Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a door body attached to a roaster such as an open toaster.

Conventional door devices for this type of roaster are, for example,
As seen in Publication No. 4-67064, the protrusion of the link is fitted into the through hole of the inner plate, but the protrusion formed on the side wall located on the outside of the disc directly contacts the side of the link. Because of the structure in which they touch each other, there is a drawback that the protrusions damage the link surface when the link rotates for power transformation.

Therefore, the purpose of the present invention is to fit the protrusion formed on the surface plate into the pivot shaft of the arm piece to prevent the arm piece from being damaged when it rotates, and to reduce the number of parts during assembly. The purpose is to reduce the number of parts and simplify assembly.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a roaster main body that is box-shaped, and roasting heaters 3 and 3 are installed in the upper and lower parts of the roasting chamber 2, respectively, and in the middle part. A shelf member 4 on which objects to be roasted are placed is stretched.

Reference numeral 5 denotes a door body, which is pivoted on both sides of its lower side so that the front opening of the roasting chamber 2 can be opened and closed, and can be opened and closed by holding a handle 6 provided on its upper side.

Arm pieces 8, 8 are pivotally attached to both sides 7, 7 of the door body 5, and the other end portions are formed to extend toward the roasting chamber 2 side to engage with the shelf member 4. By opening and closing the door body 5, the shelf member 4 can also be slid in the front-rear direction.

That is, when the door body 5 is closed, the shelf member 4 is in a predetermined position at the back of the roasting chamber 2. By opening the door body 5, the shelf member 4 is
is configured to protrude to the front position together with the arm piece 8.

The door body 5 is composed of a front plate 9, a back plate 10, and a glass plate 11 interposed between these front and back plates,
The surface plate 9 has a window hole 12 formed approximately in the center, and the four sides of the outer periphery are bent slightly rearward to form peripheral walls 13, 13, 13, 1.
3 is formed.

The back plate 10 has a similar shape to the front plate 9, and has a window hole 12' formed approximately in the center, and the four sides of the outer periphery are bent slightly forward to form a peripheral wall 13 of the front plate 9. 13,1
Peripheral wall 14, 14.14 located along the inside of 3, 13
．． 14 is formed.

Further, in the contour part of the window hole 12' bored in the back plate 10, there is a supporting piece 15° 15.15 for holding the glass plate 11.
15 are formed, the glass plate 11 being held within the support pieces and each corner portion 16 of said glass plate 11,
16, 16, 16 are fixed to respective arc corner portions 17, 17, 17° 17 of the window hole 12',
Therefore, the glass plate 11 is fixed at a desired position when it is sandwiched between the front and back plates 9 and 10.

Then, a screw hole 18° 18 is bored in the front and back plates 9, 10 in order to attach the handle part 6 to the upper side of the door body 5,
The upper side of the door body 5 is fixed by inserting a screw 19 or the like therein and fixing the handle body 6 thereto.

Further, on the lower side of the door body 5, the arm piece 8 is held and fixed on both sides 7, 7, and a peripheral wall 1 has one end pivoting portion 20 formed on the front plate 9 and the back plate 10.
3 and the peripheral wall 14, a through hole 21 is bored in the peripheral wall 14, and one end of the arm piece 8 has a pivot portion 20.
A pivot shaft 22 made of an integrally molded hollow tube that is inserted into the through hole 21 is implanted on one side of the shaft, and the pivot shaft 22 is inserted into the through hole 21 of the peripheral wall 14 in advance. Afterwards, the circumferential wall 13 of the surface plate 9 is overlapped with the circumferential wall 14 so as to overlap.

A recess 23 formed by a hollow tube of the pivot shaft 22 is formed on the other surface of the pivot portion 2.0 at one end of the arm piece 8, and a hole is formed in the peripheral wall 13 corresponding to the recess. Part 24
is formed, and during the above-mentioned polymerization, the peripheral wall 13 bends outward with some elasticity, and the protrusion 24 bends into the recess 2.
3, and thus the lower side of the door body 5 is fixed.

As mentioned above, the door device of the present invention is used in a roaster in which a shelf member suspended in the roasting chamber can be slid in the front and rear directions by the opening and closing operation of the door body, which allows the front opening of the roasting chamber to be opened and closed. , a surface plate having a window hole formed approximately in the center of the door body and bending the four outer periphery sides backward to form a peripheral wall; a back plate having a peripheral wall formed therein and bent forward on four sides of the outer periphery to form a peripheral wall located inside the peripheral wall; is engaged with the shelf member, etc., a pivot shaft that fits into a through hole provided in the peripheral wall is implanted on one side of the pivot portion, and a protrusion formed on the peripheral wall is fitted on the other side. Since the arm piece has a concave space for closing the door, there is no need to use more tightening parts such as screws when assembling the door body, and the number of parts can be reduced, resulting in less assembly man-hours and easier mass production. A suitable door device is provided.
