Description

[0001] Method for tensioning a multi-part articulated arm of an awning and articulated arm for an awning

[0002] The invention relates to a method for tensioning a multi-part articulated arm of an awning, wherein the articulated arm has a first arm member and a second arm member which are articulated to one another by means of an arm joint, wherein a spring device is connected to the first arm member and then guided along the articulated arm around or through the arm joint to the second arm member, whereupon the spring device is tensioned by means of a tensioning device and then connected to the second arm member, so that the multi-part articulated arm is pre-tensioned into an extended position by means of the spring device, wherein the spring device is connected to a holding part in its end region facing the second arm member before tensioning and wherein the tensioning device is subsequently brought into engagement with the holding part, then the holding part is subjected to a tensile force and then hooked behind at least one projection of the second arm member.

[0003] The invention also relates to an articulated arm for an awning with a first arm member and a second arm member which are articulated to one another by means of an arm joint, wherein a spring device is connected to the first arm member, is guided along the articulated arm around or through the arm joint to the second arm member and is connected in its end region facing the second arm member to a holding part which is held by the second arm member, wherein the holding part has at least one engagement section with which the holding part is hooked behind at least one projection of the second arm member. One constructive possibility for unwinding an awning fabric from a fabric shaft of the awning and winding it onto this consists in using pre-tensioned multi-section articulated arms.For example, a multi-link articulated arm is connected in an articulated manner with its first arm link to a projection rod which is fastened to an edge of the awning fabric opposite the fabric roller, and is fastened with its second arm link to a support device of the awning and held by this.

[0004] When the awning fabric is unwound from the roller shaft, the articulated arm is in the extended position, i.e., the awning fabric is taut. By rotating the roller shaft, the awning fabric can be wound onto the roller shaft against the tension of the articulated arms, whereby the arm segments of the articulated arm are folded together. By rotating the roller shaft in the opposite direction, the awning fabric is unwound, so that the arm segments of the articulated arm are unfolded again by means of the spring device, and the articulated arm is returned to its extended position.

[0005] Essential for this function is the pre-tensioned articulated arm, which is in the extended position when the awning fabric is unwound. For this to happen, the multi-section articulated arm must be pre-tensioned before being fitted to the awning, which can be done using a tensioning device. The tensioning device is attached to the spring device and the spring device is pulled along the articulated arm and is thereby pre-tensioned before being attached to the second arm section. DE 4225299 A1 discloses arranging a spring element in the form of a coil spring in the arm section facing away from the drop rod and engaging it with a projection via a tension band. A further tension band is hooked onto the opposite end of the spring element, is guided over the arm joint and hooked behind a projection in a tube stub facing the drop rod, close to the arm joint.Subsequently, a tubular housing of the first arm segment is placed on the tube stub and mounted thereon. This procedure requires numerous steps, particularly the subsequent assembly of the tubular housing of the first arm segment, and is therefore complex.

[0006] It is an object of the invention to provide a method with which the tensioning of the spring device and its attachment to one of the arm members of the articulated arm can be carried out in a simple and reliable manner.

[0007] The object is achieved according to the invention by a method according to claim 1, which is characterized in that the clamping device is introduced through an opening in the second arm member before it is brought into engagement with the holding part.

[0008] The projection projecting from the second arm member serves as a retaining element for the holding part, so that the articulated arm is held in the extended position by means of the spring device.

[0009] The spring device is preferably connected at one end to the first arm member and at another, opposite end to the holding part. The spring device can be laid along the articulated arm, i.e. along the arm members and around the arm joint or through the arm joint, whereupon the holding part is detachably connected to the tensioning device inside or outside the second arm member for tensioning. The tensioning device applies the tensile force required to tension the spring device, so that the holding part is pulled towards the end region of the second arm member. As soon as the holding part has been pulled beyond the projection, the holding part can be hooked behind the projection or fastened to it. The tensioning device is then detached from the holding part and preferably removed. The articulated arm can then be mounted on the awning.

[0010] It is provided that the clamping device is inserted through an opening in the second arm member before it is brought into engagement with the holding part. For this purpose, the holding part can already be in its initial position in the second arm member before the clamping device is inserted into the second arm member and brought into engagement with the holding part. Alternatively, it can be provided that the holding part is brought into engagement with the clamping device outside the second arm member. Optionally, the spring device can be guided both inside the first arm member and the second arm member and then connected to the holding part. By inserting the clamping device through the opening in the second arm member, the housing of the second arm member can be pre-assembled, so that the assembly step of subsequently attaching the housing to a pipe stub is omitted.In a preferred embodiment of the invention, the clamping device is inserted into the second arm member at an end opposite the arm joint. It can be provided that the retaining part is brought into engagement with the projection at an end portion of the second arm member opposite the arm joint.

[0011] According to one embodiment of the invention, a tension plate, particularly made of steel, can preferably be used as the holding part. If a tension plate is used as the holding part, the tension plate can have recesses with which it can easily engage behind the projection and / or be pulled along the ramp sections during tensioning.

[0012] In order to structurally engage the clamping device with the holding part, according to an advantageous embodiment of the invention, it can be provided that the clamping device engages, preferably releasably, in at least one tension recess in the holding part. Preferably, the same applies to the spring device, which, according to an optional embodiment of the invention, preferably releasably engages, preferably in at least one spring recess in the holding part. Both the spring device and the clamping device can engage independently of one another in recesses (spring recess, tension recess) in two opposite end regions of the holding part, for example by means of hooks.

[0013] The spring device is preferably constructed in several parts. It has at least one spring element, in particular in the form of a helical spring or a coiled spring, the spring element being connected to the outer first arm member by means of a first transmission member, for example in the form of a tension band. The first transmission member is guided through or around the arm joint and is connected to the spring element in the interior of the second arm member. On the side of the spring element opposite the first transmission member, a second transmission member, in particular in the form of a tension rod, can be provided, via which second transmission member the spring device engages with the holding part. However, the spring element can also engage directly with the holding part.

[0014] In a further development of this embodiment of the spring device, several and in particular two spring elements can also be provided. The two spring elements are preferably connected in parallel in terms of force, i.e. both spring elements engage directly or indirectly on the first transmission member or on the holding part. At their opposite end facing the holding part, both spring elements are directly or indirectly in engagement with the holding part. A corresponding holding part can be plate-shaped and, in its end facing the spring device, have two spring recesses into which the two spring elements engage, preferably independently of one another. In its opposite end region, the holding part has a tension recess for engagement with the tensioning device and, in a central region, at least one engagement section for engagement with the projection.

[0015] The two spring elements can be offset from one another in the longitudinal direction of the spring device and thus in the longitudinal direction of the second arm member, so that they are not located directly next to one another, but rather axially one behind the other with a slight offset. This has the advantage that the spring device requires little installation space perpendicular to the longitudinal extension of the spring elements.

[0016] Preferably, it can be provided that the holding part is pulled over a ramp section of the second arm member during tensioning by means of the tensioning device before the holding part is hooked behind the projection or fastened to it.

[0017] Because of the ramp section, the holding part is pulled steadily and smoothly from its starting position, in which no tensile force is yet applied to the holding part, by means of the tensioning device along the ramp section that leads to the projection. When the holding part is pulled over the ramp section, the holding part is preferably deflected transversely to the longitudinal axis of the arm member or transversely to the line of action of the tensile force. As soon as the holding part has been pulled over the projection, it falls or snaps into place behind it automatically. The projection preferably has a recess in the section that the holding part engages behind, into which recess the holding part can engage. Alternatively, the holding part can be adjusted transversely to the longitudinal axis, in particular by a corresponding movement of the tensioning device, so that the holding part does not snap into place, but is guided behind the projection in a controlled manner and set down there.It is also possible to perform a combination of the two aforementioned movements.

[0018] In order to easily pull the holding part behind the projection, according to an advantageous embodiment of the invention, the holding part can be guided along guide sections of the second arm member. Alternatively or additionally, the clamping device can be guided by means of the second arm member.

[0019] The guide sections prevent the holding part from tilting or catching on or in the second arm link during tensioning. Preferably, the holding part is adapted to the guide sections in such a way that it can be moved transversely to the second arm link with little or no play for the holding part and can only be pulled along the second arm link along the guide sections.

[0020] A tensioning process according to the method according to the invention is explained below by way of example. In this case, it can be provided that the two preferably prefabricated arm members are first arranged next to one another in a parallel position and fixed in this alignment before the spring device is tensioned. The spring device is preferably already fastened to the first arm member in a previous method step by means of the first transmission element, for example a tension band inside the first arm member and is guided over the arm joint or through the arm joint into the interior of the second arm member. There, the first transmission element engages the spring element or the spring elements, in particular in the form of one or more coil springs. A second transmission element, in particular in the form of a tension band or a tension rod, can be provided at the opposite end of the spring element or the spring elements.At the end of the first arm member facing away from the arm joint, the tensioning device with a hook part is introduced into the interior of the first arm member through the front opening and engages with the holding element which is connected to the second transmission element and / or to one or more spring elements. A tensile force is then applied by means of the tensioning device, by means of which the spring device is tensioned. As a result of the tensile force, the spring device lengthens until the holding part can be hooked behind the projections of the second arm member. The tensioning device then disengages with its hook part from the holding part and is pulled axially out of the second arm member.In this way, not only is the spring device tensioned, but the arm links, which are secured in their adjacent position, are practically ready for transport and no longer have to be folded together against the force of the spring device.

[0021] In an articulated arm according to the invention, the holding part has at least one engagement section with which the holding part is hooked behind at least one projection of the second arm member. In order to reach the holding part in the interior of the second arm member, according to an advantageous aspect of the invention it can be provided that the second arm member has an opening through which the tensioning device can be inserted into the interior of the second arm member. The holding part is accessible through the opening even after the spring device has been tensioned, it also being possible to check whether the holding part is correctly hooked behind the projection.

[0022] The projection preferably has a recess into which the holding part can engage with its engagement sections and can no longer independently leave this rear engagement. This is advantageous when movements of the articulated arm in a normal operating state exert tensile forces on the spring device and the suspended holding part.

[0023] According to one embodiment of the invention, the holding part can preferably be located in an interior space of the second arm member when suspended. By positioning the holding part in the interior space of the second arm member, the mechanism for tensioning the spring device can be arranged and concealed from outside the second arm member in a space-saving manner.

[0024] Preferably, the opening is formed at the axial end of the second arm member opposite the arm joint.

[0025] The projection can be formed on the axial end region of the second arm member opposite the arm joint in the interior of the second arm member.

[0026] In order to allow the retaining part to be suspended behind the projection, an advantageous embodiment of the invention can provide for the second arm member to have a ramp section in its interior. The ramp section has a gradient in the direction of the projection, wherein, when the spring device is tensioned, the retaining part is pulled along the ramp section to the projection and is there suspended behind the projection or automatically engages behind the projection. The ramp section enables continuous tensioning until it is suspended.

[0027] According to an advantageous embodiment of the invention, the spring device can be suspended with its end region facing the second arm member in at least one spring recess of the holding part. Preferably, the holding part can be designed as a tension plate and made of steel. The spring device can engage in at least one recess in a hook-like manner.

[0028] Optionally or alternatively, the first arm member may also have the holding part which can be hooked behind the projection by means of the pulling device.

[0029] In a further development of the invention, it can be provided that the spring device has at least two spring elements connected in parallel in terms of force, in particular in the form of helical springs, which are offset from one another in the axial direction of the second arm member and are thus arranged one behind the other.

[0030] Preferably, the holding part has a separate spring recess for each spring element.

[0031] In a further development of the invention, it can be provided that the holding part has at least one securing projection, by means of which an axial movement of the holding part in its suspended state is limited in the direction of the end of the second arm member opposite the arm joint.

[0032] An awning has a roller shaft on which an awning fabric can be wound up, and at least one multi-part articulated arm which is designed according to the invention.

[0033] The invention is explained below by way of example using schematic representations. Therein: Fig. 1 shows a perspective view of an awning with two articulated arms,

[0041] Fig. 9 a holding part according to a 2nd modification and

[0042] Fig. 10 is a side view of a spring device with two parallel spring elements and a holding part according to Fig. 9.

[0043] Figure 1 shows a schematic perspective view of an articulated-arm awning 10, which has a horizontally extending roller shaft 23 that is rotatably mounted on a support device 25, which can be a building wall, a beam, or other support. An awning fabric 24 is attached to the roller shaft 23 with an inner end facing the roller shaft 23 and can be wound onto and unwound from the roller shaft.

[0044] At the opposite end, the awning fabric 24 is connected to a horizontally extending projection rod 26. The projection rod 26 is connected to a drive device which, in the illustrated embodiment, is formed by two spring-loaded, two-part articulated arms 11. Each articulated arm 11 has an outer first arm member 11a and an inner second arm member 11b. The outer first arm member 11a is connected to the projection rod 26 at its end facing the projection rod 26 via a joint device 27a. The inner second arm member 11b is connected in an articulated manner, directly or indirectly, to the support device 25 at its inner end facing the fabric shaft 23 by means of a joint device 27b. At its opposite end, the second arm member 11b is articulated to the first arm member 11a via an arm joint 12. Each articulated arm 11 is supported by a spring device 13 (see Fig. 1) not shown in Fig.2 ) in a known manner into its extended position, i.e. pre-tensioned into a position in which the awning fabric 24 is stretched as far as possible.

[0045] Figure 2 shows a perspective sectional view of an end region of the second arm member 11b according to Figure 1, wherein only an end region of the second arm member 11b facing the cloth shaft 23 is shown. Alternatively or optionally, the following also applies to the first arm member 11a, which is held in an end region facing the drop-out rod 26. The second arm member 11b has in its end region the joint device 27b, with which it is pivotally mounted and held on the support device 25. The joint device 27b is inserted into a tubular housing 28 of the second arm member 11b, connected to it via a fit and has in an area facing the interior 22 of the housing 28 guide sections 17, which open into ramp sections 16 in a direction facing away from the interior 22. The ramp sections 16 have a gradient and end at two projections 15 .

[0046] Located in the interior 22 of the housing 28 is the spring device 13, which engages with a hook 30 in a spring recess 20 of a plate-shaped holding part 14. The holding part 14 in the interior 22 of the housing 28 is hooked behind the two projections 15 of the joint device 27 by two engagement sections 21. The holding part 14 can be reached from the outside by a user through an opening 18 formed in the axial end region of the second arm member 11b in the joint device 27 for attaching a tensioning device 40, which can be brought into engagement with a pulling recess 19 of the holding part 14 and which can pull the holding part 14 by means of a pulling force F in the direction of the opening 18 and hook it behind the projections 15. Only one hook part 41 of the clamping device is shown as an example in Figure 2.

[0047] Figure 3 shows a side view of the holding part 14 according to Figure 2, which is plate-shaped and has the spring recess 20 in a region facing the spring device 13, which is on the left according to Figure 3, into which spring recess the spring device 13 can engage like a hook. In an opposite end region, the holding part 14 has the pulling recess 19, which can be brought into engagement with the hook part 41 of the tensioning device 40. The two end regions are connected by means of a central section 29, which tapers in the direction of the pulling recess 19 by means of cutouts to the engagement sections 21, with which the holding part 14 can engage behind the projections 15.

[0048] In its left-hand end region according to Figure 3, which, when the holding part 14 is in the suspended state, is arranged on the side of the projections 15 facing away from the opening 18, two securing projections 35 are formed on the holding part 14. These securing projections 35 serve to prevent the holding part 14 from emerging from the second arm member 11b through the opening 18 if the spring device 20 tears or breaks and the holding part 14 is then subjected to a force directed in the direction of the opening 18 as a result of the spring tension still present. In this case, the securing projections 35 bear against the inner end faces of the ramp sections 16, as a result of which the movement of the holding section 14 is stopped.

[0049] Figures 4 to 6 show sectional views of the second arm member 11b in different phases and at different times of the method according to the invention, wherein all three figures show the tubular housing 28 into which the joint device 27 is inserted and to which it is connected. In its interior space 22, the housing 28 has the plate-like holding part 14, by means of which the spring device 13 is tensioned and which has the spring recess 20 and the tension recess 19.

[0050] The joint device 27 has, in a section that abuts an inner wall 31 of the interior 22 of the housing 28, a projection 15 projecting toward the center of the interior 22, behind which the holding part 14 is hooked. So that the holding part 14 engages behind the projection 15, the projection 15 has an undercut 33, behind which the holding part 14 can be hooked with its engagement sections 21.

[0051] Figure 4 shows the holding part 14 in its initial position in its non-suspended state in the interior 22 of the housing 28. Through the front opening 18 of the joint device 27, the tensioning device 40 shown in Figure 2 can be inserted into the interior 22 of the housing 28 and brought into hook-like engagement with the holding part 14 at the tension recess 19.

[0052] When the tensioning device 40 is engaged with the holding part 14, it can exert a tensile force F on the holding part 14 in the direction of the opening 18 or the projections 15 and thus pull the holding part 14 over the ramp sections 16 to the projections 15, as shown in Figure 5. With the displacement of the holding part 14, the spring device 13 is tensioned, which, according to Figures 5 and 6, engages in the spring recess 20 of the holding part 14 by means of the hook 30.

[0053] According to Figure 6, the holding part 14 is suspended and the spring device 13 is tensioned. The tensioning device 40 is retracted through the opening 18. In this state, the holding part 14 engages with its engagement sections 21 in the undercuts 33 of the two projections 15, between which the holding part 14 is suspended. Due to its tension, the spring device 13 causes the holding part 14 to remain suspended behind the projections 15. Figure 7 shows a holding part 14 according to an alternative embodiment, wherein the holding part 14 has a single recess 34 in the center, which serves both as the spring recess 20 and as the engagement section 21. In one of the individual recesses 34, which is offset from the right end region according to Figure 7, the holding part 14 has two recesses which serve as pulling recesses 19 on which the clamping device 40 can engage.

[0054] Figure 8 shows a perspective sectional view of the end region of the second arm member 11b with the holding part 14 according to Figure 7. The second arm member 11b also has the tubular housing 28 and the joint device 27, which is inserted into the housing 28 and which is connected to the housing 28 by means of a fit.

[0055] The joint device 27 has a single projection 15 on a wall section 32, which projects in the direction of an interior space 22 of the housing 28. The holding part 14 according to Figure 7 is suspended with its engagement section 21 behind the projection 15, wherein the spring device 13 engages with a pull rod in the interior space 22 of the housing 28 in a hook-like manner in the spring recess 20 of the holding part 14, which is formed with the engagement section 21 in the common recess 34.

[0056] In order to tension the spring device 13, the joint device 27 has an end opening 18 through which a tensioning device of the type mentioned (not shown in Figure 8) can be introduced into the interior 22 of the housing 28 and the joint device 27 for tensioning. During tensioning, the tensioning device can be brought into engagement with the tension recesses 19 of the holding part 14, so that the tensioning device can tension the spring device 13 and suspend the holding part 14 behind the projection 15 by means of its engagement section 21.

[0057] The spring device 13 is preferably constructed in several parts. It has at least one spring element, in particular in the form of a helical spring or a coiled spring, wherein the spring element is connected to the outer first arm member 11a by means of a first transmission member, for example in the form of a tension band. The first transmission member is guided through or around the arm joint 12 and is connected to the spring element in the interior 22 of the second arm member 11b. On the side of the spring element opposite the first transmission member, a second transmission member can be provided, in particular in the form of the tension rod already shown, via which the spring device engages the holding part 14.

[0058] In a further development of this embodiment of the spring device 13, several and in particular two spring elements 13a and 13b can be provided, as shown in Figure 10. The two spring elements 13a and 13b are connected in parallel in terms of force, i.e. both spring elements 13a and 13b engage directly or indirectly with the first transmission element. At their opposite end facing the holding part 14, both spring elements 13a and 13b are directly or indirectly in engagement with the holding part 14. A corresponding holding part 14 is shown in Figure 9. It is plate-shaped and has two spring recesses 20a and 20b in its end facing the spring device 13, which is the left end according to Figure 9, into which the two spring elements 13a and 13b engage independently of one another.

[0059] In its opposite end region, which is on the right according to Figure 9, the holding part 14 has the already explained pulling recess 19 and in a central region the already explained engagement sections 21.

[0060] As can be seen from Figure 10, the two spring elements 13a, 13b are arranged offset from one another in the longitudinal direction of the spring device and thus in the longitudinal direction of the second arm member such that they are not located directly adjacent to one another, but rather axially one behind the other with a slight offset. This has the advantage that the spring device 13 requires little installation space perpendicular to the longitudinal extension of the spring elements 13a and 13b.
