Description

SPECIFICATION Electric power supply tracks The present invention relates to electric power supply tracks which may be installed, for example, at the bottom of a wall of a room.

A known type of electric power supply track is installed at corners of walls and floors to provide a power supply and to enable telephone wires and/or TV cables to be installed therein and taken away therefrom. One example of the known type of electric power supply track is shown in Figures 1 and 2 of the accompanying drawings. Figure lisa perspective view and Figure 2 is a side view of an electric power supply track 1, which is moulded from plastics material in such a manner as to provide spaces 'a' and 'b' shaped like a capital C in crosssection transverse to a substrate or base 6 thereof. A pair of parallel electric supply conductors 5 are disposed by moulding in respective grooves 4, the openings of which face each other.The grooves 4 are formed in a top plate 2 and a bottom plate 3, respectively, each of which projects forwardly from the substrate 6. The bottom space 'b' serves to encase therein wires such as TV feeders and telephone lines. The electric power supply track 1 further comprises plural protrusions 7 which project rearwardly from the substrate 6 and abut a wall 8. Afoot 9 is formed under the space 'b' and abuts a floor 11.

A plurality of plug sockets 10 can be attached to the electric power supply track 1 in front of the space 'a' at any desired places for the purposes of connecting the electric power supply from the pair of parallel conductors 5 to plugs such as 13. The electric power supply track 1 is fixed to the wall 8 by screws 12 extending through the substrate 6. A cover plate (not shown) is mounted on the supply track 1 after installation of the supply track 1 to the wall 8 in order to cover the space 'a' at places where plug sockets 10 are not situated.

The above-described electric power supply track 1 suffers from the following disadvantages. The structural strength of the electric power supply track 1 is not sufficient whereby the shape of the space 'a' might be deformed if an external force is applied to the top plate 2 during use, for example if someone treads on the top plate 2. Once the shape of the space 'a' is deformed, the distance between the parallel conductors 5 might be changed locally and/or contact segments of plug sockets 10 abutting the parallel conductors 5 may be permanently deformed thereby obstructing normal power supply and/or causing possibly heating at the contact segments.

According to the present invention there is provided an electric power supply track made of moulded plastics and comprising: a substrate; a top partition member, a central partition member and a bottom plate formed on the substrate, the top partition member, the substrate and the central partition member defining a first space, and the central partition member, the substrate and the bottom plate defining a second space which is disposed below said first space; and a pair of conductors disposed parallel to and facing each other, the conductors being disposed on a lower face of the top partition member and on an upper face of the central partition member, respectively, in said first space; wherein a sloping top plate is provided above the top partition member with a buffer space therebetween.

An electric power supply track embodying the invention and described hereinbelow is of a structurn which is resistant to deformation by external forces, thereby ensuring a stable power supply for a long period.

The invention will now be further described, by way of illustrative and non-limiting example, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a known electric power supply track in use; Figure 2 is a side view of the track of Figure 1; Figure 3 is a perspective view of an electric power supply track embodying the present invention in use; Figure 4 is a side view of the track of Figure 3; Figure 5 is a perspective view of an end portion of the electric power supply track embodying the present invention in use; Figure 6 is a perspective view showing the other end portion of the power supply track of Figure 5 in use; and Figures 7(a) and 7(b) are side views of other electric power supply tracks embodying the present invention.

An electric power supply track embodying the present invention will now be described with reference to Figures 3 and 4. Figure 3 is a perspective view of the electric power supply track and Figure 4 is a side view of the track. A track body 20 comprises a first space 26 provided with a pair of parallel conductors 22 and 22' for electric power supply therefrom, and a second space 28 for encasing or housing other wires. The first space 26 is formed on an upper part of a substrate 19 of the track body 20, which is made of plastics, and the second space 28 is formed on a lower part of the substrate 19. The first space 26 is defined by a top partition member 23, a bottom partition member 23', the substrate 19, a top front plate 21a, and a central front plate 21b. The first space 26 has an oblong opening 21 in a lengthwise direction at the front thereof.The parallel conductors 22 and 22' are disposed by moulding on faces of the top and central partition members 23 and 23' in such a manner that only faces thereof which face each other and are to be used for contacting contact segments of a plug socket are exposed in the first space 26.

The top partition member 23 is provided with a sloping top plate 24 above the top portion of the substrate 19 with a preferably closed buffer space 25 therebetween. An additional partition member 23" is provided under the central partition member 23', thereby forming a buffer space 125' between the members 23' and 23". Accordingly, the track body 20 has a structure which is more resistant to deformation by an external force than a conventional struc ture without such buffer spaces. The surface of the sloping top plate 24 is planar in the example shown in Figures 3 and 4. However, it is also practicable to shape the front top surface of the sloping top plate 24 to constitute a curved surface which slopes down towards the front.

The second space 28 is shaped like a capital C in cross section, and has an opening 27 in a lengthwise direction at the front thereof. The second space 28 is used for housing one or more of several kinds of wires, e.g. telephone lines, TV feeders, intercom wires, etc.

The first space 26 of the track body 20 is used for establishing electrical contact between the parallel conductors 22 and 22' and contact segments 30 and 30' of a plug socket 29. This is possible because the contact segments 30 and 30' are made of an elastic metal and project outwardly at upper and lower sides, respectively, of the rear of the socket 29.

Accordingly, when a plug 31 is plugged into the socket 29 by movement as indicated by an arrow P in Figure 4, the electric power supply is connected from the parallel conductors 22 and 22' to the plug 31.

To mount the socket 29 in the opening 21,the contact segments 30 and 30' are firstly inserted into the opening 21 in such a position that they line up parallel to the parallel conductors 22 and 22'. The socket 29 is of such a size that the distance from the centre of the contact segments 30 and 30' to the top side of the socket 29 in the mounting position is greater than the distance from the same centre to the bottom side thereof. Then, by rotating the socket 29 through 90" the contact segments 30 and 30' are connected to the parallel conductors 22 and 22', respectively.Since a protrusion 32 is provided on the bottom front plate 21 b, when the contact segments 30 and 30' of the socket 29 are inserted in the opening 26 upon mounting of the socket 29 it is necessary to hold the socket 29 in such a manner that the shorter length side is below the longer length side. A column part 29' of short length is formed on the rear side of the socket 29 in order to avoid abutment of corner parts of the socket 29 against the protrusion 32 when the socket 29 is rotated by 90" upon mounting.

If the contact segments 30 and 30' are inserted in the opening 21 with the socket 29 held upside down, rotation of the socket 29 would then be prohibited due to abutment of the longer length side against the protrusion 32. Thus, electrical contact is always made in such a manner that the conductor 22 (or 22') of one polarity is connected to the contact segment 30 (or 30').

The track further comprises a top cover 33 and a bottom cover 34. The top cover 33 is used to cover the opening 21 of the first space 26, except at the place where the socket 29 is mounted, as shown in Figure 3. The bottom cover 34 is used to cover the opening 27 of the second space 28. Thus, entry of foreign matter such as dust or insects can be prevented.

A brief description of the manner of installing the track body 20 on a wall 8 will now be given. After positioning the substrate 19 on the wall 8, the track body 20 is fixed to the wall by means of screws 35, as shown in Figures 3 and 4. A box 37 buried in the wall is used to connect the parallel conductors 22 and 22' in the first space 26 to a mains power supply, as shown in Figure 5. Lead-in wires 38 which run through a conduit 36 buried in the wall are connected to the parallel conductors 22 and 22' through a connector 39 inside the box 37.

An end cap 40 is used to close the other end of the track body 20, as shown in Figure 6. A side face of the cap 40 is the same shape as the cross-sectional shape of the track body 20. The end cap 40 is provided with stopper means 41 which can be inserted into the first space 26 or the second space 28 thereby supporting the end cap 40 at the end of the track body 20.

The electric power supply track of Figures 3 to 6 has the following advantageous features. Since the track body 20 is provided with the first buffer space 25 and the second buffer space 25' on the top and bottom sides of the first space 26, an external force impressed on the top part of the track body 20 is effectively buffered and thus the force is not applied directly to the top partition member 23. Therefore, the track body 20 is not easily deformed and thus the distance between the parallel conductors 22 and 22' is not easily varied. There is no little or no fear that the contact segments 30,30' of the socket 29 will be deformed. Accordingly, a stable electric power supply is ensured during use of the electric power supply track, even if the socket 29 is later mounted at another place.

In addition, since the track body 20 is further provided with the sloping top plate 24 having a plain or curved surface, anyone stepping by accident on the track body 20 after installation will soon slip off, due to the sloped top plate 24. Thus, there is little or no fear of the track body 20 being crushed under the offending foot.

Moreover, the track body 20 is provided with a sloping rear face 28' at the bottom of the substrate 19. Therefore, even if the corner of the wall and floor is round or uneven due to the existence of foreign matter, no problem arises in placing the track body 20 in the corner.

Further, since the bottom part of the socket 29 abuts againstthe protrusion 32, if anyone accidentally steps on the socket 29 after its installation, for example during moving furniture, the protrusion 32 can sustain the load thereby preventing the socket 29 falling out of the first space 26.

Figures 7(a) and 7(b) are side views of further electric power supply tracks embodying the present invention and having structures similar to those of the supply tracks shown in Figures 4 and 2, respectively. Parts identified by the same numerals correspond to parts of the electric power supply tracks shown in Figures 4 and 2. The supply tracks of these embodiments comprise the further feature that a metal plate 111 having two bent parts 112a and 112b is buried in the substrate 19 (or 6) when the track body 20 (or 1) is moulded. The metal plate 111 is buried to extend in the lengthwise direction of the first space 26 (or 'a'). The two bent parts 11 2a and 11 2b are respectively buried in the top partition member 23 (or 2) and the central partition member 23' (or 3).

The electric power supply tracks of Figures 7(a) and 7(b) have structures as strong as or stronger than those of the power supply tracks of Figures 3 to 6. Hitherto, there has been the problem that the substrate 19 (or 6) is liable to be bent between its fixing places when it is fixed on the wall by the screws 35 (or 12) and thus that the distance between the parallel conductors 22 and 225 (or 5 and 5') is liable to vary. The electric power supply tracks described above are at least largely free from such deformation problem. In addition, dust is not likely to become electrostatically attached to the supply track since it is discharged through the metal plate 111 and the screws 35 (or 12).
