Definitions
- the invention relates to a door for a separable interior, in particular for a freezer compartment arranged in a refrigerator, according to the preamble of claim 1.
- Locking devices for such freezer doors must meet certain requirements. Thus, the door must be opened by simply pulling on a handle. Once the frozen food has been removed, the door must be re-closable with the free hand. It should not matter whether the free hand on the handle or elsewhere presses on the door to let the locking device engage again.
- a known locking device of this type has a handle, a locking hook and a spring element for returning the handle.
- the locking hook is integrally connected to the spring element. This part is mounted on the handle so that it is pivotable relative to this about an axis.
- the handle is then attached to the freezer compartment door in such a way that the spring element is supported on the door. If the handle is now actuated, the locking hook pivots back so far that the locking block is released to the freezer and the door can be opened. Once the handle is released, the locking hook and a stop as well as the handle of the spring element is pushed back to its original position.
- the locking hook is pushed back by the locking block on the freezer compartment. As soon as the closing hook has passed the closing bolt, it is pressed by the spring element back into its closed position.
- This known freezer compartment door consists of a larger number of parts that have to be manufactured individually. To finish the freezer compartment door then a considerable installation effort is still necessary.
- the invention has for its object to reduce the production cost of such a freezer compartment door. In particular, the number of necessary parts should be reduced. At the same time, the assembly effort should decrease.
- the object is achieved according to the invention by a door for a separable interior with the features of claim 1. Due to the one-piece design of the entire closing device only a single production step is required for this. The assembly work for the locking device is completely eliminated. Since the locking device already contains all the necessary parts, such as handle, locking hook and spring element, the locking device only has to be mounted on the door.
- the one-piece design of the locking device also all problems are avoided, which can arise during the assembly of several items. These include manufacturing tolerances of the individual parts, but also malfunctions that can occur when using different materials for the individual parts in temperature changes.
- the locking device therefore has a handle, a locking hook and a spring element for returning the handle. Thus, all elements are present in the one-piece locking device, which are necessary for the closing function.
- connecting elements are provided which allow a pivoting movement relative to the door.
- the connecting elements provided on the closing device can be designed, for example, as bearing lugs.
- a side part On one side of the handle, a side part is mounted approximately at 90.degree .. To fix this angle, the connecting elements are each connected in the edge region of the handle to the locking device so that they have a firm connection with the handle and on their one side On the other side, a firm connection with the side part is received, thereby preventing a pivotal movement of the side part relative to the handle.
- the locking hook of the locking device has a base, with which it is connected to the handle. Furthermore, this locking hook on a locking leg, with which he engages behind the locking block, for example, a freezer compartment.
- the base of the closing hook is advantageously formed by two cuts in the side part. About the depth of these incisions, the force can be dimensioned with which the locking leg is held in its rest position. In this way arises between the handle and the locking hook a flexible connection, via which the locking hook can be pivoted against the handle.
- the width of the incisions should be chosen so that a hooking of the locking leg is not possible on the side panels.
- the spring element which is advantageously shaped in the manner of a strap, is connected to each strap end in each case with one of the side parts on both sides of the closing hook. Since the side parts take over the connecting elements a fixed position relative to the handle, and the attachment points of the spring element relative to the handle are fixed.
- the contact between spring element and door must be precisely defined.
- a bevel is provided on the spring element, which is designed so that it runs approximately parallel to the corresponding contact surface on the door. This avoids that touch the spring element and the door only at one point, with this contact point could easily move during the movement of the handle and it could even come in extreme cases to a deadlock between the spring part and door.
- the closing device is injection molded from plastic.
- grip, spring element and locking hooks consist of only one material, so that no malfunctions are to be expected even with larger temperature changes.
- Fig. 1 is a 3D view of the closing device of the door according to the invention in the
- Fig. 2 is a section through the locking device.
- Figure 1 shows a 3-D view of a closure device 1 in the bottom view as seen in doors for closing box-type freezers, e.g. in household refrigerators, are used.
- This locking device 1 is thus part of a door not visible in this illustration.
- the locking device 1 has a closing hook 2, a handle 4 pivotable for its operation, a left side part 5 and a right side part 6. Between the side parts 5, 6 recesses 3 are provided.
- the handle 4 is designed as a non-aselant angle profile, the long leg is located above a mounted on the front of the door not visible here recessed grip and forms the actual handle.
- the short leg is divided into three parts and consists of the already mentioned closing hook 2 and the two side parts 5 and 6.
- the locking hook 2 takes up almost half of the entire leg length.
- the left side part 5 and the right side part 6 are located on the left of the closing hook 2.
- the left side part 5 and the right side part 6 are each separated from the closing hook 2 by a recess 3 and end flush with the handle 4.
- the two cutouts Gen 3 are wide enough to exclude a hanging in the fixed side parts 5, 6 at a pivoting of the closing hook 2.
- the depth of the recesses 3 determines on the one hand, that the locking hook 2, which is an integral part of the locking device 1, sufficient elasticity in the vertical direction to rut on the non-visible in this view, attached to the freezer lock to see rut when the door is closed without pressing the handle 4 and on the other hand, that the locking hook 2 reliably locked with the door closed with the locking pin.
- the locking device 1 further comprises a left support 7 and a right support 8, each with a bore 9, an edge 10 and a spring 1 1 with a left end 12, a right end 13, a middle part 14 and two legs 15.
- the left support 7 is perpendicular to the handle 4 and the left side part 5 and is firmly connected to these two parts.
- the right-hand support 8 is at right angles to the handle 4 and the right side part 6 and is also firmly connected to these two parts.
- the left support 7 and the right support 8 thus also act as stabilizing elements which fix the angle between the handle 4 and the side parts 5, 6.
- the left support 7 and the right support 8 each have a cylindrical bore 9, in which not visible in this illustration pin, which are part of the door, engage. About the interaction pin - bore 9, the pivoting of the handle 4 is ensured relative to the door. The position of the bore 9 in the left support 7 and the right support 8 is placed so that the bore edge just touches the inner sides of the handle 4 and the left side part 5 and the right side part 6 and so ensures compact dimensions.
- edge 10 runs on the inside of the handle 4, the edge 10 runs. This edge 10 starts or ends at the level of the left support 7 and the right support 8, respectively.
- the spring 1 1 has a symmetrical to the middle triple-curved shape.
- the left end of the spring 12 is firmly connected to the left side part 5 and the right end of the spring 13 fixed to the right side part 6.
- This spring middle part 14 is supported with its front portion 17 (see FIG. 2) on the door, which is not visible in this illustration, and causes the handle 4, after its intended use, to fit back into the door Starting position is pushed back.
- the necessary spring force is generated by the two spring legs 15 which are biased by the pivoting of the locking device.
- the peculiarity of the locking device 1 is, inter alia, that it is a cost-manufacturable injection molded part made of elastic material. Due to the choice of material, the molded-on closing hook 2 and the molded-on spring 1 1 can fulfill their function.
- the locking device 1 is formed in one piece so that the assembly days can be carried out inexpensively.
- FIG. 2 shows a detailed view of the closing hook and the spring.
- This sectional drawing of the locking device 1 shows the locking hook 2 with a closing 16 and a bevel 18, the handle 4, the left support 7 with the bore 9 and the spring 1 1 with its spring center part 14 and the front portion 17.
- the lock hook 2 has a Z-shape, in which the locking leg 16 slightly downward points, in order to be able to form a good fit with the locking block of the freezer compartment.
- This has the advantage that the closing device 1 always remains reliably closed due to the undercut between the locking leg 16 and the locking pin, not shown.
- the angle of the locking leg 16 is selected so that in the closed state, the locking device 1 can pivot without increased effort or additional pressing of the door.
- the locking leg has on the top of the slope 18, which serves to push back the closing hook 2 when the door is pressed while the locking leg 16 slides over the locking block of the freezer compartment.
- the spring 1 1 is at an acute angle to the handle 4.
- the front portion 17 of the spring center portion 14, with which the spring center portion 14 is supported on the non-visible door, is shaped so that the spring 1 1 is supported flat on the door.
- the door is opened by the closing leg 16 of the locking hook 2 is pivoted so far from the locking block of the freezer by pulling on the handle 4, until the locking leg 16 releases the locking block.
- pivoting the spring 1 1 is additionally tensioned, since the distance between the side parts 5, 6 and the spring 1 1 is reduced by the rotational movement about the bore 9 at the level of the spring center part 14. This spring preload serves to reset the closing device 1 after opening into its initial position.
- the door can be closed in two different ways. On the one hand, the door can be pressed without actuating the closing device 1. In this case, the locking leg 16 is pushed back by the interaction closing cam - slope 18 until it slips over the locking block. Due to the elasticity of the material, the closing leg 16 is then pressed into the closed position.
- the door can also be closed by pulling the handle 4 until the stop of the locking leg 16 is pulled back so far that it fits without touching the locking pin. Now the door is brought into its closed position. Since here too the spring 1 1 was biased in the manner described above. de, the release of the handle 4 causes the locking device is pressed into its original position. In this case, the closing leg 16 is pressed into the closed position.
