Description

  The present invention relates to a mounting device for a blower (circulation fan or ventilation fan) installed in a house.

  The blower in the house and the circulating wind thereby are essential equipment for promoting the growth of crops, improving the quality, or improving the efficiency after spraying chemicals, and are used in many houses. The blower is usually mounted via a mounting bracket (a mounting bracket, a frame, or a hanging bracket) on the beam, and the mounting bracket and a fastener (U bolt, bolt). Therefore, it has an up / down function (a depression angle adjusting function) in the wind discharge direction (blowing direction). However, it is considered that the mounting device (conventional mounting device) having the depression angle adjusting function is not sufficient to send the fan wind to every corner of the house and far away in the building direction. In addition, it is customary to remove the blower once and perform it during work such as spraying chemicals in the house, changing the vinyl film in the house, or removing the vinyl film in summer. For this purpose, it is not considered that the structure can be operated by one person in the removal and subsequent attachment.

  Since improvement of the conventional attachment device and an attachment device that can be attached / detached by one person is desired, it will be examined from the prior literature. For example, a fixing bracket for a ventilation fan described in Japanese Patent Application Laid-Open No. 2006-46818 is attached to a base (base) on a pipe (beam) of a house and supported on a mounting support (fixed support) provided on the base base. The fan can be rotated in 360 degrees steplessly by providing a structure that supports the support post (rotatable support) facing each other and supports the support post so that the fixed support post and the support post can be fixed and released. To do. However, the present invention is considered problematic because it does not include a depression angle adjusting mechanism. Also, I think that it is not enough to give the best wind to the crop, send it to every corner of the house, and send it far away in the ridge direction. Further, it is not possible to lift the blower alone and temporarily support it by inserting or hooking it into the fixing bracket.

JP 2006-46818 A
