z, I INVENTORS la "fl l8 DONALD B. DOCHERTY PAUL L. DANNER FIG. 4 9H4 BACKGROUND OF THE INVENTION It has heretofore been known to provide a singular furniture-or product-carrying device that has a portion engaging the vertical side of the product to be carried and a portion that underlies the product to be carried. For example, U. S. Pat. No. 2 I 8,865 shows a device utilizing such features. Also, it has heretofore been known to provide furniture-carrying devices that utilize wheels so that once the device is placed under the furniture, the weight of the furniture can be supported on the wheels.

When carrying bulky furniture such as television sets, washing machines, dryers, pianos and other types of bulky furniture, the problem is not so much the weight of the product as much as the ability to grip the product easily and particularly when picking up the product. Thus, when carrying a large television set by two men, the problem is not the weight of the set as much as the ability to grip the set for carrying.

SUMMARY OF THE INVENTION With the above in mind, it is the primary object of the present invention to provide a productor furniturecarrying device that is a single rigid device composed of a pair of L-shaped members having a vertical leg portion that bears against the vertical side of the product and a lower horizontally extending leg portion that bears against the under side of the product. The two L- shaped members are rigidly joined by a singular cross member that is supported on the vertical leg portions in rearward spaced relation from the facing side of the members so that the cross member may be gripped and carried.

More specifically, it is the object of the present invention to provide the cross member of the abovedescribed type that is detachably but rigidly connected to the pair of L-shaped members. Thus, the two L- shaped members may be spaced apart at desired distances by using different lengths of cross members. For example, it may be desirable to have a comparatively narrow device for carrying the ends of a piano as compared to that desired to carry washing machines. Consequently, in one form of the invention, it is necessary only to interchange longer or shorter cross members in accordance with the spacing desired to be had between the L-shaped members. In a second form of the invention, the cross member or handle has a series of openings through which bolts extend and connect to the L- shaped members. In this way, a single cross member may be utilized to provide a device having various spacings between the L-shaped members merely by adjusting the effective length of the cross piece between the members.

It is still a further object of the present invention to provide with the above carrying device a pair of detachable wheel assemblies- Each wheel assembly is composed of a base member that lies adjacent the underside of the horizontal leg portions of the L-shaped member and has a pair of bail members rigid with the plate and that overlie the horizontal leg portions, with one of the bail members lying closely adjacent the vertical leg portions and having brackets or ears extending to the rear side of the vertical portions. A detachable element or bolt extends between the ears and when inserted and attached thereto holds the base plate on the horizontal portion. The base plate carries a depending swivel-type or castor-type wheel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 4 is a sectional view taken substantially along the line 4-4 of FIG. 2.

FIG. 5 is an enlarged sectional view through the lower portion of the L-shaped member and with the wheel attachment mounted thereon.

FIG. 6 is a rear perspective view of the device showing a modified form thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT The fumitureor product-carrying device is composed of a pair of upright rigid L-shaped members 10, 11 disposed parallel to one another and having

upright portions

12, 13 and generally

horizontal portions

14, 15 that project forwardly from the lower ends of the vertical portions I2, 13. The vertical portions l2, 13 are U-shaped channels providing forward flanges or

coplanar portions

16, 17 bearing against a vertical side of the fumiture or product to be carried. The

portions

14, 15 have upper surfaces that are coplanar to one another but which are at a slight acute angle a to the

portions

16, 17. In the preferred form, the acute angle a is substantially 85 although a slightly lesser or greater angle will operate to substantially some advantage. A preferred range is between and 89. The acute angle is desired so that the weight of the product to be carried will be utilized to draw the vertical side of the product against the vertical portions l2, l3 and to operate to retain the engagement between the portions and the vertical side of the product.

The height of the

vertical portions

12, 13 is 16 inches and again a range of 12-20 inches would be desirable in order that the device be light enough and yet manually controllable enough for a single person operating from a side of a rather heavy product to be carried. The

horizontal portions

14, 15, besides having the acute angle a, also are tapered from a relatively thick heel portion to a relatively narrow forward or front tip portion. By so tapering the portions l4, 15, they may easily be inserted under a low-lying piece of furniture. 7 Bonded to the horizontal portions '14, 15 on all sides thereof and to the front faces and sides of the

vertical portions

12, 13 is a layer of elastomer material 18. The layer 18 serves the purpose of preventing scratching or damaging of the product that is being carried as well as a frictional surface which aids in retaining the product on the device.

A pair of

rigid brackets

19, 20 are welded to the rear surfaces of the

vertical flanges

17, 18 and extend rearwardly therefrom. The cars or

brackets

19, 20 have U shaped recesses or

notches

21, 22 cut out of their rear ends. A cross piece or handle 23 extends between and connects to the

brackets

19, 20. The handle 23 has U-

shaped ends

24, 25 that seat in the

recessed notches

21, 22. A tapped opening is provided in each of the

brackets

19, 20 that receives bolts 26 that extend through the i to 6 inches from the top of the upright portions.

Wheel attachments 30 are each composed of a base or plate 31 that underlies the respective

horizontal portions

14, 15. Fixed to the plate 31 is a castor 32 that carries the wheel 33. Rigid with the plate is a first or tip bail 34 that extends over the tip of the horizontal portion 14 or and a second bail 35 that fits over the

portions

14, 15 adjacent the heel end or closely adjacent the respective

vertical portions

12 or 13. The bail 35 has a portion that fits against both the

horizontal portion

14 or 15 and the

vertical portion

12 or 13. The bail 35 also has a pair of rearwardly projecting

brackets

36, 37 that extends to rear ends behind or rearwardly of the respective

vertical portions

12, 13. A bolt 38 that is detachable from the ears or

brackets

36, 37 extends between the ears and behind the vertical portions l2, l3 and serves as means for retaining the wheel device on the L-shaped member.

When mounting the wheel devices on the L-shaped members 10, 11, the

bails

34, 35 are slid over the

horizontal portions

14 or 15 and until the cros piece of the second bail engages the

vertical member

13 or 14. The bolt 38 is then inserted and the wheel device is retained on the respective member.

Referring now to FIG. 6, there is provided a handle or cross piece 40 that has

opposite ends

41, 42 that are U-shaped in cross section and may be received in the

notches

21, 22. The

ends

41, 42 have a series of longitudinally spaced

openings

43, 44 respectively that receive the bolts at 26. Therefore, as is clearly apparent from viewing FIG. 6, the spacing between the members 10, 11 may be adjusted by inserting the bolts 26 into the desired

openings

43, 44 and tightening the bolts in the tapped openings in the

brackets

19, 20.
