pose a safety problem in that there is a risk of falling from the buildings. A person falling from such a high-rise building would inevitably be seriously injured or even fatally injured. Even small objects, such as a bolt, falling from a high-rise building under construction can also cause serious injury to people passing underneath. All of these safety-related situations have spurred the development of high-rise safety devices.

Safety or protective nets are used in buildings under construction to prevent people or other objects from falling. Although the safety nets are useful for preventing objects or people from falling, they are not a very economical means because it takes time to install the nets and to remove them from the building once the building is completed. Furthermore, it is easy for a falling object or person to fall from a place not covered by the safety net. There is therefore a need for a high-rise safety device that is more effective and safer in protecting human lives.

Furthermore, in a high-rise building there is always a need for an emergency escape route device that allows people to escape the high-rise building from its full height. Emergency escape routes are already available on the market, but they usually require anchoring to the wall for support in order to

BOEHMERT & BOEHMEKT <

to support a fleeing person.

There is therefore a desire for a more effective and improved high-rise safety device that remains on the side walls of a high-rise building after the construction of the building is completed to serve as an anchor for emergency escape routes .

The object of the present invention is therefore in fact to provide a high-rise building safety device comprising a fixed part which is securely attached to the side wall of a high-rise building and a removable part which can be removably engaged with the fixed part so that a person, either a construction worker or a resident of the high-rise building, can hang on to it in order to prevent the person from falling.

Another object of the present invention is to provide a safety anchorage comprising a fixed part securely attached to the side wall of a high-rise building and a removable part removably engageable with the fixed part to form a handy, easily releasable anchorage for other safety devices, such as a safety net, so that such other safety devices can be installed in a time-saving manner due to the releasable engagement between the fixed part and the removable part.

Another object of the present invention is to provide a safety anchorage comprising a fixed member securely attached to the side wall of a high-rise building and a removable member removably engageable with the fixed member so that, due to the engagement between the fixed member and the removable member, a handy, easily removable anchorage for an emergency escape route device for high-rise buildings is provided, the fixed member being small and compact so that it can be fixed to the building walls without substantially affecting the external appearance of the building.

These objects are achieved by a safety anchorage according to claim 1.

Advantageous embodiments of the invention are described in the subclaims.

The safety anchor according to the invention comprises a fixed part which is to be securely fastened to a building frame under construction or to a side wall of a building, and a removable part which can be removably engaged with the fixed part in order to support or protect a person from falling from the building or the building frame. The fixed part has a widened base which is to be welded to the steel structure or to steel bars of a reinforced concrete structure or can be countersunk in the concrete structure, and a central hole in order to

&Bgr;&Ogr;&Egr;&EEgr;&Mgr;&Egr;&Kgr;&Ggr; & BOEHMERf j·";

to receive a removable part to be inserted therein. The removable part has a laterally projecting projection which is to be guided by a first slot formed on the inner surface of the bore when the removable part is inserted. The bore further has a circumferential slot formed on the inner surface thereof and in communication with the first slot and a retaining slot also connected to the circumferential slot but spaced from the first slot so as to be able to retain the removable part within the bore of the fixed part by moving the projection through the circumferential slot to enter and be retained in the retaining slot. A spring is seated within the bore to prevent inadvertent release of the projection from the retaining slot. A rope or cable is attached to the removable part to secure a person or object thereto.

The invention is described in more detail below using preferred embodiments with reference to a drawing, in which:

Referring to the drawings and in particular to Fig. 1, there is shown a high-rise safety device, hereinafter referred to as a safety anchor, constructed in accordance with a first embodiment of the present invention, the device being designated as a whole by reference numeral 100, the safety anchor 100 comprises a fixed part 1 and a removable part 2 which is to be removably engaged with the fixed part 1. The

BOEHMERT &&Bgr;&Ogr;&Egr;&EEgr;&Mgr;&Bgr;&Egr;&iacgr;··**;

The fixed part 1 preferably has the shape of a cylinder with a predetermined length along a central axis 101, with a base 11, which is preferably widened in the radial direction, being fixed to an axial end portion of the cylinder in order to be fastened to a frame structure of a building, for example to a steel structure frame 4 as shown in Fig. 10 or to a reinforced concrete frame 5 as shown in Figs. 11 and 12. The fixed part 1 further has a central, circular bore 10 which forms an opening at a free axial end portion of the fixed part 1 which is opposite the base 11 and extends along the central axis 101. The central bore 10 of the fixed part 1 is dimensioned to loosely receive the removable part 2 therein, so that the removable part 2 is detachably and removably received within the central bore 10 of the fixed part 1.

The removable part 2 is an elongated, cylindrical, piston-shaped part with a length corresponding to the length of the fixed part 1. The removable part 2 has on one of its end portions a fastening device for securing the body of a person or other object to be held on the side wall by means of the safety anchor 100. Preferably, the person securing device consists of a ring 22 which is attached to the opposite end portion of the removable part 2 to enable a rope, wire or cable 23 to be attached or tightened thereon, for example to carry a person 102, as shown in Fig. 10.

&Bgr;&Ogr;&Egr;&EEgr;&Mgr;&Egr;&Kgr;&Ggr; &BOEHMEitf; »**·

Referring now to Fig. 2, a portion of the fixed part 1 is cut away to show the internal structure of the part. The fixed part 1 has an axial slot 14 formed on the inner surface of the central bore 10 and extending from the opening of the central bore 10 to the bottom of the bore. The central bore 10 further has a circumferential slot 15 formed on the inner surface thereof and extending from a front end portion 151 communicating with the axial slot 14 to a rear end portion 152 communicating with a retaining slot 16. The retaining slot 16 is located on the inner surface of the central bore 10, the retaining slot 16 extending in a direction forming an angle with the circumferential slot 15. Preferably, the retaining slot 16 runs in the axial direction and thus forms a right angle with the circumferential slot. The retaining slot 16 is significantly shorter than the axial slot 14 and does not open into the free end section of the fixed part 1.

A biasing device, for example a coil spring 3, is arranged at the bottom of the central bore 10. Preferably, a recess 13 is provided at the bottom of the bore 10 into which the coil spring 13 is inserted and held in place, with a portion of the spring protruding from the recess 13.

The removable part 2 has a lateral wedge or projection 21 which corresponds to the axial slot 14 of the bore

10 and can be received therein when the removable part 2 is received within the central bore 10 of the fixed part 1.

In use, the removable part 2 is inserted into the bore 10 with the projection 21 received in the axial slot 14. The removable part 2 is then moved towards the bottom of the central bore 10 until it comes into contact with the spring 3. The removable part 2 is then moved further against the spring 3 until the projection 21 of the removable part 2 reaches the front end 151 of the circumferential slot 15, reference being made to Figs. 3, 5 and 6. Once the projection 21 of the removable part 2 has reached the front end 151 of the circumferential slot 15, the removable part 2 is rotated so that the projection 21 moves within and along the circumferential slot 15 until it reaches the rear end 152. The removable part 2 is then released and the spring 3 urges the removable part 2 away from the bottom of the central bore so that the projection 21 securely engages and is retained in the retaining slot 16, in which connection reference is made to Figs. 4, 7 and 8. This secures the removable part 2 within the fixed part, thereby securing any person or object attached to the removable part 2 via the cable 23. In this connection, the projection 21 has an axial dimension slightly smaller than the width or depth of the circumferential slot 15, measured in the axial direction 101, to enable the projection 21 to slide easily along the circumferential slot 15. The axial dimension of the retaining

BOEHMERT &BOEHMERt; ***

However, the width of the slot 16 should be greater than the width or height of the peripheral slot 15 so that a stop 160 is created which prevents the projection 21 from coming out of the holding slot 16 and thus effectively holds the projection 21 of the removable part 2 within the holding slot 16 and thereby also holds the holding part 2 securely in the central bore of the fixed part 1.

The movement of the projection 21 in the retaining slot 16 due to the biasing force of the spring 3 also causes a sound generated by the contact between the projection 21 and a side wall of the retaining slot 16. This forms an audible signal for the complete engagement or locking of the projection 21 with or into the retaining slot 16.

According to the present invention, the angle formed by the axial slot 14 and the retaining slot 16 and measured around the central axis 101 is approximately 135°.

To release the safety anchor 100, the removable part 2 is first pressed against the spring 3 towards the bottom of the bore 10 so that the projection 21 of the removable part 2 reaches the rear end 152 of the circumferential slot 15, and then the removable part 2 is rotated so that the projection 21 moves within the circumferential slot 15 and slides along it to reach the front end 151. The removable part 2 can then detach from the fixed part 1 by

BOEHMERT & BOEHMEiSN *";

- 12 -

Part is pulled axially outward from the bottom of the central bore 10.

In practice, the fixed part 1 can be secured to a steel structure frame 4 as shown in Fig. 10 by simply welding the base 11 to the steel structure 4. A number of such fixed parts 1 are distributed along the height of the steel structure frame 4 at desired positions on the steel structure frame. A building worker 102 can then use a single removable part 2 to secure himself at any desired position on the steel structure frame 4 with the cable 23 attached to his body to prevent him from falling from a supporting platform 103. Preferably, the cable 32 has a sufficient length to allow unhindered movement of the worker 102 within a certain range to carry out his work.

Still referring to Fig. 10, the fixed parts 1 attached to the steel structure frame 4 can also be used to suspend and support other construction equipment, such as a safety net 7. The releasable engagement of the removable part 2 with the fixed part 1 enables the safety net 7 to be installed or removed in a more convenient or time-saving manner.

Fig. 11 and 12 show how the safety anchor 100 can be used on a building frame 5 made of reinforced concrete. The fixed part 1 is shown in the

BOEHMERT & BOEHME^f: ·": ·"; *"

- 13 -

Concrete, the base 11 being fixed to the steel rods 41, for example by welding. The fixed part 1 can also be provided with two lateral legs 12, which can take the form of laterally extending rods, which are preferably arranged at a distance from the base 11 of approximately 3/5 of the length of the fixed part 1. The legs 12 can cross the steel rods 41 of the reinforced concrete structure 5, so that the fixed part 1 is even more firmly anchored within the concrete.

As shown in Fig. 12, similarly to the case of the steel structure frame 4 in Fig. 10, a number of fixed parts 1 are distributed on the reinforced concrete frame 5 to secure a person at any desired position.

Preferably, the fixed part 1 is secured to the frame 4 (or 5) in such a way that the ring of the removable part 2 lies in a vertical plane, as shown in Fig. 11, when the removable part 2 is inserted into the fixed part 1. Furthermore, the axial slot 14 of the fixed part 1 is preferably arranged at such an angle that when the removable part 2 is inserted into the bore 10 and the projection 21 is held within the retaining slot 16, the projection 21 and the retaining slot 16 are on the vertically upper side. This is because the gravity acting on the removable part 2 when a weight is suspended over the removable part 2 on the fixed part 1 tends to keep the projection 2 in a

- 14 -

Direction away from the bottom of the bore 10, causing the projection 21 to be held even more securely within the retaining slot 16. On the contrary, if the retaining slot 16 were located in the lower side, the gravity of the weight hanging from the fixed part 1 would tend to move the projection 21 towards the bottom of the bore 10, so that the projection 21 could inadvertently come out of the retaining slot 16.

In Fig. 13, another application of the safety anchor 100 according to the present invention is illustrated, where a number of fixed parts 1 are attached to a high-rise building 8 to enable an emergency escape route device 80 to be easily and quickly attached to the high-rise building by means of the removable engagement of the removable part 2 with the fixed part 1, so that the present invention also provides an emergency escape route device for high-rise buildings. The small size of the fixed part 1 enables the fixed part 1 to be attached to the building 8 without significantly disturbing the external appearance of the building 8. Furthermore, the fixed part 1 can be attached to the frame of the building 8 during its construction. Thereby, the fixed part 1, which is used in a building during construction for the safety of the construction workers, has a further function as an emergency escape route for the occupants of the building. Finally, the fixed part 1 does not need to be removed after completion of the construction work on the building.

In Fig. 9, a second embodiment of the present invention is shown, which is designated as a whole by reference numeral 200. In the safety anchor 200, the rod-like lateral legs 12 shown in Fig. 1 are replaced by rings 121. The rings 121 serve as hangers for hanging objects thereon. This is particularly advantageous when the safety anchor 200 is used in connection with a steel structural frame, since in this case the rings 121 are exposed and not embedded in the concrete of a reinforced concrete frame.

The features of the invention disclosed in the preceding description, in the drawings and in the claims can be essential both individually and in any combination for the realization of the invention in its various embodiments.
