1. Technical Field
The present disclosure relates to mounting devices for use with equipment having line-of-sight requirements, such as, for example, optical and electronic equipment, and more particularly, for use with cameras, spotting scopes, camcorders, binoculars, or the like.
2. Description of Related Art
Mounting devices for cameras and other optical and electronic equipment allow the camera, or other equipment, to be moved into various positions and secured in order to hold the camera, or other equipment, steady for good, clear photos or accurate measurements. A variety of devices are available, such as single ball mounts, double ball mounts, post and arm ball mounts, segmented arm mounts, and multiple clamp devices
Single ball mounts can be used to rotate a camera 360° and tilt it to various degrees. A single ball mount may also have a clamping device that holds the ball in a socket on one end and a support post on the other end, which allows the clamp to swing through 180° while the ball rotatable 360°. While single ball units operate smoothly and rotate a full 360°, they have a restricted tilt motion.
A double ball mount may incorporate adjustable locking arms or clamps between the balls, which allows both balls to move independently and allows the camera to be moved and locked into various positions. Double ball devices can be moved into almost any position, but they cannot be easily adjusted while in use (i.e., when a camera is mounted) since both balls are generally free at the same time making precision adjustments difficult.
Post and arm ball mounts allow the ball to rotate freely, but the arm can only rotate in one axis and not swivel. Segmented arms allow for adjustments in multiple positions, but do not lock securely when in the desired position. Multiple clamp devices allow for adjustments in many positions, but are not lightweight or portable enough to easily carry and use in the field.

In the present description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the disclosure. However, upon reviewing this disclosure one skilled in the art will understand that the various embodiments disclosed herein may be practiced without many of these details. In other instances, some well-known structures and materials associated with mounting devices have not been described in detail to avoid unnecessarily obscuring the descriptions of the embodiments of the disclosure.
In the present description, the terms “about” and “approximately” mean±20% of the indicated range, value, or structure, unless otherwise indicated. In the present description, the terms “a” and “an” as used herein refer to “one or more” of the enumerated components. The use of the alternative (e.g., “or”) should be understood to mean either one, both, or any combination thereof of the alternatives. As used herein, the terms “include” and “comprise” are used synonymously, which terms and variants thereof are intended to be construed as non-limiting.
Various embodiments in this disclosure are described in the context of use with cameras, and attachment clamps. However, as will be understood by those skilled in the art after reviewing this disclosure, various other line-of-sight devices, or other equipment, may be suitable for use with the disclosed mounting devices, and various other base mounts, such as, for example, tripods, may be substituted for the attachment clamp.
As illustrated in
An exemplary mounting device 2 of the instant disclosure is shown in
Referring to
Each of the clamp members 12, 12′ can have an aperture 28, 28′, which can be disposed at, or at about, a mid-point between the end portions 12, 12′, 16, 16′ of the clamp members. The apertures 28, 28′ are alignable to allow a shaft 32 of a coupling member 30 to be inserted through the apertures 28, 28′ to couple the clamp members 12, 12′ together, as shown in
Referring now to
A second linking member 38 (having a ball portion 38a with a circumferential ridge 38b, and rod 38c extended from a surface of the ball portion 38a) can also be coupled to a circular grip 40′ (e.g., thumbwheel). Again, an end portion of the rod 38c, or other extension member, can extend outward past the circular grip 40′, and this outwardly extended portion can be formed with an external threaded surface (for mating with a female internal threaded surface). Again, the rod 38c itself can be a standard camera mounting screw like the type noted above, or the extension member can be configured like the external threaded portion of such standard camera mounting screw. In other embodiments, the “rod” is not threaded, including in embodiments where it can be molded as one part to the sphere or truncated sphere. The rod 38c, or extension member can be pivotably connected to a base, such as, for example, an attachment clamp 6, tripod (not illustrated), or other base. In some embodiments, a female threaded socket could be substituted for the rod 38c.
a-8c show several alternative embodiments for the second linking member. For example, referring to
In some embodiments, the ball portions 36a, 38a can be “clamped” within the concave regions 20, 20′, 24, 24′, of the clamp members 12, 12′, and the clamp members tightened together using the knob 34, to secure the ball portions within the adjustable clamp assembly 2. The ball portions 36a, 38a provide two joints about which the clamp members 12, 12′ can pivot and tilt to provide a greater range of positions than would be provided by a single ball joint. The concave regions 20, 20′ of the first end portions 14, 14′ of the clamp members can be aligned to receive respective surface portions of the ball portion 36a of the first linking member 36, with the ball portion 36a fitting snugly between inside surfaces 22 of the concave regions 20, 20′. Also, the concave regions 24, 24′ of the second portion portions 16, 16′ of the clamp members can be aligned to receive respective surface portions of the ball portion 38a of the second linking member 38, with the ball portion 38a fitting snugly between inside surfaces 22 of the concave regions 24, 24′.
The circumferential ridge 38b of the ball portion 38a can rest snuggly within respective grooves 26 of each of the concave regions 24, 24′, or can be disposed between grooves on either concave region 24, 24′. When the clamp members 12, 12′ are loosened, they can be tilted relative to the ball portion 38b of the second linking member 38, with an axis of tilt being defined by the groove 26 intersections 26′. In this manner, the clamp members can be titled about the ball portion 38a in toggling fashion, or “clicked”, between high resistance positions and low resistance positions. In low resistance positions, the circumferential ridge 38b rests between corresponding grooves 26, where the ball portion 38a and can be easily slidable relative to the clamp members 12, 12′ when the clamp members are loosened. In high resistance positions, when the circumferential ridge 38b rests within corresponding grooves 26, the ball portion 38a does not slide as easily as the ridge 38b must be pushed out of the grooves 26 (e.g., via sloped walls of the ridge 38b, as discussed below) in order for the ball portion 38a to move, even when the clamp members 12, 12′ are in a loosened position, due to a biasing member that maintains force to bias the clamp members 12, 12′ toward each other (as discussed further below).

Referring to
The second linking member 38 can be pitovably attached to, among other things, an attachment clamp 6, tripod or other base assembly. As shown in
In some embodiments, the clamp members 12, 12′ can be toggled relative to the second linking member 38 through different positions off vertical at increments of, for example, 10, 15, 18, 20, 22.5, 30, 36, 45, 60, or 90 degrees, or any other increments. In some embodiments, such as that displayed in
In some embodiments, the second linking member comprises a spherical head and a rod extending from the head surface, wherein the spherical head comprises a smooth peripheral surface with a ridge on the circumference of the spherical head. In further embodiments, the spherical head may be a truncated sphere or may be replaced by a disc having edge configuration that is similar to the ridge 38b. In still further embodiments, the ridge may be continuous and extend around the entire circumference of the spherical head (essentially forming a raised ring-like protrusion on the spherical surface) or the ridge may be discontinuous, or have sections, at spaced apart portions of the sphere along the same line as that of the disclosed ridge 38b.
Although specific embodiments of the present disclosure have been described supra for illustrative purposes, various equivalent modifications can be made without departing from the spirit and scope of the disclosure, as will be recognized by those skilled in the relevant art after reviewing the present disclosure. The various embodiments described can be combined to provide further embodiments. The described structures and methods can omit some elements or acts, can add other elements or acts, or can combine the elements or execute the acts in a different order than that illustrated, to achieve various advantages of the disclosure. These and other changes can be made to the disclosure in light of the above detailed description.
