Rather, these embodiments are intended to provide a more thorough and complete disclosure of the invention and the scope of the invention.

Please refer to Fig. 1. Fig. 1 is a schematic view showing a first embodiment of a wiper receptacle according to the present invention. As shown in Fig. 1, the wiper adapter 1 (hereinafter referred to as the adapter) can be detachably pivoted to the wiper arm (not shown). The adapter 1 comprises two side portions 10. The two side portions 10 are spaced apart along the longitudinal direction of the adapter 1, and the longitudinal direction is defined in the present embodiment as the X direction as shown in Fig. 1, that is, the direction of the longitudinal axis of the adapter 1. It should be noted that, if not specifically mentioned in the embodiment to be described later, the longitudinal direction is represented by the X direction illustrated in each drawing, and the Y direction perpendicular to the X direction is defined as being perpendicular to the X direction. That is, the Y direction is perpendicular to the longitudinal direction of the adapter 1. An accommodating space 20 is formed between the side portions 10 included in the adapter 1 to accommodate the spring rails 30 (as shown in FIG. 2). Wherein, each side portion 10 projects the lower leg 41 and the upper leg 42 between the two side portions 10, that is, the lower leg 41 and the upper leg 42 on each side portion 10 protrude in the Y direction perpendicular to the X direction. The two side portions 10 of the adapter 1 and the lower leg 41 and the upper leg 42 on the two side faces 10 project face to face. In addition, the lower leg 41 and the upper leg 42 are disposed in a manner of engaging a plurality of recesses 31 of the spring rail 30 (as shown in FIG. 2) through interlaced regions that do not overlap vertically, so that the lower leg 41 and the upper leg 42 are provided. The slidable spring rail 30 (as shown in FIG. 2) is between the lower leg 41 and the upper leg 42 to prevent the spring rail 30 (as shown in FIG. 2) from leaving the accommodating space 20.

Please refer to Figure 2 and Figure 3 for further reference to Figure 1. Fig. 2 is a partial schematic view showing the wiper receptacle and spring rail shown in Fig. 1 before installation. Fig. 3 is a partial schematic view showing the wiper receptacle shown in Fig. 1 attached to the spring rail. In detail, the lower leg 41 and the upper leg 42 are disposed in an interlaced manner, and the upper leg 42 and the lower leg 41 do not overlap each other in the longitudinal direction of the adapter 1, and are perpendicular to the longitudinal direction of the adapter 1. There is also no overlapping area in the Y direction of the direction, but a gap difference, and the gap is set corresponding to the thickness of the spring rail 30, so that the spring rail 30 can be stably and properly engaged through the upper leg 42 and the lower leg 41.

Further, the outer shape of the spring rail 30 corresponds to the upper leg 42 and the lower leg 41 and their staggered arrangement, and a plurality of recesses 31 are provided. The recess 30 is sized to fit the upper leg 42 and the lower leg 41 individually, whereby the spring rail 30 can be firmly engaged between the upper leg 42 and the lower leg 41 to prevent the spring rail 30 from leaving the accommodating space 20. In detail, the root of the upper leg 42 can be engaged with the recess 31 provided in the spring rail 30 to be engaged in the recess 31, that is, the root of the upper leg 42 can be opposite the side of the recess 31 of the spring rail 30. Fit and abut, thereby blocking the possibility of displacement of the spring rail 30 in the longitudinal direction. Moreover, when the spring rail 30 is installed in the accommodating space 20, the upper leg 42 abuts against the upper side of the area around the bottom of the recess 31 of the spring rail 30, and the lower leg 41 abuts against the recess 31 of the spring rail 30. The lower side of the peripheral area of the side portion is thereby prevented from being separated from the accommodating space 20 by the direction in which the spring rail 30 is opened by the opening of the accommodating space 20. In this way, the lower leg 41 and the upper leg 42 can be stably fitted to the recess 31 of the spring rail 30 through the arrangement of the lower leg 41 and the upper leg 42 to prevent the spring rail 30 from leaving the accommodating space 20. Incidentally, the lower leg 41 has a notch 410 penetrating up and down, the upper leg 42 is located directly above the notch 410, and the shape of the upper leg 410 is not larger than the shape of the notch 410, and no movable core structure is required on the mold. The side portion can be manufactured by an injection molding process by means of upper and lower splitting, and thereby, a gap between the lower leg 41 and the upper leg 42 can be formed to accommodate the spring member 30.

Further, in the first embodiment of the present invention, the limit portion 43 is more protruded between the side portions 10 between the two side portions 10. The limiting portion 43 can be embedded in one of the recesses 31 of the spring rail 30, and the two abutting surfaces 430 of the limiting portion 43 perpendicular to the protruding direction of the limiting portion 43 (ie, the longitudinal direction) can abut against the side of the recess 31 Further, the spring rail 30 is further blocked from moving in the longitudinal direction (as shown in FIGS. 4 to 7). The abutment surface 430 can cooperate with the side of the recess 31 of the spring rail 30 that has been mounted in the accommodating space 20, so that the spring rail 30 can be fixed in the longitudinal direction (ie, the X direction) of the adapter 1 (see 6 and 7), the spring rail 30 that has been installed in this way will be less likely to sway or detach in the longitudinal direction of the adapter 1. In other words, when the recess 31 of the spring rail 30 is engaged with the abutment surface 430 of the limiting portion 43 perpendicular to the longitudinal side, the through-the-hole 31 and the abutment surface 430 are mutually engaged in the longitudinal direction of the adapter 1. The spring rail 30 can be fixed in the accommodating space 20 (as shown in FIGS. 4 to 7).

In order to enable the reviewing committee to more clearly understand the present invention, the applicant has also proposed Figs. 4 to 7 in the first embodiment of the present invention.
