DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger for hanging a tool having a rod-shaped portion such as a screwdriver or a drill for display and sale in a hanging state.

[0002]

2. Description of the Related Art There are conventionally known hanging hangers of this type, as shown in FIGS. The hanger 21 is for display and sale of the driver 20, is formed in a rectangular frame shape from a flexible synthetic resin, has a hanging hole 22 for suspension at an upper portion, and forcibly presses the driver shaft D from below. A pair of front and back holding portions 23 that hold the coaxial portion D in a suspended state by being inserted therethrough are provided at the lower portion.

The pair of holding portions 23 are formed in a horizontally long flat plate shape, and are integrally provided at a lower portion of the hanger 21 so as to approach each other in the front and back directions. An elongated hole 24 penetrating in the up-down direction and extending in the left-right direction is provided between opposing inner surfaces of the pair of holding portions 23. Accordingly, by inserting the shaft portion D into the center of the elongated hole 24, the pair of holding portions 23 are elastically deformed outward in the front and back directions, and the elongated hole 24 is expanded. As shown, the restoring force F of the holding portion 23 holds and holds the driver shaft portion D.

[0004]

In the above prior art,
Since the pair of holding portions 23 are formed in a flat plate shape, and opposing inner surfaces for holding the driver shaft portion D are formed in a simple flat shape, as shown in FIGS. 12 and 13, The restoring force F of the clamping portion 23 acts only along the center line L in the front-back direction, and the left-right deflection of the shaft portion D is restricted by the frictional force between the coaxial portion D and the clamping portion 23. Not just. For this reason, in the suspended state of the driver, the shaft portion D is likely to sway relatively to the hanger 21 (shake in the direction of the arrow a in FIG. 11), and the shaft portion D is suddenly moved from the holding portion 23 due to the side sway. Sometimes it came off.

On the other hand, as means for solving such inconvenience, it is conceivable to change the holding portion 23 to a harder or thicker synthetic resin material which is more difficult to deform. However, such a means makes it difficult to insert and remove the driver shaft D between the holding portions 23, and forcibly applies the shaft D
Is inserted between the holding portions 23, the holding portion 23 is plastically deformed and easily broken. Further, when the holding portion 23 is formed in a flat plate shape, in order to expand and contract the long hole 24 so as to insert and remove the shaft portion D between the holding portions 23, bending is mainly generated in the center portion of the holding portion 23 in the left-right direction. concentrate. For this reason, in the conventional hanger 21, while the insertion and removal of the shaft portion D are repeated, the holding portion 23 is easily broken from the central portion thereof, which also has a problem in durability.

In view of such circumstances, the present invention effectively suppresses the lateral deflection of the rod-shaped portion with respect to the holding portion without making the insertion and withdrawal work of the rod-shaped portion difficult, and the rod-shaped portion is unexpectedly moved from the holding portion. The purpose is to prevent falling off. Another object of the present invention is to improve the durability against repeated insertion and removal of the rod-shaped part by dispersing the bending of the holding part when the rod-shaped part is inserted in the left-right direction.

[0007]

In order to achieve the above object, the present invention takes the following technical measures. That is, according to the present invention, the hook portion 2 is formed on the upper portion, and a pair of elastically deformable front and back clamping portions 3, 3 are formed on the lower portion. In a hanging hanger in which the bar-shaped portion D of the tool is held in a suspended state by forcibly inserting the portion D, only a vertically extending portion is provided between the pair of holding portions 3.

A pair of left and right first abutments from both left and right sides of the
Two contact portions 7 and 8 are provided, and both left and right of the first contact portion 6 are provided.
On the side, inner cuts 9 and 10 communicating with the long hole 5 are formed.
On the left and right sides of the first contact portion 6 at the center in the left-right direction.
Following the cuts 9, 10, the second contact parts 7, 8 are symmetrical
And the outer surface side of the first contact portion 6 is oriented in a front-to-back direction.
Outer cut 1 cut in V shape from outside to inside
1 is provided .

In the present invention, the hook portion 2 is formed at the upper portion, and a pair of elastically deformable front and back clamping portions 3, 3 are formed at the lower portion, and the pair of clamping portions 3, 3 are formed at the lower portion.
In a hanging hanger in which the bar D of the tool is held in a suspended state by forcibly inserting the bar D of the tool between the pair of holding portions 3, 3,
A long hole 5 penetrating in the vertical direction and extending in the horizontal direction is formed.
The pair of holding parts 3 and 3 forcibly hold the bar D of the tool.
When it is inserted, it bends in the front and back directions and the long hole 5 becomes freely expandable and contractable.
With a high degree of flexibility, on the inner surface of each
Are left and right abutments from both left and right sides of the bar D of the tool.
A pair of abutting portions 7 and 8 are provided to abut the bar D of the tool.
A pair of right and left abutments so that the four points are supported by the parts 7 and 8
Between the parts 7 and 8, the outside in the front and back direction communicates with the long hole 5.
A wide, generally fan-shaped central cut 13 is provided.
The contact portions 7 and 8 are provided on both left and right sides of the center cut 13.
They are arranged symmetrically .

In the present invention, the hook portion 2 is formed at the upper portion, and a pair of front and back holding portions 3, 3 which are elastically deformable and are close to each other are formed at the lower portion.
In a hanging hanger in which the bar D of the tool is held in a suspended state by forcibly inserting the bar D of the tool between the pair of holding portions 3, 3,
A long hole 5) penetrating in the vertical direction and extending in the horizontal direction is formed.
Then, the pair of holding portions 3 and 3 forcibly press the bar D of the tool.
When inserted into the slot, it bends in the front and back direction to allow the elongated hole 5 to expand and contract.
With a certain degree of flexibility, a long hole is provided on both sides of the long hole 5 in the front and back directions.

Is what it is.

In this case, since the plurality of abutting portions independently abut on portions of the outer peripheral surface of the rod-shaped portion which are away from the center line facing the front and back directions, the restoring force of the holding portion is dispersed in directions other than the center line. Is done. Therefore, the rod-shaped portion inserted between the holding portions receives forces from a plurality of directions (FIGS. 5 and 8).
And FIG. 10), and the lateral deflection of the rod-shaped portion with respect to the holding portion can be effectively suppressed. In the present invention described above, in order to more effectively suppress the lateral deflection of the rod-shaped portion with respect to the holding portion, it is preferable that the pressing force from each contact portion is uniformly applied to the periphery of the rod-shaped portion toward the center thereof.

For this reason, the present invention recommends that the plurality of abutting portions be arranged symmetrically with respect to a center line facing the front and back directions of the holding portion. In the case where the plurality of contact portions are formed directly on the holding portion itself, the contact portions may be formed by edges of cuts formed on opposed inner surfaces of the pair of holding portions. Furthermore, the present invention recommends that the pair of holding portions be formed in a plane cross section having a symmetrical waveform with respect to a center line facing the front and back directions. In this case, since the holding portion is formed in a corrugated plane cross section, when the bar-shaped portion is forcibly inserted and the holding portion is deformed, the bending is distributed to various portions of the holding portion in the left-right direction (see FIGS. 5 and 5). 8), and the bending is prevented from being concentrated on the central portion in the same direction.

In the case where the plurality of abutting portions are formed not between the pair of holding portions themselves but between them, the free ends of the holding arms provided between the opposing inner surfaces of the pair of holding portions. It can also be configured.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of the present invention. The hanging hanger 1 according to this embodiment is made of an elastic material such as a synthetic resin having flexibility, and has a substantially rectangular frame shape when viewed from the front. That is, this hanger 1 has a hook portion 2 formed in a horizontally long slot shape at an upper portion, and a pair of front and back surfaces for inserting and holding a driver shaft portion D which is a bar portion of an article in a vertical direction in a suspended state. And the holding portions 3 and 3 are integrally provided.

The hanger 1 is formed symmetrically in the front and back and in the left-right direction.
A plurality of shallow recesses 4 are provided. In addition, hanger 1
The inside of the rectangular frame is formed large enough to receive the tip of the driver shaft D without obstacles. As shown in FIGS. 1B and 2, the pair of holding portions 3 are arranged close to each other so that the width in the front-back direction (the vertical direction in FIG. 2) is thicker than other portions. An elongated hole 5 penetrating in the up-down direction and extending in the left-right direction is formed between the holding portions 3.

The pair of holding portions 3, 3 have such a flexibility that when the shaft portion D is forcibly inserted, it bends in the front and back directions so that the elongated hole 5 can be expanded and contracted. The left and right ends 5 of the elongated hole 5
A and 5B are arc-shaped surfaces to prevent concentration of stress when the holding portion 3 is deformed outside. Also, on the opposing inner surface sides of each of the holding portions 3, a first contact portion 6 that contacts the center portion in the left-right direction of the driver shaft portion D and a pair of left and right second contact portions that contact the left and right sides of the coaxial portion D. Two contact portions 7 and 8 are provided.

Of these contact portions 6, 7, 8, the first contact portion 6 is for holding a relatively small-diameter driver shaft portion D, which will be described later, and is substantially the same as the small-diameter shaft portion D. It has an arc-shaped contact surface curved at the same curvature. On the other hand, the pair of left and right second contact portions 7 and 8 are for holding a relatively large-diameter driver shaft portion D, which will be described later, and are formed by the shaft portion D portion inserted between the holding portions 3 and 3. The outer peripheral surface is provided symmetrically left and right away from the first contact portion 6 so as to independently contact a portion away from the center line L1 facing the front and back directions.

That is, on the left and right sides of the first contact portion 6,
Inner cut 9,10 running deep in the radial direction and up and down
Are formed, and the second contact portions 7 and 8 are formed by edges of the cuts 9 and 10, respectively. In other words, on the left and right sides of the first contact portion 6 at the center in the left-right direction,
Subsequent to the inner cuts 9, 10, the second contact portions 7, 8 are arranged symmetrically. In the present embodiment, the driver shaft portion D having the minimum diameter held by only the first contact portion 6 is used.
Is set to about 1.25 mm, and the arc-shaped surface of the first contact portion 6 is set to the same diameter as the minimum shaft portion D.

The outer surface of the central portion of each of the holding portions 3, 3 is formed so as to bulge in an arc shape in a plan view, and an outer cut 10 is formed in the bulging portion. The outer cut 10 is formed by moving the outer surface of the first contact portion 6 between the inner cuts 9, 10 from the outside toward the center C of the elongated hole 5.
It is formed in a shape cut into a shape. As described above, the left and right holding portions 3, 3 are formed with cuts 1, 10, 11 alternately in the bulging portion, so that a plane cross section having a symmetrical waveform with respect to the center line L1 facing the front and back directions. Is formed.

The lower part of the first contact portion 6 is shown in FIG.
(B) and as shown in FIG. 3, the spherical insertion guide surface 12
Are formed, so that the driver shaft portion D can be easily and smoothly inserted between the holding portions 3. In the present embodiment according to the above configuration, first, when a relatively small diameter driver shaft portion D is inserted between each of the holding portions 3, 3, as shown in FIG. It is held by the first contact portions 6 and 6. At this time, the circular arc surfaces of the first contact portions 6 and 6 are stably held on the driver shaft portion D in close contact.

When the shaft portion D slightly larger than the diameter of the arcuate surface of the first contact portions 6 and 6 is inserted, the notch 11 is widened in addition to the elasticity of the material of the hanger 1 so that the driver shaft portion is expanded. The circular arc surfaces of the first contact portions 6 and 6 are deformed and adhere to D. On the other hand, when the diameter of the driver shaft portion D is relatively large, the left and right second contact portions 7, 8 in addition to the first contact portion 6 contact the coaxial portion D, as shown in FIG. The shaft portion D is held between the holding portions 3 and 3 by these contact.
In this case, the pair of holding portions 3, 3 extended to the front and back outer sides are elastically deformed such that the central outer cut 11 expands and the left and right inner cuts 9, 10 are narrowed, and the bending in each portion in the left-right direction is dispersed. In this state, when the shaft portion D is inserted, the deformation is prevented from being locally concentrated, thereby improving the durability in repeated use.

Further, since the first and second contact portions 6, 7 and 8 independently contact the outer peripheral surface of the shaft portion D, the pair of holding portions 3, 3 elastically deformed as described above. Are the inward radial component forces f1 to f toward the center of the shaft portion D.
3 and acts on the shaft portion D. For this reason, the mounted shaft portion D is effectively prevented from laterally touching the holding portions 3, 3, and is held in a stable state between the holding portions 3, 3. That is, according to the present embodiment, the force for holding the large-diameter driver shaft portion D is dispersed in six directions, and the shaft portion D is stably held by each of the contact portions 6, 7, and 8, so that the coaxial The swinging of the portion D relative to the hanger 1 in the left-right direction is prevented as much as possible.

Further, since the holding force is distributed to the contact portions 6, 7, and 8, the insertion and removal of the rod portion (driver shaft portion D) of the tool can be easily performed with a relatively small force. There is less risk of breakage because it is easy. 6 to 8
Shows a main part of the second embodiment of the present invention. This embodiment is different from the first embodiment in that the central first contact portion 6 and the outer cut 11 are eliminated, and a substantially fan-shaped central cut 13 is provided between the pair of left and right second contact portions 7 and 8. It is in the point.

For this reason, in the present embodiment, both the case of the relatively small-diameter shaft D shown in FIG. 7 and the case of the relatively large-diameter shaft D shown in FIG. , 8 for four points. Since other configurations and operations are almost the same as those of the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals as those in FIG. 9 and 10 show a main part of a third embodiment of the present invention.

This embodiment is different from the first and second embodiments in that the contact portion is not formed on the holding portions 3 and 3 itself, but is a separate member interposed between the holding portions 3 and 3. The point is that it is constituted by the arms 16 and 17.
That is, in the present embodiment, the second long holes 14 and 15 substantially parallel to the long holes 5 are provided between the holding portions 3 and 3,
By making the second elongated holes 14 and 15 communicate with the elongated hole 5 at the center, a total of four holding arms 16 and 17 are formed symmetrically on the front and back and right and left.

By forming the distal end surfaces of the holding arms 16, 17 in an arc shape, the arms 16, 1
Each of the second contact portions 7 and 8 is formed at the free end of 7. Therefore, in this case, the driver shaft portion D inserted between the holding portions 3, 3 is held in a state where not only the restoring force of the holding portions 3, 3 but also the restoring force due to the bending of the holding arms 16, 17 is added. Will be. Also in the third embodiment,
The force for holding the driver shaft portion D is sandwiched from four directions by the four second contact portions 7, 8 provided symmetrically to the left and right with an equal holding force. When the driver shaft D has a small diameter (indicated by a chain line in FIG. 9),
In both cases of the large diameter shown in FIG. 10, it is sandwiched from four directions and is stably held, so that relative swing in the left and right directions is prevented.

In the third embodiment, when the driver shaft D has a large diameter, as shown in FIG.
The outer portions of the long holes 14 and 15 also bend and the holding force is increased, and the holding of the driver shaft portion D is reliably and firmly performed. The present invention is not limited to the above embodiment. For example,
The shapes of the cuts 9, 10, 11, 13 of the holding portions 3, 3 are not limited to those in the illustrated example, and can be changed as appropriate. In addition to the driver shaft D, the hanger 1 includes drills and other tools and stationery (for example, hanging exhibits such as pens and pen holders).
It can be used not only for hanging round bars such as, but also for hanging various articles having other bar-shaped portions.

[0027]

As described above, according to the present invention,
Since the restoring force of the pinching portion is dispersed in a direction other than the center line facing the front and back directions to pinch the rod portion, the insertion and removal of the rod portion is not made difficult, and the rod portion is moved laterally with respect to the pinching portion. The run-out can be effectively suppressed, and the rod-shaped portion can be prevented from unexpectedly dropping from the holding portion. Further, according to the present invention, since the bending of the holding portion when the rod portion is inserted is dispersed in the left-right direction, the durability against repeated insertion and removal of the rod portion can be improved.
