Description

BACKGROUND OF THE INVENTION

Technical Field

This invention relates to fixtures for retail stores, and more specifically to a fixture for holding a paper-type bag open at a bagging station while the bag is being filled.

State of the Art

A bagging station is a fixture in a retail store where purchased items are loaded into bags so the items can be carried out of the store by the customer. Bagging stations are often located at checkout registers where purchased items are paid for. Bagging stations are usually designed to store and dispense plastic bags. Bagging stations that dispense plastic bags will have hooks for hanging the plastic bags from. When paper-type bags are being dispensed at a bagging station instead of plastic bags, it is often difficult to keep the open bag in one place while it is being filled. The hooks used for plastic bags are usually not useful for paper-type bags. The open bag is often placed on the bagging station top surface, but it often slides and moves around unless something is used to hold the bag in place.

Accordingly, what is needed is a bag retaining fixture that can temporarily hold an open paper-type bag in place at a bagging station, keeping the open bag from moving around while it is being filled at the bagging station.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The disclosed invention relates to fixtures for a retail store, and more specifically to a fixture for holding a paper-type bag in place while the bag is being filled at a bagging station.

A bagging station is a location in a retail store where purchased items are loaded into bags so the items can be carried out of the store by the customer. Bagging stations are often at checkout registers where purchased items are paid for. Bagging stations are usually designed to store and dispense plastic bags. The bagging station for plastic bags will often will have hooks and arms for holding stacks of plastic bags, and for hanging plastic bag arms from, to keep the plastic bag open while filling. In some locations and jurisdictions, however, paper-type bags are used instead of plastic bags. A paper-type bag is a bag made of semi-rigid material. Paper-type bags includes traditional brown paper bags, as well as bags made of semi-rigid plastic or composite materials. Paper-type bags often do not hang from their arms, but instead are rigid enough to sit, when open, on their bottom on a flat surface. The term “paper bag” is used throughout this document, but it is to be understood that bags formed of other semi-rigid material such as plastic or composite materials can be substituted for the paper bags described in this document. Some customers and locations prefer paper bags over plastic. Some jurisdictions have ruled that paper bags should be used instead of plastic bags. Environmental laws or restrictions can often dictate that paper bags be used in retail stores instead of plastic bags.

In order to make bagging stations work well with paper bags, it is desirable to have a bag retaining fixture that will hold an open paper bag on the bagging station while the bag is being filled. Described herein is a bagging station that uses a bag retaining fixture. The bag retaining fixture holds open paper bags at the bagging station so the paper bags can be filled without the bag moving or falling off the bagging station. The bag retaining fixture includes an elongate rod and a roller wheel that slides onto the elongate rod and rotates on the elongate rod. The bag retaining fixture is coupled to the bagging station. The elongate rod, with the roller wheel slid onto the elongate rod, is coupled to a side of the bagging station such that the elongate rod with roller wheel captures a side of a paper bag between the roller wheel and the side wall of the bagging station. The bagging station can have a number of bag retaining fixtures coupled to it, so that a number of bags can be held open at a time and filled with purchased items. The described bag retaining fixture can be used with any bag with a side that can be held between the bag retaining fixture and a wall of the bagging station. The bag retaining fixtures keep paper bags in place at the bagging station, allow bagging station carousels to rotate without throwing off the open paper bags, and keeps bagging stations neat and useful with paper bags as well as plastic bags.

FIG. 1 through FIG. 4 shows a bagging station 108 for use in a retail store for filling paper-type bags. FIG. 1 shows bagging station 108 with a plurality of bag retaining fixtures 110 for holding paper bags 174. FIG. 2 shows an enlarged view of bag retaining fixture 110 holding an open paper bag 174 at bagging station 108 of FIG. 1. FIG. 3 shows a side wall 170 of bagging station 108 with two bag retaining fixtures 110 coupled to side wall 170. FIG. 4 shows a side view of bag retaining fixture 110 coupled to side wall 170 of bagging station 108 of FIG. 1. Bag retaining fixture 110 holds bags 174 open at bagging station 108 so that each bag 174 can be filled with purchased items and does not fall off of bagging station 108.

Bagging station 108 is a carousel-type bagging station that is often used at a checkout register of a retail store for bagging items that have been purchased in the retail store. Bagging station 108 includes a bagging station carousel 102 that includes a rotating platform 101 and a center section 103 with three side walls, including side wall 170 and side wall 171. Bagging station 108 also includes at least one bag 174 setting on carousel 102. Center section 103 has a cabinet 172 for holding a stack of paper bags 176, in this embodiment. Bagging station 108 includes at least one bag retaining fixture 110 coupled to one of the side walls 170 or 171. Center section 103, in this embodiment, has a number of bag retaining fixtures 110 on its side walls 170 and 171, as shown in FIG. 1. Bag retaining fixtures 110 hold paper bags 174 from moving around or falling off of bagging station 108, as shown. Each bag retaining fixture 110 holds a side 192 of a bag 174 between a roller wheel 114 and side wall 170 or 171 of center section 103, as best seen in FIG. 2. Rotating platform 101 rotates to allow a bagger to place items in paper bags 174 as they are purchased. Paper bags 174 that are full can be removed from bagging station 108 and carried out of the retail store. Once a bag 174 is removed, an empty paper bag 174 can be retrieved from stack of paper bags 176, opened, and put in place on carousel 102 for filling, held in place with bag retaining fixture 110. FIG. 1 through FIG. 4 show bag retaining fixture 110 being used to hold the side of paper bags 174 on bagging station 108, but it is to be understood that bag retaining fixture 110 can be used with any type of bag on any type of bagging station. Bagging fixture 110 can be used to hold the side of any type of bag against a surface.

FIG. 5 through FIG. 7 shows details of bag retaining fixture 110. FIG. 5 shows a perspective view of bag retaining fixture 110. Bag retaining fixture 110 includes an elongate rod 112 and a roller wheel 114. FIG. 6 shows a perspective view of elongate rod 112 of bag retaining fixture 110. FIG. 7 shows a perspective view of roller wheel 114 of bag retaining fixture 110.

Each bag retaining fixture 110 is coupled to a side wall 170 or 171 of bagging station 108, as shown in FIG. 1 through FIG. 4. Each bag retaining fixture 110 holds a bag 174 on bagging station 108 by pressing roller wheel 114 against side wall 170 or 171 and pressing a side 192 of bag 174 between roller wheel 114 and side wall 170 or 171, as best seen in FIG. 2. The pressure of roller wheel 114 on side 192 of paper bag 174 keeps bag 174 in place on bagging station 108 as purchased items are placed in bag 174. Roller wheel 114 is coupled to and rotates on elongate rod 112. The rotation of roller wheel 114 on elongate rod 112 makes it easy to slip side 192 of paper bag 174 in between roller wheel 114 and side wall 170 or 171 to fill paper bag 174, and then to remove side 192 of paper bag 174 from between roller wheel 114 and side wall 170 or 171, once paper bag 174 is full. Elongate rod 112 biases roller wheel 114 against side wall 170 or 171 of bagging station 108 to hold side 192 of bag 174 between roller wheel 114 and side wall 170 or 171.

Bag retaining fixture 110 includes elongate rod 112 and roller wheel 114, as shown in the figures. Roller wheel 114 is coupled to elongate rod 112. Roller wheel 114 is a slidable roller wheel 114 because roller wheel 114 slides onto elongate rod 112 to couple roller wheel 114 to elongate rod 112. Also, roller wheel 114 slidingly rotates on elongate rod 112 once roller wheel 114 is slid onto elongate rod 112. Roller wheel 114 sliding onto elongate rod 112 means that elongate rod 112 extends through an axle hole 117 in roller wheel 114 (see FIG. 4, FIG. 5, and FIG. 7). With roller wheel 114 coupled to elongate rod 112, elongate rod 112 acts as an axle for roller wheel 114, and roller wheel 114 rotates on elongate rod 112.

Roller wheel 114 has a roller wheel diameter 115 (FIG. 4) that is large compared to an elongate rod diameter 121 (FIG. 5) of elongate rod 112. In the embodiment shown in the figures, roller wheel diameter 115 is 10 times larger than elongate rod diameter 121. In some embodiments, roller wheel diameter 115 is 5 times larger than elongate rod diameter 121. In some embodiments, roller wheel diameter 115 is 20 times the size of elongate rod diameter 121. In some embodiments, roller wheel diameter 115 is 5-20 times larger than elongate rod diameter 121. Having roller wheel diameter being 5-20 times larger than elongate rod diameter 121 makes it easier to rotate roller wheel 114 on elongate rod 112 than if roller wheel diameter 115 was less than 5 times the size of elongate rod diameter 121. When roller wheel diameter 115 is less than 5 times the size of elongate rod diameter 121, roller wheel 114 does not rotate as easily, making it more difficult to insert and remove side 192 of paper bag 174 from between roller wheel 114 and side wall 170 or 171 of bagging station 108. When roller wheel diameter 115 is more than 20 times larger than elongate rod diameter 121, roller wheel 114 can become too large and bulky and impede the loading of items into bag 174.

Elongate rod 112 has an elongate rod first end 116 and an elongate rod second end 118. Elongate rod first end 116 and elongate rod second end 118 are both coupled to a side wall 170 or 171 of bagging station 108, as shown in FIG. 1 through FIG. 4.

Elongate rod 112 is divided into several sections, with bends between the sections that help shape elongate rod 112 to hold bags 174 on bagging station 108. Elongate rod 112 has a first end portion 120 and a second end portion 124, see FIG. 5 and FIG. 6. Each of first end portion 120 and second end portion 124 are circular shaped. First end portion 120 and second end portion 124 are each lengths of elongate rod 112 at either end of elongate rod 112. First end portion 120 and second end portion 124 are each bent or otherwise formed into a circular shape, as shown in the figures, so that a first coupler 197 can be extended through first end portion 120 to couple first end portion 120 and elongate rod 112 to side wall 170 (or side wall 171), and a second coupler 199 can be extended through second end portion 124 to couple second end portion 124 to side wall 170 (or side wall 171) as shown in FIG. 1 through FIG. 4. First and second couplers 197 and 199 are screws and washers in this embodiment, but this is not meant to be limiting. First and second couplers 197 and 199 can be any coupler (screw, bolt, nail, etc) that couples first and second end portions 120 and 124 to side wall 170 or 171.

First end portion 120 extends from elongate rod first end 116 to a first leg portion end 182, as shown in FIG. 5 and FIG. 6.

A washer of coupler 199 has a diameter larger than the diameter of the circular shape of second end portion 124. Coupling coupler 199 to side wall 170 presses second end portion 124 against side wall 170 and couples second end portion 124 and bag retaining fixture 110 to side wall 170. Once first and second end portions 120 and 124 are coupled to side wall 170 with couplers 197 and 199, first leg portion 120 and second leg portion 124 are each parallel to side wall 170 (or 171). For example, side wall 170 lies in a plane 175, as shown in FIG. 4. First and second end portions 120 and 124 lie in a plane 180, as shown in FIG. 4. Plane 175 is parallel to plane 180 in this embodiment, meaning first and second end portions 120 and 124 are parallel to side wall 170.

Elongate rod 112 also has a first leg portion 136, a second leg portion 138, and a bag retaining section 130, see FIG. 5 and FIG. 6. First leg portion 136, second leg portion 138, and bag retaining section 130 are each lengths of elongate rod 112 that are bent or otherwise formed into a shape to hold a paper bag on bagging station 108. Bag retaining section 130 holds roller wheel 114 and biases slidable roller wheel 114 against side wall 170 or 171 to hold side 192 of bag 174 between roller wheel 114 and side wall 170 or 171.
