Description

BACKGROUND OF THE INVENTION

This invention relates generally to seat devices which are transportable and adjustable, as for use by musicians and others; and more particularly concerning a seat device which defines an interior storage area, for example to carry musical equipments or music sheets.

There is a need for devices of the above type, since musicians constantly move between performance locations, and have a need to carry their equipments and music, including seats which they have become accustomed to.

SUMMARY OF THE INVENTION

It is a major object of the invention to provide an improved device of the above type, which has many highly advantageous features. Basically, the preferred device includes:

a) upper, lower and intermediate sleeves having telescopic interconnections,

b) a seat on the upper sleeve,

c) transporting structure including wheels carried by the lower sleeve.

d) and adjustable locking elements associated with at least two of the sleeves for locking the two sleeves in selected positions for vertical height adjustment.

The referenced elements are preferably located proximate side walls of at least two sleeves, and are adjustable at the interior of the structure.

It is another object to provide one of the locking elements to define at least one vertical series of slots carried by a side wall of one of the intermediate and lower sleeves. Another of such elements constitutes at least one support carried by the side wall of the other of said intermediate and lower sleeves and located to be selectively received in each of the different slots. The slots may be defined by at least one plate attached to the side wall of one of the intermediate and lower sleeves, with the plate facing to the interior of said sleeve assembly. The support may comprise a threaded member projecting sidewardly through the walls of the intermediate and lower sleeves, and through the plate.

Yet another object is to provide three of such vertical series of slots, and there are at least three of the supports respectively associated with said at least three series of slots. Such slots may advantageously define dwell regions for reception of at least one support, to block twisting displacement of the supports out of the slots without relative vertical movement of the intermediate and lower sleeves.

A further object is to provide at least one trunnion on the lower sleeve, the transporting structure including at least one wheel carrying axle carried by that trunnion. As will be seen, there are typically two trunnions carrying the axle, and a handle projects downwardly between the trunnions for connection to the axle, and also projecting upwardly at a side of assembly. At least one strap is typically carried by the assembly to wrap the adjacent handle and the assembly, for retaining the handle to the assembly.

A further object is to provide multiple sleeve retention straps spaced about the assembly and acting to hold the sleeves against relative vertical separation in a selected position of vertical height adjustment. The internal supports are then enabled to be held in selected dwell regions by the external retention straps acting on the sleeve assembly.

An additional object is to provide a transporting structure that includes an upright handle having operative connection to the lower sleeve, at a lower elevation, and also releasably connected to at least one of the sleeves at an upper elevation.

These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

DETAILED DESCRIPTION

In the drawings, the transportable, adjustable seat assembly 10 includes upper, lower and intermediate cylindrical, thin-walled sleeves 11 , 12 and 13 respectively, and which have telescopic sliding interconnections. A seat such as cushion 14 is attached at 15 to a top cover 11 a associated or integral with top sleeve 11 . A turned-down peripheral flange 11 b on the upper sleeve receives and seats on the upper, turned-down edge portion 13 a of sleeve 13 . Upper sleeve 11 and the seat 14 are removable off the intermediate sleeve, to enable access to the interior 16 of the assembly. Musical equipment and music folios may be stored in that interior, for safe transportation from one performance location to another performance location. A musician sits on seat 14 , during a performance, as seen at 17 in FIG. 2 . At that time, the bottom wall 12 a of lower sleeve 12 typically rests on a floor surface 18 , providing a wide, very stable support, as the musician shifts about on seat 14 .

Adjustable locking elements are provided in association with at least two of the sleeves, as for example sleeves 12 and 13 , for locking them in selected positions of assembly height adjustment, to suit the position and seating of the musician 17 . Such elements are preferably proximate or adjacent to thin side walls defined by the sleeves 11 and 13 . One of such elements defines at least one vertical series of slots carried by a side wall of the intermediate or lower sleeve. In the example, as seen in FIG. 6 , slots 20 are defined or formed by a plate 21 attached at 22 to the side wall portion 13 a of the intermediate sleeve 13 , as seen in FIGS. 4-6 , the slots extending sidewardly from a vertically elongated slot 23 in the plate. Plate 21 faces and is exposed to the interior of the assembly. A spacer 49 is located between the plate 21 wing nut 27 .

Another of the adjustable locking elements constitutes at least one support member, as for example, fastener 24 , carried by the side wall portion, at 12 a , of the other (sleeve 12 ) of the two sleeves 12 and 13 , and located to be selectively received in different ones of the slots 20 , for height adjustment. In the example, fastener 24 is threaded, and projects sidewardly through the sleeve walls and through the plate. A rounded head member 24 a engages the outer side wall of sleeve 12 and presents a smooth outer surface. The threaded inner end member receives a wing nut 27 , that can be loosened to enable sleeve height adjustment, or tightened to hold the sleeve in adjusted position, with the fastener 24 in a downwardly captivated position in a slot 20 . The slot has a lowermost portion 20 a that provides a downwardly gravitational position for the fastener 24 , to resist its inadvertent sideward movement such as twisting displacement.

Preferably, multiple locking elements, which are alike, are provided, as at 120° interval locations 35 spaced about assembly axis 36 , as seen in FIG. 5 , thereby providing multiple locking or sleeve orienting positions, both vertically and horizontally, about axis 36 , for maximum balance and height adjusted assembly integrity. When a height adjustment change is desired, the wing nuts are loosened, and the sleeve 13 is lowered slightly relative to sleeve 12 to free the members 24 upwardly from dwell locations at 20 a ; and the sleeve 13 is then twisted to locate the members 24 in the vertical slots 23 from which slots 20 sidewardly extend. This enables vertical displacement of sleeve 13 relative to sleeve 12 , and reverse twisting location of the members 24 in other selected slots 20 and dwells 20 a , thereby achieving stable height adjustment. The wing nuts are then again tightened. The use of three members 24 is to achieve positive, non-rocking, stake support.

At least one trunnion, and preferably two trunnions 40 are carried by lower sleeve 12 , to support a transverse axle 41 extending beyond the trunnions at 41 a and 41 b , for in turn supporting wheels 42 . The latter are located above the bottom level of the sleeve 12 transverse to bottom 12 a , to enable flat, stable positioning of the assembly on floor surface 18 . A handle 44 has a lower portion 44 a projecting downwardly between the trunnions for pivotal connection at 45 to the axle, mid-way between the wheels. The handle projects upwardly at a side of the assembly as seen in FIGS. 1 , 3 and 4 . At least one strap is carried by said assembly to wrap adjacent to the handle and the assembly for retaining the handle to the assembly. See for example, strap 47 or strap sections 47 a , buckled together at 48 , to hold the handle in an upright position, enabling tilting and wheeling of the assembly, as shown in FIG. 1 .

Also provided are multiple retainer upper and lower straps, as at 50 and 51 , spaced about the assembly at three or four locations, and acting to hold the three sleeves in inter-connected telescopic condition. Upper straps 50 are shown as connected at 50 a to the turned down rim portion 11 b of the upper sleeve 11 top; and lower straps 51 are shown as attached at 51 a to the lower sleeve 12 . Buckles 54 hold the straps 50 and 51 together, and may be loosened to enable seat removal, and access to the interior of the assembly to store or retrieve musical equipment.

The handle can then released and lowered to the floor, as during a musical performances.
