Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below based on examples shown in the drawings.

[0025] Figure 1 to Figure 7 shows a detachable bottom stop device with an anti-separation mechanism to prevent detachment in a horizontal direction with respect to the front and rear of the zipper, Figure 8 to Figure 12 Shown is a detachable bottom stop assembly with an anti-disengagement mechanism to prevent disengagement in a direction perpendicular to the front and rear of the zipper.

[0026] First, introduce Figure 1-Figure 7 Detachable bottom stop assembly with detachment prevention mechanism shown. This anti-separation mechanism is provided on a separable bottom stop device 1 having a docking assembly 10 and a locking assembly 20 . When the docking assembly 10 is pulled toward the locking assembly 20 and docked with it, and then rotated to a position where the slider can be pulled upwards, this anti-separation mechanism can prevent the docking a...

Abstract

The present invention provides a separable bottom stop assembly which can be easily operated by children or people who are handicapped with one of their hands. A coupling member and a locking member respectively provided at lower ends of left and right fastener. Then, by pulling down a slider, a lower end portion of the slider urges a pivotal abutting portion of the coupling member to pivotally move a lateral-inserting fitting portion of the coupling member to a position where the slider can be pulled up. A locking projecting portion of the coupling member climbs over a projecting portion of the locking member to be locked so as to prevent separation of the coupling member in a horizontal direction.

Description

technical field [0001] The present invention relates to a detachable bottom stop device of a zipper, and more particularly, to a detachable bottom stop device of the transverse insertion type, which can be easily operated and can prevent the docking assembly and the locking assembly from being operated separated and disconnected from each other. Background technique [0002] A conventional transversal type detachable bottom stop device has been disclosed in US Patent No. 4,139,927. This detachable bottom stopper device includes a docking part and a locking part, which are respectively fixed at the bottom ends of the left and right slide fasteners. In this device, the docking part and the locking part are rotatably docked by means of a pin at their bottom ends. An upper portion of the mating part is turned towards the locking part, a mating part on an inner side of the mating part is inserted into a side groove of the slider, which stops and abuts against a slider of the lo...
