Abstract: An adapter for a picture frame allows a digital photo frame (DPF) to be mounted into a picture frame. A lock mechanism on the adapter engages into a catch of the DPF, and mounting pockets on the adapter engage with mounting tabs of the DPF, to lock the adapter to the DPF. A flange on the adapter is configured to engage the interior sides of the picture frame. The adapter allows the DPF to be attached to picture frames of various sizes, and picture frames utilizing various back attachment methods.

Abstract: An auto-eject foot stand assembly with multi-viewing angles for a visual device includes a foot having an axle perpendicular to the foot. The axle rotatably extends in a bracket. A gear is securely provided outside the axle and between the bracket and the foot. A spring is provided between the gear and the bracket. An elasticity plate is engaged with the gear. A locker is pivotally mounted on the bracket and operated by a metal spring plate to lock the gear. When the metal spring plate is pressed, the gear is released from the locker and the foot can be ejected under the elastic force of the spring. By the engagement between the gear and elasticity plate, the foot can be rotated and positioned at various desired viewing angels.
