選択傾斜位置に保持する。 The electric fan according to the present invention can be placed on table 2,
It has a main support 1 in the form of a pedestal for mounting on a wall 3, and a mounting base 4 for mounting a fan head 5 comprising fan blades 7 and a motor for moving these blades. The fan head 7 is surrounded by a protective wire grid 8. The mount 4 is pivotally connected to the main support 1. This pivot joint consists of two side parts 9, 10 projecting from the main support 1 and a mounting base 4.
This is done between the two side parts 11 and 12 that protrude from the top. The side parts 11 and 12 from the mount 4 are also pivotally connected to the side parts 9 and 10 from the pedestal (main support) 1 by bolts 13, so that the mount 4 and the fan head provided thereon are attached to the main support 1. The angle can be adjusted to a tilted position. In order to selectively hold the mount 4 and the fan head 5 anywhere within such a range of inclined positions, the main support has an arcuate ratchet 14 fixed to the side surface 11 of the mount 4 and a protrusion 16. Retaining means are provided comprising a pawl 15 in the form of a leaf spring for attachment to the body 1. The ratchet 14 cooperates with the protrusion 16 of the leaf spring 15 to hold the mount 4 and the fan head 5 attached thereto in a selected tilted position.

は条溝の一方の端部に位置させる。 The electric fan can be used as a tabletop or wall-mounted type. In either mode of use, the center position of the combined gravity of the mounting base 4 and the fan head 5 is displaced so that the holding means 14, 15, 16 can no longer hold the fan head in the desired position. A latching means is provided to securely hold the fan head even in such a state. The latching means comprises a pivotable latching member 17 comprising a cylindrical first part 18 and a second cylindrical part 19 connected to each other by a third part 20. The first and second cylindrical portions are arranged such that their longitudinal axes are parallel to each other.
Provided at both ends of the section. The cylindrical first part 18 is supported on the side face 12 of the mount 4 and is freely pivotable about its longitudinal axis. The cylindrical second portion 19 can slide within a slot-like groove 21 formed in a flat plate 22 attached to the inside of the side surface 10 of the main support 1. The groove 21 is curved and has two recesses 23 and 24 in its side wall. First recess 23
is located approximately in the middle of the groove 21, and the second recess 24
is located at one end of the groove.

る。 The operation of the holding means 14, 15, 16 and the latching means 17, 21 is as follows. When the fan is placed on a table, the inclination of the fan head and therefore the direction of the airflow generated by the fan blades can be adjusted as desired by rotating the fan head upwards or downwards. At this time, the protrusion 16 of the pawl 15 cooperates with the ratchet 14 to hold the mounting base 4 and fan head 5 in the desired position.

により行う。 When the fan head 5 is held at a predetermined downwardly inclined position as shown in FIG.
The position of the center of combined gravity (center of gravity) 25 between the mounting base 4 and the main support 1 is on the right side of the perpendicular line 26 passing through the pivot axis 27 of the connector between the mounting base 4 and the main support 1 (as viewed in the drawing)
The holding means 14, 15, 16 are no longer able to hold the fan head 5 because it has moved far away. Therefore, it is necessary to support and hold the fan head so that it does not move further downward. This holding action is achieved by abutting the second portion 19 of the latching member 17 against the upper end 28 of the groove 21, as shown in FIG.

The portion 19 is formed into a recess 23 approximately in the middle of the groove 21.
to maintain the fan head in this extreme upwardly tilted position.

This position is inherently inconvenient for the stability of the fan head. In such a case, the fan head can be swiveled further upwards to move the second part 19 of the latching member 17 below the groove 21 so that, under the influence of gravity, the second part 19 is placed at the lower end of the groove 21. The second recess 24 is pivotally engaged. In this way, the second portion 19 of the latching member will fit into the recess 2.
4, the fan head 5 is locked against downward movement.
