Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a composite switch for mounting a boot for an operating lever on a switch case with one touch and for preventing the operating lever from being attached on the movable plate with one touch.

[0002]

[Prior art]

 Conventionally, as a lever device in which a boot is arranged on an operation lever, for example, there is a technique disclosed in Japanese Utility Model Laid-Open No. 1-106923. The boot is made of a rubber member made of elastic material and has a substantially skirt shape. The boot has one open end attached to the body via a boot attaching member, and the other open end fitted into a groove provided around the operation lever. The boot is deformed by operating the operating lever.

Further, as a conventional technique of this type, for example, there is a lever device disclosed in Japanese Utility Model Publication No. 2-36190. In this lever device, a protrusion formed at the tip of the shaft portion of the lever is fitted into the fitting groove portion and the retaining portion of the bracket by a so-called one-touch method.

[0004]

[Problems to be solved by the device]

 Since the above-mentioned conventional lever device has the boot mounting member and the elastic boot, the number of parts is large and the cost is increased. Since the boots are manufactured according to the shape of the operation lever to be attached, there is a problem in that there are many kinds as well as the kinds of operation levers. Further, some lever devices include those with boots and those without boots. The operating lever of the lever device equipped with boots must be provided with a groove around the operating lever in order to install the boot. Therefore, even if the lever devices have the same structure, two types of operation levers are required, such as the presence or absence of a groove depending on the presence or absence of boots. Further, when the conventional boot is attached to or detached from the lever device, the operation lever is detached from the lever device, and then the boot is inserted into the operation lever, so that the attaching and detaching work of the boot is inconvenient.

Further, in the above-mentioned conventional lever device, the lever shaft is pivotally supported in the vertical direction by axially engaging the shaft portion of the lever with the retaining portion formed of the elastic piece. When the lever is strongly operated in the up-down direction or the front-back direction, the retaining portion may be curved and the shaft portion may come off the retaining portion, and the lever may be detached from the bracket.

[0006]

[Means for Solving the Problems]

 The structure of the composite switch according to the present invention includes an operation lever rotatably mounted on a switch case, a column cover having a lever insertion hole through which the operation lever penetrates, and the switch disposed in the column cover. In a composite switch including a case and a boot that closes between the switch case and the lever insertion hole, the boot is detachably locked to the switch case, and a peripheral edge portion of the lever insertion hole of the column cover is provided. By providing the boot having the opening that opens in a substantially trumpet shape toward the front, the above-mentioned problems of the conventional technology are solved.

Further, the structure of the composite switch according to the present invention comprises an operation lever having a shaft portion formed on both side surfaces of a base end portion, a movable plate having two opposing arm portions pivotally supporting the shaft portion, In a composite switch including a switch that rotatably supports the movable plate, a fall prevention wall is formed on the switch case at a position facing each of the two arm portions of the movable plate, and an operation lever is provided. It is intended to eliminate falling off from the switch case.

The arm portion 4d having the claw 4e and the shaft supporting portion 4b are not limited to the shapes described above. For example, the support portion 4b may be formed in the arm portion 4d as a hole to be fitted to the shaft portion 1b, and the side wall of the opening portion 4a, the shaft support portion 4b, and the claw 4e may not be provided.

The switch case 5 is provided with a substantially arcuate drop-off prevention wall 5b outside and opposite to the arm 4d of the movable plate 4. The switch case 5 has ears 5c formed on both side surfaces, and the ears 5c are fitted into the screw fastening portions 8a of the base 8 and fastened with screws. The switch case 5 has a window portion 5d for allowing the operation lever 1 to project outside the switch case 5. The switch case 5 has an engaging portion 5e on the outer side of the window 5d, into which the protruding piece 9a of the boot 9 is fitted. The engaging portion 5e has a tubular shape, and has a hole 5f formed in the side wall, into which the claw 9b of the protruding piece 9a is fitted. The engaging portion 5e is not limited to the tubular shape having the hole 5f, and may be, for example, a hook or the like with which the boot 9 is locked.

The lid 6 has a shaft hole 6 a into which the support shaft 4 g of the movable plate 4 is fitted, and a long hole 6 b into which the support shaft 11 a of the cancel cam 11 is fitted. The lid 6 has, on its lower surface, convex portions 6c for holding both ends of the leaf spring 12 engaged with the cancel cam 11.

The boot 9 hides the switch case 5, the base 8 and the like so that they cannot be seen when the lever insertion hole 10a of the column cover 10 is looked into from the outside. The boot 9 is made of the same resin material as that of the operation lever 1 or the switch case 5. The boot 9 has a substantially trumpet shape and is arranged such that the tip of the opening 9c is aligned with the inner peripheral edge of the lever insertion hole 10a of the column cover 10. The boot 9 has a cutout portion 9d on the lower surface for allowing the operating lever 1 to pass therethrough. Reference numeral 9e is a positioning hole that fits into the convex portion 5g formed on the switch case 5.

The column cover 10 is formed by mating two substantially symmetrical members, and surrounds the base 8 on which the switch case 5 and the like are mounted.

The cancel cam 11 has a support shaft 11 a on the lower surface arranged in the recess 4 h of the movable platen 4, and a support shaft 11 a on the upper surface axially fitted in the elongated hole 6 b of the lid 6. The leaf spring 12 is a spring that automatically returns the cancel cam 11 to the original position.

Reference numeral 13 denotes a mover that can linearly move in the direction of the operation lever 1, and is interposed between the movable plate 4 and the lid 6. The mover 13 has a hole 13a on its side surface in a direction perpendicular to the direction of linear movement. The movable element 13 has a spring 14 and a steel ball 15 inserted into the hole 13a, and the steel ball 15 is pressed against the locking groove 4i to be locked at a predetermined position on the movable platen 4. There is. The mover 13 forms an abutting portion 13b that abuts when the cancel cam 11 rotates.

The structure of the composite switch according to the present invention is as described above, and the assembly procedure will be described in detail below.

The operation lever 1 is inserted laterally into the opening 4 a of the movable plate 4 via the steel ball 2 and the spring 3. The steel ball 2 is pressed against the moderation groove 4f. The shaft portions 1b, 1b press the claws 4e, 4e, expand the two arm portions 4d, 4d to both sides, and insert them into the holes 4c, 4c of the shaft support portions 4b, 4b. It is clamped between 4 d.

The mover 13 having the spring 14 and the steel ball 15 inserted therein is installed on the movable platen 4. Moderation pins 7 and 7 are mounted on the movable plate 4. Insert the movable plate 4 into the switch case 5 from above. At this time, the moderation pins 7 and 7 are pressed against the moderation portions 5a and 5a to support the movable platen 4. The two arm portions 4d, 4d are arranged inside the two captive walls 5b, 5b.

The leaf spring 12 is inserted into the cancel cam 11. Both ends of the leaf spring 12 are locked between the convex portions 6c of the lid 6 and the support shaft 11a of the cancel cam 11 is inserted into the elongated hole 6b. The lid 6 is fitted from one side of the switch case 5.

The projecting pieces 9a, 9a of the boot 9 are fitted into the cylindrical engaging portions 5e, 5e from above the switch case 5, and the positioning holes 9e, 9e are fitted in the convex portions 5g, 5g. The claws 9b, 9b are engaged with the holes 5f, 5f, and the boot 9 is attached to the switch case 5 with a so-called one-touch operation. The operating lever 1 is located substantially in the center of the opening 9c of the boot 9. Since the boot 9 has a cutout portion 9d through which the operating lever 1 is inserted, the boot 9 can be easily attached to and detached from the switch case 5 to which the operating lever 1 is assembled.

Further, since the boot 9 has an opening 9c which is opened in a substantially trumpet shape toward the handle side of the operation lever 1, it can be assembled without contacting the operation lever 1. The operating lever 1 does not need the boot mounting groove that is provided around the conventional operating lever. Conventionally, depending on the presence or absence of the boot 9, the boot 9 can be provided with one type of two types of operation levers 1 with and without a groove. The boot 9 can be used for all kinds of operation levers 1 regardless of the shape and size of the operation lever 1. Further, since the boot 9 is directly attached to the switch case 5 without using the conventional boot attaching member, the number of parts and the number of assembling steps can be reduced.

The movers 16, 17, and 18 and the pole board 19 are fitted to the lower surface of the switch case 5. The switch case 5 is slid in from the lateral direction and fixed to the base 8 with screws. The two column covers 10 facing each other are combined to surround and fix the base 8.

Next, the operation of the structure of the composite switch according to the present invention will be described in detail.

The lever insertion hole 10a can be seen when looking in the direction of the column cover 10 from the door side of the front seat in the interior of the automobile. The boot 9 having an opening 9c is found inside the lever insertion hole 10a. However, the switch base 5 and the base 8 are hidden and invisible. Then, as an observer, the assembly configuration of the composite switch is simplified. Further, the boot 9 is installed in conformity with the lever insertion hole 10a and has a form in which the wall surface portion is provided to prevent dust and the like from entering the column cover 10 and the switch case 5.

When the operating lever 1 is operated in the upward arrow A direction or the downward arrow B direction, the operating lever 1 rotates about the shaft portion 1b, and this composite switch is, for example, a dimmer switch and a passing switch. Works. When the operating lever 1 is operated in the rightward arrow C direction or the leftward D direction, the operating lever 1 and the movable platen 4 rotate about the support shaft 4g, and this composite switch is, for example, right or left. The turn signal operates to activate the turn signal.

When the operating lever 1 is operated in the directions of arrows A, B, C, and D, the operating lever 1 does not come into contact with the boot 9 because the boot 9 has a so-called trumpet shape. Therefore, the boot 9 can be applied to all the operating levers 1 regardless of the diameter of the operating lever 1 and the number of parts can be reduced. Since the shape of the boot 9 itself does not change even when the operating lever 1 is operated, it is possible to manufacture a composite switch having a high durability with a hard resin in place of the conventional expandable boot.

When the operation lever 1 is operated in the right arrow C direction or the left direction D direction, the movable plate 7 rotates about the support shaft 4g. The two arm portions 4d, 4d rotate inside the fall prevention walls 5b, 5b.

The shaft portions 1b and 1b of the operating lever 1 are inserted into the shaft support portions 4b and 4b, and are rotatably held by the two arm portions 4d and 4d and the claws 4e and 4e. When an unnecessary operation force or an excessive force is applied to the operation lever 1 in a direction different from the operation direction, the two arm portions 4d, 4d are pushed by the shaft portions 1b, 1b and are deformed outward. When the two arm portions 4d or 4d are deformed outward by a predetermined amount or more, the two arm portions 4d or 4d come into contact with the fall prevention wall 5b or 5b of the switch case 5, so that the movement of the arm portion 4d or 4d is prevented by the fall prevention wall 5b or 5b. The movement of the shaft portions 1b, 1b is regulated and the arm portions 4d, 4d are prevented from coming off the shaft supporting portions 4b, 4b. In the operation lever 1, the base end portion 1 a does not fall off the movable platen 4.

[Effect of device]

 In the structure of the composite switch according to the present invention, the boot can be easily attached to and detached from the switch case by a simple means without removing the operating lever from the switch case, so that the boot can be easily attached. Since the boot can be installed in the switch case without requiring any intervening parts, the number of parts and the number of assembling steps can be reduced. Since the boot can be attached to the composite switch without forming a boot attachment groove on the operation lever, the operation lever can be commonly used for the composite switch having no boot. Since the boot has an opening that is opened in a substantially trumpet shape and does not come into contact with the operation lever when the operation lever is operated, the boot is not affected by the shape and size of the operation lever. It can be used for all operating levers. Moreover, since the boot does not change its shape at all times, it can be molded with a resin material, which secures the strength of the composite switch and improves the durability.

In addition, in the structure of the composite switch according to the present invention, since the fall prevention wall is formed in the switch case and the facing position of the two arms that pivotally support the shaft of the operation lever, an external force is applied to the operation lever. Also, the movement of the arm portion is restricted, the shaft portion is prevented from coming off from the two arm portions, and the operation lever does not come off from the switch case.
