DE4002799C2 - Vertical sliding sliding door for an open fireplace - Google Patents

Description

The invention relates to a vertically guided lift and slide door with at least one glass pane, for an open fireplace with Fire pit, side walls, rear wall, extractor hood and one on the side walls, a base plate and the top to the rear inclined panel attached door frame to his Side parts rails for guiding the ver with guide bolts see lift and slide door and means for vertical movement of Has counterweights, the train deflected over rollers ropes are connected to the lift and slide door, the lifting sliding door has a tilting wing, which is in one vertically movable frame in which it is located around its lower front longitudinal edge is tiltable.

Lift and slide doors for open fireplaces are already known, which are guided in rails and with the help of Aus Balance weights can remain in any opening position. However, these doors are moved tangentially to the door frame, causing considerable frictional loads on the door frame seals occur. The wear of the seals is relatively large, so that they need to be replaced from time to time. Around To close such doors tightly, an additional must Closure system can be attached.

A front end door is known from DE 32 48 467 A1, which is designed as a folding door that is perpendicular to Let the door frame open from below. Here, the Seals are not particularly stressed, but they occur when Opening the door creates an additional vacuum, which creates smoke can be moved into the living room. Another disadvantage is in this known system that the door when Pulling it out of its U-shaped bar at an angle into the room protrudes from the fireplace opening and in this position by hand must be kept. A cleaning of the pane or a  Replacing them is therefore tedious and can only practically be carried out by two people.

EP 03 14 590 A1 is a further lift and slide door for an open fireplace known, in which the lift and slide door one Tilting wing that moves in a vertically movable Frame is located in around its lower front longitudinal edge is tiltable. A lock in any Tilting is not possible.

The invention has set itself the task of a vertical propose movable lift and slide door, which without further Aid closes tightly, no noticeable when opened causes additional vacuum and for cleaning or Change the pane and let it fold out, which assumes a stable position in every position.

According to the invention, this object is achieved by that the front lower edge of the frame of the lift and slide door with the bottom sash is connected via a hinge strip, and the upper part of the bottom-hung sash with ropes guided over rollers is connected to a vertically movable counterweight.

This ensures that the lift and slide door is different from her the upper edge can be opened so that the inner part of the pane is immediately accessible in a simple manner.

The upper part of the tilting wing is in further training by the Erfin with vertically movable counterweights with ropes connected, which are guided over rollers. This will ensures that the bottom-hung sash is the same in every position weight. For changing or cleaning the pane therefore, the person performing the work has both Hands available.  

For perfect sealing of the lower part of the lifting rail The vertically movable frame of the same lies with the door its lower end when the door is closed a bar arranged on the base plate.

The lift and slide door can be L- or U- be formed leg. With an L-shaped version the leg can be on the right or left side of the front disc be arranged.

The upper front edge of the tilting wing has locking elements, which can be snapped into counter elements located on the frame are formed.

The invention is described in more detail with reference to the drawings.

Here show:

Figure 1 is a perspective view of a fireplace with lift and slide door in the tilt position.

Fig. 2 shows a detail of the sliding mechanism in the fireplace hood in a perspective view

Fig. 3 shows the upper part of a frame with a tilting wing of the lift and slide door.

Fig. 1 shows, in schematic and perspective view of a fireplace 1 with a tiltable lifting sliding door 2. The combustion chamber 3 of the chimney 1 is delimited by the side wall 4 and the rear wall 5 . The hood 6 is provided with an oblique front surface. Under the hood 6 there are cables 7 , pulleys 8 and counterweights 9 , as can be seen from FIGS. 2 and 3.

The lift and slide door 2 consists of a vertically movable frame 10 which can be moved into the hood 6 by means of the cables 7 , deflection rollers 8 and the counterweight 9 . The balance weight 9 is provided with a slide guide 11 which is guided by the slide rod 12 . The frame 10 is provided on the sides with guide bolts 13 which run in the rails 14 . The balance weight 9 is dimensioned such that the lift-slide door 2 assumes a stable position in every position, so that only small forces are required to overcome the friction in order to change the position.

With the frame 10 of the lift and slide door, a tilting wing 15 is tiltably connected via a hinge strip 16 or individual hinges. In its upper area, the tilting wing 15 is provided with latching elements 17 and 18 , which snap into the upper crossbar 19 of the frame 10 or jam with it.

The tilting wing 15 is provided with its own balance weight 20 , which is connected to a rope 21 guided over the roller 22 . The balance weight 20 , which is arranged in the rear vertically movable frame part, is in turn vertically movable and is dimensioned such that the tilting wing 2 retains its position in each tilting position. This ensures that only a very small force is required to carry out the tilting process and that the person who wants to clean the pane or replace it can use both hands for this purpose, since it is not necessary to hold the tilting wing.

The cables of the cables are preferably made of steel.

The bottom-hung sash consists of a frame with a U-profile, in which there is a seal and in which the glass pane is held. When using an L-shaped tilting wing, the glass panes encountered are worked together. The frame member 23 serves as a support member for the hood hood.
