Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device suitable for remotely controlling electrical components such as a temperature controller built into an electric oven.

The desired temperature of the electric oven is obtained by manually sliding a temperature control knob provided on the front panel of the electric oven to remotely control a thermostat provided inside the main body. In such operating devices, the sliding parts may not move smoothly depending on the precision of the parts and assembly, and the temperature must be adjusted frequently, and the operating force used for manual operation is not used. Since there are variations from person to person, it is easy to cause wobbling after long-term use, and the deviation from the reference point gradually increases, leading to problems such as a decline in operational function.

The present invention was developed in view of the above-mentioned problems, and is highly reliable, does not cause rattling even after long-term use, and allows for extremely smooth manual operation and the ability to accurately select the desired adjustment position. The purpose is to provide an operating device. The present invention will be described in detail below with reference to drawings showing embodiments thereof.

A straight notch hole 10 with appropriate length and width dimensions along the length direction (vertical direction) to insert the
c is formed. A rectangular parallelepiped sliding body 11 made of, for example, Teflon and having good sliding properties is slidably fitted into the housing body 10 . L-shaped sliding protrusions 11a and 11a' are integrally formed on the front surface (front side) and the rear surface (back side) of this sliding body 11, located at each of the four corners. The dimension between the tip surfaces of the sliding protrusions 11a and 11a' (respective surfaces on the front and rear sides of the device) is slightly shorter than the depth dimension of the housing body 10, and parallel to the sliding direction. The dimension between the left and right side surfaces is approximately equal to the distance between the left and right inner wall surfaces of the housing body 10.
The sliding protrusions 11a formed on the front surface of the sliding body 11 face the front inner wall surface 10d of the housing body 10, and the recesses surrounded by the sliding protrusions 11a formed at the four corners are formed in an H-shape. An elastic body 12 made of a plate spring made of, for example, a thin phosphor bronze plate is provided.

The lengthwise ends of the leaf springs 12 are aligned with the lengthwise direction of the casing body 10, and the upper and lower tips extend at an angle so as to be gradually positioned forward.
It is curved so as to be located slightly forward of the tip end surface of the sliding protrusion 11a, and functions to press and bias the sliding body 11 toward the rear of the housing 10. Further, on the front surface of the elastic body 12, a
A sliding member 13 made of a thin Teflon sheet having flexibility and sliding properties is provided.

On the other hand, in a recess surrounded by sliding protrusions 11a' formed at the four corners of the back surface of the sliding body 11, a rear end 42b of the knob support plate 42 press-fitted into the sliding body 11 is provided.
is attached to the rear surface of the sliding body 11 by a plurality of countersunk screws 14 (only one is shown in the drawing) screwed into the rear surface of the sliding body 11 at appropriately spaced positions in the length direction thereof. As shown in FIG. 4, this knob support plate 42 is bent along the wall surface of a rectangular parallelepiped space 110 formed inside the sliding body 11, and the tip portion 42a slides from the space 110. It passes through the center of the moving body 11, passes through the leaf spring 12, the sliding member 13, and the notch hole 10c, and projects forward. Rear end 4
2b is bent along the rear surface of the sliding body 11 at the rear end of the cavity 110. And this rear end portion 42b
A screw hole 42 into which the driven element 5 is screwed is formed on the back surface of the rotor. A lid 15 is disposed at the rear opening of the housing body 10 to cover the opening.
This lid body 15 is to form a housing together with the housing body 10, and is longer than the housing body 10, and the stepped upper and lower ends are provided with the mounting bolts 3.
A bolt hole 15a is formed through the bolt hole 15a. This lid body 15 has a fixing screw 1 which is passed through a hole bored in the lid body 15 and screwed into the screw hole 10b.
6 is attached to the housing body 10. The lid body 15 has a casing body 10 located at its center.
A linear, substantially oval-shaped guide hole 15b is provided which faces the notch hole 10c formed in the case when the device is attached to the device. The driven element 5 is inserted through the guide hole 15b and is screwed onto the rear end 42b of the knob support plate 42 so as to protrude from the lid 15 so as to move together with the sliding body 11. This driven element 5 has a stepped portion 5a formed in the middle of its shaft portion, the end portion thereof has a small diameter, and a thread groove is formed on the outer surface thereof. Therefore, when the driven element 5 is screwed onto the rear end 42b of the knob support plate 42 and tightened, the stepped part 5a abuts against the rear end 42b and the lid 15 and the head of the driven element 5 are tightened. A predetermined gap is formed between the portion 5b and the portion 5b. The operating rod 6 is positioned between the lid body 15 and the head 5b of the driven element 5, and is wound around the driven element 5 so as to be rotatable.
One end of the is attached.

In the present device configured as described above, the driver 4 and the driven element 5 are directly connected through the grip support plate 42, so that the operating force of the driver 4 is reliably transmitted to the driven element 5. As a result, each time the driver 4 is operated,
There is no displacement of the position of the driver 4 and the driven element 5 with respect to the reference point, and even after long-term use, there is no wobbling between the driver 4 and the driven element 5, and the driver can always be operated smoothly. Driven parts can be controlled remotely accurately. In addition, by attaching the lid 15, the housing body 1
A pressing force by a leaf spring 12 can be applied to the sliding body 11 disposed within the space. Therefore, the sliding protrusion 11 formed on the back surface of the sliding body 11
a' is pressed against the inner surface of the lid body 15, and the left and right side surfaces parallel to the sliding direction are in contact with the left and right inner wall surfaces of the housing body 10 as shown in FIG.
The sliding protrusion 11a formed on the front surface of the housing body 10 is maintained apart from the front inner wall surface 10d of the housing body 10. Then, the sliding body 11 has the left and right sides as the fourth
As shown in the figure, it is brought into contact with the left and right inner wall surfaces of the casing body 10, and the back side slides on the inner wall surface of the lid body 15 with a small contact area of the four sliding protrusions 11a' formed on the back surface. It is extremely light and can be moved smoothly. In addition, since the sliding body 11 is supported with a dynamic function by the elastic force of the leaf spring 12, dimensional tolerances in terms of component accuracy and assembly accuracy are completely absorbed, and the sliding portion is not worn. Even if this happens, the sliding body 11 moves toward the back side to compensate for this, so no rattling occurs during the entire period of use. Additionally, the leaf spring absorbs differences in operating force, ensuring smooth sliding. Furthermore, the head 5b of the driven element 5
Since a predetermined gap is secured between the cover body 15 and the cover body 15 by the elasticity of the leaf spring 12, the operating rod 6 supported by the driven element 5 is always rotatably supported in this gap, and Smooth operation lever 6
This results in a support structure with extremely low friction even in the driven part.

In this embodiment, the operating device operates the drive element 4 in the vertical direction, but it goes without saying that there is no problem in operating the drive element 4 in the horizontal direction, and the same function is achieved. Therefore, the device of the present invention does not have any direction when attached.

As detailed above, the operating device according to the present invention is
A housing in which a sliding body is slidably disposed within a housing, a driver supported by the sliding body and directly connecting a driver and a driven element protrudes from one surface of the housing, and faces the one surface. Since the driven element protrudes from the other surface, the driving element can be operated smoothly, and a remote driven part connected to the driven element can be accurately driven. Since the driver and the driven element are directly connected, the operating force of the driver can always be reliably transmitted to the driven element. As a result, each time you operate the driver,
No positional deviation occurs between the driver and the driven element with respect to the reference point. In addition, since the sliding body is configured to slide inside the housing with the driven element side surface and both side surfaces parallel to the sliding direction in contact with the inner circumferential surface of the housing, it can be moved not only in the sliding direction but also in the left and right directions that intersect with this. smoothly even for
In addition, stable sliding can be performed, and no rattling occurs between the driver and driven element even after long-term use, resulting in high reliability over a long period of time. Therefore,
According to the present invention, it is possible to provide an operating device with a compact structure, excellent operability, and high reliability.

The operating device of the present invention is applicable not only to temperature regulators for electric ovens, but also to general electrical components that require sliding operation.
