Description

[Technical field]

[0001] The present invention relates to a general-purpose outlet plug and outlet plug adapter that have a mechanism that allows them to be relatively easily removed with one hand from an unfixed power outlet such as a power tap (extension cord) or from a fixed but difficult-to-remove power outlet location. [Background technology]

[0002] The main body [Fig. 1] (3) and the lid-shaped main body of the proposed outlet adapter [Fig. 5] (15) are formed by simultaneously molding the left and right slide arms (1, 1a), (14, 14a) as one unit, and the elasticity of the plastic resin is utilized to cause deformation and restoration of the slide arm parts [Fig. 3] (11), [Fig. 6] (20) to cause bending [Fig. 3] (11, 11a), [Fig. 7] (20, 20a). The pusher pin [Fig. 4] (12, 12a) [Fig. 7] (23, 23a) slides downward due to movement within the hole-shaped guide parts [Fig. 1] (2, 2b), [Fig. 5] (16, 16a), pushing out the pin in the direction of pulling out the main body. An outlet plug with this mechanism added [Figure 1] and a separate, detachable outlet plug adapter with a similar mechanism [Figure 5].

[0003] [Fig. 1][Fig. 5] In both designs, the slide arm portions (1, 1a), (14, 14a) are molded integrally with the main bodies (3), (15), respectively, minimizing the number of parts and assembly man-hours. The same applies to the two designs in which the mounting positions of the slide arms are shifted by 90 degrees as shown in [Figure 8] and [Figure 9].

[0004] [Patent Document 1] Patent Publication (A) JP2013-101904 Summary of the Invention [Problem to be solved by the invention]

[0005] When pulling out a normal outlet plug from a power outlet, both hands must be used, making it difficult to pull out. Furthermore, pulling out an outlet plug from a power strip (extension cord) is even more difficult. For people with disabilities or elderly people, or for those in situations where it is difficult to use both hands due to the location of the outlet plug, it is necessary to make it easy to remove the outlet plug from the power strip.

[0006] Furthermore, when a conventional outlet plug is pulled out, it is difficult to apply a constant force in the vertical direction, which can result in an excessive load being placed on the outlet and outlet plug, reducing their durability. [Means for solving the problem]

[0007] For claims 1 and 2, the main body and the slide arm [Fig. 1] (1) [Fig. 5] (14) are made of plastic resin to give the slide arm shape (1, 14) elasticity. The slide arm [Fig. 2] (6) [Fig. 5] (18) molded integrally with the outlet plug is inserted into the guide hole (7, 19) on the main body side, allowing the slide arm to move in a certain direction [Fig. 3] (12) [Fig. 6] (23).

[0008] The slide arm portion [Fig. 3] (10), [Fig. 6] (20) is pushed from the left and right (11, 20) and bent, [Fig. 4] (11a), [Fig. 7] (20a), which pushes the pin [Fig. 3] (12), [Fig. 6] (23), downward toward the main body along the guide holes [Fig. 4] (12a), [Fig. 7] (23a).

[0009] The upper part of the slide arm in (5) and (14) of [Fig. 2] is curved inward to provide a better grip for the fingers, and the lower part (5, 14) is curved inward to allow for better movement within the guide hole.

[0010] [Fig. 2] and [Fig. 5] show the molded shape, [Fig. 1] shows the operable shape with the slide arm inserted, and [Fig. 6] shows the shape with the slide arm inserted and pushed from the left and right.

[0011] As for claim 2, the basic means is the same as claim 1, but it allows for a separate detachable type. The slide arm [Fig. 5] (14, 14a) is molded integrally with the lid-shaped main body [Fig. 5] (15) so that it can be attached to a variety of different shaped universal outlet plugs, and is shaped to prevent it from coming off. The slide arm bends outward to the left and right and is pressed firmly inward [Fig. 6] (21) to prevent it from falling off.

[0012] As for claims 3 and 4, the basic means are the same as those of claims 1 and 2, but the mounting position (1, 1a) of the slide arm and the position of the guide hole (2, 2a) shown in [Fig. 1] are changed to the 90° side surface (27, 27a) shown in [Fig. 8], and the mounting position (14, 14a) of the slide arm and the position of the guide hole (16, 16a) shown in [Fig. 5] are changed to the 90° side surface (31, 31a) shown in [Fig. 9].

[0013] The cross-sectional shape of the slide arm pin [Figure 1] (2a) and the cross-sectional shape of the guide hole (2b) can be determined arbitrarily depending on the molding conditions, etc. The same applies to claims 2, 3 and 4. Furthermore, the shapes of the cord connection parts shown in [Figure 1] (4) and [Figure 8] (34) are excluded from the scope of the present invention. Effect of the Invention

[0014] This outlet plug [Fig. 1][Fig. 8] and separate detachable outlet plug adapter [Fig. 5][Fig. 9] have a slide pin (12, 23, 30a) that can be moved downwards by the amount of deflection caused by pinching the slide arm portion (11, 20, 32, 33) with the fingers, making it easy to pull out the outlet plug from the power tap.

[0015] When removing the outlet plug, no excessive load is applied and only a weak force is used, making it easy to remove with one hand. This makes it easy for people with disabilities in their arms or hands, or for elderly people, to remove the outlet plug from the power strip. In addition, the power strip and the outlet plug are less likely to be subjected to excessive load, improving their durability.

[0016] Since the slide arm portion is molded integrally with the main body (5, 14), no additional parts are required, which is thought to result in superior durability and productivity, with minimal increase in costs. [Brief description of the drawings]

[Figure 9] These are three drawings of the molded shape of the outlet plug adapter type shown in [Figure 5], with the positions of the slide arms and guide holes (14, 16, 16a) shifted by 90 degrees to the positions shown in the side views (30, 31, 31a). [Figure 10]FIG. 10 is a front view of the adapter-type slide arm (31) of the outlet plug shown in FIG. 9 with both sides (32) pinched between fingers. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The left and right slide arms [Fig. 2] (5) that are molded as a single unit are inserted into the left and right slide guide holes (8, 8a) (7). Using the deflection of the plastic resin, the tip of the slide arm is moved downward [Fig. 3] (11) by the force of the fingers pinching it from the left and right [Fig. 3] (12), and the power tap is pushed to make it easier to pull out the outlet plug body.

[0019] The left and right slide arms are molded as one piece, eliminating the need for additional parts. The assembly process has been minimized to prevent any increase in costs. [Explanation of symbols]
