Abstract

A shoulder-supported pneumatic sweeping apparatus including a frame having attached to its upper portion a grip having a shoulder strap connected thereto, and formed at one end thereof with an air outlet port connected through a flexible pipe to an air ejecting pipe having an operating handle attached thereto. The frame is supported by the shoulder of the operator through the shoulder strap and prevented from moving unsteadily with one hand while the air ejecting pipe is operated with the other hand.

Claims

1. A shoulder-supported pneumatic sweeping apparatus comprising:

a frame;

a light weight engine mounted in said frame;

a fan mounted on an output shaft of said engine in said frame;

an outlet port formed in said frame for an air current produced by the rotation of said fan;

a grip having a throttle valve trigger and an engine stop switch located on an upper portion of said frame;

means isolating said grip from vibration imparted to said frame by operation of said engine;

means detachably securing said grip and said isolating means in said frame;

a shoulder strap connected to opposite ends of the upper portion of said grip;

an air ejecting pipe connected to said outlet port through a flexible pipe; and

an operating handle attached to said air ejecting pipe, said operating handle extending upwardly sidewards,

whereby said frame can be supported by the shoulder of the operator by means of said shoulder strap and a pneumatic sweeping operation can be performed while the operator holds the grip in one hand and the operating handle in the other hand.

2. A shoulder-supported pneumatic sweeping apparatus as claimed in claim 1, wherein said fan is a centrifugal fan.

3. A shoulder-supported pneumatic sweeping apparatus as defined in claims 1 or 2 comprising a cover detachably secured to said frame, said frame and said cover each having a hook provided thereon, and a strap with fastener members detachably engaged with said hooks whereby said cover is detachably secured to said frame.
