Application October 25, 1937, Serial No. 170,735

, 12 Claims.

This invention relates to hood and lid supports for automobiles, onmore generally stated, supports for liftable hinged closures. 7

Many lid supports now commonlyused have two pivotally connected arms or links which fold in the closing of the lid. The objection to such supports is that there isdanger of getting something-pinched between the folding arms, and the arms are apt to poke into something as they fold. It is therefore the principal object of my invention to provide a telescoping type support whereby to avoid the dangers of damage or injury arising from the scissors-like actionof these other supports and the objections due to the need for extra elbow room for said supports in folding. V

Another important object consists in providing a telescoping type support employing a'rotary action between the pin and slot means for releasably locking the telescoping members in extended operative position, an endlessslot orchannel being provided directly in' or on one of the telescoping members andthe cooperating pin on the other and provision being made for relative rotation either directly betweenthe telescoping members themselves or' parts carried thereon as required in the locking and unlocking of the members in operation. it

Still another object consists in the provision of a telescoping type support of the character described having provision for releasably locking the telescoping members either in an extreme extended relation or at one or more intermediate points to suit the convenience of the operator.

The invention is illustrated in the accompanying drawings, wherein .Figure 1 is a vertical sectional detail through a portion of the luggage compartment onthe rear of an automobile, showing a telescoping support made in accordance with my invention," applied to the lid or door thereof, the lid being also indicated in dotted lines to show how the support functions;

Similar reference numerals are applied to corresponding parts throughout the views.

Referring first to Figs. 1 to 5, the numeral ll designates the rear trunk or luggage compartment on an automobile, and I2 its'lid or door hinged at 13 to permit raising and lowering the same, as indicated in the full and dotted line positions. l4 andl5 are two supporting arms or links pivotally attached at l6 and I 1, respectively, to the side wall of the trunk II and edge portion ofuthe' lid l2, as, shown. The arms [4 and I5 in accordance with my invention, are in slidable telescoping relation, and in the closed position of the lid are telescoped substantially their full length, as shown in full lines in Fig. 1, thus taking'up a minimum amount of space inside the trunk, a small fraction of that required with folding, supports. The" arm I5 is tubular and fits over the rod forming the arm I 4, and these parts are arranged to be'locked releasably in extended relationship by'means of a pin IS on the rod l4 working in the slot IS in the tube 15. The tube I5 is held against turning by the pivot pin ll relative to the bracket 20,

but the rod I4 is annularly grooved .at its lower end, as shown atZl, for universaLswivel, and pivotal movement with respect to the bracket 22, so that the pin I8 can follow the bends and turns of the slot Hi. The rod I 4 makes one complete turn in each cycle of movement of thepin 18 from its starting point in 'the slot l9 where it is shown in Fig. 2. The slotl9 is of W formation, generally speaking, one branch- {Z of the W extending longitudinally and connecting with the other branch b of the W at c; d andd are two crotches in longitudinally spaced relation formed by the inverted Vs interconnecting the lower ends of the branches a and b' of 'the W. e "is a shoulder or ledge provided at an intermediate point of the length of thebranch o preferably at about the middle to serve as an intermediate point of support on the way to the points d and d where the pin l8 can engage to releasably' lock the telescoping parts in partly extended relation.

Most of the branch b is formed'by an extruded channel-shaped portion 23 formed in the wall of the tube I5, it being obvious that this connecting web portion notonly adds strength, but alsopermits of the double W slotformation, with two points (1 and d either of which may be engaged by the pin 18. A treble or quadruple W formation is, of course, permissible with this construc-. tion,'but theprovisionof one or more intermadiate supporting shoulders e make it unnecessary.

to provide any additional supports at d and d.

In the actual manufacture of the present supsubstantially the form shown in Fig. and then formed around an arbor .to the tubular form.

In operation, when the lid is closed, the pin I8 is in the position shown in Fig. 2 'near the ex- 5 treme upper end of the branch or. of the w slot 19. When the lid is raised part way, the pin l8 moving the branch a makes a slight jog at the point e so that the pin is in line with the supporting shoulder and the operator may, if he so desires, release the lid and it will be supported in the intermediate position. This makes it convenient for him to change his grip on the lid in such a way as to make it easier for him to lift the lid the rest of the way to the extreme raised position when the pin is engages in thecrotoh I. When the lid has been raised as far as it will go and the operator then releases it, the pin i8 rides into the crotch d, thus releasably locking the telescoping parts in extended lid-supporting relation. If the operator happens to be of small stature or happens to be standing on a low level so that it is inconvenient or awkward for him to raise the lid as far as it will go, he can nevertheless lock the lid in an intermediate raised position so long'as the pin l8 reaches the point g where there is a slight jog in the slot l9 just below the crotchd, the pin 18 under those circumstances being sure to engage in the crotch d. When the lid is to be lowered again, the operator merely raises it enough to cause the pin I8 to ride into the crotch h, assuming that the pin was engaged in the crotch d, whereupon the pin l8 will follow the branch I) back to the upper end of branch a, through-the channeled portion 23 of the tube l5. If the pin l8 happens to be engaged in the crotch d, it is obvious that the lid need be raised only enough to bring the pin into the lower end of the channeled portion 23 of the branch b, whereupon the lid may be lowered to 40 closed position. In the operation described, the rod l4 turns with so little frictional resistance that it is not noticeable, and, of course, in the assembling of the support, graphite or' hard grease can be applied to the rod l4 to insure easy 45 operation and ample lubrication of all parts of the W slot I 9 for easy riding of the pin 3 therein.

The support illustrated in Figs. 6 to 8 comprises a similar rod l4 and tube l5, the tube beingpivotally connected to a bracket 20', as at 50 H, and the rod being universally swivelled in a bracket'22, as at I6. A pin IS on the rod l4 works in a slot l9 in the tube l5. The slot i9 is of simplified w formation having simply the two branches a and b interconnected, as at c,

55 at their upper ends and extending from opposite sides of the single inverted V formation defining the crotch d. 23' is an extruded channel formation integral with the wall of the tube 15, as in the other support. A support constructed along 60 these lines is entirely satisfactory for support of a hood like that shown at 24 in Fig. 6, where the bracket 20 is fastened to the inside of the hood and the bracket 22' is fastened to the dash 25. For this purpose, the rod and tube parts can 65 be much shorter than in the case of a lid support, and usually also of smaller cross-section, since the hoods are ordinarily much lighter than the lids. Of course, supports of both types herein illustrated may be provided for either purpose;

70 that is to say, the support shown in Figs. 1 to 5 is not necessarily limited to use as a lid support, nor is the support shown in Figs. 6 to 8 limited to use as a hood support.

A further modification is shown in Fig. 9 where the rod Ma cooperates with the tube 15a similarly as in either of the forms previously described, and the bracket 20a has the tube [511 pivoted thereto, as at Ila. However, the bracket 22a in this form has a tube 26 pivoted thereto, as at 27, and the lower end of the rod I la, is swivelled, as indicated at 28. With this construction there is less play between the rod and its supporting bracket and accordingly less likelihood of the support rattling when the car is in motion.

A still further modification shown in Fig. 10 comprises a rod Mb and tube l5b in which the rod is pivoted at itslower end in a bracket 22b as at 29, while the tube 15b is pivoted in a bracket 20?), as at I117. The pin l8b in this case is carried on a sleeve 30 which turns freely on a reduced upper end portion 3| of the rod Mb. The sleeve is suitably retained by a washer 32 fitting on the upper end of the reduced portion 3| which is suitably turned down slightly to provide a shoulder for support of the washer and has its protruding end upset, as at 33, to retain the washer permanently. This construction, like the construction of Fig. 9, avoids any need for much play between the parts and accordingly eliminates likelihood of the support rattling when the car is in motion.
