Description

[Technical field]

[0001] The present invention relates to a folding table whose top plate can be rotated to switch between a horizontal position and an upright position. [Background technology]

[0002] Conventionally, folding tables have been widely used in which a top plate is rotatably connected to the upper end of a leg body and the top plate can be fixed in a substantially horizontal use position and an upright position. The horizontal position and the upright position of the top plate are maintained by an engagement between a latch portion provided on the top plate side and a plate-shaped latch receiving portion provided on the leg body side, or by abutment between a member on the top plate side and the latch receiving portion (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-011724 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the position of the tabletop is maintained by the contact between the tabletop side member and a plate-shaped latch receiving portion, it may be difficult to increase the area of ​​the contacting portion due to restrictions on the plate thickness of the latch receiving portion, etc. Therefore, it is not necessarily easy to reliably maintain the position of the tabletop.

[0005] The present invention has been made in consideration of the above points, and has an object to make it easier to more reliably maintain the posture of the tabletop. [Means for solving the problem]

[0006] In order to achieve the above objectives, The present invention relates to A folding table including a top plate and legs supporting the top plate, the top plate being capable of being rotated to change the position of the top plate between a horizontal position and an upright position, moreover, A support member attached to the leg; a tabletop receiving member rotatably supported by the support member and fixed to the underside of the tabletop; Equipped with The support member is configured by joining a latch receiving member having a horizontal posture latch receiving portion and an upright posture latch receiving portion, and an abutment surface member having an abutment surface with the top board receiving member, The upright position of the tabletop is maintained by an engagement between a latch portion attached to the tabletop receiving member and the upright position latch receiving portion of the latch receiving member, The horizontal position of the top plate is maintained by engagement between the latch portion and the horizontal position latch receiving portion of the latch receiving member, and by abutment between the abutment surface of the abutment surface member and the top plate receiving member.

[0007] This allows the latch receiving member to maintain the horizontal and upright positions by engaging with the latch portion, and the abutment surface member to receive the load caused by abutting against the top plate receiving member in the horizontal position, making it easier to maintain the position of the top plate more reliably. Effect of the Invention

[0008] According to the present invention, the position of the tabletop can be easily maintained more reliably. [Brief description of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0011] As shown in Fig. 1, the folding table 1 includes a top plate 100 and a pair of legs 200, 200 that support the top plate 100. A rotation mechanism 300 is provided between the legs 200 and the top plate 100, and the top plate 100 can be rotated to switch between a horizontal position in which the top plate 100 is substantially horizontal as shown in Fig. 2 and an upright position in which the top plate 100 is substantially vertical as shown in Fig. 3. That is, in the horizontal position or the upright position, the top plate 100 is rotated by the rotation mechanism 300 around a top plate rotation shaft 330, which will be described later, and locked (maintained) in each position.

[0012] More specifically, the rotation mechanism 300 comprises a support member 310 attached to the leg 200, and a top plate receiving member 320 rotatably supported by the support member 310 via a top plate rotation axis 330, fixed to the underside of the top plate 100, and provided with a rotatable latch portion 341.

[0013] The support member 310 is configured by joining a latch receiving member 311 made of a steel plate and a contact surface member 312 made of aluminum die casting, as shown in Figs. 4 and 5. For convenience, the top plate receiving member 320, the fixed cover 410, and the movable cover 420 are omitted in Figs. 4 and 5. The latch receiving member 311 is formed with a horizontal position latch receiving portion 311a near the side edge with which the latch portion 341 engages when the top plate 100 is in a horizontal position, and with a standing position latch receiving portion 311b near the upper edge with which the latch portion 341 engages when the top plate 100 is in an upright position. The contact surface member 312 is formed with a contact surface 312a with which the top plate receiving member 320 abuts and receives a load from the top plate 100 when the top plate 100 is in a horizontal position. The latch receiving member 311 and the abutment surface member 312 are positioned relative to each other, for example, by fitting a boss portion 312b formed on the abutment surface member 312 into a fitting hole formed in the latch receiving member 311, and are joined together by screwing bolts 314, 315 inserted from the abutment surface member 312 side into female threads formed on the latch receiving member 311 and fixing them.

[0014] The support member 310 is attached by fixing the abutment surface member 312 to the leg body 200 with a bolt 313. The pair of legs 200 are connected via a connecting member 210 joined to the abutment surface member 312, thereby increasing the rigidity of the folding table. The support member 310 is provided so as to leave a predetermined gap between at least a portion of the support member 310 and the leg body 200 as shown in Fig. 6, and a movable cover side plate 421 of a movable cover 420 is disposed therebetween as described below.

[0015] The tabletop receiving member 320 rotatably supported by the support member 310 is formed to have a substantially U-shaped cross section by a fixed plate 321 fixed to the tabletop 100 and a pair of side plates 322 hanging down from both sides of the fixed plate 321, as shown in Fig. 6. The pair of side plates 322 are arranged to sandwich the latch receiving member 311 and the abutment surface member 312 of the support member 310, and are provided rotatably relative to the support member 310 via a tabletop rotating shaft 330 attached to the latch receiving member 311, for example. Here, the tabletop rotating shaft 330 may be attached to the abutment surface member 312, but by forming a bearing hole for the tabletop rotating shaft 330 in the latch receiving member 311, the tabletop rotating shaft 330 can be fixed without being affected by the punching taper of the hole formed in the abutment surface member 312, even when the abutment surface member 312 made of die casting is used as described above.

[0016] A latch shaft 342 is rotatably provided on the side plate 322 of the tabletop receiving member 320. A latch portion 341 is attached to the latch shaft 342, and in addition to the tabletop receiving member 320 abutting against the abutment surface 312a of the abutment surface member 312 as described above, the horizontal posture locking portion 341a engages with the horizontal posture latch receiving portion 311a of the latch receiving member 311, thereby maintaining the horizontal posture of the tabletop 100. In addition, the upright posture locking portion 341b at the corner near the tip of the latch portion 341 engages with the upright posture latch receiving portion 311b of the latch receiving member 311, thereby maintaining the upright posture of the tabletop 100.

[0017] A switching lever 343 is also attached to the latch shaft 342, and a torsion coil spring 344 is provided to bias the latch portion 341 so that the latch portion 341 rotates in a direction in which the horizontal position locking portion 341a and the upright position locking portion 341b of the latch portion 341 are locked to the horizontal position latch receiving portion 311a or the upright position latch receiving portion 311b of the latch receiving member 311. A switching lever connecting pipe 345 is also connected to the latch shaft 342, so that the latch shaft 342 provided on the other leg 200 side rotates in conjunction with the horizontal position locking portion 341a and the upright position locking portion 341b of the latch receiving member 311.

[0018] The open portion of the side plate 322 of the top plate receiving member 320 on the opposite edge to the fixed plate 321 is covered by a fixed cover 410, for example made of resin, and a movable cover 420, as shown in Figures 7 to 9, to prevent fingers from getting caught between the latch portion 341 and the latch receiving member 311.

[0019] More specifically, the fixed cover 410 is formed to have a substantially U-shaped cross section by fixed cover side plates 411·411 attached to the inside of the side plate 322 of the tabletop receiving member 320 so as to abut against the inside of the side plate 322, and a fixed cover part 412 connecting the fixed cover side plates 411·411 to cover the open part of the tabletop receiving member 320. The fixed cover part 412 is formed with an extension part 412a that protrudes outward from the outer surface of the fixed cover side plate 411, and a guide groove 413 is formed by providing a gap between the fixed cover part 412 and the edge of the side plate 322 of the tabletop receiving member 320. This makes it easy to avoid processing work such as forming the guide groove 413 by punching. Both ends of the guide groove 413 may be closed, but at least one of them, for example the end close to the leg 200, is open, which makes it easy to assemble the movable cover 420 described later.

[0020] The movable cover 420 is formed to have a substantially U-shaped cross section by movable cover side plates 421·421 arranged on the outside of the side plate 322 of the top plate receiving member 320 and a movable cover part 422 connecting the movable cover side plates 421·421, and is adapted to overlap with the fixed cover part 412 of the fixed cover 410 or to cover the open part of the top plate receiving member 320. That is, as shown in FIG. 9, when the top plate 100 is in the upright position, it is adapted to cover the latch part 341 and the latch receiving member 311 that are not covered by the fixed cover 410. A pair of cantilevered pin parts 421a are formed on the inner surfaces facing each other near the end of the movable cover side plate 421 on the opposite side to the fixed cover 410, and are rotatably attached to fitting holes 311c·312c formed in the latch receiving member 311 and the abutment surface member 312.

[0021] Here, as described above and shown in FIG. 6, the pin portion 421a formed on the movable cover side plate 421 arranged in the gap between the support member 310 and the leg 200 is set shorter than the pin portion 421a formed on the opposing movable cover side plate 421 as shown in FIG. 10. This makes it possible to keep the amount of opening of the movable cover side plate 421 small when the pin portion 421a is fitted into the fitting holes 311c and 312c of the latch receiving member 311 and the abutment surface member 312. Also, by setting such a shorter pin portion 421a as the pin portion 421a on the movable cover side plate 421 arranged in the gap between the support member 310 and the leg 200, the amount of opening of the movable cover side plate 421 is restricted after the support member 310 is attached to the leg 200, making it possible to make the movable cover 420 less likely to come off.

[0022] Further, a notch 422a is formed between the movable cover part 422 and the movable cover side plate 421 near where the pin part 421a on the leg 200 side is formed, making it easier to widen the interval between the pin parts 421a and to assemble it to the top board receiving member 320. Note that the notch is not limited to being formed in the movable cover part 422, but may be formed in the movable cover side plate 421 or in a part of the side where the movable cover side plate 421 and the movable cover part 422 are connected.

[0023] Also, pin portion 421b is formed on the inner surface near the end portion of movable cover side plate 421 on the fixed cover 410 side, and is slidably guided in guide groove 413. Here, as described above and as shown in Figs. 7 and 9, by providing at least one end portion of guide groove 413, for example the end portion closer to leg body 200, so that pin portion 421b can be inserted into guide groove 413 without widening the gap, and thus assembly of movable cover 420 can be facilitated.

[0024] The above folding table 1 can be stored in a small space by placing multiple folding tables 100 in an upright position close to each other. In particular, by providing each movable cover 420 so that it can abut against the top plate 100 of another folding table 1 in an upright position when the other folding table 1 is placed close to each other, the folding tables can be easily stored in a small space without damaging the top plate 100.

[0025] As described above, the latch receiving member 311 maintains the horizontal position and the upright position by engaging with the latch portion 341, and the abutment surface member 312 receives the load by abutting with the top plate receiving member 320 in the horizontal position, so that the thicknesses of the latch receiving member 311 and the abutment surface member 312 can be easily set separately. Therefore, the latch receiving member 311 can be easily formed by punching a steel plate, and the degree of freedom in setting the thickness of the abutment surface member 312 can be increased by aluminum die casting, so that the load from the top plate 100 can be reliably received, and the position of the top plate can be easily maintained more reliably. In addition, the degree of freedom in setting the distance from the top plate rotation shaft 330 to the abutment surface of the abutment surface member 312 and the size of the abutment surface can be increased without affecting the engagement operation by the latch portion 341. In addition, when the latch receiving member 311 is formed by a steel plate, it can be made easier to engage than an engagement portion that is tapered by a punching die.

[0026] Furthermore, by assembling the movable cover 420 to the tabletop receiving member 320, a guide groove 413 that guides the movable cover 420 in a slidable manner can be formed, so that the end of the movable cover 420 that covers the open portion of the tabletop receiving member 320 can be guided in a slidable manner while easily reducing manufacturing costs.

[0027] In the above example, the contact surface member 312 is made of aluminum die-casting, but the present invention is not limited to this and may be made of iron casting, resin injection, or a block member formed using a mold.

[0028] In addition, in the above example, the connecting member 210 is provided at a position offset from the tabletop pivot axis 330, for example at a position that does not engage with the side plate 322 of the tabletop receiving member 320, but this is not limited to the above, and the connecting member 210 may be provided coaxially with the tabletop pivot axis 330, for example by being inserted into a through hole formed in the side plate 322 of the tabletop receiving member 320.

[0029] In addition, in the above example, an example of a folding table having a pair of legs 200 was described, but this is not limited to the above. For example, a so-called single-pillar folding table may be configured in which two support members 310 are connected to one leg with a small distance between them. [Explanation of symbols]
