RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. Provisional Application No. 61/887,144, filed Oct. 4, 2013, which the disclosure of is hereby incorporated by reference herein in its entirety.

INTRODUCTION

To aid in the use of cameras, peripheral devices may be used. Some peripheral devices attach to the lens and/or flash equipment of cameras. Devices that may be attached to a lens include lens hoods, lens adaptors, step-rings, lens filters, and lens extension tubes. Devices that may be attached to flash equipment include light diffusers, light filters, and light directing devices.
Attaching peripheral devices to cameras presents challenges. For example, certain attachment mechanisms require the use of straps and bulky equipment. The straps are easily lost, and some users find the use of straps clumsy and difficult to use.
Other attachment mechanisms are made of a rigid material that is manufactured for a specific make of camera lens or camera flash. These mechanisms are not interchangeable among makes of multiple camera lenses and camera flashes.
Further, current attachments allow only for one device to be attached to a camera element at a time. This configuration prevents multiple peripheral devices (e.g., filters and diffusers) from being attached to a single piece of flash equipment.
It is with respect to these and other considerations that the technologies described below have been developed. Also, although relatively specific problems have been discussed, it should be understood that the embodiments should not be limited to solving the specific problems identified in the introduction.

DETAILED DESCRIPTION

As used in this disclosure, a camera is an optical instrument that records images. The images may be stored locally, transmitted to another location, or both. These images may be still photographs or moving images such as videos or movies. The medium upon which the images are stored may be video tape, digital media (RAM, ROM, CD, solid state drives, etc.), film, or any other now known or later developed medium suitable for storing images.
With reference to FIG. 1A and FIG. 1B, each illustrates an embodiment of a camera accessory mounting element 100, with FIG. 1B illustrating an embodiment of a camera accessory mounting element attached to a camera flash. FIGS. 1A and 1B illustrate a body 102 having a face 104, a base 106, an exterior wall 108, and an interior wall 110 that defines an opening 112. Additionally, a camera accessory mounting element 100 includes an attachment element 114. In an embodiment, the attachment element 110 is disposed in a housing element 116.
As illustrated, the body 102 is of a unitary construction. The body 102 may be configured such that it can elastically deform to attach to various parts of a camera. In an embodiment, the body 102 is made of a material that has an elastic property, such that it can deform or stretch during use but substantially return to its original shape. For example, the body 102 is in the form of a stretchable, flexible band. Accordingly, the body 102 may be made from silicone, polyurethane, neoprene, rubber, elastomeric, elastic, elastic polymer, flexible rubber, or any other suitable material now known or later developed. In other embodiments, the body is rigid. Still in others, the body has portions that are flexible and portions that are rigid.
In certain embodiments, the body need not be a unitary construction, but may be made of various types of materials. For example the body may have rigid elements. Such an embodiment may include a flexible body with rigid elements affixed to the face of the body. These rigid portions may be used as an attachment element. Other examples include using rigid elements to provide structural support to the body.
FIG. 1A additionally illustrates an exterior wall 108 and an interior wall 110. The body 102 may include one or more interior walls 110 that define an opening 112. For example, the body 102 may have a single interior wall 110, which may form a substantially circular or oval shaped opening 112. In another embodiment, the single interior wall 110 may form a rectangular shaped opening 112 with rounded corners. Still in other embodiments, there may be multiple interior walls 110 such that it forms a square opening 112, a hexagonal opening 112, or another polygonal shaped opening 112.
The opening 112 is defined by a height H, a width W, and a depth D. In an embodiment, the height of the opening 112 may be about 1.5 inches, the width may be about 2 inches, and the depth may be about 0.7 inches. In embodiments where the body is flexible, the dimensions may be stretched from the original dimensions. Other dimensions are contemplated.
FIG. 1B illustrates an attached configuration of body 102. In an embodiment, the use of flexible materials in the body 102 allows the camera accessory mounting element 100 to be used with camera elements each having a variety of forms such as lenses, flash equipment, etc. For example, the body 102 is flexible, which allows the body to stretch to fit a component 118 of a camera. Additionally, a user may stretch the body 102, orientate the body 102 so that a camera component 118 fits into the opening 112 of a body, and then release the body 102. This allows the body 102 to form a robust connection to the component 118 to which it is mounted. Such a configuration may allow the body 102 to mount to a variety of camera component designs. Camera components include lenses and flash equipment.
As illustrated in FIG. 1B, the body 102 has been stretched to fit over a component 118 that is a flash component of a camera. One way to place a body 102 on a component 118 of a camera, such as the light of the flash equipment, is to stretch the body 102 and dispose the component 118 of the camera in the opening 112. The body 102 compresses around the component 118 of the camera to form a robust connection with the component 118.
Additionally, FIG. 1B illustrates the face 104. The face 104 is adapted to face outwardly from the component 118, while the base 106 is proximate to the component 118. Though FIG. 1B illustrates the body 102 attached to a flash device of a camera, a body may be attached to other portions of the camera including the lens of a camera.
Additionally, FIGS. 1A and 1B illustrate an attachment element 114. The attachment element 114 may be a variety of elements such as a hook-and-loop fastener, a magnet, a snap connector, a button, a cavity, an adhesive, a clamp, and a threaded connection. Additionally, other types of coupling elements are contemplated. For example, attachment element 114 may be snap connectors, hook-and-loop fasteners, or threads located on the face 104 of the camera accessory mounting element 100.
As illustrated, the attachment element 114 is a cylindrical magnet, and may be a rare earth magnet. In an embodiment, the magnet 114 is removably inserted into a housing element 116. In other embodiments, the body 102 is manufactured to permanently house one or more magnets in one or more housing elements 116. Still in other embodiments, the attachment element 114 magnet is made of a flexible, elastic magnet that is incorporated into (or makes up in entirety) the body 102.
As illustrated, the two housing elements 116 protrude from the body 102. Each housing element 116 may be adapted to receive the attachment element 114. More or less housing elements may be used depending on the desired location of the attachment element 114. Location of the attachment element 114 is chosen in such a way as to enable the attachment of a peripheral device such as a grid, a light directing dish, a lens hood, a lens adaptor, a step-ring, a lens filter, a lens extension tube, a light diffuser, a light filter, and a light directing device. For example, in embodiments having magnets as the attachment elements 114, the magnets 114 will align with magnets (or another ferromagnetic material) of a peripheral device.
