Abstract

A step-stool has a flat top and four extendable legs so that it can be levelled on stairs or uneven ground. Each leg consists of a pair of telescoping tubes retained in a selected position by means of an intemal spring clip locating in holes in the outer tube. The stool may have additional step-up rails or bars and the top may be in the form of an open grid to allow plaster to fall through. A storage compartment may be provided under the top in the form of a sliding drawer or a tray, in which case the top pivots to allow access. A handle may provided in the top for carrying and the stool may also have a hand rail. The step-stool can be used with another to support an extendable scaffold board.

Description

[THE EXTENDABLE HOP-UP 1 [TECHNICAL FIELD] THE INVENTION RELATES TO A BENCH LIKE STOOL WITH EXTENDABLE LEGS.

[BACKGROUND] MOST TRADESMEN IN THE BUILDING TRADE HAVE DIFFICULTY REACHING UP TO HIGH PLACES.

PLASTERERS, PLASTER BOARD TACKERS, PAINTERS AND DECORATORS, ELECTRICIANS, PLUMBERS, DRY LINERS, BRICKLAYERS, CARPENTERS, FENC ERS,ETC.

THEY ALL HAVE TO REACH UP HIGH MOST OF THE TIME , MOST TRADESMEN USE STEP-LADDERS OR A HOP-UP OF SOME SORT, I.E. MILK CRATE OR A WOODEN HORSE AS SHOWN ON PAGE 4. WITH STEP-LADDERS THEY ARE CLUMSY AND AWKWARD, ESPECIALLY ON UNEVEN GROUND OR ON STAIRS.

[ESSENTIAL TECHNICAL FEATURES] THE EXTENDABLE HOP-UP HAS A FLAT TOP 1 AND FOUR EXTENDABLE LEGS 4.

EACH LEG CAN BE EXTENDED, SO WHEN YOU ARE WORKING ON AN UNEVEN GROUNG OR STAIRS ALL YOU HAVE TO DO IS ADJUST THE LEGS 4 TO THE APPROPRIATE LENGTH REQUIRED AS SHOWN ON PAGE 9.

[THE FLP TOP HOP-UP WITH TOOL TkAY] THE HOP-UP CAN BE MADE WITH A FLIP TOP I THAT WHEN OPENED REVEALS A TOOL TRAY 5 WHICH CAN CARRY ANY TRADESMAN'S TOOLS AND IF NECESSARY CAN BE TAKEN OUT OF THE HOP-UP.

SO EACH TRADESMAN HAS A TOOL BOX AND EXTENDABLE HOP-UP BUILT IN ONE.

[THE GRID TOP HOP-UP] FOR PLASTERERS THERE IS A GRID TOP HOP-UP WITH NO TOOL TRAY, SO WHEN PLASTERING THE PLASTER THAT FALLS FROM THE TRAIL ONTO THE TOP OF THE HOP-UP, WILL FALL THROUGH THE GRID AND NOT BUILD UP ON THE TOP WHICH COULD MAKE IT HEAVY. THIS HOP-UP ALSO HAS EXTENDABLE LEGS.

[THE HOP-'JP WITH DRAW] THIS HOP-UP HAS A BUILT IN DRAW 7 SO WHEN YOU ARE STANDING ON TOP OF THE HOP-UP THE DRAW 7 CAN BE PULLED OPEN TO REVEAL THE TOOLS, ALLOWING YOU TO SEE AND USE WHICHEVER TOOL YOU REQUIRE WITHOUT GETTING OFF THE HOP-UP AS SHOWN ON PAGE 3.

THIS HOP-UP ALSO HAS EXTENDABLE LEGS 4.

ALL HOP-UPS LISTED IN THESE PAGES HAVE STEP UP RAILS 3 AS SHOWN ON PAGE 1 NUMBER 3 WITH THESE STEPS-UP RAILS 3 ENABLES YOU TO STEPUP ONTO THE HOP-UP USING THE STEP-UP RAILS 3 RATHER THAN HAVING TO CLIMB OR JUMP ONTO THE HOP-UP.

WHEN YOU USE THE STEP-UP RAILS 3 AND CLIMB ON TO THE HOP-UP, IT WILL NOT TIP OR MOVE.

[HOUSEllOLD BOP-UP WITH EXTEDABLE LEGS ] THE HOP-UP FOR HOUSEHOLD USE IS SMALLER THAN THE INDUSTRIAL HOP-UP, AND HAS A FLIP TOP I AND TOOL TRAY 5 BUILT IN AND ALSO A HANDLE 8 WITH A RUBBER GRIP 9 FOR SAFETY REASONS AS SHOWN ON PAGES.

[HOP-UP WITH EXTENDABLE LEGS] THE HOP-UP CAN BE MADE OUT OF MOST MATERIALS SUCH AS, ALUMINUM, HARDENED PLASTIC, STEEL, UPVC, CARBON FIBRE, FIBRE GLASS, GRAPHITE.

THE LEGS CONSIST OF ONE TUBE INSIDE ANOTHER, WITH THE OUTER TUBE HAVING HOLES PUNCHED INTO IT, AND THE INNER TUBE HAVING THE SPRUNG BALL CLIPS AS SHOWN ON PAGE 10.

[HOP-UP ACCESSORIES] AT THIS MOMENT WE ARE WORKING ON NUMEROUS ACCESSORIES FOR THE HOP-UP. OF WHICH ONE IS THE EXTENDABLE SCAFFOLD BOARD, AS SEEN ON PAGE 8. THE EXTENDABLE SCAFFOLD BOARD 11 CONSISTS OF TWO SECTIONS, OF WHICH ONE SLIDES INTO THE OTHER AS SHOWN ON PAGE 8. IT ALSO HAS SPRUNG LOADED CLIPS 12 WHICH ATTACH BOTH SIDES OF THE HOP-UP AS SHOWN ON PAGE 8.

[EXAMPLES] A SPECIFIC EMBODIMENT OF THE INVENTION WILL BE DESCRIBED BY WAY OF EXAMPLE WITH REFERENCE TO THE ACCOMPANYING DRAWINGS IN WHICH PAGE 1 SHOWS THE HOP-UP WITH EXTENDABLE LEGS AND FLIP TOP AND STEP-UP RAILS PAGE 2 SHOWS THE HOP-UP WITH EXTENDABLE LEGS AND FLIP TOP AND TOOL BOX TRAY WITH STEP-UP BARS PAGE 3 SHOWS THE HOP-UP WITH THE EXTENDABLE LEGS AND FLAT TOP WITH DRAW.

PAGE 4 SHOWS THE HOP-UPS THAT ARE BEING USED ON SITE NOW PAGE 5 SHOWS THE HOUSEHOLD HOP-UP WHICH IS SMALLER AND HAS A HANDLE AND RUBBER GRIP.
