[0001]

[Industrial applications]

 The present invention mainly relates to an improvement of a band bag used for connecting a chin strap of a helmet.

[0002]

[Prior art]

 As shown in FIG. 3, a conventional buckle for a band of this type has a band insertion hole 1 formed at one end and an insertion port 2 for inserting a later-described plug 14 at the other end thereof, and is close to the opening of the insertion port 2. A slider 6 made of a single body for releasing the lock that slides against the spring 5 is held in a sleeve 4 in which a locking claw 3 is erected inward at the center, and an operating portion 7 of the slider 6 is held. A socket 10 projecting from a slide hole 9 formed on the surface of the cover part 8 of the above, an insertion piece 12 having a locking hole 11 for locking the locking claw 3, and a band adjusting insertion part 13. And a plug 14 integrally formed with each other, each of which is attached to one end of the band, and the insertion piece 12 of the plug 14 is brought into contact with the tip of the slider 6 exposed at the insertion opening 2 of the socket 10. Slider 6 with When the locking hole 11 of the insertion piece 12 reaches the position of the locking claw 3 in the sleeve 4 by pushing it against the hook 5, the locking hole 11 falls into the locking claw 3 and is locked. At the same time, the slider 6 is returned by the spring 5, and the locking hole 11 and the locking claw 3 are locked. When releasing the lock, contrary to the above-mentioned locking operation, the slider 6 is retracted by operating the operating portion 7 which is projected on the surface of the cover portion 8 and the locking portion of the insertion piece 12 is opened. As a result, the lock is released by removing the locking hole 11 from the locking claw 3 and pulling it out.

[0003]

[Problems to be solved by the device]

 However, with the configuration in which the operating portion 7 of the slider 6 for releasing the lock protrudes from the slide hole 9 formed on the surface of the cover portion 8 of the sleeve 4 as described above, the operating portion 7 is not replaced by the operating portion 7 when falling or the like. There is a problem to be solved such that when an object or the ground comes into contact and an inadvertent operating force is applied, the connection between the socket 10 and the plug 14 is released against the intention.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention forms a band insertion hole 1 at one end and an insertion port 2 for inserting a plug 14 described later at the other end, and locks the insertion port 2 at the center near the opening. In a sleeve 4 in which the claw 3 is erected inward, a slider 6 for releasing a lock that slides against a spring 5 is held, and a socket 10 for sliding operation of the slider 6 is provided. In a buckle for a band, which includes an insertion piece 12 having a locking hole 11 for locking with the locking claw 3 and a plug 14 integrally formed with a band adjusting insertion portion 13, A slide hole 9 is formed in each of them, and the slider 6 is symmetrically divided into two in the sliding direction, and the operation portion 7 is slidably inserted into the slide hole 9 on each outer surface thereof. Made left, right Riders 6a, formed by 6b, characterized in that a configuration which is disposed a spring 5 in each of the rear end.

[0005]

[Action]

 As described above, the slide holes 9 are formed in the both side walls of the sleeve 4, and the slider 6 is symmetrically divided into two in the sliding direction so that the slider 6 can be slid into the slide holes 9 on the outer surfaces thereof. The left and right sliders 6a and 6b are formed with the operating portion 7 to be inserted into the slider, and the springs 5 are provided at the rear ends of the left and right sliders 6a and 6b. The lock cannot be released unless it is operated, and even if an inadvertent force is applied to one of the operating parts 7, only the slider on the operated side operates and the locking claw 3 and the plug 4 are locked. The lock with the hole 11 is not released. Moreover, since no other object, the ground, or the like will contact the left and right operation parts 7 at the same time when falling, it is against the intentional effect of the careless operation force generated by the contact with the operation part 7. The unlocking of the socket 10 and the plug 14 is prevented.

1 is a plan view of a band buckle according to the present invention, FIG. 2 is a side view, and FIG. 3 is a sectional view of a conventional band buckle. The band buckle of the present invention comprises a socket and a plug as in the conventional case, but the socket 10 has a band insertion hole 1 at one end and an engaging claw 3 inwardly at the center near the other end. A concave sleeve main body 16 which is erected upright to hold and fix an inverted concave cover portion 8 to form a stainless sleeve 4 having slide holes 9 formed in both side walls, and the slide sleeve 4 is slid into the sleeve 4. Formed by left and right sliders 6a and 6b, which are symmetrically divided into two parts and formed with an operating portion 7 slidably inserted into the slide hole 9 on the outer surface of each spring. The slider 6 made of Duracon resin in which 5 is arranged is held, and the operating portions 7 of the left and right sliders 6a and 6b are projected from the sliding hole 9 of the sleeve 4, and 14 is the station The insert piece 12 having a locking hole 11 for locking with the locking claw 3 and the band adjusting insertion portion 13 are integrally formed, and particularly the inner surface of the bottom of the sleeve 4 Between the slider 6 and the slider 6, there is fixed a leaf spring 15 which has a free end behind the hook 3 and elastically presses the insertion piece 12 of the plug 14 in the unlocking direction. By doing so, the plug 14 is pushed out, and the center rod 17 of the band adjusting insertion portion 13 bulges into a mountain shape, and the inside of the frame on the side opposite to the insertion piece protrudes to ensure the adjustment and fixing of the band. It is supposed to do. Further, in the above-mentioned structure, the abutting surface 18 formed by chamfering or rounded is provided at the end of the slider 6 with which the tip of the insertion piece 12 of the plug 14 abuts this portion, and the insertion surface of the plug 14 is inserted. In addition, the insertion piece 12 of the plug 14 is pushed down against the leaf spring 15.

The band buckles of the present invention configured as described above are attached to one end of each band in the same manner as in the conventional case, and the insertion piece 12 of the plug 14 is exposed to the insertion opening 2 of the socket 10. The left and right sliders 6a and 6b are pressed against the springs 5 while being in contact with the contact surfaces 17 of the tips of the right sliders 6a and 6b, so that the locking hole 11 of the insertion piece 12 is released. When the position of the inner locking claw 3 is reached, the insertion piece 12 is pushed down against the leaf spring 15 by the guide action of the contact surface 17 to lock the locking hole 11 on the locking claw 3. At this time, the left and right sliders 6a and 6b are returned by the restoring force of the spring 5, so that the locking hole 11 of the insertion piece 12 and the locking claw 3 are locked.

When the lock is released, contrary to the locking operation, the operating portions 7 projecting on both sides of the socket 10 are simultaneously operated with fingertips to move the left and right sliders 6a and 6b into the sliding holes 9 respectively. When the engaging portion of the insert piece 12 is opened, the insert piece 12 of the plug 14 is lifted by the action of the leaf spring 15 and the engaging hole 11 is disengaged from the engaging pawl 3 and the insert piece 12 is retracted. The tip of 12 comes into contact with the tip surfaces of the left and right sliders 6a and 6b, and the plug 14 is ejected by the return of the left and right sliders 6a and 6b by the action of the spring 5. The band buckle of the present invention does not have to be used only for connecting the chin band for helmets, and is highly safe to use for hanging bands such as bags and videos. It goes without saying that you can do it.

[0009]

[Effect of device]

 As described above, in the band buckle of the present invention, the slide holes 9 are formed in both side walls of the sleeve 4, and the slider 6 is symmetrically bisected in the sliding direction, and the slider 6 is formed on each outer surface of the sleeve 6. The left and right sliders 6a and 6b are formed by the left and right sliders 6a and 6b each having an operation portion 7 slidably inserted in the slide hole 9, and the springs 5 are arranged at the rear ends of the left and right sliders 6a and 6b. The lock cannot be unlocked unless both operating parts 7 are operated at the same time, and even if a force in the sliding direction acts on either one of the operating parts 7 inadvertently, only the slider on the operating side operates and The lock between the claw 3 and the hooking hole 11 of the plug 4 is not released. Moreover, since no other object or the ground touches the operation units 7 on the left and right at the same time when falling, it is against the intentional action of the careless operation force generated by the contact with the operation unit 7. It is possible to provide a band buckle which is prevented from unlocking the socket 10 and the plug 14 and prevents the helmet from inadvertently detaching from the head in the event of a fall or the like and has excellent strength and high safety.
