Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a tool holder,
More specifically, the present invention relates to a tool holder that can store a plurality of L-shaped tools in an orderly manner and easily take out a desired one from the plurality of L-shaped tools.

[0002]

2. Description of the Related Art A tool holder capable of accommodating a plurality of L-shaped tools such as an L-shaped spanner is used when carrying a plurality of L-shaped tools of different sizes at one time. ing.

Conventionally, as this type of tool holder, there has been one made of a synthetic resin having a plurality of through holes arranged side by side (first conventional example). In this tool, the longitudinal shaft portion of the L-shaped tool is inserted into the through-hole portion in a one-step or two-step press-fitted state so that the L-shaped tool is elastically held by each through-hole portion. It has become. There were also drawer type tool holders and tool holders with lids (second conventional example). In any of the tool holders of the first conventional example and the second conventional example, in the stored state, the lateral shaft portions of the L-shaped tools are arranged so as to overlap each other.

[0004]

However, in the first conventional example, since the longitudinal shaft portion of the L-shaped tool is inserted into the through hole portion in a press-fitted state, there is resistance when the L-shaped tool is taken in and out,
In addition, since the L-shaped tool cannot be held unless the elastic resistance is large, a larger (thick) L-shaped tool requires a larger elastic resistance and tends to be difficult to move in and out. Further, since the lateral shaft portions of the L-shaped tools are arranged and stored so as to be overlapped with each other, a desired one of the plurality of L-shaped tools stored is accommodated in the through-hole portion that holds the desired one. When pulling it out of the L-shaped tool, it is necessary to rotate the other L-shaped tools stored outside the L-shaped tool to be taken in and out to allow those sideways shafts to escape to a position that does not interfere, which makes it inconvenient to put in and take out. There was a problem with.

Also in the second conventional example, similarly, since the lateral shaft portions of the L-shaped tools are arranged and stored so as to be overlapped, the L-shaped tools other than the L-shaped tool to be put in and taken out are stored.
There is a problem in that it is necessary to rotate or move the shaped tool to a position where it does not interfere, or to rotate the L-shaped tool to be put in and taken out, which is inconvenient to put in and take out.

The present invention has been made in view of the above circumstances and problems, and it is easy to take in and out a plurality of L-shaped tools, and a holder for a tool that can store a plurality of L-shaped tools in an orderly manner. The purpose is to provide.

It is another object of the present invention to provide a tool holder which requires a small number of parts and can be constructed compactly.

[0008]

A tool holder according to the present invention is provided with a horizontal shaft extending through a curved neck at the upper end of a vertically long shaft between a plurality of partition walls provided side by side on a base member. A shaft insertion portion into which the vertically long shaft portion of the L-shaped tool is rotatably fitted is partitioned and formed, and a cover member that covers each shaft insertion portion is formed in the base member at an upper closed position. Is vertically slidable between the upper and lower open positions, and the upper end surfaces of the plurality of partition walls are L-shaped.
The curved neck portion of the L-shaped tool is formed as a tip-down inclined surface for swiveling around the longitudinal shaft portion while sliding the curved neck portion of the L-shaped tool downward, and the upper end portion of the cover member is the curved neck portion or the lateral shaft portion of the L-shaped tool. It is formed as a support part that supports the.

In this tool holder, the shaft insertion portion must be formed by a groove-shaped space that is slightly larger than the diameter of the longitudinal shaft portion of the L-shaped tool. The longitudinal shaft of the shaping tool can be rotatably loosely fitted. The tip-down inclined surface formed by the upper end surfaces of the plurality of partition walls can be formed by obliquely cutting the upper ends of the respective partition walls.

As described above, when the upper end portion of the partition wall forming the shaft insertion portion is formed as a downwardly inclined surface, the cover member slides from the upper closed position to the lower open position. As a result, the bent neck portion or the lateral shaft portion of the L-shaped tool, in which the vertically long shaft portion is inserted into the shaft insertion portion,
While being supported by the supporting portion of the cover member, the L-shaped tool slides downward on the downwardly inclined surface of the partition wall by turning downward, and turns around the vertically long axis portion to change the direction so as to protrude from the base member. This action is performed for all L-shaped tools in which the longitudinal shaft portions are loosely fitted in the individual shaft insertion portions by simply sliding the cover member downward from the closed position to the open position. In the open position, the lateral shafts of all L-shaped tools project to the front of the base member, and in that state, the lateral shafts of the individual L-shaped tools are located in the vertical overlapping position. Since it is no longer present, the desired L-shaped tool can be pulled out and taken out from the shaft insertion portion without any resistance without being disturbed by other L-shaped tools.

When the bent neck portion or the lateral shaft portion of the L-shaped tool slides down on the downwardly inclined surface and slides down, the width of the shaft insertion portion required for turning the laterally oriented shaft portion is as large as that of the downwardly inclined surface. Although it varies depending on the tilt angle, the size of the L-shaped tool, the bending angle of the bent neck, etc., generally, the diameter (thickness) of the longitudinal shaft of the L-shaped tool loosely fitted in the shaft insertion part It is desirable to make the size 10% to 50% larger than that of), and the ratio tends to increase as the diameter of the longitudinal axis portion decreases. Further, the desirable inclination angle of the front-down inclined surface for turning the lateral shaft portion by the weight of the L-shaped tool is 25 to 35 degrees with respect to the surface of the base member.

According to the present invention, the plurality of the partition walls have the descending slopes arranged stepwise in the width direction of the base member, and the supporting portions of the cover member slope in the aligning direction of the descending slopes. It is desirable that they extend. According to this, when the bent neck portion or the lateral shaft portions of the plurality of L-shaped tools are mounted on the support portion of the cover member in the open position, when the cover member is slid upward to the closed position, each L-shaped tool is formed. The bent neck portion or the lateral shaft portion of the tool is pushed up by the support portion of the cover member to move upward while sliding on the downwardly inclined surface, and is collapsed toward the base member side so that a plurality of L-shaped tools are lined up in order.

By the way, according to the present invention, when the cover member is slid from the open position to the closed position, the lateral shaft portion of the L-shaped tool swivels toward the base member side while moving upward on the downwardly inclined surface. The swirling action plays an important role in its function. It can be said that the larger the distance between the longitudinal shaft portion of the L-shaped tool and the support portion of the cover member, the better the smooth swiveling action of the L-shaped tool. This is because the gap between the longitudinal shaft portion of the L-shaped tool and the support portion of the cover member is too narrow, for example, if the width of the insertion portion is too narrow with respect to the thickness of the longitudinal shaft portion of the L-shaped tool, the L-shaped tool. The bent neck portion is supported by the support portion of the cover member at a position near the upper end of the vertically long shaft portion, and it becomes difficult for the L-shaped tool to smoothly rotate. However, conversely, if the width of the insertion portion is too wide with respect to the thickness of the longitudinal axis portion of the L-shaped tool, the rattling of the L-shaped tool increases in a state where the L-shaped tool is housed, which is a practical problem. Lacks sex.

Therefore, in the present invention, the cover member includes
A protrusion is provided corresponding to the shaft insertion portion so as to abut the lengthwise shaft portion of the L-shaped tool loosely fitted in the shaft portion insertion portion and maintain the distance between the lengthwise shaft portion and the support portion of the cover member. , Is adopted.

By doing so, since the swiveling action of the L-shaped tool is performed smoothly, the width of the insertion portion is widened with respect to the thickness of the longitudinal axis portion of the L-shaped tool, resulting in unacceptable rattling. Even in this case, rattling due to the above-mentioned protrusions can be suppressed to an allowable range with practicality, and a sufficient distance can be maintained between the longitudinal shaft portion of the L-shaped tool and the support portion of the cover member. , By sliding the cover member upward from the open position to the closed position, the lateral shafts of all L-shaped tools will surely fall to the base member side.
All L-shaped tools line up neatly.

In the present invention, the projections are provided corresponding to at least two or more of the shaft insertion portions, and these projections have a sufficient space between the longitudinal shaft portion of the L-shaped tool and the support portion of the cover member. In order to keep the above, it is desirable that they are lined up along the supporting portion.

According to the present invention, the longitudinally elongated shaft portion of the L-shaped tool is formed in a polygonal shape or a circular shape in cross section, and the protrusion is provided in the shaft insertion portion when the cover member is in the open position. It is possible to adopt a configuration in which a rib is formed which abuts the longitudinal axis of the L-shaped tool that is fitted, and the top of the rib is located parallel to the plane of the base member. According to this, when the lateral shaft portion of the L-shaped tool is pushed and swung by the tip-down inclined surface of the partition wall or the support portion of the cover member, the tops of the ribs forming the protrusions of the L-shaped tool are Friction is reduced by pushing the vertically long shaft to keep the distance between the vertically long shaft of the L-shaped tool and the support of the cover member sufficiently wide and reducing the contact area between the vertically long shaft of the L-shaped tool and the cover member. , The turning action of the L-shaped tool can be smoothly performed.

According to the present invention, the L-shaped tool, which is pushed up by the supporting portion of the cover member and is tilted toward the base member, is disposed above the lateral shaft of the L-shaped tool so that the L-shaped tool can be removed from the shaft insertion portion. It is preferable that the retaining projection is provided on the base member to prevent the L-shaped tool from falling off when the cover member is closed.

Further, according to the present invention, the cover member is provided with the protrusion and an auxiliary protrusion which is a position lower than the protrusion and which abuts a vertically long shaft portion of the L-shaped tool loosely fitted in the shaft insertion portion. Is desirable. According to this, the effect of maintaining the distance between the longitudinal axis portion of the L-shaped tool and the support portion is more significantly exerted by the auxiliary protrusion.

It keeps the distance H from.

The operation of the tool holder configured as described above will be described.

As shown in FIG. 1, the longitudinally long shaft portions 51 of the plurality of L-shaped tools 5 are connected to the plurality of shaft insertion portions 13 on the base member 1 side.
(See FIG. 2) When the cover member 2 is slid upward to the closed position while loosely fitted,
Since the support portion 21 of the cover member 2 faces the lateral shaft portion 53 of the L-shaped tool 5 that is tilted toward the base member 1, the lateral shaft portion 53 pivots in a direction in which the lateral shaft portion 53 projects from the base member 1 and a plurality of lateral shaft portions 53 are rotated. The alignment of the L-shaped tools 5 ... Is not disturbed. At this time, the plurality of retaining projections 15 are separately positioned above the lateral shaft portions 53 of each L-shaped tool 5 to prevent the L-shaped tool 5 from being detached. The situation of falling out from the shaft insertion portion 13 does not occur.

When the cover member 2 is slid downward from the closed position of FIG. 1 to the open position of FIG. 2, the bent neck portion 52 of the L-shaped tool 5 is supported by the support portion 21 of the cover member 2 while The L-shaped tool 5 is rotated about the vertically long shaft portion 51 while sliding downward on the downwardly inclined surface 14 of the partition wall 12 by its own weight, and as a result, as shown in FIG.
Turn so that 3 projects from the base member 1. In this state, the lateral shaft portion 53 of each L-shaped tool 5 is shown in FIG.
Since it is not located at the overlapping position in the vertical direction as shown in FIG. 5, it is possible to pull out the desired L-shaped tool 5 upward from the shaft insertion portion 13 without being disturbed by other L-shaped tools 5. . Further, at this time, as shown in FIG. 8, the protrusions 22 and the auxiliary protrusions 26, 27 on the cover member 2 side hit the longitudinal shaft portions 51 of the respective L-shaped tools 5 ... And the longitudinal shaft portions 51 of the L-shaped tool 5 and the cover member. The distance H from the second supporting portion 21 is maintained.

Next, from the state where the bent neck portion 52 of the L-shaped tool 5 is mounted on the support portion 21 of the cover member 2 in the open position as shown in FIG. 2, the cover member 2 is slid upward to the closed position. And the bent neck portion 52 of the L-shaped tool 5 covers the cover member 2
Is pushed up by the support portion 21 of the
While sliding and moving upward, it falls toward the base member 1 side. Therefore, when the cover member 2 is located at the closed position as shown in FIG.

Is secured for a long time. Therefore, when the cover member 2 is slid upward from the open position, the lateral shaft portion 53 is smoothly collapsed toward the base member 1 side by the principle of leverage. In other words, by sliding the cover member 2 from the open position to the closed position, a large rotational moment is applied to the bent neck portion 52, so that the lateral shaft portion 53 can be smoothly tilted toward the base member 1 side. . Therefore, in order to smoothly perform the turning action of the L-shaped tool 5, the larger the distance H between the vertically long shaft portion 51 of the L-shaped tool 5 and the support portion 21 of the cover member 2, the better. The narrower the distance H between the longitudinal shaft portion 51 and the supporting portion 21 of the cover member 2, the more the curved neck portion 52 is supported by the supporting portion 21 of the cover member 2 at a position closer to the upper end of the longitudinal shaft portion 51 of the L-shaped tool 5. Therefore, it becomes difficult for the turning action of the L-shaped tool 5 to be performed smoothly.

Further, when the cover member 2 is located at the open position as shown in FIG. 2, the protrusions 22 on the cover member 2 side and the top portions 23 of the auxiliary protrusions 26 and 27 have the vertically long shaft portion 5 of the L-shaped tool 5.

Even if the longitudinal axis portion 51 is formed in a polygonal cross-section (hexagonal shape in the example) as in the L-shaped tool 5 shown in FIG. The contact area between the portion 51 and the cover member 2 is reduced (the protrusions 22 and the top portions 23 of the auxiliary protrusions 26 and 27 have the base member 1 as shown in FIG.
4 and 5, the projections 22 and the auxiliary projections 26 and 27 are formed in the shape of a triangular pyramid, and their contact with the top portion 23 is a point as shown in FIG. Therefore, the friction is reduced, and the distance H between the vertically long shaft portion 51 of the L-shaped tool 5 and the support portion 21 of the cover member 2 is maintained at L.
The turning action of the shaping tool 5 can be smoothly performed.

In this embodiment, when the cover member 2 is slid vertically between the closed position and the open position,
The bent neck portion 52 of the L-shaped tool 5 is the support portion 21 of the cover member 2.
However, the lateral shaft portion 53 of the L-shaped tool 5 may be supported by the support portion 21 of the cover member 2 in this respect.

In addition, in this embodiment, auxiliary protrusions 26 and 27 are provided in addition to the protrusion 22. However, this point is that only the protrusion 22 allows the support member 2 side of the L-shaped tool 5 and the support portion of the cover member 2. One or both of the auxiliary protrusions 26 and 27 may be omitted as long as the distance H from the gap 21 is maintained.

Further, in this embodiment, the base member 1
Although the projection 22 and the auxiliary projections 26 and 27 are made to face the fifth to fifth shaft insertion portions 13 ... Of the six shaft insertion portions 13 ... A protrusion or an auxiliary protrusion facing the portions 13 ... May be provided.
In this embodiment, the sixth axial insertion portion 13 is not provided with a projection or an auxiliary projection that faces the sixth axial insertion portion 13 because the size of the L-shaped tool 5 loosely fitted is large. This is because if the projections or the auxiliary projections facing the shaft insertion portion 13 are provided, the overall thickness of the tool holder becomes thicker, so that it is avoided.

In this embodiment, the shaft inserting portion and the cover member having the same structure are provided on both the left and right sides of the base member 1, but this point is only on one side of the base member 1. May be provided.
