Abstract
A backpack provided with a cushioning bladder, the lower part of which extends across and beneath the bottom of the pack and an upper part extending part-way upwardly along the forward panel that generally conforms to the shape of the curvature of the thoracic region of the spine. The bladder may be filled with padding material such as a gel, foam, rubber or fluid.
Description
- The present application is a Continuation-in-Part of Non-Provisional application Ser. No. 11/101,044 filed Apr. 7, 2005. This prior application is incorporated herein by this reference and the benefit of its filing date is claimed herein as well.
- 1. Field of the Invention
- This invention relates to backpacks of the type used by, for example, students to carry books, hikers to carry gear and the like. The backpack normally contains a pack and one or more pockets for storing items. The backpack is then strapped to the back of a user and carried in that fashion. The backpack described herein is of the type that uses a cushioning bladder and positioned beneath the pack and part-way up the forward panel of the backpack and the user's back and for the purpose of relieving stress, weight and pressure on the back.
- 2. Description of the Prior Art
- It is known that the abutting relation of the forward panel of the backpack against the back and spinal column can cause pain, fatigue and perhaps degeneration to affected areas of the back and spine. It is also known that most backpacks in use today place the majority of the weight of the backpack and its contents on the shoulders and on the middle and lower part of the back of the user.
- In a number of cases, cushioning bladders have been utilized to provide support and/or avoid contact with particular areas of the back and spinal column.
- Notwithstanding, there is still a need for a backpack employing a cushioning bladder for better distribution of the weight away from the user's back.
- An object of the invention is a backpack that when worn minimizes stress, weight and pressure on the back.
- These and other objects, features and advantages are accomplished in accordance with the teachings of the present invention, one illustrative embodiment of which comprises a backpack provided with a cushioning bladder, the lower part of which extends across and beneath the bottom of the pack and an upper part extending part-way upwardly along the forward panel that generally conforms to the shape of the curvature of the thoracic region of the spine. The bladder may be filled with padding material such as a gel, foam, rubber or fluid.
- The bladder may be enclosed within a zippered bag wrapped around it that is joined to the outer surface of the backpack. Where the bladder is inflatable, a pump is provided for inflating the bladder.
- Other objects, features and advantages of the present invention will be apparent from the following detailed description and accompany drawing, wherein:
-
FIG. 1 is a perspective view of the backpack of the present invention; -
FIG. 2 is a side view of the backpack of the present invention with the backpack's bladder deflated; -
FIG. 3 is a side view of the backpack of the present invention with the backpack's bladder inflated; -
FIG. 4 is a view of the opposite side of the backpack when resting against a user's back, partially cut away; and, -
FIG. 5 is a schematic side sectional view of an alternate embodiment of the backpack, partially cut away showing the positioning of the backpack relative to the user's back and spinal column and with the bladder filled with padding material. - Referring now to
FIGS. 1 through 4 of the drawing, abackpack 10 is shown having aforward panel 11 that faces a user's back when worn,adjustable straps solid sheet 14, as of plastic or a composite, is sewn into and across and forms, with the lower part of the backpack material, thebottom 15 of the backpack. Optionally, anadjustable waist belt 16 for securement about the user's waist is provided. Thestraps - Normally, the
forward panel 11 forms one wall of a rearward-facing pack for carrying various articles. Typically, thebackpack 10 will have a number of other pockets for receipt and carrying of items as well. - In a typical embodiment the
backpack 10 is 20 inches high, 14 inches deep and 12 inches wide. However, thebackpack 10 is to be made with differing dimensions, depending upon the size of the user. The backpack is made of canvas, typically, except for thesolid sheet 14 of the bottom. - The
backpack 10 is also provided with astrap 18 at its top for hanging the backpack when not being carried by a user. - In accordance with one teaching of the present invention, the backpack is provided with a
cushioning bladder 21, in this case inflatable, thelower part 22 of which extends across thebottom 15 beneath the pack, and an upwardly extendingpart 23 positioned entirely across theforward panel 11 and from near the bottom, typically four inches from the bottom of thepanel 11, extending upwardly, typically 8 to 10 inches, so as when inflated, it generally conforms to the shape of the curvature of the thoracic region of the spine. Thebladder 21 is of flexible material such as rubber, elastomeric or polymeric material. Thebladder 21 is enclosed within a zipperedbag 24 wrapped around it that is joined to the outer surface of the backpack. - A
pump 31 is provided for inflating thebladder 21. Thepump 31 is hand operated with a bulb-shaped configuration. Thepump 31 is connected to thebladder 21 by means of atube 32. Anair valve 33 connected to thetube 32 controls the amount of air flow into thebladder 21 and maintains thebladder 21 in inflated position after air has been pumped in, and also permits deflation of thebladder 21. Thepump 31 andvalve 33 may be stored in aside pocket 34 of thebackpack 10 provided for that purpose. Optionally, the pump could be battery operated. - In use, the user straps the
backpack 10 on his shoulders so it rests comfortably on same. Thebladder 21 is then inflated, the amount of inflation being dependent on the individual's comfort level. Thebladder 21 can expand up to four inches in width. - In partially inflated position (
FIGS. 3 and 4 ), the bladder begins to expand as it is filled with air. In fully expanded condition (dotted area inFIG. 4 ), thelower part 22 of thebladder 21 will rest upon the user's buttocks. In fully inflated position, theupper part 23 of thebladder 21 conforms to the curvature of the thoracic region of the user's body and rests comfortably against the back. Thesolid sheet 14 at the bottom of the backpack prevents the expansion of thebladder 21 from taking up space in the pack. In this way it is assured that thelower part 22 of the bladder will expand under the pack and not into it. The feeling to the user is that a significant portion of the weight of the backpack and contents is removed. After or along with inflation, the shoulder straps may be adjusted so that the backpack finds itself in the desired position. - Instead of an air bladder, in accordance with another teaching of the present invention and with reference to
FIG. 5 ,padding 41 can be used to fill thebladder 41, but with less desirable results. With an air bladder, there can be adjustment of the inflation level of the bladder to different levels for different uses. - In the
FIG. 5 embodiment, the bladder is molded to retain its shape.Padding 41 can be a soft supportive material. Examples of same are: gel such as silicone gel; foam such as polystyrene; liquid/fluid such as ethylene glycol; and, rubber such as ethylene vinyl acetate. These examples are in way intended to be limiting. - In any of the embodiments, the bladder may be so constructed and arranged to a generally L-shaped configuration, with the bladder lower part for resting upon and generally conforming to the buttocks area of the user, and the bladder upper part continuing from the bladder lower part, extending at an angle part-way up the forward panel, so as to rest upon the user's back and generally conform to the curvature of the thoracic region of the user's body.
- The back is relieved from stress, weight and pressure. The inflation of the air bladder moves the pack away from the back, shifting some of the weight to now be borne by the shoulders and with part of the weight now being supported by the buttocks area.
- The backpack can be made in different styles and sizes, for example, a student pack, one for hiking and one for military use.
- It should be obvious that changes, additions and omissions may be made in the details and arrangement of parts without departing from the spirit and scope of the invention as hereinafter claimed.
