  The present invention relates to an attachment device.

  When installing an advertising board or a signboard outdoors, a post for attaching the advertising board or the signboard is erected on the ground, and the advertising board or the signboard is fixed to the post. Conventional advertising boards and signboards are provided with wooden frame members and wooden crosspieces on the back. For this reason, if the pillar is made of wood or the wooden trunk edge is erected, the frame edge such as the advertising board can be connected to the trunk edge with screws, nails, etc. can do. And when installing the advertising board etc. by the above method, the position where the frame material such as the advertising board and the column and the trunk edge can be freely adjusted by screws or nails, so the installation position of the advertising board etc. Can be adjusted freely.

  However, when installing advertising boards etc. by the above method, since the frame materials such as the advertising boards and the pillars and trunk edges are wooden, if the frame materials etc. and the pillars and trunk edges etc. corrode due to aging, etc. The connection between the two may be weakened. Then, when a gust or typhoon occurs, there exists a problem that an advertising board etc. will remove | deviate from a support | pillar.

  Therefore, in order to improve the durability of the advertising board or the like, a metal member is employed for a frame member, a column, a trunk edge, or the like (Patent Document 1).

  In Patent Document 1, when a metal square member provided with a groove having a C-shaped cross section having an opening extending along the axial direction is used for a column, a trunk edge, or the like, an advertising board mounting device attached to the groove Is disclosed. This advertising board mounting tool is an insertion plate that is rectangular and has a long side longer than the opening width of the groove, and a mounting plate that is connected to the insertion plate via a protrusion. And. If the long side of the mounting plate is arranged so as to be parallel to the width direction of the groove, the surface of the mounting plate is provided so as to be parallel to the width direction of the groove. The advertising board mounting device is also provided with a vertical plate provided parallel to the insertion plate, and a screw hole is formed in the vertical plate.

  However, when the advertisement board or the like is fixed to the column or the trunk edge by the advertisement board mounting device of Patent Document 1, the attitude of the advertisement board or the like is determined by the attitude of the mounting plate with respect to the column or the trunk edge. Therefore, in order to install the advertising board or the like in a predetermined posture, it is necessary to fix the advertising board mounting tool to the column or the trunk edge so that the mounting board has a predetermined angle.

  However, the advertisement board mounting device of Patent Document 1 is placed in a state where the insertion board can move freely within the groove to some extent. The plate cannot be fixed at a predetermined angle. Moreover, when a screw is screwed in, a force is applied to change the posture of the billboard mounting device from the screw. Therefore, it is difficult to fix the billboard mounting device in a predetermined posture. The burden of is great.

  Further, in the advertising board mounting device of Patent Document 1, the posture (that is, the posture of the insertion plate or the mounting plate) is simply fixed by pressing the insertion plate against the flange-like portions located on both sides of the opening. Therefore, when force is applied to the advertising board or the like, the posture of the insertion board may change.

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

  The groove to which the fixture 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 groove G has an inner surface that is an outer surface Ga, a bottom surface Gb facing the outer surface Ga, and a pair of inner side surfaces Gc and Gd that connect 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 four inner surfaces Ga to Gd, and an opening Gs that connects the inside of the hollow space Gh and 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 | channel G which has such a shape is a groove | channel in which the fixture of this invention is attached.

  Note that the pair of inner side surfaces Gc and Gd do not necessarily have to 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 and 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.

  A member provided with a groove to which the attachment device of the present invention is attached, that is, a member to which the attachment device of the present invention is attached is not particularly limited. Any member that can provide the groove G as described above can attach the attachment device of the present invention. For example, a square member, a plate member, a block-like member, a C rail, or the like can be attached to the attachment device of the present invention by providing the groove G as described above.

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

  The use of the fixture of the present invention is not particularly limited. For example, if a groove G as described above is provided in a frame (post, trunk edge, crosspiece, etc.) to which an advertising board is attached, it can be used as a device for fixing the advertising board to the frame. Moreover, it can be used also as an instrument which connects several members in a fitting, a toy, etc. Furthermore, materials such as a frame, a joinery, and a toy to which the attachment device of the present invention is attached are not particularly limited. For example, a frame, a joinery, a toy or the like formed using metal, plastic, carbon, or the like as a material can be a target to which the attachment device of the present invention is attached.

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

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

  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 in the short side direction of the insertion portion 2 is shorter than the width of the opening Gs of the groove G, the insertion portion 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 in the short side direction of the insertion portion 2 is not necessarily the width of the opening Gs of the groove G. It does not have to be shorter.

  Further, the insertion portion 2 is formed with a female screw hole 2g penetrating the front and back. 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) is screwed into the female screw hole 2g to exert a force for fixing the insertion portion 2 to the groove G. Details will be described later.

  The obtuse corners 2c and 2d of the insertion portion 2 are preferably chamfered at the corners. In other words, 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 resistance when the insertion portion 2 is rotated in the groove G as will be described later.

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

(Connecting part 4)
As described above, the connecting portion 4 connects the insertion portion 2 and the attachment portion 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 connecting portion 4 has a length L3 (distance from the insertion portion 2 to the attachment portion 3, see FIG. 1B), and a thickness t (FIG. 6B) of the inner edge of the opening Gs of the groove G. It is formed to be longer than (see). Moreover, the connecting portion 4 is formed such that the width and thickness thereof are narrower than the width of the opening Gs of the groove G.

(Attachment method of the fixture 1 of this embodiment)
Next, a method for attaching the attachment device 1 of the present embodiment to a member having the groove G will be described.
Below, as a representative, the case where the mounting fixture 1 of this embodiment is attached to the groove G formed in the shaft-shaped square member P will be described. The attachment device 1 of this embodiment can be attached to the groove G (that is, to the member).

  As shown in FIG. 3 (B), first, the insertion portion 2 of the fixture 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 narrower 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. If it arrange | positions, the insertion part 2 can be put into the groove | channel G through the opening Gs as it is (FIG. 4 (A)). In this state, since the insertion portion 2 can freely move along the groove G, the position where the attachment device 1 is installed can be freely adjusted.

  In addition, since the attachment tool 1 is formed so 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 is completely in the space of the groove G. It is accommodated in Gh and the connection part 4 comes to be located in the position of opening Gs.

  When the fixture 1 is arranged at a desired position, the insertion portion 2 rotates the fixture 1 so that the long side direction is parallel to the width direction of the opening Gs of the groove G. If it is Drawing 4 (B), fixture 1 will be rotated clockwise. At this time, since the width and thickness of the connecting portion 4 are narrower than the width of the opening Gs of the groove G, the inserting portion 2 can be rotated without resistance.

  The insertion portion 2 is such that the distance L1 in the long side direction between the acute angle portions 2a and 2b is the same length as the distance LG between the pair of inner side surfaces Gc and Gd of the groove G or slightly longer than the distance LG. Is provided. Therefore, when the long side direction of the insertion portion 2 is parallel to the width direction of the opening Gs of the groove G, or when a predetermined angle is formed with the width direction of the opening Gs of the groove G, the insertion portion 2 is inserted. Both the acute angle 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 cannot be rotated any more (see FIG. 6). In this state, when the distance L1 is the same length as the distance LG, the surfaces 3a and 3b of the attachment portion 3 are parallel to the width direction of the opening Gs of the groove G, that is, the axial direction of the square member P. It arrange | positions so that it may orthogonally cross (refer FIG. 6 (A)). When the distance L1 is slightly longer than the distance LG, the surfaces 3a and 3b of the attachment 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 is determined according to the difference in length between 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 (FIGS. 5A and 5B). The screw BT advances with respect to the insertion portion 3 while rotating. However, when the tip of the screw BT comes into contact with the bottom surface Gb of the groove G, the screw BT cannot move forward, so that the force for screwing the screw BT rotates the insertion portion 2. The force is applied to the insertion portion 2 as a force. However, as described above, since the insertion portion 2 is in a state where it cannot rotate, the insertion portion 2 moves along the axial direction of the screw BT, and the attachment portion side surface 2e is in surface contact with the outer surface Ga of the groove G. (This state is referred to as a fixed posture) (see FIG. 5B). If the screw BT is further screwed in from this 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 to the groove G (FIG. 5B )).

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

  In addition, when the insertion portion 2 rotates until the long side direction is parallel to the width direction of the opening Gs of the groove G (or until a predetermined angle is reached), the insertion portion 2 cannot rotate any more. Therefore, if the long side direction of the insertion portion 2 and the surfaces 3a and 3b of the attachment portion 3 are adjusted to be parallel or at a predetermined angle, the surfaces 3a and 3b of the attachment portion 3 are grooved even if the screw BT is screwed. It is maintained parallel to the width direction of the G opening Gs (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 portion 2 is fixed to the groove G, the attachment portion 3 can be automatically adjusted to a predetermined angle or a predetermined posture with respect to the square member P. Therefore, in the mounting device 1 of the present embodiment, it is not necessary for a person to hold the mounting device 1 in order to match the posture of the mounting portion 3 when fixing to the square member P (or the burden is reduced). The operation of fixing the fixture 1 to the square member P becomes easy.

  In addition, in the attachment device 1 of the present embodiment, both the acute angle portions 2a and 2b of the insertion portion 2 are fixed 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 screwing of the screw BT, the contact surface pressure between the acute angle portions 2a and 2b and the inner surfaces Gc and Gd of the groove G is also used. And the insertion part 2 can be fixed to a groove | channel. Therefore, the fixture 1 can be firmly fixed to the square member P.

  In particular, when the force applied to the attachment device 1 via the attachment portion 3 acts to rotate both acute angle portions 2a and 2b of the insertion portion 2 against the inner side surfaces Gc and Gd of the groove G, The force acts so as to increase the force for fixing the insertion portion 2 to the groove G. Therefore, the bracket 1 can be stably fixed to the fixture 1.

  For example, when the mounting device 1 of the present embodiment is used as a device for fixing an advertising board to a column or the like, the mounting device 1 is attached to the column and the frame or the like of the advertising plate or the advertising board is attached to the mounting portion 3 (FIG. 6). 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, a force is applied to the insertion portion 2 such that the acute angle portions 2a and 2b of the insertion portion 2 always rotate in a direction of pressing against the inner side surfaces Gc and Gd of the groove G due to the load of the advertising board (FIG. 6A). )), The fixture 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 for pressing the acute angle portions 2a and 2b of the insertion portion 2 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 that presses 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 part 2 into the groove G, the insertion part 2 rotates when the screw BT is screwed in without rotating the insertion part 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 to the groove G. Explained when to use. However, the force (load fixing force) applied to the attachment device 1 via the attachment portion 3 acts so as to rotate both the acute angle portions 2a and 2b of the insertion portion 2 in the direction of pressing against the inner side surfaces Gc and Gd of the groove G. When doing so, you may make it fix the insertion part 2 to the groove | channel G only with the force. However, in order to stably fix the attachment device 1 to the square member P, it is preferable to fix the insertion portion 2 to the groove G with both the screw fixing force and the load fixing force.

(About connecting part 4)
In addition, although the position which connects the one end part of the connection part 4 to the insertion part 2 is not specifically limited, When the attachment instrument 1 of this embodiment is a right side view (refer FIG. 1 (A)), the connection part 4 is the insertion part 2. It is better to provide it so that it is not located outside than the long side. This is to prevent the connecting portion 4 from getting in the way when the insertion portion 2 is inserted into the opening Gs of the groove G.

(When providing a plurality of insertion portions 2)
In the above example, the case where the attachment device 1 of 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, a plurality of members can be connected via the attachment portion 3 only by inserting and fixing each insertion portion 2 into each groove of the member provided with the groove G. And when a some member is connected by this method, connection release of a plurality of members can be made free. Moreover, if the position which fixes the insertion part 2 in the groove | channel G of each member is adjusted, the relative arrangement | positioning of a some member can also be adjusted freely.

  For example, as shown in FIGS. 7 and 8, the insertion portions 2 are respectively provided at both ends in the axial direction of the L-shaped attachment portion 3. And the insertion part 2 is provided so that the attachment part side surface 2e may become parallel to the surface 3a of the edge part of the attachment part 3 to which each insertion part 2 is connected. Then, if each insertion part 2 is connected to the two square members P in which the groove | channel G was formed, the two square members P can be connected so that it may mutually orthogonally cross (L shape). And if the position which fixes each insertion part 2 is adjusted, the two square members P can also be connected in T shape. Of course, the attachment portion 3 is bent at a predetermined angle, and the two square members P can be connected to the angle of the attachment portion 3.

  Moreover, as shown to FIG. 9 (A), the insertion part 2 is each provided in the side edge from which the both ends of the axial direction of the L-shaped attachment part 3 differ. And one insertion part 2A is provided so that it may become parallel to the surface 3a of the edge part of the attaching part 3 to which the attaching part side surface 2e is connected. Moreover, one insertion part 2B is provided so that the surface 3a of the edge part of the attachment part 3 with which the attachment part side surface 2e is connected may be orthogonally crossed. Then, each insertion part 2A, 2B can be connected as shown in FIG. 9 (B).

(About the positioning unit 10)
As described above, if the corners 2 a and 2 b that are the acute angle of the insertion portion 2 come into contact with 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. And fixed at a predetermined angle. However, if the positioning part 10 which will be described later is provided, the 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.
As shown in FIGS. 1 and 2, a pair of protrusions 11, 11 of the positioning portion 10 are provided on the mounting portion side surface 2 e of the insertion portion 2. The pair of protrusions 11 and 11 are provided side by side on a diagonal line connecting the corners 2a and 2b that are the acute angle 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). (Length) is provided to be the same length as the width of the opening Gs of the groove G.
If the pair of protrusions 11, 11 of the positioning portion 10 are provided in this way, if 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 attachment portion 3 are adjusted to be parallel, the surfaces 3a and 3b of the attachment portion 3 are open to the opening Gs of the groove G even if the screw BT is screwed. It is maintained in parallel with the width direction (that is, a state orthogonal to the axial direction of the square member P).

  When the positioning portion 10 is provided, the pair of protrusions 11 and 11 are disposed in the opening Gs of the groove G when the mounting tool 1 is in a fixed posture (see FIG. 6). Then, since the outer ends of the pair of projections 11 and 11 are in contact with the inner end of the opening Gs of the groove G, the pair of projections 11 and 11 groove both the acute angle portions 2a and 2b of the insertion portion 2. It can be set as the resistance at the time of the insertion part 2 rotating in the rotation direction pressed against the inner surfaces Gc and Gd of G.

  In addition, the pair of protrusions 11, 11 are in a state where the line connecting them is rotated to the diagonal line connecting the corners 2 a, 2 b that are the acute angle of the insertion part 2 with respect to the long side of the insertion part 2. It only has to be provided side by side. In this case, if the angle formed between the pair of protrusions 11 and 11 and the diagonal line is adjusted, when the screw BT is screwed, the surfaces 3a and 3b of the mounting portion 3 are formed on 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 and 11 is the same length as the width of the opening Gs of the groove G, and the case where both are completely the same length and the width of the opening Gs of the groove G is a pair. This is a concept including both cases where the distance L5 between the outer ends of the protrusions 11 and 11 is slightly longer than the distance L5.

  In the above example, the case where the pair of protrusions 11 and 11 are provided as the positioning portion 10 has been described. However, the positioning portion 10 only needs to be provided so as to be in contact with the inner end of the opening Gs of the groove G and fix the insertion portion 2 at a predetermined angle when the mounting tool 1 is set in a fixed posture. For example, if a linear protrusion extending along a diagonal line connecting the corners 2a and 2b that are the acute angle 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 for forming the positioning part 10 as described above is not particularly limited. For example, the insertion portion 2 can be formed later by a method such as spot welding, or when the positioning portion 10 is pressed, the insertion portion 2 can be recessed.

  Moreover, if the positioning part 10 is formed as follows, when the Biz BT is screwed in, it is possible to prevent the fixture 1 of the present embodiment from floating from the groove G or the like.

  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 provided to be longer than the width of the opening Gs of the groove G. That is, when both the acute angle portions 2a and 2b of the insertion portion 2 are in contact with the inner side surfaces Gc and Gd of the groove G, the pair of protrusions 11 and 11 are provided so as to be positioned below the outer surface Ga. The distance from the bottom surface 2f of the insertion portion 2 to the tips of the pair of protrusions 11 and 11 (the surfaces of the pair of protrusions 11 and 11 of the positioning portion 10) is slightly smaller than the depth Dp of the groove (for example, (Several tens of μm).

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

  In order to prevent the attachment portion 3 from being lifted, the surface 3b of the attachment portion 3 may be slightly inclined with respect to the attachment portion side surface 2e of the insertion portion 2 (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. Therefore, if the inclination of the surface 3b of the attachment portion 3 with respect to the attachment portion-side surface 2e of the insertion portion 2 is adjusted, the screw 3 is screwed and the surface 3b of the attachment portion 3 is in close contact with the surface of the square member P. The fixture 1 of this embodiment can be fixed to the groove G.

(About the manufacture of the fixture 1)
In the attachment device 1 of the present embodiment, the insertion portion 2, the attachment portion 3, and the connecting portion 4 may be formed by welding separately formed members or connecting them with bolts or the like. However, it is desirable to form the insertion portion 2, the attachment portion 3, and the connecting portion 4 from a single plate material. For example, the fixture 1 can be formed by punching and bending a single plate. If it forms by this method, since the attachment tool 1 cannot have an extra member, a protrusion, etc., the structure of the attachment tool 1 can be simplified. In addition, since the number of manufacturing steps can be reduced, manufacturing is facilitated and costs can be reduced.

  Moreover, when forming the fixture 1 by punching and bending, the fixture 1 of various shapes can be formed only by changing the punching shape and the bending amount (see FIGS. 1 and 7 to 11). .

(Mounting device 1B according to another embodiment)
In the above example, the case where 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 to fix the rotation of the insertion portion 2 has been described.
However, as shown in FIGS. 10 and 11, the short side of the insertion portion 2 may come into surface contact with the inner side surfaces Gc and Gd of the groove G to fix the rotation of the insertion portion 2. Even in this case, if the insertion portion 2 is inserted into the groove G from the opening Gs of the groove G and the insertion portion 2 is rotated, the fixture 1B is fixed at a predetermined angle with respect to the axial direction of the opening Gs of the groove G. The advantage that it can be obtained.

  The mounting device of the present invention is suitable for a fixing device used when fixing an advertising board to a column or the like, or a device for connecting or fixing a frame, a joinery, a toy or the like.
