QUICK RELEASE SOFT GATE

Background Of The Invention
The present invention relates to a closure device for placement in a doorway and, more particularly, to a security gate which may be frictionally engaged with a doorway for preventing infants or small children from passing through the doorway, and which may be easily and quickly released from the doorway.
In environments where small children or infants are present, it is generally desirable to have a closure device or security gate which may be removably placed within an area way, such as a doorway, to prevent passage therethrough. For example, it may be desirable to restrict small children to a particular room without shutting the door to the room such that one can look into the room or the children can see an adult nearby.
Various means and techniques have been devised for the formation of barriers or closures across area ways wherein the gate may be removably mounted within the area way and which typically include means for adjusting the width ofthe gate to accommodate different distances between the side portions ofthe area way. For example, U.S. Patent No. 4,492.262 to Gebhardt discloses an infant security door gate assembly which includes upper and lower support bars incorporating coil springs positioned within
telescoping tubes to form a compression friction fit within the doorway. In addition, the gate of Gebhardt is formed of a pair of complementary
overlapping panels.
U.S. Patent No. 4,944, 117 to Gebhardt et al. and U.S. Patent No.

5,272,840 to Knoedler et al. disclose security gate constructions which include overlapping substantially rigid panels which may be adjusted relative to each other to provide for a width adjustment.

While the above-described gates are satisfactory for preventing passage of an infant or small child through a doorway, there is a need for a security gate which is adapted to be easily mounted within a doorway, and which is additionally capable of being quickly released from the doorway.

Summary Of The Invention
In accordance with the present invention, a security gate is provided which forms a releasable closure adapted for disposition between spaced, confronting sides of an area way, such as a doorway, and which may be easily removed from the doorway and conveniently folded to a compact form.
In one aspect, the present invention provides a releasable closure for disposition between spaced confronting sides of an area way and including first and second horizontal members for extending between the sides ofthe area way. A pair of vertical members are provided extending between the horizontal members such that the horizontal and vertical members define a frame for the closure. A panel is supported within the frame defined by the horizontal and vertical members, and the panel is preferably formed of a flaccid material, such as a fabric.
First and second lock assemblies are attached to first ends ofthe first and second horizontal members, respectively. Each ofthe lock assemblies includes a body portion mounted to a respective first end, and a thrust member pivotally connected to the body portion. The thrust member is connected to the body portion by means of first and second link members which are pivotally mounted to the body portion and to the thrust member. The link members are substantially parallel to each other and define a parallelogram structure in combination with the body portion and thrust member. Movement ofthe thrust member toward the body portion causes the thrust member to move in a horizontal direction away from the first end.
Thus, the closure ofthe present invention may be mounted in an area way by engaging second ends ofthe horizontal members, opposite from the first ends, with one side ofthe doorway and engaging an end ofthe thrust members with the opposing side ofthe area way. Pushing down on the first ends ofthe horizontal members causes the link members to move to an over center position within the body portion ofthe lock assembly while also moving the thrust members outwardly to thereby form a positive friction fit within the area way.
In addition, the horizontal members comprise telescoping tubes which are spring biased away from each other. The springs within the horizontal members provide a biasing force to ensure that the horizontal members are firmly held in place within the area way.
The vertical members include tube rings located at each end thereof for engaging the horizontal members. The tube rings may be detached from the horizontal members to permit the gate to be folded for storage or transport.
Therefore, it is an object ofthe present invention to provide a security gate which may be firmly mounted within an area way, and which may be easily released for removal from the area way.
It is a further object ofthe invention to provide a security gate which may be partially disassembled and folded when not in use.
Other objects and advantages ofthe invention will be apparent from the following description, the accompanying drawings and the appended claims.

Detailed Description Of The Preferred Embodiment
Referring to Fig. 1, the security gate 10 of the present invention is shown extending across an area way, such as a doorway, including spaced, confronting sides 12, 14. The security gate 10 includes a central panel portion 16 formed of a flexible flaccid material, such as a fabric, supported by a frame defined by first and second horizontal members 18, 20 and first and second vertical members 22, 24. The first horizontal member 18 forms an upper support and includes a first end 26 and a second end 28. Similarly, the second horizontal member 20 defines a lower support member having a first end 30 and a second end 32. The vertical member 22 is connected to the horizontal members 18, 20 at the first ends 26, 30, and the second vertical member 24 is connected to the horizontal members 18, 20 at the second ends 28, 32. It should be noted that upper and lower portions 34, 36 ofthe panel 16 define tubular material portions through which the horizontal members 18, 20 pass, and the side portions 38, 40 ofthe panel 16 similarly define tubular material portions for receiving the vertical members 22, 24 therethrough.
Referring to Fig. 2, the first or upper horizontal member 18 is shown, it being understood that the second horizontal member 20 is provided with an identical construction. The horizontal member 18 is formed of a pair of tubes 42, 44 located in telescoping relationship to each other and biased outwardly from each other by a compression spring 46 in a conventional manner known in the art. A lock assembly 48 is attached to the first end 26 of the horizontal member 18, and an end cap 50 is attached to the second end 28. The lock assembly 48 includes a body portion 52 having a shoulder 54 defining a shoulder area 56. Similarly, the end cap 50 includes a flange defining a shoulder 58 adjacent to a shoulder area 60.
Referring further to Fig. 1, the first vertical member 22 includes identical tube rings 62 at opposing ends thereof wherein one ofthe tube rings 62 is located in the shoulder area 56 ofthe lock assembly 52, and the other tube ring 62 is engaged with a similar shoulder area on a lower lock assembly 64 of the horizontal member 20. The second vertical member 24 also includes tube rings 66 at opposing ends thereof wherein one ofthe tube rings 66 engages the shoulder area 60 ofthe end cap 50, and the other tube ring 66 engages a similar shoulder area on the lower end cap 68.
Referring to Figs. 3 - 5, the lock assembly 48 is illustrated wherein the body portion 52 includes a substantially U-shaped forward portion 70 and a tubular mounting portion 72 for attachment to the second end 26 of the respective horizontal member 18. First and second pivot links 74, 76 are pivotally mounted within the forward portion 70 by respective pivot pins 78, 80.
A thrust body 82 is formed as a U-shaped member connected to the body portion 48 by the link members 74, 76 at pivot pins 83, 84. The link members 74, 76 extend substantially parallel to each other such that the link members 74, 76, body portion 52 and thrust member 82 define a parallelogram structure for guiding movement ofthe thrust member 82 relative to the body portion 52. Thus, as the thrust member 82 moves from a position displaced downwardly from the body portion 52, as illustrated in Fig. 3, to the position shown in Fig. 4 wherein the thrust member 82 is positioned upwardly into close association with the body portion 52, it moves in a direction away from the first end 26 ofthe horizontal member 18. In this manner, the thrust member 82 moves into pressing engagement with the side ofthe area way 12 as, for example, the first end 26 is pressed downwardly with a contact pad 88 ofthe thrust member 82 in engagement with the side 12.
It should be noted that as the relative position between the thrust member 82 and body portion 52 moves from that shown in Fig. 3 to the position shown in Fig. 4, the link members 74, 76 are moved to an over center position such that the thrust member 82 will tend to remain in the locked position shown in Fig. 4. Further, the spring 46 within the horizontal member 18 provides a resilient biasing force for maintaining the lock assembly 48 in a locked position.
It may also be noted that the first link 74 is located above the second link 76, and the pivot 80 for the second link 76 is located closer to the first end 26 then the pivot 78 for the first link 74. This construction provides for a stable linkage when the lock assembly 48 is in a locked position.
Further, side walls 90 ofthe thrust member 82 are provided with curved slots 92 which are adapted to receive the first link member pivot pin 78 therein as the thrust member 82 moves to a locked position and which may define a stop position upon engagement of an end wall ofthe slot 92 with the pin 78.
Further, a torsion spring 94 may be provided engaged with one of he links 76 for providing a biasing force to move the thrust member 82 to a downward location when it is not positioned for locking the gate 10 in an area way.
Referring further to Fig. 6, the tubular portion 72 ofthe body portion 52 includes a latching tongue 96 which is positioned to latch and maintain the tube ring 62 in position on the shoulder area 56. The end caps 50, 68 include a similar tongue 98 for latching the tube rings 66 in position. It should be noted that the locking assemblies 48, 64 and end caps 50, 68 are preferably formed of a plastic material and that the latching tongues 96 and 98 are preferably formed integrally with the locking assemblies 48, 64 and end caps 50. 68, respectively. Further, the tube rings 62. 66 and respective latching tongues 96, 98 operate in a manner similar to that disclosed for the latching mechanism ofthe gate disclosed in U.S. Patent Application Serial No. 08/276,948, assigned to the assignee ofthe present invention, and incorporated herein by reference.
In use, the present gate 10 may be assembled for use and disassembled for transportation or storage. Specifically, the horizontal members 18, 20, in a disassembled configuration, are removed from
association with the tube rings 62, 66 and are separated from the upper portion 34 and lower portion 36 of the panel 16. Thus, the vertical members 22, 24 maybe brought together and the panel 16 folded to form a compact
configuration for the gate 10.
In assembling the gate 10, it should be noted that the tube rings 62 include a circular portion which defines an inner circumference larger than an inner circumference defined by a circular portion ofthe tube rings 66. The circumference ofthe tube rings 62 is such that the end caps 50, 68 may be passed through the tube rings 62, through the upper and lower portions 34, 36 and through the tube rings 66 until the shoulders 58 engage with the tube rings 66. As the horizontal members 18, 20 are passed through the upper and lower portions 34, 36, the shoulder area 56 is brought into engagement with the tube rings 62, and the tube rings 62 are of such a circumference that they will engage the shoulders 54 ofthe respective locking assemblies 48, 64 and be maintained in position by the latching tongues 96. Disassembly ofthe gate 10 may be accomplished by reversing the assembly procedure including depressing the latching tongues 96, 98 to release the tube rings 62, 66 from engagement with the ends ofthe horizontal members 18, 20.
In positioning the gate 10 within an area way, the horizontal members 18, 20 are initially adjusted by rotating the tubes 42, 44 relative to each other to thereby adjust the overall length ofthe horizontal members 18, 20 in a conventional manner known in the art whereby the contact pads 88 of the locking assemblies 48, 64 define an engagement portion which is brought into engagement with the side wall 12, and contact pads 100 on the end caps 50, 68 are brought into engagement with the wall 14. The first ends 26, 30 of the horizontal members 18, 20 are then pushed downwardly causing relative movement between the thrust members 82 and body portions 52 ofthe lock assemblies 48, 64 whereby the thrust members 82 move upwardly into the body portions 52 while moving horizontally away from the first ends 26, 30 of the horizontal members 18, 20. During this movement, the springs 46 within the horizontal members 18, 20 compress to provide a firm engagement force for maintaining the link members 74, 76 in their over center locked position to thereby maintain the gate in position between the sides 12, 14.
When it is desired to release the gate, the first ends 26, 30 of the horizontal members 18, 20 are lifted to quickly release the horizontal members 18, 20 from engagement with the sides 12, 14 of the area way. In this manner, an easily positioned gate is provided which may be quickly released from a doorway and which also provides for a compact configuration when it is desired to store or transport the gate.

While the form of apparatus herein described constitutes a preferred embodiment of this invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope ofthe invention which is defined in the appended claims.
