Description

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

  The blower in the house and the circulating wind by the function of this blower are indispensable facilities for promoting the growth of crops, improving the quality, or improving the efficiency after spraying the chemical solution, 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.

  An improvement of the conventional mounting device, a mounting device that can be easily mounted and removed, and a mounting device that can freely adjust the rotational position (rotational position adjustment) by adjusting the depression angle and fixing the rotational position of the blower or releasing the fixing. Since it was sought after, it will be examined from the previous 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 ° steplessly by providing a structure that supports the support post (rotatable support) and supports the support post and the support post so that they can be fixed and released with the support fixture. To do. However, the present invention is considered problematic because it does not include a depression angle adjusting mechanism. In addition, I think that it is not enough to give the best wind to the crop, to send it to every corner of the house, and to send it far away in the ridge direction. Further, according to the present invention, it is not possible to lift the blower alone and temporarily support the fixing bracket by inserting or hooking it, and it is impossible, and it may be difficult to perform the installation work.

  There is a mounting device (a structure that can be mounted with the same mounting bracket) that allows the fan to be mounted on a beam, a column, or other mounting portion, for example, on top / hanging installation, vertical column installation, or other installation freely and easily. , Recently sought after. However, in the present situation including the prior art and the present invention, no appropriate mounting and installation can be found with respect to the mounting device that can freely and simply install the blower.
