Japanese Patent No. 4111064

In the configuration described above, when a vertical load or force is applied to the top plate, the hanging wall on the top plate side and the standing wall on the leg side that are in contact with or close to each other are relatively displaced in the vertical direction. .. As a result, a shearing force perpendicular to the axial direction (insertion direction) of the insertion frame acts on the pin-shaped insertion frame inserted laterally into the engaging holes of the hanging wall and the standing wall. In particular, when the outer peripheral end of the top plate is provided so as to overhang laterally with respect to the legs and the overhang size of the top plate is large, when a vertical load or force acts on the outer peripheral end of the top plate, The moment due to this load or force increases, and a large shearing force acts on the insertion frame. For this reason, the insertion frame may be damaged, and the joint between the top plate and the leg may be broken.
An object of the present invention made in this regard is to provide a furniture which can enhance the coupling strength between an upper structure such as a top plate and legs.

The present invention adopts the following means in order to solve the above problems.
The furniture according to the present invention is formed on the leg, a leg that stands up on the floor, an upper structure that is supported by the upper portion of the leg, an upper structure side connecting portion that extends downward from the upper structure, and the leg. And a load receiving portion that receives a load of the upper structure by abutting at least one of the upper structure and the upper structure side connecting portion, and a side surface that is provided on the leg and faces the inner side of the upper structure side connecting portion . A leg-side connecting portion, a connecting member that presses and connects the upper structure-side connecting portion and the leg-side connecting portion to each other along a direction intersecting the side surface, and the legs are separated from each other in a predetermined direction. A pair of leg members that are arranged in a pair , and an upper connecting member that connects the pair of leg members to each other, and the upper structure-side connecting portion is above the upper connecting member, It is characterized by being placed in between .

According to this structure, the upper structure side connecting portion and the leg side connecting portion are pressed against each other by the connecting tool in a state where the load of the upper structure is supported by the legs by the load receiving portions formed on the legs. Since they are coupled, it is possible to suppress the shearing force that acts on the connector in the vertical direction. As a result, it is possible to prevent the connector from being damaged.

Further, in the furniture according to the present invention, in the above furniture, the leg-side connecting portion may be arranged more inward of the furniture than the upper structure-side connecting portion.
With this configuration, the leg-side connecting portion and the connecting portion between the leg-side connecting portion and the upper structure-side connecting portion are arranged inward of the furniture rather than the upper structure-side connecting portion, so that the connecting member is connected from the outside. Looking at the furniture, it will be hidden by the connection part on the superstructure side, improving the appearance.

Further, in the furniture according to the present invention, in the above furniture, the upper structure may be fixed to the upper structure side connecting portion side inside the furniture rather than the upper structure side connecting portion.
With this configuration, the fixed portion between the upper structure and the upper structure side connecting portion is also hidden inside the upper structure side connecting portion, and the appearance is improved.

Further, in the furniture according to the present invention, in the above-mentioned furniture, the upper structure side connecting portion has an outer surface facing the outside of the furniture, and the legs are arranged along the outer surface of the upper structure side connecting portion. A wall portion extending upward may be provided.

Further, in the furniture according to the present invention, in the above furniture, the load receiving portion may be an upper end portion of the wall portion configured to abut a lower surface of the upper structure.
With such a configuration, the upper end of the wall portion directly abuts the lower surface of the upper structure to support the load of the upper structure as the load receiving portion. As a result, the wall portion also serves as the load receiving portion, and the leg structure can be simplified.

Further, in the furniture according to the present invention, in the above furniture, the upper structure side connecting portion and the leg may be opposed to each other with a vertical gap.
In this way, in the structure in which the wall portion directly abuts the lower surface of the superstructure to support the load of the superstructure, a gap is formed between the superstructure-side connecting portion and the leg, so that the load of the superstructure is increased. It does not act on the leg via the structural side connection. In such a configuration, when a large load or force acts and the upper structure bends downward together with the upper structure side connecting portion, the gap is set so that the upper structure side connecting portion abuts on the leg. It is also possible to restrain the downward displacement due to the bending of the upper structure side connecting portion and transmit the load or force on the upper structure side to the leg.

Further, in the furniture according to the present invention, in the above furniture, a groove that is continuous in parallel with a lower surface of the upper structure is formed on the side surface of the upper structure side connecting portion, and one end portion of the connector is within the groove. May be locked to.
In this way, by locking the connecting tool using the groove formed in the upper structure-side connecting section, it is possible to increase the degree of freedom of the connecting position between the upper structure-side connecting section and the leg-side connecting section by the connecting tool. it can. Thereby, the position of the leg with respect to the superstructure can be easily changed within the range along the groove.

Further, in the furniture according to the present invention, in the above furniture, a plurality of the grooves are formed at intervals in the vertical direction, and one of the grooves is a connecting member for connecting the upper structure and the upper structure side connecting portion. One end may be locked and one end of the connector may be locked in the other groove.
With such a configuration, the degree of freedom of the connecting position between the upper structure and the upper structure-side connecting portion can be increased also for the connecting member. Furthermore, the connecting member and the connecting tool do not interfere in the same groove.

Further, in the furniture according to the present invention, in the furniture, the upper structure has a planar shape that is long in one direction in a plan view, and the upper structure-side connecting portion is arranged in the one direction along a lower surface of the upper structure. May be formed continuously.
With this structure, the upper structure that is long in one direction can be firmly supported by the upper structure-side connecting portion. Further, by using the upper structure side connecting portion functioning as a reinforcing element of the upper structure also for coupling with the leg side connecting portion, the number of members constituting the furniture can be suppressed.

According to the furniture according to the present invention, it is possible to increase the bonding strength between the upper structure such as the upper structure and the leg.

As shown in FIGS. 5 and 6, in the leg 20, a fixing bracket 24 for fixing the beam 40 is provided on the upper surface 22t of the upper connecting member 22. The fixing bracket 24 is provided along the upper surface 22t of the upper coupling member 22 with a base portion 25 fixed to the upper surface 22t with a bolt or the like (not shown), and a fixing wall extending upward from both ends of the base portion 25 in the first direction X. The (leg-side connecting portion) 26 is integrally formed.

As shown in FIG. 6, the fixed wall 26 rises upward from the end portion of the base portion 25 and is orthogonal to the lower flat surface portion 26a along the side surface 40a of the beam 40 and the upper end of the lower flat surface portion 26a. The orthogonal wall portion 26b extending in a direction away from the beam 40a, the seat surface portion 26c extending from the end of the orthogonal wall portion 26b in parallel to the side surface 40a of the beam 40, and the side surface 40a of the beam 40 orthogonal to the upper end of the seat surface portion 26c. A second orthogonal wall portion 26d extending in the direction of separation, a flat surface portion 26e extending parallel to the side surface 40a of the beam 40 from the end portion of the second orthogonal wall portion 26d, and a side surface of the beam 40 orthogonal to the upper end of the flat surface portion 26e. The third orthogonal wall portion 26f extending toward the 40a side and the upper flat portion 26g extending downward from the tip of the third orthogonal wall portion 26f along the side surface 40a of the beam 40 are integrally provided.
As described above, in the fixed wall 26, the lower flat surface portion 26a and the upper flat surface portion 26g that are orthogonal to the upper surface 22t are formed on the side facing the upper extension portion 21j of the leg member 21. Further, an insertion hole 26h is formed at a predetermined position in the seat surface portion 26c of the fixed wall 26.

A flat surface portion 21f is formed on the upper extension portion 21j of the leg member 21 on the side facing the fixed wall 26. In other words, the flat surface portion 21f faces the outer side surface 40s of the beam 40 that faces outward in the first direction X. The distance between the lower plane portion 26a and the upper plane portion 26g and the plane portion 21f is set to be slightly larger than the width dimension of the beam 40 in the first direction X.
In this way, the beam 40 is arranged between the fixed wall 26 and the flat surface portion 21 f of the leg member 21 at the portion of each leg 20.

Here, since the lower surface 30b of the top plate 30 directly abuts the upper end 21t of the leg member 21, the load of the top plate 30 is directly supported by the leg member 21.
Further, the lower surface 40b of the beam 40 fixed to the lower surface 30b of the top plate 30 via the mounting bracket 41 has a slight vertical gap C between the upper surface 22t of the upper connecting member 22 and the lower surface 40b.

The beam 40 is fixed to the fixed wall 26 by a seat member (coupling tool) 55 and a bolt (coupling tool) 56 with its side surface 40a abutting the lower flat surface portion 26a and the upper flat surface portion 26g of the fixed wall 26. There is. The seat member 55 has a female screw hole 55h and is inserted and arranged in the groove 42 below the beam 40. The bolt 56 is screwed into the female screw hole 55n of the seat member 55 in the groove 42 through the insertion hole 26h of the fixed wall 26. In this manner, the lower flat surface portion 26a and the upper flat surface portion 26g hit the side surface 40a of the beam 40, and the beam 40 and the fixed wall 26 are coupled to each other.

The table 10 configured as described above is provided on the plurality of legs 20 standing on the floor surface F, the top plate 30 supported on the tops of the plurality of legs 20, and the lower surface 30b of the top plate 30. Of the beam 40 protruding downward from the lower surface 30b of the leg 20, the upper end 21t of the leg member 21 formed on the upper surface of the leg 20 and receiving the load of the top plate 30 by hitting the lower surface 30b of the top plate 30, and the upper portion of the leg 20. Fixed wall 26 extending upward and extending along side surface 40a of beam 40, and bolt 56 and seat for connecting beam 40 and fixed wall 26 to each other by pressing them together in a direction orthogonal to side surface 40a. And a member 55.
With such a configuration, the beam 40 and the fixed wall 26 are pressed against each other by the bolt 56 and the seat member 55 to be coupled with each other while the load of the top plate 30 is supported by the upper ends 21t of the legs 20. Therefore, the vertical shearing force does not act on the bolt 56 and the seat member 55. As a result, the connection strength of the connection between the top plate 30 and the leg 20 by the beam 40 and the fixed wall 26 can be increased.

Further, the fixed wall 26 is arranged inside (inside) the table 10 with respect to the beam 40. With this configuration, the connecting portion between the fixed wall 26 and the beam 40 is arranged inside the table 10 with respect to the beam 40, so that when the table 10 is viewed from the outside, it is hidden by the beam 40. Is improved.

The top plate 30 is fixed to the beam 40 side inside the table 10 with respect to the beam 40. With this configuration, the fixed portion between the top plate 30 and the beam 40 is also hidden inside the beam 40, and the appearance is improved.

Further, the leg 20 includes an upper extension portion 21j extending upward so as to follow the outer surface 40s of the beam 40 that faces the outside of the table 10. With this configuration, a part of the beam 40 is hidden by the upper extension portion 21j of the leg 20, and the leg 20 and the top plate 30 can have an appearance as if they were integrated. Further, the beam 40 can be supported from the outside by having the upper extending portion 21j of the leg 20 along the outside of the beam 40.

In addition, the upper extension portion 21j of the leg 20 abuts the lower surface 30b of the top plate 30 to form a load receiving portion that supports the load of the top plate 30. As a result, the upper extension portion 21j of the leg 20 has both a function of covering a part of the beam 40 and a function of a load receiving portion, and the configuration of the leg 20 can be simplified.

Further, the beam 40 and the leg 20 face each other with a gap C in the vertical direction. With such a configuration, in the normal state, the load of the top plate 30 does not act on the leg 20 via the beam 40. When the top plate 30 bends downward together with the beam 40 due to a large load or force, the beam 40 collides with the leg 20 to restrain the downward displacement of the beam 40 due to the deflection, and thus the load of the top plate 30. The force can be transmitted to the leg 20. As a result, the portion of the leg 20 that receives the load or force of the top plate 30 increases, and the load or force supported by the leg 20 can be dispersed.

Further, on the side surface 40a of the beam 40, a groove 42 that is continuous in parallel with the lower surface 30b of the top plate 30 is formed, and is locked in the seat member 55 and the groove 42 that are fastened to the bolt 56. In this way, the degree of freedom of the connecting position between the beam 40 and the fixed wall 26 by the bolt 56 and the seat member 55 can be increased. Thereby, the position of the leg 20 with respect to the top plate 30 can be easily changed within the range along the groove 42.

Further, a plurality of grooves 42 are formed at intervals in the vertical direction, and a bolt 51 that connects the top plate 30 and the beam 40 and a seat member 52 that is one end of the seat member 52 are locked in one groove 42. The bolt 56 and the seat member 55 that is one end of the seat member 55 are locked in the other groove 42. With such a configuration, it is possible to increase the degree of freedom of the connecting position between the top plate 30 and the beam 40 for the bolt 51 and the seat member 52 as well. Further, the bolt 51 and the seat member 52 do not interfere with the bolt 56 and the seat member 55 in the same groove 42.

The top plate 30 has a planar shape in which the second direction Y is the longitudinal direction and the first direction X is the lateral direction in the horizontal plane, and the beam 40 is provided on the lower surface 30b of the top plate 30. It is continuously provided along the longitudinal direction. With this configuration, the top plate 30 that is long in one direction can be reinforced by the beam 40 and firmly supported. Further, by using the beam 40 functioning as a reinforcing element of the top plate 30 also for coupling with the fixed wall 26, the number of members constituting the table 10 can be suppressed.

Further, in the table 10, as shown in FIG. 4, the width dimension W1 of the leg 20 when viewed from the first direction X is gradually increased from the lower side to the upper side, so that the upper portion of the leg 20 is lifted. It is possible to secure the strength at the joint portion with respect to the plate 30. Further, in the lower part of the leg 20, the width W2 of the leg 20 becomes small, so that it is possible to suppress the interference between the leg of the user and the leg 20.
Further, as shown in FIG. 3, the width dimension W2 of the leg 20 when viewed in the second direction Y is gradually increased from the upper side to the lower side, so that the upper portion of the leg 20 is the top plate 30 of the top plate 30. Since it is located inward in the direction X, it is possible to secure a wide upper space near the top plate 30. Therefore, the knees of the user's lower limbs are less likely to interfere with the legs 20. With such a configuration, the lower limb accommodation space Sp below the top plate 30 can be secured while securing the strength.

Here, the first direction X is the lateral direction of the top plate 30, and the second direction Y is the longitudinal direction of the top plate 30. With such a configuration, the leg 20 has a high strength at the joint portion with respect to the top plate 30 against a load and a force in the second direction Y of the top plate 30 which is the second direction Y and the vertical direction. Becomes Further, in the leg 20, the lower limb of the user who faces the top plate 30 from the lateral direction of the top plate 30 which is the first direction X is less likely to interfere with the upper portion of the leg 20.
By the way, in the top plate 30 having a shape elongated in one direction as described above, in general, the number of users facing the top plate 30 on the long side 30p along the longitudinal direction (second direction Y) is short. The short side 30q along the (first direction X) is larger than the number of users facing the top plate 30. That is, the first direction X is the direction facing the top plate 30 from the side with the most use, and the second direction Y is the direction facing the top plate 30 from the side with the least use. As a result, when viewed from the side where the top plate 30 is frequently used, the lower limbs of the user who face the top plate 30 are less likely to interfere with the legs 20.

Further, the first direction X is a direction in which the top plate 30 faces the leg 20 from the side where the overhang dimension H2 is laterally small, and the second direction Y is the top direction with respect to the leg 20. This is the direction in which the plate 30 faces directly from the side where the overhang dimension H1 that projects laterally is large. Since the width dimension W1 of the leg 20 when viewed from the first direction X gradually increases from the lower side to the upper side of the leg 20, the load and the force in the second direction Y and the up-down direction are The joint portion with the top plate 30 has high strength. Therefore, the leg 20 can effectively exert its strength against a load or force applied to a portion of the top plate 30 having a large overhang dimension H2.

Further, in the table 10, each leg 20 is provided so as to be inclined so that the interval between the pair of legs 20 facing each other along the second direction Y gradually increases from the upper side to the lower side. .. With such a configuration, a force in the direction in which the pair of legs 20 spreads in the second direction Y acts due to the load acting on the top plate 30. Since the width dimension W1 of the leg 20 when viewed from the first direction X gradually increases from the lower side to the upper side of the leg 20, the load and the force in the second direction Y and the up-down direction are The joint portion with the top plate 30 has high strength. Therefore, in the configuration in which the distance between the pair of legs 20 gradually increases from the upper side to the lower side, the legs 20 are unlikely to spread in the second direction Y, and high strength can be exhibited.
