Title:
SHOCK ABSORPTION MECHANISM
Document Type and Number:
Japanese Patent JP2021134911
Kind Code:
A
Abstract:
To provide a shock absorption mechanism.SOLUTION: A shock absorption mechanism includes an absorption target part 10, a weight part 20, an initial movement leg part 30, and a link mechanism 40. The absorption target part 10 includes a leg 12 for target which can be in contact with a contact surface. The weight part 20 includes: a weight 21 for transmitting a kinetic energy of shock against the absorption target part; and a leg 22 for weight having a length allowing the contact surface to come into contact with substantially at the same time with the leg for target. The initial movement leg part 30 is provided so as to be initially in contact with the contact surface, and so that a longitudinal direction thereof is provided coaxially with Z axis. A link mechanism 40 having a structural specificity connects the absorption target part 10 and the weight part 20 in a movable manner at one degree of freedom in a Z-axis direction such that, when coming into contact with the contact surface of the initial movement leg part 30, shock transmitting rates from the initial movement leg part 30 to the absorption target part 10 and the weight part 20 are zero, and when coming into contact with the leg 22 for weight, a shock transmitting rate from the weight part 20 to the absorption target part 10 is zero.SELECTED DRAWING: Figure 1
