It is composed of a second clamp body that enters the vertical frame of the partition unit from above and cannot move to one partition unit side, and a headed bolt that attracts both the clamp bodies and fastens the vertical frame of the partition unit. The bolt is passed through the second clamp body by rotating with a tool from above the other partition unit in a posture inclined with respect to the vertical line with the head up, and passes through the second clamp body. Therefore, the screw hole of the first clamp body is also inclined with respect to the vertical line, and further, the second clamp The flop body forms an inclined surface seat of the bolt overlap.

In the partition device according to the invention of claim 2, first, a partition unit whose side end portion is configured by a vertical frame, a relay vertical frame, and the vertical frame of the partition unit and the relay vertical frame are fastened. The vertical frame of the both partition units and the vertical frame for relay are both formed in a hollow shape and the side surfaces overlap each other.

The upper connecting device includes a first clamp body that enters one of the vertical frames from above and cannot move to the other vertical frame, and the other vertical frame of the two vertical frames. It is composed of a second clamp body that enters inside from above and cannot move to the side of one vertical frame, and a headed bolt that attracts both the clamp bodies and fastens both the vertical frames, By rotating with a tool from above the other vertical frame in a posture inclined with respect to the vertical line with the head up, the second clamp body is penetrated and screwed into the first clamp body. For this reason, the screw hole of the first clamp body is also inclined with respect to the vertical line, and the second clamp body is formed with an inclined surface on which the seating surface of the bolt overlaps.

Effects and effects of the invention

  According to the present invention, the partition units or the partition unit and the relay vertical frame can be firmly fastened (fixed) with the bolts.

  And by tilting the bolt with respect to the vertical line, the bolt can be rotated from above the partition unit with a tool that rotates around the axis, such as a hexagon wrench, socket wrench, or screwdriver. Can do. Moreover, even if the heights of the partition units or between the partition units and the relay vertical frame are different, they can be easily and firmly connected.

  A table top 13 is detachably attached to the space surrounded by the units 1 to 3. One end of the tabletop plate 13 is supported by a leg 14 (the whole tabletop plate 13 may be supported by a partition by connecting the units in a U shape in plan view). A shelf 15 can be freely attached to each unit 1 (support structure will be described later).

  In the illustrated example, each of the units 1 to 3 has the same vertical dimension and width dimension, but it is also possible to prepare a plurality of types of units having different widths and heights.

(2). Corner support and vertical frame (Fig. 2)
2 is a cross-sectional view taken along the line II-II in FIG. 1, and the cross-sectional structure of the corner column 4 and the vertical frame 5 will be described based on FIG. The corner support 4 and the vertical frame 5 are extruded products of light metal such as aluminum, and therefore basically have the same cross-sectional shape over the entire length and are partially processed.

  The corner column 4 is formed in a hollow shape with a substantially square shape in plan view, and a dovetail groove 17 is formed on each outer surface so as to extend over the entire length. Also, screwing grooves 18 having a substantially arc shape in a plan view are formed at four positions slightly inside the four corners.

  A bottom plate 19 is fitted to the lower surface of the corner column 4 so as not to be laterally displaced, and the bottom plate 19 is fastened by a screw 20 screwed into the screwing groove 18. An adjuster bolt 21 is screwed into the bottom plate 19 from below. A top cap 4 a (see FIG. 4) is attached to the upper end of the corner column 4.

  On the other hand, each vertical frame 5 has a front and rear double-sided surface 5a and an inner surface (surface facing the frame space 9) 5b continuous through an arcuate curved surface 5c, and is formed in a hollow shape with a substantially trapezoidal cross section as a whole. Yes. And the dovetail groove 17 of the same shape as the corner support | pillar 4 is formed in the outer surface. The dovetail groove 17 and the trapezoidal hollow part are partitioned by a partition wall 5d.

  A shallow first inner engagement groove 22 is formed on the inner surface 5b of the vertical frame 5 and has a front and rear width slightly smaller than the width dimension of the inner surface 5b, and each of the horizontal frames 6 to 6 is formed in the first inner engagement groove 22. The end of 8 fits tightly.

  Since the front-rear width dimension of the horizontal frames 6-8 is smaller than the front-rear width dimension of the vertical frame 5 (thickness of the entire partition), the horizontal frame 6- Between 8 and the tabletop board 13, a routable space (recess) 24 through which the cords C and cables can be inserted is vacant.

  The horizontal frames 6 to 8 are fastened to the vertical frame 5 with screws 25. Although not shown, the vertical frame 5 has a hole for inserting a screw 25 and a screwdriver.

  In the first inner engagement groove 22 of the vertical frame 5, two second inner engagement grooves 23 are formed at positions on both sides of the longitudinal center line. Both the grooves 22 and 23 are an example of the engaging means described in claim 1.

  A bracket dovetail groove 26 is opened on both front and rear surfaces 5 a of the vertical frame 5, and a screwing groove 18 having a substantially arcuate cross section is formed in communication with the bracket dovetail groove 26.

  A bottom plate 27 also shown in FIG. 6B is fitted to the lower surface of the vertical frame 5 so as not to be laterally displaced, and the bottom plate 27 is fastened by a screw 28 screwed into the screwing groove 18. The bottom plate 27 is screwed with an adjuster bolt 29 from below. The upper surface of the vertical frame 5 is closed with a cap 30 (see FIG. 3).

  As shown in FIG. 6 (C), a bracket support plate 32 having a large number of slots 31 spaced at an appropriate vertical interval is inserted into the bracket dovetail groove 26 from above. The shelf 15 can be supported or the tabletop 13 can be supported by the bracket fitted in and attached to the slot 31.

Each vertical frame 5 has the same cross-sectional shape, and the outer surface has a cross-sectional uneven shape so that when the two vertical frames 5 are overlapped in the front-rear direction, they are fitted to each other and are held undisplaceable. Is formed.

  In the case where the corner posts 4 and the dovetails 17 of the vertical frame 5 are exposed to the outside, they are closed by a detachable end cover 33. A cap 30 (see FIG. 4) is attached to the upper end of the vertical frame 5.

(3). Lower connection structure (Figs. 3-7)
Next, the connection structure between the units will be described mainly with reference to FIGS. FIG. 3 is a partially separated front view of the connecting portion between the second unit 2 and the third unit 3, FIG. 4 is a separated front view of the connecting portion between the corner column 4 and the second unit 2, and FIGS. FIG. 7 is a perspective sectional view taken along the line VII-VII in FIG.

  The connection structure between the corner column 4 and the vertical frame 5 and the connection structure between the vertical frames 5 are basically the same. Here, the connection between the vertical frames will be mainly described.

  The vertical frames 5 that overlap each other are connected to each other at the lower ends by a lower connecting body 35, and the upper portions are connected to each other by an upper connecting device 36. First, the lower connection structure will be described.

  For example, as can be easily understood from FIG. 5, the lower coupling body 35 has a first insertion portion 35 a that fits into the dovetail groove 17 of one vertical frame 5 from below and a dovetail groove 17 of the other vertical frame 5 below. And a second insertion portion 35b that fits tightly.

  In this example, the height of the second insertion portion 35b is low, and the step portion 35c is formed in the second insertion portion 35b. The opening at the lower end of the dovetail groove 17 in the other vertical frame 5 forms a notch 37 corresponding to the step 35 c of the lower connector 35. The lower connecting body 35 is supported by the bottom plate 27 of one vertical frame 5 so as not to drop.

  The adjacent vertical frames 5 are held by the lower coupling body 35 so as not to be horizontally separated. As shown in FIGS. 3 and 7, a hole 39 into which a single pin 38 is fitted is formed in the lower part of the adjacent vertical frame 5, and the adjacent vertical frame 5 is formed by this pin 38. It is held inseparable up and down.

  A cutout is formed at the opening edge of the dovetail groove 17 in the vertical frame 5 so that the large diameter portion of the pin 38 is caught so as not to drop. The pin 38 is attached to one vertical frame 5 and the lower connecting body 35 is fitted to the one vertical frame 5, and then the other vertical frame 5 is connected to the second insertion portion 35 b of the lower connecting body 35. The engaging hole 39 is fitted into the pin 38 while being fitted into the pin 38.

  Then, the adjacent vertical frames 5 are held so that they cannot be separated horizontally and cannot be separated vertically. Since the vertical frame 5 is fitted into the pin 38 and the lower connecting body 35 at the same time, the height of the lower connecting body 35 is low.

(4) Upper connection structure The upper connection device 36 embodies the present invention, and includes a first clamp body 40 fitted into the dovetail groove 17 of one vertical frame 5 from above and a partition wall of the other vertical frame 5. It consists of a second clamp body 41 fitted from above into a notch 45 of an upward opening formed in 5d, and a bolt (hexagon socket socket bolt) 42 for attracting them.

  Both clamp bodies 40 and 41 may be made of metal or synthetic resin, and a material may be selected according to the required fastening strength. Both clamp bodies 40 and 41 may be made of synthetic resin, and a metal nut may be embedded in the first clamp body 40 or fitted from the back side.

  Lips 40a and 41a are formed on both clamp bodies 40 and 41 so as not to be laterally removed from the dovetail groove 17 and the notch 45. Further, the convex portion 41 b provided on the second clamp body 41 is fitted into the dovetail groove 17 of one vertical frame 5 exactly.

And the protrusion 40b provided in the 1st clamp body 40 fits exactly in the recess 41c formed in the convex part 41b of the 2nd clamp body 41. As shown in FIG. The convex portion 41b and the protrusion 40b are an example of a fitting portion that fits both the clamp bodies 40 and 41 so as to allow only close contact and separation.

  Furthermore, a bolt insertion hole 43 is vacant in the convex portion 41 b of the second clamp body 41, while a screw hole 44 is vacant in the protrusion 40 a of the first clamp body 40.

  At this time, the upper surface of the protrusion 40b of the first clamp body 40 is formed as an inclined surface 40c obliquely downward in front view, and the screw hole 44 is opened in the inclined surface 40c, while the convex portion 41b of the second clamp body 41 is A flat plate-like inclined plate portion 41d that overlaps the inclined surface of the first clamp body 40 in a front view is provided, and a bolt insertion hole 43 is formed in the inclined plate portion 41d.

  The notch 45 is formed in the same groove width as the dovetail groove 17. Needless to say, since the upper coupling device 36 is supported by the bottom of the notch 45, the upper coupling device 36 is held so as not to fall even when the bolt 42 is loosened.

  Moreover, since the protrusion dimension of the convex part 41b and the protrusion 40b can be enlarged by inserting the 2nd clamp body 41 in the notch 45, the joining surface by the volt | bolt 42 is enlarged and high fastening strength is ensured. it can.

  Both clamp bodies 40 and 41 are temporarily fixed with bolts 42 so as not to separate. In order to connect the units, the adjacent vertical frames 5 are overlapped, and the lower part is first connected by the lower connecting body 35 and the pin 38, and then clamped in the dovetails 17 of both the vertical frames 5, respectively. The bodies 40 and 41 are inserted, and then the hexagon wrench R is fitted into the head of the bolt 42 from above and is screwed. Thereby, both the vertical frames 5 are firmly fastened in the upper part.

  Since the bolts 42 are inclined, both the vertical frames 5 can be firmly fastened using the hexagon wrench R without cutting the inner surface of the vertical frame 5. It is preferable that the inclination angle of the bolt 42 be as close to horizontal as possible within a range that does not impair the insertion function of the hexagon wrench R.

  If the dovetail groove 17 has a certain depth, both clamp bodies 40 and 41 can be fitted into the dovetail groove 17 of the vertical frame 5 (in this case, the partition wall 5d of the other vertical frame 5 A notch may be formed so that the head of the bolt 52 does not interfere).

  By the way, as indicated by a one-dot chain line in FIG. 3, the vertical frames 5 having different heights may be connected (that is, units having different heights may be connected). And when the upper horizontal frame 6 is hollow like this embodiment, the conventional connection plate and lever type clamping device cannot be used at all.

  On the other hand, in the present invention, the clamp bodies 40 and 41 can be inserted into the vertical frame 5 regardless of the height of the adjacent vertical frames 5, and the bolts 42 can be inserted at the positions of the vertical frames 5 having a low height. Since the rotation operation can be performed, even the vertical frames 5 having different heights can be easily and firmly fastened. Therefore, the present invention is particularly useful when fastening units having different heights.

Further, the four corners of the horizontal frames 6 to 8 are chamfered in an arc shape (the chamfered portion is indicated by reference numeral 48). Furthermore, symmetrical front dovetail grooves 49 sandwiching the vertical center line are formed on both front and rear surfaces of the horizontal frames 6-8.

  Inside the horizontal frames 6 to 8, a screw groove 18 having an arcuate cross section extending along the center line is formed, and the vertical frame 5 and the horizontal frame 6 are formed by screws 25 screwed into the screw groove 18. ˜8 are fastened (see also FIG. 2).

  Further, in the lower frame space 9, a single hollow panel 12 formed in a hollow shape with a metal plate is fixedly disposed. The thin plate panel 10 and the middle thickness panel 11 are arranged so that the outer surfaces thereof are flush with the horizontal frames 6 to 8. On the other hand, the hollow panel 12 is thinner than the horizontal frames 6-8.

  At the lower end of the thin plate panel 10, there are a lower inclined portion 10 a that comes into contact with or closely contacts a connecting portion between the upper ends of the horizontal frames 6 to 8 and the chamfered portion 48, and a lower locking piece 10 b that fits in the center engaging groove 46. For this reason, the thin panel 10 is held in the lower part thereof so as not to be able to move back and forth.

  Further, an upper inclined portion 10c is formed at the upper end of the thin plate panel 10 so as to be in contact with or in close contact with the connecting portion between the lower ends of the horizontal frames 6 to 8 and the chamfered portion 48. The folding | returning part 10d extended toward the inside of 9 is extended. Then, an upper locking piece 51 such as a leaf spring that is fitted into the side engagement grooves 47 of the lateral frames 6 to 8 is fixed to the folded portion 10 d with a screw 50.

  A gap is formed between the upper inclined portion 10c of the thin panel 10 and the chamfered portion 48 of the horizontal frames 6 to 8 so that a thin instrument 54 such as a flat-blade screwdriver can be inserted.

  The upper locking pieces 51 are partially provided on the upper end portion of the thin panel 10 (for example, about two pieces may be used when the width is about 900 mm). As clearly shown in FIG. 10, the upper inclined portion 10 c of the thin panel 10 has a notch hole 53 for facilitating the deformation of the upper locking piece 51.

  When the thin panel 10 is attached, first, the lower locking piece 10b is fitted into the center engaging groove 46 of the lower horizontal frames 6 to 8 in a slightly forward inclined posture, and then the upper locking piece is pushed by pushing the upper part. 51 may be fitted into the side engaging grooves 47 of the upper horizontal frames 6-8.

  In the case of removing, an instrument 54 such as a flathead screwdriver may be inserted into the gap between the upper part and the horizontal frames 6 to 8 and twisted forward.

  A lower locking piece 10 c and an upper locking piece 51 are fixed to the upper end portion and the lower end portion of the middle thickness panel 11 with screws 56 via a contact plate 55. A boss 55a into which the screw 56 is screwed is formed integrally with the contact plate 55. The procedure for attaching / removing the middle thickness panel 11 is the same as that for the thin panel 10.
