(c1.`287-108)` This invention relates to Visors -or glareshields, and-in particular to such devices which' are capable of being adjusted laterally around an axis and alsolongitudinall-y along the axis. y

One object 4of this invention is to provide a visor having a supporting rod and tube structure cooperating to facilitate longitudinal adjustment along the rod while impeding swinging around the rod, the'latter adjustment being accomplished by means outside the tube.

Another object is to provide a visor having a supporting rod of non-circular cross-section with at least one attened area running longitudinally thereof, this flattened area being engaged by a yielding means within` the visor supporting tube 1 so as to lfacilitate longitudinal adjustment while impeding lateral swinging of the tube around the rod. l

Another object is to provide a visor-'as set forth in the preceding objects wherein the visor supporting rod has a lpair of longitudinallyextending flattened areas disposed at an angle to each other and engaged by yielding means within the visor supporting tube,

The rod is encircled by'a visor-supportingtube having-elongated spring mountedl inside the ltube springs -force the rod against an angular portion ofthe tube and provide a .frictional engagement which tends to hold the visor 4in its adjusted position-'lengthwise of the rod. The visor panel is attached tol the visor-supporting-tube. Stops are pro'videdbetween-the-rod and tube for limiting the motion o-f vthe ntube .relatively tothe rod.

'The end-of the rod which vemerges from .the tube is 4tapered andis urged vinto Ifrictional Lengagement Vwith a 2conical bore by' a coil spring within a cavity Vina supporting arm which Llikewisecontai-ns -the-lbore. y Thissupporting-arm has anadditional tapered portion'for mounting it in the usual supporting bracket 4attached to some suitable portion-of the vehicle.

' The modiiicationfof Figures 5 to -8 -is-generally similar to the preferred `form lbut the -visor-supporting rod is of approximately-triangular-crosssection with rounded or iiattened edges. V-Two-of the walls of `a.. triangular portion -areA urged into engagement with the 'internal walls of a visorsupporting tube -of approximately triangular cross-section .by means of an elongated spring pressing against the third Wall-of lthe-rod. The remainder of the .modied construction is similar to `that Yof the principal -form =of the invention.-' Y I JBy this-construction, either in the -preferredfor modified form of the invention, thefvisorfis prevented from rattling, `even though-subjected to considerable vibration, Ior while `the vehicle ris being `driven overy rough' roads. The elongated springs yand the peculiar cross-section of the visor-supporting lrod cooperate lto eliminate any such rattling-at its very source. This rattling in longitudinally adjustable Visors has vbeen a serious defect vinsuch'- visors vof the `prior `art and' has 4given manufacturers much trouble, `expense anddissatisfaction arising'from this defect.

Referring to the'drawing in detaiLFigure l shows -a preferred'embodiment of the invention as consisting gener'ally of a visor support ygenerally designatedy Jlll carrying a visor-supporting rodg'enerally designated -If|, which in turn is encircled -by a Avisor-supportingV tube generallyfdesignate'd I2 havingja frame `I3"carryin`g the visor panel lll. The Yvisor jsupport HJ is providedwith a tapered stem |15 projecting from the side thereof and adapted to Ibe :received in a corresponding tapered bore in a conventional Vbracket (-nolt shown), such asthat disclosed in the Jacobs Patent No. 2,084,584` of June 22, l1937. Such va bracket is mounted `in any convenient position upon 'the-car body, suchr as lon the Lheader `conin engagement `with` the flattened areas. These 55 stituting the 'forward partof the vehiclerooff The visor support I is provided with a conical bore I6 having its axis at an angle to the axis of the tapered portion I and having an enlarged recess I1 coaxial therewith.

The visor-supporting rod II is provided with a correspondingly tapered portion I8 frictionaily engaging the bore I6 and extending into the recess I1 where it is provided with a coil spring I9 having one end seated against the inner end of the recess I1 and the other end seated against the head of a screw 20 threaded into an axial hole 2l in the end of the visor-supporting rod II. this means the mating conical portions I6 and I8 are urged into frictional engagement with one another, so that the visor attached to the rod I I may be adjusted by swinging it around the axis of the rod II.

The visor-supporting rod II is of partially arcuate cross-section (on its upper side 22) and is provided with longitudinally-extending flattened portions 23 and 24 arranged atan angle to one another and extending lengthwise of the rod II. Theiiattened portions 23 and 24 are engaged byundulating elongated springs and 26 secured to the inner walls 21 and 28 of the visorsupporting tube I2. The walls 21 and 28 are approximately parallel to the flattened portions 23 and 24 and constitute extensions of the tube side wallsZS and and the upper walls 3I and 32.

v 'Ihe upper walls 3I and 32 are likewise approximately flat and are disposed at an angle to one another, meeting along a rounded junction 33 (Figure 4). Extensions 34 and 35 of the tube walls 21 and 28 abut one another and are secured to one another in any suitable way, such as .by welding. The elongated springs 25 and 26 are securedas at 36 and 31 respectively (Figure 3) to the visor-supporting tube I 2.

The visor-supporting tube I2 is provided with a st op 3 8 struck inwardly from the material of the tube and leaving the aperture 39 in the surface thereof (Figure l).

its travel to the left. Similarly, the bent end 4I o f thespring 2 5 enters a notch 42 near the end of the rod II and engages the wall 43 therebetween, halting the visorwhen it is pulled too far tothe right along the rod I I.

The frame I3 is securedai', its ends to the visor tube portion by welding or other suitable means, and serves to support the visor panel I4 mounted thereon. The latter may be attached to the-visor-supporting tube by a suitable adhesive or by means of staples or other feasteners.

In operation, the elongated springs 25 and 26 yieldingly engage the longitudinally-extending flattened areas 23 and 24 on the visor-supporting rod II and urge the rounded portion 22 thereof into the trough formed by the tube portions 3| and 32. ,The engagement of the springs 25 and 23h-with, the flattened portions 23 and 24 prevent thenrotation of the tube I2 relatively to the rod I I, yet permit the former to be slid along the lat-V ter to provide for a longitudinal adjustment. j At the s arne ltime, the springs25 and 26 are powerful enoughto prevent rattling between the visor supporting rod VII and thevisor tube I2.

To adjustrthe visor panel I4 around the axis ofthe rod I I, the panel I4 is merely swung in an arcuate path, whereupon the conical end I8 of the rod II Arotates in the conical bore I6. When the visor `is released, the coil spring I9 urges the conical portions I6 and I8 into frctional engagement, holding the visor in'itS adjusted position.

This stop 38 engages the 4end 40 of the visor-supporting rod II and halts thevisor when ithas reached the limit of By this means, therefore, the visor is held in any desired position either around or along the axis of the visor supporting rod II.

In the modification of Figures 5 to 8 inclusive,

Vthe visor-supporting rod 50 is' of different crosssection from the visor-supporting rod II of the form shown in Figures 1 to 4 inclusive. The rod 50 has a conically tapered end 5I similar to the conically tapered end I8 of the rod II and similarly fitting into the visor support I0. The rod 50 is of approximately triangular cross section, with lengthwise flattened portions 52, 53 and 54. The longitudinal edges 55 and 56 are rounded and the longitudinal edge 51 is flattened, but may be also rounded if desired. The rod 50 is encircled by a visor-supporting tube also of approximately triangular cross-section and likewise having longitudinally flattened walls 6I, 62 and 63 with rounded edges 64, 65 and 66 respectively. Extension flanges 61 and 68 are joined to one another, as by welding, in a manner similar to the portions 34 and 35 of the preferredform of the invention.

The tube walls 6I and 62' arearranged at substantially the same angles to one another as the rod surfaces 52 and53 and the latter are urged into engagement with the former by anelongated undulating spring 69 secured as at 10 to the inner side of the wall 63 of the tube A6I). The end 1I of the elongatedspring 69 is bent in order to engage the end wall 12 of a notch 13 near the end of .the rod .50, in order to limit the motion of the visor to the right. The mo tion of the visorto the left along the rod `is limited by a stop 14 struck out of the aperture 15 in the end of the visor tube 60 (Figure 7) In theoperation of the modification of Figures 5 to 8 inclusive, the triangular rod 50 is urged into the longitudinal trough or groove between the tube portions 6I and 62 by theelongated spring 69. The frictionbetween the rodand tube serves to hold the portions in their adjusted positions after the tube 50 is moved along the rod 50. The adjustment -of the visor panel I4 aground the axis of the rod '50 is the same as that set forth in connection with the preferred form of the invention. The spring 69 urges the rod 59 into engagement with the inner wallsof' the tube 60 with a suiiicient force to prevent rattling even when the vehicle is driven over very rough roads, yet a frictional engagement is prou vided which Will hold the visor inpositionalong the rod at any desired location.
