【従来の技術】[Conventional technology]

炊飯ジャーの蓋はヒンジバネにより開放方向に付勢されており、蓋のロックを 解除すると蓋はその付勢力により自動的に開放される。 The lid of the rice cooker is biased in the opening direction by a hinge spring, which locks the lid. When released, the lid is automatically opened by the biasing force.

【０００３】 この場合、蓋が最大限に開放される前に適当な制動を付与することにより、蓋 が開放時の反動ではね返らないようにすることが従来から行なわれている。その 制動装置として、蓋又は炊飯ジャー本体のいずれか一方の部材に板バネを設け、 その板バネの自由端側の面を他方の部材のカム面に摺接させて制動をかけるよう にしたものが知られている。0003 In this case, by applying an appropriate brake before the lid is fully opened, Traditionally, it has been done to prevent the metal from rebounding due to the reaction when it is opened. the As a braking device, a leaf spring is provided on either the lid or the rice cooker body, The free end surface of the leaf spring is brought into sliding contact with the cam surface of the other member to apply braking. It is known what has been done.

【考案が解決しようとする課題】[Problem that the idea aims to solve]

上記の制動装置の制動力は、板バネのバネ力とカム面の摩擦係数により決定さ れる。 The braking force of the above braking device is determined by the spring force of the leaf spring and the friction coefficient of the cam surface. It will be done.

【０００５】 しかしながら、板バネの取付け強度に差があると、板バネの自由端側はバネ自 体の弾性以外に取付強度の影響を受けて撓むため、そのバネ力に差を生じる。バ ネ力に差が生じると制動力が一定せず、蓋の開き方にばらつきを生じる。[0005] However, if there is a difference in the mounting strength of the leaf spring, the free end of the leaf spring will In addition to the elasticity of the body, it bends due to the influence of the mounting strength, resulting in a difference in the spring force. Ba If there is a difference in the force applied, the braking force will not be constant, resulting in variations in the way the lid opens.

【０００６】 そこで、この考案は板バネの取付け強度の差の影響を受け難くすることにより 、蓋の開き方の均一化を図ることを課題とする。[0006] Therefore, this idea was developed by making it less susceptible to the difference in the mounting strength of the leaf springs. The goal is to create a uniform way to open the lid.

【課題を解決するための手段】[Means to solve the problem]

上記の課題を解決するために、この考案は容器本体に蓋をヒンジにより開閉自 在に取付け、その蓋に開放方向への付勢力を付与し、上記の容器本体又は蓋のい ずれか一方の部材に蓋の開閉に伴って他方の部材に摺接する板バネを取付けた開 閉蓋の制御装置において、上記板バネを取付けた部材に当該板バネの摺接面と平 行のバネ受け面を設け、上記板バネの自由端を上記バネ受け面に当てた構成とし たものである。 In order to solve the above problems, this invention has a lid that can be opened and closed automatically using a hinge on the container body. Attach it to the container body or the lid, and apply a biasing force to the lid in the opening direction. An opener with a leaf spring attached to one of the members that slides into contact with the other member when the lid is opened and closed. In the lid closing control device, the member to which the leaf spring is attached is flush with the sliding surface of the leaf spring. A row spring receiving surface is provided, and the free end of the leaf spring is placed in contact with the spring receiving surface. It is something that

【作用】[Effect]

板バネがカム面と摺接して撓みを生じても自由端側は相手部材のバネ受面で受 け止められるため、それ以上後退することがない。従って、板バネの撓み量は取 付け強度の如何にかかわらず一定になるので一定の制動力が得られる。 Even if the leaf spring slides against the cam surface and bends, the free end side will be received by the spring receiving surface of the mating member. Because you are stopped, you cannot retreat any further. Therefore, the amount of deflection of the leaf spring is Since it is constant regardless of the attachment strength, a constant braking force can be obtained.

【考案の効果】[Effect of the idea]

以上のようにこの考案に係る開閉蓋の制動装置は、摩擦力を発生される板バネ の自由端をバネ受け面により受ける構成であるため、板バネの他端における取付 け強度に差があっても、板バネの撓み量は一定になるので、制動力が安定する。 従って、蓋の開き方が均一化する効果がある。 As described above, the opening/closing lid braking device according to this invention uses a plate spring that generates frictional force. Since the free end of the leaf spring is received by the spring receiving surface, installation at the other end of the leaf spring is possible. Even if there is a difference in the strength of the leaf spring, the amount of deflection of the leaf spring is constant, so the braking force is stable. Therefore, there is an effect that the lid opens uniformly.
