technical field

The present invention relates to the table used in working space such as office or reception room; The adjustment mechanism in the furniture used in the work space such as office or reception room and the table with this adjustment mechanism; The article installation structure that is installed on the installation plane on the structural parts such as appliances.

This application is based on the patent application No. 2007-287881 filed in Japan on November 5, 2007, the patent application No. 2007-287882 filed in Japan on November 5, 2007, and the patent filed in Japan on January 22, 2008 Priority is claimed based on application No. 2008-011563, the contents of which are incorporated herein.

Background technique

In the desks used in working spaces such as offices or reception rooms, the desktop is fixed on multiple supports, and the rigidity of the desktop is used to support the self-weight and load weight of the desktop so that the desktop does not bend (for example, refer to Patent Document 1 ). In addition, by erecting the crossbeam on a plurality of supports and fixing the tabletop on the crossbeam, the rigidity of the crossbeam or the rigidity of the crossbeam and the tabletop is used to support the self-weight and load weight of the tabletop so that the tabletop does not bend ( For example, refer to Patent Document 2).

In recent years, in the above-mentioned desks, in addition to securing the necessary rigidity, it is desired that the number of support members be installed as small as possible and that the size of the components be as small as possible in terms of usability and design performance.

In addition, furniture such as desks used in working spaces such as offices and reception rooms needs to be installed so that they can be adjusted to be horizontal regardless of the state of the floor surface, and it is desirable to have an adjustment mechanism that can adjust height and levelness.

The adjustment mechanism is composed of a base directly abutting against the floor, an adjustment bolt protruding from the base to support the furniture body, and an adjustment nut supporting the furniture body relative to the adjustment bolt to adjust the height. The furniture has plural sets of these adjustment mechanisms to support the furniture main body (for example, refer to Patent Documents 3 to 5). By adjusting the position of the adjustment nut relative to the adjustment bolt of the adjustment mechanism, the height and the levelness of the surface supporting the main body of the furniture can be adjusted. In addition, in the adjustment mechanism described above, the adjustment bolt is attached to the base in a swingable state, whereby the angle of the base can be adjusted with respect to the adjustment bolt. Therefore, even if the floor surface is inclined, the adjustment bolt can be arranged in the vertical direction, and the base can be tilted so that the entire bottom surface of the base can abut against the floor surface.

On the installation plane perpendicular to the floor surface formed on furniture and other daily utensils, the well-known method of installing the article is: by making the installation screw pass through the through hole provided on the article, and threadedly cooperate with the screw hole provided on the installation plane , to fix items with threads; and to glue the installation plane and the installation surface of the item, etc. As a result, objects can be mounted on the mounting plane in a simple manner. However, when you want to repeatedly attach and detach an item, or when you want to install an item whose installation position can be changed in the left-right direction (horizontal direction) of the installation plane, etc., it is necessary to perform peeling and bonding work, or It is necessary to provide a plurality of processing positions for mounting in the left and right directions. Therefore, the aesthetic appearance of the installation plane is impaired.

Therefore, a method has been proposed in which, by forming locking grooves facing the left and right directions on the mounting plane, locking pieces provided on the article are locked on the locking grooves, and the article (cover support member) ) is installed so that the installation position can be changed in the left-right direction of the installation plane (item installation plate) (for example, refer to Patent Document 6).

However, since a table used in a working space such as an office or a reception room is used by many persons such as a meeting at the same time, it is necessary to use a tabletop that is long and thin in one direction. However, if a slender tabletop is used and the number of support members is to be reduced as much as possible, as in Patent Document 1, the rigidity of the tabletop itself is used to support the dead weight and the load weight, which will make the tabletop very thick and heavy. . Therefore, the overall weight of the table is increased, and the assembly performance when assembling the table top board is lowered.

In the table of Patent Document 2, although the thickness of the table top can be made as small as possible, and the overall weight is lighter than that of the table of Patent Document 1, the weight of the beam increases with the increase of the distance between the supports. Therefore, it is difficult to lift the beam and set it at a prescribed fixed position on the support, and the assembly performance of the beam is degraded.

In addition, according to the adjustment mechanisms of Patent Documents 3 to 5, the floor surface on which the furniture is installed supports the weight of the furniture within the range of the bases on which each adjustment mechanism is installed, and the floor surface on which the furniture is installed generally bears point loads. Therefore, when the weight of the furniture is heavy, a dent or the like occurs in the installation range of the adjustment mechanism, and there is a problem that the floor surface is damaged. In addition, when the weight of the furniture is heavy, there is also a problem of damaging the adjusting bolts and adjusting nuts that directly support the main body of the furniture in the adjusting mechanism. Although it is also possible to solve the above problem by increasing the number of locations where the adjustment mechanism is installed and reducing the load carried by each adjustment mechanism, it is necessary to adjust all the adjustment mechanisms when adjusting the height and level, which makes the adjustment troublesome.

In addition, since the article mounting structure of Patent Document 6 does not have a positioning member in the left-right direction (horizontal direction) when an article (cover support member) is mounted on the locking groove, it is difficult to accurately align the position.

Contents of the invention

In view of the above circumstances, the present invention provides a table that can easily mount the beams to the supports even if the interval between the supports becomes large and the weight of the beams increases, and when assembled, the beams can be reliably supported on the supports above, it becomes a fixed state.

Furthermore, in view of the above circumstances, the present invention provides an adjustment mechanism and a table having the adjustment mechanism, which can transfer the weight of the furniture main body to the floor surface without damaging the floor surface, and can easily adjust the height and levelness.

In addition, in view of the above circumstances, the present invention provides an article installation structure capable of reliably installing an article at a desired position in the locking groove.

In order to solve the above-mentioned problems, the present invention proposes the following means.

The table of the first invention of the present invention includes: a desktop board, which is basically plate-shaped; a pair of beams arranged side by side on the lower surface of the table board to support and fix the table board; There are multiple sets in the direction, supporting and fixing the pair of beams, the support has a pair of first bearing surfaces and a pair of second bearing surfaces, the pair of first bearing surfaces are basically horizontal, and are arranged on the The upper part of the support member, the pair of second bearing surfaces extend from the first bearing surface and are arranged obliquely along the width direction of the beam, the beam has a desktop board support surface, a first bottom surface and a second bottom surface, The desktop board support surface fixes the desktop board, the first bottom surface abuts and is supported on the first bearing surface at least in the range supported by the support member in the length direction, and the first bottom surface The two bottom surfaces are extended from the first bottom surface and arranged obliquely, contacting and supporting the second bearing surface.

According to the table of the first invention, by abutting and supporting the first bottom surface of the pair of beams on the first bearing surface which is substantially a horizontal plane, and abutting and supporting the second bottom surface on the second bearing surface which is an inclined surface, Therefore, a pair of beams are reliably supported and fixed on the supporting member. By supporting and fixing the tabletop on each tabletop support surface of a pair of beams supported by the support members, the thickness of the tabletop can be made as small as possible even if the interval between the support members is increased, and the tabletop can be reliably supported by the beams plate so that it does not bend.

Wherein, when assembling the support member, the beam and the desktop board, the following steps are performed. That is, a plurality of supports are arranged side by side at predetermined intervals. Then, lift the crossbeam arranged near the support along the direction in which the support is arranged, and move to the top of the support. Then, in the state of lifting the cross beam, when the relative positions of the cross beam and the supporting member are basically aligned, the operator lowers the cross beam. Wherein, the supporting member has a second bearing surface as an inclined surface, and the beam has a second bottom surface corresponding to the second bearing surface. Therefore, even if the position of the crossbeam in the width direction deviates slightly relative to the support, the crossbeam abutting against the second bearing surface of the support with the second bottom surface will descend along the inclined surface of the second bearing surface by its own weight. The beam can thus be guided to the defined fixed position on the upper part of the support without fine adjustments by the operator. When the crossbeam is guided to a predetermined fixed position, its own first bottom surface abuts against the substantially horizontal first bearing surface of the support. As a result, the beam is correctly positioned at a prescribed fixed position on the upper part of the support, and the beam is reliably supported by the support. After the crossbeam is reliably fixed on the support member, the support member, the crossbeam and the tabletop board are assembled into one body by placing and fixing the tabletop board on the tabletop support surface of the crossbeam.

In the table of the first invention, it is preferred that: the first load-bearing surface is arranged continuously from the upper end of the second load-bearing surface, and the support member also has a pair of third load-bearing surfaces, and the third load-bearing surface is basically being horizontal and extending from the lower end of the second bearing surface, the beam has a third bottom surface, and the third bottom surface is abutted against and supported on the third bearing surface.

Therefore, the beam can be more stably supported by the support. Furthermore, when assembling the crossbeam on the support, the crossbeam is guided to descend along the second bearing surface which is an inclined surface, and in the fixed position, the first bottom surface abuts against the first substantially horizontal plane bearing surface, and the second The three bottom surfaces are also abutted against another third bearing surface which is basically a horizontal plane. Thereby, positioning can be performed more reliably.

In this case, when attaching the pair of beams to the support, first, each beam is lifted from both outer sides of the support and moved toward the inside in the width direction. Then, each crossbeam is placed on the second carrying surface, and each crossbeam is directly descended along the widthwise inner side of the inclined surface of the second carrying surface, thereby guiding it to a prescribed fixed position. Therefore, it is easier to mount the beam on the support.

In the desk according to the first invention, preferably, the beam has an inclined surface, the inclined surface includes the second bottom surface, and extends along the length direction of the beam.

In this case, at the upper portion of the beam, the table top board can be reliably supported over a wider range in the width direction by the table top board support surface. Furthermore, even if a seated user puts their feet under the tabletop, the beam does not become an obstacle.

As shown in Figure 3, a pair of beams 20 are respectively extended so that: the end edge 20a on the outside of the width direction Y and the side plate 30a of the support member 30 generally form a plane; and as shown in Figures 1 and 2, the length direction The end 20b on the X protrudes outward from the supporting member 30 so as to support a pair of beams 20 on the supporting member 30 . As shown in FIG. 4 , the beam 20 continuously forms a desktop support surface 21 and an inclined surface 22 in the length direction X, the desktop support surface 21 is used as the upper surface for carrying the desktop 10, and the inclined surface 22 is used as the lower surface. It inclines from the outer side to the inner side in the width direction Y. Thereby, the cross-section of the beam 20 is formed in a substantially triangular shape. Moreover, the end part 20b in the longitudinal direction X of the beam 20 is made to incline toward the inside of the longitudinal direction X from the table board supporting surface 21, and is covered with the end cover 20c. The crossbeam 20 is made hollow inside to control the weight and improve the rigidity, and a reinforcing plate 20d is arranged in the center of the crossbeam 20 along the vertical direction Z to further improve the rigidity. As shown in FIGS. 2 and 4, in this embodiment, two beam members 20e are connected in the longitudinal direction X by using a first connecting member 20f with a substantially C-shaped cross section and a second connecting member 20g with a V-shaped cross-section. Instead, each beam 20 is configured to make the span between the supports 30 longer.

Wherein, the second bottom surface 24 is a part of the inclined surface 22 . And, by making the first bottom surface 23 of each beam 20 abut on the first load-bearing surfaces 34A, 34B, the second bottom surface 24 abut on the second load-bearing surfaces 35A, 35B, and the third bottom surface 25 abut against the third load-bearing surfaces. Each beam 20 is supported on supports 30 on the faces 36A, 36B.

A locked end 26 protruding inward in the width direction Y is provided at a lower portion of the beam 20 . The beam 20 is locked in the width direction Y by making the locked end 26 of the beam 20 abut against the locking piece 37 of the support member 30 .

In addition, screw holes 28 are respectively formed on the first bottom surface 23 and the second bottom surface 24 of the beam 20 .

On the other hand, on the first bearing surface 34A, 34B and the second bearing surface 35A, 35B of the support 30 , through holes 38 corresponding to the respective screw holes 28 and communicating with the inside of the box member 31 of the support 30 are formed. By passing the beam fixing bolt 40 from the inside of the box member 31 of the support 30 through the through hole 38, and screwing with the screw hole 28, each beam 20 is fixedly installed with the first bearing surface 34A, 34B and the second bearing surface 35A, 35B. on the support 30 .

As shown in FIG. 1 , the tabletop 10 is composed of a plate member 11 divided into two in the longitudinal direction X, two in the width direction Y, and four as a whole. As shown in FIG. 3 , each plate member 11 is supported by each beam 20 by bringing the lower surface of each plate member 11 constituting the table top 10 into contact with each table top support surface 21 . As shown in FIG. 4 , screw holes 12 are formed at a plurality of locations in the longitudinal direction X on the lower surface of each plate member 11 . On the other hand, at a plurality of positions in the longitudinal direction X of the beam 20 , through holes 29 communicating in the vertical direction Z are formed, and the positions of the through holes 29 coincide with the screw holes 12 . By passing the table board fixing bolts 41 through the through holes 29 from the underside, and screwing with the screw holes 12 of the board members 11, the board members 11 constituting the table board 10 are fixedly installed on the beam 20.

Among them, the first locked piece 13 and the second locked piece 14 are attached to the lower surface of each plate member 11 . The first locked piece 13 and the second locked piece 14 protrude inward in the width direction Y, respectively. A first locking groove 21a and a second locking groove 21b extending in the longitudinal direction X are formed on the desktop support surface 21 of each beam 20, so that the first locking groove 21a and the second locking groove 21b are respectively connected to The first locked piece 13 corresponds to the second locked piece 14 . The first locking groove 21a and the second locking groove 21b are respectively provided with locking edge portions 21c, 21d protruding from the inner side edge in the width direction Y to the outer side in the width direction Y. In the state where each plate member 11 constituting the desktop board 10 is supported on the beam 20, by inserting the first locked piece 13 and the second locked piece 14 into the first locking groove 21a and the second locking groove 21a respectively, In the groove 21b, the first to-be-locked piece 13 and the second to-be-locked piece 14 are engaged with the respective locking edge portions 21c and 21d. Accordingly, each plate member 11 is securely fixed to the beam 20 together with the fixing by the table top fixing bolts 41 .

Notches 11 a are respectively formed at positions inside the plate member 11 in the width direction Y. In the combined state of fixing each plate member 11 on the beam 20, a wiring communication hole 10a is formed on the table top 10 by using a cutout 11a. The wiring communication hole 10a communicates up and down at the center in the width direction Y, and It extends in the longitudinal direction X. Normally, the wiring communication hole 10a is covered with a tabletop cover 10b. On the side surfaces 20i of the pair of lateral beams 20 facing each other, a cover attachment groove 20h extending in the longitudinal direction X is formed. The upwardly extending supporting member 15 is engaged with the lid attachment groove 20h. The desktop cover 10b is supported by the support member 15, and covers the wiring communication hole 10a. The desktop board cover 10b can be assembled and disassembled with respect to the support member 15. By removing the desktop board cover 10b, the wiring of the electrical equipment used on the desktop board 10 can be arranged on a pair of beams 20 through the wiring communication hole 10a. The threading space 43 between is laid out. The bottom of the threading space 43 is covered with a bottom plate 43a engaged between the pair of beams 20, and wiring can be arranged on the bottom plate 43a. The wiring of the electrical equipment laid in the wiring space 43 can be connected to the power supply etc. on the floor surface F further through the communication groove 30c.

In the table 1 as described above, the table top 10 is supported and fixed on the table top supporting surfaces 21 of a pair of beams 20 supported by the support members 30 . Thereby, even if the distance between the supports 30 is increased, the thickness of the tabletop 10 can be reduced as much as possible, and the tabletop 10 can be reliably supported by the beams 20 without bending the tabletop 10 . In addition, the crossbeam 20 has an inclined surface 22 , which can ensure that the size of the desktop support surface 21 supporting the desktop 10 in the width direction Y is sufficiently large. In addition, the beam 20 is arranged such that its end edge 20 a substantially coincides with the side portion of the support member 30 . Therefore, the tabletop 10 can be reliably supported over a wider range in the width direction Y, so that the bending of the tabletop 10 in the width direction Y can be more effectively prevented. On the other hand, since the inclined surface 22 of each beam 20 is continuously formed along the longitudinal direction X outside the width direction Y, even if the user sits in the longitudinal direction X and places his feet under the table top 10, the beams 20 will not will become an obstacle.

Likewise, the beam 20 is extended to protrude from the support member 30 to the outside in the longitudinal direction X, and its end 20b is inclined. Therefore, it is also possible to reliably support the table top 10 in a wider range in the length direction X, so that the bending of the table top 10 in the length direction X can be effectively prevented, and even if the user sits in the width direction Y and puts The feet are placed under the desktop board 10, and the beam 20 and the support member 30 will not become obstacles.

The beam 20 supporting the desktop 10 is reliably supported by the second bearing surface 35A, 35B which is an inclined surface, and the first bearing surface 34A, 34B and the third bearing surface 36A, 36B which are substantially horizontal planes. Especially in the present embodiment, since there are first bearing surfaces 34A, 34B and third bearing surfaces 36A, which are substantially horizontal planes, on both sides of the upper and lower ends of the inclined surfaces of the second bearing surfaces 35A, 35B as inclined surfaces respectively. , 36B, so the beam 20 can be supported more stably. Moreover, the 2nd receiving surface 35A, 35B respectively corresponding to a pair of beam 20 inclines from the outer side to the inner side in the width direction Y, and is set so that the direction of inclination may differ from each other. Therefore, by supporting the beam 20 with the second bearing surfaces 35A, 35B which are inclined surfaces, although a horizontal force acts on the support 30 , since the horizontal forces acting on the support 30 are canceled out by the respective beams 20 , so the beam 20 can be stably supported by the support member 30 . By using beam fixing bolts 40 as fixing members to fix the beam 20 on the two different bearing surfaces of the first bearing surface 34A, 34B and the second bearing surface 35A, 35B, the beam 20 can be more firmly fixed to the supporting member. 30 on.

As shown in FIGS. 5 and 6 , in the present embodiment, the adjustment mechanisms 60 are provided in pairs in the width direction Y in correspondence with the respective box members 31 constituting the support 30 . Each adjustment mechanism 60 includes: a support plate 61 configured under the support member 30 and placed on the floor surface F; an adjustment bolt 62 configured to protrude from the support plate 61 to the support member 30; and an adjustment nut 63 arranged on the support member 30 On the bottom plate 30d of the member 30, it is screwed with the adjusting bolt 62. In addition, each adjustment mechanism 60 includes: a fixing bolt 64 protruding downward from the bottom plate 30 d ; a fixing nut 65 arranged on the bottom plate 30 d of the support member 30 and threadedly engaged with the fixing bolt 64 .

As shown in FIG. 7 , the support plate 61 is formed in a wide width corresponding to the box member 31 , and the notch 61 a corresponds to the communication groove 30 c of the support 30 . As shown in FIG. 5 , in the present embodiment, two adjustment bolts 62 are provided in each adjustment mechanism 60 and are arranged side by side on a straight line along the width direction Y. As shown in FIG. Each adjusting bolt 62 has: a screw main body 62a formed with a male thread; a diameter contraction portion 62b arranged at the bottom end of the screw body 62a and shrinking in diameter from the screw body 62a; an engaged portion 62c formed at the bottom of the diameter contraction portion 62b end, expanding in diameter into a flange shape. In addition, an operation recess 62d into which a hexagon wrench can be inserted and engaged is formed at the front end.

Among them, the locking plate 66 is attached to the upper surface of the support plate 61 with attachment bolts 66 a. The locking plate 66 is formed of a substantially rectangular thin-walled member. At the mounting position of the adjusting bolt 62 on the locking plate 66, an engaging portion 67 having a concave lower surface and a convex upper surface is formed by press forming. Thus, a space 67 a is formed between the supporting plate 61 and the engaging portion 67 of the locking plate 66 . A through hole 67 b having a diameter smaller than the outer diameter of the screw body 62 a of the adjustment bolt 62 is formed in the engaging portion 67 and communicates from the upper surface side of the engaging portion 67 to the lower surface side. The reduced-diameter portion 62b of the adjustment bolt 62 passes through the through hole 67b. At this time, the engaged portion 62c having an outer diameter larger than the diameter of the through hole 67b is arranged inside the space 67a. By abutting the bottom end of the screw main body 62a against the upper surface of the locking plate 66, the adjusting bolt 62 is supported on the support plate 61, so that the front end side can tilt and move in a swinging manner, and can rotate around the axis. .

The adjustment nut 63 is connected to the lower surface of the bottom plate 30d of the support member 30 by welding to form an adjustment screw hole 63a threadedly engaged with the adjustment bolt 62 . On the bottom plate 30d of the support member 30, at the position connected to the adjustment nut 63, a through hole 30e communicating with the inside of the support member 30 is formed, and the front end of the adjustment bolt 62 threaded with the adjustment screw hole 63a extends from the through hole 30e. out.

Similarly, the fixing nut 65 is also connected to the lower surface of the bottom plate 30d of the support member 30 by welding to form a fixing screw hole 65a threadedly engaged with the fixing bolt 64 . On the bottom plate 30d of the support member 30, at the position where the fixing nut 65 is connected, a through hole 30f communicating with the inside of the support member 30 is formed. The fixing bolt 64 is screwed into the fixing screw hole 65 a, so that the head 64 a of the fixing bolt 64 is located inside the support member 30 , and the end 64 b is located between the support member 30 and the support plate 41 . Therefore, by applying torque to the head portion 64a located inside the support 30 with a wrench or the like, the end portion 64b can be moved from the support 30 side to the support plate 61 side to abut against the support plate 61 . In this embodiment, there are two sets of sets of fixing bolts 64 and fixing nuts 65 in each adjustment mechanism 60 , arranged in the longitudinal direction X, and intersecting the width direction Y which is the direction in which the adjustment bolts 62 are arranged.

The adjustment mechanism 60 also includes: a generally frame-shaped first sleeve portion 68, which is arranged to protrude from the support plate 61 to the support member 30; a generally frame-shaped second sleeve portion 69, which is arranged to protrude from the bottom plate 30d of the support member 30 protrudes toward the support plate 61. The first sleeve portion 68 is provided with a gap formed between it and the bottom plate 30 d of the support 30 , and surrounds the adjustment bolt 62 and the fixing bolt 64 around the locking plate 66 . The second sleeve portion 69 is configured to extend from the side of the support member 30 and protrude downward. A gap is formed between the second sleeve portion 69 and the support plate 61 . The second sleeve portion 69 is disposed outside the first sleeve portion 68 to overlap with the first sleeve portion 68 in the longitudinal direction X and the width direction Y, and surrounds the adjusting bolt 62 and the fixing bolt 64 .

Next, the assembly procedure of the table 1 of this embodiment is demonstrated. First, as shown in FIG. 8 , on the floor surface F on which the desk 1 is installed, the supports 30 are arranged side by side at predetermined intervals.

Then, each adjustment mechanism 60 is adjusted with the adjustment bolt 62 . That is, a hexagonal wrench or the like is inserted into the operation recess 62 d of the adjustment bolt 62 from inside the support 30 to rotate the adjustment bolt 62 . Adjusting nuts 63 threadedly engaged with the adjusting bolts 62 are fixed on the support member 30 , and the adjusting bolts 62 are engaged with locking plates 66 fixed on the supporting plate 61 . Thus, by turning the adjusting bolt 62 in different directions, the supporting member 30 can be moved up and down relative to the supporting plate 61 , and the entire supporting member 30 can be moved obliquely along the width direction Y. And, by turning each adjusting bolt 62, the support member 30 is moved up and down, the first bearing surface 34A, 34B and the third bearing surface 36A, 36B of the support member 30 are adjusted to be substantially horizontal, and the opposite pair of support members 30 are roughly equal in height. In this embodiment, since one support member 30 has two adjustment mechanisms 60 , four adjustment bolts 62 need to be adjusted for each support member 30 . In addition, at this stage, the support member 30 is only supported by the adjustment bolt 62, and can move obliquely in the longitudinal direction X. As shown in FIG.

Then, the horizontality of the support member 30 in the longitudinal direction X is made uniform, and the heads 64 a of the two fixing bolts 64 are clamped inside the support member 30 and rotated so that the fixing bolts 64 abut against the support plate 41 . Thereby, the support 30 is supported by the support plate 61 by the fixing bolt 64, and the inclination movement to the longitudinal direction X is restricted. Therefore, regardless of the inclination state of the floor surface F, the table top board 10 is in a substantially horizontal state.

Then, as shown in FIGS. 9 and 10 , the beam 20 is assembled near the supports 30 in the direction in which the supports 30 are arranged. Next, the assembled beam 20 is lifted and moved from the outer side to the inner side in the width direction Y, so that the beam 20 is arranged above the supporting member 30 . In the state where the beam 20 is raised, the beam 20 is lowered after the relative position of the support member 30 is substantially aligned. Wherein, the support member 30 has second bearing surfaces 35A, 35B as inclined surfaces, and the beam 20 has a second bottom surface 24 as an inclined surface corresponding to the second bearing surfaces 35A, 35B. Therefore, even if the position of the beam 20 in the width direction Y is different from that of the support 30, if the second bottom surface 24 of the beam 20 abuts on the second bearing surfaces 35A, 35B of the support 30, the beam 20 will directly move along the bearing surface due to its own weight. The inclined surfaces of the second load-bearing surfaces 35A, 35B are lowered, and the operator who assembles can guide the beam 20 to the specified fixed position on the upper part of the support member 30 without fine-tuning. At this time, because the direction in which the operator lifts the crossbeam 20 to move it and the direction in which the second carrying surfaces 35A, 35B are inclined downward are from the outside to the inside in the width direction Y, they are consistent, so the operator does not change The moving direction of the raised cross beam 20 can guide the cross beam 20 to a prescribed fixed position, and the cross beam 20 can be installed on the supporting member 30 more easily.

When the crossbeam 20 is guided into a predetermined fastening position, the first bottom surface 23 of the crossbeam 20 abuts against the substantially horizontal first support surfaces 34A, 34B of the support part 30 . As a result, the beam 20 is reliably supported on the support 30 in a state where it is accurately positioned at a predetermined fixed position on the upper portion of the support 30 .

Especially in this embodiment, the third bottom surface 25 of the crossbeam 20 also abuts against the substantially horizontal third bearing surfaces 36A, 36B, and the locked end 26 of the crossbeam 20 is supported by the support member 30 in the width direction Y. The locking piece 37 is locked. As a result, the beam 20 can be supported on the support member 30 in a more reliably positioned state.

Then, the side plate 30a of the support member 30 is removed, and the beam fixing bolt 40 passes through the through hole 38 from the inside of the box member 31 of the support member 30, and is threadedly engaged with the screw hole 28 of the beam 20. Thus, the beam 20 is fixed on the support 30 . In the state where the pair of beams 20 are fixed, the pair of beams 20 are respectively engaged with the bottom plate 43a, and the bottom of the threading space 43 is covered with the bottom plate 43a.

Then, as shown in FIGS. 3 and 4 , the desktop board 10 is installed. First, the first locked piece 13 and the second locked piece 14 are respectively attached to the lower surface of each plate member 11 constituting the table top 10 . The plate members 11 are then placed on the beams 20 . At this time, each plate member 11 is arranged in advance slightly outside the predetermined position in the width direction Y. Next, by sliding each plate member 11 from the outside to the inside in the width direction Y, the first locked piece 13 and the second locked piece 14 are buried in the first locking groove 21a and the second locking groove 21a corresponding thereto. The groove 21b is engaged with the locking edge portions 21c and 21d. Thereby, the plate member 11 is reliably positioned in the up-down direction Z and the width direction Y. As shown in FIG. Then the desktop board fixing bolts 41 are passed through the through holes 29 from the lower side of the cross beam 20 , and the table board 10 is fixed on the cross beam 20 by screwing with the screw holes 12 . Thereby, as shown in FIG. 1 and FIG. 2 , the support member 30 , the cross beam 20 and the desktop board 10 are assembled into one body. Finally, the support member 15 is engaged with the cover mounting groove 20h of the beam 20, and the table top cover 10b is attached to the support member 15 to cover the wiring communication hole 10a of the table top 10, thereby completing the assembly.

As described above, in the table 1 of the present embodiment having the support member 30, the beam 20, and the tabletop 10, even if the distance between the support members 30 becomes large and the weight of the beam 20 increases, the beam 20 can be easily attached to the table. on the support 30. In addition, when assembled, the beam 20 can be in a state of being reliably supported and fixed on the supporting member 30 .

In the table 1 of the present embodiment, the adjustment mechanism 60 can easily adjust the height and the levelness only by abutting the fixing bolt 64 after adjusting the adjusting bolt 62 . After the adjustment, not only the adjusting bolt 62 but also the fixing bolt 64 is used to support the supporting member 30, so that the weight of the desktop board 10, the beam 20 and the supporting member 30 can be distributed, so that each adjusting bolt 62 and the fixing bolt 64 can be used to support. And, the load transmitted to the adjustment bolt 62 and the fixing bolt 64 is supported by the floor surface F through the substantially plate-shaped support plate 61 . Therefore, the load generated by the tabletop 10, the beam 20, and the support member 30 is distributed to the entire lower surface of the support plate 61 and then supported by the floor surface F, thereby preventing the floor surface F from being damaged.

It is not necessary to equip two adjustment bolts 62 as the adjustment mechanism, but only one. In this case, too, by providing two fixing bolts 64 , the adjustment with the adjusting bolts 62 is minimized, and the number of members supporting the tabletop 10 , the beam 20 and the support 30 can be increased.

In this embodiment, since two adjustment mechanisms 60 are provided in the width direction Y with respect to one support member 30, even if the floor surface F bulges or sags in the width direction Y directly under the support member 30, It can flexibly respond to changes in its inclination state, so that the entire lower surface of each support plate 61 abuts on the floor surface F, and the support member 30 can be supported with the height and levelness adjusted. In addition, the number of adjustment mechanisms 60 provided on the support member 30 is not limited to the above, and may be more than three, or may be only one. The former can respond more flexibly to the inclination state of the floor surface F, and the latter can minimize the adjustment of the adjustment bolt 62, which has the advantage of easier adjustment.

In this embodiment, the adjustment mechanism 60 is equipped with the first sleeve part 68, which prevents the adjustment bolt 62 and the fixing bolt 64 connected between the support member 30 and the support plate 61 from being exposed to the outside, so that the appearance is beautiful, and it can be compared with The support plate 61 adjusts the height and level of the support member 30 . In particular, in the adjustment mechanism 60 of this embodiment, since the second sleeve portion 69 is also provided, the adjustment bolt 62 and the fixing bolt 64 can be prevented from being exposed from the gap between the first sleeve portion 68 and the support member 30, and a more stable structure can be obtained. Beautiful appearance. In addition, only any one of the first sleeve portion 68 and the second sleeve portion 69 may be used.

As mentioned above, although the desk 1 was demonstrated as an example of the furniture to which the adjustment mechanism 40 was attached, it is not limited to this. The adjustment mechanism of the present invention is not limited to other desks with different structures, and can also be applied to various furniture such as shelves and partitions, especially suitable for supporting furniture with large length and width and heavy weight, and suitable for Make adjustments for height and level.
