The present invention generally relates to accessories for laptops and other computing devices. More specifically, the present invention relates to an ergonomic and Radiofrequency-Electromagnetic Frequency (RF-EMF) shielding kit or assemblage for use with desktops, laptops, tablets, or other similarly sized electronic devices.
Personal computers (PCs) have been in use for many years now, and the general population has come to rely on them in order to perform many basic functions such as shopping, record keeping, and video entertainment. Even with the rise in use of smaller computing devices such as smartphones, smartwatches, and tablets, laptops are still in use because of several factors such as screen size, speed, memory capacity, and computing power.
While the laptop provides superior utility for certain applications and uses, it suffers from two major drawbacks in terms of user comfort and safety. First, as with all computing devices having a keyboard, carpal tunnel syndrome (CTS) and other repetitive stress injuries can occur. This is primarily due to the fact that a laptop must be relatively flat, which makes the use of ergonomic keyboards virtually impossible. CTS is caused by cumulative damage to the finger tendons as they pass through a short, narrow, rigid channel in the wrist, the carpal tunnel. With the hand-oriented palm down, the roof of the carpal tunnel is formed by the arch of the carpal bones and the floor by the tough transverse carpal ligament. The carpal tunnel contains the tendons for the fingers, the radial artery, and the median nerve, which transmits sensation for the thumb and the first two and half fingers. Sensation for the remaining digits is transmitted via the ulnar nerve, which runs outside of the carpal tunnel.
As the hand deviates from normal either horizontally towards the thumb or towards the little finger (ulnar deviation), or vertically up or down, then the pressure on the carpal tunnel increases. Vertical deviations especially create significant increases in carpal tunnel pressure. Accelerations from extension to flexion are thought to pose the greatest risk for CTS, and when the hand is in a wrist neutral position, then there is minimum pressure on the tendons and the median nerve in the carpal tunnel. With occupational overuse of the fingers, minor trauma to the tendons and the sheaths may accumulate and eventually produce CTS.
As the tendons or their sheaths become irritated and inflamed, the resulting swelling increases the pressure on the median nerve, which initially causes tingling, then numbness over time. Eventually disabling pain results when the fingers are moved. Laptop users are particularly at risk because of the large number of finger movements made in a short time, and the fact that the keyboard is flat, which results in very unnatural positioning of the hands.
The second problem with laptop use is the fact that the entire device is in close proximity to the user, in contrast to a desktop where only the keyboard need be close to the user. When considering that the laptop includes a large screen, a power source, and an RF transmitter, a great deal of EMF or RF radiation is emitted from the device.
Accordingly, it is desirable to provide a means to reduce CTS while providing RF shielding for laptop users.
The present invention provides a kit for laptop and PC users. The kit is an all-in-one assemblage of various components designed to mitigate the effects of carpal tunnel syndrome (CTS) and provide radio frequency or EMF shielding. The kit includes a pair of removable palm rest or wrist pads, which are ergonomically shaped and adjustably attachable to a laptop. A pair of thigh pads having a relatively flat top side are designed for positioning on a user's lap. The thigh pads provide EMF shielding and also raise the laptop closer to the user's eyes. A wrist pad for use with a mouse pad is also included. The mouse pad completes the kit and also serves as a base upon which the other components may be assembled for storage.
In an embodiment, the present invention comprises an assemblage of components for providing improved ergonomic positioning and RF shielding for a laptop and a desktop computer users, comprising: (a) a first and a second wrist pad, said wrist pads configured for removable attachment to left and right corners of a laptop, said wrist pads having a main body lower portion formed of RF shielding material, with an upper portion having an arcuate shape and positioned to accommodate pivoting of a user's hand; and, (b) a pair of lap cushions formed of RF shielding material.
In an embodiment, the assemblage upper portion of the first and second wrist pads is attached to said lower portion by an elasticated connector, which may further comprise a friction material on an exterior surface able to reduce slippage of the first and second wrist pads relative to the laptop regardless of the dimensions of the laptop. And the elasticated connectors may be removeable from the lower portion and affixable to a laptop surface in a proper alignment with a plurality of typing keys.
In an embodiment, the main body lower portion of the first and second wrist pads has a triangular shape corresponding to corners of the laptop; and the main body lower portion has a thickness of about 1.0 mm to about 1.5 mm.
In an embodiment, the assemblage further comprises a mouse pad upon which said assemblage components fit. And an underside of said mouse pad has a plurality of fastening material on one side to affix said assemblage components for storage. The assemblage may further comprise a third wrist pad substantially rectangular shaped for positioning on said mouse pad; and the third wrist pad comprises an interior cavity as storage space with a closure. And the assemblage components are geometrically shaped for positioning on said mouse pad in non-overlapping relation with respect to said mouse pad when said assemblage is in a storage mode. Additionally, the assemblage components may comprise fastening material on an underside side for attachment to the mouse pad underside when said assemblage is in the storage mode.
In an embodiment, the lap pads are able to be used as a fourth wrist pad or a forearm pads with a table-top computer.
In an embodiment, the first and second wrist pads upper portion have an arcuate shape and stiffness able to position a user's hand in a proper ulnar, radial nerve positions to prevent and/or alleviate symptoms for carpal tunnel syndrome (CTS). The first and second wrist pads may have a thickness of about 2 mm to about 4 mm for the radial nerve in a user's thumb, forefinger; and about 5 mm to about 8 mm for the ulnar nerve in the user's pinkie finger; and the elasticated portion has a thickness of about 1 mm.
In an embodiment, the first and a second wrist pad are detached from the main bodies; and the wrist pad upper portions are able to attach to a computer keyboard. The upper portion further comprises an extension strip to attach the first and second wrist pad to the side of a computer keyboard. In another embodiment, the wrist pad upper portions comprise an extension strip to attach the first and second wrist pad to the side of a computer keyboard.
It is a major object of the invention to provide an assemblage of components to enhance user comfort and safety when using a laptop or similar electronic devices.
It is another object of the invention to provide an assemblage of components to enhance user comfort and safety when using a laptop which includes components designed to reduce carpal tunnel syndrome.
It is another object of the invention to provide an assemblage of components to enhance user comfort and safety when using a laptop, in which the assemblage provides RF shielding.
It is another object of the invention to provide an assemblage of components to enhance user comfort and safety when using a desktop computer or similar device.
The present invention is directed to a kit or assemblage of components designed to provide enhanced comfort and safety for users of laptops, desktop PCs, and other similarly configured electronic devices which require tactile interaction. While primarily designed for use with laptop computers, the assemblage, generally indicated by the numeral 10, may also be used with desktop computers.

The upper padded portion 32 (i.e. the curved straps) of the wrist pads 20, 22 is attached to the main body 28, 30 by an elasticated connector or portion 34, which allows for some variation in the size and thickness of the laptop 24. Elasticated portion 34, in another embodiment, is also removeable, adjustable via a Velcro® strip positioned beneath pad 32. Preferably, the elasticated portion 34 further comprises a non-slip outer surface 35 that provides friction to reduce slippage of the wrist pad 20, 22 relative to the laptop 24 regardless of the dimensions of the laptop allowing different configuration of hand sizes and laptop sizes. Thus, the outer surface 35 helps to keep wrist pads 20, 22 in position on the laptop 24 by providing friction material to reduce the possibility of the wrist pads 20, 22 sliding off of the laptop 24.
The upper portion 32 has a resting surface 37 upon which the user may place their wrists, is configured for the positioning of the heel of the user's wrist, and accordingly has an arcuate or curved shape to allow for pivoting the wrist from side to side without upper portion 32 hindering movement of the hand or fingers. That is, the curved shape of upper portion 32 and resting surface 37 corresponds to the arc that a human wrist or wrist pad would follow as the user's hand pivot in Ulnar (e.g. 30 degrees) and Radial (20 degrees) hand divination reducing carpal tunnel micro trauma and inflammation thereof. Also, by raising the position of the heel of the hand, the user's hand is elevated to a more neutral ergonomically sound position versus a 10-20 degrees wrist extension relative to the plane of the laptop's 24 keyboard. To achieve the proper positions of the hand, upper portion 32 is padded, such as with a memory foam, or is formed of a more sturdy material layer with proper ulnar, radial nerve positions carved into it, then with a top layer of padding. In an exemplary embodiment to treat CTS, the curved pad 32 has a thickness of from about 2 millimeters (mm) to about 4 mm for the thumb, forefinger position (e.g. radial nerve); and about 4 mm to about 6 mm for the pinkie finger (e.g. ulnar nerve). The elasticated portion 34 has a thickness of about 1 mm. As illustrated in

Storage: referring now particularly to
Alternatively, mouse pad 42 and components 20, 22, 40, and 50 may be stored in a box, bag or container without damaging them. It should be noted that a key aspect of the invention is that the components 20, 22, 40 and mouse pad 42 are shaped both for function and to be stored in a compact fashion.
Alternative Wrist Pads
A variety of alternative wrist pads are envisioned within the scope of the present invention to allow user adjusting the location of the pads to their comfort level and to properly align the keyboard components. As illustrated in
An additional embodiment, extension strip 80 may be used to position the left and/or right strap near the middle of the keyboard, and it may connect to the main body 28, 30; or strip 80 may substitute in lieu of the main bodies (e.g. strip 80 encircles the underside of the laptop edges). Strip 80 is able to connect to cushion 32 by methods well known in the art: e.g. Velcro® strips 55, magnets 70, etc. . . . .
In another embodiment, the wrist straps 32 comprise top cushions without components on the computer underside. For example,
