The present invention provides a robot which is suitable for travel through a pipeline. The inventive robot comprises at least one tracked drive means and at least one roller means that can swivel about an axis substantially normal to a rolling axis thereof, wherein said at least one tracked drive means and at least one roller means are provided with magnetic means for generating a magnetic adhesion force between the robot and an internal wall of the pipeline.

The present invention provides one or more carrier devices capable of varying contact damping with pressured displacement. The device is configured to be installed on mechanical force-receiving structures that have rolling wheels, rolling balls or slidably displaceable terminal block structure, carrying devices and transportation devices for humans or objects. When receiving pressure smaller than a set value, the device provides low contact damping and is thus easy to move. On the other hand, when receiving pressure greater than the set value, it provides high contact damping so as to prevent slip and thereby ensure safe placement. In addition, when receiving pressure smaller than the set value, the device has its pre-stressed structure generate modulation to displacement corresponding to the size of the pressure it receives for the purpose of shock absorbency.

A universal rotating module is provided. The universal rotating module comprises a suspension carrier, a top cover, a globular element, and a plurality of cushion members. The suspension carrier includes a through hole and a plurality of first fixing portions beside the through hole. The top cover includes a plurality of second fixing portions. The globular element is disposed between the suspension carrier and the top cover. A portion of the globular element passes through the through hole. Each of the cushion members is correspondingly connected with the first fixing portion and the second fixing portion.

A shelving layout concept which allows selective configuration and reconfiguration of the orientation of certain shelving systems within the central portion of a store to create a PrimeZone area including an assembly of End Caps, Center Caps, Power Sets, Corner Boards, Hot Spots and Banner Boards, the combination of which provides a solution for enabling retailers to re-invigorate their Center Store, increase their vendor promotional revenue, and increase their in-store sales due to more favorable consumer response to greater promotional activity and the continuing change of product venues in key areas of the store layout. The concept also includes novel hardware which enables the reconfiguration of the shelving layout to accommodate vendors' desire to change display schemes.

The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having an increased slope, which means a smaller angular slope level, or a more acute inclination angle between the central vertical axis of the device and the surface upon which it rolls. The slope, or inclination angle of the present improved device is from 62 to 50, or less. As the inclinations angle can be more acute, the object supported on the rolling system, e.g. a luggage case, can be more sloped without having friction between the main ball involving structure and the ground.
