Abstract
Abstract A supporting structure for supporting a TV set on an armrest of a seat of an aircraft or other vehicle so that the TV set can be turned in a vertical plane between an operating position outside a cavity formed in the front portion of the armrest and a housing position within the cavity, can be turned about a vertical axis at the operating position, and can be tilted with respect to the vertical axis. The supporting structure includes a hinge mechanism provided at the front upper end of the cavity, and a turning mechanism supported on the hinge mechanism and supporting the TV set so that the TV set can be turned at the operating position in both horizontal and vertical planes. A hinge pin included in the hinge mechanism is provided at one end with a diametrical through hole expanding toward the opposite open ends. One end of a locking pin, included in a locking mechanism, engages one of the open ends of the diametrical through hole of the hinge pin when the hinge pin is at a first predetermined angular position and engages the other open end of the diametrical through hole when the hinge pin is at a second angular position differing from the first predetermined angular position by an angle of about 180°. The hinge mechanism is interlocked with a shock absorbing mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
244 words
A supporting structure for supporting a TV set on an armrest of a seat so that the TV set can be turned in a vertical plane between an operating position outside a cavity formed under a cocktail tray formed in the front upper portion of the armrest and a housing position within the cavity, can be turned about a vertical axis at the operating position and can be tilted with respect to the vertical axis, said supporting structure comprising: a hinge mechanism provided at the front upper end of the cavity; and a turning mechanism supported on the hinge mechanism and supporting the TV set so that the TV set can be turned at the operating position in both horizontal and vertical planes; characterized in that a hinge pin included in the hinge mechanism is provided at its one end with a diametrical through hole expanding toward the opposite open ends, a locking pin included in a locking mechanism is provided so that the extremity of the locking pin engages one of the open ends of the diametrical through hole of the hinge pin when the hinge pin is at a first predetermined angular position and engages the other open end of the diametrical through hole of the hinge pin when the hinge pin is at a second predetermined angular position differing from the first predetermined position by an angle of about 180°, and the hinge mechanism is interlocked with a shock absorbing mechanism.

Claim 3
Dependent Claim
66 words
A supporting structure for supporting a TV set on an armrest according to claim 1, wherein the shock absorbing mechanism comprises a pinion fixedly mounted on the other end of the hinge pin, a swing lever having one end provided with a sector gear engaging the pinion, and a shock absorbing cylinder operatively connected to the other end of the swing lever by a connecting rod.
Claim 4
Dependent Claim
43 words
A supporting structure for supporting a TV set on an armrest according to claim 2, wherein the shock absorbing cylinder is connected operatively to a rack engaging the pinion fixedly mounted on the other end of the hinge pin by a connecting rod.
Claim 5
Dependent Claim
74 words
A supporting structure for supporting a TV set on an armrest according to claim 1, wherein the shock absorbing mechanism comprises a pinion fixedly mounted on the other end of the hinge pin, a swing lever having one end provided with a sector gear engaging the pinion, and an elastic shock absorbing means, such as coil spring means or damping means, connected to the other end of the swing lever by a connecting rod.
Claim 6
Dependent Claim
187 words
A supporting structure for supporting a TV set on an armrest according to claim 1, wherein the turning mechanism comprises: a ball end member consisting of a shank, and a ball formed at one end of the shank and provided with at least one radial projection; and a supporting socket unit including a tubular post member provided with a socket for receiving the ball of the ball end member in its upper end portion, a guide slot in its upper end to guide the shank of the ball end member for tilting motion and at least one guide groove formed in the inner surface of the socket to guide the radial projection of the ball of the ball end member; a holding member placed contiguously with the ball of the ball end member fitted in the tubular post member with the ball received in the socket of the tubular post member and with the shank projecting outside through the guide slot; and an elastic member placed within the tubular post member so as to press the holding member elastically against the ball of the ball end member.
Claim 7
Dependent Claim
34 words
