This disclosure generally relates to securing outdoor vending machines. In particular, the disclosure relates to protecting money cassettes within an automated teller machine (ATM).
Automated Teller Machines (ATMs) provide an automated user experience to withdraw funds from a user's bank account. Customers have come to appreciate the accessibility and availability of the ATM. For example, ATMs can provide customers access to money within a checking account after-hours, late at night when the bank is closed. The accessibility to the customer's checking account has automated several aspects of the banking relationship and provides customers with an alternative means to access funds after hours or without transacting with a human banker.
However, this ease of access comes at a price. Organized criminals and N others have begun stealing ATMs and/or breaking into ATMs to expose money cassettes housed therein. A structural method of securing the ATM is needed that prevents criminal activity without impinging on the accessibility of legitimate banking customers.
The subject matter of the present application has been developed in response to the present state of the art, particularly in response to the shortcomings of securing outdoor Automated Teller Machines (ATMs) that currently available techniques have not fully solved. Accordingly, the subject matter of the present application has been developed to provide a gate and/or frame to lock the ATM and overcome at least some of the above-discussed shortcomings of prior art techniques.
The following is a non-exhaustive list of examples, which may or may not be claimed, of the subject matter, disclosed herein.
In one embodiment, an apparatus comprising an arm, a lockpin, and a lock is described. The arm includes an attachment. The lockpin engages the attachment in an engaged position and the lock locks an abutment that provides access to release the lockpin from the engaged position. In response to applying a force to rotate the arm in the engaged position, the lockpin restrains the arm, and the force is not distributed to the lock. The preceding subject matter of this paragraph characterizes example 1 of the present disclosure.
The arm may include a rotatable rod that extends axially through the arm. The rotatable rod may be free to rotate within the arm and/or housed within the arm. The preceding subject matter of this paragraph characterizes example 2 of the present disclosure, wherein example 2 also includes the subject matter according to example 1 above.
The arm may include a reinforced steel wall that is at least 0.5 inches thick. The preceding subject matter of this paragraph characterizes example 3 of the present disclosure, wherein example 3 also includes the subject matter according to example 1 above.
In various embodiments, a heat sensor, a vibration sensor, and/or a contact switch may send an alarm signal to activate/trigger an alarm when heated, jarred, or when the arm and the abutment are not in contact. In one embodiment, the contact switch determines a pressure between the attachment of the arm and the receiver of the abutment and sends the alarm signal to activate/trigger an alarm when the lock has not received a key and the pressure is below a threshold. The preceding subject matter of this paragraph characterizes examples 4-7 of the present disclosure, wherein examples 4-7 also includes the subject matter according to example 1 above.
In various embodiments, the lockpin includes multiple points of contact with the attachment. For example, the lockpin may bear against the attachment in double shear. The preceding subject matter of this paragraph characterizes examples 8-9 of the present disclosure, wherein examples 8-9 also includes the subject matter according to example 1 above.
In another embodiment, an apparatus includes an arm, a lockpin, and a lock. The arm includes an attachment configured to lock the arm to prevent rotation of the arm. The lockpin engages the attachment of the arm in an engaged position and the lock couples to the lockpin to prevent releasing the lockpin from the engaged position. In response to a force to rotate the arm in the engaged position, the lock is not engaged. The preceding subject matter of this paragraph characterizes example 10 of the present disclosure.
The lockpin may include a double-shear lockpin. The preceding subject matter of this paragraph characterizes example 11 of the present disclosure, wherein example 11 also includes the subject matter according to example 10 above.
The the lockpin may include a tongue. The tongue extends from the lockpin and the lock engages the tongue in a locked position to prevent removal of the lockpin. When the lockpin is in the engaged position, the force to rotate the arm bears on the lockpin and fails to bear against the lock. The preceding subject matter of this paragraph characterizes example 12 of the present disclosure, wherein example 12 also includes the subject matter according to example 10 above.
In various embodiments, the apparatus includes a frame. The frame may include a first stile at a first front end, a second stile at a second front end opposite the first front end, and a rail extending between the first stile and the second stile. A cover may extend between the first stile and the second stile and at least partially surround the arm and the attachment when coupled to the abutment. The preceding subject matter of this paragraph characterizes example 13 of the present disclosure, wherein example 13 also includes the subject matter according to example 10 above.
In some embodiments the frame includes a base plate, a third stile, a fourth stile, and a rear rail. The third stile is located at a third rear end and coupled to a rear of the base plate at the third rear end opposite the first stile at the first end. The fourth stile is located at a fourth rear end and coupled to the rear of the base plate at the fourth end opposite the second stile at the second end. The rear rail extends between the third stile and the fourth stile opposite the rail extending between the first stile and the second stile, such that the frame surrounds a structure. The preceding subject matter of this paragraph characterizes example 14 of the present disclosure, wherein example 14 also includes the subject matter according to example 13 above.
The frame may include a left panel coupled to and extending between the first stile and the third stile, a right panel coupled to and extending between the second stile and the fourth stile, and a back panel coupled to and extending between the third stile and the fourth stile. A cap may be coupled to the rail and the rear rail and extend between the cover, the back panel, the left panel, and the right panel. The first stile, the second stile, the third stile, and the fourth stile may be coupled to the base plate. The rail may be coupled to the first stile and the second stile and the rear rail may be coupled to the rear third stile and the rear fourth stile. The preceding subject matter of this paragraph characterizes example 15 of the present disclosure, wherein example 15 also includes the subject matter according to example 14 above.
In some embodiments, the first stile, the second stile, the third stile, and the fourth stile may be fabricated from and/or comprise reinforced steel and the frame may be disposed around the structure with a predetermined clearance between the frame and the structure. The preceding subject matter of this paragraph characterizes example 16 of the present disclosure, wherein example 16 also includes the subject matter according to example 14 above.
In another embodiment, an Automated Teller Machine (ATM) is described including a frame, a gate, and a cover. The frame includes a base plate, a first stile coupled to the base plate at a first end, a second stile coupled to the base plate at a second end, and a rail extending over the base plate between the first stile and the second stile. The gate includes an arm with a pivot and an attachment. The attachment is configured to lock the arm to prevent rotation of the arm. The gate includes an abutment with a lockpin and a lock. The lockpin is configured to engage the attachment of the arm in an engaged position to prevent the arm from pivoting. The lock is couple to the abutment to prevent access to the lockpin in the abutment. In response to an applied force to rotate the arm when the lockpin is in the engaged position, the lock is not engaged. The preceding subject matter of this paragraph characterizes example 17 of the present disclosure.
The cover may completely enclose the abutment and the attachment of the arm. The preceding subject matter of this paragraph characterizes example 18 of the present disclosure, wherein example 18 also includes the subject matter according to example 17 above.
The base plate, the first stile, the second stile, and the rail may include reinforced steel. The first stile and the second stile may be coupled to the base plate, and the lock rail may be coupled to and/or extend between the first stile and the second stile. The preceding subject matter of this paragraph characterizes example 19 of the present disclosure, wherein example 19 also includes the subject matter according to example 17 above.
The frame may be located within a predetermined distance of the ATM. The frame may prevent wrapping a chain around the ATM without also encircling the frame. The preceding subject matter of this paragraph characterizes example 20 of the present disclosure, wherein example 20 also includes the subject matter according to example 17 above.
The described features, structures, advantages, and/or characteristics of the subject matter of the present disclosure may be combined in any suitable manner in one or more examples and/or implementations. In the following description, numerous specific details are provided to impart a thorough understanding of examples of the subject matter of the present disclosure. One skilled in the relevant art will recognize that the subject matter of the present disclosure may be practiced without one or more of the specific features, details, components, materials, and/or methods of a particular example or implementation. In other instances, additional features and advantages may be recognized in certain examples and/or implementations that may not be present in all examples or implementations. Further, in some instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the subject matter of the present disclosure. The features and advantages of the subject matter of the present disclosure will become more fully apparent from the following description and appended claims, or may be learned by the practice of the subject matter as set forth hereinafter.
In order that the advantages of the subject matter may be more readily understood, a more particular description of the subject matter briefly described above will be rendered by reference to specific examples that are illustrated in the appended drawings. Understanding that these drawings, which are not necessarily drawn to scale, depict only certain examples of the subject matter and are not, therefore, to be considered to be limiting of its scope, the subject matter will be described and explained with additional specificity and detail through the use of the drawings, in which:
Banks and their customers have adopted Automated Teller Machines (ATMs) for their accessibility, availability, and ease of use. However, crooks and thieves have noticed that ATMs are often left vulnerable and attack ATMs to break into the money cassettes included in each ATM. In general, a gate can be used in front of the ATM to make it more difficult for a would-be thief to break open the ATM. The gate secures the money cassettes within the ATM from being removed (e.g., by removing a front panel of the ATM). In addition, frames can be added to the gate to surround the ATM and prevent the removal of the ATM. For example, the frame prevents wrapping a chain around an unsecured ATM and is known as, a “chain attack.”
The gate and/or frame is/are capable of being designed to withstand increased forces than a stand-alone ATM. The gate and/frame approach described herein permits banks and others to customize the security of the ATM. For example, an ATM housed partially within a brick building may use components of the gate and/or the front parts of a frame but may not need the rear frame. Similarly, a wholly exposed ATM may include a gate and front and rear portions of the frame to surround and secure the ATM completely. The gate and frame can be constructed to obscure the would-be criminal the locking mechanisms and may further be designed with fail-safes that make an attack fail by designing fail locations other than those the thief is most likely to attack. For example, in various embodiments disclosed herein, the lock protects a lockpin that needs to be removed to gain access to the interior of the ATM. However, the lock may not be subject to any force(s) (e.g., bending, bearing, and/or shear) when the ATM is attacked. The embodiments disclosed herein provide configurations that enable and/or allow a more robust and secure design of the frame and/or gate protecting an ATM.
The arm 108 pivots or rotates about the pivot 110 that secures the arm 108 on the first end 112 and locks at an abutment 122 at the second end 118 of the gate 100. The attachment 116 couples to form the abutment 122 on the post 114. The abutment 122 includes a lockpin 124 that engages the attachment 116 in an engaged position 126 to prevent the arm 108 from pivoting. The lockpin 124 engages the attachment 116 of the arm 108 in an engaged position 126 (see,
The abutment 122 can include the lockpin 124 to lock the arm 108 relative to the post 114 and/or a puck lock (e.g., lock 128) secured to a secondary structure 130 of the abutment 122. The secondary structure 130 includes a structure that couples directly to the lock to prevent access to the lockpin 124. The secondary structure 130 of the abutment 122 can be a separate box-cover 132, as shown in
In other words, the lock 128 inhibits and/or prevents access to the lockpin 124 without a key 134. The lock 128 secures and locks the secondary structure 130 of the abutment 122 that provides user access to the lockpin 124. The lock 128 is coupled to the secondary structure 130 to inhibit the release of the lockpin 124 from the engaged position 126. The lockpin 124 secures the abutment 122 to the attachment 116 of the arm 108 to lock the gate 100 and prevent rotation at the pivot 110. For example, the lockpin 124 may experience a shear or bearing load between the abutment 122 and the attachment 116 of the arm 108 to lock the gate 100.
In response to an applied rotational force that attempts to rotate the arm 108 when the lockpin 124 is in the engaged position 126, the lockpin 124 restrains the arm 108 and distributes the force from the arm 108 to the hinge column 106 and/or the support post 114. In some embodiments, the lockpin 124 may include multiple points of contact (e.g., contact surface 136) with the attachment 116. For example, the lockpin 124 may bear against the arm 108 in double shear, as shown in
When the lockpin 124 is in the engaged position 126 it secures the attachment 116 of the arm 108 to the support 138 of the post 114. In the engaged position 126 the arm 108 is locked relative to the hinge column 106 and support post 114. The pivot 110 at the first end 112 is not free to rotate, since the lockpin 124 is securing the attachment 116 of the arm 108 at the second end 118. Similarly, the lockpin 124 prevents rotation of the arm 108 at the second end 118 by securing and/or fastening the arm 108 to the support 138 of the post 114. The lock 128 functions to secure the box-cover 132 to the support 138 and inhibit or prevent unauthorized access to the lockpin 124 (e.g., without unlocking the lock 128). In other words, when the lockpin 124 is in the engaged position 126, a rotational force on the arm 108 (e.g., to open the gate 100) applies a reaction force (e.g., shear, bending, and/or bearing) on the lockpin 124 but does not force or bear on the lock 128. The lockpin 124 is in the load path but the lock 128 is not.
The lockpin 124 enhances the structural force that can secure the arm 108 relative to the hinge column 106 and/or support post 114. The locking mechanism of the lockpin 124 can provide a more robust design, materials, and/or contact area/surface 136 for the bearing area of the joint. For example, the lockpin 124 may include an increased number of contact surfaces 136 and/or increase the bearing area from the single shear joint of the lock 128 configuration to the double shear joint configuration shown in
The lock 128 in
Bolt covers 142 may also capture and at least partially surround any bolts or fasteners 120 that secure the hinge column 106 and support post 114 to the ground. The post 114 may include multiple connections points to the ground. For example, the post 114 may be embedded in concrete and fastened to the ground with bolts and/or fasteners 120. The bolt cover 142 may hide or disguise how the hinge column 106 and support post 114 is grounded, and the attacker may not be able to inspect how the posts are secured. The bolt covers 142 and/or abutment 122 (e.g., the lockpin 124, secondary structures 130, etc.) may either prevent the attack, prolong the attack, and/or cause the attack to focus on the wrong structure, such as a non-structural secondary structure 130.
The lock 128 in
When the attachment 116 of the arm 108 includes two or four contact surfaces 136 (e.g., at the pin plates 156 or lock tabs 154) and the support 138 includes the other four or two illustrated contact surfaces 136 (e.g., at the other of the lock tabs 154 or the pin plate 156), the joint may include six contact surfaces 136, which reduces the total shear/bearing inversely proportionally. The ability to design the lockpin 124 within the abutment 122 enables a designer to re-distribute loads and/or stresses in the load path. The loads can be more evenly distributed than when the force is distributed entirely onto the shackle 150 of the lock 128. For example, the increased number of contact surfaces 136 may reduce the loads experienced at the abutment 122 by a factor of two, four, six, or more.
The box-cover 132 may be a secondary structure 130 that the lock 128 attaches to the abutment 122. For example, the box-cover 132 may capture the attachment 116 of the arm 108 between the box-cover 132 and the support 138 on the post 114. As illustrated in
Specifically, a heat sensor 162 in thermal communicaiton with the arm 108 sends an alarm signal to activate/trigger an alarm when the arm heated (e.g., from a torch that heats the arm 108 to cut the gate 100). Similarly, a vibration sensor 164 in tactile communicaiton with the arm 108 may send an alarm signal to activate/trigger an alarm when arm 108 is jarred or otherwise moved abruptly. For example, vibration sensor 164 may include a seismic measurement (e.g., seismic sensor) that determines the abrupt movement of arm 108 or other components of the gate 100 and generates and sends the signal. Similarly, a contact switch 166 can send an alarm signal to activate/trigger an alarm when the arm 108 and/or the abutment 122 are not in contact and/or separated by a threshold distance. For example, the contact switch 166 may include a pressure sensor positioned between the attachment 116 of the arm 108 and the abutment 122 that determines the pressure between the attachment 116 of the arm 108 and the abutment 122. The pressure sensor of the contact switch 166 may send an alarm signal to activate/trigger an alarm when the lock 128 has not received the key 134 and/or the measured pressure between two components (e.g., the arm 108, the box-cover 132, the secondary structure 130, and/or the abutment 122) is below a threshold and/or predetermined pressure value.
The cover 168 may completely enclose the abutment 122 and the attachment 116 of the arm 108. In this configuration, the visible portion of the arm 108 includes only the pivot 110 of the arm 108. This may provide a pleasing aesthetic for legitimate customers while notifying potential crooks that the gate 100 is securing the ATM 102. In other words, the cover 168 may hide the abutment 122 at the second end 118 but expose the less vulnerable pivot 110 at the first end 112 to deter would-be criminals and provide a pleasing aesthetic for legitimate customers.
The cover may include a separate security device (e.g., lock 128) or another mechanism for securing and/or opening the cover 168. The gate 100 may further include a frame 170 that surrounds, or partially surrounds, the ATM 102. Specifically, the frame 170 may surround, capture, or enclose the abutment 122, the lock 128, the lockpin 124, and/or other secondary structures 130.
In operation, the authorized user can open the cover 168 protecting the user interface 104 of the ATM 102. The user can provide the key 134 and unlock the shackle 150 of the lock 128 fixed on the secondary structure 130 of the abutment 122 to provide access to the lockpin 124. Removing the lockpin 124 at the second end 118 of the gate 100 frees the arm 108 to rotate. For example, the arm 108 can rotate from the locked position of
When the gate 100 protecting the ATM 102 is attacked, the rotational forces applied to the arm 108 to open the gate 100 do not generate a force on the lock 128. Specifically, the rotational force exerted on the arm 108 does not shear or bear on any part of the lock 128 (e.g., the body 148 or the shackle 150). More specifically, the body 148 and shackle 150 of the lock 128 secure the secondary structures 130 that provide access to the lockpin 124 that secures the arm 108 of the gate 100. The lockpin 124 includes the contact surfaces 136 to secure the arm 108 of the gate 100 in the engaged position 126. The key 134 unlocks the secondary structure 130 to provide access to the lockpin 124 that secures the arm 108 against the post 114 or frame 170 of the gate 100.
The ATM 102 may be captured within a frame 170 having a 42-inch clearance between the front (e.g., the cover 168 and/or interface 104 shown in the closed position of
The lock 128 may couple directly to the lockpin 124 and/or prevent releasing the lockpin 124 from the engaged position 126, without being in the attacking load path. An attacker might contemplate forcing the gate 100 to open to release the lock 128, but when the lockpin 124 is in the engaged position 126 the force rotating the arm 108 is distributed to the frame 170 at the contact surfaces 136. In other words, the shackle 150 and/or body 148 of the lock 128 are not engaged. Similarly, an attack to pick or force the lock 128 open would not affect the lockpin 124. The arm 108 remains securely restrained until the lockpin 124 is removed/released from the engaged position 126. In other words, an attacker that successfully removes the lock 128 may still be unsuccessful in opening the gate 100 if the location of the lockpin 124 is not discovered and/or the lockpin 124 is not disengaged and/or removed.
The abutment 122 includes the lockpin 124 and the lock 128. The lockpin 124 engages the attachment 116 on the arm 108. When the lockpin 124 is in the engaged position 126 bearing on contact surfaces 136 of the lockpin 124 prevent the arm 108 from rotating and/or pivoting about the pivot 110. The lockpin 124 removes the rotational degree of freedom of the arm 108.
The lock 128 couples to the lockpin 124 of the abutment 122. The lock 128 prevents access to the lockpin 124 in the abutment 122, for example, without a key 134. An attack may be prevented without knowledge of the location and/or function of the lockpin 124. Applied forces to rotate the arm 108 do not engage the lock 128. When the lockpin 124 is in the engaged position 126 the arm 108 is secure, regardless of whether the lock 128 is in the locked configuration 146 or the unlocked configuration 144.
The lockpin 124 includes a width 182 inserted in the frame 170 that may be equal to or greater than a width 184 of the body 148 of the lock 128 (see,
The lockpin 124 may include a tongue 188 (e.g., a secondary structure 130 similar to the lock tabs 154) that extends outward from the lockpin 124. The shackle 150 of the lock 128 can directly engage the tongue 188 in the locked configuration 146 to prevent removal of the lockpin 124. In this configuration, the lock 128 secures the lockpin 124 and the lockpin 124 secures the arm 108. When the lockpin 124 is in the engaged position 126, a force that tends to rotate the arm 108 bears against the lockpin 124. The rotational force does not bear against the lock 128 (e.g., either the shackle 150 or the body 148). In other words, the rotational force includes a load path that does not include the lock 128. Any attempt to force open gate 100 stresses the lockpin 124 rather than the lock 128. Similarly, destruction or removal of the lock 128 does not by itself enable rotation of the arm 108 on the gate 100. A force on the lockpin 124 would cause a reaction force on the lock 128 within the pocket 180.
The frame 170, the first stile 192, the second stile 194, and/or the rail 196 may be enclosed (e.g., in a brick wall surrounding the ATM 102). In various embodiments, the frame surrounds the ATM 102 and may further include a third stile 198 at a third rear end 200 and coupled to a rear 202 of the base plate 190 at the third rear end 200 opposite the first stile 192 at the first end 112. An additional fourth stile 204 may be located at a fourth rear end 206. The fourth stile 204 may be coupled to the rear 202 of the base plate 190 at the fourth rear end 206 opposite the second stile 194 at the second end 118 to create a box-like enclosure for the ATM 102. A rear rail 208 extends between the third stile 198 and the fourth stile 204 opposite the rail 196 in the front interface 104 that extends between the first stile 192 and the second stile 194, such that the frame 170 surrounds the ATM 102 or other secured structure.
The frame 170 can support various panels (e.g., back panel 172, right panel 176, and/or left panel 178) that surround ATM 102 and/or partially or completely surround the gate 100 securing the ATM. Regarding
In various embodiments, the left panel 178 is coupled (e.g., welded) to and extends between the first stile 192 and the third stile 198. The right panel 176 is welded to and extends between the second stile 194 and the fourth stile 204. The back panel 172 is welded to and extends between the third stile 198 and the fourth stile 204. In embodiments, the first stile 192, the second stile 194, the third stile 198, and/or the fourth stile 204 are welded directly to the base plate 190. The rail 196 and/or rear rail 208 form a structural frame 170 that surrounds the ATM 102. For example, the rail 196 is welded to the first stile 192 and the second stile 194 and the rear rail 208 is welded to the rear third stile 198 and the rear fourth stile 204.
A cap 210 may extend over the ATM 102 and between the panels and/or frame 170. For example, the cap 210 may be welded to the rail 196 in the front and the rear rail 208. Similarly, the cap 210 may extend between the cover 168, the back panel 172, the left panel 178, and/or the right panel 176. In this way, the cap 210 secures the ATM 102 from above and surrounds the ATM 102 to prevents an attack on the frame 170 and/or other structures.
The installation site often defines the location of the stiles. For example, an installation site with a concrete pad may define the size, location, and/or dimensions of the ATM 102. The location may provide other-dimensional limitations, such as an overhang limiting the height of the ATM and/or side walls or barriers that limit the width of the ATM 102. The depth of the ATM 102 may be limited. For example, a first distance 212 between the first stile 192 and the third stile 198 may be less than or equal to 50, 46, 42, or 38 inches. Similarly, a second distance 214 between the second stile 194 and the fourth stile 204 may be less than or equal to 50, 46, 42, or 38 inches. The first distance 212 and/or second distance 214 define the depth of the ATM and the orientation of the first stile 192 relative to the third stile 198 and second stile 194 relative to the fourth stile 204. In other words, the first distance 212 may be equal to the second distance 214 to define a “thickness” of the ATM 102 in a horizontal direction away from the front interface 104 or cover 168 of the ATM 102.
The stiles may include structural reinforcements. For example, the first stile 192, the second stile 194, the third stile 198, the fourth stile 204, the rail 196, the rear rail 208, the cover 168, and/or the cap 210 may comprise a reinforced steel, titanium, and/or a glass/carbon fiber reinforced plastic material. In one example, the stiles (e.g., 192 and 194) may be welded to the base plate 190, and the rail 196 can be welded to and extends between (e.g., the first stile 192 and the second stile 194). In another example, the stiles (e.g., 192 and 194) include a fiber-reinforced plastic material and are bonded to the base plate 190 and/or the rail 196.
The frame 170 can capture and surround the ATM 102 structure with a clearance 216 that is less than or equal to 1, ¾, ½, or ¼ inches. For example, the frame 170 is located within 0.5 inches or less of the ATM 102 to prevent wrapping a chain around the ATM 102 (e.g., without encircling the reinforced frame 170). In other words, the clearance 216 protects the ATM 102 by restricting the locations of an attack (e.g., chain attack, to the frame 170 and/or gate 100 that are reinforced to withstand the attack).
The lockpin 124 includes a handle 218 that is designed to prevent a chain attack. For example, a chain wrapped around an exterior of the handle 218 would slide off the tapered edge of the handle 218. Similarly, a chain wrapped through the interior of the handle 218 would fail at the thinnest location of the handle 218 and fail to remove or release the handle 218. The fins 220 are also shaped to capture the lock 128 in a way that wards off a chain attack to either the lock 128 or the lockpin 124. In other words, by redistributing the load path the lockpin 124 redirects the failure points of the attack to areas (e.g., the handle 218 and/or the fins 220) that are most resistant to the attack.
Specifically, the support 238 and the alignment tabs 234 support the upper bearing 228 and lower bearing 230 on the pivot 110 of the arm 108 from moving downward axially along the hinge column 106 and the reinforcement 236 and the alignment tabs 234 bear against the upper bearing 228 and lower bearing 230 to restrain axial movement and/or removal of the arm 108. In other words, the alignment joint 222 prevents the removal of arm 108 in any position other than installation position 240.
In general, the alignment joint 222 can provide at least three rotation orientations to the pivot 110 of the arm 108. In the first locked or closed position 242 of
The cut-outs 232 and alignment tabs 234 create a third orientation or installation position 240 of the alignment joint 222 to install or remove the arm 108, as shown in
Reference throughout this specification to “one example,” “an example,” or similar language means that a particular feature, structure, or 2 characteristic described in connection with the example is included in at least one example of the present disclosure. Appearances of the phrases “in one example,” “in an example,” and similar language throughout this specification may, but do not necessarily, all refer to the same example. Similarly, the use of the term “implementation” means an implementation having a particular feature, structure, or characteristic described in connection with one or more examples of the present disclosure, however, absent an express correlation to indicate otherwise, an implementation may be associated with one or more examples.
In the above description, certain terms may be used such as “up,” “down,” “upper,” “lower,” “horizontal,” “vertical,” “left,” “right,” “over,” “under” and the like. These terms are used, where applicable, to provide some clarity of description when dealing with relative relationships. These terms are not intended to imply absolute relationships, positions, and/or orientations. For example, with respect to an object, an “upper” surface can become a “lower” surface simply by turning the object over. Nevertheless, it is still the same object. Further, the terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise. Further, the term “plurality” can be defined as “at least two.” Moreover, unless otherwise noted, as defined herein a plurality of particular features does not necessarily mean every particular feature of an entire set or class of the particular features.
Additionally, instances in this specification where one element is “coupled” to another element can include direct and indirect coupling. Direct coupling can be defined as one element coupled to and in some contact with another element. Indirect coupling can be defined as coupling between two elements not in direct contact with each other, but having one or more additional elements between the coupled elements. Further, as used herein, securing one element to another element can include direct securing and indirect securing. Additionally, as used herein, “adjacent” does not necessarily denote contact. For example, one element can be adjacent another element without being in contact with that element.
As used herein, the phrase “at least one of”, when used with a list of items, means different combinations of one or more of the listed items may be used and only one of the items in the list may be needed. The item may be a particular object, thing, or category. In other words, “at least one of” means any combination of items or number of items may be used from the list, but not all of the items in the list may be required. For example, “at least one of item A, item B, and item C” may mean item A; item A and item B; item B; item A, item B, and item C; or item B and item C. In some cases, “at least one of item A, item B, and item C” may mean, for example, without limitation, two of item A, one of item B, and ten of item C; four of item B and seven of item C; or some other suitable combination.
Unless otherwise indicated, the terms “first,” “second,” etc. are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, for example, a “second” item does not require or preclude the existence of, for example, a “first” or lower-numbered item, and/or, for example, a “third” or higher-numbered item.
As used herein, a system, apparatus, structure, article, element, component, or hardware “configured to” perform a specified function is indeed capable of performing the specified function without any alteration, rather than merely having potential to perform the specified function after further modification. In other words, the system, apparatus, structure, article, element, component, or hardware “configured to” perform a specified function is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the specified function. As used herein, “configured to” denotes existing characteristics of a system, apparatus, structure, article, element, component, or hardware which enable the system, apparatus, structure, article, element, component, or hardware to perform the specified function without further modification. For purposes of this disclosure, a system, apparatus, structure, article, element, component, or hardware described as being “configured to” perform a particular function may additionally or alternatively be described as being “adapted to” and/or as being “operative to” perform that function.
The schematic flow chart diagrams included herein are generally set forth as logical flow chart diagrams. As such, the depicted order and labeled steps are indicative of one example of the presented method. Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more steps, or portions thereof, of the illustrated method. Additionally, the format and symbols employed are provided to explain the logical steps of the method and are understood not to limit the scope of the method. Although various arrow types and line types may be employed in the flow chart diagrams, they are understood not to limit the scope of the corresponding method. Indeed, some arrows or other connectors may be used to indicate only the logical flow of the method. For instance, an arrow may indicate a waiting or monitoring period of unspecified duration between enumerated steps of the depicted method. Additionally, the order in which a particular method occurs may or may not strictly adhere to the order of the corresponding steps shown.
The present subject matter may be embodied in other specific forms without departing from its spirit or essential characteristics. The described examples are to be considered in all respects only as illustrative and not restrictive. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63/224,734, filed on Jul. 22, 2021, the contents of which are incorporated herein by reference in their entirety.
