As shown in Fig. 2, the pipe body 12 has a bottom plate 12A, a base side plate 12B, and a base end plate 12C. The base side plates 12B and 12B face each other on the right and left long sides of the rectangular bottom plate 12A and the base end plate 12C faces the front and rear short sides of the bottom plate 12A. The tops formed of the bottom plate 12A, the base side plate 12B and the base end plate 12C serve as the base of the tube main body 12 and serve as a portion for securing the strength of the tube 10.

As shown in Fig. 4, a flat rectangular concave portion is formed on the bottom surface of the base side plate 12B and the base end plate 12C. Then, the bottom plate 12A is accommodated in this recess, and the nail P is stuck from the rear side and fixed. By adopting the accommodating structure of the bottom plate 12A, the front, rear, left and right end faces of the bottom plate 12A, that is, the cross section in the thickness direction of the bottom plate 12A, ). Further, since the head portion of the nail P faces downward, the appearance of the outer surface of the pipe body 12 is improved.

On the upper side of the base side plate 12B, a provisional side plate 12X is provided (see Figs. 2 and 4). The guiding type side plate 12X is vertically connected to the base side plate 12B and the hinge hinge 15 on the inside of the tube. The base side plate 12B and the movable side plate 12X are aligned with each other to form a side surface (a plate surface viewed in the lateral direction) of the tube body 12. [

The hinge hinge 15 is made of metal, resin, or the like, and is arranged at least at two or more intervals in a longitudinal direction (front-rear direction) (see Figs. 1 and 2). By these hinge hinge 15, the guiding type side plates 12X and 12X lie on the side of the bottom plate 12A. That is, the guiding type side plates 12X and 12X are folded inward and inward from the standing posture of Fig. 4 (see Fig. 5).

The insertion end plates 12Y and 12Y are pushed in at positions adjacent to the base side plate 12B and the guiding side plate 12X as front and back outer sides of the base end plate 12C (see Fig. 2). The insertion end plate 12Y forms an end surface (a plate surface viewed in the front-rear direction) of the tube main body 12. When the insertion end plate 12Y is pushed outwardly and backwardly of the base end plate 12C, The side plate 12X and the base side plate 12B. As a result, the standing posture of the movable side plates 12X and 12X is supported by the inserted end plate 12Y.

The left and right heights of the left and right base side plates 12B are set so as to have step differences. 4, the left base side plate 12B is substantially equal to the height of the base end plate 12C and the height of the right base side plate 12B is larger than the height of the base side plate 12B As shown in Fig. When the left and right base side plates 12B are folded inward, the base side plates 12B and 12B are superimposed on the base end plate 12C so as to be in a compact shape 5).

As shown in Fig. 3, the positional relationship between the base end plate 12C and the base side plate 12B is such that the base end plate 12C is sandwiched between the base side plates 12B and 12B facing each other in the left-right direction . On the other hand, the positional relationship between the guiding type side plate 12X and the insertion end plate 12Y is such that the insertion side plate 12Y is disposed outside the tube of the guided type side plate 12X, (Inverted structure) fitted in the insertion end plate 12Y. By disposing the movable type side plate 12X and the inserted type end plate 12Y in a reciprocal relationship with each other in this manner, the lower engaging projections 17 and the upper engaging projections 18), and it is possible to cover the boundary (cut-off mark) of the end surface of the tube main body 12 with the insertion end plate 12Y.

The engaging grooves 16, the lower engaging protrusions 17 and the upper engaging protrusions 17 are formed at positions facing each of the movable side plate 12X and the insertion end plate 12Y, 18).

An upper engaging projection 18 is provided on the front and rear end faces of the guiding type side plate 12X along the height direction and a lower engaging projection 17 is provided on the front and rear end faces of the base side plate 12B with the upper engaging projections 18 As shown in Fig. The engaging grooves 16 are provided at the right and left ends of the inner surface of the insertion end plate 12Y.

When the insertion end plate 12Y is pushed into a position adjacent to the front and rear outer sides of the movable side plate 12X, the engagement groove 16 is slid from the upper engagement projection 18 to the lower engagement projection 17 And the insertion end plate 12Y is connected to the movable side plate 12X in the standing position.

As shown in Fig. 8, the engaging portion between the engaging groove 16 and the lower engaging projection 17 and the upper engaging projection 18 is substantially trapezoidal in cross-section and extends in the longitudinal direction . The engaging groove 16 is shaped like a dovetail groove and the width of the groove bottom is wider than the width of the opening so that the lower engaging projection 17 and the upper engaging projection 18 The tip of the projection is wide. When the engaging grooves 16 are slidably inserted into the lower engaging protrusions 17 and the upper engaging protrusions 18, the respective protrusions 17 and 18 are accommodated in the engaging grooves 16 with almost no gap. As a result, the engaging grooves 16, the lower engaging projections 17, and the upper engaging projections 18 can move in the groove longitudinal direction (height direction), but can move in the groove depth direction So that the insertion end plate 12Y is detachably connected to the movable type side plate 12X.

7) and a cover portion (not shown) for hiding these joints are provided above the engaging means (the engaging groove 16, the lower engaging projection 17 and the upper engaging projection 18) 19b (see Fig. 6) are provided. The gap portion 19a is a space formed above the upper engagement projections 18 by providing the upper engagement projections 18 at a position lower than the upper end of the movable side plate 12X and the cover portion 19b is located at a position above the insertion end plate 12Y ) Of the insertion end plate 12Y formed at a position lower than the upper end of the insertion end plate 12Y by providing the engagement groove 16 at a position lower than the upper end of the insertion end plate 12Y.

When the engaging groove 16 is slid over the lower engaging projection 17 from the upper engaging projection 18, the cover portion 19b is received in the cavity portion 19a, The lower engaging projection 17 and the upper engaging projection 18 are hidden inside.

The cover portion 19b is mounted on the upper engaging projection 18 while the cover portion 19b is accommodated in the cavity portion 19a and the insertion end plate 12Y and the movable side plate 12X) are arranged so as to be aligned (see FIG. 9). That is, the height position of the insertion end plate 12Y is determined by the position and thickness of the cover portion 19b.

As shown in Fig. 7, the upper edge portions of the lower engaging projections 17 and the upper engaging projections 18 are chamfered so that the width gradually narrows toward the upper side when viewed from the front. When the engaging grooves 16 are fitted to the tips of the lower engaging projections 17 or the upper engaging projections 18, these chamfer portions serve to guide the engaging grooves 16 on the center line of each projection do. As a result, the pushing operation of the insertion end plate 12Y is performed smoothly.

As shown in Fig. 10, locking means comprising a lock pin L1 and lock holes h0 and h1 is provided in the vicinity of the base end plate 12C and the insertion end plate 12Y. The lock hole h0 is provided at a predetermined depth on the inner surface of the insertion end plate 12Y and the lock hole h1 is provided to penetrate through the base end plate 12C.

The lock hole h0 and the lock hole h1 come to a position where the insertion end plate 12Y is pushed in close to the base end plate 12C. At this time, the lock pin L1 is fitted in the lock holes h0 and h1, so that the insertion end plate 12Y is fixed so as not to come up.

By providing such a locking means, it is possible to stabilize the inserted state of the insertion end plate 12Y at the time of assembly, and to improve the reliability in use of the tube.

Next, a method of assembling the tube main body 12 will be described.

Before the pipe 10 is used, the movable side plate 12X of the pipe body 12 is folded inward (see Fig. 5), and the insertion end plate 12Y is missing. When assembling the tube main body 12 in this state, first, the movable side plate 12X on the right side in Fig. 5 is set up and the movable side plate 12X on the left side is set up. Then, the right and left movable type side plates 12X and 12X are temporarily held in an upright posture with an auxiliary plate (not shown) or the like.

Next, as shown in Fig. 2, the insertion end plate 12Y is pushed in front of and behind the movable type side plate 12X. At this time, when the engaging groove 16 of the insertion end plate 12Y is slidly inserted from the upper engaging projection 18 of the movable side plate 12X to the lower engaging projection 17 of the base side plate 12B The insertion end plate 12Y is connected to the movable side plate 12X and the base side plate 12B so as to be supported by the insertion end plate 12Y in the standing position of the movable side plate 12X.

Thereafter, the lock pin L1 is inserted into the above-mentioned lock holes h0 and h1 to fix the upward movement of the insertion end plate 12Y.

After assembling the tube main body 12 as described above, the assembly of the tube 10 is completed by mounting the previously prepared lid 3 above the tube main body 12 as shown in Fig. 1 .

When the tube main body 12 is folded, the locking means (lock holes h0, h1 and lock pin L1) are disengaged in the reverse order to that described above, the insertion end plate 12Y is pulled out upward, The left side guiding type side plate 12X and the right side guided type side plate 12X are folded right and left in this order on the base end plate 12C.

According to the pipe 10 of the first embodiment, when the insertion end plate 12Y is connected to the base side plate 12B and the guiding type side plate 12X so that the engaging grooves 16 are engaged with the upper engaging projections 18 And the cover portion 19b is accommodated in the cavity portion 19a so that the upper engaging protrusion 18 and the lower engaging protrusion 17 are inserted into the engaging groove 16 ) Is hidden. Therefore, the joints (the engagement grooves 16 and the upper engagement projections 18) between the movable side plate 12X and the insertion end plate 12Y are not visible on the upper portion of the pipe body 12. The joints (the engagement grooves 16 and the lower engagement projections 17) between the base side plate 12B and the insertion end plate 12Y can not be seen from the outer surface of the pipe body 12 as well.

In the tube 10, since the insertion end plate 12Y is disposed adjacent to the front and rear outer sides of the base end plate 12C, the base side plate 12B, and the movable side plate 12X, (Truncated mark) of the base end plate 12C, the base side plate 12B, and the movable side plate 12X can be hidden by the insertion end plate 12Y. Therefore, the boundary (cut-off mark) between the plate members is eliminated on the end surface of the tube main body 12 (see Fig. 1).

As a result, it is possible to greatly improve the finish of the outer appearance of the pipe 10 after the assembly, in conjunction with the effect of concealing the joint between the caulked side plate 12X and the insertion end plate 12Y.

Since the arrangement of the insertion end plate 12Y is such that the base end plate 12B and the movable side plate 12X are arranged at the front and rear ends of the base end plate 12C, The upper engaging protrusion 18 and the lower engaging protrusion 17 can be provided on the end surface. As a result, these engaging projections can be formed in the thickness range of these side plates, and the strength of the seams (the engaging grooves 16, the upper engaging projections 18 and the lower engaging projections 17) It is possible to keep it.

More specifically, if a circular plate which is longer than the length of the base side plate 12B by the distance of the lower engaging projection 17 is prepared and the front and rear ends of the circular plate are cut, the lower engaging projection 17 can be simply . Similarly, a circular plate (a circular plate having the same length as the circular plate of the base side plate 12B) longer than the length of the guarded side plate 12X by an amount corresponding to that of the upper engagement projections 18 is prepared, By machining, the upper engaging projection 18 can be simply formed.

Since the engagement groove 16 is provided at the end of the inner side surface of the insertion end plate 12Y for the machining of the engaging groove 16, the plate surface is subjected to a cutting process so that the thickness of the insertion end plate 12Y The engaging groove can be formed.

As a result, it is possible to simplify the processing of the joint between the guard-type side plate 12X and the insertion end plate 12Y and the joint between the base side plate 12B and the insertion end plate 12Y, . In addition, since the engaging projections do not protrude from the surface of the base side plate 12B and the movable side plate 12X, the strength of these seams can be sufficiently secured.

[Second Embodiment]

Next, the assembled pipe of the second embodiment is shown in Figs. 11 to 19. Fig. The tube 20 of the second embodiment employs a corrugated cardboard hinge 25 for the tube body 22. Since the basic construction and effect of the pipe are the same as those of the first embodiment, substantially the same constituent parts are given the same reference numerals.

As shown in Fig. 11, the tube 20 includes a tube main body 22 and a lid 23. A lid (23) is mounted on the tube main body (22) so as to be openable and closable. A window unit (W) is provided at a position in front of the lid (23). The window unit W is equipped with a double-sided door, which can be seen through the inside of the tube by opening these doors.

As shown in Fig. 12, the tube main body 22 has a bottom plate 12A, a base side plate 22B, and a base end plate 12C. The base side plates 22B and 22B face each other on the left and right sides of the rectangular bottom plate 12A and the base end plate 12C faces the front and rear short sides of the bottom plate 12A.

On the upper side of the base side plates 22B, 22B, movable side plates 22X, 22X are provided. The guiding type side plates 22X and 22X of the standing posture can be folded right and left inside by the corrugated cardboard hinge 25. [

17, the lower engaging protrusion 17 and the upper engaging protrusion 18, and the lower engaging protrusion 18, as shown in Fig. 12 (a), on the front and rear outer sides of the base side plate 22B and the guiding side plate 22X, The insertion end plates 22Y and 22Y are connected and aligned.

Of the plate members constituting the tube main body 22, the outer wall portion of the base side plate 22B and the guiding type side plate 22X are integrally formed by a corrugated cardboard material having a multi-layer structure sandwiching a core material between the outer plate and the inner plate . As the corrugated board material, a double-layer reinforced corrugated board material (for example, manufactured by TRI-WALL) having a thickness of about 10 to 20 mm is preferably employed. This reinforced corrugated cardboard material is also used in the main portions of the lid 23 and the insertion end plate 22Y and is composed of two thick plates (liners) Rb and Rf, as shown in the enlarged view of the R portion in Fig. And two corrugated plates r1 and r2 are stacked with a partition plate r3 interposed therebetween. Of the two plates (liner) (Rb, Rf), the outer plate is the one facing the tube outer side, and the inner plate is the one facing the tube inner side.

14, 16, 18, and 19), dot-shaped portions are portions formed of reinforced corrugated cardboard material, and diagonal portions are formed of wood or wood-like material . In the second embodiment, a two-layer reinforced corrugated cardboard material is employed, but it is also possible to employ a three-layer reinforced corrugated cardboard material (for example, manufactured by TRI-WALL).

The corrugated cardboard hinge 25 cuts out the outer shell and the core from the reinforced corrugated cardboard material of the connecting portion connecting the base sideboard 22B and the guiding sideboard 22X to the planar sheath, Is folded in conformity with the boundary line between the base side plate 22B and the movable side plate 22X.

Specifically, the original plate of the reinforced corrugated cardboard material is cut to a predetermined width and length, and a planar (shearing I-shaped) sheath is formed on the boundary line between the base side board 22B and the side board 22X. This sheath is formed by forming a plate (Rb, Rf) and a corrugated plate (r1, r2) (see Fig. 14) constituting the reinforced corrugated cardboard material . The folding line portion is folded into a corrugated cardboard hinge 25 by folding the rest of the thick plate (inner plate) while bending it along the boundary line (hinge pivot axis) between the base side plate 22B and the movable side plate 22X.

As shown in Figs. 14 and 17, an inner frame plate 21 made of corrugated cardboard is formed at the opening end portions of the guiding type side plate 22X and the insertion end plate 22Y. The inner frame plate 21 is formed by folding back the reinforced corrugated board material in the V-grooves arranged in two rows.

When folding the reinforced corrugated cardboard material, one of the thick plates Rf and Rb of the corrugated cardboard layer is left and the other layer is formed with a V-groove using a rotating blade or the like, and only the other thick plate (liner) , And the slope of the V-groove makes the groove surfaces closely contact with each other. When the V-groove processing is performed so that the groove angles of the V-grooves are substantially 90 [deg.], Adjacent plates are folded almost vertically and bent. As another means for forming the V-groove, the corrugated board may be compressed into a V-shaped cross section by a press machine or the like.

Fig. 15 shows an expanded sheet of reinforced corrugated cardboard material for forming the base side plate 22B (outer wall portion) on the left side and the guiding type side plate 22X in Fig. 14 as an example.

A planar (corrugated cardboard hinge 25) having a planar shape (I-shaped in cross section) is formed between the base side plate 22B and the movable side plate 22X in the spreading sheet 20p, Two rows of V grooves (v1, v2) arranged in parallel between the inner frame plate 21 and the inner frame plate 21 are connected at an angle of almost 90 degrees. The inner sheet 21 is formed on the inner side of the tube body 22 by folding and bending the spread sheet 20p along these two rows of V grooves v1 and v2.

Further, between the V-grooves (v1, v2) of two rows, substantially the same gap is provided as the thickness of the spread sheet 20p. An intermediate plate 21m made of reinforced corrugated cardboard material shown in Fig. 14 is fitted in the gap portion. As a result, the folding width of the inner frame plate 21 becomes three times as large as the thickness of the spreading sheet 20p, and a wide surface of the opening of the pipe body 22 is secured.

By providing the inner frame plate 21 at the opening ends of the guard-type side plate 22X and the insertion end plate 22Y as described above, the strength of the tube body 22 can be greatly increased. Further, since the placement surface of the opening end of the pipe body 22 is secured to be equal to or larger than the thickness of the single reinforced corrugated cardboard material, the stability of the lid 23 is increased.

Of the plate members constituting the tube main body 22, the bottom plate 12A, the inner wall of the base side plate 22B, and the base end plate 12C are made of wood or ligneous material superior in strength to reinforced corrugated board material.

In this manner, the base portion of the tube body 22 is formed of a material having higher strength than the reinforced corrugated cardboard material, so that the load-bearing property and durability of the tube body 22 are ensured.

A lower inner plate 23s and an upper inner plate 23t made of wood or wood material are provided on the inner wall of the pipe main body 22 on the wall surfaces of the base side plate 22B and the end face of the movable side plate 22X. (See Fig. 12). Similarly, a bottom end face plate 24s and an upper end face plate 24t made of wood or wood material are provided on the wall surface of the end portion of the insertion end plate 22Y as the inside of the tube main body 22 (see Fig. 17).

By attaching these lower inner linings 23s and 24s and the upper inner linings 23t and 24t to the inside of the tube main body 22, the outer circumference of the base side plate 22B, the guiding type side plate 22X, The thickness of the end portion is increased, and the strength of the tube main body 22 can be increased.

The engaging grooves 16 and 16, the lower engaging projections 17 and the upper engaging projections 18 are likewise formed of a wood or wood material having a higher strength than the reinforcing corrugated cardboard material (see FIG. 18).

A cover portion 19b is provided above the engaging grooves 16 and 16 and an air gap 19a is provided above the upper engaging protrusion 18 respectively.

The engaging grooves 16 and 16 extend in the height direction of the end plate frame piece 27 provided at the left and right end portions of the insertion end plate 22Y. The end plate frame piece 27 is made of wood or ligneous material and is integrally adhered and fixed to both end portions of the insertion end plate 22Y made of reinforced corrugated cardboard. On the inner side of the tube of the end plate frame piece 27, the fixing portion 27f is extended (see Fig. 18), and the fixing portion 27f is fitted into the reinforced corrugated cardboard material so as not to be seen from outside the tube.

In addition, chamfering of a cross-sectional arc shape is applied to the corner portion of the end plate frame piece 27 on the outside of the pipe. Similarly, chamfering is applied to the corner portion of the lid 23 so that when the lid 23 is placed on the pipe body 22, the corner portions of the lid 23 extend in the height direction without a step. As a result, the corners of the tube main body 22 become rounded and finished with a design having a soft impression.

The lower engaging projections 17 are integrally formed on the front and rear end surfaces of the inner wall portion of the base side plate 22B in the range of their thickness.

The upper engaging projection 18 is integrally formed with the side plate frame piece 26 (see Figs. 14 and 16) as the front and rear end surfaces of the guiding type side plate 22X. The side plate frame piece 26 is made of wood or ligneous material and is fixed between the side plate 22X made of reinforced corrugated cardboard material and the inner frame plate 21. [ As shown in Fig. 18, the side plate frame piece 26 and the intermediate plate 21m are located on substantially the same plane.

As described above, the engaging grooves 16, 16, the lower engaging projections 17, and the upper engaging projections 18 are formed of wood or wood material having higher strength than the reinforcing corrugated cardboard material. Sufficient.

According to the pipe 20 of the second embodiment, in addition to the effects of the first embodiment, reinforced corrugated board material is adopted for a part of the plate material of the pipe body 22 and the lid 23, And the burning property at the time of make-up can be increased.

In the second embodiment, wood or woody material is used for the portion of the plate material constituting the pipe body 22 and the lid 23, where the strength is required, so that the durability of the entire pipe can be sufficiently secured. That is, by effectively combining the reinforced corrugated cardboard material with the wood or ligneous material, the durability of the pipe can be sufficiently secured, and the characteristics of the reinforced corrugated cardboard of light weight and combustibility can be utilized.

In addition, according to the pipe 20, since the corrugated cardboard hinge 25 is employed as the hinge for connecting the movable side plate 22X so as to be foldable with respect to the base sideboard 22B, the hinge hinge of metal or the like is unnecessary . The operation of mounting the hinge hinge becomes unnecessary. As a result, the production cost of the tube 20 can be suppressed.

In addition, since the inner side of the base side plate 22B and the inner side of the guiding type side plate 22X are flat by the corrugated cardboard inner plate (inner plate), the inside of the tube can be simply finished. The hinge portion does not become obstructive when entering or leaving tribute.

In the second embodiment, a configuration different from that of the first embodiment is adopted as the positioning means for pushing the insertion end plate 22Y.

As shown in Fig. 19, a stepped portion 28 is provided below the base end plate 12C. The stepped portion 28 is formed by setting the front and rear ends of the bottom plate 12A to a length that protrudes outward beyond the base end plate 12C.

A notch 29 is provided at the lower end of the insertion end plate 22Y. The notch 29 is formed by cutting the lower end plate 24s of the insertion end plate 22Y to a size substantially equal to the dimension of the step 28. [

When the insertion end plate 22Y is pushed in front of and behind the base end plate 12C, the notch 29 is mounted on the stepped portion 28 and the upper end of the insertion end plate 22Y is the same as the upper end of the movable side plate 12X Position. That is, the stepped portion 28 and the cutout portion 29 serve as positioning means for the insertion end plate 22Y.

With such a configuration, positioning of the insertion end plate 22Y can be easily performed simply by adjusting the height of the notch 29. [ The gap portion 19a may be wider than the cover portion 19b so that the cover portion 19b does not contact the upper engagement protrusion 18. [

In the second embodiment, a configuration different from that of the first embodiment is adopted for the locking means when the insertion end plate 22Y is pushed in as follows.

In the base end plate 12C, a lock hole h2 passes directly above the lower end plate 24s (see Fig. 19). The lock pin L2 is detachably inserted into the lock hole h2. When the lock pin L2 is inserted from the lock hole h2 into the upper portion of the lower end plate 24s, the lower end plate 24s is caught by the lock pin L2 and the upward movement of the insertion end plate 22Y is stopped . That is, the lock hole h2, the lock pin L2 and the lower end plate 24s serve as locking means for the insertion end plate 22Y.

A window unit (W) is provided at a position in front of the lid (23). The window unit W is equipped with a double-sided door, which can be seen through the inside of the tube by opening these doors.

As shown in Fig. 21, the tube main body 32 has a bottom plate 12A, a base side plate 22B and a base end plate 12C. The base side plates 22B and 22B are erected to face each other on the long side of the rectangular bottom plate 12A and the base end plates 12C and 12C are erected on the short side of the bottom plate 12A.

On the upper side of the base side plate 22B, a lower plate 32Xs and an upper plate 32Xt constituting a movable side plate are formed in an up-and-down manner. The upper and lower engaging projections 18 and the inner plate 23t of the tube main body 32 are vertically divided at the boundary between the bottom plate 32Xs and the top plate 32Xt (see FIG. 21).

A lower hinge 35s is provided between the base side plate 22B and the lower plate 32Xs and an upper hinge 35t is provided between the lower plate 32Xs and the upper plate 32Xt. The lower plate 32Xs and the upper plate 32Xt are folded in two steps in the left and right directions by the lower hinge 35s and the upper hinge 35t.

(The engaging groove 16, the lower engaging projection 17, and the lower engaging projection 17) are provided on the front and rear outer sides of the base side plate 22B and the movable side plates (the lower plate 32Xs and the upper plate 32Xt) And the upper engaging projection 18), the insertion end plates 22Y and 22Y are connected and aligned.

The outer wall portion of the base side plate 22B and the viscous side plates (the lower plate 32Xs and the upper plate 32Xt) of the plate members constituting the tube main body 32 have a multi-layer structure of a core member sandwiched between the outer plate and the inner plate And is integrally formed by a corrugated board material.

The lower hinge 35s cuts the inner plate and the core material into a planar shape (I-shaped in cross section), leaving the outer plate, of the reinforced corrugated board material of the connecting portion connecting the base side plate 22B and the lower plate 32Xs, And folds the rest of the shell plate in accordance with the boundary line between the base side plate 22B and the lower plate 32Xs.

The upper hinge 35t cuts the inner plate and the core material into a planar sheath while leaving the outer plate among the reinforced corrugated board materials of the connecting portion connecting the lower plate 32Xs and the upper plate 32Xt, 32Xs and the top plate 32Xt.

Specifically, the original plate of the reinforced corrugated cardboard material is cut into a predetermined width and length, and two planar sheaths are formed on the boundary lines of the base side plate 22B, the bottom plate 32Xs, and the top plate 32Xt. This sheath is formed by forming the other plate (outer plate) which is outside the pipe among the plate plates Rb and Rf and the corrugated plates r1 and r2 (see Fig. 14) constituting the reinforced corrugated plate material, . By bending the remaining portion of the thick plate (outside plate) in accordance with the boundary line of each plate, the folding line portion becomes the lower hinge 35s and the upper hinge 35t.

The vertical width of the bottom plate 32Xs is set to be substantially equal to the vertical width of the base side plate 22B and the vertical width of the top plate 32Xt is set to a length equal to or shorter than half the width of the bottom plate 12A . By setting the plate width in this manner, it becomes possible to fold the lower plate 32Xs and the upper plate 32Xt back along the outer surface of the tube main body 32 at the time of folding, which will be described later.

When the tube main body 32 is folded, the bottom plate 32Xs is folded back substantially 180 degrees from the standing posture indicated by the chain double-dashed line in Fig. 23A to be superimposed on the outside of the base side plate 22B. At this time, since the base side plate 22B and the bottom plate 32Xs have the same height dimension, the tip of the bottom plate 32Xs comes to the lowest position of the base side plate 22B.

Next, when the top plate 32Xt is folded 90 DEG to the left and right inward, it is overlapped with the bottom of the bottom plate 12A. As a result, as shown in Fig. 23 (B), the tube main body 32 is compactly folded with the top of the bottom plate 12A being open.

According to the pipe 30 of the third embodiment, since the guiding type side plates (the lower plate 32Xs and the upper plate 32Xt) are brought back to the outside of the pipe when the pipe body 32 is folded, State, and this space can be efficiently used as a storage space. 24, when the decorative lid 36 is turned upside down and placed in a space above the bottom plate 12A, the pipe body 32 (see Fig. 24) And the decorative lid 36 are housed in a compact form suppressing the height. Likewise, the insertion end plate 22Y, which is detached from the tube main body 32, can also be stored in the space on the bottom plate 12A.

In the structure of the pipe 30, since the outer side surfaces of the base side plate 22B and the movable side plates (the lower plate 32Xs and the upper plate 32Xt) are flat by the corrugated board surface (outside plate) So that the boundary of the light-shielding film can not be seen from the outside. As a result, in addition to the fact that there are few cut marks on the tube end face (insert end plate 22Y), it is possible to finish with a tube having excellent design properties with few cut marks on the tube side.

Also, in the structure of the pipe 30, since the corrugated board material is employed for the plate materials such as the base side plate 22B and the viscous side plates (the lower plate 32Xs and the upper plate 32Xt), as in the second embodiment, And the burning property at the time of make-up can be increased.

In addition, in the pipe 50, the engaging groove 16 can be formed in the thickness of the insert end plate 12Y, and the engaging groove 16 can be formed in the cross section of the movable side plate 52X The engaging projections 57 can be formed. This simplifies the manufacturing of the joints (engagement grooves 16 and engaging projections 57) between the guard-type side plate 52X and the insertion end plate 12Y, so that the strength of the seam can be sufficiently secured.

Although the prefabricated pipes according to the first to fifth embodiments have been described above, the embodiments of the present invention are not limited to these configurations, and various modifications and changes may be made.

[Modification: Locking means (1) of the insertion end plate]

In the first to fifth embodiments, although the lock hole and the lock pin are used as the locking means of the insertion end plate 12Y, a lock means formed of a leaf spring may be employed. In the modification shown in Fig. 32, the plate spring M1 is fixed to the outside of the tube of the base end plate 12C. The leaf spring M1 is inclined downward to the outside and is pushed from left to right in Fig. 32, and this inclined portion is bent to a position where it coincides with the plate surface of the base end plate 12C.

32A, when the insertion end plate 12Y is pushed in, the leaf spring M1 is pushed by the inner surface of the insertion end plate 22Y, and the lower end plate 24s is bent by the leaf spring M1 , The plate spring M1 returns to its original state. Then, the leaf spring M1 is engaged with the lower end plate 24s, and the upward movement of the insertion end plate 22Y is stopped.

[Modification: Locking means (2) of the insertion end plate]

As the locking means of the insertion end plate 22Y, a combination of a leaf spring and a slit-shaped lock groove may be employed. 33, the leaf spring M2 is fixed to the upper end surface of the lower end plate 24s, and the slit-shaped lock groove (not shown) cut in the horizontal direction on the front side (left side in FIG. 33) (K1).

33 (A), when the insertion end plate 22Y is pushed in, the tip end of the leaf spring M2 is moved downward inside the tube of the insertion end plate 22Y, It returns to its original state after being inserted. As a result, the leading end of the leaf spring M2 is caught by the base end plate 12C, and the upward movement of the insertion end plate 22Y is stopped.

[Modification: Locking means (3) of the insertion end plate]

As the locking means of the insertion end plate 22Y, a combination of a leaf spring and a comb-shaped lock groove may be employed. 34, the leaf spring M2 is fixed to the upper end surface of the lower end plate 24s and the lock groove K2 formed in the front side of the base end plate 12C (left side in Fig. 33) .

34 (A), when the insertion end plate 22Y is pushed in, the leading end of the plate spring M2 is bent at the inner side of the insertion end plate 22Y to be engaged with a portion of the lock groove K2 And moves downward. As a result, the tip end of the leaf spring M2 is engaged with the base end plate 12C at the portion where the groove of the lock groove K2 is formed, and the upward movement of the insertion end plate 22Y is stopped.

In this configuration, since the lock position of the insert end plate 22Y is adjusted by the lock groove K2, the work for machining the lock means is facilitated.

[Other Modifications]

As a positioning means of the insertion end plate 22Y, a stopper mounted on the base end plate 12C may be provided inside the tube of the insertion end plate 22Y. In the example shown in Fig. 33, a stopper Q made of a block piece is provided as an positioning means on the inner side surface in the front-rear direction of the insertion end plate 22Y. When the stopper Q is mounted on the base end plate 12C when the insertion end plate 22Y is pushed in, the upper end of the insertion end plate 22Y coincides with the upper end of the movable side plate. Thus, the insertion position of the insertion end plate 22Y can be precisely positioned.

In the second to fourth embodiments, a cloth or a film sheet may be adhered to the surface of the pipe body to make it difficult to show a folded mark of the corrugated cardboard hinge on the pipe surface. According to such a configuration, the outer shape of the tube body is further improved, and the quality of the tube can be improved.

In the fifth embodiment, the hinge band 53 is made of a long timber, but a short block type timber may be used. In this case, the length of the hinge band 53 is set so that the hinge hinge 15 can be mounted, and the number of the hinge bands 53 is used in accordance with the number of the hinge hinge 15. [

With this hinge band 53, the size of the hinge band 53 becomes extremely compact, so that the space in the tube can be made wider than in the first to fourth embodiments. Further, as the hinge band 53 becomes smaller, the weight of the pipe can be reduced.

Further, since the material of the hinge band 53 is reduced, manufacturing cost of the tube can be suppressed.

It is also possible to form the hinge band 53 and the base side plate 22B integrally with the reinforced corrugated cardboard material and replace the hinge hinge 15 with the corrugated cardboard hinge.
