FIG. 11 is a perspective view showing an example of a coupling member applied to another embodiment;

Referring to FIG. 1 , a stand board 10 of the present embodiment includes a board body 20 and leg members (support members) 30 that support the board body 20 . For convenience of explanation, the width direction of the standboard 10 is assigned to the X axis, the thickness direction of the standboard 10 is assigned to the Y axis, and the height direction of the standboard 10 is assigned to the Z axis. At this time, the front surface of the stand board 10 faces the negative side in the Y-axis direction, and the rear surface of the stand board 10 faces the positive side in the Y-axis direction.

As shown in FIG. 2, the inner frame 26 of the board body 20 corresponds to two stile members 26t extending in the Z-axis direction at a distance corresponding to the width of the board body 20 and the height of the board body 20. and two stile members 26h extending in the X-axis direction at a distance of . Here, the stile members 26t and 26h are made of wood, and both the width and thickness are approximately the same between the stile members 26t and 26h.

However, strictly speaking, the width (size in the Z-axis direction) of the stile member 26h arranged on the lower side is slightly larger than the width (size in the Z-axis direction) of the stile member 26h arranged on the upper side. As for the lower stile member 26h, the thickness (size in the Y-axis direction) of the upper end (the positive side end in the Z-axis direction) is made thinner than the thickness of the other portions (FIG. 5A). , see FIG. 5B).

Further referring to FIG. 3, of the upper end surface of the lower stile member 26h (the surface facing the positive side in the Z-axis direction), each of the positive side end and the negative side end in the X-axis direction has X Two through holes HL1 extending in the Z-axis direction are formed at two positions separated by a distance D1 in the axial direction. A plate nut (base material) 40 is a steel base material having a length exceeding the distance D1, and is attached to the upper end surface of the lower stile member 26h so as to straddle the two through holes HL1. .

More specifically, referring to FIG. 4, the length of the plate nut 40 (size in the X-axis direction) slightly exceeds the distance D1, and the width of the plate nut 40 (size in the Y-axis direction) is The thickness of the plate nut 40 (the size in the Z-axis direction) substantially matches the thickness of the upper end portion of the stile member 26 h , and is much smaller than the width of the plate nut 40 .

Two through-holes 40h1 extending in the Z-axis direction are formed in the main surface of the plate nut 40 (the surface facing the positive side or the negative side in the Z-axis direction) at two positions separated by a distance D1 in the X-axis direction. be done. A female screw is formed on the inner peripheral surface of each of the two through holes 40h1.

The main surface of the plate nut 40 is also formed with two through holes 40h2 extending in the Z-axis direction at two positions separated by a distance D2 in the X-axis direction. Here, the distance D2 is shorter than the distance D1, and the positions where the two through-holes 40h2 are formed are positioned between the two through-holes 40h1.

The plate nut 40 is arranged on the upper end surface of the lower stile member 26h so that the two through holes 40h1 communicate with the two through holes HL1 respectively. In this state, the fixing screw 42 is inserted into each of the two through holes 40h2 from the positive side in the Z-axis direction. The tip of the inserted fixing screw 42 protrudes from the negative side in the Z-axis direction and is screwed into the lower stile member 26h. As a result, the plate nut 40 is attached to each of the positive side end portion and the negative side end portion in the X-axis direction of the upper end surface of the lower stile member 26h.

Returning to FIG. 2, the outer frame 24 is provided on the outer edge of the inner frame 26, having four through holes (not shown) respectively communicating with a total of four through holes HL1 formed in the stile member 26h. Also, the plate member 28 is made of a foaming material and arranged in a hollow portion inside the inner frame 26 . When viewed from the Y-axis direction, the size of the plate member 28 substantially matches the size of the area surrounded by the inner frame 26 . Also, the thickness (size in the Y-axis direction) of the plate member 28 substantially matches the thickness of each of the stile members 26h and 26t.

The size of the main surface of the panel 22 substantially matches the size of the area surrounded by the outer frame 24, and the thickness (size in the Y-axis direction) of the panel 22 is significantly thinner than the thickness of each of the stile members 26h and 26t. . The panel 22 is provided on each of the front and rear surfaces of the board body 20 so as to cover the inner frame 26 and the plate member 28 when viewed from the Y-axis direction.

Note that the panel 22 is assumed to be a white board on which writing is possible, a pinable cloth, or the like. Alternatively, a white board may be used as the front panel 22 and a cloth may be used as the rear panel 22 .

Referring to FIG. 3, leg members 30 are attached to each of the positive and negative ends in the X-axis direction of the lower end surface of the board body 20 (the surface facing the negative side in the Z-axis direction). be done. When viewed from the positive side in the X-axis direction, the leg member 30 includes a front leg 32f curved in an inverted S shape and a rear leg 32b curved in an S shape. A front wheel 36f is attached to the tip of the front leg 32f, and a rear wheel 36b is attached to the tip of the rear leg 32b. A base end of each of the front leg 32f and the rear leg 32b is coupled to the leg base plate 34. As shown in FIG. The front leg 32f, the rear leg 32b and the leg plate 34 are all made of steel and are integrally formed.

The length of the leg plate 34 (size in the X-axis direction) slightly exceeds the distance D1, and the width of the leg plate 34 (size in the Y-axis direction) is greater than the width of the board body 20 (size in the Y-axis direction). slightly lower. Two through holes 34h extending in the Z-axis direction at two positions separated by a distance D1 in the X-axis direction are formed on the main surface of the leg base plate 34 (the surface facing the positive side or the negative side in the Z-axis direction). It is formed. The connecting position of the proximal end of each of the front leg 32f and the rear leg 32b is a position sandwiched between the two through holes 34h.

The leg member 30 is arranged on the lower end surface of the board body 20 so that the two through holes 40h1 communicate with the two through holes HL1 respectively. In this state, a steel fixing bolt (coupling member) 38 is inserted into each of the two through holes 34h from the negative side in the Z-axis direction. The tip of the inserted fixing bolt 38 protrudes from the upper end (positive end in the Z-axis direction) of the through hole HL1 and is screwed into the through hole 40h1 of the plate nut 40 . That is, the male thread formed on the tip of the fixing bolt 38 engages with the female thread formed on the inner peripheral surface of the through hole 40h1. As a result, the leg member 30 is attached to each of the positive side end and the negative side end in the X-axis direction of the lower end surface of the board body 20 .

As shown in FIGS. 5(A) and 5(B), the lower stile member 26h is thinner at the upper end than at the other portions. Therefore, even if the fastening strength of the fixing bolt 38 is too strong and the upper end portion of the stile member 26h swells (see FIG. 5B), the surface of the upper end portion does not contact the panel 22, and the panel 22 is secured. No loss of flatness.

As can be seen from the above description, the stand board 10 includes a board body 20 and leg members 30 that support the board body 20 . The board body 20 also includes a lower stile member 26h formed with a through hole HL1 extending in the Z-axis direction, and a plate nut 40 provided on the lower stile member 26h inside the board body 20. and Based on this, the fixing bolt 38 is coupled with each of the plate nut 40 and the leg member 30 through the through hole HL1.

By passing the fixing bolt 38 through the through hole HL1 extending in the Z-axis direction, the size of the stand board 10 in the front-rear direction at the attachment portion of the leg member 30 can be suppressed. Further, by coupling the fixing bolt 38 to the plate nut 40, it is possible to reduce the concern that the board body 20 will be damaged by the load exerted by the fixing bolt 38 on the lower stile member 26h.

Further, since the steel fixing bolt 38 and the plate nut 40 are harder than the wooden stile member 26h, the tip of the fixing bolt 38 protrudes from one end of the through hole HL1 and engages with the plate nut 40. . As a result, there is less concern that the tip of the fixing bolt 38 will be overloaded and the stile member 26h will be damaged.

Further, a plate nut 40 is attached to the stile member 26h with a length exceeding the distance D1, and two fixing bolts 38 engage one plate nut 40. As shown in FIG. As a result, the concern that the plate nut 40 will distort the stile member 26h due to the tightening of the fixing bolt 38 is alleviated.
[Modification]
(1) In the above-described embodiment, the fixing bolt 38 is separate from the plate nut 40 . However, as shown in FIG. 6, instead of the fixing bolt 38 and the plate nut 40, a connecting member 50 integrally formed of two columnar members 38' each having a male thread at the tip thereof and a plate member 40' is employed. You may do so.

In this case, the two columnar members 38' are inserted into the two through holes HL1 from the inside of the board body 20, respectively. The leg member 30 is attached to the board body 20 by passing the tip of the columnar member 38' through the through hole 34h of the leg base plate 34 and screwing a nut (not shown) onto the tip protruding downward of the through hole 34h.

(2) In the above-described embodiment, the through hole HL1 extends in the Z-axis direction. You may make it extend.

(3) In the above-described embodiment, the leg members 30 are assumed as supporting members for supporting the board body 20 . However, when mounting the board body 20 to a wall, arm members are envisioned as support members. Further, when the board body 20 is supported by arm members, the through holes HL1 and the plate nuts 40 must be provided in the left and right stile members 26t.

(4) In the above embodiment, the stile members 26h and 26t are made of wood, but the stile members 26h and 26t may be made of synthetic resin.
