Tent frame and hinge for this
The present invention relates to a tent frame provided with foldable uprights formed of preferably resiliently flexible upright sections interconnected by lockable hinges, which hinges include a first and second hinge members each with the associated upright section and by a hinge. pins are interconnected, and further provided with a locking device which is provided with a first locking member slidably connected to the first hinge part connected in the direction of a locking position, and a second locking member formed on the second hinge part, with which the first locking member the meshing engages in a desired mutual angular position of the post sections.
Such a tent frame is known, for example, from US patent 4,750,509. This patent shows a dome tent which is provided with a tent frame which has no loose parts and can be easily set up by pulling up a central ridge element to which the posts are hingedly attached. The hinge locking device in the foldable posts comprises a sliding sleeve as a first locking member and an extension on a hinge sleeve as a second locking member. To lock each hinge, the sliding sleeve must be pushed away from the extension against the action of a spring, after which the post sections can be brought into line with each other and by sliding the sliding sleeve over the extension then a locking of the style sections take place.
The invention now aims to provide a tent frame of the type mentioned in the preamble, which, with a simpler construction, enables a more reliable operation and an even easier setting up of the tent.
For this purpose, the tent frame according to the invention is characterized in that the first locking member is a locking pin accommodated in the first hinge part and the second locking member is a locking cavity formed in the second hinge part in which the locking pin engages in its locking position.
Due to the internal mounting of the locking pin and the locking cavity in the hinge parts, there is considerably less chance that the locking device cannot come into the locked position due to an external cause or is simply moved out of the locking position by an external force and thus the stability of the tent endanger. Furthermore, the construction according to the invention makes it possible in a simple manner for the locking device to act automatically by bringing the post sections into the desired angular position, for instance by stretching the posts, so that it is no longer necessary to hinge all the joints by separate operations to lock. A possible embodiment of this is that in which the second hinge part on the side facing the first hinge part is provided with a run-up surface extending from the cavity in the hinge direction against which the spring-loaded locking pin rests in the unlocked position of the hinge. In this embodiment, when the pillar sections are pivoted to the set up position, the locking pin will move along the leading-up surface to the locking cavity and will be automatically moved into the locking cavity by the spring load. In this way, the tent can be set up in a directly locked position with one movement.
According to the invention it is advantageous if the first and second hinge parts are formed identically to reduce the number of parts and thus simplify the tent frame.
In order to further increase the stability of the tent frame in the erected position of the tent, it is advantageous if the uprights are connected at their upper ends by further hinges to a central ridge element and these hinges are equipped with a further locking device connecting the uprights of the ridge element in the erected position of the tent.
Due to this locking between the central ridge element and the posts, it is no longer possible that an external force on the tent causes it to lie flat because the posts and the central ridge element start to pivot relative to each other.
Furthermore, according to the invention it is advantageous if the posts are connected at their lower end to a corner element which can be fixed to a ground sheet of the tent, which allows an adjustment of the bottom end of the associated post in inward and outward direction.
This adjustable connection between the posts and the associated corner elements makes it possible to bring the tent fabric into a well-tensioned condition, even if the resiliently flexible posts put too much or too little tension on the fabric and also if the posts have the central cam element are locked and therefore this connection cannot exert any tension on the tent fabric.
The invention also comprises the hinge for use in the tent frame described above and the tent which is provided with the tent frame described above.
The invention will be explained in more detail below with reference to the drawings, which show an exemplary embodiment of the invention.

Fig. 9 shows detail IX of FIG.
Fig. 10 is a sectional view corresponding to FIG. 3 of an improved embodiment of the hinge of FIG. 3.
The drawings and initially Figs. 1 and 2 show a tent which is built up of an external tent fabric 1, an inner tent fabric 3 connected to it by distance members 2 and a tent frame 4 which, in the erected state, keeps the tent fabrics 1 and 3 in the desired position. . As shown in fig. 1, in this embodiment the tent frame 4 consists of four posts 5 which are connected at their upper end to a central ridge element 6 and at their lower end to a corner element 7 which in turn is connected via a corner connection 8 is connected to the inner tent fabric 3 provided with a ground cloth 9. It is of course possible to give the tent cloths 1 and 3 a completely different shape and thus also make the tent frame 4 different. For example, the tent cloths 1 and 3 can have a rectangular instead of square basic shape and the basic shape can also have a triangular or polygonal or round basic shape. The number of styles 5 may vary therewith. The material of the tent cloths 1 and 3 can also be chosen arbitrarily, although in this embodiment preference is given to lightweight tent cloths of, for example, cotton or nylon or another synthetic fiber.
As can be seen further in Figures 1 and 2, each post 5 is formed from a number, in this case three, post sections 10 which have a resiliently flexible lightweight construction and can thereby assume a curved shape and thus a tension on the tent cloths 1 and 3 can act to keep the tent cloths 1 and 3 taut. Adjacent stile sections 10 within a stile 5 are interconnected by a hinge 11 which allows the stiles 5 to be folded, such as with dashed-dotted lines in the center of Fig. 2 is illustrated. In addition, adjacent hinges 11 are mounted in opposite hinges, so that the posts 5 can be folded in a zigzag shape. The connection between the upper ends of the posts 5 and the central ridge element 6 is also made with a hinge 12, so that hinge movement is also possible here when the tent frame 4 is folded up. In principle, all parts of the tent frame 4 remain connected to each other when the tent is folded, so that no parts can be lost and the setting up of the tent is also very simple, especially when the tent cloths 1 and 3 are at least partly connected to the tent frame 4. stay. In principle, to set up the tent, it is only necessary to pull up the central ridge element 6 with the aid of an eye 13 attached to it, after the jambs 5 have been unfolded slightly, for example by means of a jerky movement, whereby the tent frame is moved to its erected position. forced. Since, according to the invention, the hinges 11 and 12 are provided with automatic locking devices, the tent frame 4 is then immediately locked in its erected position, so that it is then only necessary to anchor the corner elements 7 to the ground with the aid of ground pins 14.
3-5 show an embodiment of the hinge 11, which is provided with a locking device 15. The hinge 11 in this case consists of a first hinge part 16 and a second hinge part 17, it being clearly seen that these hinge parts 16 and 17 are identically shaped, which greatly reduces the number of different parts of the tent frame 4. The first and second hinge parts 16 and 17 are mutually connected by a hinge pin 18 which is arranged eccentrically in an extension 19 and only allows a hinge movement of the hinge parts 16 and 17 from the locked position in one hinge direction. The hinge pin 18 is arranged in a halved portion 20 of the hinge parts 16 and 17, whereby the equally shaped hinge parts 16, 17 fit tightly together. Each hinge part 16, 17 is provided with a bore 21 for receiving the associated post section 10, which in this case is fixed in the associated hinge section 16, 17 by means of a post section end section 22, respectively. 23. The bore 21 of each hinge part 16, 17 is stepped with a first section 24 of smaller diameter at the end at the post section 10 and a second section 25 of larger diameter at the end facing the other hinge part 17, 16. Furthermore, the second part 25 of the bore 21 is also provided with a key slot over a part of its length from the end facing the other hinge part 17, 16. The post section end portion 23 for the second hinge portion 17 also has a stepped design with a thinner portion 27 that fits into the first bore portion 24 and a thicker portion 28 that fits into the second portion 25 but is shorter for leaving a certain length of the second part 25. A key 29 formed on the end part 23 fits into the key slot 26 in the second part 25 of the bore 21 of the second hinge part 17. The post section end part 23 is in turn provided with a longitudinal bore 30 which is thinner portion 27 of the end portion 23 is open and closed at the opposite end, so as to fit the respective post section 10 appropriately into the longitudinal bore 30. The closed end wall of the end portion 23 is provided with a transverse rib positioning member 30 'which fits into a positioning section of the post section 10 in the form of a transverse slot 10'. For mounting the post section 10 to the associated second hinge section 17, the end section 23 is inserted from the second section 25 of the larger diameter bore 21 and the post section 10 from the opposite end, the post section 10 preferably being glued to the end section while the end part 23 is also glued in the second hinge part 17. Through the positioners 30 'and 10' and through the key 29 and key slot 26, the post section 10 is always positioned circumferentially relative to the second hinge portion 17 in a predetermined angular position, whereby hinge portions at opposite ends of each post section 10 are also in the desired angular position is positioned. In the case shown, the post section 10 can be mounted in two angled positions rotated through 180 °, whereby the hinges 11 can be attached alternately for zig-folding of the posts 5.
The post section end portion 22 which cooperates with the first hinge section 16 is longer than the post section section 23 and is slidably mounted in the first hinge section 16 to function as a locking device 15 of the hinge 11. To this end, the end of the end part 22 facing the second hinge part 17 is designed as a locking pin 31 which is movable between a locking position, as shown in Fig. 3, the locking pin 31 being located in the part of the bore 21 of the hinge parts 16 17 which is formed by the halved portions 20 of both hinge members 16 and 17, and an unlocked position in which the locking pin 31 is retracted into the first hinge member 16. The unlocked position of the locking pin 31 is determined by the end of the key slot 26 against which the key 29 abuts the post section 22. The opposite locking position is limited by protrusions 32 at the end of the end portion 22 remote from the locking pin 31. A helical compression spring 33 arranged around the end portion 22 loads the locking pin 31 in the direction of the locking position, the spring 33 being enclosed between a shoulder on the one hand which is formed by the transition between the first and second bore portion 24, 25 of the first hinge part 16 and on the other hand a shoulder formed by the transition between the thinner part 27 and the locking pin 31 of the end part 22. In order to assemble the end part 22 in the first hinge section 16, the end of the end section 22 at the projections 32 is formed with inwardly bending legs 34 which define the longitudinal bore 30 for receiving the post section 10 at that end. These legs 34 can be bent inwardly so far that the protrusions 32 are within the diameter of the first bore portion 24. In this way it is possible to mount the end part 22 in the first hinge part 16 by inserting this end part from the end of the bore 21 adjacent to the larger second bore part 25 without the post section 10 being in the longitudinal bore 30 of the end part 22 located. As a result, it is possible for the legs 34 to bend inwardly and this end of the end part 22 with the protrusions 32 to be passed through the entire bore 21. After passing the first bore portion 24 through the protrusions 32, the legs 34 spring out again. Subsequently, when the post section 10 is glued or otherwise secured in the longitudinal bore 30 of the end part 22, the legs 34 can no longer bend inwards and the end part 22 is fitted in the first hinge part 16 in an inseparable manner. During this mounting, the coil spring 33 is also brought around the end part 22 and within the first hinge part 16. The locking pin 31 and with it the locking device 15 can now be unlocked by pulling the post section 10 as far as the stop of the locking pin 31 from the first hinge part 16, the locking pin 31 moving out of the locking cavity formed by the bore 21 of the second hinge part 17 and the hinge parts 16 and 17 can be rotated relative to each other about the hinge pin 18. Thereby the locking pin 31 rests with its free end against the run-up surface 35 which is formed on the extension 19 of the second hinge part 17 and extends from the bore 21 extends in the hinge direction. This run-on surface 35 is adjacent to the bore 21 at a greater distance from the hinge pin 18 than further away therefrom, whereby the hinge 11 remains in the unfolded position and not by the spring force of the coil spring 33 on the locking pin 31 to the extended position. is forced. This makes the tent frame 4 stable in the folded state. On the other hand, the run-on surface 35 ensures that the locking pin, when the hinge 11 is turned to the extended position, is automatically brought to the bore 21 acting as the locking cavity and is also automatically pushed into the locking cavity by the spring 33, so that the extended position of the hinge and therefore in the extended position of the post 5 an automatic locking takes place and therefore no separate locking operations are required when setting up the tent. In addition, the hinge 11 is very simple with only five parts, two of which are identical. Most parts can be injection molded from plastic.
It can be seen in Figs. 3 and 4 that a hinge 36 is formed on the hinge parts 16 and 17, which is intended for hooking a loop 37 (see Fig. 2) of the tent cloth 1. In order to attach the tent cloth at least at the location of the hinges 11 to be connected to the tent frame 4. Of course, the tent cloth 1 can also be connected to the posts in other places, while it is even possible to design the tent frame 4 and the external tent cloth 1 in such a way that the tent frame 4 must be placed within the external tent cloth 1.
Figures 6 and 7 show in detail the central cam element 6 with the pivotally connected stiles 5. This connection is effected via the hinges 12 which are formed with the previously described first hinge part 16 with the locking device 15. As a result, a a large number of parts are used which are also used for the hinges 11. These parts can be recognized in fig. 6 and 7. The locking cavity is formed in the central cam element 6 by a half bore 38 which, in the locking position of the hinges 12, together with the half bore 21 of the first hinge part 16 forms a bore into which the locking pin 31 can insert. Fig. 6 clearly shows the operation of the ramp surface 35, which in this case is formed on the central cam element 6 instead of on the second hinge part 17. It is furthermore noted that the posts 5 do not need an angle of 90 ° with each other while in the locking position the posts 5 need not connect horizontally to the central cam element 6 either. The choice depends on the design of the tent.
Fig. 8 shows an alternative embodiment of a hinge 11 between two jamb sections 10, in which the jamb sections in the locking position are not aligned, but form an angle α deviating from 180 °. The first hinge part 16 with the post section end part 22 and the locking pin 31 can again be retained, but the second hinge part 17 is in this case a special part that deviates from the first hinge part 16. Because the second hinge part 17 has a different design, the post section 10 is glued directly into a bore 39 of the second hinge part 17, again positioning members 30 'and 10' being provided. A half bore 40 in the second hinge part again forms the locking cavity for the locking pin 31.
Fig. 9 shows in detail the corner element 7 with a toothing 41 for forming a number of support cavities 42 in which a hinge pin 18 of the hinge part 17 can engage at the lower end of the corresponding post 5 for positioning this lower end of the post 5.
The displacement of the lower end of the post 5 allows the arc shape of the posts to be slightly changed while the corner elements 7 remain in place and therefore the groundsheet 9 remains equally flat and unloaded in all positions. With the displacement of the lower end of the posts 5, the tension on the tent fabric 1 can be changed, so that in all weather conditions (wet, dry, etc.) a nicely stretched tent fabric 1 can be achieved, as well as being sagged or too tightly stretched. will be prevented.
Fig. 10 shows an even further improved embodiment of the hinge of fig. 3. One of the improvements relates to the extension of the locking pin 31 such that in the locking position it extends not only through the first hinge part 16 and through the halved parts 20 of the hinge parts 16 and 17, but also protrudes into the second part 25 of the bore 21 of the second hinge part 17. A rigid locking between the hinge parts 16 and 17 is hereby also achieved in a lateral direction of the hinge. To lock the locking pin 31 in the locking position in addition to the coil spring 33, the locking pin 31 on the side remote from the hinge pin 18 is provided with at least one projection 41, which fits into a groove 42 in the inner wall of the second part 25 of the bore 21 in the second hinge part 17. The engagement of the protrusion 41 in the groove 42 ensures that the protrusion 41 becomes extra firmly in the groove 42 when the hinge around the hinge pin 18, for example in heavy wind, is extra strong. and the locking pin 31 is prevented from being pressed against the spring pressure of the coil spring 33 from the second hinge part 17. A second groove 43 provides a second securing should the projection 41 nevertheless shoot out of the groove 42.
It can further be seen in Fig. 10 that the key 29 of the locking pin 31 on the side remote from the free end is provided with a wedge shape 44, while the second part 25 of the bore 21 of the first hinge part 16 is on the side of the second hinge portion 17 turned end is provided with a cooperating wedge shape 45, which wedges 44 and 45 are formed such that the post section 10 and therefore the locking pin 31 remain in the fully retracted position against the spring pressure of the coil spring 25 by wedging the locking pin 31 in the second part 25 of the bore 21 of the first hinge part 16. The advantage of this is that the tent frame from the erected position is easier to fold in, because the hinges 11 between the post sections 10 and the hinges 12 at the location of the central cam element 6 can be locked in the unlocked position, allowing one person to fold the tent frame.
The invention is not limited to the exemplary embodiments described above and shown in the drawings, which can be varied in various ways within the scope of the invention. For example, the hinge pin 18 of the hinges 11, 12 can also be replaced by a folding hinge and the hinge parts 16, 17 can be formed in one piece. The post parts 10 can also be made substantially rigid.
