Definitions

• the invention relates to a protective element for pushing or pushing onto or into a rod-shaped part, in particular, according to the preamble of patent claim 1.
• Such protective elements are known from DE 27 23 923 A1 or FR 2 548 144 A1.
• the document mentioned first relates to a slide-on protective sleeve in the form of a plug-on cap that is closed on one side.
• the subject of the second document is an insertable stopper with resilient lamellae attached in the longitudinal and radial directions. This plug is provided with an end cap on one side.
• the invention is concerned with the problem of making such protective elements more rationally producible.
• it should first and foremost be important to protect the outer circumference against mechanical damage by embedding in such a protective element, or to protect the interior Inner circumference of a hollow rod-shaped part by a plug-shaped protective element to be inserted. Secondary importance should be a sealing on the end face of the rod-shaped part to be protected against mechanical damage by the protective element in question.
• a same protective element should be usable for parts to be protected with a relatively large area of different sizes.
• Such a protective element can be separated from a practically endless tube with molded resilient longitudinal slats in any length.
• the tubes can be made of plastic and can be produced, for example, by extrusion.
• a separate cap can be fitted. It can be snapped on, snapped into place, or clamped or unclamped.
• protective sleeves expediently have a longitudinal slot for opening in the circumferential direction. In the unfolded state, such protective sleeves can extend transversely to the longitudinal direction of a rod-shaped part to be pushed onto this.
• edges forming the longitudinal slot of such a protective element can be designed to be mutually hookable in order to ensure a secure closure of the protective element in the opened state.
• a film hinge running in the same direction opposite the slot can be introduced or molded into the jacket of the protective element.
• a protective sleeve which can be opened in the longitudinal direction can also consist of two separate parts which can be connected to one another. The connection can be made by interlocking the two parts, the edges adjacent to both parts having to be designed with corresponding hook shapes.
• the cross-sectional shape of a protective sleeve according to the invention can be square, in particular square and square.
• An angular, in particular square, cross-sectional shape is particularly expedient in relation to the storage and handling of protective sleeves.
• Show it 1 is a perspective view of the end region of a cylindrical tubular protective sleeve with straight spring lamellae
• FIG. 2 shows a perspective view of a cylindrical tubular protective sleeve with spring lamellae of arcuate cross section
• FIG. 3 is a perspective view of a protective sleeve with a square box cross section
• Fig. 4 is a perspective view of a hinged protective sleeve with a cylindrical tubular cross section
• FIG. 5 is a perspective view of a hinged protective sleeve with a box-shaped sleeve cross section
• FIG. 6 shows a view of the protective sleeve according to FIG. 5 in the opened state
• FIG. 7 shows a perspective view of a protective sleeve which is divided in two in the longitudinal direction
• FIG. 8 is a view of the end of a stopper with externally attached lamellae and a clip-on cover
• FIG. 9 shows a side view of the stopper according to FIG. 8 m exploded view.
• protective elements are shown in the form of protective sleeves. These protective sleeves are each placed on a rod-shaped part 1 to be protected on its outer circumference.
• the protective sleeves can be folded open or divided into two, so that they can be pushed open in the opened or separated state transversely to the longitudinal direction of a rod-shaped part 1 to be protected.
• Resiliently flexible longitudinal slats 2 are formed in each case on the inside of the protective sleeves.
• the longitudinal lamellae 2 running in the longitudinal direction of the protective sleeves are resilient and very flexible, so that they can be placed on rod-shaped parts with relatively large outside diameters.
• rod-shaped parts 1 with a larger diameter are indicated by dot-dash lines in the protective sleeves. With a rod-shaped part 1 with Such a larger diameter, the fins 2 easily put on the outside by bending accordingly more.
• the rod-shaped parts 1 can also have any angular cross sections in addition to rounds.
• the protective sleeves have film hinges 3 running in the longitudinal direction on one side and hook fasteners 4 on each opposite side.
• the four lamellae 2 provided in all versions of the protective case are attached in such a way that each lamella 2 has one lamella 2 approximately parallel to the opening plane of this protective sleeve half and the other Lamel ⁇ le 2 runs perpendicular to this opening plane.
• the protective sleeve consists of two identical longitudinal halves which are connected to one another in a twisted manner via a hook closure 4. This hook closure also receives its closing force exclusively from lamellae 2 clamped to a part 1 to be protected.
• a hook closure 4 which is independent of the tensioning force of the lamellae 2 can be achieved in that the hook closure 4 is designed as a latching or snap closure.
• slats 2 are a stopper with resilient slats 2 attached to its outer circumference. These slats 2 can be resiliently bent circumferentially. As a result, this plug can be inserted into cavities with different internal diameters in a radially exciting manner.
• the stopper shown is provided with a clip-on cover 5.
• the protective sleeves can also be covered with a cover in a similar manner on the ends.
• the resilient lamellae 2 are each formed from the wall material of the protective sleeve or the plug core, these can also be subsequently connected to the protective sleeve or the plug base part as separately manufactured parts. This can for example, by snap or snap locks. Subsequent gluing or welding is also possible.
• the particular advantage of the protective elements according to the invention is that they can be separated from tubes which are practically endlessly prefabricable in any lengths. This ensures extremely efficient production and low warehousing.
• the low level of storage results from the fact that protective elements of different lengths can be cut to length from the same storage material as required.
