ドア開閉装置。[Claims for Utility Model Registration] (1) A door opening/closing device supported via a hinge on an operation panel on the front surface of a cabinet so as to be freely openable and closable, comprising: a push button fitted into the front panel of the cabinet for push operation; A substantially disk-shaped cam plate is provided coaxially and integrally with the hinge fulcrum of the door, and has a cut groove for door locking on a part of its circumference, and a cam plate is provided at a position corresponding to the hinge fulcrum of the operation panel, a spherical body assembled so as to engage with a groove in the cam plate when the cam plate is closed; a coil spring that constantly biases the spherical body in a direction in which the spherical body engages with the groove in the cam plate; One end is pivotally attached to the back surface, and the spherical body is pressed and held in a direction in which the spherical body is brought into pressure contact with the circumferential surface of the cam plate via the coil spring, and the spherical body is pressed and deformed in a direction in which the engagement of the spherical body is released by button operation of the push button. A door opening/closing device comprising: a presser plate; (2) The door opening/closing device according to claim (1), wherein the holding plate is formed of a leaf spring material. (3) A holding cylinder that opens at the front and rear of the panel is formed at a position corresponding to the hinge fulcrum of the operation panel, and inside the holding cylinder, spheres and coil springs are arranged in front and back and are assembled, and the holding cylinder is pressed and held by a holding plate. claims
The door opening/closing device described in (1). (4) The holding plate is formed of a rigid plate material, and a second coil spring is interposed in the extension toward the back side of the sphere to bias the holding plate in the direction of holding the sphere. The door opening/closing device according to claim (3). (5) A holding tube that opens at the front and back of the panel is formed at a position corresponding to the hinge fulcrum of the operation panel, and a sphere is incorporated inside the holding tube, and a protrusion that fits into the holding tube and presses against the sphere is provided on the holding plate. forming, and
2. The door opening/closing device according to claim 1, further comprising a coil spring interposed on the free end side of the presser plate for biasing the presser plate in a direction in which the protrusion comes into pressure contact with the sphere. (6) A hole penetrating the front and back of the panel is formed at a position corresponding to the hinge fulcrum of the operation panel, a protrusion that fits into the hole is provided on the holding plate, and a sphere is integrally formed on the protrusion. Claim (1) further characterized in that a coil spring is interposed on the free end side of the presser plate, and is biased so that the spherical body of the protrusion is constantly pressed against the circumferential surface of the cam plate through the hole. The door opening/closing device described in . (7) The door opening/closing device according to claim (5) or (6), wherein the holding plate is formed of a leaf spring. (8) Claim (1) characterized in that a coil spring that biases the door in the opening direction is attached to the hinge fulcrum.
