Description

  The present invention relates to a buckle provided with a male member and a female member. In detail, it is related with the buckle used in order to connect and isolate | separate the both ends of one string-like member, or two string-like members.

  In a buckle with a structure in which an opening that exposes the operating portion of the male member is formed on the female member, an end of a belt, tape, or other fabric, or other foreign matter is provided between the periphery of the opening and the operating portion. For example, a buckle (see Patent Document 1) that prevents this has been proposed.

This comprises a male body and a female body into which the male body is plugged and engaged. The male body includes a base, a plug formed to project from the base, a lock formed on the plug, and an operation unit that elastically deforms the plug formed with the lock. Have The female body has a locked portion that engages with the locking portion of the male body and holds the male body in the female body, and an opening that exposes the operating portion of the male body to the outer surface.
When the male body is engaged with the female body, the operating portion of the male body is exposed to the outer surface from the opening of the female body. Therefore, the elastic covering portion that covers the operating portion exposed to the outer surface is the female. It is provided on the outer periphery of the body.

JP-A-8-299030

  In the case of the buckle disclosed in Patent Document 1, in the state where the male body is engaged with the female body, the entire operation section exposed on the outer surface is elastically covered with the covering section, so The elastic force of the covering portion is always applied. That is, since the force which presses an operation part in the direction from which a latching part remove | deviates from a to-be-latched part is added, even if a slight force is applied to a coating | coated part, a latching part tends to remove | deviate from a to-be-latched part.

  The object of the present invention is to solve such a problem and avoid the problem that foreign matter is caught between the periphery of the opening and the operation portion, and the structure in which the engagement between the male member and the female member is not easily released. To provide a buckle.

  The buckle of the present invention includes a male member and a female member into which the male member is inserted and engaged. The male member is provided with a base, a leg projecting from the base, and the leg. And an engaging portion engageable with the female member, the female member including an insertion port into which the leg portion of the male member is inserted, and the leg portion inserted through the insertion port. A portion where at least one of the engaging portion and the engaged portion is formed in at least one of the male member and the female member is elastically deformed. In the buckle provided with an elastic cover member that covers the operation part exposed on the outer surface in a state in which an operation part to be moved is formed and the male member is engaged with the female member. Between the inner surface of the member and the operation unit, there is an operation method of the operation unit. Wherein the gap is formed.

According to this structure, in a state where the male member is engaged with the female member, the operation part exposed on the outer surface is covered with the cover member, and no opening or the like appears on the outer surface of the female member. It is possible to avoid a problem that foreign matter is sandwiched between the peripheral edge of the unit and the operation unit.
In this state, a gap is formed in the operation direction of the operation unit between the inner surface of the cover member and the operation unit, so that the force that presses the operation unit, that is, the engagement of the male member and the female member is covered. Since no force is applied to press the operating portion in a direction in which the engaging portion is disengaged, the structure in which the engagement between the male member and the female member is not easily released can be achieved.
In order to release the engagement between the male member and the female member, the operation portion is pressed through the cover member. At this time, since the cover member is formed of an elastic material, the pressing operation can be easily performed.

In the buckle of the present invention, it is preferable that the operation portion is formed on the female member, and the leg portion of the male member is elastically deformed and moved by the operation portion formed on the female member.
When the operation part is a buckle formed on the male member, when the cover member is pressed, the inner surface of the cover member comes into contact with the operation part and is likely to be in close contact with the male member, making it difficult to pull the male member from the female member. In particular, when the cover member is formed of a material such as rubber, the frictional resistance is large, and the inner surface of the cover member is in close contact with the operation portion, so that the male member is more difficult to pull out from the female member.
According to the present invention, the operation part is formed on the female member, and the leg part of the male member is elastically deformed and moved by the operation part formed on the female member. Even if the inner surface of the member is in contact with or in close contact with the operating portion, the male member can be easily pulled out of the female member because the cover member is not in close contact with the male member. Further, in the case of the structure in which the operation portion is formed on the female member, the operation portion may be spread outward. However, since the operation portion is covered with the cover member as in the present invention, the operation portion may be spread outward. Can be avoided.

In the buckle of the present invention, the cover member is formed in a cylindrical shape, a close contact portion that is in close contact with the outer peripheral surface of the female member is formed at both end portions in the cylindrical direction, and a pressing portion that presses the operation portion is formed in an intermediate portion. Preferably, the gap is formed between the inner surface of the pressing portion and the operation portion.
According to this configuration, the cover member is formed in a cylindrical shape, and the close-contact portions that are in close contact with the outer peripheral surface of the female member are formed at both end portions in the cylindrical direction. . That is, since the cover member is less likely to be displaced in the insertion / reverse insertion direction and the outer circumferential direction of the male member with respect to the female member, it is possible to maintain the state where the pressing portion of the intermediate portion always faces the operation portion. Therefore, it is possible to prevent the cover member from being displaced with respect to the female member and the pressing portion from being displaced from the operation portion during use, so that the engagement between the male member and the female member can be easily released even during use. Can be a structure that is not.

In the buckle of the present invention, the pressing portion is formed in a shape in which the outer surface of the portion facing the operation portion with a gap is bulged outwardly from the one contact portion toward the other contact portion. It is preferable that
According to this configuration, since the outer surface of the portion of the pressing portion that faces the operating portion bulges outwardly, the operating portion can be recognized from the outside of the cover member, and the pressing portion Easy to operate. In other words, if the pressing part is flat or recessed, it must be pressed so that it is further recessed inward, so it is difficult to operate, but as in the present invention, it protrudes outwardly like a convex shape. Easy to operate.

The buckle of this invention WHEREIN: It is preferable that the recessed part in which the said cover member is accommodated is formed in the outer peripheral surface of the said female member.
According to this structure, since the recessed part in which a cover member is accommodated is formed in the outer peripheral surface of a female member, when a cover member is accommodated in a recessed part, a cover member is hold | maintained in a recessed part and a female member Difficult to shift against. Therefore, the structure in which the engagement between the male member and the female member is not easily released during use or the like can be achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
<First Embodiment>
1 is an exploded perspective view showing the buckle 1 of the first embodiment, FIG. 2 is a perspective view showing a female member B and a male member A to which a cover member C is attached, and FIG. FIG. 4 is a sectional view showing a state in which the male member A is engaged with the female member B. FIG.

(overall structure)
As shown in these drawings, the buckle 1 of the present embodiment is for connecting and separating the end portions of the string-like member, and is integrated with the male member A integrally formed with synthetic resin and similarly with synthetic resin. The female member B is formed and the male member A is inserted and engaged therein, and the cover member C is integrally formed of an elastic material and is attached to the outer peripheral surface of the female member B.
In addition, about the material of the male member A and the female member B, other materials, such as not only a synthetic resin but a metal, may be sufficient. Moreover, as a material of the cover member C, silicon rubber, an elastomer, or the like can be suitably used, but the material is not limited to this as long as the material has elasticity.

(Male member A)
The male member A is formed so as to protrude in parallel with each other in the length direction (insertion direction of the male member A) from both sides of the base portion 10 and the width direction of the base portion 10 (direction orthogonal to the insertion direction of the male member A). A pair of guide pieces 15 and directions protruding in parallel to each other in the length direction (insertion direction of the male member A) from the position inside the guide pieces 15 and approaching or separating from each other (inward and outward directions) And a pair of leg portions 20 that are elastically deformable.

The base 10 is constituted by a horizontally long rectangular frame frame 12 having a string attachment hole 11 as a string attachment part into which an end of the string-like member is inserted and locked at the center of the inside.
A connecting rod 13 is installed in the middle of the string attaching hole 11 in the width direction of the frame frame 12, and the connecting rod 13 causes the string attaching hole 11 to be opposite to the front end side in the insertion direction in which the leg portion 20 is provided. It is divided into two string attachment holes 11A, 11B on the rear end side in the insertion direction on the side. Accordingly, the length of the string-like member can be adjusted by inserting the string-like member through the string attachment holes 11A and 11B and turning the string-like member around the connecting rod 13.
The guide pieces 15 protrude in parallel with each other and are formed to have a length of about ½ with respect to the length of the leg portion 20.

The leg portion 20 extends linearly from the middle of the base portion 10 toward the insertion direction of the male member A and is elastically deformable in a direction toward or away from each other, and at the tip of the elastic piece portion 21. It has the guide part 23 and the engaging part 25 which were formed.
In the central portion of the elastic piece portion 21, a groove 22 penetrating the front and back surfaces is continuously formed up to the guide portion. Thereby, the elastic piece part 21 is comprised by the parallel walls 21A and 21B of the both sides which pinched | interposed the groove | channel 22, and can be elastically deformed easily inward and outward.
The guide part 23 has a tip formed in an arc shape, and an outer surface formed on an inclined surface 24 inclined outward from the tip in the counter-insertion direction.
The engaging portion 25 is configured by an engaging surface formed at a substantially right angle from the outer surface of the guide portion 23 toward the inner side.

(Female member B)
The female member B includes a flat cylindrical female member body 40 having a front wall 40A and a back wall 40B that constitute the front and back surfaces, and a pair of side walls 40C that connect them.
An insertion port 41 into which the pair of leg portions 20 of the male member A is inserted is formed at one end of the female member main body 40, and an end portion of the string-like member is inserted into the other end of the female member main body 40. A string attaching hole 43 and a connecting rod 44 are formed as a string attaching portion to be locked.

  A partition wall 45 that connects the front wall 40A and the back wall 40B is integrally formed in the center of the female member main body 40 from the insertion port 41 toward the back of the female member main body 40. Abutting walls 46 are provided on both sides of the wall. The contact wall 46 is formed with a contact guide surface 47 that contacts the guide portion 23 of the male member A on the insertion port side and elastically deforms the legs 20 in a direction approaching each other. An engaged portion 48 with which the engaging portion 25 of the male member A is engaged is formed.

An opening 49 is formed in an intermediate portion of the side wall 40C excluding both ends in the insertion direction, and a portion where the engaging portion 25 of the male member A is formed from the opening 49, that is, the leg portion 20 is elastically deformed inward. The operation unit 50 to be moved is exposed.
The operation unit 50 is integrally formed from the side wall 40C on the insertion port 41 side of the female member main body 40, and is exposed to the operation surface 51 from the opening 49 to the outer surface. And a pressing piece 52 integrally formed at a substantially right angle. The operation piece 51 is formed to be thinnest so that a portion connected to the side wall 40C can be elastically deformed, and is formed to gradually increase in thickness toward the pressing piece 52. The tip of the pressing piece 52 is opposed to the outer surface (inclined surface 24) of the guide portion 23 of the male member A, and when the operating piece 51 is pressed inward, the outer surface (inclined surface) of the guide portion 23 of the male member A. 24), the leg portion 20 is elastically deformed inward. Thereby, the engaging part 25 of the male member A is released from the engaged part 48 of the female member B.

  A concave portion 55 in which the cover member C is accommodated is formed on the outer peripheral surface of the female member main body 40. The recess 55 is a region that covers the opening 49 and the operation unit 50 of the female member main body 40, that is, the front wall 40 </ b> A, the back wall 40 </ b> B, and the side wall 40 </ b> C that form the female member main body 40. In the region excluding the portion (the portion of the string attachment hole 43 and the connecting rod 44), it is formed as a step that is recessed more inward than the other portions. In other words, a protruding edge is formed along the edge of the insertion port 41 of the female member body 40 so that the outer surfaces of the front wall 40A, the back wall 40B, and the side wall 40C protrude outward, and the female member Similarly, the base portion (that is, the belt attaching portion) of the main body 40 protrudes outward, and a recess 55 is formed therebetween. Further, in the side wall 40 </ b> C portion, the opening 49 is formed so as to be recessed further inside than the recess 55.

(Cover member C)
The cover member C covers the operation portion 50 exposed on the outer surface in a state where the male member A is engaged with the female member B, and has a rectangular tube shape that fits into the concave portion 55 of the female member B, that is, the skin 60A
The back skin 60B and the side skin 60C connecting them are formed in a rectangular tube shape. Close contact portions 61 and 62 that are in close contact with the outer peripheral surface of the female member B are formed at both ends of the rectangular tube in the cylindrical direction, and a pressing portion 63 that presses the operation portion 50 is formed at an intermediate portion.
The thickness of the close contact portions 61 and 62 on the opening end side is formed to be substantially equal to the depth of the concave portion 55 of the female member B. Thus, when the cover member C is mounted in the recess 55, the outer surface of the female member B and the outer surface of the cover member C are formed on a surface that is continuous without a step. Among the contact portions 61 and 62, the contact portion 61 on the insertion port side is formed with a substantially uniform thickness from the opening end toward the pressing portion 63, and then the inner surface side of the side skin 60C gradually increases in thickness. It is formed in a cross-sectional shape having a raised portion 64. When the raised portion 64 is fitted into the concave portion of the base portion of the operation portion 50, the cover member C is structured not to be displaced with respect to the insertion direction.
The pressing portion 63 has a shape in which the outer surface of the side skin 60 </ b> C bulges outwardly toward the close contact portion 62 from the close contact portion 61 and has a substantially uniform thickness. Thus, a gap 65 is formed in the operation direction of the operation unit 50 between the inner surface of the pressing unit 63 and the operation unit 50. In addition, on the outer surface of the side skin 60C of the pressing portion 63, three anti-slip ridges 66 are formed at predetermined intervals.

(Action / Effect)
Insert the cover member C while expanding the cover member C while covering the outer side of the female member B, and attach it to the recess 55 of the female member B. Then, the operation part 50 exposed on the outer surface of the female member B is covered with the cover member C, and no opening or the like appears on the outer surface of the female member B. , It is possible to avoid the problem that foreign matter is caught.
In particular, in the case of a type in which the operation unit 50 is provided on the female member B, the operation unit 50 may expand outward. However, since the operation unit 50 is covered with the cover member C as in the present embodiment, the operation unit 50 is provided. There is no risk of spreading outward, and therefore a mechanism for preventing this can be omitted. Therefore, since the structure becomes simple, it can be manufactured at low cost.

  When the pair of leg portions 20 of the male member A are inserted from the insertion ports 41 of the female member B, the guide portions 23 provided at the distal end portions of the respective leg portions 20 come into contact with the contact guide surfaces 47 of the contact walls 46. The tip portions of the pair of leg portions 20 are elastically deformed so as to approach each other. When the engaging portion 25 eventually reaches the engaged portion 48 beyond the abutting wall 46, the engaging portions 25 are separated from each other by the elastic restoring force of the pair of leg portions 20, as shown in FIG. And is engaged with the engaged portion 48 of the female member B.

  In this state, since the gap 65 is formed in the operation direction of the operation unit 50 between the inner surface of the cover member C and the operation unit 50, the force that presses the operation unit 50, that is, the engagement of the male member A Since the force which presses the operation part 50 in the direction from which the part 25 remove | deviates from the to-be-engaged part 48 of the female member B is not added, it can be set as the structure where engagement with the male member A and the female member B is not easily cancelled | released.

To release the engagement between the male member A and the female member B, the pressing portion 63 of the cover member C is pressed and the operation portion 50 is pressed inward. At this time, since the cover member C is formed of a material having elasticity, the pressing operation can be easily performed. In addition, since the protrusion 66 for preventing slip is formed on the outer surface of the pressing portion 63, the pressing operation can be reliably performed.
As shown in FIG. 5, the pressing portion 63 of the cover member C is elastically deformed by the pressing operation of the cover member C, and when the inner surface of the pressing portion 63 contacts the operating portion 50, the operating portion 50 is also pressed inward. When the operation part 50 is pressed inward, the tip of the pressing piece 52 comes into contact with the outer surface of the guide part 23 of the male member A and elastically deforms the leg part 20 inward. Thereby, the engaging part 25 of the male member A is released from the engaged part 48 of the female member B. Therefore, in this state, when the male member A is pulled out from the female member B, the male member A can be removed from the female member B.

By the way, when the operation part is a buckle formed on the male member, if the cover member is pressed, the inner surface of the cover member comes into contact with the operation part and tends to come into close contact with each other, so that it is difficult to pull out the male member from the female member.
In the buckle 1 of the present embodiment, the operation portion 50 is formed on the female member B, the leg portion 20 of the male member A is elastically deformed inward by the operation portion 50 formed on the female member B, and the engagement portion 25 is The cover member C is in close contact with the male member A even if the inner surface of the cover member C comes into contact with and comes into close contact with the operation unit 50 by pressing the cover member C because of the configuration that is released from the engaged portion 48. Therefore, the male member A can be easily pulled out from the female member B.

  According to the buckle 1 provided with such a cover member C, the cover member C is formed in a cylindrical shape, and close contact portions 61 and 62 that are in close contact with the outer peripheral surface of the female member B are formed at both ends in the cylindrical direction. Therefore, the cover member C is not easily displaced with respect to the female member B. That is, since the cover member C is less likely to be displaced from the female member B in the insertion / reverse insertion direction and the outer circumferential direction of the male member A, the intermediate portion pressing portion 63 always faces the operation portion 50. Can be maintained. Accordingly, it is possible to prevent the cover member C from being displaced with respect to the female member B and the pressing portion 63 from being displaced from the operation portion 50 during use, so that the male member A and the female member B can be used in use. The structure can be such that the engagement is not easily released.

  Moreover, in the pressing part 63 of the cover member C, since the outer surface of the part facing the operation part 50 bulges outwardly, the part of the operation part 50 can be recognized from the outside of the cover member C. it can. In addition, since the pressing portion 63 bulges outwardly, it is easy to press the pressing portion 63. For example, if the pressing part is flat or recessed, it is difficult to operate because it has to be pressed so that it is further recessed inward from there, but it is bulging outwardly like this embodiment Easy to operate.

Moreover, since the cover member C covers the area | region except the insertion port vicinity of the female member B and a belt attachment part, the designability of the buckle 1 is improved by adding a design device to the cover member C. Can do.
In addition, since the cover member C is formed of silicon rubber or the like, not only is it difficult to slide and the operability is improved, but also an excellent effect on the colorability can be expected. it can.

  Further, since the recess 55 in which the cover member C is stored is formed on the outer peripheral surface of the female member B, when the cover member C is stored in the recess 55, the cover member C is held in the recess 55. Therefore, it is difficult for the female member B to shift. Accordingly, the structure in which the engagement between the male member A and the female member B is not easily released at the time of use or the like can be achieved.
