13 Claims. (Cl. 13520) This invention relates to umbrellas, and more particularly to a beach or garden umbrella 'of the tiltable type.

One of the primary'objects of the invention is to provide a tiltable umbrella of improved and simplified construction requiring minimum effort for opening and closing the canopy as well as for adjustment between upright and tilted positions.

Another object is to provide a tiltable umbrella wherein an upper shaft or handle supporting the canopy is mounted on a lower shaft or standard by means of an inclined arm or shaft in such manner that the upper shaft can be rotated on the axis of this inclinedarm for adjustment between upright and tilted positions, and especially to provide such a tiltable umbrella which includes a simple and effective lock mechanism for maintaining the upper shaft in either upright position or a selected one of a range of different tilted positions.

An additional object is toprovide a tiltable umbrella as outlined above in which the canopy is so constructed and attached to theupper shaft that it is opened by means of a force directed downwardly of the umbrella, and especially to provide a tiltable umbrella of this construction wherein the canopy is equally readily opened or closed in either upright or any tilted position.

it is also an object of'the invention to provide a tiltable umbrella having one or more of the above outlined characteristics which is composed of comparatively few and readily fabricated parts and which may be quickly and easily disassembled for carrying or storage without danger of loss of any small parts and the like.

Additional objects and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims.

in the drawings- Fig. 1 is a side elevational view showing a beach or garden umbrella constructed in accordance with the invention and illustrated in tilted position;

2,731,973 Patented Jan. 24, 1956 which is adapted for fixed mounting in the ground or the like, and a middle section 13 which forms an adjustable connection between the upper and lower sections. The upper section 10 is a straight shaft of tubular metal, and the canopy 11 is carried by a staff 15 telescoping within the upper end of shaft 10. The ribs 16 for the canopy are pivoted on a crown 17 secured to the upper end of staff 15, and the braces 18 arepivoted to a ring member 19 which is secured in fixed position on shaft 10. The upper shaft 10 also-carries an angularly extended'arm 20 of tubular stock which is secured thereon by means of a suitable Y fitting 21, and the lower end of shaft 10 and the arm 20 thus cooperate with shaft 10 to form an inverted Y. A brace 22 connects the lower ends of shaft 10 and arm 20 for purposes of adequate rigidity and includes a collar portion 23 on the shaft 10.

Opening and closing of canopy 11 is effected by means of an operating handle 25 secured to the lower end of staff 15, this connection being shown in Fig. 5 as including a plug 26 pinned within the lower end of staff 15 and carrying a' stud 27 on which handle 25 is retained by a collar'28. The operating handle 25 projects radially from upper shaft 10 through a bayonet slot 30 in the lower portion of the shaft, which may for convenience be open ended as shown. The bayonet slot 30 is provided with an offset seat 31 at its upper end, and a similar seat or detent notch 33 is formed in the lower end of shaft 10.

Fig. 2 shows the closed position of the canopy 11 in dotted lines, and in this position, the operating handle 25 will be moved to the upper end of the bayonet slot and seated 'in the seat 31 to lock the canopy in closed position. To open the canopy, the operating handle 25 is shifted out of seat 31 and pulled down through slot 30 until it can be moved over into locking position in the notch 33, and the reverse operation is followed to close the umbrella. This operating mechanism is highly advantageous, since not only does it provide for opening of the canopy by means of the straight downward pull 7 which is the most easily exerted force in handling an um Fig. 2 is a somewhat diagrammatic view showing the umbrella in upright position and also illustrating theop eration of the opening and closing mechanism for the canopy; 4

Fig. 6 is an enlarged fragmentary view, partly broken away and in section, showing the connection between the middle and lower handle sections; and

Fig. 7 is a section on the line 7--7 of Fig. 6.

Referring to the drawings, which illustrate a'preferred embodiment of the invention, the umbrella handle includes three separate sections, an upper section 10 which carries the canopy 11, a lower section or standard 12 brella of this type, but it also entirely avoids spring catches and the like which sooften tend to pinch the fingers of theuser, especially whenfirst releasing the umbrella for closing.

The middle section 13 of the umbrella standard includes a generally S-shaped centralpart 35 which is rotatably connected with both the upper and lower sections. Referring particularly to Figs. 6 and 7, the part 35 has a collar 40 welded to the lower end thereof, and this collar in turn carries a tubular extension 41. The collar 40 includes'a circumferential rib 42 proportioned to seat on the upper end of standard 12, and this collar also includes a lower portion: fitting smoothly for rotation within standard12. An inwardly pressed bead or rib 43 in part 12 forms a similar guide bearing for the tubular extension 41.

The collar 40 carries a spring latch for cooperation with lower handle section 12 to secure the part 35 in augularly adjusted relation with the lower handle. This latch 44 is shown as formed of spring wire and includes a tongue portion 45 adapted to enter one of a series of slots 46 in' the wall of the part 12, the collar 40 being slotted at 47 to receive tongue 45 therethrough. An operating button 48 for the latch projects through a suitable opening in the part 35 above collar 40, and when this button 48 is depressed} the tongue 45 will be withdrawn from latched engagement with the lower handle section 12 to permit the part 35 to be freely rotated on the axis of part 12.

There is a similar rotatable connection between the upper end of the part 35 and the arm 20 on the upper handle section 10. A collar 50 similar to the collar 40 supports anarm or shaft 51 which projects upwardly and is inclined toward the upward projection of lower handle section 12, the angle between this shaft and the projection of the part 12 being substantially equal to the angle defined by thearm 20 and part 10. The arm 20 telescopes over shaft 51 for rotation on the axis of shaft 51 on the bearing surface provided by the rib 52 on collar 50 and the rib or bead 53 in arm 20. The collar 50 supports a latch mechanism of the same construction as already described in connection with Fig. 6, the latch tongue 55 cooperating with slots 56 in the lower end of arm 20 and the operating button 58 for this latch corresponding to button 48.

With this construction as described, when the parts are assembled as shown in Fig. 3, the upper shaft can assume a vertical position in which it is parallel with the lower handle section 20, and for purposes of symmetry, the part 13 can be proportioned in such manner that the upper and lower handle sections will be coaxial when the umbrella is upright. One of the latch slots 56 in arm should be so located as to lock the upper and lower handle sections together in this position. At the same time, with the lower end of the shaft 10 thus supported as shown in freely spaced relation with the lower handle and the part 13, the operating handle is readily acccssible for opening and closing the umbrella canopy.

Tilting of the umbrella from upright position is effected by releasing the latch tongue 55 and then rotating the arm 20 on the collar 50 and shaft 51. This adjustment is easily carried out by utilizing the collar 23 as a handle, and the umbrella can be retained in desired tilted position by reengagemeut of the latch tongue 55 with a selected slot 56. Thus Fig. 3 indicates in dotted lines at 10 an intermediate tilted position of shaft 10, and also the position 10" of maximum tilt of the umbrella in which the projections of the parts 10 and 12 define an angle substantially double the angle between the parts 10 and arm 20.

In addition to this easy tilting adjustment of the urnbrella, the direction of tilt can be varied as desired by rotation of the part about the axis of the lower handle section. Such an adjustment simply requires release of the latch tongue and rotation of part 35 until the latch tongue is indexed with a selected different slot 46. In addition, disassembly of the umbrella is effected at similar speed and ease by releasing one or both of the latch tongues 45 and 55 and withdrawing the corresponding telescoped parts out of telescoping relation. At the same time, since such disassembly does not require even the temporary removal of bolts, screws or like small parts, there is no danger of loss of any such parts, and the disassembled umbrella will include only the three major handle sections as described.

While the form of device herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of device, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
