Claims. (01. 248194) This invention relates to an improved stand or pedestal for supporting apparatus of various kind, such as a hair dryer of the type used in beauty shops.

An important object of the invention is to pro vide an improved pedestal of this character, made up of parts which may be manufactured and assembled at relatively low cost.

More specifically it is an object of the invention to provide a supporting stand having a base and a hollow column, essentially consisting of an assembly of identical, complementary parts each of which includes a portion of the base and a longitudinal sectional portion of the column.

Yet another object is directed to improved provision for rigidly uniting the sections to produce a sturdy and durable base stand.

Another object is to provide a stand constructed in the described manner and which includes an extensible tube or stem to carry and provide for height adjustment of the supported apparatus or appliance.

Other objects are directed to provisions, in a stand of this character, of a spring for counterbalancing the weight of the supported apparatus to facilitate the height adjustment thereof, of means for positioning the spring and the stem, and of frictional means of simple design for holding the stem and apparatus in adjusted position.

These and other objects and advantages will appear from the following description and the accompanying drawing wherein:

Fig. 1 is an elevational View of a hair dryer embodying the pedestal of my invention;

Fig. 2 is a perspective view showing the inner side construction of one of the leg sections of the pedestal;

Fig. 3 is a sectional elevation taken at line 3--3 of Fig. 7, and

' Figs. 4, 5, 6 and 7 are transverse sectional views of the supporting column of the pedestal, taken respectively at lines 44, 5-5, 6-45 and 'l! of Fi 3.

Referring now by numerals of reference to the drawing, the pedestal of my invention comprises a tripod base structure having a hollow tapered column 10, feet I I, and a telescopically adjustable tubular stem l2 which extends into the column and carries at its upper end the apparatus or appliance [3, which, in the present example, is represented by a hair dryer of the type generally employed in beauty shops. The base structure is essentially composed of three identical, preferably die-cast sections of the character illustrated in Fig. 2, each having one integral and complete foot I4 which projects at an appropriate angle from the lower end of the sectional portion [5 of the column. The wall constituting portion I5 is arcuate in cross-section and'extends through an angle of 120 degrees about the column axis.- When the sections are assembled as shown in Figs. 3 and 7 the dividing or parting planes symmetrically trisect the column longitudinally, and bisect the angles formed between the feet IA. Each of the column sections is provided with an integral longitudinal rib or fin I6 which pro.- jects radially inwardly from the wall of the section and lies in the longitudinal median plane of the foot portion M. The vertically extending inner'edge of the web is parallel with the column axis and in spaced relation thereto. At its lower end the rib I6 projects a short distance below and beyond the wall of the column section andmerges with a rib [8, in the same plane thereof, which projects downwardly from the under surface of the top wall I 1 of the foot. As will be understood the rib l8 serves to reinforce the foot and particularly the junction of the foot and column section. The rib [6 serves to strengthen the column and has certain additional functions which will be hereinafter explained. The rib I6 terminates upwardly at a horizontal sector shaped flange [9 which is spaced below the upper extremity of the column section, the flange l9 having an armate recess 20 to accommodate the stem [2. The upper end of the column is turned inwardly to provide a terminal flange 2| which is recessed as at 22, likewise to accommodate the stem l2. It will be observed that when the parts are assembled a compartment 23 is formed between the flange portions l9 and 2|, and this compartment serves to receive and position frictional means, indicated generally at 24, for gripping the stern and retaining the apparatus in fixed position after the same has been adjusted to the desired height. Such means will subsequently be described in detail;

Reverting now to the foot structure l1, itwill appear that this part is channel-shaped in crosssection and includes the top wall I! which has an outwardly salient reinforcing rib 25 thatterminates near the outer end of the foot at an 3 r example there. being four of these which are disposed in spaced relation along the column. These rings, designated 3|, 32, 33 and 34, are'of graded diameter so as to conform to the taper of the column and each ring seats in an annular groove appropriately formed in the column wall. The sections are further secured together at the base of the column by means of a disc or tieplate 35 whichis secured'by screws. 36 to. internally threaded bosses LSI integralrwith the ribs I6. This tie-plate positively maintains the column sections in edge abutting and contiguous 7 relation and prevents dislocation of the parts, such as might otherwise result from forcesiacting laterally on the legs. The tie plate 35.,also pro,-.. vides a bottom support for a spring38whf0hiri turn supports and balances theiwei'ghtiof the;stem' l2 and apparatus carried thereby.

The stem l2 passes through the closely-fitting 7 circulariopenings formedin the composite flange portionsz'll-andifl, and-ithe lower end :of the stem i's upsetor otherwise enlarged toproduce thereon a b ead or en'd flange w th'at bears upon the upper the {flange 39 and the marginal' portions of the ribs tt extend into these recessesand form guide me mbers for the lower -end offithe stem, also preventing thestem irom turning=with'respect tozthe base structure. The notches or zrecessesuoihave predetermined circumferential locations, such that the pedestal and s'tefn 'will' 'h'ave a definite and hired angulargrelationship which is ipreferably such thatthe' center :of gravity :of the-ap:
