The deformable arm includes a first end configured to be biased to a first position to engage a latch of a door of the box to prevent the latch from opening; and a receiving surface configured to receive an external force to move the deformable arm to a second position that disengages the first end from the latch, thereby enabling the latch to open when the external force is applied to the receiving surface.

Description

Technical Field

[0001] The present disclosure relates to mechanisms for securing cabinet doors, and more particularly, to double-action mechanisms for cabinet doors including a locking mechanism for a latch of the door. Background Art

[0002] Battery-powered electronic devices are used in a wide variety of applications. Examples of common battery types used in electronic devices include, but are not limited to, 6-volt and 9-volt batteries having a rectangular prismatic form factor, cylindrical C, D, AA, and AAA battery cells, and various types of round button cells. Some devices employ battery packs that integrate two or more battery cells into a single power supply. More generally, the term "battery" refers to one or more battery cells that store electrical energy used by an electronic device in operation. An electronic device includes a battery case that physically holds the battery and provides electrical connections for the battery to power the electronic device.

[0003] Many electronic devices allow access to a battery compartment to enable replacement of the batteries via a door that secures the battery compartment when in a closed state and allows access to the battery compartment when in an open state. In some battery compartment configurations, the door also engages the batteries using a physical connection, an electrical connection, or both a physical connection and an electrical connection when in a closed state, while in other configurations, the door merely controls access to the battery compartment.

[0004] Existing battery compartment doors allow users to access the battery compartment to replace batteries, but in some cases, unauthorized users (such as children) may also be able to open the door to access the battery compartment. Children who access the batteries in the compartment while unsupervised may be injured after removing the batteries from the compartment. Of course, various locking mechanisms (including key locks and doors secured by screws) are known in the art and are generally effective in preventing unauthorized access. However, these mechanisms may also make it difficult for authorized users to access the battery compartment for legitimate purposes, such as replacing batteries after the existing batteries are discharged. In some cases, such as medical monitoring equipment, authorized users may need to replace batteries with minimal difficulty, while the equipment should still prevent unauthorized access to the battery compartment. Therefore, improvements to the locking mechanisms of compartment doors (including battery compartment doors) that reduce or eliminate these problems would be beneficial. Summary of the invention

[0005] In one embodiment, a locking mechanism for a box has been developed. The locking mechanism includes a deformable arm fixed to a housing of the box and positioned within the box. The deformable arm includes: a first end configured to be biased to a first position to engage a latch of a door of the box to prevent the latch from opening; and a receiving surface configured to receive an external force to move the deformable arm to a second position that disengages the first end from the latch, thereby enabling the latch to open when the external force is applied to the receiving surface.

[0006] In another embodiment, a case having a locking mechanism includes a shell that forms the case, an opening in the shell that allows access to the case, and a door that is configured to engage the opening in the shell to prevent access to the case when in a closed state and to allow access to the case when in an open state. The door further includes a latch that includes a latch member that is configured to move between a latched position that allows the door to engage with the shell and remain closed and an unlocked position that allows the door to be opened, and a deformable arm that is fixed to the shell of the case and positioned within the case. The deformable arm includes: a first end portion, the first end portion is configured to be biased to a first position to engage the lock catch, thereby preventing the lock catch from moving from the locked position to the unlocked position; and a receiving surface, the receiving surface is configured to receive an external force to move the deformable arm to a second position in which the first end portion is disengaged from the lock catch, thereby enabling the lock catch to be moved to the unlocked position when the external force is applied to the receiving surface.

[0016] For the purpose of promoting an understanding of the principles of the embodiments described herein, reference is now made to the drawings and descriptions in the following written specification. The references are not intended to limit the scope of the subject matter. This patent also includes any changes and modifications to the illustrated embodiments, and includes further applications of the principles of the described embodiments as would normally occur to a person skilled in the art to which this document belongs.

[0017] FIG. 1 depicts an electronic device 100 having a housing 150 that forms a case 104 having an opening that receives a door 132 and includes a locking mechanism 108. The locking mechanism 108 includes a deformable arm 112 that engages a latch 136 formed in the door 132. In view 160, the door 132 is closed to prevent access to the case 104, while in view 170, the door is open to enable access to the case. Although FIG. 1 depicts the door 132 as being completely removable from the housing 150 of the case 104, in alternative embodiments, the open door remains attached to the case using a hinge or other attachment structure, and the locking mechanism 108 can be used with both removable and non-removable doors. As described in further detail below, the deformable arm 112 is biased to a first position so that a first end 114 of the deformable arm 112 can engage the latch 136 in a locked configuration. The external force applied to the deformable arm 112 moves the deformable arm 112 to a second unlocked position in which the first end 114 of the deformable arm is not engaged with the latch 136, which then enables the latch 136 to open when the deformable arm 112 is placed in the second position.

[0018] For purposes of illustration, electronic device 100 is an electronic blood glucose meter (BGM) device, and case 104 is a battery case that includes receptacles 106A and 106B for two button batteries for powering the operation of the device. However, the embodiments described herein may be used with many other electronic devices that utilize battery cases, including battery cases that receive different types and numbers of battery cells or battery packs. Furthermore, while the embodiments described herein describe battery cases, the dual-action door mechanisms with locking mechanisms described herein may also be used to secure cases that house items other than batteries.

[0019] View 160 of FIG. 1 depicts the door 132 in a closed and locked configuration that prevents access to the enclosure 104. In addition to the latch 136, the door 132 also includes an opening 140 that allows access to a receiving surface 124 formed on the deformable arm 112 of the locking mechanism 108. As depicted in both views 160 and 170 of FIG. 1 , the receiving surface 124 is a button (also referred to as a "pin") extending from the deformable arm 112. In the embodiment of FIG. 1 , the receiving surface button 124 is formed flush with the opening 140 in the door 132, but in other embodiments, the receiving surface is recessed below the opening 140, or the button 124 or receiving surface structure extends through the opening 140. In alternative embodiments, the receiving surface is a flat portion of the deformable arm 112 or a structure having a different shape and size that enables an external force to move the deformable arm from a first position to a second position to unlock the latch 136. Embodiments that place the receiving surface flush with or below the opening 140 reduce or eliminate the ability of a user to manually unlock the latch 136 without using a pen or other implement to engage the deformable arm 112 through the opening 140, which helps prevent unauthorized access by children. Additionally, while the embodiments described herein include an opening 140 formed in the door 132, in alternative embodiments, the opening may be formed in at least one of the housing or the door that forms the enclosure.

[0020] During operation, an external force pushes the receiving surface of the button 124, as indicated by arrow 134. In the exemplary embodiment of FIG. 1, the user applies an external force using, for example, an implement such as the tip of a ballpoint pen, tweezers, or other similar objects to push the button 124 and move the deformable arm 112 to the second position disengaged from the catch 136. The implement is not necessarily a specific tool (such as a specific type of screwdriver) and can be an object that is easily accessible to the user. In addition, in some embodiments, the button 124 is configured to enable manual operation (i.e., operation with one or more fingers) without the use of an implement.

[0021] The external force that moves the deformable arm 112 to the second position enables the user to operate the lock 136 by applying a separate force as shown by arrow 138, while maintaining the deformable arm 112 in the unlocked position by applying an external force in direction 134. The door 132 is unlocked and removed from the housing 150 to enable access to the cabinet 104. Therefore, FIG. 1 and other embodiments described herein depict a "double-action door mechanism" because the process of opening the cabinet door includes: a first action to unlock the locking mechanism; and a second action to unlock the lock while the locking mechanism remains in the unlocked configuration.

[0022] View 170 of FIG. 1 depicts the case 104 in an open configuration with the door 132 removed. In view 170, when no external force is applied to the receiving surface button 124, the deformable arm 112 of the locking mechanism 108 biases the first end 114 of the deformable arm 112, which includes the first protrusion 116A and the second protrusion 116B, to a first position. The second end 128 of the deformable arm 112 is fixed to the housing 150 forming the case 104. In the embodiments described herein, the deformable arm 112 is an integral member formed as a molded portion of the housing 150, while in other embodiments, the deformable arm 112 is a separate structure that is fixed to the housing via welding, riveting, friction fit connection, or any other suitable attachment structure. The deformable arm 112 is a spring. More specifically, the deformable arm 112 forms a cantilever spring, wherein the first end 114 having the protrusions 116A and 116B is a free end, and the second end 128 forms a fixed end. In the embodiment described herein, the second end 128 also forms a fulcrum of the cantilever spring, but alternative embodiments may employ a fulcrum separate from the attachment location of the second end 128 of the deformable arm 112.

[0023] As depicted in view 170 of FIG. 1 , the first end 114 of the deformable arm 112 includes projections 116A and 116B configured to engage first and second barbs, respectively, formed in the latch 136. When the deformable arm 112 is in the first position, the projections 116A and 116B engage the barbs to lock the latch 136 and prevent the latch 136 from being opened. The barbs are described in more detail below. The first projection 116A is offset from the second projection 116B to form a gap 120 that enables a deformable member in the latch 136 to be positioned between the first projection 116A and the second projection 116B so that the latch 136 can be opened when the projections 116A and 116B are disengaged from the barbs when the deformable arm 112 is moved to the second position. Alternative embodiments of the deformable arm 112 may include one or more projections or other members that engage with the latch.

[0024] FIG. 2 depicts an interior view of the housing 104 when the door 132 is closed and the deformable arm 112 of the locking mechanism 108 is in a first position to prevent the latch 136 from being opened. FIG. 2 depicts additional elements of the latch 136 including a barb 234 and a U-shaped deformable member 236. One end of the U-shaped deformable member 236 is fixed to the door 132 and the other end is a free end that engages the housing 150 when the door 132 is closed. The barb 234 extends laterally from the deformable member 236 in the latch 136 and engages a protrusion 116B from the deformable arm 112 of the locking mechanism 108. FIG. 2 is a cross-sectional view depicting only one barb 234 and one protrusion 116B, but in at least one embodiment, a second barb on the latch 136 engages another protrusion 116A. The U-shaped deformable member 236 is a spring that biases the latch 136 into engagement with the housing 150 to secure the door 132 to the housing 150 when the door 132 is closed. The U-shaped deformable member 236 is positioned in the gap 120 of the deformable arm 112 depicted above in FIG. 1 , and when the locking mechanism 108 is unlocked, a user applies an external force to the U-shaped member to move the latch 136 from the closed position depicted in FIG. 2 to a second position, allowing the door 132 to be opened while the U-shaped deformable member 236 remains in the gap 120 of the deformable arm 112.

[0025] When the deformable arm 112 is in the first position depicted in FIG. 2 , the barbs (including the barb 234) engage the protrusions 116A and 116B of the deformable arm 112, and an external force applied to the latch 136 in the direction 208 does not move the latch 136 or only moves the latch 136 a short distance (e.g., less than 1 mm) that is insufficient to open the door 132. In one embodiment, the barb 234 and the deformable arm 112 are formed of a material such as a thermoplastic, and its shape and thickness provide resistance to prevent the latch from opening in response to a force of at least 30 Newtons in the direction 208 to prevent the latch 136 from opening without damaging any components in the device 100. Other embodiments may provide lesser or greater amounts of resistance based on the materials, size, and shape of the buckle and locking mechanism components, including as practical examples minimum resistance levels in the range of 30 to 100 Newtons, although 100 Newtons is not a strict upper limit on the forces that embodiments of the buckle and locking mechanism can withstand.

[0026] As depicted in FIG. 2 , an external force applied to the receiving surface of the button 124 as indicated by arrow 204 pushes the deformable arm 112 downward from the first position of FIG. 2 to a second position in the housing 104 . In one embodiment, the first end 114 of the deformable arm 112 has a range of motion of approximately 2 mm between the first position and the second position, although other embodiments may have a greater or lesser range of motion. In the second position, the protrusions 116A and 116B no longer engage the barbs, including the barbs 234, on the latch 136 that unlock the latch. In the example of FIG. 2 , the deformable arm 112 moves downward into the housing 104 to the second position, but in other embodiments, the direction of movement of the deformable arm 112 may be different (e.g., upward, lateral, or diagonal). In one embodiment, a force of 1 Newton or greater moves the deformable arm 112 to the second position, although other embodiments move in response to greater or lesser amounts of force based on the stiffness of the deformable arm structure. 2 , once the lock 136 is unlocked, a second force applied to the lock 136 as indicated by arrow 208 pushes the deformable member 236 in direction 208 to disengage the lock 136 from the housing 150, allowing the user to open the door 132. To open the door 132, the user maintains the first force to disengage the deformable arm 112 from the lock 136 while applying the second force to unlock the lock 136. If the user stops applying force to the receiving surface button 124 without opening the door 132, the spring bias of the deformable arm 112 returns the first end portion to the first position depicted in FIG. 2 to lock the lock 136.

[0027] FIG3 depicts additional details of an embodiment of the lock 136. In FIG3, view 350 depicts the lock 136 engaged with the barb 234B, which engages the protrusion 116B of the deformable arm 112. In the embodiment of FIG3, the barb 234B is formed with a rear surface having a sufficient size to fully engage the protrusion 116B in the first end of the deformable arm 112. View 360 is a simplified plan view of a portion of the lock 136, which depicts two laterally extending barbs 234A and 234B. As described above, when the locking mechanism 108 locks the lock 136, the barbs 234A and 234B engage the protrusions 116A and 116B in the deformable arm 112, respectively, and the deformable member 236 in the lock 136 is positioned in the gap 120 between the protrusions 116A and 116B.

[0028] In addition to unlocking the locking mechanism and opening the door in the electronic device 100 using a double-action door mechanism, the embodiments described herein can also close the open door using only a single-action operation instead of a double-action operation for opening the door. FIG. 4 depicts the operation of closing the door in more detail. In view 450, the door 132 is in the process of closing when the latch 136 begins to engage the housing 150. When the latch 136 engages the housing 150, the barb 234B engages the protrusion 116B in the first end of the deformable arm 112 as shown by arrow 404, and the barb 234B pushes the deformable arm 112 downward as shown by arrow 408. Although not explicitly shown in FIG. 4, the barb 234A also pushes the protrusion 116A of the deformable arm 112 in a similar manner. Thus, when the door 132 is closed, the latch 136 moves the deformable arm 112, and the user need not apply a separate external force to the deformable arm 112 beyond the force used to engage the latch 136 with the housing 150 when closing the door 132. As depicted in view 460, once the latch 136 has engaged the housing 150 to close the door 132, the barb 234B (and similar barb 234A) no longer engages the protrusions 116A and 116B of the deformable arm 112, and the deformable arm 112 returns to the first position to lock the latch 136 in place, as indicated by arrow 412.

[0029] FIG5 depicts additional details of an embodiment of a deformable arm 112 in a locking mechanism 108 that is molded from a thermoplastic integral with all or a portion of a housing 150. In FIG5, view 550 depicts the deformable arm 112 of the locking mechanism 108 from a battery compartment 104, and view 560 depicts the same element from the opposite side in a separate electronics compartment 504 formed in the housing 150. In the battery compartment 104, the deformable arm 112 is secured to the remainder of the housing at a second end 128 that forms an attachment point and a fulcrum, enabling the deformable arm 112 to be a cantilever spring with the first end 114 being a free end. In the embodiment of FIG5, the housing 150 and the deformable arm 112 are both formed from a thermoplastic, such as a thermoplastic compound sold commercially under the name Lexan, or another suitable polymer composition. During the forming process, molten thermoplastic flows through the mold and forms the deformable arm 112 starting from the second end 112 and extending to the first end 114 and the protrusions 116A and 116B.

[0030] 6 and 7 depict finite element analysis (FEA) results of different sections of the deformable arm 112 during operation. View 604 of FIG6 depicts stresses experienced at the second end 128 of the deformable arm 112 when an external force is applied to the receiving surface 124 to move the deformable arm 112 from a first position to a second position. View 608 of FIG6 depicts that the first end 114 of the deformable arm undergoes a displacement sufficient to move the first end 114 of the deformable arm 112 from the first position to the second position in response to an external force of 1 Newton, and more generally in response to a force in the range of greater than 0 Newtons to 10 Newtons. View 704 of FIG. 7 depicts the stress experienced by the deformable arm 112 when the locking mechanism 108 is locked and an external force is applied to attempt to open the lock, and as long as the external force is below a maximum load level (e.g., in the range of 30 Newtons to 100 Newtons, or other set maximum force level), the deformable arm 112 will resist opening the lock. View 708 depicts the displacement of the first end 114 of the deformable arm 112 when a force (as shown by arrows 712) from the lock 136 is applied to the protrusions 116A and 116B.

[0031] FIG8 depicts an electronic device 100 having another embodiment of a door 832. The door 832 includes the same latch 136 as included in the door 132 described above, and further includes a recess 808 formed around the opening 140. Although FIG8 depicts the recess 808 formed around the opening 140 in the door 832, in another embodiment including an opening formed in the housing of the case, the recess may be formed in the housing or in both the housing and the door. The recess 808 enables the receiving surface button 124 of the deformable arm 112 to extend through and over the opening 140, which simplifies manual operation of the button 124 by the user because the recess 808 provides sufficient clearance for the user to push down the button 124 with a finger. In contrast, in the above-described embodiment—where the door 132 does not include a recess and where the receiving surface of the button 124 does not extend through the opening 140—manual operation without an implement is generally impractical. The recess 808 also allows manual access to the receiving surface button 124 while the upper end of the receiving surface button 124 remains at or below the surface level of the remainder of the door 832 located outside the recess 808, which protects the button 124 from damage or being caught in the user's pocket or other belongings.

[0032] FIG9 depicts an embodiment of a door 132 that includes indicia formed on a surface of the door 132 to assist a user in operating the locking mechanism 108 to unlock the striker 136. In FIG9, an icon 904 indicates an unlocking operation, and a guide symbol 906 surrounds the opening 140 in the door 132 and a receiving surface of the button 124 that receives an external force from a user to unlock the striker 136. As described above, the embodiments herein enable a user to unlock the striker 136 manually or using a simple implement (such as the end of a ballpoint pen or other object) in the embodiment of the door 832 of FIG8 without requiring specialized tools, such as a specific type of screwdriver in the embodiment of the door 132 of FIG9 and other figures. In addition, the double-action door mechanism including the locking mechanism 108 and the striker 136 reduces or prevents unauthorized users (such as children) from accessing the battery box 104 because these users are generally unable to simultaneously perform the unlocking and unlocking actions of the double-action door mechanism. Additionally, as described above, closing the door after it has been opened does not require any additional action other than latching the door in the opening of the box.

[0033] Although the embodiments described herein depict a battery box for purposes of illustration, the locking mechanisms described herein may also be used with dual-action door mechanisms for other types of boxes. A non-limiting example of another type of box is a box that holds medications for a patient. The medication box may be part of an electronic or non-electronic medication container device, and the embodiments described herein may prevent unauthorized access to medications in the box in the same manner as described above for preventing unauthorized access to batteries in a battery box.

[0034] It should be understood that variations of the above-described embodiments and other features and functions or their alternatives may be desirably combined into many other different systems, devices, applications or methods. Those skilled in the art may subsequently make various currently unforeseen or unanticipated substitutions, modifications, changes or improvements, which are also intended to be covered by the following claims.
