Description

Handles and wiring equipment

[0001] The present disclosure relates to a handle and a wiring device, and more particularly to a handle provided in a wiring device for operating a switch that controls a load, and a wiring device provided with such a handle and a switch.

[0002] In the handle described in Patent Document 1, a colored base portion is formed by primary molding, and then a colorless surface layer is formed on the front surface of the base portion by secondary molding (i.e., a handle with a two-layer structure is formed). In this handle, if there is a thick portion such as a tab on the back surface (rear surface) of the base portion during primary molding of the base portion, a sink mark (indentation) may occur on the front surface of the base portion at a position corresponding to the thick portion. The sink mark that occurs on the front surface of the base portion becomes less noticeable when the front side of the base portion and the surface layer are fused and bonded to each other during secondary molding of the surface layer.

[0003] However, in the handle described in Patent Document 1, if the secondary molding of the surface layer on the base portion is omitted (i.e., one-color molding is used), sink marks that occur on the front surface of the base portion become noticeable.

[0004] Furthermore, for example, in the case of a handle having an assembly structure in which the handle body (base part) has an opening and a lid part such as a name cover is fitted into the opening, even if the handle body is subjected to secondary molding after the lid part is primarily molded, the front of the handle body will be exposed, and therefore any sink marks that occur on the front will be noticeable.

[0011] (1) Overview First, an overview of a wiring device 100 according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 5. FIG.

[0012] 1, wiring device 100 includes switch 10 for controlling a load and handle 1 for operating switch 10. Switch 10 is attached to a rear surface 11B of a handle body 11, which will be described later.

[0013] The load may be, for example, a lighting fixture, but may also be an air conditioning device or the like, and the type of load does not matter. The switch 10 is embedded in a construction material. The construction material is a material that constitutes a structure such as a building, for example, a wall surface of a building.

[0014] (1-1) Handle The handle 1 includes a handle body 11 as shown in FIGS.

[0015] (1-1-1) Handle Body The handle body 11 is the main body of the handle 1. The handle body 11 is a molded product made of synthetic resin. The synthetic resin that is the material of the handle body 11 is, for example, a thermoplastic resin, and in this embodiment, is ABS (acrylonitrile butadiene styrene) resin.

[0016] (1-1-1a) Rear Surface The rear surface 11B is the surface of the pair of main surfaces of the handle body 11 that faces the switch 10, and may be referred to as the "opposing surface." As shown in FIG. 5, the rear surface 11B has one or more (e.g., two) protrusions 111 and one or more (e.g., two) recessed portions TN1.

[0017] (1-1-1aA) Protruding Part The protruding part 111 is a part that protrudes rearward from the rear surface 11B of the handle body 11, as shown in Figures 3 to 5. The "rearward" refers to the direction from the front surface 11F (described later), which is the surface of the handle body 11 opposite the rear surface 11B, toward the rear surface 11B.

[0018] (1-1-1aB) Lightening Hole The lightening hole TN1 is a space provided in a region 111N adjacent to the protruding portion 111 on the rear surface 11B, as shown in FIG.

[0019] The lightening portion TN1 is a space free of synthetic resin that is provided in at least one of the protrusion 111 and the region 111N adjacent to the protrusion 111 in order to reduce the volume (amount of synthetic resin) of the protrusion 111 and the region 111N adjacent to the protrusion 111. Specifically, the lightening portion TN1 is a notch, but may also be a hole or the like. The notch is a notch-shaped space.

[0020] By providing the lightening hole TN1 in this way, a portion (thin portion) that is relatively thinner than the thickness of other portions is created at least in the thick portion of the protrusion 111 etc. and in the vicinity of the thick portion.

[0021] In this embodiment, the region 111N is the region on the rear surface 11B between the right end portion 11R and the protrusion 111, and the lightening portion TN1 is a cutout portion provided in the wall portion 111W formed in part of such region 111N.

[0022] 1 and 2, the front surface 11F is the surface opposite the rear surface 11B of the pair of main surfaces of the handle body 11. The front surface 11F is an operating surface operated by the operator.

[0023] (1-2) Advantages According to the above configuration, by providing the lightening portion TN1 in the region 111N close to the protrusion 111 on the rear surface 11B side of the handle body 11, it is possible to suppress the occurrence of sink marks at the position corresponding to the protrusion 111 (i.e., the back side of the protrusion 111) on the front surface 11F of the handle body 11. A sink mark is a "depression" that occurs on the surface of a molded product (the back side of a thick portion such as a claw).

[0024] In particular, the occurrence of sink marks on the front surface 11F, which is the operating surface, is suppressed, so that a handle can be provided that can solve the problem that sink marks become noticeable when secondary molding of the surface layer is omitted.

[0025] (2) Details Next, details of the wiring device 100 will be described using Figures 1 to 8C. Note that the following description will omit or simplify the description of previously mentioned matters.

[0061] (3) Modifications Various modifications will be described below. Note that, in the following, descriptions of matters common to the embodiment will be omitted or simplified, and differences from the embodiment will be described in detail.

[0062] (3-1) Modifications Regarding Arrangement of First Protrusion The first protrusion 111 may be formed near the left end 11L. The left end 11L is the end on the left side of the handle body 11. Alternatively, the first protrusion 111 may be formed near each of the right end 11R and the left end 11L. Alternatively, the first protrusion 111 may be formed on the rear surface 11B at a position away from the end of the body.

[0063] (3-2) Modifications Related to the Function of the First Protrusion In the embodiment, the first protrusion 111 is the main body side protrusion 111 (claw) that fits into the insertion hole 10h of the switch 10, but it may be, for example, another main body side protrusion that fits into a hole other than the insertion hole 10h of the switch 10, or a thick portion that has a function other than fitting. Examples of thick portions that have a function other than fitting include a rib for increasing the strength of the handle main body 11, or a protrusion for positioning the switch 10 relative to the handle main body 11.

[0064] (3-3) Modifications of the First Region In the embodiment, the first region 111N adjacent to the first protrusion 111 was the region between the protrusion 111 and the right end 11R (in other words, the region on the right side of the protrusion 111: see FIG. 5 ), but it may be, for example, the region on the left side of the protrusion 111, or the region above or below the protrusion 111. Alternatively, the region 111N may be two or more of the region on the right side, left side, upper side, and lower side of the protrusion 111.

[0065] (3-4) First modified example of first cutout portion In the embodiment, the first cutout portion TN1 was a notch provided in the first wall portion 111W and of the same thickness as the first wall portion 111W (i.e., a notch from the rear end of the first wall portion 111W to the front end of the first wall portion 111W: see Figure 5), but it may also be a notch that reaches from the rear end of the first wall portion 111W to the inside of the handle body 11 (i.e., a notch that is deeper than the notch portion TN1 in Figure 5).

[0066] In other words, the thickness of the first recessed portion TN1 in the front-to-rear direction (the depth of the notch portion TN1 in FIG. 5) may be greater than the thickness of the first wall portion 111W, but less than the sum of the thickness of the first wall portion 111W and the thickness of the handle body 11. This creates a thinner portion, which can further suppress the occurrence of sink marks.

[0067] (3-5) Second Modification of First Hollow Portion The first hollow portion TN1 is not limited to the notch portion TN1 shown in Fig. 5, and may be, for example, a hole provided in the first wall portion 111W, or a notch or hole provided in the first protruding portion 111. In either case, the amount of synthetic resin in the thick portion including the first protruding portion 111 and the first wall portion 111W in the vicinity thereof is reduced, thereby making it possible to suppress the occurrence of sink marks.

[0068] (3-6) Modified example of second cutout portion In the embodiment, the second cutout portion TN4 is three holes TN4 (see Figures 8A and 8C), but it may also be a single hole TN4 having a U-shape with an open back, as shown in Figures 9A and 9B.

[0069] (3-7) Modified Examples of Holes In the embodiment, the hole TN4 (see FIGS. 8A and 8C) does not penetrate the fitting portion 114, but it may penetrate the fitting portion 114. The hole TN4 may be, for example, a hole that penetrates a pair of opposing portions of the side wall 114W (see FIG. 8B) of the fitting portion 114 in the left-right direction.

[0070] (3-8) Modified example of the positional relationship between the protrusion and the mating portion In this embodiment, a protrusion 111 is formed on the right end 11R and a mating portion 114 is formed on the left end 11L of the rear surface 11B of the handle body 11 (see Figure 3), but the positional relationship between the protrusion 111 and the mating portion 114 may be reversed from that in Figure 3.

[0071] (3-9) Modifications of the Handle Body Material The handle body 11 may be made of a thermoplastic resin other than ABS. Examples of thermoplastic resins other than ABS include, but are not limited to, PCABS (polycarbonate ABS) and ASA (acrylonitrile styrene acrylate).

[0072] (3-10) Modifications of the Function and Material of the Lid The lid 12 may be a resin molded product other than a name cover, such as a light diffusion plate, etc. The material of the lid 12 may be a transparent resin other than acrylic resin.

[0073] (3-11) Modification of the Front Surface: Texturing The front surface 11F may be textured. Texturing is a type of surface treatment in which a wrinkled pattern (texture) is physically applied to the front surface 11F of the handle body 11. This modification provides a handle that can solve the problem that applying texture to the front surface 11F without a surface layer makes sink marks more noticeable.
