Top board 3 persons' of being to use working space, in the present embodiment, this top board 3 is supported by the part of removing outside the rear end on shank 2 tops.This is because be provided with the opening of patchhole 7 in the rear end, top of shank 2.In addition, in the present embodiment, top board 3 has until near the depth the opening on shank 2 tops, do not have the part of opening (be top board 3 except about part the end), top board 3 also can have identical with the rear end of shank 2 or until the depth of the position after leaning on than the rear end of shank 2.

Fig. 3 is the cutaway view that the related patchhole of present embodiment 7 is shown.Be provided with the patchhole 7 that inserts for pillar 6 in the rear end of shank 2.The medial surface 71 of the rear side that is positioned at desk 1a in the medial surface of patchhole 7 is provided with a plurality of a plurality of fastenings holes 73 (with reference to Fig. 2) that hole 72 are set and are used for fastening back side cover 27 that are used to use slide mass anchor post 6 described later.Though omitted diagram,, cover 27 inboard overleaf and be provided with hook portion (hook), by making this hook portion fastening in fastening hole 73, thereby back side cover is installed in the back side of shank 2.

Fig. 4 is the cutaway view of the related pillar of present embodiment 6.In the present embodiment, the cross sectional shape of pillar 6 is a rectangle, and the cross sectional shape of patchhole 7 also is the rectangle corresponding with the cross sectional shape of pillar 6.And then pillar 6 and patchhole 7 form at pillar 6 and are inserted in the size that the side at four sides of the state lower supporting rod 6 of patchhole 7 contacts with the medial surface at the four sides of patchhole 7 just.

The cross section of pillar 6 is roughly rectangle, and has the groove that extends along its length in the side.Pillar 6 is to be used for panel or shelf etc. is arranged on parts on the top board 3 of desk 1a.The cross sectional shape of pillar 6 forms following shape: spaced walls 61 is extended from matrix part 60 towards four direction, and the quadrangle in the cross section of pillar 6 becomes summit Q.And then wall 62 extends from a summit Q towards another summit Q.The wall 62 that extends from summit Q and extend to the centre of two summit Q from the wall 62 that another summit Q extends always near, but the two does not contact.Therefore, between opposed wall 62,62 (hereinafter referred to as " a pair of wall 62 "), be formed with peristome 63.And, form slot part 64 by a pair of wall 62, spaced walls 61 and matrix part 60.These peristomes 63 and slot part 64 spread all over the total length extension of pillar 6 along the length direction of pillar 6.

This pillar 6 is inserted in patchhole 7.And then, in this pillar 6, utilize Fig. 5 slide mass extremely shown in Figure 8 highly pillar 6 being fixed in medial surface 71 arbitrarily, thereby can be provided for being provided with the pillar 6 of panel or shelf etc. the user.Below, this slide mass is described.

Slide mass is made of force application part shown in Figure 5 82 and matrix part 83 shown in Figure 6.These two parts are parts fully independently.Force application part 82 is made of following part: the force section 82a with contour shape; The jut 82b that gives prominence to from force section 82a towards a direction; And from the direction outstanding jut 82c opposite of force section 82a court with jut 82b.Force section 82a is provided with the linear line symmetry that becomes of the each point of jut 82b and jut 82c with respect to binding.Concrete being shaped as of force section 82a: (zone of representing with R1 in the drawings) is for slightly along the shape of the center line of line symmetry near each jut, further, the mode that (zone of representing with R2 in the drawings) left with the center line from the line symmetry when near force section 82a central forms circular shape, and (zone of representing with R3 in the drawings) forms the shape with the center line almost parallel of line symmetry near the central authorities of force section 82a.Force section 82a adopts this shape, thus, the force section in the zone of representing with R3 easily with the force section in the zone represented with R1 serve as axle along a direction deflection vertical with drawing, by this deflection, the 82a power that can play a role in the direction vertical in force section with drawing.And jut 82c roughly forms columned shape for lugs, and jut 82b forms the transverse width shape wideer slightly than the transverse width of jut 82c.In addition, this transverse width is slightly littler than the width of the peristome 63 of pillar 6.

As shown in Figure 6, matrix part 83 is provided with 3 screwed hole 83b in the central authorities of matrix part 83a.In addition, be provided with end difference 83c in the end face side of matrix part 83a along the length direction of matrix part 83a.In addition, the width of this end difference 83c (width of drawing above-below direction) is slightly littler than the width of the peristome 63 of pillar 6.

According to Fig. 7 above-mentioned force application part 82 and matrix part 83 are described as the situation of slide mass performance function in the slot part 64 of pillar 6.Shown in Fig. 7 is the situation of the slide mass in the slot part 64 of pillar 6.As mentioned above, slot part 64 is formed by each internal face of 60 extended spaced walls 61 and wall 62 from central division, and its cross sectional shape is hexagon roughly., as shown in Figure 7, the roughly hexagonal summit in the cross section of slot part 64 is called S1 to S6 herein, and the summit that will constitute peristome 63 is called T1, T2.

At first, shown in Fig. 7 (a), make force application part 82 slip into slot part 64 from peristome 63.At this moment, jut 82c is positioned near the depth portion (summit S3, the S4) of slot part 64, and jut 82b is positioned near peristome 63 (between summit T1, the T2).And, force section 82a in the part of region R 3 between the summit of slot part 64 S1, the S2 and near the internal face between summit S5, the S6.At this moment, between force section 82a and this internal face, have a little gap, so force section 82a does not become deflected.

Under the state shown in Fig. 7 (a), can force application part 82 be moved freely in the slot part 64 of pillar 6 via jut 82b.Making after force application part 82 moves to the optional position of slot part 64, shown in Fig. 7 (b), matrix part 83 is inserted in the slot parts 64.At this moment, in matrix part 83, the face that is not provided with end difference 83c of matrix part 83 contacts with the face of the side that is extruded with jut 82b of the force section 82a of force application part 82, and this end difference 83c is positioned at peristome 63.

In the state shown in Fig. 7 (b), because the force section 82a of force application part 82 is pressed into the depth portion of slot part 64 by matrix part 83, so the part that is positioned at region R 3 of force section 82a contacts with the internal face that is formed by spaced walls 61 (between summit S2, the S3 and between summit S4, the S5).This internal face is along with before the depth portion of slot part 64 and then narrowed width.Therefore, under the state shown in Fig. 7 (b), the force section 82a deflection in the above described manner of force application part 82 because this deflection, produces matrix part 83 by the active force near the wall 62 that is pressed in the peristome 63.Consequently, the slide mass that is made of force application part 82 and matrix part 83 is fixed in the optional position in the pillar 6.

And then the hole 72 that is provided with of passing the fixedly usefulness of the medial surface 71 of being located at patchhole 7 is anchored on the screwed hole 83b that is fixed on the slide mass in the pillar 6 from the outside with screw, thus, pillar 6 can be erect and be arranged at shank 2.

Situation when herein, according to Fig. 8 the fixed position of the slide mass that temporarily is fixed in the optional position being changed describes.At first, shown in Fig. 8 (a), the matrix part 83 of having given active force by force application part 82 is moved, towards the direction of arrow up to moving to the position that can not be subjected to the active force of force application part 82 fully.At this moment, when from profile direction observation slot part 64, become the situation shown in Fig. 8 (b).Matrix part 83 breaks away from, and force application part 82 becomes the state shown in Fig. 8 (b) thus.At this moment, force application part 83 is present in space in addition, force application part 82 existing spaces in slot part 64.

But shown in Fig. 8 (b), matrix part 83 becomes in slot part 64 state that the jut 82c with force application part 82 interferes.This means that even if matrix part 83 is in the state that discharges from the active force that is produced by force application part 82, this matrix part 83 also can't move freely in slot part 64, it moves by force application part 82 restrictions.Thus, can avoid matrix part 83 inadvertently to break away from from force application part 82.In addition, with matrix part 83 after the active force that is produced by force application part 82 discharges, matrix part 83 is taken out from peristome 63, and, can carry out fixing of slide mass thus in that force application part 82 is inserted matrix part 83 in the slot parts 64 after moving to new position once more.

In addition, when object parts such as beam 9, panel and shelf are installed on pillar 6, also can use identical slide mass above-mentioned object parts to be installed on the optional position of pillar 6.

Below, the step that pillar 6 is installed on shank 2 in the present embodiment is described.Fig. 9 A to Fig. 9 E is the figure that pillar 6 is installed on the step of shank 2 that illustrates in the present embodiment.At first, back side cover 27 and the opening cover 29 that is arranged at shank 2 unloaded (with reference to Fig. 9 A).By back side cover 27 is unloaded, the pillar 6 fixedly hole 72 that is provided with of usefulness exposes at the back side of shank 2, by opening cover 29 is unloaded, supplies the opening of the patchhole 7 of pillar 6 insertions to expose (with reference to Fig. 9 B) at the upper surface of shank 2.

And slide mass is fixed in the optional position of the groove of pillar 6.Because the fixing step to slide mass is illustrated, therefore omit explanation.Herein, being predetermined the length how long that makes pillar 6 tops exposes above shank 2 or top board 3, then, slide mass is installed on pillar 6 bottoms as upper/lower positions: kept at pillar 6 under the state that is inserted in patchhole 7 behind the exposed length of above-mentioned decision with the pillar 6 that is arranged at shank 2 fixedly usefulness corresponding position, hole 72 is set.In addition, in order to ensure intensity and stability, plural slide mass is installed preferably.

Then, via opening pillar 6 is inserted in patchhole 7 (with reference to Fig. 9 C).The pillar 6 that inserts is so that be equipped with the position of slide mass and the mode of the position consistency that hole 72 is set of medial surface 71 is carried out contraposition.

And then in this position, the fixedly usefulness of the medial surface 71 by being located at patchhole 7 is provided with the screwed hole 83b that hole 72 is anchored on screw from the outside slide mass, and thus, pillar 6 is fixed in the medial surface 71 of patchhole 7, thereby pillar 6 is erect and is arranged at shank 2.At last, once more back side cover 27 is installed on shank 2 back sides, thus, the installing of pillar 6 (with reference to Fig. 9 D).

In addition, the pillar installation constitution related according to present embodiment owing to slide mass can be fixed in the optional position, therefore freely adjustable fixing height (with reference to Fig. 9 E) is set.
