Description

The present invention relates to a folding table with foldable legs.

A table with a top and legs, the legs of which can be folded, is disclosed in the following patent documents 1 and 2.

JP 2020-68967 A Utility Model Registration No. 3093054

Conventional folding tables have a problem with wobbling when placed outdoors on uneven ground because the legs are not sufficiently fixed, especially along the length of the tabletop.

The objective of the present disclosure is to provide a folding table whose legs can be sufficiently fixed and whose wobbling can be reduced even when the table is placed on uneven ground outdoors.

The folding table according to the embodiment of the present disclosure is characterized by comprising a tabletop, foldable legs that support the underside of the tabletop, and a stay that is connected at one end to the underside of the tabletop and at the other end to the legs, and that can be extended or retracted as the legs are opened or closed and can be fixed at any length.

With the above configuration, when the legs are opened relative to the tabletop, it is possible to fine-tune the length of the stays as desired depending on how the tips of the legs touch the ground. This allows the legs to be fixed in a taut state relative to the tabletop by the stays, reducing the wobble of the legs relative to the tabletop. By adjusting and fixing the length of the stays, the legs of the folding table of the present disclosure can be maintained at any angle between the folded state and the fully opened state. This makes it possible to set the tabletop so that it is leaning against the ground at any angle.

In addition, in the above folding table, it is preferable that the stay comprises an outer member having a hollow rod shape and one end of which is rotatably connected to one of the tabletop or the leg, an inner member having a rod shape that is slidably inserted into the outer member and one end of which is rotatably connected to the other of the tabletop or the leg, and a locking member that is provided on the other end of the outer member and can fix the inner member at any position.

With the above configuration, both ends of the stay can rotate freely depending on the degree to which the legs are opened, while the locking member can fix the inner member, which can move in and out of the outer member, at any position. This makes it possible to appropriately fix the position of the legs with the stay depending on the condition of the installation surface of the folding table, reducing rattling.

Furthermore, in the folding table, it is preferable that the legs include an upper leg member formed in a hollow rod shape with one end rotatably connected to the tabletop, a lower leg member formed in a rod shape that is slidably inserted into the upper leg member, and a leg lock member provided on the other end of the upper leg member and capable of fixing the lower leg member at any position.

The above configuration makes it possible to freely adjust the length of each leg even if the surface on which the folding table is placed is inclined.

In addition, in the folding table, the leg locking member includes a leg cover member attached to cover the outer periphery of the other end side of the upper leg member, and a locking flange protruding inward from the opening on the lower end side of the leg cover member, and a guide member is attached to the outer surface of the upper end of the lower leg member, and it is desirable that the width of the lower leg member including the guide member exceeds the width of the opening on the lower end side of the leg cover member.

By configuring it as described above, while the length of the leg is being adjusted, the guide member of the lower leg member comes into contact with the locking flange when the upper leg member is not fixed to the lower leg member, thereby preventing the lower leg member from falling any further.

Furthermore, in the above folding table, it is desirable that the inner surface of the upper leg member is provided with a pair of ribs that protrude inwardly and parallel to each other along the longitudinal direction and have a regulating rail portion spaced apart enough to accommodate the width of the guide member.

With the above configuration, the guide member slides between the regulating rails, allowing the lower leg member to slide smoothly against the upper leg member. In addition, when the folding table is placed on the ground, rattling between the upper and lower leg members is also reduced.

Since the embodiment of the present disclosure is configured as described above, a folding table is provided in which the legs can be sufficiently fixed and wobbling can be reduced even when the table is placed on uneven ground outdoors.

An embodiment of the folding table 1 of the present disclosure will be described with reference to the drawings. In the following description, when "upper side" and "lower side" are mentioned, the up and down directions are defined based on the installed state. Furthermore, reference numerals commonly used in each drawing indicate the same parts or components even if they are not mentioned in the description of each drawing. Furthermore, the materials of each component mentioned below are examples and are not limited to these.

Figure 1 shows a front view of the folding table 1 of this embodiment in a state of use where the legs 20 are opened and extended and placed on the installation surface indicated by the two-dot chain line in the figure. The legs 20 are foldable and support the underside of the tabletop 10. A stay 30 is provided between the tabletop 10 and the legs 20. One end of the stay 30 is connected to the underside of the tabletop 10, and the other end of the stay 30 is connected to the legs 20. The stay 30 can be expanded and contracted as the legs are opened and closed, and can be fixed at any length. In the state shown in Figure 1, the stay 30 is fixed in an extended state. From the state shown in Figure 1, when the legs 20 are shortened and closed while the stay 30 is shortened, the legs 20 are folded and stored as shown in Figure 2.

Figure 3 shows a top perspective view of the folding table 1 with the legs 20 open. The table top 10 has a shape in which a narrow side edge 12 surrounds the periphery of a roughly rectangular top surface 11. The legs 20 are provided on the underside of each of the short sides of the table top 10. Each leg 20 has two legs 21.

Figure 4A shows the folding table 1 of Figure 3 in a bottom perspective view. Figures 4B, 4C, and 4D are enlarged views of the portions shown in circles B, C, and D, respectively. Three metal frames are provided on the underside of the tabletop 10 to connect the inner surfaces of the side edges 12 on the long sides, with the central one being the central support frame 13 and the two near the short sides being edge support frames 14. Two wide leg connection frames 15 are connected in parallel between both ends of the central support frame 13 and one edge support frame 14. Two narrow leg connection frames 16 are connected in parallel between both ends of the central support frame 13, slightly closer to the center, and the other edge support frame 14. The wide leg connection frames 15 and narrow leg connection frames 16 are also made of metal.

The two legs 20 each have a different distance between the two legs 21. The wider leg 20A is the wider leg, and the narrower leg 20B is the narrower leg. The two legs 21 of the leg 20 are connected by two horizontal members 22. Each of the four legs 21 includes an upper leg member 24 formed in a hollow rod shape, a lower leg member 25 formed in a rod shape that is slidably inserted into the upper leg member 24, and a leg lock member 26 provided at the lower end, which is the other end side, of the upper leg member 24, and capable of fixing the lower leg member 25 at any position. The upper leg member 24, the lower leg member 25, and the horizontal members 22 are all made of metal.

The two legs 21 of the wide leg 20A are each rotatably connected to the tabletop 10 at the upper end of the upper leg member 24 at the edge of the wide leg connecting frame 15 via a metal hinge member 23 (see FIG. 4B). Similarly, the two legs 21 of the narrow leg 20B are each rotatably connected to the tabletop 10 at the upper end of the upper leg member 24 at the edge of the narrow leg connecting frame 16 via a hinge member 23. The hinge members 23 of each of the four legs 21 are covered from the outside by a synthetic resin leg cover member 17 attached to the edge support frame 14. In addition, a marker tape 28 is wound around the outer periphery of the lower leg member 25 of each of the four legs 21, which serves as a guide for the length to pull out the lower leg member 25 from the upper leg member 24. Additionally, a synthetic resin tip cap 27 is attached to the lower end of each lower leg member 25.

The central support frame 13 and the upper horizontal members 22 of each leg 20 are connected by stays 30. The stays 30 include an outer member 31 formed in a hollow rod shape, an inner member 32 formed in a rod shape that is slidably inserted into the inside of the outer member 31, and a locking member 33 provided on the outer member 31 and capable of fixing the inner member 32 at any position. Both the outer member 31 and the inner member 32 are made of metal.

The lower end portion, which is one end of the outer member 31, is rotatably connected to the center portion of the cross member 22 of the leg 20 via a metal leg-side hinge 38 (see FIG. 4C). Meanwhile, the upper end portion, which is one end of the inner member 32, is rotatably connected to the center portion of the central support frame 13 of the tabletop 10 via a metal tabletop-side hinge 37 (see FIG. 4D). The locking member 33 is provided at the other end, which is the upper end portion, of the outer member 31.

Figure 5 shows an oblique view of the stay 30 disassembled. A leg side hinge 38 is attached to the lower end of the outer member 31, and a locking member 33 is attached to the open end of the upper end portion. Meanwhile, a top plate side hinge 37 is attached to the upper end of the inner member 32, and the lower end portion is inserted into the open end of the outer member 31 to which the locking member 33 is attached.

Figure 6 shows a perspective view of the locking member 33 in an exploded state. The locking member 33 is composed of a synthetic resin cover member 34, a metal pressing operation member 36, and a pressing member 35 made of a different metal. The cover member 34 has a through-hole 34C that penetrates the openings at both ends, a pair of support plates 34D that protrude from one surface of the outer periphery, an axial hole 34E that penetrates the support plate 34D in the width direction, and a pressing hole 34F that penetrates the one surface between the support plates 34D. The pressing member 35 has a shape in which two regular square prisms with different side lengths are stacked with the same center. Of the two regular square prisms, the one with the longer side length is the pressed part 35A, and the one with the shorter side length is the pressing part 35B. The pressing part 35A of the pressing member 35 is accommodated in the accommodation part 34H provided between the support plates 34D and 34D. The pressing portion 35B of the pressing member 35 is inserted into the pressing hole 34F that communicates with the storage portion 34H. The pressing operation member 36 is composed of a substantially cylindrical shaft support portion 36D and an operation portion 36E that extends from a part of the side surface of the shaft support portion 36D. The shaft support portion 36D is provided with a shaft hole 36C that is a through hole in the width direction. A separate cylindrical sliding pin 36B (made of a different metal than the pressing operation member 36) is embedded near the shaft hole 36C. The operation portion 36E has a substantially plate-like structure with a non-uniform thickness, with the thickness being greatest in the middle portion. In the mountain-shaped portion where the thickness is greatest, the side surface on the side of the shaft hole 36C is carved out to form an engagement groove 36A.

The state in which the outer member 31, the inner member 32, and the lock member 33 are assembled is shown in the cross-sectional view of FIG. 7A. FIG. 7A shows a state in which the outer member 31 and the inner member 32 are not fixed (unfixed state) in the stay 30 in a cross-sectional view along the axis. The upper end of the outer member 31 is inserted from the side (here, the "lower end side") of the cover member 34 where the pressing hole 34F (see FIG. 6) is provided. The upper end of the outer member 31 is fixed by the blind rivet 34B when it abuts against the locking flange 34G protruding inward at the upper end side of the through portion 34C (see FIG. 6) and cannot be inserted any further. On the other hand, the lower end of the inner member 32 is inserted from the upper end side opposite to the lower end side. In addition, a fixing hole 31A is provided on the side of the outer member 31 facing the accommodation portion 34H. Then, the pressing member 36 is attached to the cover member 34 with the pressed portion 35A of the pressing member 35 housed in the housing portion 34H and the pressing portion 35B of the pressing member 35 inserted into the pressing hole 34F. That is, the shaft hole 36C of the pressing member 36 is aligned with the shaft hole 34E of the cover member 34, and then the rotating shaft 36F is inserted and fixed. In the non-fixed state, the pressing member 35 is not pressed against the inner member 32, so the inner member 32 can freely appear and disappear from the outer member 31. Furthermore, a locking claw 34A is provided to protrude upward between the support plates 34D on the lower end side of the cover member 34.

When the inner member 32 is pulled out by an arbitrary length from the state shown in FIG. 7A, the pressing member 36 is rotated right on the drawing, and the stay 30 is in the fixed state shown in the cross-sectional view of FIG. 7B. In FIG. 7B, an enlarged view of the part indicated by the circle C is shown in FIG. 7C. At the moment of reaching this fixed state, the locking claw 34A of the cover member 34 fits into the locking groove 36A of the rotating pressing member 36 (see FIG. 7C), and at this time, a clicking sound is generated due to friction between the members, giving the user a sense of operation. In this state, the vicinity of the part where the sliding pin 36B is provided in the pivot support part 36D of the pressing member 36 presses the pressure receiving part 35A of the pressing member 35, and the pressing part 35B presses the inner member 32 through the fixing hole 31A of the outer member 31, so that the inner member 32 is maintained in a fixed state relative to the outer member 31. The sliding pin 36B improves the sliding properties when the pressing operation member 36 comes into contact with the pressing member 35.

Figure 8A is a partial front view of the leg 21 in an extended state. Figure 8B is a partial front view of the leg 21 in a retracted state. The leg 21 can be freely extended and retracted between the maximum length shown in Figure 8A and the minimum length shown in Figure 8B, up to the unlocked state of the leg locking member 26, and the leg lower member 25 can be locked at any length between these lengths by locking the leg locking member 26.

Figure 9 is a perspective view showing the upper end portion of the lower leg member 25. The lower leg member 25 is a long metal member. Its cross section is roughly rectangular, and a metal guide member 25A with a U-shaped cross section is attached along the longitudinal direction to the outer surface of the upper end, in other words, both long side surfaces, and is fixed in place with blind rivets 25A1. In addition, a rivet avoidance groove 25B, which is a groove fitted inward, is provided on one of the sides on which the guide member 25A is not provided.

The upper leg member 24 is also a long metal member. Figure 10A shows a cross section of the upper leg member 24 perpendicular to the axis. The upper leg member 24 has a generally rectangular cross section, and on both inner surfaces of the long sides, there are provided restricting rail portions 24A, which are a pair of ridges that protrude inward in parallel and are spaced apart by a distance that can accommodate the width of the guide member 25A.

Figure 10B shows a cross-sectional view perpendicular to the axis of the state in which the lower leg member 25 is housed in the upper leg member 24. The guide member 25A of the lower leg member 25 is housed between the regulating rail portions 24A and can slide up and down along the regulating rail portions 24A. As shown in Figure 10B, the lower leg member 25 has a clearance with respect to the upper leg member 24, but the guide member 25A is regulated by the regulating rail portions 24A, allowing the lower leg member 25 to slide smoothly against the upper leg member 24. The guide member 25A may be provided on only one side, in which case the regulating rail portion 24A may also be provided on only the corresponding one side.

Figure 11 shows a perspective view of the leg locking member 26 in an exploded state. The leg locking member 26 is composed of a synthetic resin leg cover member 26A, a metal leg pressing operation member 26C, and a different metal leg pressing member 26B. The leg cover member 26A has a through-hole 26A3 that penetrates the openings at both ends, a pair of support plates 26A4 that protrude from one surface of the outer periphery, an axial hole 26A5 that penetrates the support plate 26A4 in the width direction, and a pressing hole 26A6 that penetrates the one surface between the support plates 26A4 and 26A4. The leg cover member 26A is a member that is attached so as to cover the outer periphery of the lower end side of the leg upper member 24. The leg pressing member 26B has a shape in which two regular square prisms with different side lengths are stacked with the same center. Of the two square prisms, the one with the longer side is the pressure receiving portion 26B1, and the one with the shorter side is the pressing portion 26B2. The pressure receiving portion 26B1 of the leg pressing member 26B is received in the storage portion 26A8 provided between the support plates 26A4 and 26A4. The pressing portion 26B2 of the leg pressing member 26B is inserted into the pressing hole 26A6 communicating with the storage portion 26A8. The leg pressing operation member 26C is composed of a substantially cylindrical shaft support portion 26C4 and an operation portion 26C5 extending from a part of the side surface of the shaft support portion 26C4. The shaft support portion 26C4 is provided with a shaft hole 26C3 which is a through hole in the width direction. A cylindrical sliding pin 26C2 (made of a different metal from the leg pressing operation member 26C) which is a separate member is embedded near the 26C3. The operating section 26C5 has a generally plate-like structure with a non-uniform thickness, with the thickness greatest in the middle section. In the mountain-shaped section where the thickness is greatest, the side facing the shaft hole 26C3 is carved out to form an engagement groove 26C1.

The state in which the upper leg member 24, the lower leg member 25, and the leg lock member 26 are assembled is shown in the cross-sectional view of FIG. 12A. FIG. 12A shows the state in which the upper leg member 24 and the lower leg member 25 are not fixed (unfixed state) in the leg 20 in a cross-sectional view along the axis. The lower end of the upper leg member 24 housing the lower leg member 25 is inserted from the side (herein referred to as the "upper end side") of the leg cover member 26A where the pressing hole 26A6 (see FIG. 11) is provided. When the lower end of the upper leg member 24 abuts against the locking flange 26A7 protruding inward at the lower end side of the through portion 26A3 (see FIG. 11) and cannot be inserted any further, only the upper leg member 24 is fixed to the leg cover member 26A by the blind rivet 26A2. At this time, the blind rivet 26A2 enters the rivet avoidance groove 25B (see FIG. 9), so the blind rivet 26A2 does not interfere with the leg lower member 25. Furthermore, a fixing hole 24B is provided on the side of the leg upper member 24 facing the accommodation portion 26A8. Then, with the pressed portion 26B1 of the leg pressing member 26B accommodated in the accommodation portion 26A8 and the pressing portion 26B2 of the leg pressing member 26B inserted into the pressing hole 26A6, the leg pressing operation member 26C is attached to the leg cover member 26A. That is, after aligning the shaft hole 26C3 of the leg pressing operation member 26C with the shaft hole 26A5 of the leg cover member 26A, the rotating shaft 26C6 is inserted and fixed. In the non-fixed state, the leg pressing member 26B is not pressed against the leg lower member 25, so the leg lower member 25 can freely move in and out of the leg upper member 24. Furthermore, a locking claw 26A1 protrudes downward between the support plates 26A4 on the lower end side of the leg cover member 26A.

When the leg lower member 25 is pulled out to an arbitrary length from the state shown in Fig. 12A, the leg pressing member 26C is rotated to the right in the drawing, and the leg 21 enters the locked state shown in the cross-sectional view of Fig. 12B. At the moment this locked state is reached, the locking claw 26A1 of the leg cover member 26A fits into the locking groove 26C1 (see Fig. 12A) of the rotating leg pressing member 26C, and at this time a clicking sound is generated by the friction between the members, giving the user a feeling of operation. In this state, the vicinity of the portion where the sliding pin 26C2 is provided on the pivot support portion 26C4 of the leg pressing operation member 26C presses the pressure-receiving portion 26B1 of the leg pressing member 26B, and the pressing portion 26B2 presses the leg lower member 25 through the fixing hole 24B of the leg upper member 24, thereby maintaining the leg lower member 25 fixed to the leg upper member 24. The sliding pin 26C2 improves the sliding property when the leg pressing operation member 26C comes into contact with the leg pressing member 26B.

Figure 13 shows the leg lock member 26 from above with the upper leg member 24 and the lower leg member 25 inserted. However, the upper leg member 24 and the lower leg member 25 are shown in cross section. The leg pressing member 26B and the leg pressing operation member 26C are omitted. The lower end of the through-hole 26A3 (see Figure 11) of the leg cover member 26A is formed with the locking flange 26A7 that protrudes inward as described above. The portion of the locking flange 26A7 that corresponds to the guide member 25A protrudes further inward, so that the guide member 25A abuts against the protruding portion. In other words, the width W1 of the lower leg member 25 including the guide member 25A exceeds the width of the opening on the lower end side of the leg cover member 26A, i.e., the width W2 between the edges of the locking flange 26A7. As a result, even in an unfixed state, the lower end of the guide member 25A abuts against the locking flange 26A7, preventing the leg lower member 25 from falling off the leg lock member 26. When the guide member 25A is provided on only one side, the portion of the locking flange 26A7 that corresponds to the guide member 25A may also be provided on only the corresponding side.

Figure 14 shows a top perspective view of the folding table 1 with the legs 20 folded. In this figure, the top surface 11 that contacts the surface of the top plate 10 can be seen. In addition, a handle 18 for carrying is provided in the center of the side edge 12 on the long side.

Figure 15A shows a bottom perspective view of the folding table 1 with the legs 20 folded. In this view, the underside of the tabletop 10 is visible. In this state, both stays 30 are in their most contracted state. Each of the pair of legs 20 is also folded into a position in contact with the underside of the tabletop 10, with the lower leg member 25 housed in the upper leg member 24. In this state, the narrow leg 20B is housed between the wide leg members 20A.

When the legs 20 are folded, the distance from the top surface 11 of the tabletop 10 to the bottom end of the leg cover member 17 is greater than the distance from the top surface 11 to the side of the legs 20. Therefore, when the folding table 1 with the legs 20 folded is placed on the floor with the tabletop 10 facing up, as shown in FIG. 2, the leg cover member 17 comes into contact with the installation surface indicated by the two-dot chain line in the figure, so that the legs 20 are prevented from coming into contact with the installation surface, reducing the possibility of damage to the legs 20.

Furthermore, as shown in FIG. 15B, which is an enlarged view of the portion indicated by circle B, the hinge member 23 installed at the upper end of the upper leg member 24 is formed in a state in which it is tilted inward by 10° when the leg 20 is folded. Therefore, when the leg 20 is in an open state, the leg 20 is erected on the installation surface in a state in which it is tilted outward by 10° with respect to the vertical line (see FIG. 1).

When setting up the folding table 1 of this embodiment, first, from the upside-down state shown in FIG. 15A, the locking members 33 of both stays 30 are unlocked (see FIG. 7A), and then the pair of legs 20 are rotated outward until the hinge members 23 abut against the edge support frame 14. Next, the leg locking members 26 of each of the four legs 21 are unlocked (see FIG. 12A), and the lower leg members 25 are extended to lock the leg locking members 26 at the desired length (see FIG. 12B). In this state, the table is turned over so that the legs 20 face downward, and the tips of the legs 20 come into contact with the installation surface as shown in FIG. 1.

In this state, the degree to which the legs 20 are opened can be finely adjusted depending on the condition of the installation surface. The extended state of the stays 30 can be adjusted until they become tension rods, and the locking member 33 can then be fixed (see FIG. 12B) to maintain the degree to which the legs 20 are opened. This reduces wobbling of the legs 20. Furthermore, not only can the length of the legs 20 be adjusted depending on the application or the physique of the user, but when installing on a sloping surface, it is also possible to adjust the length of each of the four legs 21 so that the tabletop 10 is horizontal.

In the present embodiment, the legs 20 of the folding table 1 can be maintained at any angle between the folded state shown in FIG. 2 and the maximum open state shown in FIG. 1 by adjusting and fixing the length of the stays 30. In addition, since the length of each leg 21 can be freely adjusted, it is also possible to install the top plate 10 so that it stands at any angle, as shown in FIG. 16A. With this installation method, the top plate 10 of the folding table 1 can also be used as a standing signboard. At this time, as shown in FIG. 16B, which is an enlarged view of the portion indicated by circle B in FIG. 16A, the hinge member 23 of the upper leg 20 is maintained at an angle slightly open from the folded state. On the other hand, as shown in FIG. 16C, which is an enlarged view of the portion indicated by circle C in FIG. 16A, the hinge member 23 of the lower leg 20 is maintained at an angle slightly closed from the erected state. The unstable angle of the hinge member 23 as shown in FIG. 16B and FIG. 16C can be maintained by adjusting and fixing the length of the stays 30.

As described above, the folding table 1 of this embodiment can be set up with the legs 20 spread apart appropriately depending on the conditions of the installation surface by adjusting and fixing the length of the stays 30. Since it is particularly suitable for installation on uneven ground such as outdoors, it is suitable for use as a podium for spreading out documents such as drawings and maps at construction sites or disaster relief sites.
