BACKGROUND
1. Technical Field
The present disclosure relates generally to shopping carts and the storage of shopping carts and more specifically to a mechanism for keeping shopping carts within a storage area.
2. Introduction
Shopping carts are provided in a retail store and are often located in the vicinity of an entrance of the retail store for easy accessibility by customers. Shopping carts are used by the customers as means to collect shopping items before checkout or purchase at a point of sale in the retail store. Shopping carts are also used by the customers to carry the purchased items from the point of sale in the retail store to a vehicle for unloading the purchased items into the vehicle. After unloading the purchased items, the shopping carts are usually returned to a storage area provided in a parking lot near the retail store. The storage area is used as a collection point for the shopping carts. An employee of the retail store can then bring back the shopping carts inside or near the retail store entrance to be used again by customers. Current configurations of a storage area for shopping carts do not prevent the shopping carts from drifting away from the storage area. As a result, the shopping carts may potentially hit or damage a vehicle in the parking lot. For example, this situation may occur when there is wind that can push a shopping cart away from the storage area.
Therefore, there is a need for a novel system or mechanism for keeping shopping carts within the storage area and preventing the shopping carts from drifting away from the storage area. The system and mechanism disclosed herein cure the above and other problems of existing storage for shopping carts.
SUMMARY
An aspect of the present disclosure is to provide a mechanism for keeping shopping carts within a storage area. The mechanism includes a mechanical stop disposed at or near the ground at an opening of a storage area that is configured to store a plurality of shopping carts, the mechanical stop being moveable from an upward locked position to a downward unlocked position, the mechanical stop being configured to engage one or more wheels of a shopping cart to keep the shopping cart inside the storage area. The mechanism further includes a release mechanism operatively linked to the mechanical stop, the release mechanism being configured to move the mechanical stop from the upward locked position to the downward unlocked position.
Another aspect of the present disclosure is to provide a storage system for shopping carts. The storage system includes a storage housing having an opening, the storage housing being configured to store a plurality of shopping carts. The storage system further includes a mechanical stop disposed at or near the ground at an opening of the storage housing, the mechanical stop being moveable from an upward locked position to a downward unlocked position, the mechanical stop being configured to engage one or more wheels of a shopping cart to keep the shopping cart inside the storage housing.

DETAILED DESCRIPTION
FIGS. 1a and 1b show a mechanism 10 for keeping shopping carts 12 within a storage area 14, according to an embodiment of the present disclosure. The mechanism 10 includes a mechanical stop 10A disposed at or near the ground 16 at an opening 14A of the storage area 14. The storage area 14 is configured to store a plurality of shopping carts 12. In an embodiment, the storage area 14 is a rectangular or square shaped area enclosed on three sides and a fourth side having the opening 14A to allow ingress and egress of a shopping cart 12 into and from the storage area 14. Of course, other shapes and sizes of the storage area 14 are also contemplated by the disclosure. In an embodiment, the opening 14A has a dimension to allow more than one shopping cart 12 to be inserted into the storage area 14 at once. In an embodiment, the storage area 14 has a rooftop 14B to cover or provide shade to the shopping carts stored in the storage area 14. In another embodiment the storage area 14 does not have a rooftop, as shown in FIGS. 2a and 2b. The storage area 14 can be made from any suitable material including, but not limited to, metal, wood or plastic, or any combination of two or more of these materials.
FIGS. 2a and 2b show positions of the mechanism 10 when actuated, according to an embodiment of the present disclosure. The mechanical stop 10A is moveable from an upward locked position, as shown in FIG. 2a, to a downward unlocked position, as shown in FIG. 2b. In an embodiment, when in the upward locked position as shown in FIGS. 1a, 1b and 2a, the mechanical stop 10A is configured to engage one or more wheels 12A of the shopping cart 12 when a user pushes the shopping cart towards the entrance 14A to store the shopping cart within the storage area 14. When in the upward locked position, as shown in FIGS. 1a, 1b and 2a, the mechanical stop 10A is also configured to engage part of the shopping cart 12, such as one or more wheels 12A of the shopping cart 12 to keep the shopping cart 12 inside the storage area 14, as shown in FIG. 1b.
In an embodiment, the mechanical stop 10A has a shape adapted to allow the shopping cart 12 to enter the storage area 14 and prevent backward movement of the shopping cart 12 out of the storage area 14. In an embodiment, the mechanical stop 10A has a wedge-like profile in a form of a ramp, as depicted in FIGS. 1a-2b, to facilitate insertion of the shopping cart 12, in a forward movement of the shopping cart 12 into the storage area 14 and prevent the shopping cart 12 to move backward out of the storage area 14, while the mechanical stop 10A is in the upward locked position, as shown in FIGS. 1a, 1b and 2a. For example, the mechanical stop 10A can be a bump that protrudes from the ground 16 or from near the ground 16 when in the locked upward position as shown in FIG. 2a, and is recessed in the ground or near the ground 16 or flush with the ground 16, when in the unlocked downward position as shown in FIG. 2b. The mechanical stop (e.g., bump or protrusion) 10A has a surface 10S that engages mechanically part of the shopping cart 12, such as one or more wheels 12A of the shopping cart 12 to prevent the shopping cart 12 from moving out of the storage area when the bump 10A is in the upward locked position, as shown in FIG. 2a. For example, as depicted in FIG. 1b, the mechanical stop 10A engages the wheels 12A at the back of the shopping cart 12 thus preventing the shopping cart 12 from moving out of the storage area 14.
The mechanical stop 10A may be incorporated into storage area 14. For example, a cross piece may be provided along the ground, across opening 14A. The mechanical stop 10A may be disposed in the cross piece such that the stop 10A protrudes from and is recessed into the cross piece. The cross piece may have a profile that accommodates the stop 10A and allows the shopping carts to move into and out of the storage area. In another example, the mechanical stop may be provided in the ground or in a recess in the ground.
Although the mechanical stop 10A is shown in the FIGS. 1a, 1b, 2a and 2b, as having a triangular or wedge profile shape, as it can be appreciated, the mechanical stop 10A can have other shapes such as a curved shape or trapezoid shape. The main feature of the mechanical stop 10A is to engage part of the shopping cart 12, such as one or more wheels 12A of the shopping cart 12 to prevent the shopping cart 12 from leaving the storage area 14 once the shopping cart 12 is pushed into the storage area 14, when the mechanical stop 10A is in the upward locked position. This feature can be accomplished by providing a steep or abrupt surface 10S of the mechanical stop 10A or by providing a protrusion (e.g., a bump) in the mechanical stop 10A with a sufficient height such that the one or more wheels 12A of the shopping cart 12 cannot overcome the height of the protrusion without lifting the shopping cart 12. The steep surface 10S can be dimensioned such that it engages one or more wheels 12A of the shopping cart 12 to prevent the shopping cart 12 from moving out of the storage area 14.
The mechanism 10 also includes a release mechanism 10B operatively linked to the mechanical stop 10A. The release mechanism 10B is configured to move the mechanical stop 10A from the upward locked position, as shown in FIG. 2a, to the downward unlocked position, as shown in FIG. 2b. In an embodiment, the release mechanism 10B comprises a handle 10C located in or near the storage area 14 near the opening 14A. In an embodiment, the release mechanism 10B is configured to be activated manually to move the mechanical stop 10A from the locked upward position, as shown in FIG. 2a, to the unlocked downward position, as shown in FIG. 2b. The handle 10C may be provided at about waist level or may be operated via a foot pedal.
FIGS. 3a and 3b depict schematically the mechanism 10 for keeping shopping carts 12 within a storage area 14, according to an embodiment of the present disclosure. As shown in FIGS. 3a and 3b, the mechanism 10 includes the release mechanism 10B that is operatively linked to the mechanical stop 10A (e.g., a wedge-like stop). The release mechanism 10B comprises the handle 10C. The release mechanism 10B also comprises a spring board 100 that is moveable to contact the mechanical stop 10A. The spring board 100 includes one or more resilient members 101 (e.g., springs). The spring board 100 is configured to bias the mechanical stop 10A to the upward position when brought in contact with the mechanical stop 10A. The resilient members 101 may be compressed or flex when a shopping cart 12 is pushed into the storage area 14. Thus, the spring board 100 and mechanical stop 10A may move at least partially downward to facilitate to movement of the shopping cart 12 into the storage area 14. The resilient members 101 may be selected to have a resiliency that gives way under the force applied to the shopping cart moving into the storage area 134.
The release mechanism 10B also includes a pivot joint 102 and a first linkage arm 104 that links the pivot joint 102 to the spring board 100. The release mechanism 10B also includes a second linkage arm 106 that links the pivot joint 102 to the handle 10C. In an embodiment, the handle 10C is pivotally connected to a support structure 110 via pivot point 109.
In an embodiment, the mechanical stop 10A is configured to move from the downward unlocked position as shown in FIG. 2b to the locked upward position as shown in FIG. 2a automatically once the shopping cart 12 is removed from the storage area. For example, the mechanical stop 10A can be spring loaded by the spring board 100 including the one or more resilient members 101. The spring board 100 can be arranged to automatically move the mechanical stop 10A from the unlocked downward position to the locked upward position once the shopping cart 12 is removed from the storage area 14. The handle or lever 10C of the release mechanism 10B is linked to the mechanical stop 10A via the second linkage arm 106, pivot joint 102 and the first linkage arm 104. Therefore, actuation of the lever or handle 10C can move the mechanical stop 10A between the upward locked position and the downward unlocked position.
In operation, initially the spring board 100 is in contact with the mechanical stop 10A. Therefore, the mechanical stop 10A is biased to the upper locked position, as shown in FIG. 3a. In this configuration, the handle or lever 10C is in the upper position (activated position). When the handle or lever 10C is in the upper position, as shown in FIG. 3a, the second linkage arm 106 moves downwardly to actuate the pivot joint 102. This movement of the second linkage arm 106 along with the actuation of the pivot joint 102 in turn moves the first linkage arm 104 to pull the spring board 100 towards the mechanical stop 10A. In some embodiments, the spring board includes a top surface 32 that engages with a bottom surface 30 of the mechanical stop 10A. Movement of the top surface 32 along the bottom surface 30 causes the mechanical stop to pivot upward about pivot 34. In other cases, the mechanical stop 10A is simply moved upwards. As a result, the mechanical stop 10A is brought to the upper locked position by the biasing force of the spring board 100. In this position, the mechanical stop 10A engages one or more wheels 12A of the shopping cart 12 to prevent the shopping cart 12 from leaving the storage area 14 once the shopping cart 12 is pushed into the storage area 14, as illustrated in FIG. 1b.
When a user actuates the handle or lever 10C, for example by pulling down the handle or arm 10C, as shown in FIG. 3b, the arm or handle 10C pivots around pivot point 109 and the second linkage arm 106 is moved upwardly to actuate the pivot joint 102. This movement of the second linkage arm 106 along with the actuation of the pivot joint 102 in turn moves the first linkage arm 104 to push the spring board 100 away from the mechanical stop 10A. As a result, the biasing force of the spring board 100 is removed and the mechanical stop 10A is brought to the lower unlocked position. The converse of the above movements of the mechanical stop 10A may occur to lower the mechanical stop 10A. When the mechanical stop 10A is in the downward unlocked position, as shown in FIG. 2b and FIG. 3b, the shopping cart 12 can be pulled out from the storage area 14 without the one or more wheels 12A of the shopping cart being hindered by the mechanical stop 10A. This facilitates pulling out the shopping cart 12 from the storage area 14. For example, this can be performed by an employee of the retail store when retrieving the one or more shopping carts 12 from the storage area 14 to take them back to the retail store to be used again by customers of the retail store.
Although the release mechanism 10B is described in the above paragraphs as having first and second linkage arms 104 and 106 and a pivot joint 102, as it can be appreciated other types of release mechanisms can also be used to control a movement of the mechanical stop 10A. For example, instead or in addition to the linkage-type mechanism depicted in FIGS. 3a and 3b, a gear-type mechanism can also be used. In addition, although the release mechanism 10B is described above as being manually actuated, the release mechanism 10B can also be actuated using a motor.
The term “locked upward position” is used herein to indicate that the mechanical stop 10A when in the upward position is locked in the sense that the one or more wheels 12A when engaging the mechanical stop 10A, the mechanical stop 10A does not move into the downward position as shown in FIG. 2b. The mechanical stop 10A does not move to the downward position shown in FIG. 2b unless the release mechanism 10B is actuated. The term “unlocked downward position” is used herein to indicate that the mechanical stop 10A is unlocked using the release mechanism 10B to put the mechanical stop 10A in the downward position, as shown in FIG. 2b. In an embodiment, as the mechanical stop 10A is unlocked in the downward position, the mechanical stop 10A can also be configured to automatically return to the upward position, for example by using a spring loading device (not shown), or by re-actuating the release mechanism 10B to enable the mechanical stop 10A to return to the upward locked position.
As it must be appreciated from the above paragraphs, there is also provided a storage system 11 for shopping carts 12. The shopping carts storage system 11 includes the storage housing 14 having the opening 14A. The storage housing 14 is configured to store a plurality of shopping carts 12. The storage housing 14 is described in detail in the above paragraphs. The storage system 11 also includes the mechanical stop 10A described in detail in the above paragraphs. The storage system 11 further includes the release mechanism 10B that is operatively linked to the mechanical stop 10A. The release mechanism 10B is configured to move the mechanical stop 10A from the locked upward position as shown in FIG. 2a to the unlocked downward position as shown in FIG. 2b.
The various embodiments described above are provided by way of illustration only and should not be construed to limit the scope of the disclosure. Various modifications and changes may be made to the principles described herein without following the example embodiments and applications illustrated and described herein, and without departing from the spirit and scope of the disclosure.
Although the embodiments of disclosure have been described in detail for the purpose of illustration based on what is currently considered to be the most practical, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present disclosure contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
