Abstract
A child-resistant buckle and buckle guard combination is disclosed that relies for its effectiveness on differences in the ways young children and adults think rather than on presumed (but often non-existent) strength or dexterity differences. The child-resistant feature comprises a combination lock mechanism that incorporates at least one directly manipulated member, and, in some embodiments, at least one indirectly movable member. The device is buckled into a conventional safety belt buckle by means of a tongue-like connector. A housing or guard denies access to the push button of the conventional safety belt buckle.
Claims12
A child-resistant buckle and buckle guard combination comprising
- a buckle having a child-resistant feature comprising an actuator button mounted on said buckle, said actuator button having a vertical axis, and a combination lock mechanism having at least one tumbler, said tumbler being rotatable about the vertical axis of said actuator button,
- means for connecting said buckle to a conventional safety belt buckle body,
- means for denying the child access to a conventional safety belt buckle release mechanism;
- and
- wherein the means for denying access to the release mechanism on said conventional safety belt buckle is a guard, said guard forcibly removable from said combination by an adult thereby allowing said adult access to said conventional safety belt buckle release mechanism.
2 more elements
A child-resistant buckle and buckle guard combination comprising
- a child-resistant push-button buckle of the type comprising the elements of a body, a tongue insertable into said body in a direction parallel to the longitudinal axis of said push-button buckle, a latch member attached to said body capable of holding said tongue in said body, a push button mounted above said latch member for releasing said tongue from said body by movement of said latch member, a top cover for said body, means for blocking the movement of said push button and said latch member to positions wherein said tongue is released when said push-button buckle is in the locked, child-resistant condition, said means for blocking being mounted on said push button and means for returning said means for blocking to the locked, child-resistant condition,
- wherein said means for blocking is a rotatable member that is rotatable about an axis perpendicular to the longitudinal axis of said push-button buckle and said means for returning is a spring mounted between said rotatable member and said push button,
- means for connecting said buckle to the body of a conventional safety belt buckle, and
- means for denying access to the release mechanism on said conventional safety belt buckle.
1 more element
A child-resistant buckle and buckle guard combination comprising
- a push-button buckle of the type comprising the elements of a body, a tongue insertable into said body in a direction parallel to the longitudinal axis of said push-button buckle, a latch member attached to said body capable of holding said tongue in said body, a push button mounted above said latch member for releasing said tongue from said body by movement of said latch member, a top cover for said body, means for blocking the movement of said push button and said latch member to positions wherein said tongue is released when said push-button buckle is in the locked, child-resistant condition, said means for blocking being mounted on said top cover and means for returning said means for blocking to the locked, child-resistant condition
- wherein said means for blocking is a rotatable member that is rotatable about an axis perpendicular to the longitudinal axis of said push-button buckle and said means for returning is a spring mounted between said rotatable member and said top cover,
- means for connecting said buckle to the body of a conventional safety belt buckle, and
- means for denying access to the release mechanism on said conventional safety belt buckle.
1 more element
A child-resistant buckle and buckle guard combination comprising
- a buckle improved to provide child resistance having a body, a latch positioned in said body and held captive therein, said latch movable between a latched position and an unlatched position, spring means contacting said latch biased to move said latch to said latched position, operator means operable to move said latch to said unlatched position, and a cover mounted to said main body and enclosing said latch, said spring means and said plate, said cover including means securing said cover to said body, at least one first means for preventing the motion of said operator means when said first means for preventing is in at least one position, said first means for preventing being rotatably attached to said cover and accessible to direct manual manipulation, and at least one means for returning said means for preventing to said at least one position in the absence of manual manipulation of said first means for preventing, at least one second means for preventing the motion of said operator means when said second means for preventing being rotatably attached to said cover and inaccessible to direct manual manipulation, and at least one position in the absence of manual manipulation of said first means for preventing,
- means for connecting said buckle to the body of a conventional safety belt buckle, and
- means for denying access to the release mechanism on said conventional safety belt buckle.
