[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape of a hanger hook.

[0002]

2. Description of the Related Art A hanger hook 2 conventionally used widely.
As shown in FIGS. 9 and 10, is fixed to the upper center of the main body 1 having the arm portion 5 and is used to suspend the main body 1.

[0003] The hanger hook 2 has a slender columnar shape made of metal and has a hanging portion 2 a formed into a circular shape and a straight portion 2 b inserted into the main body 1. A head 3 is provided at the tip of the hanging portion 2a. In addition, the linear portion 2
b has several steps of corrugated grooves 2c from the middle and continues to a tapered tapered step 2d. The tapered step 2d
Is provided with a spherical ball 2e.

The straight portion 2b of the hanger hook 2 is inserted into and engaged with a vertical hole 4 in the center of the arm portion 5 at the upper part of the body 1 of the hanger. The vertical hole 4 includes a large hole 4a extending from the entrance portion to the lower side of the main body 1, and a small hole 4b located below the large hole a. The large hole 4a is larger than the diameter of the hanger hook 2, and the small hole 4b is
It is formed smaller than the diameter of the thick hole 4a.

A hanger is made by connecting the hanger hook 2 and the main body 1 as described above. The connection between the hanger hook 2 and the main body 1 is such that the linear portion 2b of the hanger hook 2 is inserted into the vertical hole 4 of the main body 1 from its tip before the main body 1 is cooled and solidified. The insertion of the hanger hook 2 ends when the ball 2e at the tip of the linear portion 2b reaches the tip of the pore 4b. Then, the groove 2c is accommodated in the pore 4b. In addition, hanger hook 2
The pores 4b in which the groove portions 2c are set are artificially compressed from the outside of the main body 1 by a compressor such as a cylinder, and are processed so that the hanger hook 2 does not fall out of the vertical holes 4 in the upward direction.

As described above, the hanger hook 2 is fixed to the main body 1 so that the hanger hook 2 does not come off from the main body 1 even if it is hung by a hanging bracket or the like.

[0007]

In the conventional hanger hook, when the hanger hook 2 is inserted into the vertical hole 4 of the main body 1, the straight portion 2b, the groove 2c, the tapered step 2d, and the ball 2e are formed. Since it has the same diameter and is smaller than the diameter of the thick hole 4a, there is an advantage that it can be easily inserted into the vertical hole 4.
However, since the diameters are the same, the hanger hook 2 is inserted into the vertical hole 4, and the groove 4c into which the groove 2c is inserted so that the hanger hook 2 does not come off.
b must be compressed from the outside of the body 1 and the pores 4b
Required a compressor for compressing the oil from the outside.

[0008] As described above, in order to secure a sufficient bonding strength, a molding step of compressing with a compressor is indispensable. As a result, there is a problem that the manufacturing process becomes longer and the manufacturing cost increases.

An object of the present invention is to provide a hanger hook that can be easily and reliably attached to a main body.

[0010]

Means for Solving the Problems In order to solve the above problems, in the hanger hook of the present invention, before the body of the hanger is cooled and solidified, the hanger hook inserted and attached to the body has a tip. A first insertion portion having a tapered portion, a cylindrical second insertion portion continuing from the first insertion portion, and a second insertion portion continuing from the second insertion portion;
And a third insertion portion provided with a step portion having a larger diameter than the insertion portion.

Further, the third insertion portion has an inverted truncated cone shape,
An upper bottom portion having a diameter larger than the diameter of the hanger hook, a lower bottom portion having a diameter smaller than the diameter of the hanger hook, and a load are provided.

Further, a plurality of the third insertion portions are provided.

[0013]

In the above construction, when the hanger hook is inserted before the main body is cooled and solidified, the first insertion portion having a tapered tip portion is provided, so that the hanger hook is inserted into the main body. Easier to do.

Further, since the second insertion portion having a cylindrical shape following the first insertion portion is provided, the hanger hook inserted by the first insertion portion is guided to be inserted vertically.

Further, since the third insertion portion provided with the step portion continuously protruding from the second insertion portion is provided, the main body of the hanger is pushed out by the third insertion portion. As a result, the pressure on the inner portion of the main body pushed by the hanger hook is increased. Then, when the hanger hook is further pushed in and the third insertion portion passes, the inner portion of the main body enters above the third insertion portion to return to the original shape due to the increased pressure. Thereafter, when the main body is completely cooled and solidified, a part of the main body enters above the third insertion portion, and the hanger hook does not come off in a form engaged with the main body and the third insertion portion.

Further, by forming the third insertion portion into an inverted truncated conical shape, when the third insertion portion is inserted into the main body, the main body is gradually pushed and spread along the side surface of the third insertion portion, and Pressure increases. At this time, since the third insertion portion has a side surface that is oblique to the direction in which the hanger hook is inserted, the hanger hook is smoothly inserted into the main body.

On the other hand, the upper bottom portion of the third insertion portion is thicker than the diameter of the hanger hook, and a step is formed between the hanger hook and the third insertion portion. For this reason, when the third insertion portion advances to the back of the main body, the volume above the upper bottom becomes small, and the pressure inside the main body becomes low. As described above, the pressure on the lower side of the third insertion portion is high, and the pressure on the upper side is low, and the pressure inside the main body becomes uneven. To solve this, the lower part of the third insertion portion flows upward inside the main body,
A phenomenon occurs in which the internal pressure is equalized. Thereby, a part of the main body enters the upper side of the third insertion portion. When the main body is completely cooled and solidified, a part of the main body becomes the third
The hanger hook does not come off in the form of being engaged with the main body and the third insertion portion because it is inserted into the upper side of the insertion portion.
Furthermore, since the upper bottom of the third insertion portion has a diameter larger than the diameter of the hanger hook and is a surface that protrudes vertically from the center axis of the hanger hook, when the hanger hook tries to slip upward, The pressing force is applied in the vertical direction, and the pressing force works to the maximum without dispersing. Therefore, the engagement between the hanger hook and the main body becomes stronger.

Furthermore, by providing a plurality of the third insertion portions, each has an independent upper bottom portion and a lower bottom portion,
Since the respective third insertion portions are engaged with the main body in a manner similar to the above-described principle, the engaging force between the hanger hook and the main body becomes stronger.

As described above, there is no need to perform a compression operation by a compressor to fix the hanger hook, and the manufacturing process is simplified.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In the hanger hook 2 as shown in FIG.
It is fixed to the upper center of the main body 1 having the arm 5 and is used to suspend the main body 1.

As shown in FIGS. 1 and 2, the hanger hook 2 has a slender columnar shape made of metal and has a hanging portion 2a formed into a circular shape and a straight portion 2b inserted into the main body 1. A head 3 is provided at the tip of the hanging portion 2a. The diameter of the hanger hook is E.

As shown in FIGS. 3 and 4, the linear portion 2b is provided with several inverted truncated conical third insertion portions 2h from the middle. The third insertion portion 2h is composed of an upper bottom portion 2i having a diameter G larger than the diameter E of the hanger hook 2 and a lower bottom portion 2j having a diameter H smaller than the diameter E of the hanger hook 2. Also, the third insertion portion 2h
Continues to a second insertion portion 2g having a cylindrical shape and an F diameter. The diameter F is the same as the diameter E of the hanger hook 2. Further, a first insertion portion 2f formed in a tapered shape is provided at a distal end portion of the second insertion portion 2g. That is, the relationship between the sizes of the respective diameters is H <E =
F <G.

A hook hole 6 into which the hanger hook 2 is inserted is provided at the upper center of the main body 1.
As shown in FIGS. 5 to 7, the hook hole 6 includes a large hole 6a near the entrance and a small hole 6b located below the large hole 6a. The Great Hall 6
The diameter of a is I, the diameter of the hanger hook 2 is E,
It is larger than the diameter F of the insertion portion 2g and smaller than the diameter G of the upper bottom portion 2i of the third insertion portion 2h. The small hall 6
The diameter of b is J, the diameter of hanger hook 2 is E,
It is larger than the diameter F of the insertion portion 2g and smaller than the diameter I of the large hole 6a. That is, the relationship between the sizes of the diameters is E = F <J <I <G.

A hanger is made by connecting the hanger hook 2 and the main body 1 as described above. The connection between the hanger hook 2 and the main body 1 is performed such that the linear portion 2b of the hanger hook 2 is inserted into the hook hole 6 of the main body 1 from its tip before the main body 1 is cooled and solidified.

In this embodiment having the above-described configuration, the hanger hook 2 is provided with the first insertion portion 2f having a tapered tip portion when the hanger hook 2 is inserted before the main body 1 is cooled and solidified. Therefore, the hanger hook 2 can be easily inserted into the hook hole 6 opened in the main body 1. The large hole 6a at the entrance of the hook hole 6 is wider than the small hole 6b, so that the hanger hook 2 can be easily inserted. The hook holes 6 are holes formed before the main body 1 is completely cooled and solidified. Even when the hanger hook 2 is inserted, the hook holes 6 inside the main body 1 are not solidified.

Further, since the second insertion portion 2g having a cylindrical shape continuing from the first insertion portion 2f is provided, the first insertion portion 2g is provided.
f into the hook hole 6
To be inserted vertically while guiding to the center.

Further, by forming the third insertion portion 2h into an inverted truncated cone shape, the hook hole 6 is pushed out along the wall surface of the third insertion portion 2h, and the pressure on the inner wall (P2 in FIG. 4) increases. At this time, the diameter G of the upper bottom portion 2i of the third insertion portion 2h
Is made larger than the diameter H of the lower bottom portion 2j, so that a step is formed between the hanger hook 2 and the third insertion portion 2h. Therefore, when the third insertion portion 2h advances to the depth of the hook hole 6, the pressure above the upper bottom portion 2i (P1 in FIG. 4) decreases. As described above, when the pressure of each part (P1 and P2 in FIG. 4) changes, an action (arrow F in FIG. 4) occurs in which a part of the main body 1 enters the upper side of the upper bottom part 2i. Then, when the main body 1 is completely cooled and solidified, a part of the main body 1 enters the upper side of the upper bottom portion 2i, and the hanger hook 2 does not come off in the form of being engaged by the third insertion portion 2h. Further, the upper bottom portion 2j of the third insertion portion 2h has a diameter G larger than the diameter E of the hanger hook 2 and is a surface projecting vertically from the center axis of the hanger hook 2, so that the hanger hook 2 faces upward. When trying to escape, the force that presses it is applied in the vertical direction, and the pressing force works to the maximum without dispersing. Therefore, the engagement between the hanger hook 2 and the main body 1 becomes strong.

Further, by providing a plurality of the third insertion portions 2h, each of the third insertion portions 2h has an independent upper bottom portion 2i and a lower bottom portion 2j according to the same principle as described above. Therefore, the engagement force between the hanger hook 2 and the main body 1 becomes stronger.

As described above, the engagement between the main body 1 and the hanger hook 2 can be enhanced only by inserting the hanger hook 2 before the main body 1 is cooled and solidified.

[0030]

[Effect of the Invention] As described above, in the present invention,
The first insertion portion facilitates insertion of the hanger hook into the main body. Further, when the hanger hook is inserted into the main body, the second insertion portion guides the hanger hook to be vertically inserted. Further, the pressure inside the hanger main body is changed by the third insertion portion, and a part of the main body enters the upper side of the step portion. Thereby, the hanger hook and the main body are engaged.

Further, by forming the third insertion portion into an inverted truncated cone shape, the pressure inside the main body is changed, and
Insert it over the insertion part. Further, since the side surface of the third insertion portion is oblique to the insertion direction of the hanger hook, the hanger hook is inserted smoothly. Furthermore, after cooling and solidification, the upper bottom is the surface that protrudes vertically from the center axis of the hanger hook, so when the hanger hook tries to pull out upward, the force that presses it is applied in the vertical direction, and the pressing force is applied. Works to the maximum without dispersal. For this reason, the engagement between the hanger hook and the main body becomes strong.

Further, by providing a plurality of the third insertion portions, the engaging force between the hanger hook and the main body is further increased.

Thus, the main body and the hanger hook can be engaged only by inserting the hanger hook before the main body is cooled and solidified. In addition, the molding process for fixing the hanger hook is simplified, and the manufacturing cost is reduced. Moreover, the engagement force between the hanger hook and the main body also becomes stronger.

Accordingly, the hanger hook can be easily and reliably attached to the main body.
