Description

Band coupling means

The present invention relates to a band fastening means, more particularly, to a fastening means for fastening two fastening objects such as two right and left cups of a brassiere through a band, The band wound around the band storage portion is automatically released at the time of the reverse rotation by the pushing operation of the release button portion so that the wearer can be released from the tightly worn general wearing state to the brassiere To a wearable state such as a state in which the wearer does not wear the wearer's body, or to make it easier to reverse.

The brassiere is a women's underwear that wraps around the breast. It supports and protects the breast, corrects the shape of the breast, and is generally made of stretchy fiber material.

In addition to the original function of protecting women's breasts, the brassiere has been equipped with a body correction function to enhance the appearance of clothes, and in consideration of this, brassieres having various designs and colors have been developed in recent years.

On the other hand, the conventional brassiere is emphasized in terms of the original function of supporting and protecting the breast or the body correction function, and it has been common that the brassiere is used in a state of tightly tightening the chest generally on the basis of the wear state.

Recently, researchers from American medical anthropologists Singer and Griesmaijier have published a study (1995, "Dressed to kill") that the longer the time to wear a bra, the higher the incidence of breast cancer.

According to this study, the difference in the incidence of breast cancer between women wearing a 24-hour bra and women not wearing at all is 125 times, and the most common reason for wearing a brassiere is the higher incidence of breast cancer, It is reported that the body temperature is increased.

In Korea, SBS Special (2009.12), according to participant experiments of participants in the broadcast program, women who did not wear bras for a month, the lymph flow is very active, Various side effects caused by a tightly worn brassiere were confirmed.

However, due to social prejudice regarding the wearing of brassiere, it was practically impossible to use brassiere itself.

Further, since the conventional bra is fastened at the back of the wearer, even if it is intended to keep the brace in a comfortable state by keeping the wearer in a comfortable state according to the surrounding environment, There is a problem that such an operation is almost impossible.

On the other hand, Korean Patent Registration No. 10-1285687 filed and registered by the inventor of the present invention discloses a fastening means which is configured to receive a position guide by the magnetic force of a magnet and can easily fasten the right and left cups of the brassiere, However, development of fastening means with improved user-friendliness has been urgently required.

In order to automatically release the band (B) at a time, a force for pulling the wound band outward or a force for releasing it to the outside is required. In the case of a brassiere, for example, when a user wears a bra This tension can be used as a tension. It is of course possible to provide an artificial restoring force by providing a separate spring member to the rotary drum portion 50 in addition to such a natural force.

As shown in the figure, the band fastening means 1 according to the present invention is characterized in that the housing detachment pin inserting / fixing part 11, on which the housing detachment prevention pin 90 is inserted and fixed, 10); A housing 20 in which a slot 22 is formed in a side portion of the housing so as to be slidable through one end of each of the housing release pins 80 and a shaft insertion groove 21 is formed in an upper center of the housing; A shaft 30 in which an upper end portion of the shaft 20 is inserted into the shaft insertion groove 21 of the housing 20 in the longitudinal direction and a first screw portion 31 having a spiral shape is formed along the upper and lower circumferences thereof; The shaft 30 is vertically passed through the center opening 41 and the relative movement between the shaft 30 and the spiral first screw portion 31 of the shaft 30 is formed at the inner periphery of the central opening 41 A rotator 40 having a helical second threaded portion 41-1 which is engaged in a state where it can be engaged, and a first latching portion 42 is formed along a circumference of the second threaded portion 41-1; A second latch portion 51 capable of engaging or disengaging with the first latch portion 42 of the rotator 40 is formed along the circumference of the upper portion of the upper surface of the latch gear 52, And a band storage portion (not numbered) for storing the band B together with the body 10 is formed at a lower portion of the housing 10, and the upper and lower presses of the housing 20 and the body 10 The band B is wound in a click-stop manner in the band storage portion during forward rotation by the action and the band B wound in the band storage portion during reverse rotation by the pushing action of the release button portion 80 And a rotating drum unit 50 to be pulled.

It should be understood that in the band fastening means 1 of the present invention, the position and orientation relationship is defined and described based on the state where the body 10 is positioned on the lower side and the housing 20 is positioned on the upper side something to do. This is a moving means in which the housing 20 slides up and down with respect to the body 10. The band is stably wound by the pressing operation of the housing 20 while the body 10 is fixed, This is because the reference position and direction are determined from the point that the band is stably released by the pressing operation.

 The body 10 has a substantially hollow cylindrical shape and serves to prevent rotation of the housing 20 which is fastened to the upper portion of the upper side and to prevent a deviation due to a spring 60 to be described later And covers the outer side of the rotary drum portion 50 so as to protect the band B accommodated in the band storage portion (not given a reference numeral).

In more detail, the body 10 includes a housing detachment pin inserting / fixing part 11 formed in a substantially horizontal direction on opposite upper side portions thereof, so that one end of the housing detachment preventing pin 90 is inwardly So that it can be completely fixed. At this time, the other end of the housing detachment prevention pin 90 exposed to the outside from the housing detachment prevention pin insertion fixing part 11 is inserted into the long hole 22 of the corresponding housing 20, 20 are slidable up and down with respect to the body 10.

One end of the housing detachment prevention pin 90 is fully inserted and fixed in the housing detachment pin insertion fixing portion 11 of the body 10 and the other end portion of the housing detachment prevention pin 90 is engaged with the elongated hole 20, The rotation of the housing 20 is prevented by the body 10 even when the shaft 30 and the rotator 40 are rotated as described later, The band B can be gradually wound in a click-stop manner, as will be described later by the pressing operation (direction P in Fig. 3) of the housing 20 with respect to the body 10 by the pushing- .

In the illustrated example, the two housing detachment prevention pin inserting and fixing portions 11 are formed to face each other. However, three or more detachment preventing pin inserting portions 11 may be formed at a predetermined distance in the circumferential direction And the present invention is not limited thereto.

A lower portion of the body 10 is formed with a space inwardly as opposed to an upper portion in which the housing detachment pin insertion and fixing portion 11 is formed and the lower portion of the rotary drum portion 50 is provided with a band- (Not given).

Here, the lower portion of the body 10 may be completely closed by the cap 70. [

The housing 20 has a cylindrical shape with an approximately open bottom and accommodates a shaft 30 as a winding hole for winding and unwinding the band B and a portion of the rotator 40 and the rotary drum portion 50, The body 10 can be slid up and down by the formation of the slot 22 as described above.

That is, as shown in the figure, a shaft insertion groove 21 is formed at the upper center of the inner side of the housing 20 so that the upper end of the shaft 30 can be inserted into the housing 20, .

In addition, a long hole 22 is formed in the longitudinal direction of the side wall of the substantially cylindrical housing 20 so as to be completely inserted into the housing detachment pin inserting / fixing part 11 of the body 10, And the other end of the housing detachment prevention pin (90) is engaged and fixed so as to be vertically slidable with respect to the body (10).

Although two long holes 22 are mutually opposed to each other in the illustrated example, three or more long holes 22 may be formed to be spaced apart from each other by a predetermined distance in the circumferential direction. It is a matter of course that they are formed correspondingly to the number of the fixing portions 11. [

The shaft 30 is in the form of a helical shaft having a first threaded portion 31 as a helical threaded portion along an outer periphery thereof and an upper end portion thereof is vertically inserted into the shaft insertion groove 21 of the housing 20 The lower side of the rotator 40 is fixed to the body 10 when the housing 20 is slid downward relative to the body 10 in accordance with the pressing operation of the housing 20 with respect to the body 10, And goes down through the central opening 41.

The first threaded portion 31 as a helical threaded portion formed on the outer circumferential edge of the shaft 30 has a second threaded portion 41 as a helical threaded portion formed at the inner periphery of the central opening 41 of the rotator 40 -1) in a state of being engaged with each other in the form of relative motion.

The rotator 40 has a shaft 30 which descends and ascends through the central opening 41 and a second threaded portion 41-1 in the form of a helical thread at the inner periphery of the central opening 41, Is engaged with the first screw portion 31 of the shaft 30 when the shaft 30 is lowered through the center opening 41 of the rotator 40, The up-and-down linear motion can be switched to the horizontal rotation of the rotator 40.

When the housing 20 is slid downward with respect to the body 10 in accordance with the pressing operation of the housing 10 and thus the shaft 30 is lowered, the spiral- The rotator 40 is rotated in the counterclockwise direction (normal rotation direction, C2 direction) on the plane which is the winding direction of the band B by the engagement of the second threaded portion 41-1 of the rotor 40 and the second screw portion 41-1 of the rotator 40, (See FIG. 4). The rotation in the normal rotation direction and the reverse rotation direction will be described later in detail.

Of course, the winding direction of the band B in the counterclockwise direction of the plane is intended to set the reference direction for one example, and the winding direction may be set to be clockwise. Here, in the present invention, the forward rotation direction refers to the winding direction of the band, and the reverse rotation direction refers to the band release direction.

The rotator 40 has a first latch portion 42 formed along the circumference of the lower surface thereof and engaged with the second latch portion 51 of the rotary drum portion 50 to be described later in the form of male and female threads, .

7, the pressing operation (P direction) of the housing 20 with respect to the body 10 (the direction of pressing the housing 20 with respect to the body 10) 4), the rotator 40 also rotates in the counterclockwise direction (forward rotation direction, C2 direction in FIG. 4) with the descent of the shaft 30. At this time, the first latching portion 42 The vertical surfaces of the second latch portions 51 are engaged with each other so that the two latch portions are also rotated counterclockwise together. Through this, the band is wrapped.

In contrast, when the pressing operation is released, the shaft 40 is lifted by the elastic force of the spring 60, so that the first latching portion 42 of the rotator 40 rotates in the clockwise direction The latch stopper 83 is engaged with the latching jaw portion of the third latching portion 52-1 of the latch gear 52 so that the second latching portion 51 of the lower latching portion 51 is fixed (Reverse rotation prevention), so that they do not rotate but become fixed together. 7, the guide surface of the first latching portion 42 of the rotator 40 is formed so as to fall over the guide surface of the second latching portion 51, so that the second latching portion 42 51 are fixed, but the first latch portion 42 is rotated clockwise. During this process, the band remains in its wrapped condition. When these up and down pushing and releasing operations are repeated, the band is continuously wound. On the other hand, when the directions of the guide surfaces of the first latch portion 42 and the second latch portion 51 and the engaging jaw portions are reversed, on the contrary, for example, the rotator 40 is rotated .

The rotatable drum portion 50 has a substantially hollow cylindrical shape and is inserted and fixedly inserted into an opening portion of the body 10 downwardly, And the second latching portion 51 is engaged with the first latching portion 42 of the first latching portion 42 to be engaged and rotated.

A latch gear 52 is formed on the outer circumferential surface of the upper portion of the rotary drum portion 50 so as to perform a click-stop winding and self loosening of the band B .

The upper portion of the upper portion of the rotary drum portion 50 having the latch gear 52 is protruded in a relatively laterally direction and the upper portion of the body 10 And the uppermost surface thereof is engaged with the first latching portion 42 of the rotator 40 by the second latching portion 51.

The latch gear 52 is rotated by the engagement rotation of the first latch portion 42 of the rotator 40 and the second latch portion 51 of the rotary drum portion 50 It is possible to rotate forward (counterclockwise rotation, C2 direction) together.

However, as shown in FIG. 4, the latch gear 52 has a guide surface inclined in one direction and a third latch portion 52-1 formed by a latching jaw, The latch stopper 83 of the unlocking portion 80 to be described later is guided without being caught by the guide surfaces of the respective third latch portions 52-1 and then engaged with the latch jaws in a one-stop manner And then is guided along the guide surface of the third latch portion and then caught on the latching jaw. In order to perform the regular pressing operation of the housing 20 with respect to the body 10, a click- The latch stopper 83 of the release button portion 80 is caught in the latching jaw in the reverse rotation direction (clockwise direction), thereby preventing reverse rotation. The guide surface of the latch gear 52 and the number of the latching jaws can be variously modified, so that it is possible to pass a plurality of latching jaws at once without being necessarily engaged in a one-stop manner.

As described later, when the pressing plate 81 of the unlocking portion 80 is pressed and the latch stopper 83 is lifted and separated from the engaging jaw, it is possible to automatically rotate reversely through the restoring force applied to the band, B) is automatically released.

5, between the lower outer side of the rotary drum portion 50 and the lower inner side of the body 10, a band (not shown) is formed in accordance with the normal and reverse rotation of the latch gear 52 of the rotary drum portion 50, (Not numbered) is formed so that the tape B is wound or unwound.
