  When an advertising board, a signboard, etc. are installed outdoors, a pillar to which the advertising board, signboard, etc. is attached is erected on the ground, and the advertising board, signboard, etc. are fixed to this pillar. Conventional advertising boards and signs have a wooden frame material and wooden crosspieces on the back side. Therefore, if the pillar is made of wood or the wooden furring is installed, the furring and the frame material such as advertising boards can be connected with screws or nails, so advertising boards etc. are installed on the pillars. can do. When installing an advertising board, etc., by using the method described above, the position at which the frame material such as the advertising board is connected to the support pillar or furring strip with screws or nails can be freely adjusted. Can be adjusted freely.

  However, when installing the advertising boards and the like by the above method, the frame materials such as the advertising boards and the pillars and furring strips are made of wood. , The connection between the two may be weakened. Then, there is a problem that an advertising board or the like may come off the pillar when a gust or a typhoon occurs.

  Therefore, in order to improve the durability of advertising boards and the like, metal members have been adopted for frame members and the like, columns, furring strips, etc. (Patent Document 1).

  In Patent Document 1, when a metal square bar provided with a groove having a C-shaped cross section having an opening extending in the axial direction is used for a pillar, a furring strip, or the like, a mounting device for an advertising board mounted in the groove is disclosed. Is disclosed. This advertising plate mounting device is a rectangular insert plate formed so that the length of its long side is longer than the opening width of the groove, and a mounting plate connected to this insert plate through a protrusion.

JP, 2005-148651, A

  However, when the advertising board or the like is fixed to the support pillar or the furring strip by the mounting tool for the advertising board of Patent Document 1, the posture of the advertising board or the like is determined by the posture of the placement board with respect to the strut or furring strip or the like. Therefore, in order to install the advertising board or the like in a predetermined posture, it is necessary to fix the installation tool for the advertising board to the support pillar or the furring strip so that the placing board has a predetermined angle.

  However, since the insertion plate attachment device of Patent Document 1 is in a state in which the insertion plate can move freely inside the groove to some extent, the insertion plate attachment device must be placed unless it is firmly held in a predetermined posture. The plate cannot be fixed at a certain angle. Moreover, when the screw is screwed in, a force is applied from the screw to change the attitude of the advertising board mounting device, so it is difficult to fix the advertising board mounting device in a predetermined attitude, which makes it difficult for the operator to do so. Is a heavy burden.

  Further, in the advertising board mounting device of Patent Document 1, the insertion plate is merely pressed against the flange-shaped portions located on both sides of the opening to fix the posture (that is, the postures of the insertion plate and the mounting plate). Therefore, when a force is applied to the advertising board or the like, the posture of the insertion board may change.

FIG.

  The attachment device of the present invention is a metal fitting that is attached to a groove having an opening, and is characterized in that it can be attached to the groove easily and stably.

  The groove to which the attachment device of the present invention is attached is a groove having an inner surface formed in a substantially C-shaped cross section. Specifically, as shown in FIG. 8, the inner surface of the groove G is an outer surface Ga, a bottom surface Gb facing the outer surface Ga, and a pair of inner surface surfaces Gc, Gd connecting the outer surface Ga and the bottom surface Gb. Are formed so as to have a substantially C-shaped cross section. That is, the groove G has a hollow space Gh surrounded by the four inner surfaces Ga to Gd, and the opening Gs that communicates the inside of the hollow space Gh with the outside is formed in the outer surface Ga. In the groove G, the pair of inner side surfaces Gc and Gd are provided so as to be parallel to each other and orthogonal to the outer surface Ga and the bottom surface Gb. The groove G having such a shape is a groove to which the attachment device of the present invention is attached.

  The pair of inner side surfaces Gc and Gd need not be orthogonal to the outer surface Ga and the bottom surface Gb as long as they are parallel to each other. However, if the pair of inner side surfaces Gc, Gd are orthogonal to the outer surface Ga and the bottom surface Gb, the attachment device of the present invention can be stably attached to the groove G.

  The member provided with the groove to which the attachment of the present invention is attached, that is, the member to which the attachment of the present invention is attached is not particularly limited. The attachment device of the present invention can be attached to any member as long as it can form the groove G as described above. For example, even with a square bar, a plate, a block-shaped member, a C-rail, or the like, the mounting device of the present invention can be mounted by providing the groove G as described above.

  The groove into which the attachment device of the present invention is attached includes both a groove formed by bending a plate-shaped member and a groove formed as a recess in the member. A gap formed when a plurality of members are combined also corresponds to a groove in this specification. That is, the outer surface Ga having the above-described opening Gs, the bottom surface Gb facing the outer surface Ga, the gap having the surface having the same structure as the pair of inner side surfaces Gc and Gd, and the outer surface Ga having the opening Gs and the pair of the above-described outer surface Ga. A gap having a surface having the same structure as the inner side surfaces Gc and Gd also corresponds to the groove in this specification.

  The application of the attachment device of the present invention is not particularly limited. For example, if the groove G as described above is provided in the frame (posts, furring strips, crosspieces, etc.) to which the advertising board is attached, it can be used as a device for fixing the advertising board to the frame. It can also be used as a tool for connecting a plurality of members to each other in fittings and toys. Furthermore, the material for the frame, fittings, toys, etc. to which the mounting device of the present invention is attached is not particularly limited. For example, a frame made of metal, plastic, carbon, or the like, a fitting, a toy, or the like can be a target to which the attachment device of the present invention is attached.

(Attachment 1 of this embodiment)
Hereinafter, the mounting fixture 1 of this embodiment will be described.
As shown in FIG. 1, FIG. 2 and FIG. 3 (A), the mounting device 1 of this embodiment includes an insertion portion 2, a mounting portion 3, and a connecting portion 4.
In addition, the material which comprises the mounting fixture 1 of this embodiment is not specifically limited. For example, the mounting fixture 1 of the present embodiment can be formed by using metal, plastic, carbon, or the like as a material.

  As shown in FIG. 1, the insertion portion 2 is formed of a plate-shaped member having a thickness smaller than the depth Dp (see FIG. 6B) of the groove G for mounting the mounting device 1. The insertion portion 2 is formed in a substantially parallelogram when viewed from the front (FIG. 1 (A)). In the insertion portion 2, the distance L1 in the long side direction between the acute-angled portions 2a and 2b, which is an acute angle, is the distance LG between the pair of inner side surfaces Gc and Gd of the groove G for attaching the attachment 1 (see FIG. 6A). ), Or a little longer than the distance LG.

  Further, the insertion portion 2 is formed such that the length L2 in the short side direction (in other words, the distance between the long sides) is shorter than the width of the opening Gs of the groove G. If the length L2 of the insertion part 2 in the short side direction is shorter than the width of the opening Gs of the groove G, the insertion part 2 can be easily inserted from the opening Gs of the groove G. However, if the insertion portion 2 can be inserted from the opening Gs of the groove G by tilting the insertion portion 2, the length L2 of the insertion portion 2 in the short side direction is not necessarily the width of the opening Gs of the groove G. Need not be shorter than

  Further, the insertion portion 2 is formed with female screw holes 2g penetrating the front and back thereof. The female screw hole 2g is a portion into which a screw, a bolt or the like is screwed. A screw, a bolt, or the like (hereinafter simply referred to as a screw BT) can be screwed into the female screw hole 2g to exert a force for fixing the insertion portion 2 in the groove G, which will be described in detail later.

  The obtuse angle portions 2c and 2d of the insertion portion 2 are preferably chamfered at the corners. That is, it is desirable that the corner is cut off by an arc or a straight line. This is because the obtuse angle portions 2c and 2d are less likely to become a resistance when the insertion portion 2 is rotated in the groove G as described later.

(Mounting part 3)
The attachment portion 3 is a portion to which a member connected to the member having the groove G is attached. The mounting portion 3 is formed in a substantially L shape by a plate-shaped member. The attachment part 3 is connected to the insertion part 2 by a connection part 4. Specifically, the vicinity of one end of the one long edge 3c of the attachment portion 3 is connected to the vicinity of the long side of the insertion portion 2 on the attachment portion side via the connection portion 4. Moreover, the mounting portion 3 is provided such that the surfaces 3a and 3b thereof are orthogonal to the mounting portion side surface 2e of the insertion portion 2.

(Connecting part 4)
As described above, the connection part 4 connects the insertion part 2 and the attachment part 3. One end of the connecting portion 4 is connected to the vicinity of one long side of the insertion portion 2, and the other end is connected to the mounting portion 3. The length L3 (distance from the insertion portion 2 to the attachment portion 3; see FIG. 1B) of this connecting portion 4 is the thickness t of the inner edge of the opening Gs of the groove G (see FIG. 6B). (See) is formed to be longer than. Moreover, the connecting portion 4 is formed so that its width and thickness are smaller than the width of the opening Gs of the groove G.

(A method of mounting the mounting device 1 of the present embodiment)
Next, a method of attaching the attachment device 1 of the present embodiment to a member having the groove G will be described.
In the following, as a representative, the case where the mounting device 1 of the present embodiment is mounted in the groove G formed in the shaft-shaped square bar P will be described. However, as long as it is a member in which the groove G is formed, a similar method is used. The mounting device 1 of this embodiment can be mounted in the groove G (that is, in the member).

  As shown in FIG. 3 (B), first, the insertion portion 2 of the attachment 1 is inserted into the groove G through the opening Gs. For example, if the length L2 of the insertion portion 2 in the short side direction is smaller than the width of the opening Gs of the groove G, the short side direction of the insertion portion 2 and the width direction of the opening Gs of the groove G are parallel to each other. If arranged, the insertion portion 2 can be inserted into the groove G through the opening Gs as it is (FIG. 4A). In this state, the insertion portion 2 can freely move along the groove G, so that the position at which the mounting tool 1 is installed can be freely adjusted.

  Since the attachment 1 is formed such that the length L3 of the connecting portion 4 is longer than the thickness t of the inner end edge of the opening Gs of the groove G, the insertion portion 2 has a space of the groove G completely. It is housed in Gh, and the connecting portion 4 is located at the position of the opening Gs.

  When the mounting device 1 is placed at a desired position, the insertion portion 2 rotates the mounting device 1 such that the long side direction is parallel to the width direction of the opening Gs of the groove G. In the case of FIG. 4 (B), the mounting fixture 1 is rotated clockwise. At this time, since the width and thickness of the connecting portion 4 of the insertion portion 2 are narrower than the width of the opening Gs of the groove G, the insertion portion 2 can be rotated without resistance.

  In the insertion portion 2, the distance L1 in the long side direction between the acute-angled portions 2a and 2b is equal to or slightly longer than the distance LG between the pair of inner side surfaces Gc and Gd of the groove G. It is provided. Therefore, when the long side direction of the insertion part 2 is parallel to the width direction of the opening Gs of the groove G or when it becomes a predetermined angle with the width direction of the opening Gs of the groove G, the insertion part 2 is formed. Both of the acute-angled portions 2a and 2b come into contact with the inner side surfaces Gc and Gd of the groove G, respectively, and the insertion portion 2 can no longer rotate (see FIG. 6). In this state, when the distance L1 is the same as the distance LG, the surfaces 3a, 3b of the mounting portion 3 are parallel to the width direction of the opening Gs of the groove G, that is, the axial direction of the square bar P. They are arranged so as to be orthogonal to each other (see FIG. 6A). When the distance L1 is slightly longer than the distance LG, the surfaces 3a and 3b of the mounting portion 3 are arranged at a predetermined angle with respect to the width direction of the opening Gs of the groove G. The angle formed by the surfaces 3a and 3b of the mounting portion 3 with respect to the width direction of the opening Gs of the groove G depends on the difference between the lengths of the distance L1 and the distance LG.

  When the insertion portion 2 cannot rotate, the screw BT is screwed into the screw hole 2g of the insertion portion 2 and the screw BT is screwed in (FIGS. 5A and 5B). Although the screw BT moves forward with respect to the insertion portion 3 while rotating, if the tip of the screw BT contacts the bottom surface Gb of the groove G, the screw BT cannot move forward, and therefore the force for screwing the screw BT rotates the insertion portion 2. The force is applied to the insertion portion 2. However, as described above, since the insertion portion 2 is in the non-rotatable state, the insertion portion 2 moves along the axial direction of the screw BT, and the mounting portion side surface 2e makes surface contact with the outer surface Ga of the groove G. (This state is called a fixed posture) (see FIG. 5B). If the screw BT is further screwed in from that state, the contact surface pressure between the mounting portion side surface 2e of the insertion portion 2 and the outer surface Ga of the groove G increases, and the insertion portion 2 is fixed in the groove G (FIG. )).

  As described above, in the mounting tool 1 of the present embodiment, after inserting the insertion portion 2 in the groove G and arranging it at a desired position, the insertion portion 2 is rotated in the groove G and the screw BT is screwed into the screw hole 2g. The insertion portion 2 can be fixed to the groove G simply by screwing the screws BT together. That is, the mounting tool 1 can be fixed to the square member P provided with the groove G.

  Moreover, when the insertion portion 2 rotates until the long side direction becomes parallel to the width direction of the opening Gs of the groove G (or until it reaches a predetermined angle), it cannot rotate any more. Therefore, if the long side direction of the insertion part 2 and the surfaces 3a, 3b of the mounting part 3 are adjusted to be parallel or at a predetermined angle, even if the screw BT is screwed in, the surfaces 3a, 3b of the mounting part 3 are not grooved. It is maintained parallel to the width direction of the opening Gs of G (that is, in a state orthogonal to the axial direction of the square member P) or at a predetermined angle with respect to the width direction of the opening Gs of the groove G. That is, if the insertion part 2 is fixed to the groove G, the attachment part 3 can be automatically adjusted to a predetermined angle or a predetermined posture with respect to the square bar P. Therefore, in the mounting device 1 of the present embodiment, it is not necessary for a person to hold the mounting device 1 (or the burden thereof is reduced) in order to adjust the posture of the mounting portion 3 when fixing the mounting device 1 to the timber P. The work of fixing the mounting tool 1 to the timber P becomes easy.

  Moreover, in the mounting device 1 of the present embodiment, both the acute angle portions 2a and 2b of the insertion portion 2 are fixed in a state of being in contact with the inner side surfaces Gc and Gd of the groove G, respectively. Then, in addition to the contact surface pressure between the mounting portion side surface 2e and the outer surface Ga of the groove G due to the screwing of the screw BT, the contact surface pressure between the acute angle portions 2a and 2b and the inner side surfaces Gc and Gd of the groove G is also used. Then, the insertion part 2 can be fixed to the groove. Therefore, the attachment 1 can be firmly fixed to the square P.

  In particular, when the force applied to the mounting fixture 1 via the mounting portion 3 acts so as to rotate both acute-angled portions 2a and 2b of the insertion portion 2 against the inner side surfaces Gc and Gd of the groove G, The force works so that the force for fixing the insertion portion 2 in the groove G becomes stronger. Therefore, the mounting tool 1 can stably fix the square member P.

  For example, when the mounting device 1 according to the present embodiment is used as a device for fixing an advertising board to a support post or the like, the mounting device 1 is mounted on the support post and the advertising board or the frame of the advertising board (FIG. 6) is attached to the mounting portion 3. The code F) is attached. In this case, the mounting fixture 1 is installed so that the load of the advertising board is applied to the mounting portion 3 from above. Then, the insertion portion 2 has a force such that both of the acute-angled portions 2a and 2b of the insertion portion 2 are constantly rotated by the load of the advertising plate in the direction of pressing against the inner side surfaces Gc and Gd of the groove G (see FIG. (See the arrow)) can be added, so that the mounting tool 1 is maintained in a state of being stably fixed to the square member P.

  Further, it is desirable that the rotation direction when screwing the screw BT is the same as the rotation direction in which both the acute angle portions 2a and 2b of the insertion portion 2 are pressed against the inner side surfaces Gc and Gd of the groove G. In this case, by screwing the screw BT, the rotational force can be applied as a force to press both the acute angle portions 2a and 2b of the insertion portion 2 against the inner side surfaces Gc and Gd of the groove G. Moreover, with such a configuration, after inserting the insertion portion 2 into the groove G, the insertion portion 2 rotates when the screw BT is screwed in without rotating the insertion portion 2. That is, the insertion portion 2 can be arranged so that both the acute angle portions 2a and 2b are automatically pressed against the inner side surfaces Gc and Gd of the groove G simply by screwing the screw BT.

  In the above example, the force (screw fixing force) for screwing the screw BT to bring the mounting portion side surface 2 of the insertion portion 2 into surface contact with the outer surface Ga of the groove G is mainly used as the force for fixing the insertion portion 2 in the groove G. Described when to use. However, the force (load fixing force) applied to the mounting fixture 1 via the mounting portion 3 acts so as to rotate both acute-angled portions 2a and 2b of the insertion portion 2 in the direction of pressing the inner side surfaces Gc and Gd of the groove G. In that case, the insertion portion 2 may be fixed to the groove G only by the force. However, in order to stably fix the attachment device 1 to the square bar P, it is preferable to fix the insertion portion 2 in the groove G by both the screw fixing force and the load fixing force.

(About connection part 4)
The position at which one end of the connecting portion 4 is connected to the inserting portion 2 is not particularly limited, but the connecting portion 4 may be the connecting portion 4 in the right side view of the mounting device 1 of the present embodiment (see FIG. 1A). It is better not to be located outside the long side of. This is because the connecting portion 4 is less likely to get in the way when the insertion portion 2 is inserted into the opening Gs of the groove G.

(When providing a plurality of insertion parts 2)
In the above example, the case where the attachment device 1 according to the present embodiment includes only one insertion portion 2 has been described, but a plurality of insertion portions 2 may be provided (FIGS. 7 to 11). Then, the plurality of members can be connected via the mounting portion 3 only by inserting and fixing the respective insertion portions 2 into the respective grooves of the member provided with the groove G. Then, when a plurality of members are connected by such a method, it is possible to freely release the connection of the plurality of members. Further, by adjusting the position where the insertion portion 2 is fixed in the groove G of each member, the relative arrangement of the plurality of members can be freely adjusted.

  For example, as shown in FIGS. 7 and 8, the insertion portions 2 are provided at both axial ends of the L-shaped attachment portion 3. Then, the insertion portion 2 is provided such that the mounting portion side surface 2e thereof is parallel to the surface 3a of the end portion of the mounting portion 3 to which each insertion portion 2 is connected. Then, if each insert 2 is connected to the two square members P in which the groove G is formed, the two square members P can be connected so as to be orthogonal to each other (in an L shape). Moreover, if the positions for fixing the respective insertion portions 2 are adjusted, the two square members P can be connected in a T shape. Of course, the mounting portion 3 is bent at a predetermined angle, and it is also possible to connect the two square members P to the angle of the mounting portion 3.

  Further, as shown in FIG. 9A, the insertion portions 2 are provided at different side ends of both end portions in the axial direction of the L-shaped mounting portion 3. Then, one insertion portion 2A is provided so as to be parallel to the surface 3a of the end portion of the mounting portion 3 to which the mounting portion side surface 2e is connected. Further, one insertion portion 2B is provided so as to be orthogonal to the surface 3a of the end portion of the mounting portion 3 to which the mounting portion side surface 2e is connected. Then, the insertion portions 2A and 2B can be connected as shown in FIG. 9 (B).

(Regarding the positioning unit 10)
As described above, when the acute-angled corner portions 2a and 2b of the insertion portion 2 contact the pair of side surfaces Gc and Gd of the groove G, the insertion portion 2 cannot move in the width direction of the opening Gs of the groove G. Then, it is fixed at a predetermined angle. However, if the positioning portion 10 as described below is provided, the mounting fixture 1 can be more stably fixed to the groove G at a predetermined angle.

For example, the positioning unit 10 can have a structure as shown in FIGS. 1 and 2.
As shown in FIGS. 1 and 2, a pair of protrusions 11 and 11 of the positioning portion 10 are provided on the mounting portion side surface 2e of the insertion portion 2. The pair of protrusions 11 and 11 are arranged side by side on a diagonal line connecting the acute-angled corner portions 2a and 2b of the insertion portion 2, and the distance between the outer ends thereof (that is, in the long side direction of the insertion portion 2). The length) is set to be the same as the width of the opening Gs of the groove G.
If the pair of protrusions 11 and 11 of the positioning portion 10 are provided in this way, when the long side direction rotates until it becomes parallel to the width direction of the opening Gs of the groove G, it cannot rotate any more. Therefore, if the long side direction of the insertion portion 2 and the surfaces 3a and 3b of the mounting portion 3 are adjusted to be parallel to each other, even if the screw BT is screwed in, the surfaces 3a and 3b of the mounting portion 3 will have the openings Gs of the groove G. Is maintained in parallel to the width direction of (i.e., in a state orthogonal to the axial direction of the square bar P).

  If such a positioning portion 10 is provided, the pair of protrusions 11 and 11 are arranged in the opening Gs of the groove G when the mounting fixture 1 is in the fixed posture (see FIG. 6). Then, since the outer ends of the pair of protrusions 11, 11 are in contact with the inner ends of the openings Gs of the groove G, the pair of protrusions 11, 11 form grooves in both the acute-angled portions 2a, 2b of the insertion portion 2. It can be used as a resistance when the insertion portion 2 rotates in the rotation direction in which it is pressed against the inner side surfaces Gc and Gd of G.

  In addition, the pair of protrusions 11 and 11 are arranged such that the line connecting the two is rotated to the diagonal side connecting the corners 2a and 2b having an acute angle of the insertion part 2 with respect to the long side of the insertion part 2. It should be provided side by side. In this case, if the angle formed by the line connecting the two projections 11, 11 and the diagonal line is adjusted, when the screw BT is screwed in, the surfaces 3a, 3b of the mounting portion 3 are aligned with the opening Gs of the groove G. It can be maintained at a desired angle with respect to the width direction.

  Note that the distance L5 between the outer ends of the pair of protrusions 11, 11 means that the width of the opening Gs of the groove G is the same, and that the distance L5 is completely the same, and the width of the opening Gs of the groove G is a pair. This is a concept including both the case where the distance between the outer ends of the protrusions 11 and 11 is slightly longer than L5.

  Further, in the above example, the case where the pair of protrusions 11, 11 is provided as the positioning portion 10 has been described. However, the positioning portion 10 may be provided so as to contact the inner end of the opening Gs of the groove G and fix the insertion portion 2 at a predetermined angle when the mounting fixture 1 is in the fixed posture. For example, if a linear protrusion extending along a diagonal line connecting the acute-angled corners 2a and 2b of the insertion portion 2 is provided and the length thereof is adjusted, the rotation of the insertion portion 2 is fixed at a predetermined angle. be able to.

  The method of forming the positioning portion 10 as described above is not particularly limited. For example, the insertion portion 2 may be formed later by a method such as spot welding, or when the positioning portion 10 is pressed, the insertion portion 2 may be recessed.

  Further, if the positioning portion 10 is formed as described below, it is possible to prevent the mounting fixture 1 of the present embodiment from floating from the groove G or the like when the Biz BT is screwed.

  As shown in FIGS. 12A and 12B, a pair of protrusions 11 and 11 of the positioning portion 10 are provided on the mounting portion side surface 2e of the insertion portion 2, and the distance between the inner ends in the long side direction ( That is, the length of the insertion portion 2 in the long side direction) is set to be longer than the width of the opening Gs of the groove G. That is, the pair of protrusions 11 and 11 is provided below the outer surface Ga when both the acute-angled portions 2a and 2b of the insertion portion 2 contact the inner side surfaces Gc and Gd of the groove G. The distance from the bottom surface 2f of the insertion portion 2 to the tips of the pair of protrusions 11, 11 (the surfaces of the pair of protrusions 11, 11 of the positioning portion 10) is slightly smaller than the depth Dp of the groove (for example, Keep it short (several tens of μm).

  With such a configuration, even if the screw BT is screwed in, the insertion portion 2 hardly moves along the axial direction of the screw BT. Then, in the case of the mounting portion 3 having the structure as shown in FIGS. 7 and 8, the distance from the surface 3b of the mounting portion 3 to the bottom surface 2f of the insertion portion 2 is set from the bottom surface Gb of the groove G to the surface of the square bar P. If the distance (thickness t of inner end + depth Dp) is set to be substantially the same, the surface 3b does not float above the surface of the square bar P. That is, the mounting fixture 1 of the present embodiment can be fixed to the square bar P in a state where the surface 3b of the mounting portion 3 is in close contact with the surface of the square bar P.

  If the mounting portion 3 is prevented from rising, the surface 3b of the mounting portion 3 may be slightly inclined with respect to the mounting portion side surface 2e of the insertion portion 2 (see FIG. 12C. )reference). In this case, when the screw BT is screwed in, the insertion portion 2 moves along the axial direction of the screw BT, but the attachment tool 1 tilts with the movement. Therefore, if the inclination of the surface 3b of the mounting portion 3 with respect to the mounting portion side surface 2e of the insertion portion 2 is adjusted, when the screw BT is screwed in, the surface 3b of the mounting portion 3 is brought into close contact with the surface of the square bar P. The mounting fixture 1 of the present embodiment can be fixed to the groove G.

(About the manufacturing of the attachment 1)
In the mounting tool 1 of this embodiment, the insertion portion 2, the mounting portion 3, and the connecting portion 4 may be formed by welding separately formed members or connecting them by bolts or the like. However, it is desirable to form the insertion portion 2, the attachment portion 3, and the connection portion 4 from a single plate material. For example, the mounting fixture 1 can be formed by punching and bending a single plate. If formed by such a method, no extra members or protrusions can be formed on the mounting device 1, so that the structure of the mounting device 1 can be simplified. Moreover, since the number of manufacturing steps can be reduced, manufacturing is facilitated and cost can be reduced.

  Further, when the mounting tool 1 is formed by punching and bending, the mounting tool 1 having various shapes can be formed only by changing the punching shape and the bending amount (see FIGS. 1 and 7 to 11). .

(Mounting tool 1B of another embodiment)
In the above example, the case where both the acute-angled portions 2a and 2b of the insertion portion 2 are pressed against the inner side surfaces Gc and Gd of the groove G to fix the rotation of the insertion portion 2 has been described.
However, as shown in FIGS. 10 and 11, the short sides of the insertion portion 2 may be in surface contact with the inner side surfaces Gc and Gd of the groove G, respectively, and the rotation of the insertion portion 2 may be fixed. Even in this case, if the insertion part 2 is put into the groove G from the opening Gs of the groove G and the insertion part 2 is rotated, the attachment device 1B is fixed at a predetermined angle with respect to the axial direction of the opening Gs of the groove G. The advantage is that you can.
