The gate assembly is movable between open and closed positions with respect to the doorway. It will be appreciated the opening could be any suitable doorway, opening, stairway and/or the like. Different features of the gate assembly will now be described below. It will be appreciated by persons skilled in the art that any or any combination of features can be provided on the gate assembly of the present invention.
Extendible Gate Assembly
In accordance with a first aspect of the present invention, gate assembly 2 is extendible to allow the width of the gate to be adjusted for fitting the same into different sized openings, as shown in FIGS. 1-3, 9 a-10 c.
The extendible gate includes two gate panels 8, 10, end parts of which are provided in overlapping engagement with each other in use. The gate panels 8, 10 have movement means to allow the gate panels to be slidably moved relative to each other for adjusting the overall width of the gate panels. Thus, the gate panels can be moved between retracted and extended positions with respect to an opening.
Each gate panel 8, 10 includes a top panel member 12, 12′, a bottom panel member 14, 14′ and a plurality of upright struts 16, 16′ provided at spaced distances apart between the top and bottom panel members.
An inner surface of each of top panel members 12, 12′ and bottom panel members 14, 14′ is provided with an elongated channel 18, 18′ substantially parallel with the longitudinal axis of said top member. Location means in the form of a plurality of shaped recesses 20′ are provided at spaced distances apart on the opposite surface 22′ from the opening 24′ of the channel. These shaped recesses 20′ act as pre-determined width positions for the two gate panels relative to each other. More particularly, each recess 20′ includes a rear wall 26 and side walls 28 provided at an acute angle relative to said rear wall, thereby providing each recess with front and rear ramps.
The overlapping ends 30′, 30 of each gate panel 8, 10 respectively has an engaging arm 32 which protrudes through opening 24′ of channel 18′ of the opposite gate panel and is slidably mounted therein. Thus, engaging arm 32 is movable relative to the longitudinal axis of top panel member 12′. Engagement of arm 32 in channel 18′ is such that the gate panels cannot be easily separated once assembled.
A protruding member in the form of a bolt 34 is movable relative to an aperture 36 defined in arm 32 between a protruding position, as shown in FIGS. 10 a and 10 b, and a recessed position, as shown in FIG. 10 c. A spring 38 is joined to the rear 40 of bolt 34 to resiliently bias bolt 34 to the protruding position. Thus, bolt 34 is movable substantially perpendicularly to the longitudinal axis of channel 18′ and engaging arm 32.
The free end 40 of bolt 34 is provided with angled side edges 42 which are substantially complementary to side walls 28 of the recesses 20′, thereby allowing the bolt to be slid into and out of the recesses 20′ on relative sliding movement of the gate panels as will be described in more detail below.
Locking means in the form of a movable locking arm 44 is slidably mounted relative to an opening 46 defined in end 30 of the gate panel 10 between a locked position, wherein a recess 48 defined at an inner end of arm 44 engages with rear 40 of bolt 34, as shown in FIG. 10 a, and an unlocked position, wherein recess 48 is moved a spaced distance apart from rear 40 of bolt 34, as shown in FIGS. 10 b and 10 c. Thus, locking arm 44 is moved substantially parallel to the longitudinal axis of top panel member 10. A user actuation portion 50 is provided at free end of arm 44 and forms part of the shaped end of the gate panel when in the locked position. Portion 50 allows a user to move locking arm 44 between the locked and unlocked positions. Thus, in the locked position, portion 50 abuts against end 30 of gate panel 10 and locking arm 44 is recessed within end 30 of gate panel 10. In the unlocked position, portion 50 is a spaced distance apart from end 30 of gate panel and part of locking arm 44 protrudes from end 30 of gate panel 10.
The end of locking arm 44 engaging with the rear of bolt 34 is provided with a narrowing tapered or curved end which engages with a narrowing tapered or curved end of bolt 34 to provide relatively smooth reciprocal movement of the arm 44 relative to bolt 34.
In operation of the movement means, when a user wishes to adjust the width of the gate assembly, the user slides out user actuation portion 50 from end 30 to an unlocked position, thereby removing locking arm 44 from engagement with the rear 40 of bolt 34. The user then grips the top panel members 8, 10 and slides the engaging ends of the members away from each other, thereby reducing the width of the gate, or slides the engaging ends of the members towards each other, thereby increasing the width of the gate.
On relative movement of the gate panels 8, 10, bolt 34 is slidably moved out of a recess 20′ (i.e. in a direction substantially parallel to the longitudinal axis of the top member), this movement aided by the angled ends 42 of bolt 34 sliding up a ramp in recess 20′ defined by side walls 28. When bolt 34 contacts surface 22′, the resilience of spring 38 causes bolt 34 to slidably move relative to aperture 36 to a recessed position, thereby allowing engaging arm 32 to freely slide in channel 18. When bolt 34 passes an adjacent recess 20′, bolt 34 is resiliently biased into the recess and the user hears a clicking sound, thereby informing the user that one of the pre-determined width settings has been reached. The user can continue to slide the gate panels to find a further recess 20′ or can lock the bolt 34 in the already reached recess 20′. In order to lock the gate panels in the required setting, the user pushes portion 50 into engagement with end 30 of gate panel 10, thereby bringing locking arm 44 into engagement with the rear 40 of bolt 34.
The housing assembly end 30 is typically engaged to top panel member 12 by a bolt 52.
Each gate panel typically has movement means of the type described above, so that an engaging arm 32, 32′ on each gate panel 10, 8 is slidably mounted in the channel 18, 18′ of the other gate panel 10, 8. The same reference numerals are used to designate the same components with a ′ used to designate components on gate panel 8. Similar movement means can also be provided on both the top and bottom panel members 12, 12′ and 14, 14′ respectively.
Both the top and bottom panel members of each gate panel can have movement means of the type described above. Locking means are preferably provided on the top panel member only but could be provide on the bottom panel member if required.
In accordance with a second aspect of the present invention there is provided hinge means 102 for a gate assembly, as shown in FIGS. 1-4. The hinge means can be used on any gate assembly and not just an extendible gate assembly as in the figures.
Hinge means 102 includes a first hinge part 104 joined to an end strut 16 of gate panel 10 and a second hinge part 106 joined to an upright spacing element 108. Upright spacing element 108 is joined to a wall extrusion member 110 for attachment to a wall surface 6 defining opening 4. Each hinge part 104, 106 is substantially elongate in form and the longitudinal axis of said hinge parts is substantially parallel to strut 16.
Each hinge part 104, 106 include a plurality of protruding fingers 112, 114 protruding substantially perpendicularly to the longitudinal axis of said hinge part. The protruding fingers 112, 114 are provided a spaced distance apart with recesses 116, 118 defined therebetween. When assembled, the protruding fingers on one of the hinge parts are located in the recesses of the other hinge part, thereby forming a plurality of inter-engaging or stacked fingers. Engagement means in the form of an elongate hinge pin (not shown) is provided through the ends 120 of the protruding fingers and substantially parallel to the longitudinal axis of the hinge parts to keep the hinge parts engaged together. The hinge pin allows pivotable movement of the fingers 112, 114 relative to each other to allow the gate panel 10 to be moved between open and closed positions with respect to the doorway opening 4. The ends 120 of the fingers 112, 114 are also curved in shape to allow anything that might be trapped in a recess 114, 116 to be forced out on movement of the hinge parts relative to each other.
In accordance with a third aspect of the present invention and with reference to FIGS. 5-6 c, there is illustrated alternative hinge means 202 for use on a gate assembly according to the present invention.
The hinge means 202 includes a resilient elongate rubber hinge member 204 which is substantially flexible, at least in a central portion 206 thereof. Hinge member 204 has a first end 208 which is of substantially complementary shape to a recess 210 defined along the end 211 of gate panel 10, and a second end 212 which is of substantially complementary shape to a recess 214 defined along an end of spacing element 108. The inherent flexibility and resilience of hinge member 204 allows gate panel 10 to be pivoted between open and closed positions about central portion 206.
According to a fourth aspect of the present invention, there is provided indicator means for use on a gate assembly to allow a user to visually determine when the gate assembly is correctly fitted in an opening.
With reference to FIGS. 7 and 8, there is illustrated engagement means in the form of a friction pad 216 provided at an end 218 of an adjustment arm 220. An opposite end 222 of adjustment arm 220 is movably located in a channel defined in housing 224. The housing 224 is joined to a frame 226 to which a gate assembly 2 is movable relative thereto.
A threaded bolt 228 is joined to end 222 and passes through housing 224 and frame 226, the head 230 of bolt 228 being substantially flush or recessed with end 232 of frame 226. An Allen key 234 or screw driver head 236 can be located in a suitable shaped aperture in head 230 to allow rotation of bolt 228 when the gate is open. This rotation moves bolt 228 and thus arm 220 and friction pad 216 between extended and retracted positions to allow secure engagement of friction pad 216 with a wall surface defining an opening in which the gate assembly is located.
Ruler markings 238 are provided on adjustment arm 220 to allow a user to move the adjustment arm to a pre-determined setting and/or to compare the setting to other adjustment arms provided on the gate.
For example, adjustment arms can be provided adjacent each corner of the gate assembly to engage with a wall surface and the indicator means can allow a user to determine whether the engaging force at each corner of the gate is substantially the same. It is not essential for the visual indicator means to be provided and FIG. 8 illustrates a similar adjustment mechanism to the one shown in FIG. 7 on a lower part of the gate assembly but the indicator markings are not provided.
According to a further aspect of the present invention, the gate assembly in one embodiment is provided in a modular construction. The components of the gate assembly can be detachably attached to allow erection and dismantling of the gate assembly by a user at the site of use or by a manufacturer.
Referring to FIG. 16, the upright struts 16, 16′ of each gate panel 8, 10 are detachably attached to protrusions 302, 302′ defined at spaced intervals on the top and base surfaces of the bottom sub panel member 314, 314′ and top sub panel member 312, 312′ respectively. The protrusions are located in open ends of the struts 16, 16′. Screws 304, 304′ can be located through the top and bottom sub panel members to securely engage the struts thereto.
The bottom and top sub panel members 314, 314′, 312, 312′ are then slidably engaged with bottom and top panel members 14, 14′, 12, 12′ respectively, as shown in FIG. 17 a. More particularly, bottom and top panel members 14, 14′, 12, 12′ are engaged together by the movement mechanism described above and bottom and top sub panel members of gate panels 8, 10 are slid inwardly towards each other, as shown by arrows 316, 318. The end struts 320 of each gate panel 8, 10 which are closest to the wall surface when fitted have corner components 322 detachably attached to the end of each panel member and to the opening of the strut 320. The corner components 322 are ‘L’ shaped having a body part 324 and two protruding parts 326, 328 provided substantially perpendicular to each other on adjacent sides of said body part 324.
A frame can be provided around the gate panels to which at least part of the gate panel can be mounted to in use. In FIG. 1, a frame 330 is defined on the left hand side of the gate assembly and houses a latching mechanism. The frame 330 is joined to wall surface 6 and is provided only partially down the side of the gate assembly. In FIG. 18, the frame 330 is provided around substantially the entire gate assembly (i.e. on the base and two sides).
FIGS. 11 and 13 illustrate engagement of frame 330 to a wall via a wall extrusion member 332 in one embodiment. This attachment is on the left side or latching side of the gate assembly in this example. Wall extrusion member 332 has a substantially centrally located body portion 334 with a channel 336 defined longitudinally thereof. Body portion 334 is secured to a wall surface via a screw 338. Channel 336 has overhanging lips 338 adjacent an opening of said channel for receiving a complementary shaped end of an adjuster housing 340 of frame 330. Housing 340 is slidably received in channel 336. Flanges 342 are provided either side of body portion 334 and are angled from lips 338 to the wall surface to provide a neat aesthetic finish. An adjustment screw 344 is rotatably mounted in housing 340 to allow fine adjustment of the position of the frame 330 relative to wall extrusion member 332. Frame 330 is joined to an end 346 of screw 344.
On the right side or hinge side of the gate assembly a similar wall extrusion member 110 to member 332 is provided, as shown in FIGS. 12 a-13. However, in this embodiment, a spacing element 108 is slidably inserted in channel 336 in place of adjuster housing 340 in FIG. 12 b. Spacing element 108 has a T shaped end 348 slidably mounted in channel 336 and, at an opposite end, has a channel 350 similar in shape to channel 336. A part of hinge 102 has a T-shaped end 352 for slidable location in channel 350 in FIG. 12 b. In FIG. 12 a, an additional spacing element 108 is located in channel 350, thereby further increasing the distance of the hinge from the wall 6. In FIG. 12 c, the hinge 102 is joined directly to channel 336.
A latching mechanism 402 is provided along one side of the gate assembly and an embodiment is illustrated in FIGS. 15 a-15 d. Mechanism 402 includes a handle portion 404 provided on a lower surface of top panel member 12′. An elongate arm 406 extends downwardly from said handle portion 404 and two latch portions 408 are provided at spaced intervals on the length thereof and protrude outwardly of said arm 406. The elongate arm 406 is joined to an extrusion 410 which is housed in end strut 320. The latch portions 408 are movably located in latch housings 410 provided on frame 330. Thus, as handle 404 is moved in an upwardly direction towards top panel member 12′, latch portions 408 are moved upwardly and inwardly of end strut 320, thereby releasing portions 408 from engagement in the latch housings 410 and allowing the gate panel to be moved to an open position.
FIG. 14 shows a more detailed view of latch mechanism 402. Each latch portion 408 is pivotably mounted to a part 420 of arm 406 via a pivot screw 412 and is resiliently biased to a latched position via a spring 414. Latch portion 408 includes a main body 416 with a latching protrusion 418 at an end thereof. Movement of handle 404 in an upwardly direction causes part 420 to move upwardly relative to arm 406, thereby causing an end of latch body 416 of latch portion 408 to engage with an angled surface 422 of arm 406. Further movement of body 416 against surface 422 causes body 416 to pivot, thereby moving latching protrusion 418 inwardly of arm 406.
