Definitions
- the invention relates to a revolving lid with a flat bar which has a cover foot and a web lying above the cover leg, and with a flexible set in the form of a clothing strip and with at least one fastening element in the form of a clip, wherein the clip is attached to the clothing strip with a first section , is guided along with a second portion on a longitudinal side of the flat bar along and partially encloses the cover foot with a wrap angle with a third portion.
- the wrap angle is defined as the angle between the perpendicular to the side surface of the lid leg perpendicular to
- the revolving lids are used for cards.
- the moving lid used today consist essentially of a flat bar with a
- the flat bar is composed of a cover foot and an overlying bridge.
- the set is fastened to the cover leg using clips.
- the clothing itself is used in the form of clothing strips, on the underside of which a plurality of clothing needles in the form of wire hooks is attached. At the two
- the US 581, 749 discloses a revolving lid and a corresponding tool for fixing the clothing strip on the cover leg.
- the clips are first connected to the clothing strip.
- the thus prepared GamiturstMail is joined together with the flat bar and then the free portions of the clips are bent around the cover foot around, so that the GamiturstMail comes to rest on the cover foot without play.
- the cover foot is thereby clamp-like covered by the clips.
- DE 128 552 also discloses the attachment of a flexible clothing in the form of a clothing strip on the cover leg of a flat bar.
- the clip used on the one hand engages in the foundation of the clothing strip and on the other hand, the clip surrounds or surrounds the cover foot. As a result, a firm seating of the lining material of the foundation of the clothing strip on the cover foot is made possible.
- Another disadvantage is the preparation of both sides bent clips.
- Figure 1 shows a device as it is used for mounting clothing strips on flat bars.
- the flat bar 1 is mounted on a previously set in a fixture 8 clothing strip 10, so that the lid foot 3 comes to rest on the clothing strip.
- the clips 5 are already mounted on the longitudinal sides.
- the flat bar 1 is thus inserted with the lid foot 3 between the clips 5.
- Vorbiegerollen 6 the clips 5 are preformed.
- the clips 5 are formed on the lid foot 3 with the forming rollers 7.
- Vorbiegerollen 6 and forming rollers 7 are moved to the formation of the clips 5 in the longitudinal direction of the flat bar 1 while rotating the rollers and pressed against the lid foot 3.
- the device shown has the disadvantage that only a certain shape of the lid foot 3 matches the given shape rollers 7. Also are complicated movement and
- WO 2006/039829 discloses another example of a device for attaching a clothing strip to a flat rod.
- a prepared clothing strip in which both sides of the clips are already attached to a first section, is inserted into the device.
- the flat bar is introduced with the lid foot against the clothing strip in the device, so that the clips with a second section along the long sides of the cover foot lead.
- the bending cheeks of the device are now pivoted inwardly against the flat bar, whereby the third portion of the clips is formed on the cover foot.
- To generate the necessary holding force is a deformation of the clips in addition with pressure bars generated along the long sides of the lid foot.
- a disadvantage of the device is that several movements of pressing tools and bending cheeks are necessary to achieve attachment of the clothing on the flat bar. There is also the danger that, if the clip is deformed too much, a change in the shape of the entire flat bar may result because different clips of the cover foot are spanned by the clips.
- a solution of the problem is achieved by the design of a Wanderdeckeis of the type mentioned, and by the method and the necessary tool with the characterizing features of the independent claims 1, 6 and 10.
- the object is achieved in that the clip with a third section the cover leg wraps around at an angle between 90 ° and 30 ° (degrees).
- a moving lid according to the invention has a flat bar.
- the flat bar is made up of the top leg and a bridge over the top leg.
- Flat bars are now usually made in one piece from steel or cast iron as well as in the form of hollow sections of light metal orchtmetalllegtechnikerr. Also
- a flexible clothing comprises a foundation made up of several fabric layers which is pierced by needles. The clothing is produced in the form of strips, the width and length of these clothing strips corresponding to the dimensions of the cover foot. Along the long sides of the cover foot, the clothing strip and the cover foot are held together with the aid of fastening elements, so-called clips.
- the clips have a first portion which is connected to the clothing strip.
- the frictional engagement is achieved by looping the cover leg through the third section of the clip. It has been found that a wrap of less than 90 ° leads to a frictional engagement between the lid foot and the clip, which meets the requirements that are made in operation to the connection of the cover foot and clothing strips. In terms of preparation and solubility of the compound has a
- a wrap angle of more than 30 °, preferably more than 50 ° is advantageous.
- the clip is made of light metal or a light metal alloy.
- the necessary forces for molding of the clip are reduced to the flat bar.
- the use of clips made of aluminum or an aluminum alloy has proven itself.
- the flat bars may be made of light metal or a light metal alloy.
- the flat bars may be formed as hollow profiles. Also, the use of aluminum or an aluminum alloy is advantageous.
- the procedure for forming the clips on the cover foot is characterized by the use of simple press dies.
- the ram act simultaneously on both sides of the flat bar on the clips to be formed.
- the press dies are thereby moved toward each other transversely to the longitudinal direction of the flat bar.
- the movement of the ram takes place linearly in a plane which is parallel to the plane of the clothing strip.
- the press punches can be provided with a drive.
- the drive can be electric, pneumatic or hydraulic. Also, a purely mechanical drive is conceivable, which can be actuated by hand.
- the flat bar has an additional rib above the lid foot, which runs along the length of the flat bar parallel to the lid leg.
- the rib forms a guide for the press dies together with the lid foot. The rams are guided by this rib during their movement so that they can not escape the clip.
- the press punches are preferably made of an elastic material, preferably of a thermoplastic plastic, in particular polyethylene or polyamide. This deforms the part of the ram that slides along the cover leg and the third section of the clip. As a result of this deformation, the pressing punch adapts to the contour of the clip and of the cover foot, which leads to the clip being molded onto the cover foot. By this exact molding of the clip to the contour of the cover foot, unevenness in the cover foot can be compensated. Also, a balance of manufacturing or form tolerances on the flat bar is possible. Already used and thus slightly damaged flat bars can be equipped by the proposed method again with a clothing strip. When the pressing process is completed, the punches are withdrawn and return to their original shape.
- a thermoplastic plastic in particular polyethylene or polyamide
- the tool used to carry out the method allows the inclusion of a flat bar.
- the clothing strip with the already attached clips and the flat bar are inserted into the tool. Subsequently, the
- Gamiturst and the flat bar held in position to each other.
- means are provided which on the one hand enable positioning of clothing strips and flat rod, for example guides, and on the other hand fix this position, for example, clamps, clamps.
- the flat bar is held with a hold-down during the subsequent pressing process.
- the simultaneously approaching press punches from both sides can be made in one piece and extend over the entire length of the clothing strip to be fastened. It is also a division of the ram in individual segments conceivable, the drive of the ram can also be divided into individual segments.
