This invention relates to improvements iny a parasol construction, Yparticularly such as may be used with garden tables, and the like.V

One of the objects of this invention is to provide a parasol which may be tilted atan angle, or rigidly supported ina verticalposition, the mast being so constructed atv its tilting joint as to permit the parasol to be opened or closedkwithout removing a part oi the mast. ln the past it has been commonk practice to resort to tools for eiiecting the l tilting or the mast, or to remove the upper part of the mast to lower the same. These and other purposes have been accomplished rin the present invention without sacrifice of strength in its several parts.

As an exempliiication of my invention, reference is made to the accompanying drawings in which- Figure 1 is a View in elevation of a para-y sol as used in connection with a garden table, the parasol being shown in closed position by dotted lines and in tilted position by broken lines;

Fig. 2 is an enlargedk view in elevation of the tilting joint with a portion of the tilting colla-r broken away,l v y Fig.' 8 is a vertical sectional view showing a portionV of the mast in slightly tiltedposi tion, and taken asindicated by the line 3 lof Fig. 2; Y

Fig. 5 is an elevation of the tilting joint with the mast'in vertical position 'and with the raising and lowering sleeve shown in section surrounding the joint; and

Y the table C, and may be rotatably held thereby. The mast, as shown, is made up of sections of tubing, such as 15, 16 and 17, the section preferably remaining assembled with the table and to which the .section 16 is connected as by a bayonet joint 16a.

sections

16 and 17 respectively, thek plug l18 being slotted ask at 2O toprovide-upstanding ears 21, and the plug 19 being shaped to form a tongue22 which fits within the slot 20,'the two parts being pivotally connected together' vby a pin 'Surrounding the mast limmediately below the-'pivot isa collar 2% rotatable to present' the steppedv upper ends of 'a series of slots 25 selectively' invv alignment with the tongue 22. The pr file of the tongue may beot any desired con-. tour as, for example, a protrusion 26, one side of whichlpresents anangular surface 27 adapted to bearagainst the inner edge of thel upper end of one of the slots 25 to holdthe parasol top in tilted position, theangle of tilt depending upon the position of the slot end with .whichthe tongue'coacts. v Y;

l Fig. 2 4shows 'a portion of the collar 24 bro-- lien away so asto mere clearly illustrate the shape of the kplug 18 which is of'two diametersl meeting to form a shoulder 28. Thesmallen diameter ofthe plug is'oi` a size permitting turning movement of the collar`24 thereon, and"k the larger'l diameter being substantiallyr equal to that of the tubing sections16. The collar is thus rconfined lagainst endwise movement by the shoulder 28 and the end-of the tubing 16, ythe shoulder -servin'gprimarilyas an abutment to resist upward movement of the collar in 'response toforce exertedbyi It will be seen that the parasol may when the collar has beenrotatedl to a point where -oneof the slots 25 is in alignment y'withf the tongue 22, andthat the parasol lis 'locked' against'tilting when the collar is rotatedto any other position due tothe tongue striking against the linner surface of the collar. "lhey modilied form ofcollar yshown finFig. 6 consists of a collar2eLa surrounding theears 21v below the' shoulder 28, the lower edgeoi1 the collar being formed spirallyjas at 29,'against'V which the angular surface 27l of the tongue" l bears ywhen the vparasol is'in tilted position."

It will be understood that by rotating the collar so as to bring in alignment with the tongue a portion of the collar having a longer or shorter longitudinal dimension that the parasol will be raised or lowered accordingly.

The construction of the parasol shownis of the usual type having ribs (not shown),

also struts 31 and a sleeve 32 slidable on the o mast B, and held in uppermost position by l should be of such diameter that the sleeve 32 may slide over it to permit lowering of the parasol while it remains assembled to the mast section 15. Heretofore it has been com.-

mon either to disconnect the mast above the pivotalconnection in order to lower the parasol, due to the enlarged construction of the hingodjoint, or to use a tool, such as al screw drivel', tofeectthe tilting movement of the 29. parasol; The present construction is suchas to,V overcome` these difficulties.

1. A parasol comprising a pair of mastl seetionspivotally joined end to end, a tongue il having a rigid mounting at the end of one Section and extendedto lie Within aslot at the end of the other section, and a collar rotatabl mounted on the mast section last na and surrounding a portion. of the a9 tongue therein, there being a slot formed lon gitudinally in the collar through which the tongue may protrude` in part when the one mast'seetion is swung to an angular position.

2. A parasol comprising a pair of-mast sections pivotally joined end to end, a tongue having afrigid mounting at the end of one a Sectionand extended to lie within a slot at the end of the other section,y and a collar, l-'otatablyk mounted on the mast section last` namedand surrounding a portion of the ton c therein, the collar. being provided l Wituaplurality of openings spaced at varyingdistanees from one end'of the collar, the

tongue being engageable selectively Within` tween the two sections, the collar being cut away at, places which, when registered with; thetongue, permit a limited swinging move1 ment of one section relative to the other.
