With reference to
As illustrated, the torque limiting device 130 includes a plurality of driving members 132 and a plurality of driven members 134. In the illustrated embodiment, the driving members 132 are integrally formed with the outer body 102 and the driven members 134 are integrally formed with the inner body 104. It is to be appreciated that in some embodiments, the driving members 132 can be integrally formed with the inner body 104 and the driven members 134 can be integrally formed with the outer body 102.
The outer body 102 has an inner diameter D1. The inner diameter D1 can be measured from an inner surface 136 of the outer body 102. In some embodiments, the driving members 132 extend a distance L1 from the inner surface 136. In certain embodiments, D1 can be at least about 1″ [25.4 mm], or less than or equal to 2.75” [70 mm], in other embodiments D1 can be approximately 1.75” [44.5 mm], wherein D1 can be scaled based on the application. The distance L1 can be selected in accordance with a dimensioning of the driving members 132. L1 can be scaled depending on the application. In certain embodiments L1 can range between 0.02” [0.5 mm] and 0.2” [5 mm], in other embodiments it can be approximately 0.05” [1.3 mm]. In the illustrated embodiment, the driving members 132 are shown as being semicircular in geometry. It is to be appreciated that this geometry can be modified in accordance with the principles disclosed in the Specification.
In some embodiments, the driven members 134 can include a base 138 and a tip 140. The base 138 is located at the hub 106. The tip 140 is a free end of the driven members 134. The tip 140 includes a surface 142. The surface 142 is configured to be adjacent to the inner surface 136. In some embodiments, the surface 142 is configured to engage with the inner surface 136. In some embodiments, the surface 142 is configured to be spaced from the inner surface 136 and to not contact the inner surface 136 except at the driving members 132. Accordingly, in some embodiments, the inner body 104 has an outer diameter D2 measured at the surface 142 of the tip 140. In some embodiments, the inner diameter D1 is larger than the outer diameter D2. In some embodiments, the inner diameter D1 and the outer diameter D2 are substantially the same. As used herein, substantially the same means the same subject to, for example, manufacturing tolerances or the like.
The driven members 134 include a first surface 144 and a second surface 146. The driving members 132 are configured to contact the second surface 146 of the driven members 134 when the handle 100 is rotated in the R1 direction. In some embodiments, the R1 direction corresponds to a closing direction of a valve. In response to being rotated in the R1 direction, the driving members 132 contact the driven members 134 and force the driven members 134 to rotate in the R1 direction. Upon reaching a torque threshold, the driving members 132 are configured to disengage from the driven members 134. As a result, the driving members 132 rotate in the R1 direction but the driven members 134 do not rotate in the R1 direction.
In some embodiments, to accomplish the disengagement, the driven members 134 are flexible. The driven members 134 can be flexible due to the materials selected. In some embodiments, the flexibility can be a result of a curvature of the driven members 134. To configure the torque limiting device 130 for a particular torque threshold, the stiffness of the material for the driven members 134 can be selected in combination with a thickness T of the driven members 134, an angle θ of the driven members 134, a radius of curvature of the 134, or the like.
In some embodiments, the torque threshold can be selected based on a particular valve being used with the handle 100. In some embodiments, the torque threshold can be based on an acceptable range of torques for a variety of valves. That is, in some embodiments, the handle 100 can be configured for a specific valve and in some embodiments the handle 100 can be configured for a series of valves.
In some embodiments, when the driving members 132 disengage from the driven members 134, feedback is provided to the user turning the handle 100. In some embodiments, the feedback is audible. For example, a clicking sound may be generated due to the disengagement of the driving members 132 and the driven members 134. In some embodiments, the feedback is tactile. For example, the user may feel the movement of the driven members 134 relative to the driving members 132. In some embodiments, the feedback is both audible and tactile.
In some embodiments, when the handle 100 is rotated in the R2 direction the driving members 132 are configured to contact the first surface 144 of the driven members 134. In In some embodiments, the R2 direction corresponds to an opening direction of a valve.
In some embodiments, the inner body 104 can include a member 148. The member 148 can protrude from the hub 106. In some embodiments, a corresponding member can be included on the valve so that a user cannot open the valve too far (i.e., over rotate in the R2 direction). Such a feature can serve as a stop for the rotation in the R2 direction and prevent damage to the valve from opening the valve beyond its fully open position.
In some embodiments, the torque threshold can be set based on one of the R1 direction or the R2 direction. In some embodiments, a first torque threshold can be set for the R1 direction and a second torque threshold can be set for the R2 direction. In some embodiments, the first torque threshold and the second torque threshold can be different.
The valve 180 can include a first threaded connection 182 and a second threaded connection 184. The first threaded connection 182 and the second threaded connection 184 can be used to connect the valve 180 to a fluid container 186 and a device, respectively.
The valve 180 can include an indicator 188. In the illustrated embodiment, the indicator 188 shows that the valve 180 is in the “closed” state. In some embodiments, when a user rotates the handle 100 to transition from the “closed” state to an “opened” state, the indicator 188 can visually be modified to indicate “opened.” In some embodiments, the indicator 188 can include text similar to the illustrated embodiment. In some embodiments, the indicator 188 can include an “O” or a “C” for opened or closed, respectively. In some embodiments, the indicator 188 may not include any text and can instead include color coding. For example, in the closed state the indicator 188 can be red and in the opened state the indicator 188 can be green. It is to be appreciated that these colors are examples, and the actual colors can vary beyond the above example. In some embodiments, the indicator 188 can be configured to rotate along with the handle 100 and the valve 180. As such, in a partially opened or partially closed state, the indicator 188 may show an indication that the valve 180 is in an intermediate state.
In some embodiments, the handle 100 can include an indicator 190. The indicator 190 can be a scannable indicator. In some embodiments, the indicator 190 can be scanned by a device to determine a type of fluid being stored in the associated fluid container. In some embodiments, the 188 can be a barcode, QR code, or the like. In some embodiments, the indicator 190 can be an RFID tag or the like. In some embodiments, the indicator 190 can be a visual color coding that is indicative of the fluid contained within the fluid container.
In some embodiments, the valve 180 can include a member 192. The member 192 can be configured to engage with the member 148 (

With the cover 204 removed, an inner body 208 is visible. The inner body 208 includes a hub 210. The hub 210 forms an inner opening 212. The inner body 208 is disposed in a location so that a threaded bolt from a valve can be received through an opening 214. In some embodiments, a nut or other fastener can be threaded to the corresponding bolt and subsequently secure the handle 200 to the valve. In some embodiments, the nut can be in direct contact with a surface 216 to provide a clamping force to hold the handle 200 to the valve. In some embodiments, the nut can be indirectly in contact with the surface 216 to provide the clamping force.
An outer surface of the inner body 208 can include a plurality of driven members 218 and the outer body 202 includes a plurality of driving members 220. The driving members 220 are sized and shaped to fit within the driven members 218. In some embodiments, the driven members 218 may be recessed into an outer surface of the inner body 208. For example, the inner body 208 includes a plurality of channels 222 recessed into an outer surface of the inner body 208. In some embodiments, protruding edges 224 define the channels 222 therebetween. In the illustrated embodiment, the channels 222 have a generally semicircular geometry. It is to be appreciated that this is an example, and the actual geometry can vary according to the principles described in this Specification. In some embodiments, the inner body 208 can have an appearance of a gear or sprocket.
The outer body 202 is rotatable relative to the inner body 208 in some situations. For example, when the handle 200 is turned to close a valve, the outer body 202 may disengage from the inner body 208 upon reaching a torque threshold. In some embodiments, the torque threshold can be selected based on a particular valve being used with the handle 200. In some embodiments, the torque threshold can be based on an acceptable range of torques for a variety of valves. That is, in some embodiments, the handle 200 can be configured for a specific valve and in some embodiments the handle 200 can be configured for a series of valves. In some embodiments, when the torque threshold is reached, feedback can be provided to the user. For example, in some embodiments audible feedback can be provided. In some embodiments, tactile feedback can be provided. In some embodiments, the feedback can be both audible and tactile.
In some embodiments, the outer body 202 can be made of a metal material. In some embodiments, the outer body 202 can be made of a non-metal material. In some embodiments, the inner body 208 can be made of a metal material. In some embodiments, the inner body 208 can be made of a non-metal material. In some embodiments, the outer body 202 and the inner body 208 can be made of the same material. In some embodiments, the outer body 202 and the inner body 208 can be made of different materials. In some embodiments, the outer body 202 can be made of a metal material and the inner body 208 can be made of a non-metal material. In some embodiments, the outer body 202 can be made of a non-metal material and the inner body 208 can be made of a metal material.
In some embodiments, the outer body 202, the inner body 208, or a combination thereof, can be produced by an additive manufacturing process such as 3D printing.

The driving members 220 are configured to contact the edges 224 of the driven members 218 when the handle 200 is rotated in the R3 direction or the R4 direction. In some embodiments, the R3 direction corresponds to a closing direction of a valve. In response to being rotated in the R3 direction, the driving members 220 contact the driven members 218 and force the driven members 218 to rotate in the R3 direction. Upon reaching a torque threshold, the driving members 220 are configured to disengage from the driven members 218. As a result, the driving members 220 rotate in the R3 direction but the driven members 218 do not rotate in the R3 direction.
In some embodiments, the torque threshold can be set based on one of the R3 direction or the R4 direction. In some embodiments, a first torque threshold can be set for the R3 direction and a second torque threshold can be set for the R4 direction. In some embodiments, the first torque threshold and the second torque threshold can be different.
In some embodiments, to accomplish the disengagement, the driving members 220 are flexible. The driving members 220 can be flexible due to the materials selected. To configure the torque limiting device 230 for a particular torque threshold, the stiffness of the material for the driving members 220 can be selected in combination with a thickness T of the driving members 220, a number of the driving members 220, or the like.
In some embodiments, the torque threshold can be selected based on a particular valve being used with the handle 200. In some embodiments, the torque threshold can be based on an acceptable range of torques for a variety of valves. That is, in some embodiments, the handle 200 can be configured for a specific valve and in some embodiments the handle 200 can be configured for a series of valves.
In some embodiments, when the driving members 220 disengage from the driven members 218, feedback is provided to the user turning the handle 200. In some embodiments, the feedback is audible. For example, a clicking sound may be generated due to the disengagement of the driving members 220 and the driven members 218. In some embodiments, the feedback is tactile. For example, the user may feel the movement of the driven members 218 relative to the driving members 220. In some embodiments, the feedback is both audible and tactile.
In some embodiments, when the handle 200 is rotated in the R4 direction the driving members 220 are configured to contact the edges 224 of the driven members 218.
