An improved powered hinge (20) with an automatic locking feature proximate the ends of permissible relative angular displacement of its two hinge sections broadly includes: a stationary member (23) having a pivotal axis (x-x), and having a first slot (31) extending between opposite ends; a movable member (24) mounted for rotation about the pivotal axis relative to the stationary member, and having a second slot (34) extending between opposite ends; a driving member (28) adapted to be rotated about the pivotal axis relative to the sta¬ tionary member from one angular position to another, angular position, and having a third slot (36) extending between opposite ends; and an elongated pin (29) passing through the first, second and third slots, the pin being constrained for movement substantially parallel to the pivotal axis; the first, second and third slots being so configured and arranged that as the driv¬ ing member is rotated from the one angular position to the other angular position, the pin will be moved from substantially one end of the each of the slots to substantially the other end of each of the slots, and the movable member will be rotated about the pivotal axis relative to the stationary member.

In a portable phone including a phone body, a cover, and a hinge mechanism adapted to mechanically couple the cover to the phone body, the hinge mechanism including at least one hinge module mounted to the phone body and adapted to hinge the cover with respect to the phone body for opening and closing the cover. The hinge module includes a hinge housing having a bottom wall, and a pair of opposite lateral end walls spaced from each other in a rotating axis direction, one of the lateral walls having a hole, the hinge housing being completely opened at an upper end thereof and also having a pair of opposite longitudinal end walls spaced from each other in a direction normal to the rotating axis direction, a hinge shaft having a mountain-shaped portion provided with a pair of opposite cam surfaces at one longitudinal portion thereof and a shaft portion at the other longitudinal portion thereof, the hinge shaft being arranged in the hinge housing in such a fashion that the shaft portion extends through the hole of the hinge housing outwardly from the hinge housing and is coupled to the cover, so that it rotates together with the cover, a hinge cam arranged in the hinge housing in such a fashion that it faces the hinge shaft in the rotating axis direction, the hinge cam having, at one longitudinal portion thereof, a pair of mountain-shaped protrusions respectively provided with facing cam surfaces defining a valley-shaped portion therebetween, and, at the other longitudinal portion thereof, a mounting protrusion extending in the rotating axis direction, the hinge cam engaging at the valley-shaped portion with the mountain-shaped portion of the hinge shaft in such a fashion that it slides straight in the rotating axis direction in accordance with the rotation of the hinge shaft, and a hinge spring arranged in the hinge housing in the rotating axis direction to urge the hinge cam toward the hinge shaft in the rotating axis direction.
摘要:
A structure for the connecting sections of a baby carriage between a pair of push rods (1) and a push rod-connecting rod (2) which allows the widening and narrowing of the distance between the pair of push rod (1) in response to opening and closing operations on the baby carriage. The distance between the pair of push rods (1), when it is widened, is firmly maintained in that the connecting sections between the push rods (1) and the push rod-connecting rod (2) are locked. This locking of each connecting section is achieved when a locking sleeve (10) is downwardly displaced by the force of a spring (15), whereas it is canceled when the locking sleeve (10) is upwardly displaced against the force of the spring (15).

An electrical contact free microphone attachment for a flip-type radio phone which has a flip (201), a microphone (211) mounted in said flip, a main set, an audio circuit installed in the main set, and a connecting device (202) for connecting the flip with the main set. The invention comprises a transformer having a primary coil (212), a secondary coil (214) and a core (213). The primary coil is arranged in the flip to connect with the microphone (211). The secondary coil is arranged in the main set to connect with the audio circuit. The core is fixedly arranged in an axial hole formed in the connecting device.

摘要:
An improved handle of a pot is proposed which can be turned to its inoperative position over the pot to occupy less space during storage or transit. In use, the handle is locked in its operative position. It has a handle body (3) and a metal fitting (4) secured to the pot (1). The handle body has a tubular portion extending downwardly and the metal fitting has a tubular portion extending upwardly to receive the tubular portion of the handle body so that the handle body can be turned with respect to the metal fitting and thus to the pot within a limited angle.
