Description

[Detailed Description of the Invention] <<Purpose of the Invention>> The present invention relates to a hanger made of a material such as a thermoplastic synthetic resin material, and includes:
In particular, it relates to the connection structure between the respective component members.

<Background of the invention> When this type of daily necessities such as hangers are offered to the market, the appropriateness of the price is required as well as the functionality and design. For this reason, products using synthetic resin as a material, which can reduce manufacturing costs and have excellent weather resistance, are currently becoming popular. However, depending on the connection structure of each assembly member that makes up this, it is not only difficult to manufacture the parts, but also requires time and effort to assemble the parts, increasing labor costs, etc., and ultimately making it impossible to reduce costs. become. Therefore, in this type of hanger, etc., various measures have been taken so that the structure of the members is relatively simple and the connecting parts between the members can be assembled in a so-called one-touch operation.

<Technical matters attempted to be developed> The present invention was also made as part of such efforts, and it is possible to assemble parts with one touch by skillfully utilizing the elasticity of synthetic resin, and once assembled. What was created was an attempt to develop a new structure that would not easily come off.

<<Structure of the invention>><Means for achieving the object> That is, the member connection structure in a hanger, etc., which is the first invention according to the present application, consists of a holding member and a member to be held, and the holding member has one end connected to the member to be held. A locking hook is formed facing in the opposite direction to the hanging direction, and the held member is provided with a locking portion that is externally fitted onto the locking hook, and a free end of the locking hook is provided with a locking portion that is externally fitted onto the locking hook. In this state, a regulating portion that maintains a gap smaller than the wire diameter of the locking portion faces the free end of the locking hook, and either or both of the locking hook or the restricting portion is bent. Accordingly, a gap is temporarily formed between the restricting portion and the free end of the locking hook to allow passage of the locking portion.

In addition to the above-mentioned requirements, the member connection structure of a hanger or the like according to the second invention of the present application has an insertion assisting notch in which only the locking hook is bent and the locking portion can escape above the free end of the locking hook. It is characterized by the provision of.

Furthermore, in addition to the first and second requirements, the member connection structure of a hanger, etc., which is the third invention of the present applicant, is such that, in addition to the first and second requirements, the free end of the locking hook faces perpendicularly to the plane formed by the regulating part. It is characterized by being formed as follows.

Each of these ideas attempts to achieve the above object.

<Operation of the device> In the first device of the present application, by bending the locking hook, a gap that allows the locking portion to pass is temporarily created between the regulating portion and the free end of the locking hook. Since the locking portion is formed, the locking portion can be locked to the locking hook with a single touch. In the free state of the free end of the locking hook, the gap between the free end of the locking hook and the regulating portion is smaller than the wire diameter of the locking portion, so that the free end of the locking hook does not come off easily.

Furthermore, in the second invention of the present application, an insertion assisting notch is provided above the free end of the flexed latching hook through which the latching portion can escape, so that the latching hook is only slightly bent. However, the gap between the free end of the locking hook and the restricting portion is in a state that allows the locking portion to pass through, so that the locking portion can be easily locked to the locking hook.

Furthermore, in the third invention according to the present application, since the free end of the locking hook is vertically lowered to the plane formed by the regulating portion, in the free state of the locking hook, this free end is located closest to the restriction part, and the gap between the locking hook and the restriction part is always widened when the locking hook is bent.

<Example> The present invention will be specifically described below based on the illustrated example. Although the present invention is applied to the hanger 1 as an example, it is not limited to the embodiments described below as long as it is a connecting part for the same purpose. First, the outline of the hanger 1 to which the present invention is applied will be described. This hanger body 3 is attached in a suspended state below a hanging hook 2, and this hanger body 3 has a hanger frame 4 having a rectangular frame structure, for example, and a large number of pinch points 5. is installed and configured. The hanging hook 2 and the hanger body 3 are, for example, a body hanging band 6 adjusted to a corner of the hanger frame 4.
A large number of the pinches 5 are hung from the hanger frame 4 by pinch bands 7. In addition, in the case of the hanger 1 of this embodiment, the hanging hook 2, the hanger main body 3, the main body suspension band 6, the pinch band 7, etc., which constitute the hanger 1, are made of plastic material except for the spring S in the pinch. Form. However, it may be constructed by appropriately combining metal materials and the like. Below the above hanger 1
The shape, structure, mutual connection structure, etc. of each member will be explained. First, the hanging hook 2 is a member that is directly suspended from the clothesline A, and has a rod hanging part 10 bent into a loop shape with a part open upward, and a flange 11 on the lower end side.
is formed, and the center of the lower surface side of the flange 11 is made to protrude downwardly from the suspension shaft 12. This hanging shaft 12 has an inverted claw part 13, and a slit 14 is formed in the center to allow the inverted claw part 13 to elastically move.
is configured to be able to bend to a reduced diameter state, thereby allowing the hanging hook 2 to be fitted into the holder 15 which is rotatably connected. That is, the holder 15 is approximately disk-shaped, and has a suspension shaft receiving hole 16 formed in the center of the holder 15, into which the suspension shaft 12 is inserted loosely enough to rotate.
For example, four holder hooks 17 are formed around it in an upwardly angular shape. The aforementioned hanging hook 2
The upper part of the body suspension band 6 is directly connected to the holder hook 17 of this holder 15.
and the upper locking portion 6a of the main body suspension band 6. That is, the main body suspension band 6 has locking portions 6a and 6b formed at its upper and lower portions, respectively, and has substantially the same annular shape. The locking portion 6a is attached to the holder hook 17 in a loosely externally fitted state, and after the hanger 1 is assembled, the locking portion 6a of the main body suspension band 6 is connected to the holder hook 17.
The gap formed between the tip of the holder hook 17 and the flange 11 of the hanging hook 2 is made smaller than the wire diameter of the locking part 6a so that the holder hook 17 does not slip out. Next, the connection structure between the main body suspension band 6 and the hanger main body 3 will be described, but first, the hanger frame 4 that constitutes the hanger main body 3 will be explained. The hanger frame 4 is a rectangular frame-shaped member made of plastic material, and its cross-sectional shape is approximately in the shape of an inverted channel with an open bottom. That is, the frame-shaped portion of the hanger frame 4 is the upper surface portion 2.
0, the outer surface portion 21, and the inner surface portion 22 form a reverse channel cross section, and a folding connection portion 23 is provided at approximately the center of the hanger frame 4, and the hanger frame 4 is foldable at the center. It is configured so that Further, the square frame-shaped hanger frame 4 integrally includes trident-shaped reinforcing beams 24 on both sides of the folding connecting portion 23 . In such a hanger frame 4, the connection portion of the main body suspension band 6 with the lower locking portion 6b is mainly constituted by locking hooks 25 formed at four locations on the hanger frame 4. That is, the locking hook 25 is designed to protrude inwardly and downwardly from approximately the center of the upper surface portion 20 of the hanger frame 4.
5 is provided with a connecting recess 26, which is shaped like a semi-cylindrical cutout of the inner side surface 22. The locking hook 25 extends inward in a slightly horizontal direction from near the upper end of the central part of the recess side plate 27 formed to partition the connection recess 26, and is further bent approximately 90 degrees from there to direct the free end side downward. It has a downward hook shape. And the free end 25a of the locking hook 25
further includes a contact portion 2 formed inside the hanger frame 4.
8, there is a slight gap inside the connection recess 26.
It is configured so that it faces G ⁰ . In this embodiment, the contact portion 28 is formed by extending the lower end edge of the inner side surface portion 22 of the hanger frame 4, and is formed in a state that bridges the outside of the connection recess 26. However, the shape is not limited to this. The lower locking portion 6b of the body suspension band 6 is loosely fitted into the locking hook 25 so that the hanger body 3 is suspended by the body suspension band 6. It is composed of Incidentally, in the case of such a connection structure, when a load is applied to the hanger main body 3, the lower locking portion 6b of the main body suspension band 6 bends the locking hook 25 upward and inside the partition frame. Applying a certain load, the locking hook 25
begins to bend in the direction in which it receives the load, but at a position where it has been bent to a certain extent, the free end 25a of the locking hook 25 comes into contact with the contact portion 28, thereby preventing the bending. This significantly increases the stress resistance of the hook 25, allowing it to withstand high loads. Next, a description will be given of the hanger frame 4 and the pinch band 7 to which the member connection structure for hangers and the like according to the present invention is directly applied. Incidentally, the holding member defined in the above registered claims essentially refers to the hanger frame 4 in this embodiment, while the held member refers to the pinch band 7, but various other connection structures for the same purpose may be used. Applicable to members. First, the pinch band 7 is made of a linear plastic material as shown in FIG. 6, and has locking portions 7a and 7b at its upper and lower portions, respectively. Note that the upper locking portion 7a is a simple ring, and the lower locking portion 7b has a partially cut-off ring-shaped structure. First, in order to support each pinch 5, the hanger frame 4 is provided with a large number of locking hooks 30, which specifically include the upper surface 20, outer surface 21,
It has a shape that protrudes from a partition-shaped part 31 formed to partition several places inside a frame forming a reverse channel cross section consisting of an inner side surface part 22. That is, as shown in FIG.
The free end 30a extends from the bottom of 1 in a substantially horizontal direction, and is further bent at 90 degrees from the end thereof.
is formed to face upward, and the upper end portion of the free end 30a is the upper surface portion 2 of the hanger frame 4.
It is configured so that it faces a position that maintains a constant gap G ₁ from the lower surface of 0. Note that the locking hook 30 extends from the base of the locking hook 30 with respect to the partition state 31,
A portion of the locking hook 30 where it begins to bend upward has a thick wall portion 30c with a larger cross-sectional diameter. Incidentally, such a thick part 30c has a strong structure suitable for supporting the downward load applied to the pinch band 7 when laundry is hung to dry, and when the pinch band 7 is locked, it is always It is bent from the bending portion 30d, and serves as a kind of reinforcing structure for the locking hook 30. The locking portion 7a of the pinch band 7 is such that the gap _G1 between the upper end of the locking hook 30 and the lower surface side of the upper surface portion 20 is expanded by temporarily bending the free end 30a of the locking hook 30. It is opened to allow the passage of the locking portion 7a, and is fitted into the locking hook 30. Once fitted, the locking portion 7a is constructed so that it will not come off the locking hook 30 unless an artificial load is applied, and the locking hook 30 has the function of preventing the locking portion 7a from coming off. 30
The portion of the upper surface portion 20 facing the free end side is defined as a restriction portion 20a. Further, in this embodiment, as defined in claim 2, a part of the upper surface part 20 of the regulating part 20a is cut out in the shape of a hole to form an insertion assisting notch 32, and the width of the notch is slightly reduced in connection with the insertion assisting notch 32. Narrowed insertion guide notch 3
form 3. Note that these effects will be described later. The pinch band 7 is a lower locking part 7.
It is connected to the spring S of the pinch 5 at b. Furthermore, in this embodiment, as shown in FIG. 8, a pair of spherical protrusions are formed on the inner side surface 22 of the hanger frame 4 to hold the pinch band so that the pinch band 7 can be sandwiched therebetween. 35 is formed. Incidentally, when adopting such a configuration, the pinch band 3 is
5 can be held facing inward, and a reasonable pinch state can be obtained.

In the hanger 1 to which the present invention is applied,
A locking portion 7a of the pinch band 7, which is a member to be held;
The mutual assembly work between the hanger frame 4, which is the holding member to which it is locked, and the integral locking hook 30 will be explained. As shown in FIG. 7a, this operation is performed by simply connecting the locking portion 7a of the pinch band 7 between the free end 30a of the locking hook 30 and the restricting portion 20a by manual or mechanical work by the operator.
All you have to do is push it into the gap G1 between the _two . When doing this, the upper end of the locking hook 30 bends due to the push, and as a result, the gap _G1 becomes smaller in size than in the free state as shown in FIGS. 7a and 7b. The size becomes larger, allowing the locking portion 7a to pass through, and the locking portion 7a of the pinch band 7 suddenly engages the locking hook 3.
It will fit within 0. In this embodiment, the locking hook 30 is configured to bend from the bending portion 30d, but as shown in FIG. , from this base part the locking hook 3
0 may be entirely bent. In this way the seventh
Although FIG. The position of the deflection does not matter as long as the gap G ₁ becomes substantially larger than in the free state and allows the locking portion 7a to be pushed in. When the locking portion 7a is fitted into the locking hook 30 and the insertion assisting notch 32 is formed in the regulating portion 20a, the free end 30a of the locking hook 30 is slightly bent, The locking portion 7a of the band 7 somewhat escapes into the insertion auxiliary notch 32, and the fitting operation for both is completed at once. Of course, if the guide notch 33 connected to the insertion auxiliary notch 32 is formed before this, the locking part 7a of the pinch band 7 will be actively guided by that part, making the insertion process easier. It is done smoothly. Of course, this guide notch 33 is not necessarily essential. In addition, the insertion auxiliary notch 32 and the guide notch 3
3, the upper surface 20 of the hanger frame 4 does not have to be completely open like a hole as in this embodiment, but can be formed as a recess as if the inside is partially cut away. may be formed. Note that, as in this embodiment, the free end 30 of the locking hook 30
It is preferable in the following respects that the insertion assist notch 32 and the guide notch 33 are provided in such a manner that a is directed almost vertically upward and the insertion assist notch 32 and the guide notch 33 are provided opposite thereto. That is, in the natural state of the locking hook 30, the locking portion 7a
The gap _G1 was so small as to prevent the passage of
As the locking portion 7a is inserted, the gap G1 widens, but due to the presence of the insertion assisting notch 32, even if the locking hook 30 is slightly bent, the gap _G1 will be expanded as the locking portion 7a is inserted.
It expands to the extent that it allows passage of a. Conversely, when trying to pull out the locked hook 30 by bending the free end 30a toward the side opposite to the partition-shaped portion 31, although the guide notch 33 is provided, the width of the locking hook 30 is Since it is considerably smaller than the diameter of the portion 7a, the locking portion 7a is hardly able to escape upward, and therefore the locking portion 7a cannot be removed unless the locking hook 30 is bent considerably. In this respect, the holding member structure provided with the insertion assisting notch 32 is easy to insert and difficult to remove. As can be understood from the above explanation, the present invention is a structure for connecting the locking portion 7a of the pinch band 7, which has an annular shape, as an example, to the hook-shaped locking hook 30, and is similar to the embodiments already described. The invention is not limited to this, and various modifications may be made.
First, FIG. 9b shows the free end 30a of the locking hook 30.
The free end 30a is tilted so that it opens from the vertical position, and when it is installed in this way, the free end 30a must be further tilted down using an appropriate jig J, etc. It is inserted by bending it in the direction. Further, based on the same technical idea, the embodiment shown in FIG. 9c has a free end 30a of the locking hook 30.
A bending auxiliary slit 30b is formed on the side so that the free end 30a can bend in the insertion direction, and can be applied when the material itself has a property that allows such bending. Furthermore, in the embodiment shown in FIG. 9d, the rigidity of the locking hook 30 is made relatively strong, while the corresponding restricting portion 20a of the hanger frame 4 is configured in the shape of a tongue as shown in the figure. , the structure is such that the regulating portion 20a side can be temporarily bent.

<<Effects of the invention>> Since the present invention has the configuration described above,
In this type of hanger, etc., the separately manufactured members can be instantly connected with one touch, and manufacturing efficiency can be improved. Furthermore, once the connected members are connected, they will not easily come off, so they can withstand even heavy loads such as laundry.
