Description

[Detailed description of the invention] This invention relates to a ceiling-suspended power outlet that can be pulled down and held at any position when used indoors, and that can be pulled up close to the ceiling when not needed. This relates to a ceiling-suspended power outlet that can be fixed to a wall when used below.

=Generally, in order to extract power from a ceiling outlet installed in the ceiling to an electrical appliance used below in the room, one end of the power cord is electrically connected to the ceiling outlet, and the other end is connected to a power strip that is fixed to the wall, for example. 62, and power was supplied from this power strip 62.

By the way, in order to fix the table tap 62 to the wall,
As shown in FIG. 1, this is accomplished by fixing a wall fixing back plate 63 to the back surface of the table tap 62 with screws 64, and inserting wood screws or the like into fixing holes 65 provided in the back plate 63.

However, this fixing method requires a special back plate 63, which has the disadvantage of increasing costs.

On the other hand, there is also a device that attaches double-sided tape to the back of the table tap 62 and fixes it to a wall surface, but with this method, when it is not fixed to the wall surface, dust collects on the double-sided tape, damaging the appearance. was there.

In view of the above-mentioned points, the present invention not only allows power to be taken out from a ceiling outlet to a lower part of the room without using a power strip, but also allows it to be fixed to a wall surface without using any special fixing means during use. The purpose is to provide a ceiling-suspended power outlet that allows for

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

The ceiling-suspended power outlet according to the present invention includes a rosette 1 fixed to the ceiling surface, a socket block 3 suspended from the ceiling by a wire 2 having one end fixed to the rosette 1, and one end of which is attached to the socket block 3. The power cord is electrically connected to a plug-in socket 4 provided on the ceiling, and the other end is connected to a ceiling outlet 5 provided on the ceiling surface through a rosette 1. It consists of a spiral cord 6 that can be expanded and contracted in any direction, and when the socket block 3 is pulled downward, the wire 2 is extended and the socket flock 3 is lowered by a lowering means, and when the tensile force is removed, the socket block 3 is stopped. a stopping means operated from the outside of the socket block 3 to release the stopping means, winding up the wire 2, and raising the socket block 3; and a wall surface transparently provided on one side of a part of the socket block 3. It is characterized by being composed of a fixing hook hole 60 and an insulating inner cover 61 attached to the inside of the hook hole 60, and each part will be explained in more detail below.

As shown in FIGS. 3 to 5, the socket block 3 is inserted into a housing formed by a body 20 and a cover 21, and includes a socket 4, a take-up rule 7 constituting a lowering means, and a take-up.
It is constructed by assembling a stopper spring 8 which is used as means for stopping the rotation of the winding wheel 10, and a camshaft 9 which acts as a releasing means to release the stoppage of the winding wheel 7 caused by the stopper spring 8 and to raise the socket block 3.

The winding wheel 7 has a rotary shaft 22 protruding from the center of one side on the inner surface of the body 20, and a cylindrical shaft 25 protruding from the center of the other side from the cover 2.
1 inner surface, and are rotatably mounted inside the socket block 3 by fitting them respectively.

The lower end of the wire 2 is connected to an upper drum 21 protruding from the periphery of the upper surface of the winding wheel 7, and is wound around the upper drum 27 so as to be unwound.

On the other hand, this winding wheel 7 is connected to the upper drum 2 by means of all warts 31 housed in the lower drum 30 protruding from the periphery of the lower surface.
It is rotationally biased in the direction of winding the wire 2 around the outer periphery.

Further, a plurality of locking recesses 35 are formed at approximately equal intervals along the circumferential direction on the outer periphery of the lower drum 30, and a stopper spring 8 with one end attached to the bottom surface of the body 20 is attached to the lower drum 30 including each locking recess 35. The take-up reel 7 is in elastic contact with the outer peripheral surface of the wire 2.
When rotating in the direction of unraveling, that is, the fully flexible spring 31
When rotating against the spring force, the take-up reel 1 rotates without the stopper spring 8 being locked in each recess 35.
When the take-up reel 7 rotates in the direction in which the wire 2 is wound, that is, when it rotates by the spring force of the spring 31, the tip of the stopper spring 8 fits into the recess 35, and the take-up reel I stop the rotation.

That is, in use, when holding the socket block 3 and pulling it downward, the take-up wheel 7 rotates freely and the wire 2 is unraveled from the take-up rule 7, removing the pulling force on the socket block 3. If excluded, all 1 spring 31
The take-up reel 7 rotates in the direction to wind up the wire 2 until the stopper spring 8 locks in the locking recess 35 at the nearest position, and then stops at the position where the stopper spring 8 fits into the locking recess 35. As a result, the socket block 3 is held at a position where it is lowered by an arbitrary length from the ceiling.

The camshaft 9, which is a means for releasing the stoppage of the winding wheel 7, is inserted into a boss cylinder 40 protruding from the inner surface of the cover 21 and connected to a push button 41 whose rear end is exposed to the outer surface of the cover 21. The cover 21 is biased outward by a coil spring 42.

The tip of the camshaft 9 is fitted into a hook 44 extending to the center of the stopper spring 8, and when the camshaft 9 is pushed inward against the spring force of the coil spring 42, the tip of the camshaft 9 The stopper spring 8 is pushed open so as to disengage from the take-up reel 7, and the take-up reel 7 is rotated by the spring force of the all spring 31 in a direction to wind the wire 2 around its outer periphery.

That is, when the push button 41 exposed on the outer surface of the cover 21 is pushed in, the stop of the take-up reel 7 is released, and the wire 2, which has been pulled out from the socket block 3 for a predetermined length, is wound onto the take-up reel I. As a result, the socket block 3 rises to a position 1 near the ceiling.

Hook hole 6 transparently provided in socket block 30 cover 21
0 is a so-called single hole because it is locked to a hook or wood screw provided on the wall surface.

As shown in FIG. 6, a reinforcing lip 66 is provided around the inside of this hooking hole 60, and a portion of the reinforcing rib 66 extends upward to serve as a lip 67 for preventing deflection of the stopper spring 8. .

As shown in FIG. 7, this deflection prevention rift 67 makes elastic contact with the outer periphery of the hook piece 44 of the stopper spring 8, and when the camshaft 9 is inserted, guides the stopper spring 8 to be pushed open to prevent deflection. It is something.

Further, the hooking hole 60 is located approximately at the center of a square frame-shaped projecting lip 68 protruding from the inner surface of the cover 21, and the projecting rib 68
A plurality of heat bonding and fixing lips 69 are provided protruding from the upper end of 8 .

Rectangular insulating inner cover 61 made of polyvinyl chloride plate
Notches 70 corresponding to the lips 69 are provided on the four circumferences of the inner cover 61, and through holes 71 corresponding to the deflection prevention ribs 67 are provided at key points of the inner cover 61.

After the inner cover 61 is placed over the upper end of the projecting rib 68 so that the heat-adhesive fixing lip 69 is located in the notch 70 and the deflection prevention lip 67 passes through the through hole 11, the heat-adhesive fixing lip 69 is placed in the notch 70. The inner cover 61 is attached to the inside of the hook hole 60 by thermally bonding the inner cover 69.

Incidentally, conventionally, the cover 21 and the body 20 were fitted together by fitting the locking piece 50 into the fitting groove 51 and the lip 52 into the notch 58, respectively, as shown in FIG.

However, in such a fitting method, the above-mentioned cover 2
1 has a drawback in that when an external force is applied in the direction shown by the arrow in FIG.

Therefore, in the present application, the locking piece 50 is inserted into the fitting groove 5 as shown in FIG.
1, and a protruding lip 54 provided at the opening edge of the body 20 is fitted into a groove 55 provided at the opening edge of the cover 21, thereby fitting the body 20 and the cover 21 together.

With this structure, even if an external force is applied to the cover 21 in the direction of the arrow, it will not come off easily due to the engagement between the protruding rib 54 and the groove 55, and even if an external force is applied in the direction of the arrow C, the locking piece 50 will not come off. It is difficult to come off due to the engagement with the fitting groove 51, and the fitting strength can be improved compared to the conventional case.

Further, since the notch 56 is provided along the outer periphery of the opening edge of the body 20, warpage and gaps between the body 20 and the cover 21 are difficult to stand on their own.

Furthermore, the protruding ribs 54 also prevent dirt from entering.

To use the ceiling-suspended power outlet configured as described above, hold the socket block 3 and pull it downward.
After stopping at an arbitrary height, the head of the hook provided on the indoor wall is inserted into the hooking hole 60, and the head of the hook is positioned in the space between the inner surface of the cover 21 and the inner cover 61. This fixes the socket block 3 to the wall surface.

This prevents the socket block 3 from being swung by an external force at the suspended portion 11 and colliding with and damaging nearby instruments or display cases.

One of the great things about this invention is that it is configured as a ceiling-suspended power outlet as described above, so you can connect the power supply at any height from the ceiling to the lower part of the room without using a power strip like in the past. The socket block can be taken out, and one side of the socket block has a transparent hook hole for hook locking, and an insulating inner cover is attached to the inner surface of the hook hole, leaving a space for the hook head. When the socket block is pulled down and used, the head of the hook provided on the indoor wall is inserted into the hook hole, and the head of the hook is positioned in the space provided inside the handle hole. (The socket block can be fixed to the indoor wall, and the socket block will not swing and damage nearby equipment or display cases, or hit people's heads.) The inner cover prevents foreign objects and dirt from entering the socket flock, and the inner cover can also be used to adjust the insertion distance of the hook, preventing the hook from touching the internal live part even if the hook is inserted too far. There is no such thing.
