By interposing reinforcing plates 26 and 26 such as SUS403 at the connecting portion of the sub arm 22 so that the weight of the lid 24 as a whole is reduced. And damage due to insufficient strength of the connecting portion with the sub arm 22 is prevented.

  Further, a support fitting 28 is erected in the column 18 so that the upper end protrudes above the support shaft 20, and one end of the rotary arm 21 is locked to the upper end of the support fitting 28. 2, the other end of the rotary arm 21 shown in FIG. 2 is connected to a portion located above the support shaft 20 with the lid 24 closing the opening 30 of the cooking pan 1. A plurality of stopped springs 31 are built in.

  As a result, the rotary arm 21 is always urged by the spring 31... In the opening direction of the lid 24 (counterclockwise in each figure), and the tension of the spring 31. Thus, adjustment is performed so that the lid 24 does not open without permission during cooking or the like according to the weight of the rotary arm 21, the sub arm 22, the lid 24 and the rotational resistance of the support shaft 20.

  The sub-arm 22 is restricted from rotating in the clockwise direction in each figure by abutment between its base end 37 and the distal end portion of the rotary arm 21, and the pivot shaft when the lid 24 shown in FIG. 2 is closed. The locking pin 38 is fixed to the closing direction position of the lid 24 rather than 23, one end is locked to the locking pin 38, and the other end is connected to the support shaft 23 of the rotating arm 21 via the adjusting screw 39. A spring 40 locked in the closing direction position of the lid 24 is urged to rotate in the closing direction of the lid 24.

  Thereby, the cushioning property by the spring 40 is given and the lid | cover 24 is urged | biased by the opening 30 of the cooking pan 1, and the adhesiveness of the lid | cover 24 and the opening 30 surface can be improved.

  The lid 24 is fixed to the sub arm 22 through the reinforcing plate 26 and the hanging metal fitting 41, and the hanging metal fitting 41 is pivotally supported by a rotation shaft 42 in a rotation direction orthogonal to the rotation direction of the sub arm 22 with respect to the rotation arm 21. The suspension fitting 41 is supported by the sub-arm 22 via the support fitting 43 by the rotation shaft 42, and this support fitting is further supported by the sub-arm 22 via the rotation shaft 44.

  Further, the support metal 43 is always in the direction closest to the column 18 of the main body 25 of the lid 24 by the spring 45, and the lower end portion 46 located at the lowermost position approaches the opening 30 when the rotary arm 21 is lifted and the lid 24 is opened. The tilting mechanism is constituted by these.

  The support fitting 43 is configured to be inclined at a predetermined angle indicated by α in FIG. 3 due to contact between the upper end of the support fitting 43 and the sub arm 22 or the like.

  A pressing plate 50 is fixed to the upper end of the support fitting 28, and a cam plate 53 having a cam surface 52 in contact with an arc-shaped pressing portion 51 of the pressing plate 50 is pivotally supported on the rotating arm 21. The shaft 54 is pivotally supported by the shaft 54, and the top end 55 of the rotary arm 21 is opposed to the top end portion of the support fitting 43 so as to be able to contact and separate, and the rear end 56 is the top end portion of the cam plate 53. A pusher 57 that is in contact with the shaft is mounted so as to be slidable in the axial direction.

  Thus, when the rotary arm 21 is lifted from the fully closed state of the lid 24 shown in FIG. 2 and the lid 24 is opened, the cam plate 53 is brought into contact with the rotation of the rotary arm 21 by contact between the pressing portion 51 and the cam plate 53. 2 rotates counterclockwise, and the tip 55 of the pusher 57 moves away from the support fitting 43, and the tension of the spring 45 causes the support fitting 43 to rotate around the rotation axis 44 at a predetermined angle (see FIG. 2). 3), the lid 24 is rotated at a predetermined angle, and the lower end 46 of the lid is positioned in the opening 30 so that water drops or the like adhering to the inner surface of the lid 24 during cooking are reliably cooked. Drop in 1 to prevent dirt from falling around the cooking pan such as water drops.

  4 and 5, the stopper 60 shown in FIGS. 4 and 5 is urged by a spring 61 so that it always abuts against the side surface of the rotary arm 21. When the rotary arm is inclined at a preset maximum inclination angle shown in FIG. 4, the distal end of the stopper 60 is engaged to form a locking hole 62 for locking the rotation of the rotary arm 21.

  On the other hand, when a dew tray 65 is formed between the cooking pan 1 and the support column 18 and the lower end 46 of the lid 24 is positioned outside the opening 30 of the cooking pan 1 as the rotating arm 21 rotates, the lower end thereof. The water droplets falling from 46 are received by the dew receiver 65.

  As a result, water drops or the like that have dropped from the lower end portion 46 of the lid 24 fall around the rotating shaft 4 and are scattered to contaminate them, or enter the gap to cause rust, thereby improving durability. Things can also be done.

  Further, the maximum inclination angle by the stopper 60 is such that the lower end 46 of the lid 24 is located above the dew holder 65 as shown in FIG. 4 when the rotary arm 21 is located at this maximum inclination angle. Thus, the stopper 60 prevents damage caused by the collision between the rotary arm 21 and the column 18 due to excessive rotation of the rotary arm 21, and the lower end 46 of the lid 24 when the rotary arm 21 is inclined at the maximum inclination angle. Water drops falling from the water can be reliably received by the dew receiver 65, and the water drops can be prevented from scattering.

  Thus, when opening the lid 24, the rotary arm 21 is lifted about the support shaft 20, whereby the cam plate 53 is rotated by the rotation of the rotary arm 21, and the tip 55 of the pusher 57 is separated from the support fitting 43. The lid 24 is inclined at a predetermined angle, so that when the lower end 46 of the lid 24 begins to open, the lid 24 is inclined almost at the same time inside the opening 30, and drops of water falling from the lower end 46 are dropped into the cooking pan 1. It prevents falling around the cooking pan.

  When the rotary arm 21 is lifted as it is and the maximum inclination angle is reached, the tip of the stopper 60 is automatically engaged with the locking hole 62 by the spring 61 and the rotation of the rotary arm 21 is stopped.

  On the other hand, when the rotary arm 21 is rotated, the rotation is assisted by the springs 31... And the lid 24 can be opened and closed by applying a slight force. The tension of the springs 31. It can be arbitrarily adjusted by 29.
