Operating device and method for assembling the operating device

Abstract

To improve assembly. [Solution] In the operating device 10, a stopper 54 is provided on the push knob 40, and in the non-assembled position of the push knob 40, the arm portion 72 of the stabilizer 70 connected to the push knob 40 is supported from below by the stopper 54, thereby positioning the stabilizer 70 in the temporary assembly position. When assembling the push knob 40 to which the stabilizer 70 is connected from the non-assembled position to the support cylinder portion 21 of the case 20, the first engaged portion 72B of the arm portion 72 abuts against the guide portion 24 of the case 20 from above, causing the stabilizer 70 to rotate upward from the temporary assembly position, and the first engaged portion 72B is displaced forward along the guide portion 24 and inserted into the first engagement groove 23A. Therefore, it is no longer necessary for the worker to align the position of the first engaged portion 72B with respect to the first engagement groove 23A while assembling the push knob 40 to the support cylinder portion 21. Thus, the ease of assembly of the operating device 10 can be improved.

[Modes for carrying out the invention]

[0010] The operating device 10 according to this embodiment will be described below with reference to the drawings. The arrows UP, FR, and RH shown in the drawings indicate the upper, front, and right sides of the operating device 10, respectively. In the following description, when using the directions of up / down, front / back, and left / right, they refer to the up / down, front / back, and left / right directions of the operating device 10, unless otherwise specified.

[0011] As shown in Figures 1 to 5, the operating device 10 is composed of a case 20 as a base member, a cover 30, a push knob 40 as a knob, a stabilizer 70, and a substrate 80.

[0012] (Regarding Case 20) As shown in Figure 6, the case 20 is formed in a substantially rectangular box shape, open to the bottom and with the left-right direction as its longitudinal direction. The interior of the case 20 is a substrate housing section 20A for housing the substrate 80, which will be described later. Multiple (four in this embodiment) support cylinder sections 21 are provided on the rear of the upper wall of the case 20. The support cylinder sections 21 are formed in a substantially rectangular cylindrical shape with the vertical direction as their axial direction and extend upward from the case 20. The interior of the support cylinder sections 21 is through. The four support cylinder sections 21 are arranged side by side with a predetermined gap between them in the left-right direction, and the lower ends of adjacent support cylinder sections 21 are connected by connecting sections 21A. Claw sections 21B are formed on the front and rear surfaces of the first and fourth support cylinder sections 21 from the right, respectively.

[0013] A switch housing section 22 for housing a switch 82 (described later) is provided approximately in the center of the upper wall of the case 20. The switch housing section 22 is formed in a roughly rectangular box shape that is open to the bottom and protrudes upward from the case 20. The switch housing section 22 is positioned to overlap the front walls of the second and third support cylinder sections 21 from the right. A roughly rectangular through-hole 22A (see Figure 6) is formed through the upper wall of the switch housing section 22 approximately in the center. The through-hole 22A is located between the second and third support cylinder sections 21 from the right and in front of the support cylinder sections 21. A case-side cover section 22B is provided on the upper surface of the switch housing section 22. The case-side cover section 22B extends upward from the left and right edges and the front edge of the through-hole 22A, and the rear end of the case-side cover section 22B is connected to the front surface of the support cylinder section 21.

[0014] A pair of left and right first engaging portions 23 are provided at the front end of the upper surface of the case 20. The first engaging portions 23 are formed in a substantially rectangular block shape and are located outward in the left-right direction from the four support cylinder portions 21. A first engaging groove 23A (see Figures 4 and 5) is formed on the left-right inner surface of the first engaging portion 23, and the rear end of the first engaging groove 23A is open to the rear. That is, the first engaging groove 23A has a pair of upper and lower engaging surfaces 23B.

[0015] On the upper surface of the case 20, a pair of left and right guide portions 24 are provided. The guide portions 24 are arranged adjacent to the rear side of the first engaging portion 23. The guide portions 24 are formed in a rib shape extending in the front-rear direction with the left-right direction as the plate thickness direction, and extend rearward from the inner ends in the left-right direction of the rear surface in the first engaging portion 23. The upper surface of the guide portion 24 is a guide surface 24A. The guide surface 24A is arranged flush with the engaging surface 23B on the lower side in the first engaging groove 23A, and the guide surface 24A and the lower engaging surface 23B are continuously formed (see FIG. 5).

[0016] At the front end portion of the upper surface of the case 20, a second engaging portion 25 is provided at the center in the left-right direction. The second engaging portion 25 is formed in a substantially U-shaped block shape that is open to the rear in a plan view. That is, a second engaging groove 25A that is open upward and rearward is formed in the middle portion in the left-right direction of the second engaging portion 25. The front wall of the second engaging portion 25 protrudes upward compared to the left and right side walls.

[0017] On the upper surface of the case 20, fixing bosses 26 for fixing a substrate 80 described later are provided at the four corner portions of the case 20. The fixing bosses 26 are formed in a substantially bottomed cylindrical shape that is open downward and protrude upward from the case 20.

[0018] (Regarding the cover 30) As shown in FIGS. 1 to 4, the cover 30 is formed in a substantially rectangular box shape that is open upward and has the left-right direction as the longitudinal direction. The cover 30 is arranged in the substrate housing portion 20A of the case 20, and the four corner portions of the cover 30 are fixed to the case 20 together with a substrate 80 described later by fixing screws (not shown) screwed into the fixing bosses 26.

[0019] (Push knob 40) As shown in Figures 1 to 5, the push knob 40 is connected to four support cylinder portions 21 in the case 20 so as to be movable in the vertical direction, and is configured to be pressed downward by the operator. Specifically, the push knob 40 is positioned in a non-operational position (as shown in Figures 1, 2, 4, and 5), and by pressing the push knob 40 downward (towards arrow A in Figure 5), the push knob 40 moves downward from the non-operational position to press the switch 82, which will be described later. The push knob 40 is composed of a knob slider 50 and an operation knob 60.

[0020] (Regarding the Knob Slider 50) The knob slider 50 is formed in a roughly rectangular box shape that is open to the bottom and extends in the left-right direction. The knob slider 50 is externally mounted from above to four support cylinder portions 21 in the case 20 and is supported by the support cylinder portions 21 so as to be movable in the vertical direction.

[0021] A pair of left and right engaging pieces 50A are provided on the lower part of the front and rear walls of the knob slider 50, at positions corresponding to the claw portion 21B of the case 20. Slits 50B extending vertically and opening downward are formed on both the left and right sides of the engaging piece 50A in the front and rear walls of the knob slider 50. This allows the engaging piece 50A to be elastically deformable in the front-rear direction starting from its upper end. A rectangular engaging hole 50C is formed through the engaging piece 50A. The claw portion 21B of the case 20 is fitted into the engaging hole 50C by snap-fit ​​fitting and abuts against the lower inner surface of the engaging hole 50C. This restricts the upward movement of the knob slider 50 (push knob 40) in the non-operating position.

[0022] A knob-side cover portion 51 is formed on the front wall of the knob slider 50 at a position corresponding to the case-side cover portion 22B of the case 20. The knob-side cover portion 51 is formed in a roughly rectangular box shape that is open to the bottom and protrudes forward from the knob slider 50. The knob-side cover portion 51 is open to the rear so that the inside of the knob-side cover portion 51 and the inside of the knob slider 50 are in communication. The upper part of the case-side cover portion 22B of the case 20 is positioned inside the knob-side cover portion 51.

[0023] A switch pressing portion 51A (see Figures 3 and 4) is provided on the upper wall of the knob-side cover portion 51. The switch pressing portion 51A is formed in a roughly cross-shaped column extending in the vertical direction and extends downward from the upper wall of the knob-side cover portion 51. The lower end of the switch pressing portion 51A is inserted through the insertion hole 22A of the case 20 and is positioned inside the switch housing portion 22. The switch pressing portion 51A is positioned adjacent to the upper side of the switch 82, which will be described later. This restricts the downward movement of the push knob 40 in the non-operation position.

[0024] The knob slider 50 has three partition walls 52 (see Figure 3) inside. The partition walls 52 are formed in the shape of rectangular plates with the left-right direction being the thickness direction, and are positioned between the support cylinder portions 21 of adjacent cases 20 in the left-right direction. The partition walls 52 extend downward from the upper wall of the knob slider 50, with the front end of each partition wall 52 connected to the front wall of the knob slider 50 and the rear end of each partition wall 52 connected to the rear wall of the knob slider 50. The front end of the second partition wall 52 from the left is connected to the switch pressing portion 51A.

[0025] As shown in Figures 3 and 7, the lower ends of both the left and right sides of the knob slider 50 are provided with arm support portions 53 at their front ends to support the arm portions 72 of the stabilizer 70, which will be described later. The arm support portions 53 are formed in a substantially U-shaped block that opens to the front when viewed from the outside in the left-right direction of the knob slider 50, and protrude outward in the left-right direction from the sides of the knob slider 50. That is, the arm support portions 53 have support grooves 53A that open outward in the left-right direction and to the front. The bottom surface of the support grooves 53A is located outward in the left-right direction from the sides of the knob slider 50. An inclined surface 53B is formed at the front end of the bottom surface of the support grooves 53A. The inclined surface 53B is inclined inward in the left-right direction as it approaches the front. A circular support hole 53C is formed at the rear end of the bottom surface of the support grooves 53A. The support hole 53C is formed in a concave shape that opens outward in the left-right direction. The diameter of the support hole 53C is approximately the same as the width dimension of the support groove 53A.

[0026] On both the left and right sides of the knob slider 50, stoppers 54 are provided as support parts below the support holes 53C. The stoppers 54 are formed in a roughly triangular prism shape and protrude outward from the sides of the knob slider 50 in the left and right directions. The stoppers 54 have a stopper surface 54A for restricting the rotation of the stabilizer 70, which will be described later, and the stopper surface 54A is inclined downward as it approaches the front in a side view.

[0027] (Regarding control knob 60) As shown in Figures 1 to 5, the operating knob 60 is formed in a roughly rectangular box shape that is open to the bottom and extends in the left-right direction. The operating knob 60 is attached to the upper end of the knob slider 50 from above and is fixed to the knob slider 50 by a snap-fit ​​fitting. In other words, the operating knob 60 is assembled to the knob slider 50 so that it cannot move relative to it.

[0028] (Regarding Stabilizer 70) The stabilizer 70 is made of resin. The stabilizer 70 is composed of a pair of left and right arm portions 72 and a connecting plate portion 74 which serves as a connecting portion for linking the pair of arm portions 72. The arm portions 72 constitute both ends of the stabilizer 70 in the left and right directions. The arm portions 72 are formed in a substantially elongated plate shape with the left and right direction being the thickness direction and extending substantially in the front and rear direction. A rotating shaft 72A is provided at the rear end (base end) of the arm portion 72. The rotating shaft 72A is formed in a substantially track-shaped column with the vertical direction being the longitudinal direction and protrudes inward from the arm portion 72 in the left and right directions. The arm portions 72 are positioned on the left and right outer sides of the knob slider 50, and the rotating shaft 72A is inserted into the support hole 53C of the knob slider 50 and rotatably supported in the support hole 53C. In this way, the stabilizer 70 is connected to the push knob 40 so as to be rotatable in the left and right direction and so as to be integrally movable in the up and down direction.

[0029] A first engaged portion 72B is provided at the tip of the arm portion 72. The first engaged portion 72B is formed in a substantially cylindrical shape with the left-right direction as its axial direction. The arm portion 72 has a pair of upper and lower notches 72C formed on the base end side of the arm portion 72 relative to the first engaged portion 72B, which are open outward in the vertical direction. The left-right inner end of the first engaged portion 72B protrudes inward in the left-right direction from the arm portion 72. The first engaged portion 72B is inserted from the rear into the first engagement groove 23A of the first engagement portion 23 in the case 20 and is engaged with the first engagement groove 23A in the vertical direction (this is the position shown in Figures 4 and 5, and hereafter this position of the stabilizer 70 will be referred to as the initial position). In other words, the first engaged portion 72B is connected to the first engagement portion 23 so as not to move relative to it in the vertical direction and so as to move relative to it in the front-rear direction.

[0030] In the initial position of the stabilizer 70, the arm portion 72 extends forward from the knob slider 50 and is positioned spaced apart from the stopper 54 of the knob slider 50 on one side in the rotational direction. Specifically, in the initial position of the stabilizer 70, the arm portion 72 extends forward from the knob slider 50 such that the first engaged portion 72B is positioned slightly below the rotation axis 72A. When the push knob 40 moves downward from the non-operated position due to a pressing operation, the vertical movement of the first engaged portion 72B is restricted, causing the arm portion 72 to rotate on one side in the rotational direction (towards arrow B in Figure 5).

[0031] As will be explained in more detail later, as shown in Figure 8(B), before the stabilizer 70 is assembled to the case 20 of the push knob 40, the stabilizer 70 is rotated by its own weight to the other side of the rotational direction (towards arrow D in Figure 8) in a temporary assembly position. At this position, the arm portion 72 contacts the stopper surface 54A of the stopper 54, thereby restricting the rotation of the stabilizer 70 to the other side of the rotational direction. In the temporary assembly position of the stabilizer 70, the stabilizer 70 is positioned to extend forward and downward from the push knob 40 in a side view. Furthermore, the inclination angle of the stabilizer 70 relative to the push knob 40 is set so that the first engaged portion 72B of the stabilizer 70 contacts the rear guide portion 24 of the first engaged portion 23 when the push knob 40 is assembled to the case 20.

[0032] The connecting plate portion 74 is formed in the shape of a substantially rectangular plate with the width direction (vertical direction) of the arm portion 72 as the plate thickness direction and extending in the left-right direction. The connecting plate portion 74 is positioned between the arm portions 72, and both left-right ends of the connecting plate portion 74 are connected to the front ends of the arm portions 72. As a result, both longitudinal ends (left-right ends) of the push knob 40 are connected by a stabilizer 70 that engages with the case 20 in the vertical direction. Therefore, the tilt of the push knob 40 in the left-right direction is suppressed by the stabilizer 70, and the push knob 40 is configured to move smoothly in the vertical direction relative to the support cylinder portion 21 of the case 20.

[0033] At the front end of the connecting plate portion 74, a pair of upper and lower second engaging portions 74A are provided in the center in the left-right direction. The second engaging portions 74A are formed in a substantially rectangular plate shape with the left-right direction as the thickness direction and protrude outward from the connecting plate portion 74 in the thickness direction. The lower second engaging portion 74A is inserted from the rear into the second engaging groove 25A of the second engaging portion 25 and engages with the second engaging groove 25A in the left-right direction. As a result, the left-right displacement of the connecting plate portion 74 with respect to the base ends of the pair of arm portions 72 is suppressed by the second engaging portion 25 and the second engaging portions 74A, so that the stabilizer 70 rotates smoothly when the push knob 40 is pressed.

[0034] The stabilizer 70 has a shape that is symmetrical with respect to a plane of symmetry S (see Figure 5) that passes through the center of the rotation axis 72A and is positioned along the extending direction of the arm portion 72. This configuration allows the stabilizer 70 to be assembled to the knob slider 50 and case 20 even when the stabilizer 70 is inverted.

[0035] (Regarding circuit board 80) As shown in Figures 4 and 5, the substrate 80 is formed in a substantially rectangular plate shape with the vertical direction being the thickness direction and the horizontal direction being the longitudinal direction. The substrate 80 is housed in the substrate housing section 20A of the case 20 and is fixed together with the cover 30 to the upper wall of the case 20 by fixing screws (not shown) that are screwed into the fixing bosses 26 of the case 20.

[0036] A switch 82 (see Figure 4) is provided on the upper surface of the circuit board 80, and the switch 82 is housed in the switch housing 22 of the case 20. The switch 82 is a push switch and is positioned adjacent to the lower side of the switch pressing portion 51A of the push knob 40. When the push knob 40 is pressed, the switch 82 switches from off to on.

[0037] (Effects and Benefits) Next, the operation and effects of this embodiment will be explained while describing the assembly procedure of the stabilizer 70 to the push knob 40 and case 20 in the operating device 10.

[0038] In assembling the stabilizer 70 to the push knob 40 and case 20, the stabilizer 70 is first rotatably connected to the push knob 40 and positioned in a temporary assembly position (first step). Specifically, as shown in Figure 8(A), the rotation axis 72A of the stabilizer 70 is positioned in front of the arm support portion 53 of the knob slider 50. At this time, the posture of the stabilizer 70 is set such that the arm portion 72 of the stabilizer 70 is positioned on one side in the rotational direction relative to the temporary assembly position. In Figure 8(A), the posture is shown with the arm portion 72 positioned approximately horizontally when viewed from the left and right directions.

[0039] Next, the stabilizer 70 is moved to the rear (towards the direction of arrow (C) in Figure 8(A)), and the rotating shaft 72A is inserted into the support groove 53A of the knob slider 50 from the front. At this time, the rotating shaft 72A is pressed by the inclined surface 53B of the support groove 53A, and the arm portion 72 elastically deforms outward in the left-right direction. When the stabilizer 70 is moved further to the rear and the rotating shaft 72A reaches the support hole 53C, the arm portion 72 elastically deforms inward in the left-right direction, and the rotating shaft 72A is fitted into the support hole 53C. As a result, the stabilizer 70 is rotatably connected to the push knob 40.

[0040] Furthermore, when the stabilizer 70 is connected to the push knob 40, the stabilizer 70 tends to hang from the push knob 40 due to its own weight. As a result, the stabilizer 70 rotates from the connection position to the push knob 40 (the position of the stabilizer 70 shown by the dashed line in Figure 8(B)) to the other side in the rotational direction (the direction of arrow (D) in Figure 8(B)). Consequently, the arm portion 72 of the stabilizer 70 comes into contact with the stopper surface 54A of the stopper 54 of the knob slider 50, and the stabilizer 70 is positioned in the temporary assembly position (see the stabilizer 70 shown by the solid line in Figure 8(B)). In other words, the stabilizer 70 (arm portion 72) is supported from below by the stopper 54 so that it extends forward and downward from the push knob 40 when viewed from the left and right directions.

[0041] Next, the push knob 40 to which the stabilizer 70 is connected is assembled from above to the four support cylinder portions 21 of the case 20 and positioned in the non-pressed position (second step). Specifically, the push knob 40 is positioned spaced apart above the support cylinder portions 21 (this position of the push knob 40 is called the non-assembled position). Then, the push knob 40 is moved downward from the non-assembled position and assembled to the support cylinder portion 21. Here, as shown in Figure 9(A), when the push knob 40 is assembled to the support cylinder portion 21, the first engaged portion 72B of the stabilizer 70 comes into contact with the guide surface 24A of the guide portion 24 in the case 20.

[0042] If the stabilizer 70 is moved further downward from this state (towards the direction of arrow A in Figure 9(A)), the downward movement of the first engaged portion 72B is restricted by the guide surface 24A, causing the stabilizer 70 to rotate relative to the push knob 40 in one direction (towards the direction of arrow B in Figure 9(A), which is upward). That is, the first engaged portion 72B slides on the guide surface 24A and is displaced forward (towards the direction of arrow E in Figure 9(A)). As a result, the first engaged portion 72B is inserted into the first engagement groove 23A, as shown in Figure 9(B).

[0043] As the stabilizer 70 is moved further downward (in the direction of arrow A in Figure 9(B)), the stabilizer 70 rotates further relative to the push knob 40 in one direction (in the direction of arrow B in Figure 9(B)), as described above, and the first engaged portion 72B slides on the lower engaging surface 23B of the first engaging groove 23A and is displaced forward (in the direction of arrow E in Figure 9(B)). As shown in Figure 5, when the push knob 40 is lowered to the pressed position, the entire first engaged portion 72B is inserted into the first engaging groove 23A, and the stabilizer 70 is positioned in its initial position. As a result, in the second step, the first engaged portion 72B of the stabilizer 70 in the temporary assembly position comes into contact with the guide surface 24A of the guide portion 24, causing the stabilizer 70 to rotate in one direction in the rotational direction, and the first engaged portion 72B is displaced forward along the guide surface 24A and inserted into the first engagement groove 23A.

[0044] In the second step, the claw portion 21B of the support cylinder portion 21 is inserted into the engagement hole 50C of the push knob 40 by snap-fit ​​fitting. Also in the second step, when the stabilizer 70 rotates relative to the push knob 40 in one direction, the second engaged portion 74A of the stabilizer 70 is inserted from the rear into the second engagement groove 25A of the second engagement portion 25 in the case 20, and the second engaged portion 74A and the second engagement portion 25 are engaged in the left-right direction.

[0045] As explained above, in the operating device 10, a stopper 54 is provided on the push knob 40. In the non-assembled position of the push knob 40, the arm portion 72 of the stabilizer 70 connected to the push knob 40 is supported from below by the stopper 54, and the stabilizer 70 is positioned in the temporary assembly position. When assembling the push knob 40, to which the stabilizer 70 is connected, from the non-assembled position to the support cylinder portion 21 of the case 20, the first engaged portion 72B of the arm portion 72 abuts against the guide portion 24 of the case 20 from above, causing the stabilizer 70 to rotate upward from the temporary assembly position, and the first engaged portion 72B is displaced forward along the guide portion 24 and inserted into the first engagement groove 23A. Therefore, it is no longer necessary for the operator to align the position of the first engaged portion 72B with respect to the first engagement groove 23A while assembling the push knob 40 to the support cylinder portion 21. Therefore, the workability during the assembly of the stabilizer 70 can be improved, and the assembly of the operating device 10 can also be improved.

[0046] Furthermore, in case 20, the lower engagement surface 23B of the first engagement groove 23A and the guide surface 24A of the guide portion 24 are arranged flush with each other. That is, there is no step between the lower engagement surface 23B and the guide surface 24A, and the engagement surface 23B and the guide surface 24A are formed continuously. As a result, in the second step, the first engaged portion 72B of the stabilizer 70 can be displaced forward along the guide surface 24A and the lower engagement surface 23B, and smoothly inserted into the first engagement groove 23A.

[0047] Furthermore, a second engaged portion 74A is provided in the left-right intermediate portion of the connecting plate portion 74 of the stabilizer 70. In the second step, the second engaged portion 74A is inserted from the rear into the second engagement groove 25A of the second engagement portion 25 in the case 20, and the second engaged portion 74A and the second engagement portion 25 are engaged in the left-right direction. In other words, in the second step, the second engaged portion 74A, which suppresses the left-right displacement of the stabilizer 70, can be automatically inserted into the second engagement groove 25A and assembled to the case 20.

[0048] Furthermore, the stabilizer 70 is provided with a pair of upper and lower second engaging portions 74A, and the stabilizer 70 has a shape that is symmetrical with respect to a plane of symmetry S that passes through the center of the rotation axis 72A and is along the extending direction of the arm portion 72. This allows the stabilizer 70 to be assembled to the push knob 40 and case 20 in an inverted state. Therefore, in the first step, the stabilizer 70 can be assembled to the push knob 40 without paying attention to the orientation of the stabilizer 70 relative to the push knob 40. Thus, the workability when assembling the stabilizer 70 to the push knob 40 can be further improved.

[0049] In this embodiment, a pair of upper and lower second engagement portions 74A are provided on the stabilizer 70, but the upper second engagement portion 74A may be omitted. In this case, in the first step, the stabilizer 70 is assembled to the push knob 40 while aligning the orientation of the stabilizer 70 with that of the push knob 40.

[0050] Furthermore, the present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. [Explanation of symbols]
