Definitions

• the present invention relates to a gate post.
• gate posts In the field of outdoor closure systems there are generally two kinds of gate posts, namely a support gate post on which the closure member is attached and a free gate post against which the closure member closes.
• the gate posts In view of their different functions, the gate posts are usually different in size, shape, material, rigidity, etc.
• hinges may be front mounted, rear mounted, or side mounted.
• Gate closers may act on the closure member or on the hinge. Due to the various configurations and in order to ensure the required strength, there is usually only limited space for optional components on the support gate post as addressed in EP 1 482 120 .
• Such functional components include access control means (e.g. keypad, videophone, etc.), postal receiving means (e.g. letter box or packet box), identification information (e.g. resident name, house number, etc.), lighting, etc.

• Examples of such modular gate posts are disclosed in JP 2001/262962 ; JP 2005/171660 ; JP 2006/241877 ; JP 2008/280755 ; and JP 2009/094370 .
• a main issue with these kinds of gate posts is that they are not able to support a closure member.
• the entire gate post may be to be revised as there is limited modularity.
• the present invention is generally based on the provision of a gate post having a dedicated bearing frame configured to support a gate.
• the inventors realized that such a bearing frame enables a single gate post design to be used both as a supporting gate post and a free gate post. This firstly provides gate posts that are similar in size, shape, material, etc. This secondly allows to reduce stock as a single bearing frame may be used for both kinds of gate posts.
• the aspects of the present invention are further based on providing convenient ways by which to mount various functional and/or structural components onto the bearing frame depending on user needs.
• a gate post extending in an upright direction and comprising a bearing frame configured for supporting a gate, the bearing frame comprising: a gate facing side wall and an opposite side wall which are mutually parallel and extend in a depth direction between a front edge and a back edge, the depth direction being perpendicular to the upright direction; and a front wall and a back wall which are mutually parallel and extend in a width direction between a gate facing edge and an opposite edge, the width direction being perpendicular to both the upright direction and the depth direction, wherein at least one of the front wall and the back wall comprises a substantially planar area provided with a plurality of cut-outs configured to receive a functional component, wherein a diagonal buttress is provided in each cut-out, the diagonal buttresses being integrally formed with the remainder of the respective wall (i.e. the wall in which the cut-out is formed).
• the first aspect is based on providing preformed cut-outs in the front and/or back wall of the bearing frame. These cut-outs provide dedicated areas in which a functional component can be partially received thus allowing the functional components to extend into the bearing frame. In other words, the outer dimensions of the bearing frame can be maximised (thus improving rigidity and strength) without having to take account of the various functional components that may have to be added.
• the gate post has to create (e.g. by sawing, milling, or the like) an individual and unique cut-out pattern in each bearing frame depending on the user-selected functional components.
• the provision of the integrally formed diagonal buttress reduces the negative impact of the cut-outs on the strength and rigidity of the bearing frame.
• the provision of the cut-outs naturally causes a reduction in strength and rigidity of the bearing frame. This reduction is decreased as each cut-out has an integrally formed diagonal buttress, which are known as an effective means for transferring forces and preventing buckling.
• the buttresses are also designed to be removed only when the cut-out in question is to be used for a functional component thus minimizing the rigidity reduction to only cut-outs where a functional component is indeed present.

• the upstanding sidewalls and/or the backwall sections can be used as anchor points for functional components without having to damage (e.g. by threaded fastening members, welds, etc.) the front (i.e. visible) side of the front cover.
• the C-shape profile and the recess in the front wall are also further convenient to mount the cover to the bearing frame with fastening means that are not visible from the outside of the gate post. This is due to the upstanding sidewalls and/or the backwall sections of the cover profile being overlapping with wall sections of the bearing frame.

• some of these edges coincide with one another, namely: the front edge 18a and the gate facing edge 21a; the front edge 19a and the opposite edge 21b; the rear edge 18b and the gate facing edge 20a; and the rear edge 19b and the opposite edge 20b.
• the bearing frame 11 is the main structural component of the gate post 10 and as such needs to be able to bear the weight and forces associated with a closure member 3 mounted thereon.
• the bearing frame 11 is generally an integrally formed component. This may be achieved by extruding the bearing frame 11 from a metal, e.g. aluminium. This may also be achieved by hot-rolling or cold-rolling a seamless metal, e.g. steel, tube. The various openings and cut-outs described later may be created by removing excess material (e.g. by laser cutting, milling, etc.) from the extruded, hot rolled or cold rolled metal tube.
• Suitable thicknesses may be used for the metal of the bearing frame 11 with suitable values being between 1 mm and 1 cm, for example 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm or 9 mm. The thickness depends also on the specific metal used and the manufacturing technique.
• each corner of the bearing frame 11 comprises two parallel wall sections with a 180° fold. Due to this shape, each corner has a high rigidity and strength and does not easily buckle under high pressure.
• each parallel wall section may overlap in the depth direction 17 for about 1 cm to 3 cm and may be separated by a distance in the width direction 16 of about 0,5 cm to 2 cm.
• This shape provides a very high rigidity thus avoiding to use very thick metal sheets (e.g. 2 cm or more) to form the bearing frame 11. Such thickness, while providing the desired strength and rigidity, would negatively impact the weight, costs, size, etc. of the bearing frame 11.
• both the rear wall 20 and the front wall 21 of the bearing frame 11 are provided with a recessed area 22 which forms a substantially flat area in which a repeating pattern of openings is provided.
• the repeating patter is better shown in figure 3 .
• the recessed area 22 is advantageous for various reasons (e.g. improve rigidity of the bearing frame 11 as set out above or to dispose a cover profile therein as described below), the repeating pattern of openings could also be used in non-recessed bearing frame 11 where the rear wall 20 and/or the front wall 21 are substantially planar between their edges.
• the repeating pattern of openings comprises a mainly rectangular cut-out 24 with three openings 25, 26 adjacent the cut-out in the upright direction 15.
• the rectangular cut-out 24 has an upper edge 24a, a lower edge 24b, a gate facing edge 24c, an opposite edge 24d, and four corners 24e.
• Each cut-out 24 is provided with two diagonal buttresses 27 that are integrally formed with the remainder of the wall 20, 21 in which the repeating pattern of openings is provided.
• the diagonal buttresses 27 improve rigidity and strength of the bearing frame 11 in comparison to a similar bearing frame where each cut-out is fully free of material.
• each rectangular cut-out 24 is symmetrical about a middle upright plane as well as a middle horizontal plane. This symmetry aids in providing a flexible design bearing frame 11 that may be used for supporting closure members on either side. Asymmetry may lead to a local pressure differences that may be more susceptible to buckling, crumpling, etc. (i.e. unwanted deformation).
• the main purpose of the rectangular cut-outs 24 is to provide space in the wall 20, 21 to allow a functional component to extend into the bearing frame 11.
• a mechanic installing the gate post 2, 4 has to manually remove the buttresses 27 of one or more cut-outs 24. This may be most easily achieved by sawing the footpoint edges of each buttress 27, e.g. using a circular saw tool. This avoids that complex tools (e.g. a laser cutter) are needed.
• the main purpose of the opening 25, 26 is to fix functional and/or structural components to the bearing frame 11.
• Different reference numbers have been used to denote the three openings, namely reference number 25 for the outermost openings which will further be referenced as the opening pair, and reference number 26 for the central opening.
• the opening pairs 25 are mainly used to fix structural components (e.g. a mounting foot, a top cover, front and back covers, a hinge assembly, a gate closer or actuator, etc.) to the bearing frame 11
• the central opening 26 is mainly used to fix functional components (e.g. a cover lock, an electrical enclosure, etc.) to the bearing frame 11.
• this division need not be exclusive and the central opening 26 is typically used when one of the openings of the opening pair 25 is not available or accessible.
• Each opening 25, 26 is dimensioned to receive a threaded fastening member.
• the use of circular openings 25, 26 is advantageous, albeit not necessary.
• the openings 25, 26 are dimensioned to receive M8 threaded fastening members.
• the opening pairs 25 are symmetrical about the middle upright plane and the opening pairs 25 are mutually aligned in the upright direction 15. This allows identical structural end/or functional components to be fixed on the bearing frame 11 at different height locations without modification. It will be appreciated that the opening pairs 25 could be misaligned with the width direction with tolerances of up to 10° offset being possible so that either the left or the right opening is higher or lower than the other.
• clip nuts 28 are provided.
• An example of such a clip nut 28 is shown in figure 8 .
• the clip nut 28 generally has a clip section 28a and a nut section 28b which provides an inner threaded area.
• the clip section 28a is formed by a U-shaped member in the illustrated embodiment so that this may easily be clipped on a free edge of the mainly rectangular cut-out 24.
• each cut-out 24 is relatively open thus allowing to place the clip nut 28 on the horizontal sidewall 24a, 24b first and then slide it along this sidewall to align with the opening pair 25.
• the buttresses 27 occupy at most 50% of the middle area A. The same may be achieved by having the maximal separation distance d between the buttresses 27 and the sidewalls 24a, 24b at least 1 cm or at least 25% of the height H of the cut-out 24.
• the height H of a cut-out 24 may be anywhere between 3 cm and 15 cm, for example 5 cm, 6 cm or 7 cm.
• the height H i of the central part of the diagonal buttresses 27 is dependent on the height H of the cut-out and may for example be 2 cm or 3 cm.
• the width W of a cut-out may be anywhere between 5 cm and 30 cm, for example 8 cm or 10 cm or 12 cm.
• each cut-out 24 is provided with a V-shaped buttress 27 or an inverse V-shaped buttress 27.
• the resulting rectangular cut-out (denoted by a dotted line in figure 35C ) has diagonal buttresses 27 in a cross-shape.
• the opening pairs 25 in figure 35C are also in the form of a rhombus in which a cage nut or the like may be inserted to provide a threaded area.
• all functional and/or structural components may be mounted to the bearing frame 11 only by means of threaded fastening members, clip nuts 28 and sawing to remove excess buttresses 27. Importantly, no welding is required. As such, the entire bearing frame 11 can have its final finish (e.g. powder lack) already applied during the manufacturing process.
• a mounting foot is provided.
• a first kind of mounting foot is not visible from the exterior of the gate post 2, 4 as in the closure system 1 shown in figure 1A . This invisible mounting foot is described in relation to figures 4 and 5 .
• a second kind of mounting foot is partially visible from the exterior of the gate post 2, 4 as in the closure system 1 shown in figure 1B . This flange-based mounting foot is described in relation to figure 6 .
• the mounting foot is regarded as a structural component of the gate post 2, 4.
• Figure 4 illustrates a first mounting foot 29 designed to be non-visible from the outside of the gate post 2, 4.
• the mounting foot 29 has a general H-shaped horizontal cross-section best shown in figure 5 with elongated openings 34 in the bottom plate to fix the mounting foot 29 to the ground surface.
• the mounting foot 29 has a front wall 29a, a back wall 29b which is generally parallel to the front wall 29a, and a web 29c connecting the walls 29a, 29b.
• the walls 29a, 29b extend in the width direction 16 whereas the web 29c generally extends in the depth direction 17.
• the walls 29a, 29b are parallel to and adjacent a respective one of the front wall 21 and back wall 20 of the bearing frame 11.
• the large contact surface area between the walls 29a, 29b of the mounting foot 29 and the walls 20, 21 of the bearing frame 11 aid in securely placing the bearing frame 11 and thus the gate post 2, 4.
• the mounting foot 29 is provided with elongated slots 32 in the walls 29a, 29b in which nut elements 31 are slidably placed. These nut-elements 31 provide a threaded area in which threaded fastening members 30 are received.
• a few elongated openings 33 are provided which allow fastening members 30 to extend therethrough.
• various of the opening pairs 25 are in the bearing frame walls 20, 21 allow placing a threaded fastening member 30 therein which extends into the nut elements 31 thus fixing the bearing frame 11 to the mounting foot 29.
• the use of elongated openings and slots allows to vary the position of the bearing frame 11 to the mounting foot 29 in the upright direction 15.
• FIG. 6 illustrates a second mounting foot 29'.
• This second mounting foot 29' has generally rectangular cross-section with walls adjacent the bearing frame walls and a flange foot 35 with openings 34 to fix the mounting foot 29' to the ground surface.
• threaded openings 33 are provided (e.g. by tapping a thread therein) thus allowing threaded fastening members 30 to extend through opening pairs 25 in the bearing frame walls 20, 21 into the mounting foot 29' thus fixing the bearing frame 11 to the mounting foot 29'.
• the main advantage of the flange-based mounting foot 29' is the improved strength and rigidity as compared to the H-shaped mounting foot 29. This is due to the larger cross-sectional area and the flange. In this way, thinner metal may be used for manufacturing the foot 29' (e.g. 3 mm) than the foot 29 which may have a thickness of 1 cm to 2 cm.
• Each mounting foot 29, 29' is preferably at least 15 cm high so that multiple opening pairs 25 overlap with the mounting foot.
• Figure 9 illustrates how an electrical enclosure 36 (which is considered a functional component) may be mounted into the bearing frame 11.
• the electrical enclosure 36 has a base housing 36b to be morticed in the free space 39.
• Clip nuts 28 are provided in line with the central openings 26 to mount the base housing 36b to the bearing frame 11 by means of threaded fastening members 38. This ensures that the base housing 36b is securely fixed to the bearing frame 11. Afterwards, a mechanic may install all required electrical connections, circuitry, fuses, etc. needed (naturally depending on the user-selected functionality) in the electrical enclosure.
• the bottom of the housing 36b has various rubber sealing rings 37 allowing wires to pass through the housing 36b in a leak-free manner.
• the electrical enclosure 36 is sealed by a cover 36a which is attached to the base 36b by means of threaded fasteners 40.
• the fasteners 40 are present in each corner of the cover 36a. This requires the opening pairs 25 to be free as this may otherwise hamper the fasteners 40. Reducing the leakage risk thus requires the base housing 36b to be fastened to the bearing frame 11 by means of the central openings 26.
• FIGS 10 and 11 illustrate how a top cover 41 (which is regarded as a structural component of the gate post 2, 4) may be mounted on the bearing frame 11.
• a generally H-shaped mounting bracket 43 is provided having a front wall 43a, a rear wall 43b and a web 43c.
• the construction of the mounting bracket 43 is generally similar to the mounting foot 29.
• the walls 43a, 43b are parallel and adjacent to the walls 20, 21 of the bearing frame 11 and are provided with elongated slots 46 in which square nuts 44 are slidably received. Threaded fastening members 45 extend through opening pairs 35 in the bearing frame walls 20, 21 into the nuts 44 thereby fixing the mounting bracket 43 to the bearing frame 11.
• the web 43c has a threaded area 47 allowing the top cover 41 to be fastened to the bracket 43 by means of another threaded member 42.
• the mounting bracket 43 and the top cover 41 may be fixed to one another by means of key cylinder (e.g. a Euro cylinder). This improves security as an unauthorized user cannot dismantle the top cover without damaging it. Again the slidable nuts 43 allow for aligning properly in the upright direction 15.
• Figure 12 illustrates a gate closer 48 (which is considered a functional component) inserted into the bearing frame 11.
• the gate closer 48 has an outer housing with threaded openings (not shown) therein to allow fixing the gate closer 48 to the bearing frame 11 by means of threaded fastening members extending through opening pairs 25.
• the gate closer 48 has an arm 49 projecting from the top of the bearing frame 11 (i.e. the top of the gate post 2) to connect to the closure member 3.
• Various gate closers 48 are known in the art (e.g.
• spring biased gate closers as disclosed in in WO 2012/103572 ; hydraulically damped spring based gate closers as disclosed in WO 2018/228729 ; and motor-driven gate actuators as disclosed in WO 2019/048359 ) and may be used in a gate post 2 according to the present invention.
• the diagonal buttresses 27 in one of the rectangular cut-outs 24 may be removed. This provides a free space that allows easily reaching the gate closer 48. A mechanic can thus easily reach the gate closer 48 and make adjustments (e.g. closing speed) thereto. The same space can also enable a user to uncouple the gate closer 48 which is especially useful for motor-operated gate closers 48 which may otherwise maintain the closure member 3 in the closed state during a power failure.
• a hinge 5 i.e. a structural component of the gate post 2
• the gate facing side 18 of the bearing frame 11 is provided with two openings 50.
• a reinforcement bar 51 is positioned inside the bearing frame 11 adjacent the gate facing side 18.
• the reinforcement bar 51 has threaded openings 53.
• threaded fasteners 52 provided on the hinge 5 extend through the openings 50 into the threaded openings 53 thus fixing the hinge 5 to the bearing frame 11 whilst at the same time providing a reinforcing bar 51 to locally strengthen the bearing frame 11.
• the reinforcing bar 51 could be formed as part of the H-shaped mounting bracket 43 thus providing a better connection to the bearing frame 11.
• Figure 15 shows a front view of a cover profile 12 to be attached to the bearing frame 11 in order to form the gate post 2, 4.
• a horizontal cross-section through the cover profile 12 is shown in figure 16 and shows that this cross-section is generally C-shaped. More specifically, in its cross-section, the cover profile 12 has a front side 55 extending between opposing ends 55a, 55b from which two upstanding sides 56 extend backwards between a front end 56a (contiguous with one of the ends 55a, 55b) to a rear end 56b. From each rear end 56b, a back wall section 57 extends inwards to a free end 57a.
• a functional component 8 which has an outer housing in which two (or more) through-openings 63 are provided to receive threaded fastening members 62.

• the threaded area is formed by the placement of a square nut 61 in a slot-like opening 60.
• the mounting bar 59 is placed adjacent the inner wall of the front side 55 with the free ends extending into the C-shaped spaces. In other words, the mounting bar 59 overlaps with the back wall sections 57. By fastening the threaded fastening members 62, the back wall sections 57 are effectively clamped between the mounting bar 59 and the outer housing of the functional component 8. This is best shown in figure 18 which also shows the bearing frame 11 with the front cover 12 disposed in the recessed area 22.

• the mounting bar 159 extends in the width direction 16 between two end faces 169 which fit in between the front side 55 and the back wall sections 57. Adjacent each end face 169, there is a wall section 163 which engages against the back wall section 57.

• FIG. 43 and 44 Another alternative mounting bar 159" is shown in figures 43 and 44 .
• the mounting bar 159" is very similar to mounting bar 159. Common features are the end faces 169 which fit in between the front side 55 and the back wall sections 57; the wall section 163 which engages against the back wall section 57; the holes 165, corresponding slot-like openings 166, and square nut members to allow fastening functional components 8; and the square nut members 161 to allow fastening the threaded member 162'.

• the head 162b engages both the back wall section 657 and the abutment surfaces 150.
• the abutment surfaces 150 act as a stop for the threaded fasteners 162'.
• the back wall sections 57 are clamped between the mounting bar 159", in particular the wall sections 163, and the bolt head 162b.
• FIG. 19 shows the finished gate post 4
• figure 20 shows an exploded view.
• the functional component 8 is itself not fixed to the bearing frame 11 but is fixed to the front cover 12 by means of mounting bars 59 and fasteners 62 in the same way as described above in relation to figures 17 and 18 .
• FIG 18 An alternative cover profile 12' is shown in figure 18 .
• This cover profile 12' still relies on the C-shaped sections 56, 57 when viewed in the horizontal cross-section thus maintaining the advantages of easily mounting functional components thereon.
• the main difference is this cover profile 12' is that the front side 55 is shorter leaving free recesses 68 on either side of the cover profile 12' to the bearing frame 11.
• the upstanding walls 56 are also moved inwards providing a free volume 67 behind each side of the front 55. This free volume 67 may be used to place a LED strip 66 therein thus providing indirect lighting along one or two upright lines in the gate post 2, 4.
• Figure 22 shows another variation of a free gate post 4 where a functional component 8 in the form a videophone is provided.
• the cover profile 12 is split into two separate parts, i.e. an upper cover 12a and a lower cover 12b. Due to the split cover 12, the functional component 8 is fixed directly to the bearing frame 11. To this end, a few cut-outs 24 are removed and clip nuts 28 are placed in two opening pairs 25.
• the functional component 8 has a housing with upper and lower edge 67 in which openings 68 are provided. Threaded fastening members 66 extend through the openings 68 into the clip nuts 28 to fasten the functional component 8 to the bearing frame 11.
• the cover parts 12a, 12b due to their C-shaped cross-sections, further hook behind the edges 27. More specifically, the edges 67 are received between the front side 55 and the back wall sections 57 of the cover parts 12a, 12b. In this way, the end of the cover parts 12a, 12b adjacent the functional component 8 is held in place.
• Figures 23 to 27 generally show how the cover profile 12 is fixed to the bearing frame 11.
• Several mechanism are used in combination in order to have a secure connection. More specifically, there is a lower holding rail set 71 shown in figure 24B , an upper holding rail set 72 shown in figure 24A , and a top cover rim 73.
• top cover rim 73 extends downwards. Once the cover profile 12 is mounted to the bearing frame 11, the top cover 41 is placed on top. In this manner, the top cover rim 73 overlaps with an upper area of the cover profile 12 thus holding the cover profile 12 in place. As described above, the top cover 41 is itself fixed to the bearing frame 11 by means of the H-shaped bracket 43.
• the lower holding rail set 71 is shown in exploded view in figure 25 and comprises a base rail 74, a reinforcing bar 75 and spring-biased edges 76. As shown in the cross-sections of figures 26 and 27 , these components are joined together by threaded fastening members 77 engaging in clip nuts 28 mounted on an opening pair 25 in the bearing frame 11. As best shown in figure 27 , the spring-biased edges 76 hold the back wall sections 57 of the cover profile 12. Furthermore, the base rail 74 may have a wider lower section 74a which, in the width direction 16, extends beyond the upstanding edges 76. In order to position the cover profile 12, it is lifted so that the back wall sections 57 slide behind the wide lower section 74a.
• the upper holding rail set 72 is similar to the lower holding rail set 71 with the exception that a wider section is not practical as the cover profile 12 cannot be lifted and slid behind the upper holding rail set 72.
• the upper holding rail set 72 has a base rail, a reinforcing bar and spring-biased edges which are fixed to the bearing frame 11 by means of threaded fastening members 78 extending into clip nuts 28 aligned with an opening pair 25 in the bearing frame 11. The spring-biased edges thus act as a temporary holding means until the top cover 41 is securely position causing the cover profile 12 to be held by the top cover rim 73.
• Figures 28 to 30 show an additional key cylinder 80 (e.g. a so-called Euro-cylinder corresponding to standard DIN 18252/2020-04) for locking the cover profile 12 to the bearing frame 11.
• the bearing frame 11 is provided with a latch plate 83 that is inserted into a removed cut-out 84 and fixed with fasteners 85 to the central openings 26 adjacent the free cut-out 84 as shown in figures 28 and 30 .
• a mounting rail 86 is fastened to the back wall sections 57 using fasteners 87. This is the same principle as how a functional component 8 is mounted to the cover profile 12.
• the key cylinder 80 is pushed through the cylinder-shaped opening 88 in the latch plate. Actuating the key cylinder 80 causes a rotation of the rotary bit 81 which is then caught behind the latch plate 83 thereby preventing the cover profile 12 from being moved.
• Such an additional key cylinder 80 is especially advantageous when using in conjunction with a hingedly attached cover profile 12 as illustrated in figures 41 and 42 .
• the hingedly attached cover profile 12 may also be used without a key cylinder 80.
• the cover profile 12 is attached to the bearing frame 11 by means of one or more (two in the illustrated embodiment) hinges.
• Each hinge includes a hinge rail 182 fixed to the bearing frame 11. More specifically, as shown in figure 42 , the hinge rail 182 comprises through-openings 183 which align with the openings 25, 26. Threaded fasteners (not shown) are used to fasten the hinge rail 182 to the bearing frame 11.
• the hinge further includes a hinge arm 181 comprising a rod section 185, a first pivot axle 186 disposed in a hole 187 in the hinge rail 182, and a second pivot axle 184.
• the hinge further includes a mounting bar 159'. This mounting bar 159' is substantially the same as the mounting bar 159 with the sole difference that there are no threaded holes 165, but there is a single hole 180 to receive the second pivot axle 184.
