Abstract
Description
- This application is a first-filed application and, therefore, does not rely on any other application for priority.
- 1. Field of the Invention
- The present invention relates to a guiding rail for a cabinet pull-out part, such as a drawer. More specifically, the present invention relates to a cabinet pull-out part with a carcass rail, which can be fixed to a cabinet carcass, a running rail, which can be fixed to the drawer part, and a pull-out, extending, center rail arranged between the carcass rail and the running rail. Even more specifically, the present invention relates to a cabinet pull-out part including a blocking device where the guiding rail can be mechanically locked in the completely pushed-together state as well as in the fully extended state.
- 2. Related Art
- Guiding rails are known per se.
- Particularly, when such guiding rails are used in the case of heavy drawer parts and/or when corresponding guiding rails are used under conditions in which a horizontal orientation of the guiding rails is not always guaranteed, for example, in airplanes, ships, travel buses or the like, it is required for safety-related reasons to equip such guiding rails with blocking devices. These blocking devices provide that, in the closed state, as well as in a completely open state, the drawer parts are secured against an unintended displacement, so that the risk of an unintended opening as well as an unintended closing as a result of the force of gravity is virtually avoided.
- In the case of the known guiding rails of this type, the blocking devices are designed such that they respond to the exercising of force in the displacement direction of the individual components of the guiding rail. This means that, when a corresponding drawer is opened, an increased expenditure of force is first required in order to overcome the blocking of the closed position. Likewise, from the opened and blocked position, an increased expenditure of force is first necessary for eliminating this blocking and for being able to displace the drawer into its closed position.
- However, particularly when the drawer is fully open, in the case of previous constructions, the blocking device may also be released by an unintended pushing against the drawer part.
- A need exists, therefore, for guiding rails for drawers that provide securement against unintended opening or closing as a result of the force or gravity or as a result of unintended pulling on or pushing against the drawer part.
- It is an aspect of the present invention, therefore, to address at least some of the above-noted needs with respect to guiding rails and drawers.
- As a result, it is one aspect of the present invention to provide a guiding rail of the above-mentioned type where a blocking device can be unlocked in both displacement directions without any significant expenditure of force and without the risk that the blocking device can be triggered by involuntary or faulty operations.
- According to the invention, this aspect can be achieved by providing a blocking device that includes a rod which extends in the longitudinal direction of the running rail, is disposed in this running rail, can be rotated about its longitudinal axis, and has at least one snap-in tooth projecting transversely to the longitudinal axis. The blocking device is further provided with a spring-loaded notch lever swivellably disposed at a rearward end of the center rail, which engages when the guiding rail is completely pushed together. The at least one snap-in tooth engages in a corresponding opening of the carcass rail and, when the guiding rail is completely pulled out, rests against the forward face of the center rail. The rod is spring-loaded such that the at least one snap-in tooth is constantly loaded in the direction of the carcass rail and, when the guiding rail is fully pulled-out, the notch lever engages with at least one snap-in projection in a blocking manner in a recess of the carcass rail and is movable out of the blocking position by a lug fastened to the rearward end of the running rail.
- A guiding rail conceived in this manner is blocked by form-locking interacting devices in its two possible end positions (i.e., opened or extended and closed or collapsed). In the case of a blocking in the fully pushed-together state (i.e., when the drawer is closed), these devices include the at least one snap-in tooth, which engages in the opening of the carcass rail. In the fully pulled-out state (i.e., when the drawer is fully opened), a form-locking blocking is also achieved, on the one hand, by means of the at least snap-in projection of the notch lever which engages in a recess of the carcass rail and, thereby, blocks the center rail with respect to the carcass rail. In the fully pulled-out state, the form-locking blocking also is achieved as a result of the at least one snap-in tooth which, in the fully pulled-out state of the guiding rail, rests against the forward face edge of the center rail.
- When the guiding rail is to be extended from its pushed-together state or is to be collapsed from its extended state, an operation of the rod with the at least one snap-in tooth is necessary in both cases. Operation of the rod with the at least one snap-in tooth moves the at least one snap-in tooth either out of the recess of the carcass rail or swivels the at least one snap-in tooth out of the face side area of the center rail. In either case, once the snap-in tooth has been disengaged from the corresponding locking structure, movement of the guiding rail becomes possible. After disengagement of the at least one snap-in tooth, for the longitudinal displacement of the guiding rail, in the pull-out direction as well as in the push-in direction, only the internal frictional forces have to be overcome, but no additional forces have to be applied for eliminating the blocking.

- In the drawings,
reference number 1 indicates a guiding rail for a cabinet drawer part, which is not shown. The cabinet drawer part may be a drawer, shelf, or other structure suitable for supporting or containing one or more predetermined articles thereon or therein. As illustrated inFIG. 2 , the guidingrail 1 includes acarcass rail 2 fixable to a cabinet carcass, a runningrail 3 connectable with a drawer part, and a drawer-extendingcenter rail 4 arranged between thecarcass rail 2 and the runningrail 3. The runningrail 3 is telescopically slidable within thecenter rail 4, which is telescopically slidable within thecarcass rail 2. This telescopic arrangement is illustrated, for example, inFIG. 6 . - In the fully pushed-together condition, as shown in
FIGS. 1 to 4 , the guidingrail 1 is blocked. The term “blocked,” as used herein is intended to refer to a condition where the guiding rail may not be extended or compressed by gravity or by an unintended action, such as bumping by an individual. This means that the runningrail 3 and thecenter rail 4 cannot be displaced with respect to thecarcass rail 2. This blocking is achieved by arod 5 which is mounted in the runningrail 3 and has two snap-inteeth 6 which engage incorresponding openings 7 in thecarcass rail 2, as illustrated particularly inFIGS. 1 , 3 and 5. - As illustrated particularly in
FIG. 9 , therod 5 is rotatably disposed inside the runningrail 3 by way of two bearing blocks 8 and 9, which can be screwed or otherwise fixed to the runningrail 3. Therod 5 also is secured against an axial displacement by the two bearing blocks 8 and 9. At the end protruding beyond the forward end of the runningrail 3, therod 5 is equipped with ahandle 10 extending at an angle with respect to the longitudinal axis of therod 5. - By means of a
spring 11 acting upon one of the snap-inteeth 6, as clearly illustrated inFIG. 5 , therod 5 is acted upon by a torque, by which the snap-inteeth 6 are constantly rotated in the direction of thecarcass rail 2. This means that the snap-inteeth 6 snap into the above-mentionedopenings 7 of thecarcass rail 2 when therod 5 is not operated by a user by way of thehandle 10 against the loading direction of thespring 11. In other words, to disengage the snap-inteeth 6 from thecarcass rail 2, a user must rotate thehandle 10 to overcome the spring force applied by thespring 11. - When the snap-in
teeth 6 engage theopening 7 in thecarcass rail 2, the above-mentioned blocking of the guidingrail 1 is ensured, because the runningrail 3 cannot be displaced with respect to thecarcass rail 2 in its longitudinal direction. Only when a user swivels or rotates therod 5, by gripping and rotating thehandle 10 oppositely to the direction of the force applied by thespring 11, to a rotational point where the snap-inteeth 6 are swiveled out of theopenings 7, can the runningrail 3 be displaced with respect to thecarcass rail 2 in the longitudinal direction or in the pull-out direction, for example. - In the fully pulled-out condition of the guiding
rail 1, as illustrated inFIGS. 6 and 7 , when therod 5 is not swiveled or rotated by a user, one of the snap-inteeth 6 is situated in front of the face-side forwardend 4 a of thecenter rail 4. This is clearly visible inFIG. 7 . -
FIG. 6 shows that, at the rearward end of thecenter rail 4, anotch lever 12 is swivelably disposed on thecenter rail 4 and is loaded by aspring 13 such that the snap-inprojections 14 of thenotch lever 12 are constantly loaded in the direction of thecarcass rail 2. In the fully pulled-out condition, the snap-inprojections 14 engage inrecesses 15 of thecarcass rail 2. By this operation, when the guidingrail 1 is completely pulled out, as illustrated inFIG. 6 , thecenter rail 4 is mechanically blocked with respect to thecarcass rail 2. - An
operating lug 3 a is fastened to the rearward end of the runningrail 3. Theoperating lug 3 a, when the guidingrail 1 is moved into the closing position, moves under an operatingnose 12 a of thenotch lever 12 and moves thisnotch lever 12 out of therecesses 15 of thecarcass rail 2 against the action of thespring 13. As a result, thecenter rail 4 is unlocked with respect to thecarcass rail 2 and, with respect to thiscarcass rail 2, can be pushed back into its end position. In the fully pulled-out position of the guidingrail 1 illustrated inFIGS. 6 and 7 , thecenter rail 4 is blocked with respect to thecarcass rail 2 by means of thenotch lever 12. In this condition, one of the snap-inteeth 6 is situated in front of theforward face edge 4 a of thecenter rail 4. This means that, in this position, the runningrail 3 also cannot be displaced in the closing direction with respect to thecenter rail 4, so that the entire system is blocked. A drawer part connected with the runningrail 3 is thereby secured in the fully opened position against an unintended pushing-back. - To collapse the guiding
rail 1 from the extended position, it is necessary to rotate therod 5 by means of itshandle 10 to such an extent that the snap-intooth 6 is swiveled out of the contact area to theforward face edge 4 a of thecenter rail 4. Then, the runningrail 3 can be displaced in the closing direction with respect to thecenter rail 4. In this case, thecenter rail 4 is at first still blocked by thenotch lever 12 with respect to thecarcass rail 2. During the slide-in movement of the runningrail 3, theoperating lug 3 a connected to the rearward end of the runningrail 3 arrives in the contact area to the operatingnose 12 a of thenotch lever 12 and lifts the latter, as described above, to such an extent that the locking of thecenter rail 4 with respect to thecarcass rail 2 is eliminated and the guidingrail 1, as a whole, can be moved into its pushed-together condition. - The two snap-in
teeth 6 have a distance from one another which differs from all distances between all mounting openings not indicated in detail within thecenter rail 4 and thecarcass rail 2 in order to prevent that the snap-inteeth 6 swivel in an unintended manner into one of these openings. - In order to be able to engage in the
openings 7 of thecarcass rail 2, the snap-inteeth 6 have to be able to also pass through thecenter rail 4. For this purpose, correspondingopenings 4 b (seeFIGS. 5 and 7 ) are provided within thecenter rail 4. - The construction illustrated also provides for the potential situation where, as a result of an unfortunate displacement movement in which the snap-in
teeth 6 pass through thecenter rail 4 before they rest on thecarcass rail 2, the drawer part may be pushed into a closed position without hindrance. To allow for this possible situation, anotch 2 b with aninlet slope 2 c at the forward face-side end 2 a of the carcass rail is provided. The snap-inteeth 6 are automatically swiveled back into the area of thecarcass rail 2 against the effect of thespring 11 loading the snap-inteeth 6 when the snap-in teeth engage theinlet slope 2 c of thenotch 2 b. - The above-described construction simplifies removal of the blockages from the closed to the fully extended positions of the guiding
rail 1. In addition, the above-described construction also discourages unintended collapse of the guidingrail 1 by an involuntary force applied to the end of the drawer when the guidingrail 1 is in the extended position. - The described construction provides for elimination of a blockage (or a blocked condition) without the need to apply forces more than required to push in or pull out the drawer part. All that is required to remove the blockage is to swivel the snap-in
teeth 6 by the rotation of therod 5, by way of itshandle 10, out of its blocking position. - It is noted that the construction is such that unintentionally high loads upon the guiding
rail 1 in the pull-out or slide-in direction cannot eliminate a blockage. As a result, the elimination of a blocking position by a user can be carried out very easily, but not by means of unintended manipulations or loads upon the guidingrail 1. In this context, it should be mentioned that a prevention of an unintended displacement movement of a corresponding guiding rail also increases safety.
