Abstract

PURPOSE:To reduce the space in the rear of the body of a blower, by providing a stand for retractably supporting an extendable member for supporting the blower body oscillatably in the lateral direction so that the extending and retracting operation of the extendable member is synchronized with the lateral oscillation of the blower body. CONSTITUTION:One end of an extendable link 22 is pivotally supported to the outer peripheral section of an extendable cam member 21, and the other end of the extendable link 22 is pivotally supported by a cylinder section 13. The rotation of the extendable cam member 21 causes the pivotally supporting section of the extendable link 22 with respect to the extendable cam member 21 to move back and forth so that an extendable member 3 extends and retracts relative to the cylinder section 13. The extendable member 3 is extended and retracted relative to a stand in synchronism with the lateral oscillation of a blower body 2. Accordingly, the space for the lateral oscillation of the blower body may be ensured with the projecting amount of the blower body from the wall surface W being made minimum. The mechanism may be simplified by carrying out the lateral oscillation, and extending and retracting operation of the blower body with the use of an oscillating motor 16, and the movements of all sections may be easily synchronized.

swings left and right around the support shaft (9). The left and right oscillation is performed once in one rotation of the oscillation cam body αa. When the pivot part of the oscillating cam body tta+ of the oscillating unit 9 is located on the right or left side of the 1-second rotation center, the blower main body (2) faces forward. When it is located behind it, it faces to the right, and when it is located behind it, it faces to the left.

). A left and right swinging mechanism μs is formed at the rear of the electric kb machine. In this embodiment, the lateral swing mechanism μs is formed by a conventionally known gear mechanism driven by the electric motor. Said left and right swing mechanism l38
1 is not limited to being formed by a gear mechanism, but may be formed by a conventionally known oscillating motor. A swing cam body MY is formed on the output shaft 139) of the left and right swing mechanism. One end of a four-swing link l is pivotally supported on the outer peripheral portion of the swinging cam body (g), and the other end is pivotally supported on the telescopic body field. The above-mentioned stand (to) is attached to the wall surface (the base part to be attached)
□, a pillar part 9 formed with a fork at the tip protruding from the base part UΔ, and a neckpiece part pivoted to the fork part of the pillar part so as to be able to freely adjust the elevation angle. . The neck piece part is formed with a front opening (44a) for supporting the telescopic body ffl'Y in a freely retractable manner. The cylindrical portion (44a) is formed into a rectangular shape.

The Mfl implant is composed of a cylindrical portion (35a) with an open top and a lid portion (35b). The extensible body (7) is formed into a rectangular prism shape and is inserted into the cylindrical portion (44a), and is supported in an extensible manner by moving in and out back and forth. Even when the extensible body (to) expands and contracts, the cylindrical portion (44
a) A roller part (c) is formed on the inner side surface for smooth expansion and contraction.It should be noted that the roller part (c) may be formed on the inner surface of the cylindrical part (44a). The effects of this can be obtained. The front part of the lid part (35b) has an insertion hole through which the oscillation link (I) is inserted, and the swing link.

The state shown in FIG. 9 is when the main body view of the blower is facing forward, and the extensible body (to) is most contracted. When the main body of the blower starts swinging against the stone from this state, the connecting cam rotates to the left, pulling the first link Q5av and rotating the seesaw link ψυ to the right. When the seesaw link is rotated by the stone, the second link is pushed, and the connecting pin is pushed into the center of the ring. Although the connecting pinion pushes the middle ICC, it does not create a rotational force, but instead pushes back the second link Q, and the connecting pinion (B) engages the guide rack Q and the connecting rack (to) By being connected only to the elastic body, the elastic body (to) is pushed forward by the above-mentioned push-back force. By moving the telescopic body forward, the guide rack is moved forward, and the connecting pinion is rotated to the right.

A contracting and contracting body (to) stretches. From this state, when the main body of the blower (to) moves to the left, the connecting cam (2) begins to rotate to the right, and the first link (@) is pushed, causing the seesaw link 151 to rotate to the left. and the second link Q is pulled. When the second link μs is pulled, the telescopic body (to) is pulled in an odd direction, and is housed in the cylindrical portion (44a), and at the same time, the connection is completed by the guide rack. The pinion rotates counterclockwise. By rotating the connected pinion to the left, the luck, 1
The roller moves along the store rack φ, moves the telescopic body (to) backward and contracts it, and when the main body of the blower (to) faces forward, the telescopic body (c) contracts the most. When the main body of the blower further swings to the left, it moves from the state shown by the two-dot chain line in Fig. 10 to the state shown by the two-dot chain line in Fig. 11, and then swings to the right as described above. The stretchable body (to) extends in the same way as when performing the above.

By making the extensible body (to) expand and contract with respect to the stand (e) in synchronization with the left and right oscillation of the main body view of the blower.
