DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable grate which is used directly when burning fire on the ground, such as when cooking outdoors.

[0002]

2. Description of the Related Art With the spread of outdoor life in recent years, small and light fuel stoves have been developed, and campsites equipped with cooking facilities have been created. The act of burning charcoal is at the center of outdoor life and it is still a great pleasure. However, that action is not desirable from an ecological point of view.

That is, if a bonfire or charcoal fire is started on the ground, a large amount of cinders will remain. Retrieving a cinder is not easy, and even if it was completely recovered, it would not be possible to prevent scorching the ground.

[0004] In view of such circumstances, it seems that some sensible hikers, campers, and the like carry an iron plate and use it as a grate.

[0005]

However, since the iron plate is heavy and bulky, it is not suitable for carrying. In addition, the cinders are scattered around, which is not enough from an ecological point of view. Table-type charcoal stoves are also a kind of grate,
It's bulkier than an iron plate, and it's hardly portable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a direct-installed portable grate which is particularly small and lightweight and which is particularly suitable for carrying, and which does not scatter the cinders around.

[0007]

A portable grate according to the present invention is provided with a disc-shaped bottom plate and a petal-like arrangement around the bottom plate in order to surround the bottom plate. A plurality of movable pieces hinged to the peripheral edge of the bottom plate so as to fall outward and inward.

In the portable grate of the present invention, when the plurality of movable pieces are tilted outward, the grate becomes a dish,
The movable piece is formed in an inverted trapezoidal plate curved inward three-dimensionally so that the plurality of movable pieces form a dome when the movable piece is tilted inward.

The portable grate according to a third aspect of the present invention is provided with a protrusion for raising the height on the lower surface of the bottom plate.

[0010]

In the portable grate of the present invention, when one movable piece is tilted inward, the other movable pieces sequentially overlapping the movable piece are sequentially tilted inward, and as a result, the plurality of movable pieces are Compactly folded inside. Further, when the one movable piece is folded outward, the plurality of windshields are simultaneously spread around the bottom plate. Spread multiple movable pieces around the bottom plate and burn fire on them. Since the periphery of the bottom plate can be surrounded by the movable piece, scattering of the cinder can be prevented, and when the wind is strong, the movable piece can be used as a windshield.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a structure and a use state of an example of a portable fire grate embodying the present invention, FIG. 2 is a perspective view showing a state in which a movable piece of the portable grate is folded, and FIG. FIG. 3 is an enlarged perspective view showing a mounting portion of a movable piece.

The portable grate includes a disc-shaped bottom plate 10 and a plurality of movable pieces 20 disposed around the bottom plate 10 like petals. Both the bottom plate 10 and the movable piece 20 are made of a thin steel plate. As will be described later, the movable piece 20 freely falls outward and inward with the lower end as a center. The outwardly falling state is the use state in FIG. 1, and the outwardly falling state is the state in FIG.

As shown in FIG. 3, the bottom plate 10 has the same number of slits 11 as the number of movable pieces 20 at the peripheral edge. Slit 1
Numerals 1 are arranged along the peripheral edge of the bottom plate 10 at equal intervals in the circumferential direction. On the inner edge of the slit 11, a locking portion 12 curved downward is provided so as to protrude into the slit 11. As shown in FIG. 1, a plurality of projections 13 are provided at equal intervals in the circumferential direction on the lower surface of the bottom plate 10.
At the center of the upper surface of the bottom plate 10, a rod 14 for carrying is attached.

The plurality of movable pieces 20 form a smooth dome when tilted inward, and the bottom plate 1 when tilted outward.
Each of them is an inverted trapezoidal plate that is three-dimensionally curved inward so as to expand around 0 to form a dish-shaped grate.

One side of the movable piece 20 is a movable piece 2 on one side.
0, which overlaps with the other side of the movable piece 2 on the other side.
0 on one side.

As shown in FIG. 3, the lower end of the movable piece 20 projects downward, and an opening 22 is provided above the projection 21. The protrusion 21 is inserted into the slit 11 of the bottom plate 10, and the locking portion 1 inserted into the opening 22.
It is rotatably locked by 2.

The movable piece 2 is hinged at the lower end.
0 falls inward centering on the lower end part, and also falls outside.

Since the plurality of movable pieces 20 are overlapped in order, when one of the movable pieces 20 is tilted inward, the force is transmitted to the other movable pieces 20 in order, and simultaneously falls inward to close the dome shape. . In addition, when one sheet is knocked out, a plurality of movable pieces 20
Opens outward, and the portable grate becomes a dish.

In order to use the portable grate, as shown in FIG. 1, the grate is placed on the ground or on a stone, and a plurality of movable pieces 2 are placed.
Open 0 outward. In this state, a bonfire or charcoal fire is set on the grate. After use, the cinder on the grate is removed, and the plurality of movable pieces 20 are closed inward as shown in FIG. The cinders can be carried in a closed grate and carried or thrown away.

Since the fire is burned on the grate, no scorch is created on the ground. Since the projections 13 are provided on the lower surface of the bottom plate 10, heat is hardly transmitted to the ground or the like, and it can be used on a table. The rod 14 is provided on the upper surface of the bottom plate 10.
The grate can be moved during use with care.

Even when the movable piece 20 is opened, the movable piece 20 is bent upward and rises, and the grate becomes a dish, so that the cinder does not scatter around and is easily collected. If the movable piece 20 is set at an appropriate angle, scattering of the cinder can be prevented more reliably, and when the wind is strong, the movable piece 20 can be used instead of the windshield.

When the movable piece 20 is folded inward, its bulk is reduced, and it is easy to carry.

The bottom plate 10 and / or the movable piece 20 can be provided with a ventilation hole as appropriate.

[0024]

As described above, the portable fire grate according to the present invention not only does not cause scorching on the ground, but can cover the bottom plate with a plurality of movable pieces. Prevents scattering to the surroundings and facilitates recovery of the cinders. Therefore, environmental destruction due to a bonfire or the like is prevented. Moreover, since it is a direct-installation type and a plurality of movable pieces can be folded inward, it is extremely excellent in portability and does not burden hikers and campers. Further, the movable piece serves as a windshield, and is excellent in safety. Such a portable grate has never existed,
It is a new outdoor equipment that gives due consideration to the environment and can be said to be an excellent ecological product.

In the portable grate of the present invention, when a plurality of movable pieces are opened outward, the portable grate becomes like a dish, so that scattering such as cinders on the grate can be particularly effectively prevented. . When a plurality of movable pieces are folded inward, the movable piece becomes a dome, which is particularly convenient for carrying.

Since the portable grate of the present invention prevents heat from being transmitted downward, it is particularly effective in preventing scorching and can be used on a table.
