Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tap used for the purpose of increasing the number of plug sockets in a wall outlet.

Conventional taps had a plug blade receptacle on the front side, so the height of the tap was large because it was necessary to have enough insertion space for the plug blade on the plug side. When inserted into a wall outlet, the protrusion from the outlet surface becomes large, which may result in incomplete insertion when inserting the tap blade into the wall outlet socket, and it is relatively heavy. When a plug with a captire cord is inserted into this tap, there is a problem in that the tap may come off due to the weight of the cord.

The present invention has been provided in view of the above-mentioned points, and has a plug blade protruding from the back and plug blade receptacles protruding only from the left and right sides and the bottom surface, thereby flattening the container body and allowing it to be connected to a wall outlet, etc. This makes it possible to keep the protrusion length low when inserted, and at this time, the blank surface of the container body (cover surface) can be used as a night light projection surface, making effective use of the blank space and improving product value. In addition, the neon lamp for the night light can be turned on and off by a switch, so that the neon lamp can be turned off when not in use to achieve the effect of saving electricity. The purpose is to provide a tap that can simplify the structure and improve operability by sharing the switch handle for operation, and can improve its function as a night lamp by expanding the light projection surface. .

An embodiment of the present invention will be described in detail below with reference to the drawings.

The proximal ends of the blades 3, 3 are integrally fixed by dowel tightening or rivet tightening. In this way, the first and second blade receiving spring blocks 19 and 20, on which the plug blades 3 and 3 are respectively fixed, are separated and insulated from each other by the ribs 22 on the inner surface of the flat base 1, and are placed on the flat base 1. After this, the cover 2 is placed on the flat base 1 and the cover 2, and the flat base 1 and the cover 2 are connected and fixed by driving rivets or screws 23. A large notch 6 having a sufficiently large area compared to the surface area of the cover 2 is formed in the surface of the cover 2 at approximately the center thereof, and one side of the lamp cover 7 is formed on one side of the large notch 6. Pivots 24 protruding from both sides are pivotally supported, and a lamp cover 7 is movably attached to the large notch 6 so as to substantially close it. The lamp cover 7 is made of a transparent or semitransparent thermosetting synthetic resin material, and has a lens effect that diffuses the light from the neon lamp 5 disposed behind the lamp cover 7. As is clear, the lamp cover 7 constitutes a light projecting portion of the neon lamp 5 provided as a night lamp. Further, the lamp cover 7 is rotated and urged in the upward direction by the push-up spring 25, and the projections 8, 8 protruding from both sides of the other side of the lamp cover 7 are engaged with the lower surface of the other side edge of the large notch 6, so that the lamp cover 7 is rotated in the upward direction. cover 7
A tongue-like operating section 9 is integrally extended rearward from the center of the other side of the lamp cover 7, and a protruding engagement section 11 is provided on the outer surface of the operating section 9.
is installed protrudingly. As described above, the neon lamp 5 is arranged behind the lamp cover 7, and one lead wire 5a of the neon lamp 5 is connected to the terminal 26 of one blade holder spring block 19 by wrapping or soldering. At the same time, the other lead wire 5b is connected to the movable spring plate 28 via the current limiting resistor 27.
The movable spring plate 28 is connected by soldering or wrapping to the terminal portion 29 of the movable spring plate 28, and the tip of the movable spring plate 28 is arranged opposite to a part of the edge of the fixed terminal plate 30 formed on the other blade receiving spring block 20 side. This fixed terminal board 3

A blinking switch 10 is configured. Thus, in this switch 10, when the lamp cover 7 is pushed down with a finger or the like against the spring force of the push-up spring 25, the movable spring plate 28 is moved at the tip of the operation part 9 of the lamp cover 7.
is pressed and its tip contacts a part of the edge of the fixed terminal board 30 to close the lamp cover 7. Therefore, the lamp cover 7 is used together with the light projection window of the neon lamp 5 to blink the neon lamp 5. It will have the function of a switch handle. Next, a description will be given of the holding means for releasably holding the lamp cover 7, which also serves as the switch handle, in the pushed-in position. In this embodiment, the holding means is a substantially L-shaped engagement portion having a protrusion-like engagement portion 11 on the surface of the working portion 9 and a notch-like engagement receiving portion 12 with which this engagement portion 11 engages. The engaging piece 13 is made of a plate material having spring properties, and its base end is fixed to the upper surface of the flat base 1 with a screw 31. Character-shaped portion 32
A knob body 33 is installed in the hole 6, and by pushing the knob body 33 in the opposite direction to the lamp cover 7, the engaging piece 13 engages with the small notch 38 in the center of the other side edge of the large notch 6.
The engagement piece 13 is tilted by sliding therein, and the engagement between the engagement part 11 and the engagement receiving part 12 is thereby released, and the lamp cover 7 is pushed up against the protrusion 8 by the spring force of the push-up spring 25. , 8 are returned and rotated until they engage with the lower surface of the other side edge of the large notch 6. However, the holding means of this embodiment is such that when the lamp cover 7 is pushed in and the switch 10 is closed using the operating part 9, the engaging part 1
1 and the engagement receiving part 12 are engaged, the lamp cover 7 is held in the pushed state, that is, the neon lamp 5 is kept in the lit state by turning on the switch 10, and the knob body 33 is pushed in the opposite direction to the lamp cover 7. As a result, the engagement piece 13 is tilted to release the engagement between the engagement portion 11 and the engagement receiving portion 12, and the lamp cover 7 automatically returns to the non-pushed position.

5 to 10 show a second embodiment of the present invention in which the structure of the holding means is different, and this embodiment has a cam portion formed on the operating portion 9 on the lamp cover 7 side as shown in FIG. 16, and a projecting piece 17 configured as the tip of the cam sliding spring 34 installed on the side of the vessel A.
It is composed of. The cam portion 16 is formed by cutting a groove 14 into a heart shape as shown in the figure, and the groove 14 starts at the left side of the center of the lower end in FIG. The groove 14 is formed so that it slides in the circumferential direction and ends at the right side of the center part of the lower end, and the groove 14 becomes gradually shallower from the start end to the end, so that there is a step 15 between the end and the start end. This step 15 prevents the projecting piece 17 from rotating and sliding in the opposite direction.
As described above, the protruding piece 17 is configured as the tip of the cam sliding spring 34, and the spring force of this spring causes the proximal end surface of the protruding piece 17 to press and slide into contact with the bottom surface of the groove 14 of the cam portion 16. However, when the lamp cover 7 is pushed in now, the protruding piece 17 rotates and slides in the groove 14 of the cam part 16 clockwise in the figure from the starting end, and the 9th protrusion piece 17 moves to the middle position of the groove 14 corresponding to the heart-shaped top recess. As shown in the figure, the protruding piece 17 is locked, and the lamp cover 7 is held in the pushed-in position, that is, in the position where the switch 10 is turned on. After this, release the above hold and switch 10.
To turn off the neon lamp 5, once the lamp cover 7 is further pushed in, the spring force of the cam sliding spring 34 applied to the protrusion 17 causes the protrusion 17 to move slightly clockwise within the groove 14. When the protruding piece 17 is rotated in the direction shown in FIG. When the lamp cover 7 moves and reaches the end of the groove 14, it falls down at a step 15 and moves to the starting end, and at this time the lamp cover 7 has returned to the return position as shown in FIG.

11 to 16 show a third embodiment of the present invention in which the holding means is constituted by a cam block 18 disposed on the side of the container A and a protrusion 17 at the tip of a cam spring 35 attached on the side of the lamp cover 7. This shows that.
In this embodiment, the cam block 18 has a heart-shaped groove 14 on the side surface of its lamp cover, similar to the cam portion 16 of the second embodiment, and a step 15 between its end and start end. , this cam block 18 is fixed in a recess 37 on the flat base 1. The base end of the cam spring 35 is thermally fixed to the surface of the operating portion 9, and the protrusion 17 at the free end of the cam spring 35 slides and rotates clockwise in the figure within the groove 14. Compared to the second embodiment, the same operation and effect can be obtained except that the on and off positions of the switch 10 are opposite to the operation of the lamp cover 7. In this third embodiment, the projection 8 is provided protruding from the center of the other side of the lamp cover 7. Further, 36 in the figure is a rib for holding down the cam block 18.

The present invention is constructed as described above, and the blade receptacles are formed on the lower surface and left and right sides of the vessel.
The shape of the container body can be made flat, and when the plug blade protruding from the back of the container is inserted into a wall outlet, etc., the amount of protrusion from the outlet surface is reduced, preventing incomplete insertion or omission of the plug blade. It has the effect of not coming off, and since the surface of the cover is used as a light emitting part and a neon lamp for a night lamp is placed behind it, the blank surface of the vessel can be effectively used to create a night lamp. In addition, since the lamp cover was placed in the large hole in the cover, the lamp cover became the illumination part of the neon lamp and produced a good illumination effect. In addition, since this lamp cover is also used as a switch handle, the area of the illumination part can be increased to obtain good lighting efficiency, and the switch handle can be enlarged to improve operability. Since the switch is operated by the switch handle and a holding means is provided to releasably hold the switch handle in the push-in position, the neon lamp can be turned on only at the time when the required night lamp is needed. This has the effect of providing a power saving function.
