Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slide body device of a type that is automatically pushed out by a predetermined actuator, and particularly relates to a slide body device that is automatically protruded by a predetermined actuator, and particularly relates to a slide body device that is automatically protruded by a predetermined actuator. It concerns structural improvements.

As an example of the automatic ejecting sliding body device as described above,
There is an ashtray device for vehicles. Such an automatic ejecting type ashtray device is configured such that both sides of the ashtray case are held by guide rails provided on a retainer at a predetermined position Y1 and are guided in the loading/unloading direction, and a predetermined actuator, For example, the ashtray case is always urged in the direction of protruding from the retainer by a spiral spring or the like that urges in one rotation direction a pinion that engages with a rack fixed to the ashtray case. When the ashtray case is in the closed position stored in the retainer, it is held in that position by the locking action of the locking mechanism, but when the ashtray case is pushed in slightly, the lock is released and the ashtray case is opened. According to the urging force of the above-mentioned actuator, it is usually configured to be automatically pushed out via a damper for deceleration, and the guide rail and ashtray case of such a retainer are often made of resin. .

By the way, in such an automatic ejecting type ashtray device, unlike a manual pull-out type ashtray device, a plate spring or the like is inserted between the guide rail of the retainer and the sliding portion of both sides of the ashtray case to remove looseness. It is not desirable to do so. This is because if you do this, the sliding resistance of the ashtray case will increase and the ashtray case will not be able to be pushed out smoothly even by the biasing force of the actuator. This is because if it is applied to the actuator, a large force will be required to push it into the storage position, resulting in a poor operational feeling.

Dish n point Therefore, conventionally, in order to keep the sliding resistance of the ashtray case to a small level, the both sides of the ashtray case are guided in the loading/unloading direction by the guide rails of the retainer without using the above-mentioned leaf springs. However, with this, the ashtray case tends to rattle. For example, when the ashtray case is extended to the open position, there is a problem in that the ashtray case rattles due to vibrations of the vehicle or the like.

This is a problem that occurs not only in ashtray devices for vehicles but also in automatic ejecting type slide body devices in general.

The present invention of Ruta Uran was made to solve such problems, and as mentioned above, both sides of the slide body are guided in the direction of insertion and removal by the guide rails of the retainer, and , a slide body device of a type that is automatically ejected according to the biasing force of a predetermined actuator, and at least both sides of the slide body and the guide rail are made of resin; One side is provided with a guide groove, and the other side is provided with a guide portion that is slidably engaged in the guide groove, and either one of the guide groove and the guide portion is provided with at least one engagement protrusion. and at least one elastic claw part that is elastically deformed by engaging with the engagement protrusion is integrally provided on the other of them, so that the engagement protrusion and the elastic claw part are engaged with each other. When it is pressed, the pressing force caused by the elastic deformation of the elastic claw part,
This is characterized in that the side portion of the slide body is pressed against the guide rail of the retainer.

In other words, the above-mentioned elastic claw does not apply a pressing force all the time, but applies a pushing force only after it engages with the retaining protrusion. Before the mating convex portion is engaged, the side portion of the slide body can freely slide on the guide rail of the retainer. and,
It is preferable that the engagement timing between the engagement convex portion and the elastic claw portion coincides with the timing when the slide body is ejected to the ejection limit. Based on the elastic deformation of the slide body, the side portion of the slide body is pressed against the guide rail of the retainer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, in order to clarify the present invention more specifically, an embodiment in which the present invention is applied to an ashtray device for a vehicle will be described in detail based on the drawings.

FIG. 1 shows an exploded perspective view of such an automatically ejecting vehicle ashtray device disassembled into individual parts. This ashtray device includes an ashtray case 2 for storing cigarette butts, and a retainer 4 that holds both sides of the ashtray case 2. The ashtray case 2 is fixed to an instrument panel, etc., and serves to guide the ashtray case 2 in the loading/unloading direction.

The ashtray case 2 is made of fire-resistant resin,
Guide protrusions 6 that function as guide portions are formed in the upper portions of both sides of the ashtray case 2 and parallel to each other along the direction in which the ashtray case 2 is taken in and taken out, and have a cross section that projects laterally. Further, a fire protection protector 8 is rotatably provided via a shaft 10 so as to cover the opening of the ashtray case 2.
Moreover, it is urged upward by a spring 12. Furthermore, a rack 14 extending in the loading/unloading direction is fixed to the bottom outer surface of the ashtray case 2, and a locking pin 16 is provided to protrude downward. A lock release lever 20 having a protrusion 18 is rotatably attached to the inside of the handle of the ashtray case 2.

On the other hand, the retainer 4 is made of sheet metal, and a pair of resin guide rails 22 are provided in parallel to each other on the inner surfaces of opposite sides of the retainer 4, and mounting protrusions formed on the back surfaces of each retainer 4 are provided. 24 are fixed to both sides of the retainer 4 by being fitted into the holes 26 in a manner that prevents the retainer from being removed. Guide grooves 28 each having a rectangular groove cross section are formed on the mutually opposing inner surfaces of the guide rails 22 so as to face each other along the longitudinal direction. The guide protrusions 6 on both sides are slidably engaged and guided in the insertion/extraction direction.

A lighting case 34 is attached to a window 30 formed in the upper part of the retainer 4 via a filter 32, and a protector guide 36 for guiding the protector 8 is fixed to the inner surface of the upper part. This protector guide 3
6 has a stopper portion 38 which also plays the role of defining the limit of protrusion of the ashtray case 2 from the retainer 4 by abutting the protrusion 40 formed on the protector 8.

A bracket 42 is fixed to the lower part of the retainer 4 so as to straddle both sides of the retainer 4 (this can also be seen as a part of the retainer 4). As described in the specification of No. 58-88262, a pinion 44 meshing with the rack 14 of the ashtray case 2 is rotatably supported via the case 46 and is rotated in one direction by a precompressed spiral spring 48. The spiral spring 48 is energized and the ashtray case 2
It functions as an actuator that biases the retainer 4 toward the seat without protruding from the retainer 4.

Further, on the lower surface of the bracket 42, an elastic cam piece 50 is provided.
The ashtray case 2 is rotatably mounted in a state where it is always biased in the A direction by a spring 52, and when the ashtray case 2 is pushed into the retainer 4, the ashtray case is inserted into the recess 54 of the cam groove of the elastic cam piece 50. By locking the second locking pin 16, the ashtray case 2 is held in the pushed-in storage position. However, if the ashtray case 2 is pushed in slightly in this state, the locking pin 16 moves within the cam groove as shown in FIG. 2, causing the elastic cam piece 50 to elastically deform downward and detach. As a result, the locking is released and the ashtray case 2 is allowed to protrude, and these elastic cam pieces 50, locking pins 16, etc. constitute a locking mechanism.

In the unlocked state, the ashtray case 2 is automatically pushed out based on the engagement between the pinion 44 and the rack 14 according to the biasing force of the spiral spring 48, but the pinion 44 is 56, and the rotation of this gear 58 is suppressed by the viscous resistance of the fluid, so that an appropriate ejection speed is given to the ashtray case 2.

In addition, if the ashtray case 2 becomes clogged with cigarette butts, etc., the ashtray case 2
If it is not possible to push the lock slightly from the storage position, rotate the lock release lever 2o and release the protrusion 1 of the lock release lever 2o.
By pushing down the elastic cam piece 50 at 8, the locking of the locking pin 16 can be released.

Each guide protrusion 6 formed on both sides of the ashtray case 2 is
The retainer 4 is fitted into the guide groove 28 of each guide rail 22, but in this state, the lower surface of the guide protrusion 6 is brought into sliding contact with the lower surface of the guide groove 28, while the guide protrusion 6
A certain gap is created between the upper surface and the upper surface of the guide groove 28. Each upper side of the guide protrusion 6 is provided with a height such that the two engaging protrusions 60 and 62 protrude upward, and a slight clearance is created between the upper side of the guide groove 28 and the upper side of the guide groove 28. They are provided in each. Each of these engagement protrusions 60 and 62 occupies a position corresponding to each other in the width direction of the ashtray case 2, but the engagement protrusion 60 is located at the end (rear end) of the ashtray case 2 in the pushing direction. The engaging convex portion 62 is
It is formed at a position spaced a predetermined distance from the engagement convex portion 60 in the direction in which the ashtray case 2 protrudes.

On the other hand, two elastic claws 64 and 66 are provided on the upper surface of the guide groove 28 of each guide rail 22, respectively. These elastic claws 64 and 66 are both formed of resin integral with the guide rail 22 by making a slit 68 in the resin guide rail 22 along its contour, and are formed of a resin integral with the guide rail 22 in the groove width direction of the guide groove 28. (
In this example, elastic deformation in the vertical direction is possible.
When forming the guide rail 22, these elastic claws 64.6
6 can be molded at the same time. In addition, each elastic claw portion 6
The free ends of the guide protrusions 4 and 66 are formed in a shape that protrudes toward the upper side of the guide protrusion 6.
A slight clearance is created between the top surface and the top surface. Each of the elastic claws 66 is located at the front end of the guide rail 22 in the longitudinal direction, that is, at the end of the ashtray case 2 on the protruding side.
It is formed at a position separated from the elastic claw portion 66 in the pushing direction of the ashtray case 2 by a distance equal to the distance between the engaging convex portions 60 and 62 of the guide protrusion 6.

Moreover, as is clear from FIG. 3(a), when the ashtray case 2 is in the storage position pushed into the retainer 4, the engaging protrusions 60 and 62 and the elastic claws 64 and 6
6, and the respective distances l between the elastic claw portion 66 and the engagement protrusion 62 and between the elastic claw portion 64 and the engagement protrusion 60 are all equal, and as shown in FIG. 3(b) It is determined to be equal to the protrusion stroke (ρ) of the ashtray case 2 shown in .

Therefore, the elastic claw portion 66 and the engagement protrusion 62 and the elastic claw portion 64 and the engagement protrusion 60 are engaged with each other when the ashtray case 2 is protruded to its maximum limit. As is clear from FIG. 4, corresponding inclined surfaces 70 and 72 are formed in the portions of the engaging convex portion 62 and the elastic claw portion 66 that are engaged with each other, and these inclined surfaces 70 and 72 are The wedge effect functions to elastically deform the elastic claw portion 6G upward as the ashtray case 2 protrudes. Note that both the elastic claw portion 64 and the engaging convex portion 60 have inclined surfaces 70. which correspond to each other.
72 is similarly formed.

In the automatic ejecting ashtray device configured as described above, as shown in FIG. When pushed in, the locking by the elastic cam piece 50 is released, and the ashtray case 2 is moved to the third position based on the engagement between the rack 14 and the pinion 44 and the urging force of the spiral spring 48.
As shown in Figure (b), it is automatically ejected to the open position (extended position). Therefore, until the ashtray case 2 is pushed out from the closed position to the open position, the elastic claws 64 and 66 are not connected to the engagement protrusion except when the engagement protrusion 62 passes through the elastic claw 64. 60 and 62 are not elastically deformed, and the lower surface of the guide protrusion 6 only comes into sliding contact with the lower surface of the guide groove 28.
The sliding resistance between them is suppressed to a low level, so that even if the elastic force of the spiral spring 48 is not so strong, the ashtray case 2 can be pushed out easily and smoothly.

As shown in FIG. 3(b), just before the ashtray case 2 is ejected to the ejection limit, the retaining convex portion 62 is attached to the elastic claw portion 66, and the retaining convex portion 62 is attached to the elastic claw portion 64. The engaging protrusions 6o are engaged with each other, and in the initial stage of this engagement, as shown in FIG. are not in contact yet,
A gap δ is maintained between them. From this state,
In the process of the ashtray case 2 being pushed out a further short distance,
That is, in the process until the gap δ disappears and the protrusion 40 comes into contact with the stopper portion 38 as shown in FIG. From the state where the inclined surfaces 70 and 72 are in contact with each other, the elastic claw portion 66 is elastically deformed in the direction of being pushed upward based on the wedge action of the inclined surfaces 70 and 72, as shown in FIG. As a result, the lower surfaces of the six guide protrusions are pressed against the lower surfaces of the guide grooves 28 by the pressing force (original return force) of the elastic claws 66. Further, the other elastic claw portion 64 is similarly elastically deformed by engagement with the engagement convex portion 60, and exerts a pressing action.

As a result, the guide protrusions 6 on both sides of the ashtray case 2 are pressed against the lower surface of the guide groove 28 of the guide rail 22 by the elastic claws 66 and 64 at two locations separated in the longitudinal direction, for a total of four locations. Therefore, when the ashtray case 2 is used for smoking in the open position, it does not wobble due to vibrations of the vehicle and is kept stable.

1. When the ashtray case 2 is pushed into the retainer 4 against the biasing force of the spiral spring 48, the elastic claws 66 and the engagement protrusions 62 engage, and the elastic claws 64 engage with the engagement protrusions. By respectively releasing the engagement with the portion 60,
The elastic claws 66 and 64 return to their original shapes, and as a result, a slight clearance is created between the upper surface of the guide protrusion 6 and the upper surface of the guide groove 28, creating a sliding resistance between them. Since the ashtray case 2 can be kept small, the ashtray case 2 can be smoothly pushed into the retainer 4. The fact that this sliding resistance is small is the same in the process of ejecting the ashtray case 2, and as mentioned above, the spring force of the spiral spring 48 as an actuator is sufficient to be relatively small. Due to the synergistic effect with the dynamic resistance, the force required to push the ashtray case 2 is small, and the operational feeling is improved.

In the embodiment described above, when the ashtray case 2 reaches its protrusion limit, the inclined surface 70 of the engagement convex portion 62 and the elastic claw portion 66 are biased by the spiral spring 48. The elastic claw portion 66 was designed to perform a pressing action when the ends of the inclined surface 72 were in partial contact with each other, but as shown in FIG. 8, the elastic claw portion 66 Their relative positions can also be determined so that the pressing action is achieved when the engagement protrusion 62 is completely mounted on the top.

The same applies to the relationship between the elastic claw portion 64 and the engagement protrusion 60.

Further, in the above embodiment, the guide groove 28 is formed in the guide rail 22, and the guide protrusions 6 are formed on both sides of the ashtray case 2, but the relationship is reversed.
It is also possible to form guide protrusions on the guide rail 22 and guide grooves on both sides of the ashtray case 2, and also to form engaging convex portions on the guide grooves and elastic claw portions on the guide protrusions. Furthermore, it is also possible to adopt embodiments in which they are combined in various ways. The retaining convex portion and the elastic claw portion are not limited to two sets on each side, but may be provided in more sets or one set each, and their relative positions are not limited to the above embodiments. It can be determined as appropriate.

Furthermore, when providing guide parts on both sides of the ashtray case,
It is not limited to the guide protrusion, but the flange-shaped upper edge of the ashtray case 2 can also function as the guide part.

It goes without saying that there are other aspects of the present invention in which various improvements and changes have been made based on the knowledge of those skilled in the art, and the scope of application is not limited to ashtray devices, for example, small items. It can be applied to various automatic ejecting type sliding body devices such as a glove box for accommodating a computer or an automatically ejecting type control operation panel, and it goes without saying that such various embodiments are included in the present invention. be.

As described in detail above, the present invention relates to a guide groove and a guide groove in order to guide the sliding body in the insertion/extraction direction while holding the slide body with a retainer in an automatically ejecting slide body device. By providing a guide portion to be engaged with each other, and providing an engaging convex portion on one of them and an elastic claw portion on the other, the guide portions are engaged with each other at a predetermined position, for example, at the protruding end position of the slide body. , at that position, a pressing force is generated based on the elastic deformation of the elastic claw part, thus preventing the slide body from wobbling at a predetermined position. This has the effect of ensuring nimble sliding of the slide body without causing any pressing action on the parts.
