Figures 10 to 21 show other modified forms of the collapsible standard embodying my invention. Inthe several figures of the drawing 'like reference numerals indicate like parts.
The collapsible standard forming the subject matter of my present invention is an improvement over the collapsible "standard 5,0 illustrated in my earlier applic-ation Serial '.No. 110,565. In my presentinvention the standard has been considerably simplified in .construction over the standard illustrated in the application above referred to and in simpllfying the construction of the standard it h as been made more Vpractical in its adaptat1on to a flash light with less`cost added to the manufacture of a flash light equipped with this standard. As illustrated in the figures of the drawing the standard is attachedl to the flash light body 1' by means of a saddle which comprises a pair of'lugs 2 and 3 having upwardly curved extensions that conform to the cylindrical wall of the flashlight body 05 and are fastened thereto by means of suit` able rivets or screws. The lugs project from the flash light body and form a. narrow slot into which engages the upper end of the link 4. The end of he link 4 is pivoted between the lugs 2 and 3 by means of a suitable pivot stud that also clamps the links in'place so as to provide frictional contact between the link and the lugs that will hold thelink in any angular position in which it is placed.
The lower end of the link 4 is Ypivotally attached to the base member 5. This base member has the shape of a channel having a wide bottom and a. narrow top just wide enough to admit the link 4 when the standard is collapsed. At the left hand end the bottom of the channel is cut away and the sides there-of brought together to form a narrow bifurcation at the end of the channel in which the lower end of the link 4 is ivoted. A pivot stud 6 passes thru the bi urcated end of the channel and the 'lower end of the link 4 located therein and by means of suitablewashers the stud clamps the end of the link in place at one .end of the base. This allows the link to turn on the end of the base with considerable frictional resistance 'suiicient to allow the link to support the flash light body when placed in an angular position without collapsing into the base.
T ie pivoted lower end of the link 4 is enlarged .and on its peri hery is provided a. shoulder 7 This shoulder is adapted to engage the bottom of the base made up of the channel member 5 so that when the link is swung out of the channel member it is held against further movement after the shoulder 7` is in contact with the bottomof'the base as illustrated in Figure 3. This holds the or base 5. In this way a four point support to the baseso as to is provided at the bottom of the base 5 wheneverthe cross bar 8 is turned to a positionvat right angles to the base l5 as illustrated lin Figures 2 and 4 from a position parallel to the bottom of the base as illustrated in Figure 1.
When the standard is not in use the relation of the parts of the standard is illustrated in Figure 1 in which the link 4 has been swung into the channel or base member 5 and both the base member and the link are swung against the sid-e of the flash lightbody 1. In this position the different parts of the collapsible standard occupy a mm1- mum amount of space so that its addition to the flash light body is not objectionable from the standpoint of the user of such aiight when using it as a'strictly manually held flash light.
The standard ed to form a base for the flash light. This is done by simply swinging the base and from the body on the pivot stud that connects the link 4 to the flash light body and then swinging the base member 5l away ,from the link 4 until a lfurther movement is arrested by the lug 7 as. above pointed. out. tated on the under side of the base member and placed from a parallel position to a position at right angles to it in order to increase the supporting area of the base. With the standard thus extended it can be set on l any horizontal or nearly horizontal surface to support the flash light without manual assistance. swung on the upper end of the link 4 and placed in any angular positionwith relation direct the light from i the flash light in any desired angular direction.
short sl^eve or ring'l10 is provided for the purpose of positively locking the l1-nlz.4 in .the predetermined angular posit-ion 1n which-it is placed with relation'to the base .5 -when the base is swung` away from the link until a further` movement 1s arrested' Th is sleeve encircles by the shoulder 7 the link 4 and is adapted to slide back and yforth thereon. When the standard is c ol-- lapsed the sleeve is moved close to the pivotal connection between the link and the .i flash light body and is held in place inthis is, however, quickly extend-l The cross bar 8 is then ro' The flash light bodv can be? position by the end of the base 5 between which and the lugs 2 and 3' sufficient space is left for this purpose.
When the standard is-fully extended as above pointed out the sleeve 10 slides down on the link until the right hand end engages yinto the angular notch 11 provided in the top of the base 5. The engagement of the 4sleeve with the base prevents the link 4 from swinging down against the -base when the standard is set up and supports the flash light. The friction in the pivotal joint between the link and the base can be reduced to a minimum by the use of the locking sleeve as the locking sleeve alone will hold the link in its extended position, no matter i how much weight is placed on top of the link; Between the sleeve 10 and the shoulder 7 of the link 4 the base is thus held against movement in either direction so that when the standard is swung away from the flash light to be extended, its base can only be placed 'in one position and in this position it is'locked until it is again desired to collapse'the standard against the flash lightv body;
To collapse the standard all that is necessary is to turn the flash light body over s o` that the standard projects upwardly therefrom. The *sleeve 10 will then slide down on the link 4 out of engagement with the notch inthe base 5 and against the lugs 2 and 3.
The base is then free to be fold-cd against A the link until the link is nested therein. Both the link and base are then folded against the body of the flash light and the cross bar 8 is turned parallel to the base 5.
In the modification illustrated in Figures 5 to 7 inclusive the link 12 is pivoted with its-upper end to the lugs 13 and 14 and the lugs are in turn attached to the flashlight body.- Thel base member 15 is pivoted to the lower end of the link 12. In the collapsed position of the standard the link is nested in the channel forming the base member 15 which instead of being located with its bottom on the outside of the link as illus- 4trated in Figure 1 is now located with its bottom between the link and the Hash light body as illustrated in Figure 5. When the standard is therefore extended the link and base member together are first swung 'away' from the flash light body until a point is reached at which the base member can be swung awayfrom the left of the link tothe right thereof until the base is held against further movement by the engagement of the shoulder 16 on the link 12 with the inverted bottom of the channel forming the baseV member 15.
The cross member 17 which is pivoted on the base member 15 is then position practically parallel to the base to a position at right angles to 1t. This cross member is provided with the depending turned from a -ber as illustrated in Figures 5 and 6 and for this purpose the sides of the channel.
are cut away to receive these depending flanges.v
When the cross member 17 is extended the supporting base is ready to be placed in position to support the fiash light. The weight of the fiash light keeps the shoulder 16 ot the link in contact with the base thus bracing the link in the predetermined angular position. For the purpose of locking the base on the link against closing after it has been extended the pivot hole 20 in the lower end,
of the link 12 thru which extends the pivot pin 21 carri-ed by the base member 15, may be elongated 'so as to provide for the base member a short lateral motion after it has been moved to its extended position. With such a. motion, the left hand end of the inverted bottom of the channel engages into the short slot 22 forming a continuation of the shoulder 16 and this engagement will then hold the base member locked in place on the link so that it cannot be swung in..-
either direction until the end of the inverted bottom of the base member is again withdrawn from the slot 22 for th-el purpose of collapsing the standard.
As illustrated in FiguresS and 9 the collapsible standard may be mounted on the flash light body by means of a removable clamp member 50. `Thismember comprises a flexible loop having both ends bent outwardly therefrom to provide the lugs 51 and 52. Lug 51 has the hollow rivet 53 attached thereto with its head 54 located on the outside Vof the lug.- On the inwardly projecting hollow shank of the rivet 53 is pivoted the ripper end ot the link 12 and next to it is placed the friction washer `56 and the end ot the hollow shank of the rivet peened over on the outside of the washer to clamp the upper end of the link 12 between the washer 56 and the inside of the lug 51. On the other lug is carried the clamping screw 55. This screw is mounted i-n the slot A provided in the lug '52. For this purpose the shank 57 of the screw isy grooved behind the head thereof and the reduced diameter of this shank is placed into the slot so that the screw after being inserted into the slot cannot drop out again. A washer 58 is placed between the head of the screw and the outside of the lug if desired..
The mounting of thestandard above de- .scribed is placed over the flash light body and is then closedl asjillustrated in dotted" lines in Figure 8. and .clamped in place in this position by means of the clamping screw which is threaded into the hollow rivet until the curved body of the mounting is drawn tight against the body of the flash light to lirmly hold the collapsible standard on the fiash light..
In the modifications illustrated in Figures 10 to 13 inclusive I have illustrated the collapsible standard as having a base that is long enough to straddle the pivotal connection between the link and the flashlight body. This is illustrated in Figures 1l and l2. In this modified form the channel forming the base of the standard is wider at the top, practically the ull length thereotl except at the end where the link is pivoted thereto.
of the link as indicated at 60`so that the rectangular sleeve can be located'at this reduced section ot' the link and have a limited ,movement thereon that will either bring it in the position at one end as illustrated in Figure 1l in which it serves to lock the standard open or it will bring it into the dotted line position at the. other end ot .its movement illustrated in Figure 10 in which the link with the sleeve can telescope into the enlarged base formed by the chair' nel. Y
In the modifications illustrated in Figures 14 to 21 inclusive the base ofthe standard is notlhinged to the base but is separately iastened thereto. Figures 14 to 16 inclusive comprises a link made up of a rod and a base lformed by the channel 66. The rod has areduced threaded extension 67 at the lower end with which it can be threaded into the hollow rivet 68 provided in the channel 66 for the purpose of holding the cross bar 69 in place thereon. When extended the standard appears as illustrated in Figure 14 and in its Ycollapsed -form it-appears as illustrated in Figure 15. To collapse the standard the link formedby the rod is threaded out of the base and then separately snapped over the link to be held in place thereon until needed.
The modification illustrated in Figures 17 to 19 inclusive is similar to that illustrated in Figures 14 to 16 except that instead of a round rod a rod having a rectangular cross section is used for thc link. The base 7 0 for this link is a rectangular tube or sleeve and I in the middle at one side thereof is provided The standard illustratedl in l This' forni of construction makes it possible to reduce the width of a portion shown in which the link is made up of a flat bar 75 having its lower end turned outwardly with a. slot 77 extending from this outwardly turned end to' approximately the middle ofthe length of the link. A collapsible base made up of two cross bars 7S and 79 is adapted to slide back and forth on the link and for this purpose is provided with the rivet that extends into the slot 77 so as to guide the collapsible base from the position illustrated in Figure 21 to the position illustrated in Figure 20. In the first position the cross bars 78 and 79 are located alongside the link and parallel thereto while in the second position the cross bars \extend at right angles thereto and when extended :t'orm a base in the form of a cross at the bottom of the link.
