Description

BACKGROUND OF THE INVENTION

This invention relates generally to carrying cases and, more particularly, to a backpack having an integrated seat cushion.

Many people find themselves in situations where they must sit for long periods of time on uncomfortable seating. Common situations in this regard include students studying for long periods of time in a library or spectators at sporting events. In both situations, the person typically desires to carry several items with them, such as books, food, or the like, and also desires to be comfortable while sitting.

Various proposals for carrying portable seating, chairs, or cushions, have been made in the prior art. While assumably effective for their intended purpose of providing portable seating, the existing devices lack all of the utilitarian aspects of a backpack. More particularly, the existing devices are merely collapsible seats that would need to be transported in addition to a backpack or other case for books and supplies. Further, the existing cushion devices do not meet the specific needs of a student, including the ability to carry multiple books and to provide a comfortable cushion device while studying in a library.

Therefore, it would be desirable to have a backpack that includes a portable seat cushion for providing comfortable seating and carrying books or supplies. Further, it would be desirable to have fully functional seating comfort while maintaining a fully functional backpack.

SUMMARY OF THE INVENTION

A combination backpack and cushion device according to the present invention includes distinct first and second backpack sections that are attached together. In addition, a cushion member is connected to the first and second backpack sections and is movable between a first configuration sandwiched between the first and second backpack sections and a second configuration in which the first and second backpack sections are further separated by the cushion in an elongate configuration.

In the second configuration, the cushion device includes an elongate cushion element having one or more cushions. Preferably, the cushion device includes an initial cushion and an end cushion, the cushion element providing a cushion for placement on a chair seat and another cushion for placement against a chair backrest.

The initial cushion is flexibly attached to the first backpack section and the end cushion is attached to the second backpack section. In use, therefore, the first backpack section may hang below a chair sear when the initial cushion is situated on the seat and the second backpack section can be draped over a chair back when the end cushion is used as a back rest. While in use, the first and second backpack section may be releasably strapped together behind or below the seat to keep the entire device in place.

Therefore, a general object of this invention is to provide a combination backpack and cushion device that enables a student to carry books and to have a comfortable cushion for sitting on an otherwise uncomfortable chair surface. Another object of this invention is to provide a combination backpack and cushion device, as aforesaid, that includes compartments for carrying books and supplies.

Still another object of this invention is to provide a combination backpack and cushion device, as aforesaid, in which the cushion device includes one or more cushions.

Yet another object of this invention is to provide a combination backpack and cushion device, as aforesaid, which is movable between one configuration in which the cushion device is sandwiched between backpack sections and another configuration in which the backpack sections and cushion members are in an elongate and spread out arrangement.

Other object and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, an embodiment of this invention.

The first backpack section 110 defines a first storage area 118, and the second backpack section 120 defines a second storage area 128. Means 140 for releasably attaching the first and second backpack sections 110, 120 are preferably included, such as clips, hook and loop fasteners, snaps, a zipper, and other fastening mechanisms. Means 125 for holding the second backpack section 120 is preferably also included, such as a carrying strap or a handle.

The elongate cushion element 130 includes one or more cushions 132 arranged in an elongate row, and the cushion element 130 is flexibly connected to the first and second backpack sections 110, 120 for movement between a first configuration 130a and a second configuration 130b. The cushion element 130 is sandwiched between the first and second backpack sections 110, 120 at the first configuration 130a, and the cushion element 130 further separates the first and second backpack sections 110, 120 at the second configuration 130b. More particularly, the backpack sections 110, 120 and cushion element 130 may be spread out into a more elongate and linear type of arrangement in the second configuration so as to laid flat or draped over a chair (FIGS. 2. 3a. and 3b).

The cushion element 130 includes an initial cushion 134 and an end cushion 136, each having opposed first and second ends 134a, 134b, 136a, 136b and opposed sides 134c, 134d, 136c, 136d. The initial cushion 134 is flexibly connected to the first backpack section 110, and the end cushion 136 is flexibly connected to the second backpack section 120. If there is only one cushion 132, that cushion 132 is both the initial cushion 134 and the end cushion 136.

In a first embodiment, shown in FIG. 1 through FIG. 4, the device 100 is for use with a chair 10 having a seat 12 and a back 14 (FIGS. 3a and 3b).
