Description

  The present invention relates to a locking device for an opening / closing body that moves in a wing manner or a sliding manner to open and close an opening of an article storage chamber.

  As a locking device for holding the closing position of the opening / closing body that moves in a wing manner or sliding manner to open and close the opening of the article storage chamber, a pair provided in the casing so as to be able to protrude and retract from both left and right end faces And an operation member attached to the casing so as to be movable in a direction substantially perpendicular to the direction in which both lock pins protrude and project, and an inclined cam surface is formed between the lock pins and the operation member so as to face each other. It is known that when the operation member is pushed in, a pair of lock pins are simultaneously moved in the immersion direction by the joining relationship of the inclined cam surfaces (see Patent Document 1).

On the other hand, in the case of a wide article storage room lid such as a glove box provided on an instrument panel of a car, it is more stable to lock both sides in the width direction than to lock only the center part of the lid. . In addition, there are cases where there is a desire to increase the length of the operating member due to the convenience of the design, but from the viewpoint of usability, it is configured so that the lock can be released by pressing anywhere in the longitudinal direction of the operating member. It is preferable to do.
JP 2004-324201 A

  However, as the length of the operation member is increased, it is difficult to configure the operation member to move straight even if the pushing force is biased. For example, when only one side of the operation member in the longitudinal direction is pressed, Further, there is a possibility that a release failure may occur such that only the pressed side is immersed and only one side of the lock member is unlocked.

  The present invention has been devised to eliminate such inconveniences, and its main purpose is to increase the longitudinal dimension of the operating member by increasing the spacing between the plurality of locking members. Another object of the present invention is to provide a locking device for an opening / closing body configured such that a plurality of locking members are surely synchronized to perform a releasing movement.

  In order to solve such a problem, according to claim 1 of the present invention, in order to convert the pushing force of the operating member into the unlocking motion of the locking member, an inclined cam surface that is opposed to the pressing portion provided on the operating member is provided. In the locking device of the opening / closing body provided in the locking member, the locking member has two members (3a and 3b) moving in opposite directions to each other, and the pressing portion (the convex portions 17a and 17b of the push button 4) and the inclined cam surface Are provided at a plurality of locations in the respective moving directions of the two lock members, and the portions (drive portions 6a and 6b) provided with a plurality of inclined cam surfaces (12a, 12b, 12c and 12d) of the two lock members. ) Are arranged adjacent to each other so as to be relatively movable. According to a second aspect of the present invention, the pressing portion is provided at both ends in the longitudinal direction of the operation member, and the inclined cam surfaces of the two lock members are provided at both ends in the longitudinal direction of the operation member. It shall be provided in the position corresponding to a part.

  According to the present invention configured as described above, the inclined cam surfaces are provided at the positions corresponding to the both end portions of the push buttons in the two lock members. Any one of the pressing portions provided at both end portions of each of the members is joined to the corresponding inclined cam surface. As a result, the two locking members always move synchronously. Therefore, since a special synchronization mechanism such as a link is not necessary, it is possible to achieve a great effect in ensuring the unlocking operation without complicating the structure.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a single view of a locking device for an opening / closing body to which the present invention is applied. The locking device 1 is provided at an end portion on the swing side of a lid that performs an opening and closing movement like a glove box of an automobile, for example, or an end portion on a door-to-door side of a sliding door. A casing 2 having a generally rectangular tube shape with both ends fixed to each other, two lock members 3a and 3b slidably mounted in opposite directions in the casing 2, and a central portion of the casing 2, The push button 4 is provided so as to be movable in a direction perpendicular to the sliding direction of the lock members 3a and 3b. Each of these members is formed, for example, by injection molding of a synthetic resin material.

  As shown in FIG. 2, the two lock members 3 a and 3 b are symmetrical with each other, and the locking claws 5 a and 5 b protruding from the side end open surface of the casing 2 and the sliding portions facing each other at the center portion of the casing 2. It consists of drive parts 6a and 6b arranged adjacent to each other and connecting parts 7a and 7b for connecting the lock claws 5a and 5b and the drive parts 6a and 6b to each other. Among these, the lock claws 5a and 5b are appropriately fitted so as to be engaged with holes 8a and 8b provided in the fixed body F such as an opening of an article storage chamber where the lid is closed or a guide rail of a slide door. It is formed in a shape, and the connecting portions 7a and 7b are set to an appropriate length so as to correspond to the width of the lid or door.

  The parts related to the essence of the present invention are mainly the drive parts 6a and 6b. The drive units 6a and 6b will be described in detail below with reference to FIGS.

  The drive portions 6a and 6b are respectively formed by U-shaped return spring force acting portions 11a and 11b, and inclined cam surfaces 12a, 12b, 12c, and 12d formed on both sides of the return spring force acting portions 11a and 11b. The drive portions 6a and 6b of the two lock members 3a and 3b are slidably joined so that the two return spring force acting portions 11a and 11b can move relative to each other from a position where they are aligned with each other. Yes. The two lock members 3a and 3b are defined by their protrusions 13a, 13b, 14a, and 14b that abut against each other and provided between the casing 2 and prevent the lock members 3a and 3b from coming off the casing 2. Has been made.

  The inclined cam surfaces 12a, 12b, 12c, and 12d are provided on both sides in the longitudinal direction with the return spring force acting portions 11a and 11b sandwiched between the lock members 3a and 3b, and the two cam surfaces are inclined. And the inclination directions of the cam surfaces of the lock members 3a and 3b are opposite to each other (12a = 12b) ≠ (12c = 12d).

  Leaf springs 15a and 15b for individually applying spring force to the inner surfaces of the side walls of the return spring force acting portions 11a and 11b of the lock members 3a and 3b are fixed to the bottom surface of the central portion of the casing 2. The plate springs 15a and 15b are always elastically biased in the direction in which the two lock members 3a and 3b project the lock claws 5a and 5b from the casing 2.

  A horizontally long push button 4 is mounted in a guide opening 16 provided in the center of the upper wall of the casing 2 so as to be vertically displaceable. Although not shown in the figure, the push button 4 is prevented from coming off upward by appropriate means.

  Protrusions 17a and 17b extending downward are provided on the lower surfaces of the left and right end portions of the push button 4, and a guide rod 18 is suspended from the lower surface of the central portion so that the upper wall of the casing 2 and the push button A compression coil spring 19 wound around the guide rod 18 is contracted between the inner surface of 4. As a result, the push button 4 is always urged and bulleted upward.

  When the drive portions 6a and 6b of the two lock members 3a and 3b face each other and the pair of inclined cam surfaces intersect each other, the inclination directions of the pair of inclined cam surfaces are opposite to each other. These portions are V-shaped when viewed from the front. And the front-end | tip of a pair of convex part 17a * 17b suspended from the lower surface of the right-and-left both ends of the pushbutton 4 is contact | abutting to the bottom part of these V-shaped parts.

  Next, the operating procedure of the device of the present invention will be described.

  When the push button 4 is pushed down, the two pairs of inclined cam surfaces (12a, 12c) and (12b, 12d) provided on each of the two lock members 3a, 3b are in contact with the pair of convex portions 17a, 17b. The horizontal component force due to the downward force acting on each tip acts on both inclined cam surfaces (12a, 12c), (12b, 12d), and the two lock members 3a, 3b are both drawn into the casing 2.

  Here, since the pair of convex portions 17a and 17b are suspended from both end portions of the push button 4, only one of the convex portions 17a and 17b is inclined downward so that the inclined cam surfaces (12a and 12c) and (12b and 12d) are in contact therewith. Is pushed out, and the two lock members 3a and 3b are both slid inwardly. That is, with this structure, even if the operating force acting on the push button 4 is biased to one side in the longitudinal direction and the push button 4 is inclined, the two lock members 3a and 3b always move inward by an equal amount in synchronization. Thus, the unlocking is surely performed. Needless to say, the device of the present invention can be used regardless of whether the longitudinal direction is vertical or horizontal.

  The opening / closing body locking device according to the present invention can be widely applied as a locking device for holding all opening / closing bodies in a closed position, such as automobile glove boxes, console lids, wing doors, and sliding doors.
