JP3040110U - Arm slide wiper - Google Patents

Abstract

(57) [Summary] [Problem] The present invention aims to secure the entire field of view by eliminating the unwiped corners by sliding the wiper along the side of the glass to make the wiping surface rectangular. This enables wiping of a curved glass having a large curvature such as a cylindrical shape or a conical shape. According to the present invention, a wiper blade and a wiper arm are attached to a cam follower that reciprocates on a traverse cam. As a method of sliding the wiper, a linear motor can be used in addition to the traverse cam.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an arm-sliding wiper used for a window of a vehicle or a vehicle such as a car or a train.

[0002]

[Prior art]

 The origin of the wiper used in transportation such as automobiles and trains is based on the reciprocating movement of the wiper arm centered on the rotation axis of the rotating power, and the wiper arm is fan-shaped at a fixed angle around the rotation axis. Is wiped with a wiper blade that moves reciprocally in a curved manner and is connected to the wiper arm, or is wiped with a wiper blade that moves in a curved line along the circumference of the curved movement of the arm. .

[0003]

[Issues to be solved by the invention]

 The conventional wiper has a curved wiping due to the rotational movement, and therefore there is a problem in safety due to the unwiping remaining at the corners. In addition, there was a problem that it was not possible to wipe a curved glass having a large curvature such as a cylinder or a cone. The present invention has been made in view of the above problems, and its purpose is to make a wiping surface rectangular and to wipe completely four corners. Further, it enables wiping of a curved glass having a large curvature such as a cylindrical shape or a conical shape which cannot be wiped with a conventional wiper.

[0004]

[Means for Solving the Problems]

 The gist is that the traverse cam (3), which is connected to the rotary drive source (1) and has a spiral or inverted spiral groove (2) formed on the longitudinal surface, wipes the glass (4). A wiper arm (7) fixed to a wiper blade (6) is attached to a cam follower (5) which is laid in the take-up direction and meshes with the cam groove (2) of the traverse cam (3). It is an arm slide type wiper characterized by the above.

Further, the present invention lays the secondary side conductor line (9) of the linear motor in the direction of wiping the glass (4), and travels on the secondary side conductor line (9). An arm slide wiper characterized in that a wiper arm (7) having a wiper blade (6) fixed thereto is attached to a conductor (10).

[Example of the invention]

 That is, the present invention is a combination of a traverse cam or linear motor and a wiper blade and a wiper arm of the conventional wipers used in a communication facility such as an automobile or a train, and the basic movement of the wiper arm is the conventional one. Rotating motion of the fan changes from a fan-shaped curved motion around the axis to a linear motion along the side of the glass surface to be wiped, and the wiper arm is slid parallel to the wiping direction to form a rectangular wiping surface. The arm slide type wiper which secures is provided.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of claim 1 of the present invention. In FIG. 1, 3 is a traverse cam. The traverse cam 3 is connected to the rotary drive source 1 on one side, and has a spiral or inverted spiral cam groove 2 engraved on the surface in the longitudinal direction. The traverse cam 3 is wiped along the side of the glass 4. It is laid in the take direction. A cam follower 5 is provided so as to mesh with the cam groove 2 of the traverse cam 3. That is, the cam follower 5 reciprocates on the traverse cam 3 by rotating the traverse cam 3 at a fixed interval or reversing the traverse cam 3 at a constant interval by the rotary drive source 1, and is attached to the cam follower 5. The wiper blade 6 and the wiper arm 7 are provided so as to reciprocate along the side of the glass 4 and wipe the glass surface into a rectangular shape. Reference numeral 11 is a guide rail for ensuring stable running of the cam follower 5, which is provided as necessary.

If the traverse cam 3 is made of a material having elasticity to some extent, it can be applied to curved glass having a small curvature.

Further, as shown in FIG. 2, a traverse cam 3 is laid in the cylindrical axis direction even for a curved glass having a large curvature or a cylindrical curved glass which cannot be wiped by an existing wiper, and a wiper blade 6 matching the curvature is provided. It can be wiped off by using it. The wiper blade 6 may be attached anywhere on the wiper arm 7, or the wiper blade 6 and the wiper arm 7 may be integrated.

FIG. 3 shows an embodiment of claim 2 of the present invention. In FIG. 3, 9 is a secondary side conductor line of the linear motor, which is laid in the wiping direction along the side of the glass 4. Reference numeral 10 denotes a primary side running conductor of the linear motor, which runs on the secondary side conductor line 9. That is, by energizing the positive / negative conversion current at regular intervals, the primary side traveling conductor 10 reciprocates on the secondary side conductor line 9, and the wiper blade 6 and the wiper arm 7 attached to the primary side traveling conductor 10 are made of glass 4. It is installed so that it runs back and forth along the sides and wipes the glass surface into a rectangular shape. The wiper blade 6 may be attached to any part of the wiper arm 7, or the wiper blade 6 and the wiper arm 7 may be integrated.

Note that curved glass with a large curvature and cylindrical curved glass, which cannot be wiped off by existing wipers, can be wiped off by laying the secondary side conductor line 9 in the axial direction of the cylinder. Since the conductor line 9 can be laid in a curved shape, by installing the secondary side conductor line 9 in the circumferential direction of a cylindrical or conical curved glass as shown in Fig. 4, it is possible to wipe along the circumference. Become.

Further, as shown in FIG. 5, by installing the secondary side conductor line 9 in a freely linear shape, it is possible to freely wipe the curved belt shape.

[0013]

[Effect of the invention]

 Since the entire surface of a windshield of a car or a train can be wiped in a rectangular shape, a wide view can be secured even when driving on a rainy day, which leads to accident prevention. In addition, since the entire field of view can be secured, the field of view can be widened on rainy weather such as tourist buses and trains with large windshields.

[0014] In addition, by installing on a window glass or outer wall of a building, a gondola is conventionally suspended to manually clean the window glass and outer wall of a building and the glass surface of a see-through elevator. It becomes possible to mechanize dangerous work in high places, and by installing it for each glass, you can freely clean windows from inside the room with a single switch, and fall accidents will be eliminated.
