Definitions
- Embodiments of the present invention generally relate to mounting systems and methods. Some embodiments of the present invention employ a clamp that can be used for selective interconnection to and support of a device, such as a light, a mobile phone, a tablet computer, camera, etc.
- a device such as a light, a mobile phone, a tablet computer, camera, etc.
- an electronic device such as a light, a mobile phone, tablet computer, a camera, etc. in a "hands-free" mode. This is often accomplished by attaching the device to a table, a pole, etc. Examples might include: 1) attaching a global positioning systems (GPS) unit to a handle in a car; 2) attaching a tablet computer to a headboard of the bed so the tablet computer can be used in a hands-free manner; 3) attaching a lamp to a stage pole; and 4) attaching a tablet computer to a pole or table.
- GPS global positioning systems
- the clamp comprises a first jaw and a second jaw selectively interconnected to a rack of a ratcheting mechanism.
- the first jaw may be hingedly interconnected to the rack.
- the second jaw is connected to the rack by way of a carrier that is slidingly associated with the rack.
- the lower jaw may be hingedly interconnected to the carrier.
- the carrier is also associated with a pawl that operatively engages rack teeth, i.e., gears, in a ratcheting fashion.
- the two jaws are configured to attach to flat objects such as table tops, round objects such as light poles, or objects of other geometric profiles and orientations
- a connector for selective interconnection to the device mount or support system may be provided on either the first jaw or the second jaw. Although shown extending from an upper surface of the upper jaw, the connector may be recessed within the upper jaw without departing from the scope of the invention. More specifically, the connector is adapted to interconnect to the supporting and mounting system that selectively accomodates an electronic device.
- the connector can be placed on any portion of the clamp, and not limited to the upper jaw. In some embodiments of the present invention the connector is placed on the side of the jaws. In other embodiments, the connector is operatively interconnected to a track such that the connector can be selectively moved to accommodate the user's desires.
- the clamp may provide multiple connectors to further expand the connection possibilities the clamp provides.
- the clamp can support the weight of various items.
- one embodiment of the present invention includes a lower jaw having an outward extent that is positioned outward from an outward extent of the upper jaw.
- the extended lower jaw increases the force supported by the lower jaw which facilitates securing heavier objects.
- the lower jaw may also be expandable such that its outer extent can be further separated from the rack to support heavier loads.
- Some embodiments of the present invention include an upper jaw having fingers.
- the fingers engage a surface and create frictional loads that help secure the clamp to an object.
- the fingers also help to react to loads.
- Fingers of some embodiments are selectively adjustable wherein the angle between the fingers may be expanded to spread out reactive loads or enhance frictional interactions.
- the fingers telescope outwardly such that the outer extent of the upper jaw is greater than the lower jaw, which facilitates interconnection of the clamp in an upside down configuration wherein the upper jaw is placed under a table, for example.
- some embodiments of the present invention employ upper jaws and lower jaws that are spring-loaded or that employ a leaf spring such that when the upper jaw or lower jaw are engaged tightly onto surface, the activated spring firmly secure the jaws to the surface or object to which they are connected.
- Spring-loaded jaws also help seat the pawl into the rack.
- the upper jaw and lower jaw are configured to interconnect with curved, flat, or uneven surfaces.
- the upper jaw and lower jaw may include a curved or triangular profile to accommodate a round or cylindrical surface as provided by a bar or pole, for example.
- a soft or compliant pad associated with the upper jaw or the lower jaw may be provided that helps protect the surface to which the clamp is interconnected, to provide additional fictional interaction between the jaws and the surface, as well as allow compression in the system to aid in generating the clamping forces needed.
- the upper jaw of the clamp is engaged onto the surface, such as a tabletop.
- the lower jaw is then moved to operatively engage the lower surface of the table. Movement of the lower jaw along the rack will also move the spring- biased pawl along the rack teeth.
- the shape of the teeth and the shape of the pawl allow the pawl to move upwardly along the rail with the teeth moving the pawl over successive teeth.
- the spring associated with the pawl forces the pawl to return to and indent provided between each tooth.
- the lower jaw is prevented from moving away from the upper jaw by the pawl's interaction with the rack teeth.
- the carrier is also associated with a crank which employs a cog that also selectively engages the rack.
- acuation of the crank engages the cog into space between another set of rack teeth. Successive motion of the crank engages the cog onto the rail and causes the pawl to move one or more teeth. When the crank returns to its undeflected position by way of a spring, the pawl is firmly engaged onto the rack and is prevented from sliding. Successive crank motion will cause the carrier to move along the rack towards the upper jaw to tighten the jaws. A pawl release is depressed to remove the pawl from the rack, which allows the lower jaw to be separated from the upper jaw.
- the unique shape of the cog and its relation to the rack and crank allow for an interaction that allows the cog to reset with every crank pull and avoid contact with the rack inner teeth and associated jamming.
- the cog which has three teeth in some embodiments, is curved relative to at least three planes, and yet moldable.
- some embodiments of the present invention provide an upper jaw that is hingedly interconnected to the rack and a lower jaw that is hingedly interconnected to the carrier. After the upper jaw is moved away from the lower jaw, the upper jaw and lower jaw are rotated inwardly towards the rack inner surface to configure the clamp for storage.
- the clamp described may be selectively scaled in size to suit the needs of the application to which is it is intended. Further, the clamp may be made of metal, plastic, a combination of plastic and metal, or any other suitable material.

- a clamp 2 of one embodiment of the present invention includes an upper jaw 6 and a lower jaw 10.
- the upper jaw 6 is interconnected to a rack 14.
- the lower jaw 10 is connected to a carrier 18 that is operatively engaged to the rack 14.
- the carrier 18 also rotatably supports a crank 22 that includes a cog 26 selectively and operatively interconnected to the inside surface 30 of the rack.
- the carrier 18 further employs a pawl 34 and that is operatively interconnected to an outside surface 38 of the rack 14.
- the upper jaw 6 is rotatably interconnected to the rack 14 and the lower jaw 10 is rotatably interconnected to the carrier 18, which will be described in further detail below.
- the pawl 34 has an end 42 that selectively engages a space between adjacent teeth 46 of the outer surface 38 of the rack 14.
- the teeth 46 are shaped to allow movement of the pawl 34 in one direction and to prevent movement of the pawl 34 in an opposite direction.
- the interaction of the pawl 34 and the teeth 46 maintain the distance between the upper jaw 6 and the lower jaw 10 such that the carrier 18 cannot be moved along direction A when the pawl 34 is engaged.
- pressure from below the carrier 18 or below the lower jaw 10 along direction B will move the lower jaw 10 towards the upper jaw 6.
- the pawl 34 is biased by a spring 50 wherein pressure along direction B will selectively move the end 42 along the rack 14 incrementally over successive teeth 46 falling into the spaces between adjacent teeth in a ratcheting manner as it moves.
- the carrier 18 is prevented from sliding from the rack 14 by a stop 54 at the end of the rack 14.
- a pawl release 58 is actuated, which moves the end 42 of the pawl 34 from the rack 14, allowing the carrier 18 to move along the rack 14.
- the carrier 18 also accommodates a crank 22 that includes a cog 26 that operatively engages teeth 62 on the inside surface 30 of the rack 14.
- the crank 22 is rotated away from the rack 14 along arc C (see pg 4), which engages the cog 26 onto the teeth 62 to incrementally urge the lower jaw 10 towards the upper jaw 6.
- the crank 22cog 26 is also biased by a spring 66 such that when pressure is removed from the crank 22, it will return to a relaxed position adjacent toaway from the rack 14. In the relaxed position, the cog 26 is separated from the teeth 62 wherein only the pawl 34 holds the carrier 18 in place. Interaction between the cog 26 and the crank helps move the crank to a position adjacent the rack when pressure is released.
- Figs. 3A - 3D illustrate the operation of the cog 26 of one embodiment of the present invention.
- the crank 22 When the crank 22 is in a neutral, non-deflected position (Fig. 3A), the cog 26 and its teeth 28 are not engaged onto the inner teeth 62 of the rack 14. Movement of the crank 22 along arc C will rotate the cog teeth 28 into engagement with the rack inner teeth 62 (Fig 3B). The cog teeth 28 will then engage the rack inner teeth 62 and urge the carrier 18 upwardly along direction B as shown in Fig. 3. As the carrier is moved upwardly, the pawl end 42 will transition over a tooth 46. Further movement of the crank
- the upper jaw 6 and the lower jaw 10 include elastomeric members 70, 74 that allow them to engage surface without damaging the same. Elastomeric members 70, 74 also increase the friction between the jaws and the surface to which the clamp is interconnected which enhances the connection.
- the clamp 2 may also include a connector 78.
- the connector 78 may include four keys 82 that received a supporting device with a corresponding bayonet fitting.
- Figs. 5 and 6 show the clamp 2 of one embodiment of the present invention interconnected to a horizontal surface 86, such as a table.
- a horizontal surface 86 such as a table.
- the upper jaw 6 is placed on an upper surface of the table.
- the carrier 18 is slid upwardly and the lower jaw (not shown) is engaged to the lower surface of the table 86.
- the crank 22 may be used to incrementally move the lower jaw towards the lower surface of the table 86.
- the clamp may still be somewhat loose. If so, the crank 22 is rotated outwardly along direction C (see Fig. 2) to incrementally move the lower jaw into a tight engagement with the lower surface of the table.
- the clamp force is also reacted by the upper jaw 6 engaged to the upper surface of the table.
- Fig. 7 shows how the crank 20 receives and supports additional items.
- a collar 100 and flexible member 104 are interconnected to the clamp 2.
- the claim 2 may have a bayonet style interconnection device or any other connection mechanism known in the art to receive and secure a corresponding connection mechanism of the desired support or mounts.
- the flexible member 104 is interconnected to another collar 100 and a suctioning dock 108 that secures an electronic device 112.
- Figs. 2, 8, and 9 illustrate how embodiments of the present invention are folded.
- the upper jaw 6 is rotatably interconnected to the rail 14 and may be selectively rotated along an arc D.
- the lower jaw 10 is rotatably is rotatable along arc E. In this way, the clamp 2 can assume a low profile storage configuration.
- Fig. 10 is an exploded view of the clamp and Figs. 1 1-18 are representations of the components in Fig. 10.
- Fig. 1 1 shows a crank 22 is a U-shaped injection molded part made of about 30% long-fiber glass filled nylon. Receiving holes are provided for pins that allow the crank 22 to interface with other components. The other end of the crank 22 is covered by a polyurethane rubber over-molded grip.
- the crank 22 serves as the force input to the folding clamp.
- the crank 22 interfaces with the carrier 18 via a crank pin 116.
- the crank 22 also interfaces with the cog 26 via the cog pin 120 and a cog spring that returns the cog 26 to a relaxed position.
- Fig. 12 shows the carrier 18 which may be an injection molded part made of about 30% glass filled nylon. It is geometrically complex with three sets of mounting holes and a large channel in the center.
- the carrier 18 holds the crank 22, pawl 34, and lower jaw 10 in the correct position relative to each other. Additionally, the carrier 18 slides along the rack 16 in response to force input through the crank 22, for example, which allows the clamp jaws to be pushed together
- Fig. 13 shows the cog 26 of one embodiment that is a small aluminum die cast piece with curved gear teeth along the bottom side and a lateral mounting hole.
- the cog may also be injection molded in glass-filled (GF) Nylon.
- the cog 26 transmits the input force of one end of the crank 22 onto the rack 14 forcing the carrier 18 to push the lower jaw 10 towards the upper jaw 6.
- the curved teeth on the lower side of the drive cog 26 mesh with corresponding teeth on the rack 14.
- further motion of the crank 22 moves the carrier 18 along the rack 14 and moves the lower jaw 10 towards the upper jaw 6.
- the cog 26 rotates so its teeth rotate past the teeth on the rack 14.
- Fig. 14 shows the rack 14 of one embodiment made of 30% glass filled nylon piece overmolded onto a stamped steel insert.
- the rack 14 is stiff but flexible such the rack 14 will bow when the upper jaw and the lower jaw are firmly engaged onto a surface. The bowed rack will tend to recoil, i.e. attempt to return to its non-deflected state, which further biases the top jaw towards the bottom jaw to increase clamping force.
- the rack 14 has a generally rectangular profile with gear teeth on either side. Both of the sets of gear teeth may have a curved profile. Curved teeth allow for a larger surface area and disbursement of forces that allows for a stronger structure in a reduced envelope.
- the top of the rack 14 has a boss with a hole for a mounting pin.
- the bottom of the rack 14 has two longitudinal blind holes.
- the stamped steel insert protrudes out of the rack 14 on one of the large faces near the rack bottom.
- the rack 14 provides the running surface that allows the two jaws of the clamp to move together. As the carrier 18 slides along the rack 14, the lower jaw 10 moves relative to the upper jaw 6. Additionally, the rack 14 has teeth that allow the ratcheting action that creates and maintains force between the lower jaw 10 and the upper jaw 6.
- Fig. 15 shows the lower jaw assembly of one embodiment that comprises an injection molded lower jaw 10 with an overmolded elastomeric lower pad 74 on one side.
- the lower jaw 10 is made of 30% glass filled nylon and the overmolding 74 is polyurethane rubber.
- the lower jaw assembly has a large (about 25mm) hole in its center and a pin hole running laterally through one end.
- the upper jaw 6 is a generally round part made of 30% glass filled nylon that is overmolded onto an M6 threaded brass insert.
- the upper jaw 6 has a laterally oriented hole for a mounting pin.
- the primary functions of the upper jaw 6 provide a clamping surface opposite the lower jaw assembly and to provide a mounting surface for attachment to external elements, such as those shown in Fig. 7.
- One side of the upper jaw 6 has two 10mm wide fingers 152 with a flat face on either side of a cylindrical face, allowing them to clamp both flat and round objects. Each finger 152 receives an elastomeric member 70.
- the elastomeric members 70 are polyurethane rubber pieces with a 60A durometer. As the two jaws of the clamp move together the elastomeric members compress providing feedback to the user about the level of force applied. Once the clamp is in position over an object, such as the table, the elastomeric material of the elastomeric members maintain their compression, which helps maintain a clamping force.
- the elastomeric members also have a tread pattern for increased grip on rough surfaces.
- the pawl 34 is an injection molded part made from 30% glass filled nylon. It has a lateral pin hole with a lever on one side and a gear tooth on the other. There may be a round feature at the end of the lever on the pawl 34 that acts as a button. There are also two small cuts on the underside of the pawl 58 to allow for pawl springs.
- the pawl 34 contributes to the ratcheting action of the clamp by preventing motion of the carrier that would allow the jaws to spread apart.
- the geometry of the pawl end 42 and the corresponding teeth on the rack allow the pawl 34 to be dragged over teeth on the rack when the jaws are moving closer, but prevents the jaws from spreading apart.
- the button on the pawl 34 is depressed, the pawl end 42 rotates away from the rack and the jaws may open.
- Figs. 19-21 show a clamp 2 of another embodiment of the present invention that includes an upper jaw 6 that provides the ability to change location of the connector 78.
- the upper jaw 6 includes a track 156 that operatively receives the connector 78.
- the connector 78 can be placed at or near the outward extent of the upper jaw (Fig. 19), on the upper surface of the upper jaw 6 (Fig. 20), at or near the inward extent of the upper jaw 6 (Fig. 21), or various positions therebetween.
- This embodiment thus provides the user a multitude of connector 78 orientation options which further enhances their ability to position an electronic device, for example. Once in a desired position, the connector 78 is will locked in place.
- the track 156 may be positioned transverse to, or at an angle relative to, the track shown and that a plurality of tracks may be provided without departing from the scope of the invention.
- Figs. 22-26 shows a clamp 200 of yet another embodiment of the present invention that employs deployable arms.
- the upper jaw 206 and/or the lower jaw 210 may include arms 212, 216 that flair out from their respective jaws to increase the contact footprint of the jaws onto a surface.
- the arms 212 of the upper jaw 26 are angled outwardly, which helps react transverse clamp loads emanating from the connector 78, for example.
- the arms 2 and 16 of the lower jaw 210 react transverse loads and increase the load footprint, which helps react longitudinal loads emanating from the connector 78.
- longitudinal refers to the direction perpendicular to the upper surface of the upper jaw 206 and generally parallel to a side surface of the clamp 200
- transverse refers to a direction orthogonal to the longitudinal direction.
