Abstract
The present general inventive concept teaches a shoring apparatus with roller bearing to facilitate ease of use and inhibit undue wear on the apparatus. The apparatus is expandable and retractable and is releasably secured via a tightening assembly. In some embodiments, the tightening assembly includes a nut, at least one flat washer, a roller bearing, at least two split rings, and a rotator. The tightening assembly—featuring the roller bearing—serves to decrease friction, increase safety, and enhance both ease of positioning and ease of stabilization with respect to the shoring apparatus.
Claims6
A shoring apparatus with roller bearing, said shoring apparatus comprised of:
- a base, said base being of an overall cylindrical rod shape, said base further having defined thereon an upper terminal end, a lower terminal end, an outer surface, an inner surface, and a void space within for receiving a core;
- a core, said core being of an overall cylindrical rod shape, said core further having defined thereon an upper terminal end, a lower terminal end, and an outer surface, said outer surface being of such dimension so as to be releasably secured within said void space to said inner surface of said base;
- and
- a tightening assembly for restricting movement of said core relative to said inner surface of said base and within said void space of said base, said tightening assembly comprising at least one nut, at least one flat washer, at least two split rings, at least one roller bearing, and at least one rotator, said rotator being defined to have an upper end, a midsection and a lower end.
The shoring apparatus as in any of the preceding claims, in which said lower terminal end of said base has attached thereon a base plate.
