A spacer for a windshield wiper includes an anchoring member, a cylindrical shaft, a biasing device, a bracing stand, and a retaining device. The anchoring member is to be mounted on the wiper blade seat and has a shaft accommodation hole. The shaft is inserted into the hole and is rotatable relative thereto but is not movable in an axial direction. The shaft includes an enlarged head exposed outwardly of the hole and is formed with a radially and outwardly projecting pivot pin that extends into a bearing hole in the bracing stand, thereby mounting the bracing stand on the shaft. The biasing device is sleeved on the shaft to bias the latter to rotate in a clockwise direction. The retaining device retains the bracing stand against rotation by the biasing device once the lower portion of the bracing stand is moved toward the windshield wiper to abut against the windshield so as to space the windshield wiper from the windshield against the urging action of the wiper arm.
A spacer used for positioning a windshield wiper so as to space the windshield wiper from a windshield when the windshield wiper is not in use, the windshield wiper being mounted and urged by a wiper arm to abut against the windshield for wiping rain water therefrom, and including a wiper blade seat mounted pivotally on the wiper arm, and an elongated wiper blade disposed on and attached to the wiper blade seat, the wiper blade including an elongated wiper blade rubber element to abut against the windshield, the spacer being characterized by:

1. Field of the Invention
The invention relates to a spacer, more particularly to a spacer which is adapted to be mounted on a windshield wiper so as to position and space apart the windshield wiper from a windshield of a car when the windshield wiper is not in use.
2. Description of the Related Art
Other features and advantages of this invention will become apparent in the following detailed description of the preferred embodiments of this invention, with reference to the accompanying drawings, in which:
FIG. 1 is a perspective view of a windshield wiper provided with a spacer of this invention;
FIG. 2 is an exploded view of the spacer of this invention shown together with a wiper blade seat of the windshield wiper;
Referring to FIGS. 1 and 2, a spacer 5 of this invention is be fixed on a windshield wiper 1A of a car so as to position and space the windshield wiper 1A from a windshield (not shown) when the former is not in use. The windshield wiper 1A is urged by a wiper arm (not shown) to abut against the windshield for wiping rain water therefrom, and includes a wiper blade seat 1 mounted pivotally on the wiper arm, and an elongated wiper blade 4 disposed on and attached to the wiper blade seat 1 by means of two sets of minor clamps 2 and 3. The wiper blade 4 is formed with an elongated wiper blade rubber element 4A that abuts against the windshield (not shown).
As best illustrated in FIG. 2, the spacer 5 includes an anchoring member 51, a cylindrical shaft 52, a biasing device 53, a bracing stand 54, and a retaining device 514. The anchoring member 51 is integrally formed with the wiper blade seat 1 and includes a shaft accommodation hole 511 which substantially extends toward the wiper blade seat 1 and which is generally parallel to the windshield (not shown). The shaft accommodation hole 511 includes an outer larger portion 511A and an inner narrower tubular end portion 512 so as to define a shoulder 516 therebetween.
The cylindrical shaft 52 includes an enlarged head portion 523 and a distal end portion 521 which is opposite to the enlarged head portion 523 and which has a diameter slightly larger than that of the tubular end portion 512, and an axially extending split 522 formed therethrough so that the end portion 521 can be compressed during insertion so as to snugly engage the tubular end portion 512. The head portion 523 of the shaft 52 has a radially and outwardly projecting pivot pin 525 and an axially extending split 524 formed therethrough to divide the pin into first and second pivot pin portions extending radially outwardly from the shaft axis. The pivot pin 525 is transverse to the shaft 52 and extends in a direction substantially parallel to the windshield wiper 1A.
