20100187275 | AIR-CUSHION BACKPACK - A backpack has a pocket and at least one shoulder strap for supporting the backpack on a shoulder of a user. A generally rigid plate and a flexible inflatable bladder are in the pocket with a load bearing bag connected to the pocket for holding a load. A tubular extension extends from the bladder and into the shoulder strap for inflating and deflating the bladder and a mouth-inflatable check valve is connected to the tubular extension at a location spaced from the bladder and positioned so as to be accessible to the user for inflating the bladder by blowing into the check valve. A curved semirigid liner inside the material of the shoulder strap near the bladder forms a semirigid channel for receiving the tubular extension. | 07-29-2010 |
20110120893 | AIR-CUSHION BACKPACK AND LAPTOP SLEEVE - A backpack has a front pocket containing a plate and a pair of shoulder straps for holding the plate against the back of a user. A pressurizable, flexible and elastic bladder covers the plate and has inside surfaces with an embossed pattern for preventing sticking together of facing walls of the bladder to facilitating an initial inflation of the bladder. A pair of tubular extensions extend from the bladder and into the shoulder straps, one of the tubular extensions being for inflating and deflating the bladder. A mouth-inflatable check valve connected to extension is location so as to be accessible to the user for inflating the bladder and a valve cover is detachably connected over the entire mouth engageable perimeter of the check valve for keeping it clear. Semi-rigid liners in the shoulder straps near the bladder form channels for facilitating inflating and deflating of the bladder. A pair of cushion panels in, or separate from the backpack, include pluralities of offset parallel, partially filled air tubes spaced by webs for minimizing volume when there is nothing between the cushion panels. | 05-26-2011 |
20120006600 | Luggage Weight Threshold Indicator - An integral weighing device for determining whether the weight of a luggage container and its contents exceed a maximum allowable amount simply by suspending the container by its handle. If the container weighs more than a set amount the integral weighing device provides a visual cue that the container exceeds the predefined weight. The integral weighing device comprises a torsion spring mounted within a housing, and a cord attached to each end of the torsion spring and fed via a guide-way through and out of the housing to an externally accessible grip handle. An indicator arm is rotationally mounted to the housing. When a person lifts the luggage by the grip handle the force is transferred to the torsion spring causing angular deflection toward the indicator arm. If the container exceeds the set weight the indicator arm provides a visual cue that the bag exceeds the predetermined weight. | 01-12-2012 |
20140198442 | RETRACTOR CORD ASSEMBLIES FOR CARRIED ARTICLES - A low-profile retractable cord system in which a line is attached to a pair of retractor mechanisms located in the sides of an article to be carried (such as a briefcase, a purse, a handbag, suitcase, tote, bag, knapsack, sports bag, gym bag, etc.). The line is high-tensile braided line threaded out through eyelets which are offset inwardly and downwardly from the upper corners of the article to be carried. This way, the line and shoulder pad attached thereto lie flat along the carried article. Various retractor mechanisms are shown, including an opposed pair of coil-spring-biased reels, opposed independent pulley mechanisms, or a common pulley mechanism. An alternate embodiment employs a single retractor mechanism and line for a single loop-handle is also shown. | 07-17-2014 |
