1 Claim.
This invention relates to a ladder, and more particularly to a ladder adapted'to be usedon a vehicle, such 'asa truck.
The object of the invention is to provide a nader that can be easily attached to the body of a vehicle, such as .a truck, and wherein the ladder can be swung out 'of the way when not being used, or swung to an operative position when a persondesires to use the :ladder "to .gain access to the truck.
Another object of the invention is to provide a ladder for a truck which can be readily moved out of the way when not in use and maintained in this out-of-the-way position, or the ladder can be swung to an operative position as desired.
A further object of the invention is to provide a ladder which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this application, and in which like numerals have been used to designate like parts through out the same:
Figure 1 is a fragmentary, rear elevational view of a truck showing the ladder assembly of the present invention in its operative position;
Figure 2 is a sectional view taken on the line 2-2 of Figure 1;
Figure 3 is a sectional view taken on the line 33 of Figure 1;
Figure 4 is a sectional view taken on the line 4-4 of Figure 1;
Figure 5 is an enlarged sectional view taken on the line 5-5 of Figure 2.
Referring in detail to the drawings, the numeral l designates a portion of a vehicle, such as a truck, and the truck includes a bed I I, there being a housing or body [2 supported on the truck II. The truck I0 is further provided with the usual ground-engaging wheels I 3.
The present invention is directed to a ladder I 4 which, when in its operative position as shown in solid lines in Figure 1, enables a person to gain access to the housing l2, and when the ladder I4 is not being used, the ladder can be swung to the position shown by broken lines in Figure 1. The ladder M includes a pair of spaced parallel legs I and I6, and extending between the legs and i6 and secured thereto is a plurality of spaced parallel steps I1.
One end of the legs I5 is shaped to define an ofiset or transverse bearing am Hi, while the corresponding end of the other leg 16 is shaped to define a bearing arm 20. A swivel mounting l9 2 serves to :pivotally connect the bearing arm 18 to the truck bed I-l, wherebythe ladder 14 can be swung into and out of itsoperative -position.
The swivel mounting I29 includes a support member 2!, and :a bolt -22 projects through an opening 23, Figure .5, .in the flat portion of the support member 2|, the bolt 22 also extending through .a :registering opening :25 inthe truck :bed II. A nut '24 is arranged in threaded engage ment "with one end of the :bolt 22, and the bolt 22 provides :a pivotal connection between the truck bed II and the support member 2|. A bushing 26 is circumposed on the bolt 22, and a washer 21 is also circumposed on the bolt 22, whereby the support member 2| will be able to pivot about a horizontal axis in a smooth and eflicient manner and without any binding of the parts. The bearing arm 18 extends through a suitable opening in the support member 2 I, and a cotter pin 28 is arranged in engagement with the free end of the bearing arm l8 for maintaining the bearing arm [8 connected to or assembled to the support member 2 I.
Spaced from the swivel mounting I9 is a first bracket 29, Figure 3, and the bracket 29 is secured to the truck bed by suitable securing elements, such as bolt-and-nut assemblies 3|. The bracket 29 includes a lower, arcuate portion or web 30 which is adapted to receive therein the bearing arm 20, so that the ladder M can be supported or maintained in its operative position when a person desires to gain access to the interior of the truck.
A pair of spaced bumpers 32 are also secured to the truck bed I I by suitable securing elements, such as bolt-and-nut assemblies 33, Figures 1 and 2, and the bumpers 32 are adapted to be engaged by the legs 15 and l 6 of the ladder when the ladder is being used, in order to maintain the ladder spaced at a. sufilcient distance from the truck bed.
A second bracket 34 is secured to the rear end of the housing l2 by suitable securing elements, such as bolt-and-nut assemblies 35, Figures 1 and 3, and the bracket 34 includes a web or arcuate portion 36 for at times receiving therein the leg N5 of the ladder l4. Thus, when the ladder I4 is not being used, the ladder M can be swung from the solid line position of Figure 1 to the broken line position of Figure 1, and the leg 16 can be engaged or arranged in the web 36, whereby the ladder will be maintained in its out-of-the-way position until needed.
out of an operative position. When the user desires to gain access to the housing I 2 on the truck III, the ladder H is swung to the solid line position shown in Figure 1. Then, the user can merely gain access to the housing l2 by placing the feet on the steps ll. It will be noted that when the ladder I4 is in its operative position, the bearing arm 20 is supported by the web 30 of the bracket 29. Then, when the ladder II is not being used, the ladder can be swung to an out-oI-the-way position which is indicated by broken lines in Figure 1. Thus, the leg II; will be received in or engaged in the web 36 of the bracket 35 so that the ladder H will be maintained against the rear of the housing I2, whereby accidental movement or the ladder will be prevented. The support member 2| is pivotally connected to the truck bed II by the bolt 22, and also, the bearing arm 18 is rotatably arranged in the support member 2 I.
The assembly of the present invention is extremely simple and inexpensive to manufacture. The parts of the ladder can be constructed of pipe if desired. Also, by removing the cotter pin 28 from the bearing arm I8, the entire ladder ll can be removed from the truck if desired.
I claim:
In combination, a truck including a bed, and a housing supported on said bed, a ladder including a pair of spaced parallel legs, and a plurality of spaced parallel steps extending between said legs and secured thereto, one end of each of said legs being arranged transversely with respect to the main portion of the leg to define a bearing arm, a swivel mounting for pivotally connecting one of said bearing arms to said truck bed, a bracket spaced from said swivel mounting and secured to said truck bed for engagement with the other bearing arm when the ladder is being used, bumpers secured to said truck bed for engagement with said legs when the ladder is in operative position, and a bracket secured to said housing for supporting the ladder when the ladder is not being used.
