[Industrial applications]

 The present invention mainly relates to a barbecue stove used for cooking outdoors.

[0002]

[Prior art]

 Although various kinds of barbecue stoves are known, the object of the present invention is to equip legs 01 as shown in FIGS. 6 to 8, a container-like main body 02 which becomes a fire, a net plate and an iron plate 03. And a pair of support arm rods 04 that support the iron plate 03. Particularly, the support arm rods 04 have a convex shape and the bottom portion is removed, and the intermediate bent portion is pivotally supported on the side wall of the main body 02. It is a barbecue stove in which the upper and lower positions of the mesh plate can be adjusted by rotating the lower end portion of the support arm rod 04. The conventional structure for adjusting the rotation of the supporting arm rod 04 is composed of a receiving portion 05 fixed to the main body 01 and an operating portion 06 having a wing rod 061 for hooking the lower end portion of the supporting arm rod. Of the operating member 062 having the vertical groove 051 and the hooking groove 052 provided in the front-rear direction, and the operating portion 06 including the blade rod 061 and the operating portion 062 having the knob and the engaging member. By engaging with the groove 052, the vertical position of the operating portion 06 is adjusted, and accordingly, the degree of inclination of the support arm rod 04 hooked on the blade rod 061 is restricted and the height of the iron plate 03 or the like is adjusted. It is what

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, the receiving portion 05 and the operating portion 06 are hooked at one place, and since the operating portion is directly operated by hand, the operating portion 06 is inclined to the left and right as illustrated in FIG. It is easy, and when tilted, the blade rods 061 also naturally tilt, which causes the left and right support arm rods 04 to have different tilt angles and the iron plate 03 and the like to tilt. In addition, the height adjustment of the iron plate 03, etc. also becomes a stepwise adjustment, and it is not possible to make a delicate adjustment of the heating power to the food to be cooked. Furthermore, the support arm is supported by the vertical movement of the part extending from the pivotal support part Since the rod 04 is rotated, the vertical movement mechanism needs a mechanism for changing the rotation motion and the sliding motion, which has a drawback that it is difficult to balance the entire mechanism. Therefore, the present invention proposes an improvement of the structure of the vertical adjustment mechanism that allows the height of an iron plate or the like to be adjusted without permission and the overall mechanism can be balanced.

[0004]

[Means for Solving the Problems]

 The barbecue stove according to the present invention comprises a container-shaped main body that serves as a fire bed, a pair of support arm rods that are pivotally supported on the side wall of the main body, and have a mesh plate or an iron plate mounted on the top thereof, and each support arm. Rotating part with a worm gear shaft rod in which a small gear is mounted on the extension shaft of the shaft support projecting out of the side wall of the lower end of the rod, and gears are engraved in opposite working directions. And a drive unit for externally driving the worm gear shaft rod. Further, the drive portion is constituted by a drive handle for directly rotating the worm gear shaft or a rotary knob having a bevel gear interposed.

[0005]

[Action]

 When the drive unit is operated (rotation operation), the worm gear shaft rod rotates, causing the small gears to rotate in opposite directions, and the opposing support arm rods simultaneously rotate in the upright direction or the fall direction. By the rotation of the support arm rod, the distance between the upper and lower positions of the iron plate or the like placed on the top of the support arm rod, that is, the origin of the heat (heating source) is adjusted.

[0006]

【Example】

 Next, an embodiment of the present invention will be described. The barbecue stove of the present invention comprises a leg 1, a container-shaped main body 2, an iron plate 3, a pair of support arm rods 4, and an up-down adjusting mechanism such as an iron plate. The leg 1 is foldably attached to the main body 2, and the main body 2 is provided with an appropriate air hole 21 on the side wall and a fire tray 22 placed on the inner bottom surface. The support arm rods 4 are a pair of U-shaped members facing each other on the left and right sides of the main body 2, and the ends thereof are further bent outward, and the bent portions 41 are inserted into the holes of the side wall of the main body 2. It is pivotally supported and pivotally mounted, and the iron plate 3 is placed on top of the pivot.

The feature of the present invention resides in the vertical adjustment mechanism of the iron plate 3, and the vertical adjustment mechanism of the first embodiment illustrated in FIGS. 1 and 2 is composed of a rotary operation part 5 and a drive part 6. The rotary operation part 5 is composed of a small gear 51 and a worm gear shaft rod 52. The small gear 51 is axially mounted on a shaft support extension shaft (bent portion) 41 projecting to the outside of the lower end main body side wall of each support rod 4. The worm gear shaft rod 52 is provided integrally with the main body 2 on the cover portion 23 that covers the entire rotary operation portion 5 so that the worm gear shaft rod 52 is rotatable, and the worm gear shaft rod 52 is formed by engraving gears in opposite operation directions. It is meshed with both the small gears 51. In particular, one end of the worm gear shaft rod 52 is projected from the cover portion 23, and the projecting portion is a rectangular step surface to serve as a connecting portion 53. The driving portion 6 is formed of a handle and is fitted onto the connecting portion 53. A connectable portion 61 that can be attached is provided.

When the drive handle 6 is connected to the worm gear shaft rod 52 for rotation operation, the gear of the worm gear is formed in the opposite direction, so that the small gear 51 meshing with the worm gear shaft rod 5 is formed. Rotate in opposite directions. The rotation of the small gear 51 is to rotate the support arm rod 4 to adjust the vertical position of the iron plate 3 placed on the top of the support arm rod 4, that is, the distance to the fire source (heating source). The adjustment is stepless.

The configuration of the second embodiment illustrated in FIGS. 3 to 5 may be adopted as the drive unit of the vertical adjustment mechanism. The drive unit 7 shown in this embodiment is the rotary knob 71. And a pair of bevel gears 72, 73 that can mesh with each other. The rotary knob 71 is rotatably provided on the cover portion 23 provided on the front surface of the main body 2. The bevel gear 72 is connected to the same rotary shaft as the rotary knob 71, and the other bevel gear 73 is the rotary knob. It is engaged with the bevel gear 72 of the connection and is mounted on the worm gear shaft rod 51. Therefore, when the rotary knob 71 is rotated, the rotation of the rotary knob 71 is transmitted to the worm gear shaft 51 through the bevel gears 72 and 73, and the support arm rod 4 is rotated to adjust the vertical position of the iron plate 3 and the like. It can be carried out in stages.

[0010]

[Effect of device]

 INDUSTRIAL APPLICABILITY As described above, the present invention is a barbecue stove in which an iron plate is placed on a rotating support arm rod and the iron plate is vertically adjusted by rotating the support arm rod. A small gear is mounted on the shaft, and a worm gear shaft rod with the operating direction reversed is meshed, and this worm gear shaft rod is driven to rotate from the outside. Compared with the mechanism in which the support arm rod is rotated by further adjusting the extension part up and down, the support arm rod is directly rotated, so it is not necessary to change the vertical movement to the rotation movement. The entire mechanism was well-balanced and improved in operability.
