- a second restriction portion including a side wall 80 of the handle 70 and a base end surface 61 of the slide restriction portion 60 of the lock piece 50 is provided between the handle 70 and the lock piece 50. Then, as shown in FIG. 11B, when the lock piece 50 is forcibly pressed from the outside, the lock piece 50 comes into contact with the base end surface 61 of the slide restricting portion 60, and the amount of the lock piece 50 is regulated. Is done. Since the pull-in amount is larger than the pull-in amount by the first restricting portion, when the lock pieces 50 and 51 are attached to the back side of the front wall 3a and then mounted with a back panel not shown, both sides of the back panel are mounted. The lock pieces 50 and 51 can be pulled in greatly from the insertion holes formed on the surface until the leading ends of the lock pieces 50 and 51 are inserted, thereby making it easy to mount.
- the rotation of the handle 70 and the rotation of the rotor 20 are restricted by the first restricting portion, and the amount of the lock piece 50 retracted by the first restricting portion is the second amount. Since it is configured to be smaller than the pull-in amount of the lock piece 50 by the restricting portion, the lock pieces 50 and 51 come out from the insertion holes formed on both side surfaces of the back side panel (not shown) of the front wall 3a. Can be prevented.
- FIG. 16 shows another embodiment of the opening / closing body locking device according to the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.
- FIG. 16 shows an enlarged perspective view of the main part.
- a rotor 20a and a handle 70a are integrally formed. That is, the extension pieces 30 and 31 are extended from the substantially opposing positions on the outer periphery of the rotor 20a, and the end portions of the lock pieces 50a and 51a are pivotally attached to the tip portions thereof in the same manner as in the above-described embodiment. Has been.
- a plate-like connecting piece 32 is extended from the outer periphery of the rotor 20a along the rotation axis direction, and the base end side is wide so as to extend from the distal end of the connecting piece 32 toward the outer diameter direction.
- a lever-like handle 70a that is narrow and slightly wider toward the distal end side is connected.
- a support hole 21a into which a rotation shaft (not shown) is inserted is formed at the center of the rotor 20a, and the rotor 20a and the handle 70a are connected to the globe via a support shaft (not shown) inserted into the support hole 21a. It is pivotally attached to the back side of the front wall of the box. Therefore, in this embodiment, the axis C1 of the rotation axis of the rotor 20a and the axis C2 of the rotation axis of the handle 70a are the same.
- the rotor 20a rotates integrally with the handle 70a, and the lock pieces 50a and 51a slide.
- the handle 70a since the handle 70a has a lever shape integrated with the rotor 20a, the number of parts can be reduced to reduce the manufacturing cost, and the length of the handle 70a can be secured. The rotation moment can be increased.
- FIG. 17 and 18 show still another embodiment of the opening / closing body locking device according to the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.
- the locking device 10b (hereinafter referred to as “locking device 10b”) of the opening / closing body in this embodiment has a rotor 20b and a handle 70b as separate bodies, and as shown in FIG.
- the glove box 3A is attached to the upper end of the glove box 3A and pushes down the handle 70b.
- the front wall 3a on the front surface of the glove box 3A is composed of a front panel and a back panel, and a locking device 10b is attached to the inside of the front wall 3a. Further, a part of the handle 70b protrudes substantially at the center of the upper end surface 3c. An operation hole 4 is formed. Further, insertion holes for slidingly supporting the lock pieces 50b and 51b are formed on both sides of the front wall 3a.
- the rotor 20b has a support hole 21a into which a rotor rotation shaft (not shown) is inserted in the center thereof, and a protruding portion 35 is extended obliquely outward from a predetermined position on the outer periphery thereof.
- the handle 70b has an L-shaped main body 71, and a pressing portion 86 that presses the protruding portion 35 of the rotor 20b from the tip of the other end 82 is provided perpendicular to the main body 71. ing.
- a push portion 88 projects from the center of the pressing portion 86.
- the axis C1 of the rotor rotation shaft (not shown) of the rotor 20b and the axis C2 of the handle rotation shaft (not shown) of the handle 70b are parallel to each other.
- the rotor rotation shaft of the rotor 20b and the handle rotation shaft of the handle 70b are parallel to the plane (the upper end surface 3c) including the operation hole 4 of the front wall 3a, and the rotor 20b.
- the handle 70b is attached to the front wall 3a so as to be rotatable along the planes of the front and back panels of the front wall 3a. Further, the push portion 88 of the handle 70b protrudes upward from the operation hole 4 of the front wall 3a so that the push portion 88 can be pushed in.
- this locking device 10b by pushing down the push portion 88 protruding from the operation hole 4 downward, the pressing portion 86 presses the protruding portion 35, and the rotor 20b is rotated, so that the lock pieces 50b and 51b. Is designed to slide. Moreover, in this embodiment, since the operation hole 4 is formed in the upper end surface 3c of the front wall 3a of the glove box 3, when the glove box 3 is seen from the front side, it is not conspicuous and appearance can be improved. .
- the locking device is attached to the glove box that is the opening and closing body, but the locking device can also be attached to the instrument panel that is the attached member.
- the locking device of this embodiment was applied to the structure where the glove box was attached to the opening part 1a of the instrument panel 1 so that opening and closing was possible, for example, a lid could be opened and closed to the opening part of an instrument panel
- the present invention may be applied to an attached structure or the like, and can be widely used for various opening / closing bodies that open and close the opening.
- the two lock pieces are engaged with the engagement holes 1b and 1b provided on the inner surfaces on both sides of the opening 1a of the instrument panel 1, respectively. May be engaged with an engagement hole formed on the upper inner surface or the like of the opening.
- the rotor that is a rotor is directly rotated by a handle that is rotatably attached to the opening / closing body.
- the present invention is not limited to this structure.
- the rotor is a pinion gear, and a rack groove is formed in the other end of each of the pair of lock pieces, and meshed with the pinion gear, the handle is rotated, and one lock piece is slid.
- the pinion gear may be rotated in conjunction with each other and the other lock piece may be slid.
- the rotor is a rotor as in the above embodiment, and a gear groove is formed in a part of the outer periphery of the rotor.
- a gear groove that meshes with the gear groove of the rotor is formed at the tip of the handle. The rotor may be rotated through both gear grooves by rotating the handle.
- a known rotation structure can be employed.
