Description

  The present invention relates to a tool holder and a tool holding method. The tool holder is an article for directly holding a tool, such as a shelf board, and is used as a part in a tool storage device or the like.

The tool storage device is a device for safely storing various metal cutting tools used in machine tools such as lathes, milling machines, drilling machines, so-called tools, in a machine factory or the like in a state convenient for reuse.
As shown in FIG. 1 (a), a tool generally includes a blade portion P for cutting metal at one end, and a shank portion Q for attaching to a machine tool at the other end. A disc portion R is provided between the shank portion Q and the shank portion Q.

  The shape and structure of the blade portion P vary greatly depending on the purpose of cutting. Further, the tool has various shapes other than the blade portion. For example, as shown in FIG. 1B, there is a case in which a chuck portion S is provided between the blade portion P and the disc portion R to increase the height. Furthermore, the chuck portion S has various heights, and there are a chuck portion S having a large height as shown in FIG. Moreover, the outer diameter of each part changes with the magnitude | sizes of a tool. Therefore, the tool will take about a hundred shapes.

  However, the tool also includes a portion that is the same shape as a part of the tool. For example, the shank portion Q has a truncated cone shape having the same apex angle, and a female screw hole X for inserting an implantation bolt is attached to the tip. Further, the disc portion R protrudes greatly in the direction perpendicular to the axis of the tool, and the upper and lower surfaces U thereof are all annular planes, and a circular groove W extending on the outer periphery of the disc portion R is provided. Is formed. In addition, between the tools having the same outer diameter of the disc portion R, the width and depth of the annular groove W are equal to each other.

In addition, the tool is a unit in which each of the above parts is made of special steel. Therefore, the tool is heavy, and even a small tool has a weight of several kilograms. Therefore, a large force is required for handling. In addition, the blade portion P has a sharp blade edge, and is easily damaged when the blade edge touches a hard object, and cannot be used when the blade edge is damaged. Therefore, careful handling is required.
The tool storage device must be able to store a heavy tool with almost 100 shapes as described above easily and safely so that it does not damage the blade and is convenient for reuse. I must.

  To store the tool, a tool holder that directly holds the tool is required. Many tool holders that have been used so far are, for example, those described in JP-A-10-29176. As shown in FIG. 2, the tool holder uses truncated cone-shaped synthetic resin cylinders G and H, the shank part Q of the tool is placed in this cylinder, and the tool disk part R In many cases, circular planes U on the upper and lower sides are overlapped with the cylinder ridges, and on the other hand, a circular notch is provided on the shelf, and the cylinder ridges are placed in the notches to hold the tool. In this case, since the tool is only on the shelf, when the shelf is shaken, the tool falls or falls.

  A shelf board has also been proposed in which the tool does not fall easily even if the shelf board vibrates. This is described in JP-A-11-58269. As shown in FIG. 3, this shelf board is made by fitting a tool holder body 3 made of synthetic resin on both sides of a flat metal member 2 and fixing with bolts 8.

  The tool holder body 3 is provided with a concave groove 4 for accommodating a tool, and the tool disk portion R is inserted into the concave groove 4 to hold the tool. In this case, a locking portion 7 is provided in the recessed groove 4 so that the locking portion 7 enters the outer circumferential groove W (the locking groove 6 in FIG. 3) of the tool disk portion. Therefore, even if a shelf board vibrates, a tool cannot fall easily.

However, since the tool holder body 3 is supposed to be made of synthetic resin, various disadvantages are caused. First, a molding die is required to make the synthetic resin. However, since this molding die becomes large, molding is not easy. Next, when a synthetic resin molded body is subjected to a large force, it naturally has a property that it cannot be avoided that it is deformed and curved. Since the tool holder body 3 serves as a shelf for supporting the entire weight of the tool, it cannot be avoided that the tool holder body 3 is deformed and bent when receiving a large force of the tool. If the notch opening sinks due to a deformation curve, there is a risk of dropping the tool.
As described above, the conventional tool holder has a risk of dropping or dropping the tool.

JP-A-10-29176 JP-A-11-58269

  The present invention provides a tool holder that is easy to store and take out a tool, and that does not cause the tool to fall down or fall even when the tool holder vibrates. .

The method for holding a tool described in Japanese Patent Application Laid-Open No. 11-58269 is excellent in that the tool does not fall down even if the shelf board is shaken. Therefore, the present inventor tried to provide a tool holder and a tool holding method without the risk of tool dropout, following the tool holding method proposed by Japanese Patent Laid-Open No. 11-58269.
In Japanese Patent Application Laid-Open No. 11-58269, the tool holder is made of synthetic resin, so that there is a risk of tool dropping off. So to make this tool-free tool holder, you must use a sturdy material other than synthetic resin.

  Therefore, the inventor attempted to make a tool holder using a metal plate as a material. For this purpose, a metal plate shelf is provided with a notch for accommodating a tool, and an attempt has been made to provide a metal protrusion with a cross-sectional angle as proposed in Japanese Patent Application Laid-Open No. 11-58269 around the notch. However, it takes time and effort to make the metal plate a ridge as proposed in Japanese Patent Application Laid-Open No. 11-58269, and to connect the obtained ridge to a metal plate shelf, welding, etc. This approach has proved unsuitable for practical use because of the complexity of the manufacturing process as a means is required.

Thereafter, the inventor found out that it is suitable to mold with a synthetic resin to make the above-mentioned protrusion. Therefore, the inventor made an attempt to make the protrusions with a synthetic resin and attach the protrusions to a metal plate shelf. In this case, the problem is how to shape the molded body including the protrusions.
The inventor originally thought that it was convenient to make the notch of the shelf that accommodates the tool into a U shape (in other words, a horseshoe shape) with one end opened. Therefore, the inventor considered that the shape of the molded body including the ridges is U-shaped, and that the U-shaped molded body covers the edge of the shelf notch. If the synthetic resin molding covers a part of the metal shelf, the weight of the tool is supported by the metal shelf, so the shelf will drop the tool even if the synthetic resin is deformed. It is because it thought that it did not reach.

  Then, the inner surface of the U-shaped synthetic resin molding is provided with a protrusion having a mountain-shaped cross section. Further, in order to connect the U-shaped synthetic resin molded body to the shelf plate, the outer surface of the U-shaped molded body is formed as a smooth curved surface, and a groove extending in a U shape is formed on the curved surface. In this groove, the notch edge of the shelf board is inserted and connected.

  Thus, the inventor actually made a molded body having the following shape using polypropylene as a synthetic resin. In other words, it is open at one end and is a U-shaped molded body as a whole, and the inner side surface has a mountain-shaped cross section and a ridge extending in a U shape, and the outer side surface is U-shaped. A molded body having a smooth curved surface extending in a shape and having a U-shaped groove formed therein was produced.

  This formed body was attached so as to cover the notch edge of the metal plate shelf, and the tool was actually held in the notch to examine whether the formed body was deformed. As a result, it was confirmed that the formed body was not deformed, and was sufficient to hold the tool as in the conventional metal plate shelf. The present invention has been completed based on such confirmation.

The above-described shelf board can generally be said to be a support board for indicating a tool. Therefore, in this invention, what corresponds to a shelf board is called a support board.
The invention includes an invention of a tool holder and an invention of a method for holding a tool.

  The invention of the tool holder includes a support plate having a U-shaped notch that opens at one end, and a U-shaped synthetic resin molded body that covers the edge of the notch. In addition, the inner surface is provided with a protrusion with a U-shaped cross section extending in a U-shape, and the outer surface is formed into a shape with a groove extending in a U-shape toward the protrusion, Is characterized in that the notch edge of the support plate is inserted into the groove and connected to the support plate.

  The invention of the tool holding method uses a support plate made of a metal plate provided with a U-shaped notch that opens at one end, and a molded body made of a U-shaped synthetic resin that covers the edge of the notch, The molded body is provided with a ridge having a mountain-shaped cross section extending in a U-shape on the inner surface, and is formed into a shape having a groove extending in a U-shape toward the ridge on the outer surface. A notch edge of the support plate is fitted into the groove of the body to form a tool holder, and a tool disc is inserted into the notch of the tool holder to hold the tool.

  In this invention, a support plate made of a metal plate provided with a U-shaped notch that opens at one end, and a U-shaped synthetic resin-made molded body that covers the edge of the notch are used. Are connected to form a tool holder, and the tool holder has a U-shaped notch that opens at one end. Therefore, the tool can be inserted through the opening and easily locked to the tool holder. In addition, since the notch is U-shaped, the tool can be accommodated in the inner part of U, so that there is a slight distance from the accommodation position to the opening, so the tool does not easily fall out of the opening.

Further, in this invention, since the synthetic resin is used to cover the notch edge of the support plate, it is easy to mold the synthetic resin, so that the inner flange surface is provided with a ridge and the outer flange surface is provided with a groove. The covering can be easily made in a single shape. Therefore, it is easy to manufacture the tool holder.
Further, in the present invention, since the protrusions having a mountain-shaped cross section extending in a U-shape are provided on the inner surface of the molded body, the tool holder is inserted into the groove W of the tool disk portion. Therefore, the tool is held in a state where it cannot be moved up, down, left and right, and therefore the tool is securely and securely held. In addition, since the groove W of the tool disk portion is symmetric in the vertical direction, the tool holder can be used in the same manner regardless of whether the tool has the blade portion P facing up or vice versa. The tool can be held.

Furthermore, in this invention, since the groove extending in a U shape is formed on the outer side surface of the molded body, the molded body can be easily connected to the support plate by fitting the notched edge of the support plate into the groove. . Further, since the groove extending in the U-shape is directed to the ridge, the ridge is reinforced by the edge of the support plate, so that a heavy tool can be sufficiently supported.
The tool holder according to the present invention provides the above-described benefits.

On the other hand, the tool holding method according to the present invention inserts the tool disk part into the notch of the tool holder and the tool holder holds the tool, so that the held tool is in the groove W of the disk part. Since the protrusions of the formed body are inserted and held in the tool, the tool is restrained from moving in the vertical direction, the horizontal direction, and further in the front-rear direction. Therefore, the tool is safely and reliably held in the tool holder, and there is no risk of dropping off.
The method of the present invention brings about such an effect.

FIG. 4 is an exploded perspective view of the tool holder according to the present invention. FIG. 5 is a perspective view of the tool holder according to the present invention. FIG. 6 is a perspective view showing a mode in which the tool holder according to the present invention shown in FIG. 4 is used as a tool storage device by being locked to a standing wall. FIG. 7 is a front view of a tool holder according to the present invention that houses a tool. FIG. 8 is a cross-sectional view showing another use mode of the tool holder according to the present invention. FIG. 9 is a front view showing a state in which the tool holder shown in FIG. 8 holds the tool upside down. FIG. 10 is a perspective view of another tool holder according to the present invention.

  FIG. 4 shows a tool holder according to the present invention. This tool holder includes a support plate 1 made by processing a metal plate and a U-shaped molded body 2 made integrally with a synthetic resin. The support plate 1 includes a vertical piece 11 and a horizontal piece 12 connected in an L shape. The vertical piece 11 is provided with a screw hole 111 for fixing to a wall or the like.

  The horizontal piece 12 includes a U-shaped cutout 121, and the cutout 121 opens at the end of the horizontal piece 12. The width F of the notch 121 varies depending on the diameter of the tool disk R. However, since the diameter of the disc portion R is only three types called BT-30, BT-40, and BT-50, it is sufficient to prepare these three types of notches 121.

  The U-shaped molded body 2 is integrally made of a thermoplastic resin such as polypropylene. The overall shape of the molded body 2 is made so as to cover the edge of the notch 121 of the support plate 1. Therefore, the overall shape of the molded body is U-shaped. On the inner surface of the molded body 2, a protrusion 21 is formed that extends in a U shape along the inner surface. The ridges 21 are for fitting into grooves W provided on the outer periphery of the tool disc part. Therefore, the shape of the ridge 21 is made in accordance with the groove W of the tool. The cross-sectional shape of the protrusion 21 is a mountain shape, and is preferably an isosceles trapezoid.

  The outer side of the molded body 2 is a smooth curved surface that originally extends in a U-shape. A groove 22 toward the ridge 21 is formed on the outer side of the outer surface, and the groove 22 extends in a U shape along the outer surface. The groove 22 is for inserting the notched edge 124 of the support plate 1. The cross-sectional shape of the groove 22 is preferably wide at the outer side and narrow at the portion approaching the ridge 21.

  The molded body 2 shown in FIG. 4 can be easily connected to the support body 1 simply by being advanced in the arrow B direction. That is, when the molded body 2 is advanced in the direction of arrow B, the notched edge 124 of the support 1 enters the groove 22 of the molded body 2, so that the molded body 2 is moved until the notched edge 124 is completely fitted into the groove 22. The connection can be established simply by moving in the direction of arrow B.

  FIG. 5 shows a state in which the molded body 2 is connected to the support 1. In the connected state shown in FIG. 5, the cut-out edge 124 of the support 1 reaches the bottom of the groove 22 of the molded body 2, and the cut-out edge 124 enters the base of the protrusion 21 of the molded body. For this reason, the protrusion 21 is reinforced by the cutout edge 124. Therefore, the protrusion 21 has sufficient strength to support the weight of the tool.

  In FIG. 4, drooping pieces 122 are attached to both sides of the horizontal piece 12. The hanging piece 122 is attached to prevent the horizontal piece 12 from being deformed due to the weight of the tool. In FIG. 4, a hole 123 is formed in the horizontal piece 12, but the hole 123 overlaps the hole 23 of the molded body 2 when the molded body 2 is connected to the support plate 1. The molded body 2 can be fixed to the support 1 by pushing the stopper 3 from the overlapped hole 23 into the hole 123.

  The stopper 3 shown in FIG. 4 includes a head 31 that bulges at one end and a locking portion 32 that bulges elastically at the other end. Although the latching | locking part 32 is based on a cylinder, the cylinder is divided | segmented by the dividing line of the axial direction, and the cross section is formed of the several locking piece which exhibits circular arc shape. Therefore, the stopper 3 can squeeze the locking piece and push it into the hole 23. When the stopper 3 is pushed in, the stopper 3 swells in the hole 23 and the hole 123 and can serve as a fixing.

  The tool holder C shown in FIG. 6 is configured in the same manner as the tool holder shown in FIG. That is, the tool holder C is configured by connecting the molded body 2 to the holding plate 1. The holding plate 1 includes a vertical piece 11 and a horizontal piece 12, and a U-shaped notch 121 is formed in the horizontal piece 12. On the other hand, the molded body 2 is provided with a protrusion 21 on the inner side and a groove 22 on the outer side. A notch edge 124 of the support plate is fitted into the groove 22 of the molded product, and the molded product 2 is connected to the support plate 1.

  The tool holder C shown in FIG. 6 is different from the tool holder shown in FIG. 5 in that hook-shaped locking claws 112 are attached to both sides of the upper end of the vertical piece 11. The hook-shaped locking claw 112 is for locking the tool holder C in a locking hole D1 provided in the panel D serving as a standing wall. The tool holder C can be easily locked at an arbitrary position on the panel D by providing a large number of locking holes D1 having the same shape in the panel D. FIG. 6 shows how the tool holder C is used.

  FIG. 6 shows operations necessary to hold the tool A on the tool holder C. That is, the tool A is held on the tool holder C simply by placing the tool A in front of the tool holder C, moving it in the direction of arrow B, and inserting the disc portion R into the notch 121 of the tool holder C. be able to. In this way, holding the tool A on the tool holder C is very simple.

  FIG. 7 shows a state in which the tool holder C holds the tool A as described above. In FIG. 7, since the protrusion 21 of the tool holder C is fitted in the groove W of the tool A, the tool A cannot tilt in the vertical direction, the front-rear direction, or the left-right direction. Therefore, even if the tool holder C vibrates, the tool A does not fall down and therefore does not fall off from the tool holder C.

  FIG. 8 shows a state in which another tool holder C according to the present invention is locked to the panel D and used. The tool holder C in FIG. 8 includes a support plate 1 made of a metal plate and a molded body 2 made of a synthetic resin. The molded body 2 has a protrusion 21 on the inner side surface and a groove 22 on the outer side surface. Since the notch edge of the support plate 1 is inserted into the groove 22 and connected to the support plate 1, the tool holder according to the present invention is provided.

  The tool holder C in FIG. 8 differs from the tool holder in FIG. 6 in that an upward locking claw 113 is attached to the upper end of the vertical piece of the support plate 1. Since the locking claw 113 faces upward, the tool holder cannot be locked to the panel D as it is. Therefore, the fixing plate 4 provided with a new downward locking claw 141 is used to lock the panel D as follows.

  First, the downward locking claw 41 of the fixing plate 4 is inserted into the locking hole D1 of the panel D, the fixing plate 4 is locked to the panel D, and then the vertical piece 11 of the support plate is overlaid thereon, The upward locking claw 113 of the piece 11 is inserted into another locking hole D1, and then the vertical piece 11 is fixed to the fixing plate 4 and integrated, and the tool holder is locked downward with the upward locking claw 113. It fixes to the panel D with the nail | claw 41. FIG. Thus, the tool holder can be firmly fixed to the panel D. In FIG. 8, the vertical piece 11 and the fixing plate 4 are fixed by the stopper 3 shown in FIG.

  Further, FIG. 8 shows that in order for the tool holder C to keep holding the tool reliably, the held tool A slightly moves from the vertical direction to the vertical piece 11, that is, slightly toward the back of the notch. It shows that it is preferable to make it tilted. The angle of inclination is up to 10 degrees. There are various ways to do this. One is to change the thickness of the molded body so that the opening on the upper side of the notch is higher at the side and is inclined within an angle range of 0 to 10 degrees with respect to the horizontal plane. Further, the intersection angle between the vertical piece 11 and the horizontal piece 12 can be changed to an angle range of 80 to 90 degrees, or the extending direction of the vertical piece 11 can be tilted within a range from the vertical direction to an angle of 10 degrees. FIG. 8 shows an example in which the intersection angle between the horizontal piece 12 and the vertical piece 11 intersects at an angle of 80 to 90 on the assumption that the vertical piece 11 extends in the vertical direction.

  FIG. 9 is a front view of the tool holder when the tool is held by the tool holder shown in FIG. 8. In FIG. 9, since the tool A is accommodated in the tool holder C with the ridges 21 of the tool holder C inserted in the grooves W, the tool A can be moved in any direction, up and down, left and right, and front and rear. Cannot move. Therefore, even if the tool holder C vibrates, the tool A does not fall down. Moreover, it does not fall off from the tool holder C.

  The groove W of the tool A originally has an isosceles trapezoidal cross section. If the cross sectional shape of the ridge 21 is the same shape and the same size as the isosceles trapezoid of the groove W as shown in FIG. Even if A is turned upside down, the groove W can be in close contact with the protrusion 21. Therefore, even if the tool faces the blade portion P upward or vice versa, as long as the tool plate portion R is inserted into the notch, the protrusion 21 and the groove W are in close contact with each other. It will be held by the tool holder. This is shown in the drawing. That is, in FIG. 8, the tool holder holds the tool with the blade part P up, and in FIG. 9, the tool with the blade part P down is held.

  Until now, although the case where the tool holder was provided with one notch was demonstrated, the notch is not restricted to one. The tool holder of this invention can be provided with two or more notches arranged side by side on one shelf. FIG. 10 shows an example in which two tool holders are provided on a support plate 1 made of a metal plate shelf.

In FIG. 10, the support plate 1 serving as a shelf plate is composed of a vertical piece 11 and a horizontal piece 12, and the horizontal piece 12 includes two U-shaped cutouts 121, as described above, at the edge of each cutout. A tool holder is made by attaching a molded body 2 made of synthetic resin.
Further, FIG. 10 shows that the tool holder reliably holds the tool when the tool disk portion is inserted into the notch 121 regardless of whether the tool has the blade portion P facing upward or conversely. It is shown that.

  When the molded body 2 is actually made by molding a synthetic resin, if the molded body is in contact with the tool over a wide area, the tool is stably held in the molded body. As shown in FIG. 4, it is preferable to increase the thickness of the portion above the groove 22 and decrease the thickness of the portion below the groove 22. However, if injection molding is performed as it is, a “sink” (dent) is generated in the upper portion, and a good molded product cannot be obtained. In order to prevent this, as shown in the molded body 2 of FIG. 10, if a shallow small groove 6 is formed in a part of the outer peripheral surface of the upper part, a good molded body free from “sink” can be obtained. The molded body 2 shown in FIG. 10 has a groove 6 formed for this reason and is suitable for practical use.

  In general, a tool often has an upper portion and a lower portion that have different heights with the disc portion R as a boundary. Since the tool can be held regardless of whether the tool holder is directed to the lower side or the lower side, the tool can be spatially efficiently held in consideration of the state of the upper space and the lower space of the tool holder. Since the held tool is restrained from being moved by the protrusion provided on the tool holder, it can be safely and reliably held.

  The tool holder according to the present invention comprises a support plate made of a metal plate and a molded body made of a synthetic resin. A groove is formed on the outer side of the molded body, and a notch provided in the support plate in the groove. Since the support plate and the molded body are connected only by inserting the edge, the tool holder can be easily manufactured and the molded body can be easily replaced.

Further, according to the present invention, the tool disk is inserted into the notch of the tool holder and the tool is held by the tool holder, so that the outer diameter of the tool disk is 30, 40 and 50. Since these three types of cutouts are sufficient, the tool can be easily held and is economical.
Since the tool holder and the tool holding method according to the present invention have the advantages as described above, they have high practical value and can be widely used in tool storage devices, tool storage racks, storages, and the like.

  The present invention relates to a tool holder and a tool holding method. The tool holder is an article for directly holding a tool, such as a shelf board, and is used as a part in a tool storage device or the like.

The tool storage device is a device for safely storing various metal cutting tools used in machine tools such as lathes, milling machines, drilling machines, so-called tools, in a machine factory or the like in a state convenient for reuse.
As shown in FIG. 1 (a), a tool generally includes a blade portion P for cutting metal at one end, and a shank portion Q for attaching to a machine tool at the other end. A disc portion R is provided between the shank portion Q and the shank portion Q.

  The shape and structure of the blade portion P vary greatly depending on the purpose of cutting. Further, the tool has various shapes other than the blade portion. For example, as shown in FIG. 1B, there is a case in which a chuck portion S is provided between the blade portion P and the disc portion R to increase the height. Furthermore, the chuck portion S has various heights, and there are a chuck portion S having a large height as shown in FIG. Moreover, the outer diameter of each part changes with the magnitude | sizes of a tool. Therefore, the tool will take about a hundred shapes.

  However, the tool also includes a portion that is the same shape as a part of the tool. For example, the shank portion Q has a truncated cone shape having the same apex angle, and a female screw hole X for inserting an implantation bolt is attached to the tip. Further, the disc portion R protrudes greatly in the direction perpendicular to the axis of the tool, and the upper and lower surfaces U thereof are all annular planes, and a circular groove W extending on the outer periphery of the disc portion R is provided. Is formed. In addition, between the tools having the same outer diameter of the disc portion R, the width and depth of the annular groove W are equal to each other.

In addition, the tool is a unit in which each of the above parts is made of special steel. Therefore, the tool is heavy, and even a small tool has a weight of several kilograms. Therefore, a large force is required for handling. In addition, the blade portion P has a sharp blade edge, and is easily damaged when the blade edge touches a hard object, and cannot be used when the blade edge is damaged. Therefore, careful handling is required.
The tool storage device must be able to store a heavy tool with almost 100 shapes as described above easily and safely so that it does not damage the blade and is convenient for reuse. I must.

  To store the tool, a tool holder that directly holds the tool is required. Many tool holders that have been used so far are, for example, those described in JP-A-10-29176. As shown in FIG. 2, the tool holder uses truncated cone-shaped synthetic resin cylinders G and H, the shank part Q of the tool is placed in this cylinder, and the tool disk part R In many cases, circular planes U on the upper and lower sides are overlapped with the cylinder ridges, and on the other hand, a circular notch is provided on the shelf, and the cylinder ridges are placed in the notches to hold the tool. In this case, since the tool is only on the shelf, when the shelf is shaken, the tool falls or falls.

  A shelf board has also been proposed in which the tool does not fall easily even if the shelf board vibrates. This is described in JP-A-11-58269. As shown in FIG. 3, this shelf board is made by fitting a tool holder body 3 made of synthetic resin on both sides of a flat metal member 2 and fixing with bolts 8.

  The tool holder body 3 is provided with a concave groove 4 for accommodating a tool, and the tool disk portion R is inserted into the concave groove 4 to hold the tool. In this case, a locking portion 7 is provided in the recessed groove 4 so that the locking portion 7 enters the outer circumferential groove W (the locking groove 6 in FIG. 3) of the tool disk portion. Therefore, even if a shelf board vibrates, a tool cannot fall easily.

However, since the tool holder body 3 is supposed to be made of synthetic resin, various disadvantages are caused. First, a molding die is required to make the synthetic resin. However, since this molding die becomes large, molding is not easy. Next, when a synthetic resin molded body is subjected to a large force, it naturally has a property that it cannot be avoided that it is deformed and curved. Since the tool holder body 3 serves as a shelf for supporting the entire weight of the tool, it cannot be avoided that the tool holder body 3 is deformed and bent when receiving a large force of the tool. If the notch opening sinks due to a deformation curve, there is a risk of dropping the tool.
In addition, as shown in FIG. 11, in the utility model registration No. 3066827, a U-shaped hole portion 23 is provided in the horizontal portion 21, and the edge of the hole portion 23 is erected to reinforce the boss portion 24. And a tool holder for holding the tool by inserting the boss portion 24 into the groove portion 12 of the tool. However, since the boss portion 24 is merely an upright edge of the hole portion 23, the surface in contact with the tool is a curved surface having no irregularities in the standing direction, while the groove portion 12 of the tool has a cross section. Is a trapezoid whose width becomes narrower toward the bottom. Therefore, when the boss portion 24 is inserted into the groove portion 12, the boss portion 24 only touches the groove portion with a slight surface. Therefore, when the horizontal portion 21 is shaken, the tool is moved to the horizontal portion. It falls on 21 or falls from the horizontal part 21.
As described above, the conventional tool holder has a risk of dropping or dropping the tool.

JP-A-10-29176 JP-A-11-58269 Utility Model Registration No. 3066827

  The present invention provides a tool holder that is easy to store and take out a tool, and that does not cause the tool to fall down or fall even when the tool holder vibrates. .

The method for holding a tool described in Japanese Patent Application Laid-Open No. 11-58269 is excellent in that the tool does not fall down even if the shelf board is shaken. Therefore, the present inventor tried to provide a tool holder and a tool holding method without the risk of tool dropout, following the tool holding method proposed by Japanese Patent Laid-Open No. 11-58269.
In Japanese Patent Application Laid-Open No. 11-58269, the tool holder is made of synthetic resin, so that there is a risk of tool dropping off. So to make this tool-free tool holder, you must use a sturdy material other than synthetic resin.

  Therefore, the inventor attempted to make a tool holder using a metal plate as a material. For this purpose, a metal plate shelf is provided with a notch for accommodating a tool, and an attempt has been made to provide a metal protrusion with a cross-sectional angle as proposed in Japanese Patent Application Laid-Open No. 11-58269 around the notch. However, it takes time and effort to make the metal plate a ridge as proposed in Japanese Patent Application Laid-Open No. 11-58269, and to connect the obtained ridge to a metal plate shelf, welding, etc. This approach has proved unsuitable for practical use because of the complexity of the manufacturing process as a means is required.

Thereafter, the inventor found out that it is suitable to mold with a synthetic resin to make the above-mentioned protrusion. Therefore, the inventor made an attempt to make the protrusions with a synthetic resin and attach the protrusions to a metal plate shelf. In this case, the problem is how to shape the molded body including the protrusions.
The inventor originally thought that it was convenient to make the notch of the shelf that accommodates the tool into a U shape (in other words, a horseshoe shape) with one end opened. Therefore, the inventor considered that the shape of the molded body including the ridges is U-shaped, and that the U-shaped molded body covers the edge of the shelf notch. If the synthetic resin molding covers a part of the metal shelf, the weight of the tool is supported by the metal shelf, so the shelf will drop the tool even if the synthetic resin is deformed. It is because it thought that it did not reach.

  Then, the inner surface of the U-shaped synthetic resin molding is provided with a protrusion having a mountain-shaped cross section. Further, in order to connect the U-shaped synthetic resin molded body to the shelf plate, the outer surface of the U-shaped molded body is formed as a smooth curved surface, and a groove extending in a U shape is formed on the curved surface. In this groove, the notch edge of the shelf board is inserted and connected.

  Thus, the inventor actually made a molded body having the following shape using polypropylene as a synthetic resin. In other words, it is open at one end and is a U-shaped molded body as a whole, and the inner side surface has a mountain-shaped cross section and a ridge extending in a U shape, and the outer side surface is U-shaped. A molded body having a smooth curved surface extending in a shape and having a U-shaped groove formed therein was produced.

  This formed body was attached so as to cover the notch edge of the metal plate shelf, and the tool was actually held in the notch to examine whether the formed body was deformed. As a result, it was confirmed that the formed body was not deformed, and was sufficient to hold the tool as in the conventional metal plate shelf. The present invention has been completed based on such confirmation.

The above-described shelf board can generally be said to be a support board for indicating a tool. Therefore, in this invention, what corresponds to a shelf board is called a support board.
The invention includes an invention of a tool holder and an invention of a method for holding a tool.

  The invention of the tool holder includes a support plate having a U-shaped notch that opens at one end, and a U-shaped synthetic resin molded body that covers the edge of the notch. In addition, the inner surface is provided with a protrusion with a U-shaped cross section extending in a U-shape, and the outer surface is formed into a shape with a groove extending in a U-shape toward the protrusion, Is characterized in that the notch edge of the support plate is inserted into the groove and connected to the support plate.

  The invention of the tool holding method uses a support plate made of a metal plate provided with a U-shaped notch that opens at one end, and a molded body made of a U-shaped synthetic resin that covers the edge of the notch, The molded body is provided with a ridge having a mountain-shaped cross section extending in a U-shape on the inner surface, and is formed into a shape having a groove extending in a U-shape toward the ridge on the outer surface. A notch edge of the support plate is fitted into the groove of the body to form a tool holder, and a tool disc is inserted into the notch of the tool holder to hold the tool.

  In this invention, a support plate made of a metal plate provided with a U-shaped notch that opens at one end, and a U-shaped synthetic resin-made molded body that covers the edge of the notch are used. Are connected to form a tool holder, and the tool holder has a U-shaped notch that opens at one end. Therefore, the tool can be inserted through the opening and easily locked to the tool holder. In addition, since the notch is U-shaped, the tool can be accommodated in the inner part of U, so that there is a slight distance from the accommodation position to the opening, so the tool does not easily fall out of the opening.

Further, in this invention, since the synthetic resin is used to cover the notch edge of the support plate, it is easy to mold the synthetic resin, so that the inner flange surface is provided with a ridge and the outer flange surface is provided with a groove. The covering can be easily made in a single shape. Therefore, it is easy to manufacture the tool holder.
Further, in the present invention, since the protrusions having a mountain-shaped cross section extending in a U-shape are provided on the inner surface of the molded body, the tool holder is inserted into the groove W of the tool disk portion. Therefore, the tool is held in a state where it cannot be moved up, down, left and right, and therefore the tool is securely and securely held. In addition, since the groove W of the tool disk portion is symmetric in the vertical direction, the tool holder can be used in the same manner regardless of whether the tool has the blade portion P facing up or vice versa. The tool can be held.

Furthermore, in this invention, since the groove extending in a U shape is formed on the outer side surface of the molded body, the molded body can be easily connected to the support plate by fitting the notched edge of the support plate into the groove. . Further, since the groove extending in the U-shape is directed to the ridge, the ridge is reinforced by the edge of the support plate, so that a heavy tool can be sufficiently supported.
The tool holder according to the present invention provides the above-described benefits.

On the other hand, the tool holding method according to the present invention inserts the tool disk part into the notch of the tool holder and the tool holder holds the tool, so that the held tool is in the groove W of the disk part. Since the protrusions of the formed body are inserted and held in the tool, the tool is restrained from moving in the vertical direction, the horizontal direction, and further in the front-rear direction. Therefore, the tool is safely and reliably held in the tool holder, and there is no risk of dropping off.
The method of the present invention brings about such an effect.

FIG. 11 is a perspective view of another conventional tool holder.

  FIG. 4 shows a tool holder according to the present invention. This tool holder includes a support plate 1 made by processing a metal plate and a U-shaped molded body 2 made integrally with a synthetic resin. The support plate 1 includes a vertical piece 11 and a horizontal piece 12 connected in an L shape. The vertical piece 11 is provided with a screw hole 111 for fixing to a wall or the like.

  The horizontal piece 12 includes a U-shaped cutout 121, and the cutout 121 opens at the end of the horizontal piece 12. The width F of the notch 121 varies depending on the diameter of the tool disk R. However, since the diameter of the disc portion R is only three types called BT-30, BT-40, and BT-50, it is sufficient to prepare these three types of notches 121.

  The U-shaped molded body 2 is integrally made of a thermoplastic resin such as polypropylene. The overall shape of the molded body 2 is made so as to cover the edge of the notch 121 of the support plate 1. Therefore, the overall shape of the molded body is U-shaped. On the inner surface of the molded body 2, a protrusion 21 is formed that extends in a U shape along the inner surface. The ridges 21 are for fitting into grooves W provided on the outer periphery of the tool disc part. Therefore, the shape of the ridge 21 is made in accordance with the groove W of the tool. The cross-sectional shape of the protrusion 21 is a mountain shape, and is preferably an isosceles trapezoid.

  The outer side of the molded body 2 is a smooth curved surface that originally extends in a U-shape. A groove 22 toward the ridge 21 is formed on the outer side of the outer surface, and the groove 22 extends in a U shape along the outer surface. The groove 22 is for inserting the notched edge 124 of the support plate 1. The cross-sectional shape of the groove 22 is preferably wide at the outer side and narrow at the portion approaching the ridge 21.

  The molded body 2 shown in FIG. 4 can be easily connected to the support body 1 simply by being advanced in the arrow B direction. That is, when the molded body 2 is advanced in the direction of arrow B, the notched edge 124 of the support 1 enters the groove 22 of the molded body 2, so that the molded body 2 is moved until the notched edge 124 is completely fitted into the groove 22. The connection can be established simply by moving in the direction of arrow B.

  FIG. 5 shows a state in which the molded body 2 is connected to the support 1. In the connected state shown in FIG. 5, the cut-out edge 124 of the support 1 reaches the bottom of the groove 22 of the molded body 2, and the cut-out edge 124 enters the base of the protrusion 21 of the molded body. For this reason, the protrusion 21 is reinforced by the cutout edge 124. Therefore, the protrusion 21 has sufficient strength to support the weight of the tool.

  In FIG. 4, drooping pieces 122 are attached to both sides of the horizontal piece 12. The hanging piece 122 is attached to prevent the horizontal piece 12 from being deformed due to the weight of the tool. In FIG. 4, a hole 123 is formed in the horizontal piece 12, but the hole 123 overlaps the hole 23 of the molded body 2 when the molded body 2 is connected to the support plate 1. The molded body 2 can be fixed to the support 1 by pushing the stopper 3 from the overlapped hole 23 into the hole 123.

  The stopper 3 shown in FIG. 4 includes a head 31 that bulges at one end and a locking portion 32 that bulges elastically at the other end. Although the latching | locking part 32 is based on a cylinder, the cylinder is divided | segmented by the dividing line of the axial direction, and the cross section is formed of the several locking piece which exhibits circular arc shape. Therefore, the stopper 3 can squeeze the locking piece and push it into the hole 23. When the stopper 3 is pushed in, the stopper 3 swells in the hole 23 and the hole 123 and can serve as a fixing.

  The tool holder C shown in FIG. 6 is configured in the same manner as the tool holder shown in FIG. That is, the tool holder C is configured by connecting the molded body 2 to the holding plate 1. The holding plate 1 includes a vertical piece 11 and a horizontal piece 12, and a U-shaped notch 121 is formed in the horizontal piece 12. On the other hand, the molded body 2 is provided with a protrusion 21 on the inner side and a groove 22 on the outer side. A notch edge 124 of the support plate is fitted into the groove 22 of the molded product, and the molded product 2 is connected to the support plate 1.

  The tool holder C shown in FIG. 6 is different from the tool holder shown in FIG. 5 in that hook-shaped locking claws 112 are attached to both sides of the upper end of the vertical piece 11. The hook-shaped locking claw 112 is for locking the tool holder C in a locking hole D1 provided in the panel D serving as a standing wall. The tool holder C can be easily locked at an arbitrary position on the panel D by providing a large number of locking holes D1 having the same shape in the panel D. FIG. 6 shows how the tool holder C is used.

  FIG. 6 shows operations necessary to hold the tool A on the tool holder C. That is, the tool A is held on the tool holder C simply by placing the tool A in front of the tool holder C, moving it in the direction of arrow B, and inserting the disc portion R into the notch 121 of the tool holder C. be able to. In this way, holding the tool A on the tool holder C is very simple.

  FIG. 7 shows a state in which the tool holder C holds the tool A as described above. In FIG. 7, since the protrusion 21 of the tool holder C is fitted in the groove W of the tool A, the tool A cannot tilt in the vertical direction, the front-rear direction, or the left-right direction. Therefore, even if the tool holder C vibrates, the tool A does not fall down and therefore does not fall off from the tool holder C.

  FIG. 8 shows a state in which another tool holder C according to the present invention is locked to the panel D and used. The tool holder C in FIG. 8 includes a support plate 1 made of a metal plate and a molded body 2 made of a synthetic resin. The molded body 2 has a protrusion 21 on the inner side surface and a groove 22 on the outer side surface. Since the notch edge of the support plate 1 is inserted into the groove 22 and connected to the support plate 1, the tool holder according to the present invention is provided.

  The tool holder C in FIG. 8 differs from the tool holder in FIG. 6 in that an upward locking claw 113 is attached to the upper end of the vertical piece of the support plate 1. Since the locking claw 113 faces upward, the tool holder cannot be locked to the panel D as it is. Therefore, the fixing plate 4 provided with a new downward locking claw 141 is used to lock the panel D as follows.

  First, the downward locking claw 41 of the fixing plate 4 is inserted into the locking hole D1 of the panel D, the fixing plate 4 is locked to the panel D, and then the vertical piece 11 of the support plate is overlaid thereon, The upward locking claw 113 of the piece 11 is inserted into another locking hole D1, and then the vertical piece 11 is fixed to the fixing plate 4 and integrated, and the tool holder is locked downward with the upward locking claw 113. It fixes to the panel D with the nail | claw 41. FIG. Thus, the tool holder can be firmly fixed to the panel D. In FIG. 8, the vertical piece 11 and the fixing plate 4 are fixed by the stopper 3 shown in FIG.

  Further, FIG. 8 shows that in order for the tool holder C to keep holding the tool reliably, the held tool A slightly moves from the vertical direction to the vertical piece 11, that is, slightly toward the back of the notch. It shows that it is preferable to make it tilted. The angle of inclination is up to 10 degrees. There are various ways to do this. One is to change the thickness of the molded body so that the opening on the upper side of the notch is higher at the side and is inclined within an angle range of 0 to 10 degrees with respect to the horizontal plane. Further, the intersection angle between the vertical piece 11 and the horizontal piece 12 can be changed to an angle range of 80 to 90 degrees, or the extending direction of the vertical piece 11 can be tilted within a range from the vertical direction to an angle of 10 degrees. FIG. 8 shows an example in which the intersection angle between the horizontal piece 12 and the vertical piece 11 intersects at an angle of 80 to 90 on the assumption that the vertical piece 11 extends in the vertical direction.

  FIG. 9 is a front view of the tool holder when the tool is held by the tool holder shown in FIG. 8. In FIG. 9, since the tool A is accommodated in the tool holder C with the ridges 21 of the tool holder C inserted in the grooves W, the tool A can be moved in any direction, up and down, left and right, and front and rear. Cannot move. Therefore, even if the tool holder C vibrates, the tool A does not fall down. Moreover, it does not fall off from the tool holder C.

  The groove W of the tool A originally has an isosceles trapezoidal cross section. If the cross sectional shape of the ridge 21 is the same shape and the same size as the isosceles trapezoid of the groove W as shown in FIG. Even if A is turned upside down, the groove W can be in close contact with the protrusion 21. Therefore, even if the tool faces the blade portion P upward or vice versa, as long as the tool plate portion R is inserted into the notch, the protrusion 21 and the groove W are in close contact with each other. It will be held by the tool holder. This is shown in the drawing. That is, in FIG. 8, the tool holder holds the tool with the blade part P up, and in FIG. 9, the tool with the blade part P down is held.

  Until now, although the case where the tool holder was provided with one notch was demonstrated, the notch is not restricted to one. The tool holder of this invention can be provided with two or more notches arranged side by side on one shelf. FIG. 10 shows an example in which two tool holders are provided on a support plate 1 made of a metal plate shelf.

In FIG. 10, the support plate 1 serving as a shelf plate is composed of a vertical piece 11 and a horizontal piece 12, and the horizontal piece 12 includes two U-shaped notches 121, as described above, at the edge of each notch. A tool holder is made by attaching a molded body 2 made of synthetic resin.
Further, FIG. 10 shows that the tool holder reliably holds the tool when the tool disk portion is inserted into the notch 121 regardless of whether the tool has the blade portion P facing upward or conversely. It is shown that.

  When the molded body 2 is actually made by molding a synthetic resin, if the molded body is in contact with the tool over a wide area, the tool is stably held in the molded body. As shown in FIG. 4, it is preferable to increase the thickness of the portion above the groove 22 and decrease the thickness of the portion below the groove 22. However, if injection molding is performed as it is, a “sink” (dent) is generated in the upper portion, and a good molded product cannot be obtained. In order to prevent this, as shown in the molded body 2 of FIG. 10, if a shallow small groove 6 is formed in a part of the outer peripheral surface of the upper part, a good molded body free from “sink” can be obtained. The molded body 2 shown in FIG. 10 has a groove 6 formed for this reason and is suitable for practical use.

  In general, a tool often has an upper portion and a lower portion that have different heights with the disc portion R as a boundary. Since the tool can be held regardless of whether the tool holder is directed to the lower side or the lower side, the tool can be spatially efficiently held in consideration of the state of the upper space and the lower space of the tool holder. Since the held tool is restrained from being moved by the protrusion provided on the tool holder, it can be safely and reliably held.

  The tool holder according to the present invention comprises a support plate made of a metal plate and a molded body made of a synthetic resin. A groove is formed on the outer side of the molded body, and a notch provided in the support plate in the groove. Since the support plate and the molded body are connected only by inserting the edge, the tool holder can be easily manufactured and the molded body can be easily replaced.

Further, according to the present invention, the tool disk is inserted into the notch of the tool holder and the tool is held by the tool holder, so that the outer diameter of the tool disk is 30, 40 and 50. Since these three types of cutouts are sufficient, the tool can be easily held and is economical.
Since the tool holder and the tool holding method according to the present invention have the advantages as described above, they have high practical value and can be widely used in tool storage devices, tool storage racks, storages, and the like.
