TECHNICAL FIELD

The present invention relates generally to an extension multiple socket outlets device, and particularly to an inverted T-shape multiple socket outlets device, convertible to an extension multiple socket outlets device.

BACKGROUND

Extension multiple socket outlets devices are well known electrical devices, which allow more than one socket outlet to be used at a distance from a previously designated point in the wiring circuit. There are many ways of concealing the extension chords when they are not in use. When in use, these concealed extension chords are retracted and extended from their concealment.

In an earlier Malaysian patent application, the applicant has disclosed an embodiment of an inverted T-shape multiple socket outlets device. This embodiment does not have any extension chord facility. It provides a facility of multiple socket outlets device locally at the one previously designated point in the electricity distribution circuit. Because of its integral design, the specific embodiment achieves certain advantages.

A multiple socket outlets device according to the preamble of claim 1 is disclosed in EP-A1-0 802 585 .

SUMMARY OF THE INVENTION

It is therefore the primary object of the present invention to offer a multiple socket outlets device which can be used at one point in the electricity distribution circuit, as well as at a distance from that point.

According to the invention, a multiple socket outlets device comprises an electrical plug, an extension cable, and a casing integrally and electrically fitted with multiple socket outlets displayed on one face, wherein the electrical plug is removably attached to the top wall of the casing thus forming an inverted T-shape multiple socket outlets device and the extension cable is neatly tugged away in a concealed compartment in the casing.

Preferably, an elongated opening is provided on the top wall. Preferably, an adapter means is fitted to the base of the electrical plug, such that the adapter means is first passed through the elongated opening. The adapter means then engages the top wall of the casing when the adapter means and the plug are rotated at right angle with the length-wise direction of the elongated opening. An inverted T-shape multiple socket outlets device is then formed. Because of the space in the elongated opening, the electrical plug is able to adjustably move relative to the casing, in order to accommodate and engage flush and non-flush panel sockets on a wall.

DETAILED DESCRIPTION

In prior art extension multiple socket outlets devices, an electrical plug is connected to a circuitry inside a casing equipped with multiple socket outlets. The plug can either be 3-pin or 2-pin. The technology is well known. For the sake of simplicity, the details of this technology will not be discussed. The following description will concentrate on how an inverted T-shape multiple socket outlets device is formed and how it is converted to an extension multiple socket outlets device.

Essentially, the important components making up the invention are a rectangular casing (3) with a concealed compartment (32), an extension cable (5) and an electrical plug (2) fitted with a flat adapter means (4). An elongated opening (31) is provided on the top wall of the casing (3).

Referring to Figures 1a, 1b and 1c, the invention is shown when assembled and used as an inverted T-shape multiple socket outlets device (1). On the front of the casing (3), four socket outlets are provided. The electrical plug (2) is electrically connected to the casing (3). The plug (2) is disposed on the top wall of the casing (3). The pins of the plug (2) face towards the back of the casing (3) away from the socket-bearing front face, when the plug (2) is oriented and assembled to form an inverted T-shape multiple socket outlets device (1). It is important to note that the length-wise direction of the elongated opening (31) is at right angle to the length-wise direction of the top wall. To engage the top wall of the casing (3), the flat adapter means (4) at the base of the plug (2) engages the top wall of the casing (3) and is oriented at right angle to the length-wise -direction of the elongated opening (31). To disengage from the top wall of the casing (3), the flat adapter means (4) is oriented parallel to the length-wise direction of the elongated opening (31).

Referring to Figures 2a and 2b, one end of an extension cable (5) is connected to the plug (2), and the other end of the cable (5) is connected to the electrical distribution circuitry inside the casing (3). A compartment (32) is provided in the casing (3) to conceal the extension cable (5). Mounting means (33) in the form of parallel clips are also provided, so that the cable (5) is neatly tugged away. The length of the elongated opening (31) is indicated as L1 and the width is indicated as W1. W1 is smaller than L1.

Referring to Figures 3a, 3b, 3c, 4a, 4b, and 4c, it is clearly illustrated how the plug (2) is inserted and attached to the casing (3) with the assistance of a flat adapter means (4). Essentially, the flat adapter means (4) comprises integrally a neck portion (41) and an enlarged body portion, and the adapter means (4) is fitted to the base of the plug (2). The length (L2) of the flat adapter means (4) is slightly smaller than the length (L1) of the elongated opening (31). The width (W2) of the flat adapter means (4) is smaller than the width (W1) of the elongated opening (31). These dimensions allow the adapter means (4) to "sink" into the casing (3) through the elongated opening (31). The length (T2) of the neck portion (41) is slightly greater than the thickness (T1) of the top wall of the casing (3). The length (L2) of the flat adapter means (4) is greater than the width (W1) of the elongated opening (31). When the flat adapter means (4) engages the top wall of the casing (3) and assumes a right angle orientation with the length-wise direction of the elongated opening (31), the flat adapter means (4) forms preferably an interference fit with the top wall. The assembly is thus achieved.

The elongated opening (31) on the top wall of the casing (3) provides a further advantage. As the length-wise direction of the elongated opening (31) is oriented at right angle to the length-wise direction of the top wall of the casing (3), and the plug (2) is disposed parallel to the casing (3), there is certain space within the elongated opening (31) to allow a slight transverse movement of the plug (2). Referring to Figure 5a, the invention is about to be fitted to a non-flush panel socket (6) with a thickness of more than 1 cm. Referring to Figure 5b, the invention is about to be fitted to a flush panel socket (7) with a thickness of approximately 1 cm.

According to the teaching of the invention, the device is incorporated with other electrical features including surge protection, or timer, or lightning protection.
