Description

  The present invention relates to a connecting structure of a partition unit, a clamp body for connecting the partition unit, and a combination of a clamp body for connecting the partition unit.

  In a partitioning screen, a unit in which a panel is attached to a frame (main body) formed by left and right vertical frames and a plurality of upper and lower horizontal frames is configured as a minimum unit. , L-shaped, cross-shaped, T-shaped, etc.

  When a plurality of units are connected in an L-shape, a cross shape, or a T-shape in plan view, they are often connected via a relay vertical frame (corner support) having a substantially square cross section.

  In any case, as a method of connecting the units or the unit and the relay vertical frame, conventionally, a connecting plate is overlapped on an upper horizontal frame of an adjacent unit, and the connecting plate is connected to an upper horizontal frame of both units. A clamping device provided with a cam mechanism for clamping the vertical frames of both units by a rotating operation of a lever or a method of fastening with a bolt has been adopted.

  When connecting partitions, it is required that they be connected firmly and that they can be connected by simple operations. In addition, since the unit cannot be disassembled at the time of connection, the fastening means must be operable from outside the unit. From such a viewpoint, a connection plate or a lever-type clamp device has been used.

  However, in order to use the connecting plate and the lever type clamp body device, the upper horizontal frame of the unit is formed with a groove with an upward opening for accommodating the connecting plate and the clamp body device, or a shade that hides them is installed. Must have been.

  For this reason, the conventional connection structure has a problem that the structure of the unit is limited, for example, it cannot be applied when the upper horizontal frame is hollow and does not have a cap. Further, the lever-type clamp device has a problem that the structure is complicated and the cost increases.

  An object of the present invention is to improve this problem.

  According to the invention of claim 1, one partition unit and another partition unit are connected such that their side ends overlap each other, or one partition unit and a relay vertical frame that overlaps the side ends thereof. With respect to a structure for connecting.

  According to the first aspect of the invention, the connection is performed by screwing a headed bolt that is rotated from above the one partition unit into a screw hole, and the posture in which the bolt is screwed into the screw hole. By setting the head upward and inclined with respect to the vertical line, it is possible to rotate the bolt with a tool from above one partition unit.

  According to the invention of claim 2, two partitioning units each having a hollow vertical side frame are connected so that the vertical frames overlap each other, or a hollow forming a side end of the partitioning unit is used. TECHNICAL FIELD The present invention relates to a structure for connecting a vertical frame and a relay vertical frame overlapping the vertical frame.

  The connection is performed by rotating a bolt from above the partition unit and screwing the bolt into the screw hole. The posture in which the bolt is screwed into the screw hole is tilted with the head upward and the vertical line. With this attitude, the bolt can be rotated from above the partition unit.

  According to a third aspect of the present invention, there is provided a case where one partition unit and another partition unit are connected in a state where their side ends are overlapped with each other, or one partition unit and a relay unit which is overlapped with its side ends. The present invention relates to a clamp body used when connecting a vertical frame.

  The clamp body is fitted into the end of the one partition unit from above and held so as not to drop. A bolt insertion hole through which the shaft of the headed bolt is inserted is vertically inserted into the clamp body. The clamp body is formed so as to extend in a direction inclined with respect to the line. Further, the clamp body is formed with an inclined surface to which the seat surface of the bolt is in close contact.

  The invention according to claim 4 is for connecting one partition unit and another partition unit in a state where their side ends overlap each other, or for one relay unit and a relay unit overlapping its side ends. Regarding a combination of clamp bodies used for connecting a vertical frame, the combination of the clamp bodies includes a first clamp body having a screw hole into which a headed bolt is screwed, and a bolt insertion through which a shaft portion of the bolt passes. A second clamp body having a hole.

  The first clamp body fits into the end of the other partition unit or the vertical frame for relay, and the second clamp body fits into the end of one partition unit from above and drops. The screw insertion hole of the second clamp body and the screw hole of the first clamp body are inclined with respect to the vertical line to rotate the bolt from above one partition unit. Is possible if possible.

Functions and effects of the invention

  ADVANTAGE OF THE INVENTION According to this invention, between partition units or a partition unit and a relay vertical frame can be firmly fastened (fixed) with a bolt.

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

  In the fourth aspect, when a fitting portion that fits so as to allow only close contact and separation is provided on both clamp bodies, the posture of both clamp bodies is kept constant, so that the vertical frame in the partition is There is an advantage that such a long member can be easily fitted.

  Next, an embodiment of the present invention will be described with reference to the drawings.

(1). Outline (Fig. 1)
First, an outline of the partition will be described with reference to FIG. The partition is linearly connected to the first and second partition units (hereinafter abbreviated as “units”) 1 to 3 connected in an L-shape in plan view via the corner supports 4 and the second unit 2. And a third unit.

  Each of the units 1 to 3 includes a vertical frame 5 arranged on the left and right, an upper horizontal frame 6 connecting between upper ends of the left and right vertical frames 5, a lower horizontal frame 7 connecting between lower ends of the left and right vertical frames 5, A frame is constituted by an intermediate horizontal frame 8 connecting the left and right vertical frames 5 between an upper end and a lower end, and panels 10, 11, and 12 are mounted in a frame space 9 surrounded by upper, lower, left and right frames, respectively. ing.

  The first unit 1 is divided into two upper and lower frame spaces by one intermediate horizontal frame 8, and the second unit 2 and the third unit 3 are divided into three upper and lower frame spaces by two intermediate horizontal frames 8. It is classified.

  In the present embodiment, a pair of left and right vertical frames 5 is provided for each unit. However, the adjacent units 1 can share a vertical frame. In addition to the upper and lower horizontal frames 6 and 7, it is also possible to arrange a coping and a baseboard separately.

  A desk top plate 13 is detachably mounted in a space surrounded by the units 1 to 3. One end of the tabletop 13 is supported by legs 14 (the units of the tabletop 13 may be supported in partitions by connecting the units in a U-shape in plan view). A shelf 15 can be freely attached to each unit 1 (the 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)
FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1. Based on FIG. 2, a cross-sectional structure of the corner support 4 and the vertical frame 5 will be described. The corner support 4 and the vertical frame 5 are extruded products of light metal such as aluminum, and therefore have basically the same cross-sectional shape over the entire length and are partially processed.

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

  A bottom plate 19 is fitted to the lower surface of the corner support 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 4a (see FIG. 4) is attached to the upper end of the corner support 4.

  On the other hand, in each of the vertical frames 5, the front and rear surfaces 5a and the inner surface (the surface facing the frame space 9) 5b are continuous via an arcuate curved surface 5c, and are formed in a hollow shape with a substantially trapezoidal cross section as a whole. I have. A dovetail groove 17 having the same shape as the corner support 4 is formed on the outer surface thereof. The dovetail groove 17 and the trapezoidal hollow portion are separated by a partition wall 5d.

  On the inner surface 5b of the vertical frame 5, a first inner engaging groove 22 having a front-rear width slightly smaller than the width dimension of the inner surface 5b and a shallow first inner engaging groove 22 is formed. 8 is adapted to fit tightly.

  Since the front and rear widths of the horizontal frames 6 to 8 are smaller than the front and rear widths of the vertical frame 5 (the thickness of the entire partition), even when the desk top plate 13 is placed on the front surface of the vertical frame 5 exactly, A routable space (recess) 24 through which the cords C and cables can be inserted is provided between the tabletop 8 and the tabletop 13.

  Each of the horizontal frames 6 to 8 is fastened to the vertical frame 5 by screws 25. Although not shown, the vertical frame 5 has a hole for inserting a screw 25 and a driver.

  In the first inner engaging groove 22 of the vertical frame 5, two second inner engaging grooves 23 are formed at both sides of the longitudinal center line in a divided state. These grooves 22 and 23 are an example of the engaging means described in the first aspect.

  A dovetail groove 26 for bracket is opened on both front and rear surfaces 5 a of the vertical frame 5, and a screw groove 18 having a substantially circular cross section in a flat section is formed in a state communicating with the dovetail groove 26 for bracket.

  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 shifted laterally, and the bottom plate 27 is fastened with screws 28 screwed into the screwing grooves 18. An adjuster bolt 29 is screwed into the bottom plate 27 from below. The upper surface of the vertical frame 5 is closed by a cap 30 (see FIG. 3).

  As shown in FIG. 6 (C), a bracket support plate 32 having a large number of slot holes 31 provided at appropriate intervals in the vertical direction is inserted into the bracket dovetail groove 26 from above. The shelf 15 and the table top 13 can be supported by the brackets fitted and mounted in the slots 31.

  The outer surfaces of the vertical frames 5 have the same cross-sectional shape. Is formed.

  When the dovetail groove 17 of the corner support 4 and the vertical frame 5 is exposed to the outside, it is 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 connecting structure (Figs. 3-7)
Next, a connection structure between units will be described mainly with reference to FIGS. 3 is a partially separated front view of a connecting portion between the second unit 2 and the third unit 3, FIG. 4 is a separated front view of a connecting portion between the corner support 4 and the second unit 2, and FIGS. FIG. 7 is a perspective sectional view taken along the line VII-VII of FIG.

  The connection structure between the corner supports 4 and the vertical frames 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 overlapping each other are connected by a lower connecting body 35 between lower ends, and are connected by an upper connecting device 36 between upper parts. First, the lower connecting structure will be described.

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

  In this example, the height of the second insertion portion 35b is low, and the second insertion portion 35b is formed with a step 35c. Further, an opening is formed at the lower end of the dovetail groove 17 in the other vertical frame 5 so as to correspond to the step 35 c of the lower connector 35. The lower connector 35 is supported by the bottom plate 27 of one of the vertical frames 5 so as not to fall.

  The adjacent vertical frames 5 are held by the lower connector 35 so as not to be horizontally separated. As shown in FIGS. 3 and 7, a hole 39 into which one pin 38 fits is provided at a lower portion of the adjacent vertical frame 5, and the adjacent vertical frame 5 is It is held irreversibly up and down.

  A notch 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 fall. Then, the pins 38 are mounted on the one vertical frame 5 and the lower connector 35 is fitted into the one vertical frame 5, and then the other vertical frame 5 is connected to the second insertion portion 35 b of the lower connector 35. The engagement 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 but not vertically. Since one vertical frame 5 is fitted into the pin 38 and the lower connector 35 at the same time, the height of the lower connector 35 is low.

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

  Both the clamp bodies 40 and 41 may be made of metal or synthetic resin, and the material may be selected according to the required fastening strength. The two 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, 41a are formed on both clamp bodies 40, 41 so that they do not come out from dovetail groove 17 and notch 45 in the horizontal direction. In addition, the convex portion 41b provided on the second clamp body 41 fits exactly into the dovetail groove 17 of one of the vertical frames 5.

  In addition, a projection 40b provided on the first clamp body 40 is fitted in a recess 41c formed in the convex portion 41b of the second clamp body 41 exactly. This is an example of a fitting portion in which the convex portion 41b, the protrusion 40b, and the two clamp bodies 40, 41 are fitted so that only the close contact and the separation are possible.

  Further, a bolt insertion hole 43 is provided in the convex portion 41 b of the second clamp body 41, while a screw hole 44 is provided in the projection 40 a of the first clamp body 40.

  At this time, the upper surface of the projection 40b of the first clamp body 40 is formed as an obliquely downward inclined surface 40c in a 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 has A flat inclined plate portion 41d overlapping 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 has the same groove width as the dovetail groove 17. Needless to say, since the upper connecting device 36 is supported at the bottom of the notch 45, the upper connecting device 36 is held so as not to fall even when the bolt 42 is loosened.

  Also, since the second clamp body 41 is fitted into the notch 45, the protrusion between the protrusion 41b and the protrusion 40b can be increased, so that the joint surface by the bolt 42 is increased to secure high fastening strength. it can.

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

  By setting the bolt 42 in the inclined position, the two 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 as possible to the horizontal as long as the insertion function of the hexagon wrench R is not impaired.

  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 can be fitted). Notches may be formed so that the heads of the bolts 52 do not interfere with each other).

  By the way, as shown by a chain line in FIG. 3, vertical frames 5 having different heights may be connected to each other (that is, units having different heights may be connected). When the upper horizontal frame 6 is hollow as in this embodiment, the conventional connecting plate or lever-type clamp device cannot be used at all.

  On the other hand, according to the present invention, the clamp bodies 40 and 41 can be inserted into the vertical frame 5 irrespective of the height of the adjacent vertical frame 5, and the bolts 42 of the lower vertical frame 5 Since the rotating 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.

(5). Horizontal frame (Figs. 8-9)
Next, the structure of the horizontal frames 6 to 8 will be described with reference to FIGS. 8 is a partial front view of the third unit 3, FIG. 9 is a sectional view taken along the line IX-IX of FIG. 8, and FIG. 10 is a perspective view of a main part.

  On both upper and lower surfaces of the horizontal frames 6 to 8, a center engaging groove 46 located at the center in the width direction and two side engaging grooves 47 located on both sides thereof are formed. The four corners of the horizontal frames 6 to 8 are chamfered in an arc shape (a chamfered portion is indicated by reference numeral 48). Further, on both front and rear surfaces of the horizontal frames 6 to 8, dovetail-shaped front engagement grooves 49 having a symmetric shape with respect to the vertical center line are formed.

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

(6). Panel (Figs. 8 to 10)
Next, the panel will be described with reference to FIGS. Here, the first unit 1 will be described.

  As shown in FIG. 9, in the upper frame space 9 of the three frame spaces 9 in the first unit 1, a thin panel 10 made of a cross-stretched metal plate or a decorative steel plate is arranged from the front and rear, and In the frame space 9, a medium-thick plate panel 11 such as a transparent or translucent resin plate is arranged from both sides.

  In the lower frame space 9, one hollow panel 12 formed of a metal plate in a hollow shape is fixedly arranged. The thin panel 10 and the middle panel 11 are arranged such that their outer surfaces are flush with the horizontal frames 6 to 8. On the other hand, the hollow panel 12 is thinner than the horizontal frames 6 to 8.

  At the lower end of the thin panel 10, a lower inclined portion 10a that abuts or comes into close contact with a continuous portion between the upper ends of the horizontal frames 6 to 8 and the chamfered portion 48, and a lower locking piece 10b that fits into the center engaging groove 46 Therefore, the thin panel 10 is held at the lower portion so that it cannot be moved back and forth.

  An upper inclined portion 10c is formed at the upper end of the thin plate panel 10 so as to contact or closely contact a continuous portion between the lower ends of the horizontal frames 6 to 8 and the chamfered portion 48. A folded portion 10d extending toward the inside of the wire 9 extends. Then, an upper locking piece 51 made of a leaf spring or the like that fits into the side engaging groove 47 of the horizontal frames 6 to 8 is fixed to the folded portion 10 d with a screw 50.

  There is a gap between the upper inclined portion 10c of the thin panel 10 and the chamfered portion 48 of the horizontal frames 6 to 8 such that a thin instrument 54 such as a flathead screwdriver can be inserted.

  The upper locking pieces 51 are partially provided at the upper end of the thin panel 10 (for example, when the width is about 900 mm, about two pieces are sufficient). As clearly shown in FIG. 10, a notch hole 53 is formed in the upper inclined portion 10 c of the thin plate panel 10 to facilitate the escape deformation of the upper locking piece 51.

  When the thin panel 10 is mounted, first, the lower locking piece 10b is fitted in the center engaging groove 46 of the lower horizontal frames 6 to 8 in a slightly inclined position, and then the upper locking piece is pushed by pressing the upper portion. What is necessary is just to fit 51 into the side engagement groove 47 of the upper horizontal frames 6-8.

  When 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 pryed forward.

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