Description

Height-adjustable barbecue grill {CHARCOAL-CASE ADJUSTABLE TYPE BARBECUE GRILL}

The present invention relates to a height-adjustable barbecue grill, and more particularly, to a grill whose height can be adjusted with little force by using a pulley and a weight.

As various outdoor leisure activities such as auto camping, glamping, backpacking, and bicycle camping become more active and camping culture expands, charcoal grills (hereinafter referred to as 'barbecue grills') that use charcoal among outdoor cooking equipment for enjoying cooking outdoors at pensions and other places are also being supplied and widely used in various ways.

As such, barbecue grills, which are widely used in outdoor activities, are designed to allow the use of heat by adjusting the type of grilled material and preference. However, barbecue grills that use charcoal are not easy to control the heat unlike general electric barbecue grills due to the type and characteristics of the charcoal, which makes grilling difficult.

Below, we will look at conventional barbecue grills through references.

Reference 1 discloses a multipurpose charcoal grill that is foldable for convenient use outdoors, making it easy to carry and store, and furthermore, allows the height of the charcoal case for storing charcoal to be easily adjusted, thereby preventing meat, fish, and other food ingredients from burning during the cooking process and providing convenience to the user.

Reference document 2; A barbecue grill device is disclosed in which a foldable top plate member is installed on the upper part of a grill body, a grill member in which a frame and a grill bar are separated on the upper side of the top plate member and most of the oil is naturally discharged to the outside when grilling meat, and a height-adjusting member is configured on the grill member so that the installation height of the grill member can be adjusted according to the strength of the charcoal fire.

Reference 3; A charcoal barbecue grill is disclosed that can be folded into a small size for easy transport and storage, can be conveniently used by unfolding the folding plate installed on the barbecue grill itself without a separate table, and allows the height of the charcoal grill stand installed inside the grill to be easily adjusted from the outside, thereby enabling the most appropriate fire intensity to be controlled depending on the type of meat, preference, or fire power.

Reference document 4 discloses a charcoal grill, which comprises a left and right rotating plate in which an insertion hole for inserting a food holder and an insertion groove are formed equilaterally on a circumference and an axial portion installed at the center of the left and right rotating plates, and which allows a selection to cook using charcoal grilling with a griddle plate on the upper part of the main body or using the barbecue grill.

In addition, reference document 5 discloses a grill for grilling, which has a fire tray and an ash tray in a wall hole of the grill body, and allows the position of the fire to be adjusted by opening and closing the fire tray in a drawer-like manner, and reference document 6 discloses a grill oven capable of barbecue cooking, which allows not only general grilling and stew cooking, but also barbecue, smoking, and auxiliary cooking such as stew at the same time.

As examined, existing barbecue grills were used by adjusting the height of the grill plate (grinding plate) depending on the intensity of the fire, etc., which resulted in safety accidents and inconveniences in use due to the movement of the grill plate placed on top of the grill body.

In addition, existing barbecue grills are structured so that the charcoal container and the support that supports the charcoal container cannot be disassembled and assembled from the grill body, or even if the structure allows disassembly and assembly, the work is not easy, and there are many difficulties in emptying and cleaning the charcoal container and charcoal container holder inside the grill body.

Referring to FIGS. 1 to 8, a height-adjustable barbecue grill (1000) according to the present invention includes a fire part (100), a grill part (200), a height-adjusting part (300), and a support frame (400).

The furnace (100) forms a space where solid fuel is burned. In the illustrated embodiment, the furnace (100) has a rectangular plate shape, but this is only one of the possible shapes, and the shape of the furnace (100) is not limited.

The grill part (200) is placed on the upper side of the furnace part (100) to receive combustion heat directly, and forms a space where food is cooked. The grill part (200) has a size and shape corresponding to the furnace part (100). The grill part (200) may be equipped with a handle (210) for adjusting the distance from the furnace part (100) (i.e., raising and lowering). In addition, a lid (220) that can be detached/combined may be further equipped on the upper surface.

The height adjustment unit (300) adjusts the gap between the furnace unit (100) and the grill unit (200). Since it is difficult to adjust the intensity of the firepower of solid fuel in real time, the firepower adjustment required for cooking food is performed by adjusting the gap between the furnace unit (100) and the grill unit (200).

The height adjustment unit (300) includes a lifting frame (310) and a lifting bracket (320).

The lifting frame (310) is positioned vertically with respect to the ground on the side of the furnace (100).

The lifting bracket (320) is connected to the grill part (200), moves up and down along the lifting frame (310) depending on the operation, and is fixed at a specific position of the lifting frame (310) by the weight of the grill part (200).

Since the grill part (200) is placed directly above the furnace part (100), the lifting bracket (320) is placed on the side facing the furnace part (the left side of the lifting bracket based on the city). It is fixed by a bolt/nut combination.

The elevator frame (310) is formed by bending a steel plate and includes a rectangular column (F) having a shape corresponding to a rectangular cross section, a pair of catch rails (311-L, 311-R), a weight (312), a pulley (313), and a wire (314).

The catch rail (311-L, 311-R) has teeth (T) protruding at regular intervals and is arranged in a pair of left-right symmetrical shapes.

The catch rails (311-L, 311-R) are arranged so that the teeth (T) face the rear side opposite to the part where the grill part (200) is joined - that is, the rear side (left side based on the city standard) of the angle pillar (F).

A pair of catch rails (311-L, 311-R) are arranged in a parallel form with a certain interval. The teeth (T) have an asymmetrical form with the protruding upper surface facing horizontally. The interval between the teeth (T) is the unit interval at which the height is adjusted. It is preferable that the interval between the teeth (T) is 1 cm to 2 cm.

The weight (312) is placed between the hanging rails (311-L, 311-R), and is preferably in the form of stacked unit weights. The balance with the grill part (200) can be adjusted by adding or subtracting the unit weight according to the weight of the grill part (200).

The dorre (313) is provided on the upper end of the catch rail (311-L, 311-R). It is preferable to place it in the space between the catch rails (311-L, 311-R).

The wire (314) connects the weight (212) and the lifting bracket (320) via the pulley (313). Since the grill part (200) is fixed to the lifting bracket (320), the force used by the user to adjust the height of the grill part (200) is the weight of the grill part (200) + the weight of the lifting bracket (320) minus the weight of the weight (212). Therefore, the height of the grill part (200) can be adjusted with a small amount of force by adjusting the weight (212).

The lifting bracket (320) includes a cover (C), a first crossbar (321), a second crossbar (322), a first roller (R1), and a second roller (R2).

The cover (C) is a pair of catch rails (311-L, 311-R) - i.e., surrounding the lifting frame (310). It has a cross-section of the form. For convenience of explanation, the open part of the cover (C) is called the front (right side of the city).

The cover (C) is inserted in a form that faces the front from the rear where the catch rails (311-L, 311-R) are arranged, and a grill part (200) is fixed to the open part in a bolt-nut manner to surround the lifting frame (310).

The first crossbar (321) connects the inner surfaces of both sides of the cover (C) at the lower front side of the cover (C) so that the lifting frame (310) is confined to the inner side of the cover (C).

The second crossbar (322) connects the inner surfaces of both sides of the cover (C) at the upper rear surface of the cover (C) so as to be caught by the teeth (T).

A pair of first rollers (R1) are provided on each of the front inner sides of the cover (C). The first rollers (R1) come into contact with the front of each column (F) when the lifting frame (310) is tilted for lifting.

The second roller (R2) is provided with a pair of covers (C) on the rear inner side, respectively. The second roller (R1) maintains contact with the rear of each column (F) while the lifting frame (310) is fixed.

The lifting bracket (320) is tilted based on the first crossbar (321), and the first crossbar (322) and the second crossbar (322) are arranged so that the horizontal distance is the same as the distance between the front surface of the lifting frame (310) and the bottom surface of the gear (T).

When the second crossbar (322) is fixed in a form supported by the teeth (T), the second crossbar (322) acts as a tilt axis, and the force for the grille part (200) to descend is supported by the first crossbar (321) on the front side of the lifting frame (310) (i.e., the front side of the column (F)) so that the grille part (200) is fixed while maintaining the horizontal position.

When the user lifts the handle (210) to disengage the second crossbar (322) from the gear (T), the lifting frame (310) becomes free and can be raised or lowered by the user's force. By the user's tilt, the first roller (R1) comes into contact with the front of the column (F) and the second roller (R2) comes into contact with the back of the column (F), so that smooth lifting is achieved. In addition, since the tilt range is controlled by the first roller (R1) only enough to disengage the second crossbar (322) from the gear (T), the lifting frame (310) can be fixed simply by the user's slight manipulation of holding the handle (210).

The support frame (400) is for the durability of the height-adjustable barbecue grill (1000), and is a frame on which the fire part (100), grill part (200), and height-adjusting part (300) are supported.

Since the grill part (200) is fixed to the height adjustment part (300), it is preferable that the upper and lower ends of the lifting frame (310) be fixed to the mounting frame (400) for durability.

The embodiments of the present invention disclosed in this specification and drawings are merely specific examples presented to easily explain the technical content of the present invention and to help understand the present invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art to which the present invention pertains that other modified examples based on the technical idea of the present invention can be implemented in addition to the embodiments disclosed herein.
