Description

Bedside cabinet

Technical Field

The present invention relates generally to a bedside table for shielding or attenuating EMF radiation of a mobile telephone device placed therein.

Background

Mobile phone radiation effects and human health are a concern for mobile phone users, particularly with the increasing popularity of EMF-radiating mobile phone devices, including devices with 5G functionality.

The present invention seeks to provide a way or at least an alternative which will overcome or substantially ameliorate at least some of the disadvantages of the prior art.

It should be understood that if any prior art information is referred to herein, such reference does not constitute an admission that such information forms part of the common general knowledge in the art in australia or any other country.

SUMMERY OF THE UTILITY MODEL

The utility model provides a bedside cupboard, can prevent or at least substantially attenuate the EMF radiation that emits from it.

The bedside cabinet comprises a base and a drawer slidably received in the base, the base having a top panel positioned above the drawer, the drawer comprising a front wall, a rear wall and side walls and a rectangular bottom panel positioned therebetween, wherein the bedside cabinet further comprises an EMF shielding layer comprising at least a front EMF shielding layer applied to the front wall of the drawer and a top EMF shielding layer applied to the top panel such that when the drawer is closed, the front EMF shielding layer moves to the top EMF shielding layer thereby partially enclosing an EMF shielding enclosure formed by the EMF shielding layer.

In addition, side, rear and bottom EMP shielding layers are operatively applied to the respective walls of the drawer or to the interior of the base.

Thus, the drawer can be opened and closed in the normal manner, except that when closed, the front, back, side and bottom EMF shield layers are moved into alignment with the top EMF shield layer, thereby forming an EMF shield enclosure therebetween. Thus, when the drawer is closed, the EMF shield housing prevents or at least attenuates EMF radiation from the mobile telephone device. However, when open, EMF radiation from the mobile telephone device can propagate through the open drawer.

The bedside cabinet may be configured to allow a power cord to be wound into the drawer to power the mobile telephone device placed therein. In one embodiment, the bedside table includes a rear junction box compartment in which a power strip, power adapter, or the like may be placed. The power cord leading therefrom may be routed upwardly in the base and upwardly over the upper edge of the rear wall of the drawer.

In this regard, the EMF shield can be configured such that the top EMF shield layer extends over the rear wall of the drawer so as to prevent or attenuate EMF radiation from escaping through the gap on the upper edge of the rear wall of the drawer.

Similarly, a top EMF shield layer may extend over the front wall of the drawer to cooperate with the front EMF shield layer to prevent EMF radiation from escaping from the gap therebetween.

The bedside table of the present invention has a drawer therein which, when closed, forms an EMF-shielding housing, so that, during sleep, one or more mobile telephone devices can be placed therein such that the EMF-shielding housing prevents or at least substantially attenuates EMF radiation emanating therefrom.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for descriptive purposes only.

Referring to fig. 1-3, a bedside table 100 includes a base 101 supported on a table foot 102. The chassis 101 has a drawer 103 slidably received in the chassis 101. The base 101 has a top plate 104 positioned above the drawer 103. Drawer 103 includes a front wall 105, side walls 106, a rear wall 107, and a rectangular floor 108 therebetween.

The drawer 103 slides in and out of the chassis 101 in the manner shown in fig. 1 and 2. In the particular embodiment shown, the bedside table 100 comprises a single drawer 103, and wherein the base 101 has side walls 109 on both sides of the drawer 103, and the top plate 104 forms the top of the bedside table 100 between the side walls 109. The height of the side walls 109 and the position of the drawer 103 may form a void 110 below the drawer 103 for openly storing various items therein.

Referring to fig. 4, the rear of the bedside table 100 may be configured to expose an open junction box compartment 111, and the compartment 111 may be formed between the bottom of the rear wall 112 of the bedside table 100 and the chassis 113. The compartment 111 may include a bottom panel 114 embedded in the bedside table 100, and the bottom panel 114 may include an access hole 115 therethrough. Thus, the power strip 116 may be placed therein and its wires may be routed to the accessible docking point via the access hole 115. A power adapter 117 plugged onto power strip 116 may provide power to a mobile phone device 119 by providing power via a power cord 118 that wraps up into bedside table 100 and drawer 103.

Referring to fig. 5-7, the bedside table 100 includes an EMF shield layer 120 that forms an EMF shield enclosure 126 when the drawer 103 is closed.

The EMF shield layer 120 may comprise a metal foil or mesh layer. A metal foil or mesh layer may be interposed between outer layers such as plastic fabrics.

In a preferred embodiment, the EMF shielding layer 120 attenuates 2G, 3G, and 4G frequencies in the UHF or low microwave band, such as from 600MHz to 3.5 GHz.

In a further embodiment, the EMF shield layer 120 attenuates 5G frequencies in or near the millimeter wave band of about 24 to 52 GHz.

In an embodiment, overlapping layers of EMF shield layer 120, each layer configured to attenuate a different frequency, may be employed. Thus, the layers of the EMF shield 120 can attenuate mobile phone radiation emanating from, for example, 4G and 5G phones.

Specifically, referring to fig. 5, the EMF shield layer 120 may include a top EMF shield layer 121 operatively applied to the top plate 104 (such as by being adhered thereunder in the manner shown in fig. 5).

In embodiments where the bedside table 100 includes multiple drawers 103, a top EMF shield 121 may be applied to the bottom surface of the drawer 103 above.

The EMF shield 120 can further include a front EMF shield layer 125 and an opposing back EMF shield layer 122 with a side EMF shield layer 123 therebetween. A bottom EMF shield layer 124 may be positioned therebetween. In the embodiment shown in FIG. 5,

EMF shielding layer

122 and 125 may be adhered to the inner surface of drawer 103.

Referring to FIG. 6, when the drawer is open, the drawer

EMF shielding layer

122 and 125 are moved away from the top EMF shielding layer 121 so that EMF radiation from the mobile telephony device 119 can propagate outwardly from the open drawer. However, in the manner shown in FIG. 7, when the drawer 103 is closed, the drawer

EMF shielding layers

122 and 125 are moved beneath the top EMF shielding layer 121 to form an EMF shielding enclosure 126 therebetween such that EMF radiation from the mobile telephone device 119 does not escape or is at least substantially attenuated therefrom.

In alternative embodiments, certain drawer

EMF shielding layers

122 and 125 may be located externally. For example, side EMF shield layer 123 can be adhered to the outer surface of side wall 106 of drawer 103. Similarly, the rear EMF shield 122 may be adhered to the outer surface of the rear wall 107 of the drawer 103. Similarly, bottom EMF shielding layer 124 may be adhered to the bottom surface of bottom panel 108 of drawer 103.

In alternative embodiments, the side EMF shield layer 123, the back EMF shield layer 122, and/or the bottom EMF shield layer 124 may be applied to the inner surface of the chassis 101. Thus, when the front EMF shield layer 125 (applied to the front wall 105 of the drawer 103) is moved into the chassis 101, the side EMF shield layer 123, the back EMF shield layer 122, and/or the bottom EMF shield layer 124 cooperate together to form the EMF shield enclosure 126.

As shown in fig. 6 and 7, the power line 118 may be bypassed from the gap between the top of the back wall 107 and the top plate 104 or top EMF shield layer 121. As shown in fig. 7, the top EMF shield layer 121 may further extend behind the rear wall 107 of the drawer 103 to shield the gap above the rear wall 107 from EMF radiation. Similarly, the front edge of the top EMF shield layer 121 may extend to or through the front wall 105 of the drawer to cooperate with the front EMF shield layer 125 to prevent EMF radiation from escaping from the gap therebetween.
