  However, as in the partition disclosed in Patent Document 1 described above, the one that can be folded via a hinge is compacted by folding, but one panel and the one panel via the hinge Since it cannot be folded unless it is operated so as to overlap with the other connected panel, when folding from the expanded state, or in order to change from the folded state to the expanded state, a predetermined wide area is required. Must be secured. In addition, since the partition panel disclosed in Patent Document 2 cannot be installed unless a rail is attached to the ceiling, it cannot be installed in places where the ceiling is extremely high, such as a factory, or outdoors where there is no ceiling in the first place. Can not. In addition, in a structure that is expanded and contracted using a pantograph-like member like the gate disclosed in Patent Document 3, it is necessary to fix a column that stands up from the ground. Can not do it.

  Therefore, the present invention has been proposed in order to solve the problems of the various conventional space partition structures described above, and is operated in a direction intersecting with the expansion / contraction direction when performing the expansion / contraction operation. A new space partition structure that can be operated in a straight line without having to be moved in the intersecting direction, and that there is no need to use a ceiling at all, and there is no need to provide a specific support. It is intended to provide.

  The present invention has been proposed in order to solve the above problems, and the first invention (the invention according to claim 1) is characterized in that a plurality of large and small partition members each having a housing space formed therein are nested. Each partition member excluding the outermost partition member is made to be stretchable as a whole by sliding, and at least each partition member excluding the outermost partition member The caster is arranged, and the specific partition member and the other partition member arranged outside the specific partition member are removed from the specific partition member. An extraction restricting member for preventing the insertion is relatively formed, and when the specific partition member is inserted into the other partition member, an insertion for restricting insertion more than a predetermined amount is inserted. It is characterized in that the regulating member is formed.

  In the first invention, when the specific partition member located on the innermost side is pulled out in a state where the overall length is reduced most, the specific partition member remains in a self-supporting state by rolling the caster. When the specific partition member is extracted in a straight line from another partition member located outside the partition member and is extracted over a predetermined length, the specific partition is further removed by the extraction restriction member. The member cannot be extracted from the other partition member, and as a result, the other partition member (specific partition member here) is further extracted from the other partition member. In this manner, each partition member is sequentially extracted from the innermost partition member, and all the partition members except the largest partition member located on the outermost side are pulled out, so that the most extended state is obtained. It becomes.

  Then, in the space partition structure that is in the most extended state as described above, the specific partition member positioned on the innermost side is inserted into another partition member positioned on the outer side of the specific partition member. When it is operated and inserted to a predetermined position, it can no longer be inserted by the insertion restricting member, and another partition member is inserted into the partition member located outside, and finally All of the other partition members are accommodated in the accommodation space formed in the outermost partition member.

  Therefore, according to the space partition structure according to the first aspect of the present invention, there is no need to operate in the direction intersecting the expansion / contraction direction or move the member in the intersecting direction when performing the expansion / contraction operation. Since each partition member is self-supporting, it is not necessary to use the ceiling at all, and it is not necessary to provide a specific support. In addition, the shape of each partition member which comprises this invention should just be the shape overlapped so that it may be nested, and may be square shape, a triangular shape, or a geometric shape.

  Further, according to a second invention (invention of claim 2), in the first invention, the partition member located on the outermost side and the partition member located on the innermost side among the plurality of partition members, Left and right leg members are disposed, and these left and right leg members have a length in a direction perpendicular to the expansion and contraction direction of the whole of the plurality of partition members from a state having a length in the height direction of the partition members. It is characterized in that it can be rotated over a state in which the tip side abuts on the ground.

  The left and right leg members constituting the space partition structure according to the second invention are respectively disposed on both the outermost partition member and the innermost partition member. From the state having a length in the height direction of the partition member, centering on the moving axis, to the state in which the length is in a direction perpendicular to the expansion and contraction direction of the whole of the plurality of partition members and the tip side comes into contact with the floor or the ground. And can be rotated. That is, when it is not used as a leg member, it can be in a state having a length in the height direction of the partition member, and when used as a leg member (function), it is orthogonal to the expansion / contraction direction of the entire partition member. It can be made into the state which has a length in the direction and the front end side contacts the floor or the ground.

  Therefore, according to the space partition structure according to the second aspect of the present invention, the independence can be made more stable, and inadvertent falling can be effectively prevented. In addition, when the leg member is not used, the leg member can be in a state having a length in the height direction of the partition member. Therefore, the leg member is not used for partitioning the space, for example, when stored in a warehouse or the like. It can be made compact, and the leg member can be prevented from getting in the way.

  In addition, according to a third invention (invention according to claim 3), in any of the first and second inventions, each of the partition members includes a front side plate portion and a rear side plate portion, and these front surfaces are provided. The side plate portion and the back side plate portion are each formed with an opening, and a closing plate is attached to each opening. The closing plate is integrally formed with a resin that is transparent or colored and transparent. The side surface or the outer surface is coated with a reflection film that reflects a laser beam, or is made of a resin to which a laser beam absorber is added.

  For example, acrylic resin or polycarbonate resin can be used as the transparent or colored transparent resin. In addition, as the reflective film for reflecting the laser beam, for example, aluminum or a protective coating of magnesium fluoride (MgF2) on the aluminum, or a protective coating of silicon monoxide (SiO) on the aluminum. It may be a thing. In addition to these, gold may be coated as a reflective film. Moreover, as said laser beam absorber, inorganic materials, such as polyphenylene sulfide (PPS), carbon black, titanium oxide, zinc oxide, can be used, for example.

  According to the above-described space partition structure according to the third invention, by using the space partition structure as a partition surrounding the periphery of a laser processing machine using a fiber laser or a YAG laser, the laser beam can be used by the operator. Without damaging the eyes, the laser beam machine can be viewed from the outside through the closing plate. That is, the space partition structure according to the third aspect of the invention can be said to be a cover device for a laser processing machine that covers the periphery of the laser processing machine, and is independent of the laser processing machine. Therefore, it can be moved and transported separately from the laser processing machine, and the distance from the laser processing machine can be arbitrarily selected. In this respect, as compared with a cover device integrated with a laser processing machine, it is possible to avoid an increase in the size of the laser processing machine, such as a container that cannot be accommodated in a certain volume, such as a container. In addition, by using a separate cover device for a laser processing machine, there is also an effect that it can be accommodated in a certain volume.

  According to a fourth invention (invention of claim 4), in any one of the first to third inventions, at least one of the left side plate portion and the right side plate portion plate of each partition member includes a sun An inclined plate portion to which the optical panel is attached is formed.

  The space partition structure according to the fourth aspect of the present invention is installed outdoors where sunlight is irradiated, and is used for partitioning a parking space or an open space. It can be used as a solar panel installation space.

  According to the space partition structure according to the first aspect of the present invention (invention of claim 1), when performing an expansion / contraction operation, an operation is performed in a direction crossing the expansion / contraction direction, or a member is moved in the crossing direction. It is possible to operate in a straight line without having to do, and since each partition member is self-supporting, it is not necessary to use the ceiling at all, and it is not necessary to provide a specific support. In other words, according to the space partition structure according to the present invention, since it is not necessary to perform the folding operation, it can be used even in a narrow space, and each partition member has a self-supporting property. Therefore, there is no need to suspend and support from the ceiling, or one end side is supported by a support column, and it can be installed freely without restricting the use environment both outdoors and indoors.

  Moreover, according to the space partition structure according to the second invention (the invention described in claim 2), the independence can be made more stable, and it is possible to effectively prevent inadvertent falls. Can do. In addition, when the leg member is not used, the leg member can be in a state having a length in the height direction of the partition member. Therefore, the leg member is not used for partitioning the space, for example, when stored in a warehouse or the like. It can be made compact, and the leg member can be prevented from getting in the way.

  Moreover, according to the space partition structure according to the third invention (invention of claim 3), it is used as a space partition structure as a partition surrounding the periphery of a laser beam machine using a fiber laser or a YAG laser. Thus, the laser beam machine can be visually recognized from the outside through the blocking plate without damaging the eyes of the operator with the laser beam.

  Moreover, according to the space partition structure which concerns on 4th invention (invention of Claim 4), it can be used in order to partition a parking lot space, a vacant land, etc. by installing in the outdoors irradiated with sunlight.
