A screw hole 28c is bored through the fitting protrusion 28 inward and outward along the inclined side, and an engagement recess 28d is provided at a predetermined location on the inner surface.

  On the other hand, as shown in FIG. 10, a fitting groove portion 5 b having a substantially isosceles trapezoidal shape corresponding to the fitting protrusion 28 of the support arm 6 is formed on the front and rear center side of the inner surface of the leg member 5. ing. The fitting groove portion 5b is formed by scraping the inner side surface and the upper surface of the leg member at the front and rear center sides to a predetermined depth, that is, opening inward and upward.

  As shown in FIG. 7, brackets (not shown) used when a panel (not shown) is erected on the left and right edges of the top plate 2 in the two protruding portions 21 on the front and rear sides of the support arm 6. A screw hole 21b for connection is formed. When the panel is not used as in this embodiment, the support arm outer opening communicating with the overhanging portion 21 is closed by the lid member 33.

  As shown in FIGS. 9 and 14, screw holes 6 a are formed at a plurality of locations separated from the fitting protrusion 28 on the upper surface of the support arm 6 in both the front and rear directions (longitudinal direction), and the leg member 5. A screw (not shown), which is a screwing means for screwing, can be inserted.

  Next, assembly of the support arm 6 to the leg member 5 will be described.

  First, as shown in FIG. 7, two peripheral members 30 are attached in the front-rear direction along the groove 22 on the lower surface of the support arm 6, and the support arm 6 is installed at a predetermined position on the upper surface of the leg member 5. As shown in FIGS. 8A, 8 </ b> B, and 9, the projecting pieces 30 c and 30 d provided at two locations on each peripheral member 30 are fitted into the fitting holes 22 c and 22 d of the groove portion 22, respectively. Thus, even if the lower surface of the support arm 6 to which the peripheral member 30 is attached is directed downward, the peripheral member 30 does not fall out of the support arm 6, and the peripheral member with respect to the fitting holes 22 c and 22 d of the support arm 6. Since the 30 protruding pieces 30c and 30d can be assembled to the leg member 5, the assembly efficiency of the entire desk 1 is improved. Thus, the peripheral member 30 is clamped by the support arm 6 and the upper surface 5a of the leg member 5 when the support arm 6 is attached.

  As shown in FIGS. 13 to 15, when the metal support arm 6 is installed on the upper surface 5 a that is the decorative surface of the wooden leg member 5 and the leg member 5 and the support arm 6 are attached by screwing means, If the support arm 6 formed of a rigid body is subjected to concentrated stress on the upper surface 5a of the wooden leg member 5, there is a risk that wrinkles and bending may occur, but the peripheral member 30 formed of an elastic member serves as a buffer member. The leg member 5 is prevented from being damaged or deformed.

  In particular, the groove portions 22 provided in the outer peripheral edge portion of the lower surface of the support arm 6 are provided in the outer peripheral edge and the front and rear peripheral edges, and the peripheral members 30 are arranged on the outer peripheral edge and the front and rear peripheral edges that are conspicuous from the outside of the furniture. By doing so, it is possible to reliably hide the bag etc. from the outside.

  Moreover, since the sectional view shape in the width direction of the peripheral member 30 is an inclined shape having an inclined surface 30b that expands toward the upper surface 5a of the leg member 5, the load of the support arm 6 and the top plate 2 applied from above is applied to the contact area. Therefore, the support arm 6 can be stably held.

  Further, as described above, the lower surface of the support arm 6 is installed on the upper surface 5 a of the leg member 5, and at the same time, the substantially isosceles trapezoidal fitting protrusion 28 of the support arm 6 is formed on the inner groove of the leg member 5. Approach and fit 5b. By fitting the fitting protrusion 28 into the fitting groove 5b, positioning in the front-rear direction and the left-right direction with respect to the leg member 5 of the support arm 6 is performed.

  After fitting the fitting protrusion 28 into the fitting groove 5b, the connecting bolt 34 inserted into the screw hole 28c of the fitting protrusion 28 is screwed into the leg member 5 (see FIG. 15), thereby supporting The fitting projection 28 of the arm 6 is fixed to the fitting groove 5 b of the leg member 5.

  Thus, the fitting protrusion 28 of the support arm 6 is fitted into the fitting groove 5b of the leg member 5, whereby the rigidity of the leg member 5 can be increased. Moreover, since both the fitting protrusion 28 and the fitting groove part 5b were made into the trapezoid shape which narrows toward the downward direction, it becomes easy to insert the fitting protrusion 28 in the fitting groove part 5b.

  Specifically, when the fitting protrusion 28 is inserted from the upper side toward the lower fitting groove 5b, the lower bottom side 28a, which is the narrow tip of the fitting protrusion 28, is fitted in the initial stage of insertion. It is easy to insert into the wide opening of the joint groove 5b, and thereafter, as the fitting protrusion 28 is inserted into the fitting groove 5b, the outer surface of the fitting protrusion 28 comes into contact with the inner surface of the fitting groove 5b and is gradually positioned. However, the fitting protrusion 28 is fitted at a predetermined fitting position.

  In addition, since the fitting groove 5b is opened upward as described above, the fitting protrusion 28 can be easily fitted into the fitting groove 5b.

  After the fitting protrusion 28 is fixed to the fitting groove 5b with the connecting bolt 34, as shown in FIGS. 12 (a), 12 (b), 13 and 15, the fitting groove portion. A closing plate 31 having a substantially isosceles trapezoidal shape substantially the same as the shape of the side opening 5b is engaged with the fitting protrusion 28 fitted in the fitting groove 5b. The closing plate 31 has a flat surface with a peripheral edge 31a slightly protruding on the front surface, and an engagement convex portion whose front end bulges at a predetermined position on the back surface corresponding to the engagement concave portion 28d of the fitting protrusion 28. 31b is provided.

  By aligning the closing plate 31 with the fitting projection 28 and pressing it toward the fitting projection 28, the engagement projection 31 b is engaged with the engagement recess 28 d, and the closure plate 31 is moved to the fitting projection 28. Install. The closing plate 31 attached to the fitting protrusion 28 is substantially flush with the inner side surface 5 c of the leg member 5.

  As shown in FIG. 15, the side opening of the fitting groove 5 b is open toward the other leg member 5, that is, inward, so that it does not stand out from the outside of the desk 1, and the closing plate 31. Therefore, the connecting bolt 34 and the fitting protrusion 28 are not exposed to the outside, and the appearance is not impaired.

  Further, as described above, the shape of the closing plate 31 is substantially the same as the shape of the side opening of the fitting groove portion 5b of the leg member 5, and the inner side surface 5c and the substantially surface which are the opening side of the fitting groove portion 5b of the leg member 5. Since it is one, there is no sense of incongruity of unevenness, it can be made the same as the inner side surface 5c of the leg member 5, and the appearance is good.

  Next, as shown in FIG. 14, a mounting screw (not shown) inserted downward into a screw hole 6 a formed on the upper surface of the support arm 6 is screwed with the leg member 5, whereby the support arm 6 is attached to the leg. Fix to the member 5.

  As described above, the fitting projection 28 is connected to the fitting groove 5b at a substantially intermediate position in the front-rear direction (longitudinal direction) of the support arm 6 and is separated from the fitting projection 28 in both longitudinal directions. Since the screw inserted into the screw hole 6a is connected to the leg member 5, the rigidity of the leg member 5 increases in the entire region in the longitudinal direction. In addition, the said several location connected with the leg member of a support arm should just be spaced apart from the fitting protrusion in both directions of a longitudinal direction, for example, may be the both ends location before and behind a support arm.

  In addition, the fitting protrusion 28 is formed such that the lower base side 28a is shorter than the upper base side 28b, and the inclined sides on the front and rear sides of the fitting protrusion 28 are narrowed toward the lower base side 28a. Since the lower bottom side 28a of the fitting projection 28 and the inclined side are difficult to enter from the outside of the desk 1, the fitting projection 28 and the closing plate 31 are not conspicuous and the appearance is good.

  Next, the connection between the support arm 6 and the connecting rod 7 will be described.

  In the present embodiment, only one connecting rod 7 is connected to the support arm 6 using the insertion hole 24 a located at the front and rear center of the support arm 6. As shown in FIGS. 11A, 11B and 13, the connecting rod 7 is a tubular body with an internal structure composed of a peripheral wall having a rectangular shape in side view, and is slightly more than the left and right end edges of the connecting rod 7. Inwardly, a plate member 32 in which a pair of front and rear bolt holes 32a is formed is fixed to the connecting rod 7 in a state where it is inclined at a predetermined angle with respect to the upper and lower peripheral walls. Specifically, the plate member 32 is inclined at an angle so as to be substantially parallel to the tapered surface 24 b of the upright piece 24 of the support arm described above at the attachment position of the connecting rod 7. The bolt hole 32a is formed in a direction substantially orthogonal to the inner and outer end surfaces of the plate member 32. That is, the bolt hole 32a is substantially orthogonal to the tapered surface 24b of the standing piece 24 at the attachment position of the connecting rod 7. The insertion hole 24a is formed so that it can be arranged substantially coaxially.

  The connecting rod 7 is arranged so that the bolt hole 32 a of the plate member 32 is substantially coaxial with the insertion hole 24 a of the standing piece 24 of the support arm 6. Specifically, the connecting rod 7 is fitted such that the upper and lower peripheral edges of the connecting rod 7 having the inner structure are fitted to the positioning pieces 27 protruding from the outer surface of the standing piece 24 of the U-shaped portion 23. Deploy.

  Next, as shown in FIG. 13, connecting bolts B, which are bolts connecting the support arm 6 and the connecting rod 7, are inserted into the respective insertion holes 24 a from the outer upper side to the inner lower side of the U-shaped portion 23. And insert it diagonally. Each connecting bolt B is inserted into the insertion hole 24a and screwed into the bolt hole 32a.

  In this embodiment, only the pair of insertion holes 24a formed at the front and rear centers are used to connect the support arm 6 and only one connecting rod 7, but the top and bottom width dimensions and The support arm 6 and the plurality of connecting rods may be connected to each other by using several pairs of insertion holes as appropriate among the plurality of insertion holes formed according to the load-bearing specifications.

  As described above, since the plurality of insertion holes 24a of the connection bolt B are drilled, the number and installation locations of the connection rods can be arbitrarily selected according to the location of the insertion hole 24a. Further, by providing the ribs 26 between the adjacent insertion holes 24 a, the moment generated by the fastening of the connecting bolt B of the connecting rod 7 can be applied to the U-shaped portion 23 of the support arm 6 connected by the ribs 26. It can be received by the compatible pieces 24 and 25, and the support strength of the connecting rod 7 can be increased.

  The connecting rod 7 is connected by two connecting bolts B inserted through two adjacent insertion holes 24a. The connecting rod 7 is connected by the two connecting bolts B and between the adjacent insertion holes 24a. Since the rib 26 is provided, the support strength of the connecting rod 7 can be further increased.

  In addition, the positioning piece 27 can hold the connecting rod 7 in the vertical direction with respect to the support arm 6 as a leg portion, so that the connecting bolt B can be fastened while the heavy connecting rod 7 is supported by the positioning piece 27. it can. Further, since the positioning piece 27 protrudes from the outer surface of the inner standing piece 24 of the U-shaped portion 23, the standing piece 24 becomes thicker, and the support strength of the connecting rod 7 is increased. It can contribute to improvement.

  Furthermore, by forming the inner surface of the inward standing piece 24 in which the insertion hole 24a is drilled into the tapered surface 24b that is inclined outward and upward, the connecting bolt B can be inserted obliquely from the upper outside. The connecting bolt B can be fastened without increasing the distance between the compatible pieces 24 and 25, and the thickness in the width direction of the support arm 6 as the leg portion can be reduced.
