Description

  The present invention relates to a hanger hook and a hanger that are attached to a hanger body so as to form a hook-like portion of the hanger.

  With respect to the hanger hook, as a conventional configuration for retaining the hanger so as not to fall off by being attached to the hanger body, as shown in FIG. 6, a hanger hook provided with a metal rod linear material is used. While the caulking 40 is applied to the end portion of the linear portion constituting the root portion so that a part of the end portion is crushed in the radial direction, the washer 41 is interposed to protect the through hole for mounting the hanger body, In general, the hanger hook is prevented from falling off from the mounting through-hole.

  In addition, as another configuration for giving the hanger hook a retaining function, the end portion of the straight portion constituting the root portion of the hanger hook provided by the metal rod wire material is a male screw, and a nut Threaded together, and if necessary, a washer is interposed to protect the through hole for attaching the hanger body, while removing the hanger hook from the through hole for attaching with a screw as a stopper A stop configuration can be used.

  On the other hand, as a conventional stopper, for example, a stopper composed of a hollow ridge and a rivet, and as a basic form, the hollow ridge includes a shaft portion having a hollow hole at a tip portion, The rivet includes a shaft portion and a head portion formed integrally with the base end of the shaft portion, and the shaft portion of the rivet includes the hollow portion. An outer diameter is set that is slightly larger than the hole diameter of the hollow hole of the rod, and the length of the shaft portion is set slightly shorter than the depth of the hollow hole (see Patent Document 1).

  The fixing form related to this conventional stopper is generally used as an adhering means having a function of preventing the removal of a knife, a handle of a scissors, etc. It can be applied as a form.

  However, applying the form of the conventional stopper as a form of retaining hook for a hanger provided with a metal rod linear material is generally because the metal rod linear material is long and thin. In order to press the rivet strongly into the hollow hole, it is not easy to drive it strongly and it is substantially difficult. That is, in the hanger hook, it is necessary to process the hook after assembling it to the hanger body, and there is a processing restriction due to the thin and long metal bar wire material. It is difficult to adopt the form of the tool. In addition, since the head of the rivet in the conventional stopper is small, it is necessary to protect the through hole for attaching the hanger body with a washer, so that it is not suitable as a structure for preventing the hanger hook from coming off. It is in form.

Japanese Patent Laid-Open No. 8-200334 ([0003] to [0004])

  The problem to be solved with respect to the hanger hook and the hanger is that it is difficult to use the conventional form of the stopper composed of the hollow rod and the rivet, and the end of the metal rod wire material constituting the hanger hook is difficult. In the form in which caulking is applied so that a part of the part is crushed in the radial direction or in the form of a fastener with screws, a washer is likely to be interposed, and the washer and nut are separated from the metal rod linear material.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a hanger hook and a hanger according to the present invention will be described in detail with reference to the accompanying drawings (FIGS. 1 and 2). This hanger hook 2 is provided so as to constitute a hook-like portion of the hanger, and is attached to the hanger body 1 so as to be prevented from coming off. As shown in FIG. It is comprised by the stop member 30. FIG.

  The hook body 20 includes a hook portion 21 formed by bending one side of a metal bar wire having a circular cross section, and a straight portion 22 linearly provided at a portion corresponding to the root continuous from the hook portion 21. The insertion portion 24 is provided with an insertion hole 23 formed in the axial center from the end face of the straight portion 22 and formed deeper than the length of at least the diameter of the metal rod wire. In the present embodiment, as shown in FIG. 2, the depth of the inserted portion 24 is about twice as long as the diameter of the metal rod wire.

  The retaining member 30 is provided in a form in which a shaft portion 33 is erected from a concave bottom portion 32 of a cap portion 31 formed in a cap shape, and the shaft portion 33 is inserted into the insertion hole 23 to be inserted into the insertion portion 24. Is applied by pressure from the direction intersecting the axis of the straight line 22 (in the present embodiment, the direction perpendicular to the axis (see the arrow in FIG. 2)), and the straight line of the hook body 20 is It is provided so that it may be fixed to the end surface part of 22. The caulking work can be efficiently performed by making a caulking die and using a press device. It can also be done manually with a tool based on the principle of leverage, such as large pliers.

  According to this, the hanger hook retaining structure provided with the metal rod wire material has a simple configuration that is easy to assemble, and can be made to have a clean appearance, so that a hanger with a good appearance and a higher-class feeling can be obtained. In addition to being able to be configured, it has a particularly advantageous effect of not forming a caulking portion that causes an acute angle portion or a burr. That is, according to the present invention, the inserted portion 24 is sufficiently strong so that the retaining member 30 is not pulled out from the straight portion 22 of the hook body 20 with a deformation that the crimped shape cannot be discerned with the naked eye. Can be fixed. Moreover, since the retaining member 30 with a large head (caps 31) can be used as in the present embodiment, a configuration that does not require a washer can be employed. For this reason, the appearance can be kept clean and a high-class feeling can be created. And since the cap part 31 is a spherical shape round form, it does not get caught in the cloth of clothes and does not injure a user.

  The retaining member 30 includes a cap portion 31 and a shaft portion 33 which are large heads, and a so-called decorative rod configuration widely used as a drum nail or a chair tension rod can be used. That is, the retaining member 30 is formed by cutting the nail-like pointed portion of the decorative rod, and the length of the shaft portion 33 is shorter than that of a normal decorative rod. Use it. Such a form of the retaining member 30 is already produced in large quantities at low cost as a decorative ornament, and since its manufacturing means can be easily applied, there is an advantage that it can be produced at low cost and can be easily obtained.

  Further, in this embodiment, as shown in FIG. 2, several grooves 34 are formed on the outer surface and the back surface (not shown) of the outer periphery of the shaft portion 33, so that the inserted portion 24 is pivoted at the time of crimping. The structure is such that the joining of the outer peripheral groove of the portion 33 is complemented. In addition, as a form which complements joining of the to-be-inserted part 24 and the axial part 33, in addition to the simple groove | channel 34 being formed, there also exists a meaning as reflection by forming the groove | channel 34, but an axial part Of course, a convex part may be formed in the outer periphery of 33, and an unevenness | corrugation may be formed.

Further, in this embodiment, the hole diameter of the insertion hole 23 is provided to be equal to or smaller than the diameter of the shaft portion 33, and the shaft portion 33 is inserted into the insertion hole 23 in a press-fit state. In addition, as described above, the shaft portion 33 is finally fixed to the insertion portion 24 by caulking the insertion portion 24 by applying external pressure from the direction intersecting the axis of the straight portion 22. Therefore, the strength with which the shaft portion 33 is press-fitted and fixed in the insertion hole 23 only needs to be sufficient to complement the fixation, and does not need to be strengthened beyond a certain level. Therefore, the relationship between the hole diameter of the insertion hole 23 and the diameter of the shaft portion 33 is only required that the hole diameter of the insertion hole 23 is equal to or slightly smaller than the diameter of the shaft portion 33. A convex portion may be formed on the outer periphery of the shaft portion 33 so as to be a portion having an outer diameter that is appropriately larger than the hole diameter of the insertion hole 23.
More specifically, at least a part on the back side of the insertion hole 23 is provided to be equal to or slightly smaller than the diameter of the shaft portion 33, and most of the insertion hole 23 from the inlet is the diameter of the shaft portion 33. For example, the configuration may be large enough to allow easy insertion. According to this, at the start of insertion of the shaft portion 33 into the insertion hole 23, it can be easily inserted without applying pressure, and can be fixed in the press-fitted state at the final stage of insertion, so that the press-fitted state can be appropriately maintained. Become.

  According to this, it is possible to easily fix the retaining member 30 to the straight portion 22 of the hook body 20 so as to have a certain strength or more by pushing the retaining member 30 lightly or with a pressure below a certain level into the insertion hole 23. it can. And, by inserting the inserted portion 24 (side peripheral wall), the retaining member 30 can be more securely fixed to the hook body 20 together with the fixing by the press-fitting of the shaft portion 33 described above. In this embodiment, the depth of the inserted portion 24 is formed longer than the length of the shaft portion 33, and the shaft until the end surface of the straight portion 22 hits the bottom surface of the concave bottom surface 32 of the shade portion 31. The part 33 is inserted into the inserted part 24.

  As a specific form, the insertion hole 23 having a length about twice the diameter of the metal rod wire having a circular cross section is formed. For example, if the diameter of the metal rod wire is 4 mm, the diameter of the insertion hole 23 and the shaft portion 33 is about 2 mm, and the depth of the insertion hole 23 is about 9 mm. And the length erected from the concave bottom portion 32 of the shade portion 31 of the shaft portion 33 is preferably set to be shorter than the depth of the insertion hole 23, and is set to about 8 mm, for example. Further, for example, the depth of the concave bottom portion 32 of the shade portion 31 is about 3 mm, the outer height of the bowl-shaped bulge of the shade portion 31 is about 5 mm, and the shell-like thickness of the shade portion 31 is 1 mm. Set to degree.

  According to this, the shaft portion 33 of the retaining member 30 is inserted into the insertion hole 23 of the straight portion 22 so that the tip of the straight portion 22 of the hook body 20 enters the bottom of the concave bottom portion 32 of the cap portion 31. It will be inserted and fixed. Therefore, when the retaining member 30 is fixed to the straight portion 22 of the hook body 20, when viewed from the side, the shaft portion 33 of the retaining member 30 can be seen hidden behind the shell-shaped outer shell of the cap portion 31. No state. In the present embodiment, the base portion of the shaft portion 33 at the bottom of the concave bottom portion 32 of the shade portion 31 is formed with a base portion that is thickly provided to reinforce the root of the shaft portion 33, The shaft portion 33 may be inserted into the insertion hole 23 so that the front end surface of the linear portion 22 contacts the bottom surface provided by the root portion.

  As described above, since the retaining member 30 is fixed to the straight portion 22 of the hook body 20, the retaining member 30 is securely fixed, and the outer peripheral portion of the cap portion 31 is in contact with the outer surface of the hanger body 1. By doing so (see FIG. 4), the stopper is suitably secured. At this time, as shown in FIG. 3 and FIG. 4, the outer peripheral surface of the straight portion 22 of the hook body 20 is in full contact with the entire inner peripheral edge constituting the mounting hole 1 a of the hanger body 1. The hook 2 is in a state of being stably attached to the hanger body 1. In this embodiment, the hanger body 1 is formed by blow molding and is resin-molded into an outer shell shape so as to be hollow (see FIG. 4), and is configured corresponding to the thickness of the outer shell shape. As described above, the outer peripheral surface of the linear portion 22 is in contact with the entire inner peripheral edge of the mounting hole 1a, and the hanger hook 2 is stably mounted. That is, according to this, it can prevent that the attachment hole 1a deform | transforms and can prevent that the mounting state of the hook for hangers loosens.

Moreover, in this invention, as shown in FIG. 2, the groove-shaped part may be provided in the outer periphery of the axial part 33. As shown in FIG. According to this, since the groove-shaped part provided in the outer periphery of the shaft part 33 is pressed and adhered to the inner peripheral surface of the inserted part 24 by caulking, the retaining effect can be enhanced.
In this embodiment, as shown in FIG. 2, by forming several grooves 34 on the outer and front surfaces (the back surface is not shown) of the outer periphery of the shaft portion 33, the shaft portion 33 is prevented from being rotated and removed. I'm trying to stop. That is, the inner peripheral surface of the inserted portion 24 can be pressure bonded to the front and back grooves 34 of the outer peripheral surface of the shaft portion 33 to enhance the effect.

  Furthermore, as shown in FIG. 5, a stopper portion 26 that prevents the hanger hook 2 attached to the hanger body 1 from shifting downward may be provided by caulking or the like. A washer 27 is disposed between the upper surface of the hanger body 1 and the stopper portion 26 and is interposed by the stopper portion 26 so as not to damage the mounting hole 1a of the hanger body 1.

  As another means for preventing the hanger hook 2 attached to the hanger body 1 from shifting downward, a bush 10 may be used as shown in FIG. According to this, the hanger main body 1 is formed hollow by blow molding, and the straight portion 22 of the hook main body 20 is inserted through the bush 10 into the upper mounting hole 1a provided on the upper side of the hanger main body 1. It is installed by doing. As shown in FIG. 8, the bush 10 includes a tip portion 11 to be inserted at the time of mounting, a plurality of slits 12 formed so that the tip portion 11 is narrowed, and a step of an upper mounting hole 1a. The outer peripheral groove 13 fitted to the portion 1b (see FIG. 7), the flange portion 14 exposed to the outside, and the bush center hole 15 are provided. When the bush 10 is attached to the upper mounting hole 1a, the hook 10 is hooked. The linear portion 22 of the main body 20 is provided so as to be inserted into the press-fit state. Moreover, the bush 10 of this embodiment is made of resin and is provided so as to have the same texture as the hanger body 1. The press-fitting relationship between the bush center hole 15 and the straight portion 22 of the hook body 20 is preferably a press-fit degree that allows the straight portion 22 to slide with an appropriate force. In other words, the hook body 20 is normally held in a fixed state with respect to the hanger body 1, and it is preferable that the hook body 20 be slidable when a required large force is applied. Therefore, the cap 31 can be brought into contact with the hanger body 1 when the clothes are put on, and the hook body 20 protrudes to the maximum, and when the hanger itself is stored, the hook body 20 is pushed down. It is in a form that can be done.

  As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
