Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a vibrating iron.

[Conventional technology]

Conventionally, when finishing the surface of cement work with a trowel, the trowel was operated in small increments to allow moisture to seep into the finished surface of the cement work, but this process was extremely difficult. Not only does it increase fatigue in the muscles of the arms and hands, making it unsuitable for long hours of work, but it also has the disadvantage of making it impossible to continue working for even longer periods of time.

In addition, in recent years, devices have been developed in which a battery is placed in the handle, the battery is used as a power source to vibrate the vibrating body, and the vibration force generated by the vibration source is transmitted to the mortarboard. However, (for example, see Utility Model Application Publication No. 61-17360 and Japanese Patent Application Publication No. 62-174450), these known techniques do not give sufficient consideration to the fact that extremely subtle vibrations may affect the finishing result. In addition, it is difficult to install a large motor, and sufficient consideration has not been given to the intervening position of the cushion body.In particular, work with plastering trowels is easily soiled, and the trowels are also soiled.
Furthermore, if the trowel is left unattended after work, there is a risk that it will solidify and become unusable again, but conventionally known techniques have structures that are not necessarily suitable for washing with water after work.

[Problem to be solved by the invention]

It is an object of the present invention to solve the above problems.

[Means for solving problems]

Support parts 2 and 2' are erected at appropriate positions at the rear and at appropriate positions at the center of the flat plate part 1 of the iron, which is relatively long in the longitudinal direction, wide, and relatively thin, and these vibration damping bodies are installed. A grip part 4 containing a built-in battery 3 is attached to the upper part of the interposed support parts 2 and 2' so as to be parallel to the flat plate part 1, and an opening/closing lid for removing and removing the battery is attached to the rear end of the grip part 4. 5 is arranged,
A switch 7 protected by a waterproof rubber 6 is disposed in front of the battery built into the grip part 4,
A cushion body 8 is disposed in front of the switch 7, and a vibrating body portion is positioned between the front end position of the cushion body 8 and an upper surface position slightly in front of the front end of the flat plate portion 1. A vibrating body 9 is provided at a lower front position or at a position diagonally below the lower rear position, and a motor 10 for driving the vibrating body 9 is disposed at an upper rear position or an upper front position, so that the vibrating body part is entirely The vibrating body 9 is
This is a vibrating iron formed to protect the motor 10 and the motor 10.

[Effect]

The grip part 4 of the vibrating trowel of the present invention is held by hand, the switch 7 is turned on, and the vibrating flat plate part 1 is used for surface finishing work in cement work, thereby causing the flat plate part 1 to vibrate slightly on the cement surface. This allows moisture to seep into the finished cement surface.

Example 1 The wiring 12 that connects the battery switch vibrating body and the motor is connected so as to be protected from the outside, and the motor 10 and the vibrating body 9 are mechanically connected, and the rotational movement by the motor 10 is controlled up and down. This vibrating iron is provided with a connecting part 13 such as a joint that allows the vibrating body 9 to make a desired movement such as movement or back and forth movement.

Example 2 Fig. 2 shows a vibrating iron part shown in Fig. 1 with a vibrating body added. The second vibrating body part is located in the space formed by the tilted cover body 11, and the motor 14 is disposed at the front position, and the rear part of the motor 14 is located at the front position. This is a vibrating iron having a vibrating body 15 disposed at a position, and a vibration-proofing rubber or the like interposed as a vibration damping body in the supporting parts 2, 2' interposed between the gripping part and the flat plate part.

Embodiment 3 A motor 14 is disposed at the front position, a vibrating body 15 is disposed at the rear position of the motor 14,
Support parts 2, 2' interposed between the grip part and the flat plate part
This is a vibrating iron with a vibration-proofing rubber or the like interposed as a vibration-dampening body.

〔effect〕

The subtle vibrations transmitted from the vibrating body of the vibrating trowel of the present invention to the flat plate of the trowel produce excellent finishing results during plastering, and plastering, which was one of the tasks that conventionally required extremely skill, This has the effect that even workers with relatively little experience can perform the work in a way that is no different from that of experienced workers. In addition, there is enough room in the grip to insert a powerful battery, and the battery can be easily inserted or removed by opening and closing the opening/closing lid, and the vibrating body is located in the grip that houses the battery. Since it is located in the front position via the cushion, a large motor can be placed, and the presence of the cushion body has the effect that vibrations generated in the vibrating body are not transmitted to the grip. Also, even if it gets dirty from plastering, it can be easily washed with water, making it easy to clean.

In particular, the present invention has support portions 2 at appropriate positions at the rear and at appropriate positions at the center of the flat plate portion 1 of the trowel, which is relatively long, wide and relatively thin in the longitudinal direction.
2' is set upright, and the gripping part 4 is attached to the upper position of these supporting parts 2, 2', so even if the gripping state of the gripping part 4 changes slightly, the way the force is applied to the flat plate part 1 is fixed. This has the effect of being able to apply force evenly and evenly to the entire surface of the flat plate. Furthermore, since the opening/closing lid 5 for attaching and detaching the battery is provided at the rear end of the grip portion 4, the battery can be easily attached and detached. In addition, the switch 7 is placed in front of the battery, and the switch 7 can be protected by the waterproof rubber 6, so even if the switch 7 is exposed to water from the outside, there is no risk of the operation of the switch 7 being affected. effective. Further, the vibrating body 9 is entirely covered with a cover body 11 that is inclined so as to rise from the front to the rear, and the vibrating body 9 and the motor 10 are
It has the effect of protecting the In addition, since the motor 10 is disposed diagonally above the vibrating body 9, the vibration force acts not only in the vertical direction but also in other directions, which affects the working direction of the flat plate part 1 in a complicated manner. It has the effect of allowing moisture to seep out onto the finished surface in a short period of time.
