Abstract

The present invention provides an assembling jig, a connecting tool thereof, and a guide plate for assembling a plurality of frames smoothly and reliably. An assembly jig comprises a guide plate (12) and a pair of connectors (14). After the guide plates are placed on the pair of frames F that are perpendicular to each other, the post-attaching type couplings are individually attached to the frames and the guide plates, respectively, so that workability is improved. Since the direction of the flange portion 24B of the operating body 24 is the same direction as the direction of the tip of both the engaging surfaces 20A of the engaging body 20, the operator can easily determine the direction of the tip of the engaging body by visually checking the flange portion 24B. can be judged. Further, even if the tip of the engaging member of the connecting member bites into the lower surface of the thin piece F2 forming the engaging groove F3 of the frame, the engaging member and the operating portion can be integrally screwed together via the screw shaft 16. Since they are connected, the rotational force of the operating part is directly transmitted to the engaging body. That is, the attachment and detachment of the coupler with respect to the frame and the guide plate becomes smooth and quick, and usability is improved. [Selection drawing] Fig. 8

Description

TECHNICAL FIELD The present invention relates to an assembly jig for temporarily fixing and assembling a plurality of frames and a connector thereof .

When assembling a plurality of frames F on the market shown in FIG. 11 by connecting them (see FIG. 15), the assembling jig shown in FIG. Tool 100 is used. This assembly jig 100 includes a pair of butterfly bolts 102, a connecting plate 104 having round holes 105 slightly larger in diameter than the threaded portions 102A of the butterfly bolts 102 at appropriate intervals, and a connecting plate 104 having the wing bolts 102 mounted thereon. It has a pair of nuts 106 attached via (see FIG. 13). The butterfly bolt 102 has a head portion 102B larger in diameter than the screw portion 102A and a pair of flange portions 102C projecting from the head portion 102B.

When assembling a plurality of frames F in a T shape, for example, as shown in FIG. The assembly jig 100 as a whole is appropriately placed as a set on the frame F so as to substantially correspond to the opening grooves F1 (see the dashed line in FIG. 16 and the dashed line in FIG. 13). That is, as shown in FIG. 13, the threaded portion 102A and nut 106 of the left butterfly bolt 102 are inserted into the opening groove F1 of the frame F indicated by the dashed line in FIG.

From this inserted state, the wing bolt 102 is appropriately rotated, and the T-shaped head 107 of the nut 106 freely rotatable with respect to the wing bolt 102 forms the opening groove F1 indicated by the one-dot chain line in FIG. (that is, the back surface formed by the wide engagement groove F3 continuous to the opening groove F1) of the groove piece F2 (that is, the back surface formed by the wide engagement groove F3 continuous to the opening groove F1) is screwed until it is caught (synonymous with so-called "engagement"). That is, by screwing the wing bolt 102 and the nut 106, as shown in FIG. The plate 104 is pressed against and clamped against the groove piece F2 of the frame F (that is, synonymous with "mounting of the assembly jig 100").

In addition, Patent Document 1 discloses an assembly jig that can accurately position and fix structural members together when assembling a frame (see "Problem" column in "Summary"). That is, this assembly jig has a guide rail that can be detachably attached to the vertical member, and a guide block that can be detachably attached to the horizontal member is attached to the guide rail so as to be movable up and down. Further, there is disclosed a configuration in which a height adjustment bolt is loosely inserted into the adjustment block for moving a guide block equipped with a plurality of T bolts (see paragraph number "0016") up and down with respect to the guide rail (see "Abstract"). See “Solution” column).

On the other hand, in Patent Document 2, in order to facilitate the frame assembly work, the first and second fixing means are provided with a first fixing portion and a second fixing portion that can be inserted into the frame groove, and these fixing portions are provided. It has a first knob and a second knob that are manually rotated via a first rotating shaft and a second rotating shaft. An assembly jig is disclosed for fixing the long side of the abutment surface of each fixing portion perpendicular to the extending direction of the frame groove (see "Abstract" column).

Then, in the conventional example shown in FIG. 12, each assembly jig 100 of Patent Document 1 and Patent Document 2, etc., the frame F Fix them together with bracket B. That is, after assembling the frames, the frames F are securely fixed to each other in a temporarily fixed state with hexagon socket bolts BB via brackets B shown in FIGS. 15 to 17 (see FIG. 17). It should be noted that the assembly jigs 100 and the like described above are configured to be attached to and detached from the frame F as a whole set.

Registered Utility Model No. 3080481 JP 2016-156390 A

By the way, in the conventional example shown in FIG. 12, the connecting plate 104 (see FIGS. 12 to 14) through the T-shaped head 107 of the nut 106 and the head 102B of the wing bolt 102, and in Patent Document 1, the T-bolt and the wing nut are connected. The intervening block body (see paragraph number "0016" and FIG. 1) must be held in opposing pressure contact with the groove pieces F2 (see FIGS. 11 and 13) of the frame F, respectively. However, with respect to the opening grooves F1 of the frames F, the directions of the plurality of T-shaped heads 107 (see FIG. 12) provided in the assembly jig 100 and the like and the T-bolts according to Conventional Example 1 are aligned with the opening grooves F1. It may be difficult in terms of work to make them correspond to each other. That is, in the conventional example shown in FIG. 12 and Patent Document 1, when temporarily fixing the assembly jig, it is difficult to perform a plurality of screw fixing operations substantially simultaneously depending on the working posture of the operator.

In addition, in each of the assembly jigs 100 and the like described above, when removing them, the T-shaped head 107 and the tip of the T-bolt according to Patent Document 1, etc., are smoothly engaged while biting into the groove piece F2 of the frame F shown in FIG. It may not return to the state at the time of insertion (the state of FIG. 13). Therefore, it may be necessary to disassemble the wing bolt 102 and the nut 106, which complicates the work. That is, in the conventional example shown in FIG. 12 and Patent Document 1, when the assembly jig 100 and the like are attached to and detached from the frame F, the assembly jig 100 and the like are performed as a set.

On the other hand, in Patent Document 2, unlike the conventional example shown in FIG. 12 or Patent Document 1, when the knob (rotating shaft) is rotated by 90°, the fixed portion also rotates in the same direction by the same angle (see paragraph number “0024” and FIG. 3B). ), the abutment surface of the fixed portion is pressed against or separated from the inner surface of the piece-shaped portion (synonymous with the "groove piece") of the frame, so that the assembly jig can be smoothly attached to and detached from the frame. However, in the assembling jig of Patent Document 2, the thickness L1 (see FIG. 11) of the groove piece F2 of the frame F may differ depending on the manufacturer, and therefore there are cases where it cannot be clamped by the fixing portion. Moreover, the assembly jig disclosed in Patent Document 2 has an integrated structure that cannot be separated from each other.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an assembling jig and a connecting tool for assembling a plurality of frames smoothly and reliably.

Hereinafter, a specific embodiment of the mode for carrying out the present invention will be described.

An assembly jig 10 that is an embodiment of the present invention will be described below with reference to FIGS. 1 to 8. FIG. This assembly jig 10 is used when assembling a plurality of commercially available frames F shown in FIG. there is That is, the pair of connecting tools 14 are of a type that are attached to the guide plate 12 and the frame F, respectively. It should be noted that the assembly jig 10 may include a plurality of guide plates 12 of two or more, and a plurality of couplers 14 of three or more.

(Schematic configuration of frame F)
Here, the frame F is extruded from aluminum or the like and formed into a columnar shape with a substantially square cross section (see FIG. 11). In the frame F, an opening groove F1 opened on a plane and a wide engaging groove F3 continuous with the opening groove F1 are formed on the four surfaces. Therefore, the groove piece F2 is formed in the frame F by the opening groove F1 and the engaging groove F3, and the opening groove F1 and the engaging groove F3 are formed over the entire length in the longitudinal direction. That is, the opening groove F1 and the engaging groove F3 having substantially T-shaped end surfaces are formed on the four side surfaces of the frame F, respectively.

(Configuration of guide plate 12 in assembly jig 10)
As shown in FIGS. 1 and 3, the guide plate 12 has a substantially rectangular planar shape and is a thin metal plate. That is, the length of the guide plate 12 in the lateral direction is set to be the same as the length of the lateral direction of the frame F (see FIG. 4), and the length in the longitudinal direction is approximately twice the length in the lateral direction. is set to A guide plate 12 (see FIG. 8) detachable from the frame F is formed with a pair of long grooves 13 corresponding to the opening grooves F1 of the plurality of orthogonal frames F (see FIG. 4).

One of the long grooves 13A is set to have a length approximately three times the width L2 (see FIG. 11) of the opening groove F1 of the frame F from the center of one longitudinal end face of the guide plate 12. As shown in FIG. The other long groove 13B extends substantially centrally from one end face of the guide plate 12 in the width direction so as to correspond to the opening groove F1 in a state in which one end face of the guide plate 12 in the width direction corresponds to the side surface of the frame F (see FIG. 4). length is set. That is, the long groove 13B is cut slightly shorter than the long groove 13A.

Specifically, the long grooves 13A and 13B are formed so as to face the opening groove F1 when the guide plate 12 is mounted on a pair of frames F assembled vertically and horizontally (see FIG. 4). Further, since the long groove 13A and the long groove 13B allow an engaging body 20 (see FIGS. 6 and 7) of the connecting tool 14 to be described later to be inserted, the length in the longitudinal direction thereof is the length of the engaging body 20 in the longitudinal direction. It is set to be approximately the same as or slightly longer than the length L4 (see FIG. 2).

Furthermore, the lengths in the short direction (synonymous with "width") of the long grooves 13A and 13B are set to be the same as the width L2 (see FIG. 11) of the opening groove F1 of the frame F. In this embodiment, instead of the long groove 13A or the long groove 13B cut from the end surface of the guide plate 12, a long hole having a length that allows the engaging member 20 of the connector 14 to be inserted may be used. That is, the elongated holes are formed by opening holes in the above-described appropriate portions of the guide plate 12 .

(Structure of connecting tool 14 in assembly jig 10)
As shown in FIGS. 1 and 6, the connector 14 includes a metal screw shaft 16 having a slightly smaller diameter than the long groove 13 of the guide plate 12, and a threaded shaft 16 which is a connection shaft to the screw shaft 16 so as to be able to move up and down. an engaging body 20 (see FIG. 2) which is screwed to one end 16A of the screw shaft 16, can be inserted into the long groove 13, and engages with the engaging groove F3 of the frame F; It has an operation body 24 connected to the other end 16B of the shaft 16 via a screw 25 and a nut 26 made of metal.

As shown in FIGS. 1 and 2, the operating body 24 has a cylindrical body 24A and a pair of flanges 24B integrally formed of plastic or the like. The brim portions 24B, which are the indicator portions, are projected linearly (that is, synonymously with "radially") in the radial direction around the cylindrical body 24A. As shown in FIGS. 2 and 6, the operating body 24 has a cylindrical screw base (not shown) larger in diameter than the screw 25 and integrally molded in the cylindrical body 24A.

The nut 26 of the operating body 24 is screwed onto the screw 25, and the screw 25 is screwed into a screw hole 17B (see FIG. 6) formed in the other end 16B of the screw shaft 16. As shown in FIG. Therefore, the screw 25 and the screw hole 17B are smaller in diameter than the screw shaft 16, and the operation body 24 is connected and fixed to the screw shaft 16 by fastening the nut 26 to the other end 16B of the screw shaft 16.

On the other hand, the engaging body 20 is integrally formed of metal, and as shown in FIGS. Prepare. The engaging portion 22 may have a shape slightly smaller than the shape of the end surface forming the engaging groove F3 of the frame F (see the dashed line in FIG. 6). A threaded hole (not shown) is formed in the engaging member 20, and this threaded hole is engaged with a threaded portion 17A formed at one end 16A of the screw shaft 16 (see FIG. 7).

The engagement member 20 is set so that its length in the lateral direction is slightly shorter than the lateral width L2 of the opening groove F1 of the frame F (see FIG. 6), It is set to be slightly longer than the width L3 (see FIG. 7) of the matching groove F3. Therefore, the pair of engaging surfaces 20A (see FIG. 2) of the engaging portion 22 face the rear surfaces of the thin pieces F2 of the frame F when the engaging portion 22 is inserted into the engaging portion F3 of the frame F. (see FIG. 7).

Moreover, the base end portion 21 has lengths and widths perpendicular to its thickness direction (vertical direction in FIG. 6) that are slightly shorter than the width L2 of the opening groove F1 of the frame F. As shown in FIG. Therefore, as shown in FIG. 6, the state in which the base end portion 21 is inserted into the opening groove F1 of the frame F is set so that the base end portion 21 is not caught in the opening groove F1. The proximal end portion 21 is formed with a tapered portion (not shown) for smooth rotation of the connector 14 when the opening groove F1 is inserted. Further, the engaging portion 22 may be chamfered at four corners such as the tip portion of the engaging surface 20A in order to prevent the engaging portion 22 from being caught, which will be described later.

As shown in FIGS. 2 and 6, the nut body (synonymous with the “pressing body”) 18 includes an operating portion 19A having a non-slip knurling process formed on the outer periphery thereof, and a smaller diameter than the operating portion 19A. The pressing portion 19B is integrally molded. The diameter of the pressing portion 19B is substantially the same as the length L4 (see FIG. 2) between the edges of the pair of engaging surfaces 20A formed on the engaging portion 22 described above.

That is, as shown in FIG. 7, when the engaging surface 20A of the engaging portion 22 faces the rear surface of the thin piece F2 of the frame F, the nut body 18 is rotated clockwise and lowered to press the pressing portion 19B of the nut body 18. The guide plate 12 and the engaging surface 20A of the engaging portion 22, which are interposed therebetween, press and hold the thin piece F2. Therefore, the coupler 14 is attached to the frame F via the guide plate 12, as shown in FIGS.

As shown in FIGS. 2 and 6, the coupler 14 extends toward the front end (hereinafter referred to as "engaging surface 20A") of the engaging body 20 formed so as to face and engage the rear surface of the engaging groove F3 of the frame F. The operation body 24 is set so as to be the same as the extending direction of the flange portion 24B, which is the index portion, so as to indicate the direction of the union 20". That is, in this embodiment, when the nut 26 is fastened and fixed to the screw shaft 16, the flange portion 24B direction of the operating body 24 is aligned with the tips of the engaging surfaces 20A of the engaging body 20 (hereinafter referred to as the "tips of the engaging body 20"). (also called) direction.

This positioning can be set arbitrarily. For example, the direction of the flange portion 24B may be positioned perpendicular to the direction of the engaging surface 20A. Further, in the present invention, an arrow may be pasted or stamped on the outer peripheral surface or the top surface of the cylindrical body 24A of the operating body 24, or the nut 26 may be painted with red ink or the like. good. Furthermore, in the present embodiment, the means for fixing the engaging member 20 and the operating member 24 to the screw shaft 16 is screwed. Also good.

(Action of this embodiment)
For example, a procedure for fixing a pair of frames F, which are vertically and horizontally assembled as shown in FIG. 3, with hexagon socket bolts BB via brackets B as shown in FIG. 17 will be described in sequence. For example, in the initial setting state of the assembly jig 10 shown in FIG. This initial set state is a set state for loss prevention so that the coupler 14 and the guide plate 12 in this embodiment are not separated from each other.

(Assembly work by assembly jig 10)
First, the nut body 18 is rotated in the loosening direction (counterclockwise direction) from the initial set state, and the pair of connecting members 14 are removed from the guide plate 12 respectively. 3, the guide plate 12 is placed on the frame F so that the long grooves 13 (synonymous with "13A or 13B") face the opening grooves F1 between the frames F (see FIG. 3). 4). Next, one connecting member 14 is inserted and set from above the frame F and the guide plate 12 so that the direction of the engaging member 20 corresponds to the long groove 13 and the open groove F1, respectively, as indicated by the arrow in FIG. See Figure 5).

In this case, the distance between the lower surface of the pressing portion 19B of the nut body 18 and the engaging surface 22A of the engaging body 20 is longer than the thickness L1 of the guide plate 12 and the groove F2 of the frame F shown in FIG. Rotate (ie, "raise") the nut body 18 in a counterclockwise direction. As for the insertion direction of the engaging portion 22, the connecting member 14 may be inserted from above toward the long groove 13 and the opening groove F1, or the engaging portion 22 may be inserted from the side toward the opening groove F1. It may be inserted into the long groove 13 of the guide plate 12 and the opening groove F1 of the frame F while moving into the inside and into the engaging groove F3.

Further, the engaging portion 22 may be inserted in a state in which the direction of the engaging body 20 corresponds to the width L3 of the engaging groove F3 of the frame F (see FIG. 7). That is, in this embodiment, the engaging portion 22 is inserted into the engaging groove F3 along the long groove 13 and the opening groove F1 of the guide plate 12 formed with the same lateral width L2 (see FIG. 6) as the opening groove F1. (See FIG. 6), the opening groove F1 serves as a guide (that is, synonymous with the "guide groove"), and the attachment of the connector 14 to the frame F can be performed smoothly and reliably.

For example, when the insertion of the engaging portion 22 is the same as the horizontal width L2 of the opening groove F1 as shown in FIG. 24B is rotated about 90 degrees. This rotation causes the entire coupling 14 to rotate about 90 degrees, so that the engaging portion 22 rotates about 90 degrees within the engaging groove F3 of the frame F (see the dashed line in FIG. 7). That is, the engaging surface 20A of the engaging portion 22 corresponding to the opening groove F1 of the frame F faces the rear surface of the groove piece F2 of the frame F. As shown in FIG. Further, the tip of the engaging member 20 is caught by the side wall of the engaging groove F3 of the frame F or the like.

After that, when the nut body 18 is rotated clockwise, the engaging body 20 rises as shown by the dashed line in FIG. The guide plate 12 and the grooved piece F2 of the frame F are pressed and sandwiched. Subsequently, in this embodiment, the other connector 14 is similarly attached to the frame F, and the attachment of the pair of connectors 14 is completed.

That is, according to this embodiment, after the guide plate 12 is placed on the frame F, the pair of connecting members 14 are attached one by one to the guide plate 12 and the frame F, respectively. improve sexuality. After that, as shown in FIG. 5, a bracket B for connecting a pair of frames F assembled vertically and horizontally is fixed via a pair of hexagon socket bolts BB and a nut (not shown) fitted into the engagement groove F3 of the frame F. (See FIG. 8). The hexagonal bolt BB is fastened using a commercially available hexagonal wrench (not shown).

(Removal work of assembly jig 10)
First, in order to remove the connector 14 from the frame F, the nut body 18 is rotated counterclockwise. Due to this rotation, the engaging body 20, that is, the connecting member 14, descends due to its own weight, as shown by the dashed line in FIG.

When the collar portion 24B is rotated by about 90 degrees, the connector 14 is rotated by about 90 degrees, so that the engaging portion 22 is rotated by about 90 degrees within the engaging groove F3 of the frame F (see FIG. 6). At this time, for example, even if the tip portion of the engaging portion 22 bites into the groove piece F2 of the frame F or the side wall of the engaging groove F3, the rotational force of the entire connector 14 is transferred through the flange portion 24B. It directly joins the tip of the engaging portion 22 .

That is, according to this embodiment, since the rotation operation of the entire connecting member 14 becomes smooth, the engaging surface 20A of the engaging portion 22 facing the rear surface of the groove piece F2 of the frame F is replaced by the opening groove of the frame F. It can correspond to F1. Further, according to the present embodiment, since the direction of the collar portion 24B of the operating body 24 is the same as the direction of the engaging body 20, the operator can determine the direction of the tip of the engaging body 20 by visually recognizing the collar portion 24B. can be easily determined.

Further, in this embodiment, even if the tip of the engaging portion 22 of the connector 14 (see FIG. 2) or the like bites into the surface forming the engaging groove F3 of the frame F, such as the lower surface of the thin piece F2. , the engaging body 20 and the operating part 24 are connected to each other through the threaded shaft 16 so that the rotational force of the operating part 24 is directly transmitted to the engaging body 20 . That is, according to this embodiment, even if the tip of the engaging portion 22 of the connecting member 14 (see FIG. 2) bites into the lower surface of the thin piece F2 of the frame F, the rotational force of the operating portion 24 is reduced. Since the force is directly transmitted to the engaging member 20, the coupling member 14 can be removed smoothly and quickly. Therefore, according to the present embodiment, the pair of post-mounting type connectors 14 can be attached and detached smoothly and quickly with respect to the guide plate 12 and the frame F, respectively, and usability is improved.

After removing the coupler 14, the guide plate 12 is removed from the frame F as indicated by the dashed line in FIG. As described above, the vertical and horizontal frames F are connected and fixed to each other in a state of being accurately and reliably positioned via brackets B (see FIG. 17). Subsequently, another frame F or the like is further assembled three-dimensionally between the frames F assembled as described above, and a working table, for example, is machined and completed.

As described above, the assembly jig 10 may be stored in the initial set state (the state shown in FIG. 1), or the guide plate 12 or the coupler 14 may be individually separated in a tool box (not shown) or the like (the state shown in FIG. 1). 8) may be accommodated. Also, the plurality of frames F may be assembled not only orthogonally as in this embodiment, but may also be assembled on a straight line in which a part of the frames overlaps on a plane, or may be assembled at a desired angle.

(Second embodiment of guide plate)
9, the guide plate 30 is a metal plate having a T-shaped planar shape. (see dashed line). Long grooves 31 (31A to 31C) and long holes 32 are formed in the guide plate 30 so as to correspond to the opening grooves F1 of the frame F, respectively.

That is, the long grooves 31 are respectively cut out from the end face of the guide plate 30, and the long hole 32 is formed between the pair of long grooves 31 facing each other. The long groove 31 and the long hole 32 are set to be longer than the length L4 between the ends of the engaging surface 20A of the engaging portion 22 so that the engaging body 20 (see FIG. 2) of the coupling 14 can be inserted. It is According to the second embodiment, for example, when there is an obstacle XX such as a frame as indicated by the two-dot chain line in FIG. 9, the long grooves 31A to 31C and the long hole 32, which are easy for the operator to work with, can be used. .

In the guide plate 30 of this embodiment, the pair of frames F can be connected in a straight line by using the long grooves 31B and 31C centering on the frame F arranged in the long groove 31A. In this case, three connectors 14 are used. Other effects are the same as those of the guide plate 12 of the first embodiment.

(Third embodiment of guide plate)
10, the guide plate 34 is a metal plate having an L-shaped planar shape. (see dashed line). Long grooves 35 (35A, 35B) and long grooves 36 are formed in the guide plate 34 so as to correspond to the opening grooves F1 of the frame F when placed.

That is, the long grooves 35A and 35B are cut from the end face of the guide plate 30 with the same length, and the long groove 36 is cut slightly shorter than the long groove 35 so as to face the long groove 35B. According to the third embodiment, for example, when there is an obstacle XX such as a frame as indicated by the two-dot chain line in FIG. 10, the long groove 35B or the long groove 36 is used because it is easy for the operator to work. In addition, in the third embodiment, the mounting direction of the guide plate 34 can be arbitrarily changed depending on the position of the obstacle XX. Other configurations and effects thereof are the same as those of the guide plate 12 of the first embodiment.

In addition, the guide plate in the present invention is not limited to the shape shown in FIGS. Further, in the present embodiment, the operating portion 19A of the nut body 18 may be provided with two round holes into which the above-described hexagonal wrench can be inserted, within an angular range of 180 degrees, for example. By using the hexagonal wrench, even if an obstacle XX as shown in FIG. 9 or 10 is arranged, the rotational force can be reliably transmitted to the operating portion 19A.

Furthermore, in this embodiment, the nut body 18 is formed in a two-stage cylindrical shape, and the operation portion 19A thereof has a shape in which the planar shape of the arc surface and the linear surface are vertically symmetrical (for example, the shape of the elongated hole 32 shown in FIG. 9). A shape in which a straight line is shortened) or the like may be used. Further, the present invention employs the lifting mechanism of the pressing body constituting the operating portion and the pressing portion as the screw fastening mechanism of the screw and nut of the first embodiment, and the "pressing body" of the present invention which can move up and down. It is also possible to use a toggle mechanism or the like constituted by a support body in which links such as levers, arms, and clamps (corresponding to the "pressing portion" in the first embodiment) are connected to a connecting shaft.

The frame F described above is a structural material that is generally used, but there are a wide variety of frames available on the market, such as the size and thickness of the thin piece F2 (see FIG. 11). . Then, according to the present invention, the assembly jig of the present invention is appropriately changed and applied so that frames having different shapes such as large and small sizes can be assembled with the assembly jig of the present invention.

For example, according to the present invention, a plurality of such guide plates may be stacked and used. That is, according to the assembly jig of the present invention, after the guide plate is placed on the frame, a plurality of connecting members are attached one by one to the guide plate and the frame, respectively. Its versatility is high, for example, it can be used by stacking multiple boards.
