DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open stopper structure for holding a one-sided lid at its open position.

[0002]

2. Description of the Related Art A so-called one-sided lid (lid), which is openably and closably connected via a hinge provided on one side, that is, on one side, is used, for example, for an armrest of a seat of a vehicle or the like.
Or, it is generally provided as a lid such as a concave portion (accessory) having an open upper surface, which is defined in on-board equipment such as a console box. In this type of lid, the substantially vertical standing position of the main body (equipment main body) such as an armrest with respect to the seating surface (the peripheral surface of the opening of the concave portion) is positioned with respect to the substantially horizontal closing position abutted on the seating surface. Since the lid is in the open position, the lid is generally configured to be able to be held in the open position by an open stopper provided on at least one of the left and right sides as viewed from the base side where the hinge is located.

[0003] As a lid opening stopper, for example,
A so-called foldable link mechanism in which two links are foldably connected is known. In this open stopper as a folding link mechanism, the lid is held at the open position by locking the two link arms substantially in a straight line, and the lid can be closed by releasing the straight state and folding. Become.

[0004]

By the way, in a known folding link mechanism forming an opening stopper, one end of each link arm is interconnected by a pivot pin, and the other end is further connected to a lid and an armrest body. Therefore, it is necessary to pivotally connect to the bracket via individual pivot pins, so that the number of parts is large, the number of working steps is increased, and the configuration is inevitably complicated.

[0005] A clearance is usually provided at the pivot point of each link arm to ensure smooth rotation. However, an increase in the number of pivot points of the link arm is apt to cause rattling of the link mechanism itself, so that it is inevitable that the stability of the lid at the time of opening is inferior.

[0006] Further, this type of folding link mechanism requires a storage space for storing the folded link arm without exposing it to the outside with the closure of the lid. It is provided on the side. However, the configuration of providing such a storage space in the lid has difficulties in terms of layout,
It is easy to increase the size of the lid.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lid opening stopper structure capable of preventing an increase in the number of parts and occurrence of rattling.

[0008]

According to the present invention, in order to attain this object, the upper surface opening of a predetermined concave portion defined in the equipment body can be freely opened and closed via a hinge arranged on one side. An opening stopper, which is capable of holding the one-sided lid connected to and supported by the main body in its open position, is formed from a stopper arm pivotally attached to the base end of the lid, and this stopper arm is provided on the opening peripheral surface of the recess. It is freely inserted into the storage recess on the equipment main body side through insertion into a corresponding insertion hole formed partially. The stopper arm has an elastic projection that can be elastically deformed in the reducing direction at an intermediate portion of the hinge side, and a detachment preventing claw that can be engaged with the back edge of the opening peripheral surface insertion hole. Each of the lids is formed so as to be able to hold the lid at the open position under the engagement of the elastic projection with the peripheral edge of the opening peripheral surface portion insertion hole.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 and 2, in the lid opening stopper structure 10 according to the present invention, the lid 12
It is formed in a so-called one-sided opening that is opened and closed by the rotation of one side (base side) 12a through the hinge 14. And
The lid 12 can be held in a closed position shown in FIG. 3 and an open position shown in FIG. 1 by a closing stopper 16 and an opening stopper 18, respectively.

As shown in FIG. 2, as this kind of lid 12, for example, a lid (lid) for a concave portion 22 which can be used as an accessory box or the like and is defined in an on-vehicle facility such as an armrest 20 can be exemplified. .

As shown in FIGS. 1 and 2, the lid 12 is formed, for example, in a substantially rectangular shape in a plane, and a hinge (hinge) 14 provided on one side thereof can open and close the upper surface opening of the concave portion 22. The armrest 20 is connected to and supported by the main body (equipment main body). The opening peripheral surface portion 22a of the concave portion 22 is usually formed flat as a seat surface on which the lid 12 is to be abutted when closed, and is placed on this seat surface, as shown in FIG. In the closed position, the lid can be held in the closed position by a closing stopper 18 provided on the opening / closing side 12b side of the lid facing the base side 12a (see FIGS. 1 and 2).

The basic configuration of the lid 12 provided on the armrest 20 is known, and the configuration itself is not the purpose of the present invention, and thus will not be described in detail here.

By the way, in this kind of lid 12,
The open position is defined as a substantially vertical standing position as shown in FIG. 1 with respect to the substantially horizontal closed position placed on the opening peripheral surface (seat surface) 22a of the concave portion. Then, for example, the lid 12 can be held at the open position by an open stopper 18 disposed on one of the left and right sides 12c with respect to the base 12a of the lid.

Here, in the present invention, the opening stopper 18 is formed by a stopper arm pivotally connected to the lid 12 at the base end 18a.

As shown in FIGS. 1 and 2, for example, a resin arm plate made of a synthetic resin material can be used as the stopper arm (open stopper) 18, and the stopper arm is pivotally supported by a bracket 26 of the lid 12. In a state where the base end 18a is pivotally supported by the pin 28, it extends outward from the insertion hole 30 of the lid so as to be swingable. As can be seen from FIGS. 1 to 3, the stopper arm 18 is inserted into the corresponding insertion hole 32 formed partially in the opening peripheral surface portion 22 a of the concave portion, and is stored on the armrest main body side. Recess
34 is freely inserted.

As shown in FIGS. 1 and 3, the insertion hole 30 of the lid and the insertion hole 32 of the peripheral surface of the concave opening can both guarantee the swing of the stopper arm 18 accompanying opening and closing of the lid 12. And the storage recess 34 is formed at least to a depth and width that allow the stopper arm to be stored when the lid is closed.

As can be seen from FIGS. 1 to 3, according to the present invention, the stopper arm 18 has an elastic projection 36 elastically deformable in the contraction direction at an intermediate portion of the hinge side, and has a peripheral portion of the opening. The separation preventing claws 38 that can be engaged with the back surface peripheral edge 32a of the insertion hole 32 are formed on the open / close side sides of the free end portion 18b with respect to the base end 18a.

As the elastic projection 36, for example, a relief hole 40
Can be exemplified, and the width of the bridge-like projection, that is, the width between the hinge side and the open / close side, is increased by elastic deformation accompanied by partial intrusion into the relief hole. Is formed to be able to reduce the width.

As shown in FIG. 3, when the lid 12 is closed, most of the stopper arm 18 is stored in the storage recess 34, and the lid is held in its closed position under the lock of the closing stopper 16. (See FIG. 2). When the lid 12 is closed and the closing stopper 16 is unlocked and the opening / closing side 12b is pulled up, the lid 1
The stopper arm 18 is opened with the pulling of the stopper arm 18 under the rotation in the arrow direction of FIG.

As shown in FIG. 1, the free end portion 18b of the stopper arm is provided with a separation preventing claw 38 which can be engaged with the back surface peripheral edge 32a of the insertion hole. Thus, detachment of the stopper arm from the insertion hole 32 and excessive rotation of the lid in the opening direction are reliably prevented.

Here, in the present invention, since the elastic projection (bridge-like projection) 36 is provided in the middle of the hinge side of the stopper arm 18, the stopper arm 18 is pulled when the lid 12 is opened. The elastic projection is pulled out above the insertion hole 32 under the
engaged with b. The movement (swing) of the link arm 18 at the inclination angle at this time can be regulated so that the insertion hole 32
By setting the width (width in the horizontal direction in the figure) of the stopper arm, the advance of the stopper arm into the storage recess 34 is controlled by the peripheral edge of the insertion hole surface.
Since it is blocked under the engagement of the elastic projection 36 with 32b, this locks the stopper arm, ie the open stopper, whereby the lid 12 is held in its open position shown in FIG.

In the open position of the lid 12, the stopper arm 18, that is, the lid is held only by the engagement of the elastic projection 36 with the peripheral edge 32b of the insertion hole surface. When the lid is pressed in the closing direction, that is, in the direction shown by the arrow in FIG. 1 by a force exceeding the original holding force of the projection, the elastic projection of the elastic projection accompanied by partial intrusion into the relief hole 40 is obtained. Stopper arm 18 in storage recess 34
Progress is guaranteed, and the lid can be closed.

As described above, in the lid opening stopper structure 10 according to the present invention, the elastic projection 36 and the stopper arm 18 provided with the separation preventing claw 38 serve as the opening stopper by using the pivot pin 28 as its base end. The stopper arm is provided on the side of the lid 12 with the pivot 18a, and the free end 18b of this stopper arm is inserted into the storage recess 34 on the armrest body side.
It is only freely inserted through 2. That is, according to the present invention, the open stopper (stopper arm 18) for holding the lid 12 at the open position increases the number of parts,
And it can be easily secured without complicating the configuration.

Then, it is sufficient to pivotally attach the base end 18a of the stopper arm to the bracket 26 of the lid via the pivot pin 28 and insert the free end 18b from the insertion hole 32 into the storage recess 34. In addition, the simplification of the work also improves the workability.

Furthermore, in this configuration, since the pivot point of the stopper arm 18 is only one at the lid side, that is, at the base end 18a, rattling due to the clearance of the pivot point is reliably prevented. it can. Therefore, the stability of the lid 12 at the time of opening is surely improved.

The stopper arm 18 has an elastic projection 36,
And a form having the disengagement preventing claws 38 is sufficient.
From this point, the configuration can be sufficiently simplified.

In this configuration in which the base end 18a of the stopper arm is pivotally connected to the lid 12, the storage recess 34 for the stopper arm 18 when the lid is closed only needs to be provided on the armrest body side. This does not complicate the layout, and further prevents the lid from increasing in size.

Here, in the embodiment of the present invention, the elastic projection 36 of the stopper arm 18 is embodied as a bridge-like projection integral with the stopper arm, but it is sufficient if the elastic projection 36 can be elastically deformed in the reduction direction. For this reason, the present invention is not limited to this. For example, another structure such as a leaf spring may be provided on the stopper arm 18 as an elastic projection. However, if the elastic projection 36 is formed integrally with the stopper arm 18 like the bridge-like projection in this embodiment, the number of components can be reduced and the configuration can be simplified from this point.

In this embodiment, the armrest
Although the open stopper structure of the lid 12 provided in the embodiment 20 is embodied, the present invention is not limited to the armrest, but may be applied to other on-board equipment, for example, a lid of a console box, etc. May be. In addition, if it is a one-sided lid, it is not limited to on-vehicle equipment such as an armrest and a console box,
It goes without saying that the present invention can be applied to lids of any equipment.

The embodiments described above are for explaining the present invention, and do not limit the present invention in any way, and all the modifications and alterations within the technical scope of the present invention are not limited thereto. It goes without saying that it is included in the invention.

[0032]

As described above, according to the lid opening stopper structure of the present invention, only the stopper arm provided with the elastic projection and the separation preventing claw is used as the opening stopper, thereby reducing the number of parts. , And the configuration can be simplified easily.

Since it is sufficient to pivotally connect the base end of the stopper arm to the lid, the workability is improved, and the pivoting point of the stopper arm is only one, so that the clearance of the pivoting point is provided. As a result, it is possible to reliably prevent the occurrence of rattling due to the above, and to improve the stability of the lid when the lid is opened.

Further, since the stopper arm only needs to have a form having an elastic projection and a separation preventing claw, the structure of the stopper arm can be sufficiently simplified from this point.

Since it is sufficient to provide a storage recess for the stopper arm when the lid is closed on the equipment main body side, the layout of the lid is not complicated, and the lid is also reliably prevented from being enlarged. it can.

In addition, if the elastic projection of the stopper arm is formed integrally with the stopper arm as a bridge-like projection, a separate member or the like is not required. Therefore, also from this point, the number of parts can be reduced and the configuration can be simplified. Can be attached.
