2.3 Claims. (Cl. 13s 20 1 This invention relates to garden, beach, terrace, and other such large umbrellas, which will be hereinafter referred to, for convenience, as garden umbrellas. The invention relates more particularly to tiltable garden umbrellas.

the tilting thereof and with a separate mechanism for effecting the raising and lowering of the umbrella. In the construction of the Pereira patent two distinct mechanisms, each equipped with a handle, are provided, one to operate the mechanism effecting the raising and lowering of the umbrella andthe other for actuating the tilt mechanism. While the construction of the Perei-ra patent represents an important advance in the umbrella art, in that it enables both the tilting vof the umbrella and the raising and lowering of the heavy canopy, utilizing little energy for these purposes, the use of two separate mechanisms for eifecting the raising and lowering and the tilting does add to the cost of'the umbrella and does result in an umbrella construction having two casings and handles associated therewith positioned near the upper portion of the lower pole, which casings and handles impart a-bulky, sometimes objectionable appearance to the umbrella.

It is an object of this invention to provide a garden umbrella which maybe readily raised or opened, titled, and closed, which umbrella is relatively simple in design and inexpensive to construct, and this with the expenditure of little energy by the user.

Another object of this invention is to provide a garden umbrella in which the mechanism which effects the. raising and lowering of the umbrella also accomplishes its tilting e A Still another object of this invention is to provide such umbrella in which the operating mechanism is for the most part concealed from view and which therefore presents an attractive, streamlined appearance.

Other objects and advantages of this invention will be apparent from the following detailed description thereof.

. In accordance with this invention a tiltable garden umbrella is provided which is equipped with mechanism for raising and lowering it, which raising mechanism also effects its tilting.

Inthe accompanying drawings forming a part of this specification and showing, for purposes of exemplification, preferred forms of this'invention, without limiting the claimed invention to such illustrative instances, and in which like parts are indicated by like reference characters;

Fig. 1 is a fragmentary vertical section through a garden umbrella embodying my invention, the umbrella being shown in the upright position;

Fig. 2 is a fragmentary vertical section, on a somewhat larger scale than that of Fig. 1, with the umbrella shown in the tilted position;

Fig. 3 is a fragmentary vertical section showing the portion of the lower pole in which the wind-up shaft is mounted;

Fig. 3a is a vertical section taken in a plane passing through line 3a3a on Fig. 3;

Fig. 4 is a fragmentary vertical section of a modified form of tiltable umbrella embodying this invention; in the modification of Fig. 4 the operative mechanism for effecting the tilting of the umbrella is disposed in the lower pole, whereas in the embodiment of Fig. 1 this operative mechanism is disposed in the upper pole of the tiltable umbrella;

Fig. 5 is a fragmentary vertical section, on a somewhat larger scalejthan Fig. 4, showing the umbrella of Fig. 4 in tilted position;

Fig. 6 is still another modification of the invention, showing a different form of linkage connection between the upper pole and the operative mechanism for effecting the tilting of the umbrella disposed in the lower pole;

.Fig. 6a is a fragmentary vertical section showing the same linkage connection as employed in Fig. 6, but .in'

which this linkage connects the lower pole with the operative mechanism for effecting tilting of the umbrella disposed in the upper pole;

. Fig.- 7 is a fragmentary vertical section of still another modified form of the invention, in which the operating mechanism for effecting tilting of the umbrella is disposed mainly exteriorly of the umbrella poles and not within the umbrella poles as in the modification of Figs. 1 to 6a inclusive;

Fig. 11 is a fragmentary vertical section of still another modification in which, like in that of Figures 9 and 10, opening of the umbrella is effected by moving the runner downwardly rather than upwardly. The modification of Fig. 11 differs from that of Figs. 9 and 10 chiefly in that the actuating mechanism for effecting tilting of the umbrella is positioned in the lower pole and not in the upper pole as in the case of Figs. 9 and 10;

Fig. 12 is a fragmentary vertical section through a portion of the umbrella pole showing still another modification of the invention, namely, one in which an air cylinder is employed to take the place of the loaded spring in each of the other modifications of Figs. 1 to 11 inclusive; and

Fig. 13 is. a fragmentary vertical section of still another modification in which a compressible rubber or other elastic and compressible plastic is employed in lieu of the air cylinder of Fig. 12 or the loaded spring of the other modifications.

Referring to Figs. 1 to 3 of the drawings, 20 indicates a lower hollow pole provided with a casting 21 disposed in the upper end thereof. Rotatably mounted in pole 20 is a wind-up shaft 22 provided with a'handle '23 for elfectingrotation thereof, which handle is equipped with Patented Oct. 25, 1955" a spring detent pin 24, arranged to enter one of the pair of openings and 26 disposed diametrically opposite each other in the wall of the hollow lower pole 20.

Upper pole 27 is hollow and has suitably fastened to the lower end thereof a casting 28, whieh has an extending portion 29 (Fig. 2) positioned between the extensions 30 of lower casting 21 and pivoted as at 31 to the lower casting 21. A push-tube 32 is mounted for reciprocal motion within hollow pole 27, being guided for such motion by the bearings 33 near the top of the pole and the bearings 34 forming the top end of casting 28. Pushtube 32 is hollow and is provided near the top with a slot 35, in which slot is mounted a pulley 36 which is rotatably mounted on the push-tube 32 to, move there: with. Pulley 36 extends through a slot 37in the wall of upper pole 27, the latter slot being of sufiici'ent length to permit limited movement of the pulley 36 as hereinafter more fully described.

.A runner 38 of the conventional type, to which are pivotally fastened the stretchers 39 of the umbrella, is mounted for movement up and down of the umbrella pole, to effect the raising and lowering of the umbrella. As conventional, the stretchers 39 are pivotally fastened to the ribs 41 of the umbrella, which in turn are pivotally secured as at 42 to the crown or notched member 43 suitably secured tothe top of the upper pole 27. A wire rope or steel cable 44 has one end fastened to the runner 38 as at 45, passes over the pulley 36, down through the push-tube 32, through the

castings

21 and 28, and has the other end fastened to the wind-up shaft 22.

A loaded spring 45 has end 46 pinned or otherwise suitably secured to the push-tube 32, and has the other end bearing against the upper portion of casting 28. Secured to the lower end 47 of the push-tube 32 is one end of a link 48, the other end of which is pivoted to a second link 49. End 50 of link 49 is provided with a slot 51 in which is slidably disposed a shoe 52. Pin 53 passes through the shoe and is suitably mounted in casting 21; shoe 52 is free to rotate on pin 53 and vice verse, so that these two parts can move relative to each other. Link 49 is pivoted at 54 to casting 21, which as above noted is secured to lower pole 20.

A stop ring or other stop member 55 is fastened to the upper pole 27 at the position indicated in Figs. 1 and 2 'of the drawings. When the runner 38 engages the stop ring 55 the stretchers 39 and ribs 41 are so positioned that the canopy of the umbrella is fully opened.

Desirably, the wind-up shaft 22 is provided with a brake B, which may be of any desired construction. In the embodiment of the invention shown in Figs. 3, and 3a the brake B comprises a split collar 56 secured by pins 57 to the lower hollow pole 20, so that the collar 56 cannot rotate with the shaft 22. The compression ex e'rted by this split collar on the wind up shaft 22 can be adjusted by adjusting the bolt 58 which threadedly engages in the threaded openings 59 in the split collar 56. Thus, by loosening or tightening the bolt 58 more or less pressure will be exerted on the shaft 22 to permit it to turn more or less freely. y

In the operation of the umbrella of Figs. 1 to 3:1 inclusive, with the parts in the position shown in Fig. 1, the loaded spring 45 exerts pressure, not only to counterbalance the weight of the canopy but also to maintain the umbrella in the vertical position shown. 7

Assuming the umbrella is in a closed position and it is desired to open it, it is only necessary to turr'rthe handle 23 to wind up the Wire rope 44 on the wind-up shaft 22, which will effect elevation of the runner 38 to the position .shown in Fig. 1, with consequent raising or opening of the umbrella. To maintain the umbrella in the open position, detent 24 is engaged in

openirig

25 or 26. In this position of the parts the umbrella is locked in open position. I d M d If it is desired to tilt the umbrella, the winding of rope 4 44 mi wind-up shaft 22 is continued. As this takes place stop 55 prevents further upward movemento f the runner 38. Accordingly, continued winding movement will pull down on pulley 36 through the wire rope 44, causing this pulley and the push-tube on which it is mounted to move downwardly, slot 37 permitting such movement. This downward movement effects a downward thrust on link 48, causing link 49 to pivot about its pivot 54, which in turn causes the upper pole to tilt relative to the lower pole about pivot 31. When the upper pole has been tilted to the desired extent the detent 24 is permittedto enter its

opening

25 or 26; as the case may be, thus locking the umbrella in the tilted position. It will be understood the umbrella can be tilted more or less in one direction depending uponthe amount of wire rope 44 wound onto wind-up shaft 22. When tilted to the desired extent the tilt is locked by detent pin 24 engaging

opening

25 or 26 as the case may be. ,,Once the detent 24 is removed from the

opening

25 or 26, spring 45 forces the push-tube in an upward direction and thus returns the tilted umbrella to the vertical posi-' tion. This action, of course, is not only controlled by the brake B but also by the operator who, through pressure exerted on handle 23, can control the rate of movement of the umbrella fromthe tilted to the vertical position and vice versa and also the rate of opening or closing of the umbrella.

, To close the umbrella, it is only necessary to turn handle .23 in the direction which will permit the runner 38 to descend under the weight of the canopy and the umbrella frame.

. In the modificationof Figs. 4 and 5, the mechanism for effecting tilting of the umbrella is disposed in the lower pole 20, just the reverse of the arrangement of Figs. 1 and 2., In the modification of Figs. 4 and 5 the wind-up shaft 22 is mounted for rotation on push-tube 32 disposed in the hollow lower pole 20 but has its ends positioned in slots 60 in the lower pole 20 so that this wind-up shaft can move up and down. along with the push-tube 32, from the position shown in Fig. 4, the lower position, in which positionthe umbrella poles are in alignment to the position shown in Fig. 5, the upper position, in which position the umbrella poles are at an angle to each other, i. e., the umbrella is tilted.

The pulley 36 in the modification of Figs. 4 and 5 is fixedly mounted on the upper pole 27 as at 61. Wire rope 44 has one end fastened to the runner 38, passes over pulley 36, and has the other end fastened to the wind-up shaft 22.

Inth'e operation of the modification of Figs. 4 and 5, to raise the umbrella, handle 23 is rotated, rotating shaft 22 to wind up the wire rope or steel cable 44, raising the runner 38 .to the position shown in Fig. 4 where it abuts the stop 55. In this position the umbrella is fully opened and the parts are disposed as shown in Fig. 4 with the wind-up shaft 22 at the base of slot 60. If it is desired to tilt the umbrella, the handle 23 is rotated further. This exerts a downward pull on pulley 36 which is fixed, and hence an upward pull on thepush-tube 32 in which the wind-up shaft 22 is mounted for rotation. Upward motion is thus imparted to the push-tube 32 which rises, the ends of the wind-up shaft 22 rising in slot 60. As the push-tube 32 rises it exerts an upward thrust on link 48, which actuates the connecting link 49 about its pivot 54, to tilt the umbrella about pivot 31 as shown in Fig. 5.

It will be understood that the modification of Figs. 4 and 5 is provided with a detent corresponding to detent 24 and elongated slots 25' and 26 to receive the detent 24 to lock the umbrella in both the tilted position and also in the. vertical open position shown in Fig. 4. Slots 25' and 26 in general correspond to

openings

25 and 26 of 3; these slots are elongated to receive the detent 24 on handle 23 as the wind-up shaft moves up and down in slot 60, as hereinabove described. To restore the umbrella of Figs. 4 and 5 to the vertical position, it is only necessary to remove detent 24 from its lockedposition in opening 25, vor 26'. .Spring 45 will then act to restore the umbrella to the vertical position and to maintain it insuch position. To close the umbrella, handle 23 is turnedto lower the runner 38; the weight of the canopy and the umbrellaframe structure aids in effecting the closing of the umbrella. V Y p The modification of .Fig. 6 differs from that of Figs. 4 and 5,,in that instead of the

linkage mechanism

48 and 49 connecting the upper end of the push-tube 32 with the casting in the upperpole, a link 71 is employed, connecting the upper. end of push-tube 32, with an extension 72 on the casting at the base of the upper pole. This casting at the baseIof the upper pole is pivoted as at 73 to the casting 28 at the top of the lower pole. I v

lnthe modification of 6, as in Figs. 4 and 5, pulley 36 is fixed to the upper pole 27 and the wind-up shaft is mounted for up and down movement in slots 60 in the lower pole. .In operation, tilting of the umbrella is accomplished b y further rotation of the wind-upshat't 22, after the runner 38 engages the stop 55, causing the pushtube 32 tomove upwardly as hereinabove explained in connection with Figs. 4 and 5, exerting an upward thrust iiii'zhee'e position of the parts the umbrella is in fully opened position, with the two

poles

20 and 27 in vertical alignment and spring 45 under load to maintain the poles in alignment through the action of collar 84, arm 83,

links

48 and 49.

If it is desired to tilt the umbrella, the wind-up shaft 22 is actuated to further wind the wire rope 44 thereon. Since the split runner cannot .move upwardly further be- 7 cause of its engagement with the stop 55 this action exand thus causing the upper pole to pivot relative to the lower pole through the action exerted by link 71 as shown inFig.6. I @w Themodification of Fig. 6a differs from Fig. 6*c'hiefly in thatpush-tube 32 and associated loaded spring '45 are disposed in the upper pole rather than in the lower pole, as shown in Fig. 6. .In the modification of Fig. 6a the pulley 36 is mounted for limited up and down movement and the wind-up shaft 22 ismounted for rotary movement on the lower pole 20 as in Figs. 1 to 3 inclusive. Tilting of the umbrella inthe modification of Fig. 6a is effected when thepush-tube is moved downwardly by the winding of thewire rope or steel cable-44on the wind-up shaft 22, as explained above, in connection with the modification of Figs. 1 to 3. This causes thepush-tube32 to move downwardly, exerting a thrust on link 71a, which causesthe upper pole to pivot relative to the lower pole as shown in Fig. 6a. i The modification of Figs. 7 and 8 differs from those hereinabove described, particularly that of Figs. 1 to 3 inclusive,; in that the operating mechanism for efiecting raisingand lowering of the umbrella and its tilting is disposed chiefly externally of the upper umbrella pole rather than within this pole. I

In Figs. 7 and 8 the upper pole 27 is provided with a bearing 81 extending exteriorly thereof, in which slides an actuating rod 82. The upper end 83 of rod 82 is provided with a collar 84 encircling pole 27. Loaded spring 45 is positioned under tension between collar 84 andpin 85 passing through pole 27. The rod 82 is also provided with an arm 86 extending laterally through the slot or opening 37 in pole 27. Arm 86 is provided with a pin 87 on which is rotatably mounted the pulley 36 over which passes the wire rope 44. End 89 of rod 82 is pivotally fastened to one end of link 48, the other end-of which is pivotally secured to link 49 pivoted at 54 to an extension of the casting 21. 3

In the embodiment of the invention shown in Figs. 7, 7a and 8, runner 38, as best shown in Fig. 7a is in the form of a split-runner provided with a slot or opening 90, define d by the cammed or curved sides 91 and 92 defining the slot 90. Actuating rod 82 is disposed in the slots90, the camrned or curved sides -91and .92 of the runner-being disposed on opposite sides of the rod:82 so that the latter does not interfere with the movement of the runner up and down the umbrella pole'27 toeffect opening and closing of the umbrella.

In the operation of theernbodiment of the invention shown in Figs. j7, 7a and 8,when it is desired to open the umbrella thewinid-up shaft 22 is actuated to Wind up'the wire rope. 44 thereon, thusraising the split runner ,38 until it engage's'the stop 55, as shown in Fig. 7. In this erts a downward pull through pulley 36 on rod 82, arm 86 moving downwardly in slot 37. The downward motion of rod 82 through

links

48 and 49 effects the tilting of. the umbrella poles about pivot31, as shown in Fig. 8. Theumbrella is locked in tilted position by the detent pin 24 engaging in one of the

openings

25 or 26 in the umbrella pole 20.

To restore the umbrella to the vertical position, it is only necessary to remove the detent pin 24 from its locking opening. When this is done the loaded spring 45 will cause the rod 82- to move upwardly to etfect restoration of the upper and lower poles to the position of vertical alignment shown in Fig. 7. The umbrella can, of course, be closed or lowered by actuating the wind-up shaft 22 to unwind the wire rope 44, permitting split runner 38 to descend to the position where the umbrella is closed. I Y

' Inthe modification of Figs. 9 and 10 an umbrella is shown which is opened by moving runner 38 downwardly rather than upwardly along pole 27, just the reverse of the operation required to effect opening and closing of the umbrella inthe modification of Figs. 1 to 8 hereinabove described. i

In the construction of Figs. 9 and 10 the upper pole 27 is provided with a slot 101 in which moves a pin 102, the ends of which are secured to the runner 38. Runner 38- has pivotally secured thereto as at 103, one end of the stretchers 39, the other end of which is pivotally secured to the ribs 41. .When the umbrella is in the open position shown in Fig. 10, stretchers 39 are inclined downwardly somewhat relative to the horizontal.

Fig. 9 shows the umbrella closed. If it is desired to open the umbrella the wind-up shaft 22 is actuated by its handle 23 to wind the wire rope 44 thereon. This exerts a downward pull on pin102, to which one end of wire rope 4 is secured as at 105, moving runner 38 downwardly, causing the, stretchers- 39 to move to open the umbrella, i. e., to move to the position shown in Fig. 10. When pin 102 reaches the top 104 of the push-tube 32 in the position shown in Fig. 9, the umbrella is fully opened and the upper and lower poles are in vertical alignment.

If it is desired to tilt the umbrella the wind-up shaft 22 is actuated to continue the winding of the wire rope 44 thereon; .This causes the pin 102 to move downwardly in the slot 101, forcing the push-tube 32 downwardly, actuating the

links

48 and 49 to tilt the umbrella about its pivot 31. Slot 101 is of sufficient length to permit the desired extent of tilt to be imparted. When pin 102 is positioned at the bottom of slot 101 as is the case in Fig. 10, the umbrella is tilted to the maximum extent. Hence slot 101 should be of a length to permit tilting to the desired extent. Within the limits of tilting permitted by the length of slot 101, the extent of tilt can be controlled by the amount of wire rope 44 wound up on the shaft 22. As in the other modifications, the umbrella is locked in the desired tilted position by detent pin 24 engaging in one of the

openings

25 or 26 in the umbrella pole.

The modification of Fig. 11 differs from that of Figs. 9 and 10 chiefly in that the loaded spring 45 and the pushtube 32 are disposed in the lower pole 20 rather than in the upper pole 27. In Fig. 11 the lower pole 20 is provided with openings or longitudinally'extendiug slots 22a, through which the wind-up shaft 22 extends. These slots 22a permit upward movement of the wind-up shaft relative to the lower pole, as explained more fully hereinafter.

in the operation of the modification of Fig. 11, to open the umbrella wind-up shaft 22 is actuated by handle 23 to wind thereon the flexible cable or wire rope 44. This action exerts a downward pull on pin 102 aflixed to runner 38 causing the runner to move downwardly while pin 102 moves in its slot 101 in the upper pole 27, opening the Umbrella. When the umbrella is opened pin 102 is disposed at the bottom of slot 101. Further actuation of the wind-up shaft 22 causes the push-tube 32 to rise in pole because pin 102 resting in the base of slot 101 ean no longer move in a downward direction and hence an upward pull is exerted on the wind-up shaft 22, which pull elfects an upward movement of pushtube 32. Such upward movement of the wind-up shaft is permitted by the slots 22a in hollow pole 20, through which slots shaft 22 extends as noted above. The modification of Fig. '11, like that of Figs. 4 and 5, is provided with elongated slots (only one of which is shown in the drawing and indicated by numeral to receive detent 24 irrespective of the vertical position of Wind-up shaft 22 on lower pole 20.

'The modification of Fig. 12 employs, in lieu of the loaded spring of the other modifications hereinabove described, a cylinder containing gas under pressure. This cylinder 109 surrounds the push-tube 32 and in the form of the invention shown in Fig. 12 comprises a cylindrical lower casing 110 provided with suitable packing '111, forming a gas-tight seal where the cylinder walls abut push-tube 32. An upper cylinder casing 112 which is slidable within cylinder 110, the sliding joint between the two cylinders being suitably packed by packing 113 forming a gas-tight seal, has at its upper end a gas inlet valve 114. Air, gas such as nitrogen, or other inert gas may be supplied through the valve 114 to charge the cylinder 109 to any desired pressure. Suitable packing 115 is provided to form a gas-tight seal between the wall of cylinder 112 in sliding engagement with push-tube 32 and the latter. A stop ring 116 is secured to the pushtube 32. The pressure within cylinder 109 forces the upper wall 117 of the cylinder 109 into abutting engagement with stop ring 116 at all times.

In the operation of the modification of Fig. 12, when the wire rope 44 is wound on the wind-up shaft 22 the 'pus'hrtube 32 is moved downwardly by the action of pulley 36, as described for example in connection with the modifications of Figs. 1 to 3. This causes the stop .ring 116 to move downwardly, increasing the pressure \withinthe cylinder 109, which action, just like the action of the loaded spring in the modifications hereinabove described, provides the necessary force for restoring the umbrella from the tilted to the vertical position when the detent 24 is removed from locking

openings

25 or 26, as the case may be, permitting this action to take place. The pressure Within cylinder 109 acts through the stop ring 116 on the push-tube 32 and through the linkage connections between the latter and the umbrella poles, to maintain the poles in vertical alignment when the umbrella is in open position.

The modification of Fig. 13 differs from that of Fig. 12 chiefly in the substitution of a compressible rubber or other plastic ring 121 surrounding the push-tube 32 and disposed in the space defined by the top of casting 28 and a stop ring 122 secured to the push-tube 32 by a $013 pin 123. Rubber or other plastic cylinder 121 is inserted under compression so that at all times it exerts pressure on the stop ring 122 and through the latter and pin 123 on the push-tube 32, similar to the action of the loaded spring 45, to maintain the umbrella poles in It will be understood that in all modifications described, the wind-up shaft 22 may be provided with asuitable brake, such for example as that shown in Figs. 3 and 3a. Furthermore, while the use of a gas pressure eylinder or other compressible rubber or plastic material inthe case of the modifications of Figs. 12 and 13 have been shown as associated with a push-tube located in theupper pole, they may be used in the other modifications 'in lieu of the loaded spring located in the lower pole. In the modifications of Figsf 7 and 8, in which the actuating mechanism for effecting tilting of the umbrella is disposed exteriorly of the umbrella pole, in lieu of the loaded spring, a gas pressure cylinder or compressible and expandable rubber ring or other member may be employed. Any of the above modifications may have the lower pole suitably mounted, say in a table or other support, so that the pole can be rotated and thus turn the tilted umbrella to provide shade Where desired.

It will be noted that the present invention provides a garden umbrella which may be readily opened, tilted, and closed, and this with the expenditure of little energy on the part of the user.

It will be further noted that the mechanism which raises and lowers the umbrella also effects its tilting. This results in an exceptionally attractive, simple, com,- pact construction. Thus, in the case of the modifications of Figs. 1 to 6 inclusive, 10, 11, 12 and 13, only the'lower umbrella pole is provided with a handle for actuating the wind-up shaft 22. The rest of the mechanism for raising and lowering the umbrella, and its tilting, is disposed within the umbrella poles. Accordingly the preferred embodiments of the invention have an exceptionally attractive, streamlined appearance. It is for this reason that the modifications of Figs. 1 to 6 and 9 to 13 (both inclusive) are preferred to those of Figs. 7 and 8, in which latter figure the actuating rod 82 for efiecting tilting of the umbrella is disposed exteriorly of the umbrella pole and thus tends to give the umbrella a somewhat more complicated and therefore less attractive appearance.

Since diiferent embodiments of this invention could be made without departing from the scope of the invention, it is intended that all matters contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Thus, while the invention has been described in connection with umbrellas, it will be understood it is not limited thereto but can be used in connection with any awning, canopy or other such structure involving an upper pole which such structure is adapted to be raised and lowered and in which the upper pole is tiltable relative to the lower pole.

What is claimed is: p

1.
