[Problems to be solved by the invention]
In this case, in order to avoid damage to the panel 20 due to sliding between the metal lever shaft 22 and the edge of the slit 21, the knob 23 has a shape provided with an extended portion 24 projecting into the slit 21. The extension portion 24 is slid on the edge of the slit 21 to regulate the contact of the lever shaft 22 with the slit 21, thereby protecting the panel 20. However, because of this, the width of the slit 21 becomes large, so that the internal mechanism is seen from the outside, the appearance is deteriorated, and there is a disadvantage that dust easily enters.
[0005]
Therefore, an object of the present invention is to provide a lever structure capable of reducing the width of a slit without causing damage to a panel side and realizing an improved appearance and dustproof effect. It is.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is characterized in that the knob is located on the mounting side of the lever shaft, before and behind the sliding direction of the lever shaft in the slit, and the slit is wider than the lever shaft in the width direction of the slit. Are provided with projections protruding toward both end sides.
Note that the slide in the present invention is not limited to a structure in which the lever shaft moves in parallel in the slit, but also includes a structure in which the lever shaft rotates around the base end set inside the panel to move in the slit.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a table stove with a grill (hereinafter simply referred to as a "table stove") 1 to which a lever structure of the present invention is applied, and stove burners 3 and 3 are provided on the left and right sides of an upper surface of a top plate 2, respectively. A cooking pot or the like (not shown) is placed on a gotoku 4 provided around each of the burner burners 3, and an operation button 6 provided on a front panel 5 is pressed to ignite the corresponding burner burner 3. , A cooking pot and the like are heated. In addition, the front panel 5 is bent and formed in a U-shape in a cross section in which the top plate 2 protrudes forward so that spills from the cooking pot do not hit the operation buttons 6 and the like.
Further, a grill 7 for baking fish and other objects to be cooked is provided between the stove burners 3 and 3. When an operation button 8 is pressed, a grill burner (not shown) is ignited to heat the objects to be cooked. Is done. The front panel 5 is provided with a viewing window 9 for visually checking the inside of the grill storage.
[0008]
On the other hand, on the front panel 5, above the operation buttons 6 and 8, a heating power adjustment lever (hereinafter simply referred to as "lever") 10 is provided. As shown in FIGS. 2 and 3, each lever 10 has a plate-like lever shaft 12 that protrudes forward through a slit 11 provided in the front panel 5 in the left-right direction, and a lever shaft outside the front panel 5. The lever 13 has a base 13 connected to a needle (not shown) provided in a fuel gas passage to a corresponding burner. Therefore, by gripping the knob 13 and turning it in the left-right direction in the slit 11, the needle is rotated via the lever shaft 12, and the heat of the burner can be adjusted. The rear end of the knob 13 is formed in an obliquely cut shape in accordance with the inclined shape of the front panel 5.
[0009]
In addition, an insertion hole 14 for the lever shaft 12 is formed on the back surface of the knob 13, and the lever shaft 12 is inserted into the left and right sides of the insertion hole 14. Projections 15, 15 having minute projections 16, 16 (projection dimension S is about 0.1 to 0.2 mm) projecting upward and downward, respectively, are provided to project rearward. In addition, the protrusion of the projection 15 in the rear direction is long enough to be positioned in the slit 11 regardless of the position of the knob 13 on either side. Therefore, in the slit 11, even when the knob 13 moves in the vertical direction, the protruding portions 16, 16 of the protrusions 15, 15 first contact the upper and lower edges of the slit 11, thereby restricting the contact of the lever shaft 12. Will be.
[0010]
According to the table stove 1 configured as described above, the knob 13 of the lever 10 is located before and after in the sliding direction of the lever shaft 12, and is closer to both end edges of the slit 11 than the lever shaft 12 in the width direction of the slit 11. By adopting the lever structure provided with the protruding protrusions 15, 15, even if the lever 13 is operated to slide the lever 10 left and right by gripping the knob 13 for adjusting the heating power of the burner, the lever shaft 12 moves the slit 11 up and down. There is no risk of damaging the edges. In addition, the width of the slit 11 can be reduced to a dimension substantially close to the thickness of the lever shaft 12 by minimizing the protrusion dimensions of the protruding portions 16, 16 of the protrusion 15, so that the internal mechanism of the table stove 1 is difficult to see from the outside. In addition, the appearance is improved, and intrusion of dust and the like from the slit 11 can be suitably prevented. Furthermore, since these effects can be expected by a simple change in the shape of the knob 13 itself, no extra labor is required for assembling, and a rational structure that minimizes an increase in manufacturing cost is achieved.
[0011]
In the above embodiment, the present invention is applied to the lever 10 in which the lever shaft 12 turns and the knob 13 slides on a gentle arc. The same applies to a sliding lever. The shape of the projection may be thinner in the left-right direction, or may be a circle or an ellipse. The number is not limited to one each before and after the slide direction. For example, as shown in FIG. 4, two protrusions 17, 17 including portions protruding up and down of the lever shaft 12 may be arranged respectively. . Further, it is not always necessary to make contact with or close to the lever shaft. If the knob has a sufficient size and does not hinder the sliding of the lever shaft, it may be provided at a position distant from the lever shaft.
[0012]
On the other hand, the lever shaft is not limited to the one having a square cross section as in the above-described embodiment, and a shaft contact having a circular cross section or an ellipse can similarly regulate the sliding contact by the projections arranged in front and rear in the sliding direction. Further, it is not necessary to make the size of the protruding portion of the protrusion upper and lower or left and right the same as in the above-described embodiment. The protrusion dimensions of the protrusions may be appropriately changed. Further, the present invention can be similarly applied to the case where the sliding direction of the lever itself is not limited to the left and right but also the up and down.
[0013]
In addition, the knob is not limited to being made of synthetic resin, and may be made of rubber, and the knob and the projection do not necessarily need to be formed integrally.For example, a pin made of synthetic resin or rubber may be used for a metal knob. The projection of the present invention can be formed by fitting or the like.
In addition, the present invention is not limited to the heating power control lever of the table stove as in the above-described embodiment, but also includes a control lever for controlling temperature and the like in a burning appliance such as a water heater and a rice cooker, and a control lever for controlling volume and sound quality of an AV device. As long as the lever is provided with a knob at the tip of the lever shaft that penetrates the slit, the present invention can be applied regardless of the type and function of the mechanical device.
[0014]
【The invention's effect】
According to the first aspect of the present invention, even when the lever is slid, there is no possibility that the edge of the slit is damaged by the lever shaft. In addition, since the width of the slit can be reduced to a size close to the thickness of the lever shaft by minimizing the projection size of the projection, the internal mechanism is difficult to see from the outside, the appearance is improved, and dust and the like enter from the slit. Can be suitably prevented. Furthermore, these effects can be expected by a simple shape change to the knob itself, so that there is no extra assembly labor and a reasonable structure that minimizes the increase in manufacturing costs.
