BACKGROUND
1. Field of the Invention
The present invention relates to a camera mounting and handling, and more specifically to a camera mount and adjustable strap.
2. Description of Related Art
Cameras may be handled by a user in a variety of ways, and may have different straps or tripod mounts attached depending upon the situation. In some uses, a short wrist strap may be used which adds security to holding the camera while photographing. In some uses, a longer strap may be used which allows the camera to be suspended from the neck of the user while not being used. In some uses, a user may want to mount the camera onto a tripod.
In another aspect, a strap may be used to support a camera wherein the strap is laid over both the neck and a shoulder of the user. A drawback of this aspect is that a strap long enough to allow for use of the camera will be long enough that the camera, when dangling from the strap while not in use, will be able to have too much mobility. The camera may be subject to too much motion, such that it is a distraction to the wearer. This may also present the risk of damage to the camera should it hit an object with this large range of possible motion.
What is called for is a body strap for a camera which may retract while the camera is not being used for photography such that the camera is held firmly against the body.
SUMMARY
The present invention is directed towards a retractable pulley strap assembly adapted to mount to the bottom of a camera, or other device, and to be used in a variety of configurations. The strap is adapted to allow for extension, and increase of the effective strap length, while the camera is in use. The strap is adapted to retract to a shorter effective length while the camera is not in use, such that the camera is held tightly against the user's body.

DETAILED DESCRIPTION
In some embodiments of the present invention, as seen in FIG. 1, a pulley camera strap 100 is adapted to support a device, such as a camera. The pulley camera strap 100 may include a main strap portion 103 and a shoulder cushion 102. The pulley camera strap is adapted for use with a camera 101. As seen in FIG. 1, in a retracted configuration the pulley camera strap is adapted to go over one shoulder of the user while holding the camera 101 snugly against the body of the user.
As seen if FIG. 2, the pulley camera strap allows for use of the camera 101. A camera 101 may be used by a user 110 with the strap around the user's neck and shoulder while being held in the hand 111 of the user 110. The strap is in an extended configuration such that the loop formed by the strap is longer and adapted to be pulled from the body of the user, providing use of the camera while still around the body. The main strap configuration 103 has been altered by the user to have extended the effective length of the strap.
As seen if FIG. 3, the pulley camera strap allows for the alteration of the loop length of the main strap portion 103. The retracted configuration is adapted to hold the camera snugly around the body of the user, such that the camera does not swing. The extended configuration is adapted to allow for the use of the camera by the user without having to have removed the strap from around the shoulder and neck of the user.
As seen in FIG. 4, the retracted configuration of the pulley camera strap has a shorter effective strap length. The shoulder strap 102 is adapted to be worn over the shoulder of the user, and may be wider or padded to increase comfort for the user. A first pulley set 120 adjacent to the shoulder strap 102 and a second pulley set 121 adjacent to the camera mount 122 allow for the effective loop length of the pulley camera strap to be adjusted by the user. The pulley system may be able to be extended with a single hand of the user, allowing for the user to use the camera 101. The pulley system may exhibit enough friction that after extension or retraction the strap length stays at the desired effective length under the expected loads seen by the system.
FIG. 5 illustrates the system in an extended configuration, wherein the effective loop length of the strap is at its largest length. FIG. 6 illustrates aspects of a pulley strap system according to some embodiments of the present invention.
In some embodiments of the present invention, as seen in FIGS. 7-11, a camera strap 200 is adapted to be worn around the neck and/or shoulder of a user. The strap pad 201 allows for comfortable placement on the shoulder of the user. The strap 202 creates a loop in conjunction with the strap pad 201. The length of the loop may be lengthened or shortened by the user by pulling on the strap tab 203. The strap tab 203 also includes a mounting attachment for a camera, which may be a threaded post 204.
The strap 202 is adapted to slide through the strap tab 203 such that the loop length may be altered. The system is adapted to have the loop remain at the selected length when the user is not moving the strap tab 203 along the strap 202. The strap tab 203 will remain in place on the strap 202 under the forces typically seen by the camera strap under normal use conditions. As the strap tab 203 moves along the strap 202, the relationship of the portion of the strap that is a single strand, towards one end of the strap pad, to the portion of the strap that is overlaid with three strands, changes. As this relationship changes, the loop length, or the effective length of the loop, changes, by changing this relationship. Thus, with an unchanging length of strap the loop length may be altered by manipulation of the location of the strap tab along the strap.
The strap slider 204 and the strap tab 203 provide routing for the strap 202 such that movement of the strap tab 203 along the strap 202 results in a change of length of the loop created by the strap and strap pad. Changes in the length of the loop allow for different uses, such as snug stowage of the camera strap and camera along the body of the user, or a looser strap allowing for use of the camera by the user with the strap still on the body of the user. FIG. 12 illustrates the camera strap 200 in a configuration that it may take when on a user.
In some embodiments of the present invention, as seen in FIGS. 13 and 14, the strap pad may be formed with a bend to allow for a different resting configuration on the body of a user.
As evident from the above description, a wide variety of embodiments may be configured from the description given herein and additional advantages and modifications will readily occur to those skilled in the art. The invention in its broader aspects is, therefore, not limited to the specific details and illustrative examples shown and described. Accordingly, departures from such details may be made without departing from the spirit or scope of the applicant's general invention.
