If the leg structure is a sleeve type or a side plate type, the top plate can be easily fixed to the leg structure. As shown in FIG. 1, a plate is provided at the upper end of each leg, and this plate is fixed to the lower surface of the top plate, thereby firmly fixing the top plate and the leg.
JP2002-125766

  By the way, there is furniture with a top plate that supports the top plate so that it can slide back and forth for the purpose of opening the wiring space under the top plate, etc. Under this structure, the top plate is fixed to the leg structure. Can not do it. In particular, when the leg structure is to be realized as a support column type, it is indispensable to firmly connect the legs with a frame member to ensure the independence and strength as the leg structure. However, when there is a situation in which the left and right front legs cannot be connected by a frame member, for example, when a center drawer is provided, the front leg is cantilevered by a frame member that connects the front leg and the rear leg. There is a problem that the front leg is likely to open in the shape of a letter C in front view or to be distorted into a parallel link at a normal use position where a load is applied to the top board.

  The present invention has been made paying attention to such a problem, and even if the leg structure is composed of a support-type leg, the top plate is slid back and forth without unduly reducing the mounting strength of the leg. It is an object of the present invention to newly provide furniture with a top plate that can be effectively used even when the leg structure is of another type.

  In order to achieve this object, the present invention takes the following measures.

  That is, according to the present invention, in the furniture with a top plate in which the top plate slides back and forth with respect to the leg structure, when the top plate moves rearward to the normal use position, the front end side of the top plate is The front end portion of the leg structure is engaged with the front end portion of the leg structure to prevent the front end portion from tilting in the width direction with the upper end portion as a fulcrum.

  In such a case, as long as the top plate is engaged with the leg structure, an effect equivalent to or equivalent to that of fixing the top plate to the leg structure can be obtained. Even if the structure is employed, it is possible to effectively prevent a phenomenon in which the front end portion of the leg structure opens in a C shape in front view or is distorted in a parallel link shape at the normal use position.

  In order to achieve a sufficient engagement state, the engaged portion is provided above the upper end of the leg structure, and the engaged portion provided on the lower surface of the top plate is engaged with the engaged portion. It is desirable to make it.

  In order to ensure sufficient mounting strength without creating an undue gap between the top plate and the leg structure, the shape of the engaged portion or the shape of the periphery of the engaged portion must be It is preferable to have a plate shape that fits in the gap between the plates. For the same reason, it is preferable that the shape of the engaging portion or the shape of the periphery of the engaging portion is a plate shape that is attached to the lower surface on the front end side of the top plate and fits in the gap between the leg structure and the top plate. .

  In order to effectively increase the deterrence force due to the engagement of the engaging portion and the engaged portion against the tilting of the leg structure, the engagement dimension along the width direction of the top plate is the width dimension of the leg structure. It is desirable that the length is set longer than that.

  In order to make the engagement simple and reliable, either the engaged portion of the leg structure or the engaging portion of the top plate has a protrusion protruding in the sliding direction of the top plate, and the other is the protrusion. It is effective to form a substantially rectangular recess that accepts.

  INDUSTRIAL APPLICABILITY The present invention is extremely useful when applied to furniture with a top plate of a leg structure having independent strut-type legs in front, rear, left, and right. In particular, the leg structure is between the front leg and the rear leg and between the rear leg. The effect is great when applied to furniture with a top plate, which is a structure in which the front legs are connected to each other by a frame member. Such a structure is extremely suitable as a structure in which a center drawer that fits within the thickness dimension of the frame member is provided between the front legs.

  Since the present invention is configured as described above, even if the leg structure is composed of support-type legs, the structure in which the top plate is slid forward and backward without unduly reducing the mounting strength of the legs is effectively employed. This makes it possible to provide a new and useful furniture with a top plate.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The furniture with a top plate of this embodiment, as shown in FIGS. 1 to 3, allows the leg structure 1 to support the top plate 2 and the center drawer 3, which are movable bodies, so that they can slide independently of each other. It is a thing.

  Specifically, as shown in FIGS. 4 and 5, the leg structure 1 connects the left and right leg elements 1 a and 1 a with a rear horizontal member 11 and an intermediate horizontal member 12, and a front horizontal member. The leg element 1a has a gate shape in which the front leg 13a and the rear leg 13b that are paired in the front-rear direction are connected by the side frame member 14. The rear horizontal member 11 and the side horizontal member 14 have a frame member F1 having a horizontal groove f that continuously opens inward along the longitudinal direction, and the intermediate horizontal member 12 continues to both sides along the longitudinal direction. A frame member F2 having an open horizontal groove f is used. As shown in FIG. 7 and the like, the groove width fx of the horizontal groove f is slightly narrower than the vertical inner dimension FX of the hollow portion formed inside the frame members F1 and F2, and A nut member 8 (see FIG. 18), which will be described later, can be locked on the inner surface.

  The top plate 2 is a thin plate having a thickness dimension of about 10 mm, and two movable rollers 20 as movers are arranged in a horizontal groove f continuously opened inside the side frame member 14 as shown in FIG. The first movable bracket 21 and the second movable bracket 22 are attached to the support shaft of the movable roller 20, and the intermediate portion and the rear edge portion of the top plate 2 are mounted on the top plate mounting surface formed above these movable brackets 21 and 22. Is fastened. Both the movable brackets 21 and 22 hold the horizontal state of the top plate mounting surface by inserting convex portions 21a and 22a provided on a part thereof between the upper and lower edges of the horizontal groove f. Then, the top plate 2 is slid forward as shown in FIGS. 2 and 7, and the front slide position 2F where the back region 1B of the leg structure 1 is opened upward, as shown in FIGS. It is possible to move between a rear slide position 2B (normal use position) that slides backward and closes the back area 1B. At that time, the lower surface of the front edge side is supported by the first fixed roller 23 which is a front edge side support provided on the side frame member 14, and the front slide position 2F shown in FIG. 7 and the rear slide shown in FIG. The lower surface on the front edge side of the top plate 2 is backed up between the position 2B. Further, the top plate 2 is attached to a second fixed roller 24, which is an intermediate support body provided with the lower surface of the central portion on the intermediate horizontal member 12, as shown in FIG. 4, in order to prevent bending of the central portion in the width direction. The lower surface of the center part of the top plate 2 is backed up between the front slide position 2F shown in FIG. 9 and the rear slide position 2B shown in FIG. 10 to prevent its bending.

  Accordingly, on the top plate 2, a first latch member 41 for locking to the front slide position 2F shown in FIG. 12 and a second latch member 42 for locking to the rear slide position 2B shown in FIG. And a third latch member 43 for locking to the intermediate slide position 2M shown in FIG. 13, and the top plate 2 is in the state of FIGS. 7 and 8 in the front slide position 2F and the rear slide position 2B. Engaging structures 51 and 52 that restrict the vertical movement of the front edge side of the top plate 2 are employed, and the top plate 2 is in the state of FIGS. 9 and 10 with the top plate 2 at the front slide position 2F and the rear slide position 2B. Restriction portions 61 and 62 for restricting the vertical movement on the rear edge side are provided.

  The latch members 41, 42, 43 are provided at three locations along the depth direction of the top plate 2, and the latch members 41, 42, 43 are forwarded and returned to the outer surface of the intermediate horizontal member 12 at a predetermined movement position. The top plate 2 is brought into contact with a predetermined movement position.

  As shown in FIGS. 11 to 17, these latch members 41, 42, and 43 are in the form of a balance attached around the support shaft m, and the intermediate horizontal member 12 has a first contact perpendicular to the moving direction. In the normal posture elastically biased by a spring 44c, which will be described later, in association with the formation of a substantially square pipe having the upright surface 12a as the contact surface and the upper surface 12b as the second contact surface parallel to the moving direction. The vertical surface 4a has a vertical surface 4a that can face the vertical surface 12a, and a downward surface 4b that can face the top surface 12b. An inclined surface 4c that is inclined to a slightly higher position is provided. For example, when the top plate 2 is slid forward, the latch member 41 moves over the upper surface 12b of the intermediate horizontal member 12 while performing the balance operation around the support shaft m along the inclined surface 4c. 12 (a), the latch members 41, 42, and 43 return to the normal posture through the reverse balance operation, so that the upright surface 4a and the downward surface 4b of the latch member 41 are connected to the intermediate horizontal member 12. It is made to contact | abut or adjoin to the standing surface 12a and the upper surface 12b. Then, when receiving a moving force in the direction in which the top plate 2 is pushed in, the latch member 41 moves in a direction in which the contact force between the rising surfaces 4a and 12a and between the downward surface 4b and the upper surface 12b increases. The intermediate horizontal member 12 is stretched so as to hold the latched state of the top plate 2 at the front slide position 2F.

  Further, the latch release lever 45 described later is operated from this position to bring the latch members 41, 42, 43 into a horizontal posture that does not interfere with the intermediate horizontal member 12 as shown in FIG. When the sliding movement is performed backward, the latch members 41, 42, and 43 return to the normal posture through the balance operation at the position where the inclined surface 4c of the latch member 41 gets over the upper surface 12b of the intermediate horizontal member 12, and the sliding operation continues. As shown in FIG. 13, the rising surface 4 a and the downward surface 4 b of the latch member 42 are brought into contact with or close to the rising surface 12 a and the upper surface 12 b of the intermediate horizontal member 12. Therefore, even if it receives a moving force in the direction in which the top plate 2 is continuously pushed after that, the latch member 43 remains in the direction in which the contact force between the rising surface 4a and the rising surface 12a and between the downward surface 4b and the upper surface 12b increases. In order to stretch against the intermediate horizontal member 12, the latched state of the top plate 2 at the intermediate slide position 2M is maintained.

  Furthermore, after operating the latch release lever 45, which will be described later, from this position to bring the latch member latch members 41, 42, 43 into a horizontal position as shown in FIG. 5B, the top plate 2 is slid backward. Then, at the position where the inclined surface 4c of the latch members 42, 43 gets over the upper surface 12b of the intermediate horizontal member 12, the latch members 41, 42, 43 return to the normal posture of FIG. The rising surface 4a and the downward surface 4b of the latch member 42 are brought into contact with or close to the rising surface 12a and the upper surface 12b of the intermediate horizontal member 12. Therefore, even if it receives a moving force in the direction in which the top plate 2 is pulled forward thereafter, the latch member 42 is increased in the direction in which the contact force between the rising surface 4a and the rising surface 12a and between the downward surface 4b and the upper surface 12b increases. However, the latching state at the rear slide position 2B of the top plate 2 is maintained.

  Incidentally, these latch members 41, 42, 43 are accommodated in a latch housing 40x as shown in FIGS. The latch housing 40x is a thin plate disposed in a gap of about 10 mm existing between the leg structure 1 and the top plate 2, and has through holes 40a, 40b, and 40c at a plurality of locations. The latch members 41, 42, 43 projecting from the thickness only when the top plate 2 is locked to the horizontal member 12 within the thickness so as to be accommodated in the through holes 40a, 40b, 40c, A transmission member 44 that transmits a lever operating force of the latch release lever 45 described below to the latch member is incorporated. A part of the through hole 40c is a bottomed groove. The latch release lever 45 is disposed at a position protruding from the latch housing 40x so as not to interfere with a peripheral portion (particularly, a substrate 40y described later).

  The latch release lever 45 is attached to the lower surface of the front edge portion of the top plate 2 so as to be rotatable about the vertical axis n. Even if any of the operation edges 45a and 45b is operated, the latch member is provided via the transmission member 44. 41, 42, and 43 are rotated so that the locked state with the horizontal member 12 can be released. The transmission member 44 includes a rod 44a that moves back and forth in the depth direction as the latch release lever 45 is rotated, and an operating body that scoops the latch members 41 and 43 around the support shaft m when the rod 44a moves rearward. 44b, and a spring 44c that biases the rod 44a forward and offsets them to the normal position together with the latch release lever 45. 15 (a) → (b), when the actuating body 44b moves rearward, the latch members 41 and 43 are supported by sinking into the tapered force receiving portions 41a and 43a provided integrally with the latch members 41 and 43. A state of scooping up around the axis m is shown. The latch member 42 is attached around the support shaft m in association with a position where the tip 42 b is pushed down by the tip 43 b of the latch member 43, and is configured to operate synchronously with the latch member 43.

  Next, the engagement structures 51 and 52 that restrict the vertical movement of the front edge side of the top plate 2 will be described. As shown in FIGS. 6 to 8, the first movable bracket 21 attached to the support shaft of the front movable roller 20 has a first engagement portion 51 a that projects L-shaped forward, and the top plate 2. The board 40y attached to the lower surface of the front edge side is provided with a second engaging portion 52a having an L-shaped cross section projecting rearward, and the side frame member 14 has a front portion of the top plate 2 in front. Using the housing 23h of the fixed roller 23, the notched first engaged portion 51b is located at the position where the first engaging portion 51a arrives at the slide position 2F (see FIG. 7), and the rear of the top plate 2 Similarly, a slit-like second engaged portion 52b is provided by using the housing 23h of the fixed roller 23 at a position where the second engaging portion 52a arrives at the slide position 2B (see FIG. 8). Then, when the top plate 2 is moved from the rear slide position 2B to the front slide position 2F, the first engaging portion 51a provided on the top plate 2 side as shown in FIG. The engagement structure 51 that restricts the upward movement of the front edge of the top plate 2 is configured by engaging with the first engaged portion 51b provided on the top plate 2, and the top plate 2 is moved from the front slide position 2F to the rear slide position 2B. When moved, the second engaging portion 52a provided on the top plate 2 side is engaged with the second engaged portion 52b provided on the front edge portion of the leg structure 1 as shown in FIG. An engagement structure 52 that restricts vertical movement of the front edge side of the plate 2 is configured. Needless to say, the first engaged portion 51b may be slit-shaped so as to restrict the vertical movement of the front edge side of the top plate 2 when the first engaging portion 51a is engaged.

  Furthermore, in addition to the function of restricting the vertical movement of the top plate 2 described above, the engaging structure 52 including the second engaging portion 52a and the second engaged portion 52b includes the front leg 13a constituting the leg structure 1. It also has a function of steadying the width of the top board.

  That is, as shown in detail in FIGS. 22 and 23, the peripheral shape of the second engaged portion 52b in this embodiment, that is, the upper end portion 23hb of the housing 23h is plate-shaped, and the base end portion of the housing 23h It has a planar shape that is wider than 23 ha in the width direction of the top plate 2 and has a thickness dimension that fits in the gap D between the leg structure 1 and the top plate 2. The upper end 23hb of the housing 23h is screwed to the frame member F1 at one end side h21 protruding onto the frame member F1 of the side frame member 14 and screwed through the screw insertion hole 23h0 provided at that portion. It protrudes from the center of the top plate 2 rather than the base end 23ha. In addition, a substantially rectangular recess such as a slit is provided in the plate-like upper end 23hb of the housing 23h thus taken out above the upper end of the leg structure 1, and this recess is second engaged. The portion 52b is used. On the other hand, the peripheral shape of the second engaging portion 52a, that is, the shape of the substrate 40y formed partly is a plate-like shape, attached to the lower surface of the top plate 2, and the top plate 2 is normally used. 22 (a) to 22 (c) at the position 2B, it has a planar shape that is located above the front leg 13a and is wider than the front leg 13a toward the center of the top board, and the leg structure 1 and the top board 2 The thickness dimension fits in the gap D. Then, a substantially rectangular protrusion is provided on the plate-like substrate 40y suspended on the lower surface of the top plate 2 as described above, and this protrusion serves as a second engaging portion 52a. The second engaging portion 52a has a width dimension and a vertical dimension that can be inserted relatively tightly into the second engaged portion 52b. The engagement portion 52a and the engaged portion 52b are engaged. The width direction engagement dimension Lx of the combined structure 52 is set to be longer than the width dimension Ly of the front leg 13 a located at the front end of the leg structure 1.

  That is, when the top plate 2 moves rearward to the normal use position 2 </ b> B by the engagement structure 52, the second engagement portion 52 a located on the front end side of the top plate 2 is at the front end portion of the leg structure 1. The top plate 2 is engaged with the second engaged portion 52b, so that the top plate 2 is integrated with the leg structure 1 including the frame member F1 and the front leg 13a via the base plate 40y and the housing 23h. While the frame member F1 is twisted, the operation of tilting the lower end portion in the width direction with the upper end portion serving as a fulcrum (the operation indicated by the arrow Z in FIG. 22C) is suppressed.

  Furthermore, the regulation parts 61 and 62 which regulate the vertical movement of the rear edge side of the top plate 2 will be described. As shown in FIGS. 5 and 10, the restricting portion 62 has the horizontal groove f of the rear horizontal member 11 located on the lower surface in the vicinity of the rear edge portion of the top plate 2 at the rear slide position 2 </ b> B and continuously opening forward. In view of this, a roller 25 is attached to the lower surface on the rear edge side of the top plate 2 via a horizontal shaft, and the roller 25 is engaged with the horizontal groove f as the top plate 2 moves. Further, as shown in FIGS. 5 and 9, the restricting portion 61 is continuously rearward with the horizontal groove f of the intermediate horizontal member 12 positioned on the lower surface near the rear edge of the top plate 2 at the front slide position 2F. In view of the opening, a roller 26 similar to the roller 25 is attached to the lower surface of the rear edge portion side of the top plate 2 via a horizontal shaft, and this roller 26 is engaged with the horizontal groove f.

  On the other hand, as shown in FIGS. 4, 5 and 9, etc., the center drawer 3 includes a pulling portion 31, a bottom plate 32, left and right side plates 33, and a back plate 34, and the width dimension is the same as the width dimension of the top plate. It is a flat box shape having substantially the same vertical dimension set to about 30 mm, and has a flat box shape positioned between the front half portions of the left and right leg elements 1a when the depth dimension is pushed in. The depth of the center drawer 3 constituting the furniture with the top plate is set to about half of the depth size of the top plate 2, and is positioned behind the center drawer 3 between the rear half portions of the left and right leg elements 1a. The fixed tray 7 is provided. The center drawer 3 is attached to the horizontal groove f of the side frame member 14 in front of the first bracket 23h attached to the horizontal groove f continuously opening to the side of the side frame member 14 and the intermediate horizontal member 12. A suspension rail 30a, which is a rail member, is attached over the second bracket 30 so as not to interfere with the first movable bracket 21, and a side plate 33 is supported on the suspension rail 30a so as to be slidable back and forth.

  In the present embodiment, the first bracket 23h is common to the housing 23h of the fixed roller 23, and has both functions.

  On the other hand, the fixed tray 7 includes a front plate 71, a bottom plate 72, and a rear plate 73. The front plate 71 and the rear plate 73 are used as the intermediate horizontal member 12 and the rear horizontal member 11, respectively, using a horizontal groove f. The top plate 2 is attached so as not to interfere with the sliding operation. That is, the top plate 2 is slidable between a front slide position 2F in FIG. 2 that opens the fixed tray 7 upward and a rear slide position 2B in FIG. 3 is between the drawer position 3F in FIG. 3 that protrudes forward with respect to the top plate 2 that closes the fixed tray 7 and opens upward, and the push-in position 3B in FIG. It is possible to move the slide. In FIG. 6, reference numeral 70 denotes a mounting bracket for the fixed tray 7, which is attached to the horizontal groove f of the side frame member 14 behind the intermediate horizontal member 12.

  As described above, the furniture with a top plate is characterized in that the top plate 2 and the center drawer 3 are extremely thin, and the appearance is greatly different from the conventional furniture with a top plate.

  The movable roller 20 is inserted into the frame member F1 with its end opened before the leg structure 1 is assembled, or a notch that can be closed with a cap or the like is provided at an appropriate position and inserted from there. do it. Further, it is convenient to use a nut member 8 as a stator as shown in FIG. 18 for attaching the brackets 23h, 30, 70, etc. to the rail groove f. The nut member 8 has a width h smaller than the groove width fx of the frame member F1 and has a length h substantially equal to the internal dimension FX in the vertical direction of the frame member F1. The nut member 8 has a horizontal groove f. An eccentric weight structure that naturally rotates approximately 90 ° after being inserted into the inside is formed. A pair of convex portions 80 formed on the brackets 23h, 30, and 70 are inserted into the nut member 8 so as to hold both edges 8a of the nut member 8, and the brackets 23h, 30, and 70 are passed through in this state. By tightening the screw 81 in the screw hole 8b provided in the nut member 8, the brackets 23h, 30, and 70 can be fixed to the frame member F1 using the horizontal groove f.

  Further, in this embodiment, the top plate 2 and the center drawer 3 are supported so as to be slidable independently of the leg structure 1, and the top plate 2 and the center drawer 3 are simultaneously applied to the leg structure 1. A lock mechanism 9 for locking is provided.

  As shown in FIGS. 4, 5, and 19 to 21, the lock mechanism 9 includes a lock rod 91 that is provided on the center drawer 3 and can project and retract in a direction perpendicular to the slide direction, the top plate 2, The leg structure 1 is provided with insertion windows 92a and 93a provided using brackets 92 and 93, and the top plate 2 and the center drawer 3 are inserted by inserting / removing the lock rod 91 into / from the insertion windows 92a and 93a. Can be locked and unlocked simultaneously with respect to the leg structure 1.

  More specifically, the lock rod 91 of the lock mechanism 9 is electromagnetically driven by an actuator 94, reads a user identifier from a recording medium such as an ID card via a reader 95, and the microcomputer unit 96 Only when the authentication is successful, the operation of the lock mechanism 9 is permitted. The microcomputer unit 96 is a normal unit including a CPU 96a, an internal storage device 96b, an external storage device 96c, and an input / output device 96d. The internal storage device 96b and the like store an authentication program, and can be locked and unlocked. It functions as a later-described user identifier registration unit 9b for registering a user identifier given to an authorized person. Then, the CPU 96a sequentially reads and executes the program, thereby registering the locking / unlocking portion 9a that gives an operation command to the actuator 94 that drives the lock rod 91, and the user identifier given to those who have the authority to lock and unlock. The user identifier registration unit 9b, the reading unit 9c that reads the user identifier from the identifier recording medium that proves that the user has the authority to lock and unlock, and the read user identifier is registered in the user identifier registration unit 9b. A determination unit 9d that determines whether or not a certain user identifier matches, and an operation input received by the operation reception unit 9e when the determination unit 9d determines that it matches, from the unlocking unit 9a An operation command is output.

  Although the furniture with a top plate of this embodiment consists of the structure demonstrated above, especially in view of the top plate 2 being a structure which slide-moves in the front-back direction with respect to the leg structure 1, the top plate 2 22 moves rearward to the normal use position 2B, the front end side of the top plate 2 is engaged with the front end portion of the leg structure 1, and the front end portion of the leg structure 1 has the upper end portion as a fulcrum. The function of suppressing the tilting operation in the width direction (Z direction) shown in (c) is exhibited.

  In such a case, as long as the top plate 2 is engaged with the leg structure 1, an effect equivalent to or equivalent to that obtained by fixing the top plate 2 to the leg structure 1 can be obtained. Even if a structure that slides 2 is adopted, the phenomenon that the front end of the leg structure 1 opens in a C-shape in front view or is distorted into a parallel link at the normal use position 2B is effectively prevented. It is possible to ensure a proper use state.

  Further, the engaged portion 52b shown in FIGS. 22 and 23 is provided above the upper end portion of the leg structure 1, and the engaging portion 52a provided on the lower surface of the top plate 2 is provided on the engaged portion 52b. Since it is made to engage, the engaging part 52a and the to-be-engaged part 52b can be formed without interfering with the leg structure 1, and the engaging structure 52 suitable for required strength can be easily realized. Is possible.

  Further, the shape around the engaged portion 52b, that is, the shape of the housing 23h forms a plate shape that fits in the gap D between the leg structure 1 and the top plate 2, and the shape of the substrate 40y that is the shape around the engaging portion 52a. Is attached to the lower surface on the front end side of the top plate 2 and has a plate shape that fits in the gap D between the leg structure 1 and the top plate 2, even if the top plate 2 is a slide top plate, it is as if the front legs 13a A plate is provided at the upper end, and the appearance and mounting strength equivalent to the plate fixed to the lower surface of the top plate 2 can be realized.

  Moreover, since the engagement dimension Lx of the engaging part 52a and the to-be-engaged part 52b along the width direction of the top plate 2 is set longer than, for example, the width dimension Ly of the leg structure 1, etc. Even when the front leg 13 of the structure 1 is slightly tilted, a deterring force due to the engagement structure works, and even if the slide top plate 2 and the center drawer 3 are employed, a loosely used state can be realized.

  Furthermore, the thing of this embodiment comprises the engaging part 52a of the top plate 2 from the protrusion which protrudes in the sliding direction of the said top plate 2, and the to-be-engaged part 52b of the leg structure 1 receives the said protrusion. Since it is constituted by a substantially rectangular recess, it is possible to effectively realize an engagement structure that is simple and exhibits a required tilt suppression effect.

  Therefore, as described above, the leg structure 1 is extremely useful when applied to furniture with a top plate including the pillar-type legs 13a and 13b that are independent in the front, rear, left and right.
