[0003] [Patent Document 1] JP 2020-148280 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of a design part that is formed in a frame shape and has no partitions in the middle, such as the decorative part described in Patent Document 1, the rigidity of the design part itself is not maintained, so the design part may deform after assembly, and parts other than those that are attached to other parts, such as the vertical wall part, may shift from their original positions. For this reason, it was difficult to make uniform the distance between the design part and the dial design, and the clearance with other molded parts, for example.

[0005] In view of the above problems, an object of the present invention is to provide an instrument device capable of preventing deformation of decorative parts. [Means for solving the problem]

[0006] The invention made to solve the above problem is an instrument device comprising a case, a dial attached to the case, and a frame-shaped design part arranged to cover the periphery of the dial, wherein the design part has positioning portions for the case at least at its four corners. Effect of the Invention

[0007] According to the present invention, since positioning portions are provided at least at the four corners of the decorative part, deformation of the decorative part can be prevented. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of an instrument device according to an embodiment of the present invention. In the following description, for convenience, the direction along the long side of a rectangle that is the shape of a case or the like is defined as the left-right direction, and the direction along the short side of the rectangle is defined as the up-down direction. The left-right direction corresponds to the width direction of a vehicle when the instrument device is installed in the vehicle. The up-down direction corresponds to the height direction of the vehicle when the instrument device is installed in the vehicle.

[0010] The instrument device 1 shown in Fig. 1 is mounted, for example, on an instrument panel in front of the driver's seat of a vehicle. The instrument device 1 includes a case 2, a dial 3, a bezel 4, and a face cover 5. As shown in Fig. 1, the instrument device 1 is assembled by stacking the case 2, the dial 3, the bezel 4, and the face cover 5 in this order.

[0011] Case 2 is a one-piece resin molded product having a substantially rectangular outer shape. Case 2 is formed with recesses and the like capable of accommodating electronic components and the like mounted on a substrate (not shown). On the substrate, for example, a driving motor for the indicating instrument, light-emitting elements for warning displays on dial 3, and driving circuits for driving them are mounted.

[0012] The dial 3 is a member consisting of a substantially rectangular plate body, and is a member on which various designs such as scales, patterns, symbols, characters, decorations, etc. are drawn according to information related to the vehicle in which the instrument device 1 is mounted. For example, a speedometer dial design, a rotary system dial design, etc. are drawn on the dial 3 by a well-known method such as printing.

[0013] As shown in Fig. 2, the bezel 4 is a design component formed in a substantially rectangular frame shape. Fig. 2 is a view of the watch with the end cover 5 removed from Fig. 1. The bezel 4 is disposed along the edge of the dial 3. The bezel 4 is composed of a frame portion 41 formed in an annular flat plate and a protrusion 42 formed on part of the inner circumference of the frame portion 41. The bezel 4 will be described in detail later.

[0014] The inside cover 5 is a frame-shaped enclosing member that surrounds the periphery of the dial 3 and the bezel 4 and holds the dial 3, the bezel 4, etc.

[0015] As shown in FIG. 2, holes 411 to 417 are provided in the frame portion 41 of the bezel 4. Hole 411 is provided in approximately the center of the upper side of the frame portion 41. Hole 412 is provided in approximately the right end of the upper side of the frame portion 41. Hole 413 is provided in approximately the center of the right side of the frame portion 41. Hole 414 is provided in approximately the right end of the lower side of the frame portion 41. Hole 415 is provided in approximately the left end of the lower side of the frame portion 41. Hole 416 is provided in approximately the center of the left side of the frame portion 41. Hole 417 is provided in approximately the left end of the upper side of the frame portion 41.

[0016] The pins 21-27 provided on the case 2 enter the holes 411-417 described above, thereby positioning the bezel 4 with respect to the case 2. The pins 21-27 are formed in a substantially cylindrical shape and are provided so as to protrude from the case 2. The pin 21 enters the hole 411. The pin 22 enters the hole 412. The pin 23 enters the hole 413. The pin 24 enters the hole 414. The pin 25 enters the hole 415. The pin 26 enters the hole 416. The pin 27 enters the hole 417.

[0017] Holes 411, 413, and 416 are substantially circular holes. On the other hand, holes 412, 414, 415, and 417 formed in the four corners of frame 41 are not circular. Details will be described with reference to FIGS.

[0018] Fig. 3 is an enlarged view of the portion indicated by A in Fig. 2. As shown in Fig. 3, hole 412 has flat portion 412a formed on the right side and flat portion 412b formed on the upper side. The portion other than flat portions 412a and 412b is arc-shaped. In other words, hole 412 is formed flat on the outer edge side of frame portion 41, and the movement of pin 22 within hole 412 relatively toward the outer edge (edge ​​portion on the outer periphery) side of frame portion 41 is restricted.

[0019] Fig. 4 is an enlarged view of the portion indicated by B in Fig. 2. As shown in Fig. 4, hole 414 has flat portion 414a formed on the right side and flat portion 414b formed on the bottom side. The portion other than flat portions 414a and 414b is arc-shaped. In other words, hole 414 is formed flat on the outer edge side of frame portion 41, and the pin 24 is restricted from moving relatively inside hole 414 toward the outer edge side of frame portion 41.

[0020] Fig. 5 is an enlarged view of the portion indicated by C in Fig. 2. As shown in Fig. 5, hole 415 has flat portion 415a formed on the left side and flat portion 415b formed on the lower side. The portion other than flat portions 415a and 415b is arc-shaped. In other words, hole 415 is formed flat on the outer edge side of frame portion 41, and pin 25 is restricted from moving relatively inside hole 415 toward the outer edge side of frame portion 41.

[0021] Fig. 6 is an enlarged view of the portion indicated by D in Fig. 2. As shown in Fig. 6, hole 417 has flat portion 417a formed on the left side and flat portion 417b formed on the upper side. The portion other than flat portions 417a and 417b is arc-shaped. In other words, hole 417 is formed flat on the outer edge side of frame portion 41, and pin 27 is restricted from moving relatively inside hole 417 toward the outer edge side of frame portion 41.

[0022] That is, the holes 412, 414, 415, and 417 are formed flat at least on the outer edge side of the frame portion 41. This prevents the bezel 4 from deforming overall toward the inside of the ring formed by the frame portion 41.

[0023] Further, a claw portion 418 is provided at approximately the center of the lower side of the frame portion 41 (see FIG. 2). The claw portion 418 will be described with reference to FIG. 7. The claw portion 418 is provided at approximately the center of the lower side of the frame portion 41. The claw portion 418 extends from the frame portion 41 toward the rear side of the case 2 (the side opposite to the side visible to the driver, etc.), and is engaged by being hooked onto the engaged portion 28, which is a rectangular column-shaped hole formed in the case 2. In other words, a claw-shaped portion such as a lance formed in the claw portion 418 engages with a hook portion, etc. formed in the engaged portion 28, thereby preventing the lower side portion of the bezel 4 from shifting toward the inner periphery of the frame portion 41.

[0024] In this embodiment, the claw portion 418 is provided on the lower side of the frame portion 41, but a hole may be provided so that a pin protruding from the case 2 can be inserted therein. Also, the claw portion 418 may be provided on a side other than the lower side.

[0025] According to this embodiment, the instrument device 1 includes a case 2, a dial 3 attached to the case 2, and a frame-shaped bezel 4 provided to cover the periphery of the dial 3. The bezel 4 is provided with holes 412, 414, 415, and 417, which serve as positioning portions with respect to the case 2, at least in its four corners.

[0026] By configuring the instrument device 1 as described above, holes are provided at least in the four corners of the bezel 4, so deformation of the bezel 4 can be prevented without providing partitions or the like. Therefore, for example, the distance between the bezel 4 and the design of the dial 3 and the alignment with the back cover 5 can be made uniform.

[0027] In addition, since the holes 412, 414, 415, and 417 have flat portions formed at least on the outer edge side of the frame portion 41, for example, the pin 22 inserted into the hole 412 can be restricted from moving relatively outward. Therefore, it is possible to more effectively prevent the frame portion 41 from losing its rigidity and deforming inward.

[0028] Moreover, in addition to the holes 412, 414, 415, and 417, the bezel 4 is provided with a claw portion 418 that engages with the case 2. By doing so, together with the holes 412, 414, 415, and 417, deformation of the bezel can be prevented.

[0029] The present invention is not limited to the above-described embodiment. In other words, a person skilled in the art can implement the present invention by modifying it in various ways in accordance with conventional knowledge without departing from the gist of the present invention. As long as the instrument device of the present invention is still provided even after such modification, it is of course included in the scope of the present invention. [Explanation of symbols]
