Definitions
- the present invention relates to a handrail for a fire-fighting rescue cage.
- Such cages must fulfil certain safety requirements.
- One of these requirements is that a person accommodated in the rescue cage must be prevented from falling out accidently.
- modern rescue cages are provided with a continuous handrail running over the top of the walls of the framework of the cage.
- the respective opening portion of the handrail must be prevented from being opened unintentionally to keep its securing function.
- opening the handrail should be easily performed effortless even by an inexperienced User.
- the handrail according to the present invention comprises an opening section that can be opened by a pivoting movement around a pivoting axis.
- This opening section comprises a bar that is disposed in an approximately horizontal plane in a closed position of the handrail.
- This bar is attached to a frame element of the handrail by a hinge bearing.
- the hinge bearing comprises the pivoting axis, which is inclined downwardly with respect to the plane in which the bar is located in the closes state and extending outwardly from the framework of said cage.
- the bar can be pivoted from its closed state into an opened upright state wherein it does not block the free passage that is now provided in the opened state of the handrail.
- the bar is turned over around the pivoting axis, there is no danger of any interference with a person crossing the exit of the cage. There is also no danger that the bar falls back into its closed position accidently. Although it can keep its closed position because of its own weight, the opening section can be opened easily even by inexperienced users in a rescue situation.
- said bar comprises two sections being angled with respect to each other, both sections lying in a horizontal plane in the closed position.
- This embodiment is especially suited for arranging the opening section at one corner of the rescue cage, wherein a bending between these two sections can be arranged over the corner of the framework of the cage.
- pivoting axis lies within a vertical plane that encloses an angle between about 120° and about 140° with at least one adjacent wall of the cage.
- said hinge bearing is disposed at a corner of the rescue cage, and an end section of the bar lies approximately parallel to a first wall of the cage in the closed position and approximately parallel to a second wall of the cage in the opened position.
- the hinge bearing comprises an inner shaft portion being fixed to the frame element and extending outwardly therefrom in a downwardly inclined direction, and a sleeve being supported pivotally on said shaft portion and being fixed to said bar.
- said hinge bearing further comprises a flange being attached to the end of the inner shaft portion, said flange being press-held against an outer end of said sleeve to pinch the sleeve between the flange and the frame element.
- the sleeve can be held in its angular pivoting position by the friction between the flange and the frame element, respectively and the end faces of the sleeve. This friction holds all the parts being turnable with respect to each other in their turning position.
- the turning movement is not completely blocked so that the bar can still be pivoted at the hinge bearing into any desired position that is held automatically when no force by the user acts on the bar. That is, the flange for pressing the sleeve against the frame element represents a mechanism to hold the bar in its turning position.
- said hinge bearing further comprises a friction disk arranged between an inner end of said sleeve and the frame element.
- This friction disk increases the friction between the sleeve and the frame element, so that the bar can only be moved against this increased friction.
- the friction can be such that the bar keeps any angular position when no torque is applied to the bar.
- the hinge bearing further comprises a spring arranged concentrically within the sleeve to bias said flange against the outer end of the sleeve.
- Fig. 1 shows a fire-fighting rescue cage generally denoted by reference number 10.
- This rescue cage 10 is provided to be suspended on top of a ladder set that is carried by a fire-fighting vehicle. Together with the ladder set, the rescue cage 10 can be lifted into an operating position.
- the fire-fighting rescue cage 10 comprises numerals elements as fire-fighting equipment, for example, a water monitor and control elements for moving the rescue cage 10 at an operating stand located inside the cage 10. These elements have no further relation to the teaching of the present invention, and a description thereof will be omitted.
- the rescue cage 10 comprises a flat rectangular bottom 12 and a framework 14 rising from this bottom 12, said framework 14 comprising four cage walls, namely a front wall 16 comprising a front plate, a right side wall 18, a left side wall 20 and back wall 22.

- Another passageway 28 is located at a front right corner of the cage 10 where the front wall 16 and the right wall 18 meets. This passageway 28 is also closed by doors 30 that can be opened or closed by a user.
- a handrail 32 is disposed that encloses the top opening of the cage 10 completely. At the locations where the passageways 24,28 of the cage 10 are disposed, this handrail 32 can be opened.
- the opening mechanism for the first passageway 24 at the rear wall 22 of the cage 10 will not be described here.
- an opening section 34 is provided that can be opened easily by a user but keeps its closed position when no force acts on the opening section.
- the opening section 34 of the handrail 32 is formed by a tubular bar 36 that lies in the same plane as the remaining bars 38 fixed on top of the walls 16,18,20,22, forming the remains of the handrail section 32.
- This plane is disposed approximately horizontal in an operation position of the cage 10.
- the bar 36 comprises two bar sections, namely a first section 40 lying in the same vertical plane as the front wall 16 and being disposed on the same axis as the section of the handrail 32 that is fixed on top of this front wall 16, and a second section 42 that connects the first section 40 with a hinge bearing 44 for pivotably attaching an end of the bar 36 to a pillar-shaped frame element of the handrail 32.
- This hinge bearing will be described further in greater detail.
- the hinge bearing 44 is arranged such that the bar 36 can be lifted and turned from the closed position in Fig. 1 to their open position in Fig. 2 , wherein the bar 36 does not longer block the passage way 28 at the right front corner of the cage 10.

- the pivoting axis A lies within a vertical plane that encloses an angle of about 135° with the adjacent front wall 16 and the side wall 18 of the cage 10.
- the hinge bearing 44 further comprises a disc-shaped flange 52 being attached to the end of the inner shaft portion 48 and being press-held against the outer end face of the sleeve 50. More precisely, the flange 52 is biased with a predetermined biasing force along the pivoting axis A against the respective end face of the sleeve 50 so that the sleeve 50 in pinched between the flange 52 and the end face of the frame element 46. This biasing force is such that the turning movement of the bar 36 is not blocked but the bar 36 keeps any desired turning position when operated by a user. This is due to the friction between the contact phases of the flange 52 and the sleeve 50, on one hand, and the sleeve 50 and the frame element 46. Between the sleeve 50 and the frame element 46, a ring-shaped friction disk 54 is provided that increases the friction between the sleeve 50 and the frame element 46.

Description
- The present invention relates to a handrail for a fire-fighting rescue cage.
- Rescue cages that are mounted on top of ladder sets of fire-fighting vehicles for accommodating persons in a rescue situation. An example of a known rescue cage is disclosed in
US 2002/100637 . - Such cages must fulfil certain safety requirements. One of these requirements is that a person accommodated in the rescue cage must be prevented from falling out accidently. For this reason modern rescue cages are provided with a continuous handrail running over the top of the walls of the framework of the cage. On the other hand, it should be possible to leave the cage whenever it is necessary. Therefore it should be possible to open the handrail, so that a person inside the cage can cross the handrail and move out. The respective opening portion of the handrail must be prevented from being opened unintentionally to keep its securing function. However, opening the handrail should be easily performed effortless even by an inexperienced User. In particular care should be taken that no part of the handrail is in the way when the person leaves the cage, so the opened handrail should not interfere with the opening representing the escape passageway from the cage. There are certain prescriptions that for safety reasons the handrail should only be opened in an inward or upward direction. These requirements can hardly be fulfilled by handrails according to the state of the art. To be opened towards an inward direction has some disadvantages because the opening section easily interferes with the user.
- It is therefore an object of the present invention to provide a handrail for a fire-fighting rescue cage that keeps the handrail secure in its closed position without any danger of being opened accidently but can be opened easily when desired, without any parts interfering with the passage opened in the handrail. It is another object of the present invention to provide a handrail that can only be opened in an upward direction without interfering with a user.
- This object is achieved by a handrail for a fire-fighting rescue cage comprising the features of claim 1.
- The handrail according to the present invention comprises an opening section that can be opened by a pivoting movement around a pivoting axis. This opening section comprises a bar that is disposed in an approximately horizontal plane in a closed position of the handrail. This bar is attached to a frame element of the handrail by a hinge bearing. The hinge bearing comprises the pivoting axis, which is inclined downwardly with respect to the plane in which the bar is located in the closes state and extending outwardly from the framework of said cage.
- Because of this inclination and outwardly directed arrangement of the pivoting axis, the bar can be pivoted from its closed state into an opened upright state wherein it does not block the free passage that is now provided in the opened state of the handrail. When the bar is turned over around the pivoting axis, there is no danger of any interference with a person crossing the exit of the cage. There is also no danger that the bar falls back into its closed position accidently. Although it can keep its closed position because of its own weight, the opening section can be opened easily even by inexperienced users in a rescue situation.
- According to a preferred embodiment of the present invention, said bar comprises two sections being angled with respect to each other, both sections lying in a horizontal plane in the closed position.
- This embodiment is especially suited for arranging the opening section at one corner of the rescue cage, wherein a bending between these two sections can be arranged over the corner of the framework of the cage.
- Preferably said pivoting axis lies within a vertical plane that encloses an angle between about 120° and about 140° with at least one adjacent wall of the cage.
- According to another preferred embodiment, said hinge bearing is disposed at a corner of the rescue cage, and an end section of the bar lies approximately parallel to a first wall of the cage in the closed position and approximately parallel to a second wall of the cage in the opened position. According to another preferred embodiment, the hinge bearing comprises an inner shaft portion being fixed to the frame element and extending outwardly therefrom in a downwardly inclined direction, and a sleeve being supported pivotally on said shaft portion and being fixed to said bar.
- Preferably said hinge bearing further comprises a flange being attached to the end of the inner shaft portion, said flange being press-held against an outer end of said sleeve to pinch the sleeve between the flange and the frame element. In this arrangement the sleeve can be held in its angular pivoting position by the friction between the flange and the frame element, respectively and the end faces of the sleeve. This friction holds all the parts being turnable with respect to each other in their turning position. However, the turning movement is not completely blocked so that the bar can still be pivoted at the hinge bearing into any desired position that is held automatically when no force by the user acts on the bar. That is, the flange for pressing the sleeve against the frame element represents a mechanism to hold the bar in its turning position.
- Preferably said hinge bearing further comprises a friction disk arranged between an inner end of said sleeve and the frame element.
- This friction disk increases the friction between the sleeve and the frame element, so that the bar can only be moved against this increased friction. The friction can be such that the bar keeps any angular position when no torque is applied to the bar.
- According to another preferred embodiment, the hinge bearing further comprises a spring arranged concentrically within the sleeve to bias said flange against the outer end of the sleeve.
- These and other objections, advantages and features of the present invention will be become more apparent from the following description with respect to the accompanying drawings.
-

Fig. 4 is a top view of the opening section of the handrail according to this embodiment of the present invention according toFig. 3 . -
Fig. 1 shows a fire-fighting rescue cage generally denoted byreference number 10. Thisrescue cage 10 is provided to be suspended on top of a ladder set that is carried by a fire-fighting vehicle. Together with the ladder set, therescue cage 10 can be lifted into an operating position. The fire-fighting rescue cage 10 comprises numerals elements as fire-fighting equipment, for example, a water monitor and control elements for moving therescue cage 10 at an operating stand located inside thecage 10. These elements have no further relation to the teaching of the present invention, and a description thereof will be omitted. - The
rescue cage 10 comprises a flatrectangular bottom 12 and a framework 14 rising from thisbottom 12, said framework 14 comprising four cage walls, namely a front wall 16 comprising a front plate, aright side wall 18, aleft side wall 20 andback wall 22. Theback wall 22 comprises apassage way 24 for leaving therescue cage 10 throughdoor wings 26 that can be opened by a person inside the cage and close automatically. Anotherpassageway 28 is located at a front right corner of thecage 10 where the front wall 16 and theright wall 18 meets. Thispassageway 28 is also closed bydoors 30 that can be opened or closed by a user. - On top of the
walls cage 10, ahandrail 32 is disposed that encloses the top opening of thecage 10 completely. At the locations where thepassageways cage 10 are disposed, thishandrail 32 can be opened. The opening mechanism for thefirst passageway 24 at therear wall 22 of thecage 10 will not be described here. On the front right corner of thecage 10, anopening section 34 is provided that can be opened easily by a user but keeps its closed position when no force acts on the opening section. - The
opening section 34 of thehandrail 32 is formed by atubular bar 36 that lies in the same plane as theremaining bars 38 fixed on top of thewalls handrail section 32. This plane is disposed approximately horizontal in an operation position of thecage 10. Thebar 36 comprises two bar sections, namely afirst section 40 lying in the same vertical plane as the front wall 16 and being disposed on the same axis as the section of thehandrail 32 that is fixed on top of this front wall 16, and asecond section 42 that connects thefirst section 40 with a hinge bearing 44 for pivotably attaching an end of thebar 36 to a pillar-shaped frame element of thehandrail 32. The construction of this hinge bearing will be described further in greater detail. - The hinge bearing 44 is arranged such that the
bar 36 can be lifted and turned from the closed position inFig. 1 to their open position inFig. 2 , wherein thebar 36 does not longer block thepassage way 28 at the right front corner of thecage 10. In this open position, there is no danger that thebar 36 falls accidently back into its closed position. Thefirst section 40 of thebar 36 is then pointing backwards in an upright direction, standing approximately parallel to theright wall 18 of the cage 10 (or being inclined slightly inwards in the direction of the right rear corner of the cage 10). Any interference with a person crossing thepassageway 28 is avoided in this position of thebar 36. - The mechanism of the hinge bearing 44 is described in greater detail with reference to
Fig. 3 . This figure shows theopening section 34, i.e. thebar 36 in the closed position according toFig. 1 from another perspective. Bothsections bar 36 lie in the same horizontal plane, being angled with respect to each other and enclosing an angle of approximately 120°. By the hinge bearing 44, thesecond section 42 of thebar 36 is connected to a pillar-shapedframe element 46 of the framework 14 of thecage 10. From theframe element 46, ashaft portion 48 extends outwardly with respect to the construction of thecage 10, the axis of thisshaft portion 48 being inclined downwardly. This axis, marked by reference A inFig. 3 , represents the pivoting axis of the hinge bearing 44 around which thebar 36 can be turned into its open position. Onto thisshaft portion 48, asleeve 50 is supported pivotably to be turned around the pivoting axis A. The outer peripheral surface of thesleeve 50 is fixed to thesecond section 42 of thebar 36. That is, a torque can be applied at thebar 36 and transmitted to thesleeve 50 to be turned around the pivoting axis A of theinner shaft portion 48. The pivoting axis A lies within a vertical plane that encloses an angle of about 135° with the adjacent front wall 16 and theside wall 18 of thecage 10. - The hinge bearing 44 further comprises a disc-shaped
flange 52 being attached to the end of theinner shaft portion 48 and being press-held against the outer end face of thesleeve 50. More precisely, theflange 52 is biased with a predetermined biasing force along the pivoting axis A against the respective end face of thesleeve 50 so that thesleeve 50 in pinched between theflange 52 and the end face of theframe element 46. This biasing force is such that the turning movement of thebar 36 is not blocked but thebar 36 keeps any desired turning position when operated by a user. This is due to the friction between the contact phases of theflange 52 and thesleeve 50, on one hand, and thesleeve 50 and theframe element 46. Between thesleeve 50 and theframe element 46, a ring-shapedfriction disk 54 is provided that increases the friction between thesleeve 50 and theframe element 46. - The
bar 36 can only be moved, i.e. turned around the hinge bearing 44 against this friction. - The biasing force to press the
sleeve 50 together with theflange 52 against thefriction disk 54 and theframe element 46 is provided by aspring 56 that is disposed inside thesleeve 50 and wound around theinner shaft portion 48 to be arranged concentrically within thesleeve 50. Thisspring 56 is fixed, on one hand, to the frame element and with its other end to theflange 52 to pull theflange 52 along the pivoting axis A in the direction of theframe element 46. The free end of thebar 36, that is, thefirst section 40 can be provided with a locking means to connect the free end of thebar 36 to the framework 14 and to the remaining fixed section of thehandrail 32 that is not shown inFig. 3 . -
Fig. 4 further shows a top view of the opening section ofFig. 3 , demonstrating the angular arrangement of the twosections bar 36.
