Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Utilization of the Invention] The present invention relates to a switch operating structure of an electric router for remotely operating a switch of an electric router having a built-in switch.

[Background of the invention]

As for the electric router, the applicant of the present application filed Shokai 61-105102.
No. 63-68403 and the like are well known. The former is one in which a switch mounting portion projecting forward is formed on the front surface of a housing above an end bracket having handles attached to both ends, and a switch is mounted on the switch mounting portion. The latter has a switch mounted on the upper end of the housing well above the handle.

As is well known, the electric router grasps the handle, pushes the housing downward, hits the router bit with the work material,
In this state, the housing is moved in the cutting direction to perform the cutting process.

The former switch is provided in the vicinity of the handle, but as described above, it is attached to the switch mounting portion that protrudes forward, so it is difficult to operate the switch with the handle firmly held, and the switch operator The operating direction of was perpendicular to the vertical direction, and it was difficult to operate because it was different from the direction in which the handle was moved up and down.

The latter switch operates in the same direction as moving the handle up and down, but since it is far away from the handle, it was almost impossible to operate it while holding the handle firmly.

As described above, the conventional electric router has a problem in operability of the switch. This is because there is no space for installing the switch in the housing near the end bracket,
This is because the switch is attached to the switch attaching portion protruding forward like the former, or the switch is provided at the upper end of the housing like the latter.

Therefore, as shown in FIG. 3, the switch 7 is mounted above the housing 1, the lever 5 having the actuator of the switch 7 fitted in the hole is extended vertically, and the operating portion of the lever 5 is positioned near the end bracket 2. Therefore, a configuration in which the switch 7 is remotely operated has been considered. That is, the switch 7 is turned on and off by sliding the lever 5 in the arrow direction, that is, upward.

In the remote operation of the switch having the above structure, the operating load of the switch 7 (400 gf to 500 gf in this example) is the load that can move the lever 5 to turn it on and off. That is, a phenomenon occurs in which the lever 5 is turned on and off with a very small load, and the lever 5 is turned on or off only when the lever 5 slightly bumps or contacts an object, which is a problem in terms of safety. In order to solve this, the operating load can be increased by pulling the lever 5 with, for example, a spring, but it is not possible to provide an inexpensive switch operating structure because additional parts are added.

[Purpose of device]

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to improve the operability by improving the operability by allowing the switch to be operated while firmly gripping the handle, and to provide a cheaper remote control structure for the switch. That is.

[Outline of device]

The present invention is provided in the housing near the handle, noting that there is no restriction on the installation location of the switch as long as the switch can be operated remotely and that the plate material such as resin can be restored even if it is flexed to some extent. The lever that slides vertically in the recess is formed with finger hooks at the top and bottom at a predetermined interval, and the finger hook is exposed to the outside from the space closest to the handle partitioned by the housing and the end bracket. Characterized in that the sliding parts of the housing and the lever of the housing are engaged with each other on the respective slopes, and the levers for sliding the lever up and down to remotely operate the switch built in the housing and the housing are provided with the respective slopes. Is.

[Example of device]

An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing an embodiment of an electric router having a switch operating structure of the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG.

The housing 1 incorporates an electric motor, a switch 7 and the like, which are not shown, and is integrally engaged with the end bracket 2. The lever 5 is guided by the side walls of the housing 1 and the end bracket 2 and is slidable in the arrow direction, that is, in the vertical direction.
As shown in FIG. 2, the lever 5 is provided with a finger hooking portion having protrusions vertically arranged at predetermined intervals, and the finger hooking portion is exposed in a recess provided in the housing 1 near the end bracket 2. It is located in. A hole for fitting with the actuator of the switch 7 is provided above the lever 5, and slopes 8a and 8b are provided on a part of the lever 5 and a part of the housing 1 which faces the slopes 8a and 8b is the same. Slope
9a and 9b are provided.

In the electric router configured as described above, when a load is applied to move the lever 5 downward from the state shown in FIG. 2, the slope 8b of the lever 5 slides on the slope 9a of the housing 1. That is, when the lever 5 bends in the direction A and moves downward to cross the slope 9a, the switch 7 is turned off. On the contrary, the switch 7 is turned on by pushing the lever 5 upward so that the slope 8a of the lever 5 crosses the slope 9b of the housing 1. Lever 5 as above
Since it is necessary to ride over the slopes 9a and 9b of the housing 1, the operating load increases, and the switch 7 can be prevented from being turned on or off unexpectedly.

According to the above embodiment, the finger rest of the lever 5 is the handle 4.
Since it is located in the vicinity of, the lever 5 can be operated while firmly gripping the handle 4, and the operating direction of the lever 5 is the same as the direction of moving the handle 4 up and down. The movement of the finger for operation becomes the smoothest, and as a result, the operability of the electric router can be improved. Moreover, since the switch 7 does not turn on or off unexpectedly, the safety of the electric router can be improved.

FIG. 4 shows another embodiment of the present invention in which a partially flat portion 11 is provided between the inclined surfaces 10a and 10b of the housing 1. FIG. 5 shows still another embodiment of the present invention, in which the lever 5 and the housing 1 are provided with slopes 12 to 15 for turning on and turning off and the angles of the slopes 12 to 15, respectively.
The height is changed to give a difference in the operating load.

[Effect of device]

As described above, according to the present invention, since the switch can be operated remotely, the place where the switch is installed is not restricted, the design of the electric router is facilitated, and the finger-holding part of the lever that remotely operates the switch is handled. Since it is located in the vicinity, you can operate the lever or switch while holding the handle firmly,
The operability of the electric router can be improved. Also, since the operating load of the switch can be increased, it is possible to prevent the switch from being turned on or off unexpectedly, and it is possible to enhance safety, and since it is not necessary to add other parts, an inexpensive switch operating structure can be provided. It is possible to provide operational effects such as provision.
