Abstract

PROBLEM TO BE SOLVED: To prevent damage to a design surface in assembling to stabilize the quality and enable common use for locks of various-shaped door panels for cost reduction.SOLUTION: A control knob 2 and a link member 4 are integrated to form a knob unit 1, and the knob unit 1 is fixed to a door panel.

Description

  The present invention is provided in a door panel that opens and closes an opening of a storage box, and a lock bar extending in the left-right direction with respect to the front view of the door panel is engaged with an engagement hole formed in a side wall of the storage box to close the door panel. The present invention relates to a bowl-shaped side lock device that is held in a state and that opens a door panel when a lock bar is removed from an engagement hole.

  A side lock device is disposed in a grab box for a vehicle. This side lock device locks the door that opens and closes the opening of the grab box to the grab box and restricts the door from opening during vibration or sudden acceleration / deceleration.

  A general side lock device has a swingable operation knob and a pair of left and right lock rods that can slide in opposite directions, and is attached to a door (for example, see Patent Document 1). . The two lock bars are urged in a direction protruding toward the side wall of the box body. The tip of each lock bar engages with an engagement hole formed in the left and right side walls of the box body. For this reason, the door can maintain the state locked to the box main body.

  When the lower end of the operation knob is pulled, for example, to swing, the two lock bars slide away from the box body, and the engagement between the lock rod tip and the box body is released. For this reason, the lock is released, the door is movable with respect to the box body, and the box body can be opened.

  Conventionally, it has been considered that it is better to operate the two lock rods independently as a countermeasure against a lock failure. This is because even if one of the lock bars does not operate, the door can be locked to the box body if the other lock bar operates. However, in order to operate the two lock bars independently, many parts are required for transmitting the swing of the operation knob to each lock bar. For this reason, there is a problem that it is difficult to reduce the manufacturing cost of the side lock device.

  When the two lock rods are operated independently, only one lock rod may be engaged with the engagement hole due to the door being displaced with respect to the box body. In this case, since the door is locked to the box body with the position shifted, a large force is applied to the side lock device or the door, and the side lock device or the door may be deformed. Therefore, in recent years, there has been a demand for a side lock device in which the left and right lock rods operate synchronously.

  Japanese Patent Application Laid-Open No. 2009-235794 proposes a side lock device in which two lock rods operate in synchronization to reduce manufacturing costs. In this side lock device, a link member that is rotated by an operation of an operation knob is disposed, and a pair of left and right lock rods are held on a pair of link shafts that are formed to protrude from the rotation shaft of the link member. Therefore, only by operating the operation knob, the pair of left and right lock bars can be moved synchronously to release the lock.

Japanese Patent No. 3863837 JP 2009-235794 A

  However, in the side lock device described in Patent Document 2, it is necessary to assemble a relatively small operation knob, an operation knob urging spring, a link member, etc. to a relatively large door panel, and the assembly workability is poor. There was a problem. In addition, there is also a problem that the design surface of the door panel or the operation knob is easily damaged during assembly.

  Furthermore, the angle of the link member with respect to the door panel has to be adjusted to a predetermined position, and it has been difficult to stabilize the assembly quality. Also, in order to hold the operation knob and the link member, it is necessary to form a predetermined holding structure on the back side of the door panel, but since the door panel has various designs depending on the vehicle model, the holding structure is undercut. Is difficult to integrally mold with the door panel, resulting in high manufacturing costs.

  The present invention has been made in view of such circumstances, and solves the problems described above by forming a unit in which the operation knob and the link member are integrated, and fixing the unit to the door panel. It should be a challenge.

A feature of the side lock device of the present invention that solves the above-described problem is that the lock panel is provided on the door panel that opens and closes the opening of the storage box, and a lock bar extending in the left-right direction with respect to the front view of the door panel is formed on the side wall of the storage box. A hook-shaped locking device that holds the door panel in a closed state by engaging with the joint hole, and opens the door panel by removing the lock bar from the engaging hole,
A base member fixed to the door panel;
An operation knob having a design surface and a pressing portion formed on the opposite side of the design surface, and being held by the base member so as to be relatively movable in a direction approaching and away from the base member;
The rotating shaft has a rotating shaft, a link shaft extending from the rotating shaft and holding one end of the lock rod at an end thereof, and a pressed portion extending from the rotating shaft and engaged with the pressing portion. A link member rotatably held by the base member,
A link urging means for urging the link member in a direction in which the lock rod engages with the engagement hole, and a knob unit integrally formed;
When the operation knob moves relatively in the direction close to the base member, the pressing portion engages with the pressed portion and the link member rotates against the urging force of the link urging means to engage the lock rod. The door panel is out of the hole and opens the opening.

  According to the side lock device of the present invention, the knob unit is fixed to the door panel by forming the knob unit in which the base member, the operation knob, the link member, and the link urging means are integrated, and fixing the base member to the door panel. ing. Therefore, it is easy to assemble the side lock device to the door panel, and it is possible to prevent the design surface of the door panel from being damaged.

  Moreover, since it is not necessary to form a holding part etc. in the back surface side of a door panel, a knob unit can be easily hold | maintained also to the door panel of various design shapes. Therefore, a single knob unit can be shared by a plurality of vehicle types, and a significant cost reduction can be achieved.

  It is desirable that the base member has a locking portion that locks the link member rotated around the rotation shaft against the urging force of the link urging means at a predetermined rotation angle position. If it does in this way, it can be set as the knob unit by which the link member was hold | maintained in the predetermined | prescribed rotation angle position, The operation | work which adjusts the angle of a link member at the time of fixing to a door panel becomes unnecessary, and workability | operativity is improved significantly. .

It is the principal part perspective view which partially fractured | ruptured the grab door with the knob unit used for the side lock apparatus which concerns on one Example of this invention, and was seen from the surface side.

  The side lock device of the present invention includes a storage box, a door panel that opens and closes the opening of the storage box, a lock bar, and a knob unit. Examples of the storage box include a grab box, an accessory case, a console box, and the like, and conventional ones can be used as they are. Also, the door panel and the lock rod can be the same as the conventional one. It is desirable to provide a pair of left and right lock bars, but only one of them may be used.

  The greatest feature of the present invention is the knob unit. The knob unit includes a base member, an operation knob, a link member, and link urging means. The base member is fixed to the door panel while holding the operation knob, the link member, and the link biasing means, and forms the base of the knob unit.

  The operation knob has a substantially plate shape and has a design surface and a pressing portion formed on the side opposite to the design surface. The design surface is usually a surface that is integrally continuous with the surface of the door panel, and is generally a design surface similar to the design surface of the door panel. The pressing portion is a portion that engages with a pressed portion of a link member described later when the operation knob is pressed, and has a columnar shape or a protruding shape. The operation knob is held by the base member so as to be relatively movable in a direction close to and away from the base member, and is relatively moved in a direction close to the base member when operated by a person. The operation knob may be swingably held on the base member, or may be held slidably. For example, when the upper end portion and the lower end portion are held so as to be swingable, the operation knob can be swung by pushing the upper end portion or pulling the lower end portion, so that the upper end portion approaches the base member. It can be moved relative. Therefore, if the pressing portion is formed on the upper end side from the swing shaft, the link member can be rotated by the engagement between the pressing portion and the pressed portion, and the lock can be released.

  It is desirable that the design surface of the operation knob is continuous with the design surface of the door panel when not being operated. Therefore, it is desirable to automatically return to the original position after the operation. Although this action can be achieved by a biasing force of a link biasing means described later, it is desirable that the base member has a knob biasing means for biasing the operation knob in a direction away from the base member.

  This knob urging means urges the operation knob in a direction away from the base member, and enhances the designability with the design surface and the design surface of the door panel as a continuous surface in a state where the operation knob is not operated, Prepare for the next operation of the control knob. A coil spring is desirable, but a leaf spring, rubber, sponge, etc. can also be used.

  The link member has a rotation shaft, a link shaft extending from the rotation shaft and holding one end portion of the lock rod at an end thereof, and a pressed portion extending from the rotation shaft and engaged with the pressing portion, It is rotatably held on the base member by a rotating shaft. One end of the lock bar is held at the end of the link shaft, and the other end of the lock bar is detachably engaged with an engagement hole formed in the side wall of the door panel. Although one link shaft may be used, it is desirable to form two link shafts symmetrically with respect to the rotation shaft. By doing in this way, by moving the link member by holding the pair of lock rods on the pair of link shafts, respectively, the moving directions of the pair of lock rods are opposite to each other. The pair of left and right engagement holes can be engaged and disengaged. Therefore, the stability of the door panel when locked is improved. In this case, the pressed part is preferably formed between the pair of link shafts.

  When the operation knob is operated, the pressed portion is engaged with a pressing portion formed on the side opposite to the design surface, whereby the link member is rotated. For example, if a tapered protrusion-shaped pressing portion whose diameter decreases toward the tip is engaged, the pressed portion moves in a direction perpendicular to the advancing direction of the pressing portion as the pressing portion advances, thereby the link member Can be rotated.

  The link biasing means biases the link member in a direction in which the lock rod engages with the engagement hole. By doing in this way, it can prevent that a door panel opens in the state which is not operating the operation knob. In addition, moderate resistance can be sensed when unlocked, and the operation feeling is good. As described above, the link member is rotated by the urging force of the link urging means when the operation knob is released without using the knob urging means. It is also possible to make a relative movement away from the direction.

  In order to detachably engage the lock rod with the engagement hole, the operation distance of the operation knob, the rotation distance of the link member due to the engagement between the pressing portion and the pressed portion, the movement distance of the lock rod, Balance is important, and the initial position of the link member is uniquely determined. However, holding the link member on the base member so as to be in the initial position is not easy and workability is poor. Therefore, it is desirable that the base member has a locking portion that locks the link member rotated around the rotation shaft against the urging force of the link urging means at a predetermined rotation angle position. By designing the position of the link member that is locked by the locking portion to be the initial position, the link member can be easily set to the initial position.

  The base member is preferably formed in a symmetrical shape and has a pair of left and right holding portions that rotatably hold the pair of link members. In this way, the knob unit can be shared with the operation knobs of the grab doors formed on the right-hand drive car and the left-hand drive car only by changing the position of the holding part held by changing the shape of the link member. can do.
