Definitions
- connection system in particular for shelf elements, comprising
- At least one horizontal element having a first incision extending from a first incision edge in the direction of a front edge
- At least one carrier element having a second cut extending from a second cut edge toward a trailing edge comprising at least one horizontal element, with a first incision, starting from a first incision edge, and a carrier element having a second incision, starting from a second incision edge.
- connection systems especially for shelves are known in numerous designs. In essence, the differences, e.g. depending on whether the shelf is primarily stable and durable, for example as a heavy-duty shelf, or whether it should be as quick and easy as possible and ready to be dismantled.
- the horizontal elements or the shelves are as firmly as possible and reliably connected to the horizontal support elements, for example with screw or adhesive connections.
- the connecting means are minimized. Often, plug connections or simplified screw connections are used.
- connecting means is crucial, from which material the horizontal and / or support elements.
- suitable connecting means In a wooden shelf, for example, also provide adhesive or nail connections.
- shelf crosses are known in this context, which are connected at the back to the horizontal and / or carrier elements in order to prevent lateral tilting of the shelf.
- a continuous rear wall be provided, which is fastened to the back of the horizontal and / or support elements. Even such a rear wall prevents the lateral tilting of the shelf.
- such shelves can also be attached to a wall in front of which they are positioned.
- connection system which requires no tools whatsoever and with which a shelf can be constructed which can be positioned completely free-standing in the room and still has a relatively high load-bearing capacity.
- the object of the present invention is to provide a connection system for furniture, in particular shelves, which allows a quick and easy construction. It is essential that no tools have to be used for assembly and disassembly.
- the piece of furniture constructed with the help of the connection system should be able to stand freely in the room, the carrying capacity should be sufficiently high.
- connection system with the features of claim 1.
- connection system is particularly suitable for shelves with shelves and carrier elements, but it is also suitable for all other pieces of furniture in which such a connection seems expedient.
- the invention is based on a plug-in system already known from the prior art, with which, for example, boards can be connected to one another to form a cross-connection.
- both boards each have an incision starting from an incision edge.
- the two boards usually a horizontal element and a carrier element, can be inserted into each other via these cuts.
- the depth of the cuts can be selected as needed so that the boards after assembly at least on one side flush with each other.
- the width of the incisions preferably corresponds to the thickness of the respective other boards, so that they have the tightest possible fit in the assembled state, which prevents unwanted movements (shaking).
- the horizontal element and the carrier element have such cuts, so that a corresponding cross connection is formed.
- a corresponding cross connection is formed.
- both elements can have any number of corresponding cuts.
- the two incisions each have incision inner surfaces which are defined as follows:
- the horizontal element has a right incision inner surface and a left incision inner surface, and a recessed first end surface.
- the support member has an upper incision inner surface, a lower incision inner surface, and a recessed second end surface.
- the relative position information refers to the mated state in which the two end faces of the two elements abut each other.
- the horizontal element has a groove in the cut-in edge in the region of the first cut. This runs substantially parallel to the longitudinal extent of the horizontal element, ie in the assembled state of the elements substantially horizontally.
- the groove is preferably arranged directly adjoining the first recess and opens into it.
- two grooves are provided, each of which opens into the cut opposite each other on the right or left.
- the carrier element has, on the edge opposite the cutting edge, hereinafter trailing edge, at least one pin which cooperates laterally with the groove of the horizontal element and projects laterally out of the carrier element.
- the diameter of the pin and the width and depth of the groove are matched to one another such that the pin is held as firmly as possible in the groove in the assembled state of the two elements.
- the carrier element also preferably has two pins lying opposite one another and projecting laterally from the carrier element. According to the invention, therefore, the horizontal element with the at least one groove and the carrier element with the protruding pin are pre-produced, so that the piece of furniture, for example a shelf, only has to be squeezed together by the user. Alternatively it can be provided that the user only has to insert the pin into an opening or bore of the carrier element before assembly.
- the setup is extremely quick and easy in both cases. In particular, the shelf can also be dismantled just as quickly and easily.
- connection system leads to two load-bearing support points or contact areas, namely by the support of the horizontal element on the lower incision inner surface of the support element and by the support of the at least one pin in the groove.
- the pin in the groove also acts as a rotation safeguard, which prevents twisting of the two elements (tilting).
- the anti-rotation is additionally improved in particular by the formation of two pins per connection, ie to the right and left starting from the support element.
- the horizontal element can also rest only on the pin or pins.
- the pins are therefore not arranged within a groove, but merely serve as a support for the horizontal element.
- the pin is positioned in this case in the assembled state of the elements below the horizontal element, so that it rests on the pin.
- the groove has a substantially rectangular cross section and has a lower inner surface, an upper inner surface and a recessed groove end surface.
- at least one of the two inner surfaces has a depression extending in the longitudinal direction of the groove and thus in the longitudinal direction of the horizontal element.
- the groove has a height which is slightly smaller than the diameter of the pin. This causes an elastic deformation of the material in the region of the groove and / or the pin when inserting the pin. The pin is thus held firmly in the groove in the assembled state. In the event that a recess for the pin is provided within the groove, the elastic deformation causes the pin is additionally pressed into the recess and held in this.
- the horizontal element can preferably be made of wood, so that the groove can be introduced into the incision edge, for example by means of a saw blade of a circular saw.
- This process is fast, easy and precise feasible.
- the recess can be introduced within the groove for receiving the pin by a second sawing process, in which the saw blade is introduced, for example, obliquely from above into the existing there groove.
- the upper edge of the groove is slightly removed, as a result of which the slot opening widens slightly.
- the circular disk strikes the upper or lower inner surface of the groove and thus creates the desired depression.
- An angle of incidence of the saw blade of, for example, 30 ° to 60 °, preferably 45 ° has proven to be particularly suitable.
- the removal of the upper groove edge results in an inclined surface, which serves as an insertion aid and has an angle of 110 ° to 150 °, preferably 135 ° to the upper Nutinnen Chemistry.
- connection system according to the invention is particularly suitable for a particularly visually appealing variant of a shelf.
- the thickness or thickness of the horizontal elements exceeds the thickness or thickness of the carrier elements.
- the horizontal elements are significantly wider than the carrier elements, so that the carrier elements in the assembled state do not reach as far as a front edge of the horizontal elements. They are thus reversed and at the same time seen from the front, much narrower. Since no cross connections are necessary for a stabilization of the shelf, so it without Further aids can stand free in the room, resulting in a visually very interesting sight, since the horizontal elements are held at first glance unpaved. This effect is even stronger when the support elements are made of metal, since this can have the lowest possible strength and the shelf is filled with objects, such as books.
- a connection which is as stable as possible can also be achieved according to the invention in that the pins are not straight, but bent along the longitudinal axis to a certain degree. This creates a higher contact pressure between the pin and the groove.
- the pin may for example be formed of an elastic material which is deformed during assembly and insertion into the groove.
- the incisions in the two elements do not have to be at right angles to the incision edge, they can also be arranged obliquely to it. Decisive for the arrangement is the piece of furniture to be created or its design.
- a single pin per connection is provided. This extends through a hole in the carrier element and, due to its length, protrudes from this on both sides.
- the pins can be made of any material, in particular, they are made of durable plastic, metal or even wood.
- FIG. 2 shows a first embodiment variant of a carrier element
- FIG. 3 the horizontal element from FIG. 1 and the carrier element from FIG
- FIG. 6 the horizontal element from FIG. 4 and the carrier element from FIG. 5 in the assembled state
- Fig. 8 an advantageous embodiment of a pin.
- a connection system 20 has a horizontal element 22 and a carrier element 24. These can be seen in particular in Figures 1, 2, 4 and 5.
- the horizontal element 22 and the carrier element 24 will hereinafter be referred to collectively as elements 22, 24.
- the two elements 22, 24 each have a length I, a width b and a thickness or thickness d.
- the two elements 22, 24 each have a length I, a width b and a thickness or thickness d.
- d a thickness or thickness
- the horizontal element 22 has a first incision 26, which extends from a first incision edge 28 in the direction of a front edge 30.
- the carrier element 24 has a second cut 32, which extends from a second cut edge 34 in the direction of a trailing edge 36.
- the incisions 26, 32 shown are arranged at right angles to their respective incision edges 28, 34. However, this is only to be understood as an example, the cuts 26, 32 can also be aligned obliquely to the cut edges 28, 34.
- the support member 24 opposite to the second cut 32 in the region of the trailing edge 36 has two pins 38 which are opposite to each other in the opposite direction laterally from the Carrier element 24 protrude.
- two pins 38 instead of two pins 38, only a single pin 38 can be used, which is guided through a continuous bore and whose length exceeds the thickness B of the carrier element 24.
- Figure 3 shows the two elements 22, 24 in the assembled state. In the process, they are pushed into one another via their indentations 26, 32, with a depth T of the indents 26, 32 being selected such that the trailing edge 36 of the carrier element is flush with the first indentation edge 28 of the horizontal element 22.
- the two elements 22, 24 thereby form a cross connection, which is executed at right angles in the embodiment shown. However, the two elements 22, 24 can also be aligned with one another at any other angles.
- FIGS. 2 and 3 also illustrate that the pin or pins 38 are arranged in such a way that the horizontal element 22 rests on the pin or pins 38 in the assembled state of the two elements 22, 24. This results in at least two bearing surfaces for the horizontal element 22, namely on a lower recess inner surface 50 of the support member 24 and the pin 38. This causes a very stable connection of the two elements 22, 24 and causes a constructed on this basis shelf has a high load capacity.
- FIGS. 4, 5 and 6 show a particularly advantageous second embodiment variant of the invention.
- the horizontal element 22 has in its first incision edge 28 two grooves 44 which, starting from the first incision 26, extend parallel to the longitudinal extent of the horizontal element 5, 22.
- the grooves 44 terminate in the recess 26.
- a variant is also possible in which only a single groove 44 is provided which opens laterally into the recess 26.
- the support member 24 has two pins 38, which in the region of the trailing edge 36 in the alignment of the notch 32 and approximately centrally to this are arranged. It may be two individual pins 38, but preferably only a single pin 38 is used, which extends through a continuous bore in the carrier element 24.
- the pin 38 is arranged in the assembled state of the two elements 22, 24 in the two grooves 44. Also in this embodiment, the pins act as a support for the horizontal element 22. However, the connection of pin 38 and groove 44 increase the assembled state in addition to the stability of the piece of furniture or shelf.
- FIG. 7 illustrates a further improvement of the connection system 20 according to the invention. Shown is a horizontal element 22 in section in the region of the first cut 26 with inserted pin 38.
- the groove 44 can be seen, which extends from the first cut edge 28.
- the groove 44 has a lower groove inner surface 46 and an upper groove inner surface 48.
- a recess 50 in the lower groove inner surface 46 can be seen, in which the pin 38 rests.
- the pin 38 has a diameter D which exceeds a height H of the groove.
- the diameter of the pin 38 may be 5 mm, the height H of the groove 4.5 mm. This causes the pin 38 is held firmly in the groove 44 and in particular is pressed into the recess 50.
- the groove 44 has at the first incision edge 28 an insertion aid for the pin 38, which is formed by an inclined surface 52, which causes a widening of the groove 44 in the direction of its opening. When inserting the pin 38, this is guided along the inclined surface 52 in the groove 44, which facilitates the construction and the assembly of the elements 22, 24.
- the inclined surface 52 encloses an angle of about 30 ° to 60 °, preferably 45 ° with the Nutinnen- surface 46 a.
- Figure 8 shows an advantageous embodiment of a pin 38 in a side view. It can be seen that this is not exactly executed straight, but slightly bent, that has a deviation on its longitudinal axis XX.
- a Pin 38 may be made of metal, in which case the groove inner surfaces 46, 48 should be designed to be elastic. On the other hand, if the groove inner surfaces 46, 48 are rigid, the pin 38 can be made of a resilient elastic material. Theoretically, instead of the elastic embodiment, a plastic deformation of the pin 38 and / or the groove 44 is also possible.
- the invention is not limited to the embodiment described, but also includes further embodiments, which are based on the essential features of the invention.
