Description

D. J. LlPSKl JACK STAND April 20, 1948.
Filed April 25, 1946 l m S on Y wm J 0 JW n I' Am 3 L m n C.. D
Patented Apr. 20, 1948 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to adjustable supports for motor vehicles and the like.
One object of the present invention is to provide a vertically adjustable support having a selflocking pin for securely retaining the same in any selected position of adjustment.
Oth'er more specific objects and advantages will appear, expressed or implied, from the following description of an illustrative embodiment of this invention.
In the accompanying drawing:
Figure 1 is a view in elevation of a support constructed in accordance with the present inven tion.
Fig. 2 is a horizontal sectional view taken along the line 2-2 of Fig. 1.
Fig. 3 is a perspective view ol' the locking pin shown in the other views.
The support selected for illustration comprises a telescopic standard mounted on a suitable base I0. In this instance th'e standard includes a tubular portion II welded or otherwise xed to the base plate I 8 and a cooperating plunger I2 guided for free lengthwise adjustment in the tubular portion. A saddle I3 fixed to the upper end of the plunger I2 provides a convenient seat for the vehicle or other part to be supported thereby.
Th'e standard is rigidly sustained in upright position by suitable braces I4 welded thereto and to the base plate Ill. 'I'he several corners of the base plate Ill are preferably bent downwardly, as at I5, to provide a secure non-skid engagement with the surface on which it rests.
The plunger I2 is releasably retained in various positions of vertical adjustment in the tubular portion II by a pin I6 adapted to extend through the tubular portion and th'rough any of the longitudinal series of transverse holes II in the plunger I 2, suitable means being provided for automatically locking the pin I8 against accidental displacement. A simple and effective means for this purpose will now be described.
In this instance the pin I6 is shown equipped with an olset angular formation I8 adapted to swing by gravity into a position where it atleast partially embraces th'e standard Il when the pin I6 has been projected through the standard II. The formation I8 includes [at one end a supporting arm I9, which extends laterally from one end of the pin I6, and also includes at its other end an angularly disposed linger 2U permanently olfset laterally from the other end of the pin I E. This formation I8 is preferably formed integral with' the pin I6 and swingable about the axis of the pin.
'I'he arrangement is such that with the formation I8 swung into the dotted line position shown in Fig. 1, with the locking linger 20 elevated to clear the standard II, the pin I6 may be readily inserted and projected through' the standard and plunger I2 to position the latter therein. Thereafter, the formation I8 may swing by gravity into` the full line position shown, thereby causing the finger 28 to automatically assume a position behind the standard II where it coacts with th'e standard to prevent accidental withdrawal of the pin. It will also be noted that, since the formation I8 and pin 20 cannot assume this lower locking position unless and until the pin I6 has been projected completely through the standard II, it serves as a visual check by which accidental partial entry of the pin may be avoided.
In order to avoid loss the pin I6 is preferably permanently connected to the support by suitable means such as a chain 2 I.
Various changes may be made in the support hereinabove specifically described with'out departing from or sacriiicing the advantages of the invention as defined in the appended claims.
I claim:
l. A locking pin for supports of a type having a vertically adjustable telescopic standard, said pin having a body portion projectable through the standard to secure the same in various positions of adjustment, and a gravity urged angular formation carried by said pin and swingable about the axis of the latter into interlocking relation with th'e standard to ret-ain said pin against accidental withdrawal. r
2. A locking pin for supports of a type having a vertically adjustable telescopic standard, said pin having a body portion projectable through the standard to secure the same in various positions of adjustment, and an angular formation for embracing the standard to retain said pin against accidental withdrawl, said formation being connected to one end of said pin and terminating in a ringer extending transversely of said pin and laterally spaced from the other end of said pin.
3. A locking pin for supports of a type having a vertically adjustable telescopic stan-dard, said pin having a body portion projectable 'through the standard to secure the same in various positions of adjustment, and a pin retainer structure rigidly connected to `one end of said pin and swingable by gravity into pin retaining position, said structure terminating in a linger disposed cross-wise of said pin spaced lfrom but `adjacent the opposite end of said pin.
