Abstract

The present invention relates to a clamp (9) for mounting on a cylindrical article (8), comprising at least one first component part (10), enclosing the cylindrical article at least over part of its periphery, and at least one second component part (20) which encloses the cylindrical article likewise at least over part of its periphery and which can be connected to the first component part to form the clamp. According to the invention, provision is made for it to be possible to connect said first component part (10) to the second component part (20) by pushing it in in a direction parallel to the axis of the cylindrical article (8). The clamp (9) according to the invention can be mounted without any problems on a cylindrical article (8) which is not accessible for pushing on the (complete) clamp from the end, as is the case, for example, with a telescopic rod clamped in place between ceiling and floor. The invention provides for a push-in part (30) having a fastening element (31) or the like to be capable of being attached, by pushing it in, in a releasable manner from outside to the clamp already mounted on the cylindrical article.

Description

clamp

The present invention relates to a clamp for mounting on a cylindrical object comprising at least one first item enclosing the cylindrical object over at least a portion of its circumference and at least one second item enclosing the cylindrical object also over at least a portion of its circumference and connected to the first item is connectable to form the clamp, wherein the first item is connectable by insertion in the direction parallel to the axis of the cylindrical object with the second item.

Conventionally, a clamp of the aforementioned type, which usually consists of two interconnectable items, attached to the cylindrical object which it is to enclose, in any form and then fixed, for example by screws in the mounting position on the cylindrical object. There are clamps which are first pushed in the axial direction of the cylindrical object from the end thereof and advanced into the intended mounting position. In certain applications, such as when the cylindrical object is a telescoping pole fixedly clamped, for example, between a floor and a ceiling of a room, it is no longer possible after assembly to push the clamp from the end to the telescopic pole , The telescopic rod would therefore first have to be disassembled in order to be able to push the clamp of the conventional type from the end of the rod. Subsequently, after attachment of the clamp then the telescopic rod would have to be set up again and clamped. It is obvious that this is time consuming and expensive for the user.

In DE 35 18 813 C2 a designated for attachment to pipes flange is described in which the flange comprises a first clamp portion in the form of a half-shell, which partially overlaps the tube and which is then connected by axial displacement with a second complementary clamp portion, so that then by a complete tube enclosing clamp is formed. Of the one clamp section is in the radial direction from an arm with a sleeve, so that a screw anchoring the clamp (the flange) can be done on a wall. A variable attachment of further fastening or holding elements on one of the items of the clamp is not provided here.

The DT 24 29 121 A1 describes a two-piece pipe clamp for steam and water pipes. In this generic clamp is provided to attach the two-piece clamp by means of an anchor bolt on a wall to set the water pipe there. The one clamp half has a groove for the head of the anchor bolt, which receives this, so as to serve as anti-rotation. During assembly, however, the procedure is that initially the shaft of the anchor bolt is inserted from the inside radially through a hole in the clamp half and then the two clamp halves are connected together. So it is not intended and not possible, after connecting both clamp halves outside of the clamp to install another component.

The object of the present invention is therefore to provide a clamp of the type mentioned, in which even after the assembly of the clamp attached to the cylindrical object functional elements outside the outer circumference of the clamp such as holding or fastening elements or replaced can be and thus the clamp can be made more variable.

The solution to this problem provides a clamp according to the invention of the aforementioned type with the characterizing features of the main claim. According to the invention, it is provided that at least one insertion part is present, which can be inserted from the outside into at least one groove of one of the individual parts of the mounted clamp, approximately axially parallel relative to the cylindrical object to be enclosed by the clamp.

This results in the particular advantage that it is possible to exchange a fastener or retaining element associated with the clamp, for example, as a result of which the clamp can be made substantially more variable and result in a variety of possible uses for the clamp. The said fastening element or retaining element is thus not fixedly attached to the clamp, unlike in known solutions, but is located at the insertion part, which is preferably also released when mounted on the cylindrical article clamp from its connection with one of the items and thus removed from the clamp can be, by a simple sliding movement. So you can then replace, for example, the original insertion part by another, on which there may be a differently designed fastener or retaining element. The named Fastener or retaining element is usually assigned a specific function that determines the intended use of the clamp. By way of example, as fasteners knobs, knob or the like called or hooks, which are located on the insertion part and thus after its insertion on the clamp.

At the insertion part may for example also be a web which projects, for example, in approximately radial direction of this, on which then a rail can be pushed. It can also be provided, for example, at least one insertion part, a groove or recess into which a bracket, which serves as a holding element, can be inserted. For example, in turn, a holder for objects or a holding element can be fixedly attached to said bracket. In the latter case, therefore, it is possible to hook the bracket with the holder into the insertion part and thus fasten such a holder in a rather simple manner to the clamp. The aforementioned exemplary embodiments show that the solution according to the invention provides numerous possibilities for using the clamp without the clamp having to be removed from its mounting position on the cylindrical object when the use is changed.

In a clamp of the type according to the invention, the first item is connectable by insertion in the direction parallel to the axis of the cylindrical object with the second item. The clamp according to the invention can be easily mounted on a cylindrical object which is not accessible for pushing the (full) clamp from the end, as is the case, for example, in a clamped between the ceiling and floor telescopic rod. In the solution according to the invention, the second individual part of the clamp is simply attached to the cylindrical object in such a way that this second individual part partially encloses the cylindrical object, then applies the first individual part correspondingly to the circumference of the clamp, so that it likewise engages the latter at a part of its Surrounds circumference, and then pushes the first item in the axis-parallel direction along the cylindrical object until the engagement between the two parts is given and their relative end position is reached, in which both items are at the same height or together a complete cylindrical object form enclosing clamp.

If you, which is provided according to a preferred variant of the invention, each of the inner side portion of the two items, so their shots, each slightly conical forms, then you get when pushing together the two items a particularly strong connection. It is also possible, for example, to foam the individual parts in the region of their receptacles, in order to reinforce the effect mentioned above. The clamp according to the invention may consist of more than two individual parts, which are joined together to form a complete clamp. Accordingly, each of the individual parts does not necessarily have to enclose about half the circumference of the cylindrical object, but this may also be a smaller or larger peripheral region. A clamp according to the invention can also consist of more than two individual parts which complement each other in the axial direction to form a clamp or even only a partial clamp or respectively to a first individual part or a second individual part in the sense of the above definition. The individual parts according to the invention may comprise different sized peripheral areas of the cylindrical object and also have a different extent in the axial direction, at least in partial areas, that is, the individual parts may for example also have a stepped (in the axial direction) shape. In all cases, the general principle according to the invention is applied to assemble a complete peripheral clamp for a cylindrical object from two or more axially parallel with respect to the cylindrical object to be enclosed against each other and slidable one another.

According to a preferred embodiment of the task solution according to the invention each corresponding to each other elements are provided on the first item and the second item, which engage in the insertion for connecting the two items together. In this way it is possible, for example, to produce an at least partially form-fitting connection between the first and the second individual part. Likewise, one can thereby effect a mutual guidance of the two parts in the insertion movement to their connection. Such interlocking corresponding elements may analogously be present on more than two individual parts, when the clamp is composed of more than two such items.

As such mutually interlocking elements corresponding to each other, for example, at least one profile groove may be provided on the one individual part and at least one profile web on the other individual part.

Furthermore, at least one stop element can preferably be provided on at least one of the at least two individual parts of the clamp, which defines an end position when inserting the first item into the second item. As such stop elements come, for example, each stop surfaces on the items into consideration. Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings. Showing:

Reference will first be made to FIGS. 1 a to 1 c, which show the clamp according to the invention in a perspective view, once in the assembly (FIG. 1 a), in a partially exploded view (FIG. 1 b) and in a fully exploded view (FIG. 1 c) ). The clamp according to the invention comprises, in principle, two individual parts 10, 20 which can be connected to one another in a detachable manner, which in turn, when mounted, form a cylindrical object, for example a rod-shaped structure, such as a telescopic rod 8 (see FIG a) or the like completely encloses the circumference. As can be seen from FIG. 1 c, both individual parts 10, 20 of the clamp form, in principle, half-shells each enclosing the cylindrical object to which they are fastened approximately over half their circumference, and thus forming a cylindrical object Complete complete collar for a cylindrical object. The assembly to the complete clamp is done by inserting the first item 10, which is provided with corresponding profile webs, from above into the second item 20, which has corresponding profile grooves with said profile webs. The design of the two individual parts 10, 20 and their profile webs or profile grooves will be explained in more detail later with reference to Figures 4 to 7 and 8 to 11 in detail. From Figure 1 b, however, you can see well how the first item 10 is inserted from above form-fitting manner in the second item 20 until the mounting position is reached, in which there is a complete clamp, which is shown in Figure 1 a.

Figures 2 and 3 respectively show the complete clamp 9, once in plan view and once in side view. The two individual parts 10, 20 form two half shells of the clamp 9, which enclose a cylindrical cavity on the inside. On the outer circumference, however, the clamp 9 is not formed completely cylindrical, since the item 10 has a slightly different from the circular shape outer contour, as can be seen well from the plan view of Figure 2. On one side, the clamp 9 is outside something flattened, where there is inserted an insertion part 30 in grooves of the first item 10. The reason for this is that there is a fastening element 31 on the insertion part 30, which is designed, for example, like a button or a knob. This creates according to the invention the possibility of replacing the insertion part 30 with an alternative component (not shown) on which a differently configured fastening element is located. By this measure, it is possible to make a clamp invention variable. After replacement of the insertion part 30 is obtained, for example, a clamp that fulfills a different function due to their differently shaped fastener than the clamp shown in Figures 1 to 3, wherein the two individual parts 10 and 20 of the clamp can remain unchanged, and wherein advantageously Way also the clamp can remain in its mounting position (on a rod), since only the insertion part 30 is replaced.

Hereinafter, the details of the first item 10 of the clamp 9 will be explained in more detail with reference to Figures 4 to 7. From the perspective view of Figure 7 and the plan view of Figure 6 can be seen clearly that the first item 10 of the clamp inside a semi-cylindrical receptacle 14 which is adapted to enclose a cylindrical object in half at its periphery. On its outside, the item has seen in plan view in approximately a trapezoidal shape. On the upper side (in the mounted state), a kind of collar is formed on the right and left with two legs 17, 18, each of which projects slightly beyond profile grooves 15, 16, which can also be clearly seen in FIG. By this supernatant results in each case a return on the underside of the collar, through each of which a horizontal stop surface 19 is formed, whose function will be explained later in more detail. The two profile grooves 15, 16 extend axially parallel to the axis of the semi-cylindrical receptacle 14 and extend from the lower end of the item 10 each up to the stop surface 19. The profile of the two profile grooves 15, 16 can be seen in the plan view of FIG , The two profile grooves 15, 16 virtually form the guide upon insertion of the first item 10 in the second item 20, these profile grooves form a positive connection with correspondingly shaped profile webs of the second item 20.

Another feature of the first item 10 is formed on the rectilinear front side of the item transversely extending guide web 11 which forms the connecting element and guide element for the third item of the clamp 9, namely the insertion part 30, which is shown in Figures 12 to 15. It can be seen in FIG. 6 that the guide web 11 extends at a distance from the body 14a of the individual part 10, so that a groove 12 results behind the guide web 11. In addition, the guide bar on the outside Side of the clamp arranged slightly receding, so that there is a recess 13, whose function will be explained later in the description of the insertion part 30 in more detail.

The second individual part 20 of the clamp will now be described in greater detail below with reference to FIGS. 8 to 11. This second item 20 has a semi-cylindrical receptacle 24 on its inner side, which complements with the receptacle 14 of the first item to the cylindrical receptacle enclosing the rod-shaped object. At the open circumferential end of the receptacle 24 in each case a profile web 21, 22, which can be seen particularly well in Figure 10. On the outside of the outline 25 of this second item 20 of the clamp in plan view runs circular, unlike the first item described above 10, whose rather trapezoidal configuration is to lead back to the local arrangement of the insertion part.

The upper edge of the semi-cylindrical item 20 does not run over its entire circumference, but ends as well from Figure 11 and 8 recognizes with some distance from the edge of the component and that where the profile webs 21, 22 begin. As a result, as shown in FIG. 8, a step or recess 26 is formed above each of the profile webs 21, 22 and the profile web 21, 22 ends on the upper side in a stop surface 23 horizontal in the mounting position. The profile of the profile webs 21, 22 is in the plan view according to FIG seen in approximately hook-shaped, with indentations 27 are located behind each hook-like structures and the back of the hook-like structures undercuts 28 are formed.

The details of the insertion part 30 according to a possible embodiment of the present invention will be described in more detail below with reference to FIGS. 12 to 15. In the side view of Figure 12 and also in the perspective view of Figure 15 can be seen that it is in the insertion part 30 is in principle a U-shaped bent component, with two parallel legs 32, 33 and one in the in the Mounting position on the top side, the two legs 32, 33 interconnecting and extending approximately perpendicular to this web 36. Between the two legs 32, 33 which extend at a distance to each other, an approximately rectangular receptacle 34 of the insertion part is formed. This recording is open on one side, namely where the web 36 opposite ends of the two legs 32, 33 are located. On this side, the respective ends of the two legs are thus free. The shape of the insertion part 30 according to this embodiment can also be referred to as a clasp-like manner.

On the outside of the leg 33 is a kind of knob 31 or knob arranged, which has a round outline and the reduced by a radius also round approach 35 is connected to the outer surface of the leg 33. This button 31 serves as a fastener for attaching various items to the clamp.

Reference is again made to the figures 1 a to 1 c reference and explained with reference to this, the assembly of the clamp 9 according to the invention from the two individual parts 10, 20 and the insertion part 30. Figure 1 c shows the exploded view of the three components before assembly. The first item 10 is first inserted with its two profile grooves 15, 16 from above into the second item 20, that the profile grooves 15, 16 of the former engage positively in the two profile webs 21, 22 of the latter. It is a guided insertion movement, Figure 1 b illustrates the beginning of this insertion. The first item 10 is thereby inserted until the end position shown in Figure 1 a is reached, in which the stop surfaces 19 on the underside of the two legs 17, 18 of the collar of the first item 10 (see Figures 5 and 7) on the horizontal Stop surfaces 23 at the top of the profile webs 21, 22 of the second item 20 rest (see also Figures 8 and 11). This end position of the two assembled to the clamp 9 items 10 and 20 is shown in Figure 1 a.

Furthermore, as is apparent from FIGS. 1 c and 1 b, the insertion part 30 is inserted from above into the first individual part 10 in such a way that one leg 32 of the insertion part 30 (see FIG. 12) protrudes from the groove 12 of the first individual part 10 is received (see also Figure 6), while the second outer leg 33 of the insertion part 30 is received by the recess 13 of the first item 10. At the same time, the guide bar 11 of the first item 10 is received in the receptacle 34 of the insertion part 30. The incipient insertion of the insertion part 30 in the first item 10 shows the figure 1 b, the final insertion position of the insertion part 30 is shown in Figure 1 a. After this fast and. simple assembly of the three components 10, 20 and 30 thus a clamp 9 is obtained with integrated fastener 31 - in the embodiment a knob or Knauf-, a great inventive advantage is that the insertion part even when mounted on the rod 8 clamp simple removable and thus interchangeable with another insertion part with a differently shaped fastener, so that the clamp then obtained can serve a different function.

According to an alternative embodiment of the invention, which is not shown in the drawings described above, the insertion part may also have, for example, a groove or recess into which a bracket which serves as a holding element, can be inserted. This bracket can then either serve itself as a holder for objects or on this turn, a holding element, for example, firmly attached. According to a further variant, the insertion part can also have, for example, a receiving element, preferably a web projecting outward in the radial direction, on which (n) a rail can be pushed. On this rail you can then attach, for example, more objects or you put a kind of pipe or rod on this rail, creating a horizontal support member which complements a formed by a vertically arranged telescopic rod bracket for example. These examples show that the clamp can be made variable via the insert part, which can be exchanged if necessary, and that it can be assigned a variety of functions, with the clamp in each case being mounted on the cylindrical object.
