The best mode for carrying out the present invention will be described below with reference to the drawings.
First, the first and second plate materials to be fixed (temporarily fixed) using the clamping device 1 according to the present invention will be described. As shown in FIG. 1, the first and second plate materials A and B are all rectangular. It is formed in a flat plate shape. In particular, in this embodiment, the first and second plate materials A and B are formed in the same shape. The first and second plate materials A and B may be formed in different shapes.

  As for 1st and 2nd board | plate materials A and B, one side surface A2 along the longitudinal direction of 1st board | plate material A is a surface contact state to the front surface B1 of 2nd board | plate material B so that those front surfaces A1 and B1 may cross | intersect at right angle. It is pressed by. In addition, the first and second plate materials A and B are such that the back surface A3 of the first plate material A and one side surface B2 of the second plate material B are located on the same plane, and one end surfaces of the first and second plate materials A and B. A4 and B4 and the other end surfaces A5 and B5 are arranged on the same plane. The left and right ends of the first and second plate members A and B arranged in this way are temporarily fixed to each other by the two clamping devices 1 and 2 according to the present invention. The temporarily fixed first and second plate members A and B are fixed to each other by a nail, a wood screw or the like. A nail, a wood screw, etc. penetrate the 2nd board | plate material B from the back surface B3, and are inserted in the 1st board | plate material A from the one side surface A2.

  The angle formed by the first and second plate members A and B is not necessarily a right angle. For example, the angle formed by the first and second plate members A and B may be an acute angle or an obtuse angle by making the angle of the one side surface A2 with respect to the front surface A1 an acute angle or an obtuse angle. Further, the first and second plate materials A and B may be crossed in a “T” shape without crossing in a bowl shape. Further, the one end surfaces A4, B4 and the other end surfaces A5, B5 of the first and second plate members A, B may be positioned on different planes.

  Next, a plate material clamping device 1 for temporarily fixing the first and second plate materials A and B in the above arrangement state will be described. In this embodiment, two clamping devices 1 and 1 are used. However, the clamping device 1 disposed on the left side in FIG. 1 will be described, and the clamping device 1 disposed on the right side will be described on the left side. The same components as those of the arranged clamping device 1 are denoted by the same reference numerals, and the description thereof is omitted. Here, since the direction of the clamping device 1 arranged on the right side is 180 ° different from that of the clamping device 1 arranged on the left side, the clamping device 1 is arranged in a point-symmetrical state with respect to the left clamping device 1. It should be noted that. Moreover, about the clamp apparatus 1, the top and bottom, right and left shown in FIG. 1, and front and back may be used for the convenience of the description. Of course, the clamping device 1 is not limited to such a direction.

  The clamp device 1 includes an apparatus body 2, a first fixing means 3, a second fixing means 4, a first mounting mechanism 5 and a second mounting mechanism 6.

  The apparatus main body 2 is made of a metal plate material, and is formed by bending a flat metal plate at a right angle. Therefore, the apparatus main body 2 has a first plate portion 21 and a second plate portion 22 that are orthogonal to each other. The back surfaces of the first and second plate portions 21 and 22 are pressed against the front surfaces A1 and B1 of the first and second plate materials A and B in a surface contact state, respectively. Thereby, the angle which the 1st and 2nd board | plate materials A and B make is maintained at the predetermined angle, ie, a right angle. As is clear from this, the back surface of the first plate portion 21 is a first reference surface 21a, and the back surface of the second plate portion 22 is a second reference surface 22a. Here, the entire back surface of the first plate portion 21 is the first reference surface 21a. However, a part of the back surface of the first plate portion 21 may be recessed and only the remaining portion may be used as the first reference surface. For example, the central portion of the back surface of the first plate portion 21 may be recessed, and only the peripheral edge portion forming an annular shape may be used as the first reference surface. The same applies to the second reference surface 22a.

  A first positioning piece 21b is formed integrally with the left end portion of the first plate portion 21 so as to protrude downward at a right angle. One end face A4 of the first plate A is pressed against the first positioning piece 21b. Thereby, the 1st board | plate material A is positioned in the left-right direction. The protruding amount of the first positioning piece 21b is set to a value smaller than the plate thickness of the first plate A. Therefore, the tip of the first positioning piece 21b does not protrude downward from the back surface A3 of the first plate A. Depending on the positional relationship between the first plate portion 21 and the first plate material A, another positioning piece may be formed at the front end portion of the first plate portion 21 instead of or together with the first positioning piece 21b. .

  A second positioning piece 22b that protrudes at a right angle toward the rear is formed integrally with the left end of the second plate portion 22. One end face B4 of the second plate B is pressed against the second positioning piece 22b. Thereby, positioning of the 2nd board | plate material B in the left-right direction is made | formed. The protrusion amount of the second positioning piece 22b is set to a value smaller than the thickness of the second plate material B. Therefore, the tip of the second positioning piece 22b does not protrude rearward from the back surface B3 of the second plate B. Depending on the positional relationship between the second plate portion 22 and the first plate material A, another positioning piece may be formed at the upper end of the second plate portion 22 instead of or together with the second positioning piece 22b. .

  The first and second plate members A and B positioned as described above with respect to the apparatus main body 2 are temporarily fixed to the apparatus main body 1 by the first and second fixing means 3 and 4.

  As shown in FIG. 2, the first fixing means 3 uses a commercially available clip. However, it is not always necessary to use a commercially available clip, and any clip having the following configuration may be used. That is, the first fixing means 3 has a pair of rotating pieces 31 and 32. The pair of rotating pieces 31 and 32 are arranged to face each other in the vertical direction. The left and right intermediate portions of the rotating pieces 31 and 32 are rotatably connected by a shaft 33 extending horizontally in the front-rear direction. Therefore, when the left end portions of the rotating pieces 31 and 32 are moved toward and away from each other, the right end portions of the rotating pieces 31 and 32 are moved away from each other and moved closer to each other. The left end portions of the rotating pieces 31 and 32 are first and second operation portions 31a and 32a, respectively, and the right end portions of the rotating pieces 31 and 32 are respectively first and second holding portions 31b and 32b. The 1st and 2nd clamping parts 31b and 32b can be moved apart until it becomes wider than the total thickness of the 1st board | plate material A and the 1st board part 21. FIG.

  A torsion coil spring 34 (first urging means; only a part thereof is shown in FIG. 2) is externally attached to the shaft 33. By the torsion coil spring 34, the rotating pieces 31, 32 are urged to rotate so that the first and second holding portions 31b, 32b approach each other. Therefore, after the first and second holding members 31b and 32b are moved away from each other against the urging force of the torsion coil spring 34, the first plate member A and the left end portion of the first plate portion 21 are inserted therebetween. Then, when the rotating pieces 31 and 32 can be freely rotated, the first and second clamping portions 31b and 32b are moved closer by the torsion coil spring 34, and the first plate member A and the first plate portion are moved. 21 is sandwiched. Accordingly, the left end portion of the first plate material A is temporarily fixed to the first plate portion 21.

  The second fixing means 4 has the same configuration as the first fixing means 3, and corresponds to the rotating pieces 31 and 32, the shaft 33 and the torsion coil spring 34 of the first fixing means 3. 41, 42, a shaft 43, and a torsion coil spring (second biasing means) 44. Third and fourth operation portions 41a and 42a corresponding to the first and second operation portions 31a and 32a of the first fixing means 3 are formed at the left end portions of the rotating pieces 41 and 42, respectively. Third and fourth sandwiching portions 41b and 42b corresponding to the first and second sandwiching portions 31b and 32b of the first fixing means 3 are formed at the right end portions of the rotating pieces 41 and 42, respectively. However, since the 2nd fixing means 4 clamps the 2nd board | plate material B and the 2nd board part 22, it arrange | positions in the state which orient | assigned the longitudinal direction of the axis | shaft 43 to the up-down direction. Of course, the 3rd and 4th clamping parts 41b and 42b can move apart until the 2nd board | plate material B and the 2nd board part 22 can be inserted between them. After the third and fourth sandwiching portions 41b and 42b are moved away from each other, the second plate member B and the second plate portion 22 are inserted therebetween. When the rotating pieces 41 and 42 can be freely rotated, the third and fourth clamping portions 41b and b2b are moved closer to each other by the torsion coil spring 44, and the second plate member B and the second plate portion are moved. 22 is sandwiched. Accordingly, the second plate material B is temporarily fixed to the second plate portion 22.

  The first clamping portion 31 b of the rotating piece 31 of the first fixing means 3 is detachably fixed to the first plate portion 21 by the first mounting mechanism 5. The first mounting mechanism 5 has a first clamping member (first mounting member) 51. The 1st clamping member 51 is arrange | positioned facing the upper surface (surface which faces the direction opposite to the 1st reference surface 21a) of the 2nd board part 21. As shown in FIG. In particular, the left end portion of the first clamping member 51 is opposed to the first clamping portion 31b.

As shown in FIG. 2, a screw shaft 52 is erected and fixed on the upper surface of the second plate portion 21 with its longitudinal direction directed in the vertical direction. The screw shaft 52 penetrates the right end portion of the first clamping member 51 and projects upward. A nut 53 is screwed to the upper end portion of the screw shaft 52 penetrating the first clamping member 51. When the nut 53 is screwed and moved downward, the first clamping member 51 is pressed downward by the nut 53, and the left end portion of the first clamping member 51 is pressed against the first clamping portion 31b. As a result, the first clamping part 31 b is pressed against the upper surface of the second plate part 21. As a result, the first clamping part 31 b is fixed to the first plate part 21. On the other hand, when the nut 53 is loosened, the pressing and fixing of the first clamping part 31 b to the first plate part 21 by the first clamping member 51 is released, and the first clamping part 31 b can be detached from the first plate part 21. Thus, the 1st clamping part 31b is attached to the 1st board part 21 so that attachment or detachment is possible. As apparent from the above contents, the screw shaft 52 and the nut 53 constitute a first screw mechanism.

When the nut 53 is loosened greatly, the first clamping part 31b can be detached from the first plate part 21 to the left and the front. However, when the nut 53 is slightly loosened, the first holding part 31b is only forward. It is possible to leave. This is because a concave portion 51a extending in the front-rear direction is formed at the left end portion of the clamping member 51, and the first clamping portion 31b is engaged with the concave portion 51a. When the nut 53 is loosened greatly, the first sandwiching portion 31b is pulled out downward from the recess 51a, so that the first sandwiching portion 31b can be detached from the recess 51a in either the left direction or the front direction. On the other hand, if the nut is slightly loosened, the first clamping portion 31b is maintained in a state in which the first clamping portion 31b is engaged with the recess 51a so as not to move leftward. For this reason, the 1st clamping part 31b is detachable only to the front with respect to the recessed part 51a.

  The third clamping part 41 b of the rotating piece 41 of the second fixing means 4 is detachably fixed to the second plate part 22 by the second mounting mechanism 6. The second mounting mechanism 6 is configured in the same manner as the first mounting mechanism 5. Therefore, the second mounting mechanism 6 includes a clamping member 61, a screw shaft 62, and a nut 63 corresponding to the clamping member 51, the screw shaft 52, and the nut 53 of the first mounting mechanism 5. The screw shaft 62 and the nut 63 constitute a second screw mechanism. Further, a recess 61 a is formed at the left end portion of the clamping member 61.

Here, the 2nd mounting mechanism 6 fixes the 3rd clamping part 41b of the 2nd fixing means 4 to the 2nd board part 22 so that attachment or detachment is possible. For this purpose, the clamping member 61 is disposed to face the front surface of the second plate portion 22 (the surface facing the front in FIG. 1) and the third clamping portion 41b, and the screw shaft 62 is disposed on the front surface of the second plate portion 22. It is fixed upright in the horizontal direction. When the nut 63 screwed to the screw shaft 62 is tightened, the left end portion of the clamping member 61 presses and fixes the third clamping portion 41 b to the second plate portion 22. When the nut 63 is loosened, the third clamping part 41b can be detached from the second plate part 22. Of course, when the nut 63 is loosened greatly, the third clamping part 41b can be detached from the second plate part 22 in both the left and upper directions, and when the nut 63 is slightly loosened, The third clamping part 41b can be detached only upward.

  As described above, the first fixing means 3 fixes the left end portion of the first plate material A to the first plate portion 21, and the second fixing means 4 fixes the left end portion of the second plate material B to the second plate portion 21. Thus, the left end portions of the first and second plate members A and B are fixed via the apparatus main body 2. On the other hand, for the right end portions of the first and second plate members A and B, the first fixing means 3 fixes the right end portion of the second plate member B to the first plate portion 21 and the second fixing means 4 is the first plate member. By fixing the right end portion of A to the second plate portion 22, the right end portions of the first and second plate members A and B are fixed to each other via the apparatus main body 2.

Next, an example of a method for fixing the first and second plate materials A and B using the clamping devices 1 and 1 having the above-described configuration will be described.
In fixing, first, as shown in FIG. 3, the left and right ends of the first plate A and the clamping devices 1 and 1 are opposed to each other in the left-right direction. At this time, it is desirable to remove the first fixing means 3 from the first plate portion 21 for the right clamping device 1.

Next, the left clamp device 1 is moved to the right relative to the first plate A. If the 1st board | plate material A approaches the 1st fixing means 3, the 1st and 2nd clamping members 31b and 32b of the 1st fixing means 3 will be spaced apart. And the left end part of the 1st board | plate material A is inserted between the 1st board part 21 and the 2nd clamping part 32b. At this time, by bringing the first reference surface 21a into contact with the first plate material A, the first plate material A can be easily inserted between the first plate portion 21 and the second clamping portion 32b. The first plate A is inserted between the first plate portion 21 and the second clamping portion 32b until it abuts against the first positioning piece 21b. Thereafter, the first and second holding portions 31 b and 32 b are moved closer to each other by the torsion coil spring 34. Actually, since the first clamping part 31b is fixed to the first plate part 21, the second clamping part 32b moves closer to the first clamping part 31b (first plate part 21). As a result, the first and second sandwiching portions 31 b and 32 b sandwich the first plate member A and the first plate portion 21. Accordingly, the left end portion of the first plate material A is fixed to the first plate portion 21 of the clamping device 1. The first plate A is adjusted in the front-rear direction before the first plate A is fixed, and one side A2 of the first plate A is positioned on the same plane as the second reference surface 22a.

  It is also possible to insert the left end portion of the first plate A between the first plate portion 21 and the second clamping portion 32b by moving the clamp device 1 in the front-rear direction. However, the first plate A is finally positioned in the left-right direction by pressing the first plate A against the first positioning piece 21b. At that time, the clamping device 1 is moved to the right with respect to the first plate A. Moved to. Therefore, when inserting the first plate material A between the second clamping portion 32b and the first plate portion 21, it is desirable to move the clamping device 1 in the left-right direction. Note that the right end portion of the first plate A can be fixed to the second plate portion 22 of the right clamp device 1 in the same manner as the left clamp device 1. However, in this case, the right end portion of the first plate material A is fixed to the second plate portion 22 by the second fixing means 4.

  Next, as shown in FIG. 4, the 2nd board | plate material B is arrange | positioned above the clamp apparatuses 1 and 1. As shown in FIG. Then, the second plate member B is moved downward relative to the clamping devices 1 and 1, and between the second positioning piece 22 b of the left clamping device 1 and the first positioning method 21 b of the right clamping device 1. Get in. Thereafter, the third and fourth holding portions 31 b and 32 b of the second fixing means 4 are moved away from each other, and the left end portion of the second plate member B is inserted between the fourth holding portion 32 b and the second plate portion 22. On the other hand, it is only necessary to move the right end portion of the second plate member downward along the first reference surface 21a. This is because the first fixing means 3 of the right clamping device 1 is detached from the device main body 2. In addition, the 2nd board | plate material B is moved below until the one side surface B2 is located on the same plane as the back surface A3 of the 1st board | plate material A. As shown in FIG.

  Here, assuming that the first fixing means 3 is attached to the right clamping apparatus 1, the first fixing means 3 of the right clamping apparatus 1 is obstructive when the second plate member B is moved downward. Become. Of course, during the downward movement of the second plate material B, the third and second clamping portions 41b and 42b of the second fixing means 4 of the left clamp device 1 are separated from each other, and at the same time, the first clamp device 1 of the right clamp device 1 is separated. If the 1st and 2nd clamping parts 31b and 32b of the fixing means 3 are spaced apart, the both right and left both ends of the 2nd board | plate material B can be inserted among them. However, when the first plate member B is moved downward, the second fixing means 4 of the left clamping device 1 and the first fixing means 3 of the right clamping device 1 are both separated at the same time. It is difficult for workers. Therefore, the first fixing means 3 of the right clamping device 1 is removed in advance. Of course, if the second and first fixing means 4 and 3 of both clamping devices 1 and 1 can be operated simultaneously, the first fixing means 3 of the right clamping device 1 is attached to the apparatus body 2 in advance. May be. Alternatively, the first fixing means 3 of the right clamping device 1 may be attached to the first plate portion 21 and the second fixing means 4 of the left clamping device 1 may be removed from the second plate portion 22 in advance.

  The left end portion of the second plate member B can be inserted between the second sandwiching portion 32b and the second plate portion 22 by relatively moving the second plate member B to the left. In that case, in order that the 2nd board | plate material B may not interfere with the 1st positioning piece 21b of the clamp apparatus 1 on the right side so that the right end part of the 2nd board | plate material B may be located back from a left end part. It is slightly inclined with respect to the first reference surface 21a. Since this inclination angle is small, there is no hindrance when the second plate member B is moved to the left and inserted between the second sandwiching portion 32 b and the second plate portion 22. When the left end surface of the second plate material B hits the second positioning piece 22b, the right end portion of the second plate material B is moved forward until it hits the first reference surface 21a.

  Thereafter, as shown in FIG. 5, the first fixing means 3 of the right clamping device 1 is positioned above the first plate portion 21. Then, the first fixing means 3 is moved downward. If the 1st fixing means 3 approaches the 2nd board | plate material B, the 1st and 2nd clamping parts 31b and 32b will be moved apart, and the 2nd board | plate material B and the 1st board part 21 will be inserted among them. At the same time, the first clamping part 32 b is inserted between the first plate part 21 and the clamping member 51. If the 1st clamping part 32b is inserted to a predetermined position, the 1st and 2nd clamping parts 31b and 32b will be moved close and the 2nd board | plate material B and the 1st board part 21 will be clamped. Thereby, the left end part of the 2nd board part B is fixed to the 1st board part 21 of the clamp apparatus 1 of the right side. Thereafter, the nut 53 is tightened to fix the first clamping part 32 b to the first plate part 21.

  In this way, the left end portions of the first and second plate members A and B are fixed by the left clamp device 1, and the right end portions are fixed by the right clamp device 1. As a result, the first and second plate members A and B are fixed (temporarily fixed) to each other via the left and right clamping devices 1 and 1. Therefore, the subsequent main fixing operation can be easily performed.

  After the first and second plate members A and B are permanently fixed, the left and right first and second clamp devices 1 and 1 are detached from the first and second plate members A and B. The clamp device 1 on the left side releases the fixed state of the first and second fixing means 3 and 4. And it can remove from the 1st and 2nd board | plate materials A and B by moving to the left, maintaining the state. The right clamping device 1 can be detached from the first and second plate members A and B by moving to the right while maintaining the state in which the first and second fixing means 3 and 4 are released.

  According to the clamp device 1 having the above-described configuration, the first plate member A (second plate member B) is held together with the device main body 2 by the first fixing unit 3 (second fixing unit 4), whereby the first and second plates are clamped. Since the plate materials A and B are fixed to the apparatus main body 1, when the first and second plate materials A and B are fixed to the apparatus main body 1, the first and second sandwiching portions 31b and 32b (third and third) are fixed. The four clamping parts 41b and 42b) need only be moved apart and moved closer together. Therefore, the efficiency of the fixing operation can be greatly improved as compared with the conventional clamping device that needs to rotate the male screw member many times.

In particular, in the clamping device 1 of this embodiment, since a commercially available clip is used as the first and second fixing means 3 and 4, the manufacturing cost of the clamping device 1 can be suppressed at a low cost. Moreover, since the 1st clamping parts 31b and 41b of the 1st and 2nd fixing means 3 and 4 are attached to the apparatus main body 2 so that attachment or detachment is possible, in the state which attached the 1st clamping parts 31b and 41b to the apparatus main body 2 By doing so, the first and second fixing means 3 and 4 can be handled integrally with the apparatus main body 1. Therefore, the clamping operation of the first and second plate materials A and B can be efficiently performed. On the other hand, by removing the 1st fixing means 3 or the 2nd fixing means 4 from the apparatus main body 2, between the 1st and 2nd clamping parts 31b and 32b or between the 3rd and 4th clamping parts 41b and 42b. The 1st board | plate material A or the 2nd board | plate material B can be inserted easily.

  FIG. 6 shows another example of the first fixing means used in the plate clamping apparatus according to the present invention. 1st fixing means 3 'of this example is marketed as a double clip, and has the main-body part 35 which makes a cross-section substantially triangle. The main body portion 35 is made of a metal such as spring steel, and a pair of pivots projecting in the same direction from the spring plate portion (first urging means) 35a and both widthwise end portions of the spring plate portion 35a. It has plate parts 35b and 35c. The rotating plate portions 35b and 35c are inclined so as to approach each other as they are separated from the spring plate portion 35a. The tip portions of the rotating plate portions 35b and 35c are pressed against each other by the elastic force of the spring plate portion 35a. The tip portions of the rotating plate portions 35b and 35c pressed against each other are first and second clamping portions (third and fourth clamping portions) 35d and 35e, respectively. The first and second sandwiching portions 35d and 35e can be moved away from each other when the spring plate portion 35a is elastically deformed, and until the first plate member A and the first plate portion 21 can be inserted therebetween. It is possible to move away.

  Operation shafts 36 and 37 are connected to the distal end portions of the rotating plate portions 35b and 35c, respectively. The operation shafts 36 and 37 are formed by bending a metal bar such as steel, and are formed in a substantially U shape. Both end portions of the operation shaft 36 are coupled to the tip end portion of the rotating plate portion 35b so as to be rotatable about an axis parallel to the longitudinal direction of the spring plate portion 35a. An intermediate portion of the operation shaft 36 is brought into contact with an intersecting portion between the spring plate portion 35a and the rotating plate portion 35b. Similarly, both ends of the operating shaft 37 are rotatably connected to the tip of the rotating plate portion 35c, and an intermediate portion of the operating shaft 37 is an intersection of the spring plate portion 35a and the rotating plate portion 35c. Is contacted. When the curved first and second operation portions 36a and 37a of the operation shafts 36 and 37 are moved closer to each other, the spring plate portion 35a is elastically deformed so that the first and second holding portions 35d and 35e are separated from each other. Moved. When the rotating plate portions 35b and 35c are in a state where they can be freely moved, the first and second clamping portions 35d and 35e are moved closer to each other by the elastic force of the spring plate portion 35a.

  The 1st fixing means 3 'of the said structure can be used as a 2nd fixing means as it is.

The present invention is not limited to the above-described embodiment, and various modifications can be employed without departing from the scope of the invention.
For example, in the above embodiment, since the first and second plate materials A and B to be fixed are long, their both ends are fixed by the two clamping devices 1 and 1, but the first And when the 2nd board | plate materials A and B are short length, you may fix the 1st and 2nd board | plate materials A and B with the single clamp apparatus 1 only.
Further, as described in Patent Document 1 and other patent publications, the apparatus main body 2 can also be variously modified. The positional relationship between the apparatus main body 2 and the first and second fixing means 3 and 4 can be variously modified. For example, in the above-described embodiment, the first fixing means 3 uses the axis of the shaft 33 that is the rotation center of the first and second holding portions 31b and 32b as the short direction of the first and second plate members A and B ( The first fixing means 3 may be arranged with the axis of the shaft 33 directed in the longitudinal direction of the first and second plate members A and B. That is, the posture of the first fixing means 3 may be changed by 90 °. The same applies to the second fixing means 4.
Furthermore, in the above-described embodiment, the first and third holding portions 31b and 32b are detachably fixed to the apparatus main body 2. However, the first and third holding portions 31b and 32b are attached to the apparatus main body 2. It may be fixed in a non-detachable manner by welding or other means.
