Abstract
Abstract A fire-resistant cupboard (1) having, at its front side (3), selfclosing folding doors (6, 7) which can be locked (8) in the open position, said locking (8) being adapted to be released by means of a temperature sensitive element (10), and provided with closing means in the form of a vertically displaceable weight (11) connected to a corresponding folding door (6, 7) by means of a cable (12), which folding door is, in particular, not provided with door closing latches, shielded means (22) being provided for relieving an internal pressure rise when the doors (6, 7) are closed, and an internal air flow along the fixed edges (25) of shelves (26) provided in the cupbaord (1) is possible. The temperature sensitive element (10) also controls a safety valve (18) in a suction aperture (16) which is directly connected to a tensioning element of said temperature sensitive element (10).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A fire-resistant cupboard with fixed walls made of plate material with an insulating and incombustible inner coating, and with, at the front side, at least one folding door consisting of at least two panels and connected at one side to the fixed cupboard part by means of hinges, which door is urged towards the closed position by a closing means, and can be retained in the open position by a retaining locking bolt, the latter being coupled with a spring loaded tensioning element, the latter being adapted to be latched, in the tensioned condition and to be released by means of a temperature sensitive actuating element as soon as the temperature outside the cupboard rises above a given value, the released tensioning element releasing the door locking bolt, characterised in that the closing means for a folding door is formed by a vertically displaceable weight which is coupled with the folding door by means of a cable guided by rollers.
Claim 2
Dependent Claim
160 words
A fire-resistant cupboard with fixed walls made of plate material with an insulating and incombustible inner coating, and with, at the front side, at least one folding door consisting of at least two panels and connected at one side to the fixed cupboard part by means of hinges, which door is urged towards the closed position by a closing means, and can be retained in the open position by a retaining locking bolt, the latter being coupled with a spring loaded tensioning element, the latter being adapted to be latched, in the tensioned condition and to be released by means of a temperature sensitive actuating element as soon as the temperature outside the cupboard rises above a given value, the released tensioning element releasing the door locking bolt, characterised in that the closing means for a folding door is formed by a vertically displaceable weight which is coupled with the folding door by means of a cable guided by rollers.
Claim 3
Dependent Claim
33 words
The cupboard of claim 1, characterised in that the folding door is not provided with door closing latches and in that the closing weight is sufficiently heavy for keeping the folding door closed.
Claim 4
Dependent Claim
66 words
The cupboard of claim 1 or 2 with an air suction opening, characterised in that the air suction opening is provided at the lower side in the rear wall, and in that the lateral walls of the cupboard are extended beyond the rear wall in order to define an air supply duct which is laterally isolated as soon as the cupboard is placed against a wall.
Claim 5
Dependent Claim
20 words
The cupboard of claim 3, characterised in that the lateral wall extensions are formed by channels receiving a closing weight.
Claim 6
Dependent Claim
30 words
The cupboard of any one of claims 1..4, characterised in that the outer panel is guided near its free terminal edge only at its upper side in an open channel.
Claim 7
Dependent Claim
52 words
The cupboard of claim 5, characterised in that the folding door near its free terminal edge and at its lower side is provided with a pin which, when approaching the closed position, can grip behind a fixed claw which can keep the end panel at the lower side in the closed condition.
Claim 8
Dependent Claim
73 words
The cupboard of any one of claims 1..6, having a suction aperture in the upper wall provided with a security valve adapted to be closed at a temperature rise, characterised in that the security valve for the suction aperture is a drop valve which is directly coupled with the tensioning element by means of a bell crank in such a manner that the valve is open in the tensioned condition of said element.
Claim 9
Dependent Claim
55 words
The cupboard of any one of claims 1..7, in which the inner panel of a folding door near its hinge connection with the outer panel is provided with a handle for opening the folding door, characterised in that this handle is in the form of a continuous bar situated at some distance from this panel.
Claim 10
Dependent Claim
48 words
The cupboard of any one of claims 1..8, provided with shelves to be fixed on vertical stiles, characterised in that these stiles protrude in respect of the adjacent wall so as to leave free a ventilation passage between the nearby border of a shelve and the adjacent wall.
