Description

Technical Field

[0001] The present invention relates to a modular, multi-stage attachable and detachable frame system.

Background Art

[0002] European Patent No. 0400345 B1 describes connecting members and frame systems based thereon. According to this document, a wedge-shaped sleeve or wedge is inserted into a tubular strut. These are drawn towards each other by a clamping screw, thus forming a wedge shape in combination with the strut, to form a press-fit connection with a corner member or an internal member. The numerous individual parts of the connecting member can only be manufactured in a complicated manner and require special tools for assembly. The openings located in the corner member or the internal member are always visible and are not aesthetically appealing.

[0003] Connecting members and frame systems based thereon are also described in European Patent No. 1615528 B1. The connecting member for connecting tubular struts comprises connecting members extending from a central member, the longitudinal axes of which lie in a common plane. The connecting member for horizontal arrangement has a basic shape of a rotating cylinder and is provided with at least one connecting recess. The connecting member is connected to the strut by a bayonet lock and twisted. The connection created in this way is fixed by a grub screw.

[0004] To release the lock, loosen the grub screw and then loosen the bayonet lock again.

[0005] The tubular strut for vertical arrangement is screwed through a perforated plate of the central member to a foot or to another tubular strut for vertical arrangement.

[0006] Assembly of individual parts requires a lot of time, and there is a risk that the member will be screwed in incorrectly. It can happen that the screw is tightened excessively or tightened excessively weakly.

[0007] European Patent Application Publication No. 1444912A1 describes a removable snap connection between an elastic component and a rigid component. Thus, the locking member is provided with a sliding sleeve along its shaft for loosening the snap connection. The term "push-to-open" is used for this type of removable connection.

[Modes for carrying out the invention]

[0021] From each central member 1, one to four connecting parts have either rigid connecting parts 2 for horizontal arrangement or elastic connecting parts 4, and the longitudinal axes of these connecting parts are in the same plane and are positioned at a 90° angle with respect to the vertical longitudinal axis of the central member 1. The aforementioned connecting parts 2 are each positioned at an angle of 90° or 180° to each other.

[0022] The tubular connecting member 3 for horizontal arrangement has internal connecting parts at each of its ends that are fitted to the rigid connecting part 2 or the connecting part 4 having an elastic part of the central member 1.

[0023] According to the first modified example, one or two connecting parts having either a rigid connecting part 2 or an elastic connecting part 4 for vertical arrangement, whose vertical axis corresponds to the vertical longitudinal axis of the central member 1, extend from each central member 1.

[0024] The tubular connecting member 3 for vertical arrangement has internal connecting parts at each of its ends that are fitted to the rigid connecting part 2 or the connecting part 4 having an elastic part of the central member 1.

[0025] According to the second modification, each connecting node member is formed in a vertical cylindrical shape and has a perforated plate 6 located in the center, thereby positioning a hole 7 in the center.

[0026] Each tubular connecting member 3 for vertical arrangement has female threads 8 at both ends, and a threaded bolt 9 positioned in the center is screwed into one of the two female threads 8, so that the diameter of this threaded bolt 9 matches the diameter of the hole 7 in the perforated plate 6.

[0027] In other words, in the horizontal direction, the connection is always established between the rigid connecting component 2 and the connecting component having the elastic component 4.

[0028] In the vertical direction, according to the first modified example, the connection is achieved between the rigid connecting component 2 and the connecting component having the elastic portion 4, or according to the second modified example, by screwing the connecting members 8 and 9 together.

[0029] In both the first and second modified examples, it is preferable that the rigid connecting component 2 for horizontal arrangement extends from each central member 1.

[0030] As a result, the internal connecting component of the tubular connecting member 3 has a connecting component having an elastic portion 4.

[0031] However, in both the first and second modifications, the connecting component having the elastic portion 4 for horizontal arrangement can also extend from each central member 1.

[0032] As a result, the rigid connecting component 2 is positioned inside the tubular connecting member 3.

[0033] Possible embodiments based on the first modification described above will be explained below.

[0034] The dimensions shown below should be understood as guidelines for prototypes and still require adaptation and verification before practical application.

[0035] As shown in Figure 1, the connecting node member has a central member 1, from which three rigid connecting components 2 extend horizontally and two rigid connecting components 2 extend vertically.

[0036] The central member 1 and the rigid connecting component 2 are manufactured as individual parts, made from metal or alloy, and preferably chrome-plated.

[0037] The rigid connecting component 2 is fixed to the central member 1 by bolts 17.

[0038] The five cylinders 18 extending from the central member 1 for holding the rigid connecting component 2 have a length of 5.98 mm, an outer diameter of 20.84 mm, an inner diameter of 15.8 mm, and therefore a wall thickness of 2.52 mm.

[0039] Along the length of each cylinder wall, there is a continuous hole 19 in the middle, and on the opposite side, there is a half-hole 20 for mounting and securing a bolt 17.

[0040] One or two holding devices 13 for plates, particularly glass plates, can extend from the central member 1.

[0041] The rigid connecting component 2 has a cylindrical shape with a diameter of 15.8 mm on the side facing the central member 1, and has a continuous hole 22 located in the center of the cylinder 21.

[0042] The rigid connecting component 2 extends away from the central member 1 over a distance of 40.2 mm and is tapered from the initial 6.9 mm to 4.0 mm.

[0043] The rigid connecting part 2 has an inclined tapered notch 14 at its end that extends parallel to or at a 90° angle to the continuous hole 22 located in the center of the cylinder 21. During assembly, the connecting part having the elastic part 4 slides over this inclined tapered notch 14 and is then locked in place.

[0044] The tubular connecting member 3 has an inner connecting part at each of its ends, which has an elastic portion 4 that fits into the rigid connecting part 2 of the central member 1.

[0045] The inner connecting component having the elastic portion 4 is molded as an insert 10. Manufactured from plastic material, the insert 10 has a length of 54.3 mm, an inner diameter of 12.75 mm, and a wall thickness of 1.9 mm. They have an opening 26 on their outside, which fits into the opening 5 of the tubular connecting member 3, through which the elastic portion 4 is visible. They preferably have ribs 11 on their outside along their longitudinal axis. The insert 10 can be press-fitted into the tubular connecting member 3 and further bonded. The insert 10 may be beveled at the end that is press-fitted into the tubular connecting member 3.

[0046] The tubular connecting member 3 may have an additional opening through which the insert 10 can be further secured with a grab screw. The grab screw is preferably countersunk.

[0047] The tubular connecting member 3 has openings 5 ​​arranged in a straight line at each end of the outer wall, and the elastic part 4 is visible through these openings. This straight line extends parallel to the longitudinal axis of the tubular connecting member 3. This straight line and the aforementioned longitudinal axis lie in the same plane.

[0048] Through these openings 5 ​​and 26, the coordinately unlockable connecting components 2 and 4 can be unlocked by the action of bolts applied from the outside.

[0049] In a fully assembled frame system, these openings 5 ​​should be inconspicuous for aesthetic reasons.

[0050] These openings 5 ​​are preferably oriented either inward or downward in the horizontal direction.

[0051] In the vertical direction, when connecting node members are positioned at corners, these openings 5 ​​can be located on the bisector of the inward angle. In the case of connecting node members positioned on the inside, these openings 5 ​​can be oriented inward.

[0052] Depending on the desired orientation of these openings 5 ​​in the fully assembled frame system, the rigid connecting components 2 for horizontal orientation and the rigid connecting components 2 for vertical orientation must be aligned accordingly.

[0053] It is also possible to press-fit the hollow rivet 12 into the opening 5 in the tubular connecting member 3 and the opening 26 in the insert 10, so that the elastic part 4 is visible through them.

[0054] On the one hand, the hollow rivet 12 serves to secure the insert 10 against twisting, while on the other hand, the interconnected components 2 and 4, which can be unlocked in coordination, can be unlocked through the opening of the hollow rivet 12 by the action of a bolt applied from the outside.

[0055] The connecting component, which has an elastic portion 4 within a tubular connecting member 3, is molded as an insert 10, is firmly fixed to the insert 10 at one end over a length of 12.5 mm and across the entire inner diameter of the insert 10, and extends freely, rising up from the inner wall of the insert 10 toward the other end.

[0056] The length of this protrusion is 36.6 mm. An inclined notch 15 that fits into the notch 14 of the rigid connecting part 2 is located at a distance of 15.0 mm from the free end of the connecting part having the elastic part 4.

[0057] Insert 10 can be made from plastic material.

[0058] The tubular connecting member 3 has a circular cross-section with an outer diameter of approximately 19.0 mm and can have a length of 73 cm, 36 cm, or 17 cm.

[0059] The outer diameters of the five cylinders 18 extending from the central member 1 for holding the rigid connecting component 2 and the outer diameter of the tubular connecting member 3 may be the same or slightly different, depending on the desired design.

[0060] The tubular connecting member 3 can be made of steel, preferably chrome steel.

[0061] The following describes possible embodiments based on the second modification described above.

[0062] The dimensions shown below should be understood as guidelines for prototypes and still require adaptation and verification before practical application.

[0063] As shown in Figure 7, the connecting node member has a central member 1 from which three rigid connecting components 2 extend horizontally.

[0064] These rigid connecting components 2 are assembled in the same manner as in the first modified example described above and fixed to the central member 1.

[0065] This central member 1 is formed in a vertically cylindrical shape and has a perforated plate 6 positioned in the center. The holes 7 of the perforated plate 6 are located in the center. The outer diameter of the cylinder 23 is 21.8 mm, and the inner diameter is 19.0 mm, thus resulting in a wall thickness of 1.4 mm.

[0066] The cylinder 23 has an overall length of 25.0 mm, and the perforated plate 6, which is 5.0 mm thick, is positioned 10 mm from the end of the cylinder. The diameter of the holes 7 in the perforated plate 6 is 6.4 mm.

[0067] Therefore, the tubular connecting member 3 for vertical placement is shaped to fit within the free cylinder volume extending from the perforated plate 6.

[0068] One or two holding devices 13 for plates, particularly glass plates, can extend from the central member 1.

[0069] The tubular connecting member 3 for vertical placement has a round cross-section with an outer diameter of approximately 19.0 mm and can have a length of 73 cm, 36 cm, 17 cm, 11 cm, or 6 cm.

[0070] The outer diameter of the tubular connecting member 3 for vertical arrangement matches the inner diameter of the two cylinders 23 that extend vertically from the central member 1.

[0071] The tubular connecting member 3 can be made of steel, preferably chrome steel.

[0072] A 10.0 mm long cylinder is press-fitted into each of the two ends of a tubular connecting member 3 for vertical placement, which has a female thread 8. The diameter of the female thread 8 is 5.2 mm.

[0073] The distance from the end of the pipe to the starting point of the female thread 8 is 2.5 mm.

[0074] The centrally positioned threaded bolt 9 is screwed into one of the two female threads 8, and therefore the diameter of this threaded bolt 9 matches the diameter of the hole 7 in the perforated plate 6.

[0075] The length of the threaded bolt 9 is 27.7 mm. A 4.7 mm long, threadless thick section 24 exists at a distance of 7.0 mm from the first end of the threaded bolt 9 and at a distance of 16.0 mm from the second end of the threaded bolt 9. This thick section 24 serves as a stopper when screwing the threaded bolt 9 into the female thread 8.

[0076] The threaded bolt 9 is screwed into the cylinder 23, which has a shorter thread length of 7.0 mm.

[0077] The end of the tubular connecting member 3 opposite the threaded bolt 9 may have at least two symmetrically arranged mounting notches 16.

[0078] The tubular connecting members 3 for vertical arrangement are preferably rounded at their ends.

[0079] The modular, multi-tiered, and removable frame system according to the first modification described above can be installed as follows, in the form of a shelf having two members in the length direction and three members in the height direction.

[0080] Step 1: Connect the two short tubular connecting members 3 for horizontal placement to the connecting node members located at the corners on both sides, properly equip them, and place them on the work surface.

[0087] Steps 5 and 6 are repeated twice.

[0088] Step 7: At all six locations, install the cover component inside the empty cylinder 18 that extends vertically upward from the connecting node member.

[0089] The desired shelves, lids, back walls, and side walls can be assembled and removed according to the technical standards. Accessories such as drawers, swing doors, or hinged doors can also be assembled and removed according to the technical standards.

[0090] The shelves assembled in this way can be removed as follows:

The topmost item obtained in step 3 is unlocked at all six points by the action of bolts applied from the outside through the upper opening 5 of the tubular connecting member 3 for vertical positioning and the opening 26 of the insert 10, and is lifted simultaneously to disassemble it into its individual parts.

[0093] The six tubular connecting members 3 for vertical placement are unlocked and removed through the lower opening 5 and the opening 26 of the insert 10 by the action of bolts applied from the outside.

[0094] These steps are repeated until all parts have been removed.

[0096] Step 1: Connect the two short tubular connecting members 3 for horizontal placement to the connecting node members located at the corners on both sides, properly equip them, and place them on the work surface.

[0097] Step 2: Connect the short tubular connecting member 3 for horizontal placement to the connecting node member located inside on both sides, properly equip it, and place it on the same work surface between the articles obtained in Step 1.

[0098] Step 3: Place the four long, tubular connecting members 3 between the parts arranged for horizontal positioning, and push all the parts together. In some places, it is necessary to push them together simultaneously.

[0099] Repeat steps 1-3 three times.

[0100] Step 4: For the item obtained in Step 3, place the leg members 25 at all six locations within the cylinder 18 that extends vertically downward from the connecting node member.

[0101] Step 5: Insert the tubular connecting members 3 for vertical placement into the cylinder 23 at all six locations, with the threaded bolts 9 facing forward, in an upward direction, and screw them into the leg members 25.
