Description

DOOR LOCK The invention relates to a door lock according to the preamble of claim 1. A door lock of this type was made known under the name "DORMA TS 77" and in practice it has been widely accepted due to its reliability and reliability. various application possibilities. The door lock can be mounted both on the inside and on the outside of a door leaf, as well as on the door frame. The arrangement of the door lock on the inside of the sheet is in principle problematic, since the sheet, when opened, moves in the direction of the adjacent wall and the lock is then between the door leaf and said wall. There is therefore a danger that, in the event of a too large opening angle of the door leaf, the lock will collide with the adjacent wall and be damaged, especially if the door is installed in the corner of a door. room or on a thick wall. In this type of applications, it is decided to limit the opening angle. Therefore, compact door locks with the lowest possible construction height are desired, while retaining the current plurality of applications and the various functions. The external dimensions, in particular the construction height, of the known door lock are too high due to the special internal configuration, so that for the packaging of the door lock a large amount of packaging material is required and In addition, the corresponding storage and transport space must be available. The angled external shape of the door lock causes manufacturing technology problems, due to hollow spaces of the material, and is not optimal in terms of economic material consumption. The invention is based on the objective of improving a door lock according to the preamble of claim 1, in such a way that a compact and optically attractive unit is obtained, which can be manufactured with a minimum of material and manufacturing work. Said objective is achieved by the characteristics indicated in the characterizing part of claim 1. Advantageous embodiments of the invention are characterized in the subclaims. The object of claim 1 has the advantage that, thanks to the compact external shape of the door lock, a low construction lattice can be achieved. In this way, the door lock is also suitable for being used under limited installation conditions, or unfavorable with respect to a limited opening angle of the door leaf. In principle, in the case of the above situation, a door lock must be preferred whose mechanical and hydraulic units are arranged in a longitudinal direction, in a corresponding channel of the body. Although the consumption of material for the body according to the invention is extremely small, stability and performance properties are guaranteed. All wall thicknesses have been reduced to a minimum. The external contours that result are optically attractive thanks to fluid and "burrless" transitions.The body has an elongated shape due to the series arrangement of the function units, adapting the lateral surfaces to the contours of the channel. A curved or oblique course of the lateral surfaces is ideal The fluid course of the external contours, especially of the lateral surfaces and of the trestles illustrated below, considerably reduces the consumption of material and the problems of the casting technique. __ _ __ _ _ _ In order for the output points of the drive shaft to be sufficiently stable, the side surfaces have block solid reinforcements which, in turn, are configured in such a way as to economize material. These - called trestles to the lower part of the CTFerpcT - The drive shaft is disposed of such that different mounting positions of the door lock can be realized. Likewise, the tree is housed and fixed in the corresponding axial bore, in a manner that is considerably economical in terms of material and easy to assemble. The reduction of external dimensions decreases the amount of packaging materials required and reduces the storage and transport space. The reduction in volume and weight increases the density of packaging during transport and also facilitates on-site handling by assembly personnel. Likewise, the mentioned properties contribute considerably to the reduction of manufacturing costs. - Next, the invention is illustrated with the help of exemplary embodiments, with reference to the drawings. They show: Figure 1, a perspective view of a door lock. - - Figure 2, a front view of the door lock according to Figure 1. Figure 3, a bottom view of the door lock according to Figure 1. Figure 4, a vertical longitudinal section of the lock of door according to Figure 1. Figure 5, a vertical longitudinal section of the door lock according to Figure 1. Figure,, a perspective view of a second embodiment of a door lock. Figure 7, a front view of the door lock according to Figure 4. Figure 8, a perspective view of a third embodiment of a door lock. Figure 9, a front view of the door lock according to Figure ß. In the figures, the identical components or of the same functions, are indicated with the same references. The door locks 1 shown in the figures are manufactured in one piece in a casting process and consist, for example, of aluminum or steel. Despite the aspect of optimizing the minimum consumption of material with sufficient stability of the body, a solid body is not obtained- "1. In principle, all external contours and transitions ^ of ^ surface are rounded. they are equipped to house respectively a mechanical and a hydraulic operating unit, which, in order to reduce the construction height, are arranged in a known manner in a channel 21 in a longitudinal extension of the body 2. A shaft 22 connects the mechanical unit in the body 2 with a linkage outside it The shaft 22 leaves on both sides of the body 2, so as to be able to variably manage the arrangement of the door lock 1 and the linkage in relation to a leaf and a door frame, depending on For the sake of clarity, the linkage is not shown In the elongate body 2, a plunger 23 and a closing spring 24 are coupled between if in a displaceable way. The shaft 22 is rotatably received in the body 2 and has a gear 25 in the center, which acts together with a rack 26 formed in one piece inside the plunger 23. The shaft 22 is coupled outside the body 2 with the linkage not shown When the door is opened, the shaft 22 rotates on the linkage engaged with the door The plunger 23 moves in the horizontal direction and compresses the closing spring 24. As soon as the door is released, the stored opening energy it is released again, the closing spring 24 expanding and pressing the piston 23 in the opposite direction.With the conversion of the linear movement in a rotary movement, the door is closed again In the body 2 there is hydraulic oil as agent The body 2 has an axially oriented shaft bore 27 for receiving and holding the shaft 22. The shaft bore 27 has a round cross-section. Figure 5 upper part of the shaft bore 27 has an edge 28 that narrows in its cross section. The bottom of the. The shaft bore 27 has a groove 29 for a sealing ring 30. The shaft 22 is configured symmetrically and has the gear 25 in the center 25. On both sides of the gear 25, discs 31 are previously mounted. At both ends of the shaft 22 are formed devices to fix a linkage. East, depending on the installation situation, it is mounted at the appropriate end. On both sides of the shaft 22, the so-called sintered bushes 32, 37 of ceramic material serve as housing. A tubular housing 33 has a graduated cross-section, which opens into a ridge 34. The external surface of the housing basin 33 is increased radially, at least in zones. The assembly of the door lock 1 is described below. The housing bowl 33 forms a preassembled unit, in which first an annular seal 35 is inserted against the edge 34 and subsequently the sintered bushing 32 is pressed against the seal ring 35, so that it can not be released In the upper part of the shaft bore 27, an annular seal 36 and then the sintered bushing 37 are fixed in a non-removable manner. At the bottom of the shaft bore 27, the sealing ring 27 is inserted. The shaft 22 slides into the upper part of the shaft bores 27, through the sintered shaft 37 there sanding, until it hits the disk 31 against the channel 21. The assembly and the integral support of the shaft 22 are effected by placing the housing bowl 33 in the lower part of the shaft bore 27. The pre-assembled housing bowl 33 slides on the shaft 22 and is placed with a pressure defined definitively in the body 2 and on the shaft 22. At the beginning, the sintered shaft 32 slides on the shaft 22 and the outer surfaces of the housing 33, along the internal wall of the perforation axis 27. The housing bowl 33 amplified in zones, preferably by a projection, elastically presses out the body 2 surrounding the shaft bore 27. After passing through the groove 29, the projection engages therein due to the elastic recovery of the body 2 and the housing bowl 33 is fixed. Simultaneously, the shaft 22 is also in the axial position due to the contact of the sintered bushing 32 with the disk 31. "In principle, the body 2 is elongated, it has an upper surface 3 with respect to a lower side 4. In In this case, mounting plates 9, 10 are formed in longitudinal extension, which serve to fix the body 2 to a door leaf or frame, The lower side 4 and the upper surface 3 are joined in longitudinal extension by lateral surfaces 5, 6. The front sides 7, 8 are arranged perpendicular to the side surfaces 5, 6 and the lower side 4 and the upper surface 3 and delimit the body 2 in longitudinal extension The mounting plates 9, 10 protrude from the body 2 on the sides front 7, 8. The exemplary embodiment according to Figures 1 to 3 has the following features: The side surfaces 5, 6 extend starting on the bottom side 4 with a curved Atura directed to the interior of the body, and end in the upper surface 3. The curvature presents a parabolic course, delimiting the upper surface 3 said course. The transitions between the lateral surfaces 5, 6 and the upper surface 3 are formed by small radii. The shaft is housed in the center between the upper surface 3 and the lower side 4, and outside the center between the front sides 7, 8. This arrangement of the shaft 22 allows various mounting variants, for example, of inverted image, the door lock 1. It protrudes in both side surfaces 5, 6 of the body ~ ^ 2, in "the trestles 11, 12. These are solid and are formed in one piece in the body 2, to ensure a stable accommodation of the shaft. The trestles 11, 12 have respectively trapezoid-shaped formal surfaces 13, 14 which extend perpendicularly to the lower side 4, the wide bases 15, 16 being placed on it.This trapezoidal cross-section of the trestles 1112 extends slightly increased from the front surfaces 13, 14 to the side surfaces 5, 6. The trestles 11, 12 have such dimensions that they do not protrude from the upper surface 3. In Figures 6 and 7 a body 2 is shown. , whose side surfaces 5, 6 also run in a parabolic manner. The upper surface 3"is slightly curved outwards from the body, so that the additional casting material can be saved The transitions between the side surfaces 5, 6 and the upper surfaces 3 are also formed with small radii. 11, 12 have front surfaces 13, 14 in a "U" shape, with the open sides 17, 18 on the lower side 4. The "U" -shaped cross section of the stands 11, 12 is slightly amplified in the direction of the side surfaces 5, 6. For reasons of material economy, the mounting plates 9, 10 are configured in a beveled manner, and in Figures 8 and 9 there is shown a body 2, whose side surfaces 5, 6 have various curvatures. The lateral surface 5 extends in a parabolic manner, as already described in the exemplary embodiment according to FIGS. 1 to 3, and abuts a flat upper surface 3. The lateral surface 6 has a different course from that of FIG. l parabolic with respect to the lateral surface 5, which is characterized, because the lateral surface 6 passes without transition to the upper surface 3. This, therefore, is one side flat and the other bulging. The three examples of embodiment have in common that in the lower side 4 they have two perforations 19, 20, as seen in Figure 3. Said perforations 19, 20, during the manufacture according to the casting process, serve to center and fix the piece to other processing equipment. In this way, especially in the production with machinery, incorrect positioning of the workpiece can not occur. - " References 1 Door lock 20 Drilling 2 Body 21 Channel 3 Top surface 22 Tree 4 Bottom side 23 Plunger 5 Lateral surface 24 Closed spring 6 Side surface 25 Gearing ~ 7 Front surface 26 Zipper "- 8 Front surface 27 Shaft drilling 9 Mounting plate 28 Edge 10 Mounting plate 29 Slot - 11 Trestle 30 Sealing ring: 12 Trestle 31 Disco- _ ^ _ _ 13 Front surface 32 Sintered bushing 14 Front surface 33 Accommodation bowl Base 34 Edge 16 Base 35 Ring plug 17 Open side 36 Obturation ^ annular 18 Open side 37 Sintered bushings 19 .Perforation
