Description

  The present invention relates to a handle mounting structure for a one-handed pan used during cooking.

  The one-handed pan for cooking is a fitting that is integrally molded with a synthetic resin handle on the outer periphery of the pan, and is attached almost horizontally toward the outside with reference to the upper end surface of the outer periphery of the pan. It is known that there are some structures.

  One-handed pans are easy to use, but because the handle is long and the handle is far away from the center of gravity of the pan, the load on the handle is unstable and difficult to handle when carrying cooking utensils in the pan. Therefore, the size of the pan is limited, and although it depends on the use conditions, in general, a relatively small size is a one-handed pan, and when the size is large, a two-handed pan is often used.

  Furthermore, since the handle of the one-handed pan protrudes longer than the outer peripheral surface of the pan body, the handle becomes obstructive except when the handle is held during cooking, and depending on the position, it is dangerous to hit the body.

Therefore, various proposals have been made to solve this problem.
For example, Patent Document 1 already filed by the applicant describes a configuration in which the handle is positioned above the outer peripheral surface of the pan toward the upper center of the pan in order to reduce the load on the handle of the one-handed pan. .

  Patent Document 2 describes a structure in which a handle that is curved from the outer peripheral surface of a container that is mainly used as a kettle as a cooking utensil is attached toward the upper center of the container, and the handle is removable. .

  Patent Documents 3 to 5 describe a structure in which the handle is long and straight, and the handle is detachable from the pan body.

  Further, Patent Document 6 is a pan lid handle that can be rotated 360 ° and can be locked at a predetermined rotational position. A spring plate is incorporated in the rotating portion and is perpendicular to the axial direction of the lower end portion of the handle body. A structure is described in which the handle main body is rotated every 90 ° by being engaged with the spring plate with a structure having a short cross section.

  Further, in Patent Document 7, an oblong hole of a hinge is provided between the pan body and the handle so that the hinge pivots substantially horizontally, and when the distance between the two is reduced, the fitting portion is fitted, and the access portion Is fixed with bolts and nuts like a flange, and the handle is folded when stored.

  As disclosed in Patent Documents 1 and 2, the load applied to the handle in the structure in which the handle is fixed at the position above the outer peripheral surface of the pot toward the upper center of the pot or the position above the center of the pot. Can be halved, and the handle does not protrude into the outer periphery of the pan and does not hit the body. However, there is a problem that when the ingredients are put into the pan during cooking, the handle becomes obstructive and cooking is difficult. Further, in Patent Document 2, since the handle is in the center of the pan, there is a problem that when cooking with the utensil, the handle becomes hot with steam and cooking is difficult when the lid is opened.

  In the disclosure of Patent Documents 3 to 5, the handle is detachable from the pan body, and the handle can be detached from the pan body during cooking. Because it is far away, the load on the handle is large and unstable when carrying it in a pot. Furthermore, the attachment / detachment structure is complicated, and the number of parts is considered to be high.

  In Patent Document 6, the handle is rotated 360 °, and the position of the handle can be arbitrarily changed. However, the handle only rotates in a horizontal state and is easy to use if used as a pan lid, but is used as a pan. In this case, when throwing away the hot water after cooking, there is a problem that when the pan is tilted, the handle locked by the spring pressure rotates freely due to the gravity of the pan and the hot water, and the hot water spills out.

  In Patent Document 7, since the handle is long, the handle is turned and folded, and brought close to the pan. However, for the purpose of compact storage, the handle cannot be fulfilled when folded.

  Therefore, the problem to be solved by the present invention is that the load on the handle can be halved with a single handle, and the handle is located at the position above the outer peripheral surface of the pan toward the upper center of the pan. Depending on the situation, a handle mechanism that allows the handle to move in an oblique handle state from the upper outer periphery of the pan to the lower outer side is combined with a structure that can be easily attached to and detached from the pan body, and that can be manufactured inexpensively with fewer parts.

The two functions can be used arbitrarily.

In the one-handed pan of the swing handle of the prototype, when cooking with cooking utensils, the grip 5 does not get in the way of the outer periphery of the pan 1 and the outer lower position, as shown in FIG. For example, when throwing away the hot water of the noodles that have been boiled, the handle 5 was swung in the position above the outer periphery of the pan 1, as shown in FIG. However, since the surface temperature of the grip portion 51 of the handle 5 when hot water most concerned during cooking boiled and the handle due to steam when the boiled hot water is discarded, there is an influence on the handle. The prototype was used and the experiment was conducted as follows.
The pan 1 has a diameter of 200 mm and a depth of 105 mm, and the position of the grip 51 is vertically 65 mm above the upper end of the outer peripheral surface of the pan 1, and the position of the center lower end of the grip 51 is in the state shown in FIG. Bring about 3 liters of 90% water into the pan 1 and boil it. Remove the lid 13 and keep boiling for 5 minutes with the steam directly hitting the grip 51. From the top end of the outer peripheral surface of the pan 1 vertically The measurement was performed at a position where the temperature of the lower end of the center of the handle 5 was highest 65 mm above. As a result of testing three times, the surface temperature of the grip 51 was 38 ° C to 39 ° C. Moreover, the space temperature in the state where the steam was rising at the same position was 43 ° C. to 45 ° C. Furthermore, when the grip 51 is lifted in the state of boiling hot water, the tip of the grip 51 is directed downward, the pan 1 is tilted 90 ° sideways, and the hot water is discarded, the time for the steam to hit the handle is short. For this reason, the hand holding the grip 51 feels a little hot, but it was not a problem. Similar results were obtained after three tests under the same conditions. Accordingly, there is no particular problem as long as the position of the grip 51 is in the above-described range.
Assuming that the grip portion 51 is in the center of the pan 1, the thermometer is set at the center of the pan 1 at 65 mm upward with the upper end of the outer periphery of the pan 1 as a horizontal reference with the same height as described above. As a result of boiling the hot water under the same conditions as above and measuring the temperature of the space where the steam is rising three times as described above, the temperature was 61 ° C. to 64 ° C. When the grip 51 is in the center of the pan 1, steam at this temperature is applied to the grip 51, so when the hot water is boiling or immediately after that, hold the pan 51 with the grip 51. Lifting and throwing away hot water is considered difficult. Therefore, the position of the handle 5 is preferably FIG. 1 above the outer peripheral surface of the pan 1.
