no. 1 Embodiment approach ＞

[0047] refer to Figure 1 to Figure 11 The first embodiment will be described. figure 1It is a schematic perspective view of the buckle, which three-dimensionally shows a state in which a male member and a female member of the buckle are connected to each other. In addition, a belt length adjuster is assembled to the male member of the buckle. figure 2 is a schematic exploded perspective view of the male member of the buckle, showing the main body of the male member of the buckle and the pivot member separately. image 3 It is a schematic exploded perspective view of the buckle, which three-dimensionally shows the male member in a state where the main body and the pivot member are separated from each other, and also three-dimensionally shows the female member. Figure 4 is a schematic exploded plan view of the buckle, showing a state where the male member and the female member are separated. Figure 5 is a schematic cross-sectional schematic diagram of a buckle, showing a...

no. 2 Embodiment approach ＞

[0085] refer to Figure 12 and Figure 13 The second embodiment will be described. Figure 12 and Figure 13 It is a schematic partial enlarged view of the buckle, showing the belt locking portion on the free end side of the pivot member when viewed from above. In this embodiment, the concrete shape of the 1st protrusion part 120 and the 2nd protrusion part 220 differs from 1st Embodiment. Also in this case, the same effect as that of the first embodiment can be obtained.

[0086] Such as Figure 12 As shown, the first opposing surface 121 of the first protruding portion 120 and the second opposing surface 221 of the second protruding portion 220 each have a complementary single arc shape. It can be considered that when the pivot member 200 is laid down on the main body 100 , there is a substantially constant space between the first protrusion 120 and the second protrusion 220 along the left-right direction.

[0087] Such as Figure 13 As shown, on the first opposing su...

no. 3 Embodiment approach ＞

[0090] refer to Figure 14 The third embodiment will be described. Figure 14 It is a schematic partial enlarged cross-sectional schematic diagram of a buckle. In this embodiment, unlike the first embodiment, the upper tape winding portion 210 is omitted. Also in this case, the same effects as those of the above-described embodiment can be obtained.

[0091] Such as Figure 14 As shown, the belt winding portion 310 is a rod portion that is bridged on the main body 100 , and does not include a rod portion on the side of the pivot member 200 .

Abstract

The invention provides a belt length adjusting piece which is provided with a belt clamping portion which possesses more powerful belt clamping force. A belt length adjusting piece (300) comprises a main body (100) and a pivoting component (200) which is supported by the main body (100) and capable of pivoting on the main body (100). The belt length adjusting piece is provided with a belt clamping portion (320); when the pivoting component (200) falls on the main body (100), the belt clamping portion (320) can utilize the first projection part (120) of the main body (100) and the second projection part (220) of the pivoting component (200) to clamp and fix a belt. In a pivoting process of the pivoting component (200) in order to fall on the main body (100), the second projection part (220) of the pivoting component (200) moves from top to bottom on the side of the first projection part (120) of the main body (100); when the pivoting component (200) falls on the main body (100), the second projection part (220) is under the first projection part (120), and is vertically separated from the first projection part (120).

Description

technical field [0001] The present disclosure relates to a belt length adjuster. Background technique [0002] Patent Document 1 discloses a structure in which a hinge portion 30 is rotatably supported on a plug 10 . like the literature Figure 7 As disclosed, the strip 3 is wound on the rod-shaped portion 39 . Patent Document 1 also discloses that the strap 3 is held by the clamping portion 37 when the hinge portion 30 is laid down on the plug 10 . The following content is described: the clamping portion 37 includes clamping edges 39A, 18A, and when the hinge portion 30 is in an open state, there is a space between the two clamping edges 39A, 18A, and when the hinge portion 30 is in a closed state, the two clamping edges The two clamping edges 39A, 18A are in contact with each other or approach at very small intervals, capable of clamping the belt 3 (cf. paragraph 0026 of this document). [0003] Patent Document 2 discloses a detachable connector that can easily adjust t...
