Description

  The present invention relates to a hand wiper used for scraping or wiping off water, water droplets, etc. remaining on a car body or window glass of an automobile after washing a car or cleaning a window glass of a house. .

  2. Description of the Related Art Conventionally, various hand wipers have been used to scrape water droplets remaining on a car body after a driver or the like has washed the car. For example, a handy wiper as shown in FIG. 7 has been proposed as such a hand wiper. The handy wiper includes a wiper body 31, a handle portion 32 pivotably connected to the wiper body 31, and a wiping portion 33 attached to the wiper body 31. The pivot angle of the part 32 can be automatically changed, and even if the relative position between the body of the automobile and the person using the hand wiper changes one after another, the pivot angle automatically changes, It is designed to surely remove water droplets and the like.

  More specifically, as shown in FIG. 8, the wiper main body 31 is provided with a pair of parallel projecting pieces 34 projecting from the central portion of the upper edge thereof. (Fig. 8 shows only one parallel projecting piece 34 and the engaging projecting element 35). Of the two parallel protrusions 34, the upper edge of one parallel protrusion 34 is formed in a semicircular arc shape, and an arcuate slit 36 is provided slightly away from the upper edge. Thus, an arched leaf spring portion 37 is formed at the upper end portion of the one parallel projecting piece 34. Further, a locking projection 38 projects from the upper end edge of the one parallel projecting piece 34. On the other hand, the lower end portion of the handle portion 32 is composed of a pair of gradient surface portions 39, and a circular recess 40 is formed at the upper end portions of the both gradient surface portions 39 so as to be pivoted to the engagement protrusions 35 (see FIG. In FIG. 8, only one slope surface 39 and the circular recess 40 are shown. Further, a stepped portion 41 having a concave shape in a circular arc when viewed from the front is formed at the lower end portion of the handle portion 32 and elastically slidably contacts the bow-shaped leaf spring portion 37. When the inclination angle of 32 is 90 °, a locking recess 42 is formed to be locked to the locking protrusion 38 in an outer fitting manner.

When the handle 32 is pivotally connected to the wiper body 31, the handle 32 is pushed down from above the parallel projecting pieces 34 of the wiper body 31 toward the parallel projecting pieces 34. Engagement protrusions 35 of both parallel protrusions 34 are pushed and expanded by both sloped surface portions 39, and both engagement protrusions 35 are fitted into circular recesses 40 of both sloped surface portions 39 by the elastic restoring force of both parallel protrusions 34. I do. Further, in a state where the inclination angle of the handle portion 32 is 90 °, the locking recess 42 of the stepped portion 41 of the handle portion 32 is locked to the locking protrusion 38 of the parallel protruding piece 34, and from this state When the handle portion 32 is swung sideways (to the side where the bow-shaped leaf spring portion 37 is formed), the locking recess 42 and the locking protrusion 38 are unlocked, and then the stepped portion 41 is moved. The arched leaf spring portion 37 is elastically deformed by this pressing, and the locking protrusion 38 is elastically brought into sliding contact with the stepped portion 41 by its elastic restoring force. By swinging 32 to an arbitrary pivot angle, the handle portion 32 can be fixed to the pivot angle (see, for example, Patent Document 1).
Registered Utility Model No. 3006580

  However, in the above-described handy wiper, since the handle portion 32 cannot be swung in a direction orthogonal to the wiper body 31, a person using the hand wiper pulls the handle portion 32 toward the front side to obtain a vehicle body or the like. It is difficult to scrape the water drops on the front side. In addition, a pair of parallel projecting pieces 34 project from the center of the upper edge of the wiper body 31, an engaging projection 35 projects from the inner surface of both parallel projecting pieces 34, and one parallel projecting piece 34. A bow-shaped leaf spring portion 37 is formed on the upper end of the bow-shaped plate, and a locking protrusion 38 is projected from the upper edge of the bow-shaped leaf spring portion 37, while the lower end portion of the handle portion 32 is a pair of gradient surface portions 39. A circular recess 40 is formed at the upper end of the both sloped surface portions 39, a stepped portion 41 is formed at the lower end of the handle portion 32, and a locking recess 42 is formed in the stepped portion 41. The structure is complicated and the manufacturing cost is high. In addition, when storing the wiper body 31 with the handle portion 32 connected to the wiper body 31, a large space is required at the storage location. On the other hand, when the wiper body 31 and the handle portion 32 are separated during storage, separation is required. The handle portion 32 must be pivotally connected to the wiper body 31 each time and each time it is used, and the parallel projecting pieces 34 of the wiper body 31 must be expanded by the both sloped surface portions 39 of the handle portion 32 each time. In other words, the two parallel protrusions 34 of the wiper main body 31, the two engaging protrusions 35, the both sloped surface portions 39 of the handle portion 32, and the circular recess 40 are damaged or damaged at an early stage. Moreover, whenever the pivot angle of the handle portion 32 is changed, the bow-shaped leaf spring portion 37 must be elastically deformed, and the bow-shaped leaf spring portion 37 is damaged or damaged at an early stage.
