Description

[0001] The invention relates to a mounting bracket kit which has two side parts and a middle part which can be attached between these side parts.

[0002] CH 102 929 A shows a trestle with two parallel support frames connected by lockable scissors, allowing them to be positioned at different distances from each other and forming a stable unit. The frames are preferably made of bent profile iron. While the entire trestle can support heavier loads, it is very solid and heavy, making it unsuitable for mobile use.

[0003] DE 29 607 681 U1 shows an assembly stand designed to facilitate the installation of door frames. The assembly stand consists of two rectangular frames whose vertical legs are extended downwards to form feet, and which are in turn connected to each other by hinges along the contact lines running along their upper sides. A strip is arranged on the front side of one of the two frames, which in turn is provided with upwardly open recesses adapted to the profile dimensions of the frame legs. A hinged storage panel is attached to the front side of the other of the two frames. This assembly stand is simple in design, but not suitable for heavy loads and is configured only for specific use in the installation of door frames.

[0004] DE 20 2010 010 464 U1 describes a work and assembly trestle with two posts that are oriented vertically, arranged parallel to each other, and connected by a horizontally oriented connecting strut. The lateral posts have a first column element that forms a unit with the connecting strut, and a second column element that forms a unit with a base. The first column element and the second column element are adjustable relative to each other to change the length of the corresponding post and can be locked to each other by means of a locking device. The first column element has a central hollow space with a circular cross-section, into which the corresponding second column element extends from below and is guided for adjustment.The central cavity in the first column element is formed with a longitudinal groove for an extension element that protrudes laterally from the second column element and is intended to guide the second column element in a linearly adjustable and anti-twist manner. The second column element is designed with spaced-apart locking holes. Each post is assigned its own locking device on the connecting strut, allowing the length of the two posts to be adjusted independently of each other. While this assembly stand allows for variable height adjustment, it requires complex guided parts that are costly and prone to maintenance.

[0005] Based on the prior art, it is an object of the invention to provide an improved assembly stand kit which can be used flexibly, can carry high loads despite its low weight, can be manufactured inexpensively and can be quickly disassembled into individual parts with little space requirement for easy transport.

[0006] This object is achieved by a mounting bracket kit according to the appended claim 1. The subclaims identify preferred embodiments. Further details and advantageous embodiments are set forth in the following description.

[0007] The mounting stand kit according to the invention consists of two side parts and a middle part, which, when assembled, form a mounting stand. Each of these two side parts is preferably made in one piece from plastic and has a holding section extending in the direction of a longitudinal axis and having a plurality of receiving openings running parallel to the longitudinal axis. The longitudinal axis preferably forms an axis of symmetry of the side part, and the receiving openings are arranged along this axis of symmetry. Each side part also has a foot section extending in the direction of a transverse axis, the transverse extension of which is preferably shorter than the longitudinal extension of the holding section. The longitudinal axis and transverse axis preferably run perpendicular to one another, so that the holding section preferably extends perpendicularly away from the foot section.Each side panel has numerous raised stiffening structures that extend above a main extension plane of the side panel. The stiffening structures are positioned such that they dissipate the forces introduced at the receiving openings - when the middle panel engages the receiving openings - into the surrounding material, in particular for the distributed dissipation of the forces towards the base section. The middle panel is also made of plastic; it can be removably suspended between the two side panels to assemble the mounting frame. The middle panel has several suspension sections on each of its two short sides, which are shaped such that they can be suspended into the receiving openings of the holding sections of the two side panels. The side panels each have at least as many receiving openings as there are suspension sections on one side of the middle panel.Preferably, however, more receiving openings are provided in the side part than suspension sections on one side of the middle part, so that the middle part can be suspended at different heights in the middle part. Furthermore, the middle part has numerous raised stiffening structures that extend above a main extension plane of the middle part. The stiffening structures are positioned such that they dissipate the forces introduced at the suspension sections into the surrounding material of the middle part. The stiffening structures are preferably arranged on both sides of both the middle part and the side parts.

[0008] By assembling two side panels, preferably of identical design, and a center section, the mounting stand kit creates a mounting stand that's very easy to assemble and disassemble. No separate mounting components, such as screws or clamps, are required; simply hook the center section's mounting sections into the side sections' receiving sections. Once disassembled into its three plate-shaped sections, the mounting stand can be easily and compactly transported, for example, in the trunk or cargo area of ​​a vehicle.

[0009] Preferably, the suspension sections and the receiving sections have complementary engagement areas, in particular grooves, which ensure a positive and force-locking engagement when the parts of the assembly stand are assembled. The center section is thus securely and securely suspended in the side sections.

[0010] The stiffening structures are particularly advantageous in optimizing force absorption and force dissipation in the parts of the assembly stand. The stiffening structures preferably extend across the majority of the surface of the respective part, whereby the material thickness between the stiffening structures can be reduced, so that the stiffening structures rise above the main extension plane of the respective part. These stiffening structures allow for precise control of force introduction and force distribution in the respective part by adjusting their number, orientation, and strength to the maximum forces encountered. This means that the side parts and the center section need to be made thinner overall to absorb predetermined loads / forces. This significantly reduces the overall weight of the assembly stand kit.In principle, the expert is familiar with the dimensioning approaches required for the precise positioning and dimensioning of the stiffening structures, so only exemplary information is required here. In any case, it must be ensured that the maximum permissible applied forces do not lead to deformation or fracture of the side panels or the center section at any point.

[0011] According to a preferred embodiment, the stiffening structures on the center section and the side sections are arranged such that several ribs extend at an angle to each other, and the ends of several ribs preferably meet in a ring structure. The specific design of the stiffening structures preferably takes into account both the number of ribs and their wall thickness, depending on the specific mechanical load for which the mounting bracket kit is to be designed.

[0012] According to an advantageous embodiment, additional stiffening structures in the longitudinal and transverse directions are provided, particularly in the area of ​​the contact surfaces between the central part and the side parts, since increased forces from different directions must be absorbed in these areas.

[0013] Typically, in practical use, two or more assembly stands are assembled from a single assembly stand kit, which then serve as a support for running boards or components to be worked on. In these cases, the load on the entire assembly is primarily due to the weight, which is introduced into the center section of each assembly stand and transferred from there to the side panels.

[0014] In preferred embodiments, different plastics can be used to manufacture the parts of the assembly stand kit. Preferably, the center section and side sections are made of the same plastic, but it is also possible to manufacture the center section from a different plastic than the side sections. In preferred embodiments, the parts are made of thermoplastics such as PE, PVC, PP, ABS, PET, or similar. In modified versions, the plastic can be stiffened with carbon fibers, glass fibers, or textile structures. Manufacturing the parts from plastic material in combination with the targeted arrangement of stiffening structures allows for numerous possibilities for efficient, sustainable, and precisely controllable component production for the assembly stand kit.

[0015] The continuous thickness (wall thickness in the main extension plane) of the parts can preferably be approximately 4 mm, combined with stiffening structures, which are preferably arranged on both sides of the parts and each rise 4 mm above the continuous wall thickness. Parts constructed in this way can, for example, support loads of up to 1000 kg on a standard-sized assembly stand. Typical dimensions for the center section are approximately 100 cm long and approximately 80 cm high for the side sections.

[0016] The use of plastic as the material for the center section and the side panels, particularly instead of the previously common materials steel and wood, leads to faster and more cost-effective production and, above all, allows for easy adjustment of the stiffening structures to determine the load-bearing capacity of the parts. Furthermore, the parts are lighter and can be manufactured with high precision. Parts made of plastic exhibit only minor dimensional deviations when exposed to temperature or humidity fluctuations and are long-term stable under a wide range of environmental conditions. The selected plastics are weather-resistant, non-hygroscopic, and preferably also resistant to aggressive media. Since the plastic does not have to meet high purity requirements, recycled material can also be easily processed, and the amount of waste can be minimized.

[0017] The center section and side panels of the mounting bracket kit are preferably manufactured using plastic injection molding. This allows for high volumes and low production costs. The stiffening structures can be molded directly into the parts, largely eliminating the need for post-processing.

[0018] According to a preferred embodiment of the assembly stand kit, the middle section has an outer support beam running straight between the suspension sections on one of its long sides and a V-shaped angled support receptacle on the other of its long sides. The suspension sections are preferably designed so that the middle section can be suspended into the side sections with both the support beam and the V-shaped support receptacle facing upwards. The assembly stand can therefore be assembled with the middle section rotated around its longitudinal axis, enabling different support options for flat components (on the support beam) and for angled, round, or cylindrical components (in the V-shaped support receptacle).

[0019] An advantageous embodiment is characterized in that one or both side parts have at least four receiving openings in their respective holding section, which extend axially symmetrically to the longitudinal axis and are spaced apart from one another in the longitudinal direction. In contrast, the middle part preferably has three suspension sections on each short side. All receiving openings are preferably identically shaped, and all suspension sections are complementary to the receiving openings and preferably identically shaped. This makes it possible to suspend the middle part at different heights in the side parts in order to vary the working height of the assembly stand, i.e., the height of the support beam or the V-shaped support mount above the support plane.

[0020] In a further developed embodiment, one or both side parts have a receiving opening in their respective holding section that opens toward the free end of the holding section. This provides another positioning option for the middle part.

[0021] In a preferred embodiment, complementary engagement areas are provided at the receiving openings of the side parts and the suspension sections of the center part. This improves the stability of the assembled assembly stand.

[0022] It is advantageous if the two side parts and the central part have the same thickness, whereby this thickness is at least 80 times less than the extension of the side parts in the direction of their longitudinal axis.

[0023] Further advantages and details of the invention will become apparent from the following description of preferred embodiments, with reference to the drawings. Fig. 1 a perspective view of an assembled mounting stand with the parts of a mounting stand kit according to the invention according to a first embodiment; Fig. 2 a top view of a side part of the mounting bracket kit according to Fig. 1; Fig. 3 a plan view of a middle part of the mounting bracket kit according to Fig. 1; Fig. 4 a perspective view of a step-assembled mounting stand with the parts of the mounting stand kit according to Fig. 1; Fig. 5 a perspective exploded view to illustrate different assembly options of the parts of the assembly stand kit.

[0024] Fig. 1 shows a perspective view of an assembled assembly stand consisting of parts of a first embodiment of an assembly stand kit according to the invention. In the simplest case, the assembly stand kit consists of two side parts 01 and a center part 02. The side parts 01 and the center part 02 are made of plastic, preferably using an injection molding process. In the assembled state, the center part 02 extends between the two side parts 01 and is suspended therein. This illustration shows that the three parts 01, 02 of the assembly stand kit each have a plate-like basic shape, i.e. the thickness of the parts is significantly less than the respective width and length dimensions of the part.

[0025] Fig. Figure 2 shows a top view of one of the two side panels 01 of the mounting bracket kit. The side panel 01 extends longitudinally along a longitudinal axis L. s, which in the illustrated embodiment forms the axis of symmetry of the side part. In modified embodiments, the side part can be constructed asymmetrically. A longitudinal axis L S The holding section 05 extends essentially over the entire length of the side part and has a plurality of receiving openings 06 extending parallel to the longitudinal axis and spaced from one another. In the direction of a transverse axis perpendicular to the longitudinal axis L SA foot section 07 of the side part extends, the transverse extent of which is preferably shorter than the longitudinal extent of the holding section 05; for example, the transverse extent is approximately half as long as the longitudinal extent. The foot section 07 has, for example, two support surfaces 08 on which the side part stands when the assembly stand is assembled. The foot section 07 and the holding section 05 merge into one another in a base area 09. In the embodiment shown, the lower of the receiving openings 06 extends in the base section 09 into the foot section 07.

[0026] The side part 01 has numerous raised stiffening structures 10, which are positioned such that they dissipate the forces introduced at the receiving openings 06 into the surrounding material of the side part 01. In the embodiment shown, the stiffening structures 10 comprise both rib structures 10a, which extend in a straight line, and ring structures 10b, which are essentially circular in shape and from which several rib structures 10a originate or end. The rib structures 10a can be arranged parallel to the longitudinal axis L. Sor also extend at an angle thereto. The rib structures 10a preferably extend between two ring structures 10b or between a ring structure 10b and another rib structure 10a or between an outer boundary 11 and a ring structure 10b or another rib structure 10a. The stiffening structures 10 and preferably also the boundary 11 rise above a plate-shaped main extension plane 12 of the side part, preferably on both side surfaces of the side part, as shown in Fig. 1. Preferably, the stiffening structures 10 rise on each side surface approximately by a height corresponding to the thickness of the side part in the region of the main extension plane 12. The side part 01 can, for example, have a thickness of 4 mm.

[0027] The side part 01 has at its free end 13, which is located away from the foot section 07, an open receiving opening 14, which corresponds in width to the other receiving openings 06 and also along the longitudinal axis L S runs.

[0028] Fig. Figure 3 shows the top view of the middle section 02 of the mounting stand kit. A transverse axis Q M of the middle part represents an axis of symmetry, although other embodiments can also be constructed non-symmetrically. In the longitudinal direction, the middle part 02 preferably has a greater extent than in the transverse direction. In order to be able to attach the middle part 02 to the two side parts 01 during assembly of the mounting bracket, several suspension sections 20 are provided on each of the two short sides of the middle part, which are shaped such that they can be suspended in the receiving openings 06 of the holding sections 01 with little play. Due to the relative to the transverse axis QM Due to the symmetrical design, the suspension sections 20 fit the receiving openings 06 of both side parts 01. Therefore, when assembling the mounting stand, the user does not need to worry about assigning a specific side part to the respective short side of the middle part. The suspension sections 20 are designed with a thickness that allows for stable insertion into the receiving openings 06, so that the user can also loosen this connection, preferably without tools, in order to disassemble the mounting stand into its three parts.

[0029] In the illustrated embodiment, engagement areas 21 are provided on the suspension sections 20, which interact with matching material sections on the receiving openings 06 to form a toothing or interlocking, which stabilizes the connection between the side part and the middle part. The middle part 02 has Fig. 3 shown embodiment engagement areas 21a, which are parallel to the transverse axis Q M extending grooves, and engagement areas 21b, which are also shaped as grooves, but at an angle of ±45° to the transverse axis Q M This makes it possible to hang the middle part 02 in the side parts 01 so that the longitudinal axis L S of the side part parallel with the transverse axis Q M of the central part (engagement in the engagement areas 21a) or that these two axes enclose an angle of 45° (engagement in the engagement areas 21b). Different angles are possible in modified embodiments. Those engagement areas not filled by engaging material sections of the side parts are available as storage grooves, for example, for storing workpieces or tools.

[0030] In the illustrated embodiment, the center section 02 has an outer support beam 22 running straight between the suspension sections on one of its long sides and a V-shaped angled support receptacle 23 on the other of its long sides. The suspension sections 20 are also shaped so that the center section can be tilted 180° around its longitudinal axis and, in these two positions, can be hooked into the receiving openings 06 of the side sections. Therefore, either the outer support beam 22 or the V-shaped angled support receptacle 23 points upward, allowing the assembly stand to be adapted to different support tasks.

[0031] Similar to the side parts 01, the center part 02 has numerous raised stiffening structures 10, which are positioned such that they dissipate the forces introduced at the suspension sections 20 into the surrounding material of the center part 02. The stiffening structures 10 of the center part can also include rib structures 10a and ring structures 10b. The criteria outlined above with regard to the side parts 01 apply accordingly to the dimensioning and positioning of the stiffening structures 10 for the center part 02.

[0032] At the Fig. In the embodiment shown in Figure 3, a stiffening beam 24 extends between the outer support beam 22 and the V-shaped support mount 23, on which the two legs of the V-shaped support mount 23 are supported. The two opposite ends of the legs of the V-shaped support mount 23 merge into column-shaped connecting sections 25, which support the plurality of suspension sections 20.

[0033] Fig. Figure 4 shows a perspective view of a step-assembled assembly stand with the parts of the assembly stand kit. Because the middle section 02 has three suspension sections 20 on each short side, while each side section has four receiving openings 06 and an additional open receiving opening 14 at the free end 13, the middle section can be suspended in the side sections at different heights. Fig. In the embodiment shown in Figure 4, the upper suspension section 20 was inserted into the open receiving opening 14 of the side part 01 shown at the front, and the middle and lower suspension sections are inserted into the two upper receiving openings 06 of this side part. In contrast, the upper suspension section of the opposite short side of the middle part 02 is inserted into the uppermost complete receiving opening 06 of the side part shown at the rear. With such a configuration, the assembly stand can, for example, be set up with the two side parts on different steps of a staircase, so that the outer support beam 22 still runs essentially horizontally.

[0034] Fig. Figure 5 shows a perspective exploded view illustrating various assembly options for the parts of the assembly stand kit. The dashed lines with arrows illustrate the possible threading movements that must be performed to hook the center section 02 into the two side sections 01. It can be seen that the hooking sections 20 are first inserted into the receiving openings 06 parallel to the longitudinal axis of the center section 02 and then parallel to the longitudinal axis L. S be lowered in order to achieve a locking or interlocking in the engagement areas 21a, so that the transverse axis Q M of the middle part parallel to the longitudinal axis L S of the side part 01.

[0035] It is understandable that even the Fig. In addition to the mounting options shown in Figure 5, there are further options for assembling the parts of the assembly stand kit. QUOTES CONTAINED IN THE DESCRIPTION
