Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a locking mechanism for a storage section of an interior component such as an automobile seat.

(Prior art) The conventionally known specification and drawings of Japanese Utility Model Application No. 1982-124770 and drawings (Japanese Utility Model Application No. 56-42444) disclose a front-opening storage chamber and an opening/closing body for opening and closing the opening of the storage chamber. , discloses a knob attached to the opening/closing body.

Furthermore, Japanese Utility Model Publication No. 50-31360 discloses a striker and a locking member, and the locking member is
A locking mechanism is described that is formed by an elastic rod that is fixed at both ends and has an approximately 3/4-arc retaining portion in the center.

(Problems to be Solved by the Invention) However, the technique described in the above-mentioned Japanese Utility Model Publication No. 56-42444 is only a storage section, and does not disclose a locking mechanism at all.

The locking spring described in the above-mentioned Japanese Utility Model Publication No. 50-31360 is the middle part of a locking spring whose both ends are fixed by a support shaft 2 (the part names and codes listed in this column are those listed in the publication). It has a structure in which an arcuate piece 3 is formed at the end, a flange 3a is formed at the open end of the arcuate piece 3, and a bar-shaped engagement piece is locked to the arcuate piece 3 thus formed. In this structure, the arcuate piece 3 that the rod-shaped engagement piece engages is fixed on the support shaft 2 via the locking spring, resulting in a structure that generates vibration in the insertion direction, making it difficult to install it in the vehicle. In this case, the engaging piece is attached to the opening/closing body and the arcuate piece 3 is provided on the storage chamber side, and the vibration peculiar to the vehicle causes the engaging piece to be in a floating state, which may cause the contact between the opening/closing body and the storage chamber side. There is a problem that an unpleasant sound such as a rattling sound is generated between the two.

Furthermore, looking at the relationship between the inner diameter of the arcuate piece 3 and the outer diameter of the engagement piece, the inner diameter of the arcuate piece 3 is much larger than the outer diameter of the engagement piece. There is also a problem in that rattling noise occurs between the arcuate piece 3 and the engagement piece.

Further, in the above-mentioned known example, the lock can be released by simply pulling the arcuate piece 3 apart from the engaging piece without opening the arcuate piece 3, which is elastically engaged with the engagement piece. In this case, since the structure is such that both the locking spring and the other engaging piece are held and pulled apart, tensile force acts on both the locking spring and the engaging piece, and a load is placed on both mounting parts. There is a problem in that the attachment part becomes loose and damaged.

To solve the above problem, the inner diameter of the arcuate piece 3 and the outer diameter of the engagement piece are made the same so that they are engaged without any gaps, thereby preventing rattling noises when the lock is engaged, and when unlocking, the arcuate piece 3 The structure is such that the engaging piece is removed after opening.
It is best to prevent the attachment from becoming loose or damaged.

(Object of the Invention) Therefore, an object of the present invention is to prevent rattling noise when the holding part and the striker are engaged, and also to prevent loosening and damage of the attachment part on the holding part side. This is what I did.

(Means for Solving the Problems) Therefore, the present invention provides a storage chamber 4 provided in an automobile interior part 1 and partially opening into the vehicle interior, a striker 12 provided on the side of the storage chamber 4, and a base portion. It consists of an opening/closing body 5 whose side is pivoted to the storage chamber 4 to open and close the opening of the storage chamber 4, and a locking member 11 which engages with the striker 12 provided on the free end side of the opening/closing body 5, The locking member 11 includes a holding part 17 that opens and closes elastically and has an inner diameter substantially equal to the outer diameter of the striker 12 and an opening smaller than the outer diameter of the striker 12; The holding portion 17 is formed of an inclined opening 18 formed at the opening end and expanding inwardly in a divergent shape, and a grip 15 integrally connected to the outer side of the inclined opening 18. The engaging direction is fixed at a position facing the striker 12 inside the opening/closing body 5, and the free end 14 of the grip 15 is exposed through a window hole 22 formed in the opening/closing body 5 so as to be operable with a fingertip. This is a locking mechanism for a housing section for automobile interior parts that protrudes toward the side.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 indicates a rear seat which is one of the interior parts of an automobile, and a storage chamber 2 in the lower front side of the rear seat 1 stores parts such as an umbrella. will be established.

As shown in FIGS. 2 and 3, the storage room 2 is

The side surface of the opening/closing body 5 is approximately triangular and is shaped like a container, with a front wall 6 and a bottom wall 7 connected in an L-shape, and side walls 8, 8 attached to both sides of the front wall 6 and bottom wall 7.
It has dimensions that can accommodate articles 23 such as umbrellas,
It is made of plastic.

The side walls 8, 8 of the opening/closing body 5 are provided with shafts 9, 9 that protrude laterally, and the shafts 9, 9 rotate the frame 10 of the storage chamber 2 between the closed state and the open state.
It is attached to the shaft.

A locking member 1 is mounted on the upper part of the front wall 6 of the opening/closing body 5.
1 is fixed. The locking member 11 is connected to the storage chamber 4.
It engages a striker 12 attached to the upper frame 10 of. The striker 12 is fixed to the upper wall in the storage chamber 4 and has a substantially U-shaped side surface, and the lower part of the front rod 13 is formed from a round bar with a circular cross section parallel to the front wall 6 of the opening/closing body 5. Engagement part 2
5, the locking member 11 and the engaging portion 25 are arranged at right angles, so that even if the mounting position of the locking member 11 is slightly shifted vertically, the locking member 11 is always engaged accurately under the same conditions.

Except for FIG. 8, the locking member 11 is entirely made of plastic and has a shape similar to the letter M in plan view. That is, the end portions are two parallel grips 15, 15 with free ends 14, 14, and 3/
A holding part 17 formed of an elastic member having a four-arc shape and an inner diameter substantially equal to the outer diameter of the engaging part 25.
It has a clamping part 16 having a. The holding part 17
engages with the front rod 13 of the striker 12.

A slanted opening 18 that gradually opens to a wider end is formed at the open end of the holding portion 17, and the slanted opening 1
The grip 15 is connected to the tip of the grip 8.

The upper part of the front wall part 6 of the opening/closing body 5 is provided with screws 19, 19 that protrude inwardly, and window holes 22 are provided on both sides of the screws 19, 19.
is formed. A collar 24 is provided at the lower part of the holding part 17.
The flange 24 is formed with an insertion hole 20 through which the screw 19 is inserted, and a nut 21 is screwed onto the head of the screw 19 to fix it in an immovable state in the direction of engagement.

The grips 15, 15 are loosely passed through the window holes 22, 22 and protruded forward so that the protrusions can be grasped with the fingertips, and when the grips 15, 15 are grasped with the fingertips, the holding portion 17 opens.

Although the embodiment in which the material of the lock member 11 is made of plastic has been described above, it is possible to manufacture it from a metallic elastic material. Furthermore, when made of plastic, the locking member 11 and the opening/closing body 5 can be integrally formed.

The opening/closing body 5 is not limited to the shape of the embodiment, but may be a simple lid type or a drawer type.

Furthermore, the interior parts for automobiles are not limited to seats, but may be any part that can form a storage room, such as a glove box.

Another embodiment of the locking member 11 is shown in FIG. Compared to the previous example, there is only one grip 15. However, the object of the present invention, the holding part 1
7 and the striker 12 in the engaged state, and prevention of loosening and damage of the attachment part on the holding part 17 side can be similarly expected.

The unlocking operation in Fig. 8 is performed using grip 1.
This is done by pulling 5. When the grip 15 is pulled, the holding part 17, although only on one side, expands and the striker 12 is easily released, as in the previous embodiment. Therefore, rattling noise in the engaged state is prevented, and the attachment part on the holding part 17 side is not loosened or damaged. In the case of FIG. 8, an integral pin 26 is formed in the holding part 17, and the tip of the pin 26 is enlarged. Installed.

When the opening/closing body 5 is opened as shown in FIG. 3 and the article 23 is stored in the storage chamber, and the opening/closing body 5 is closed as shown in FIG. 2, the desired article can be stored.

In order to open the opening/closing body 5, as shown in FIG.
5 moves within the window holes 22, 22 and opens the inclined opening 1.
8 and the holding part 17 are enlarged, and when they are opened larger than the outer diameter of the engaging part 25 of the striker 12, they are disengaged from the engaging part 25, and the opening/closing body 5 rotates in the direction of arrow A in FIG. Since the door is opened, articles 23 such as umbrellas can be taken in and out freely. in this way,
Since the holding part 17 is opened and removed, loosening and damage of the attachment part on the holding part 17 side is prevented.

When closing the opening/closing body 5, use the grip 15,
15 and the opening/closing body 5, and when it is closed as it is in the direction of arrow B in FIG. The holding part 17 engages, but since the outer diameter of the engaging part 25 and the inner diameter of the holding part 17 are equal and are in a right-angled relationship, they engage tightly.
Rattling noise during engagement is prevented and there is no rattling.

(Effects) The technique described in the above-mentioned Japanese Utility Model Publication No. 56-42444 is only a storage chamber, and does not disclose a locking mechanism at all. Also, the above-mentioned Jikoaki
The arcuate piece described in Publication No. 50-31360 (corresponding to the holding part of the present application) is formed in the middle part of a locking spring that locks both ends, and an engaging piece (corresponding to the striker of the present application) is attached to the arcuate piece. Since the arcuate piece has a structure that vibrates in the insertion direction, when installed in a vehicle, the engagement piece is attached to the opening/closing body and the arcuate piece is provided on the storage chamber side. There is a problem in that the engaging piece becomes floating due to the vibrations peculiar to the vehicle, and as a result, an unpleasant sound such as a rattling sound is generated between the opening/closing body and the storage chamber side. Further, since the inner diameter of the arcuate piece is formed to be much larger than the outer diameter of the engagement piece, there is a problem in that rattling noise is also generated between the arcuate piece and the engagement piece. In addition, the lock in the above-mentioned known example is released without opening the arcuate piece, and because the structure is such that the two are separated as they are, the locking spring on one side and the engaging piece on the other side are both held and pulled apart, which puts a burden on the mounting part. As a result, there is a problem in that the attachment portion becomes loose and damaged.

However, the present invention provides a storage chamber 4 provided in an automobile interior part 1 with a portion opening into the vehicle interior, a striker 12 provided on the side of the storage chamber 4, and a striker 12 whose base side is pivoted to the storage chamber 4. an opening/closing body 5 that opens and closes the opening of the storage chamber 4; and a locking member 1 that engages with the striker 12 provided at the free end of the opening/closing body 5.
1, the locking member 11 has an inner diameter substantially equal to the outer diameter of the striker 12 and an opening that is smaller than the outer diameter of the striker 12 and is elastically opened and closed; It is formed by an inclined opening 18 formed at the open end of the holding part 17 and expanding inwardly in a divergent shape, and a grip 15 integrally connected to the outer side of the inclined opening 18,
The holding portion 17 is fixed immovably in the engagement direction at a position inside the opening/closing body 5 facing the striker 12, and the free end 14 of the grip 15 is connected to a window hole 22 formed in the opening/closing body 5. This is a locking mechanism for a housing section for automobile interior parts that is protruded outward so that it can be operated with a fingertip.
Since it is fixed to the opening/closing body 5 in an immovable state in the engagement direction, rattling noise between the opening/closing body 5 and the storage chamber 4 side is not generated even if vibrations peculiar to the vehicle occur.

(b) Since the inner diameter of the holding portion 17 is approximately equal to the outer diameter of the striker 12, the engagement is tight and no rattling noise is generated.

C. Also, since the lock is released by opening the holding part 17, it can be easily removed.
Moreover, no load is placed on the mounting part of the striker 12, and loosening and damage of the mounting part are prevented.

D. Also, since the structure is simple, it is easy to manufacture, easy to install, and can be done at low cost.

This effect is achieved.
