Westman, Arcadia, Calif. (3723 Queen Ave. N., Minneapolis, Minn.) Filed Feb. 1, 1963, Ser. No. 255,512 18 [lit-aims. (ill. 98-11.)

This invention relates to improvements in furniture sets and more particularly to canopied outdoor furniture, for example, wherein a power ventilator is incorporated into the canopy of the furniture set.

Umbrella or canopy covered tables of the Parisian sidewalk-cafe type, for example, for use out-of-doors have been known for many years. Such tables, however, usually provide only a central stanchion extending verticaliy centrally of the table to support a canopy or umbreila which provides shade and protection from precipitation to persons seated at the table.

The conventional canopied table provides only sun or rain shielding to persons seated around the table. Accordingly, the conventional canopy traps-air within its confines. Such air is heated through the canopy by solar radiation with the result that it is often warmer under such a canopy than if no canopy were provided, particularly where a breeze may be blowing. The conventional canopy also may prevent persons seated around the table from being cooled by a breeze blowing in the general vicinity of the table. These particular aspects of conventional canopy tables discourage use of such tables and detract from the utility thereof.

The present invention incorporates a fan or blower into a canopy for an article of furniture, such as a patio table, and provides means for directing the air currents created on operation of such fan in predetermined or variable directions for the benefit of persons seated at, or proximate to the article of furniture. Operation of the fan, by means provided by the present invention prevents the creation of pockets of stagnant air under the canopy and assures that persons seated around the table are kept comfortable and sociable. The benefits or" conventional canopies are retained.

Climatic elements such as high humidity in the atmosphere, high ambient temperatures, ordors, stagnant air, hordes of insects, all of which factors grossly affect the etficiency, performance, sociability, psychological orientation and disposition, health, and comfort of the human species in the conduct of its ati airs, are in no way treated, alleviated, or modified in any of the furniture heretofore devised.

As a result, the fully utility potential, value desirability, functionability, utilization efficiency (load factor), and novelty of such furniture articles has scarcely been realized.

Generally speaking, the present invention provides a power ventilated patio-type table unit. The unit is comprised basically of a table and canopy means for the table. Air moving means are secured to the canopy and means for selectively operating the air moving means are also prov led. The invention further includes means for so ying air to the air moving means and means coopeting with the air moving means for directing air discharged from the air moving means from the canopy means. Also, means are connected to the canopy teams for supporting the canopy means over the table or other article of furniture over which the canopy is disposed.

The canopy means referred to above comprises a canopy member preferably symmetrical about an axis and defining a shell which is concave downwardly. A rotatable fan is disposed adjacent the lower surface of the canopy member. The canopy member defines air passage means therethrough from its convex side to above the fan.

The above mentioned and other features of the invention are more fully set forth in the following detailed description of the invention taken in conjunction with the accompanying drawings wherein:

The invention is described herein in conjunction with a table, but it should be understood that the ventilated canopy may be used with any form of outdoor type furniture such as a deck chair, settee chaise lounge, or picnic-type table. The ventilated canopy of the present invention also finds utility in use with a childs sandbox or similar play area; a parent may leave a child in such a play area with the knowledge that the child is safe and comfortable and will not be overly exposed to solar radiation.

Referring initially to FIG. 1, a table having a top 1, supported by spaced apart legs 2 braced by a circumferential bracket 13, is provided in combination with a chair 12. A vertical, hollow, tubular stanchion 3 extends upwardly centrally of the table and supports a sun or weather-shade canopy comprised of a lower part 4 and an upper part 5. The pair of canopy parts are referred to hereinafter as the canopy. The canopy is a substantially shell-like, downwardly concave member preferably symmetrical about the vertical axis of the stanchion. The canopy has a concave downwardly lower surface and a convex upper surface. The upper canopy member is secured relative to the lower canopy member by a plurality of support brackets 19 (see FIG. 2) while the lower canopy member is supported to the stanchion by a plurality or radial brackets 21 extending inwardly from the lower member to a clamp 14 engaged peripherally of the stanchion. The lower end of the stanchion is mechanically connected, as by a flanged sleeve 9, to a receptacle box fastened to the upper side of a weatherproof battery protective housing 7 which receives a self-contained mobile energy source, such as a storage battery 22, and which supports the entire weight of the stanchion and the associated canopy. Electrical power from a central station is supplied to the canopy unit by an extension cord engageable with a receptacle 3 mounted in the receptacle box. The receptacle is connected by appropriate circuitry, as illustrated in FIGS. 10, 11, and 12, to a fan motor 16 regulated by an on-off switch 6. In FIG. 1 the switch is illustrated as mounted to the stanchion above the table top where it is accessible to a person seated in chair 12, although it is within the scope of this invention that the switch may be positioned at other locations on the canopy unit. When the canopy unit is used in locations where A.C. power is not available, the battery is connected to the motor by operation of a selector switch 27 shown in FIG. 4 as mounted to the battery housing '7.

FIG. 2, a cross-sectional elevation of the structure illustrated in FIG. 1, shows an electric motor 16 mounted within an aerodynamically shaped motor housing 17 secured to the upper end of the canopy stanchion within the confines of the lower canopy part. The canopy parts are disposed in tiered relation coaxially of the stanchion. An aperture is formed in the upper central portion of the lower canopy member within the radial extent of the upper canopy member and preferably coaxially of the stanchion. The motor and the motor housing are disposed concentric to and below this aperture. The motor has a rotatable shaft 18 extending upwardly coaxially of the canopy parts to an end adjacent the aperture in the lower canopy part. A fan having a plurality of radial blades is secured to the upper end of the motor shaft and is rotatable upon energization of the motor.

While the canopies in the preferred embodiments of the invention shown in the drawing are fabricated from a rigid material such as sheet metal or plastic, it is within the scope of the present invention that the canopy may be fabricated from fabric and be collapsible in the fashion of a conventional umbrella. The lower canopy part, in such case, preferably is constructed to define the aperture described above and between the aperture and its outer radial extent is fabricated of fabric supported on ribs hinged to a central ring defining the aperture. The upper canopy part preferably is fabricated of rigid material as shown in FIGS. 1, 2 and 3.

Since the canopy parts are spaced apart by brackets 19, a duct is formed from the exterior of the canopy underneath the upper canopy part to the aperture. An annular shroud ring 32, forming a partial Venturi tube section within which the fan revolves, is secured to the lower canopy part peripherally of the aperture. The vent formed between the canopy parts is sufficiently large in cross-sectional opening to allow free flow of air into the Venturi duct without appreciable aerodynamic losses. Upon operation of the fan, air is drawn into the Venturi tube through the vent between the canopy parts, as indicated by arrow-tipped lines 20 representing streamlines of air flow for discharge toward the table. The fan is disposed within the annular shroud ring and cooperates with the fan closely adjacent the tips of the fan blades to prevent recirculation of air around the tips of the fan. Prevention of recirculation increases the air-moving efficiency of the fan and prevents the fan from windmilling or creating eddies at the ends of the blades. The streamline configuration of the motor housing assures that air moved by the fan flows smoothly, downwardly, and outwardly toward the table. If desired, the direction of rotation of the motor may be reversed or the pitch of the fan blades may be reversed so that air is evacuated from the space underneath the canopy and passed outwardly through the vent between the canopy parts. Electrical conductors are connected to the motor through a hollow raceway 24 axially of the stanchion after being properly switched, of course, as aforesaid. At its lower extermity the stanchion opens into the electrical receptacle box which, in turn, opens into the electric storage battery compartment housing storage battery 22. Axles 23, rotatably mounted in pillow-block bearings 42, secured to the underside of the battery receptacle, are connected to rotatable wheels engaging the ground and supporting the battery receptacle.

It is a feature of this invention that the canopy cooperates With the fan to increase the efficiency of the fan over situations to which the fan is unshrouded. The configuration of apparatus shown in FIG. 4, wherein the fan is disposed below the aperture in lower canopy part 4 and has its blades extending radially beyond the aperture to adjacent the lower canopy part, provides a bathe circumferentially of the fan. Because the canopy has a greater radial dimension than the fan, the canopy acts as a bafile for the fan and has the efiect of increasing the aspect ratio of the fan blades so that the fan has a greater effective diameter than when operating in an unbaffie condition and thereby moves more air per revolution than when the same fan is unbafiied. The baflie effect prevents leakage of air over the tips of the fan blades and thereby prevents wind-milling of the fan. The fan may therefore rotate slowly and still move the desired quantities of air. Shroud ring 32 defining the Venturi tube (FIG. 2) is a special case of the fan baffle feature of the present invention.

It can be seen that the table ensemble fits somewhat loosely about the stanchion (see FIG. 2) to provide lateral support for the stanchion and canopy assembly and yet provide for axial movement of the table vertically of the stanchion. When it is desired to move the canopy and table unit, the table itself may be raised upwardly along the stanchion and secured to the stanchion by a pin connection (not shown) so that the battery receptacle then can be Wheeled about without interference from the table.

FIG. 3 illustrates a phantom lines the approximate location of fan 15 relative to the upper and lower canopy parts.

FIG. 4 illustrates a second preferred embodiment of the present invention in which motor 16 is mounted within battery receptacle box 7 rather than to the upper end of stanchion 3. Fan shaft 18 extends axially of the stanchion from exteriorly of the upper end of the stanchion to within the battery housing. The lower end of the shaft is connected thorugh a speed reduction means to the drive motor. The speed reduction means may be, for example, a gear mechanism, a belt and pulley drive, or friction drive discs. The upper end of shaft 13 is rotatably supported by a bearing 26, preferably a ball-bearing assembly, supported in a bearing mount housing 25 secured to the upper end of the stanchion. In the structure illustrated in FIG. 4, annular shroud ring 32 (illustrated in FIG. 2) is deleted. Accordingly, blades 15 of the fan are extended substantially adjacent the lower canopy part to assure adequate flow of air without wind-milling of the fan, as described above. Since the fan is enlarged over the fan structure shown in FIG. 2, it is preferred that the mechanical speed reducing means he used in the structure of FIG. 4.

It is preferred in many cases, however, that mechanical speed reduction means not be used between the fan and the drive motor. FIG. 5 illustrates an alternate preferred embodiment of the invention wherein motor 16 is mounted in a housing connected to the lower end of the stanchion and is directly coupled to fan shaft 18 which extends upwardly through the hollow stanchion raceway to the fan propeller. Since it is desired that the fan rotate at a relatively low velocity, it is preferred that motor 16 (illustrated in FIG. 5) be a multi-pole motor. Low angular velocities of the fan are preferred so that an undesired downward blast of the air toward the table is not produced. A high velocity blast of air may produce unhealthy drafts and also prevent use of the table for purposes of eating and the like. It is desired, however, that a substantial quantity of air be moved by fan to assure that the beneficial effects of the canopy be manifested over an area under the canopy sufficient to encompass several persons seated around the table. In practice, the dimensions of the canopy and a capacity of the fan are coordinated with the geometry of the article with which the ventilated canopy is used.

In the embodiments of the invention shown in FIGS. 4 and 5, an internal combustion engine equipped with a silencer may be installed in housing 7 and coupled therein to the fan shaft.

FIG. 6 illustrates an alternate embodiment of the canopy structure in which a plurality of louvered apertures 38 are provided in the upper central portion of the canopy instead of the duct illustrated in FIGS. 2 and 4. The canopy structure illustrated in FIG. 6 is provided by a plurality of semi-spherical sectors which preferably are releasably fastened to provide that the canopy may be dismantled for storing during the winter in locales where the table unit is not used throughout the year. Louvered apertures are preferred to prevent the passage of rain or foreign particles through the canopy.

The present invention also provides structure which is adapted for use in commercial establishments or at lawn parties wherein a plurality of tables are utilized. Tables such as those shown in FIG. 5 are normally powered by electricity supplied through extension cords run over the ground. The presence of such extension cords is not desired where large numbers of persons are present. In the structure illustrated in FIG. 7 electrical power is supplied to the fan from overhead, such as through a, drop from an electrical outlet disposed over the area within which a plurality of tables are disposed. The canopy illustrated in FIG. 7 is comprised of a lower part 4 and an upper part 5 generally in accord With the structure illustrated in FIG. 2. Drive motor 16 for fan 15, however, is mounted to the upper canopy part coaxially of stanchion 3 by means of brackets connected between the motor and the interior surfaces of the upper canopy part. Fan shaft 1% depends downwardly of the motor to centrally of an annular Venturi shroud ring 32 secured to the lower canopy part and within which fan 15 cooperates. An annular air-flow diffusing or directing ring 33 is disposed interiorly of and below the shroud ring adjacent the upper end of the stanchion. A diffuser cone 34 is mounted to the upper end of the stanchion within the diameter of the diffuser ring and further serves to direct and deflect air discharged from the fan. The diffuser ring may be stationary, or it may be adjustable relative to the shroud ring in order that the direction of discharge of the air from the fan may be varied. lhe alignment of the dilfuser ring is determined by the choice of persons seated around the table; do they wish to have the air discharged directly upon them, or do they desire to be cooled indirectly by air aspirated by the discharge from the fan. Electric power for the fan is supplied through a conduit 36 extending upwardly from an aperture centrally of the upper part of the canopy. A service cord or electrical drop 38 is passed through an insulating header 37 in the conduit remote from the canopy and thence to the motor.

PEG. 8 is a side elevational view of the housing for an electrical storage battery 22. Housing 7 provides a door 40, mounted on hinges 39 and having a handle 4- 1, through which the battery is inserted into and removed from the housing for servicing and recharging. If desired, a battery charging unit may be provided integral with the housing, although this is an optional feature insofar 6. as the present invention is concerned. An electrical receptacle 8, for supply of alternating current by means of an extension cord, is secured to the upper portion of the battery housing. A circuit selector switch 27, operable to select between alternating current power for the motor or direct current power from the battery, is provided in the receptacle housing.

In applications Where a storage battery is not to be relied upon for provision of electrical power to the motor, the structure at the lower end of the stanchion may be simplified to provide the structure illustrated in FIG. 9. A receptacle housing it for receiving an extension cord receptacle 8 is secured to a flanged sleeve which in turn is secured to the lower end of stanchion 3. The receptacle housing is supported on the ground by a plurality of feet 43 of suitable material such as rubber, plastic, metal, or any other desirable material sufficient to support the weight of the canopy and its associated air moving means.

In the preferred embodiments of the invention described above the air moving means has been comprised of a rotatable fan having a plurality of radially extending blades. It is within the scope of the present invention that the air moving means comprise a centrifugal blower. FIG. 13 illustrates a canopy 4 provided in conjunction with a centrifugal blower having a scrollcase 50 supporting a rotatable impeller (not shown) of the blower. The scrollcase defines an inlet or intake port 52 and an air discharge diffuser cone 51 mounted interiorly of the canopy, the remainder of the blower being supported exteriorly of the canopy by connection of the scrollcase to the canopy.

FIG. 10 is an electrical schematic diagram for a preferred embodiment of the invention, as for example the embodiment illustrated in FIG. 9. Electrical power is supplied to receptacle 8 and thence through on-off switch 6 to a protective fuse or circuit breaker 44 and to motor 13 which may be of the synchronous or asynchronous type. It is preferred that one side of the circuit be electrically grounded as a safety precaution.

As a further safety precaution to persons seated around table 1, a step-down transformer 46 is provided at a location removed from the table receptacle 3 being connected to the transformer by a suitably equipped extension cord 45. FIG. 11 shows a schematic diagram for an embodiment of the invention using a step-down transformer.

FIG. 12 presents, in schematic form, the circuitry of a further preferred embodiment of the invention adapted for the operation either on alternating or direct current. A step-down transformer 46 is connected with receptacle 8 by a suitably fitted extension cord 45. A selector switch 27 is disposed in the circuit for selection of alternating current from the transformer or of direct current from storage battery 22. The selector switch is connected through an on-off switch and a fuse to motor 16 which preferably, in this case, is a universal series alternating or direct current motor.

It was mentioned above that, in some cases, slow speed operation is desired for fan 15. In many instances, however, it may be desired that fan 15 be operated at one of two speeds depending upon the use to which table 1 is put. FIG. 14A illustrates an exemplary motor control means wherein a multi-pole motor having for example, twelve poles circumferentially of the armature, is regulatcd as to speed by variations in the manner in which two separate groups of poles are connected one to another relative to the armature. As illustrated is FIG. 14A, fields F1 and F2. are each comprised of an equal number of pairs of poles. An n-pole, double-throw switch 53 is provided between these fields such that, when the switch is thrown to the left (see FIG. 14A) the fields are connected in series so that the pole groups are added together and the motor rotates at its slower speed. When switch 53 is thrown to the right the fields are in electrical parallel so that the effective number of poles equals the number of poles in each pole group and the motor rotates twice as fast as when connected in the series connection.

In FIG. 14B motor 16 preferably is a universal series motor wherein speed is varied by selective connection of a selector switch 54 to one or the other of resistances 55 and 56, the resistances having different ohmic values so that these resistances are selectively coupled in series with field P1 of the motor. By varying the resistance associated with the field, the rotational speed of the motor is varied.

It has previously been mentioned that the present invention provides means for dispelling insects from around the vicinity of the table with which the ventilated canopy is equipped. The motion of the fan blades has an adverse psychological effect on insects, particularly upon insects which have mosaic or multi-lens eyes. Such eyes are responsive primarily to motion and the effect of the slowly moving fan blades of the ventilated canopy is sufficient to prevent insects from congregating in the vicinity of the table. The insect repelling features of the invention may be enhanced by coating the fan blades with a brilliantly colored enamel or laquer which contrasts with the color of the canopy.

From the foregoing description it is apparent that the present invention provides novel and effective structure for increasing the utility of outdoor patio-type tables or other articles of terrace furniture through the provision of means for circulating air in the vicinity of the associated article of furniture. The apparatus of the present invention is portable and is useful in a variety of environments since the apparatus may be operated either by alternating or direct current electric power or by a gasoline engine. The apparatus is inherently safe since the electrical circuitry is grounded to prevent shocks. Alternating current preferably is supplied by means of a step-down transformer disposed at a location removed from the canopy. Particular embodiments of the present invention are demountable so that the structure may be stored conveniently when not in use.

Although but a few embodiments of the present invention have been illustrated and described above, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing the scope or spirit of the present invention. While the foregoing invention has been described in conjunction with specific embodiments, this has been by way of example and illustration only and not as a limitation on the scope of the present invention.
