Technical field

The present invention relates to a clip for releasably connecting two parts or members, for example as a clip for releasably connecting a pouch to a backpack.

Background technique

As shown in FIG. 9 , sometimes a climber or hiker wants to attach a small pocket 100 to the side of a backpack 200 for putting some useful small items therein, for example. Heretofore, to attach the pouch 100 to the backpack 200, the clip 300 described in Japanese Patent Application Laid-Open No. 2002-119322 has been used, which is reproduced in FIG. 10 for convenience herein.

The clip 300 includes a plate-shaped clip base 310 and a plate-shaped cover 320 rotatably mounted on one end of the clip base 310 . The clip base 310 has a pair of cutouts 311 formed through itself and a pair of locking claws 312 , one locking claw 312 is provided on each side of the other end of the clip base 310 . The cover plate 320 has a U-shaped profile and has a pair of arms 321 with a pair of locking holes 322 formed through respective one ends for interlocking engagement with the locking claws 312 .

To attach the pouch to a backpack with such a clip 300 , the user first inserts the strap 110 attached to the pouch through the two cutouts 311 of the clip base 310 . Thereafter, the strap attached to the backpack is clamped between the clip base 310 and the cover plate 320 , and the locking claw 312 is brought into locking engagement with the locking hole 322 .

In order to release the pouch from the backpack, in other words, to release the clip 300 from the strap of the backpack, it is necessary to disengage the locking pawl 312 from the locking hole 322 . In order to do this, the respective outer sides of the two arms 321 of the cover plate 320 must be pressed inwardly with fingers to loosen the engagement of the locking claws 312 with the locking holes 322, and then the cover plate 320 is turned to leave the clip base plate 310.

US Patent No. 6145169 discloses another conventional clip 300A of similar structure, which is reproduced in FIG. 11 for convenience herein. In this known clip 300A, the clip base 310 has a pair of locking claws 313 and the cover plate 320 has another pair of locking claws 323 for locking engagement with the locking claws 313 . Each locking claw 313 is connected to the clip base 310 through the elastic connecting arm 314 in such a way that the deformation of the elastic connecting arm 314 causes the locking claw 313 to displace inward. The method of use and operation of the clip 300A is substantially the same as the clip 300 previously described. In order to disengage the locking pawl 313 from the engagement with the locking pawl 323, the user must press the opposite outer sides of the far end of the clip base 310 with his fingers, so that the elastic connecting arm 314 is deformed inwardly, thereby disengaging the locking pawl 313 from the engagement with the locking pawl 323. Engagement of the locking pawl 323. After locking pawl 313 is out of locking engagement with locking pawl 323 , cover plate 320 must be rotated away from clip base 310 .

In the above-described clips 300, 300A, in order to disengage the locking claws 312, 323 from the locking holes 322 and the locking claws 313, it is necessary to press the cover plate 320 and the clip base 310 on both outer sides thereof so that the arms 321 and The elastic arm 314 deforms. Arm 321 and resilient arm 314 are integrally molded to cover plate 320 and clip base 310, respectively. Moreover, since the cover plate 320 and the clip base 310 are molded by plastic into a plate-shaped profile with a relatively large thickness. They are difficult to press inwards. Therefore, a relatively large pressing force is required to deform the arm 321 and the elastic arm 314 enough to disengage the locking claws 312 , 323 from the locking holes 322 , and the locking claws 313 , respectively. However, the material and shape of those parts, especially the thickness of those parts, cannot be sacrificed for easier pressing of the clip base 310 and cover plate 320, because the clip base 310 and cover plate 320 must be molded from a strong plastic resin to thickness and width A relatively large plate profile to ensure sufficient strength for various purposes and to form locking claws 312 , 323 , locking holes 322 and locking claws 313 on the clip base 310 and cover plate 320 .

Also, in the clip 300 shown in Japanese Patent Application Laid-Open No. 2002-119322, a cover plate 320 rotatably mounted on a clip base 310 has two arms 321 to be pressed together. In order to disengage the locking claw 312 from the locking hole 322 , the user must rotate the cover 320 on the clip base 310 while pressing the opposite outer sides of the cover 320 with fingers. As introduced before, pressing the two outer sides of the cover plate 320 requires a strong force. Therefore, it is difficult to perform two operations of rotating the cover plate 320 and pressing the cover plate 320 simultaneously smoothly.

The operations of the clips 300 and 300A described in Japanese Patent Application Laid-Open No. 2002-119322 and U.S. Patent No. 6,145,169 respectively require a strong force, so the operations of these clips 300 and 300A are difficult and therefore the use of the clips 300 and 300A are greatly restricted.

It is therefore an object of the present invention to provide a clip which is easy to use and handle and which is very robust.

Further objects and advantages of the invention will become apparent from the accompanying drawings and the ensuing description.

The sliding members 6A, 6B are slidable between their locking position and the unlocking position, wherein the locking position is the position where the locking part 7 is locked and engaged with the locking lever 5, and the unlocking position is where the locking part 7 is disengaged from the locking lever 5. 5 in the locking engaged position.

As better shown in Figure 1, the clip base 2 is a substantially rectangular plate made of plastic. The clip base 2 includes a base body 21 adapted to be attached to the strap 110 of the pouch 100, and a receiving portion 22 provided on a distal end of the base body 21 and adapted to slidably accommodate the sliding members 6A, 6B therein. Base body 21 has a pair of mutually parallel spaced elongated ridges 23 disposed along the length of clip base 2 and adapted to support strap 110 of sachet 100 thereon.

As shown in FIG. 3 , the receiving portion 22 has a cavity 24 formed to penetrate in the lateral direction of the clip base 21 . The cavity 24 is a rectangular parallelepiped space closed by inner walls. The cavity 24 has a pair of end openings 241 formed at respective ends of the receiving portion 22, a pair of main openings 242 formed through the front wall and the rear wall of the receiving portion 22, and a pair of main openings 242 formed through the receiving portion 22 and along the base body 21. An incision 243 is provided on the distal side. The cavity 24 has a pair of guide walls 244 formed on opposite inner sides thereof. The cutout 243 merges with the inner guide wall 244 of the corresponding cavity 24 to form a retaining groove 245 communicating with the cavity 24 . The guide wall 244 merging with the groove 245 bends outward as it moves away from the opposite end of the groove 245 such that the cavity 24 gradually widens as the guide wall 244 approaches the end opening 241 . This is for easier insertion of the slide members 6A, 6B into the cavity 24 .

The cover plate 3 has substantially the same shape as the clip base 2 and is made of plastic. As shown in FIG. 1 , the proximal end of the cover plate 3 is rotatably mounted on the proximal end of the clip base 2 . The cover 3 includes a cover base 31 adapted to be attached to the strap 210 of the backpack 200, and a cover end 32 disposed on a distal end of the cover base 31 and having a locking bar 5 vertically formed thereon. . The cover base 31 has a holding piece 33 provided at its proximal end and extending toward its distal end in a direction parallel to the cover base 31 , and a small gap is defined by the holding piece 33 . The small gap is suitable for passing the straps 210 of the backpack 200 therethrough.

The hinge mechanism 4 comprises a sleeve 41 arranged at one end or the proximal end of the clip base 2 and extending transversely thereto, a supporting pin 42 rotatably engaged in the sleeve 41 and a support pin 42 arranged on each side of the proximal end of the cover plate 3 . And a pair of pin supports 43 adapted to hold respective ends of the support pin 42 such that the cover plate 3 is rotatably mounted on the proximal end of the clip base 2 .

The locking lever 5 is disposed on the distal end of the cover plate 3 opposite to the clip base 2 , and includes a handle 51 extending substantially perpendicularly from the cover plate 3 and an arcuate locking pawl 52 disposed at the distal end of the handle 51 . The locking pawl 52 has a pair of locking surfaces 53 formed on its rear side or on the side opposite to the cover plate 3 . The locking surface 53 is disposed in spaced parallel relationship to the front surface of the cover plate 3 .

As shown in FIG. 2, the sliding members 6A, 6B have the same structure and are made of plastic. The sliding member 6A includes a rectangular sliding body 61 and an elastic leg 62 integrally formed on one end of the rectangular sliding body 61 as a urging means in such a manner as to extend coplanarly with the rectangular sliding body 61 .

The rectangular sliding body 61 of the sliding member 6A has a rectangular first opening 63A formed through its center; a raised stopper step 64 formed on the other end of the sliding body 61 and extending in the transverse direction of the first opening 63A; formed as A slit 65 passing through the slider 61 and extending along the length of the first opening 63A; a holding protrusion 66 formed on the side of the rectangular slider 61 alongside the slit; a slightly recessed press formed on the other end of the slider 61 The surface 67 and a fitting protrusion 68A formed on one end of the first rectangular opening 63A and protruding on the same side as the stopper step 64 protrudes. The retaining protrusion 66 is adapted for retaining engagement with the retaining groove 245 of the cavity 24 .

Likewise, the sliding member 6B has a second oblong opening 63B, a second fitting protrusion 68B, and other portions identical to those of the sliding member 6A.

The elongated elastic legs 62 of the slide members 6A, 6B extend obliquely and gently bend from one side of the slide body 61 to the other and terminate at rounded or spherical ends 62'.

As shown in FIG. 3 , the sliding members 6A and 6B overlap each other in lateral alignment, and their respective fitting protrusions 68A and 68B fit into the second opening 63B and the first opening 63A of the sliding members 6B and 6A, respectively. Thereafter, the slide members 6A and 6B are inserted into the cavity 24 with their holding protrusions 66 opposed to the holding grooves 245 of the cavity 24 . When the overlapping sliding members 6A and 6B are inserted into the cavity 24 , the longitudinal sides 611 of the sliding members 6A, 6B slide along the inner guide wall 244 of the cavity 34 .

The circular end 62' of the resilient leg 62 of each sliding member 6A, 6B inserted into the cavity 24 presses against the step wall 641 of the stop step 64 of the other sliding member 6B, 6A, pushing the sliding member 6A forward, 6B goes into the locked position. When the pressing surfaces 67 , 67 of the sliding members 6A, 6B are pressed, the sliding members 6A, 6B come closer to each other, that is, the overlap therebetween in the longitudinal direction becomes larger. When the sliding members 6A, 6B approach each other, the elastic leg 62 of each sliding member 6A, 6B is pressed by the stepped wall 641 of the other sliding member 6B, 6A and thus elastically deformed. After the pressing force is released, the slide members 6A, 6B move away from each other or reduce the overlap therebetween in the longitudinal direction under the elastic action of the thus deformed elastic legs 62 . The slide members 6A, 6B can be brought closer to each other by pressing against the respective pressing surfaces 67 .

The locking portion 7 is provided when the slide members 6A, 6B overlap. Specifically, when the sliding members 6A, 6B overlap; the inner end surface of the first opening 63A serves as the first clamping surface 71A; the inner end surface of the second opening 63B serves as the second clamping surface opposite to the first clamping surface 71A. The tightening surface 71B; the locking opening 72 jointly defined between the first and second clamping surfaces 71A, 71B and the inner side surface of the first opening 63A constitute the locking portion 7 .

When the pressing surface 67 of the sliding member 6A, 6B is pressed against the elastic force of the elastic leg 62, the sliding member 6A, 6B approaches each other and enters an unlocked position where the first and second clamping surfaces 71A, 71B are separated from each other and The locking opening 72 widens. When the pressing force is released, under the elastic force of the elastic leg 62, the sliding members 6A, 6B are separated from each other and return to the locked position, where the first and second clamping surfaces 71A, 71B are close to each other and locked. The tight opening 72 narrows so that the locking portion 7 is in locking engagement with the locking lever 5 .

Now, how to attach the small pocket 100 to the backpack 200 using the clip 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 , 4 and 5 .

As shown in FIG. 1 , the clip 1 should assume a disengaged configuration, ie the locking bar 5 should not be in locking engagement with the locking portion 7 . The clip base 2 is inserted through the rear side of the pouch 100 and between the strap 100 of the pouch 100 so that the clip 1 is attached to the pouch 100 . The strap 210 of the backpack 200 is inserted between the holding piece 33 and the cover plate 3 .

Thereafter, the user rotates the cover 3 in a direction approaching the clip base 2 until the locking pawl 52 of the locking lever 5 locks and engages with the locking opening 72 , as shown in FIG. 4 . Thereafter, the rear side of the cover plate 3 or the side of the cover plate 3 away from the locking rod 5 and the rear side of the receiving portion 22 of the clip base 2 are pressed with fingers.

Since the surface of the locking pawl 52 is arcuate, such a pressing force presses the first and second clamping surfaces 71A, 71B of the sliding members 6A, 6B away from each other, thereby widening the locking opening 72, and the sliding member 6A, 6B reach the unlocked position. When the sliding members 6A, 6B reach the unlocked position, the locking pawl 52 is inserted into the locking opening 72 as shown in FIG. 5 .

Because the shank 51 of the locking rod 5 is narrower than the widest part of the locking pawl 52; once the locking pawl 52 is completely inserted through the locking opening 72, the first and second clamping surfaces 71A, 71B are immediately in contact with the elastic legs. 62 move toward each other under the action of the elastic force, so the sliding members 6A, 6B reach the locked position. When the sliding members 6A, 6B reach the locked position, the first and second clamping surfaces 71A, 71B clamp the handle 50 on opposite sides of the handle 50, and the front side of the mating protrusion 68A of the sliding member 6A and the sliding member 6B The rear side of the corresponding end of the locking pawl 52 is engaged with the abutting surface 53 of the locking pawl 52, thereby holding the locking pawl 52 therein. Thus, the locking lever 5 is in locking engagement with the locking opening 72 . At this time, because the elastically deformed elastic legs 62 have not fully returned to their original shape, the elastic legs 62 still push the sliding members 6A, 6B towards each other, so the locking rod 5 can be held under the elastic force of the elastic legs 62. is securely held in the locking opening 72 or locking portion 7 .

Because the locking lever 5 is thus locked to the locking portion 7, the clip base 2 and the cover plate 3 maintain an overlapping relationship with each other, so the strap 210 inserted between the clip base 2 and the cover plate 3 is securely clamped. among them. Therefore, the small pocket 100 is securely held to the backpack 200 .

To unlock the pouch 100 from the backpack 200; the user first presses with the thumb and forefinger on the pressing surfaces 67 of the slide members 6A, 6B. When the slide members 6A, 6B are moved close to the unlocked position, the first and second clamping surfaces 71A and 71B are separated and the locking opening 72 is widened enough to allow the locking pawl 52 to pass therebetween. Under such a configuration, the user turns the cover 3 with the remaining fingers to separate it from the clip base 2 , so as to pull the locking claw 52 out of the locking opening 72 . Consequently, the locking lever 5 is disengaged from the locking position 7 .

After the strap 210 is released from between the clip base 2 and the cover 3 , the strap 210 can be released from the holding piece 33 , so the clip 1 can be released from the backpack 200 . In other words, the small pocket 100 can be unfastened from the backpack 200 .

According to the first embodiment of the present invention, the following advantageous effects can be obtained:

(1) Because the sliding members 6A, 6B do not form a part of the clip base 2 or the cover 3, in other words, the sliding members 6A, 6B are separated from the clip base 2 or the cover 3, regardless of the clip base 2 and the cover 3 Whatever material they are made of, no matter what shape they are made of, will not adversely affect the movement of the sliding members 6A, 6B.

(2) With the effect described in (1), no matter what material the clip base 2 is made of, no matter what shape they are made of, the sliding members 6A, 6B can move easily, so the user can use a relatively small Force unhooks or unlocks the cover 3 from the clip base 2. Thus, the clip 1 is easy to handle and the range of use of the clip 1 can be expanded.

(3) With the effect described in (1), when determining the material and shape of the clip base 2 and the cover plate 3, the various uses and strengths of the clip 1 must first be considered, so that a strong and easy-to-handle clip can be realized 1.

(4) In order to lock the locking lever 5 into locking engagement with the locking part 7, two actions must be performed: first, the sliding members 6A and 6B are moved to the unlocked position, and thereafter, the locking lever 5 is inserted into the locking position. Behind the opening 72 , the sliding members 6A and 6B must be moved to the locking position where the locking lever 5 is locked into the locking opening 72 . According to the first embodiment of the present invention, the second movement can be realized automatically by returning the sliding members 6A, 6B to the locked position under the elastic force of the elastic legs 62 . In this way, the user only needs to do the previous action. Moreover, all that has to be done for the previous action is to press the locking lever 5 into the locking opening 72 by fingers, so that the locking operation is very simple.

(5) Once the locking lever 5 is locked to the locking portion 7, due to the elastic force of the elastic legs 62, the sliding members 6A, 6B immediately keep being continuously pushed in the direction that assumes the locked position, so the sliding members 6A, 6B The locked position is never disengaged unless the user deliberately moves the slide members 6A, 6B.

(6) In order to unlock the locking lever 5 from the locking portion 7; first, the user must move the locking members 6A, 6B from the locking position to the unlocking position. However, once moved to the unlocked position, the sliding members 6A, 6B will immediately and automatically recover from the unlocked position to the locked position under the elastic force of the elastic legs 62, so the user does not need to do anything to make the sliding members 6A, 6B move to the locked position. locked position.

(7) Since the elastic legs 62 are integrally formed to the slide members 6A, 6B, the number of parts and the number of steps for assembling the clip are relatively small. Furthermore, the structure of the clip is simple and thus easy to mould.

(8) In order to unlock the locking lever 5 from the locking portion 7, all the user needs to do is to move the locking members 6A, 6B towards each other to bring them to the unlocked position. For this purpose, the user keeps the index finger on the pressing surface 67 of the sliding member 6A, keeps the thumb on the pressing surface 67 of the sliding member 6B, and presses against them with two fingers, whereby the locking lever 5 can be released from the lock. Tight part 7 unlocked. Therefore, the unlocking operation can be performed with only one hand, so such a clip is easy to operate.

(9) Since the holding protrusions 66 formed on the sliding members 6A, 6B are engaged with the holding grooves 245 of the cavities 24, the sliding members 6A, 6B are securely held in the cavities 24, so the sliding members 6A, 6B never Will fall out of the cavity 24 of the clip 1.

(10) Since the retaining groove 245 is formed in the guide wall 244 of the cavity 24, and the slide members 6A, 6B have the retaining protrusions 66 formed on the sides parallel to the notch 65; when the slide members 6A, 6B are inserted into the cavity When in the cavity 24 , the retaining protrusion 66 can deform or deflect inwardly of the sliding members 6A, 6B so that the sliding members 6A, 6B can be easily inserted into the cavity 24 .

The clip 1 according to the first embodiment of the present invention may be structured as shown in FIG. 6 . The locking surface 53 of the locking pawl 52 may be inclined towards the apex 52' of the locking pawl 52 as it approaches the handle 51. The front surface of the engaging protrusion 68A of the sliding member 6A abutting against the locking surface 53 of the locking pawl 52 and the rear surface of the corresponding end of the sliding member 6B may be inclined toward the first and second openings 63A, 63B respectively, respectively. With such a structure, it is difficult for the first and second clamping surfaces 71A, 71B of the shank 51 clamping the lock lever 5 therebetween to move apart from each other. Thus, the locking lever 5 can be locked to the locking opening 72 more reliably.

In the clip 1 according to the first embodiment of the present invention, end openings 241 are formed at both ends of the receiving portion 22 . Alternatively, the clip 1 may have only one opening 241 formed at one end. A slide member 6A is inserted into the cavity 24 through this single opening 241 . The locking surface 53 of the locking claw 52 is engaged with the lower surface of the slide member 6A, so that the clip base 2 and the cover plate 3 are securely connected to each other.

7 and 8 show a second embodiment of the present invention. Fig. 7 is a perspective view of a single slide member 8 according to the second embodiment. FIG. 8 is a perspective view showing the slide member 8 and the cavity 24A into which the slide member 8 is to be inserted.

The orientation of the locking claw 52 of the clip 1A according to the second embodiment, and the structure of the cavity 24A and the locking portion 9 are different from the clip 1 according to the first embodiment.

As shown in FIG. 7 , the sliding member 8 includes a substantially U-shaped profile sliding body 81 and a pair of elastic legs 82A, 82B integrally formed coplanar with the sliding body 81 . The U-shaped profile sliding body 81 includes a rectangular sliding base 81' and a pair of first and second side members 81A and 81B formed one on each side of the sliding base 81' and extending from one end in the same direction. The sliding base 81' and the two side members 81A, 81B define a rectangular notch or cutout 83 between them.

The second side member 81B of the slider 81 has the holding protrusion 66 formed on the outer side thereof. The slide base 81' has a gently curved pressing surface 67 formed at the other end.

The elastic legs 82A, 82B are arranged symmetrically to each other. Each elastic leg 82A, 82B includes a leg support 84 in the form of an elongated plate formed longitudinally inside the side member 81A, 81B and a leg end portion 85 extending longitudinally from the leg support 84 . Each leg support 84 is disposed longitudinally on the inside of the side members 81A, 81B and slopes toward the inside of the side members 81A, 81B in a manner that defines a V-shaped cross-sectional groove between the leg supports 84 and the side members 81A, 81B. . Each leg end portion 85 extends in a curved manner inclined upward from one side member 84 toward the other side member so as to cross the other leg end portion 85 . The leg end portion 85 has a rounded end portion 85' formed at its distal end.

A pair of locking plates 91A, 91B are integrally formed one on the inner side of each leg support 84, adjacent one or upper end thereof. The opposing locking plates 91A, 91B extend toward each other but terminate out of contact with each other, thereby defining a locking opening 92 therebetween. The locking pawl 52 of the locking lever 5 is suitable for locking engagement with the locking opening 92 . The locking plates 91A, 91B and the locking opening 92 together constitute the locking portion 9 .

As shown in FIG. 8, the cavity 24A of the second embodiment differs from the cavity 24 of the first embodiment in that only one end opening 241 is formed at one end thereof. In general terms, the cavity 24A of the second embodiment is shaped like a bag having an opening 241 formed at only one end thereof.

The slide member 8 is inserted into the cavity 24A from one end opening 241, and the holding protrusion 66 is opposed to the holding groove 245 formed in the cavity 24A. At this point, the distal ends of the resilient legs 82A, 82B abut against the bottom 246 of the cavity 24A. Continued entry of the sliding member 8 into the cavity 24A will cause the elastic legs 82A, 82B to be pressed by the bottom surface of the cavity 24A and elastically deformed. The slide member 8 is positively pushed in a direction protruding out of the cavity 24A of the clip base 2 by the elastic force of the elastic legs 82A, 82B thus elastically deformed. The slide member 8 is movable by pressing the pressing surface 67 of the slide member 8 forward or toward the bottom 246 of the cavity 24A.

The method of attaching the small bag to the backpack with the clip 1A according to the second embodiment is the same as the method of attaching the small bag to the backpack with the clip 1A according to the first embodiment in that the locking bar 5 and the locking part 9 The principles of locking engagement and disengagement from each other are different in principle.

First, in order to securely engage the locking lever 5 with the locking portion 9 , the user has to press the cover 3 and the clip base 2 so that the locking claw 52 of the locking lever 5 is kept tightly engaged with the locking opening 92 . At this time, the arcuate ends of the locking claws 52 are pressed against the locking plates 91A, 91B, so the locking plates 91A, 91B and the leg supports 84 on which the locking plates 91A, 91B are supported are elastically deformed or rearward or from The front surface of the clip base 2 is curved in the direction of the rear surface. The rearwardly bent locking plates 91A, 91B allow the locking pawl 52 to be inserted through the locking opening 92 .

Because the shank 51 of the locking rod 5 is narrower than the widest part of the locking claw 52, once the locking claw 52 is fully inserted into the locking opening 9, the deformed locking plates 91A, 91B will be elastic immediately under the action of their elastic force. back so that the rear surfaces of the locking plates 91A, 91B abut the locking surfaces 53 of the locking pawls 52 to hold the locking pawls 52 at the rear surfaces. Thus, the locking lever 5 is locked into the locking opening 92 .

To disengage the locking lever 5 from locking engagement with the locking portion 9, the user presses the pressing surface 67 of the slide member 8 and one side of the clip base 2 with the thumb and forefinger. Thereafter, the slide member 8 continues into the cavity 24A, and the locking plates 91A, 91B are thus moved forward. When the sliding member 8 reaches the unlocked position, the locking plates 91A, 91B are all out of alignment with the locking surface 53 of the locking pawl 52 and the locking surface 53 of the locking pawl 52 is completely separated from the locking plates 91A, 91B.

In this configuration, other fingers are used to separate the cover plate 3 from the clip base 2 , so that the locking claw 52 is pulled out of the locking opening 92 . Consequently, the locking lever 5 is out of locking engagement with the locking portion 7 .

According to the second embodiment, in addition to the effects (1) to (10) obtained from the first embodiment, excluding the effects (4) and (8), the following advantageous effects can be obtained:

(11) The locking claw 52 can be inserted into the locking opening 92 by elastic deformation of the locking plates 91A, 91B and the leg support 84 . Once the locking pawl 52 is inserted into the locking opening 92, the locking plates 91A, 91B elastically return to the locking engagement with the locking pawl 52 immediately under the action of the elastic force of the thus deformed locking plates 91A, 91B and the leg support 84. , so the locking lever 5 is in locking engagement with the locking portion 9 . Thus, in order to bring the locking lever 5 into locking engagement with the locking portion 9 all the user has to do is press the locking lever 5 into the locking opening 92 with his fingers. Therefore, the locking operation is very simple.

(12) The leg supports 84 are inclined with respect to the insides of the side members 81A, 81B in such a manner as to provide a V-shaped cross-sectional groove therebetween, so the locking plates 91A, 91B and the leg supports 84 described above under (11) deformation is easily achieved.

(13) When the sliding member 8 is inserted into the cavity 24A, the retaining protrusion 66 can be easily deformed in the direction of the V-shaped cross-sectional groove, so the insertion of the sliding member 8 into the cavity 24A will be very convenient.

(14) To unlock the locking lever 5 from the locking portion 9 all the user has to do is move the slide member 8 forward or towards the bottom 246 of the cavity 24A until the slide member 8 reaches the unlocked position. Specifically, at first the index finger is kept on the side surface of the clip base 2, the thumb is kept on the pressing surface 7 of the slide member 8, and they are pressed with fingers, so the locking lever 5 can be unlocked from the locking portion 9. Therefore, the user can perform the unlocking operation with only one hand. The unlocking operation is thus easy.

(15) Since only one slide member 8 is used as the slide means, the number of required parts is small. Further, since it is easy to insert a single slide member 8 into the cavity 24A, assembly of the clip 1A is simple and requires little labor.

Conclusions, derived results and scope:

The present invention is not limited only to the above-mentioned embodiments. The present invention may include various modifications, improvements, etc., all of which can achieve the object of the present invention.

According to the present invention, as an option, the locking lever 5 can be arranged on the clip base 2 , and the locking parts 7 , 9 can be arranged on the cover plate 3 .

In the hinge mechanism 4 according to the first embodiment and the second embodiment of the present invention, the hinge pin 42 constitutes a central axis about which rotation takes place. Alternatively, an elastic hinge can be provided at the connecting portion of the clip base 2 and the cover 3 , so that deformation of the elastic hinge produces relative rotation of the clip base 2 and the cover 3 . With such a structure, once the locking lever 5 disengages from the locking engagement with the locking parts 7, 9, the cover plate 3 automatically rotates away from the clip base 2 immediately and automatically by the elastic force of the elastic hinge. Therefore, the user does not need to turn the cover plate 3 .

A pivot with a gear-like notch can be formed on a support 43 provided at the proximal end of the cover and is adapted to engage with the sleeve 41 to adjust the angular position of the cover 3 relative to the clip base 2 so that the cover 3 is fixed at a certain position. Angle.

According to the first and second embodiments of the present invention, the clip base 2 and the cover plate 3 are separated and combined by the hinge mechanism 4 . However, according to the invention, the clip base 2 and the cover plate 3 may be integrally molded with each other.

The first and second embodiments of the present invention use resilient legs 62, 82A, 82B integrally molded on the slide member 6A, 6B or slide member 8 as push means. According to the invention, a separate spring may alternatively be used. If a separate spring is used, the clip 1, 1A can be molded from a strong and almost inelastic metal.

While the above description contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing an introduction to some of the preferred embodiments of this invention.

Accordingly, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.
