Abstract
Description
[0001] The invention relates to an arrangement for attaching a mailbox to a wire mesh fence.
[0002] Various solutions for attaching a mailbox to a fence are known in the art. In many applications, the mailbox needs to be attached to a welded wire fence. Welded wire fences consist of vertically and horizontally arranged round bars. The spacing between the vertically arranged bars is smaller than that between the horizontally arranged bars.
[0003] For example, it is known to attach a mailbox to the fence posts at the back using anchor or eye bolts. Emptying the mailbox from the back is not possible due to the existing fence mesh. A further disadvantage is that the mailbox, due to its depth, protrudes from the surface of the fence and may potentially intrude into traffic areas.
[0004] To overcome this disadvantage, it is also known from the prior art to create a cutout in the mesh of the welded wire fence. To create a mounting base for the mailbox, a clamping flange is attached to the bars and bar ends surrounding the cutout. The mailbox is then attached to this clamping flange. A particular disadvantage is that the clamping flange requires a significant amount of material, that this type of installation requires at least two people, and that precise alignment of the clamping flange and the mailbox is difficult.
[0005] The object of the invention is to provide a simple-to-manufacture and easy-to-assemble mounting for a mailbox on a wire mesh fence, which makes it possible to mount a mailbox with different removal configurations, in particular with rear removal and in a modifiable installation depth, especially flush with the front.
[0006] The problem is solved by the features listed in claim 1. Preferred embodiments are set forth in the dependent claims.
[0007] The arrangement for attaching a mailbox to a welded wire fence refers to mailboxes with a classic box-like design. The mailbox is preferably designed as a through-the-wall mailbox, i.e., a mailbox with front insertion and rear retrieval. Mail can then be retrieved from the rear on the private, fenced side. However, the mailbox can also be designed as a front-retrieval mailbox, i.e., a mailbox with both front insertion and front retrieval. The arrangement according to the invention applies to mailboxes in portrait format, landscape format, or, for example, double mailboxes. The mailbox has, in particular, a first side wall and—opposite it—a second side wall. The side walls are arranged perpendicular and simultaneously transverse to a plane of the fence.
[0008] The arrangement, according to the invention, is designed for attachment to a welded wire fence. Welded wire fences, in particular double-wire fences, are also understood to be welded wire fences. Welded wire fences have become established for enclosing properties. Both private and commercial properties are enclosed with such fences. The welded wire fence has a grid-like arrangement of a plurality of vertical and a plurality of horizontal wires. This results in a mesh panel that defines the plane of the fence. The vertical and horizontal wires are arranged in a close grid, with the vertical wires generally having a smaller spacing than the horizontal wires. In particular, the arrangement according to the invention relates to double-wire fences with a grid of 200 mm for the horizontal wire spacing and 50 mm for the vertical wire spacing, where a tolerance of plus / minus 3 mm is common.For the purposes of the present invention, the outside of the welded wire fence is understood to be the side facing the public space, and the inside of the welded wire fence is understood to be the side facing the enclosed space.
[0009] Furthermore, the welded wire fence has a cutout designed for the placement of a mailbox on a single fence surface. This cutout is typically made by cutting the relevant wires with an angle grinder or a hacksaw.
[0010] The cutout is dimensioned to accommodate the mailbox with additional clearance. This cutout allows for the installation of a mailbox with an opening back panel. This enables the mail carrier to conveniently fill the mailbox from the publicly accessible exterior. Simultaneously, the mail can be retrieved from within the enclosed space by opening the back panel on the inside. Alternatively, a mailbox with front access can also be installed.
[0011] Insofar as numerals such as first, second or similar are used in the description and in the claims, this does not serve to indicate a specific hierarchy or value, but merely for unambiguous identification and assignment.
[0012] The arrangement according to the invention comprises a pair of base bodies, consisting of a first base body and a second base body, and a retaining clip arrangement. The mailbox and the welded wire fence themselves are not components of the arrangement according to the invention. However, due to their intended functional interaction with the components of the arrangement according to the invention, they are relevant for the nature and understanding of the features of the invention.
[0013] The pair of base bodies consists of a first base body and a second base body. The two base bodies are arranged on either side of the mailbox and are essentially mirror-symmetrical to each other. The base bodies serve as a mounting base for the mailbox and are, in turn, attached to the welded wire fence in accordance with the invention.
[0014] The first base body is assigned to the first side wall of the mailbox and the second base body is assigned to the second side wall of the mailbox.
[0015] The first basic body is designed to encompass, at least partially, a first vertical rod. For this purpose, the first basic body has a vertically extended U-shaped base. To form the U-shaped profile, the basic body has a first base leg, a first inner leg which connects to the base leg on one side, and a first outer leg which connects to the first base leg on the other side and is opposite the first inner leg.
[0016] The first base leg is designed for a plane parallel to the fence surface. When installed correctly, the inside of the first base leg faces the outside of the welded wire fence.
[0017] The first inner leg is designed for a plane-parallel arrangement with the first side wall of the mailbox and is at a substantially right angle to the first base leg. Furthermore, the first inner leg has mounting holes for spaced attachment to the first side wall. This allows the mailbox to be attached to its first side wall on the first inner leg – preferably using special spacer bolts.
[0018] The first outer leg has at least one recess contour designed to receive a first horizontal bar. The recess contour is hook-shaped. This allows the base body to be hooked into one of the horizontal bars, hereinafter referred to as the first horizontal bar.
[0019] The opening of the U-shaped profile faces the inside of the welded wire fence. The U-shaped profile encloses a vertical bar on three sides, which will be referred to below as the first vertical bar.
[0020] The second base body is designed to be arranged in a vertically extended, U-shaped profile, mirror-symmetrical to the first base body, and partially encompassing a second vertical bar. This ensures the mailbox is held symmetrically within the opening of the wire mesh fence. The second base body has a second base leg, a second inner leg, and a second outer leg. The descriptions of the first base body apply analogously to the second base body.
[0021] Thus, the second inner leg is designed for a plane-parallel arrangement to the second side wall of the mailbox and has second mounting holes for spaced attachment to the second side wall. Furthermore, the second outer leg has at least one second recess contour designed to receive a second horizontal bar. The second base body is hooked into this hook-shaped recess contour and thus secured in its position by the vertical load transfer through the second horizontal bar.
[0022] The second basic body is mirrored to the first basic body and, like the first basic body, also surrounds a vertical rod with its U-profile shape, which is referred to below as the second vertical rod.
[0023] By enclosing the first and second vertical bars and hooking it onto the first and second horizontal bars, a properly assembled assembly consisting of the two base bodies and the mailbox is already fixed in all degrees of freedom - except only with regard to one linear degree of freedom in an excavation direction unilaterally upwards.
[0024] The retaining clip assembly consists of several first retaining clips assigned to the first base body, and several second retaining clips assigned to the second base body. The retaining clip assembly is used to determine the final position of the fastening assembly on the welded wire fence.
[0025] Each of the first retaining clips is positioned between the first inner leg and the first outer leg. The first retaining clips each have a first support web and a first tensioning bracket. The first tensioning bracket is designed to clamp the first vertical rod between the first support web and the first tensioning bracket.
[0026] Each of the second retaining clips is arranged accordingly between the second inner leg and the second outer leg. The second retaining clips each have a second support web and a second clamping bracket, designed to clamp the second vertical rod between the second support web and the second clamp.
[0027] All retaining clips are preferably constructed in the same way. They serve to ensure that the mailbox is mounted without play and that it cannot be unhooked. Preferably, at least one retaining clip is arranged on each of the two base bodies in such a way that it is positively engaged with one of the horizontal bars and, in the upward direction of extension, this positive engagement prevents it from being lifted out.
[0028] The mailbox is securely attached to the fence opening. The retaining clips are preferably made of plastic, and fiber-reinforced plastic is particularly preferred.
[0029] The fastening arrangement according to the invention provides an advantageous solution for the fastening of conventional mailboxes compared to the prior art.
[0030] The ease of assembly is a particular advantage. In particular, only one person is required for installation. In the first step, the two base units are attached to the mailbox, and then the pre-assembled mailbox and base unit is simply hung in place. Final securing is then achieved using the mounting clips. Conversely, the mailbox can also be attached to the base units later. Similarly, the mailbox can be removed from the base units without having to remove the base units from the wire mesh fence.
[0031] Another advantage is that assembly can be done without tools.
[0032] The base bodies are advantageously arranged with the outer surface of the base leg facing outwards. This protects the retaining clips from access from the outside. Furthermore, the outer surface is completely closed, eliminating any risk of injury.
[0033] Furthermore, a visually appealing solution is available. The length of the base units can also be easily adjusted to the mailbox height.
[0034] The retaining clips are preferably made of plastic. This prevents the risk of contact corrosion at the cut ends of the bars of the welded wire fence.
[0035] The fastening arrangement according to the invention is advantageously scalable in a simple manner. This allows for the mounting of mailboxes of different sizes, as well as, if necessary, two or more mailboxes stacked on top of each other, and grouped mailbox systems. Furthermore, by selecting the length of the fastening bolts between the base bodies and the side walls of the mailbox, an adjustment between the mailbox width and the grid dimension of the vertical struts of the welded wire fence can be easily achieved.
[0036] The mailbox can be advantageously positioned so that it is entirely within the property line. This prevents it from protruding from the fence line into public space. Therefore, if the fence is erected directly on the property line, this effectively prevents the mailbox from encroaching on the property boundary or, in the case of an adjacent public road, from violating any building regulations or other safety requirements.
[0037] By specifying the arrangement of the mounting holes in the side walls of the mailbox, the mailbox's position relative to the fence plane can be selected in a structurally simple manner. This allows not only for the mailbox to be mounted flush with the fence plane on the outside, but also, depending on the user's preference, further outwards, for example, centered on the fence plane. This also makes it possible to install mailboxes with a top-loading mail slot, also known as top-loading mailboxes.
[0038] Furthermore, the base bodies and the retaining clip can be manufactured cost-effectively and transported in a space-saving manner.
[0039] According to an advantageous further development, the arrangement for attaching a mailbox to a welded wire fence is characterized in that the first outer leg has a further first recess contour and is designed to receive a third horizontal bar. This is arranged parallel to the first horizontal bar.
[0040] According to this further development, the second outer leg also has a further second recess contour, which is designed to accommodate a fourth horizontal bar. This is arranged parallel to the second horizontal bar.
[0041] In addition, several further recesses can be provided for additional horizontal bars.
[0042] The additional cutouts further stabilize the assembly and ensure that mailboxes of different sizes, or entire mailbox systems with integrated doorbells for apartment buildings, can be mounted in the fence. The excellent scalability of the base units is a particular advantage over other solutions.
[0043] According to a further advantageous embodiment, the arrangement for attaching a mailbox to a wire mesh fence is characterized in that the support webs of the retaining clips are attached to the respective inner leg and to the respective outer leg by means of a tool-free clip spreading tongue.
[0044] The expanding tongue is designed as a clip, with a chamfer bending it in the insertion direction. This allows the support web to be inserted into the corresponding opening in the base body. In the removal direction, a barbed contour prevents it from being pulled out. This design offers the advantages of simple, tool-free assembly and protection against unauthorized loosening of the connection.
[0045] According to an advantageous further development based on this, the arrangement for attaching a mailbox to a welded wire fence is characterized in that the tensioning brackets are attached to the respective support bars by means of a tool-free clip mushroom head bolt and the clip mushroom head bolt, in an engaged state, prevents the clip spreading tongue from being released.
[0046] Following this advanced training, a fastening system is provided in which the integrated clip-type mushroom-head bolts serve two purposes: firstly, to securely anchor the clamping bracket to the support web, and secondly, to provide a locking mechanism that reinforces the attachment of the support web to the base body and prevents loosening. Furthermore, the integrated clip-type expanding tongue also provides two functional components: firstly, an elastically deformable section for tool-free and backlash-free coupling of the support web to the base body, and secondly, an elastically deformable section for tool-free and backlash-free coupling of the clamping bracket to the support web.
[0047] In a further advantageous embodiment, the arrangement for attaching a mailbox to a double wire fence is characterized in that the arrangement has a plurality of bolt bodies which are designed for engagement in a respective fastening bore and for spaced-apart fastening to a respective side wall.
[0048] The bolt bodies allow for tool-free attachment of the mailbox to the base. The advantage here is that installation is very simple and quick. Furthermore, unauthorized removal of the mailbox cannot be carried out without causing damage. This makes sabotage more difficult, and any such action would be immediately detected due to the damage. Additionally, the bolt bodies allow the desired distance between each side panel of the mailbox and the base to be precisely set.
[0049] The invention is described as an embodiment by reference to Fig. 1. Schematic oblique view of the arrangement for attaching a mailbox to a double wire fence from a first side Fig. 2. Schematic oblique view of the arrangement for attaching a mailbox to a double wire fence from a second side Fig. 3. Schematic oblique view of the first basic body with retaining clip arrangement Fig. 4. Schematic oblique view of the second basic body with retaining clip arrangement Fig. 5. Detailed illustration of a retaining clip explained in more detail.
[0050] In this context, identical reference symbols in different figures refer to the same features or components. These reference symbols are used in the description even if they are not shown in the figure in question.
[0051] The Fig. Figure 1 shows in a schematic oblique view an embodiment of the arrangement for attaching a mailbox A to a wire mesh fence B designed as a double wire mesh fence.
[0052] The welded wire fence B has a cutout BA. All horizontal bars BHn and vertical bars BVn have been removed from this cutout. The cutout BA is designed so that it is framed on all sides by bars. The size and shape of the cutout BA are chosen to accommodate the mounting brackets for a mailbox A.
[0053] For fastening, the first base body 10 of the base body arrangement 10, 20 is mounted on the first side wall A1 of the mailbox A at a distance from the first side wall A1 by means of bolt bodies 60n. This, together with its right-angled first base leg 12 and the further angled first outer leg 13, encloses the first vertical rod BV1 adjacent to the cutout BA. This fixes the mailbox A in its horizontal position.
[0054] The first recess contour 15, specifically attached to the first outer leg 13, overlaps the first horizontal bar BH1 located there. The downwardly curved, hook-shaped recess contour 15 is designed as a grid of hooks and, due to gravity, engages not only in the first horizontal bar BH1, but also in other horizontal bars, such as the third horizontal bar BH3, by means of the further first recess 15n. This fixes the arrangement in the cutout BA.
[0055] The arrangement is designed so that the front of mailbox A is flush with the outer edge of the welded wire fence B, aligned with the fence plan BP. Mailbox A thus projects into the space behind the inner edge of the welded wire fence B. Therefore, no components protrude beyond the fence plan BP.
[0056] To prevent the mailbox A from being removed from the cutout BA, a retaining clip arrangement 30, 40 is provided, which here has three first retaining clips 30 and - not shown here - three second retaining clips 40, which are snapped into the respective base body 30 or 40 and thus locked there.
[0057] The second side wall of mailbox A has a mirrored arrangement, as is present on the first side wall A1. This ensures that mailbox A is held symmetrically in the opening BA of the welded wire fence B.
[0058] The Fig. Figure 2 shows the embodiment of the fastening arrangement from the perspective of the second side wall A2 of the mailbox A and thus essentially corresponds to the Fig. 1. The descriptive content for Fig. 1 apply accordingly. Fig. Therefore, the second basic body 20 and the second vertical bar BV2, the second horizontal bar BH2 and the fourth horizontal bar BH4 represent the relevant bars of the welded wire fence B.
[0059] The Fig. Figure 3 shows a schematic oblique view of the first base body 10 with a removed retaining clip 30 from the retaining clip assembly 30, 40. The first base body 10 is U-shaped. The first inner leg 11 faces the mailbox A. Accordingly, the first mounting holes 14 are located there. The first base leg 12 is angled at a right angle to this. This forms the basis for the two laterally adjoining first side legs – the first inner leg 11 and the first outer leg 13. The first outer leg 13 is also arranged at a right angle and parallel to the first inner leg 11. In the present embodiment, this leg has a shorter side length than the first inner leg 11. The U-shaped design further encloses a vertically arranged first vertical bar BV1 of the welded wire fence B.The distance between the outer surface of the first inner leg 11 and the outer surface of the first outer leg 13, referred to here as the outer dimension of the side leg, is 50 mm in the present embodiment. Based on the usual grid spacing of the vertical bars BVn of 50 mm, this provides ample mounting clearance in the horizontal direction. This allows mailboxes with widths that are not integer multiples of the grid spacing of the vertical bars to be easily installed. Furthermore, the first recess contour 15 is incorporated in the outer leg 13. The first recess contour 15 is hook-shaped. The hooks serve to engage with the horizontally arranged first horizontal bar BH1. Several additional first recess contours 15n are also incorporated, arranged one above the other, so that further horizontal bars BHn can be engaged, depending on the arrangement and spacing of the fence bars.This ensures that the mailbox is securely fixed. In the present embodiment, the first recess contour 15 and the subsequent first recess contours 15n are arranged in a grid pattern. The grid pattern of the recess contours 15, 15n is aligned with the grid spacing of the horizontal bars BHn of 200 mm such that at least two of the horizontal bars BHn are always encompassed by the recess contours 15, 15n.
[0060] To prevent the mailbox from being detached from the fence structure, a plurality of first retaining clips 30 are used. Rectangular recesses for receiving the first retaining clips 30 are located in the first inner leg 11 and opposite them in the first outer leg 13. These are shown without reference numerals.
[0061] The first retaining clip 30 consists of a first support bar 31, which has two clip spreaders 51 with hooks at the ends. These are clicked into the rectangular recesses in the first side arms 11, 13 in the first base body 10. The first retaining clip 30 also consists of a first tensioning bracket 32. The first vertical bar BV1 of the welded wire fence B is thus clamped between the support bar 31 and the first tensioning bracket 32. The first tensioning bracket 32 is clipped into the first support bar 31 with its mushroom-headed clip 52. This simultaneously locks the clip spreaders 51 of the support bar 31. This effectively prevents the support bar 31 from being unintentionally removed from the rectangular recesses. At the same time, the mushroom-headed clip 52 is firmly engaged. The mailbox is thus securely fixed in the fence opening.
[0062] The Fig. 4 is essentially a mirror image of the Fig. 3 and shows the second basic body 20 and the second retaining clips 40. The descriptive contents for Fig. 3 apply accordingly to the Fig. 4 where the second base body 20, the second inner leg 21, the second base leg 22, the second outer leg 23, the second recess contour 25 and the further second recess contours 25n as well as the second retaining clip 40 with the second support web 41 and the second clamping bracket 42 are shown here.
