Application October 5, 1953, Serial No. 384,289

2 Claims. (Cl. 280--35) which can be moved to inoperative position lying closely adjacent the suitcase.

A further object of this invention is to provide a baggage dolly having means for securing the same to a suitcase or the like, which means is adjustable to accommodate pieces of luggage of various sizes.

A further object of this invention is to provide a baggage dolly having a leg supporting a wheel, which leg is extensible so as to position the piece of baggage supported by the dolly at a convenient height for the user.

A still further object of the invention is to provide a baggage dolly which is simple and eflicient in construction and durable and lasting in use.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view showing the baggage dolly forming the subject of this invention attached to a piece of luggage;

Figure 2 is a sectional view taken substantially along section line 2--2 of Figure 3;

Figure 3 is a view partly in section of the leg for supporting the piece of luggage;

Figure 4 is a sectional view showing the leg in collapsed position;

Figure 5 is a perspective view of the baggage dolly forming the subject of this invention; and

Figure 6 is a sectional view taken substantially along section line 66 of Figure 5.

Referring now more specifically to the accompanying drawings, it will be seen that the improved baggage dolly forming the subject of this invention includes, as shown in Figure l, a base 10 having a strap 12 secured thereto and adapted to be extended around a piece of luggage 14.

As seen in Figures 5 and 6, the base 10 consists of a horizontal, rectangular plate member 16 having a pair of T-shaped plate members 18 secured one at each end thereof. The T-shaped members 18 are positioned with the head portion thereof in a vertical direction and with the body portion thereof extending in a horizontal relation parallel to the plate 16. The upper edge of each T-shaped member 18 is provided with an aperture 20 which receives an end of the strap 12 for securing the same to the base 10. Each of the T-shaped members 18 is provided with a plurality of longitudinal slots 22 in the body portion thereof. A plurality of bolts 24 extend through the ends of the member 16 and through the slots 22. Thus, the width of the base 10 can be adjusted by loosening the bolts 24 and sliding the T-shaped members 18 away from each other. By tightening the bolts after such an adjustment, the T-shaped members 18 will be locked in fixed position.

The member 16 is provided with a pair of spaced downwardly extending cars 26 secured thereto adjacent the midpoint thereof. A hollow longitudinal member 28 is pivotally secured between the cars 26 by means of a pin .30. The member 28 is adapted to move in a direction transverse to the longitudinal axis of the member 16. A longitudinal member 32 of less diameter than the internal diameter of the member 28 is slidably received within the free end of the member 28. The member 28 is provided with a plurality of transverse apertures 34 spaced along the length thereof. The member 32 is provided with an aperture 36 adjacent the end thereof which is inserted in the member 28. A threaded pin 38 is adapted to be inserted through a selected one of the apertures 34 and the aperture 36 for retaining the member 32 in fixed position with relation to the member 28. A nut body 40 engages on the end of the pin 38 to retain the same in position. Thus, the length of the leg can be adjusted by removing the pin and sliding the member 32 inwardly or outwardly in the member 28 and then repositioning the pin 38 through aligned apertures.

The lower end of the member 32 is bifurcated, as at 42. A wheel 44 is disposed in the bifurcation and is rotatably mounted thereon.

Means are provided for retaining the leg in extended position. This means comprises a first member 46 hingedly secured at one end to the member 16 and with the pivotal connection thereof being spaced from the pivotal connection of the member 28 to the member 16. The member 48 is pivotally secured to the other end of the member 46 and also to the member 28. The hinge connection between the

members

46 and 48 is disposed on the sides of the

members

46 and 48 away from the pivotal connection of the member 28 to the member 16. Thus, the hinge connection will prevent the

members

46 and 48 from moving in a direction away from the pivotal connection of member 28 to the plate 16 after the

members

46 and 48 have become axially aligned.

The member 16 is provided with a spring clip 50 secured adjacent one edge thereof and extending downwardly therefrom. The spring clip 50 is substantially U-shaped and is positioned in alignment with the pivotal connection of the member 46 to the member 16 and the pivotal connection of the member 28 to the member 16. Thus, when the leg is collapsed, the member 28 will be received between the prongs of the spring clip 50 and be retained therein.

In practical use, the width of the base 10 is first adjusted to accommodate the desired piece of luggage. Then, the strap 12 is secured around the piece of luggage. Then, the leg is adjusted by sliding member 32 within the member 28 to achieve the desired height. When it is desired to transport the piece of luggage, the leg is placed in extended position. The wheel 44 is in contact with the ground and rolls thereon as the piece of luggage is moved. When it is desired to store the luggage, the leg is swung to inoperative position with the member 28 being retained by the spring clip 50. In this position, the dolly will rest upon the ground on the lower edges of the head portion of the T-shaped members 18.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described,

and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. In a baggage dolly, a base comprising a rectangular, horizontal baggage supporting plate member, a pair of T-shaped plate members slidably adjustably secured to the first named plate member at opposite ends of the first named plate member to vary the width of the base, said T-shaped plate members having vertical head portions confining baggage on the first named plate member and providing ground engaging rests for elevating the first named plate member and baggage thereon ofi the ground, a center leg for said base pivotally attached to the first named plate member between the second named plate members for swinging into vertical and horizontal positions, respectively, to raise the base off the ground and lower said head portions onto the ground, folding hinge means pivoted to said first named plate member and leg, respectively, for unfolding by swinging of said leg into vertical position to hold said leg vertical and foldable by swinging of the leg into horizontal position, and a terminal ground roller on said leg for rollably supporting said base.

2. The combination of claim 1, and a baggage securing strap secured to the upper edges of said head portions.
