Fan

Abstract

A fan for creating a microclimate at any point in the desk area of a user. Positioned under a desk top, the fan comprises a fan and a device for moving the fan beyond the edge of the desk top, enabling adjustment of the spatial position of the fan. The technical result consists of reducing the distance between the fan and the user, enabling the fan to alter the microclimate in the desk area, at any point in the space immediately around the user, without disturbing the user.

1 . A fan for creating a microclimate in the desk area of a user, characterized in that the fan is positioned under a desk top and equipped with a device for moving the fan beyond the edge of the desk top, enabling adjustment of the spatial position of the fan. 
     
     
         2 . The fan of  claim 1 , characterized in that the device for moving the fan beyond the edge of the desk top is made in the form of a lever rotatable in the vertical plane about the horizontal axis, the lever being connected to the fan by the rotation axis of the fan perpendicular to the horizontal axis. 
     
     
         3 . The fan of  claim 2 , characterized in that the device is equipped with a clamp for one extreme position of the fan provided in the form of a spring latch. 
     
     
         4 . The fan of  claim 2 , characterized in that the device is equipped with clamps in the form of a friction washer, two anti-friction washers and a compression spring therebetween for any positions of the fan about the horizontal axis, and in the form of a friction washer, a threaded axis, a nut and a lock nut about the rotation axis perpendicular to the horizontal axis. 
     
     
         5 . The fan of  claim 1 , characterized in that the device for moving the fan beyond the edge of the desk top is made in the form of a cylindrical slider capable of a reciprocating movement and a rotation about its axis, the slider being located in the guide and connected to the fan by the rotation axis perpendicular to the axis of the cylindrical slider. 
     
     
         6 . The fan of  claim 5 , characterized in that the device is provided without retaining fan positions. 
     
     
         7 . The fan of  claim 5 , characterized in that the device is equipped with clamps in the form of a friction radial stop, a screw and a lock nut for any positions of the fan during the reciprocating movement and rotation about the axis of the cylindrical slider, and in the form of a friction washer, two anti-friction washers and a compression spring therebetween about the rotation axis perpendicular to the axis of the cylindrical slider. 
     
     
         8 . The fan of  claim 1 , characterized in that the device for moving the fan beyond the edge of the desk top is made in the form of a bar rotatable in the horizontal plane about the vertical axis of the bar, the bar being connected to the fan holder by the vertical axis of the holder connected to the fan by the horizontal rotation axis of the fan. 
     
     
         9 . The fan of  claim 8 , characterized in that the device is provided without retaining fan positions. 
     
     
         10 . The fan of  claim 8 , characterized in that the device is provided with clamps in the form of friction washers, nuts and lock nuts for any positions of the fan about the vertical axis of the bar and the vertical axis of the holder, and in the form of an additional fan casing fixedly connected with two semi-axes located on both sides about the horizontal rotation axis of the fan in the holder, the semi-axes being provided with friction washers, nuts and lock nuts.
