Description

[Technical field]

[0001] The present invention relates to the technical field of simple partitions that are installed in rooms where many people gather, such as offices and lobbies. [Background technology]

[0002] Nowadays, in order to prevent infectious diseases, etc., partitions are often used to separate indoor spaces so that people do not face each other directly. As such partitions, partitions have been proposed in which both left and right edges of a rectangular partition plate are supported by vertical supports and are connected in the front, back, left and right directions to separate the space (see, for example, Patent Document 1). This type of partition is useful because the vertical supports have a structure that allows partition plates to be incorporated in up to four directions as necessary, making it possible to form partition spaces of any shape on site. In this type, the vertical supports have holding grooves that hold the partition plates extended in a cross shape from the central pillar base, making the vertical supports self-supporting. However, since the extension length of the holding grooves is short, the self-supporting function is low, and there is a problem that, for example, when a partition plate is formed by only supporting both left and right edges of a single partition plate with the vertical supports, it is prone to falling over. In response to this, a configuration has been proposed in which a leg seat that is long in the front-to-rear direction is provided at the lower edge of the vertical support, allowing the screen to stand stably and independently (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-9417 A [Patent Document 2] JP 2001-182199 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of a stand-alone type with the above-mentioned leg seat portion, the leg seat portion is long in the front-to-back direction, and therefore needs to be arranged at right angles to the partition board in order to ensure stable self-supporting function relative to the partition board.However, in the case of a stand-alone type with the leg seat portion configured to be freely rotatable relative to the vertical support, not only is it cumbersome and complicated to arrange the leg seat portion at right angles to the partition board, but there is also the problem that if the leg seat portion is rotated due to a person's foot hitting it, for example, its stable self-supporting ability will be compromised. It has therefore been proposed to make the leg seat part circular and have a vertical support pillar standing from the centre, thereby eliminating the directionality of the leg seat part; however, if one tries to store multiple leg seat parts together with the support rods attached to support the vertical supports, the leg seat parts must be stored apart by the radius at which the support rods abut against the outer periphery of the leg seat part, which creates problems such as the need for a large storage space, and these are the problems that this invention aims to solve. [Means for solving the problem]

[0005] The present invention has been made in view of the above-mentioned circumstances and with the objective of solving these problems. The invention of claim 1 relates to a simplified screen comprising a partition plate for dividing an indoor space, and vertical posts supporting both left and right end edges of the partition plate, the vertical posts being provided with a post base and a groove-shaped retaining groove portion extending from the post base and having a pair of retaining pieces for holding the end edges of the partition plate in a clamping manner, the vertical posts being provided with a disk-shaped leg having a support rod erected at the center thereof for supporting the vertical posts in an upright position by being inserted and removed freely into the lower end edges of the post base. This is a simplified partition wall having a seat portion, the leg seat portion being formed with a large diameter that exceeds the tip edge of the holding groove portion, and a storage notched groove portion being formed in the leg seat portion from the outer peripheral edge toward the central portion so that the support rod provided on another leg seat portion can pass through it and move from the outer peripheral edge toward the central portion so that the leg seat portions can be stored in a stacked state, the notched groove portion being formed so that the groove width is wider than the thickness of the partition plate and narrower than the outer width of the holding groove portion, and the groove depth is formed so that it does not reach the back of the groove position where the partition plate of the holding groove portion can be inserted. The invention of claim 2 is the simplified partition according to claim 1, characterized in that the leg seat portion is set so that the cutout groove portion is positioned below the holding groove portion that fits and holds the partition plate. The invention of claim 3 is the simplified partition according to claim 1 or 2, characterized in that the notched groove portion is formed so that the inner end of the groove is positioned at the open end portion of the holding groove portion. The invention of claim 4 is a simplified partition as described in any one of claims 1 to 3, characterized in that the four retaining grooves extend in a cross shape from the center, and a partition plate is fitted and held in at least one of the retaining grooves, and the leg seat portion is set so that the cutout groove portion is positioned below the retaining groove portion which fits and holds the partition plate. Effect of the Invention

[0006] According to the invention of claim 1, the partition has a large-diameter disk-shaped leg seat portion provided at the lower edge of the vertical support, and has high self-supporting function. When the leg seat portions provided with the support rods for inserting and supporting the vertical support are stored together, the support rods can be inserted into the notched grooves provided in the leg seat portions, allowing the leg seat portions to be stored compactly in a stacked state. When a partition plate is disposed above the notched grooves in this configuration, the groove width of the notched grooves is wider than the thickness of the partition plate but is smaller than the outer width of the holding grooves. Since the cutout groove is narrower than the lower edge of the partition plate, the inner edge of the cutout groove is arranged so that it almost runs along the lower edges of the front and back of the partition plate, making the presence of the cutout groove less noticeable and avoiding a loss of visibility. However, the cutout groove has a depth that does not reach the innermost position of the groove where the partition plate can be inserted. As a result, when the partition plate is arranged along the cutout groove, the edge supported by the retaining groove of the partition plate slides down into the cutout groove, avoiding the partition plate becoming tilted. By adopting the invention of claim 2, the screen has a partition plate disposed above the cut-out groove, so that even though the screen has a cut-out groove for storage, the presence of the cut-out groove is made inconspicuous, thereby preventing a loss of visibility. By adopting the invention of claim 3, the rear end of the cutout groove is positioned at the opening end portion of the retaining groove portion, and as a result, the left and right edge portions of the partition plate which are held in a clamped manner in the retaining groove portion are supported by the leg seat portion between the rear end position of the retaining groove portion and the opening portion, so that the partition plate can be stably supported even though the cutout groove portion is formed. By making use of the invention as claimed in claim 4, the vertical support has four retaining grooves extending in a cross shape from the base of the pillar, and a partition plate is fitted and held in at least one of these retaining grooves, the leg seat portion is set so that the cutout groove portion is positioned below the retaining groove portion which fits and holds the partition plate, thereby making it possible to avoid impairing visibility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a simple partition provided to separate people from one another, the partition 1 being configured to include a rectangular partition (partition) 2, a vertical support 3 for supporting both left and right end edges of the partition 2, and a disk-shaped foot rest 4 attached to the lower end edge of the vertical support 3 to make the vertical support 3 self-supporting, and the foot rest 4 is configured to separate the front and rear of the partition 2 by placing it on an appropriate placement surface such as a floor F or a desk surface in an indoor space, and the configuration of the partition 1 will be described in detail below.

[0009] In the present embodiment, the partition plate 2 is actually made of acrylonitrile or plastic corrugated board, but it goes without saying that various transparent, translucent or opaque plate materials can be used as needed, including hard synthetic resin materials with excellent transparency such as polycarbonate, glass plates, metal plates made of metal materials such as aluminum or stainless steel, decorative boards, cardboard plates made of paper, foam boards, etc., and the size of the partition plate 2 can be set to any size as needed. Meanwhile, the vertical supports 3 are fitted to support the left and right edge portions of the partition plate 2, and therefore in this embodiment, an extruded polyvinyl chloride material is used, but it may be made of various hard synthetic resin materials such as ABS, or even metals such as aluminum. Also, the leg base 4 is made of a metal plate made of steel, but it goes without saying that various metal plates such as stainless steel and brass, or even hard synthetic resin plates such as polycarbonate, may be used.

[0010] The vertical support 3 is composed of a pillar base 3a in which a hollow cylindrical bore 3b is formed, and four sets of retaining groove portions 3c extending in a cross shape in a planar view from the outer peripheral surface of the pillar base 3a. The retaining groove portions 3c are formed in the shape of a vertical groove with a pair of retaining pieces 3d facing each other with a gap in the horizontal direction (circumferential direction), and are configured in the shape of a dovetail with a groove entrance portion (opening end) 3e and a groove inner portion 3f which have approximately the same groove width, and a groove middle portion 3g which has a wider groove width than these. On the one hand, the partition plate 2 has a plate thickness equal to or slightly thicker than the groove widths of the groove inlet 3e and the groove bottom 3f of the holding groove 3c. By fitting and incorporating the left and right edge portions into the selected holding groove 3c of the vertical support 3, it is configured such that the partition plate 2 is fitted and supported in a lightly press-fitted state (clamped state) that fits into the groove inlet 3e and the groove bottom 3f.

[0011] Also, the pedestal portion 4 is configured using a large-diameter disc that extends beyond the tip edge of the holding groove 3c to a size sufficient to make the screen 1 self-standing. A support rod 5 is vertically attached to a through-hole 4a formed in the center portion. The support rod 5 is formed in a vertical rod shape with a screw hole 5a formed at the lower edge portion, and is vertically attached to the central portion of the pedestal portion 4 by screwing a screw 5b inserted from the lower surface of the pedestal portion 4 into the screw hole 5a. And by inserting and removing the column base 3a of the vertical support 3 into and from the support rod 5 attached to the central position of the pedestal portion 4 in this way, the vertical support 3 can be self-attached to the pedestal portion 4. The left and right edge portions of the partition plate 2 are configured to be fitted and incorporated into the holding groove 3c of the attached vertical support 3. Incidentally, on the support rod 5 of the present embodiment, when performing the screwing operation of the screw 5b with respect to the support rod 5 to attach and detach the support rod 5 to and from the pedestal portion 4, a chamfered portion 5c is provided on the circumferential surface so that the support rod 5 does not rotate together with the screw 5b. By performing a relative rotation operation of the screw 5b with respect to the support rod 5 while supporting the chamfered portion 5c with an appropriate tool such as a wrench, the support rod 5 can be easily attached to and detached from the pedestal portion 4.

[0012] Furthermore, a notch groove portion 4b is formed in the pedestal portion 4. The notch groove portion 4b is provided in a straight line (radial line) shape directed from the outer peripheral edge of the pedestal portion 4 toward the center portion. The groove width X is wider than the plate thickness Y of the partition plate 2 (X > Y) and narrower than the outer width Z of the holding groove 3c (X < Z). The groove end 4c of the notch groove portion 4b reaches up to the groove inlet 3e portion of the holding groove 3c and is formed so as not to reach the position of the groove bottom 3f into which the partition plate 2 of the holding groove 3c can be inserted.

[0013] When assembling the partition screen 1 by fitting the vertical support 3 and partition plate 2 to the leg base 4 to which the support rod 5 is attached, the vertical support 3 is first fitted into the support rod 5. In this case, the vertical support 3 is attached upright to the leg base 4 by externally fitting the lower end of the tubular hole 3b formed in the leg base 3a into the support rod 5, and the partition plate 2 is held in a clamped state in the holding groove 3c by fitting the left and right edge portions of the partition plate 2 into selected one of the holding groove portions 3c of the attached vertical support 3. In this case, it is preferable to rotate the leg base 4 or the vertical support 3 so that the partition plate 2 is positioned along the upper part of the cutout groove 4b. The minimum unit of a screen 1 is one that uses two sets of leg bases 4, two vertical supports 3, and one partition plate 2, but it is also possible to configure a screen 1 as shown in Figure 1, for example. In this case, there is a section where the partition plate 2 is not provided so that people can pass through the screen 1 from the inside to the outside (front and back), and in this case, a U-shaped connecting rod 6 is inserted into a cylindrical hole 3b to span between the upper edges of the pillar bases 3a of adjacent vertical supports 3, and this connecting rod 6 is used as a curtain rail to support a curtain 7 so that it can be opened and closed.

[0014] When the partition 1 embodying this invention is no longer needed, it can be disassembled and stored in a storage space such as a warehouse. In this case, the leg base portion 4 can be stored with the support rod 5 still attached and with the partition plate 2 and vertical support 3 removed, thereby preventing the loss or misplacement of small items such as the support rod 5 and screws 5b. When storing the leg base portion 4 with the support rod 5 attached, the leg base portion 4 can be stacked (overlapped) with the other leg base portion 4 in the cutout groove portion 4b of the other leg base portion 4, and the support rod 5 attached to the other leg base portion 4 can be inserted from the outer diameter side and moved to the back end of the groove, allowing the leg base portions 4 to be stored in a compact stacked state.

[0015] In the present embodiment configured as described above, a partition plate 2 for partitioning an indoor space, vertical columns 3 for supporting the left and right edge portions of the partition plate 2, and a pedestal portion 4 for improving the self-standing property of the vertical columns 3 are provided. In the simple screen 1 that can be disassembled and stored compactly when not in use, when storing a plurality of pedestal portions 4 in a state where a support rod 5 is provided at the center position to raise the vertical column 3, the support rod 5 provided on the other pedestal portion 4 is inserted into the notch groove 4b formed in one pedestal portion 4 to the groove bottom end portion 4c close to the center portion, so that the pedestal portions can be stacked and stored in a compact state. However, in this case, the groove width X of the notch groove portion 4b is wider than the plate thickness Y of the partition plate 2 (X>Y), but narrower than the outer width Z of the holding groove portion 3c (X<Z). As a result, when the notch groove portion 4b is arranged along the partition plate 2, the presence of the notch groove portion 4b can be made inconspicuous, and it is possible to avoid the visibility being impaired.

[0016] In this case, as a result of the groove depth of the notch groove portion 4b being up to the groove entrance portion 3e position that does not reach the groove bottom portion of the holding groove portion 3c into which the partition plate 2 is inserted, when the partition plate 2 is arranged along the notch groove portion 4b, it is possible to avoid a problem that the edge portion of the partition plate 2 supported by the holding groove portion 3c slips down into the notch groove portion 4b and the partition plate 2 becomes inclined. And as described above, when the partition plate 2 is arranged along the notch groove portion 4b, although the notch groove portion 4b for storage is provided in the pedestal portion 4, it is possible to avoid the visibility being impaired because the presence of the notch groove portion 4b becomes inconspicuous.

[0017] Moreover, in this case, as a result of the groove bottom end portion of the notch groove portion 4b being configured to be the groove entrance portion 3e of the holding groove portion 3c, the left and right edge portions held in a sandwiching state in the holding groove portion 3c of the partition plate 2 are supported in a state where the lower edge portion abuts from the groove bottom portion 3f of the holding groove portion 3c to the groove entrance portion 3e. Thus, although the notch groove portion 4b is formed, the partition plate 2 can be stably supported. Furthermore, in this device, the vertical support 3 is arranged in a cross shape with four retaining grooves 3c, and the partition plate 2 is fitted and held in at least one of the retaining grooves 3c. By setting the leg base 4 so that the cutout groove 4b is positioned below the retaining groove 3c into which the partition plate 2 is fitted, the partition groove 4b and the partition plate 2 are positioned on the same line, eliminating the unnatural look and preventing the loss of visibility.

[0018] Of course, the present invention is not limited to the above embodiment, and the partition may be a single partition plate 2, or may be a partition plate 1 that is used to form a room-like partitioned space as shown in Fig. 6(A). In addition, if the partition plate 2 is thin, the present invention can be implemented even if the spacer 8 is fitted onto the outer edge of the partition plate 2 and then fitted into the holding groove 3c. [Industrial Applicability]

[0019] INDUSTRIAL APPLICABILITY The present invention can be used as a simple partition to prevent people from facing each other or sitting next to each other. [Explanation of symbols]
