Description

Rolling element cage manufacturing method for retaining rolling elements, pull-out guide and construction kit
The invention relates to a method for producing a rolling element cage with rolling elements, a pull-out guide and a kit for producing a rolling element cage with rolling elements.
EP 2,356,347 B1 discloses a rolling element cage for a pull-out guide, in which the side walls are connected to one another in a bendable manner along at least one longitudinal edge, and a latching device is provided, by means of which the side walls can be latched in a terminal position. This makes it possible to manufacture the rolling-element cage efficiently, since after the rolling-element cage has been manufactured, the rolling elements are inserted into the receptacles on the rolling-element cage and the side walls are bent, in order thereafter to mount the unit containing the rolling-element cage and the rolling elements on the pull-out guide. This process has been verified but requires production in several steps and additional feeding of the rolling bodies during production of the rolling body cage.
Instead of spherical rolling bodies, cylindrical rolling bodies can also be used for rolling body cages, as is disclosed, for example, in DE 10 2017 128 752.
It is therefore an object of the present invention to provide an improved method for producing a rolling element cage, a pull-out guide and a kit enabling an efficient production of a rolling element cage with rolling elements.
This object is solved with a method according to claim 1, a pull-out guide according to claim 10 and a kit having the features of claim 12.
In the method according to the invention, the strip-shaped body and the at least one holder with the at least one rolling element are injection molded, i.e. produced in one piece by injection molding, and then the at least one holder with the at least one rolling element is pivoted relative to the strip-shaped body such that the at least one rolling element is at least partially inserted into a receiving recess on the body. The at least one rolling element is then separated from the holder by separating the at least one connecting web, so that the at least one rolling element is subsequently rotatably held in the receiving recess on the body. This makes the production of the rolling-element cage with the rolling elements very efficient, since it is initially produced in one piece and the rolling elements are also formed in one piece. This prevents accidental loss of rolling bodies during assembly. The rolling bodies and the rolling body cage may be made of one or more components, such as plastic or metal, by injection molding.
Preferably, the at least one connecting web on the holder is designed as a predetermined breaking point, which is broken when a predetermined force is exceeded. This ensures that the rolling bodies are torn off at a predetermined point, so that each rolling body can be connected to the holder by means of one or more connecting webs.
For ease of installation, the at least one retainer may latch onto the body upon rotation. This ensures accurate positioning of the holder on the body.
According to one embodiment, bearing seats may be formed on opposite sides of each receiving pocket, into which bearing pins on the rolling bodies are inserted when the at least one rolling body is separated from the holder. The rolling bodies can then be rotatably held in the receiving pockets by means of two bearing pins. The bearing housing forms part of or forms the receiving recess.
Preferably, the retaining element is connected to the bearing pin of the at least one rolling element by a connecting web and is formed in one piece. This enables the at least one rolling element to be separated from the holder by applying a force perpendicular to the axial direction of the rolling element.
According to a preferred embodiment, the rolling element cage has a body, and during injection molding two or more holders, each having at least one rolling element, are injection molded integrally with the body. In particular, two holders may be provided, which are arranged on opposite sides of the body in the assembled position. Optionally, more than two retainers may be integrally formed with the body, each retainer having at least one rolling element molded thereon. By means of the frame-shaped design of the holder, a plurality of rolling bodies can be produced simultaneously in the frame during the injection molding process.
In this method, the at least one rolling element is preferably released only after the body has been slid onto the guide rail of the pull-out guide. The rolling element cage can thus be mounted as a unit with the rolling elements, and the rolling elements can only be separated from the holder after the rolling element cage has been arranged on the rail, for example by pressing the rolling elements in the direction of the running surface of the rail. This avoids accidental losses of the rolling bodies during assembly.
In the pull-out guide according to the invention, a rolling body cage produced by the method according to the invention is used, wherein the pull-out guide has at least two guide rails which can be moved relative to one another and which can be moved relative to one another by means of the rolling bodies. Preferably, the pull-out guide may be installed without tools.
In the inventive kit for producing a rolling element cage with rolling elements, the strip-shaped body is formed integrally with at least one holder and at least one rolling element. The one-piece kit can then be processed as a rolling body cage by a corresponding assembly step, wherein the rolling bodies are rotatably held on the receiving pockets of the body. The at least one rolling element is connected to the holder by at least one predetermined breaking point, so that a simple incision of the predetermined breaking point is sufficient for assembly. The kit is preferably assembled without tools, i.e. by hand. In the kit, the at least one rolling element may be made of the same or different composition as the holder and/or the body, e.g. plastic. Optionally, different compositions are used, e.g. harder plastics such as
POM is used for rolling bodies, not for bodies or holders.
The invention is explained in more detail below by way of exemplary embodiments with reference to the attached drawing, in which:
fig.1A to 1F show several views of a rolling element cage according to the invention with rolling elements;
figures 2A to 2D show several views of the assembly of the rolling element cage, and
fig.3A to 3E show several views of the assembly of the rolling element cage according to the invention on a drawer slide.
The rolling element cage 1 comprises a strip-like body 2 on which two holders 3 and 4 are integrally formed. The holder 3 is connected to the body 2 by at least one membrane hinge 5 and can be pivoted relative to the body 2 for assembly. In a similar manner, the holder 4 is formed integrally with the strip-like body 2 by means of at least one film hinge 6.
The holder 3 is shaped like a frame in which several rolling bodies 7 are arranged, which are integrated with the holder 3. In the exemplary embodiment shown, four rolling elements 7 are formed on the holder 3, however the number of rolling elements 7 on the holder 3 may be varied as desired. The holder 4 is also frame-shaped, enclosing four integrally formed rolling bodies 8.
The rolling bodies 7 and 8 are cylindrical but may also have different geometries, for example cylindrical or spherical.
The body 2 is strip-shaped and comprises a number of receiving pockets 10 for the rolling bodies 7 and 8. The receiving pockets 10 are provided on opposite sides of the body 2 and have different dimensions in the present exemplary embodiment, since the rolling bodies 7 and 8 also have different dimensions. However, it is also possible to use rolling bodies 7 and 8 of the same size, which are then inserted into receiving pockets 10 of the same size.
Fig.1E shows in detail the receiving pockets 10, each having a bearing seat 11 and 12 on opposite end faces. The bearing housing 11 is in the shape of a recess, while the bearing housing 12 is continuous on one wall of the body. It can also be seen that several sliding projections 13 are provided on the body 2, which ensure that the rolling body cage is positioned within the pull-out guide and is for example centrally positioned between two guide rails of the pull-out guide or can slide on a third or fourth surface of the pull-out guide.
Fig.1F shows the connection of the rolling elements 7 to the cage 3. The rolling bodies 7 comprise cylindrical bearing pins 14 which can be inserted into one of the bearing blocks 11 or 12. A connecting web 15 is integrally formed on the bearing pin 14, which web serves as a predetermined breaking point, ensuring that the rolling elements 7 can be separated from the cage 3. The rolling bodies 8 are connected to the holder 4 in the same way. The diameter of the bearing pin 14 can be adjusted according to the required load and the bearing blocks 11 and 12. The strength of the connecting web 15 can also be adjusted to avoid an accidental loosening of one of the rolling bodies 7, 8.
Fig.2A to 2D show the assembly of the one-piece rolling element cage 1. The rolling element cage 1 made in one piece as shown in fig.1A to 1F is deformed in a first step: the holder 3 is pivoted relative to the body 2 by at least one membrane hinge 5, in particular two membrane hinges 5 formed at opposite ends of the holder 3. In a similar manner, the holder 4 pivots about at least one film hinge 6, as shown in fig. 2A.
The holder 3 is pivoted onto the body 2 and is latched thereto by a latch lever 9 (fig. 1E) which is integrally formed on the body 2 or the holder 3. The holder 4 is latched to the main body 2 in a similar manner but on the opposite side to the holder 3. Optionally, another mechanism may also be used to secure the holder 3 or 4 to the body, such as a clamp, to ensure that the holders 3 and 4 are secured to the body 2.
In fig.2C, the holders 3 and 4 are folded onto the body 2, a corner slot 20 being visible in which a part of the rail 16 of the pull-out guide 24 can be inserted. The rolling bodies 7 and 8 are still fixed to the holding element 3 or 4 and can now be separated from the holding element 3 or 4 by a force, as schematically indicated by the arrows pointing upwards or downwards. In fig.2D, the rolling bodies 7 and 8 are pressed in the direction of the body 2 and inserted into the receiving pockets 10, so that the bearing pins 14 on the rolling bodies 7 and 8 are inserted into the bearing seats 11 and 12. The rolling bodies 7 and 8 protrude outwardly from the main body 2 on opposite sides. On the other two sides, the sliding protrusions 13 prevent the rail from striking the main body 2.
The assembly of the rolling element cage 1 on the pull-out guide 24 is shown in fig.3A to 3E. In a first step, a pre-assembled rolling element cage 1 is placed, wherein the holders 3 and 4 have been pivoted and clamped as shown in fig.2A and 2B, with the strip-shaped body 2 resting on the stationary rail 16 at the corner segments 17, the corner segments 17 being inserted into the vertical portions of the corner slots 20 of the body 2.
According to fig.3B, the rolling element cage 1 is now rotated about its longitudinal axis, so that the rolling elements 7 and 8 are arranged on the upper and lower sides of the runway on the corner section 17, but still a distance.
The rolling is embodied in a direction perpendicular to the axial direction towards the body 2, as shown in detail in fig.2C and 2D, so that the rolling bodies 7 and 8 can roll along the racetrack on the corner segment 17. The release of the rolling bodies 7 and 8 from the holders 3 and 4 can be carried out manually before the rail 18 is pushed up or in the assembled state by loading the rail 18.
Once the rolling element cage 1 is installed, the second movable rail 18 can now be slid onto the rolling element cage 1 and the stationary rail 16. The rail 18 comprises an opening 19 in which fastening means 21 in the form of a web can be inserted to secure the movable rail 18 against removal from the stationary rail 16. The fastening means 21 can act as a stop against the end face of the rolling element cage 1 in the end position.
Further, a protrusion 22 is formed or mounted on the fastening means 21, which acts as an actuator and can be engaged with the self-closing mechanism 23, which self-closing mechanism 23 has a movable driver which can be moved between two end positions by the actuator.
In addition to the self-closing mechanism 23, the ejection device can also be actuated by an actuator, wherein the movable furniture part can be ejected from the closed position in the opening direction.
The pull out guide may be used in furniture, household appliances, automotive consoles, or other applications.
