• This invention is based on the astonishingly simple finding that the problems explained above in the prior art can be eliminated by using one and the same security element both to prevent the door leaf from falling in the event of a break in the traction means and as a burglar alarm.
• This securing element can possibly cooperate with one or more additional securing elements attached to the boundary walls of the space to be closed with the door leaf, in order to ensure the desired function. In this way it is achieved that in the area of the door leaf itself only one security element has to be provided as a catch and burglar alarm, which results in considerable design simplifications.
• security devices are also contemplated within the scope of this invention, in which two or more security devices of the type described above are attached in the region of the two lateral edges of the door leaf, each of which has a security element which acts both as a burglar alarm and a catch security device.
• the securing element equipped with the double function explained above can be designed to be particularly simple in terms of construction if it has a first securing segment, preferably in the form of a pawl protruding downward in the securing position, and a second securing segment, preferably in the form of a pawl protruding upward in the securing position ,
• at least one further securing element is fastened in the region of the first section of the predetermined path to a wall which delimits a space to be closed with the door leaf and which has an abutment for the first securing segment.

• At least one further security element is fastened in the region of the second section of the predetermined path to a wall which delimits a space to be closed with the door leaf and which has an abutment for the second security element.
• This abutment which interacts with the second securing segment, can also be designed with the avoidance of additional components in the form of a bulge of the side frame spar of the door which is open at the bottom in this case.
• the securing element of the securing device according to the invention is expediently fastened to the door leaf and preferably pivotally mounted on the door leaf with respect to a pivot axis running perpendicular to the predetermined path, so as to provide reliable securing while avoiding a structurally complex, displaceably mounted catch housing on the door leaf. It has proven to be particularly favorable if the securing element is designed in the manner of a securing lever which has the securing segments at one axial end and can be pivoted in the region of its other axial end about a pivot axis which is preferably approximately perpendicular to the predetermined path and parallel to the door leaf plane is stored.
• the securing element of the device according to the invention which is equipped with a double function according to the invention, can also assume a third function with which it switches off a drive device for the door leaf when the securing element is moved into the securing position.
• the securing element is preferably equipped in the region of the pivotable axial end on the door leaf with a control cam for actuating a switch of the drive device for the door leaf when the securing element is adjusted from the release position into the securing position.
• the securing element can be held in the release position to enable a door leaf movement if it is coupled to a traction means, preferably directly connected to it, with which it is pushed into the release position against the prestressing force of the prestressing device in the event of a tensile load.
• the securing element can be held in the release position with a relatively small force if the traction means is attached to the end of the securing element facing away from the pivot axis.
• the securing element is mounted on a catch housing which is held displaceably on the door leaf.
• these problems can be eliminated in that the securing element is pivotably mounted on a bolt which is fixed with respect to the door leaf.
• This bolt can, for example, be attached to an attachment piece fastened to the door leaf or can be used to attach this attachment piece to the door leaf.
• a door manufactured using such a door leaf comprises side frame spars in which the further securing elements explained above are provided.
• FIG. 1 is a schematic representation of a door leaf with a securing device according to the invention with the securing element held in the release position
• Fig. 4 is a schematic representation of the securing device according to the invention, in which the positions of the securing element shown in Figs. 1 to 3 are shown.
• the door shown in FIG. 1 comprises a door leaf 10, a side frame spar 20 fixed to a wall 5 defining the space to be closed with the door leaf 10, and a securing device designated as a whole by 30.
• the door leaf 10 can be moved between the closed position shown in FIG. 1 and an open position with a traction means designed as a pull chain 12 in the embodiment of the invention shown in the drawing, as indicated by the arrows A in FIG. 1.
• the pull chain 12 is fastened to the door leaf 10 via the securing device 30 attached to the lower edge of the door leaf 10.
• the securing device 30 comprises a housing 32 and a securing element 40, which is accommodated in the housing 32 and is pivotable on a bolt 36 which runs with its bolt axis parallel to the door leaf and perpendicular to the direction of movement of the door leaf and which has a connecting region 46 at its end facing away from the bolt 36 is connected to the pull chain 12.
• the securing element 40 has an opening in which the bolt 36 is received.
• the securing element 40 which is formed in the manner of a securing lever, has a first pawl 42 projecting downward and a second pawl 44 projecting upward.
• the securing element 40 is assigned a torsion spring 50, with which it is pushed in the direction of the wall 5.
• one end 52 of the torsion spring 50 is supported on the housing 32, while the other end 54 of the torsion spring 50 is supported on the securing element 40, so as to secure the securing element 40 from the release position shown in FIG. 1 in the direction indicated by the arrow B.
• the housing 32 is provided in the region of its boundary facing the wall 5 with an opening 34 through which the securing element 40 can pass. By pulling the pull chain 12, the securing element connected to it via the fastening area 46 is shown in FIG. 1 Release position held.
• the tensile stress acting on the securing element 40 is omitted, so that this securing element 40 passes through the opening 34 into the securing position shown in FIG. 2 under the action of the torsion spring 50.
• the pawl 42 engages in one of the upwardly open bulges 22 provided in the upper region of the side frame rail 20 and thus prevents the door leaf 10 from falling downward.
• the security element 40 is shown in its function as a burglar alarm. If the door leaf 10 is to be moved upward from the closed position shown in FIG. 3 with the aid of a lever 17 attached to the lower edge of the door leaf 10, the pull chain 12 is also relieved of strain. This applies even if the pull chain 12 is connected to a weight compensation device is coupled in the form of a torsion spring, provided the door is equipped with a shaft drive which blocks the spring shaft when the door is closed. Due to the strain relief of the pull chain 12, the torsion spring 50 in this case also causes the securing element 40 to be moved into the securing position in which the end of the securing element equipped with the pawls 42 and 44 is exposed outside the housing 32. During an opening movement of the door leaf, the second pawl 44 engages with abutments 24 formed in the form of bulges of the side frame spar 20 that are open towards the bottom, in order to block an opening movement of the door leaf.
• the security element 40 of the device according to the invention fulfills two functions, namely on the one hand securing the door leaf in the event of breakage of the traction means and on the other hand the function of protecting against burglary.
• a motor drive designed to move the door leaf 10 between the open position and the closed position is also switched off.
• the securing element 40 is equipped at its end fixed on the bolt 36 with a control cam 48 which, when the securing element is pivoted into the securing position, adjusts an actuating element 62 of a switch 60 in order to switch off the motor drive, as is particularly evident from a comparative view 1 on the one hand with FIGS. 2 and 3 on the other hand.
• the bulges 22 and 24 serving as further securing elements are designed such that the second pawl 24 engages with the bulges 24 at a pivoting angle ⁇ , which is less than a pivoting angle ⁇ which is used to engage the first pawl 42 is required in the bulge 22. It follows from this that in the sense of this description, each position of the securing element is to be regarded as a securing position in which a part of the securing element 40 is exposed outside of the housing 32.
• the invention is not limited to the exemplary embodiment explained on the basis of the description. Rather, such embodiments are also envisaged in which separate abutments are fixed to the wall 5 without a corresponding change in the side frame spar 20 being required. This embodiment is particularly advantageous for retrofitting existing gates. Furthermore, the pawls of the securing element of the device according to the invention can also have a different shape or be arranged at other locations. Furthermore, instead of a pull chain, a pull rope or a combination of a pull rope and a pull chain can be used, the pull chain being fixed to the door leaf and passing into a pull rope which can be wound on a winding drum fixed to the spring shaft.
