Description

Technical area

[0001] The invention relates to a shut-off device. State of the art

[0002] Barrier devices such as door or stair gates serve to create a functional barrier against uncontrolled entry or passage through a room. A door integrated into the barrier device allows controlled passage through the barrier. In practice, such barriers are regularly used to prevent small children and / or animals from leaving a specific room area or from entering a potentially dangerous area, such as a sloping staircase.

[0003] DE 20 2012 008 306 U1 discloses a barrier device of this type with a U-shaped frame, which is formed from two side elements and a common lower crossbar, via which the two side elements are connected to one another. The two side elements and the common lower crossbar form a U-shaped passage opening in which a door is arranged, which is pivotally attached to one of the two side parts. The lower crossbar also serves to accommodate clamping elements with which the barrier device can be clamped in a passage to be secured. For this purpose, the crossbar has bores with a threaded section at its end, into which and from which the clamping elements can be screwed in and out. In order to provide sufficient space to accommodate the clamping elements, the diameter of the crossbar must be sufficiently large.Due to its design, this results in a relatively high lower crossbar. Stepping through the opening is relatively difficult because the crossbar must be climbed over. Furthermore, the relatively high crossbar increases the risk of accidents caused by tripping when passing through the opening. Disclosure of the invention

[0004] The invention is based on the object of avoiding the disadvantages described and of providing a barrier device with a reduced risk of falling over and a more comfortable passage.

[0005] The object is achieved according to the invention by a shut-off device according to claim 1. Advantageous developments of the invention are specified in the subclaims.

[0006] The core of the invention is a barrier device with two side parts and a passage opening formed between the two side parts, in which opening a door element is arranged, wherein the two side parts are connected to one another via a common lower frame part, which forms the lower end of each of the two side parts and extends below the passage opening from one side part to the other side part, wherein the frame part has two outer end sections and a central section in the longitudinal direction, and the central section has a lower height than the end sections, and wherein a lower bearing device is provided which is arranged as a separate component on the central section immediately adjacent to an end section and wherein the end sections are each formed with a laterally outwardly open bore with a threaded section. The bearing device serves as a lower pivot bearing for the door.The invention has recognized that the lower frame part, which can be a frame strut, for example, can be designed with a central section extending along the passage opening, with a height that is reduced compared to the end sections, if the lower bearing device is designed as a separate component and is arranged on the central section immediately adjacent to an end section. The end sections have a greater height than the central section in order to be able to accommodate an outwardly opening bore that serves as a receptacle for clamping screws with which the barrier device can be clamped between vertical surfaces, e.g. two wall surfaces delimiting a passage. Because the lower frame part has a reduced height in the central section, climbing over the frame part when passing through the passage opening is considerably easier and the risk of accidents due to tripping is significantly reduced.

[0007] To increase the stability and structural stability of the barrier, the frame section has two different vertical segments in cross-section, with the lower segment extending to the height of the middle section and the upper segment extending to the height of the end sections, and with the lower segment being wider than the upper segment. In this design, the lower frame section has a low height in the middle section but a greater width in cross-section, thereby increasing stability. At the same time, this increases the support surface of the frame section, thereby increasing the stability of the barrier.

[0008] In a structurally simple embodiment, the bearing device for rotatably supporting the door comprises a bearing housing with a hollow cylindrical receptacle, wherein the door element is formed with a corresponding bearing pin which rotatably engages in the hollow cylindrical receptacle.

[0009] To implement an automatic closing function (“auto-close”), the bearing housing is designed with a torsion spring (also known as a leg or torsion spring) which interacts with the bearing pin in such a way that the door element pivots against the spring force when opened and closes automatically with the counter movement of the torsion spring.

[0010] To achieve a secured opening position (“open stop”), the bearing housing is designed with a locking means that engages a corresponding locking receptacle at a defined opening angle of the door element.

[0011] In order to securely close the passage opening, the door element is formed in its upper region, immediately adjacent to the side part opposite the storage device, with a handle element which has a movable bolt and the adjacent side part is formed with a latch, wherein the bolt engages in the latch in a locking position in which the door element closes the passage opening.

[0012] In order to allow smaller pets to pass through the barrier device independently, the door element is designed with a pivoting flap in its lower area, which is pivotally connected to the door element at its top.

[0013] In order to implement a locking function for the flap, the flap is formed with magnetic means on its underside, and the door element is formed with corresponding metal or magnetic means which are arranged in such a way that the magnetic means of the flap are in operative connection with the metal or magnetic means of the door element in the open state.

[0014] To ensure that the flap is locked more securely, the flap is designed with at least one sliding latch, with which it can be brought into a detachable, positive connection with the door element or the frame part when closed.

[0015] Further advantages of the invention are described in more detail below, together with the description of preferred embodiments of the invention, with reference to the figures. They show: Fig. 1 a front view of an embodiment of a shut-off device, Fig. 1a the view of section A from the Fig. 1, Fig. 1b a side view of the frame strut of the barrier device according to Fig. 1a, Fig. 2 a front view of another embodiment of the shut-off device, Fig. 3 a front view of the shut-off device according to Fig. 2 with small animal flap open.

[0016] The Fig. 1 shows a shut-off device 1 in a front view. The Fig. 1a is a detail view of the lower right area A of the Fig. 1. Fig. 1b shows a side view of a section of the Fig. 1a from the direction of arrow B according to Fig. 1a. The barrier device 1 can be used as a stair or door safety gate. It comprises two side parts 2a and 2b, between which the door element 3 is arranged, which blocks a passage opening formed between the two side parts 2a, 2b. For this purpose, the door element 3 and the side parts 2a, 2b have several vertical struts 4, of which Fig. 1 For the sake of clarity, only the right outer vertical strut 4 of the side part 2b and another strut of the door element 3 are numbered as examples. The distance between the vertical struts 4 is selected depending on the intended use and the size of the persons (infants, small children) or animals (guinea pigs, cats, dogs) that are to be prevented from passing through by the barrier. The side parts 2a, 2b are connected to one another by a common frame part, namely the lower frame strut 5. For this purpose, the frame strut 5 extends over the entire lower edge of the barrier device 1 and at the same time forms the lower end of each of the two side parts 2a and 2b. The frame strut 5 has two outer end sections 5a and 5b and a central section 5c. The central section 5c has a significantly lower height than the end sections 5a and 5b.Immediately adjacent to the end section 5b, on the right-hand side of the middle section 5c, the bearing device 6 is arranged. The bearing device 6 consists of a bearing housing in which a hollow cylindrical receptacle (not shown in the figures) is formed, which receives a bearing pin (not shown in the figures) that extends vertically downwards from the sleeve 7, which encompasses the outer right end of the lower door strut 8 of the door device 3. Furthermore, a torsion spring (not shown in the figures) is arranged in the bearing housing of the bearing device 6, which interacts with the bearing pin of the sleeve 7 in such a way that the door element 3 pivots against the spring force of the torsion spring when opened and closes automatically with the countermovement of the torsion spring.The bearing device 6 is also designed with a locking means (not shown in the figures) which, at a defined opening angle of the door element 3, engages a corresponding locking receptacle (not shown in the figures), thereby securing the door element 3 in the open position (“open stop”). To securely close the passage opening, the door element 3 is designed with the handle element 9 at the top left corner, which has a movable bolt (not shown in the figures). The adjacent side part 2a is designed with a latch (not shown in the figures) corresponding to the bolt, which is arranged in the latch housing 10. In order to be able to easily position the barrier device 1 between two vertical surfaces, e.g., two wall surfaces delimiting a passage, the end sections 5a and 5b are each designed with a bore opening to the outside and having a threaded portion.Of these holes, . Fig. 1b shows bore 11 as an example. Fig. 1b shows the end section 5b in a side view from the direction of arrow B in Fig. 1. In order to clamp the barrier between two walls, the clamping screws 12 and 12' are screwed into the corresponding holes in the end sections 5a and 5b. The upper struts of the side sections 2a and 2b have corresponding holes in which the clamping screws 12'' and 12'''' are inserted. The view of the Fig. Figure 1b further shows the profile of the lower frame strut 5, whose lower segment 13 is wider than the upper segment 13'. The boundary between the two vertical segments 13 and 13' is in Fig. 1b is symbolized by a dashed line for clarity. In section 5a, the frame strut 5 also comprises two corresponding vertical segments. Due to the greater width, the frame strut 5 also has a relatively high stability in the central section 5c, where it has a low height and is formed solely from segment 13. At the same time, the support surface of the frame strut 5 is enlarged due to the greater width of the lower segment 13, whereby the barrier device 1 has increased stability.

[0017] The Fig. Figure 2 shows the locking device 1', which is largely similar to the locking device 1. However, unlike the locking device 1, the locking device 1' is designed with a small animal flap 14. The small animal flap 14 is pivotally connected to the door element 3' on its upper side by hinges 15 and 15'. On its underside, the small animal flap 14 is designed with magnetic means 16 and 16', with which the small animal flap 14 can be locked in the open state. The sliding locks 17 and 17' can be used to positively lock the small animal flap 14 to the door strut 8' in the closed state. The illustration of the Fig. 3 shows the locking device 1' with the small animal flap 14 locked in the open state. In this state, the magnetic means 16 and 16' engage on the Fig.3 non-visible side of the small animal flap 14 is force-fitted to the struts 4'' and 4''', which are made of sheet iron and are therefore ferromagnetic. The passage 18 is open so that small animals can pass through the barrier device 1', while larger persons or animals are still prevented from passing through.
