Abstract
FOLDABLE HITCH
ABSTRACT OF THE DISCLOSURE
Hitches for trucks and the like are difficult to store and usually have to be detached when not in use. The present hitch includes a pair of telescopic arms pivotally connected to attachment brackets under a bumper, spaced apart from one another and when in use, converging forward-ly to a common apex and being detachably secured in this position. One arm is provided with a hitch clevis on the distal end thereof. The telescopic construction of the arms assists in connecting the hitch clevis to the device being towed such as an implement, trailer or the like.
When stored, the two arms are disconnected at the apex and are folded under the bumper in side by side relation-ship and held by a detachable pin until required.

Description
'7 FOLDABLE HITCH
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in foldable hitches, particularly hitches adapted to be used with the bumper of such vehicles as trucks and the like. Such hitch assemblies are difficult to store when not ;n use and are usually detached and stored separately.
Such hitches which are usually tr;angular when viewed in plan, are also difficult to engage with the hitch pole of the device being towed which is usually a far~ implement or the like.
SUMMARY OF THE INVENTION
: The present invention overcomes.these disadvanta-ges by providing firstly, a hitch assembly which is eas;ly stored under the bumper when not in use and secondly, when extended for use, is easily aligned and attached to the hitch pole of the farm implement being secured to the hitch.
and in accordance with the invention, there is provided a hitch assembly for securement to a vehicle bumper comprising ~20 in combination a main telescopic~hitch arm and a secondary telescopic h;tch arm, means p;votally secur;ng each arm~by the ;nner end thereof to sa;d buinp:er in spaced apart rela-tionship for pivoting in a horizontal plane, a hitch clevis :
. . , . ' ' .
~ 2 secured to the outer end of said main hitch arm, means co-operating between the outer end of said secondary hitch arm to detachably secure same to adjacent the outer end of said main hitch arm thereby forming a substantially tr;angular hitch configuration when viewed in plan and means to store said arms in side by side relationship under the associated vehicle bumper, when not in use.
Another advantage of the present invention is that it is easily stored under the bumper when not in use.
A still further advantage of the invention is that it is easily attached to bumpers of trucks and the like with the mlnimum of effort.
A still further advantage o~ the invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture and otherwise well suited to the purpose for which it is design-ed.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompany- ;
- ing drawings forming a part hereof, which includes a des-cription of the preferred typical;embodiments of the princi-ples of the present invention, ;n which:

DETAILED DESCRIPTION

The main hitch arm includes the inner portion 14 thereof which is preferably formed from hollow square cross sectioned tubing and an outer section 15 which is also pre-ferably formed from Kollow cross sectioned tubing and is telescopically engaged with the inner section 14 thereof.
This telescopic relationship of the two sections 1~ and 15 is adjustable and controlled by d: spring loaded lock bolt assembly 16 passing through plate 17 secured to the side of the tube 14 and extending through the wall of the tube to engage through the wall of the outer tube 15 and into an aperture in the wall of the outer section 15 when fully extended.
The secondary hitch arm is also telescopic and includes the inner section 18, and the outer section 19 telescop;cally engaging therein in a manner and configura- ;
tion similar to the main hitch arm assembly 12 with a spring loaded locking bolt 16 engaging plate 17 in a manner similar to that hereinbefore described and securing the two sec-tions 18 and 19 in the extended position one with t~he other.

However~ it will be appreciated that other forms of pivotal attachment to the bumper may be utilized al~ways providlng that sufficient strength is incorporated in the design and that the two tele-scopic arms 12 and 13 may pivot relative to the bumper in a horizontal plane and, desirably, that one arm 13 can rotate through 180 for storage as will hereinafter be described.
. 10 The main hitch arm 12 also includes a hitch cle-vis assembly collec:tively designated 25 on the outer end 26 of the section 15 and this hitch clevis assembly inclu-des a pair of spaced and parallel horizontally situated plates 27 extending at an angle from the end 26 and being apertured to receive the correspondingly apertured outer end 28 of the secondary arm 13. A detachable anyulated pin 29 engages through the aligned apertures and holds the two hitch arms 12 and 13 together at the common apex form-- ed by the hitch clevis 25 thus providing a substantially triangular configuration when viewed in plan as shown in ; Figure 1.
The hitch clevis assembly 25 also includes the main spaced and parallel horizontally situated clevis pla-tes 30 whi~h may engage over ehe distal end 31 of an imple-, .

When in the position illustrated in Figure 1, the hitch clevis 25 may be aligned with the hitch pole 32 by releasing the lock bolts 16 of the arms 12 and 13 so that the telescopic relationship of the two arms may be varied manually in order to assist in positioning the clevis over the end 31 of the hitch pole whereupon the pin 33 may be dropped into place. The truck is then driven forwardly thus equalizing the arms and fully extending same where-upon the spring loaded lock bolts automatically engage the outer sectiQns.
When it is desired to store the hitch assembly, the pin 33 is removed thus disconnecting the hitch pole 32. The p1n 29 is next removed disconnecting arm 13 from arm 12 whereupon bolt 16 lS released so that section 19 of arm 13 may be fully retracted.
This secondary arm is then swung inwardly parallel to and iust under bumper 10 and rotated.

The secondary arm is then rotated through 180 thus folding it behind the bracket 24 and sub-stantially parallel to the bumper. In this position, an apertured lug 34, extending from the underside of the sec-tion 14 adjacent the inner end thereof, may slide under the apertured outer end 28 of the section 19 of the second-ary arm 13 whereupon the pin 29 may engage through the apertured outer end 28 and through the apertured lug 34 thus detachably securing the two hitch arms together in side by side relationship just under the bumper 10 until again required.
Figures 7 and 8 show the automatic action oE the locking assembly with the spring loaded pin or bolt 16 en gaging behind the inner end 37 of the arm or tube 15 when fully locked.
Figure 8 shows the pin 16 lifted agains~ the spring pressure of spring 38 so that t'ne arm portion 15 can be retracted reLative to the arm portion 14. A guide tube 37A is welded to the end of arm portions 14. When ex-tended towards the locked position, the inner end 16A of the pin 16 rides up the ramp 36 situated on the inner end 37 of arm 15 thus allowing the arm to extend fully with the pin automatically engaging behind the inner end of the arm as clearly shown in Figure 7.
