Claims. (Cl. 248-122) This invention relates to .an adjustable .support means, and more particularly to a mobile adjustable support for maintaining a fan at various levels and positions above the floor.

The present invention represents an improvement in mobile adjustable supports for fans, and permits support of a fan at .and from floor level to various .fixed levels thereabove. Among the more important advantages realized by the invention is the fact that a very low center of gravity may be attained to avoid tipping during use and in moving, and further, that a very compact assemblage is provided, thus minimizing storage and packaging In addition, the adjustable support of the present invention is simple in structure, and provides positional adjustment of the fan in a convenient and easy 'support that afiords convenient and easy fan adjustment at various heights and positions relative to the floor.

These and further objects and features of the invention will become more apparent from the following description and accompanying drawings wherein:

Fig. 1 is an illustration of a mobile adjustable fan support representing an embodiment of the invention, and showing a fan being positionally supported at floor level;

Fig. 2 to 4 inclusive are fragmentary views of the same showing various levels of fan adjustment;

Fig. 5 is a plan view of the assemblage illustrated in Fig. 1;

Fig. 6 is a section view as seen from line 6-6 in Fig. 5;

Fig. 7 is an end view of the assemblage illustrated in Fig. 1;

Fig. 8 is a view as seen from line 8-8 in Fig. 1;

Fig. 9 is a view as seen from line 9-9 in Fig. 2;

Fig. 10 is a view as seen from line 10-10 in Fig. 3;

Fig. 11 is a view as seen from line 11-11 in Fig. 4; and

Fig. 12 is an enlarged view as seen from line 12-12 in Fig. 1.

Referring now to the drawings the numeral 16 identifies a mobile adjustable support means representative of an embodiment of the invention, which includes a tubular frame member 17 supported for movement upon a plurality of casters 18, and a pair of arms or link members 19 the upper end of each being pivotally supported upon an integral pin 21 which projects through a longitudinal hole 20 formed in a plate or bracket 22, the

Federated Dec. d, 1960 'is formed. The bracket 22 has a curved peripheral portion 39 at one end with an abutment 31 formed at the lower extremity of the curved portion 30, and a downwardly extending notch 32 formed at the upper extremity of the curved portion. The curved portion 30, as well as the abutment 31 and notch 32, serve as a camming means to guide and maintain an arm 19 in two vertical positions of adjustment removed, as will be further explained.

Each arm 19 has an integral finger or'pin 34projecting from the side and adapted to ride upon or against the curved peripheral portion 30 and engage the abutment 31 when the arm 19 is in down-position (Figs. 8 and 9) and to engage or be received by the slot 32 when the arm is in up-position (Figs. 10 and 11). It will be seen that longitudinal shifting of the arm 19 for engagement or release from the slot 32, is permitted by provision of the longitudinal slot 20.

Toward the other end of .each arm 19 'is formed an elongated S-shaped slot 36 which is adapted to receive the shaft of a tightening knob 37. Each knob '37 is adapted to screw into the side of a fan 38, which is generally rectangular in shape and of such width as to be supportable between the arms 19 (Fig. 1). By tightening the knobs 37 it will be seen that the fan 38 may be fixedly secured and supported by the arms 19. The

fan 38 has a handle 39 on the upper surface for convenient lifting of the fan, and a plurality of legs 41 on the lower surface for engagement with the floor when the fan is in lowermost position (Fig. 8).

From the foregoing it will be seen that fan support 16 will allow at least four normal positions of adjustment relative to the floor or supporting surface, all as illustrated in Figs. 8 to 11 inclusive. In the Fig. 8 position the legs 41 are in engagement with the floor; in Fig. 9 the fan is supported with the arms 19 in down-position and the shafts of tightening knobs 37 engaging the upper extremity of the S-shaped slots 36; in Fig. 10 the fan is supported with the arms 19 in up-position, i.e., 180 removed from the Fig. 9 position, and the shafts of tightening knobs 37 engaging the lower extremity of the S-shaped slots 36; and, in Fig. 11 with the arms 19 in up-position and the shafts of tightening knobs 37 engaging the upper extremity of the S-shaped slots 36. It will be obvious that in addition to the above described positions, the fan may be supported with the tightening knobs 37 clamping the fan at any position along the length of the slots 36. Furthermore, while the fan has been shown as positioned so as to provide air movement generally parallel with the floor, the fan may be rotatably supported in any angular position relative to the floor, such as to provide air movement at a right angle thereto as in the case of a hassock fan.

Finally, while the adjustable supporting means 16 of the invention has been illustrated as applied for the support of a fan, it will be apparent that it may be used as effectively for the support of other devices, such as radiant heaters, flood lights, etc.

It will be seen that a mobile adjustable fan supporting means incorporating the principles of the invention, will permit the support of a fan at various heights and positions relative to the floor, is easily moved about, provides a low center of gravity when the fan is in lowermost position, and is very compact and convenient to use.

The foregoing description has been given in detail without thought of limitation since the inventive principles involved are capable of assuming other physical embodiments without departing from the spirit of the invention and the scope of the appended claims.
