Description: METHOD AND APPARATUS FOR SECURING A SHOPPING CART TECHNICAL FIELD The present invention relates to a method and apparatus for securing a wheeled device, and more particularly, to a method and apparatus for securing a shopping cart. BACKGROUND ART When shopping at a retail establishment, a customer often wishes to obtain or purchase a number of goods. The customer may not be able to carry all of the goods to the check-out area or to their car. In order to alleviate this problem, many retail establishments provide shopping baskets or carts. A problem with baskets is that the customer still must carry the basket while shopping. If the customer shops for a long period of time or if a number of goods are purchased, the customer may find it uncomfortable if not impossible to carry the basket and goods. Wheeled shopping carts provide a storage area for the goods a customer wishes to purchase and makes it easy for the customer to transport the goods. A customer pushes the cart about the establishment, placing goods in the cart along the way. Ultimately, the customer pushes the cart to a check-out or purchase point. Once the goods have been paid for, the customer normally still needs a convenient means to transport the goods from the establishment, such as to their car or home. The parking areas of many establishments are often quite large and the distance from the check-out area of the establishment to a customer's car may be quite far. Usually, the retail establishment permits the customer to utilize the cart for this purpose. After purchasing their goods, customers may push the loaded cart from the establishment over a parking area to their car. The customer then unloads the goods from the cart. A problem now arises in that the cart is located outside of the establishment. Most customers are unwilling to push the now empty cart back into the retail establishment, and thus the cart is left in the parking area. Because the cart is wheeled, once left unattended the cart may roll about the parking lot. Wind and gravity may cause the cart to roll at various speeds and directions. The unattended or "runaway" cart as such carts are often referred to may roll away and be lost by the retail establishment, at great cost to the establishment. Moreover, the carts may cause injury and damage. For example, the cart may roll into a vehicle parked in the parking lot and damage it. The carts may also roll into moving traffic or into pedestrians, also causing damage and injury. Because of the rather high incidence of damage caused by unattended carts, but not wishing to take away the convenience of providing the carts to customers, many establishments post signs warning that damage from run-away and unattended carts may cause damage and stating that the establishment is not responsible for damage thereby. Nonetheless, retailers often have many claims filed against them every year arising from runaway cart damage and injury. As one attempt to alleviate the above-stated problems, some establishments have created cart return areas in their parking areas. These areas generally comprise an area closed on two or more sides by fence-like structures. It is intended that once a customer is done using a cart, the customer will roll the cart to one of the semi-enclosed cart return areas. There are several problems with this attempted solution. The apparatus comprising the cart return normally comprises a tubular aluminum or other metal structure. The structure may be quite large and relatively expensive. The cart return areas normally consume several parking spaces in the parking area. Because of the size and cost, an establishment may only provide one or two cart returns in their parking area. Because of the limited number of cart returns and the likelihood that a cart return may still be a significant distance from a customer's car, many customers still do not return their carts. In addition, the configuration of the cart return does not ensure that those carts which are returned are secured. The semi-enclosed nature of the return permits customers to push the carts into the return area. The carts are generally secured by being prevented from rolling away by engaging a portion (such as a long horizontal rail) of the cart return structure. Because one or more portions of the cart return are open and the wheels of the returned carts are not engaged, one or more carts may still roll out of the cart return area and into the main area of the parking lot. Some security devices have been proposed to prevent customers from removing carts from the area of an establishment. Some of these devices are arranged to lock one or more wheels of the cart. Such devices are intended to prevent the theft or negligent removal of carts and are not useful in solving the above-stated problem. First, these devices generally are arranged to "trigger" when the cart reaches an outer perimeter beyond which the customer is not permitted to travel with the cart. It is not feasible to arrange such a device to trigger once a cart is left unattended at any particular point in a parking lot to prevent the cart from rolling away once unattended. Once the lock is triggered, store/owner personnel must reset the lock in order for the cart to be useful. It is also not feasible to have an arrangement where once a cart is left unattended, such as in a parking lot after use, a lock is triggered which must be reset in order for the cart to be reused. This arrangement would cause substantial time and money loss in resetting the locks. A method and apparatus for securing a cart which overcomes the above-stated problems is desired. SUMMARY OF THE INVENTION The present invention is a method and apparatus for securing a shopping or similar wheeled cart. In accordance with one embodiment of the invention there is provided a cart securing structure for securing a cart having at least one wheel. The cart securing structure comprises a body having a bottom surface for engaging a support surface and a top surface defining at least one first stop having a first face and a second face. The first face slopes upwardly from the bottom surface towards the rear face and defines a leading edge positioned near the support surface. The stop includes an apex provided between the first and second faces, the second face sloping downwardly from the apex. At least one securing element is provided for securing the cart securing structure to a support surface. In a method of use, one or more wheels of a cart are rolled upwardly along the sloping first face of the stop. The one or more wheels are rolled over the apex and into engagement with the second face, preventing the cart from rolling away once unattended. In accordance with another embodiment of the invention the cart securing structure includes a first stop and a second stop having a trough positioned therebetween for accepting at least one wheel of the cart between the first and second stop. The first stop has a first face sloping upwardly from the bottom surface over which a wheel of the cart may be rolled and a second face sloping downwardly towards the trough for engaging the wheel of the cart to prevent the cart from rolling away. The second stop has a first surface sloping upwardly from the trough for engaging a wheel of the cart to prevent the cart from rolling away. In accordance with one or more embodiments of the invention, the cart securing structure includes a cover associated with the front face of a first stop. The cart securing structure may also include side members and/or upwardly extending markers. One or more embodiments of the invention comprise a method of securing a cart securing structure of the invention to a support surface. In one method, the method comprises bolting the structure to the support surface. The structure may include one or more bores through which a fastener may pass for this purpose. In another method, the structure is secured to the support surface with adhesive. The structure may include one or more outwardly extending pins for orienting the structure. Further objects, features, and advantages of the present invention over the prior art will become apparent from the detailed description of the drawings which follows, when considered with the attached figures.

DETAILED DESCRIPTION OF THE INVENTION The present invention is an apparatus and method for securing a wheeled device such as a shopping cart. In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention In general, the apparatus of the invention comprises a cart dock and a method of use which are particularly adapted to securing a wheeled cart. Such carts are well known. In general, carts known as "shopping carts" found at groceries and similar retailers comprise a frame structure supporting a basket in which goods may be placed. The frame is generally constructed of metal, while the basket may be constructed of metal or plastic. The frame structure is rollably supported by four (4) wheels 41 (one of which is illustrated in Figure 2). The four wheels are arranged with two (2) wheels provided at a front portion of the cart and two (2) wheels provided at a rear portion of the cart. The front wheels are generally pivotally mounted for steering the cart. The front wheels are generally spaced about 8-11 inches apart, while the rear wheels are generally spaced about 18-21 inches apart. Each wheel generally comprises a rubber tire mounted on a metal hub, the overall diameter of each wheel generally being about 5 inches. Of course, the particular dimensions of the carts and their arrangements may vary. For example, as described below, the apparatus of the present invention is useful with flat-bed and other carts. Such carts are commonly found at lumber yards and the like. These carts may have front and rear wheels separated by a much larger distance than the above-described carts. The wheels of these carts may also be larger. Referring first to Figure 1 , a first embodiment of a cart dock 20 of the invention comprises a body having a bottom surface 22 (see Figure 4) and a top surface 24. The body includes a first stop 26 and a second stop 28 spaced from one another. The first stop 26 has a first or front face or surface 30 and a second or rear face or surface 32. The second stop 28 has a first or front face or surface 34 and a second or rear face or surface 36. The front face 34 of the second stop 28 faces the rear face 32 of the first stop 26. The front face 30 of the first stop 26 comprises a surface which slopes and/or angles upwardly from the bottom surface 22. The intersection of the bottom surface 22 with the front face 30 of the first stop 26 defines a leading edge 38. Preferably, the leading edge 38 is positioned near a support surface when the cart dock 20 when the cart dock 20 is mounted for use. The front face 30 is sloped rearwardly towards the second stop 28 for accommodating the rolling of a shopping cart wheel 41 upwardly the front face 30. In the arrangement illustrated in Figure 1, the front face 30 is curved. The first stop 26 has an apex 40 formed between the front face 30 and rear face 32. The apex 40 is preferably somewhat rounded to facilitate the rolling of a wheel 41 of a shopping cart thereover. The rear face 32 is positioned generally opposite the front face 30 and slopes downwardly from the apex 40. The slope and shape of the rear face 32 is selected to make difficult the passage of a wheel 41 of a shopping cart in the direction towards the front face 30. In other words, the first stop 26 is configured to easily permit a wheel 41 of a shopping cart to be rolled over the front face 30 towards the rear face 32, but to generally prevent movement of the wheels in the reverse direction. In this regard, in the arrangement illustrated, the rear face 32 of the first stop 26 is somewhat concave, defining a recessed area 42 for accepting a portion of a wheel 41 of a shopping cart. In the arrangement illustrated, it is desirable for the front face 30 to have a slope which is less than the slope of the rear face 32 (ex. average front face slope 60 degrees and average rear face slope of 80 degrees). The front face 34 of the second stop 28 is also arranged to make difficult the rolling of a wheel 41 of a shopping cart thereover. In this regard, the front face 34 rises upwardly and has a slope and shape somewhat similar to the rear face 32 of the first stop 26. The second stop 28 has an apex 44 formed between the front face 34 and rear face 36. The apex 44 is preferably somewhat rounded to facilitate the rolling of a wheel 41 of a shopping cart thereover. The rear face 36 of the second stop 28 is generally located opposite the first face 34 and slopes downwardly from the apex 44. In the embodiment illustrated, the rear face 36 comprises a generally vertically extending wall. The rear face 36 may be sloped at other than a ninety (90) degree angle. In general, it is preferable for the rear face 36 to have a shape which deters a user from rolling a wheel 41 of a shopping cart thereover in the direction of the first stop 26. When the rear face 36 is generally vertical, this is effectuated. A trough 46 is defined between the first stop 26 and the second stop 28. In the area of the trough 46, the top surface 24 of the dock 20 is closer to the bottom surface 22 than the apex 40 of the first stop 26 and the apex 44 of the second stop 28. The trough 46 preferably has a width or distance between the front face 34 of the second stop 28 and the rear face 32 of the first stop 26 to permit placement of a wheel 41 of a shopping cart therein. In the embodiment illustrated, the body has to opposing ends 47a,b and both stops 26,28 and the trough 46 extend the length of the body from end 47a to end 47b. This arrangement is desirable since it permits a user to push a cart into engagement with the dock 20 at any point along the dock 20. In one or more embodiments, where the wheel 41 of the shopping cart with which the dock 20 is to be used is approximately five (5) inches in diameter, the dock 20 has the following dimensions: height of the apex 40 from the bottom surface 22, approximately three (3) inches; height of the apex 44 from the bottom surface 22, approximately one and one-half (1.5) inches; and the distance between the first and second stops 26,28 approximately eight (8) inches. Preferably the width of the dock 20 from end 47a to end 47b is sufficient to accommodate both the front and/or back wheels 41 of a shopping cart. For example, in the case where the front wheels of a shopping cart are spaced by about 8-11 inches, then the width of the dock 20 may be about twenty (20) inches. Such a width is common for shopping carts provided at grocery stores. In the case where the front wheels of a shopping cart are spaced by a greater distance, the width of the dock 20 may be about thirty (30) inches. The greater width dock 20 may be advantageous in accommodating flat-bed and similar high capacity carts provided at some establishments, such as lumber yards. One or more mounting elements are provided for securing the cart dock 20 to a mounting or support surface. The support surface may comprise an asphalt or cement parking lot or any of a variety of other surfaces where a cart is used and where it is desirable to secure the cart. Referring to Figures 5(a) and (b), when the cart dock 20 is to be secured to a paved or other hard surface (such as concrete, rock, asphalt, tile or the like), the mounting elements may comprise anchors 50 and bolts 52. The anchors 50 are placed in bores in the support surface. The bolts 52 then engage one or more portions of the dock 20 and an anchor 50, securing the dock 20 to the support surface. In the arrangement illustrated in Figures 1-4, the cart dock 20 has nine (9) bores provided therein through which a bolt 52 or similar threaded fastener may extend. Three (3) bores 54a are provided in spaced relation through the trough 46 portion of the dock 20 near the second stop 28. Three (3) bores 54b are provided in recessed areas 57 provided in the front face 30 of the first stop 26. Three (3) bores 54c are provided in association with key-ways 56 provided in the bottom surface 22 of the dock 20 generally beneath the first stop 26. The bores 54a provided in the trough 46 portion are generally cylindrical for passage of a bolt 52 therethrough. The recessed areas 57 comprise narrow openings having a generally flat surface through which the bores 54b extend. Each bore 54c is associated with a key-way 56 having an adjoining narrow slot. The cart dock 20 may be constructed in a variety of manners and from a variety of materials. Preferably, the dock 20 is constructed of a durable, weather-resistant material and a material which has a "memory" in that it retains it shape. Because of the use environment of the dock 20, the dock 20 may be driven upon by vehicles. It is desirable for the dock 20 to be flexible enough to yield and both not break or cause damage to a vehicle, and at the same time return to its original shape to function effectively. In one or more embodiments, the dock 20 may be injection molded of a polypropylene or similar material. If the dock 20 is injection molded, the dock 20 may be made hollow to reduce its weight and cost. In such event, one or more ribs or reinforcing structure may be provided (such as inside the hollow areas of the dock 20) for strengthening it. To make the dock 20 readily visible at night, the dock 20 may be made to reflect and/or transmit light. In one arrangement, a reflective and/or light emitting material, such as a coating, may be provided on the dock 20. In another arrangement, the material may be added to or comprise a part of the material which forms the dock 20 (i.e. such as added into plastic when molded). The dock 20 may be made in a variety of colors. In one or more embodiments, the cart dock 20 includes a face cover 48, as illustrated in Figures 1 and 2. The cover 48 is associated with the front face 30 of the first stop 26. In one embodiment, the cover 48 comprises a relatively flexible synthetic material which is approximately the same size and shape as the front face 30 of the first stop 26 (i.e. in this case, curved). As illustrated, the cover 48 may be removably mounted to the dock 20 with a tab which engages a small groove in the front face 30 of the first stop 26. The cover 48 may be removable attachable with hook and loop type fasteners, snaps, or other means well known to those of skill in the art. In one or more arrangements, the front face 30 may have an inset or depressed area for accepting the cover 48. This arrangement has the advantage of inlaying or insetting the cover 48 into the surface 30 in a manner which aids in protecting the cover 48 (such as by preventing the cover 48 from being caught in the wheels 41 of a cart). In one embodiment, the cover 48 comprises a generally transparent material having a reflective or light transmitting material associated therewith (one such material is known as "day-glow"). In this manner, the cover 48 is illuminated at night or reflects light when a headlight of an automobile shines thereon, making the dock 20 readily visible. The cover 48 may also have printing thereon. The printing may comprise advertising or instructions. Because the cover 48 is removable, new advertising or announcements may be provided on the dock 20 at various time intervals. In accordance with one aspect of the invention there is provided a method of mounting the cart dock 20. In accordance with the method, bores are provided in the support surface. The bores may be drilled or may be provided when the surface is constructed (such as when pouring concrete). An anchor 50 is provided in each bore. A bolt 52 is connected to each anchor 50 associated with the three bores 54c. The dock 20 is placed on the surface with these three bolts 52 extending through the bores 54c of the key-way 56. The dock 20 is then moved horizontally, sliding the bolts 52 along the slot portion of the key-ways 56 so that these three bolts 52 engage the slots of the key ways 56. Bolts 52 are then passed through the bores 54a, 54b (from the top side of the cart dock 20) into the associated anchors 50. There may be a greater or lesser number of fasteners used to secure the cart dock 20. In one or more embodiments, a cart dock 20 is provided in association with individual parking stalls of a parking lot. For example, the dock 20 may be secured to the support surface at a front corner of each marked parking stall. In accordance with an embodiment of the invention, there is provided a method of using the cart dock 20. Referring to Figures 1 and 2, when a user/customer has completed using a cart, the user pushes the cart to the dock 20 (such as at the front of their car at the front of the parking stall). The user pushes the front wheels 41 of the cart up the front face 30 of the first stop 26. The wheels 41 roll over the apex 40 and into the trough 46 between the first and second stops 26,28. At this time, the cart is secured and the customer need not attend to the cart further. The front wheels 41 of the cart are secured between the first and second stops 26,28. Referring to Figure 3, in one or more embodiments, the dock 20 may include side members 58. The side members 58 may comprise thin plate-like members which are attached to each end 47a,47b of the dock 20. The side members 58 may be removable attachable, such as with snaps, screws or other means well known to those of skill in the art. The dock 20 may also be constructed with the side members 58 as integral (such as during a molding process). In general, the side members 58 are arranged to prevent the wheels 41 of a cart from rolling out of the trough 46 along its length (i.e. at ends 47a,47b). The side members 58 may be especially useful when a dock 20 is used on a support surface which is sloped in a direction parallel to a length of the dock 20 from end 47a to end 47b. As also illustrated in Figure 3, in one or more embodiments, the dock 20 may include one or more upwardly extending markers 60. Each marker 60 may comprise a flexible plastic, fiberglass or similar pole. Each marker 60 may be constructed of a variety of materials and be of a variety of sizes. Each marker 60 may be arranged to be press fit into a bore provided in the top surface 24 of the dock 20. The markers 60 may be useful in identifying the location of the cart dock 20, such as when a layer of snow covers the cart dock. To make the markers 60 more visible, they may be constructed from or have a reflective material associated therewith. The dock 20 may have other dimensions and shapes than described above. For example, if being used with carts having bigger diameter wheels, first and second stops 26,28 may be taller. When the dock 20 has sides, the dock 20 may be molded, generally having a block-like form with a slanted or sloped front surface leading to a top surface having a trough formed therein. The trough may be positioned between (i.e. not extending the full length between) opposing ends 47a,b of the dock 20, thereby forming an enclosed area for retaining the wheels 41 of the cart. The means for securing the cart dock 20 to a support surface may comprise other than the anchors 50 and bolts 52. For example, other threaded fasteners such as screws (such as when the dock 20 is being secured to a wooden support surface) may be used. The cart dock 20 may be staked to the support surface. One or more spikes or similar elements may be arranged to protrude from the bottom surface 22 of the dock 20 and be driven into the support surface. As described in detail below with reference to the embodiment of the invention illustrated in Figures 10-12, the cart dock 20 may be glued or otherwise adhered to the surface. In this arrangement, no bores need to be provided through the body of the cart dock 20 for the fasteners. If sufficiently weighted, the cart dock 20 may be secured to the support surface with gravity. For example, the cart dock 20 may be filled with water. To improve the adherence of the cart dock 20 to the support surface, the bottom surface 22 may be specially configured. For example, the bottom surface 22 may have ridges or another high-friction configuration. The dock 20 as described above has many advantages. The cart dock 20 is effective in retaining an unattended shopping cart in a fixed position. Unlike cart "corrals," the wheels of the cart are engaged and prevent the cart from rolling away. Unlike wheel locks, the cart is simply unsecured by rolling its wheels out of engagement with the cart dock 20. Because of its size and configuration, a cart dock 20 can be associated with many, if not every, parking space of a parking lot (i.e. such as a front left or right corner of each marked parking spot). In this manner, a cart dock 20 is conveniently provided next to every cart user's cart. This increases the likelihood that a cart user will return the cart to the cart dock 20 and render it secure. Numerous cart docks 20 can be provided at less cost than a single cart "corral" of the prior art. Cart docks 20 can be placed in alignment at the front corner of each parking spot and in such a manner constitute visual "dividers" for the lot. This makes it easier for a customer to navigate the parking lot and may reduce the possibility of customers driving randomly through parking lots and causing accidents with vehicles operated within the marked lanes. As may be appreciated, many drives do not follow parking lot painted markings. However, such drivers may be less inclined to cross the painted markings and drive randomly if such also causes them to have to drive over one or more cart docks 20. Because of the ease of using the cart dock 20, damage and injury caused by runaway unattended carts may be reduced. The reduced financial losses associated with lost carts and other damage and injury is beneficial to the establishment and may even pay for the cart docks 20. Referring to Figure 6, a dock 120 in accordance with a second embodiment of the invention will be described. In accordance with this embodiment, the dock 120 has a single stop 126. The stop 126 has a front face 130 and a rear face 132. The single stop 126 is preferably shaped similar to the first stop 26 of the embodiment illustrated in Figure 1. The front face 130 is sloped and arranged to permit the wheel(s) of a cart to be rolled thereover. The rear face 132 is arranged to engage the wheel of a cart to prevent it from rolling. The embodiment of the cart dock 20 illustrated in Figure 1 where the trough 46 extends from end 47a to end 47b has the advantage that water and other material and debris is not retained or trapped in the dock 20. As may be appreciated, this is advantageous since it is undesirable for the cart wheels to be placed into standing water and the like. Further, the water could become stagnant and contaminated. In the arrangement of the invention where the trough 46 does not extend from end to end 47a,47b or side members 58 are provided, it is desirable to provide one or more drains or outlets through which water and other material may be routed away from the dock 20. As illustrated, the stops 26,28 and trough 46 are longitudinally extending from end to end 47a,47b of the dock 20. The stops 26,28 and trough 46 generally define planar, solid uninterrupted surfaces for contacting the wheels 41 of a cart (preferably, the recessed areas 57 are narrower than the width of the wheel of a cart). The elongate nature of the stops 26,28 and trough 46, as stated above, makes it easy for the user to dock a cart, since the user does not have to "line-up" the wheel of the cart with a specific area of the dock 20. The user may roll a cart into engagement with the dock 20 anywhere along its length. In face, a user may secure a cart by engaging just one (1) of the wheels of a cart. A user can secure a cart by engaging the rear wheel(s) of the cart instead of the front wheel(s). Further, though not desirable (since the cart may then protrude into a portion of an adjoining parking space or the like) a user may secure a cart by rolling the wheel(s) 41 of a cart over the second stop 28 and into engagement with the trough 46. In this embodiment, the dock 120 includes two rows of bores 154b, 154c for mounting the dock 120 to a support surface with anchors 150 and bolts 154. The dock 120 also includes a removable cover 148. The cart dock 120 of this embodiment of the invention may be similarly sized as the cart dock 20 illustrated in Figure 1. The cart dock 120 may also be mounted to a support surface in a variety of configurations and be configured and constructed from and in the variety of manners described with respect to the cart dock 20. The cart dock 120 may include side members and/or markers as described above, as well as a front cover 148. In a method of use of this embodiment cart dock 120, a user rolls one or more wheels of a cart upwardly along the front face 130 of the stop 126. The user rolls the one or more wheels over the apex 140 and permits the one or more wheels to engage the rear face 132 of the stop 126. Once engaged, the cart is secured. As may be appreciated, when a cart is to be secured on a very sloped surface, use of the cart dock 20 is most effective in securing the cart since the one or more wheels of the cart are prevented from rolling in both the forward and reverse directions. If the cart dock 20 is used on a sloping surface, it is desirable to secure the cart dock 20 so that the rear face 132 of the stop 126 faces up the slope, and so gravity tends to pull the wheels of the cart into engagement with the rear face 132 of the stop 126. This embodiment of the cart dock 120 may be less expensive and complex to manufacture. Because of its reduced size and weight, this embodiment dock 120 may also be less expensive to ship. Another embodiment of cart dock 220 is illustrated in Figures 10-12. This embodiment cart dock 220 is similar in many respects to the cart dock 20 in overall configuration and method of use. The cart dock 220 includes a body having a bottom surface 222, top surface 224, first stop 226 and second stop 228. In this embodiment of the invention, a first or front surface 230 of the first stop 226 comprises a surface having a fixed, single slope (i.e. not curved, but flat angled). The second or rear surface 232 of the first stop 226 comprises a generally vertically extending ledge. Similarly, the front or first surface 234 of the second stop 228 comprises a generally vertically extending ledge or wall. The cart dock 220 includes means for securing the body to a support surface. In this embodiment, the means comprises one or more pins 260 which extend from the bottom surface of the body. As illustrated, there are four pins 260, one pin each provided at a corner of the body. Each pin 260 is preferably tapered and extends about one-half to three (.5 to 3) or more inches outwardly from the body. Preferably, this embodiment cart dock 220 is secured to a support surface with an adhesive. When the cart dock 220 is to be secured to a concrete, asphalt or similar surface, the adhesive may comprise a hot-set latex/asphalt type adhesive. Of course, other adhesive materials may be used, including glues and the like. It is also possible to secure this embodiment cart dock 220 to a surface with other than adhesive, such as described above. In order to improve the adherence of the cart dock 220 to the support surface, the bottom surface 222 includes a number of ribs 262. The ribs 262 may comprise elements which provide reinforcement for the body when the body is molded and partially hollow. The spaced arrangement of the ribs 262 creates recessed areas therebetween in which adhesive may flow, providing better adhesion of the dock 220. In the area of the trough 246, the ribs 262 preferably extend outwardly sufficient to create recessed areas. The bottom surface 222 may include one or more pads 266 for providing solid support for the body. As illustrated, the flat pads 266 are provided adjacent the pins 260 and in one or more areas between the pins. It will be appreciated that the cart dock 120 may be similar configured to the cart dock 220, such as by having a generally planar sloping front face, one or more pins extending outwardly for use in securing the dock 120 or the like. In a method of securing this embodiment cart dock 220, bores are preferably provided in the support surface, the bores sized to accept the pins 260. The bores may be provided with a drill or the like using a template of the pin positions. The adhesive may then be placed on the support surface and the bottom surface 222 of the body. The pins 260 of the cart dock 220 are then inserted into the bores, properly positioning the cart dock 220 in the desired location and adhering it to the support surface. In accordance with this method of securing the dock 220 and its configuration, no recesses (for providing access to fastener insertion holes) need to be provided in the front face of the first stop 226. This makes construction of the dock 220 simpler and renders the front face a more contiguous surface over which cart wheels may be rolled. In order to reduce the space occupied by multiple units of the cart dock 220 when being shipped and/or stored, one or more bores 264 may be provided in or through the top surface 224 of the cart dock 220 for mating engagement with the pins 260 of an adjacent cart dock 220. The bores 264 are preferably arranged to accept the pins 260 of a cart dock 220 which is positioned thereabove. In this manner, the cart docks 220 may be stacked vertically in a manner which reduces the total vertical stacking height. In order to prevent water from filling the bores 264, one or more drain holes, slots or the like may be provided through the pins 260. The stacking bores 264 may be arranged to accept a marker (see Figure 2). The depth and size of the bores 264 may vary dependent upon the desired stacking heights, sizes of the pins 260 and markers and other factors which will be appreciated to those of skill in the art. An advantage of this embodiment cart dock 220 is that a flat face cover (not shown, but similar to cover 48 illustrated in Figure 1) may be provided for positioning on the front face 230 of the first stop 226. As illustrated, small bores 268 may be provided for accepting pins or other protrusions (not shown) of the cover. This permits covers to be selectively attached and removed. Because the cover may be constructed flat, its manufacture may be simplified, as may be printing on it. It will be understood that the above described arrangements of apparatus and the method therefrom are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
