Description

[Detailed Description of the Invention] The present invention relates to a fall safety device for electric heating appliances such as electric stoves.

Taking a conventional electric stove as an example, the first
The figure shows how the movable shaft 4 and side plate 10 of the conventional overturn safety switch 1 are attached. Align the movable shaft 4 with the U groove 19 provided inside the side plate 10, and attach the mounting bracket 2.
0, and the mounting screws 21 passing through the mounting fittings 20 were screwed into the side plate 10 for installation. For this reason, in addition to the side plate 10 and the movable shaft 4, a mounting bracket 20 and a mounting screw 21 are required, which increases the cost of parts and also requires the use of the U-groove 19 during installation.
and movable shaft 4, side plate 10 and mounting bracket 20.
, alignment of the screw holes in the side plate 10 and the mounting screws 21 , and tightening of the mounting screws 21 , which resulted in a large loss in terms of cost and work.

The present invention was developed to eliminate the above-mentioned drawbacks, and improves the mounting structure of the movable shaft, which is a component of the fall safety switch, to improve cost and workability, and to create a structure that is more effective in terms of safety management. The goal is to provide the following.

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

The configuration of the embodiment is as shown in FIGS. 2 to 6. Reference numeral 4 denotes a movable shaft, which is made of an elastic material such as polypropylene resin, and as shown in FIG. It is integrated with the cap portion 8. The cap portion 8 is provided with a plurality of wedge-shaped fin portions 16 extending upward and having restorability. A holding hole 15 that fits with the sliding part 6 of the movable shaft 4 is provided in the mounting part of the movable shaft 4 of the side plate 10, and the sliding part 6 of the movable shaft 4
hold. Reference numeral 18 denotes a peephole, which is opened at the side of the holding hole 15 of the side plate 10 and facing the outside, as shown in FIG. 4, and is provided so as to face the central portion of the movable shaft 4. Also, the upper surface 11 of the upper end of the holding hole 15 of the side plate 10
A small hole 17 is provided opposite to the holding hole 15, and the wedge-shaped fin portion 16 of the movable shaft 4 passes through the small hole 17.
When the movable shaft 4 is restored, the movable shaft 4 is locked and the range of vertical sliding movement is restricted.

To explain the operation of this embodiment, first, during assembly, the movable shaft 4 is inserted into the holding hole 15 from below the side plate 10, and the fin part 16 of the cap part 8 is inserted into the side plate 10.
The fin part 16 is pushed in while being bent inward by the small hole 17, and when it passes through the small hole 17 and emerges from the upper surface 11, the fin part 16
is restored and becomes larger than the small hole 17, and the movable shaft 4 is prevented from descending and escaping. In addition, the movable shaft 4 has a sliding portion 6
Since it has a rectangular shape, it is prevented from rotating. In this way, the movable shaft 4 that slides up and down can be confirmed from the outside through the viewing window 18 opened on the side surface of the side plate 10. If the body of the electric heating appliance falls over, the contact plate 14 of the switch attached to the body 2
presses the upper end 13 of the movable shaft 4, and the fin 16 of the movable shaft 4 comes into contact with the small hole 17 of the side plate and is locked.
At this time, the contact of the switch becomes open. On the other hand, when the container body is in a normal state, the lower end 12 of the movable shaft 4 is pressed by the floor, so that the end of the sliding part 4 of the movable shaft 4 hits the small hole 17 of the side plate 10. Close the contact of the switch. Therefore,
The movable shaft 4 is movable using the small hole 17 of the side plate 10 as a stopper, and its movable range is restricted.

According to the present invention, the neck part and the sliding part are connected to the cap part forming the fin part made of an elastic material on the side plate of the container body, which has a small hole and a holding hole larger than the small hole facing each other. Fitting and inserting the integrally formed movable shaft, positioning the neck of the movable shaft in the small hole of the side plate, and positioning the sliding part in the holding hole,
The movable range of the movable shaft is defined by the fin of the movable shaft,
The movable shaft that opens and closes the contacts of the fall safety switch can be installed securely with a single touch by providing the sliding part and the small hole in the side plate to restrict the movement.This eliminates the need for mounting brackets and mounting screws, improving work efficiency. We were able to improve this and reduce costs. Additionally, the viewing window allows the installation and sliding status of the movable shaft to be confirmed from the outside of the side, improving safety.
