Embodiment Construction

[0020]With reference to FIGS. 1 and 2, a desk board raising apparatus in accordance with the present invention comprises a seat 10, an active module 20, a passive module 30, a cylinder 40 and a desk board module 50.

[0021]The seat 10 has a longitudinal axis, a front board 11, a rear board 12, two side boards 13, a chamber, an opening 14, and an inclined surface 15. The rear board 12 is opposite to the front board 11. The side boards 13 are connected with the front board 11 and the rear board 12. Each side board 13 has a chute 16. The chamber is defined in the seat 10 and is enclosed by the front board 11, the rear board 12 and the side boards 13. The opening 14 is defined in a top surface of the seat 10 and is in communication with the chamber. The inclined surface 15 is defined on a front surface of the front board 11 and inclines to a bottom end of the rear board 12 to provide an active space. Each chute 16 has a locating segment close to a top end of the front board 11. The chutes...

Abstract

A desk board raising apparatus has a seat, an active module, a passive module, and a cylinder. The active module is pivotally mounted in the seat and has a base, two linking arms, and a pivot. The linking arms are L-shaped. The pivot is deposited between the linking arms and pivotally mounted in the seat. The passive module is mounted in the seat and has a passive board pivotally connected with the linking arms. The cylinder is mounted in the seat and is adapted to push the passive board. Thus, the base lifted up or down can drive the passive board to move up or down. Therefore, the desk board raising apparatus uses a simple structure to synchronize the movements of the passive board and the base, and therefore has the advantages of convenient operation, low manufacturing cost, low maintenance cost, and consuming no power.
