Description

The present invention relates to a device for closing openings of fire pits according to the preamble of claim 1 and a fireplace according to the preamble of claim 8, respectively. Claim 10.

Doors for closing openings of fireplaces, in particular openings of chimneys, are known in a number of embodiments.

Front openings of the firing areas, for example, of kitchen fireplaces are closed by pivotally mounted on the hearth doors. These doors are usually relatively small and thus the pivoting range is limited according to the wing width of the doors. For larger front openings and two mutually pivotable doors can be arranged, the pivoting range is also limited so. The hinges are arranged either vertically, for a horizontal pivoting movement, or horizontally, for a vertical pivoting movement. In any case, the maximum pivoting range of the door and a security area beyond the floor of the hearth must be equipped with refractory coating, so that any deposited on the inside of the door embers can cause no damage to the ground or even the ignition of a fire when falling. Thus, the swing doors are usually not suitable for use in front of large openings, as for example in chimneys resp. Cheminées are present.

For this example is from the DE 4236916A1 a push-up fireplace door known. In this case, a door is mounted on vertically arranged guide rails and can thus either be moved down in front of the chimney opening and thus they are closed or moved upwards and thus make the opening accessible. In order for the movement to be carried out by a user without much effort, the door is equipped with pulleys guided by rope pulleys connected to counterweights. This keeps the chimney door in the pushed-up, ie open position without additional locking.

Similar constructions are further for example from the DE 29514367 U , of the CH 688457 and the CH 674891 known. All these solutions have in common that the door respectively in front of the fireplace opening resp. Firing hole is moved from the closed position to an upper rest position. In order to keep the doors in the respective position, in particular in the upper rest position or possibly in an intermediate position, appropriate locking devices must be provided. Usually, cables with counterweights are used for this purpose as described above.

These locking devices require additional space resp. Room in the area of the closing device. Usually, the locking device is mounted concealed and thus requires space in the area of the firebox. These additional elements make the closing device complex and expensive to produce and in operation, as the elements under the influence of the heat of the firebox.

The object of the present invention was to find a closing device of the type mentioned for fireplaces such as open fireplaces or chimneys, which in addition to the reliable closure of the opening of the fireplace is easy to use and simple in construction.

This object is achieved by a device having the features of claim 1. Further embodiments of the invention will become apparent from the features of further claims 2 to 7.

In a device for closing openings of fireplaces with a door positionable in front of the opening and with the hearth and the door connected guide elements, the guide elements are arranged such that the door is substantially horizontally displaceable with respect to the opening of the fireplace and in the open position is arranged laterally of the opening. Due to the horizontal displaceability of the door no weighting of the door compensating measures such as balancing weights need to be provided more. Thus, the space required by the arrangement of these elements of conventional sliding devices can be saved. The reduction of the moving parts of the device also increases its reliability in operation and at the same time reduces the cost of the device due to the simplified structure.

Further, above the opening of the fireplace, no space is required for parking the door in the open state, so that the device is also suitable, for example, for cheminées protruding freely from the wall, which do not have an elevated structure in the region of the upper edge of the opening.

For example, the guide elements are formed from horizontally arranged in the region of the opening guide rails, in which fastening elements of the door are slidably mounted. This guide system can be used, as they are known for example from the furniture for pull-out drawers. These guide systems can be sized to suit the dimension and weight of the door and allow for easy sliding of the door from the closed position in front of the opening to a partially open or fully open position laterally of the opening. Due to the horizontal arrangement of the guide rails, the door remains fixed in virtually any position without additional means.

For the reliable locking in the end positions, in particular in the closed position, for example, simple locking means can be provided for the temporary locking, which can be overcome with only slightly increased force, but reliably prevent an independent, unintentional movement of the door.

For example, the device has two guide rails arranged in parallel. In this case, the one guide rail is mounted in the region of the upper edge of the opening or above and the second guide rail in the region of the lower edge of the opening or a possible existing Simses des Cheminées arranged. The lower guide rail may be arranged, for example, with an opening opening oriented vertically to the front or with an upward opening groove.

For example, the guide rails are formed extending straight over the entire length and arranged at an acute angle with respect to the plane of the opening in a direction parallel to the ground plane. The door is advantageously aligned parallel to the frame of the opening and is also lifted by the obliquely arranged guide rails when moving from the opening to the lateral position at the same time from the frame of the opening. Advantageously can be used straight guide rails, which are simple in construction and production and thus can be made inexpensively. Nevertheless, a reliable closure of the opening through the door is ensured.

For example, the connection between the door and guide rail is designed such that in the closed end position, an additional relative movement between the door and the guide rail can be done. Thus, for example, the door can be moved laterally in the closed position in front of the opening and thereafter by an additional sliding movement of the door horizontally perpendicular to the opening these are sealed.

For example, the door is at least partially transparent. This can also be closed Door of Feuerungsvorgang resp. the flame in the firebox can be observed from the outside. This can be realized, for example, by using clear or tinted refractory glass.

For example, directed at the edge region of the door against the plane of the opening sealing elements are arranged, preferably in the form of a circumferential, elastic sealing strip. For a reliable and complete sealing of the furnace from the environment in the closed state of the door is achieved. For example, this allows a controlled combustion within the furnace. Also, so that no exhaust fumes or smoke through the opening from the firebox reach the environment, but only on the ordinary chimney flue of the fireplace resp. of the Cheminée.

For example, the guide elements are designed as horizontally extending telescopic rails. By the use of telescopic rails, the space required for installation in the border of the opening resp. kept small in the opening and yet achieved a large displacement area of the door, i. The door can thus be moved almost or completely away from the opening and thus the firebox are made completely accessible from the outside.

Furthermore, according to the invention, a chimney with a combustion chamber opening lying essentially in one plane and having at least one device for closing the combustion chamber opening according to one of claims 1 to 7 is proposed. Such equipped cheminées can be simply operate with the door open, for example, equip with fuel and then operate safely and without affecting the environment with the door closed. The space required for the door in the open state is extremely low, to the front of the front of the fireplace no additional space is needed as a swing door and upwards also not what the design freedom of the design of the fireplace may increase. In some cases, there is free space at the side of the chimney, so that the movement of the door to open the firebox does not interfere with this area.

For example, a part of the guide elements consists of horizontally arranged, formed below and above the firebox opening guide rails. These guide rails can be inserted directly into the opening frame or the area of the chimney surrounding the opening and thus do not attract attention or hardly be noticeable.

Furthermore, according to the invention, a chimney with a furnace opening leading over the corner is proposed, in which two devices according to one of claims 1 to 7 are arranged such that the lateral edges of the two doors lie flush against each other in the closed position in the corner. Thus, it is also possible to close one over a reaching opening of a fireplace with the inventive construction.

In Figur1 For example, to see the view of a conventional Cheminées 1 with vertically push up door 2 in the open position. The door 2 is in this case arranged above the firebox opening 3 of the chimney 1 and is guided for this purpose via two vertically extending guide rails arranged laterally of the firebox opening 3. Within the fireplace side of the firebox are protected behind panels cables and counterweights to stabilize the door 2 arranged. On the one hand, these elements require space inside the fireplace and are on the other hand, difficult to access for maintenance or in case of failure.

In FIG. 2 is now the front view of a novel Cheminées 10 with closed door 11 shown. The door 11 is formed in this example as an approximately flat surface and covers the rectangular opening 12 of the fireplace completely.

In FIG. 3 the door 11 is now shifted laterally horizontally and thus releases the opening 12 to the firebox of the Cheminées 10. The lateral movement can be practically force-free without the assistance of a cable and the door will remain in virtually any position without additional means. Thus, advantageously the space for cables and in particular for conventional counterweights can be saved and thus either the dimension of Cheminées compared to conventional Cheminées be reduced or the space for a larger firebox or possibly other technical installations are used, such as a recirculation system.

In FIG. 4 a) is purely schematic of the partial section, for example, by the upper guide elements of the door 11 of the Cheminées after FIG. 2 shown. In the illustrated embodiment, a arranged in the frame 13 of the opening 12 guide rail 14 is shown, in which a slider 15 is arranged longitudinally displaceable, which is connected to the door 11. The slider 15 has, for example, rollers or rollers in order to allow the most resistance-free sliding movement of the door 11.

In FIG. 4 b) the door 11 is shown in approximately fully open position, that is shifted to a position left side of the opening 12. In this case, the slider 15 has arrived in its left position of the guide rail 14. The guide rail can according to the desired displacement of the door 11 are shorter, the same length or longer than the width of the opening 12 dimensioned.

It is clear to those skilled in the art that other sliding hardware for attaching the door 11 can be used, in particular known so-called telescopic fittings from furniture, which allow for the same length guide rails reliable guidance of the door 11 from the closed to the fully open position.

It is also conceivable, in each case in the end positions or optionally at additional intermediate positions of the door 11 to provide latching means on the guide elements in order to fix the respective position and to prevent an independent movement of the door 11 from these positions.

In the FIGS. 5 a) to c) an alternative embodiment of guide elements is shown which an additional horizontal movement of the door 11 in the direction of the opening 12, respectively. allow away from the opening 12.

In FIG. 5 a) the door 11 is shown in the open position to the left of the opening 12. The door 11 is connected to the guide rail 14 via a first slider 15 and a second slider 16. The first slider 15 is firmly connected to the door 11 and slidably mounted in the guide rail 14, the second slide 16 is fixedly connected to the guide rail 14 and slidably mounted in the door 11. Both slides 15 and 16 have joint connections to the respective section in the guide rail 14, respectively. the door 11 on. In the displacement position while the door 11 is spaced from the frame 13 and can, as in FIG. 5c) is shown, are moved to the opening 12.

By the hinge connection of the slide 15 and 16, the door 11 can then be moved against the frame 13 and placed in close contact, as shown in Figuzr 5 c).

The hinges of the slides 15 and 16 advantageously each have a locking in their end positions, so that the door 11 is fixed by the frame 13 either spaced or tightly positioned.
