Description

The present invention relates to a partition, a method for manufacturing a partition face material, and a method for manufacturing a partition, which can be used to partition an office space or the like.

Conventionally, as a partition used for partitioning an office space, a panel type as shown in Patent Document 1 is generally used. The partition panel A shown in FIG. 1 of this document constitutes a panel main body 1 which is a structure by combining a rigid vertical frame 11, a horizontal frame 12, a steel plate 13, an appropriate reinforcing member, and the like, and the panel main body 1 Is supported by the adjuster 14, and the decorative material 15 is adhered to both sides of the panel body 1, and the cap tree 16 is arranged at the upper end and the skirting board 17 is arranged at the lower end.

When developing variations of such a partition panel A, it is customary to diversify by changing the size, the material and color of the decorative material 15, and the pattern.

JP-A-2007-107319

However, since it is necessary to use different parts for each size, shape, and pattern of such a structure, it is costly to develop variations and the design tends to be uniform.

Therefore, the present invention has focused on a mesh-like face material called an expanded metal. As shown in FIG. 15A, this type of face material is a metal plate in which a wavy upper blade d descends from above with respect to a linear lower blade c while feeding out the metal plate a by a roller b. A region having a constant width of a is cut up in a wavy shape as shown in FIG. 15 (b), and when the upper blade d rises next, the metal plate a is fed in the feed direction (X direction) by a constant width and the upper blade d Moves to a position shifted by a predetermined distance in the direction (Y direction) orthogonal to the feed direction (X direction), and the wavy upper blade d descends from above with respect to the linear lower blade c again. As shown in FIG. 15 (c), a region of a constant width of the metal plate a is cut up in a wavy shape, and when the upper blade d is further raised, the metal plate a is fed by a constant width in the feed direction (X direction) and the upper blade is fed. d Moves to a position that is out of phase by a predetermined distance in the −Y direction, which is orthogonal to the feed direction (X direction) (that is, returns to the original position), and again corrugates above the linear lower blade c. By repeating the operation of cutting the region of a certain width of the metal plate a in a wavy shape by descending from above, the blade d with respect to the direction (Z direction) orthogonal to the feed direction (X direction) of the metal plate a. Rhombus-shaped meshes are sequentially formed in a state of being alternately out of phase.

If such an expanded metal is used as a partition for an office or the like, which is a completely different field from the conventional one, differences in size and shape can be dealt with simply by changing the cut area of the expanded metal. However, since the shape of the mesh is constant simply by using such an expanded metal, in order to produce an expanded metal having various shapes and patterns, the corrugated shape of the upper blade may be changed or a metal plate may be used. It is necessary to change the feed rate of the upper blade and the phase amount of the upper blade. And, in order to change the wave shape, it is necessary to prepare an upper blade for each specification, and in order to change the control amount such as feed rate and phase amount, the control becomes complicated and still planned. It can only be a mesh-like shape or pattern.

The present invention is based on an idea different from that of expanded metal, and is capable of generating various unexpected shapes and patterns from the same material with a simple operation. Partitions and partitions using new face materials. The purpose is to realize a method for manufacturing face materials and a method for manufacturing partitions.

The present invention has taken the following measures in order to achieve such an object.

That is, the partition according to the first aspect of the present invention includes a plurality of lines extending vertically or horizontally and a connecting portion for connecting adjacent lines, and the connecting portion is shorter than the wires. , The connection part with the line adjacent to one side and the connection part with the line adjacent to the other side are provided at positions that are out of phase, and between the adjacent lines, at least other than the end of the line. A face material in which a hole is formed by a pair of wires arranged adjacently at a site and a pair of connecting portions, and an opening recess is formed at an end of the wires in which at least a pair of wires arranged adjacent to each other are not connected. It is characterized in that the streaks constituting the face material have an irregular wavy line shape.
Further, the partition according to the second aspect of the present invention includes a plurality of lines extending vertically or horizontally and a connecting portion for connecting adjacent wires, and the connecting portion is shorter than the wires. , The connection part with the line adjacent to one side and the connection part with the line adjacent to the other side are provided at positions that are out of phase, and between the adjacent lines, at least other than the end of the line. A face material in which a hole is formed by a pair of wires arranged adjacently at a site and a pair of connecting portions, and an opening recess is formed at an end of the wires in which at least a pair of wires arranged adjacent to each other are not connected. The width of the streaks constituting the face material is substantially uniform except for a part, and is characterized to be different in some parts.

In both the first aspect and the second aspect, a partition having an unprecedented appearance is formed to partition the space so that the space is seamlessly connected by the streaks and the holes. Moreover, since the gap between the strips can be extended due to the presence of the opening recess at the end of the strip, the place where tension is applied to the face material along the adjacent direction is between the adjacent strip and the pair of connecting portions. Since the hole portion closed by is widened as a matter of course, an unexpected shape with a broken uniformity is likely to occur.
In particular, according to the second aspect, the width of the streaks constituting the face material is substantially uniform except for a part, and is configured to be different in a part, so that the shape of the hole can be controlled to some extent. Can be.

In order to cause the deformation of the hole without difficulty, each line of the face material extends diagonally toward the connection part with the line adjacent to one side, and extends to the connection part with the line adjacent to the other side. It is desirable that it extends diagonally with a reverse slope.

In order to avoid the shape and pattern from becoming extremely unstable visually, the pair of adjacent lines of the face material should have a separation distance at the connection portion smaller than the separation distance before and after the connection portion. It is desirable that the slope extends over the entire length while alternating the inclination direction.

As a structure that can be expected to have an unexpected shape or pattern, there is a wavy line shape in which the width of the streaks constituting the face material is almost uniform, and the wavy line shape differs depending on the location. Be done.

Through the above structure, a partition in which a plurality of shapes or non-uniform shapes are mixed is formed in the hole portion.

Mainly, when it is desired to cause the deformation of the hole portion in the direction orthogonal to the direction in which the streak extends, the hole portion of the face material is the separation distance between the connection portions in the direction in which the streak extends rather than the separation distance between the striae. It is desirable to keep the length longer.

In order to secure a certain amount of deformation and regularity in the deformation of the holes, every other hole and an opening recess are formed between the adjacent lines at the ends of the lines constituting the face material. It is desirable that it is done.

In order to homogenize the changes that occur in the process to some extent and to make it easier to extend, opening recesses are formed between the adjacent lines at the ends of the lines constituting the face material. Is desirable.

Even if the face material itself has flexibility, in order to enable stable installation and assembly as a partition, the face material is housed in a rectangular frame connecting a vertical frame and a horizontal frame to partition. It is desirable to configure.

Further, in the method for manufacturing a partition face material according to the present invention, a punched row in which punched portions are intermittently continuous vertically or horizontally is adjacent to a plate material in a state where the punched portions are out of phase, and the ends of the punched rows are adjacent to each other. At least a part of the punched portion of the portion is provided in an open state, and the punched portion is extended by pulling a plate material along the adjacent direction thereof, so that the punched portion is adjacent to a plurality of lines extending vertically or horizontally in the adjacent state. A connection portion for connecting the wires is formed, the connection portion is shorter than the wire, and the connection portion with the wire adjacent to one side and the connection portion with the wire adjacent to the other side have a phase difference. In a displaced state, a hole is formed between a pair of strands and a pair of connecting portions arranged adjacent to each other at least at a portion other than the end of the strand, and at least at the end of the strand. It is characterized in that it constitutes a face material in which an opening recess in which a pair of adjacent wires are not connected is formed.

By using such a manufacturing method, it is possible to easily manufacture various partition face materials that are not the same as the two by simply pulling the plate material with a stretcher after punching the punched part on the plate material with a press machine. Can be done.

In this case, a punched hole is suitable as a punched portion for manufacturing a face material having a large elongation rate.

On the contrary, if it is intended to manufacture a face material having a small elongation rate, it is desirable to make the punched portion a slit.

Further, in the method for manufacturing a partition according to the present invention, the partition face material manufactured by the above-mentioned method for manufacturing a partition face material is left and right having a groove for closely accommodating the vertical edge of the face material at least on the inner surface side. It is desirable to mount the upper and lower ends of the vertical frame in a rectangular frame connected by a horizontal frame.

Since the present invention has the configuration described above, it is possible to easily generate various unexpected shapes and patterns from the same material by a simple operation. A method for producing a material and a method for producing a partition can be provided.

Hereinafter, the first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the partition P of this embodiment has a plurality of face members 3A and 3B in a rectangular frame body 1 composed of left and right vertical frames 11, upper and lower horizontal frames 12, 13 and intermediate frames 14. It is configured by accommodating 3C. FIG. 2 shows the face material 2 used here.

Hereinafter, a step of attaching the face materials 3A to 3C to the frame body 1 and finishing the partition P will be described after explaining the specific manufacturing method and structure of the face material 2.

First, as shown in FIG. 3, a metal plate material 2 such as a steel steel plate is applied to a press machine B. The press machine B carries out a step of forming a punching portion 21 formed of a rectangular punching hole in the metal plate material 2 by the head portion B1 while feeding the metal plate material 2 at a predetermined pitch.

The head portion B1 of the press machine B is provided with a plurality of blades Ba for forming the rectangular punching 21 portion at a predetermined pitch in a direction (Y direction) orthogonal to the feed direction (X direction). When the head portion B1 moves up and down and finishes the pressing operation, the metal plate material 2 is fed by a constant width in the X direction, and the head portion B1 moves to a position shifted in phase by a predetermined distance in the longitudinal direction (Y direction). Then, at that position, the head portion B1 moves up and down again to finish the pressing operation, the metal plate material 2 is fed by a certain width, and this time, the head B1 is out of phase by a predetermined distance in the direction opposite to the above (−Y direction). The head portion B1 moves up and down again at the position (that is, the initial position), and the head portion B1 moves up and down again to perform the pressing operation. By repeating the above operation, the punched portion 21 is formed on the metal plate material 2. If the head portion B1 of the press machine B is large, a plurality of rows of blades that are alternately out of phase are provided, and the plurality of rows are pressed together so that the phase of the head portion B1 is not changed when the metal plate material 2 is fed. can do. The punched portion 21 is not limited to a rectangular shape, and may have an appropriate shape such as an oval shape.

As a result, the rows 2x of the punched portions 21 are formed on the metal plate material 2 in a state of being alternately out of phase in the direction (Y direction) orthogonal to the feed direction (X direction). In this embodiment, the side edge 2a in the direction (Y direction) orthogonal to the feed direction (X direction) is punched or punched so that the portion where the punched portion 21 is closed and the portion where the punched portion 21 is opened are alternately formed. After that, the face material 2 is cut.

Then, the metal plate material 2 is hung on the extender C shown in FIG. 4 to extend it. For example, when the grip portion 2b1 provided on the edge 2b of the metal plate 2 in the feed direction (X direction) is held by the chuck C1 and relatively moved between the chucks C1 and C1 in the separation direction, the edge 2b of the metal plate 2 is moved. The pulling force is sequentially transmitted from the center toward the center, and the entire metal plate 2 is extended as a whole.

At this time, the tensile force does not act evenly on all the parts, and the tensile force acting on the center far from the chuck C1 is weaker than the edge 2b near the chuck C1, so that the metal plate 2 as a whole Where it grows is a matter of course. Therefore, the punched portion 21 shown in FIG. 4 does not become a homogeneous hole portion 31 as shown in FIG. 5, and the punched portion 21 appropriately expands in each portion and has a different shape depending on the location as shown in FIG. It becomes part 31.

Here, aside from the extension rate, since the basic principle of forming the hole portion 31 is the same, the characteristics of the hole portion 31 generated will be described with reference to FIG. When the feed direction (X direction) is the vertical direction and the direction orthogonal to this (Y direction) is the horizontal direction, the line 32 extending in the horizontal direction (Y direction) is a line adjacent to both sides in the vertical direction (X direction). Since the strips 32'and 32' are connected alternately and a pulling force acts through the connected portions, the strip 32 is deformed into a wavy shape while the width W remains almost uniform, and is deformed into a wavy direction (X). In a state of being adjacent to each other (direction) and extending in the lateral direction (Y direction) between a plurality of lines 32-32'(between 32-32'), these adjacent lines 32-32' are adjacent to each other (32-32'. Connection portions 33 ′ and 33 ″ are formed to connect (to each other). Since the punched portion 21 shown in FIG. 3 is horizontally long, the connecting portion 33'(33') is larger than the lateral (Y direction) distance dy between the connecting portions 33'and 33'(between 33' and 33'). The distance dx in the vertical direction (X direction) in ´) is shorter. Further, when focusing on an arbitrary line (for example, 32), the connection portion 33'with the line 32'adjacent to one side of the upstream or downstream of the feed direction (X direction) and the line adjacent to the other side. The connection portion 33 ″ with 32 ″ is provided at a position where the phase is shifted by 1/2 pitch. Further, between adjacent lines, for example, 32-32', holes are formed in a pair of lines 32, 32'and a pair of connecting parts 33', 33'arranged adjacent to each other at a portion other than the end of the line 32. The holes 31 and the opening recesses 31x are formed by forming the portions 31 and forming an opening recess 31x in which at least a pair of wires 32, 32 ″ arranged adjacent to each other at the end of the line 32 are not connected. It is provided alternately in the X direction at the side end portion (see FIG. 4) of the line 32 in the lateral direction (Y direction).

Further, when viewed with reference to the wire 32, a hole located between the connection portion 33 ′ with the wire 32 ″ on one side and the connection portion 33 ″ -33 ″ with the wire 32 ″ on the other side. Since the center of the portion 31 is pulled, the streak 32 extends diagonally toward the connection portion 32'with the streak 32'adjacent to one side, and with the streak 32'adjacent to the other side. It is in a state of extending diagonally with a reverse inclination toward the connection portion 32 ″.

From a different point of view, the pair of adjacent lines, for example 32 and 32', alternate in the inclination direction over the entire length so that the separation distance dx at the connection portion 33'is smaller than the separation distance dx'before and after the separation distance dx. It will be in a state of being extended while changing.

Here, the difference from the expanded metal will be described. In the case of expanded metal, as shown in FIG. 15, the wavy upper blade d alternately changes the phase with respect to the linear lower blade c and descends from above to form a region of a constant width of the metal plate a. By repeating the operation of cutting up in a wavy shape, diamond-shaped meshes are sequentially formed in a state of being alternately out of phase with respect to the feeding direction of the metal plate.

That is, the face material 3 according to the present embodiment is fed from the X direction orthogonal to the punching direction (Z direction) and is fed out in the same X direction also orthogonal to the punching direction (Z direction), whereas the expanded metal Is sent from the X direction orthogonal to the punching direction (Z direction) of the metal plate a, and the metal plate a is fed out in the punching direction (Z direction). Therefore, the mesh is composed of a surface parallel to the initial metal plate a and a surface orthogonal to the initial metal plate a. That is, when the metal plate a after punching is pulled in the surface direction, the direction in which the pulling force acts propagates in a complicated manner.

On the other hand, according to the present embodiment, all the tensile forces of the metal plate material 2 in the surface direction act on the punched portion 21 under the same conditions, so that the progress is effectively triggered.

In this way, when the face material 3 is formed, the portion that has become the grip portion 2b1 is cut off, and this is incorporated into the frame body 1 to create the partition P. Of course, the portion that has become the grip portion 2b1 may be sandwiched between the frame bodies 1 so as not to come off. The partition P in FIG. 1 uses three face materials 3A, 3B, and 3C, and the face materials are only part of the openings OP1 to OP3 (see FIG. 6) into which these face materials 3A, 3B, and 3C are fitted. (For example, a mode in which 3B is fitted and the remaining portion has an open opening (for example, openings OP1 and OP3) is also possible.

7 to 12 are enlarged views of parts A to F in FIG. 1. As shown in FIG. 8, the vertical frame 11 has an inward channel material 11a having a groove 11a1 for tightly accommodating the vertical edge 3a of the face material 3 on the inner surface side, and is attached to the base material 11x. The upper frame 12 shown and the lower frame 13 shown in FIG. 11 have downward or upward channel materials 12a, 13a having recesses 12a1, 13a1 for accommodating the horizontal edge 3b of the face material 3 on the inner surface side, and the downward or upward channel materials 12a, 13a are attached to the base materials 12x, 13x. The intermediate frame 14 shown in FIGS. 9 and 10 is based on an upward channel material 14a and a downward channel material 14b having recesses 14a1 and 14b1 accommodating the horizontal edge sides 3b and 3a of the face material 3 on both the upper and lower surfaces. It is attached to the upper and lower surfaces of 14x, and after accommodating face materials 3A to 3C in the horizontal frame 12 and intermediate frame 14 of each opening OP1 to OP3 by the so-called kendon method, a vertical frame common to each face material 3A to 3C. 11 and 11 are fitted from the left and right to finish the partition P.

As described above, the partition P of the present embodiment connects a plurality of lines 32, 32 ′, 32 ″ extending in the lateral direction and adjacent lines 32, 32 ′ (32, 32 ″). The connecting portion 33 ″ (33 ″) is provided, and the connecting portion 33 ″ (33 ″) is shorter than the wires 32, 32 ′, 32 ″. The connection portion 33 ′ with the line 32 ′ adjacent to one side and the connection portion 33 ″ with the wire 32 ″ adjacent to the other side along the vertical direction (X direction) of Provided and adjacent to the adjacent lines 32, 32'(between 32, 32') at least at a portion other than the end 3a in the lateral direction (Y direction) of the lines 32, 32', 32'. A hole 31 was formed by a pair of arranged wires 32, 32 ′ (32, 32 ″) and a pair of connecting portions 33 ′ (33 ″), and was arranged at least adjacent to the end of the wire 32. A face material 3 having an opening recess in which the pair of wires 32 and 32 ″ are not connected is used.

With this configuration, it is possible to form a partition P having an unprecedented appearance that partitions the space so that the space is seamlessly connected by the line 32 and the hole 31. Moreover, since the opening recess 31x exists at the end 3a of the wires 32 and 32 ″, the space between the wires 32 and 32 ″ can be extended, so that tension is applied to the face material 3 along the adjacent direction (X direction). Is a hole closed between adjacent lines 32, 32'(32, 32') and a pair of connecting portions 33', 33'(between 33', 33'). Since the portion 31 ′ (31 ″) spreads as a matter of course, an unexpected shape with a broken uniformity is likely to occur.

Specifically, the streaks of the face material 3, for example 32, extend diagonally toward the connecting portion 33'with the striae 32'adjacent to one side, and the streaks 32'adjacent to the other side. Since it extends diagonally with a reverse inclination toward the connecting portion 33 ″, the angle extending toward the connecting portion 33 ′ with the line 32 ″ adjacent to one side and the angle extending toward the connecting portion 33 ″ are reasonably changed, and the other side is adjacent to the connecting portion 33 ″. Since the hole portion 31 expands by the sum of the reasonable changes in the angle extending in the opposite direction toward the connecting portion 33 ″ with the line 32 ″, the hole portion 31 is likely to be deformed.

Further, the pair of adjacent lines of the face material 3, for example, 32 and 32', alternately incline directions over the entire length so that the separation distance dx at the connecting portion 33'is smaller than the separation distance dx'before and after the separation distance dx. It extends while changing, and the separation distance dx between the lines 32 and 32'before and after the connection portion 33'changes while maintaining continuity while alternately changing the inclination direction, so that the distance is uneven. However, the continuity is maintained, and it is possible to avoid the shape and pattern from becoming extremely unstable visually.

The width W of the streaks 32 constituting the face material 3 has a wavy line shape having a substantially uniform shape, and it is not known where the deformation of the hole 31 occurs when tension is applied to the face material 3, so FIG. As shown, it is possible to increase the probability that a shape or pattern having a different wavy line shape will occur.

That is, with such a structure, a partition in which a plurality of shapes or non-uniform shapes are mixed can be formed in the hole portion 31 of the face material 3.

Further, in the hole portion 31 of the face material 3, the separation distance dy between the connecting portions 33'and 33'in the direction in which the wires 32 and 32'extend is longer than the separation distance dx between the wires 32 and 32'. Therefore, the hole portion 21 can be easily deformed in the direction (X direction) orthogonal to the lateral direction (Y direction) in which the lines 32 and 32'extend.

Further, in the side end portions 3a of the wires 32, 32 ′, 32 ″ constituting the face material 3, the hole portion 31 and the opening recess are formed between the adjacent wires 32, 32 ″ (between 32 and 32 ″). Since 31x is formed and the holes are alternately provided in the X direction, the hole 31 is difficult to expand, the opening recess 31x is easy to expand, and the deformation of the hole 31 and the opening recess 31 is easy to give a certain amount of deformation and regularity. It becomes.

Since the face material 3 is housed in the rectangular frame 1 connecting the vertical frame 11, the horizontal frames 12, 13 and the intermediate frame 14, even if the face material 3 itself has flexibility, the partition P Stable installation and assembly as a rectangle is possible.

Then, as a method for manufacturing such a partition face material 3, a state in which the punched rows 2x in which the punched portions 21 are intermittently continuous in the lateral direction (Y direction) with respect to the metal plate material 2 are out of phase with each other. At least a part of the punched portion 21 at the end of the punched row 2x is provided in an open state, and the punched portion 21 is extended by pulling the plate material 2 along the adjacent direction (X direction) to be adjacent. Connecting portion 33'(33') connecting a plurality of wires 32, 32', 32'" extending in the lateral direction (Y direction) and adjacent wires 32, 32'together (31, 31'") in the state. ''), And the connecting part 33 is shorter than the wire 32, and the connecting part 33 ′ with the wire 32 ′ adjacent to one side when viewed from the wire 32 and the wire 32 ″ adjacent to the other side. The connection portion 33 ″ with and is in a state of being out of phase, and a pair of streaks 32 arranged adjacent to each other at least at a portion other than the end portion of the streak 32 between adjacent striae, for example, 32 and 32 ′. , 32 ′ and a pair of connecting portions 33 ′, 33 ″ form a hole portion 31, and an opening recess 31x in which the wires 32, 32 ″ are not connected to each other at the ends of the wires 32, 32 ″ Since the metal plate material 2 is formed, the punching portion 21 is driven into the metal plate material 2 by the press machine B, and then the metal plate material 2 is simply pulled by the extender C. The material 3 can be easily manufactured.

In this case, since the punched portion 21 is a punched hole, the face material 3 having a large elongation rate can be manufactured.

Then, the upper and lower ends of the left and right vertical frames 11 having a groove 11a for tightly accommodating the vertical edge 3a of the face material 3 on at least the inner surface side of the face material 3 manufactured in this manner are connected by the horizontal frames 12 and 13. Since it is constructed by mounting it in the rectangular frame 1, the face material having high flexibility and poor independence has a stable planar shape while properly maintaining the vertical edge 3a of the face material 3 having a particularly weak waist. Can be kept in place and finished as a partition.

Although one embodiment of the present invention has been described above, the specific configuration of each part is not limited to the above-described embodiment.

For example, as shown in FIG. 13, the width W of the line 132 constituting the face material 103 is a substantially uniform width W2 except for a part, and may be configured to have a different width W1 in a part. .. By making the width W of the line 132 different in a part in this way, the hole 131 can be arbitrarily changed to some extent, and the shape and pattern of the finished face material 103 can be easily controlled.

Further, at the end of the line 32 constituting the face material 3 shown in FIG. 2, the face material 3 is cut along the DD line in the drawing and pressed into such a shape to form an adjacent line. An opening recess 31x may be provided between the rows 32 and 32. In this way, since the spreading conditions are the same, it is possible to homogenize the changes that occur in the course to some extent and to make it easier to stretch.

Further, as shown in FIG. 14, the punched portion 221 may have a slit shape only with a cut. In this way, it is effective when manufacturing a face material having a small elongation rate.

Of course, the combination of the punched hole and the slit is also effective.

Other configurations can be changed in various ways without departing from the spirit of the present invention.
