The present invention relates generally to a gate, particularly to a safety gate for the inside of a residence, and specifically to such a safety gate that requires two steps to open.
Children have boundless curiosity. Children can figure out how things work without books. For example, given time, a child can figure out how a gate works so that he or she can get to the other side or so that the dog can be let in. However, a child, especially a toddler, lacks physical strength.
Adults and teenagers are too busy and have little time. While a dog may move out of the master's path, a gate does not. A gate must be dealt with. If a gate is difficult to manage, then the gate will be removed or left open. If a gate is made easy to open and easy to close, then the chances are maximized that the adult or teenager will keep the gate closed to keep the children safe from falling down the stairs or to keep the dog in or out.
A feature of the present invention is a two-action gate that requires two steps to open. One step is a sliding of a latch with the thumb and the second step is a lifting of the gate with the remainder of the hand to free up a double stop while the latch is retained in an open position with the thumb. Thus, only one hand is required to manage the gate to make the gate easy to open and easy to close.
Another feature of the present invention is the weight of the gate. The gate is preferably relatively heavy from the standpoint of a toddler. A toddler may be able to manage the sliding of the latch. However, a toddler may not be able to manage to lift the gate so as to free up the double stop. The chances are fewer yet that the toddler can keep the latch open with one hand and lift the gate with the other hand. The material of the gate is preferably metal such as stainless steel.
Another feature of the present invention is that one control mechanism, the latch, for keeping the gate closed is positioned at an upper portion of the gate, and that another feature of the invention, the double stop, for keeping the gate closed is positioned at a lower portion of the gate such that the gate includes a two point connection when closed. When closed and pushed against, the gate remains square in its frame without any swaying or twisting.
An advantage of the present invention is that chances are maximized that a toddler cannot open the gate. The two-action or the two steps in combination provide difficulty for the child.
Another advantage of the present invention is that chances are maximized that older people in the household, such as adults and teenagers, will keep the gate closed. The two-action or two steps in combination are easily managed with one hand by a teenager or adult.
Another advantage of the present invention is that the gate is simple and inexpensive to manufacture.
As shown in
Outer frame 12 generally includes a first side portion 20, a second side portion 22 and a lower portion 24. More specifically, each of the side portions 20, 22 of the outer frame 12 includes an upper structural member 26 that extends generally horizontally, a lower structural member or member portion 28 that extends generally horizontally, an outer or first structural member 30 that extends generally vertically and is engaged, such as by welding, to and between the members 26 and 28, and an inner or second structural member 32 that extends generally vertically and is engaged, such as by welding, to and between the members 26 and 28.
Outer frame 12 further includes, as part of the side section 22, an inner structural member 33 that extends generally vertically to and between the upper member 26 of side section 22 and lower member 28. Inner member 33 is referred to as the axis of the gate 14. Gate 14 is journaled upon inner member 33. Inner member 33 is fixed to lower member 28 via a pin and extends into upper member 26 via an opening in which inner member 33 frictionally fits.
Outer frame 12 is a compression frame. Outer frame 12 and gate 14 are disposed generally in a plane. Each of the side portions 20 and 22 includes an upper portion that includes the horizontally extending member 26. The upper portions, including members 26, are relatively drawable to and away from each other in such plane and such upper portions are biased away from each other such that, when the upper portions are drawn together, the outer frame 12 is compressed. This compression is maintained when male members 34 are engaged in female members in an exterior frame or apparatus, where such exterior frame or apparatus is part of a partition or barrier or where such exterior frame or apparatus extends from opposing walls or opposing portions of a door frame. Upper male members 34 extend from and are integral and one-piece with upper member 26. Lower male members 34 extend from and are one-piece with lower member 28. To provide such a compression, one or more of the side portions 20, 22 may be manufactured so as to be slightly oblique relative to the lower portion 24 of the outer frame 12. It should be noted that the four male members or four points of connection 34 may alternatively be female members, or the four points of connection may include a combination of male and female members.
Members 26 and 28 run generally parallel to each other when the outer frame 12 is compressed. Side portions 20 and 22 run generally parallel to each other when the outer frame 12 is compressed. Members 20 and 32 run generally parallel to each other when the frame is compressed or in an uncompressed state.
Upper horizontally extending member 26 is a cylindrical tube. Lower horizontally extending member 28 is tubular and in vertical section takes the form of a rectangle.
Outer or first vertical member 30 can be a tube or a rod. Inner or second vertical member 32 is a tube. Inner member or axis 33 can be a tube or rod.
Outer frame 12, including members 26, 28, 30, 32 and 33, is preferably formed of a metal. Of the metals, stainless steel is preferred. If desired, aluminum may be used.
Gate 14 includes its own frame 36. Gate frame 36 includes an upper structural member 38 extending generally horizontally, a lower structural member 40 extending generally horizontally, a first end vertical structural member 42 extending generally vertically and engaged between the upper and lower members 38 and 40, and a second end vertical structural member 44 extending generally vertically and engaged between the upper and lower members 38 and 40. Member 44 is journaled upon axis member 33 such that gate 14 can swing about the axis member 33. Member 44 is also axially slidable in the vertical direction along axis member 33 such that the gate 14 can be lifted up and set down in a vertical fashion.
Gate frame 36 further includes a pair of inner vertical structural members 46 extending generally vertically and engaged between the upper and lower members 38 and 40. Between the inner vertical structural members 46 is engaged a relatively short member 48 extending generally horizontally. Between the short member 48 and the upper member 36 is engaged two relatively short inner members 50 extending generally vertically. Pivotally engaged within short member 48, lower member 40 and side members 46 is a relatively small gate 52 having four vertically extending structural members and two horizontally extending structural members. Small gate 52 includes a spring biased latch 54 that cooperates with one side member 46 and is biased to the closed position. Small gate 52 is pivotally engaged via pin connectors to members 40, 48 at the end of the gate 52 that is opposite latch 54. Small gate 52 can swing out to either side of gate 14.
Gate frame 36, including structural members 38, 40, 42, 44, 46, 48, and 50 and further including small gate 52 and the structural members of the small gate 52, is preferably tubular. If desired, one or more of such structural members may be rods. Gate frame 36, including such structural members, is preferably formed of a metal. One preferred metal is stainless steel. If desired, aluminum may be used. Gate frame 36 is preferably relatively heavy for a toddler to lift vertically and relatively light for the teenager or adult to lift vertically.
The latch mechanism 16 is shown in
Latch piece 67 is a tube. A rear portion of the latch piece 67 is engaged to one end of a coil spring 72 in member 38. The other end of the coil spring 72 is engaged within member 38, such as to a protruding end of member 46. A front portion 74 of latch piece 74 slides into and out of an inner open end or receiver 76 of member 26 of first side portion 20. When latch piece 67 is in open end or receiver 76, the gate 14 cannot be lifted relative to the frame 12. Nor can the gate 14 be swung relative to the frame 12 because of the nature of an inner tube (latch piece 67) engaged within an outer tube (member 26 of first side portion 20). The coil spring 72 biases the latch piece 67 to the closed position. This closed relationship is shown in
The double stop 18 is shown in
In operation, to open the gate 14, the hand grabs upper member 38 with the thumb positioned on tab 64 of slide 62, as shown in
It should be noted that latch mechanism 16 and double stop 18 are generally aligned vertically. Such provides a two-point connection and minimizes any swaying or tilting of the gate 14 relative to the outer frame 12 such as when a toddler pushes upon the gate 14 when closed.
It should further be noted that, while the double stop 18 holds the gate 14 against a force applied perpendicular to the plane of the gate 14, latch mechanism 16 also holds the gate 14 true against a force applied perpendicular to the plane of the gate. Latch mechanism 16 does this in two ways. First, extension 70, formed in the shape of a half-pipe, includes side sections that confront member 26 of first side portion 20 about side sections of member 26. This provides resistance against such a perpendicular force. Second, latch piece 67 is an inner tube that is received within an outer tube, i.e., member 26. This also provides resistance against such a perpendicular force, as well as providing resistance against a lifting force. In other words, the extension 70 maintains member 40 in a spaced apart and parallel relationship with member 28 to provide a lower limit to vertical travel of gate 14 and further prevents a swinging of the gate 14 when the extension 70 is seated on seat 71, as side sections of the cylindrical extension 70 are seated about side sections of tubular seat 71.
Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalents of the claims are intended to be embraced therein.
