Description

  The present invention relates to a length adjusting mechanism around a skirt provided with a slide adjuster.

Conventionally, as a size adjusting mechanism of a hat or a sun visor, an adjuster and a rail using a belt, an American hook type, a hook-and-loop fastener, and the like are known.
The method using an adjuster and a rail is to adjust the size by sliding the adjuster on the rail, but it is not widely used at present. American Hook adjusts the size by combining a belt with a hole of about 7 holes and a belt with a hook and shifting the position where it fits into the hole.
If you use a hook-and-loop fastener, you can create a belt with the same fabric as the front fabric, and the texture of the cap will not be lost. However, the hook-and-loop fastener is generally weak against rainwater and moisture, and dust and the like are likely to adhere to it, and the bonding strength may be reduced.

  On the other hand, size adjustment is also performed by using a cap skin or part of the cap skin made of rubber without using a belt. If the entire bottle skin is stretchable, the functions of the bottle skin, such as sweat absorption, quick drying, and deodorization, may be impaired. When rubber is used for a part of the bottle skin, it is necessary to put a tack on the cap body or to use a stretchable fabric. In addition, the bonding strength of rubber is greatly changed over time and may be reduced.

  The present inventor relates to a slide adjuster that can be used for apparel such as hats, trousers, or skirts, where the appearance design is extremely important, and has an engagement claw for a buckle in a serrated engagement groove formed on the outer surface of the band. In the engaged and locked state, the band is accessible to the buckle but cannot be retracted, and in the slide adjuster of the buckle, the buckle is composed of an opposing bottom plate, a ceiling frame, and both side plates connecting the two. A buckle body having a band insertion space, and an engagement claw that is horizontally installed inside the ceiling frame and engageable with the engagement groove of the band on the lower surface of one end, and the other end is engaged And an operation plate serving as a pressing portion for releasing the operation plate, and the operation plate is supported by a connecting shaft that connects the both side plates at an intermediate point between the engaging claw and the pressing portion. A slide characterized in that it can swing around a point as a fulcrum, and is provided with a pair of latching protrusions on the outer surface of the band and the pressing portion that can pull the buckle and the band with the fingertips of one hand. An adjuster has been proposed (Japanese Patent No. 4005109: Patent Document 1).

Japanese Patent No. 4005109

When the slide adjuster described in Japanese Patent No. 4005109 is used, most of the parts are hidden inside a hat, trousers, skirt, or the like, but some members appear in the appearance of the clothing.
Thus, there is a need for a size adjusting mechanism that does not appear on the appearance of clothing such as a hat or sun visor, in order to increase the degree of freedom in design.
In other words, the present invention provides a size adjustment mechanism that can be used for clothing that has a very important appearance design.

The present invention is a length adjustment mechanism around the hem provided with a slide adjuster.
The slide adjuster is composed of a synthetic resin band and a buckle, and the engagement claw of the buckle is engaged with a serrated engagement groove formed on the outer surface of the band, so that the band can freely approach the buckle in the locked state.

The buckle is fixed to the back of the hem,
When the band and the buckle approach each other, the hem is shrunk, and when the band and the buckle are separated, the hem is stretched.

  The length adjustment mechanism has a length around the head of the hat or sun visor in which the circumference of the hem is the size element of the hat or sun visor (the crown bottom), and the buckle is fixed to the inside of the size element or the bottle skin An adjustment mechanism is preferred.

It is preferable that the length adjusting mechanism around the head of the hat or sun visor includes a visualizing means on a bottle skin at a portion where the band or buckle is located inside.
It is preferable that the band is exposed on the inner side of the original size (the surface that contacts the head).
It is preferable that the band has a length that makes one round along the inside of the size element.

It is preferable that a mark is marked on the cap body cloth corresponding to the pressing portion.
It is preferable that the cap body cloth corresponding to the pressing portion has an opening.

It is preferable that a sheath into which the front end portion of the band can enter is provided between the bottle skin and the size element.
In the bottle skin and / or the size element, it is preferable that a friction reducing sheet is provided at the entry position of the front end of the band.

Since a size adjusting mechanism such as a slide adjuster does not appear at all in the appearance, the degree of freedom is greatly increased in designing clothing such as a hat, and a high-class feeling can be added.
Since the slide adjuster has a light and simple structure, the size can be adjusted quickly and easily.

It is the perspective view seen from the upper right rear part of the cap drawn through seeing through the length adjustment mechanism around the hem which is the principal part of the present invention.

Hereinafter, an embodiment of a hat provided with a length adjustment mechanism around the hem according to the present invention will be described with reference to the drawings, but a sun visor provided with the adjustment mechanism also has the same purpose and effect as a sun visor. Is achieved.
FIG. 1 is a perspective view of a hat drawn through the length adjusting mechanism around the hem, which is a main part of the present invention, as seen from above the right rear part. "Lower part", also called "head circumference") 3, bottle skin (slip, also called size belt) 4 is shown.

  As will be described later with reference to FIG. 2, the slide adjuster 8 provided inside the cap includes a band 10 and a buckle 20, and the buckle 20 is fixed between the bottle skin 4 and the cap body 2. More specifically, the buckle 20 is fixed to either the bottle skin 4 or the cloth of the cap body 2. In addition, the band 10 is fixed to either the bottle skin 4 or the cloth of the cap body 2 with the attachment portion 7 except for the case where the band 10 has a length that goes around the inside of the size element 3 as described later. Is done. Since the band 10 and the buckle 20 can be provided at any position in the circumferential direction of the size element 3, a disengagement pressing portion 32 described later can also be provided at an arbitrary position of the size element 3. it can.

Next, the slide adjuster will be described with reference to FIG.
2 shows a slide adjuster composed of a band 10 and a buckle 20. FIG. 2 (1) is a plan view thereof, and FIG. 2 (2) is a longitudinal side view taken along the line zz of FIG. 2 (1). It is.

  In these figures, a serrated engagement groove 12 is formed on the outer surface of the band 10 having a required length, width and thickness from the tip (portion close to the buckle 20) to the end, and at the end of the band 10. Are provided with a number of mounting holes 16 for fixing the band 10 to the cap size 3 or the bottle skin 4.

  The buckle 20 is mainly composed of a flat and cylindrical buckle body 24 including a bottom plate 21, a ceiling frame 22 facing the bottom plate 21, and side plates 23 and 23 connecting the bottom plate 21 and the ceiling frame 22. The buckle body 24 is opened with the sliding direction of the band 10 as an insertion opening, and the inside thereof becomes an insertion space 26 of the band 10. In the present embodiment, the length of the bottom plate 21 in the longitudinal direction (sliding direction of the band 10) is made longer than the length of the ceiling frame 22 in the longitudinal direction, whereby the size plate 3 or bottle is formed by the mounting hole 27 formed in the bottom plate 21. The attachment to the skin 4 is facilitated, and the band 10 is smoothly inserted.

  On the inner side of the ceiling frame 22, an operation plate 30 having a size that fits therein is installed horizontally. An engaging claw 31 that can be engaged with the engaging groove 12 of the band 10 is provided on the lower surface of one end of the operation plate 30, and the upper surface of the other end serves as a pressing portion 32 for releasing the engagement.

  A connecting shaft 35 is formed at an intermediate point in the longitudinal direction of the operation plate 30, and this connecting shaft 35 is connected to the upper inner walls of the side plates 23, 23. The cross-sectional shape of the connecting shaft 35 can be circular, elliptical, or other various shapes. The connecting shaft 35 may pivotally support the operation plate 30 and may have any shape that is not damaged by repeated swinging. Note that the connecting shaft 35 is not limited to the side plates 23 and 23, and even if it is supported on two sides of the ceiling frame 22 facing the operation plate 30, it can exhibit the same operation as described below.

  In the operation plate 30 of the present invention, the lateral width between the pressing portion 32 and the connecting shaft 35 is set as narrow as possible as long as the swing and strength of the operation plate 30 are satisfied. , 22, projecting portions 28, 28 as regulating members extend inward in the horizontal direction. This restricting member is a member for restricting the force in the vertical direction from acting on the pressing portion 32 inadvertently.

In the embodiment shown in FIG. 2, one end of the operation plate 30 (the side on which the engaging claws 31 are provided) is connected to the inner walls of the opposite side plates 23, 23. The connection is made by bent connection members 36, 36 extending from the corners of the operation plate 30. When the pressing portion 32 is pushed down and then the finger is released from the pressing portion 32, the operation plate 30 is returned to the original horizontal position. It is easy to restore to the state. Accordingly, various other shapes such as corrugated plates can be applied as the shape of the connecting member 36. In other words, the connecting member 36 has a function as a damper for the swinging motion of the operation plate 30.
The operation plate 30 and the side plate 23 may be connected to each other on the side opposite to the pressing portion 32 with the connection shaft 35 interposed therebetween, or may be a side edge portion of the operation plate 30 other than the one end portion. Instead, it may be connected to the ceiling frame 22.

The protrusion 33 provided at one end of the operation plate 30 (the side where the engagement claw 31 is provided) is a stopper for preventing the pressing portion 32 of the operation plate 30 from being pushed down more than necessary when the engagement is released. .
Further, the reference numeral 34 also contacts the side surface of the overhanging portion 28 when the pressing portion 32 is pressed down (see FIG. 2 (3)), the pressing portion 32 is pressed down more than necessary, and the operation plate 30 hits the upper surface of the band 10. It is a stopper for preventing the above. It is sufficient that one of these stoppers 33 and 34 is provided.

  The band 10 and the buckle 20 can be molded from a flexible synthetic resin. By making the band 10 made of synthetic resin, the band 10 can be smoothly inserted between the bottle skin 4 and the size element 3. That is, the synthetic resin has higher rigidity than the bottle skin 4 and the fabric (fabric, woven fabric) of the size base 3, so that the band 10 can be easily inserted.

  The buckle 20 is preferably molded from an elastic synthetic resin such as polyacetal, polyoxymethylene, polyamide, or polycarbonate because the operation plate 30 needs to swing around the connecting shaft 35. The buckle 20 is composed of a small number of parts and can be easily integrally formed with a mold because of its simple structure.

Next, the operation of the size adjustment mechanism shown in FIG. 1 will be described.
To adjust the size of the hat, with the fingertip of one hand in the state of not wearing the hat, the position corresponding to the band 10 in the size source 3 (or bottle skin 4), and sliding inward with the fingertip of the other hand The size source 3 (or bottle skin 4) provided with the adjuster 8 may be held and both hands may be brought close to each other.
FIG. 3 is a perspective view showing a state in which the circumference of the skirt of the cap is contracted at this time, and it is shown that a collar 6 is formed on the size element 3 and the cap body 2 near the slide adjuster 8.

  By this operation, the size of the hat can be adjusted to be small. However, even if both hands are pulled apart, the size of the hat is not increased by the action of the slide adjuster 8. In order to increase the size of the hat, that is, to extend the size element 3, the size element 3 or the bottle skin 4 corresponding to the portion where the pressing portion 32 of the slide adjuster 8 is hidden may be pressed with a fingertip or the like.

FIG. 4 is a rear view of a cap provided with the size adjusting mechanism of the present invention.
In the embodiment of FIG. 4 (1), the slide adjuster 8 is completely hidden inside the cap body 2 and does not appear in the appearance.
In the embodiment of FIG. 4B, the mark 40 is marked on the cloth of the cap body 2 corresponding to the portion where the pressing portion 32 of the slide adjuster 8 is hidden.
In the embodiment of FIG. 4 (3), the opening 41 is provided in the cloth of the cap body 2 corresponding to the pressing portion 32 of the slide adjuster 8, and the state in which the pressing portion 32 appears from the opening 41 is shown. Yes.

  Next, the operation of the slide adjuster will be described. FIG. 2 (2) shows a state where the band 10 is inserted into the insertion space 26 of the buckle 20, and the engagement claw 31 of the buckle 20 is engaged with the engagement groove 12 formed on the outer surface of the band 10. ing. The engagement groove 12 has a sawtooth cross-sectional shape in the sliding direction, that is, a tapered surface that gradually becomes deeper in the traveling direction of the band 10 and a wall surface that rises substantially perpendicularly from the deepest position.

  When the band 10 is made to enter the insertion space 26 of the buckle body 24 from the pressing portion 32 side (left side in FIG. 2 (2)), the upper surface of the band 10 comes into contact with the engagement claw 31 of the operation plate 30. It advances while pushing up one end of the operation plate 30 (the side where the engaging claws 31 are formed), and the approach / separation position of the band 10 with respect to the buckle 20 is adjusted. In this state, as shown in FIG. 2 (2), since the engaging claw 31 is engaged with and locked with the predetermined engaging groove 12, the band 10 can be advanced with respect to the buckle 20, but is retracted. It is impossible.

  On the other hand, in order to retract or pull out the band 10 from the buckle 20, if the pressing portion 32 of the operation plate 20 is lightly pushed down with a finger, the operation is performed around the connecting shaft 35 as shown in FIG. As a result of the rotation of the plate 30, the engaging claw 31 located on the opposite side is lifted and the engaging claw 31 is detached from the engaging groove 12, so that the band 10 can be freely slid. When the finger is released from the pressing portion 32, the pressing portion 32 returns to the original horizontal state due to the elasticity of the synthetic resin.

  In the present invention, the slide adjuster 8 is not limited to the one having the above-described structure, and an engagement groove is provided in the band, and a hook of a buckle is elastically engaged with the groove, and the slide adjuster 8 operates in a direction substantially perpendicular to the band. Any structure may be used as long as it is a slide adjuster composed of a buckle and a band that can release the locked state at any time by a push button.

In the embodiment of FIG. 2, the buckle body 24 includes the bottom plate 21, the ceiling frame 22, and the side plates 23 and 23, but the ceiling frame 22 does not necessarily require all four sides, and the connecting shaft 35. Both sides may not be two sides or any one side.
Moreover, the ceiling frame 22 itself is not necessarily required. In the case of the buckle body 24 in which the ceiling frame 22 is omitted, the insertion space 26 for the band 10 is formed by the bottom plate 21, the side plates 23 and 23, and the connecting shaft 35. The insertion space 26 can also be formed by the connecting members 36 and 36.

  In the present invention, a sheath (not shown) through which the front end of the band 10 can enter may be provided between the bottle skin 4 and the size base 3 in order to smoothly perform the above-described size adjustment operation. In the bottle skin 4 and / or the size element 3, a friction reducing sheet (not shown) may be provided at the entry position of the front end of the band 10. As a result of the front end portion of the band 10 being guided by the sheath and entering along the friction reducing sheet, the insertion of the band 10 becomes smooth.

  In the embodiment shown in FIG. 1, the cap type cap has been described, but the cap size adjusting mechanism according to the present invention can also be applied to hunting and the like. In this case as well, like a cap-type cap, a tuck or a bag is put on the fabric (size 3) and the bottle skin 4 of the skirt of the cap body 2 to which the slide adjuster 8 is attached.

In the hat provided with the bottle skin 4, the length of the size element 3 can be adjusted by providing the means for visualizing the band 10 or the buckle 20 on the bottle skin 4 where the band 10 or the buckle 20 is located inside. Can be easily.
FIG. 5 is a partial plan view of the skin 4 provided with the visualizing means. In this embodiment, the visualizing means is constituted by the through holes 5. As shown in FIG. 5, if a plurality of through holes 5, 5... Are provided according to the width of the bottle skin 4, the position of the band 10 or the buckle 20 hidden inside can be visually recognized. At this time, if the bottle skin 4 and the band 10 or the buckle 20 are different in color, it becomes easier to visually recognize.
As a visualizing means, the through holes 5, 5... May be elongated slits, and the bottle skin 4 may be transparent or translucent.

In the length adjusting mechanism around the head of the hat of the present invention, the bottle skin 4 is not necessarily provided. In the case where the bottle skin 4 is not provided, the buckle 20 (or the band 10 and the buckle 20) is fixed to the size base 3, and therefore, when the slide adjuster 8 is contracted, that is, in a state where the cap is attached. The band 10 is in contact with the head, but the size element 3 is not in contact, and a gap is formed between the head and the size element 3, so that the person wearing the hat can easily feel a cool feeling. In addition, since the contact portion with the hair is also a limited region, even if the hat is worn, the disturbance of the hair can be significantly reduced.
The same effect can be obtained by not providing the bottle skin 4 only on the portion where the band 10 is located, or even if the bottle skin 4 is provided around the head, only the band 10 constituting the slide adjuster 8 is placed on the surface of the bottle skin 4. It can also be achieved by exposing it to (the surface in contact with the head).

In the above description, the length of the band 10 has been described on the premise of a length sufficient as a length adjusting mechanism. However, in another embodiment of the present invention, the band 10 is placed inside the size element 3. In addition to the cool feeling effect and the hair disturbance preventing effect, it is possible to enjoy the effect that it is not necessary to form the heel 6 or the tack on the hat.

  As described above, the embodiment relating to the hat size adjustment mechanism has been described. However, the size adjustment of the clothing item having the same function and function is also provided in the sun visor, the bottom part of the trousers, the waist part, and the waist part of the skirt by interposing the slide adjuster. A mechanism can be configured. Moreover, about a hat, it can apply widely, such as a cap and hunting. Furthermore, it can be applied to the mouth of an eco bag or the like.
