Description

FIELD OF THE INVENTION

[0002] The present invention relates generally to transport vehicles for transporting furniture. More particularly the invention concerns a wheeled truck having a novel supporting structure that is connected to the base of the truck. Alternate forms of supporting structures are provided so that a particular supporting structure can be selected and affixed to the base to transport table tops, chairs of various configurations and like articles.

DISCUSSION OF THE PRIOR ART

[0003] Wheeled transport carts or trucks are old in the art and a wide variety of carts of various designs have been suggested in the past. Typically these transport carts comprise a flat platform to which a plurality of wheels or castors are rotatably connected. A handle of some type is connected to the platform to enable the cart to be pulled or pushed from place to place. While the prior art wheeled transport trucks are well-suited for carrying regularly shaped articles such as boxes, drums and like bulky articles, they are not well suited for transporting irregularly shaped articles such as chairs.

[0004] The extensive use of removable tables and chairs in a variety of public gathering places has presented a problem, namely how-to quickly and efficiently transfer the tables and chairs from auditoriums, meeting halls, large conference rooms and the like to remote storage areas. Attempts have been made in the past to use the prior art flat platform transport trucks for this purpose, but these trucks are not well suited because chairs and like irregularly shaped articles have a tendency to slide off the flat platform. Modifications to the prior art wheeled trucks are, therefore, needed to accomplish the transport of articles of furniture, such as chairs of various configurations. The thrust of the present invention is to provide such modifications to thereby provide a wheeled transport truck that is ideally suited for the safe transport of a variety of differently configured types of furniture.

[0005] The prior art chairs have taken on the number of different configurations, including conventional tubular frame chairs having four, ground-engaging legs and folding chairs of various designs. Special provisions must be made to safely and efficiently transport these types of chairs as well as folding chairs of various configurations. One of the objectives of the present invention is to provide a wheeled truck having a number of different types of carrying attachments for safely transporting chairs of various configurations, including conventional chairs as well as folding chairs.

[0006] As will be better understood from the discussion that follows, the unique design of the transport trucks of the present invention permits the safe and easy transport of differently configured tables and chairs from the auditorium or other place of use to the storage area. More particularly, one form of the novel transport cart of the invention comprises a base assembly to which variously configured support assemblies can be affixed. The variously configured support assemblies are specially designed to safely support table tops as well as chairs having conventional ground engaging legs and folding chairs of various designs.

SUMMARY OF THE INVENTION

[0007] It is an object of the present invention to provide an easy to use transport truck that can be safely used to move table tops, differently configured chairs in stacked arrays and other articles from one location to another.

[0008] It is another object of the invention to provide a transport truck of the character described which includes specially configured chair support track assemblies that are affixed to the base of the transport truck and can be readily interchanged as required.

[0009] Another object of the invention is to a provide transport truck of the character described in the preceding paragraphs which, by selecting one of several differently configured support assemblies, enables a truck of relatively standard design to be used to safely transport differently configured chairs.

[0010] Another object of the invention is to provide the transport truck for use in transporting table tops, chairs and like articles which is highly versatile, is of a sturdy, compact and light weight configuration and can be safely operated by a single workman.

[0011] Another object of the invention is to provide a transport truck of the class described that is durable, rugged in use, requires minimum maintenance and can be relatively inexpensively manufactured.

[0031] Referring to the drawings and particularly to FIGS. 1 through 5, one form of the transport truck of the present invention is there illustrated and generally designated by the numeral 24. Transport truck 24 is specially designed for transporting table tops of differing configurations which are disposed in a stacked relationship in a manner shown in FIG. 1. In this first embodiment of the invention, the transport truck comprises a base assembly 26 having transversely spaced-apart sides 28 and 30 and longitudinally spaced-apart ends 32 and 34 connected to and spanning sides 28 and 30. As best seen by referring to FIG. 2, base assembly 26 includes a longitudinally extending central support 35 and a plurality of spaced apart article support members 37. Ground engaging roller means, shown here as a plurality of ground engaging wheels 38, are connected to base assembly 26 in the manner shown in FIG. 4.

[0032] Provided at either end of the base assembly 26 is a generally vertically extending end support assembly 40. Each end support assembly 40 comprises a pair of generally vertically extending support members 42 which are connected proximate their lower ends to base assembly 26. To push or pull the transport truck along the ground, a push bar or handle assembly 44 is affixed to and spans support members 42 in the manner best seen in FIG. 1. Each handle assembly 44 includes a pair of generally cylindrically shaped hand grip portions 44a. Also forming a part of each end support assembly 40 is a transversely extending top member 45. Provided at each corner of the transport truck is a curved plate like article retaining member 47.

[0033] Connected to and spanning support assemblies 40 is a top assembly 46. Top assembly 46 includes a pair of transversely spaced apart, longitudinally extending beams 48. Connected to and spanning beams 48 are three cross members 50, 52 and 54. An angularly extending cross the brace 56 extends between cross members 52 and 54 and an angularly extending support brace 58 extends between cross members 52 and 54 so as to form a generally planar top support of the configuration best seen in FIG. 2.

[0034] Referring next to FIGS. 6 through 10, an alternate form of the transport truck of the present invention is there illustrated and generally designated by the numeral 64. Transport truck 64 is similar in construction to that shown in FIGS. 1 through 5 and like numerals are used to identify like components in FIGS. 6 through 10. Transport truck 64 is specially designed for transporting table tops of a lesser width than those shown in FIG. 1.

[0035] In this second embodiment of the invention, the transport truck comprises a base assembly 66, which is similar construction to base assembly 26 and includes transversely spaced-apart sides 28 and 30 and longitudinally spaced-apart ends 32 and 34 connected to and spanning sides 28 and 30. As best seen by referring to FIG. 7, base assembly 66 also includes a longitudinally extending central support 35 and a plurality of spaced apart article support members. However, these article support members, which are generally identified by the numeral 68, extend angularly downward from the sides of the base assembly toward central support 35. More specifically, each article support member or 68 includes a downwardly sloping central portion 68a and a generally vertically extending leg portion 68b which interconnects central portion 68a with a selected one of the side members 28 and 30. With this construction, when the more narrow table tops are disposed in a stacked relationship on the base assembly in the manner shown in FIG. 6 they tend to safely slope inwardly toward a central divider the character of which will put presently be described. Ground engaging wheels 38 are connected to base assembly 66 in the manner shown in FIG. 9.

[0036] Provided at either end of the base assembly 66 is a generally vertically extending end support assembly 40. Each end support assembly 40 comprises a pair of generally vertically extending support members 42 which are connected proximate their lower ends to base assembly 66. To push or pull the transport truck along the ground, a push bar or handle assembly 44 is affixed to and spans support members 42 in the manner best seen in FIG. 6. As before, each handle assembly 44 includes a pair of generally cylindrically shaped hand grip portions 44a. Also forming a part of each end support assembly 40 is a transversely extending top member 45. As in the earlier described embodiment of the invention, the transport truck is provided proximate each corner with a curved article retaining member 47.

[0037] Connected to and spanning support assemblies 40 is a top assembly 70. Top assembly 70 includes a single longitudinally extending beam 72 and a pair of angularly extending braces 74 disposed proximate either end of beam 72. Depending downwardly from beam 72 is the previously mentioned central divider assembly 76 which includes a central, generally vertically extending support 78 and a pair angularly extending support braces 80 and 82.(see FIG. 8).

[0038] Referring next to FIGS. 11 through 14, still another form of the transport truck of the present invention is there illustrated and generally designated by the numeral 94. Transport truck 94 is also similar and construction to that shown in FIGS. 1 through 5 and like numerals are used to identify like components in FIGS. 11 through 14. Transport truck 94 is specially designed for transporting conventional chairs of the character shown in FIG. 11, that is non-folding chairs having four spaced apart, ground engaging legs.

[0039] In this third embodiment of the invention, the transport truck comprises a base assembly 96, which is similar construction to base assembly 26 and includes transversely spaced-apart sides 98 and 100 and longitudinally spaced-apart ends 32 and 34 connected to and spanning sides 98 and 100. As best seen by referring to FIG. 11, base assembly 96 also includes a longitudinally extending central support 102 and a plurality of spaced apart article support members. However, these article support members, which are generally identified by the numeral 104, extend longitudinally of the base assembly and are generally parallel to central support 102. These uniquely configured article support members comprise a part of the first and second chair support assemblies of the apparatus of this latest of form of the present invention which span and are connected to longitudinally spaced apart ends 32 and 34. More specifically, each article support member 102 of the first and second chair support assemblies here comprises a supporting track which is constructed and arranged to receive a pair of the ground engaging legs of a conventional chair with an. In this latest form of the invention side members 98 and 100 are generally channel and the shaped and are adapted to receive a pair of the ground engaging legs of the lowest most chair of the array of stacked chairs “C”. Support members 102, as well as side members 98 and 100 are generally channel shaped so as to limit transverse movement of the stack of chairs relative to the base. Ground engaging wheels 38 are connected to base assembly 66 in the manner shown in FIG. 11.

[0040] Provided at either end of the base assembly 96 is a generally vertically extending end support assembly 106. Each end support assembly 106 is of similar construction to end support assemblies 40 and comprises a pair of generally vertically extending support members 108 which are connected proximate their lower ends to base assembly 66. To push or pull the transport truck along the ground, a push bar or handle assembly 44 is affixed to and spans support members 108 in the manner best seen in FIG. 11. As before, each handle assembly 44 includes a pair of generally cylindrically shaped hand grip portions 44a. Also forming a part of each end support assembly 106 is a transversely extending top member 108. Unlike end support assemblies 40 each end support assembly 106 includes a pair of angularly extending support braces 110. As in the earlier described embodiments of the invention, the transport truck is provided proximate each corner with a curved article retaining member 47.

[0041] Connected to and spanning support assemblies 106 is a longitudinally extending beam 112.

As best seen by referring to FIG. 16, base assembly 126 also includes a longitudinally extending central support 134 and a plurality of spaced apart article support members. These article support members, which are generally identified by the numeral 136, extend longitudinally of the base assembly and are generally parallel to central support 134. As in the previously described embodiment of the invention, each article support member 136 comprises a supporting track which is constructed and arranged to receive a pair of the ground engaging legs of the chairs to be transported on the transport track. In this latest form of the invention side members 130 and 132 are also track shaped and are adapted to receive the ground engaging legs of the folding chairs positioned along the track in the manner shown and FIG. 15. Support members 136 as well as side members 130 and 132 are uniquely shaped so as to limit longitudinal movement of the chairs. More particular, as best seen in FIGS. 15 and 16, each of the legs supporting tracks, as well as side members 98 and 100, provided with a plurality of longitudinally spaced apart protuberances 140. The valleys 140a which are disposed between each of the protuberances 140 receive the legs of the folded chairs and restrain them from moving longitudinally along the tracks. To maintain a particular group of folding chairs in the correct orientation along the tracks, a frame like assembly 141 is provided. Frame assembly 141 includes an upper frame portion 141a, which engages the group of folding chairs and a curved, track engaging portion 141b the legs of which are receivable within the valleys 140a formed between protuberances 140.(FIG. 15). As before, ground engaging wheels 38 are connected to base assembly 126 in the manner shown in FIG. 17.
