[Industrial applications]

 The present invention relates to an improvement of a floor outlet installed on the floor of an office or the like.

[0002]

[The purpose of the device]

 OA equipment such as office computers, word processors, facsimiles, and copiers is increasing in offices, and outlets for supplying power to these OA equipment are often installed on the floor surface in the office. Up to now, various types of floor outlets have been developed. It is known that one of them is a type that when the lid plate is pulled up, the outlet is also lifted on the floor. However, this type has a large part that protrudes above the floor surface, and it was often the case that a plug was inserted and the foot was bumped during use. Therefore, the present invention fixes the outlet to the inside of the lower case so that the outlet does not lift even if the lid plate is opened, and it is enough to open the lid plate by connecting the plug while using it. It is an object of the present invention to provide a floor outlet that allows the opening of the cover plate to be adjusted stepwise and has less risk of hitting a foot.

[0003]

[Constitution of device]

 The structure of the present invention for achieving the above-mentioned object will be described in detail. The invention according to claim 1 is an outlet in which a receiving surface of a plug is obliquely fixed inside a lower case, and the outlet is housed. A flange portion protruding from the upper peripheral edge of the fixed lower case, a lid plate that is attached to the central opening of the flange portion so as to be openable and closable, and a lid plate on the lower end of the lid plate to adjust the opening degree of the lid plate stepwise. Engaging tongues that are provided with a plurality of recesses at appropriate intervals to project, and a state in which the lid plate is closed by inserting the engaging tongues into the recesses that are recessed in the engaging tongue and the lid plate. A floor outlet comprising: a stopper attached to the flange portion for holding the opened state; and the invention according to claim 2, wherein the recessed portion is located at the uppermost portion of the engaging tongue piece. When you remove the stopper inserted inside, There Ru floor outlet der of claim 1 formed by attaching a pressing element which elastically presses the back surface near the pivot point of the cover plate so as to lift slightly automatically upwards.

According to the present invention, the opening of the cover plate can be arbitrarily adjusted. For example, when connecting the plug, the cover plate is fully opened and the plug is easily inserted into the outlet fixed in the lower case. In addition, after connecting, the opening of the lid plate can be reduced to minimize the portion protruding to the floor surface, and the opening for each step can be adjusted at appropriate intervals on the engaging tongue. It can be held by inserting a stopper into the recessed portion.

【Example】

 Hereinafter, the concrete structure of the floor outlet of the present invention will be described in detail based on the illustrated embodiment. 1 is a perspective view showing an example of a usage state of a floor outlet of the present invention, FIG. 2 is a partially cutaway plan view showing an embodiment of the floor outlet of the present invention, and FIG. 3 is a sectional view of the floor outlet shown in FIG. .

In the figure, reference numeral 1 denotes an outlet, and the outlet 1 is fixed in a lower case 2 so that a receiving surface 3 of the plug is inclined so as to be easily operated. Reference numeral 4 denotes a flange portion projecting from the upper peripheral edge of the lower case 2 accommodating and fixing the outlet 1, and the lower peripheral edge portion of the flange portion 4 is a mounting hole formed in a floor panel or the like (not shown) forming a free access floor or the like. Abut the upper peripheral edge.

Reference numeral 5 denotes a lid plate which is hinged to the central opening 6 of the flange portion 4 so as to be openable and closable, and 7 denotes a pivot of the lid plate 5. Reference numeral 8 is an engaging tongue vertically provided on the lower surface of the front end of the lid plate 5 so as to draw an arc, and 9 is a plurality of recesses provided in the engaging tongue 8 at appropriate intervals. The depth of the recess 9 is set so that the tip of a stopper described later can be inserted therein.

Reference numeral 10 denotes a stopper that is provided near the center of the front end of the flange portion 4 and that moves forward and backward. The stopper 10 is inserted into a recess 9 that is recessed in the engaging tongue piece 8 and the lid plate 5 is attached. Holds the action. As shown in FIG. 2, the stopper 10 has one end rotatably attached to the flange portion 4 by a shaft 11 and is always urged counterclockwise about the shaft 11 by a coil spring 12. Has become. When the operation button 13 is rotated clockwise from the upper surface side of the flange portion 4 against the urging force of the coil spring 12, the tip of the stopper 10 is disengaged from the recess 9 of the engaging tongue piece 8 and the cover plate is released. 5 is in a released state and can be opened and closed around the pivot 7. When the stopper 10 is inserted into the recess 9 located at the uppermost stage of the engaging tongue piece 8, the lid plate 5 is in a closed state, and the upper faces of the lid plate 5 and the flange portion 4 are substantially flush with each other. Will be formed.

In addition, reference numeral 14 in the figure denotes a presser that elastically presses the back surface of the cover plate 5 near the pivot 7 upward, and is inserted into the uppermost recess 9 of the engaging tongue 8. When the stopper 10 is released, the lid plate 5 is automatically lifted slightly upward by the elastic force of the pressing element 14. Reference numeral 15 is a coil spring for applying an upward biasing force to the pressing element 14. The pressing element 14 is arranged in a block 17 fixed to an upper mounting arm 16 that supports the outlet 1.

Next, the operation example of the floor outlet of the present invention will be described. When the plug is not connected, the front end of the stopper 10 is placed in the uppermost recess 9 formed in the engaging tongue 8. When it goes in, the upper surface of the lid plate 5 is formed to be substantially the same as the upper surface of the flange portion 4. Since the stopper 10 is inserted into the uppermost recess 9 by the biasing force of the coil spring 12, the stopper 10 is kept locked. When connecting the plug 18 to the receiving surface 3 of the outlet 1, the operation button 13 provided on the upper surface of the flange portion 4 is rotated clockwise. Then, the tip portion of the stopper 10 is separated from the recess 9 and the locked state is released, and the lid plate 5 is automatically lifted slightly upward by the spring force of the pressing element 14. In this state, the lid plate 5 can be freely opened and closed, so that the plug 18 can be easily connected to the outlet 1.

After this connecting operation, the lid plate 5 is pushed down according to the diameter of the cable 19 so that the stopper 10 is placed in the recess 9 of the engaging tongue 8 which is vertically provided on the lower surface of the tip of the lid plate 5. Insert and finish the set. In addition, FIG. 1 is for explaining the state in which the plug 18 is connected to the outlet 1. The part of the plug 18 is drawn relatively large, but in reality, most of the plug 18 fits inside the lower case 2. Therefore, the concave portion 9 of the engaging tongue piece 8 is selected and the stopper 10 is inserted into the concave portion 9 so that a gap sufficient for the cable 19 to pass through is formed between the flange portion 4 and the cover plate 5. In this way, since the stopper 10 is inserted into the recess 9 of the engaging tongue 8 even when the cover plate 5 is open, the cover plate 5 is in the locked state, and the cover plate 5 is carelessly opened. There is no such thing as lifting.

[0012]

[Effect of device]

 The floor outlet of the present invention is constructed as described above, and the opening of the lid plate can be adjusted arbitrarily. When the plug is connected, the opening of the lid plate is enlarged and fixed to the lower case. In addition to making it easier to insert the plug into the, the opening of the cover plate after connection is made smaller so that the part protruding above the floor surface is made as small as possible, and the risk of hitting the foot can be reduced. Each opening can be reliably held by selecting a plurality of recesses formed in the engaging tongue and inserting a stopper.
