A handrail lock member is housed therein, and at the lower end of the lock member, an engagement projection is provided which protrudes outward from an opening formed in the front wall of the handrail leg, and a handrail leg is provided at the upper end of the lock member. A projection for engaging and disengaging protruding outward from an opening formed in a rear wall of the handrail portion is provided at an intermediate portion of the height of the lock member, and a fulcrum projection for abutting against the inner surface of the front wall of the handrail leg. The lower end of the lock member is pressed against the inner surface of the front wall of the handrail leg by the spring force of the spring, and the handrail leg is attached to a cylindrical handrail receiver provided on the workbench side. As it is fitted from above, it protrudes outward from the front wall opening of the handrail leg. The leading end of the engaging projection at the lower end of the locking member is engaged with the handrail receiver, and is used for releasing the engagement that projects outward from the rear wall opening of the handrail leg when the handrail is removed. When the convex portion is pushed into the leg side, the lock member swings around the fulcrum projection as a fulcrum, so that the tip of the engaging convex portion of the lock member is disengaged from the handrail receiver. It is characterized by having.

It is only necessary to fit the lower end of the leg of the handrail into the handrail receiver from above. As a result, the distal end of the engaging projection at the lower end of the lock member projecting outward from the front wall opening of the handrail leg is further projected outward from the front wall opening of the cylindrical handrail receiver. The distal end of the engaging projection is engaged with the front wall of the cylindrical handrail receiver, and the handrail leg is locked when fitted into the cylindrical handrail receiver.

る。According to the handrail lock device of the present invention,
To attach each leg (8b) of the substantially inverted U-shaped handrail (8) to a cylindrical handrail receiver (20) provided on the workbench body (1) side, as shown in FIG. It is only necessary to fit the lower end of the leg (8b) of (8) into the handrail receiver (20) from above. This allows
A guide surface portion (11a) having an arc-shaped cross section of an engagement projection (11) of a lower end (10a) of a lock member (10) projecting outward from a front wall opening (14) of a handrail leg (8b). ) Is cylindrical handrail holder (20)
Is pressed against the front wall (20a), and the engaging projection (11) is once pushed into the inside of the handrail leg (8b) against the elastic force of the coil spring (18). At this time, the lock member (10) swings around the intermediate fulcrum projection (13) as a fulcrum, and furthermore, engages with the engagement projection (1).
When 1) reaches the front wall opening (21) of the cylindrical handrail receiver (20), it is made to protrude further outward from this opening (21). Therefore, in this protruding state, as shown in FIG.
The upper end of the engaging projection (11) is the front wall (20a) of the cylindrical handrail receiver (20).
Cylindrical handrail receiver that is engaged with the upper edge of the opening (21)
The handrail leg (8b) is locked in the state of being fitted into (20).

である。When removing the handrail (8), use the handrail.
It is only necessary to push the engagement release projection (12) projecting outward from the rear wall opening (15) of the leg (8b) of (8) into the inside of the leg (8b). As a result, as shown in FIG. 4B, the lock member (10) swings around the fulcrum projection (13) in the middle of the lock member (10), and the engagement protrusion (11) of the lock member (10) is rotated. The leading end enters the handrail receiver (20) through the front wall opening (21) of the cylindrical handrail receiver (20), and the handrail leg (8b) is unlocked.

摺受け(20)との連結の場合では、ロック装置の作用の説
明は、上記の場合と前後逆向きとなる。In the above description, the lock member (10) at the lower end of the front leg (8b) of the right scaffolding handrail (8B) and the handrail receiver (20) at the upper end of the front support (3) have the structure of a handrail lock device. The right leg scaffolding handrail (8B) has the opposite rear side
(8b) In the case of connection between the lock member (10) at the lower end and the handrail support (20) at the upper end of the rear support (4), the operation of the lock device is reversed in the above-described case.

場板(2) と後部支柱(4) とがほぼ直線状になり、作業台
本体(1) を折り畳むことができる(図7参照)。When the workbench body (1) is folded, first, the upper reinforcing member (7) is folded in an inverted V-shape in the middle thereof, and the rear edge portion and the lower reinforcing member of the scaffold plate (2) are reinforced. Lumber
When the lower end of (6) is brought closer to the front support (3), the scaffold plate (2) and the rear support (4) become almost straight, and the workbench body (1) can be folded. (See FIG. 7).
【0037】ここで、足場板(2) の前縁部と前部支柱
