Description

Technical Field

[0001] The invention relates to a device for manually introducing holes and / or rivets into workpieces. In particular, planar workpieces such as textiles of any kind, leather, plastic films, paper and cardboard and similar materials can be used as workpieces, but also thicker workpieces such as foam materials or very fluffy materials. The choice of material for the workpiece is not restricted here. Background Art

[0002] It is in the field of handicrafts, clothing and accessories manufacturing and upcycling that there is a desire to introduce holes and / or different types of rivets into workpieces, whether for fixing purposes, as in the case of classic belt holes and buttons, or for decorative purposes, as in the case of decorative rivets and other objects. The shape of the holes and rivets is not restricted here. A "rivet" is understood here to be any object that is fixed to an object by riveting or crimping, whether it has another function or a decorative effect, and whether it is arranged on one or more layers of the workpiece.

[0003] The following punching pliers and riveting pliers are well known, with the help of which corresponding holes and rivets can be introduced into clothing, textiles, leather and other materials. These usually contain a plurality of male molds and a female mold for different sizes. The workpiece is introduced between the male mold and the female mold, and the workpiece is processed by manually pressing the two pliers legs together. For example, documents DE29516991U1 or DE4422103C2 describe such manual punching pliers or riveting pliers. The operator needs to use relatively much force to operate, and the operator must also apply the force by closing his hand for this purpose. However, not every operator can achieve this without problems, especially in the case of thicker or heavier materials or in the case of larger holes or rivets.

[0004] DE 202013100917 U1 describes a folding machine which is designed as a tabletop device to be manually operated. This folding machine is used for folding or perforating special papers and has the possibility of adjusting the distance to the paper to be perforated in order to place the holes at the desired location. The disadvantage here is that, depending on the paper to be processed, the operator always has to apply high forces to carry out the processing. In addition, there is no provision for riveting the workpieces.

[0005] DE102011015473A1 also describes a manual paper puncher designed as a tabletop device. Since the force to be applied when punching paper varies greatly, and thicker stacks in particular can only be punched poorly with conventional punchers, the operating part is designed as a crank lever, which provides a better force change, so that even thicker paper stacks can be easily punched manually by an operator. Even in this device, riveting or similar processes are not provided. The distance between the tools or between the punch and the hole cannot be adjusted, but when the operating part is manipulated, the punch is always guided until it enters the hole. Summary of the invention

[0006] The object of the present invention is therefore to improve a device for inserting holes and / or rivets into workpieces in such a way that the operator can operate it with as little force as possible. It is also intended to adapt the distance between the tools in order to process rivets of different sizes or heights. This object is achieved by the characterizing features of claim 1, which have the following particular significance.

[0007] The device has a body with a working area with a tool plate and a pivotable operating part. In addition, a movable slide with a tool receiving part is provided. Tools can be arranged on the tool plate and a counter tool can be introduced into the tool receiving part. The workpiece to be processed, for example a workpiece consisting of textiles or leather or an object consisting of another material, can be introduced into the working area. By operating the operating part, the slide can be moved toward the tool plate until the tool and the counter tool are in operative connection with each other and the workpiece is processed. Depending on the choice of tool and counter tool, holes or rivets or similar objects that can be introduced into the workpiece by riveting, crimping or flanging can be processed in this way.

[0008] Since not only the workpiece but also the tool and the counter-tool can have different sizes, a stop is provided on the body, which can interact with a counter-stop on the operating part in order to limit the movement of the operating part and thus the movement of the slide. The invention now proposes that the stop is designed to be adjustable in order to limit the working position of the slide differently for different application cases. As a result, the working position of the slide can be adjusted exactly for each specific application case.

[0009] In a particularly preferred embodiment, the stop can be adjusted manually in an infinitely variable manner. Then, the precise adjustment of the working position of the slide can be carried out particularly easily for the operator and without additional tools.

[0010] If the stop is arranged at the stop screw, a stepless adjustability of the stop can be achieved particularly easily. The stop screw can then itself be located in a bushing, such as a threaded bushing. As a result, independent of the choice of the material of the body, an easy and stepless adjustability of the stop can be achieved. The threaded bushing can also be introduced into the body or arranged at the body in a conventional manner. The stop screw can have knurling or the like on its outer side or can be embodied as a wing screw in order to achieve simple manual adjustability without the use of tools.

[0011] It is also preferred that a first pivot axis is provided at the articulated element. The operating part can be pivoted around the articulated element about the first pivot axis. In addition, however, the articulated element is constructed in the manner of a crank lever and has a second pivot axis, by means of which the articulated element can be pivoted around the body. This allows for a better force transmission of the pivoting movement of the operating part. In order to achieve an orderly linear movement of the slider, a third pivot axis can be provided, which pivotally connects the slider to the operating part. This allows for the pivoting movement of the operating part to be converted into a linear movement of the slider. The mutual cooperation of the three pivot axes allows for a particularly good force transmission of the force applied to the operating part and the resulting pivoting movement of the operating part to the linear movement of the slider, thereby enabling safe processing of the workpiece, even when the rivet to be processed is large.

[0012] Different tools and / or counter tools can be arranged in the tool receiving portion at the slide and / or at the tool plate. This allows a wide variety of rivets to be processed or holes of different sizes and / or shapes to be introduced into the workpiece. Only one device is required for a wide variety of applications.

[0013] In order to perform safe processing of the workpiece, the device can have a fixing mechanism, by means of which the device can be fixed to a plate, such as a table. Thus, the device can be reliably fixed in the working position, and one or more holes and / or rivets can be arranged at the desired position at the workpiece in a targeted manner. Then, even when a large force is applied, the device will not move accidentally. For example, the fixing mechanism can include a roughly U-shaped clamp, which surrounds the edge of the plate in the installed state. Here, one leg of the clamp can be fixed to the device, especially to the receiving portion at the main body, and the other leg of the clamp can be fixed to the side of the plate away from the device. Thus, the U-shaped clamp surrounds the plate, and the device can be fixed to the plate with the clamp connected in the middle. The other leg can preferably be fixed to the plate by means of a detachable connection, for example, by a clamping connection. For this purpose, the other leg of the clamp is passed through or surrounded by a fixing device, which acts against the plate indirectly or directly against the plate, and the plate is supported at the plate. Furthermore, a protective cover can be provided which can be arranged between the plate and the counter-plate and protects the plate from damage, such as dents which can occur due to clamping of the counter-plate. By means of such a fixing mechanism, the device can be fixed to conventional plates, such as tabletops, shelf bottoms or the like, without thereby damaging the plate. After use, the device can then also be removed from the plate again. As a result, the device can be securely fixed almost anywhere and is therefore also well suited for use in the hobby sector, in particular.

[0014] In order to introduce holes or rivets into the workpiece in a targeted manner, one or more measuring scales can be provided at the device. This allows the exact distance to the edge of the workpiece to be measured and the hole or rivet to be introduced there. On one or more measuring scales, for example, the position of the tool relative to the edge of the workpiece can be read. One or more of the measuring scales can also be arranged at the device in a movable manner and / or in a releasably fixable manner. It is also possible to provide one or more projections at the measuring scales, against which the edge of the workpiece can rest, so that the hole or rivet can be introduced into the workpiece more easily at the exact measured location. The number and arrangement of the measuring scales can vary here.

[0015] For a better haptic feel, the operating part can be composed of two components, namely a rigid first component, which gives the operating part the necessary strength and rigidity and can also withstand greater forces, and a softer second component, which fits well in the hand of the operator and has pleasant haptic properties. Thus, the operating part ensures good force transmission and is nevertheless comfortable for the operator to operate.

[0016] The device can have one or more feet, which ensure that the device stands securely on the base. This is achieved especially well with three feet. The feet can have anti-slip properties to ensure that the device stands securely even when forces are applied to the operating part.

[0017] The slide can be guided in the sleeve in the body. Thus, good guidance of the slide in the body is achieved regardless of the material of the body. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 11 shows a device 10 designed according to the invention with a body 20 and an operating part 30. In addition, a slide 30 can be seen, which is arranged above a tool plate 21 or a tool 60. The slide 30 is here in its working position 30.2, while the operating part 40 is in its second position 40.2. The working area 12 can be seen between the slide 30 and the tool 60. The slide 30 is guided through the body 20 in a sleeve 32 and can be moved linearly toward the tool 60 or away from it. In order to cause a movement of the slide 30, the operating part 40 is moved upward or downward.

[0030] In this embodiment, the operating part 40 itself is composed of two different materials, namely, a first member 44 and a second member 45. The first member is rigid and strong and provides the operating part 40 with necessary strength, and the second member is relatively soft and has a comfortable touch for the operator. Thus, the following operating part 40 can be provided, which should be comfortable to operate at the same time, but is still sufficiently rigid and strong to reliably transmit the applied force.

[0031] Furthermore, a part of a measuring scale 22 is also visible, at which the position of a workpiece can be read or the workpiece can be correctly positioned when the device 10 is used. A projection 24 is also provided at the illustrated measuring scale 22, which projection can be used to abut against the workpiece. Further measuring scales 22 can also be provided in order to position the workpiece even more accurately.

[0032] Finally, it can also be seen that feet 23 are introduced at the bottom into the body 20. These feet ensure that the body 20 stands securely and can have anti-slip properties, whereby even when forces are applied to the operating part 40, the device 10 remains securely standing and can perform good and reliable processing of the workpiece.

[0033] Figure 2The illustration in FIG. 4 shows the structure of the operating part 40 and the interaction with the body 20 and the slide 30 in more detail. It can be seen that an articulated element 43 is provided, which is designed in the manner of a crank lever. In this embodiment, a total of three pivot axes are provided: a first pivot axis 41 between the operating part 40 and the articulated element 43, a second pivot axis 25 between the pivot element 43 and the body 20, and a third pivot axis 33 between the slide 30 and the operating part 40. Through the interaction of these three pivot axes 41, 25, 33, on the one hand, the pivoting movement of the operating part 40 is transmitted to the linear movement of the slide 30, but on the other hand, it is also ensured that the force applied when pivoting the operating part 40 is well converted and transmitted to the slide, so that with relatively small manually applied forces, large forces can also be applied to the tool 60 and the countertool 61, and thus more difficult or slow punching or riveting processes can also be performed. Due to the design and arrangement of the shaft, a large number of riveting and drilling processes that cannot be performed using conventional devices can thus also be carried out by operators with less physical strength.

[0034] Furthermore, the stop 11 can be seen, which is arranged on the body 20 and interacts with a counter-stop 42 on the operating part 40 in the illustrated second position 40 . 2 of the operating part 40 and thus determines both the exact position of the second position 40 . 2 of the operating part 40 and also the working position 30 . 2 of the slide 30 .

[0035] Finally, it can be seen that three measuring scales 22 are arranged indirectly or directly on the body, which can be used to accurately determine the position of the workpiece. Partly, the measuring scales 22 are arranged on the body 20 in a movable manner and in a releasably fixable manner, so as to also fix the projection 24 in the exact position and to facilitate the orientation of the workpiece. The large number of measuring scales 22 makes it easy to orient and position the workpiece to be processed.

[0036] from Figure 3 The exact structure of the device 10 can be seen from the exploded view in FIG. The structure of the operating part 40 is shown here, which comprises two parts consisting of a first component 44 and one part consisting of a second component 45. The structure of the slide 30, which is arranged in a sleeve 32 in the body 20, and the structure of the mating tool 61 can also be seen here. The articulated element 43 with the first pivot axis 41 and the second pivot axis 25 and the third pivot axis 33, which acts on the slide 30 and connects it to the operating part 40, can also be seen.

[0037] The stop 11 is arranged at a stop screw 13. The stop screw is in turn guided in a bushing 14, which is configured as a threaded bushing with an internal thread. The bushing 14 can also be introduced into the main body 20 regardless of the material of the main body 20 itself. By means of the embodiment as a stop screw 13 and a bushing 14, a stepless manual adjustment of the stop 11 can be achieved in a simple manner. The stop screw 13 has knurling on the outside of its head in order to simplify manual adjustment.

[0038] Furthermore, it can be seen that a tool 60 is inserted into or placed on the tool plate 21. The tool 60 can be replaced by an operator in order to adapt it to the respective application.

[0039] One of the three measuring scales 22 shown can be completely removed from the body 20. A projection 24 is provided at this measuring scale 22, which itself comprises a further measuring scale 22. The movable measuring scale can be detachably fastened to the body 20 in order to adjust the distance of the projection 24 from the slide 30. The third measuring scale 22 is fixedly mounted on the body 20. By means of a large number of measuring scales 22, the workpiece to be machined can be precisely oriented towards the tool 60 and the counter tool 61.

[0040] from Figure 4 The structure of a possible fixing device 50 can be seen in more detail in FIG. Here, a roughly U-shaped clamp 51 is provided, which can, for example, surround the edge of a plate, such as a table top, a shelf bottom, etc. when fixed. Here, one leg 52 of the U-shaped clamp 51 can be fixed to the device 10 itself, for example to the body 20, while the other leg 53 acts on the bottom of the plate and can be fixed to the side of the plate facing away from the device 10. For fixing, a fixing device 54 is also provided, which is a screw in this case, which passes through the other leg 53 of the U-shaped clamp 51. As the head of the screw, a handle is used for the fixing device 54, which can be easily actuated manually. On the side of the fixing device 54 facing away from the handle, a counter plate 55 is also provided, which is supported on the plate when fixed and thus fixes the device 10 on the plate to prevent movement. A protective cover is not shown here, which can still be arranged between the counter plate 55 and the plate in order to protect the plate from damage, such as scratches or indentations caused by the counter plate 55.

[0041] Figures 5 to 7 The movement of the operating part 40, the slide 30 and the joint element 43 is shown. Figure 5, the operating part 40 is in its first position 40.1 and the slide 30 is in its release position 30.1. The articulated element 43 is arranged almost vertically and the first pivot axis 41 and the second pivot axis 25 are arranged approximately vertically one above the other. The third pivot axis 33 is arranged spaced apart from the other two pivot axes. If the operating part 40 is now pivoted, the three pivot axes 41, 25 and 33 are arranged as shown in FIG. Figure 6 The movement shown in . By arranging the pivot axis and guiding the slide 30 through the sleeve 32, the pivoting movement of the operating part 40 is converted into a linear movement of the slide 30. By designing the joint element 43 as a crank lever, a suitable force transmission of the pivoting movement of the operating part 40 is achieved, so that the force to be applied by the operator is smaller than that of a direct force transmission. Finally, Figure 7 The operating part 40 is shown in its second position 40.2 and the slide 30 in its working position 30.2. The counter tool 61 in the slide 30 is moved maximally in the direction of the tool 60, and the workpiece arranged in the working area 12 is processed by the tool 60 and the counter tool 61. Due to the interaction of the stop 12 and the counter stop 42, the operating part 40 cannot be pivoted further downwards.

[0042] from Figure 8 and Fig. 9 The function of the stop 11 and the counter stop 42 can also be seen in FIG. The stop 11 is arranged here on the stop screw 13, which is located in the bushing 14. The bushing 14 has an internal thread here for the external thread of the stop screw 13. Figure 8 In the second position 40.2 of the operating part 40, the stop screw 13 is screwed into the bushing 14 to the maximum extent. The second position 40.2 of the operating part 40 is pivoted downward to the maximum extent, and the working position 30.2 of the slide 30 is also pivoted downward to the maximum extent, so that the mating tool 61 moves to the maximum extent towards the tool 60. Fig. 9 In the second position 40.2, the stop screw 13 is screwed out of the bushing 14 to the maximum extent. The operating part 40 is also in its second position 40.2, but the degree of pivoting of the operating part is smaller than that of the second position 40.2. Figure 8 2, the distance between the mating tool 61 and the tool 60 is at its maximum. Figure 8 and Fig. 9 Between the two positions shown in FIG. 1 , all possible variations are conceivable, depending on how far the stop screw 13 is screwed into the bushing 14 .

[0043] In addition, Figure 8 and Fig. 92 shows a receptacle 26 into which a leg 52 of a U-shaped clamp 51 can be introduced in order to fix the fastening means 50 on the device 10. If no fastening means 50 is provided, the receptacle 26 remains empty.

[0044] at last, Fig.10 The tool plate 21, on which the tool 60 has been placed, and the tool receiving part 31 are shown, which has a counter-tool 61 introduced therein. The tool 60 and the counter-tool 61 are oriented relative to each other. If, for example, a rivet is now to be processed at a workpiece, the rivet or the two parts of the rivet are placed at the tool 60 and / or the counter-tool 61 and the workpiece to be processed is arranged between them. After this, the slide 30 is brought into its working position 30.2 by operating the operating part 40 and the rivet is arranged at the workpiece. For different rivets and holes, different tools and counter-tools are used, which can be arranged accordingly at the device.

[0045] Finally, it should be pointed out that the embodiments shown here are merely exemplary implementations of the present invention. The present invention is not limited thereto. On the contrary, further modifications and limitations may be made.
