[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shaft of a hanging shaft.
[0002]
[Prior art]
Conventionally, when strip-like works such as tapestry, patchwork, embroidery, lace knitted fabric, and dyed goods are unfolded and displayed, a shaft is attached to the top and bottom edges of the work, and a hanging string is attached to the shaft at the top edge of the work In addition to hanging, the work may be spread and displayed in the form of a shaft attached to the top and bottom edges.
[0003]
[Problems to be solved by the invention]
When a shaft is attached to a work by such an exhibition method, conventionally, as shown in FIG. 8, the upper and lower edges 3a, 3a of the work 3 are folded back to form the cylindrical portions 3b, 3b. Inserting the shafts 1 and 1 (for example, “FIG. 2” in Japanese Patent Laid-Open No. 2000-139650), or as shown in FIG. The screw is clamped and fixed integrally with fasteners 4 and 4 such as screws, or bonded with an adhesive.
[0004]
However, the method of forming the cylindrical portions at the upper and lower edges of the former work is not suitable as a display means because the outline shape of the work is impaired when the strip itself as described above is a work.
[0005]
On the other hand, in the latter case, the split pieces 1a and 1b which are divided into two parts of the shaft 1 have the same shape. Therefore, if not careful, the fastening fasteners 4 and 4 are attached to the front side of the work 3 as shown in the illustrated example. Appearance was inconvenient and the fasteners 4 and 4 such as screws penetrated the edge 3a portion of the work 3 and were damaged.
[0006]
Further, the lower surface portion 2a of the divided surface 2 of the shaft 1 may be seen from the front lower side depending on the display height of the work 3, and there is a problem that the display mode is not preferable.
[0007]
On the other hand, the method of directly bonding the work to the shaft 1 instead of the fasteners 4 and 4 is not inconvenient as using the fastener, but it is damaged when the work is peeled off from the shaft after the exhibition. There was a problem that could be damaged.
[0008]
The present invention solves the above problems, can be easily attached to the work, can be arbitrarily detached without damaging or soiling the work, and can be displayed without any loss of the aesthetic value of the work. It was made for the purpose of providing trees.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problem, the shaft of the hanging shaft according to claim 1 is vertically divided in the axial direction by two divided surfaces where the shaft is bent and intersected at the center of the cross section orthogonal to the axis. When the divided piece on the side where the crossing angle formed by the surface becomes smaller is the first divided piece and the other side is the second divided piece, from the outer surface of the first divided piece toward any one of the divided surfaces A through hole is provided, and a screw hole that is coaxial with the through hole is provided on a corresponding dividing surface of the second divided piece, and the first and second divided pieces are overlapped, and the side without the screw hole is provided. The sheet-shaped exhibit is sandwiched between the divided pieces by clamping the sheet-shaped exhibit between the divided surfaces and tightening the screw member inserted through the through hole. It is.
[0010]
Therefore, according to the shaft of the hanging shaft of claim 1, if the surface for fastening the fastener for fastening the first divided piece and the second divided piece is the back side of the exhibit, the fastener is the axle In addition, the dividing plane is also shifted from the vertically lower side to the back side, so that the dividing line is difficult to see from the front side of the work, and the effect of the divided structure of the shafts on the appearance of the work is eliminated.
[0011]
In particular, when decoration is applied to the front side of the shaft itself, the divided surface is shifted from the front side to the back side, so that the appearance of the decoration viewed from the front side is not affected.
The shaft of the hanging shaft according to claim 2 is the shaft of the hanging shaft according to claim 1, wherein a protruding portion having elasticity is provided on a vertical dividing surface, and the display is elastically held by the protruding portion. It is made like that.
[0012]
Therefore, the fixing is ensured even for a thin sheet-like exhibit.
The shaft of the hanging shaft according to claim 3 is a shaft-like reinforcing member of the hanging shaft according to claim 1 or 2, which is a sheet-like reinforcing member having a waist shape and capable of being engaged with an edge of the work. It is provided with a mounting aid that is inserted into the split surface while being engaged with the edge.
[0013]
According to this invention, even if the work has no waist such as a cloth, the edge is straightened by engaging the attachment auxiliary tool with the edge, and the attachment to the shaft is facilitated.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described.
Embodiment 1
1 is an exploded perspective view of a shaft wood of a hanging shaft according to Embodiment 1 of the present invention, FIG. 2 is an enlarged side view of the shaft wood, and FIG. 3 is a sectional view taken along line AA in FIG.
[0015]
In FIG. 1 to FIG. 3, a shaft wood 10 of a hanging shaft is a rod-shaped body made of wood or synthetic resin whose cross section perpendicular to the axis is circular, and is a radially divided surface 12 bent at the center 11 of the main body cross section, 13 is divided vertically in the axial direction. Of the crossing angles θ and α (FIG. 2) formed by the split surfaces 12 and 13, the side of the crossing angle θ that is smaller is the first split piece 10a, and the other side is the first split piece 10a. When the second divided piece 10b is used, a through hole 15 is formed as shown in FIG. 3 from the outer surface 14 of the first divided piece 10a to the divided surface 13, and the screw hole is coaxial with the through hole 15. 16 is provided on the corresponding dividing surface 13 of the second divided piece 10b, and the first and second divided pieces 10a and 10b are formed into the cylindrical shaft 10 by screwing screws 19 into the screw holes 16 from the through holes 15. To be assembled.
[0016]
The crossing angle θ is greater than 90 ° and smaller than 180 °, preferably around 135 ° ± 20 °. The reason is that if the angle is smaller than 110 °, the dividing surface 13 is easily visible from the front side, and if it is larger than 155 degrees, the clamping force when the work is sandwiched between the dividing surfaces 12 and 12 is reduced when tightening with screws. In the case of a thin work, the clamping force is not sufficient.
[0017]
The screw hole 16 provided in the dividing surface 13 is a cylindrical member having a female screw hole or a nut 17 having a thread 17a on the outer surface in the hole 16a for the screw hole 16 when the shaft 10 is made of wood. (Not shown) is mounted by driving into the hole 16a for the screw hole 16, and when the main body 10 is made of synthetic resin, the screw hole 16 is directly formed in the main body or the nut 17 is embedded similarly to the above. The structure is made.
[0018]
In the illustrated example, the tip end of the nut 17 is slightly protruded from the dividing surface 13, and the protruding portion 17b can be fitted into the through hole 15 of the first divided piece, and is used as an alignment protruding portion.
[0019]
2 and 3, a member denoted by reference numeral 20 indicates a protrusion made of rubber-like elasticity, and is used for elastically holding the work. As shown in FIG. The split piece 10a is provided on the surface of the split surface 12 over almost the entire length of the shaft 10 in the length direction. As a material having rubbery elasticity, a protrusion of synthetic resin such as urethane, urethane foam, and polystyrene foam is preferably used. Further, the surface of the ridge 20 may be provided with fine irregularities as shown in the figure so as to increase the supporting force. Moreover, these protrusions 20 are provided on either one side of the divided surface 12 on the side where the screw holes of the first and second divided pieces are not provided.
[0020]
Next, the usage state of the shaft of the hanging shaft according to the first embodiment will be described.
As shown in FIG. 1, the second divided piece 10b of the shaft 10 is placed on the lower end 3a of the sheet-like work 3 such as the tapestry or the patchwork described above on the front side of the work 3, and the first divided piece. 10a is arranged on the back side, the work is sandwiched between the split surfaces 12 and 12 on the side without the screw hole, the screw 19 is inserted from the through hole 15 opened on the work back side of the shaft 10, and the second The divided pieces 10a and 10b are fastened and fixed by screwing into the screw holes 16 of the divided pieces 10b.
[0021]
At this time, as shown in FIG. 3, the screwing direction is perpendicular to the dividing surface 13, but with respect to the other dividing surface 12, the screwing direction is inclined with an inclination angle (θ−90 °). The clamping force is also exerted in the vertical direction, and the work 3 is fixed to the shaft 10.
[0022]
Similarly, the shaft 10 is attached to the upper edge of the work, and the hanging string 20 is attached to the upper edge shaft 10 as shown in FIG.
In addition, as shown in FIGS. 2-4, when the protrusion 18 which has elasticity is provided in the division surface 12, a work can be clamped more reliably.
[0023]
At this time, the split surface 13 into which the screw 19 is screwed with respect to the vertical split surface 12 of the shaft 10 is shifted from the vertically lower side of the shaft 10 to the rear side, so that it cannot be seen from the front side. The screwed screw 19 is also hidden behind the shaft 10 and cannot be seen.
[0024]
Furthermore, since the second divided piece 10b exists on the front side of the shaft 10 and the surface of the second divided piece 10b extends from the lower surface of the shaft to the back side, the divided surface is from the front side of the work. In addition, even if decoration such as sculpture is applied to the front surface of the shaft 10, it does not appear to be divided by the dividing surface 13 from the front side. Therefore, it can be set as an appropriate display mode.
Embodiment 2
FIG. 6 is an exploded perspective view of a shaft tree of the hanging shaft according to the second embodiment.
[0025]
Compared to the shaft of the first embodiment, the shaft of the second embodiment is the same as the shaft of the first embodiment except that it has a mounting aid 21 attached to the lower edge of the work. Description is omitted, and only different parts are described.
[0026]
In the shaft 1 of the hanging shaft of the second embodiment, the attachment aid 21 is a thin sheet-like body with a waist, for example, a belt-like plastic plate with a waist that is folded in two along the center line in the width direction. It is configured to be inserted into the vertical dividing surface 12 of the shaft 1 while being sandwiched between the edges 3a and engaged in this manner.
[0027]
The mounting aid 21 may be formed with irregularities 21a to the extent that it does not damage the work so as to securely engage the work 3, and in this case, it is engaged with the split surface of the shaft. In order to improve the properties, it is desirable that the irregularities 21a appear on the outer surface.
[0028]
Before attaching the work 3 to the shaft 1, the attachment assisting tool 21 is first sandwiched between the edges 3 a of the work 3 and engaged using elasticity, and then attached to the shaft 1 as shown in FIG. 7. .
[0029]
In this case, if the work is curled, or if it is a work that does not have a waist and is not easily stretched in a straight line, it can be easily attached to the shaft 10 if it is attached in advance.
[0030]
【The invention's effect】
As described above, the hanging shaft for the hanging shaft according to the present invention is a divided surface obtained by dividing the shaft by a divided surface that is bent at the central portion and shifting the work sandwiched between the vertically divided surfaces to the back side of the shaft. Since the fastening part provided on the side is fastened, the split surface on the side where the fastening part or the work is not sandwiched is not visible from the front side of the shaft, and the appearance at the time of display is very good.
[0031]
Also, when the work is attached to the shaft, the bent line of the bent part is along the central axis of the shaft, so it is easier to align the edges if the work is placed so that it is aligned with the center line, and fastening is also possible It has an effect that can be easily performed.
[0032]
In addition, when decoration is applied to the surface of the shaft, even if the decoration is discontinuous due to the split surface on the lower surface of the shaft, the part is hidden on the back side of the shaft, so the appearance from the front side is good, etc. It has the effect of.
[0033]
Moreover, if the protrusion which has rubber-like elasticity is formed in the division surface which pinches | interposes a work, the mounting power of a work will improve further.
Then, by combining an auxiliary tool that can be engaged with the edge of the work, even a cloth-like work without a waist can be easily attached.
