DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a drawer such as a small container, an ashtray and a cup holder provided on an instrument panel of an automobile.

[0002]

2. Description of the Related Art In recent years, as shown in Japanese Utility Model Publication No. 4-48987, the housing is inclined and fixed to the instrument panel side so as to rise forward as shown in Japanese Utility Model Publication No. 4-48987. If you pull out the case that can be moved forward and backward diagonally upward,
In the moving process, a case has been proposed in which the case is gradually turned downward, and finally, the case can be pulled out in a horizontal state.

Although not specifically shown, the drawer is mainly composed of a housing, a case and a slider, and the housing is formed in a box shape by combining an independent upper wall, a bottom wall and left and right side walls. The guide groove and the guide groove for inserting a pin, which will be described later, and a V-shaped groove for guiding the Soloban ball-shaped roller are provided on the inner surfaces of the left and right side walls of the body. The entire length between the front and rear ends is formed in a straight line parallel to the bottom wall of the housing, and the guide groove is formed in a straight line parallel to the bottom wall from the rear end to the middle toward the front end, and extends from the middle to the front end. It is formed so as to be in a state of rising and inclining.

[0004] In the case, a pair of extension arms are extended to the rear end side, and the base of each extension arm and the slider are rotatable by a first pin whose tip projects outward. At the same time, a second pin is provided at the rear end of each extension arm, the tip of which protrudes outward and outward. The entire slider is formed in a rectangular shape and attached to the case in the opening direction. A V-shaped constant-pressure spring, a rotary damper that meshes with a rack provided on the bottom wall side of the housing, a lock piece that engages and disengages with a raised latch provided on a rising portion of the bottom wall of the housing, The configuration is such that a Soloban ball-shaped roller or the like that slides in the groove is additionally provided.

Therefore, in actual use, when the housing is inclined and fixed to the instrument panel side so as to rise forward, and the slider and the case are pushed into the housing together, the lock piece on the slider side is raised. Engaging the latch locks the case in the closed position within the housing against the spring pressure of the constant pressure spring. Further, when the case is slightly pushed into the housing in such a state, the engagement of the lock piece with the raised latch is released, so that the case moves forward in the opening direction with the spring pressure of the constant pressure spring together with the slider. In this movement process, the first pin moves straight in the guide groove provided on both side walls of the housing, while the second pin moves in the guide groove. Move straight up to the middle, then
Since the case enters the upwardly inclined portion of the guide groove, the case is gradually rotated downward with the first pin as a fulcrum, and eventually the case is pulled out in a horizontal state.

[0006]

Therefore, in the conventional drawer, even if the housing is fixed to the instrument panel in a state of being inclined, the case is kept horizontal when the case is opened. Since it can be pulled out, there is an advantage that it is possible to eliminate the worry that the stored items are biased in one direction in the case and to provide convenience in use, but on the other hand, for this purpose, other than the housing and the case normally used In addition, it is necessary to separately attach a slider such as a constant-pressure spring and a damper to move forward and backward together with the case.In addition, the housing must be formed of independent upper and lower walls and left and right side walls. However, the number of parts increases, and the apparatus itself tends to be complicated and large, and the cost is high.

In addition, under the conventional drawing device, the angle of the case with respect to the housing is determined in advance by the upwardly inclined portion of the guide groove provided on the inner surface of the side wall of the housing. If it is necessary to change the drawer angle of the case according to the situation, etc., it is practically impossible to use the drawer of the same standard in addition to its structure.
It was absolutely impossible to use it for a normal horizontal draw-out type device. For this reason, in the past, a dedicated drawer had to be prepared individually for each vehicle type in which the case withdrawal angle was different, so there was a major problem that lacked economy and rationality. is there.

[0008]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional drawer, and has a housing having an opening and a movable arrangement within the housing. The case is provided, a linear guide portion is provided on the inner surface of both side walls of the housing, a shaft supported by the linear guide portion is attached to the rear end side of the case, and the lower portion on both sides of the case A guide member having a sliding contact surface that determines the pull-out angle of the case is replaceably mounted, and the sliding contact surface of each guide member is slid on a guide surface provided on the opening side of the housing. did.

[0009]

Therefore, in the drawer of the present invention, when the case is pulled out from the housing, the shaft moves on the guide portion and the sliding contact surface of the guide member slides on the guide surface on the housing side. Since the case moves, the case can be pulled out to a state having a predetermined angle with respect to the housing according to the angle given to the sliding contact surface. Further, in the drawer of the present invention, since the guide member for determining the drawer angle of the case is configured to be exchangeably mounted on the case side, only the guide member is appropriately replaced, and thereafter, all Under the same standard, the case can be pulled out of the housing at a predetermined angle.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an embodiment which illustrates the present invention.
As shown in FIG. 1, it is assumed that the housing 1 includes a housing 1 that is fixed to the instrument panel side so as to be inclined upward and forward, and a case 21 that is disposed in the housing 1 so as to be able to move forward and backward. However, the feature is that the following configuration is adopted.

First, the housing 1 is integrally formed of a synthetic resin into a box-shaped body having an opening on the front side, and as shown in FIG.
a pair of racks 2 that are engaged with each other,
a linear guide rail 3 serving as a guide portion on the inner surface opposite to b
Are provided in parallel with the bottom wall portion 1c, and two mounting windows 4a and 4b for opening the following stopper members 7 to be adjustable in angle are provided near the opening portions of the both side wall portions 1b. Arc-shaped receiving teeth 5 near windows 4a and 4b
Are integrally provided, and the raised latch 6 is provided on the rear wall 1d side.
Is provided. Note that one of the two mounting windows 4a and 4b has a narrow groove-shaped semicircle, and the other 4b has a thick groove-shaped quarter circle.

The stopper member 7 is formed of a synthetic resin in the same form symmetrical to the left and right, and has a fixed claw 8a and a guide receiving piece 9 which are engaged in the one mounting window 4a on each side surface.
And a fixing claw 8b to be engaged in the other mounting window 4b is formed individually, and a triangular projection 2 described later is formed at a substantially central portion.
6 is provided with a protruding locking groove 10 of a similar shape, and
Positioning teeth 11 engaging with the receiving teeth 5 at the lower end side
Is formed. Accordingly, the pair of left and right stopper members 7 is attached to the mounting window 4 a of the guide receiving piece 9.
The positioning teeth 11 are engaged with the receiving teeth 5 of the housing 1 at a predetermined position while rotating in a predetermined direction by obtaining a guiding action in the inside, and the fixing claws 8a and 8b are attached to the corresponding mounting positions. If the locking grooves 10 are locked to the holes of the windows 4a and 4b, the locking grooves 10 protrude from the mounting window 4b into the housing 1 at an arbitrary angle.

The case 21 is also integrally formed of synthetic resin, and as shown in FIG. 3, a pair of bearing portions 22 are formed on the rear end side, and a pair of bearing portions 22 are formed on each of the bearing portions 22. The rotatable shaft 23 integrally having the gear 23a is rotatably mounted, and in particular, the rear lower surface is inclined at a desired angle, and a guide member 31 to be described later is exchangeably mounted on a lower portion on both sides including the inclined area. A step portion 24 and a plurality of locking portions 25 are formed, and a triangular projection 26 for locking in the locking recessed groove portion 10 is integrally provided on the rear end side of both side portions. A lock piece 27 that engages and disengages with the raised latch 6 is provided. In the figure, 2
Reference numeral 8 denotes a torsion coil spring which is mounted on the rotating shaft 23 and constantly urges the case 21 in the opening direction. The torsion coil spring 28 has one end fixed to the rotating shaft 23 and the other end. The case 21 is locked to the locking portion 29 provided on the rear end side of the case 21 so that the case 21
And a rotary damper 30 for applying a braking force to the movement of the case 21 in the opening direction by elastically pressing against the guide surface 12 provided near the opening. The rotary damper 30 is fixed to the side of the case 21 in a state of engaging with one of the gears 23a.

The guide member 31 is also formed of a synthetic resin in the same form symmetrical to the left and right, and forms a sliding contact surface 32 provided with a desired inclination angle for determining a pull-out angle of the case 21 at a lower end edge thereof. And the case 2
A plurality of locking claws 33 that lock to each of the locking portions 25 are formed. Therefore, the pair of left and right guide members 31 is connected to the concave step portion 2 of the case 21 through the locking claw 33.
4 and the case 21 is pulled out of the housing 1, the sliding surface 32 of each guide member 31 slides on the guide surface 12 near the opening of the housing 1, and the sliding surface 3
Since the pull-out angle of the case 21 is determined according to the tilt angle of 2, the slide angle of the sliding surface 32 is different from that of the guide member 31 only by separately preparing the pull-out angle of the same case 21. It can be changed freely.

Therefore, when assembling the case 21 to the housing 1, first, the rotating shaft 23 is attached to the bearing portion 22 of the case 21, and
4 and the pair of left and right guide members 31 are attached to the concave step portions 24 formed at the lower portions on both sides of the case 21 and the case 21 is pushed into the housing 1. -As shown in Fig. 5, the rotating shaft 2
3 are movably supported on the linear guide rail 3, and thereafter, both sides of the housing 1 are formed under an angle corresponding to the inclination angle of the sliding contact surface 32 of the guide member 31. A pair of left and right stopper members 7 may be attached to the wall 1b, and the housing 1 may be fixed to an instrument panel (not shown) so as to be raised forward.

When the case 21 is pushed into the housing 1 during actual use, the rotating shaft 23 is driven by its own gear 23a in conjunction with the pushing of the case 21.
Is rotationally moved in the same direction on the guide rail 3 while engaging the corresponding rack 2 against the spring pressure of the torsion coil spring 28, and finally the lock piece 27
4 or 6, the case 21 is securely locked at the closed position in the housing 1 against the urging spring pressure of the torsion coil spring 28. As shown in FIG. In this state, the front end side of the sliding contact surface 32 of each guide member 31 is in contact with the guide surface 12, but the other sliding contact surfaces 32 are not in contact with the housing 1 at all.

Then, when the case 21 is slightly pushed into the housing 1 in the closed lock state, the lock pieces 2
7 is disengaged from the latch 6, so that the case 21 advances in the opening direction by the spring pressure of the torsion coil spring 28. In this movement process, as shown in FIG. At the same time, the rotating shaft 23 moves in the same direction on the guide rail 3 while rotating, and at the same time, the action of the spring pressure of the torsion coil spring 28 and the weight of the case 21 itself causes each guide to rotate. Member 31
As a result, the sliding contact surface 32 is surely slid on the guide surface 12 along the angle of inclination, whereby the case 21 moves forward while rotating gradually downward with the rotating shaft 23 as a fulcrum. Finally, as shown in FIG.
The case 21 is moved from the opening of the housing 1 to the sliding contact surface 32.
In the horizontal state at an angle determined by

This case 21 is, as shown in FIG.
When the projection 26 provided on its own side is locked in the locking groove 10 of the stopper member 7, its forward movement is regulated. In such regulation, as described above. Since the mounting angle of the stopper member 7 in accordance with the pull-out angle of the case 21 has already been determined by the engagement of the positioning tooth portion 11 with the receiving tooth portion 5, the projection 26 is automatically guided into the locking concave groove portion 10. In addition to this, it is possible to effectively prevent the case 21 in the open state from rattling in the vertical and horizontal directions. That is, under the present embodiment, the pull-out angle of the case 21 is determined solely by the inclination angle given to the sliding contact surface 32 of the guide member 31, so that the same angle as the determined angle is used. By simply attaching the stopper member 7 to the housing 1 side, the projection 26 interlocking with the case 21 can be smoothly guided into the locking concave groove portion 10 to ensure the full open state of the case 21. In this case, after setting the rotation center of the stopper member 7 to be concentric with the rotation center of the rotating shaft 23 when fully opened, a numerical value indicating the mounting angle of the stopper member 7 is displayed in advance on the receiving gear 5 side. By doing so, the operation of attaching the stopper member 7 at a predetermined angle can be performed very accurately and easily.

Therefore, in this embodiment, even if the housing 1 and the case 21 are of the same standard, the guide members 31 attached to the lower portions on both sides of the case 21 are appropriately replaced, and By simply attaching the stopper member 7 to the housing 1 in accordance with the inclination angle of the sliding contact surface 32 of the housing 31, it is possible to freely change the withdrawal angle of the case 21 with respect to the housing 1; By individually providing the guide members 31 having different angles, any drawer device can be used as long as the drawer device is configured to incline and fix the housing 1 in a front-up state.

Further, if this is further developed, as shown in FIG. 10, if the inclination angle of the sliding contact surface 32 of the guide member 31 is set to zero, that is, the horizontal level, it is illustrated under the same standard. As described above, since it can sufficiently be used also as a normal horizontal drawer-type drawer, its use range becomes very large. Also, in this case, as shown in FIG. 11, the projection 26 of the case 21 which advances in the horizontal state is smoothly guided into the locking groove 10 again.
It goes without saying that the occlusal position of the positioning tooth portion 11 with respect to the receiving tooth portion 5 is changed and the pair of left and right stopper members 7 are attached to the housing 1 side. In the above-described embodiment, the so-called push-open type drawer is intended, but the present invention is not limited to this, and it goes without saying that the present invention can be applied to a manual type drawer. Further, the drawer itself is not limited to the illustrated accessory case.

[0021]

As described above, according to the present invention, by adopting the above configuration, the guide member having the sliding contact surface for determining the pull-out angle of the case is simply replaced as appropriate, and thereafter, all of the other components are made under the same standard. Since the case can be pulled out from the housing at a predetermined angle, an extremely economical and rational drawing device can be provided for the first time while greatly simplifying the structure itself. In addition, the case can be pulled out of the housing at a predetermined angle without using a conventional slider, and the housing can be formed as an integral structure without using a conventional divided structure, so that the number of parts can be reduced. The simplification of the assembly work can also be greatly expected.
