Description

P34512NLO0/IWO Title: Mechanical connection assembly The present invention is related to a mechanical connection assembly for connecting tubular elements. A method of connection multiple tubular elements together is to weld them together. However, welding deteriorates properties, such as yield strength of the tubular elements. Therefore a mechanical connection system is preferred.
Known mechanical tubular elements connection systems comprise a connector assembly that is adapted to connect tubular elements. A known system of the applicant comprises a connector assembly that is adapted to connect a first tubular element and a second tubular element. The system comprises a first half adapted to be inserted into the tubular and a second half adapted to be inserted into the second tubular. A moveable gripping element is provided that grips a tubular element. These systems are conventionally applied in building frames or structures, e.g. comprising hollow vertical tubular elements. Other applications include other structures from tubular elements, such as truck beds or trailers, or utility pole assemblies for lightning. The aim of the present invention is to provide an improved tubular elements connection assembly that provides a reliable and stable connection to a tubular element.
This aim is accomplished by the mechanical connection assembly of claim 1. The mechanical connection assembly is suitable for connecting tubular elements. The tubular elements may be for example hollow tubular elements. The connection assembly is adapted to be connected to a tubular elements in a connection direction. The connection direction is the relative direction wherein the connection assembly and the tubular element are connected to each other. The connection assembly comprises a connection body and a gripping element that is provided in the connection body. The connection body preferably has a similar appearance, for example in colour or material used, as the tubular elements to which it connects. The connection body comprises a first portion, which is adapted to be inserted into the tubular element in the connection direction. Thus when the connection body is connected to the tubular element the first portion may be hidden from view by the tubular element. In embodiments the first portion is be provided with a surface that increases friction between the first portion and the tubular element to increase sturdiness of the connection between the tubular element and the first portion. For example, the first portion is coated to increase friction. In another example, the first portion is provided with a profile to increase friction. The connection body further comprises a second portion which is adjacent to the first portion of the connection body and which is located parallel to the connection direction relative to the first portion. In embodiments the second portion has a similar contour and cross section as the tubular element to which the connection body connects. Thus, when the connection body and tubular element are connected, there may be a smooth transition between the tubular element and the connection body on the outsides thereof.
The connection body comprises a first opening, for example an elongated first opening, in the first portion and a second opening, for example a round second opening, in the second portion. The first opening and the second opening are connected by a passage which is located inside the connection body. The passage extends between the first opening and the second opening. The passage has a sliding surface below the first opening that is inclined relative to the connection direction and which makes a sharp angle with the connection direction relative to the second portion. The gripping element comprises a gripping portion which is adapted to grip the tubular element. The gripping element may be a leaf spring. The gripping element further comprises a sliding portion that is adapted to slide along the sliding surface of the passage. The gripping portion may be a portion of the gripping element which is inclined relative to the sliding portion of the gripping element. The gripping element further comprises a pressing portion where a pressing force may be applied to the gripping element.
The gripping element is moveably provided in the passage of the connection body. The pressing portion is located below the second opening. The sliding portion is provided adjacent to the sliding surface of the passage such that the gripping element may slide along the sliding surface of the passage.
The mechanical connection assembly of the invention comprises a non-connected configuration, wherein a tubular element may be mounted or dismounted from the connection body, and a connected configuration, wherein a tubular element is be fastened to the connection body. In the connected configuration a pressing force is applied on the pressing portion of the gripping element. For example a pressing force is applied by a pressing element that is provided in the second opening. The gripping element is pressed into a gripping position by the pressing force. In the gripping position the gripping element is supported by the sliding surface such that the gripping portion extends out of the contour of the first portion of the connection body. In this gripping position the gripping portion provides a gripping force on a tubular element wherein the first portion is inserted. The gripping force is directed parallel to the sliding surface of the passage. The gripping force has - a pressing force component that acts on the tubular element which is directed perpendicular to the connection direction. The pressing force component results in a gripping connection between the connection body and the tubular element, and - a pulling force component which is directed parallel to the connection direction. The pulling force component results in a pulling connection between the connection body and the tubular element.
Thus in the connected configuration the gripping element provides a gripping force on the tubular element. The gripping force provides both a gripping connection between the connection body and the tubular and a pulling force between the connection body and the tubular. The connection body is thus forced into a connection with the tubular element by providing the pressing force.
In the non-connected configuration, the gripping element is in a mounting position thereof. In the mounting position the gripping portion does not extend out of the contour of the first portion. Thus in the non-connected configuration the gripping portion does not provide a gripping force to the tubular element and the first portion may be inserted into or removed from tubular element.
Because the connection between the tubular element and the connection body is not achieved by a lever construction but rather with a sliding construction, the gripping element provides both a pulling force and a pressing force. The relative magnitude of these force components may be determined by the inclination of the sliding surface relative to the connection direction. For example, a relatively steeper surface may result in a relatively stronger pressing force and a relatively weaker pulling force.
In an embodiment, a pressing element is moveably provided in the second opening of the connection body, wherein, in the connected configuration, the pressing element is in a pressing position wherein the pressing element provides the pressing force on the pressing portion of the gripping element and wherein, in the non-connected configuration, the pressing element is in a non-pressing position, in which non-pressing position the pressing element allows the gripping element to be in the mounting position thereof.
In embodiments the pressing element is a screw, for example an adjusting screw, which is threadingly provided in the second opening.
The screw may be moved in the pressing position by a tool such as a screwdriver but it may also be possible that the screw can be manually turned such that no additional tools are necessary.
In other embodiments the pressing element may be a button element which may be pressed into the pressing position.
For example, the button element may have a clicking mechanism to secure the button in the pressing position.
In embodiments the connection assembly is adapted to be connected to a second tubular element in a second connection direction, wherein the second connection direction is not parallel, for example perpendicular, to the first connection direction.
In this embodiment the connection assembly allows the connection of tubular elements that are not parallel to each other.
For example, in this embodiment the connection body is a corner joint.
In embodiments the second portion comprises an inner corner, and wherein the second opening is provided adjacent to the inner corner.
In these embodiments the second opening is provided such that it is less visible when the connection assembly is connected with the tubular elements.
In embodiments, the connection body comprises a third portion, wherein the connection body further comprises a third opening in the second portion and a fourth opening in the third portion, wherein the third opening and fourth opening are connected by a second passage that is located in the connection body, wherein a second gripping element is provided in the second passage for gripping the second tubular element, the second gripping element comprises a sliding portion which is located adjacent to a sliding surface of the second passage.
In embodiment a second gripping construction is provided similar to construction present in the first and second portions.
The second gripping element provides a gripping force on a second tubular which gripping force has a pressing force component and a pulling force component.
The pressing force component acts on the second tubular element and is directed perpendicular to the second connection direction and the pulling force component acts on the second tubular element and is directed parallel to the second connection direction. Thus in this embodiment the connection assembly may be corner join that connects two tubular elements in a corner. Preferably the second opening and third opening are 5 provided adjacent to an inner corner of the second portion of the connection body. In an embodiment the connection body further comprises a wire passage that allows wiring to extend from the tubular element through the connection body.
Embodiments of the invention will now be described with reference to the appended figures. Therein, Figure 1 schematically depicts a first embodiment of a mechanical connection assembly according to the invention; Figure 2 depicts a cross section of the mechanical connection assembly of figure 1 in the non-connected configuration; Figure 3 depicts a cross section of the mechanical connection assembly of figure 1 in the connected configuration; Figure 4 depicts a cross section of the mechanical connection assembly of figure 1 connected to a tubular element; Figure 5 schematically depicts a second embodiment of the mechanical connection assembly according to the invention; Figure 6 depicts a cross section of the second embodiment of the mechanical connection assembly connected to a tubular element; Figure 7 depicts the mechanical connection assembly of figure 5 in the connected configuration; and Figure 8 depicts a mechanical connection assembly of the second embodiment connected to a tubular element.
Figure 1 schematically depicts a first embodiment of a mechanical connection assembly 1 according to the invention. The connection assembly 1 is adapted to be connected to a tubular element (not shown) wherein the figure shows part of the connection body 3. The connection assembly 1 is adapted to be connected to a tubular element 2 in the connection direction R1.
The connection body 3 comprises a first portion 5 and a second portion 6. The first portion 5 is adapted to be inserted into the tubular element. The first portion comprises a profile to increase friction resistance between the first portion 5 and the tubular element when the first portion 5 is inserted in the tubular element. The first portion 5 of the figure has a square contour which is slightly smaller than the square contour of the second portion 6.
A first opening 7 is provided in the first portion 5. The first opening in the figure is an elongated rectangle that allows a gripping element 4 to move in the connection direction while restricting movement of the gripping element 4 in a direction perpendicular to the connection direction R1.
The second opening 8 is provided in the second portion 6. The second portion 6 is located adjacent to the first portion 5 and is located parallel to the connection direction relative to the first portion 5. A pressing element 14 in the form of a screw is provided in the second opening 8 to provide a pressing force to the gripping element 4.
As can be seen from the figure the gripping element 4 is provided in the connection body 3. The gripping element comprises a gripping portion 11 and a sliding portion 12 which is located adjacent to a sliding surface. The gripping portion 11 is, in this embodiment, a piece of the gripping element which makes an angle with the sliding portion 12.
The connection boy 3 is further provided with a wire passage 21 that allows wires, such as electricity cables, to extend through a tubular element into the connection body 3 and preferably leave the connection body 3 through a second tubular element. This allows the wires to be hidden and increases aesthetics.
Figure 2 depicts a cross section of the mechanical connection assembly 1 of figure 1 in the non-connected configuration. As can be seen from the figure a passage 9 extends between the first portion 5 and the second portion 6 of the connection body 3. The gripping element 4 is provided inside the passage 9.
The passage 9 connects the first opening 7 and the second opening 8. In the second opening 8 a pressing element 14 is provided which may press against the pressing portion 13 of the gripping element 4. The pressing element 14 in the figure is in the non-pressing position wherein it does not press against the pressing portion 14 of the gripping element 4.
The passage 9 has a sliding surface 10 which is inclined relative to the connection direction. As can be seen from the figure the sliding portion 12 of the gripping element 4 is located adjacent to the sliding surface 10.
The gripping element 4 is not being pressed by the pressing element 14 which allows the gripping element 4 to be located in the mounting position. As can be seen from the figure in the mounting position the gripping portion 11 does not extend from the contour of the first portion 5. This allows a tubular element 2 to be slid over the first portion 5 without the tubular element 2 interacting with the gripping element 2. The gripping element 2 is allowed to not extend from the contour because it allowed to be recessed into the first portion 5. In this position, the gripping element 4 is slid down the sliding surface 10 of the passage 9. Figure 3 depicts a cross section of the mechanical connection assembly 1 of figure 1 in the connected configuration. In this configuration a pressing force is applied on the pressing portion 13 of the gripping element 4 by the pressing element 14. The gripping element 4 is pressed into the gripping position by this force. As can be seen from the figure the gripping element 4 is slid up the sliding surface 10 which allows the gripping portion 11 to extend out of the first opening 7 and from the contour of the first portion 5.
In the gripping position the gripping portion 11 provides a gripping force on the tubular element 2. The gripping force F is directed parallel to the sliding surface 10 of the passage 9, and the gripping force has - a pressing force component F1 that acts on the tubular element 2 which is directed perpendicular to the connection direction, which pressing force component results in a gripping connection between the connection body 3 and the tubular element 2, and - a pulling force component F2 which is directed parallel to the connection direction, which pulling force component results in a pulling connection between the connection body 3 and the tubular element 2.
Figure 4 depicts a cross section of the mechanical connection assembly 1 of figure 1 connected to a tubular element 2. As can be seen from the figure the pressing element 14 is not in the pressing position thereof. Thus the tubular element 2 is not being gripped by the gripping element 4 and the gripping portion 11 does not provide the gripping force on the tubular element 2. This allows the tubular element to be removed from the connection assembly.
For example, the tubular element 2 has just been placed in this position by inserting the first portion 5 inside the tubular element 2. The next step in connecting the tubular element 2 to the connection assembly would be to screw the screw 14 into the second opening 8 such that it provides a pressing force on the gripping element 4. The gripping element 4 then provides a gripping force on the tubular securely connecting the tubular element 2 to the connection assembly 1. The gripping force pulls the tubular element 2 towards the second portion 6 by the pulling force component thereof. Thus the tubular element 2 is not only connected to the connection assembly 1 it is also forced into position.
Figure 5 schematically depicts a second embodiment of the mechanical connection assembly 1 according to the invention. In this embodiment the connection assembly 1 is adapted to be connected to a second tubular element 2 in a second connection direction. The second connection direction is perpendicular to the first connection direction.
The second portion 8 of the connection body 3 comprises an inner corner. The second portion comprises the second opening 8 and the third opening 17 which are both located adjacent to the inner corner. This allows for aesthetic constructions using the connection assembly because the pressing elements 14 are more hidden from view compared to other embodiments.
The connection body 3 further comprises a third portion 16 which is adapted to be inserted in a tubular element. The third portion 16 comprises a fourth opening 18 which is connected to the third opening 16 by a second passage 19. A second gripping element 20 is provided in the second passage 19. Similarly to the gripping element 4, the second gripping element 20 allows the connection assembly 1 to be connected to a second tubular element 2 by a gripping force. The gripping force of the second gripping element 20 is parallel to the sliding surface 22 of the second passage 20.
Figure 6 depicts a cross section of the second embodiment of the mechanical connection assembly 1 connected to a tubular element 2. As can be seen from the figure the pressing element 14 is not in the pressing position. This the connection assembly 1 may be in a similar configuration as the connection assembly 1 depicted in figure 4.
As can be seen from the figure a wire passage 21 allows wires to extend through the connection body 3 from the first portion 5 to the third portion 16.
Figure 7 depicts the mechanical connection assembly 1 of figure 5 in the connected configuration.
As can be seen from the figure the pressing element 14 is pressed into the second opening 8 and the gripping portion 11 extends from the contour of the first portion 5. The second gripping element 20 is also in a connected configuration thereof.
In this configuration the second gripping element 20 extends from the contour of the third portion 16 of the connection body 3. Thus the second gripping element 20 may provide a gripping force to a second tubular 2 when the third portion 16 is provided into the second tubular element 2. Figure 8 depicts a mechanical connection assembly of the second embodiment connected to a tubular element 2. In this figure components provided on the inside of the connection assembly 1 are shown with dashed lines.
In this figure the first gripping element is not being pressed by the pressing element 14 thus the tubular 2 does not experience a gripping force.
Other embodiments of the invention, for example wherein the first connection direction and second connection direction are not perpendicular or that allow for more than two tubular elements to be connected, are possible.
This embodiments may be constructed in a straight forward manner by the person skilled in the art.
