[Figure 8] 1 is a cross-sectional view of a portion of a configuration of a lever switch according to the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] <Embodiment 1> The present disclosure will be described with reference to the drawings.

[0011] The lever switch in this embodiment is equipped on a vehicle and is used to operate devices mounted on the vehicle, such as wipers and lights. As shown in Fig. 1A, the entire lever switch is configured with a lever 2 connected to a steering column portion of the vehicle, indicated by reference numeral 3, and a tip portion 1 connected to the lever 2. In this embodiment, the tip portion 1 of the entire lever switch shown in Fig. 1A will be referred to as the lever switch and will be described in detail.

[0012] As shown in Fig. 1B, the lever switch, which is the tip portion 1 of the entire lever switch, is configured to include a shaft 10 having a predetermined length, and an operation knob 20 attached to the tip side of the shaft 10, which is the upper side in Fig. 1B. The lever switch is configured to allow a rotation operation in which the tip side, which is the upper side in Fig. 1B, rotates around the base of the shaft 10 as shown by an arrow Y1, and a rotation operation in which the operation knob 20 on the tip side rotates around the axis of the shaft 10 as shown by an arrow Y2. The detailed configuration of the lever switch will be described below.

[0013] 1B, the lever switch has a shaft 10 whose upper side is covered by an operation knob 20 and whose lower side is covered by a case 30. FIG.

[0014] The operation knob 20 has a predetermined length along the axial direction of the shaft 10, and is formed of a member having an annular side wall formed with an inner diameter larger than the diameter of the shaft 10. In this embodiment, the operation knob 20 is formed in a substantially cylindrical shape, and one end in the axial direction of the operation knob 20 located on the upper side of Fig. 2 is an annular end face formed so that the central portion is open and only the outer circumferential side is closed, and the other end in the longitudinal direction of the operation knob 20 located on the lower side of Fig. 2 is open. Then, as described later, the shaft 10 is inserted into the annular portion of the operation knob 20 from the other end side, and the operation knob 20 is attached to the tip side of the shaft 10.

[0015] The inner surface of the side wall of the operation knob 20 is provided with a knob-side claw portion 21 (engagement portion) that protrudes toward the inside of the annular portion, that is, toward the shaft 10 to which the operation knob 20 is attached, in the axial center direction. Specifically, the knob-side claw portion 21 is provided on the inner surface of the side wall of the operation knob 20 at a predetermined length position in the longitudinal direction, and is further provided at two mutually opposing positions on the inner surface. That is, a plurality of knob-side claw portions 21 are provided symmetrically with respect to the axis of the operation knob 20. Then, the knob-side claw portion 21 engages with the claw portion 11 that protrudes toward the side wall of the operation knob 20 from the shaft 10 inserted into the annular portion of the operation knob 20, as described later. At this time, the knob-side claw portion 21 is formed with an inclination so that the protruding height gradually increases from the other end side toward the one end side of the operation knob 20. However, the knob-side claw portion 21 is not limited to the position and number shown in FIG. 2, and may be formed at any position and may be provided in any number. In addition, the shape of the knob-side claw portion 21 is not limited to the above-mentioned shape, and may be another shape.

[0016] As shown by the reference symbol B in FIG. 2, the other end of the operation knob 20 that is open and located on the lower side in the longitudinal direction is engaged with the end of the case 30. At this time, the thickness of the side wall of the other end of the operation knob 20 is formed thinner than other parts, and the other end is arranged to cover the outer periphery of the end of the case 30. That is, the side wall of the other end of the operation knob 20 and the side wall of the end of the case 30 are arranged to overlap. This improves the sealing property at the connection point between the operation knob 20 and the case 30, and the waterproof and dustproof effect of the lever switch can be improved. This also blocks the connection point between the operation knob 20 and the case 30, and prevents the internal configuration from being exposed to the outside. In the example of FIG. 2, the other end of the operation knob 20 is arranged to cover the outside of the end of the case 30, but conversely, the end of the case 30 may be arranged to cover the outside of the other end of the operation knob 20.

[0017] The case 30 is formed of a member having a ring-shaped side wall that extends from the vicinity of the other end of the above-mentioned operation knob 20 along the axial direction of the shaft 10 and has a predetermined length, and has an inner diameter larger than the diameter of the shaft 10. In this embodiment, the case 30 is formed in a substantially cylindrical shape having an inner diameter substantially the same as that of the above-mentioned operation knob 20, and one end of the case 30 in the longitudinal direction located on the upper side of FIG. 2 is opened and engages with the other end of the operation knob 20 as indicated by the symbol A. Specifically, the thickness of the side wall of one end of the case 30 is formed thinner than other portions, and is disposed so as to be located inside the other end of the shaft 10 as described above. That is, as described above, the side wall of the other end of the operation knob 20 and the side wall of the end of the case 30 are disposed so as to overlap each other.

[0018] Next, the internal structure of the lever switch will be described. FIG. 3 is a diagram showing the internal structure of the lever switch shown in FIG. 1B with the operation knob 20 and case 30 removed. The lever switch includes the above-mentioned shaft 10, button switch 40, and holder 50 as the internal structure. FIG. 4 is a diagram showing the structure of the shaft 10, and FIG. 5 is a cross-sectional view of the shaft 10 along the axial direction of the shaft 10 taken along line AA shown in FIG. 4. FIG. 6 is a diagram showing the structure of the holder 50. FIG. 7 is a cross-sectional view showing the state when the shaft 10 equipped with the button switch 40, the operation knob 20, and the holder 50 are assembled, and FIG. 8 is a cross-sectional view showing the structure after assembly. Each structure and assembly operation will be described below.

[0019] The shaft 10 is formed of a cylindrical shaft member having a predetermined length and a predetermined diameter. The shaft 10 is formed so that the diameters of one end located on the upper side of Fig. 4 are different from the diameter of the other end located on the lower side. Specifically, the one end of the shaft 10 is formed in a generally cylindrical shape having a larger diameter than the other end, and constitutes a mounting portion 10A to which a button switch 40 and an operation knob 20 are mounted, as described below. The other end of the shaft 10 is formed in a generally cylindrical rod-like body having a smaller diameter than the one end.

[0020] As shown in Fig. 3, a button switch 40 is attached to an end face formed at one end of the mounting part 10A on the upper side in Fig. 4, and a contact member (not shown) is also provided for detecting the pressing operation of the button switch 40. The button switch 40 is configured to move in the pressing direction when pressed along the axial direction, and further detects the movement in the pressing direction, thereby detecting the pressing operation.

[0021] The mounting part 10A is inserted into the annular part of the operation knob 20 from the open end of the operation knob 20, so that the operation knob 20 is mounted on the mounting part 10A. When the operation knob 20 is mounted, as shown in Figs. 7 and 8, the side wall of the operation knob 20 is located on the side surface of the mounting part 10A, which is substantially cylindrical, and in particular, the knob-side claw portion 21 formed on the operation knob 20 is located. Accordingly, the side surface of the mounting part 10A is provided with a claw portion 11 that protrudes further outward, that is, toward the side wall of the mounted operation knob 20. The claw portions 11 are provided at two pairs of positions on opposite sides of the axis of the side surface of the substantially cylindrical mounting part 10A, corresponding to the knob-side claw portion 21 of the operation knob 20 described above. That is, the claw portions 11 are provided symmetrically with respect to the axis of the shaft 10. As shown in the cross-sectional view of FIG. 5, the claw portions 11 are formed at an angle such that the protruding height gradually increases from one end side of the shaft 10 toward the other end side.

[0022] As shown in the cross-sectional view of FIG. 5, the mounting part 10A has a gap 12 formed on the inner side of the claw 11, that is, on the axial center side opposite to the protruding direction of the claw 11. At this time, the end face located on the other end side of the mounting part 10A is a stepped surface formed by a large change in diameter with respect to the rod-shaped body on the other end side at a predetermined length position of the shaft 10 as described above, and the stepped surface is formed in an annular shape facing the other end side. The above-mentioned gap 12 opens from the end face, which is the annular stepped surface of the mounting part 10A, toward the other end side, and is formed in a groove shape having a predetermined width and depth from the end face side toward the one end side along the axial direction. In this way, since the gap 12 is formed on the axial center side, which is the inner side of the claw 11, the member forming the claw 11 is allowed to bend and move within the gap 12. Since the gaps 12 are formed corresponding to the above-mentioned claws 11, they are provided at two pairs of positions located on opposite sides of the axis of the side surface of the mounting part 10A, which is substantially cylindrical. In other words, the gaps 12 are provided symmetrically with respect to the axis of the shaft 10. Note that, in FIG. 5, as an example, a case where two claws 11 and gaps 12 are formed in the mounting part 10A is illustrated, but the claws 11 and gaps may be provided at any positions and in any number depending on the positions and number of the above-mentioned knob-side claws 11. In addition, the shapes of the claws 11 and gaps 12 are not limited to the above-mentioned shapes, and may be other shapes.

[0023] 3, the holder 50 is attached to the mounting part 10A from the other end side where the axial member of the shaft 10 is located. Accordingly, a small protrusion 13 that protrudes further outward is provided on the side surface of the mounting part 10A, which is substantially cylindrical, as shown in FIG 4. The small protrusion 13 is formed to protrude lower than the above-mentioned claw portion 11, and is inserted into a hole formed in a fitting portion 52 provided on the holder 50, which will be described later.

[0024] As will be described later, the operation knob 20 and the holder 50 mounted on the mounting portion 10A rotate together with the mounting portion 10A itself, that is, the shaft 10, about the axis of the shaft 10 while mounted.

[0025] The holder 50 is formed of an annular member having an insertion hole into which the above-mentioned shaft 10 is inserted. The end face of the holder 50 on the one end side located on the upper side of FIG. 6 has a convex portion 51 that protrudes further toward the one end side along the axial direction. The convex portion 51 is inserted into the void portion 12 formed in the mounting portion 10A of the above-mentioned shaft. For this reason, the convex portions 51 are provided at two pairs of positions that are located opposite each other across the axis, corresponding to the formation positions of the void portion 12. That is, the convex portions 51 are provided symmetrically with respect to the axis. In this way, a plurality of pairs of the void portion 12 and the convex portion 51 inserted into the void portion 12 are provided, and the plurality of pairs are provided symmetrically with respect to the axis of the shaft 10. The convex portion 51 is formed in a substantially plate-like shape having a thickness corresponding to the width of the void portion 12, and is formed to protrude to a length corresponding to the depth of the void portion 12. As described below, the protrusions 51 are inserted into the gaps 12 to fill the gaps 12 and prevent the member forming the claws 11 from bending and moving toward the gaps 12. The positions and number of the protrusions 51 are not limited to those described above, and they may be provided in any positions and in any number depending on the positions and number of the gaps 12. The shape of the protrusions 51 is not limited to the above, and may be another shape.

[0026] 6, a fitting portion 52 into which the small protrusion 13 formed on the mounting portion 10A of the shaft 10 is fitted is provided on the side surface of the holder 50. The fitting portion 52 is formed in an annular shape so as to form a hole into which the small protrusion 13 is inserted, and a plurality of fitting portions are provided corresponding to the number of the small protrusions 13.

[0027] 6, a terminal 53 is provided on the other end of the holder 50. At this time, since the holder 50 is attached to the shaft 10 so as to rotate together with the shaft 10 and the operation knob 20 attached to the shaft 10, the holder 50 rotates in accordance with the rotation of the operation knob 20, and the terminal 53 is used to detect such rotation.

[0028] The shaft 10 equipped with the button switch 40 configured as above, the operation knob 20, and the holder 50 are assembled as follows. First, as shown by the arrow Y11 in FIG. 7, the operation knob 20 is attached from one end of the shaft 10 along the axial direction. Specifically, the mounting portion 10A (see FIG. 4) located at one end of the shaft 10 is inserted to a predetermined depth into the annular portion of the operation knob 20, and the operation knob 20 is attached to the mounting portion 10A. During this insertion, the knob-side claw portion 21 provided on the inner surface of the side wall of the operation knob 20 comes into contact with the claw portion 11 formed to protrude from the side surface of the mounting portion 10A of the shaft 10, and the knob-side claw portion 21 presses the claw portion 11 from the outer periphery toward the axial center. At this time, the member forming the pressed claw portion 11 flexes and moves into the gap portion 12 formed on the axial center side of the shaft 10, and the knob-side claw portion 21 of the operation knob 20 climbs over the claw portion 11 of the shaft 10, and the knob-side claw portion 21 and the claw portion 11 are engaged with each other as shown in Fig. 8. At this time, since the abutment points of the claw portion 11 and the knob-side claw portion 21 are formed to be inclined relative to each other, the knob-side claw portion 21 smoothly climbs over the claw portion 11 of the shaft 10. As a result, the mounting portion 10A of the shaft 10 can be inserted into the operation knob 20 to a predetermined depth, and the operation knob 20 can be mounted on the mounting portion 10A of the shaft 10.

[0029] Next, as shown by the arrow Y12 in FIG. 7, the holder 50 is attached to the mounting portion 10A of the shaft 10 to which the operation knob 20 is attached as described above (see FIG. 4) from the other end side of the shaft 10 along the axial direction. Specifically, the holder 50 is moved relative to the other end face of the mounting portion 10A, and the convex portion 51 formed on the end face on one end side of the holder 50 is inserted into the gap portion 12 opening on the other end face of the mounting portion 10A. As a result, the convex portion 51 fills the gap portion 12, and the member forming the claw portion 11 is prevented from bending and moving toward the gap portion 12. As a result, the knob-side claw portion 21 and the claw portion 11 are firmly engaged, and the shaft 10 and the operation knob 20 can be reliably fixed. Then, the convex portion 51 of the holder 50 is inserted to a predetermined depth in the gap portion 12, and the fitting portion 52 provided on the holder 50 fits into the small protrusion 13 formed on the mounting portion 10A of the shaft. This allows the holder 50 to be attached to the attachment portion 10A of the shaft 10.

[0030] Thereafter, the other end of the shaft 10 is inserted from one end of the case 30, and the other end of the operation knob 20 attached to the shaft 10 is engaged with one end of the case 30. This allows the lever switch to be assembled as shown in FIG 1B.

[0031] When disassembling the lever switch assembled as described above for maintenance, the above steps are reversed. First, the case 30 is removed, and the holder 50 is pulled out along the axial direction of the shaft 10 toward the other end, thereby removing the holder 50 from the mounting part 10A of the shaft 10. At this time, the fitting part 52 of the holder 50 is operated so as to open from the axial center side toward the outside, whereby the fitting state between the fitting part 52 of the holder 50 and the small protrusion 13 of the mounting part 10A can be easily released, and the holder 50 can be easily removed from the mounting part 10A of the shaft 10. Next, the operation knob 20 is removed from the mounting part 10A of the shaft 10 by pulling it out along the axial direction of the shaft 10 toward one end. At this time, the convex part 51 of the holder 50 has already been removed from the gap part 12 of the mounting part 10A, so that the gap part 12 is hollow, and the claw part 11 is allowed to bend toward the gap part 12. Therefore, for example, by pressing the claw portion 11 from the outside toward the axial center, causing the claw portion 11 to bend and move toward the gap portion 12, the engagement between the claw portion 11 and the knob-side claw portion 21 can be easily released, and the operating knob 20 can be easily removed from the mounting portion 10A of the shaft 10.

[0032] As described above, the lever switch according to the present disclosure prevents an increase in the number of parts, can be easily assembled, and can also be easily disassembled.
