DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a buckle according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations.

FIG. 1 is an exploded perspective view of a buckle 100 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the buckle 100 of FIG.

Referring to these figures, the buckle 100, which is easy to disengage, may have an insertion unit 110, a latching unit 130, and a disengaging unit 150.

The insertion unit 110 is configured to be partially inserted into the latching unit 130 and coupled to the latching unit 130. The insertion unit 110 may have an insertion body 111, an insertion plate 116, and a connection body 121.

The insertion body 111 is configured to define the insertion hollow IS. The insertion body 111 is formed of a generally circular plate, and the insertion hollow IS may also be generally circular. In that case, the insertion body 111 may have a generally donut shape.

The insertion plate 116 is cantilevered to the insertion body 111. Thereby, the insertion plate can be disposed in the insertion hollow portion IS. At this time, the outer peripheral surface of the insertion plate 116 may be composed of a semicircular portion 116a and a straight portion 116b. The rectilinear sections 116b may be provided as a pair extending parallel to each other at both ends of the semicircular section 116a.

The connection body 121 extends from the insertion body 111 and is connected to a strap. To this end, the connecting body 121 may have a connecting rod 123 wrapped by a strap.

The engaging unit 130 is configured to receive a portion of the insertion unit 110 and to be coupled to the insertion unit 110. [ To this end, the latching unit 130 may have a latching body 131, a receiving body 136, and a connecting body 141.

The engaging body 131 is formed to define the engaging hollow portion CS. The engaging hollow portion CS may have a shape substantially corresponding to the insertion plate 116. At this time, the curvature of the inner circumferential surface of the engaging hollow portion CS may be equal to or larger than the curvature of the semicircular portion 116a. Thereby, the insertion plate 116 can be rotated in the engaging hollow portion CS, so that the inserting unit 110 can be relatively rotated with respect to the engaging unit 130. Due to the shape of the engaging hollow portion CS, the engaging body 131 may have a generally donut shape.

The receiving body 136 is configured to form a receiving space AS for receiving the insertion body 111 together with the engaging body 131. [ To this end, the receiving body 136 may be disposed on the lower side of the latching body 131. Thereby, the accommodation space AS can communicate with the engagement hollow portion CS.

The connecting body 141 extends from the engaging body 131 and the receiving body 136 and is connected to a strap. To this end, the connecting body 141 may have a connecting rod 143 wrapped by a strap.

The release unit 150 is a structure for releasing the engagement between the insertion unit 110 and the engagement unit 130. Specifically, the release unit 150 may have a pressure plate 151. The presser plate 151 is a plate member cantilevered to the engaging unit 130 so as to be disposed on the upper side of the insertion plate 116.

The insertion unit 110 described above will be further discussed with reference to FIG.

FIG. 3 is a perspective view of the insertion unit 110 of FIG. 2 viewed from the opposite direction to FIG.

Referring to this figure, the insertion plate 116 may have a horizontal portion 117a, an inclined portion 117b, and a connection portion 117c.

The upper surface of the horizontal portion 117a is a surface that faces the pressure plate 151. [ This upper surface has substantially the same level as the insertion body 111.

The upper surface of the inclined portion 117b is a portion extending upward from the horizontal portion 117a so as to be inclined upward with respect to the horizontal portion 117a. The lower surface of the inclined portion 117b may be substantially flush with the lower surface of the horizontal portion 117a.

The connection portion 117c is a portion to which the insertion plate 116 is connected to the insertion body 111. [ At this time, since both sides of the insertion plate 116 are defined by the pair of rectilinear portions 116b, the connection portion 117c can have a moderately long length.

For this insertion plate 116, a bending line 118 may be additionally formed. The bending line 118 may be a concave line formed in a direction intersecting the pair of rectilinear portions 116b. The bending line 118 may be formed at a portion where the horizontal portion 117a and the inclined portion 117b meet.

According to the above configuration, when the free end side of the insertion plate 116 is pressed, the insertion plate 116 can be strongly supported with respect to the insertion body 111 by the connection portion 117c of a sufficient length.

The insertion plate 116 can be easily pressed downward by the bending line 118, despite the strong support above. When the insertion plate 116 is thus pushed, the insertion plate 116 is easily detached from the engagement hollow portion CS.

Next, the release unit 150 will be described in detail with reference to FIG.

4 is an exploded perspective view of the buckle 100, which is easy to disengage to focus on the release unit 150 of FIG.

Referring to this figure, the releasing unit 150 includes, in addition to the pressing plate 151, the engaging rib 153, the engaging groove 154, the supporting rib 156, the posture maintaining protrusion 157, 158, a hook 161, and a hook groove 162.

The engaging rib 153 is formed so as to protrude from the pressing plate 151. The engaging rib 153 may have a shape protruding continuously along the edge of the end portion of the push plate 151 on one end side.

The engaging groove 154 is configured such that the engaging rib 153 is seated. Specifically, the engaging groove 154 is a groove formed in the receiving body 136 to be concave corresponding to the engaging rib 153.

The supporting ribs 156 are protruded from one side of the engaging groove 154 to support the pressing plate 151. The support ribs 156 can be located in the receiving space AS. In addition, the height of the support ribs 156 may not be equal to the height of the latching unit 130.

The posture maintaining protrusion 157 protrudes from the presser plate 151. [ More specifically, the posture maintaining protrusions 157 may be provided as a pair arranged on the front side of both ends of the engaging rib 153.

The seating groove 158 is a recessed configuration formed in the supporting rib 156 in correspondence with the posture maintaining protrusion 157. [ The seating grooves 158 may be provided on both sides of the support ribs 156, corresponding to the posture maintaining protrusions 157, respectively.

The hook 161 is a projection for engaging with the pushing plate 151. The hook 161 may be located on the end side of the push plate 151 where the engaging rib 153 is formed.

The hook groove 162 is a groove for the hook formed in the receiving body 136 in correspondence with the hook 161.

According to this configuration, in order for the pressure plate 151 to be cantilevered to the receiving body 136, the engaging rib 153 can be inserted into the engaging groove 154 first. At this time, since the posture holding protrusion 157 formed on the presser plate 151 is seated in the receiving groove 158, the presser plate 151 is positioned in the normal posture without swaying from side to side.

In addition, when the hook 161 is engaged with the hook groove 162, the pressure plate 151 can be firmly held so as not to be disengaged from the engaging hollow portion CS. The engagement of the hook 161 with the hook groove 162 is achieved while the engaging rib 153 is inserted into the engaging groove 154.

In such a coupling, an adhesive may be applied between the engaging rib 153 and the engaging groove 154. Alternatively, they may be partially melted using ultrasound to bond them together.

The coupling between the coupling rib 153 and the coupling groove 154 may be combined with the coupling between the hook 161 and the hook groove 162 so that the pressing plate 151 is inserted into the receiving body 151 without using the above- (136). ≪ / RTI >

The operation of the buckle 100, which can be easily disengaged by the above-described structure, will be described with reference to Fig.

5 is a cross-sectional view of the buckle 100 taken along the line (V-V) of FIG.

Referring to the drawings (and Figs. 1-4), the insertion unit 110 can be inserted in the insertion direction I of the latching unit 130 in the insertion direction I. Thereby, the insertion body 111 and the insertion plate 116 are located in the accommodation space AS.

At this time, since the free end of the insertion plate 116 is deflected upward in the drawing, the insertion plate 116 is positioned at the engagement hollow portion CS defined by the engagement unit 130. As a result, even if the insertion unit 110 is pulled in the direction opposite to the insertion direction I with respect to the engagement unit 130, the free end of the insertion plate 116 is engaged with the engagement body 130 defining the engagement hollow CS 131). Thereby, the insertion unit 110 is prevented from being detached from the latching unit 130.

When the user wants to separate the insertion unit 110 from the engagement unit 130, the release unit 150 can be used. Specifically, when the pressing plate 151 of the releasing unit 150 is pressed in the pressing direction F, the insertion plate 116 under the pressing plate 151 is also pressed. Thereby, when the insertion plate 116 is disengaged from the engagement hollow CS, it can be separated from the engagement unit 130 as the insertion unit 110 is pulled in the opposite direction of the insertion direction I.

The presser plate 151 is in a state in which the engaging rib 153 is seated in the engaging groove 154 and the hook 161 is engaged in the hook groove 162 so that the presser plate 151 is firmly engaged with the receiving body 136 . Further, since the pressure plate 151 is supported by the support ribs 156, it is possible to stably perform the cantilever motion against the force applied to the pressure plate 151 in the pressing direction F. [

Next, the buckle 200, which is easy to disengage from the above, will be described with reference to Figs. 6 to 8. Fig. The same reference numerals are assigned to the same or corresponding components of the configuration of the present embodiment, and a detailed description thereof is omitted in the description of the preceding embodiments.

FIG. 6 is an assembled perspective view of a buckle 200 which is easy to disengage according to another embodiment of the present invention.

Referring to this figure, the buckle 200, which is easy to disengage, may have an insertion unit 210, an engagement unit 230, a release unit 250, and a restriction unit 270.

The insertion unit 210, the engagement unit 230, and the release unit 250 are substantially the same as those of the previous embodiment.

The restriction unit 270 is movably installed in the release unit 250 and selectively restricts the pressing operation with respect to the pressure plate 251. [ Specifically, the restriction unit 270 may have a restriction plate 275 slidably coupled to the pressure plate 251.

The restricting plate 275 may have a restriction portion 275a, which may be located at the engagement body 231, as an area at one end side thereof. When the restricting portion 275a is positioned on the engaging body 231, the restricting plate 275 may be said to be in the restricting position. Alternatively, if the restricting portion 275a is separated from the retaining body 231 and positioned on the pushing plate 251, the restricting plate 275 may be said to be in the "pushing permitting position".

According to such a configuration, depending on whether the limiting unit 270 is placed in the push-rest position or in the push-permitting position, the push plate 251 can be pressed or vice versa. This is connected to the release of the engagement between the insertion unit 210 and the engagement unit 230 by the pressure plate 251. [

The specific configuration of the limiting unit 270 described above will be described with reference to FIG.

FIG. 7 is an exploded perspective view showing the release unit 250 and the restriction unit 270 of FIG.

Referring to this figure, the limiting unit 270 may have a rail 271, a slider 273, a stop projection 277, and a stop groove 279 in addition to the limiting plate 275 described above.

The rail 271 may be formed at both edges of the opening 251a formed in the press plate 251. [ The rail 271 is elongated along the moving direction of the limiting plate 275.

The slider 273 is configured to be slidably coupled to the rail 271. The slider 273 may be provided on the bottom surface of the restriction plate 275. The slider 273 may also be formed to be elongated along the moving direction of the restriction plate 275.

The stop projection 277 is cantilevered to the push plate 251. In this embodiment, the stopping projection 277 may be located in the opening 251a.

The stop groove 279 is configured to be recessed to receive the stop projection 277 in the limit plate 275. The stop groove 279 can be provided in two to accommodate the stop projection 277 when the restriction plate 275 is positioned in the push-rest position and the push-in position, respectively.

The operation of the buckle 200, which is easy to disengage by such a construction, will be described with reference to Fig.

8 is a cross-sectional view of the buckle 200 taken along line (VIII-VIII) of FIG.

Referring to this figure, in the buckle 200 which is easy to disengage, the basic operation of the engagement between the insertion unit 210 and the engagement unit 230 and the disengagement unit 250 is the same as in the previous embodiment.

However, the pressure plate 251 of the release unit 250 in this embodiment differs from that of the previous embodiment in that it selectively operates by the restriction unit 270. [

Specifically, when the restricting portion 275a of the restricting plate 275 of the restricting unit 270 is on the retaining body 231, the retaining plate 231 is formed as a lump of the pressure plate 251 and the restricting plate 275, . Thereby, even if the pressing plate 251 or the limiting plate 275 is pressed in the pressing direction F, the pressing plate 251 can not press the insertion plate 216. This prevents the press plate 251 from being released from the engagement between the insertion unit 210 and the engagement unit 230, regardless of the intention of the user.

Alternatively, when the restriction plate 275 is retracted in the slide direction S, the stop projection 277 is received in the stop groove 279 other than the stop groove 279 in this figure. The restricting portion 275a of the restricting plate 275 is separated from the retaining body 231 and is positioned only on the pressure plate 251. [ Thereby, when the limiting plate 275 or the pressing plate 251 is pressed in the pressing direction F, the pressing plate 251 can press the insertion plate 216 without being caught by the engaging body 231. [

The buckle that is easy to disengage as described above is not limited to the configuration and the operation manner of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
