The present invention relates to a buckle suitable for a case where members are detachably connected to each other, for example.

As shown in Figs. 11 and 12, the buckle of this kind is engaged with the male members 50 and 60 in the female members 55 and 65 so as not to be pulled out. It releases by the operation | movement which presses the operation parts 51 and 61 exposed to the opening 56 and 66 of 65. FIG. In the engagement structure, in the case of FIG. 11, it has the flat operation part 51 formed in the insertion side of the male member 50, and the engagement step part 52 formed using a part of the operation part 51. FIG. The engagement step 52 is engaged with the corresponding engagement portion 57 of the opening 56 by the insertion operation of the male member 50 with respect to the female member 55. In the case of FIG. 12, the female-shaped operation part 61 formed in the insertion side of the male member 60, and the engaging projection 62 formed using a part of the operation part 61, and the engaging projection 62 are The operation of inserting the male member 60 into the female member 65 engages with the corresponding engaging portion 67 of the opening 66. Fig. 11B is a cross sectional view taken along the line H-H in Fig. 11A.

In addition, when the buckle form is grasped from the viewpoint of the conventional buckling release operation, the opening 56 is formed on the upper surface side of the arm member 55 as shown in Figs. ) Is arranged in the opening 56 to release the engagement by pressing in the direction of the arrow in the drawing (hereinafter referred to as a front release type), and the opening 66 is an arm member 65 as shown in FIG. It is formed on the side of, and the operation unit 61 is disposed in the opening 66 is divided into a type (hereinafter referred to as a side release type) to release the engagement by pressing in the direction of the arrow of the figure in the use state.

The above-described conventional buckle is used in many fields, such as a case belonging to a case, a bag body, etc. as a attachment / detachment means of an opening-closing part. However, in the conventional products, for example, when applied to a waist bag or a western-style garment, the use state of Fig. 11 (a) or Fig. 12 has the following problems. In the front release type shown in Fig. 11, in the disengagement operation, the operation portion 51 is pushed downward from the upper side, but the human body is pressed together so that it is easy to absorb the pressure, so the engagement cannot be released stably. In the side release type of FIG. 12, since the pressing direction of the operation part 61 in the engagement release operation is in the state which follows the extension direction of a human body, it can release | release a engagement stably. However, in the side release type, since the operation portion 61 must be pressed simultaneously on both sides as shown by the arrow in the figure, when the finger is injured or paralyzed, the engagement cannot be released normally. Occurs. In addition, the buckle of this kind is, for example, engaged with the male and female members when not in use, and once engaged with the female and male members, is released and arranged in the use form, and then is engaged again. In the non-use state, when the engagement is released, since the arm and male member are not subjected to tension (human force) in the falling direction, even if the engagement is released once by the operation of pressing the operation portion, Unless the attractive force is applied to the male members in directions falling from each other, the male member is engaged again.

An object of the present invention is to enable the engagement release operation with one finger, or to allow the female and male members to be separated by only a pressing operation for releasing the engagement, for example, At the same time, the number of members and the structure are simplified, and the product value is further improved.

In order to achieve the above object, the present invention, as illustrated in Figs. 1 to 10, the male member 3 is engaged in the female member 2 so as not to fall out, and this engagement is the female member 2 In the buckle to be released by the operation of pressing the operation portion 47 exposed to the opening 21 formed in the opening, the engaging portion 44 to engage / release with the insertion side of the male member 3 together with the operation portion 47. And a stopper means (4) mounted on the female member (2) so as to be swingable and supported in the engaging direction, and on one side of the stopper means (4) or the male member (3). And elastic means (37 or 39) for bending spring operation by pressing the operation portion (47) to accumulate spring power in a direction in which the male member (3) falls out. The elastic means (37) is provided with the operation portion (47). Spring power by pressure in direction of disengagement After accumulating, the engagement is released.

In the above buckle, the connecting operation is performed by inserting the male member 3 into the female member 2 or bringing the female and male members 3 and 2 into close contact with each other to close the insertion side of the male member 3 and the stopper means. The engaging portion 44 of (4) is engaged and connected. In this connection state, when the operation part 47 is pressed, the said elastic means 37 or 39 are elastically bent according to the pressure of the operation part 47, accumulate spring power, and the said engagement is released. When the engagement is released, since the spring power accumulated in the elastic means 37 or 39 acts as a force for the male member 3 to fall out, the male member 3 is engaged by the accumulated spring power. It is moved in the direction of exit from the position. Therefore, in this buckle structure, as the conventional buckle releases the engagement so that it will not be engaged again by itself, it is possible to release the engagement and pull both members 2 and 3 in the falling direction at the same time. No troublesome operation is necessary. In addition, the elastic means 37 or 39 accumulate only when the spring power in the direction in which the male member 3 is pulled out is pressed when the operation unit 47 is pressed, that is, the female and male members 2 and 3 are connected to each other. And since the spring power is not expressed in the disconnected state, there is an advantage that can maintain the designed spring power in the long term.

It is more preferable that the present invention described above is embodied as follows.

First, the arm member 2 has a flat case shape, and has the opening 21 on one side surface 20e of the case shape. In this structure, in the invention of claim 1, there is no problem of convenience in use as stated in the buckle 1 of FIG. 11, and unlike the buckle of FIG. 12, the engagement can be released by one finger. In particular, it is possible to improve the convenience at the time of use, especially for infants, the elderly, people with injured hands or fingers.

Second, the elastic means 37 or 39 is formed through the groove portion 36 or 38 with respect to any one of the opposing portions of the stopper means 4 and the male member 3, and the male member ( It consists of the elastic contact part 37a or 39a which accumulate | stores the said spring power in the direction substantially coinciding with the direction in which 3) falls out. This is because the elastic means 37 or 39 are integrally formed with the stopper means 4 or the male member 3, thereby enabling the present invention to be easily realized, and at the same time, the springs of the elastic contact portions 37a or 39a. It is meaningful that the power can act only as a means for the male member 3 to fall out.

Third, the elastic contact portion 37a or 39a is formed on the plate insertion side of the male member 3, and the elastic contact portion 37a or 39a becomes elastically deformable due to the presence of the groove portion 36 or 38. That is, in the elastic contact part 37a of FIG. 5A, the stepped end surface 37b (refer FIG. 1) is used in the middle of the plate insertion side of the male member 3. As shown in FIG. In the elastic contact portion 39a of FIG. 5D, the insertion end side edge itself on the plate insertion side of the male member 3 is used. In these structures, the elastic abutting portion 37a or 39a is provided on the plate insertion side of the male member 3 to facilitate area securing, and to secure the corresponding abutting portion on the stopper means 4 side that touches it. Make it easy to get the freedom of design.

Fourth, the stopper means 4 has a substantially case shape that can accommodate the insertion side of the male member 3, and the engaging portion 44 formed inside the case shape and the case shape. It has the said operation part 47 formed in one side, and the elastic blade piece 41 which protruded out of the other side of this case shape, In the state which engaged the said male member 3 in the female member 2, The engagement is released along the elastic deformation of the elastic blade piece 41 by the operation of pressing the operation unit 47. This makes it possible to easily secure the part opposite to the male member 3 side, which is necessary when laying the elastic means 37 or 39, to the corresponding edge portion of the case shape, and also as a buckle function. The most important engagement portion 44 is located inside the arm member 2 in a more confined space called the case shape of the stopper means 4, so that the effect of dust and the like that enters the arm member 2 well. It is meaningful to not receive.

Fifth, it is the structure comprised by the stopper member which comprises the male member 3, the female member 2, and the stopper means 4, ie, three members. This is particularly significant in that the stopper means 4 are attached to the arm member 3 by itself without using an attachment member, and this makes it possible to equip each of the above advantages with a minimum number of members.

In the following description, the three members 2, 3, and 4 are made clear with the assembly instructions, and then the main part operation is referred to.

(Female member) Here, it demonstrates mainly using FIG.1, FIG.3, and FIG.4. The arm member 2 is roughly outlined with upper and lower surfaces 20a and 20b, cross sections 20c and 20d in the left and right directions, front and rear sides 20e and 20f, and openings 21 in the side surfaces 20e. ) And has a flat case shape. The opening 21 is continuously formed in the corresponding part of the upper surface 20a and the lower surface 20b in a part of side surface 20e. The part extended to the upper surface 20a side of the opening 21 is set larger than the part extended to the lower surface 20b. In the upper surface 20a, the corresponding edge portion of the opening 21 is formed as a smooth tapered surface 21a. On the lower surface 20b, a string through hole 28 is formed on the end face 20d side as shown in Fig. 4A. Each end surface 20c, 20d becomes the edge part of the opening which leads to the inside 22. As shown in FIG.

As shown in FIG. 4, the inside 22 has guide grooves 25, 26 and shaft holes 27 formed in the shielding wall 23 and the reinforcing ribs 24, and on opposite inner surfaces of the upper and lower surfaces 20a, 20b, respectively. ) Among these, the shielding wall 23 is formed in the state joined to the corresponding location, ie, upper and lower surfaces 20a and 20b and corresponding side surfaces 20e and 20f, located on the end face 20d side. Each of the shielding walls 23 is slightly open in space, and the gap between them is so that the corresponding outer side and the inner side 22 communicate with each other. The reinforcing ribs 24 protrude to the outside of each shielding wall 23, and are designed to have reinforcement as well as a function of providing a unique appearance as shown in Figs. 4 (a) and 3 (d). On the other hand, the guide groove 25 is used when assembling the stopper member 4 to be described later. The guide groove 25 is formed in approximately the middle left and right directions of the opposing inner surfaces of the upper and lower surfaces 20a and 20b, as shown in Fig. 4B. It extends to the shaft hole 27 strictly in front of the cross section 20c immediately corresponding to the shielding wall 23. The guide groove 26 guides the slide of the male member 3, which will be described later. The guide groove 26 is located on one side of the guide groove 25 and is a groove slightly deeper than the guide groove 25. It extends to about one third of the interior 22. The shaft hole 27 is a hole for holding the stopper member 4, and the inner surface side of the upper surface 20a is formed in a concave shape 27a, and the lower surface 20b side is a through hole 27b. It is formed.

(Male member) Here, it demonstrates mainly using FIG.1 and FIG.5. The male member 3 has an overall flat plate shape, an outer plate portion 30 which cannot be inserted into the interior 22 of the female member 2, and an insertion plate portion 31 which enters into the interior 22. Is made of. Among these, the outer plate part 30 is formed so that this outer periphery may be substantially continuous with the outer peripheral surface of the arm member 2 in the state in which the insertion plate part 31 was inserted in the arm member 2. Moreover, inside the outer plate part 30, as shown in FIG.5 (c) and FIG.8, the string 5 etc. can be bypassed and attached. As the structure, in this case, the through hole 30a is formed in the thickness portion of the outer plate portion 30 from the outer end face to the inside and communicates with the lower side out there, and the through hole 30a A stopper part 30b is attached to a part of the. However, this itself can be changed as appropriate.

The insertion plate part 31 consists of the insertion base 32 connected to the outer plate part 30, and the insertion front end part 33 located in the front side of the insertion base 32. As shown in FIG. The insertion base 32 is connected to the outer plate portion 30 and is formed slightly thinner than the outer plate portion 30, and has a slide protrusion 32a and an elastic means 37. The insertion end portion 33 forms a plate thickness slightly thinner than the insertion base 32, and a portion 34 having a thinner plate width toward the end, and an engaging portion 35 formed at the tip of the portion 34. Has)

First, in the insertion front end part 33, the part 34 is formed narrow in width as it goes to the front end side. This is a compact case of the stopper member 4, which this portion 34 will be described later. This insertability is taken into consideration because it is inserted inward. The engaging portion 35 is formed as a hook protrusion intersecting with the longitudinal direction of the male member 3.

In the insertion base 32, the slide projection 32a is formed in the position corresponding to the guide groove 26 mentioned above so that it can fit with this groove 26, and the male member 3 is a female member ( It acts to slide well along the guide groove 26 when inserted into the inside 22 of 2) or taken out. On the other hand, the elastic means 37 is provided in the substantially intermediate position of the plate | board width of the insertion base 32, and is implement | achieved by the elastic contact part 37a partitioned between the groove parts 36. As shown in FIG. That is, this elastic contact part 37a is located in the leading edge of the insertion base 32, the groove part 36a formed in the insertion base 32 side, and the insertion tip part 33 side which became one step lower. It is located between the groove part 36b formed in the boundary part of the. Each groove portion 36a, 36b penetrates up and down the plate, and the groove portion 36a side of the rear side (outer plate portion 30 side of the male member 3) is larger than the groove portion 36b on the insertion tip portion 33 side. The groove width is rather large. Then, the elastic contact portion 37a is press-fitted to the stepped end surface 37b (see FIG. 1) of the elastic contact portion 37a while the stopper member 4 described later is engaged with the release member. Spring power can be accumulated by bending toward the side of the groove portion 36a in the direction in which.

(Modification) The male member 3 of FIG. 5D is an example in which the configuration of the elastic means 37 of the male member 3 is modified. Therefore, in the following description, the same code | symbol is attached | subjected to the same site | part as the said modification, and only a change point is stated. The deformed elastic means 39 is laid along one side edge portion of the insertion tip 33 formed one step lower than the insertion base 32 (which has a thin plate thickness), and penetrates the outer side and the groove 38 (up and down the plate). This is realized by the elastic contact portion 39a partitioned between the groove 38. That is, this elastic contact part 39a has the groove part 38 in the insertion base 32 side in the edge part on the opposite side to the side which forms the engagement part 35 among the insertion front end parts 33. As shown in FIG. By being formed in a state inclined toward the front middle of the plate at a partially inserted position, the stopper member 4 described later is pressed against the outer surface 39b of the elastically engaging portion 39a during the disengagement process. The spring power can be accumulated by bending toward the groove portion 38 in the direction in which 3) is released.

Each of the elastic means 37 and 39 or the elastic abutment portions 37a and 39a described above has at least one groove 36 or 38 with respect to any one side of the opposing portion between the stopper means 4 and the male member 3. And the like, to accumulate spring power in a direction substantially coincident with the direction in which the male member 3 is pulled out in the disengagement process of the stopper member 4, and the like. It may be other than this.

(Stopper means) Here, the description will be mainly given with reference to FIGS. 1 and 6. The stopper member 4 forms a substantially flat small case shape that can accommodate the insertion side of the male member 3, and is formed by using the engaging portion 44 formed inside and one side of the small case shape. The operation part 47 and the elastic wing piece 41 which protruded on the outer surface of the case on the opposite side to the operation part 47 are integrally provided, and the whole is rotatably assembled in the inside 22 of the arm member 2. In addition, the outer contour is formed by the upper and lower surfaces 40a and 40b of the small case shape portion, the end surfaces 40e and 40d in the left and right directions, and the front and rear side surfaces 40e and 40f, respectively. It has the form which has the elastic blade piece 41 which protruded in 40f, and the axial part 46 which protruded in the upper and lower surfaces 40a and 40b. In addition, the stopper member 4 is disposed to face the elastic contacting portion 37a of the male member 3, and is engaged to express the spring power by pressing the elastic contacting portion 37a during the disengagement process. It has a contact 48. As shown in Fig. 6 (b), the contact portion 48 is formed at the acute angle with a portion near the top left of the figure in the shape of the end face 40c of the small case shape.

That is, the partition wall 43 and the engaging part 44 are provided in the inside 42 of the small case shape part. The partition wall 43 is coupled to the upper and lower surfaces 40a and 40b as shown in Figs. 1 and 6d and extends in the left and right directions. In the interior 42, the insertion tip 33 of the male member 3 can be inserted into the space between the partition wall 43 and the side surface 40f (see Fig. 9). The engaging portion 44 is to be the counterpart side which engages with the engaging portion 35 so as to be able to engage / release. The engaging portion 44 is coupled to the upper and lower surfaces 40a and 40b and is located near the inner side of the side surface 40f, and is formed as a hook-like protrusion facing the side surface 40e opposite from the side of the side surface 40f. have.

Here, the elastic blade piece 41 becomes a thin plate part, and in the side surface 40f, the base end is inclined so that the base end may be located in the axial part 46 side, and the front end will fall gradually from the side surface 40f. The functional function is to absorb the rattling by pushing the stopper member 4 to one side in a state assembled to the arm member 2 (see FIG. 9), and the engaging portion 35 of the male member 3 is It protects the state engaged with the engagement part 44, and also permits this engagement or disengagement by elastic displacement in this engagement or release engagement process. The shaft portion 46 protrudes from the upper and lower surfaces 40a and 40b so as to fit in the shaft holes 27 (27a and 27b) described above, and is located near the base of the elastic blade piece 41 on the side surface 40f. Located in As for the detail of the shaft part 46, a part of the cylinder part 46a is formed as the notch part 46b like FIG. The configuration of the shaft is such that when the stopper means 4 is inserted from the end face 20c side with respect to the arm member 2, the shaft portion 46 is pushed along the corresponding guide groove 25 described above and the shaft hole 27 ), That is, for ease of assembly. In this way, the stopper member 4 is assembled so as to be swingable by fitting the shaft portion 46 and the shaft hole 27 with respect to the interior 22 of the arm member 2. The operation part 47 is a part which is exposed and arrange | positioned at the opening 21 of the arm member 2 when the stopper member 4 is assembled in the inside 22 in this way. Moreover, on the outer surface of the operation part 47, the some small rib 47a is formed in the outer surface exposed from this opening 21. As shown in FIG. The small rib 47a is effectively designed not only to improve the pressing operability of the operation unit 47 but also to contribute to the novelty of the appearance. Reference numeral 45 is a rotational or swinging restricting portion that abuts on the corresponding portion of the blocking wall 23 in the state of FIG. 9 (c) described later.

(Modification) The stopper member 4 of the modification shown in Fig. 6 (d) is used in pairs with the male member 3 of the modification shown in Fig. 5 (d). Also in this description, the same code | symbol is attached | subjected to the same site | part as the said modification, and only a change point is stated.

The stopper member 4 of FIG. 6 (d) differs in that the portion 49 corresponding to the abutting portion 48 of FIG. 6 (b) has a rounded shape. In the case of the modification, the side surface 40e which forms the small case-shaped part as shown in FIG. 10 is arrange | positioned facing the elastic contact part 39a of the male member 3, and it is the said process in the engagement release process. This is because the elastic contacting portion 39a can be pressed by the swinging end side of the side surface 40e to express the spring power in the portion 39a.

(Other related members) The buckle 1 above is used for various uses or fields like the conventional buckle. 7 and 8 show an example of the attachment configuration for attaching the end 5a of the string 5 to the buckle counterpart, that is, the female member 2 and the male member 3, when actually used. Here, the string 5 is a wide range including a belt, a belt, and the like. The string 5 and the end 5a are denoted by the same reference numerals on the left and right sides of the drawing, and are shown as if they are continuous strings or both ends 5a of the strings. However, this is typical for convenience only, and the shape in which the left and right strings 5 are composed of the same string (in this case, the ends 5a become both ends of the string) and the left and right strings 5 are different from each other. It is only shown, including the shape comprised as a string (in this case, one end of each string is fixed and the free end of each string becomes the corresponding edge part 5a on drawing).

In Fig. 8, the attachment structure of the end 5a of the string 5 to the arm member 3 is common. In this case, the corresponding end 5a is penetrated through the through hole 28 of the lower surface 20b, and the portion 29b in the figure is bypassed so as to surround the inside, so that the bypassed portion is sewn. It superposed | polymerized in the said string part by (6). In each figure of FIG. 8, the attachment structure of the edge part 5a with respect to the male member 3 differs, respectively. That is, the corresponding end 5a of FIG. 8 (a) is guided above the stopper 30b from the lower opening in the passage hole 30a, and then the stopper 30b and the figure of FIG. It enters in the space | interval between the parts 29a, and is led to the lower side of this part 29, and the derived part is superposed | polymerized on the said string part by sewing 6. The corresponding end 5a of FIG. 8 (b) is led down from the front opening in the passage hole 30a from the front opening 30b, and then of the locking portion 30b and the figure. The part 29a is drawn out as it is to wrap inside, and the derived part is polymerized to the string part by sewing 6. Corresponding end 5a of FIG. 8 (c) is led down from the front opening in the passage hole 30a from the front opening 30b, and then of the locking portion 30b and the figure. It enters into the clearance gap formed with the part 29a, and it leads out again from the front opening of the passage hole 30a, and the derived part is polymerized to the said string part by sewing. As described above, various forms with strings are realized in this embodiment, and there is also an advantage that can be selected according to the use. In addition, each sewing 6 is only an example of a joining means, and it does not interfere with other fixing means, such as welding, adhesion | attachment, or cutter fastening.

(Main operation) Next, the engagement / release operation of the above buckle 1 will be described with reference to FIGS. 9 and 10. FIG. 10: corresponds to FIG. 9 about the modification of the male member 3 and the stopper member 4 mentioned above. Therefore, this description mainly explains the case of FIG.

In the above buckle 1, first, in the connecting operation of the female member 2 and the male member 3, the male member 3 is inserted into the female member 2 or the female and male members 2, 3 are inserted. Close contact with each other. Then, the engaging portion 35 enters into the interior 42 (see FIG. 6) of the stopper member 4 so that the engaging portion 44 opposes the elastic deformation of the elastic blade piece 41. Therefore, it rides over and is engaged with this engagement part 44. FIG. Fig. 9A shows the engagement connection state. In this state, the above elastic contact portion 37a is in a non-contact state (or may be in light contact) with the opposing contact portion 48, and the spring power thereof is not yet expressed. This is because, in the above modification, as shown in Fig. 10A, the elastic contact portion 39a of the elastic means 39 is in non-contact state with the side surface 40e of the stopper member 4, whereby spring power is expressed. It is replaced by something that is not.

When disconnecting the female member 2 and the male member 3, the operation part 47 exposed to the opening 21 is pressed by a finger or the like to operate. Then, the stopper member 4 swings or rotates in the pressing direction along the elastic blade piece 41 with the pivot 46 as a point. In this rotation process, since the contact portion 48 presses the elastic contact portion 37a as shown in FIG. 9 (b), the elastic contact portion 37a is pushed into the groove of the groove portion 36a. Gradually spring power is increased. In the modified example, as shown in Fig. 10B, the counterpart of the side surface 40a pushes the elastic abutting portion 39a so that the elastic abutting portion 39a is pushed into the groove of the groove 38. It is replaced by increased power.

The spring power is maximized in the state just before the engaging portion 35 is disengaged from the engaging portion 44, that is, the angle (b) in FIGS. 9 and 10. Therefore, when this engagement is released, the male member 3 is pushed in the drawing direction by the accumulated spring power of the elastic contact portion 37a (FIG. 10 elastic contact portion 39a of FIG. 10). Therefore, it moves by the predetermined distance as shown in (c) of each figure from the engagement position. The movement of the male member 3 is such that the spring power of the elastic abutting portions 37a and 9a acts only in the direction in which the male member 3 is pulled out. 26) smooth operation by being moved while being guided to. Therefore, in the above engagement / release mechanism, it is possible to eliminate the troublesome operation of releasing the engagement and pulling both members 2 and 3 in the falling direction as in the conventional article mentioned in the problem. Since the spring power accumulates only when the contact portions 37a and 9a press and operate the operation portion 47, the initial elasticity (spring power) of the portion can be maintained for a long time. Compared with the side release type, the user can obtain the advantages such as being able to release by one finger or part of the hand.

As described above, according to the buckle of the present invention, in particular, the spring power accumulated in the elastic means at the time of disengagement acts as a power for the male member to be released, and the male member is engaged by the accumulated spring power. It is moved in the direction of exit from the position. Therefore, the present invention, unlike the prior art, can eliminate the possibility that the female and male members will be re-engaged only by pressing the operation unit even when the female and male members are not subjected to the attraction force in the direction in which the female and male members fall. Since the spring power in the direction in which the male member is pulled out does not accumulate only after the operation of pressing the operation unit, it has the advantage that the life of the spring can be kept long, and the number of members can be simplified, too. Product value and reliability can be improved by improving.
