Abstract

A damping enclosure includes a hollow resilient enclosure, multiple resilient balls movably received in the enclosure, and fluid inside the enclosure. With the rotation of the balls and the fluid inside the enclosure, a force is effectively dispersed and damped.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a damping enclosure, and more particularly to a damping enclosure to damp or decrease shock on the damping enclosure.
  • 2. Description of Related Art
  • Current damping devices such as sand bags, air pads or rubber materials directly damp the shock by their material features, which has little effect to disperse the shock such that after a long period of time of continuously using the damping device, the damping devices are gradually worn out or damaged.
  • To overcome the shortcomings, the present invention tends to provide an improved damping enclosure to mitigate the aforementioned problems.
    • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide an improved damping enclosure to damp or decrease the shock by the resilient balls and fluid inside the enclosure such that the shock dispersion effect is good and thus the life span of the damping enclosure is prolonged.
  • Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
    • BRIEF DESCRIPTION OF THE DRAWINGS

    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIGS. 1, 2 and 3, the damping enclosure in accordance with the present invention includes an enclosure (10), balls (20) of different dimensions and fluid (22).
  • The enclosure (10) is made of resilient material and is hollow so as to receive therein the balls (20). The enclosure (10) has multiple through holes defined through a periphery of the enclosure (10) so that the inner space of the enclosure (10) is able to communicate with ambient air outside the enclosure (10). Preferably, the enclosure (10) is a sphere.
  • The balls (20) are of different dimensions and made of resilient material. The balls (20) are received inside the enclosure (10) with the fluid (22) also received inside the enclosure (10). With the combination of the enclosure (10), the balls (20) and the fluid (22), the damping enclosure of the present invention is able to provide powerful shock damping effect.
  • With reference to FIGS. 4 and 5, when a force as indicated by the arrow is acting on the damping enclosure of the present invention, the force is dispersed to each and every one of the balls (20). With the rotation and movement of the balls (20), the damping effect of the fluid (22) itself and the deformation of the enclosure (10), the force is effectively damped. It is noted that the in order to maintain the effective function of the damping enclosure of the present invention, when the fluid (22) inside the damping enclosure is air, the dimension of the through holes (12) is the same as the fluid (22) and when the fluid (22) inside the damping enclosure is liquid, the dimension of the through holes (12) is smaller than the dimension of the fluid.
  • With reference to FIGS. 6-8, it is noted that a plate (30) having multiple recessed areas (32) of different dimensions is provided to receive therein the damping enclosure of the present invention. That is, the damping enclosure is arranged to have different dimensions to correspond to the multiple recessed areas (32). After multiple plates (30) with multiple damping enclosures received in the plates (30) are stacked together and a cover (40) is provided to enclose the combination of the plates (30) and the damping enclosures of the present invention, the entire combination of the damping enclosures (10), the plates (30) and the cover (40) is to function as a vehicle bumper, the damping effect is far greater than the current rubber damper. Furthermore, the cover (40) has apertures (42) defined in a side face thereof to allow air escape when an impact is applied to the cover (40).
  • With reference to FIG. 9, it is noted that multiple damping enclosures are received in a container (50) as a cushion in a harbor to prevent direct collision of vessels with the dock.
  • It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
