Abstract

A safety gate for use in obstructing doorways, passageways and similar openings to restrict the movement of children. The safety gate includes a panel that can be readily secured in and removed from the opening by extending and retracting a bumper mounted on an outer rail of the panel. The bumper is biased to the extended position in a first direction by a spring that is moved in a second direction transverse to the first direction. The gate can include a pair of extendable bumpers and a pair of springs that independently bias the bumpers to the extended position when moved in the transverse second direction relative to the bumpers. The spring can be a leaf spring having one end attached to a drive member, which can be moved in the first direction, and an opposite end that is slidably supported on a surface of the drive member. The panel can include a pair of panels that slide relative to each other to vary the effective width of the gate so as to correspond to the width of an opening within which the gate is to be positioned.

Claims

1. A safety gate for obstructing an opening having a width and a pair of opposing members defining the width, the gate comprising:

at least one panel constructed and arranged to be positioned within the opening, the panel including an outer rail;

first and second bumpers mounted on the outer rail and being movable in a first direction between an extended position and a retracted position, the gate to be secured in the opening when the first and second bumpers are moved to the extended position, the gate to be released from the opening when the first and second bumpers are moved to the retracted position;

a drive member slidably mounted on the outer rail and movable in the second direction the first and second bumpers being coupled to the drive member; and

first and second springs mounted on the drive member adjacent the first and second bumpers and being moveable in a second direction that is transverse to the first direction between a first position and a second position, the first and second springs being constructed and arranged to independently bias, respectively the first and second bumpers toward the extended position when the springs are moved toward the first position in the second direction.

2. The safety gate recited in claim 1, wherein the first and second springs are constructed and arranged to be compressed in the first direction when the springs are moved toward the first position in the second direction.

3. The safety gate recited in claim 2, wherein the first and second springs include a leaf spring.

4. The safety gate recited in claim 2, wherein the at least one panel includes a first panel and a second panel adjustably attached to the first panel so that the gate can be adjusted to correspond to the width of the opening.

5. The safety gate recited in claim 1, further comprising first and second bumper links respectively interconnecting the first and second bumpers to the drive member, the first and second bumper links being pivotally connected to the first and second bumpers.

6. The safety gate recited in claim 1, further comprising a handle pivotally mounted on the panel between a locked position and an unlocked position, the handle being coupled to the drive member to move the drive member toward the first position and toward the second position when the handle is pivoted toward the locked position and the unlocked position respectively.

7. The safety gate recited in claim 6, further comprising a slide link interconnecting the handle to the drive member, the slide link being pivotally connected to the handle and the drive member.

8. The safety gate recited in claim 1, wherein the first direction is perpendicular to the second direction.

9. A safety gate for obstructing an opening having a width and a pair of opposing members defining the width, the gate comprising:

at least one panel constructed and arranged to be positioned within the opening, the panel including an outer rail;

at least one bumper mounted on the outer rail and being moveable in a first direction between an extended position and a retracted position, the gate to be secured in the opening when the at least one bumper is moved to the extended position, the gate to be released from the opening when the at least one bumper is moved to the retracted position; and

at least one spring mounted on the outer rail and being moveable in a second direction that is transverse to the first direction between a first position and a second position, the at least one spring being constructed and arranged to bias the at least one bumper toward the extended position when the spring is moved toward the first position in the second direction, the at least one spring being constructed and arranged to be compressed in the first direction when the spring is moved toward the first position in the second direction, wherein the at least one bumper includes a plunger having a cam surface disposed adjacent the at least one spring, the at least one spring engaging the cam surface when the spring is moved toward the first position.

10. A safety gate for obstructing an opening having at least one vertical member, the gate comprising:

a panel constructed and arranged to be positioned within the opening, the panel including an outer rail;

at least one bumper mounted on the outer rail and being movable between an extended position to be engaged with the vertical member of the opening and a retracted position to be disengaged from the vertical member;

a drive member mounted on the outer rail and being movable between a first position and a second position; and

at least one leaf spring coupled to the drive member and disposed adjacent the at least one bumper, the at least one leaf spring being constructed and arranged to bias the bumper toward the extended position when the drive member is moved toward the first position.

11. The safety gate recited in claim 10, wherein the at least one leaf spring has a generally bell curve shape.

12. The safety gate recited in claim 11, wherein the at least one bumper includes a plunger having a cam surface disposed adjacent the at least one leaf spring, the at least one leaf spring engaging the cam surface when the leaf spring is moved toward the first position.

13. The safety gate recited in claim 12, wherein the at least one leaf spring has an apex that engages the cam surface of the at least one bumper when the leaf spring is moved to the first position.

14. The safety gate recited in claim 12, wherein the at least one bumper includes a first bumper and a second bumper and the at least one leaf spring includes a first leaf spring and a second leaf spring, the first and second leaf springs independently biasing, respectively, the first and second bumpers toward the extended position when the first and second leaf springs are moved toward the first position.

15. The safety gate recited in claim 11, wherein the at least one leaf spring includes a first end and a second end, the first end being attached to the drive member and the second end being slidably supported on a surface of the drive member.

16. The safety gate recited in claim 15, wherein the drive member includes at least one rub rail protruding from the surface, the second end of the leaf spring being supported by the rub rail above the surface of the drive member.

17. The safety gate recited in claim 16, wherein the at least one leaf spring and the at least one rub rail each has a width, the rub rail width being less than the leaf spring width.

18. A safety gate for obstructing an opening having a pair of opposing members, the gate comprising:

a panel constructed and arranged to be positioned within the opening;

engaging means for frictionally engaging one of the opposing members of the opening when the gate is positioned in the opening, the engaging means being mounted to the panel to move in a first direction;

actuating means for moving the engaging means in the first direction, the actuating means being mounted on the panel adjacent the engaging means to move between a locked position and an unlocked position in a second direction that is transverse to the first direction; and

spring means for biasing the engaging means in the first direction against the opposing member when the actuating means is moved toward the locked position, the spring means being mounted on the actuating means to be moved between the locked position and the unlocked position.

19. The safety gate recited in claim 18, wherein the opening and the panel each has a width, the safety gate further comprising adjusting means for adjusting the panel width to correspond to the opening width.

20. The safety gate recited in claim 18, wherein the actuating means includes retracting means for retracting the engaging means away from the vertical member when the actuating means is moved toward the unlocked position.
