DE2528230A1 - Fan heater housing with precisely reproducible tilting - uses flat strips acting as supporting rockers with recesses for return springs - Google Patents

Abstract

The fan heater housing comprises transverse base bars (2) which form chambers for receiving flat strips (4) acting as supporting rockers and which have upwardly and rearwardly inclined surfaces at the bottom, while the flat strips have downwardly and rearwardly inclined surfaces at the top. The base bars are formed by two parallel spaced adjacent walls (1) extending perpendicularly to the tilt axis, and wall sections connecting the ends of them. On the adjacent surfaces of the two spaced parallel walls are attachments on which the flat strips are mounted tiltably, and which may be formed by a common web connecting the two walls, or by coaxial pins (13) of which the free ends are spaced from each other. The flat strips may include recesses which form the tilt bearings and in which the pins engage automatically by return springs.

Description

Fan heater housing The invention relates to a fan heater housing Baseboards arranged transversely under the underside of the housing, the receiving chambers for Form flat strips serving as support rockers and in the case of the rear partial lengths the baseboards at the bottom to the back and the top and the flat strips at the top to the back and bottom have extending inclined surfaces, according to Patent O .... O .... (patent application P 25 o7 311.4).

The object of the invention is the tilting mobility of fan heater housings to improve according to the main patent and to achieve precisely reproducible tilting movements.

According to the invention this is achieved in that the baseboards by two walls arranged parallel to each other at a distance across the tilting axis and the end-face ends of the same connecting wall sections are formed in the shape of a shaft and that the walls on the sides facing each other serve as tilting axes Formations or the like.

have on which the flat strips can be slipped and tilted are held. The projections can be through one of the two walls of each skirting board connecting common web or by coaxial pins od. The like. Be formed, which end with the free ends at a distance from each other.

Attaching the preferably wedge-shaped at the edge edges Flat strips on the projections is easy in further development of the inventive concept accessible by means of recesses provided as tilting bearings in the flat strips which od the pins. Like. During the insertion process by pivoting back the ones carrying them Snap into place the previously spread walls. It is also conceivable that the recess with a Clear the slot opening into the edge of the flat strip less To be provided with a width over which the protrusions, e.g. the web, can be pushed into the recess and can be locked.

Finally, there are also measures to limit the tilting movements provided by the fact that the walls and / or the wall sections in the area of the upper End thrust bodies are assigned which, in the preferred embodiment, by sections the housing bottom are formed.

It corresponds to the idea of the invention that the arrangement of the baseboards not limited to a particular fan heater housing design or shape is. However, they are advantageous in fan heater housings with a quiver-shaped plug-in The front part of the housing and the rear part of the housing are formed solely by the skirting boards on the rear part of the housing.

The invention is illustrated in the drawing. Herein mean: Fig. 1 shows a fan heater housing in side view, partially in section, FIG. 2 is a partial section of a fan heater housing enlarged, FIG. 3 shows a partial section of a further fan heater and Fig. 4 is a flat strip in side view, enlarged.

The housing 1 is provided with a rear housing part 1 'and an attachable one Housing front part 1 "is formed. On its underside, the housing rear part has shaft-shaped Skirting boards 2 on, which are connected by parallel walls 11 and at the front Wall sections 12 are formed. The baseboards are on top of each other The ends are designed to be open and are used to accommodate upright standing and as a support rocker Serving flat strips 4. The flat strips 4 grip the walls 11 in an articulated manner at. To this end, the walls 11 either carry on the mutually facing side surfaces (Fig. 1 and 2) coaxially molded pins 13, which extend over partial widths of the receiving chambers 3 extend or (Fig. 3) a continuous web 14, while the flat strip 4 is provided with a recess 15 for this. When using tenons 13 the flat strip is connected by simply pressing it in into the space between the pegs, whereby the walls of the The pressing process is made possible and, after pressing, by springing back of the walls 11, the pins 13 engage in the recess 15. To facilitate the The pressing process is the upper edge of the flat strip 4 with inclined surfaces 16 provided. If a web 14 is used, the process of attaching the flat strip is carried out 4 by a slot 17 in communication with the recess 15 Width allows after expansion (Fig. 4) during the plugging process by springing back the flat strip is fixed in an articulated manner on the web 14.

To limit the tilting movement there are protruding parts in the receiving chamber Approaches 18 are provided which are formed by wall sections of the rear housing part 1 ' could be.

Patent claims fan heater housing with transversely under the underside of the housing arranged baseboards, the receiving chambers for flat strips serving as support rockers form and in the case of the back part lengths the baseboards down to the rear above and the flat strips above to the rear and downward extending sloping surfaces have, according to patent (patent application P 25 07 311.4), characterized in that that the baseboards (2) parallel to each other by two transversely to the tilting axis at a distance arranged walls (11) and the front ends of the same connecting wall sections (12) are shaft-shaped and that the walls (11) on the facing Sides serving as tilt axes od. The like. Have on which the flat strips (4) can be attached and held in a tilting manner.
