"Prior Art" When the operator protruding from the tubular case is pushed to the first position, the movable body is held in engagement with the tubular case at the first position in the tubular case. When the first switch operation is performed and the operator is further pushed to the second position, the movable body is engaged with and held by the tubular case at the second position in the tubular case, and the second switch operation is performed. The push-type switch that is used is used.

For example, in a vehicle-mounted air conditioner, this type of push-type switch can be used as a switch for switching between normal operation and economic operation of the air conditioner. In this case,
Display of normal operation and economic operation of the air conditioner is provided side by side on the protruding end surface of the operator, and the air conditioner is set to the normal operation state by pushing the operator of the push-type switch to the first position, By pushing the operating element to the second position, the air conditioner is set to the economical operating state. When the operating element is pushed to the first and second positions respectively, the display of the protruding end surface of the operating element is switched and illuminated by, for example, a lamp.

In this type of push-type switch, a so-called heart cam type structure is adopted in order to engage and hold the moving body in the cylindrical case at the first and second positions, respectively, by the first and second pushing of the operator. Has been done. In the structure of the heart cam system, a sliding surface is formed on the moving body that moves in the cylindrical case, and a contact portion formed at the end of the hook spring attached between the cylindrical case and the moving body moves on the sliding surface. It is configured to slide and move to hold the engagement.

FIG. 2 shows the configuration of such a push-type switch using a conventionally proposed heart-cam type structure.
A movable body (12) is movably provided in the cylindrical case (11). The protruding portion of the moving body 12 from the cylindrical case 11 serves as an operator 13. A biasing force is applied to the moving body 12 by a spring 14 mounted between the moving body 12 and the tubular case 11 in a direction in which the operator 13 projects from the tubular case 11.

A sliding surface on which the contact part of the hook spring slides in contact with the moving body 12.
17 are formed. A hook spring 15 is attached between the tubular case 11 and the moving body 12. One end of the hook spring 15 is fixed to the tubular case 11, and this fixed portion is wound in a coil shape, and the hook spring 15 has a moving direction of the moving body 12, that is, the tubular case 11 in FIG. A biasing force is applied in a direction perpendicular to the axis of the. See also
The tip of 15 receives a force in the direction of lightly contacting the sliding surface 17. The tip of the hook spring 15 is bent toward the sliding surface 17,
The tip of the bent portion serves as a contact portion 18 that contacts the sliding surface 17.

First and second plate-shaped heart-shaped bodies 21 and 22 are formed on the sliding surface 17 so as to project therefrom. The heart-shaped bodies 21 and 22 are respectively formed with first and second concave portions 23 and 24 which are recessed in a direction opposite to a direction in which the operator 13 is projected from the cylindrical case 11.

A projection 26 is formed on the sliding surface 17 that has a side surface facing the bias direction X side of the hook spring 15 of the first and second heart-shaped bodies 21 and 22 and having a side surface substantially parallel to this side surface. This protrusion
The projecting length of 26 is set to be almost the same as the projecting length of the first and second heart-shaped bodies 21 and 22.

On the other hand, adjacent to the sliding surface 17, the first and second heart-shaped bodies
A contact piece mounting surface 30 is formed so as to project from the sliding surface 17 more than 21,22. The contact piece mounting surface 30 is formed with contact piece mounting holes 32 and 33.

Opposite the second concave portion 24 of the second heart-shaped body 22,
35 is formed, and the protruding length of the projection 35 from the sliding surface 17 is set to be substantially the same as that of the first and second heart-shaped bodies 21 and 22. The side surface of the protrusion 35 facing the second recess 24 is formed substantially parallel to the side surface of the second recess 24. The second heart-shaped body 22 faces the side surface of the contact piece attachment surface 30 side, and the side surface faces the side surfaces of the second and first heart-shaped bodies 21 and 22 substantially parallel to each other. Protrusions 38 having substantially the same protruding length as the heart-shaped members 21, 22 are formed. Further, a wall body 40 is formed between the side surfaces of the projection body 38 and the contact piece mounting surface 30.

FIG. 3 shows a sliding surface 17 portion of a push-type switch of this type which has been conventionally proposed. The first heart-shaped body 21 is provided between the sliding start point of the hook spring 15 and the first concave portion 23. Along the side surface, a first path l ₁ along which the contact portion 18 of the hook spring 15 moves is formed as shown by the dotted line in FIG. This first
The path l ₁ is formed obliquely in the pushing direction of the operator 13 so as to prevent the contact portion 18 of the hook spring 15 from being biased in the arrow X direction.

Similarly, a second path l ₂ is formed between the first concave portion 23 and the second concave portion 24 along the side surface of the second heart-shaped body 22 as shown by the alternate long and short dash line in FIG. ing. The second path l ₂ is also formed obliquely in the pushing direction of the operating element 13 so as to prevent the contact portion 18 of the hook spring 15 from being biased in the X direction. A third path l ₃ is formed between the second concave portion 24 of the second heart-shaped body 22 and the starting end of the first path, as indicated by a chain double-dashed line in FIG.

When the operator 13 is pushed into the cylindrical case 11 and the first pushing operation is performed, the contact portion 18 of the hook spring 15 moves on the sliding surface 17 along the first course l ₁ to move the first path. Reach the end point A of l ₁ . At the end point A, the blocking of the side surface of the first heart-shaped body 21 in the biasing direction is released, so that the contact portion 18 is biased and moved in the arrow X direction, and is located in the first recess 23. At this time, the push-in to the operating element 13 has been released, the contact portion 18 is stabilized in the first recess 23, and the moving body 12 is engaged and held at this first position with respect to the tubular case 11.

When the operator pushes the operator 13 a second time from the first position, the contact portion 18 moves in the direction of the second heart-shaped body 22 on the peripheral surface of the first recess. At the end point B of the first concave portion 23, the contact portion 18 is released from the blocking direction, so that the contact portion 18 receives the biasing force, and the starting point C of the second path l _{2 on} the side surface of the second heart-shaped body 22. Transfer to. Following the pushing, the contact portion 18 moves along the second path l ₂ , and when it reaches the end point D ₂ , the blocking in the deviation direction is released and the contact portion 18 receives a biasing force in the X direction, and at this position the second pushing When is released, it is stably positioned in the second recess 24. In this state, the moving body 12 is engaged and held in the cylindrical case 11 at the second position.

When the operator 13 is pushed in from the second position, the contact portion 18 reaches the end point E along the side surface of the second recess 24, and the blocking of the bias is released at this position. X
The third path l ₃ on the side surface of the protrusion 26 due to the biasing force in the direction
To the starting point F of. At this position, since the pushing force against the operator 13 is released, the contact portion 18 is returned to the start point of sliding by the biasing force of the spring 14, and the protrusion of the operator 13 from the cylindrical case 11 is maximized. Return to the original position.

In the conventionally proposed push-type switch, the wall body 40 is formed as shown in FIG. 3, and even if the first pushing force is too strong, the contact portion 18 does not slide much beyond the end point A. When it is blocked and the push is released, it becomes the first due to the biasing force.
It is configured so as to be stably positioned in the recess 23. However, the feeling of pushing is subtle, and if the pushing is continued while it is in contact with the wall 40, the hook spring 15 may be deformed and damaged. Therefore, when the pushing-in is continued further in a state of being in contact with the wall body 40 by a predetermined amount or more, the contact portion 18 is allowed to move over the wall body 40, and the overcoming of the wall body 40 is performed through the operator 13. It has a structure that can be sensed by touch.

The contact portion 18 that has crossed over the wall 40 has a dotted arrow P in FIG.
It is located at n through the route shown by. Contact part located at n
By releasing the pushing force, 18 receives the biasing force in the direction of the arrow X and is settled in the second recess 24 by the biasing force of the spring 14.

However, in this conventionally proposed push-type switch, the contact portion 18 is eccentrically moved to the first recessed portion 23 by releasing the pushing force with a pushing force below a predetermined value, and the contact portion 18 is moved to the wall body when the pushing force is more than a predetermined value. 2nd to smoothly overcome 40
It is quite difficult to make the structure in which it is biased to the concave portion 24 and to get over the wall body 40 as a reliable feel.

That is, depending on the configuration of the wall body 40, the contact portion 18 may not ride over the wall body 40 and may be located on the projection body 38 as indicated by k in FIG. In this case, the contact portion 18 receives a strong biasing force in the direction of the arrow X, so that the contact portion 18 is located at m along the path shown by the dotted line t. In such a state, the contact portion 18 cannot stably settle in either of the first and second recesses 23, 24, and returns to the starting point of sliding through the _third path l _3. I will end up. That is, in this state, the moving body 12 is not engaged and held with respect to the tubular case 11 at either the first or second position.

In order to prevent such a situation, the protrusion length or shape of the wall body 40 is set to the spring force of the hook spring 15, the shape of the contact portion 18, the shape of the first path l ₁ , the protrusion length of the protrusion 38, and It is necessary to set the optimum conditions according to the shape and the biasing force of the spring 14. Generally, if the protrusion length of the wall 40 is small, the feel during operation is not sufficiently obtained, and if the protrusion length is increased, the protrusion
The likelihood of the contact 18 being located on the 38 is increased.

Therefore, as the shape of the wall body 40 taken along the line AA in FIG. 3, various shapes have been proposed, as shown in FIGS. 4 (A), (B), and (C). However, as a result of research by the inventors, each shape has advantages and disadvantages, and the optimum shape of the wall 40 is set by the spring force of the hook spring 15 and the contact portion 18.
It has been confirmed that it must be experimentally determined in consideration of a number of factors such as the shape of the first path l ₁ , the shape of the first path l ₁ , the shape of the protrusion 38, and the biasing force of the spring 14.

"Problems to be Solved by the Invention" In this invention, the contact portion 18 has first and second concave portions, which occur in the previously proposed push-type switch.
The purpose is to eliminate the situation where the robot cannot be positioned stably in either of the 23 and 24.

In order to achieve this object, the present invention introduces a stopper based on a completely new technical idea as a constituent element, and when the contact portion cannot be stably located in the first concave portion, the contact portion is always the first portion. A structure that is stably positioned in the concave portion of 2 is realized. According to the present invention, there is provided a push-type switch in which engagement holding of the movable body with respect to the tubular case at the second position is always realized even if the engagement holding is not performed at the first position.

[Structure of the Invention] In this invention, the movable body is attached to the cylindrical case so as to be biased in the direction of protruding from the cylindrical case, and the protruding portion of the movable body from the cylindrical case serves as an operator. When the operator is pushed in to the first pushing position, the moving body is engaged with and held by the tubular case at the first position, and when the operator is pushed further into the second pushing position, the moving body moves to the tubular state. Is retained in the second position with respect to the case. In the push-type switch of the present invention, the first and second switch operations are performed at these first and second positions, respectively.

A hook spring is attached between the tubular case and the moving body,
A sliding surface is formed on the moving body. The end of the spring is bent toward the sliding surface, and its tip is a contact portion that contacts the sliding surface. The contact portion of the hook spring is biased on the sliding surface by the spring biasing force in a direction perpendicular to the pushing direction of the operator.

From this, the sliding surface is projected with a gentler inclination than the right angle, and the first
Is formed obliquely in the pushing movement direction of the operator so as to prevent the contact portion from being displaced in the right-angled direction, and the end opposite to the pushing movement direction of the first passage is depressed in the pushing movement direction. A first recess is formed. A second path is formed on the sliding surface so as to project a gentler inclination than the right angle from the first concave portion obliquely in the pushing movement direction of the operator so as to bias the contact portion in the right angle direction. A second concave portion, which is recessed in the pushing movement direction, is formed at the end of the second path opposite to the pushing movement direction. A third path that extends from the second recess to near the other end of the first path is formed on the sliding surface so as to project therefrom.
A protrusion is provided on the sliding surface so as to face the first recess and the contact portion with a gap passing therethrough, and at least the surface of the protrusion facing the first recess of the first path is slidable. The contact portion is configured to be inclined more gently than the right angle with respect to the moving surface, and the contact portions are located in the first and second recesses at the first and second pushing positions, respectively.

In this invention, when the contact portion rides on the protrusion at a position in the vicinity of the first concave portion of the first path, and the contact portion is separated from the sliding surface by a predetermined distance, the back spring is prevented from being displaced more than a predetermined amount in the perpendicular direction. A stopper is provided in the cylindrical case. When the vicinity of the bent portion of the hook spring is in contact with this stopper and the contact portion is separated from the sliding surface by a predetermined distance, the contact portion is selected near the end of the second path when the stopper is further pushed. ing.

The contact portion of the hook spring is separated from the bottom surface of the first path by a predetermined distance in the vicinity of the first recess due to the first pushing of the operator, and the contact portion of the hook spring is not stably positioned in the first recess. Even if a strong biasing force is applied, the stopper is prevented from biasing the contact portion in a direction perpendicular to the predetermined amount or more. In this state, the contact portion is located on the sliding surface in the vicinity of the end position of the second path, so that the contact portion located on the sliding surface is biased to the second recess and the moving body is tubular. It is always engaged and held in the second position with respect to the case.

[Embodiment] The push-type switch of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, the same parts as those of the conventional proposal are designated by the same reference numerals, and the principle of the construction of the essential part of the embodiment of the push-type switch of the present invention is shown. An operator not shown is pushed in the arrow Y direction. When the operator is pushed, the moving body moves in the same direction, and the sliding surface 17 formed on the moving body moves in the arrow Y direction.

A taper T ₁ is formed on the side surface of the first heart-shaped body 21 which is formed on the sliding surface 17 and serves as the first path l ₁ , so that the inclination is gentler than the right angle with respect to the sliding surface 17. There is. On the side surface of the projection body 38 facing the first recess 23 of the first heart-shaped body 21, a taper T ₂ having an inclination gentler than the right angle with respect to the sliding surface 17 is also formed. A similar taper T ₃ is also formed on the side surface of the second heart-shaped body 22 which will be the second path l ₂ .

The contact portion 18 of the hook spring 15 causes the first and second paths l ₁ and
At l ₂ , due to the biasing force in the direction of arrow X in FIG.
The taper T ₁ and T ₃ move while being pressed against the side surface on which they are formed. Tapers T ₁ and T ₃ are formed in order to smoothly perform this movement without catching. As a result of actual measurement by the inventors, it has been confirmed that when the tapers T ₁ and T ₃ are set to have an inclination of 82 to 83 ° with respect to the sliding surface 17, the contact portion 18 slides smoothly.

Since the contact portion 18 is not stable in the first concave portion 23 due to the excessive pushing of the operator, and the contact portion 18 abuts against the side surface of the projection 38, the contact portion 18 is a butted portion. If so, the hook spring 15 may be deformed and damaged by being pushed. The taper T ₂ prevents such deformation and damage, and the contact portion 18 is positioned on the projection 38 via the side surface on which the taper T ₂ is formed when the pushing force of a predetermined amount or more continues. Act on. As a result of actual measurements by the inventors, it has been confirmed that an optimum result can be obtained when the inclination of the taper T ₂ is about 70 ° with respect to the sliding surface 17.

As the hook spring 15, in the embodiment, as shown in FIG. 6, one end of a spring wire having a wire diameter of 0.6 mm has a coil inner diameter of 0.8.
A coil spring was wound in a coil shape four times at right angles to the extension direction of the hook spring 15 so as to have a size of mm. The other end of the hook spring 15 was bent at a right angle to the extension direction in the direction opposite to the coil-shaped portion, and the bent length was 2.7 mm.

In this invention, when the contact portion 18 is separated from the plate surface of the sliding surface 17 by a predetermined distance in the vicinity of the first concave portion 23 of the first path l ₁ , the hook spring 15 has a right angle indicated by an arrow X in FIG. A stopper (48) for preventing deviation in a predetermined direction or more is provided in the cylindrical case (11).

That is, in the embodiment shown in FIG. 1, the stopper 48 is formed so as to project from the inner surface of the upper plate facing the sliding surface 17 of the tubular case 11 at a right angle to the sliding surface 17. Stopper 48
As shown in FIGS. 5 (A) and 5 (B), is formed in a substantially cylindrical shape, and a disk-shaped brim 50 is integrally formed on the end side of the cylinder, and a cylindrical shape is formed on the tip side of the brim 50. A taper 51 is formed on the peripheral surface so as to narrow the diameter toward the tip side.

The mounting position of the stopper 48 is selected so that the vicinity of the bent portion of the hook spring 15 is located near the end position of the second path l ₂ when the hook spring 15 is in contact with the stopper 48.

That is, the stopper 48 is provided with the first recess 23 as shown in FIG.
It is attached between a straight line P ₁ passing through the lowest position of the depression and parallel to the moving direction of the operator, and a straight line P ₂ passing through the lowest position of the depression of the second recess 24 and parallel to the moving direction of the operator. .
In the moving direction of the operator, if it is between the straight line P ₁ and the straight line P ₂ ,
It suffices that the contact portion 18 is at a position where it can come into contact with the hook spring 15 when the biasing force acts on the foot spring 15 at a predetermined distance from the sliding surface at the first path l ₁ position. In this case, the predetermined distance at which the contact portion 18 separates from the sliding surface 17 is approximately equal to the projection length of the projection 38 from the sliding surface 17.

The contact portion 18 was not stable in the first recess 23 due to excessive pushing of the operator, and moved so as to ride on the protrusion 38 at a predetermined distance from the sliding surface 17 in the vicinity of the end of the first path l ₁ . Consider the case. When the contact portion 18 is disengaged from the side surface of the protrusion 38, a biasing force acts on the hook spring 15 in the X direction in FIG. 1, and the hook spring 15 moves in the X direction by this biasing force.

In this device, there is a stopper 48, so
The vicinity of the bent portion of 15 comes into contact with the stopper 48 and further bias is prevented. Since the mounting position of the stopper 48 is selected between the straight lines P ₁ and P ₂ described above, the contact portion 18 is located on the sliding surface 17 near the end of the second path l ₂ when further pushing is performed. .

In this situation, the contact between the hook spring 15 and the stopper 48 is released, and the hook spring 15 is provided between the X-direction biasing force and the tubular case and the moving body, and is moved by the biasing force of the spring (not shown). It is stably held in the second recess 24.

Select the protrusion length of the protrusion 38 and the inclination of the taper T ₂ so that the touch of the contact portion 18 over the protrusion 38 can be set so that the operator's hand can feel the optimum feel through the operator. Can be done. If the operator obtains this feel and releases the pushing of the operator after a minute time, the contact portion 18 becomes the second concave portion.
It will be located in a stable position on 24.

A taper 51 is formed on the peripheral surface of the stopper 48 as shown in FIG. By changing the inclination of the taper 51, the contact portion 18 of the hook spring 15 is accurately positioned near the end of the second path during the stopper operation, and the second recess 24
Adjustment for stable engagement position can be performed.

However, according to the result of actual measurement by the inventors, if the taper 51 is formed at about 80 ° with respect to the plate surface of the collar 50, the hook spring is pushed by pushing the operation member without performing any special fine adjustment. It has been confirmed that the contact portion 18 of 15 can be stably positioned in the second recess 24.

The push-type switch of the present invention is used, for example, as a switch for operating an air conditioner for a vehicle. As shown in FIG. 7, fixed contacts B ₁₁ , B ₁₂ ... B ₂₁ , B ₂₂ ... Of the switch are arranged on the inner edge so as to project from the upper lid 11-U of the cylindrical case 11. A contact piece mounting surface 30 is formed adjacent to the sliding surface 17 on the moving body 12, and the movable contact pieces F ₁ and F ₂ are fixed to the contact piece mounting surface 30 by the mounting holes 32 and 33.

The example shown in FIG. 7 has a configuration in which the operator 13 is fitted and fixed to the protruding portion of the tubular body 11 of the moving body 12. In FIG. 7, as shown in a state in which the operator 13 is removed, the cylindrical inside of the moving body 12 is vertically divided into two parts by the partition wall 50 on the projecting side from the cylindrical case 11.

An elastic light shield 52 is attached to the lower region divided by the partition wall 50 in parallel to the partition wall 50 with the end of the moving body 12 in the moving direction as a free end. On the other hand, an inclined guide body 53 is attached to the tubular case 11, and when the operator 13 is pushed in, the free end of the elastic light shield 52 rides on the inclined guide body 53.

The lamp 56 is mounted so as to be located inside the tubular portion of the moving body 12. The state in which the operator 13 is projected to the maximum extent from the cylindrical case 11 is the state in which the power supply to the air conditioner is cut off. When the operator 13 is pushed in from this state to engage and hold the moving body 12 in the first position with respect to the tubular case 11, the moving contact pieces F ₁ and F ₂ move to the fixed contacts B ₁₁ , B ₁₂ and B ₂₁ , B ₂₂
Short circuit between them.

In this state, the lamp 56 is turned on, and the power supply voltage is supplied to the air conditioner so that the air conditioner is driven in the normal operation state.

In this state, the elastic light shield 52 attached to the moving body 12
No elastic displacement has yet occurred on the partition wall 50 side, the illumination light from the lamp 56 is incident on the upper and lower sides of the partition wall 50, and the indications 60-1 and 60-2 attached to the protruding end surface of the operator 13 are Both are brightly illuminated.

Push in the operating element 13 and move the moving body 12
Is held in the second position, the movable contact pieces F ₁ and F ₂ short-circuit the fixed contacts B ₁₃ , B ₁₄ and B ₂₃ , B ₂₄ . In this state, the lighting of the lamp 56 is maintained, and the power supply voltage is supplied to the air conditioner so that the air conditioner is driven in the economical operation mode.

In this state, due to the movement of the moving body 12, the free end of the elastic light-shielding body 52 completely riding on the inclined guide body 53 is elastically displaced toward the partition wall 50 side, and the optical path below the partition wall 50 is blocked. Therefore, only the display 60-2 is brightly illuminated on the protruding end surface of the operator 13, and it is displayed that the air conditioner is operating in the economical operation mode.

As described above, when the push-type switch of the present invention is applied to the air conditioner of a vehicle, even if the operator 13 is pushed too hard, the moving body 12 is in the cylindrical case at the second position.
Since it is always engaged and held with respect to 11, the air conditioner device is reliably driven at least in the economical driving operation state.

In this device, the push-in of the operator is too strong and
In a state where the contact portion 18 of 15 is not stably positioned in the first recess 23, the operator can feel the operator through the operator 13, and
In the state where the pushed contact portion 18 is disengaged from the stopper 48, it is located near the end of the second path, and the contact portion is stably positioned in the second recess 24 by the biasing force.

It is possible to reliably prevent a situation in which the hook spring 15 is not deformed and damaged by a strong push, and the engagement and holding are not performed at both the first and second positions. In manufacturing, it is possible to easily manufacture and assemble the push-type switch without the need for highly accurate adjustment work.

[Advantage of Invention] As described in detail above, in the push-type switch of the present invention, the movable body has the tubular shape even when the operation element is pushed too hard to hold the engagement at the first position. It is securely engaged and held in the second position in the case. The manufacturing and assembling can be easily performed without a complicated adjusting and assembling process, and the stable and highly accurate switch operation can be performed.

At least one of the protrusions The surface of the path facing the first concave portion is inclined more gently than the right angle with respect to the sliding surface, and at the first and second pushing positions, the contact portion has the first and second contact portions, respectively. Located in the second recess, and in the vicinity of the first recess of the first path,
A stopper is provided in the cylindrical case to prevent the hook spring from being displaced more than a predetermined amount in the perpendicular direction when the contact portion is separated from the sliding surface by a predetermined distance due to the contact portion riding on the protrusion. When the vicinity of the bent portion of the hook spring is in contact with the stopper and the contact portion is separated from the sliding surface by a predetermined distance, when the push-in is further performed, the contact portion comes close to the end of the second path. The push-type switch characterized in that the mounting position of the stopper is selected so as to be positioned.
