[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, as illustrated in FIGS. 5 to 7, provided with legs 01, a container-like main body 02 serving as 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 and the like also becomes a stepwise adjustment, and it is not possible to make a delicate adjustment of the heat power to the food to be cooked. For this reason, the applicant of the present application has previously made a proposal (actual application No. 6-1512) in which the vertical position adjusting unit employs a screw shaft portion and an up-and-down operating portion screwed to the screw shaft portion to enable uninterrupted floor adjustment. . Since the drive handle that is continuous with the screw shaft is used for the adjustment drive for the above-mentioned unauthorized floor adjustment, the handle protrudes from the main body and is inconvenient to handle, and a folding mechanism is also used for compact storage. Although it is possible to make it possible, the cost will increase due to the complicated structure of the parts. Furthermore, since the handle was operated from the bottom of the main body, and the operating part and the part adjusted by the operation (distance between the amount of heat in the main body and the iron plate) were far apart, so it could not be said that the operability was necessarily excellent. Therefore, the present invention proposes a stove with improved operability in vertical adjustment of a steel net plate or the like.

[0004]

[Means for Solving the Problems]

 The barbecue stove according to the present invention comprises a container-shaped main body which serves as a fire bed, a pair of support arm rods which are pivotally supported on the side wall of the main body, and on which a mesh plate or an iron plate is placed, and outside the side wall of the main body. In a barbecue stove equipped with a vertical position adjusting part such as a net plate or an iron plate that moves the lower end part of the supporting arm rod which is extended and protrudes upward and downward to rotate the supporting arm bar, the vertical position adjustment of the iron plate etc. The screw shaft is rotatably installed vertically in the center of the front part of the main body, the vertical operating part that is screwed onto the screw shaft, and the lower end of the supporting arm rod by projecting to the left and right of the vertical operating part. It is characterized in that it is composed of a wing rod portion to be hooked and a drive portion in which one of meshing bevel gears is mounted on a screw shaft portion and the other is connected to a rotary knob provided on the front surface of the main body. is there.

[0005]

[Action]

 When the rotary knob located on the front surface of the main body is rotated, the bevel gear is rotated and the screw shaft portion is rotated, and accordingly, the vertical operation portion and the blade rod portion are moved up and down to rotate the support arm rod. . By the rotation of the supporting arm rod, the vertical position of the iron plate or the like placed on the top of the supporting arm rod, that is, the distance from the fire source (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 supporting arm rods 4 are a pair of members facing each other on the left and right sides of the main body 2. The supporting arm rods 4 have a convex shape with the bottom portion removed, and the middle bent portion is formed in the hole of the side wall of the main body 2. It has an insertion shaft and is rotatable, and an iron plate 3 is placed on the top thereof.

A feature of the present invention resides in a vertical adjusting mechanism for the iron plate 3, which is composed of a screw shaft portion 5, a vertical operating portion 6, a blade rod portion 7, and a driving portion 8. The screw shaft portion 5 includes a screw shaft 51 and a bearing ball 5 that is embedded by embedding a vertical hole 52 in one end surface of the screw shaft 51 in a cover portion (fixed portion) 23 provided in the center of the front surface of the main body 2. 3 and a supporting body 54 protruding from the fixed portion and having its tip abutting only on the bearing ball 53. A vertically rotatable screw shaft 51 is rotated by the rotation operation of the drive unit 8. It is the one to be confused. The up-and-down operating part 6 is provided in the cover part 23 so as to be vertically movable, and is screwed with the screw shaft part 5 so as to move up and down by the rotation of the screw shaft 51. The wing rods 7 are provided on the left and right sides of the up-and-down operating unit 6, and hook the lower end of the support arm rod 4. The drive unit 8 includes a rotary knob 81 rotatably held and formed on the front surface of the cover unit 23, a bevel gear 82 coaxially connected to the rotary knob 81, and a bevel gear 82 mounted on the screw shaft 51. The bevel gear 83 meshes with each other, and the screw shaft 51 is rotated by the rotation of the rotary knob 81.

Therefore, when the rotary knob 81 of the drive portion 8 provided on the cover portion 23 on the front surface of the main body 2 is operated to rotate, the blade rod portion 7 moves up and down together with the up-and-down operating portion 6 and is hooked on the blade rod portion 7. The vertical position of the lowermost end of the supporting arm rod 4 is also changed to determine the tilt angle of the supporting arm rod 4. That is, the support arm rod 4 is rotated by the rotation of the drive portion 8, and the vertical position of the iron plate 3 placed on the top of the support arm rod 4, that is, the distance from the fire source (heating source) is continuously adjusted. It is.

If a bearing member such as a bearing ball 53 is interposed in supporting the screw shaft 51 on a fixed portion, the rotation adjusting operation itself can be performed with a very light force, and the dish is placed on an iron plate or the like. Even in the open state, the thermal power can be easily adjusted.
