United States Patent 3,127.,548 ADilUdTABLE FAN SUPPQRT STAND James il. McLean, Milford, Conn, assignor to General Electric @ompany, a corporation of New York Filed Sept. 13, 1961, der. No. 137,798 2 Claims. (til. 24-8-43) The present invention relates to an air circulating fan construction and more particularly to an adjustable fan and stand arrangement.
It has con desirable in certain air circulating fans to provide mobile fan stands that will facilitate moving the fans from room to room, dependent only upon where an individual user would desire that the fan be located. Additionally, it has been desirable to have such fans provide a vertically adjustable feature so as to more readily correspond with various operating heights that may be dictated for example by the varying heights of Window openin s. Also, the need arises to have a fan casing supported by such a mobile fan stand adapted to pivot or tilt about a horizontal axis so as to vary the direction of air flow developed by such an air circulating fan. However, the vertical adjustment of the fan casing with respect to the fan stand has not in the past incorporated a suitable guide with such fan stands to assist in locating the fan casing accurately and rapidly with a minimum of effort on the part of the individual user.
Accordingly, it is an object of the present invention to provide a new and improved fan stand to retain a fan casing therein.
It is likewise an object of the present invention to provide a new and improved fan stand that is mobile.
Another object of the present invention is to provide a new and improved fan stand that will permit vertical adjustment of a fan casing.
Yet another object of the present invention is to provide a new and improved fan stand which will permit vertical and pivotal adjustment of a fan casing.
Briefly stated, and in accordance with the present invention, a fan assembly is provided having a fan casing with suitable outwardly extending clamping means defining a pivotal axis through the casing and adapted to engage a pair of opposed elongated plates having suitable longitudinal slots therein with a plurality of spaced lateral notches intersecting each individual slot. A pair of spaced upwardly extending legs are provided and have the elongated plates mounted thereon to form a stand and base assembly.
While the specification concludes with claims particularly pointing out and distinctly claiming this subject matter, which may be regarded as the invention, the organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings, in which:
FIG. 1 is a front view of a fan assembly in accordance with the present invention;
FIG. 2 is a side view of the fan assembly shown by FIG. 1; and
FIG. 3 is a top view of the fan assembly shown by FIG. 1.
Referring to the drawings, and particularly to FIG. 1, the fan assembly of the present invention is shown therein and comprises a base assembly having a generally U- Shaped lower front tube 1 in tandem with and spaced from a lower rear frame 2 that is also suitably U-shaped and adapted to receive spaced rollers 3 and 4 such as shown thereon. A first upper frame 5 is formed to define a generally U-shaped member having deformed legs terminating in sockets 5a and 5b to receive respectively one end of the lower front tube 1 and one end of the lower rear frame 2. A second upper frame member 7 is correspondingly formed and adapted to receive the remaining end of the lower front tube and the remaining end of the lower rear frame in the sockets 7a and 7b of the second upper frame member 7. The upwardly extending vertical legs defined by the union of the first upper frame member 5 and the second upper frame member 7 with the lower front tube 1 and the lower rear frame 2, are parallel to each other and spaced from each other and retained more securely in this position by means of a suitable cross member A first elongated plate 9 is fixed to and bridges the space between the legs of the first upper frame member 5' and in conjunction with a similar second elongated plate 1h fixed to the second upper frame member '7 forms the arrangement of the invention that provides for the vertical and pivotal adjustment of the fan assembly.
A portable fan casing 13 is provided and received between the upwardly extending vertical legs of the base assembly. The fan casing 13 has a motor driven fan 14 therein which forms no part of the present invention but is of the type generally found in air circulating devices. A first stud member 15 and a second stud member 16 define support surfaces and extend outwardly from opposed walls of the fan casing 13 to engage and pass through the respective first plate member 9 and the second plate member if). The stud members 15 and 16 receive a threaded knob 17 and 18 respectively, which form suitable clamping means.
Referring now to Pl. 2, a side view of the fan assembly shown by FIG. 1 is presented wherein the elongated plate ill is clearly shown. The generally U-shaped second upper frame 7 is shown suitably deformed and terminating in sockets 7a and 7b to receive the respective ends of the lower front tube l and the lower rear frame 2. Cross member 8 includes two generally parallel side arms 20 and uniquely serves as a brace between members 7a, 7b, 5a and 5b. The elongated plate 19 fixed to the second upper frame member 7 bridges the area between the U and leaves only the bight of the U open to serve as one handle 22 when the particular fan assembly being described is moved from one location to another. Such movement may be accomplished by tilting the fan assembly about the horizontal pivotal axis defined by the rollers 5 and 4 so that the lower front tube 1 is elevated from a support surface. The fan assembly may then be moved to a desired location where it is again pivoted forwardly about the axis defined by the rollers until the lower front tube again engages the support surface and restrains further movement of the fan assembly.
The elongated plate ltl has a longitudinal slot 24 there in adapted to receive, with a slight tolerance therebetween, the outwardly extending stud 16 from the fan casing 13. A plurality of spaced notches such as shown at 25 are further provided that intersect the longitudinal slot 24. Elongated plate 9 is similar to plate ill and has a longitudinal slot such as slot 24 therein with similarly spaced notches such as the notch 25 of plate id. The notches in both plates 9 and it), such as the notch 25 of plate 19, intersect the longitudinal slot 24 laterally to provide suitable retaining means for the stud members 15 and 16 when the stud members are moved from the longitudinal slot 24 into the desired notches of the elongated plates 9 and ill.
FIG. 3 more clearly shows by a top view of the fan assembly the base assembly developed by the respective lower front tube 1 and lower rear frame 2 in cooperation with the first upper frame 5 and the second upper frame '7. The base assembly with the upwardly extending legs thus formed provides, when reinforced by the unique cross member 8, the light weight yet substantially rigid support for the fan casing 13 incorporating a degree of moenemas as? bility as evidenced by the suitable rollers 3 and 4 provided on the lower rear irame member 2.
In operation, the portable fan casing 13 is positioned between the first upper frame member 5 and the second upper frame member '7 so that the outwardly extending stud members 15 and 16 engage and pass through the longitudinal slots of the elongated plates 9 and it such as the slot 24 of plate it). The clamping knobs 1'7 and 18 are then threaded upon the stud members to restrain pivotal movement of the fan casing 13 about the pivotal axis defined by the outwardly extending opposed stud members 15 and 16. Generally, vertical adjustment of the fan casing 13 is provided by the longitudinal slots such as slot 24 so that when the clamping knobs l7 and 13 are released, the stud members 15 and lid of the fan casing may be raised or lowered to position the fan casing at a desired height above the base assembly and in a predetermined relationship thereto. In the present form of the fan assembly being described, the predetermined relationship of the pivotal axis would be that of a horizontal position which is parallel to the surface supporting the base assembly. When a desired vertical height of the fan casing 13 is achieved, the fan casing is displaced from the longitudinal slots into selected ones of the adjacent lateral notches and the clamping knobs 17 and 18 are again tightened to secure the fan casing at the desired height. However, the primary support is now provided by the respective notches receiving the stud members 15 and 16 rather than depending entirely upon a friction clamp means engaging only the elongated plates 9 and lil. Rapid alignment with regard to the base assembly is assured since the spaced lateral notches in the individual elongated plates define equal steps that are in alignment with each other. A lateral or pivotal axis is thus defined which has a predetermined relationship to the base assembly. By means of the clamping knobs 17 and 18, the fan casing 13 may be tilted about the pivotal axis defined by the outwardly extending stud members 15 and 16 to any desired angle to direct the air flow developed by the motor driven fan 14. The clamping knobs 17 and 18 restrain the fan casing at the desired tilt.
. As will be evidenced from the foregoing description, certain aspects of the invention are not limited to the particular details of the construction illustrated, and it is contemplated that other modifications and applications will occur to those skilled in tne art. It is, therefore, intended that the appended claims shall cover such modifications and applications that do not depart from the true spirit and scope of the invention.
