Description

BACKGROUND OF THE INVENTION

[0001] Barcode and other scanning devices generally capture images within a given field of view (FOV). In some cases, barcode readers are known to be used in multi-mode environments where, in addition to a presentation mode (where a product is presented to the reader and the reader activates an imaging unit), the same reader can also be used in a handheld mode. Therefore, there are various situations where the reader needs to be held and moved, or it may be preferable to place the reader on a stable surface such as a table or work surface.

[0002] DE 197 81 569 B4 describes data reading devices such as scanners and barcode readers. In particular, it describes barcode readers that can be used for stationary and handheld scanning applications, employing different scan patterns for stationary and handheld operation. Each scan pattern is optimized for the corresponding operating mode to avoid the performance degradation that occurs when using a single scan pattern for both modes.

[0003] Accordingly, there is a need for improved accessories with enhanced functionalities. BRIEF DESCRIPTION OF THE DIFFERENT VIEWS OF THE DRAWINGS

DETAILED DESCRIPTION

[0007] According to the invention, a barcode reader assembly with the features of claim 1, an accessory base with the features of claim 10, and a barcode reader assembly with the features of claim 17 are provided. Exemplary embodiments are described in the dependent claims. In one embodiment, the present application provides a barcode reader assembly for detecting at least one object appearing in a field of view (FOV), comprising a reader and a frame. The reader comprises a reader housing with an upper section and a lower section, and a reader base with a curved base surface. The lower section of the reader housing is mechanically coupled to the reader base. The frame comprises a platform and a wall that generally extends upwards from the platform. The reader base is mechanically coupled to the frame so that the reader is rotatable relative to the frame.

[0008] In some aspects, the reader base is coupled to the platform via a mechanical connection. The mechanical connection may include an elastic finger component with a projection extending from it. The elastic finger may be supported by at least one of the reader bases or the platform. This projection may be in the form of an angled side wall that rotatably engages in a connection opening. In some examples, at least one of the angled side wall or the connection opening includes at least one detent to selectively limit relative rotation of the reader within the frame. In some of these examples, the mechanical connection interacts with the frame wall to limit relative translational movement between the reader and the frame.

[0009] In some designs, the platform may additionally include a mounting mechanism for attaching the frame to a display surface. This mounting mechanism may take the form of a through-hole. The mechanical connection may also include a decoupling element to isolate the reader from the frame. This decoupling element may be integrated into the elastic finger component.

[0010] In some designs, the wall may contain an opening sized to accommodate a connecting cable attached to the reader. In some examples, the wall includes an opening to accommodate a section of the reader base.

[0011] In another implementation, an accessory base for a barcode reader for capturing at least one image of an object appearing in a field of view (FOV) comprises a platform with a perimeter, a wall extending upwards from the platform generally around its perimeter, and a mechanical connection formed by the platform. The mechanical connection includes an elastic finger component with a projection extending from it.

[0012] In another implementation, a barcode reader assembly for capturing at least one image of an object appearing in a field of view (FOV) comprises a reader and a frame. The reader includes a reader housing with an upper and a lower section. The reader base includes a curved base surface. The lower section of the reader housing is mechanically connected to the reader base. The frame includes a platform and a curved wall that generally extends upward from the platform and is mechanically coupled to the reader base so that the reader is rotatable relative to the frame. When the reader is mechanically coupled to the frame, the curved base surface of the reader base and the curved wall of the frame are interlocked such that a gap of less than approximately 5 mm is formed between the curved base surface and the curved reader housing surface.

[0013] With reference to the figures, reference number 10 generally identifies a barcode reader assembly comprising a reader 11 in the form of an egg-shaped housing with a base 12 and a reader housing 30 mechanically connected to the base 12. As used herein, the term barcode may refer to one- or two-dimensional barcodes and / or other symbologies used to encode information associated with objects. The reader assembly 10 further includes a frame 50 to which the base 12 is selectively coupled.

[0014] The base 12 comprises an upper section 12a and a lower section 12b. The upper section 12a of the base 12 comprises a curved base surface 14 that extends over its perimeter. As in Fig. As shown in Figure 6, the lower section 12b of the base 12 contains a connecting opening 16 located at or near a central point of the base 12. As explained in more detail below, this connecting opening 16 interacts with a pivot axis of the frame 50 around which the barcode reader 11 rotates. The base 12 can be made from any number of suitable materials, such as polymers and / or metallic materials. Other examples are possible.

[0015] The reader housing 30 is mechanically coupled to the base 12 (e.g., via a mechanical connection). The reader housing 30 is defined by a housing body 32, which has an upper section 32a, a lower section 32b opposite the upper section 32a, a front section 32c, and a rear section 32d opposite the front section 32c. The front and rear sections 32c, 32d of the housing body 32 can be in the form of front and rear housings or shell elements, which can be joined together in an operational manner by any number of suitable attachments (e.g., fasteners, friction and / or slot engagement elements, etc.).

[0016] In the illustrated example, the lower section 32b of the housing body 32 is positioned near the base 12 and defines a curved reader housing surface 34. In the illustrated example, the curved reader housing surface 34 is generally spherical and nests within the upper section 12a of the base 12. The housing body 32 further defines a rear cutout for receiving an external data and / or power cable 36. Generally, the reader housing 30 is rotatable relative to the base 12 about an axis “A” via a mechanical connection supported by the reader housing 30 or the base 12. In particular, US 2020 / 0226330A1, filed on January 11, 2019, describes industrial digital barcode readers with specific mechanisms that allow relative movement (e.g., rotation) of components. The entire contents of that application are incorporated herein by reference. As in Fig. As shown in Figure 2B, the reader housing 30 rotates about the axis A, which is depicted as orthogonal to the cross-section. The mechanical connection can include a ratchet projection 18 that defines any number of ratchets or detents 22 to allow selective positioning of the reader housing 30 relative to the base 12. A section of the housing body (e.g., the rear section 32d) additionally defines a pawl bore 40 for receiving an elastic element (e.g., a spring) 42 and a pawl element 44. The elastic element 42 forces the pawl element 44 into engagement with the ratchet projection 18, whereupon the pawl element 44 can selectively engage in and / or be held in a desired detent 22.

[0017] The elastic element 44 generates a force that resists a pushing or rotating force applied by a user to the housing body 32 until the pushing force exceeds the engagement force between the detent 22 and the pawl element 44. At this point, the relative rotation between the pawl element 44 and the ratchet projection 18 causes the pawl element 44 to move into an adjacent detent 22 and be held therein until a pushing force applied by the user again exceeds the engagement force between the detent 22 and the pawl element 44. As a result, the housing body 32 can be selectively held at a desired angle or in a desired configuration relative to the base body 12.

[0018] In the illustrated example, the frame 50 comprises a platform 52 and a wall 54 that generally extends upwards from the platform. The platform 52 has a generally circular base corresponding to the shape of the base 12 and comprises a top 52a, a bottom 52b, a front 52c, and a back 52d. The wall 54 extends upwards from the top 52a of the platform 52 and is located at its front 52c. The wall 54 has a generally curved shape corresponding to the shape of the platform 52 and terminates at a point between the front and back 52c, 52d of the platform 52. In the illustrated example, the wall terminates approximately at a midpoint between the front and back 52c, 52d of the platform 52, and as such, the wall 54 has a generally semicircular (e.g., hemispherical) shape in plan view. Other configurations are possible.

[0019] The wall 54 extends upwards to a height approximately equal to the height of the base 12 in order to limit potential interference with the reader 30 when the reader 11 is coupled to the frame 50. Furthermore, the wall 54 is designed with particular reference to Fig. 4 is angled so that it runs inwards, i.e., a cross-sectional dimension D1 at the top of the wall 54 is smaller than a cross-sectional dimension D2 at the bottom of the wall 54 and below the cross-sectional dimension D1. The frame 50 can be made of any number of suitable materials, such as polymers and / or metallic materials. Other examples are possible.

[0020] In a preferred embodiment, a top-to-bottom cross-section of the base 12 around the wall 54 has a radius extending from the axis L to the front section of the base 12 (i.e., to the inner edge of the wall 54) and is equidistant throughout the entire cross-section. In other embodiments, the radius extending from the axis L to the front section of the base 12 may be larger than a radius extending from the axis L to the rear section of the base 12.

[0021] The frame 50 can additionally include any number of fastening structures 56, which serve to attach the frame 50 to an object such as a table, a cash register, a desk, or any other component. In the illustrated example, the fastening structure 56 has the form of a hole or through-hole that accommodates a fastener (e.g., a screw or a bolt), but in other examples, other devices such as adhesives, hook-and-loop fasteners, and the like may also be used.

[0022] The platform 52 of the frame 50 further supports a mechanical connection in the form of an elastic finger 60. In the illustrated example, this elastic finger 60 is formed by a cutout 55 that is formed on the platform 52 and extends from the rear 52d to the front 52c thereof. In the illustrated example, the cutout 55 comprises an elongated and a generally circular section, but other example shapes or arrangements of the cutout 55 are possible. A proximal end 60a of the elastic finger 60 is coupled to and / or integrally formed with the platform 52. The cutout 55 allows a distal end 60b of the elastic finger 60 to move (i.e., rotate) about the proximal end 60a.In the illustrated example, the elastic finger 60 is generally coplanar to a plane formed by the top 52a of the platform 52, but in other examples any arbitrary relative angle can be formed between a plane formed by the elastic finger 60 and the plane formed by the top 52a of the platform 52.

[0023] A projection 62 is positioned at the distal end 60b of the elastic finger 60. This projection 62 is generally a conical or frustoconical element having an angled side wall 64 extending away from the top 52a of the platform 52 (i.e., in the same upward direction as the wall 54). Other shapes or arrangements of the projection 62 are possible, such as spherical, pyramidal, etc. The projection 62 may additionally include a through-hole 66.

[0024] In general, the elastic finger 60 is configured such that, when coupled to the frame 50, it exerts an upward pressure force on the reader 11 and holds the reader 11 in place. As in Fig. As shown in Figure 7, to attach the reader 11 to the frame 50, the base 12 is moved from the rear 52d of the platform 52 towards the front 52c of the platform 52. This relative movement causes the lower section 12b of the base 12 to contact the projection 62, thereby pressing the elastic finger 60 downwards. The continued pressure of the reader 11 into the frame 50 causes the projection 62 to align with the connecting opening 16 of the base 12. Since the lower section 12b of the base 12 is no longer engaged with the projection 62, the distal end 60b of the elastic finger 60 moves upwards, so that the projection 62 is at least partially inserted into the connecting opening 16. In this position, the angled side wall 64 can rest against an edge or contact surface 16a of the connecting opening 16, and thus the elastic finger 60 can exert an upward pressure force on the base 12.

[0025] Since the wall 54 is concave and the curved base surface 14 is convex, the curved base surface 14 is nested within the wall 54 when the reader 11 is coupled to the frame 50. It is understood that the nesting of the reader 11 within the frame 50 allows unimpeded or limited rotation about an axis “L” extending from the projection 62 of both components, relative to each other. In some examples, the curved base surface 14 and the wall 54 may be positioned such that, up to and including a gap or clearance of approximately 5 mm, the curved base surface 14 does not frictionally engage with the wall 54. In other examples, however, the curved base surface 14 may contact the wall 54 in a manner that results in frictional engagement between the two surfaces. In any case, the wall 54, by coupling the reader 11 to the frame 50, contributes to limiting the relative non-rotational movement of the reader 11 relative to the frame 50.

[0026] The elastic element 60 generates a force that resists the pushing or removal of the reader 11 by a user until the pushing force is greater than the locking force between the angled side wall 64 and the contact surface 16a. The force required to remove the reader 11 from the frame 50 can be varied by adjusting the angle α ( Fig.4) the angle of the angled side wall 64 relative to the axis L. If the angle α is relatively small (e.g., between approximately 91° and 135°, resulting in a relatively slight inclination), the engagement force between the angled side wall 64 and the contact surface 16a is low, and the reader 11 can therefore be removed from the frame 50 with minimal effort. Conversely, with a relatively large angle α (e.g., between approximately 135° and approximately 175°, resulting in a relatively steep inclination), the engagement force between the angled side wall 64 and the contact surface 16a is high, so a greater force is required to remove the reader 11 from the frame 50.

[0027] To operate and / or reposition the reader 11, a user can grasp a section of the reader housing 30 and push a section (e.g., the upper section 32a) of the housing body 32 in a desired direction to tilt the reader housing 30 up or down relative to the base 12 and the stand 50. The user can also rotate the reader 11 about the axis L relative to the stand 50. Configured in this way, the user can position a barcode or other object within the field of view (FOV) of the reader 11. The user can then activate a trigger or other mechanism that causes the reader 11 to capture an image of the barcode or other object. In some examples, the reader 11 can also be activated in a presentation mode to capture an image of the barcode or other object.

[0028] In each of these configurations of the angled side wall 64, an additional release mechanism 68 can be provided to facilitate the removal of the reader 11 from the frame 50. The release mechanism 68 can, for example, be in the form of a contact area on the elastic finger 60, which a user can press down to lower the projection 62 and decouple it from the connecting opening 16. In these examples, the user can use a tool (not shown) to press the elastic finger 60. In other cases, the platform 52 can project rearward beyond the base surface 12, so that the rear portion of the platform remains accessible to the user when the reader 11 is mounted in the frame 50, allowing the user to press down the contact area 68, for example, with a finger.

[0029] In other examples, the release mechanism 68 may be in the form of a rod that is inserted into the through-hole 66 of the elastic finger 60, which extends through and under a lower surface of the frame, desk, table, and / or display to which the assembly 10 is mounted. In these examples, a user can grasp the rod under the underside of the frame and pull downwards to lower the elastic finger 60 and thus release the projection 62 from the connecting opening 16. Other examples are possible.

[0030] In some aspects, the barcode reader assembly 10 can include any number of optional arrangements, configurations, and / or components. For example, in some approaches, the projection 62 or the contact surface 16a of the connecting opening 16 can support any number of detents that engage in a ratchet mechanism or a projection supported by the contact surface 16a or the projection 62, which selectively engages the detents, thereby positioning and holding the reader 10. A relative rotation between these detents and the corresponding projection causes the projection to move into an adjacent detent and be held there until a pushing force applied by the user is greater than the engagement force between the detent and the projection.As a result, the reader 11 can be selectively held at a desired angle or configuration relative to the frame 50.

[0031] In some aspects, the connecting opening 16 can have the form of a conical (or arbitrarily shaped) cavity corresponding to the shape of the projection 62. In such an arrangement, the angled side wall 64 engages forcefully with the side wall of the cavity, which may include recesses to limit the relative movement between the frame 50 and the reader 11 to a desired number of intervals. Other examples are possible.

[0032] In some approaches, the reader 11 can be selectively and rotationally locked relative to the frame 50. In these examples, the wall 54 can include a notched section (not shown) extending along its length at any desired location (e.g., in the middle of the wall 54 at or near the front 52c of the platform 52). This notched section can be dimensioned to accommodate the data and / or power cable 36. For example, a user can tilt the reader housing 30 downward so that the rear section 32d of the housing body 32, and thus the data and / or power cable 36, is positioned above the top of the wall 54. The user can then rotate the reader 11 about the axis L relative to the frame 50 until the data and / or power cable 36 is positioned above the notched section.The user can then tilt the reader housing 30 back into a horizontal position so that the data and / or power cable 36 is inserted into the notched section, thus restricting the relative rotation between the reader 11 and the frame 50. The user can reverse these steps to allow relative rotation between these components again. Other examples of locking mechanisms are possible.

[0033] In some examples, the arrangement of the components of the barcode reader assembly 10 can be reversed. For example, the elastic finger 60 can be supported by the base 12 and have a projection that extends downwards into a connecting opening and / or a cavity formed by the frame 50.

[0034] In this configuration, the barcode reader assembly 10 can use a single accessory frame capable of selectively rotating and locking the reader 11. Due to the arrangement of the wall 54 and the elastic finger 60, the reader 11 can be rotated in both the locked and unlocked configurations. Therefore, a robust rotation mechanism can be used while maintaining minimal gaps or clearances between components and surfaces moving relative to each other (i.e., the curved base surface 14 of the base 12 and the wall 54 of the frame 50). Consequently, the moving components are not exposed to any elements that could impede the proper tilting or rotation of the device, and the likelihood of user finger entrapment is reduced.

[0035] In one or all of these implementations, the barcode reader assembly 10 can be operated alternately in at least one manual mode or a presentation or handheld mode. The assembly 10 can be lifted as a single unit from the support surface and held in the hand of an operator. In a handheld or manual operating mode, a trigger mechanism is manually actuated and pressed to initiate the reading of a symbol / document, such as a barcode on a product, within a range of working distances relative to a window. In a presentation or handheld operating mode, the reader 10 is mounted on the support surface, where symbol / document targets are presented for reading within a range of working distances relative to a window.
