3,095,173 MOVABLE MOUNT Anthony N. Paruolo, Norridge, 11]., assignor to Advertising Metfl Display (30., Chicago, Hi, a corporation of Illinois Filed June 20, 1961, Ser. No. 120,879 9 Claims. (Cl. 248-124) This invention relates to a readily movable or portable mount, and more particularly relates to a readily movable mount for a window air conditioner. The mount is so constructed as to be manually pulled or pushed from room to room with a minimum of effort and is adjustable to conform with the sills of windows disposed at varying distances from the fioor level. This application is a continuation-in-part of my co-pending application Serial No. 96,175, now abandoned, which was filed March 16, 1961 and entitled Movable Mount.

Window air conditioners are normally adapted to cool certain limited volumes of air within a house. Usually a window air conditioner is of such cooling capacity that it is able to cool the air within the room in which disposed to a desired temperature. Because of the limited cooling capacity of window air conditioners, the cooling effect is not realized in rooms located some distance from the conditioner.

Due to the weight and size of the normal window air conditioner, it is usually inserted by means of a permanent or semi-permanent installation in a window of a room in which cooling is particularly desired. Quite often air conditioners are permanently installed in the windows of bedrooms whereby the temperatures within such room are maintained comfortably low during hot summer nights. However, during the day, little or no benefit from such a bedroom conditioner is obtained by a housewife working in a distant kitchen or living room,

and consequently, the conditioner may be allowed to remain nonoperative until night.

If, however, a window air conditioner could be readily moved into and installed with ease in a minimum amount of time in any desired room of the house in which cooling effects are desired, a single conditioner could etficiently cool a room, such as a living room, during the day time and be moved to a bedroom to cool the latter room during the night.

It is an object of this invention, therefore, to provide a novel, movable mount particularly adapted to assist in readily moving a window air conditioner to a desired window location in a house or ofiice, adjacent which cooling effects are desired.

It is another object of this invention to provide a movable mount for a window air conditioner which is adapted to readily position a supported air conditioner in proper disposition relative to a variety of window openings normally found in a home or other building structure.

It is a further object of this invention to provide a readily movable mount for an air conditioner which is so constructed as to assure ready movement of an air conditioner disposed thereon over plane surfaces with substantially no danger of tipping the mount or the air conditioner mounted thereon.

It is still another object of this invention to provide a readily movable mount for an air conditioner which is simple and lightweight in structure, and although adjustable, of sturdy construction so as to move and support in safety window air conditioners of substantial size and weight.

It is yet another object of this invention to provide a novel mount for an air conditioner or the like, which not only facilitates movement thereof, but which also functions as an integral part of the installation, dispens- 3,095,173 Patented June 25, 1963 I ing with additional supporting structure cost and installation.

It is another object of this invention to provide a mount construction employing novel locking sleeves which prevent extensible frame portions from moving or vibrating relative to supporting frame port-ions, thereby assuring a sturdy assembly in all positions of use.

It is a further object of this invention to provide a movable mount for an air conditioner or the like employing novel floating anchor means which assure secure enga-gcment of the air conditioner to the mount, as will hereinafter be explained in greater detail.

The above and other objects of this invention will become more apparent from the following detailed description when read in the light of the accompanying drawings and appended claims.

In one embodiment of this invention, a readily movable mount, particularly adapted for use with a window air conditioner, is provided. Such mount comprises a first lower frame portion having spaced, vertical tubular members in which a spaced pair of rods or tubular members of an upper frame portion which are of L-shaped configuration and lesser diametr-ic dimensions are telescopically received. Superposed transverse channel members, one of which is connected to lower frame portions engaging the vertical tubular members of the lower frame member and the other of which is connected to upper portions of the smaller-diameter L-shaped members, assist in maintaining the telescopically engaging elements of each pair in fixed spaced relationship.

Opposed parallel guide means are secured to terminal horizontal portions of said L-shaped frame members and supportingly engage opposed carriage means, reciprocally movable in the horizontal plane, on which an air conditioner may be mounted. A rotatable threaded rod member threadedly engaging a tapped opening of the lower transverse channel and pinned at its upper end limit to the upper transverse channel comprises a regulating means whereby the position of the upper frame portion may be regulated relative to the underlying frame portion.

In the normal course of use, the mount which is readily manually pulled or pushed with the assistance of casters mounted on the lower frame portion thereof is moved adjacent a window from which an air conditioner disposed on the mount is to project. The vertical position of the air conditioner is regulated by the threaded rod after which the conditioner may move into the window opening by means of the horizontally movable carriage members, as will hereinafter be explained in greater detail.

In a modified mount construction the telescopic engagement between the upper and lower frame portions is rendered vibration free by means of threaded locking sleeves. The sleeves threadedly engage upper end portions of the larger telescopically engaging tubular portions of the frame and concomitantly urge a split ring into the tube interval.

The modified mount also employs a carriage construction employing a floating anchoring nut which assures proper engagement with the supported air conditioner. The various features of the modified construction may be employed singly with the mount construction first hereinafter described.

For a more complete understanding of this invention, reference will now be made to the drawings wherein:

FIG. 12 is an enlarged fragmentary view of an adjustable anchor means employed in the movable mount of FIG. 8.

Mount Frame Referring now more particularly to FIG. 1, a mount 10, particularly adapted to support a window air conditioner and assist in readily moving the same over substantially level surfaces is illustrated. The mount is seen to comprise a lowermost tubular frame element 12, which is substantially rectangular in configuration, on which four casters 14 are mounted at corner portions thereof. The casters are freely pivotal about their pintles and, accordingly, mount 10 may be readily pushed or pulled in any direction on a plane surface.

Supported in substantially vertical planes on opposed portions of the lowermost tubular frame element 12 are opposed parallel, vertical frame members 16 which may be bolted or otherwise suitably affixed to the underlying frame element 12. One vertically disposed tubular arm 16a of each frame element 16 telescopically receives a lower leg portion 18L of an L-shaped rod or tubular member 18 in the manner most clearly seen in FIGS. 1 and 3. Upper portions of frame elements 16 are maintained in spaced relationship by means of transverse bar 20 which may be secured at opposed end limits to frame elements 16 by screws 22 or other equivalent securing means.

Mount Guides Secured to distal horizontal leg portions 18a of the L-shaped members 18 are opposed guides 24. The guides 24 may be secured to distal arm portions 18a of'each member 18 by means of nut and bolt assemblies 26, most clearly seen in FIG. 5, or other equivalent securing means.

A transverse channel member 28, most clearly seen in FIGS. 1 and 6, maintains opposed distal portions 18a of members 18 in parallel, spaced relationship, and as willbe noted from FIG. 5, may be secured to portions 18a of L-shaped members 18 by nut and bolt assemblies 26 which also secure guides 24 to distal legs 18a. Thus, L-shaped members 18, transverse channel 28 and the opposed parallel guides 24 will move as a unit relative to the underlying legs 16a of frame elements 16 in which lower vertical portions 18L of the L-shaped members 18 are telescopically received.

Frame Regulating Means It will be noted from FIG. 6 that the transverse bar 20 and transverse channel 28 are in superposed relationship in the vertical plane and, accordingly, enable threaded rod 30, most clearly seen in FIGS. 1, 3 and 4,-to serve 4- as a connecting means for regulating the interval between the upper portions of mount 10 and the lower frame portions of such mount. Because of the telescopic engagement between leg portions 18L and tubular members 16a, it is apparent that the upper portions of the mount 10 are extensible relative to the lower frame portions of the mount. The threaded rod 30 has handle 32 secured to the lower terminal end limit thereof. Threaded rod 30 also threadedly engages tapped nut 34 fixedly mounted on lower transverse member 20. Since the upper terminal limit of rod 30 is rotatable relative to transverse channel 28 but does not axially move relative thereto, rotatable movement of rod 38 will raise or lower channel 28 (depending upon the direction of rotation) and the other mount elements movable therewith relative to transverse bar 20 and the lower frame elements of the mount.

M onnt Carriage Members As will be more clearly seen from FIG. 5, guides 24 have a substantially C-shaped cross sectional configuration and are arranged in face-to-face relationship. It is the purpose of guides 24 to supportingly receive opposed carriage members 36 and gmide the same in the course of limited reciprocal movement in the horizontal plane. Opposed carriage members 36 are maintained in parallel spaced relationship by means of interconnecting tubular handle member or rod 38, more clearly seen in FIGS. 1 and 6. End portions of rod 38 are secured to opposed carriage members 36 by means of screws 40 (see FIG. 1) or other equivalent means.

Each of the opposed guides 24 has a substantially horizontally disposed supporting surface portion 42 over which wheel members 44 journalled in opposed end portions of each carriage member 36 may rotatably move. In addition, to facilitate movement of each carriage member 36 over support surface 42 of each guide 24, a hard plastic projection 46 mounted in portion 42 of guide 24 may be employed to maintain the level disposition of surface portion 37 of each carriage member 36 and in addition reduce friction in the course of movement of each carriage member relative to the supporting guide.

It will also be seen from FIG. 5 that longitudinal edge portion 48 of each guide, which is hook-like in cross sectional configuration, defines an elongate recess 50. Upper off-set longitudinal edge portion 52 of each carriage member 36 having spaced rollers 54, one of Which is clearly seen in FIG. 5, mounted thereon, reciprocally moves in [recess 50 and is guided by edge portion 48 in the course of carriage member reciprocal movement, as is apparent from FIGS. 4 and 5. Hook portion 48 of each guide prevents undue lateral movement of the opposed carriage members 36 and interconnecting tubular member 38.

It is seen in FIG. 5 that normally, carriage members will readily move over supporting surfaces 42 of guides 24 with the assistance of wheels 44 and projections 46 tending to reduce friction between the relatively moving members. However, in the course of a pushing movement of the opposed carriage members 36 relative to guides 24, an upward thrust may be given to the carriage members as a result of which, rollers 54 will readily engage inner surface portions of longitudinalportion 48 of the guides 24 and thereby facilitate relative movement between the guide and the carriage portions.

Limits of Carriage Movement One end limit of reciprocal movement o-f-the carriage assembly, comprising opposed carriage members 36 and interconnecting member 38, and the guides 24 isdefined by raised flanges 56, more clearly seen in FIG. 1, defining one longitudinal end limit of the lower surface portion 42 of each guide 24. The longitudinal movementof the assembly relative to guides 24 in the opposite direction is defined by engagement between terminal ends 58 of carriage rod 38 and a distal longitudinal edge 60, more clearly seen in FIGS. 1 and 6, of the transverse channel 28.

Locking Levers In the normal course of use, an air conditioner is initially mounted upon opposed carriage members 36 of mount by means of screws which threadedly engage tapped apertures disposed in opposed side portions of an air conditioner, such as the air conditioner 64 illustrated in FIG. 2. The securing screws have enlarged heads and shank portions which traverse apertures 66, which do not permit passage of the screw heads. Apertures 66 are predeterminately spaced to conform with the air conditioner tapped apertures and formed in each carriage member 36. Enlarged apertures 68 in the vertical wall portions of guides 24, more clearly seen in FIG. 1, facilitate the initial securing of the air conditioner to the opposed carriage members 36.

In the course of the initial securing of the air conditioner to the mount, the reciprocally movable carriage assembly must have carriage elements 36 thereof in substantially co-extensive relationship with the supporting guides 24 in the manner illustrated in FIG. 1. In such relative disposition apertures 66 of carriage members 36 will be concentric with apertures 68 of guides 24.

To facilitate the attaining of this desired co-extensive relationship between the carriage members and the guide members, pivoting locking elements 7 0, one of which is more clearly seen in the fragmentary view of FIG. 7, are employed. Locking elements 70 comprise metal strips which are pivotally mounted in an oif-center condition, whereby one end portion always has a tendency to pivot up and away from the bar member 38. The longer heavier portion extending from the pivot point has the natural tendency to pivot downwardly. The end limit of the pivotal movement of each element 70 is defined by one edge 71 of recess 73 disposed in the carriage member on which mounted, as is more clearly seen in FIG. 7.

It will be noted from FIG. 1 that in the co-extensive relationship depicted between the guides and carriage members, the upwardly pivoting terminal end portion of each locking lever 70 will pivot upwardly, partially projectin-g through opening 72 formed in each longitudinal portion 48 of each guide member 24. It will also be seen from FIG. 1 that in the co-extensive relationship between the guides and carriage members illustrated, movement of the carriage members in one direction is prevented by the raised flange portions 56 which function as stops. The lever members 70 prevent longitudinal movement of the carriage members on which the air conditioner is mounted in the opposite direction by striking edge portion 74 of each recess 72. Edge portions 74 comprise a portion of guides 24 and define one end limit of each opening 72.

Mount Use After an air conditioner, such as conditioner 64, has been secured to the opposed carriage members 36 by means of screws passing through aperture 66 of each carriage member, the mount and air conditioner may be readily moved into a desired window opening for purposes of cooling a volume of air adjacent the window in which the conditioner is disposed. Prior to mounting of the conditioner on the mount 10 and prior to movement of the mount, the upper extensible carriage assembly and supporting L-shaped members 18 are preferably retracted into the lowermost position by means of threaded rod 30 in order that the center of gravity of the air conditioner and mount assembly may be as low as possible, thereby maintaining danger of tipping such assembly at a minimum.

Upon arrival at a window opening, such as the opening of window 76 of FIG. 2, the following steps take place. The air conditioner 64 is raised until the conditioner and supporting carriage members are approximately one-half inch above the sill of the window from which the air conditioner will project. Following this vertical movement of the air conditioner and attached carriage assembly, upper portions of the opposed locking levers 70 are depressed and simultaneously, with the levers in the lower non-locking position, the conditioner and attached carriage assembly are horizontally moved into the window opening.

To-assist in this movement, one foot of the person installing the air conditioner may engage ribbed member 77 composed of rubber or other non-skid material disposed on the leg of the lower frame portion 12 disposed beneath carriage bar 38. As previously mentioned, engagement of the terminal end limits 58 of carriage assembly bar 38 and distal longitudinal edge 60 of transverse channel 28 will prevent the air conditioner and carriage assembly from moving beyond a certain maximum distance into the window opening.

After the air conditioner is properly disposed relative to the window sash, the air conditioner is lowered by means of handle 32 and rod 30 so that distal terminal portions of the opposed carriage members 36 which now project beyond distal end limits of guides 24, in the manner illustrated in FIG. 6, rest on the window sill. The window sash is then lowered and any expandable adapter members inserted in place so that no exposed area exists between the periphery of the air conditioner and lateral portions of the opening normally defined by the window.

The end portion of the air conditioner projecting from the window opening is now locked between the lowered 'WlIlClOW sash and the underlying window sill. In such condition the adjusting handle 32 for threaded rod 30 may again be employed for purposes of raising the air conditioner and carriage assembly until the portion of the air conditioner projecting into the window opening possesses a slightly downward tilt. Such tilting is desired to assure proper drainage of any moisture which may be removed by the air conditioner from the conditioner so that such moisture will be discharged outside the room. Since the movement of the carriage members and conditioner relative to the guide portions 24 of the provided mount have moved the center of gravity of the conditioner toward the window opening, the last-mentioned upward movement of the threaded rod will in effect provide a tilting action of the conditioner, at which time carriage rollers 54 may come into play.

It will be most apparent from FIGS. 4 and 5, the latter figure disclosing securing of the upper terminal end limit of threaded rod 30 to transverse channel 28 by means of cotter pin and washer assembly 80, that the threaded rod 30 is not centrally disposed relative to the two

transverse members

20 and 28. Inasmuch as the center of gravity of air conditioners is not in a central position, the point of engagement of threaded rod 30 with transverse channel 28 and the disposition of channel 28 relative to L- shaped arms 18 are predeterminately selected to assure the application of force to the channel by the threaded rod at approximately the center of gravity of the conditioner. As a result of such arrangement, any lifting force applied to the conditioner will be most effectively utilized when the carriage assembly is in the position seen in FIG. 1.

Modified Mount Construction FIGS. 8 through 12 of the drawing relate to a modified movable mount construction. It will be apparent from these latter figures that portions of the modified movable mount 90, which are the same 'as those in the movable mount 10 of FIGS. 1 through 7, bear the same reference numerals.

Modified Frame Construction It Will be noted from FIG. 8 that although the illus trated movable mount possesses a lowermost tubular frame element 12 and casters which are substantially the same as

components

12 and 14 illustrated in FIG. 1, the

frame components attached to the tubular element 12 of the mount 96 differ from those illustrated in FIG. 1.

Secured to the lowermost tubular frame element 12 in FIG. 8 are opposed substantially vertically disposed tubular members 92 which are welded to element 12 at 94. Tubular elements 96 reinforce the connection between vertical elements 92 and frame element 12 by being welded to elements 92 at 98 and to element 12 at 190.

It will be appreciated from a comparison of FIGS. 1 and 8 that since the vertical tubular members 92 of mount 91} are vertical throughout their entire length, lower vertical portions 18L of the frame members 18 may be longer in FIG. 8 than in FIG. 1 because of the absence of any curved portion of the telescopically receiving frame portion of the mount. By employing a lowermost frame construction, such as illustrated in FIG. 8, portions 18L of the uppermost frame may be longer, providing greater stability in the mount 96 than is obtained in the mount 10 of FIG. 1.

Inasmuch as the lowermost frame components of the mount 90 are composed of a few parts which are welded together, the cost of such assembly is less than that of the lowermost frame components of FIG. 1. As will be seen from FIG. 8, tubular members 96 of the lowermost frame construction may be of a smaller outside diameter than the telescopically receiving tubular members 92, thereby further assisting in lessening the cost of this construction over that illustrated in FIG. 1.

Locking Sleeves As above pointed out, the telescopic engagement between vertical members 18L of the upper frame portion of mount 99 and vertical tubular portions 92 of the latter mount is substantially the same as the telescopic engagement between the frame components 18L and 16a of FIG. 1. Mount 90, however,is distinguished from the movable mount 10 of FIG. 1 by being provided with a frame locking means to assure a fixed relationship between telescoping members of the upper and lower frame portions.

As is seen in FIG. 8, the upper frame assembly of the mount 90' possesses the transverse channel 28, transverse member 20, nut 24 and threaded rod 30, which are employed in the mount 10 of FIG. 1. However, because of manufacturing tolerances, slight play is always present between the vertical frame portions 18L and the lower frame portions 16a of the movable mount 10. The movable mount 94) of FIG. 8 eliminates any play between the telescoping frame components by employing locking sleeves 102 and'split rings 104, illustrated in FIG. 11.

In the normal course of use of the movable mount 90, the upper frame portion and attached conditioner can be moved into the desired vertical position and inserted in a window opening in the manner previously described in connection with movable mount 10. Once the conditioner is in place, locking sleeves 102, having the internal threads 106, threadedly engage the external threads 108 disposed on the upper end portion of each vertical tube component 92 of the lowermost frame portion of the illustrated movable mount 90.

In the course'of threadedly engaging the upper portion of the vertical frame tubular members 92, split rings 104 are urged into the interval between vertical tubular portions 18L of the upper frame and vertical tubular members 92 of the lower frame portions of the movable mount 90. Locking sleeves 102, in conjunction with the split rings 104, assist in providing a rigid frame assembly which is substantially free of play and not subject to vibration. The sleeves 102 also assure disposition of the upper frame portion of the illustrated mount in a desired horizontal plane, regardless of the weight of the air conditioner which may be supported thereby.

8 Modified Carriage Construction I It will be noted from FIG. 9 that although the opposed guides 24 are precisely the same as the glides illustrated in FIGS. 1 through 7 of the drawings, carriage members 110 employed with the movable mount are somewhat different from the carriage members 36 of the movablemount 10 previously described.

It is apparent from FIG. 9 that no roller members, are employed in conjunction with carriage members 110. Instead, the means for reducing friction between the reciprocally movable carriage members and the supporting guides 24 comprise supporting

plastic projections

46 and 112 which are mounted in the lower supporting surface portion 42 of the guides 24-. Plastic member 46, illustrated in FIG. 9, is precisely the same as that illustrated in FIG. 5. The plastic members 112, which are mounted in opposed end portions of surface portion 42 of each guide 24, dispense with the need for rollers 44, illustrated in FIG. 5. 9

Although the opposed carriage members 110 of the mount 90 are maintained in spaced relationship by the same tubular handle 38, which is employed with the mount fers somewhat from that of the carriage members 36 previously described. It will be noted from FIG. 9 that an upper offset longitudinal edge portion 114 of carriage member 110 is not offset to the same degree as edge portion 52 of carriage member 36. Consequently, pivotal locking levers 116 do not traverse an opening formed in the carriage member 110, but are mounted on pins 118, most clearly seen in FIGS. 9' and 10, which project from the innermost surface of each offset longitudinal edge portion 114 of the carriage members 110. The pivotal locking levers 116 are mounted in an off-center condition whereby the longer heavier portion of the lever is disposed toward the mount handle 38', as is most apparent from FIG. 10. The end limit of this downward pivotal movement is defined by an angularly disposed stop member 129, which is welded or otherwise suitably secured to a surface portion of each carriage member 110 in the manner most clearly seen in FIG. 9. When the locking levers 116 engage stop members 120 upper stop edge portions 122 are in a position to engage edge portion 74 of recess 72 formed in each guide member 24, in the manner illustrated in FIG. 10. 1

Relative positioning between carriage members 110 and the supporting guides 24- of the movable mount 90 is assisted by means of the plastic members 112 mounted in the lower surface portion 42 of each guide. Plastic members 126 mounted on the surface portion of the longitudinal edge portion of 114 of each carriage member 110 disposed toward the terminal distal end of each hook-like portion 48 of the guides 44 also assist in maintaining desired carriage-guide relationship. In order to provide proper spaced relationship between the bottom portion of each carriage member 110 and the vertical wall portions of each guide 24, an elongate channel portion 110A is welded or otherwise suitably aflixed along the lower longitudinal edge of each carriage member 110 in the manner illustrated most clearly in FIG. 9.

Carriage Members Adjustable Anchors 128 are formed in the vertical wall portions of each carriage member 110. Movably positionably in each enlarged aperture is a pivotally mounted anchor or nut member 130, most clearly seen in FIGS. 10 and 12. Since the nut members 130 are pivotally movable within the carriage aperture 128, a screw member may engage an air conditioner tapped aperture (which is formed in the course of conditioner manufacture) with relative ease in the course of securing such conditioner to the carriage members. The floating anchors 130 eliminate completely any problem of aperture misalignment which may be occasioned by manufacturing tolerances and encountered in the course of securing an air conditioner to the opposed carriage members of the movable mount 90.

It is seen from the foregoing disclosure that the modified mount construction illustrated in FIGS. 8 through 12, various changes may be made in the basic mount construction provided by this invention which will facilitate attachment to the mount of an air conditioner, as well as positioning of the air conditioner in a window opening.

It is apparent, therefore, that a novel mount has been provided for a room air conditioner which enables the same to be readily moved from window to window within a house or other enclosure so that selected portions of a home or ofiice may be cooled as desired. Thus, a conditioner may be readily moved by means of the abovedescribed mount to the window of a kitchen in day time so that cooling effects may be imparted to that portion of the home most frequently used by the inhabitants during the day time, and at night the conditioner may be readily moved by means of the mount 10 to a bedroom window so that cooling effects may be imparted to the bedroom during the night.

A window air conditioner which had heretofore required permanent or semi-perrnanent installation may now serve a number of rooms, as desired, during the day because of the rapidity and facility with which the conditioner may be moved to any desired window.

The foregoing description has illustrated the ease with which the conditioner may be adjusted to be properly disposed witlun window openings of various heights. The novel mount structures above described also clearly demonstrate that the air conditioner may be moved in substantially complete safety without danger of tipping.

It is apparent from the foregoing that a number of changes may be made in the mount structures which will provide a resulting construction which does not depart from the scope of hte invention described. It i intended, therefore, that this invention be limited only by the scope of the appended claims.
