edge of the arm side surface portion 14 and the upper edge 45a of the cover side surface portion 45 during the flap operation of the tabletop 1.

[0066] It is possible to prevent this gap from being formed by increasing the height of the cover side surface portion 45. Specifically, the gap can be prevented from being formed by increasing the overlap between the cover side surface portion 45 and the arm side surface portion 14 when the table top 1 is in the use position and the storage position.

[0067] In this embodiment, the first cover shaft 41a is movable within the first guide groove 49a so as to move toward and away from the lower end of the arm side surface portion 14. This prevents a gap from being formed between the lower edge of the arm side surface portion 14 and the upper edge 45a of the cover side surface portion 45 during the flap operation of the tabletop 1. Specifically, when the cover body 40 rotates, the second cover shaft 41b moves within the second guide groove 49b, moving the first cover shaft 41a toward the upper arm 12. The second guide groove 49b is shaped so that the distance between the first cover shaft 41a and the lower edge of the arm side surface portion 14 remains substantially constant regardless of the angle of the tabletop 1, including the use position and the storage position. This allows the cover side surface portion 45 to cover the gap between the tabletop holding portion 22 of the tabletop locking mechanism 4 and the lower edge of the arm side surface portion 14, preventing fingers or other objects from getting caught in the gap, regardless of the angle of the tabletop 1.

[0068] 5 to 8, the cover body 40 slides along the upper arm 12 during the flap operation of the tabletop 1. The distance L between the rotation shaft 2 and the rear edge of the cover body 40 is shortest when the tabletop 1 is in the storage position, increases as the raised position of the tabletop 1 increases, and is longest when the tabletop 1 is in the storage position. In this embodiment, when the tabletop 1 is in the use position, the cover bottom portion 44, which is forward of the locking claw support shaft 19 and covers the tabletop locking mechanism 4 from below, slides toward the rear end of the upper arm 12 and is positioned so as to cover the locking claw member 18 of the tabletop locking mechanism 4 from the front when the tabletop 1 is in the storage position.

[0069] In this way, by providing the cover shaft 41, which serves as the rotation shaft of the cover body 40, at a position different from the rotation shaft 2 of the tabletop 1 and upper arm 12 and moving the cover body 40 relative to the tabletop 1 and upper arm 12, it is possible to cover the tabletop locking mechanism 4 with one cover body 40 regardless of the position of the tabletop 1, thereby preventing fingers from getting pinched, etc. Also, since there is no need to provide multiple cover bodies, the design around the connection point between the tabletop 1 and the leg body 3 can be simplified to improve appearance.

[0070] In this embodiment, a cover shaft 41 is provided on the cover body 40, and a guide groove 49 into which the cover shaft 41 fits is provided on the tabletop holding portion 22 of the leg body 3, so that the cover shaft 41 can move relatively within the guide groove 49 when the tabletop 1 rotates. This makes it possible to control the position of the cover body 40 relative to the upper arm 12 so that no gap is formed between the upper arm 12 and the cover body 40 during the flap operation in which the tabletop 1 rotates, preventing the inconvenience of fingers or the like being pinched.

[0071] In the present invention, the cover shaft 41 may be provided on the leg 3, and the guide groove 49 may be provided on the cover body 40.

[0072] In this embodiment, the cover shafts 41 include a first cover shaft 41a and a second cover shaft 41b, and the guide grooves 49 include a first guide groove 49a into which the first cover shaft 41a fits and a second guide groove 49b into which the second cover shaft 41b fits. The first cover shaft 41a and the first guide groove 49a control the rotation of the cover body 40, while the second cover shaft 41b moves relatively within the second guide groove 49b to control the relative position of the cover body 40 and the upper arm 12. This makes it possible to control the rotation of the cover body 40 and its position relative to the upper arm 12 during the flap operation of the tabletop 1 with a simple configuration of two sets of cover shafts 41a, 41b and guide grooves 49a, 49b, thereby ensuring high durability and reducing increases in manufacturing costs.

[0073] In this embodiment, the cover shaft 41 is provided on the cover body 40, and the cover main body 42 of the cover body 40 and the cover shaft member 48 having the cover shaft 41 are configured as separate parts. By configuring the cover main body 42 and the cover shaft 41 as separate parts in this way, the cover body 40 can be attached to the leg by the simple task of aligning the cover main body 42 with the upper arm 12 and the leg 3 and then attaching the cover shaft member 48 to the cover main body 42, which improves assembly efficiency. Furthermore, the configuration of the cover main body 42 can be prevented from becoming too complicated, preventing a significant increase in manufacturing costs.

[0074] In the present invention, the cover body may be one in which the cover main body and the cover shaft are integrally formed. For example, the cover main body may be split into left and right halves, and the cover shaft may be integrally formed with the half cover main body.

[0075] Furthermore, in this embodiment, the cover body 40 covers at least the lower edge portion of the arm side surface portion 14 of the upper arm 12 from the outside. This allows the cover body 40 to hide the lower end portion of the arm side surface portion 14, preventing fingers and the like from getting caught between the cover body 40 and the upper arm 12. Furthermore, by bringing the rotatable cover body 40 into contact with the lower end portion of the arm side surface portion 14, the posture of the cover body 40 is stabilized, and the cover body 40 can be made more compact than when the cover body 40 is in contact with the arm top surface portion 13 (or the underside of the top plate 1), thereby reducing manufacturing costs.

[0076] [Configuration of other embodiments] Next, another embodiment will be described with reference to Figures 14 to 17. Figure 14 is an enlarged plan view showing the periphery of a table top support part of a table in a use position in another embodiment. Figures 15 to 17 are side views showing, in partial cross section, the table top locking mechanism and cover body of the same embodiment, with Figure 15 showing the table top in a use position, Figure 16 showing the table top midway through flap operation, and Figure 17 showing the table top in a stored position. In Figures 14 to 17, parts that are the same as those in the embodiment described above with reference to Figures 1 to 13 are designated by the same reference numerals.

[0077] In this embodiment, a cover body 50 that covers the tabletop locking mechanism 4 is disposed within the upper arm 12. The cover body 50 is rotatably supported by the tabletop holding portion 22 at the top of the leg 3 via a cover shaft 51. The cover body 50 rotates in conjunction with the rotation of the tabletop 1 and the upper arm 12. The cover shaft 51 is disposed in a position offset from the rotation shaft 2 of the tabletop 1 and the upper arm 12 in side view. The cover shaft 51 protrudes from each of the left and right side portions of the tabletop holding portion 22.

[0078] The cover body 50 is, for example, an injection-molded resin product, and has a bilaterally symmetrical structure with a center line extending in the front-to-rear direction as the axis of symmetry. The cover body 50 has a pair of left and right cover side portions 55, 55 arranged between the arm side portion 14 and the tabletop holding portion 22 in a plan view. The cover side portion 55 is longer in the front-to-rear direction than the tabletop holding portion 22. The front portion of the cover side portion 55 is wider in the height direction and arranged further forward than the tabletop holding portion 22. The rear portion of the cover side portion 55 is arranged further rearward than the tabletop holding portion 22. The upper edge portion 55a of the cover side portion 55 is arranged within the upper arm 12 when the tabletop 1 is in the use position and the storage position.

[0079] The front lower end portions of the left and right cover side portions 55 are connected via a plate-shaped cover bottom portion 54. The front end portions of the left and right cover side portions 55 are connected via a plate-shaped cover front portion 56. The cover bottom portion 54 and the cover front portion 56 are provided continuously and close the front portion of the cover body 50. The rear edge portion 54a of the cover bottom portion 54 is disposed adjacent to the top plate holding portion 22. The front portion of the cover body 50 is configured to cover the top plate locking mechanism 4 from the front and below.

[0080] A pair of left and right cover upright portions 57 extend toward the inside of the upper arm 12 from positions near the rear ends of the left and right cover side portions 55. The upper ends of the left and right cover upright portions 57 are connected via a plate-shaped cover rear connecting portion 58.

[0081] Cover shaft engagement holes 59 drilled in the longitudinal midpoint of each of the left and right cover side surfaces 55 are fitted onto cover shafts 51 protruding from the side surfaces of the tabletop holder 22. In other words, the cover body 50 is rotatably supported by the tabletop holder 22 on the upper part of the leg 3 via the cover shafts 51. The center of gravity of the cover body 50 is located forward of the cover shaft engagement holes 59. The posture of the cover body 50 is maintained by the cover rear connecting portion 58 abutting against the arm top surface portion 13.

[0082] As shown in Figure 15, when the tabletop 1 is in the use position, the cover body 50 is supported by the cover shaft 51 in a substantially horizontal position. The cover side portion 55 covers the tabletop locking mechanism 4 from the side and also covers the gap between the tabletop holding portion 22 and the lower edge of the arm side portion 14. The rear edge portion 54a of the cover bottom portion 54 is close to the lower part of the tabletop holding front portion 22a. The cover bottom portion 54 and the cover front portion 56 cover the tabletop locking mechanism 4 from below and from the front.

[0083] 17, when the tabletop 1 is in the storage position, the cover body 50 is supported by the cover shaft 51 in an upright position. Even in this state, the cover side surface portion 55 covers the tabletop locking mechanism 4 from the side and also covers the gap between the tabletop holding portion 22 and the lower edge of the arm side surface portion 14. In addition, the rear edge portion 54a of the cover bottom surface is close to the front portion of the tabletop holding top surface portion 22e, and the cover bottom surface portion 54 covers the tabletop locking mechanism 4 from the front.

[0084] 16, when the tabletop 1 is inclined during the flap operation, the cover rear connecting part 58 rotates around the cover shaft 41 while contacting the arm top surface part 13 in conjunction with the rotation of the tabletop 1 and the upper arm 12. Even when the tabletop 1 is in the flap operation, the front part of the cover body 50 covers the tabletop locking mechanism 4.

[0085] 16, in this embodiment, when the table top 1 is in a flapping motion, a gap is formed between the upper edge 55a of the cover side surface portion 55 and the lower edge of the arm side surface portion 14. However, this gap can be closed by making appropriate design changes, such as increasing the height of the arm side surface portion 14, changing the degree to which the upper edge 55a of the cover side surface portion 55 fits into the upper arm 12 (making it fit deeper), or arranging the cover shaft 51 closer to the lower edge of the arm side surface portion 14.

[0086] 15 to 17, the cover body 50 slides relative to the upper arm 12 during the flap operation of the tabletop 1. The distance L between the pivot shaft 2 and the rear edge of the cover body 50 is shortest when the tabletop 1 is in the storage position, increases as the tabletop 1 is raised up, and is longest when the tabletop 1 is in the storage position. The cover bottom portion 54 of the cover body 50 covers the tabletop locking mechanism 4 from below, forward of the locking claw support shaft 19, when the tabletop 1 is in the use position. On the other hand, when the tabletop 1 is in the storage position, the cover bottom portion 54 of the cover body 50 slides toward the rear end of the upper arm 12 and is positioned so as to cover the locking claw member 18 of the tabletop locking mechanism 4 from the front.

[0087] In this way, by providing the cover shaft 51, which serves as the rotation shaft of the cover body 50, at a position different from the rotation shaft 2 of the tabletop 1 and upper arm 12 and moving the cover body 50 relative to the tabletop 1 and upper arm 12, it is possible to cover the tabletop locking mechanism 4 with one cover body 40 and prevent fingers from getting pinched, etc. Also, since there is no need to provide multiple cover bodies, the design around the connection point between the tabletop 1 and the leg body 3 can be simplified to improve the appearance.

[0088] In this embodiment, similar to the above embodiment described with reference to Figures 1 to 13, it is also possible to support the cover body 50 with two cover shafts 41 (first and second cover shafts 41a, 41b) and guide grooves 49 (first and second guide grooves 49a, 49b), so that no gap is formed between the upper edge 55a of the cover side portion 55 and the lower edge of the arm side portion 14.

[0089] [Other configurations] Although the embodiments have been described above, the present invention is not limited to the above-described embodiments and can be embodied in various forms. The configuration of each part is not limited to the illustrated embodiments, and various modifications are possible within the scope of the spirit of the present invention. For example, the configurations described in the above-described embodiments and modified examples (notes, etc.) may be combined, and additions, omissions, substitutions, and other modifications of the configurations are possible.

[0090] For example, instead of the second cover shaft 41b and the second guide groove 49b, a slide mechanism may be provided that slidably engages and holds the cover body 40 on the upper arm 12, so that when the tabletop 1 rotates, the first cover shaft 41a moves relatively within the first guide groove 49a and the cover body 40 slides along the upper arm 12. The slide mechanism can be formed, for example, by providing a groove or ridge extending in the front-to-rear direction on the arm side surface portion 14, and providing a ridge or claw on the cover body 40 that engages with the groove or ridge.

[0091] With this configuration, the position of the cover body 40 relative to the upper arm 12 can be controlled so that no gap is formed between the upper arm 12 and the cover body 40 during the flap operation in which the tabletop 1 rotates, preventing the problem of fingers or the like being pinched. Note that in this configuration, a cover shaft may be provided on the tabletop holding portion 22 (leg body 3), and a guide groove may be provided on the cover body 40. [Explanation of symbols]
