MAGNETIC HOLDER
An instrument holder has a magnetic element that is coupled to a looped elastic strap. The looped elastic strap may be stretched to accommodate instruments of varying shapes and sizes. In one embodiment the looped elastic strap is capable of being stretched to a length greater that approximately twice the minimum length of the looped elastic strap. This allows the magnetic element to be secured to instruments of various shapes and sizes by placing the looped elastic strap around an instrument.
Commonly, writing instruments, such as pens, have an integrated clip that enables the pen to be clipped to a pocket or writing pad. Other writing instruments, such as pencils, highlighter pens, dry-erase markers for white boards are much less likely to have integrated clips. Other instruments, such as flashlights and laser pointers may or may not have clips. Instruments with or without clips may be difficult to carry when the user has no easily accessible pockets, and are easily misplaced. For example, workers in many fields wear uniforms without pockets. Examples include medical workers who wear ‘scrubs’ or laboratory coats.
One way to carry an instrument is to attach a magnet to the instrument so that it can be attached to a material that can be magnetized, that is, a ferrous material. For example, a ferrous metal holder may be worn by a person (either clipped or pinned to clothing, or supported by a lanyard, for example) and the magnet may be used to attach the instrument to the ferrous metal holder.
Prior methods for attaching a magnet to an instrument include spring loaded clips for pens and rubber lined sleeves for pencils. Both of these approaches have the limitation that they only allow the magnet to be attached to instruments of a particular size.
In an alternative approach, a magnet is integrated with a pen during manufacture.

DETAILED DESCRIPTIONBefore describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method steps and apparatus components related to an improved magnetic holder for writing instruments and the like. Accordingly, the apparatus components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
In this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
The present invention relates to a magnetic holder for attaching an instrument to a magnetic object. The instrument may be a pen, pencil, highlighter pen, laser pointer, magnifying glass, flashlight or other instrument.
In one embodiment, the looped elastic strap has a stretched length that greater than approximately twice its relaxed length. For example, in one embodiment the looped elastic strap 302 has a relaxed length of less than 30 mm and is capable of being stretched to a length greater than 60 mm. This allows the magnetic element to be secured to instruments having a circumference in the range 30 mm to 60 mm or higher by placing the looped elastic strap around the instrument. A combination of tension in the looped elastic strap and friction between the strap and the instrument serves to secure the magnetic element to an instrument.
Either the magnetic object or the magnetic element, or both the magnetic object and the magnetic element are magnetized so that an instrument to which the magnetic element is attached may be removably coupled to the magnetic object via the magnetic element.
In a further embodiment, the looped elastic strap is capable of being stretched to a length greater than twice the relaxed length.
The width of the looped elastic strap is selected such that friction between the strap and the instrument is sufficient to hold instruments of different sizes and shapes. The width may be as little as 2 mm and as much as 30 mm or greater. The strap may be constructed of, or lined with, a rubber-like material (such as natural rubber, urethane or silicone) that resists slipping. The looped elastic strap may be narrow, like a ring, or have an extended width, like a sleeve.
The magnetic element is constructed of a magnetizable material and may be a magnet. The magnetic element may be a ferrous metal such as Neodymium-Iron-Boron (Nd2Fe14B), Aluminum-Nickel-Cobalt (AlNiCO) and iron, Samarium-Sobalt (SmCo) and iron. The magnetic element may be a Ceramic (ferrite) permanent magnet, such as a mixture of Strontium, Carbonate and Iron Oxide. The magnetic element may be a flexible material such as Strontium Ferrous Oxide and K-resin (rubber), or a Strontium Ferrite powder mixture with polymer bonding. These materials and others are well known to those of ordinary skill in the art.
The instrument holder may be at least partial constructed of a luminescent or ‘glow-in-the-dark’ material or may be marked with such a material. This enables the instrument holder to be seen more easily in low-light conditions.
The magnetic elements 102 and 504 may be the same shape or different shapes, the same size or different sizes. When both elements are magnets, they may have the same strength or different strengths. For example, the first magnetic element 102 may be a ½″ diameter disc, while the second magnetic element may be a ¾″ disc. The size and strength of the magnets may be selected according to the use. For example, a wearable magnet may require a greater strength than a magnet on a fixed surface.
Typically, an instrument such as highlighter pen or flashlight has a larger circumference than a pencil. Accordingly, the looped elastic strap 302 should be extensible enough that it can accommodate instruments of different shapes and different circumferences.
The spring clip 904 may also be used to attach the magnetic element 504 to clothing or other surfaces.
In one embodiment, the distal end of at least one of the jaws 914 wraps around the back edge of the vane 906. A spring element 916 is positioned between the jaws 914. The spring element may be a coil spring for example. One end of the spring element 916 is restrained by the body of the clip, while the other end applies a biasing force to an end piece or stop 918. The end piece or stop may be a rubber like material. The stop 918 may be glued to the spring element 916 or fitted as a plug into the end of the spring element. In operation, the stop 918 is pushed against the front edge of the vane 906 by the spring element 916. Thus, the clip is securely attached to the vane. The pressure provided by the spring element 916 and the stop 918 reduces any tendency of the clip to rattle. In addition, when the distal ends of the jaws 914 are moved apart to remove the clip, the spring element and end-piece aid in the removal of the clip by pushing the clip 904 away from the vane 906.
In this embodiment at least one of the jaws 914 has a hooked end (the distal end). A first spring element is operable to bias the first and second clamping elements together across of the flow deflection vane 906, while the second spring element 916 is operable to bias the stop and a hooked end of a jaw together across a second cross-dimension of the flow deflection vane, as illustrated by arrows 920 in
In some embodiments, the clamping elements are sized to clamp vanes ranging in width from 1.7 cm to 2.7 cm. The spring element and stop allow the vent clip to be attached securely to narrower vanes, while still allowing use with wider vanes.
The jaws 914 may be at least partially coated or wrapped in a soft rubber-like material positioned to contact the flow deflection vane 906. This reduces any tendency of the clip to slip along the vane and further reduces any tendency to rattle. In a further embodiment, the functions of spring element and stop are performed by a single compliant element, such as a single shaped block of rubber or silicone.
The magnetic element may be attached to a surface using other attachments. For example, in
In a further embodiment, shown in
In a still further embodiment, shown in
In view of the examples provided above, it will be apparent to those of ordinary skill in the art, that the magnetic element may be supported in various ways.
