This description relates generally to a connection rod assembly with a ball lock connector, such as for a storage bin in an aircraft.
Previous connection rod systems require separate components to be assembled via tooling. For example, connection rods may include threaded holes that interface with threaded screws or cotter pins that extend through holes in the rod. Therefore, during assembly installation personnel not only have to carry the loose parts but also the corresponding tools. As such, the chance of dropping, misplacing, improperly installing, etc., the loose parts is increased due to the complexity of the installation procedure. Moreover, the complex installation process may decrease installation efficiency, thereby increasing manufacturing costs. In confined installation spaces, such as in aircraft applications, the aforementioned problems are exacerbated. Moreover, in aircraft applications the loss of components is particularly problematic and may cause unwanted damage to surrounding components during flight. This type of damage is referred to in the art as foreign object debris (FOD) which causes significant amounts of damage to airplane components and systems each year. Accordingly, the inventor has recognized a need to reduce the likelihood of losing components during installation and to increase installation efficiency of connection rod assemblies.
The inventor has recognized the aforementioned problems and have developed a connection rod assembly to at least partially address the problems. The connection rod assembly may include a connection rod, a first ball lock connector including, an outer pin slidably mated with an inner spindle, including an aperture, and coupled to the connection rod, a ball lock bearing at least partially positioned within the aperture, an actuation interface coupled to the inner spindle, slidable with regard to the outer pin, and including a sleeve at least partially surrounding the outer pin, and a spring positioned within the outer pin, where in a locked configuration the spring is unloaded and the ball lock bearing radially extends beyond an outer surface of the outer pin and engages with a detent in a first component, and where in an unlocked configuration the spring is loaded and the ball lock bearing is retained in a groove in the inner spindle.
The actuation interface and the ball locking bearing features of the connection rod assembly enables the assembly to be installed by hand with limited use of tools and in some cases without tools, if desired. Specifically, in one example, a worker may grip the actuation interface and apply axial force thereto to place the ball lock connector in an unlocked configuration, mate the ball lock connector with the component, and then release the axial force to place the ball lock connector in a locked configuration where the ball lock connector is securely attached to the component. Consequently, installation efficiency of the assembly is increased and the likelihood of component misplacement during installation is reduced (e.g., substantially eliminated), thereby decreasing manufacturing and servicing costs of the connection rod assembly. Moreover, providing a connection rod assembly with the features described above enables the likelihood of unwanted component damage caused by lost components to be diminished.
It should be understood that the summary above is provided to introduce in simplified form a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the claimed subject matter, the scope of which is defined uniquely by the claims that follow the detailed description. Furthermore, the claimed subject matter is not limited to implementations that solve any disadvantages noted above or in any part of this disclosure.
Many of the attendant features will be more readily appreciated as the same becomes better understood by reference to the following detailed description considered in connection with the accompanying drawings.
A connection rod assembly is described herein that increases installation efficiency of the assembly while reducing (e.g., substantially eliminating) the chance of losing or misplacing components in the assembly during installation. In one example, the connection rod assembly includes a ball lock connector with an outer pin that is coupled to a component. The ball lock connector also includes an actuation interface coupled to an inner spindle and slidable with regard to an outer pin. The actuation interface allows the ball lock connector to be quickly and efficiently set in a locked and unlocked configuration. In the locked configuration a spring in the ball lock connector is unloaded and a ball lock bearing is urged by the inner spindle such that it radially extends beyond an outer surface of the outer pin and engages with a detent in a component. On the other hand, in an unlocked configuration the spring is loaded and the ball lock bearing is retained in a groove in the inner spindle. In this way, installation personnel may efficiently actuate the ball lock connector to provide quick attachment/detachment with/from the component. When this type of connection rod assembly is used in an aircraft the time needed to install the assembly is reduced and the likelihood of component loss is also reduced, thereby reducing aircraft manufacturing costs. Although the present examples are described and illustrated herein as being implemented in an aircraft system, the system described is provided as an example and not a limitation. As those skilled in the art will appreciate, the present examples are suitable for application in a variety of different types of removable fastener systems including but not limited to industrial fastener systems, automotive fastener systems, home furnishing fastener systems, etc.
Turning to
The first component 108 may be included in a first latch in an aircraft storage bin and the second component 110 may be included in a second latch in an aircraft storage bin. Thus, the connection rod 106 may transfer motion from the first component to the second component, in one example.
The connection rod 106 extends between the first ball lock connector 102 and the second ball lock connector 104 and is coupled (e.g., removably coupled) to each of the ball lock connectors. The connection rod 106 has a constant diameter along the axial length of the rod. However, in other instances the diameter of the rod may vary along the axial length of the rod.
In the illustrated example, the first ball lock connector 102 is similar in size and has similar functionality to the second ball lock connector 104. However, variations (e.g., structural and/or function variations) between the ball lock connectors have been contemplated. For instance, the first ball lock connector 102 may be larger (e.g., have a larger diameter, greater length, etc.) than the second ball lock connector 104 or vice versa to accommodate attachment to differently sized components.
The first ball lock connector 102 includes an actuation interface 112 and the second ball lock connector 104 also includes another actuation interface 114. The actuation interface 112 may be moved in opposing directions (e.g., axial directions) to place the first ball lock connector 102 in locked and unlocked configurations to enable the ball lock connector to be attached to and released from the first component 108. Specifically, in the illustrated example, movement of the actuation interface 112 in a first axial direction 116 inward towards the second ball lock connector 104 places the first ball lock connector 102 in an unlocked configuration. On the other hand, movement of the actuation interface 112 in a second axial direction 118 outward away from the second ball lock connector 104 places the first ball lock connector 102 in a locked configuration. It will be appreciated that similar actuation of the actuation interface 114 in the second ball lock connector 104 may place the connector in locked and unlocked configurations. It will also be appreciated that both the first ball lock connector 102 and the second ball lock connector 104 are in a locked configuration in
A flange 120 is included in the first ball lock connector 102 and a flange 122 is included in the second ball lock connector 104, in the illustrated example. The flanges 120 and 122 may enable installation personnel to easily actuate the ball lock connectors by providing anchor points for their hands to actuate the actuation interfaces 112 and 114. Consequently, personnel may quickly and efficiently actuate the actuation interfaces with limited use of tools or without tools in some cases, if desired. However, in other examples, tools may be used to install the connection rod assembly. The flanges 120 and 122 have a disk shape (e.g., annular shape) in the illustration. However, other flange contours have been contemplated such as flanges with one or more tabs that radially extend away from the connectors, arced flanges, flanges that curve in axially inward or outward directions, etc. In other examples, the flanges may not be included in the first and/or second ball lock connectors.
The actuation interfaces 112 and 114 and flanges 120 and 122 are also shown in
The actuation interface 112 is slideably mated with the outer pin 200 to enable unlocking/locking action in the first ball lock connector 102. Likewise, the actuation interface 114 is slideably mated with the outer pin 202 to enable unlocking/locking action in the second ball lock connector 104. Viewing plane 204 indicates the location of the cross-sectional view shown in
Additionally, a connecting pin 408 of the actuation interface 112 extends through slots 410 in the outer pin 200 and is connected (e.g., fixedly connected) to an inner spindle 412 such that axial movement of the actuation interface 112 causes axial movement of the inner spindle 412. Specifically, the slots 410 extend from an outer surface 414 of the outer pin 200 to an interior surface 416 of the outer pin. The slots 410 also axially traverse a wall of the outer pin 200 to accommodate axial movement of the actuation interface 112 with regard to the outer pin 200.
The actuation interface 112 also include a sleeve 418 mating with the outer pin 200. The sleeve 418 guides the actuation interface 112 through axial movement between the actuation interface and the outer pin 200. Thus, the sleeve 418 circumferentially surrounds the outer surface 414 of the outer pin 200. In this way, the actuation interface 112 is slidingly engaged with the outer pin 200.
The flange 120 is shown extending from the outer pin 200 and may be fixedly coupled to the outer pin 200. Consequently, the flange 120 may serve as an anchor point for a user's hand during actuation of the actuation interface 112, if desired.
The connection rod 106 is also shown mated with an opening 420 in the outer pin 200. The connection rod 106 axially extends into an axial section between the actuation interface 112 and the flange 120. Set screws 422 extend (e.g., radial extend) through screw openings 424 (e.g., radially aligned screw openings) in the outer pin 200. The set screws 422 enable the connection rod 106 to be releasably attached to the outer pin 200.
The set screws may be helically mated with the screw openings 424 and/or recesses (not shown) in the connection rod 106 to enable secure attachment between the connection rod and the outer pin. Additionally or alternatively, the connection rod 106 may be coupled to the outer pin 200 via adhesive, press fitting, clamping, combinations thereof, etc.
The first ball lock connector 102 also include a spring 426 position in an interior cavity 427 of the outer pin 200. The spring 426 is illustrated as a coil spring in
The spring 426 may be loaded and unloaded via axial movement of the inner spindle 412. Loading and unloading of the spring 426 causes the first ball lock connector 102 to be placed in a locked configuration and an unlocked configuration, discussed in greater detail herein. It will be appreciated that axial actuation of the actuation interface 112 causes axial motion of the inner spindle 412. In particular, movement of the inner spindle 412 in an axial direction 429 away from ball lock bearings 428 compresses and loads the spring 426. Conversely, movement of the inner spindle 412 in an axial direction 430 toward the ball lock bearings 428 decompresses and unloads the spring 426.
In the illustrated example, the first ball lock connector 102 includes a plurality of ball lock bearings and specifically includes two ball lock bearings positioned on radially opposing sides of the connector. However, ball lock connectors with a single ball lock bearing or more than two ball lock bearings with or without different ball spacing have been contemplated. For instance, the first ball lock connector 102 may include four ball lock bearings which may be spaced 90° apart with regard to sequential bearings. In other examples, the first ball lock connector 102 may include a single ball lock bearing or three ball lock bearings which may be spaced 120° apart. Providing additional bearings in the connector may increase the strength of attachment between the connector and the component.
The ball lock bearings 428 are retained in apertures 432 in the outer pin 200 in both the locked and unlocked configurations of the first ball lock connector 102. The apertures 432 may taper in a radially outward direction to retain the bearings. Thus, in each aperture an inner width of the aperture may be greater than an outer width of the aperture. Moreover, the outer width of the aperture may be less than a diameter of the bearing.
The ball lock bearings 428 may move radially inwards when transitioning to a locked configuration and radially outwards when transitioning to an unlocked configuration. When moved outward into a locked configuration the ball lock bearings 428 engages with the first component 108. An opening 434 in the first component 108 receiving a portion of the first ball lock connector 102 is also shown in
The first ball lock connector 102 shown in
The locking surface 500 in the inner spindle 412 therefore urges the ball lock bearing 428 radially outward in the locked configuration.
The unlocking surface 504 has a smaller radius 520 than a radius 522 of the locking surface 500 with regard to the central axis 406 first ball lock connector 102, shown in
As shown, the ball lock bearing 428 is retracted into the aperture 432 in the outer pin 200 such that the bearing is spaced away from the detent 502 in the first component 108. In the unlocked configuration the ball lock bearing 428 is still retained in the aperture 432 but moved further radially inwards such that it is adjacent to (e.g., in face sharing contact with) the unlocking surface 504. Thus, the ball lock bearing may be held in the groove 506 in the inner spindle 412 when unlocked.
The motion transferred from the actuation interface 702 to the mechanisms 704 may cause the configuration of the mechanisms to change. For example, when the mechanisms 704 are latches actuation of the actuation interface may open the latches and allow the aircraft storage bin to be opened. Continuing with such an example, release of the actuation input may cause the latches to close. Additionally, in the illustrated example, the mechanisms 704 are positioned on either side of the aircraft storage bin 700. However, other locations of the mechanisms may be used. To install the connection rod assembly 100 in the aircraft storage bin 700 the assembly may be placed in the interior of the storage bin and attached to the actuation interface 702. The actuation interfaces in the connection rod assembly may then be actuated to quickly and efficiently connect the assembly to the first and second components 108 and 110 and the mechanisms 704, correspondingly. In this way, the connection rod assembly 100 can be rapidly assembled in the storage bin 700. However, other installation procedures may be used in other examples.
At 802 the method includes placing a connection rod assembly into a storage bin in a passenger compartment of an aircraft. Next at 804 the method includes actuating the actuation interface in the first ball lock connector of the connection rod assembly and at 806 the method includes moving the first ball lock connector into an unlocked configuration. Thus, it will be appreciated that the ball locked connector may be moved into an unlocked configuration when the actuation interface is actuated. For instance, installation personnel may grip the actuation interface and move it axially away from the end of the first ball lock connector having ball lock bearings positioned therein. Movement of the actuation interface in this manner loads the spring in the connector and allows the ball lock bearings to move inwardly and be retained in a groove in the inner spindle. In the unlocked configuration the ball lock bearing may be positioned radial inward from an outer surface of the outer pin. It will be appreciated that actuation of the actuation interface may be sustained to keep the ball lock connector in the unlocked configuration. As such, actuation of the actuation interface may be sustained through step 808.
Next at 808 the method includes mating the first ball lock connector with a first latch in the storage bin. For example, an end of the first ball lock connector with the ball lock bearings may be inserted into an opening in the first latch of the storage bin.
Next at 810 the method includes moving the first ball lock connector into a locked configuration. In this way, the first ball lock connector may be securely attached to the storage bin latch with a quick and efficient process, thereby increasing installation efficiency. Next at 812 the method includes the method includes actuating the actuation interface in the second ball lock connector in the connection rod assembly.
At 814 the method includes moving the second ball lock connector into an unlocked configuration and at 816 the method includes mating the second ball lock connector with a second latch in the storage bin.
At 818 the method includes moving the second ball lock connector into a locked configuration. Method 800 enables the ball lock connectors in the connection rod assembly to be quickly attached to latches in the aircraft storage bin. It will be appreciated that in some examples, steps 804-810 and 812-818 may occur at overlapping time periods (e.g., a simultaneous time period). However, in other examples, steps 804-818 may occur at sequential time intervals.
Furthermore, in some examples, the connection rod may be attached to the first ball lock connector and/or the second ball lock connector prior to step 802. Additionally, in one example, the attachment between the connection rod and the ball lock connectors may occur prior to end-use installation, such as installation in the aircraft storage bin.
