Apparatus having frame separate from gate

Description

FIELD OF THE INVENTION

The present invention relates generally to assembly gates or barriers and more specifically to gates or barriers that are shipped or stored in one form and used in another form.

BACKGROUND OF THE INVENTION

An assembly gate may be referred to a gate that includes two states. A first state may be a state in which the gate is disassembled and shipped and/or stored in the disassembled state. A second state may be a state in which the gate is assembled and in use. Preferably, the first state takes a form that occupies a minimum amount of space. Preferably, a conversion from the first state to the second state or a conversion from the second state to the first state is easy, user friendly and takes a minimal amount of time. Preferably, after conversion from the first state to second state, the form of the second state is as normal as a nonassembly gate and is as structurally sound as a nonassembly gate.

DETAILED DESCRIPTION

As shown in FIGS. 1A and 1B, the base assembly gate or base barrier is indicated in general by the reference numeral 10. Barrier 10 generally includes a first end frame 12, a second end frame 14, and a gate 16 engagable between the end frames 12, 14. Barrier 10 includes a height direction, a length direction defined, for example, by the direction between two door jambs between which the barrier 10 is engaged, and a width or thickness direction. The height, length and width (or thickness) directions extend perpendicular to each other.

First end frame 12 includes a gate confronting standard 18, an upper member 20, a lower member 22, and an end member 24. Standard or upright member 18 confronts the gate 16, is elongate in the height direction, and extends between the upper and lower members 20, 22 with which standard 18 is integral and one-piece. Such an integral and one-piece connection is formed, for example, by welding. Standard 18 is tubular, may be formed of a metal such as steel or aluminum, and is generally rectangular in section. Standard 18 includes an axis extending in the height direction, gate confronting portion 52 of lower member 22 includes an axis extending inwardly from standard 18 in the length direction, and such two axes are oblique relative to each other. In other words, such two axes are slightly greater than ninety degrees, with a range of such two axes being between 90.5 and 100 degrees, more preferably between 90.5 and 95 degrees. An upper end portion 26 and/or an inner end portion 28 of upper member 20 can receive a catch 30 of a latch 32 of the gate 16.

Upper member 20 is elongate in the length direction and extends outwardly from the upper end portion 26 of the standard 18. Upper member 20 is tubular, may be formed of a metal such as steel or aluminum, and is generally square in section. Upper member 20 includes an outer end 34 that includes an opening for slidingly receiving a pressurizing turnable arm 38. Arm 38 includes a threaded shaft 40 that engages such opening in a sliding fashion. Spinnable on the threaded shaft 40 is a hand or finger knob or hand wheel 42 that is threaded and engages the threads of the shaft 40. Fixed to the end of the threaded shaft 40 is a disk 44 for making contact with and bringing pressure to bear upon a location or surface such as a door jamb. In use, the inner end of hand or finger knob 42 makes contact with the end 34 and, as the knob 42 is rotated into the end 34, such rotation draws the threaded shaft 40 in the outward direction and draws the disk 44 outwardly to apply pressure against the door jamb. If desired, disk 44 may be set in a cup or receptacle, having a recess about the size of the disk 44, where such cup or receptacle is screwed to the door jamb. Such cup or receptacle minimizes transverse or up or down movement of the disk 44 relative to the door jamb.

Lower member 22 is elongate in the length direction, runs generally parallel to the upper member 20 when the barrier 10 is assembled, and extends inwardly and outwardly relative to a lower end portion 46 of standard 18. Lower member 22 is tubular, may be formed of a metal such as steel or aluminum, and is generally rectangular in section. The dimensions of the rectangular section of lower member 22 may be identical with the dimensions of the rectangular section of standard 18. In other words, the height and width of the rectangular section of lower member 22 may be identical to the length and width of the rectangular section of standard 18. Lower member 22 includes an outer end portion or end 48 having an opening, where such opening extends inwardly along and spaced from an upper edge of lower member 22 and extends in the length direction. This opening slidingly receives another turnable arm 38. Lower member 22 includes gate confronting inwardly extending portion 52 having an inner end portion 54. Lower member portion 22 and its inner end portion 54 may be or include one of the many connections shown in FIGS. 2A, 2B, 3A, 3B, 4A, 4B, 5A, 5B, 6A, 6B, 7A, 7B, 7C, 8A, 8B, 8C, 9A, 9B, 9C, 10A, 10B, 10C, 11A, 11B, 11C, 13A, 13B, 14A, 14B, 15A, 15B, 18A, 18B 20A, 20C, 21A, 21C, 22, 24, 25, 27, 28A, 28B, 29A, and 29B, and where, after the right and left end frames are slightly modified, the omitted lower connection may be furnished with any one of the lower connections shown in FIGS. 12A, 12B, 12C, 16A, 16B, 17A and 17B.

End member 24 of first end frame 12 includes a tubular post section or upright member section 58 engaged to each of upper member 20 and the outer end portion 48 of lower member 22. Post section 58 is integral and one-piece with upper member 20 and outer end portion 48. Tubular post section 58 is tubular, may be formed of a metal such as steel or aluminum, and is circular in section. Extending outwardly off the tubular post section 58 is a C-shaped upright member 60 having a downwardly and outwardly oblique member portion 62, a medial upright member portion 64, and an upwardly and outwardly oblique member portion 66. C-shaped member 62 is integral and one-piece with post section 58. Member portions 62 and 66 engage post sections 58 at junctions terminating short of the upper member 20 and lower member 22, respectively. C-shaped upright member 60 is a cylindrical member and is preferably formed of a metal such as aluminum or steel. Each of standard 18, post section 58, and member portion 64 includes an axis, and such axes are equidistant from each other. Standard 18 has a greater length than either the length of post section 58 or the length of post 64 (where the length direction is defined as the direction between the two locations between which the barrier 10 is engaged) because, for example, standard 18 along with lower member 22 provides the pressure for engagement between the two locations. First end frame 12 as a whole, including standard 18, upper member 20, lower member 22, post section 58, and C-shaped section 62, are integral and one-piece with each other and are set in a common plane.

Second end frame 14 is identical to first end frame 12 with the following exceptions:

1) A first exception is that second end frame 14 includes, and first end frame 12 does not include, an inwardly extending elongate relatively narrow plate mount 68 for the gate 16. Mount 68 includes a distal end having an opening 69 for a pivot lock pin 70 that engages an opening 72 in gate 16. Mount 68 is preferably formed of a metal such as steel or aluminum. Mount 68 is rigidly affixed, such as by welding, to the upper member 20 of second end frame 14 and extends in the same common plane as second end frame 14. Pin 70 is engaged between the gate 16 and the end frame 14 to which the gate 16 pivots. Pin 70 is on the axis on which the gate 16 pivots. Pin 70 includes a shaft that has an axis coaxial with the axis on which gate 16 pivots. Pin 70 includes a spring biased button 71 slideable into and out of the shaft on an axis perpendicular to the axis of the shaft. Spring biased button 71 is normally biased outwardly. The gate 16, namely member 92, includes a first opening 72 for the shaft and a second opening for the button 71. The second opening is recessed in member 92 and is spaced from first opening 72. The second opening includes two ends, with one of the ends being open to receive button 71 and with the other of the ends being closed to maximize difficulty in depressing the button 71 and thereby maximize difficulty in removing lock pin 70 and disassembling the gated pressurized barrier 10.

2) A second exception is that second end frame 14 includes, and first end frame 12 does not include, an opening 74 extending downwardly from an upper face of lower member 22 of second end frame 14. Opening 74 receives a pin 76 rigidly affixed to gate 16. Opening 69, pin 70, opening 72, opening 74 and pin 76 are coaxial with each other when the barrier 10 is assembled.

3) A third exception is that there is substantially a right angle between the axis of standard 18 and the axis of gate confronting portion 52 of second end frame 14. While an angle of slightly more than ninety degrees can be provided here, such is not required. The angle of slightly more than ninety degrees, as found between the standard 18 and gate confronting portion 52 of the first end frame 12, contributes to the resilient structure for pressurizing the barrier 10 as a whole.

Gate 16 includes a frame 86. Frame 86 is preferably formed of a metal such as steel or aluminum. Frame 86 includes an upper member 88, lower member 90, end member 92 and end member 94. Upper members 88, 90 are engaged to and between the end members 92, 94. Members 88, 90, 92, 94 are tubular and square in section. End member 92 includes the axis on which gate 16 swings. End member 92 depends slightly below and beyond lower member 90 such that lower member 90 and gate 16 as a whole is spaced slightly above the lower members 22 of end frames 12, 14. Pin 76 depends from the lower end of end member 92. Gate 16 rides on the lower end of end member 92. Frame 86 further includes a pair of tubular cylindrical posts 96, 98 engaged to and between upper and lower members 88, 90. Frame 86 further includes a tubular cylindrical member 100 running in the length direction and engaged between posts 96, 98. Frame 86 further includes upright members or tubular cylindrical posts 99, 101 running to and between member 100 and upper member 88. Frame 86 further includes a hinged pet door 102 hingedly engaged between member 100 and member 90 and extending between posts 96 and 98. Pet door 102 includes four spaced apart upright posts extending between an upper horizontal member and a lower horizontal member. Pet door 102 further includes a horizontally slideable spring biased latch 104 engaging post 98. Pet door 102 can swing out of either of the faces of the gate 16. Frame 86 further includes a stop 106 that prevents the gate 16 from swinging through the barrier 10. Instead, gate 16, because of the stop 106, swings only out of one face of the barrier 10. Stop 106 confronts and makes contact with the outer side of gate confronting portion 52 of end frame 12 when the gate 16 is closed.

Gate 16 further includes latch 32. Latch 32 includes a sliding lock 108 that locks down a pivoting lever handle 110 that swings on a pivot 112 engaged to a latch body 114. When the lock 108 is slid back, the handle 110 may be swung up so as to draw the catch 30 in and disengage the catch 30 relative to the upper end portion 26 or upper member 20 such that the gate 16 may be opened.

FIGS. 1A and 1B include a phantom line indicated by reference number 120. Phantom line 120 indicates a break between inner end portions of lower member 22. Lower member 22 includes outer end portion or end 48, gate confronting inwardly extending portion 52, and inner end portion 54. Phantom line 120 generally represents where a lower connection can be made between portions of lower member 22, and such lower connections are shown in FIGS. 2A, 2B, 3A, 3B, 4A, 4B, 5A, 5B, 6A, 6B, 7A, 7B, 7C, 8A, 8B, 8C, 9A, 9B, 9C, 10A, 10B, 10C, 11A, 11B, 11C, 13A, 13B, 14A, 14B, 15A, 15B, 18A, 18B 20A, 20C, 21A, 21C, 22, 24, 25, 27, 28A, 28B, 29A, and 29B. Such lower connections are also shown in FIGS. 12A, 12B, 12C, 16A, 16B, 17A and 17B where right and left end frames are slightly modified.

Mortise joint end 132 includes a pair of tapering sidewalls for confronting sidewalls 140 and a cylindrical hole for confronting cylindrical portion 142. Joint ends 132, 134 are engagable and disengageable to and from each other by sliding the ends 132, 134 vertically relative to each other. Joint ends 132, 134 may be fixed from sliding vertically by a lateral pin 144, shown in FIG. 2B, engaging a lateral hole in each of the joint ends 132, 134. Each of the outer surfaces of the mortise joint end 132 includes a pair of opposing sidewalls 146 and a pair of opposing sidewalls 148 tapering distally and outwardly. When connected, joint ends 132, 134 define an aesthetic joint 130 having opposing intermediate parallel sidewalls 146 between tapering sidewalls 138 and 148 that taper outwardly to the width of intermediate parallel sidewalls 146. The height of joint 130 is the same as the height of member 22 and the height of member portions 124, 126, and 128. Member portions 124, 126, 128 are tubular. Each of end member portions 124, 126 is sealed by an end cap 150. Each of member portions 124, 126 and 128 with their respective joint ends 132, 134 has a length substantially equal to or less than a length of gate 16 so as to minimize the size of the carton or storage box for barrier 10.

FIGS. 3A and 3B show a lower connection 152. Lower connection 152 includes a single joint, with such single joint being joint 130 having mortise joint end 132 and tenon joint end 134, which are also shown in FIGS. 2A and 2B. In FIGS. 3A and 3B there is no intermediate joint 128. Instead lower member 22 includes first end member 154 (that has a greater length than first end member 124 of lower connection 122 of FIGS. 2A and 2B) and second end member 156 (that has a greater length than second end member 126 of lower connection 122 of FIGS. 2A and 2B). Each of member portions 154, 156 with their respective joint end 132, 134 has a length substantially equal to or less than a length of gate 16 so as to minimize the size of the carton or storage box for barrier 10. Each of member portions 154, 156 is tubular and includes end cap 150.

FIGS. 4A and 4B show a lower connection 158. Lower connection 158 includes a single joint, with such single joint being joint 160 having a clamping joint end 162 and clamped joint end 164. Joint end 162 may also be referred to as a mortise joint end 162 when the joint end 162 is closed. Joint end 164 may also be referred to as a tenon joint end 164 when the mortise joint end 162 is closed. Joint ends 162 are engaged to the inner ends of end members 154, 156 using tongue 136 shown in FIG. 2A.

Clamping joint end 162 includes a pair of jaws 166, 168 that pivot relative to each other. Jaws 166, 168 are hingedly secured to a laterally extending base 170 that in turn is secured to an inner end of member 156 by tongue 136. A lever 172 pivotally engaged on one or both sides of base 170 and further pivotally engaged between one or more of jaws 166, 168 may be pivotally actuated to swing the jaws 166, 168 open and closed. Lever 172 and/or jaws 166, 168 and/or the hinged connection to base 170 may utilize an over-center mechanism to swing the jaws 166, 168 open and closed. When the jaws 166, 168 are closed, inner surfaces of the jaws 166, 168 form a keyhole slot for receiving the clamped or tenon joint end 164.

Clamped joint end 164 or tenon joint end 164 forms the shape of a keyhole for mating with clamping joint end 162 when clamping joint end 162 is closed. Clamped or tenon joint end 164 includes a relatively wide block distal head end 174 and a relatively narrow neck end 176. Narrow neck end 176 has the same width as member 22, including member portion 154. Neck end 176 includes tongue 136 for engagement to member portion 154.

If desired, the clamping pressure of jaws 166, 168 can be relatively great, when jaws 166, 168 are closed, so as to prevent vertically sliding of joint ends 162, 164 relative to each other.

If desired, the clamping pressure of jaws 166, 168 can be relatively light, when jaws 166, 168 are closed, so as to permit vertically sliding of joint ends 162, 164 relative to each other. Where the clamping pressure of jaws 166, 168 is relatively light, joint ends 162 and 164 can be engaged and disengaged to and from each other in a vertically sliding manner.

When jaws 166, 168 are open, jaws 166, 168 may be actuated to close by tenon end 164 being pushed into the clamping end 162. The distal face of tenon end 164 pushes against proximal end faces of jaws 166, 168 so as to pivot the distal portions of the jaws 166, 168 closed and, optionally, to pivot the levers 172 to a locked position. In such case where the levers 102 lock, the reverse action of pulling the tenon end 164 in the opposite direction does not draw the jaws 166, 168 open, however, until the levers 172 are pivoted to release the over-center mechanism or draw the over-center mechanism over center. Member portions 284, 286 are tubular.

FIGS. 5A and 5B show a lower connection 178. Lower connection 178 includes a single joint, with such single joint being joint 180 having a female joint end 182 and male joint end 184.

Frame 462 further includes a stop 106 that prevents the gate 16 from swinging through the barrier 452. Instead, gate 16, because of the stop 106, swings only out of one face of the barrier 452. Stop 106 confronts and makes contact with the outer side of gate confronting portion 52 of end frame 12 when the gate 16 is closed.

U.S. Pat. No. 7,975,431 B2 issued Jul. 12, 2011 and entitled Multiple Piece Gated Pressurized Barrier is hereby incorporated by reference in its entirety herein.

As shown in FIGS. 20C, 21C, 24 and 27, a base assembly gate or base barrier is indicated in general by the reference numeral 500. Barrier 500 generally includes a first end frame portion 512, a second end frame portion 514, and a gate 516 engagable between the end frames portions 512, 514. First and second end frame portions 512 and 514 make up a single frame unit 515. Disassembly of the single frame unit 515 destroys the integrity of the unit. First end frame portion 512 includes a gate confronting standard 518, an upper member 520, a lower member 522, and an end member 524. Second end frame portion 514 includes a gate confronting standard 526, an upper member 528, a lower member 530, and an end member 532. As to barrier 500, first and second end frame portions 512, 514, gate 516, standard 518, upper member 520, end member 524, standard 526, upper member 528, end member 532, and latch 534, barrier 10 shown in FIGS. 1A and 1B is hereby incorporated by reference.

FIGS. 20C, 21C, 24 and 27 show the two-unit barrier 500 in an assembled form. The two-unit barrier 500 includes the first end frame portion 512, the second end frame portion 514 and the gate unit 516. The first end frame portion 512 includes the first lower member portion 522. The second end frame portion includes the second lower member portion 530.

The gate unit 516 is swingably engaged to one of the first and second end frame portions 512, 514. The gate unit includes a latch 534 that is latchable to the other of the first and second end frame portions 512, 514.

The first and second end frame portions 512, 514 are engaged to each other such that the first and second end frame portions 512, 514 are a single unit. The first and second end frame portions 512, 514 are expandable and retractable relative to each other. The first and second end frame portions 512, 514 are retractable toward each other such that the first and second end frame portions 512, 514 confront each other in a retracted position where the gate unit 516 is not engagable between the first and second end frame portions 512, 514. In the retracted position, the horizontal distance between gate standards 518, 526 is less than the width of the gate or gate unit 16. The first and second end frame portions 512, 514 are fixable at an expanded position where the gate unit 516 is engagable to and between the first and second end frame portions 512, 514 such that the two-unit barrier 500 is assembled.

When the two-unit barrier 500 is assembled, the gate unit 516 confronts each of a) the first end frame portion 512, b) the second end frame portions 514, c) the first lower member portion 522 of the first end frame portion 512, and d) the second lower member portion 530 of the second end frame portion 514.

The lower member portions 522, 530 of the first and second end frame portions 512, 514 are engaged to each other such that disengagement of the first and second end frame portions 512, 514 from each other destroys an integrity of an engagement between the first and second end frame portions 512, 514, namely, the engagement between the lower member portions 522, 530 of the first and second end frame portions 512, 514. To provide for such a feature, the distal end of the male lower member portion 522 may include an outwardly extending lip 544 extending outwardly from one or more of the four outer faces of the male lower member portion 522. This outwardly extending lip 544 may hit or engage an inwardly extending lip 546 of the female lower member portion 530, which lip 546 may extend inwardly from one or more of the four inner side faces of the female lower member portion 530. In the expanded position, lips 544, 546 hit or engage each other. In the retracted position, lip 546 of the female lower member portion 530 is adjacent to or confronts standard 518 of the first end frame portion 512 and lip 544 of the male lower member portion 522 is adjacent to or confronts the standard 526 of the second end frame portion 514. To separate first end frame portion 512 from second end frame portion 514 such that the end frame portions 512, 514 are separate pieces, the lips 544, 546 would be destroyed or separated from their respective lower member portions 522, 530.

The lower member portions 522, 530 are engaged to each other with a telescoping arrangement. The first lower member portion 522 includes a first dimension and the second lower member portion 530 includes a second dimension. The first dimension is slightly less or equal to the second dimension where the dimension may be a diameter, width, or height such that the first lower member portion fits inside of the second lower member portion. The first lower member portion 522 may include a first width and the second lower member portion 530 may include a second width, where the first width is less than the second width such that the first lower member portion 522 slides inside of the second lower member portion 530. The first lower member portion 522 may be a male member and the second lower member portion 530 may be a female member.

The single unit telescoping frame 515 shown in FIGS. 20A, 21A, 22 and 25 defines a plane in each of the expanded and retracted positions. The gate unit 516 in FIGS. 20B, 21B, 23 and 26 defines a plane. The two-unit barrier 500 shown in FIGS. 20C, 21C, 24, and 27 defines a plane when the gate unit 516 is closed.

The telescoping arrangement between lower member portions 522 and 530 may include a set of four snaps or pins or snap pins or spring biased buttons 536, 537. Button 536 is shown in FIGS. 24, 27, 28A and 28B. Button 537 is shown in FIG. 22.

Two buttons 536 are engaged on one side face of lower member portion 522 and two buttons 537 are engaged on the other side face of lower member portion 522. Buttons 536 and 537 oppose each other such that there is a first button 536 opposing a first button 537 and such that there is a second button 536 opposing a second button 537. One set of opposing buttons 536, 537 is disposed on a distal end of lower member portion 522. The other set of opposing buttons 536, 537 is disposed on an intermediate portion of male lower member portion 522.

Buttons 536, 537 cooperate with a pair of openings 538, 539 formed in female lower member portion 530. One opening 538 is formed in one side face of lower member portion 530 and the other opening 539 is formed in the other side face of lower member portion 530. Openings 538, 539 oppose each other. Openings 538, 539 are formed in a distal end of lower member portion 530.

FIGS. 29A and 29B show an alternate embodiment to a fixing of the lower member portions 522, 530 relative to each other. In this embodiment, a bolt or pin 540 may engage a threaded or nonthreaded opening 542 in the distal end of female lower member portion 530. The bolt or pin 540 may then further engage a threaded or nonthreaded opening formed in the distal end of the male lower member portion 522. Or the distal end of the bolt or pin 540 may engage or bring pressure to bear on a side face portion of male lower member portion 522 to fix the lower member portions 522, 530 relative to each other.

If desired, the first embodiment shown in FIGS. 28A and 28B and the second embodiment shown in FIGS. 29A and 29B may have a number of positions where the distal ends of the lower member portions 522, 530 are fixed to each other. Such plurality of positions, for gate units 516 of different sizes, where the end frame portions 512, 514 are fixed at different distances from each other, may be accomplished by providing for a number of openings 538 in the case of the first embodiment or may be accomplished by providing for a number of openings 542 on either or both of the distal ends of lower member portions 522, 530 in the case of the second embodiment. Also, it should be noted that the second embodiment may set the first and second lower member portions 522 and 530 at an infinite number of positions where the distal end of the pin 540 brings pressure upon the side face of the male lower member portion 522.

The male and female lower member portions 522, 530 overlap a sufficient length in the expanded position to provide lateral stability between the end frame portions 512, 514.

If desired, the inner vertical edge of standard 518 of end frame portion 512 may serve as a stop in the retracted position for the distal end of female lower member portion 530 of end frame portion 514 whereupon the intermediate buttons 536, 537 may be eliminated.

When buttons 536 and 537 are employed, barrier 500 is fixed in each of the retracted position (such as during shipping) and the expanded position (such as during use).

Gate unit 516 is fixed in frame unit 515 when the frame unit 515 is in the expanded position. The swinging end of gate unit 516 may engage upper member portion 520 and lower member portion 522 of first end frame portion 512 through an upper pin arrangement and a lower pin arrangement. The latching end of gate unit 516 may engage a) one or more of standard 526 and upper member portion 528 with latch 534 and b) lower member portion 530 with a stop 548.
