Patent ID: 8919895

Claim:
A carrier device, comprising: a rail comprising a first rail element and a second rail element disposed oppositely to each other, and a pressing portion being disposed at an end of the rail; and a supporting element slidably disposed between the first rail element and the second rail element along the rail, the supporting element comprising: a supporting base having a lateral wall; and a buffer element with two ends having a lateral side as well as a first edge and a second edge disposed oppositely to each other, the two ends being disposed oppositely to each other, the lateral side, the first edge and the second edge being disposed between the two ends, one of the two ends of the buffer element relatively closer to the pressing portion having a protruded piece protruded towards the pressing portion and adapted to be pressed against the pressing portion, the buffer element being disposed on the lateral wall, the lateral side facing the lateral wall, the first edge comprising a first protruding portion, the first edge being pressed against the first rail element through the first protruding portion, the second edge being pressed against the second rail element, the material stiffness of the buffer element being less than the material stiffness of the supporting base; wherein, when the supporting element is disposed in the first rail element and the second rail element, one of the two ends of the buffer element relatively closer to the pressing portion is pressed against the pressing portion.
