Abstract

PURPOSE:To obtain a transfer caster for a stepladder for the interior construction such as ceiling groundwork, etc. by axially supporting a self wheel between a pair of side plates installed in projection onto a supporting plate and installing a clamp onto the other side surface of the supporting plate. CONSTITUTION:Each caster 1 is installed at the lower edges of the two legs 3b and 3b on the side 1 out of the four legs of a stepladder through the divided clamp 2 in spread state and fastened by a nut 2d and a screw 2c. Then, the clamp 2 can be fixed through a rubber packing 4. With such constitution, the stepladder, etc. can be easily rolled and transferred by the wheel 1c of the caster.

) 4 wooden legs (3a) (3a) and (, 3b) (3b)
The casters (1) are fixed to the lower ends of the two wooden legs (3b) (3b) on one side using clamps (2). That is, as shown in the first figure, a rubber backing (4) is placed between the inner surfaces of the fixed half portion (2a) and rotating half portion (2b) of the clamp (2) and the outer surface of each leg (3b). By tightening the intervening locking nuts (2d), the positions for removing the caster (1) from the legs (3b) are defined reliably, and the fixed position of the caster (1) is determined by tightening the locking nuts (2d). As shown in Figure 2, the lower end of the clamp (2) should be about 5 mm from the lower end of the leg (3b) on three sides. When the stepladder (3) is set up as shown in the figure, the casters (1)
