Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is a reflective stove with a safety guard attached to the front opening of the main body facing the heat generating part provided in the main body. Relating to a guard device.

(Prior Art) Generally, in a reflective stove, a guard made of wire is attached to the front opening of the main body, which faces the heat generating part provided in the main body. This guard is usually provided so as to be openable and closable with respect to the front opening of the main body using one side as a pivot, and various structures are used as means for fixing the guard in the closed state.

For example, using a guard spring in the form of a leaf spring,
There are some types that fix the guard to the main body side due to its elasticity. However, with this structure, the guard spring is a separate part from the guard, which increases the parts and processing costs.Also, when cleaning or otherwise maintaining the stove, there is a risk of injury from touching the edge of the guard spring. There is a risk. Furthermore, the guard spring itself is easily deformed and may lose its fixing function at an early stage.

There is also a guard that is partially deformed and fixed to the main body using the elasticity of the wire. However, with this structure, the shape of the guard becomes complicated,
It is difficult to process them, and furthermore, it is difficult to stack them for parts storage, making it troublesome to manage the parts.

There is also a structure in which the lower end of the vertical member on the opposite side of the hinge is inserted into a hole provided in the lower reflector, and the upper end is fixed by being pressed against the edge of the reflector by elasticity. However, this structure requires an extra hole in the lower reflector, and the area around the hole is likely to be damaged due to contact with the lower end of the vertical member during opening and closing operations. moreover,
Since the upper end of this vertical member is only in pressure contact with the reflective plate, there is a problem that it easily deforms if it is pulled strongly towards you.

(Problems to be solved by the invention) As mentioned above, in the conventional guard device,
Products that use separate parts such as guard springs require additional parts and processing costs, may cause injury during handling, or may quickly lose their fixing function.
Further, in the case where a part of the guard is deformed, there are problems such as the shape of the guard becomes complicated.

The purpose of this invention is to have a simple shape and easy parts management without using separate parts such as guard springs, and to prevent injury during handling.
Moreover, it is an object of the present invention to provide a guard device for a reflective stove equipped with a guard that performs a reliable fixing function over a long period of time.

[Effect of idea]

As described above, according to the present invention, when closing the guard to the front opening of the main body, one of the vertical members formed in parallel on both sides, which serves as the support shaft, supports the main body's axis. The upper end of the guard is locked to the locking part of the main body so that the other vertical member is tilted in the front and back direction, and the other vertical member is vertical. An elastic force is generated to cause the upper end of the other vertical member to be securely locked to the locking part on the main body side.
The guard can be securely fixed to the main body without rattling. In addition, there is no need to use separate parts such as guard springs as in the past, the number of parts is reduced, and the structure is simple, making it easy to assemble, looks good, and is easy to clean. There is no need to cut your hand due to the guard spring, which improves safety and appearance. Furthermore, unlike conventional guard springs, there is no need to worry about deformation, so it can provide a reliable fixing function over a long period of time. Furthermore, since the guard itself does not need to be deformed, it can be made with a simple shape, and parts management becomes easy.
