Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag, and more particularly to a bag in which a male member is pushed into a female member and snap-engaged, and the male and female members can be unlatched by a press release operation.

There has been a long-felt need to provide a press release bag that is particularly easy to use, yet robust and reliable.

A buckle of the present invention is a male latch including a female member (14) having a tubular mouth (60) and a pair of latch arms (24, 24) inserted from the inlet into the tubular mouth of the female member. And a pair of latch arms provided at the tips of the pair of latch arms (48, 48) facing each other and cam surfaces (46, 46) facing each other that open and extend in a V shape from the hooks. A pair of holding shoulders (70) snap-engage with the hook portions (48, 48) of the male latch member when the pair of latch arms (24, 24) are inserted into the tubular mouth portion (60). , 70), and the female member is provided with an opening 75 that opens the back side of the tubular mouth (60) in a square shape toward the wearer's abdomen when the buckle is worn on the body. A buckle in which a rectangular release member (16) is fitted and closed in an opening (75), wherein the rectangular release member (16) has a female member mouth (6 0) Near the three sides is a flat member surface (80) that covers the peripheral edge of the rectangular opening (75), and the central part including the remaining one side is a semicircular finger-holding recess (28) that is deep enough to sink your fingertip. The linear center convex portion (84) extends vertically from the center of the peripheral wall of the finger hanging concave portion (28) toward the female member mouth portion (60), and the guide slot in the female member (14). There are latching disengagement arms (82, 82) extending in parallel from the same peripheral wall on the left and right sides of the central convex portion (84) passing through (72), and flexible elasticity from both side walls of this semicircular peripheral wall. The leg portions (86, 86) are extended laterally so as to engage and slide with the edges of the overhanging portions (74, 74) of the inner wall of the female member (14), and the finger hook recess (28) is formed. When pushed by the fingertip toward the female member mouth (60), the latch release arms (82, 82) push the latch arms (24, 24) of the male latch member to the left and right. It is characterized in that the buckle is disconnected.

The ease of use is that there is only one release member for the latch arm to be removed.

It is also particularly important in the bag of this invention that the release movement is in the longitudinal direction of the male latch member.
In known bags with only one press release, the release movement is perpendicular to the plane of the male latch member. That is, when such a known bag is used for fixing the end of the belt wound around the waist, the part of the bag is pressed toward the waist for release. However, this has the problem of pressing the lower back. Such a problem does not exist in the bag of the present invention.

It is preferable that each of the male latch member, the female member, and the release member of the present invention is a plastic one-piece molded product.

It is preferable that the male latch member and the female member each have a belt fixing device and have a shape that fits the wearer's body perfectly.

The male latch member may include a pair of flexible latch arms, the free end of each of which may include a cam surface and an undercut hook that abuts a complementary retaining shoulder in the female member. The cam surfaces may face each other. The male latch member may be provided with a pair of rigid arms that resist lateral movement of the male latch member when fully inserted into the female member.

The female member can include a latch arm and, if desired, a pair of outer grooves to receive the rigid arm. The central recess is separated from the outer groove by a wall that cooperates with the cam surface to deploy the latch arm during insertion of the male latch member. Another wall extending between the walls presents a retaining shoulder for the latch arm.

The release member may include a device to aid in manipulation, preferably such a device may be a thumb recess. The release member includes a pair of elastic members at one end of the release member cooperating with the slot through the other wall and further at the other end cooperating with the respective overhangs shown by the female member. It may be retained on the female member by the legs. The release member also disengages the latch arm from engagement with the retaining shoulder when the release member is slid longitudinally toward the male latch member,
It may include a pair of latch release arms cooperating with the latch arms.

It will be appreciated that the release member can be easily slid back and forth in the female member, but the range of this reciprocating movement is preferably on the order of 5 mm, and the movement in the direction of the release is the movement of the thumb or other finger. The subsequent opposite movement of the release member, which is carried out by pressure, is carried out by the insertion of a male latch member for connecting the buckle.

Embodiments of the bag of the present invention will now be described with reference to the accompanying drawings for illustrative purposes only.

Reference numeral 10 is a vehicle according to the present invention, and it can be seen from FIG. 1 and 2 that the vehicle 10 includes a male latch member 12, a female member 14, and a release member 16. The male latch member 12 and the female member 14 are preferably shaped so as to fit comfortably on the waist.

The release member 16 is now located on the underside, ie the back surface, of the bag 10 and is therefore normally invisible and hidden. The thing that looks like a circular transfer 18 on the upper surface of the female member 14 is a logo, which is not relevant to the present invention.

The male latch member 12 includes a belt fastening device 20, and the female member 14 also includes a belt fastening device 22. Each end of the belt may be looped around belt fastening devices 20 and 22 and then permanently fastened, for example by sewing, or temporarily fastened by tightening. The short end of the belt is the waist,
Tuck it between the rest of the belt to keep it out of sight.

The male latch member 12 has one or more flexible latch arms 24 (here two) that snap-engage with one or more retaining shoulders in the female member 14.

The bag 10 is released from the connected state of FIG. 1 to the separated state of FIG. 2 by pushing the release member 16 in the direction of arrow 26. This pushing force causes the release member 16 to move to the female member 14
Inside, the male latch member 12 is slid longitudinally to release the one or more latch arms 24 from the retaining shoulders.
Details of removing the latch arm will be described later.

The male latch member 12 may be a one-piece molding made of plastic, for example nylon 6.6, as shown in FIGS. 3-6, which may be a pair of side walls 40 connected by three horizontal bars 42.
including.

The belt fixing device 20 comprises the rods 42 and the openings between the rods. In FIG. 3, there is a series of ribs 44 on the upper surface of the left horizontal bar 42, and similarly there is a series of ribs 44 on the lower surface of the central horizontal bar 42. These ribs are to resist the slippage of the belt wrapped around it. However, assuming that the belt is not permanently attached to the male latch member 12,
Slip resistance is also obtained by the bevels and corners of the cross bar 42 having a series of ribs 44. See British Patent No. 2,020,729 granted to the applicant's parent company for specific details on how to secure the belt to the bag.

The horizontal bar 42 on the right has a pair of flexible latch arms as described above.
24, each of which has a cam surface 46 and an undercut hook 48 at its free end. The hook 48 need not necessarily be an undercut, but it is easier to hold it with a complementary holding shoulder provided in the female member. The cam surfaces 46 face each other, and the male latch member 12 is connected to the female member.
When inserted into 14, the latch arm 24 is opened outward. When fully inserted, the latch arm 24 snaps back to its original position, bringing the hook 48 into contact with the complementary retaining shoulder on the female member 14.

A pair of outer rigid arms 50 are also provided on the right lateral bar 42. The main purpose of this rigid arm 50 is to resist lateral movement of the male latch member 12 when the male latch member is fully inserted into the female member. However, an inclined guide surface 52 may be provided on the rigid arm 50 to help position the male latch member 12 into the female member 14 initially. Further, the rigid arm 50 also has a role of protecting the latch arm 24 when the male latch member 12 is erroneously operated.

The female member 14 is shown in FIGS. 7-10 and includes a plastic,
It may be, for example, a one-piece molded body of nylon 6.6, but two side cores are used for its molding.

The female member 14 has a belt fixing device 22 at one end, which has a structure similar to that of the male latch member fixing device 20 described above. The female member 14 has a flat tubular mouth portion 60 at the other end, into which the male latch member 12 is inserted. Mouth 60 defines three longitudinal projecting elements, an inner element having a tab at the tip to form a recess 64 and two outer grooves 62 on either side thereof for receiving latch arm 24 and rigid arm 50. Formed of a first side core with two outer elements. Each outer groove 62 is recessed by a wall 66.
Separated from 64. The outline of the first side core is shown by the dotted line in FIG. The lower side of the female member 14 is centered by a second side core shown in broken lines in FIG. The effect of this second side core is that the wall 68 with the retaining shoulder 70 is joined to the wall 66 and the extension of the recess is the wall.
The point is to make slot 72 through 68. First
As shown in FIG. 10, when the first side core and the second side core cooperate, a pair of opposed projecting portions 74 are formed on the lower side of the female member 14, which will be described later. Helps to hold 16.

It will be clear from FIG. 15 how the male latch member 12 and the female member 14 snap-engage. The latch arm
It is the initial sliding contact between the wall 66 and the cam surface 46 that causes the snaps to expand 24 until their hooks 48 can abut the retaining shoulder 70. It will also be appreciated that the rigid arm 50 is not fixed within the female member 14 but merely slides against the sidewalls of the outer groove 62 to resist excessive lateral movement of the male latch member 12.

Release member 16 is shown in FIGS. 11-14 and may be a one-piece molding made of plastic, such as acetal, some of which may be electro-discharge finished to show arrow 26 described above.

A thumb-shaped semi-circular recess 28 is formed centrally on one side of the flat surface 80 of the release member 16 and has a pair of latch release arms 82 projecting longitudinally therefrom, as well as a longitudinal extension on the peripheral wall thereof. There is a central ridge 84 present and a pair of laterally arranged elastic legs 86.

To assemble the release member 16 to the female member 14,
As shown in FIGS. 6 and 17, the convex portion 84 is inserted into the slot 72, and the elastic leg portion 86 is pushed in to snap-engage with the projecting portion 74.

Further, the lower portion 88 of the female member 14 is formed on the wall portion of the release member 16.
It is sandwiched between 80 and convex portion 84. A chamfered portion 90 may be provided at the front end portion of the convex portion 84 to facilitate insertion into the slot 72. Moreover, each overhanging portion 74 of the female member 14 is sandwiched between the wall portion 80 of the release member 16 and each elastic leg portion 86, and the free end portion of each elastic leg portion 86 preferably has a shoulder as shown in the drawing. The portion 92 is provided to have a shape that facilitates the holding.

To release the bag 10 from the connected state shown in FIG. 1, the release member 16 is slid to the left as shown in FIG. Then, the latch removal arm 82 becomes the cam surface of the latch arm 24.
When riding on 46 and further pushing the release member 16, the latch arm 24 bends outward and deforms, and is disengaged from the holding shoulder 70.

The forward / backward movement of the release member 16 is performed by the cooperation of the convex portion 84 and the slot 72, the elastic leg portion 86 and the protruding portion 74, and the surface 80 of the release member 16.
Are guided by contacting the lower side of the female member 14.

This invention has opened a new type of buckle that places the highest priority on reliability. Since the release member is on the back side of the buckle and is moved along the belt, there is no fear that the bag will come off due to a malfunction. Since the release member has a finger hooking recess for sinking the fingertip, when the thumb is inserted between the wearer's body and the bag and moved, the finger does not get in the way. The release member engages and slides in the female member by the left and right flexible elastic legs and the linear central convex portion at the tip, so even if the finger-holding concave portion is pushed slightly obliquely, it does not get twisted and smoothly. Slide.
