Definitions
- the invention relates to a rotary latch lock for cabin doors of construction vehicles and tractors or similar devices with an angular bearing element, which has a cuff leg and a lock plate leg, with a fork latch with a bearing bush rotatable on the one side and a pawl and over on the other side the pawl rotatably mount a release element with a further bearing bush and the bearing bushes are riveted into bores located in the cuff leg and each have a through-hole, on the lock plate leg a handle lever protruding from the housing is pivoted and an opening in the lock plate leg and a receiving slot for one Locking bolts are introduced and spring elements are provided which act on the handle lever as well as the fork latch and the pawl.
- Cabin doors must meet different conditions than locks for cars or trucks. In the context of a door of such motor vehicles, there is a great deal of space for accommodating a lock, so that the structure of the locks can be constructed in a correspondingly large and large manner. Large-scale and large-scale designs require a sufficient degree of functional reliability and stability.
- the conditions in cabins are different. Cabins consist of thin and lightest possible wall elements. The doors are correspondingly thin. The locks that are used for cabin doors must be spatially narrow and small, but still ensure high strength.
- a so-called relining made of sheet steel parts is used because the components of the door elements for storing a lock are not sufficiently rigid and strong.
- the components for the relining are relatively expensive to manufacture in the known cabin locks and their attachment also requires too much time.
- the object of the invention is to provide a simplified, less individual cabin lock of high strength and with an increased closing distance between the pre-and final locking position, which also requires little time for installation and for which a simple relining can be used.
- the bearing element consists of a right-angled angle plate with two legs forming the cuff leg and the lock plate leg, the angle plate consisting of a plate with a thickness of at least 3 mm, and with a rectangular plate as the relining Through holes of the bearing bushing bolts are fastened on the end of the bearing bushing opposite the riveting.
- the thick and therefore torsionally rigid angular plate can be used as the relining for the simple, rectangular plate with a thickness of, for example, 4 mm, which is particularly advantageous in view of the fact that the object of the application is a mass article. which is much cheaper to manufacture due to the design according to the invention.
- the construction of the new rotary latch lock has an angle plate 1 with a cuff leg 2 and a lock plate leg 3 arranged at right angles to it.
- a cover 4 can be placed against the angle plate 1 (FIG. 1), which is preferably made of plastic, and a top wall 5 to complement the walls formed by the legs 2 and 3 of the angle plate 1 , has two side walls 6 and a front wall 7. Holes 8 and 9 are provided in the ceiling wall 5, the task of which is explained below.
- the angle plate 1 has an essentially rectangular opening 10 in the lock plate leg 3 in the area above the kink edge 11, which merges into an initially funnel-shaped receiving slot 12 in the cuff leg 2.
- the opening 10 and the slot 12 form in a manner known per se the latch opening of the lock for a locking bolt 13 which, with the other lock parts, ensures a locking a car door interacts, the lock being fastened to a frame 14 of a car door 15 (FIG. 6) and the locking bolt 13 to the frame of the car (not shown), for example with a relining plate 17, or vice versa.
- the height of the opening 10 depends on the length of the locking bolt 13, and the width of the receiving slot 12 corresponds to the diameter of the locking bolt 13 in the latching region 12a adjoining the funnel region, in which the slot edges run parallel, so that the latter is approximately form-fitting Locking area 12a can slide.
- the arrangement of the lock parts to be described is such that a relatively long and wide receiving slot can be provided. There is also enough space in the interior of the castle that a relatively long locking bolt 13 can be guided through a high opening 10. Accordingly, a thick and robust, long locking bolt can be used, which results in a high locking strength. In addition, a relatively large game of the fit between the door and the cabin can be tolerated because the locking bolt 13 and the opening 10 and the receiving slot 12 are large. Furthermore, in combination with the spatial shape and arrangement of the individual parts of the lock to be described, such a long receiving slot 12 can be used that a relatively long closing path between the pre-locking and final locking positions of e.g. 10 mm can be used.
- the formation of the bearing carrying the lock parts in the form of a simple angle plate 1 also requires that a thick plate can be used because, apart from a simple 90 ° bend, no further shaping processes are required. Sheet thicknesses of preferably 3 mm and more are possible.
- a thick sheet is torsion-resistant and offers the further advantage that only two attachment points need to be provided to attach the lock to the relining.
- the thick, torsion-resistant sheet metal also has the advantage that a simple, rectangular sheet metal 17, for example 4 mm thick, can be used as the relining.
- the fork latch 18, the pawl 19 and the release lever 20 for actuating the lock are rotatably mounted on the cuff leg 2 from the outside.
- the lock plate leg 3 rotatably supports an inside handle lever 21 and preferably also a safety catch 22.
- the cuff leg 2 has the two transverse side edges 2a and 2b and the longitudinal side edge 2c.
- the slot 12 extends over the longitudinal center line (not shown) of the cuff leg 2 running parallel to the longitudinal side edge 2c and is located between the transverse side edge 2b and the transverse center line (not shown) of the cuff leg 2 running parallel to the transverse side edge 2b.
- a vertical bearing bush 23 which has a through bore 23a. It is riveted in a manner known per se into a hole (not shown) in the cuff leg 2.
- the bearing bush 23 serves as a rotary bearing for the fork latch 18, an annular groove directed radially to the bore 23a being introduced into the jacket of the bearing bush 23, the bottom of which positively engages through a bearing bore introduced into the fork latch 18, so that the fork latch 18 is rotatable about a perpendicular to the Level of the cuff leg 2 lying axis is mounted.
- the bearing bush 25 which also has a through hole 25a, supports the pawl 19 and the release lever 20, an annular groove 26 being provided which receives both parts in a form-fitting manner by the pawl 19 being arranged under the release lever 20.
- Fig. 6 shows this known storage.
- the fork latch 18 has two fork arms 27 and 28 and a fork arm base 29. Between the fork arms 27 and 28 there is the fork latch slot 30, the shape and length of which is dimensioned such that it can positively engage around the locking bolt 13.
- the mounting of the fork latch is such that the fork latch slot 30 points in the direction of the receiving slot 12 and the length of the fork arms 27, 28 is such that they protrude beyond the receiving slot 12 in the closed position (FIG. 3), so that the latching area 12a of the Receiving slot 12 and the end portion of the fork arms form a closed passage by the locking bolt 13 is caught.
- the fork arm 27 is so long that its outer edge 27a abuts the inner edge 10a of the opening 10 in the free end region when the fork latch is in the starting position (FIG. 2).
- the outer edge 27a preferably has a step-shaped recess 27b as the end region and likewise the edge 10a has a step-shaped recess 10b as the free end region, so that the edges of the recesses 27b and 10b interact as stops (FIG. 2).
- the inner edge 27c of the fork arm 27 expediently begins to be chamfered in a funnel shape, so that it runs approximately flush with the funnel-shaped inlet edge of the receiving slot 12 in the starting position of the fork latch (FIG. 2).
- the fork arm 28 also has a funnel-shaped bevel 28c in the initial area on the inner edge of the fork latch slot 30, which functions as the end catch edge.
- a stepped locking recess 28b with a pre-locking edge 28d is made on the outer edge 28a in the free end region, which in combination with the bevel 28c results in a rounded tip 28e.
- the other edge 28f of the locking recess 28b is somewhat spherical or arcuate as a sliding edge and interacts with the pawl 19.
- a vertically standing mandrel 31 is arranged on the fork latch base 29, which serves to mount one end of a tension spring 32.
- the dimensions of the fork latch base 29 are designed such that the outer edges do not overlap the edges 2b and 2c of the cuff leg 2 when the fork latch is pivoted.
- a narrow actuating web 19b extends up to just before the folding edge, which is integrally attached to the disk of the pawl 19.
- the inner edge 19a of the pawl 19 adjacent to the receiving slot 12 has an approximately triangular, projecting locking lug 19c, the front edge 19d of which acts as a sliding edge and the rear edge 19e of which acts as a locking edge, as will be described.
- the rear edge 19e of the locking lug 19c merges into an outwardly jumping straight stop edge 19f which, in the basic position of the pawl (FIGS. 2, 3), abuts against a stop mandrel 33 arranged vertically on the cuff leg 2 in the region of the longitudinal side edge 2c and the transverse center line.
- the back edge 19g and the outer edge 19h of the pawl 19 are rounded, so that in particular the back edge 19g does not protrude beyond the longitudinal side edge 2c of the cuff leg 2 when the pawl 19 is pivoted.
- a vertically standing driving mandrel 34 is arranged on the pawl 19 in the region of the back edge 19g, which supports the other end of the tension spring 32 and, as will be described later, cooperates with the release lever 20.
- the tension spring 32 is positioned so that in the starting position of the lock it presses the edge 27b of the fork latch 18 against the edge 10b of the lock plate 3 and the stop edge 19f against the stop pin 33.
- the fork latch 18 and the pawl 19 move against the tensile force of the tension spring 32.
- the release lever 20 which is rotatably mounted above the pawl 19 and independently of the latter, and which is described below with reference to FIG. 4, has a disk-shaped base body 20a.
- a radially outwardly projecting driving lug 20b is attached in one piece, the rear edge 20d of which rests on the driving mandrel 34, and the outer edge 20c of which is flush with the stop edge 19f of the pawl 19, so that the outer edge 20c against the stop mandrel 33 can encounter when the trigger lever 20 is in the starting position (Fig. 2, 3).
- a lever web 20g on the disc 20a facing the transverse side edge 2a of the cuff leg 2 is arranged in one piece, on the end area of which there is a securing lug 20e extending in the direction of the kinked edge 11 and on which a release web 20f which is bent vertically upwards is also in the End area is arranged.
- An essential part of the handle lever 21 is a lever web 21 a, which is pivotable about an axis 35 lying perpendicular to the plane of the lock plate 3 on the lock plate 3 next to the recess 10, namely on the side of the recess 10 opposite the edge 10a .
- the web 21 a forms a lever, the lever arm 21 b projecting outward beyond the lock plate 3 and the lever arm 21 c pointing in the direction of the folding edge 11.
- the locking pawl 22 (FIG. 5) is located behind the handle lever 21 and is pivotally mounted on the lock plate 3 about an axis 36 lying perpendicular to the plane of the lock plate 3.
- the axes 35 and 36 lie approximately at the same height in the area of the longitudinal side edge 3b of the lock plate 3.
- the locking pawl 22 extends from the axis 36 in the direction of the folding edge 11. It has a triangular notch 22b on the front edge 22a, the lower edge 22c of which as a locking edge works. This locking edge 22c extends approximately from the edge 22a in the direction of the longitudinal center of the locking pawl 22.
- the locking pawl is beveled in the direction of the rear edge 22d, which results in a sliding edge 22e.
- This sliding edge 22e interacts with the lower corner region 21 of the handle lever 21 and the latching edge 22c with the free lower edge 21f of the handle lever 21, as will be described.
- a vertical bearing mandrel 37 which supports one end of a tension spring 38.
- the other end of the tension spring 38 is supported on a vertically projecting stop pin 39 which is arranged in the lower end region of the locking pawl 22 and interacts with the locking lug 20e of the release lever 20.
- the function of the lock described corresponds to the function of the known lock.
- the release lever 20 is operated and moved in the direction of arrow 40 (FIG. 4).
- the nose 20b takes the mandrel 34 and thus the pawl 19 with it until the edge 28c or the nose 28e slides over the nose 19c.
- the fork latch pivots under the tensile force of the tension spring 32 in the direction of arrow 41 into the starting position.
- the same can be done with the pivoting of the handle lever 21 in Direction of arrow 42 are effected because the nose 21e e pivots the pawl 19 via the web 19b accordingly.
- a stop - in this example the front edge 22a of the locking pawl 22 - ensures that the handle lever 21 cannot be pivoted too far in the direction of arrow 42 and disengages from the web 19b.
- the locking pawl 22 is provided. This is pivoted with the handle lever 21 into the position shown in FIG. 5 by the handle lever 21 being pivoted in the direction of arrow 43.
- the corner 21g of the handle lever 21 slides on the slope 22e until the lower edge 21f slides into the recess 22b and the edges 21f and 22c abut each other. This takes place against the tensile force of the tension spring 38.
- the position of the securing dome 39 is such that when the release lever 22 moves in the direction of the arrow 40 the nose 20e abuts the securing pin 39 and the pivoting is thus limited. This pivoting is not yet so extensive that the fork latch slips out of the lock.
- FIG. 6 also shows that a push button 47 which is arranged in a door handle 46 and is known per se in its function can be provided, which pushes through the cabin trim 15 and acts on the release lever 20.
- the handle lever 21 is located inside the cabin. Its pivoting in the direction of arrow 43 secures the lock against opening from the outside.
- the push button 47 can be turned in such a way that its web 47a which interacts with the release lever 20 is pivoted away from the release lever 20.
- the holes 8 and 9 in the top wall 5 of the cover 4 serve for the handle lever 21 and the trigger bar 20f to reach through.
- the cover 4 is held only by the fact that the bearing bushes 23 and 25 have at least one annular groove on their outer jacket, e.g. Wear 23 b, into which latching spring arms 5a, which project inward on the ceiling wall 5, are latched with corresponding latches 5b.
- cover 4 provides that the cover is made lower than the height of the lock leg 3, holes 23 and 25 being made in the ceiling wall 5 in the area of the bearing bushes 23 and extending from the end region of the bearing bushes 23 and 25 are penetrated, whereby the edge of the hole is snapped into the ring groove (eg 23b).
- This embodiment of the cover 4 allows the relining sheet 17 to be screwed on from the outside over the cover. If the cover 4 has the full height of the lock leg 3, as shown in FIG. 1, a corresponding slot is provided in the front wall 7 for the relining plate 17.
- the relining sheet 17 extends with its width from one bearing bush 23 to the other bearing bush 25, so that the function of the release lever 20 is not impaired.
- a separate stop for the pawl 22 which ensures that the pawl is not pivoted by the action of the tension spring 38 when the lever 21 is pivoted in the direction of arrow 42.
- the stop should act so that the pawl 22 remains in its position shown in Fig. 4 and the tension spring 38 is stretched so that the lever 21 pivots against the force of the spring 38 and after pivoting by the tension of the spring 38 back into swings back its starting position.
- a disc 35a is therefore used as the stop, which is arranged on the surface of the lever 21, preferably lying with its center in the axis 35. This disc 35a (Fig.
