Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ceiling-suspended electrical outlet, and more specifically, to a socket block that is suspended from the ceiling in order to utilize a power outlet installed in the ceiling in a lower part of the room for electrical appliances used indoors. This invention relates to a ceiling-suspended outlet that holds a load power cord and prevents tension on the load power cord.

Conventionally, as shown in FIG. 1, this type of ceiling-suspended outlet is connected to the lower surface of the socket block 5 by a holding means 10 at the lower end of a cord support 9 fixed to one surface of the socket block 5. However, since various power plugs are connected to the socket block 5, the holding means 10 can always hold the load power cord 8. As such, the holding means 10 must be positioned sufficiently away from the lower end of the socket block 5, and for this reason, the cord support 9 must protrude further downward than the socket block 5. However, when the cord support protrudes significantly downward in this way, there is a problem that when the power plug T is not connected to the socket head knob 5, the cord support protrudes downward unsightly and becomes a hindrance. The present invention has been made in view of the above points, and its main purpose is to enable the cord support that projects downward from the socket block to be retracted into one side of the socket head nook when not in use. To provide a ceiling-suspended electrical outlet in which a cord support does not unsightly protrude downward when not in use.

The present invention will be described in detail below based on embodiments shown in the figures.

As shown in FIG. 2 and below, the ceiling-suspended outlet according to the present invention has a relay power cord 3 whose upper end is connected to a ceiling outlet 2 disposed on the ceiling 1 and a socket 4 disposed at the lower end of the power cord 3 that hangs down from the ceiling 1. A load power cord 8 extending from a power plug T inserted into a socket block 5 with a built-in socket block 5 and a socket 4 having a plug blade receiving groove 6 opened on the bottom surface of the socket block 5 is held at a location near the power plug T. Cord support body 9 that supports this on the socket head nozzle 5
5, the cord support 9 overlaps one surface of the socket block 5, and the lower end of the cord support 9 is placed at a position where it approximately coincides with the lower end of the socket block 5, and the lower end of the cord support 9 is positioned far below the lower end of the socket block 5. The socket block 5 can be moved vertically between the protruding position and the
The present embodiment is characterized in that a holding means 10 is provided at the lower end of the cord support 9 for detachably holding a portion of the load power cord 8 near the power plug 7. , shows an example in which the cord support 9 is connected to the socket block 5 using an assembly screw 11 that connects the body 5a and cover 5b that constitute the socket block 5. As shown in the figure, the relay power cord 3 is a spiral cord that can be expanded and contracted in the vertical direction.A relay power plug 12 is attached to the upper end, and the lower end is connected to the socket 4 within the socket block 5. , the relay power plug 12 is housed in the rosette 13. This rosette 13 is fixed to the ceiling 1 with a mounting screw 14, and the socket block 5 is suspended and supported by a wire 15 whose upper end is fixed to the rosette 13. The lower end of the wire 15 is wound around and connected to a take-up reel 16 built into the socket block 5. The take-up reel 16 is urged to rotate by a spring force in the direction in which the wire 15 is wound around its outer periphery, and is also provided with a stopping means (not shown).
When the push button 17 exposed on the outer surface of the socket block 5 is pressed, this stopping means is released and the wire 15 is wound on the take-up reel 16, causing the socket block 5 to be stopped at any rotational position. moves upward and when the socket protester 5 is pulled down, the stopping means stops the take-up reel 16 with the wire 15 unraveled to a predetermined length, and the socket proc 5 is placed in a predetermined position. Hold. As shown in FIG. 3, the socket 4 at the lower end of the relay power cord 3 is fixed in the socket block 5 with its blade receiving groove 6 opened at the bottom surface of the socket block 5, and is used for electrical appliances used indoors below the ceiling 1. The power plug 7 of the load power cord 8 that extends further is connected to the socket 4 by inserting its blade 18 into the blade receiving groove 6. In the illustrated embodiment, the fourth socket 4 is
As shown in the figure, a type to which a power plug 7 with a ground terminal 19, which is mainly used in hospitals and the like, is connected is shown. As shown in FIG. 6, the cord support 9 is formed into a shape in which a support piece 21 extends perpendicularly from the lower end of a flat main body plate 20, and has a long length running vertically in the center of the width direction of the main body plate 20. A hole 22 is provided, and the assembly screw 11 for connecting the body 5a and the cover 5b constituting the socket block 5 is accommodated in the elongated hole 22, whereby the cord support 9 is connected to the socket block 5 in a vertically movable manner. A locking hole 23 is formed at both the upper and lower ends of the elongated hole 22, and locks into the neck of the assembly screw 11, respectively, so that when the cord support 9 is fully pulled out downward, as shown in FIG. The assembly screw 11 is locked in the locking hole 23, and when the cord support 9 is pulled upward as shown by the imaginary line in the figure, the assembly screw 11 is locked in the locking hole 23 at the lower end, so that the cord The support body 9 is held in two positions, upper and lower, without wobbling up and down. Further, the cord support body 9 has each locking hole 23
At the position where the assembly screw 11 is inserted, the socket block 5 can be rotated vertically around one side of the socket block 5 using the assembly screw 11 as a fulcrum. As shown in FIG. 6, a pair of U-shaped receivers 24 are formed on the support piece 21 at the lower end of the cord support 9, corresponding to one socket 4, and a tongue piece 25 is inserted into each U-shaped receiver 24. holding means 1 for supporting a load power cord 8 connected to the socket 4 on the socket block 5;
Configure 0. As shown in FIG. 8, the tongue piece 25 is formed into a small piece having a shaft 26 at one end and teeth 27 at the other end, and by fitting the shaft 26 into the bearing 28 at the base of the U-shaped receiver 24. , as shown by solid lines and imaginary lines in FIG.
By fitting into the mounting hole 30 provided in the support piece 21
It is further prevented from falling off. As shown by the imaginary line in the figure, each tongue piece 25 usually has a pair of U
It is housed in each U-shaped receiver 24 so as to close the space between the U-shaped receivers 24, and when the load power cord 8 is passed between both tongue pieces 25, each tongue piece 25 is set at a predetermined angle as shown by the solid line in the figure. The teeth 27 of each tongue piece 25 bite into the insulating layer of the load power cord 8, thereby holding the load power cord 8 on the cord support 9, that is, the socket block 5, and preventing tension on the cord. be done. Note that the tongue piece 25 has a concave portion 31 on the tip end surface having a shape that matches the circumference of the load power cord 8.
is formed. Since the present invention has the above-described configuration, when the load power cord of an electrical appliance used indoors is not connected to the socket block, it is necessary to hold the load power cord in the socket block to prevent tension on the cord. The cord support that protrudes downward from the socket block can be moved upward and hidden behind one side of the socket block, which prevents the cord support from protruding significantly below the socket block when not in use, causing an obstruction or an unsightly appearance. It has the advantage of not giving any
