LADDER SUPPORT Filed Oct. 25. 1955 67mm 5: 5f IVEVRA INVENT OR ATTORNEY United States Patent LADDER SUPPORT Charles S. Neyra, Dallas, Tex.

Application October 23, 1953, Serial No. 387,961

7 Claims. (Cl. 214-450) This invention relates to ladder carriers and more particularly to apparatus for supporting and carrying ladders on trucks.

Heretofore, tradesmen whose work requires them to employ ladders for reaching high places, such as roofs of houses and the like, have found it necessary to send two workmen on jobs which would ordinarily require the services of but one were it not for the removal of a heavy ladder from its mounting on the top of a truck and its replacement which requires effort usually too strenuous for a single workman.

It is, therefore, the principal object of the invention to provide a ladder carrier for trucks so designed and constructed that a single workman, without undue effort may remove a heavy ladder from the top of a truck and replace the same without manual assistance.

Another object of the invention is to provide a ladder carrier of inexpensive construction which is easily secured to the top of a vehicle such as a panel truck.

Broadly, the invention is comprised of a pair of mounting members supported in spaced apart relationship transversely on the top of a truck, each mounting member consisting of a stationary lower section and an upper section parallel with and movable longitudinally with respect to the lower section and provided with a hinge enabling the movable upper section, which supports the ladder, to be moved to a position where it will be parallel with the side of the truck and thus dispose the ladder supported on the movable sections in a position to be easily lifted from the carrier and as easily replaced thereon for restoring it to its original position atop the truck.

Other objects will become 'manifest as the description proceeds when considered with the annexed drawing wherein:

Figure 1 is a fragmentary side elevational view of a truck, in dotted lines, showing the invention mounted thereon.

Figure 2 is a fragmentary end elevation of the truck, in dotted lines, showing a side view of one of the two identical ladder supports of the invention.

Figure 3 shows the invention in a position to present the ladder for removal from the carrier.

Figure 4 is a transverse sectional view taken on line 44 of Figure 2, and I Figure 5 is an expanded view in perspective of related parts of the latch at one end of each supporting assembly for holding the sections thereof against relative displacement.

Continuing with a more detailed description of the drawing, reference numeral denotes generally each of the complementary supporting assemblies constituting the ladder carrier and which are of identical construction, hence corresponding parts will carry identical reference numerals.

While the drawing shows two of the supporting assemblies, it is evident that more than two may be employed, if necessary or desirable, and each of the supporting assemblies is comprised of a rail 11 of wood or metal which ice may be secured transversely across the top of a truck T by the usual means consisting of a rubber suction cup 12 and anchoring straps 13 having hooks 14 on their ends engaging under the drain channel 15 skirting the top of the truck.

Secured to the rail 11 by screws or other suitable means 16 is an inverted channel member 17 having a longitudinal slot 18 in its web 19 terminating short of its ends. The above described elements constitute what is referred to as the lower or stationary section of the carrier.

Disposed above the channel member 17 is a comple mentary channel member 20. The channel member 20 has a short tail portion or section 21 of the same crosssectional shape as the member 20 but has mounted therein on transverse shafts 22 a pair of rollers 23 which roll upon the web 19 of the channel member 17 of the lower section. The channel member 20 is connected to the channel member 17 through the medium of the tail section21 by means of an inverted T-shaped lug 24, as shown in Figure 4 so afiixed to the undersurface of the tail section 21 that its leg will extend downwardly through the slot 18 in the web of the channel member. The bar 25 of the lug 24 slidably underlies the web 19 and prevents movement of the tail portion 21 except in a longitudinal direction.

The tail portion 21 of the upper section of the support is attached by means of a hinge 26 to an adjacent end of the channel member 20, the plates of the hinge 26 being secured to filler blocks 27 which are aflixed in adjacent ends of

members

20 and 21.

It is evident from the foregoing that the upper section of the support, composed of

members

20 and 21, may be moved freely along the top of the lower section or channel member 17, also, that when the hinged end of the upper section rides off the end of the lower section, it will drop down to a position at right angles to the stationary upper section, as shown in Figure 3.

Affixed perpendicularly to the midsection of the channel member 20 is a pair of spaced apart studs 28, on the outside of each of which rests a leg 29 of a ladder 30 which ladder extends across and is supported by both of the supports 10. Rotatably mounted on each stud 28 is an arm 31 which in operative position extends outwardly and is biased against a leg of the ladder by a compression spring 32 surrounding the stud 28, bearing at one end against the arm 31 and at its opposite end against a head 33 on the stud. A collar 34 on the stud below the arm 31 limits longitudinal displacement of the arm on the stud. In this manner the ladder 30 is held on; the carrier whether atop the truck or in the position shown in Figure 3. It requires only rotation of the arms to an inner position to free the ladder for removal from the carrier or for its replacement thereon.

In Figure 5 is shown details of' the latching means by which the upper section is held against displacement from its position atop the stationary lower section. This structure consists of a block 35 secured within the free end of channel member 20 and to this block is secured, by means of screws 36 a plate 37 having side flanges 38 and an inner end flange 39. The ends 40 of the side flanges 38 are outwardly divergent and the end flange 45 downwardly turned, serving as a guide when the upper section of the carrier is moved from the extended position shown in Figure 3 to the position shown in Figures 1 and 2, the flared portions of the plate directing the free end of the member 20 onto the outer end of member 17. When positioned atop member 17, the upper section is secured thereto by means of a pin 41 which is thrust through holes 42 (Figure 5) in flanges 38 of plate 37, through a hole 43 in a flange 44 of an end plate 45 and through a matching hole 46 bored through a block 47 which is secured to an end of the member 17 by a reduced extension 48 of the block entering the end of the member 17 and secured thereto and to the rail 11 by screws 49.

The pin 41 has an annular groove 50 adjacent its free end and when the pin is inserted through the matched holes described, the groove 50 receives an edge of the hole 43 in the angular flange 44 of the end plate 45, which is made of spring steel. This holds the pin 41 against release from latching position until the flange 44 is pressed down to align the holes, whereupon the pin can be freely moved. A short length of chain 51 serves to connect the pin 41 with the member 20 to prevent loss or misplacement.

It is evident from the foregoing, without need for a description of function, that a single workman grasping a leg of the ladder 30 at a point midway between the two supports may, with little effort, lower the ladder to the position shown in Figure 3 where it can be lifted easily from the supports and as easily replaced. After its replacement, the ladder is pushed up to a position atop the truck, guiding the free ends of the top sections onto the adjacent ends of the bottom sections 17 by the flanges 38-39 on plate 37. When in position, the pin 50 is inserted to secure the sections one to the other.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
