DETAILED DESCRIPTION OF THE INVENTION This invention relates to a console box door latching device suitable for use in a console box for an automobile.

Conventionally, in the console box door latching device shown in FIGS. 10 to 13, the door installed at the rotating end 20 (see FIG. 13) of the console box door 2 due to poor installation accuracy of the hinge H, etc. Even if the claw portion 41 of the door striker 3 and the claw hooking hole 5 provided in the console box body 1 are relatively shifted laterally, the claw portion 41 of the door striker 3 may be In order to securely engage the hook in the hook latching hole 5, the opening width of the hook latching hole 5 is made larger than the width of the hook 41, so that there is a sufficient width to allow for the lateral deviation. Dimensions need to be set.

However, when each width dimension is set in anticipation of lateral deviation between the claw portion 41 and the claw hooking hole 5,
A gap in the width direction between the claw portion 41 and the claw hooking portion 5
As C' (shown in FIG. 12) increases, the gap C' becomes a play in the console box door when the console box door 2 is closed.

Therefore, although the configuration is designed to absorb the lateral displacement between the claw portion 41 and the claw hooking hole 5, backlash occurs in the console box door 2, and as a result, the position of the console box door 2 changes. It is not possible to prevent misalignment, and this also results in deterioration in the construction quality and appearance of the console box door 2.

Therefore, in order to reduce the backlash of the console box door 2 due to the gap C' and prevent positional shift, it is possible to take measures such as increasing the rigidity of the hinge H, product accuracy, and installation accuracy. However, it is disadvantageous in terms of cost and weight.

In addition, in the case of the conventional door latch devices shown in FIGS. 10 to 13, the latch portion formed by the latch between the claw portion 41 and the claw latch hole 5 is able to handle the load in the opening/closing direction of the console box door 2. , other loads, and external forces, etc., so the reliability and durability of the hooking portion are reduced.

10 to 13, reference numeral B indicates a bracket for attaching the door striker 3 to the console box door 2, reference numeral 4 indicates a block on which the claw portion 41 is formed, and reference numeral 42 indicates the block 4. 12 shows a control tongue extending from the top of the figure.

Therefore, the purpose of this invention is to prevent rattling and displacement of the console box door without increasing cost, weight, etc., and without impairing the reliability and durability of the locking device.

In order to achieve this purpose, this invention has a console box door 2 attached to the console box body 1 by a hinge H,
The door striker 3, which is rotatably attached to the door rotation end 20 by a shaft S, consists of a block 4 forming a pawl portion 41, and an operating tongue piece 42 that branches off from this block 4 and extends. In this console box door latching device, the claw portion 41 of the door striker 3 is latched to the claw latching hole 5 provided in the console box body 1 facing the door striker 3 with a spring bias. A striker gripping part 6 is formed in the vicinity of the claw hooking hole 5 of the console box body 1 to abut against and sandwich the block 4 of the door striker 3, and this striker gripping part 6 and the door striker 3 At least one of the abutting portions 60, 40 with the block 4 is formed with an inclined surface against which at least the other (60, 40) is abutted and guided, and the abutting portion 60 of the striker gripping portion 6 and the door striker The abutting portion 40 of the block 4 of No. 3 forms an abutting portion that abuts in a locked state.

According to the console box door latching device according to this invention, the slope formed on at least one of the abutting portion 40 of the block 4 of the door striker 3 and the abutting portion 60 of the striker gripping portion 6 allows the locking device to lock at least the other (4).
0, 60) are brought into contact and guided, the abutting portion 40 of the block 4 of the door striker 3 is sandwiched between the abutting portion 60 of the striker gripping portion 6, and the claw portion 41 and the claw hooking portion 5 are In the locked state, the block 4 of the door striker 3 and the abutting portions 40, 60 of the striker gripping portion 6 abut each other through their slopes and abutting portions, so that the abutting portions 40, 6
Since the gap C between 0 (between the slope and the abutment part) is set to zero or minimized, the following effects (a) to (c) are achieved.

(b) It is possible to prevent the console box door from rattling when it is closed and from shifting its position due to this, and to improve the quality of its installation and its appearance.

(b) All loads and external forces in directions other than the opening/closing direction of the console box door are caused by the pinching caused by the abutment of each abutting part other than the latch part, and by the contact between the slope of the abutting part and the abutting part. Therefore, the latching portion only needs to receive the load in the opening/closing direction, and the reliability and durability of the latching device including this latching portion can be improved.

(c) With (a) and (b) above, it is possible to reduce the input load other than the load for pivoting that is applied to the hinge part, and there is no need to increase the rigidity and accuracy of this hinge. It is possible to reduce the weight and cost of the hinge.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The drawings from FIG. 1 to FIG. 5 show a first embodiment of this invention, and as can be seen from FIG. 1, a console box door 2 is attached to a console box body 1 by a hinge H. The rotating end 2 of this console box door 2
0, door striker 3 via bracket B.
is rotatably mounted on a shaft S.

As can be seen from FIG. 3, the door striker 3 consists of a block 4 forming a claw portion 41 and an operating tongue 42 branching off from the block 4 and extending therefrom.

Further, as can be seen from FIGS. 2a and 2b, the console box main body 1 is provided with a hooking hole 5 opposite to the claw portion 41 of the door striker 3.

The claw portion 41 of the door striker 3 is spring-biased and engaged with the claw hooking hole 5 of the console box body 1, thereby holding the console box door 2 in a closed state and closing the console box door. The opening operation No. 2 is performed by releasing the engagement between the claw portion 41 and the claw hooking portion 5 by releasing the engagement of the operation tongue 42 of the door striker 3. .

As shown in FIGS. 1 to 5, the console box door latching device is constructed in this manner, and as shown in FIGS. Along the vicinity of both edges in the width direction of the locking hole 5, striker gripping portions 6 are formed that abut against both sides in the width direction of the block 4 of the door striker 3 and sandwich both sides of the block 4 in the width direction. do.

Specifically, it abuts and abuts against the abutting portions 40, which are vertical wall surfaces on both sides of the block 4 of the door striker 3 in the width direction, and pinches these abutting portions 40 from both sides in the width direction. A striker gripping part 6 having abutting parts 60 formed at intervals in the width direction is formed along the vicinity of both widthwise edges of the hooking hole 5 provided in the console box body 1.

Further, as can be seen from FIGS. 2a, 2b, and 4, the door striker 3 block 4
The abutting portions 40 on both sides in the width direction are guided into contact with each other to form slopes for sliding down.

In this embodiment, a rounded curved changing surface 7 is formed at the upper corner of the slope, and the abutting portions 60 formed on both sides of the striker gripping portion 6 in the width direction are arranged upwardly. It is formed in a shape that smoothly expands towards the target.

Further, in order to close the console box door 2, when the claw portion 41 and the claw-shaped hole 5 are engaged, the slope of the abutting portion 60 of the striker gripping portion 6 and the block of the door striker 3 are connected. A contact portion is formed with which the abutment portion 40 of No. 4 comes into contact.

That is, in this embodiment, in the locked state, the abutment part 40 of the block 4 of the door striker 3, which faces the slope formed on the vertical wall surface of the abutment part 60 of the striker gripping part 6, comes into contact with the slope. , an abutting portion is formed in which the gap C between the abutting portions 40 and 60 is zero or minimal.

Due to such abutting, the gap C between these slopes and the abutting portion naturally becomes zero or extremely small.

On the other hand, the drawings from FIG. 6 to FIG. 8 show a second embodiment of this invention, and the difference from the first embodiment is that the forming parts of the slope and the contact part are reversed. Specifically, as can be seen from FIGS. 6 and 7, the abutting portion 6 of the striker gripping portion 6
Block 4 of door striker 3 abutting against 0
A slope is formed on the abutment portion 40 of the striker gripping portion 6, and the abutment portion 60 of the striker gripping portion 6 faces the slope,
A contact portion is formed that contacts the slope in the latched state.

In this second embodiment as well, a curved curved surface 7' is formed at the upper corner of the slope formed on the abutting portion 40 of the block 4 of the door striker 3.

The drawing in FIG. 9 shows a third embodiment of this invention, and this third embodiment is a combination of the configurations of the first and second embodiments described above. The abutting portion 40 of the block 4 of the door striker 3 and the abutting portion 60 of the striker gripping portion 6 are both formed with sloped surfaces, and the abutting portions of the two sloped surfaces in the locked state are respectively It becomes the contact part.

Moreover, the abutting portion 60 of the striker gripping portion 6
The slope formed on the door striker 3 has a rounded curved surface 7 at its upper corner, and the slope formed at the abutting portion 40 of the block 4 of the door striker 3 has a rounded curved surface 7 at its lower corner. , 7' are formed.

In this way, by the slope formed on at least one of the abutment part 40 of the block 4 of the door striker 3 and the abutment part 60 of the striker grip part 6,
While at least the other side (40, 60) abuts and is guided in abutment, the abutting part 40 of the block 4 of the door striker 3 is sandwiched between the abutting part 60 of the striker grip part 6, and the claw part 41 and the claw are hooked. In the locked state with the door striker 3, the abutting parts 40, 60 of the block 4 of the door striker 3 and the striker gripping part 6, respectively.
However, by making contact between the slope and the abutting part, the gap C between each of the abutting parts 40 and 60 (between the slope and the abutting part) can be made zero or minimized. can.

In other words, even if there is a lateral shift between each member, such as when the block 4 of the door striker 3 is laterally shifted relative to the console box body 1, the abutting portion of the block 4 40 and the abutting portion 60 of the striker gripping portion 6 abut against each other, and the abutting portion 40 of this block 4 is sandwiched between the abutting portion 60 of the striker gripping portion 6, so that this block 4 Parts 40 and 60
The claw portion 41 and the claw hooking portion 5 are moved to the normal hooking position as shown in FIGS. It can be hung as.

Therefore, in this locked state, the gap C between the abutting parts 40 and 60, that is, between the slope and the abutting part, can be made zero or extremely small, and this gap C
It is possible to eliminate or minimize the backlash due to

Furthermore, even if the width dimensions of the claw portion 41 and the claw hooking portion 5 are set in consideration of lateral slippage due to poor product accuracy and installation precision of each of the above-mentioned members, etc., in the hooked state, as described above, The gap C can be made zero or extremely small, and the backlash caused by this gap C can also be eliminated or made very small.

Here, if the angle α of the slope formed at the abutment part 60 of the striker grip part 6 shown in FIG. If this is done, the force that moves the door striker 3 upward will increase, which will have a negative effect on the engagement relationship between the claw portion 41 of the door striker 3 and the claw hooking hole 5 provided in the console box body 1. .

Therefore, in order to set the slope angle α to a certain degree small and increase the positional deviation accuracy tolerance D,
At the upper corners of the slope, curved curved surfaces 7, 7' are formed.

In addition, the hook portion formed by the claw portion 42 and the hook hook portion 5 has a hooking effect when the console box door 2 is closed.
Since the console box door 2 only functions to release the latch when opened, and only receives the load in the opening/closing direction of the console box door 2, all loads other than the load in the opening/closing direction and other external forces are applied to the block 4.
and the abutment portion 60 of the striker gripping portion 6 and the striker gripping portion 6
The abutting portion 40 of the block 4 by the abutting portion 60 of
It can be received at these parts due to the pinching of the surface and the contact between the slope and the contact part.

Further, with such a configuration, the hinge H only needs to receive a pivoting load for rotating the console box door 2, and the load applied to the hinge H can be reduced, so that the gap C can be reduced.
Coupled with this, there is no need to take measures such as increasing the rigidity of the hinge H, product accuracy, and installation accuracy.

Since this invention is constructed and operates as described above, it is possible to achieve the above-mentioned effects of this invention.
