The disclosed embodiments relate generally to the field of systems and methods for dispensing waste bags.
In the commercial cleaning industry, many workers are required to remove an existing trash bag including waste, and replace the bag with a new trash liner. Conventionally, these workers often carry the replacement bags around in the packaging in which they were purchased. Trash bag packs typically come in the form of perforated or nonperforated rolls, and include the bag rolls in apron pockets or rest the bags on or in cleaning carts so that they can carry the bags with them as they work. A typical approach to dispensing is executed by unrolling a single bag, and then where the roll is perforated, tearing that bag from the next bag in the roll.
Some bag-dispensing arrangements are known in the art. For example, U.S. Pat. Nos. 5,425,513, 6,427,839, 2005/0263087, 2009/0266853, 2011/0132952, and 2011/0272442 all related to some form of bag dispensing.

Embodiments provide systems and a method for dispensing bags.
Hood 102
Hood 102 includes a downwardly curved front portion 110 and a drops down into a recessed ledge area 113 defined from below by a drive bar 112, and on the sides by a pair of opposing laterally symmetrical side walls 111. Drive bar 112 is supported in a bar-receiving rectangular recess 113 (see
A pair of vertical compression springs 118 are each mounted on a bottom end by the upper surface located near the mouth of the base 104, and at an upper end underneath the outermost undersurfaces of the drive bar 112. These springs bias the mouth open, but as will be discussed hereinafter, the mouth is normally latched shut during normal use. The springs 118 are located laterally outside the drive bar 112 and the bar 118 so as to not interfere with operations.
A plurality of rod-receiving spaced-apart hinge sections 120 (
Base 104
Base 104 further includes a slightly backwardly angled, vertically corrugated back wall 130 (
Internally, a bag-path deviating riser 141 extends laterally to the extent of and is immediately behind the lower member 140. A cross section of riser 141 can be seen in
A balance between dispensability and resistance offered is struck by opposing interlocking ridges 171 and 141 (see
The base is made more sound by a pair of screw-in cylindrical plastic/rubber thumb screw base levelers 143 (see
Mount 106
Back supporting mount 106 includes an upper shelf top 144, side walls 146, and a bottom shelf 148 at the margins of a back wall 150 (see
The upper shelf configuration 144 of the mount 106 is configured for receipt underneath a receiving canopy 156 of the base 104 (
In order to fix the base 132 onto the mount 106, screws 158 (each having a washer 160) can be first received through upper apertures 162 made through the upper portion of wall 130, and slide on openings 164 located on the lower portion of wall 130. The screws 158 are received into receiving bores 157 defined into the internal mount structures. Thus, assuming the mount 106 has be initially secured to some supporting surface (e.g., a waste vessel or building structure), the base 104 and hood 102 assembly can easily be attached and removed if needed.
Latching
To secure the fully assembled system 100 in the first mode (as shown in
Loading
The opening up of the hood 102 enables a roll of bags to be loaded into the system 100. Preferably the unrolling required during dispensing will occur from the top of the roll, and a first bag of the roll brought between the upper and lower brakes 170 and 140, and then the hood closed to clamp the first bag in place between the brakes. Ordinarily the user pulls the bags in the roll out one at a time, and tears each off for use.
Resistance System
The tension between the brakes 170 and 140 is delivered by compression created, and also made to be adjustable (using systems shown primarily in
In embodiments, The upper resilient member can be configured to be reversible to create engagement differences between the upper and lower resilient members 140 and 170. To enable this (see
Biased bar member 182 is biased by tandem compression springs 186. Each of compression springs 186 are cylindrically mounted outside on one of the twin bolt posts 116 such that the tops of each spring 186 bear upward against the bottom surface of the drive bar 112, which moves up or down on the posts 116 inside the bar-receiving rectangular vertical recess 113 (see
Cam Assembly/Setting Resistance
The resistance offered by the opposing lower and upper brakes 140 and 170 is set by the control knob arrangement 108, which is bolted onto the downwardly curved front portion 110 of the hood 102 using two bolts 194. The heads of the bolts 194 are shown in
Rotation created in a knob 212 is imparted to the other mechanics by rotating axle 208. Axle 208 has an irregularly shaped cross section which is consistent along it's length. More specifically, the axle 208 is an elongated member having flat sides and arcuate top and bottom (all when viewed in cross section at any point along the length of the axle 208). The axle 208 also includes a crosswise aperture 210 which will be used to receive a compression pin 220 for assembly. The knob 212 is engaged by a user in selecting a resistance setting using indicator markings 224 made to exist on the dial 199.
In terms of assembly (see
The locating pin 214 is then pressed into (and fixed inside) an aperture 226 on the forward side of the cam 198 as can be seen in
After installation on the axle 208, the rotatable cam 198 is configured to bear down on the top of the middle of drive bar 112 to a variety of levels. The extent that the drive bar 112 is moved downward is dependent on the radial position of the cam 198 (e.g., in a cam-follower relationship, in embodiments). Thus, the drive bar 112 acts as a follower relative to the to the cam 198. This cam/follower system causes the drive bar 112 to respond to the profiled shape of the cam periphery (thus, translating the rotation of the cam 198 into the linear downward motion of the drive bar 112.).
The cam 198 profile is configured to be diverse when viewed in cross section (see
Other peripheral features of the cam 198 include a gradually ramped up edge 202 portion, which increases the cam radius at the point of engagement assuming rotation in a clockwise direction (see
Overall Functionality/Dial Settings
The system 100 including a selection knob 212 rotatable to accomplish a neutral setting, as well as a variety of increasing or decreasing resistance settings in the brakes 170 and 140 enables a worker to install bags with greater efficiency, and also affords the system to accommodate a variety of rolled bag types. For example, some commercially available rolled trash bags are physically integrated one with the next, but perforated and thus can be torn apart along perforation lines. Other kinds of rolled bags are not integral with one another, but rolled together such that one bag end slightly overlaps the next bag. The overlap is made to an extend that one bag can be dispensed at a time. The disclosed system 100 is able to dispense any of these sorts of bags through the selection of an appropriate dial selection (made using knob 212). In embodiments, the dial can be labeled with bag types to aid the worker is selecting a resistance setting.
Nonperforated bags, during dispensing, merely need unrolling, and thus, require nominal or zero resistance force. Thus, moving the knob to an indication 238 results in a neutral setting where the resistance in the brakes 140 and 170 is minimized the extent that they separate will be the most appropriate for dispensing nonperforated bags. In terms of what is happening behind the dial, a setting of pin 214 into hole 246 will result in this desired neutral setting where the brakes 140 and 170 are open slightly.
Perforated bags, however, require a tear off force. Although there are numerous kinds of perforated bag rolls on the market that function in the same general manner, each of these individual bag types can require different optimal tear-off force levels. To handle this, a multiplicity of resistance levels are offered to a user, made selectable using a pointer 201 on knob 212 at any one of a plurality of radiating indicators existing on (on dial 199). The selection made will depend on the particular type of bag being used. Looking at the details in
