Claims

[Scope of utility model registration request]

This is a tilt angle adjustment device for adjusting the tilt angle of a tilting body mounted so as to be tiltable with respect to the support body, the first bracket being connected to the support body or the tilting body, and the tilting body. a second bracket connected to the body or support; a first spring means interposed between the second bracket and the first bracket to urge the tilting body to move to its maximum tilt position; a pawl that is rotatably assembled to the second bracket and releasably engages with a ratchet provided on the first bracket;
an operating lever which is rotatably assembled to the bracket and is linked to the pawl via a first cam means, and which can engage or disengage the ratchet and the pawl by rotation, and the ratchet and the pawl are brought into mesh with each other; a second spring means for biasing the operating lever in the rotational direction thereof; and a second cam means rotatably assembled to a support shaft provided coaxially with the tilting center of the tilting body. A first region of the second cam means linked to the pawl allows rotation of the operating lever to allow engagement and disengagement of the ratchet and pawl, and a second region continuous to the first region allows the operating lever to rotate. The operation lever is held in the rotation operation position to maintain the dissociation of the ratchet and the pawl, and the rotation of the operation lever is allowed in a third region continuous with the second region to engage and disengage the ratchet and the pawl. a first memory plate that allows a first memory plate of the second cam means to be attached to the first memory plate;
a stopper spring that elastically restricts the transition from one region to the second region and vice versa; a second memory plate that is integrally engaged with the first memory plate; a pair of stoppers that define the rotation amount of the second memory plate and the first memory plate; a third spring means for biasing the second memory plate in the rotational direction so as to disengage the second memory plate and to make the rotation angle zero; It is movably assembled and engages with the second memory plate integrally in the radial direction and relatively rotatably in the rotational direction, and is movable integrally with the pole in one direction and relatively movable in the other direction. a connecting plate that is connected to the pole and is moved integrally by the rotation of the pole in the disengagement direction; and a connecting plate that engages with the first memory plate to prevent relative displacement of both plates in the rotational direction. a torsion spring that biases the connection plate to zero; and a memory support that is assembled to the first bracket and restricts movement of the connection plate in the radial direction when the tilting body is moved to the maximum tilt position. Tilt angle adjustment device.
