Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fastening device for a long member suitable for connecting a partition and a connecting structure of the partition using the same.
[0002]
[Prior art]
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.
[0003]
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.
[0004]
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.
[0005]
[Problems to be solved by the invention]
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.
[0006]
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.
[0007]
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.
[0008]
An object of the present invention is to improve this problem.
[0009]
[Means for Solving the Problems]
The present invention includes a fastening device for a long member and a connecting structure of a partition. Among them, the invention of claim 1 is formed such that the dovetail-shaped engaging groove is opened outwardly over the entire length. This is a fastening device that fixes two long members in a side- by-side state and in an overlapping state such that the engagement grooves communicate with each other.
[0010]
This fastening device includes a first clamp body which is inserted into an engagement groove of one elongated member from an end thereof and cannot be removed in a direction orthogonal to a longitudinal axis of the elongated member, and A second clamp body that is inserted into the engagement groove from the end thereof and cannot be removed in a direction perpendicular to the longitudinal axis of the long member ; and a second clamp body penetrates the second clamp body to attract both clamp bodies to each other . One clamp body is provided with a screwed headed bolt.
[0011]
The bolt is tilted with respect to the longitudinal axes of the long members so that the head is located near the end face of the long member, so that a tool such as a wrench or a driver rotates around the axis. The bolt can be rotated from outside the end face of the other elongated member.
[0012]
According to a second aspect of the present invention, in the first aspect, a hole or a groove for fitting a wrench or a driver is formed on a top surface of a head of the bolt.
[0013]
According to a third aspect of the present invention, in the first or second aspect, the two clamp bodies are provided with a fitting portion that fits so that only close contact and separation are possible.
[0014]
The invention according to claim 4 relates to a partition , in which the vertical frames of two units are connected in a state of being overlapped with each other, or the vertical frames of the units in the partition and the relay vertical frames are connected.
[0015]
The vertical frame is formed so that a dovetail groove opened on the outer surface and a hollow portion located inside the dovetail groove with the partition wall interposed therebetween extend over the entire length, and one of two overlapping vertical frames is provided. The first clamp body inserted from the end face of the dovetail groove is fitted to the end of the dovetail groove of the vertical frame so that it cannot be pulled out sideways, and the notch formed at the end of the partition wall of the other vertical frame has The two clamp bodies are fitted so that they cannot be displaced sideways and cannot move.
Further, the second clamp body has a bolt insertion hole through which a shaft of a headed bolt for attracting both clamp bodies penetrates, so that the bolt can be rotated from outside the end face of the other vertical frame. formed on the inclined position with respect to the longitudinal axis, the first clamping member, a screw hole which is inclined to the longitudinal axis of the longitudinal frame so that the shaft portion is screwed a bolt passing through said second clamping member The first clamp body and the second clamp body are connected to each other by a headed bolt to connect the two vertical frames.
[0016]
The invention according to claim 5 is configured by arranging a plurality of units whose left and right sides are constituted by vertical frames in a state of linearly extending in a plan view, and connecting and stacking the vertical frames of adjacent units with each other, Further, with respect to the partition in which the heights of two adjacent units are different, each vertical frame is provided with a dovetail groove opened on the outer surface and a hollow part located inside the dovetail groove with the partition wall interposed therebetween over the entire length. It is formed to extend.
[0017]
The first clamp body inserted from the end face of the dovetail groove is fitted into the dovetail groove of the vertical frame of the tall unit in such a manner that the first clamp body cannot be pulled out sideways, and the end of the partition wall of the vertical frame of the low height unit. The second clamp body is fitted in the notch formed in the part so that the second clamp body cannot be disengaged sideways and cannot move, and the second clamp body has a shaft part of a headed bolt for attracting both clamp bodies. The penetrating bolt insertion hole is formed in a posture inclined with respect to the longitudinal axis of the vertical frame so that the bolt can be rotated from the outside of the end surface of the vertical frame in the unit having a low height. are inclined screw hole is formed with respect to the longitudinal axis of the longitudinal frame so that the shaft portion of the bolt passing through the second clamping body is threaded, said first clamping member and a second clamping member Connecting the two vertical frames by attract each other with the head bolts.
[0018]
[Action and Effect of the Invention]
When the fastening device of the present invention is used, long members such as vertical frames of a unit in a partition can be firmly fastened (fixed) with bolts at their ends.
[0019]
In this case, by inclining the bolt with respect to the longitudinal axis of the elongated member, a hexagon wrench, a socket wrench, or a tool that rotates around the axis, such as a screwdriver, can be rotated from the outside of the elongated member. Even if another member is fixed to the measuring member, the fastening operation can be performed regardless of the structure of the other member.
[0020]
Therefore, when the present invention is applied to the connection of the partition units as in claims 4 and 5 , the structure of the horizontal frame is not limited, so that the design can be made versatile. Further, there is an advantage that the structure can be manufactured at low cost because the structure is simple.
[0021]
If a bolt with a hole or a groove is used as in claim 2, the wrench or driver for rotating the bolt is thinner than the head of the bolt, so that even a long member having a small sectional area can be reliably rotated. Particularly preferred. As the bolt, a bolt that can be rotated by a driver can be used. However, if a bolt with a non-circular hole such as a hexagonal bolt is used, a large torque can be applied with a wrench, and thus there is an advantage that the fastening strength is excellent.
[0022]
According to the structure of the third aspect, since the postures of both clamp bodies are kept constant, it is possible to easily fit the partition into a long member such as a vertical frame in the partition.
[0023]
The vertical frame of the partition is often formed to have the same cross-sectional shape by extrusion or the like, and it is easy to form a dovetail groove opened on the outer surface so as to extend over the entire length.
[0024]
According to the fourth aspect, the clamp body is fitted by using the dovetail groove of one vertical frame, and the other vertical frame is held so as not to fall by fitting the clamp body into the notch. Therefore, work can be easily performed in fastening the upper portions of the vertical fumes. The present invention is also particularly advantageous, as it allows the fastening of units having different heights .
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
[0026]
(1). Overview (Figure 1)
First, an outline of the partition will be described with reference to FIG. The partition is composed of first and second units 1 and 2 connected in an L-shape in plan view via a corner support 4 and a third unit 3 connected linearly to the second unit 2. I have.
[0027]
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.
[0028]
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.
[0029]
In this embodiment, each unit is provided with a pair of left and right vertical frames 5, but adjacent units 1 can share the 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.
[0030]
In the space surrounded by each of the units 1 to 3, a desk top plate 13 is detachably arranged . 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).
[0031]
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.
[0032]
(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.
[0033]
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.
[0034]
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.
[0035]
On the other hand, in each of the vertical frames 5, both front and rear surfaces 5a and an inner surface ( a 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.
[0036]
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.
[0037]
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.
[0038]
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.
[0039]
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.
[0040]
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.
[0041]
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 displaced sideways, and the bottom plate 27 is fastened by 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).
[0042]
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.
[0043]
Each of the vertical frames 5 has the same cross-sectional shape, and the outer surface has an uneven cross-section so that when the two vertical frames 5 are stacked in the front-reverse direction, they are fitted to each other and held so as not to be displaced back and forth. Is formed.
[0044]
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.
[0045]
(3). Lower connection structure (Figs. 3 to 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.
[0046]
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.
[0047]
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.
[0048]
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.
[0049]
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.
[0050]
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.
[0051]
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.
[0052]
Then, the adjacent vertical frames 5 are held so that they cannot be separated horizontally but not vertically. So that the vertical frames 5 of one can only be simultaneously fitted write to the pin 38 and the lower connection member 35, the height of the lower connecting member 35 is lower.
[0053]
(4). The upper connecting structure 36 is an embodiment of the fastening device according to 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.
[0054]
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.
[0055]
On both clamp bodies 40 and 41, these lips 40a so as not to escape sideways from the dovetail groove 17 and the notch 45, 41a are formed. 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.
[0056]
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. The protrusion 41b and the protrusion 40b are an example of the fitting part according to the third aspect.
[0057]
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.
[0058]
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 at the front is provided, and a bolt insertion hole 43 is formed in the inclined plate portion 41d.
[0059]
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.
[0060]
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.
[0061]
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.
[0062]
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.
[0063]
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).
[0064]
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.
[0065]
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.
[0066]
(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.
[0067]
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 (the 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.
[0068]
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).
[0069]
(6). Panel (Figs. 8 to 10)
Next, the panel will be described with reference to FIGS. Here, the first unit 1 will be described.
[0070]
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.
[0071]
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.
[0072]
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.
[0073]
At the upper end of the thin plate panel 10, an upper inclined portion 10c is formed which is in contact with or closely contacts 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.
[0074]
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.
[0075]
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.
[0076]
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.
[0077]
In the case of removal, an instrument 54 such as a flathead screwdriver may be inserted into the gap between the upper portion and the horizontal frames 6 to 8 and pryed forward.
[0078]
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.
[0079]

In each of the vertical frames, a dovetail groove opened on the outer surface, and a hollow portion located inside the dovetail groove across the partition wall are formed so as to extend over the entire length,
The first clamp body inserted from the end face of the dovetail groove is fitted into the dovetail groove of the vertical frame of the high unit in such a manner that the first clamp body cannot be pulled out sideways,
The second clamp body is fitted in the notch formed at the end of the partition wall in the vertical frame of the unit having a low height in such a manner that the second clamp body cannot be disengaged sideways and cannot move.
Further, the second clamp body has a bolt insertion hole through which a shaft of a headed bolt for attracting both clamp bodies penetrates, so that the bolt can be rotated from outside the end face of the vertical frame in the unit having a low height. to be formed on the inclined position with respect to the longitudinal axis of the vertical frame, the first clamping member, the shaft portion of the bolt extending through said second clamping member is inclined relative to the longitudinal axis of the vertical frame as screwed Screw holes are formed,
Connecting the two vertical frames by pulling the first clamp body and the second clamp body together with a headed bolt,
Partition.
