DETAILED DISCLOSURE
This written description uses examples to disclose embodiments of the present application, including the best mode, and also to enable any person skilled in the art to practice or make and use the same. The patentable scope of the invention is defined by the claims and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
One area that has continued to provide obstacles for persons with disabilities, particularly persons confined to wheel chair, is interfacing with mounted interface devices, for example, credit card terminals at check-out lanes in retail stores. Many retail stores use credit card terminals at check-out locations for their customers. The terminals are often mounted on check-out counters, and positioned at a height that is convenient for most consumers who are standing at the counters. For persons in wheel chairs, however, who are typically seated in their chairs, and positioned considerably lower than standing customers, the height of the terminals poses considerable difficulties. Such disabled persons often need the assistance of others when paying for the items they have purchased. It is sometimes necessary for others to insert the disabled person's credit card, or to enter private PIN numbers into a terminal. Often times, the only practical way for a person confined to a wheel chair to enter private PIN numbers is for the confined persons to reveal the private code to another person, who physically enters the numbers into the terminal interface.
Despite the widespread need for a device that more fully accommodates physically handicapped persons at these check-out locations, the problem has not been solved. Rather than positioning the payment devices at levels optimal for persons confined to wheel chairs, most stores have elected to position the devices at height levels that are convenient to persons who are physically able to stand at the check-out counters, the number of which greatly exceeds the number of wheel chair-bound customers. As a result, persons confined to wheel chairs have been forced to suffer the inconvenience and security risks of interacting, either directly or with the need for assistance of another person, with non-accommodating payment devices.
Referring now to the drawings, FIG. 1 shows one embodiment of a device 100 in accordance with the present disclosure. Specifically, the carriage 130 is shown removed from the receiver portion 99. The device 100 includes a base 102 having a circular configuration. The base 102 is adapted to be secured to a counter top or another object, for example, at a check-out location for a retail store to anchor the device 100. A columnar support member 104, having a cylindrical configuration in one embodiment, is provided in some embodiments, such as that shown in FIG. 1, but is not required (see FIG. 14). FIGS. 2 and 3 depict front and rear views of the same.
As shown in FIG. 4, the columnar support member 104, may extend upwardly from the center of the base 102. A link 106 having a first end 107a and a second end 107b may be rotatably mounted at the second end 107b to the top end of the columnar support member 104. If the link 106 is incorporated, the link 106 may extend radially outward from the axial center of the columnar support member 104 so that it may be coupled to a rotational assembly 108 at the first end 107a. In the embodiment shown, the rotational assembly 108 includes a first member 109 and a second member 110 that is rotatably attached to the first member 109 about tilt axis A. Other configurations of the rotational assembly 108, however, are contemplated to be within the scope of the present application. In addition, the device 100 provides rotation of the carriage support member 112 relative to the rotational assembly 108 about a twist axis B by virtue of pivot coupler 111 (see FIG. 5), as well as about turn axis C, and are discussed further below.
It should be recognized that the present disclosure also anticipates devices that do not have one or both of a link 106 or a rotational assembly 108. For example, the embodiment shown in FIG. 14 does not include link 106, in addition to not having a columnar support 104 as previously discussed. Likewise, other devices having additional links or rotational assemblies, or other additional structures, are also anticipated by the present disclosure.
Returning to FIG. 4, a carriage support member 112, having a generally rectangular configuration in one embodiment, is coupled to the second member 110 of the rotational assembly 108. In addition to the tilt axis A and twist axis B, the carriage support member 112 is movable relative to the base 102 about a turn axis C via rotation of the link 106 relative to the columnar support member 104. It should recognized that rotation about the turn axis C may also occur as relative movement between the columnar support member 104 and the base 102, such as in configurations where the link 106 and the columnar support member 104 are rigidly coupled, or where no columnar support member 104 is present.
In the embodiment of FIGS. 1 and 4, the carriage support member 112 has an upper section 114 that forms a substantially planar surface. As shown in FIG. 1, a lock aperture 116 extends through a central portion of the carriage support member 112 through both the upper section 114 and a lower section 115 that is opposite the upper section 114. An auxiliary aperture 118 also extends through the carriage support member 112 proximal to one end of the carriage support member 112. As shown in FIGS. 11-12, the auxiliary aperture 118 is configured such that a tether 119 can pass through to tie the interface device 128 to the base 102 or other portions of the device 100, such as to prevent loss or theft. Likewise, a power cord and/or data cable may be passed through the auxiliary aperture 118 to the interface device 128.
In the embodiment of FIG. 1, a release handle 120 is movably coupled to the carriage support member 112. In this exemplary embodiment, the release handle 120 defines a release handle opening 121 that is configured to receive one or more fingers of a user. With this configuration, the user can easily grab the release handle 120 without exerting a grip or pinch force to move the release handle 120 with little effort. This design is preferable by ADA standards.
The release handle 120 may extend from the first end 123a of a lock control member 122. A second end 123b of the lock control member 122, which in the present embodiment also forms a lower locking feature, extends into the carriage support member 112. It should be recognized that in other embodiments, a separate lower locking feature is coupled to or fabricated with the second end 123b. Likewise, the release handle opening 121 may be of a shape, size, or configuration different than the exemplary embodiments shown herein. Moreover, the release handle opening 121 need not be surrounded on all sides by the release handle 120, as shown in the embodiment of FIG. 16C.
As previously described and shown in FIGS. 1 and 6, the carriage support member 112 may be formed of an upper section 114 and a lower section 115 that are secured together by a plurality of screws 124. The upper section 114 of the carriage support member 112 includes a pair of outwardly extending bosses 126 that cooperate with complementary shaped and sized openings on the lower side 131b of a carriage 130 to align the carriage 130 on the carriage support member 112, which is described further below.
Referring now to FIG. 10, an interface device 128, specifically illustrated as a credit card terminal, is shown mounted on the upper side 131a of the carriage 130. FIGS. 11-12 show top and side views of one such an interface device 128 installed on the presently disclosed device 100. One alternative version of an interface device 128 is also shown in FIG. 13, though many others are compatible with the presently disclosed device 100. The embodiment of FIG. 13 uses retention devices 125 to provide or aid in this mounting of the interface device 128 and carriage 130. It should be noted that in the present disclosure, mounting, connecting, coupling, installing, and other synonyms should be interpreted to have the broadest definitions supported.
Returning to FIG. 10, the carriage 130 is shown positioned in close proximity to the upper section 114 of the carriage support member 112. The lower side 131b of the carriage 130 is shown in FIGS. 8-10. These Figures further depict an upper locking feature 132, shown here as a projection extending away from the lower side 131b of the carriage 130. The upper locking feature 132 is sized and configured to fit within the lock aperture 116 when the lower side 131b of the carriage 130 is positioned on the upper section 114 of the carriage support member 112. In the embodiment shown in FIG. 9, one end of the upper locking feature 132 has a slot 134 to engage with a lower locking feature.
In other embodiments, the upper locking feature 132 moveably couples the carriage 130 to the carriage support member 112 without a lower locking feature or lock control member 122 simply through engagement of the upper locking feature 132 and the lock aperture 116.
It should be recognized that while the previously discussed embodiments incorporate a carriage 130 that is distinct from the interface device 128 to be mounted thereon, alternate embodiments may integrally incorporate the carriage 130 into the base of an interface device 128 for more directly coupling the interface device 128 to the carriage support member 112. However, providing a carriage 130 separately from the interface device 128 is advantageous in that the device 100 can then be retrofitted to accommodate a wide variety of existing interface devices 128, reducing the cost of implementing the presently disclosed device 100 to attain ADA-compliance.
In the embodiment shown in FIG. 6, the lock control member 122 is slideably movable between the upper section 114 and lower section 115 of the carriage support member 112 through a pathway defined by guide surfaces 212 on opposite sides of the lock control member 122. The lock control member 122 may also include an internal guide aperture 220 through which a guide structure 222 may extend to guide the direction of the lock control member 112's movement relative to the carriage support member 112. A lock spring 224 may be incorporated to bias the lower locking feature, here the second end 123b of the lock control member 122, into the slot 134 (not shown). This locks the carriage 130 against the upper section 114 of the carriage support member 112. Although the lock spring 224 is shown here to be a spring, other mechanisms for biasing the lower locking feature would be known to those skilled in the art, and are contemplated as being within the scope of the present disclosure.
In other embodiments, such as those shown in FIGS. 16A-16C, the lock control member 122 is moveable in different ways and through different structures. In the embodiment of FIG. 16A, the lock control member 122 is translationally moveable relative to the carriage support member 112 as with the embodiment shown in FIG. 6. However, the embodiment of FIG. 16A provides this translational moveability using a slide notch 240 on the lock control member 122 that moves within a slide groove 242, shown here to be within the lower section 115. Here, a lock spring 224 biases the lock control member 122 into engagement with the upper lock feature 132, such as via a slot 134 therein.
In contrast, FIGS. 16B and 16C provide embodiments whereby the lower locking feature, shown here as the second end 123b of the lock control member 122, is rotatably moveable relative to the lower section 115. In each case, the lock spring 224 biases the second end 123b into engagement with the upper locking feature 132 as previously described.
It should be recognized that while the previous examples primarily focus on the upper locking feature 132 and the lower locking feature, such as the second end 123b of the lock control member 122, engaging by use of a slot 134, other locking structures would be known to those skilled in the art. For example, the lock control member 122 can engage a hole within the upper locking feature 132, the slot 134 could be within the second end 123b of the lock control member 122 instead of within the upper locking feature 132, or other variations, all of which are contemplated as being within the scope of the present disclosure.
Still further embodiments do not incorporate a lock aperture 116 within the carriage support member 112 and lock control member 122, but instead removably couple the carriage 130 to the carriage support member 112 without translational or rotational engagement. In certain embodiments, this includes the use of a first connecting feature and a second connecting feature that are removably engageable in place of the upper locking feature and lower locking feature of other embodiments. For example, the embodiment of FIG. 16D discloses a plurality of magnets 250 coupled to the upper section 114 of the carriage support member 112. The plurality of magnets 250 are configured to magnetically couple with the lower side 131b of the carriage 130. Similarly, FIG. 16E discloses an embodiment having corresponding hook 260 and loop 262 structures on the upper section 113 and lower side 131b for similar, removable coupling therebetween. The embodiments of FIGS. 16D and 16E are advantageous in that the carriage support member 112 does not require guide surfaces 212, slide grooves, or other machined or formed openings between the upper section 114 and lower section 115 to accommodate a lock control member 122. This provides cost savings in producing the carriage support member 112 and by eliminating the need and complexity of a lock control member 122.
As previously described and shown in FIGS. 10-14, the device 100 may support an interface device 128, such as the illustrated credit card reader, in an operative position above a check-out counter. For transactions by persons in a standing position at the counter, the device 100 can be rotated about its tilt axis A, twist axis B, and/or turn axis C, and/or can be moved translationally via the link 106, and/or up and down via an telescoping version of the columnar support member 104 (not expressly shown) to alter the position at the convenience of the consumer (see FIG. 4). As one of ordinary skill would be recognized, the presently disclosed device 100 is also operable with a gooseneck connection between the base 102 and the carriage support member 112 to provide positioning flexibility. The gooseneck connection may be incorporated in place of or in addition to the columnar support member 104, link 106, and/or rotational assembly 108 depending on the particular application and the interface device 128 being used.
In each of these previously discussed embodiments, the carriage 130 and the interface device 128 contained thereon remains separable from the carriage support member 112. In this regard, the device 100 provides that the interface device 128 is moveable to another position off of the receiver 99, for example where it can be used by a consumer sitting in a wheel chair. It should be recognized that using the interface device 128 separately from the device 100 can also be advantageous in other applications, such as drive-thru windows accommodating vehicles of different heights and sizes.
In the embodiment shown in FIGS. 11-13, separation of the carriage 130 and carriage support member 112 is achieved by pulling the release handle 120. Pulling the release handle 120 is operative to slide the lock control member 122, and specifically the lower locking feature formed by the second end 123b, out of the slot 134 in the upper locking feature 132. With the second end 123b removed from the slot 134, an ejection spring 140 (as seen in FIG. 6) urges the carriage 130 away from the upper section 114, as illustrated in FIG. 10. With the lock control member 122 no longer securing the carriage 130 to the carriage support member 112, the carriage 130 and interface device 128 carried thereby becomes movable, for example to the lap of a wheel chair bound consumer. This allows the wheel chair bound consumer to interact with the interface device 128 with far greater convenience than conventional credit card terminals, including allowing the consumer to complete the sales transaction without the assistance of another person.
FIG. 14 shows an interface device 128 mounted in an embodiment of the device 100 resembling a handicap-accessible docking station. The interface device 128 shown is secured to a carriage 130 that is locked to a carriage support member 112 in one of the manners previously described. The release handle 120 may be slidable movable via the slide notch 240 within slide groove 242 in the lower section 115 to disengage the second end 123b or other lower locking feature as shown in FIG. 16A. However, the present disclosure anticipates other configurations for disengaging the second end 123b or other lower locking feature, such as that shown in FIG. 16B with rotational movement about a pivot axis at coupler 246.
As shown in FIG. 15, the interface device 128 has a plurality of interface electrical contacts 230, which contact corresponding fixed electrical contacts 232 on the upper section 114 of the carriage support member 112 (see FIG. 1) to charge the interface device 128 while it is in the docking station. In certain embodiments, such as that shown in FIG. 1, the carriage 130 has an opening 234 to allow contact between the plurality of interface electrical contacts 230 and the plurality of fixed electrical contacts 232. A cable 236 then provides a connection between the plurality of fixed electrical contacts 232 and other external point of sale equipment.
It should be recognized that the plurality of interface electrical contacts 230 and fixed electrical contacts 232 are applicable to any of the previously described embodiments. In this regard, the interface device 128 may either communicate with other point of sale equipment wirelessly, such as using Bluetooth® or NFC technology, or may store transaction information until the interface device 128 is reconnected with the carriage support member 112. Alternatively, some embodiments permit the interface device 128 to be hard-wired to such point of sale equipment with power cords and/or data cables for wireless connectivity. For example, power and/or data may be handled through USB ports located on the device 100 and/or the carriage 130 in place of the plurality of interface electrical contacts 230, and corresponding fixed electrical contacts 232.
In the above description, certain terms have been used for brevity, clarity, and understanding. No unnecessary limitations are to be inferred therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed. The different assemblies described herein may be used alone or in combination with other devices. It is to be expected that various equivalents, alternatives and modifications are possible within the scope of any appended claims.
