    专利说明:

    The invention relates to a device for 3D display of objects, with a plurality of pins, which are arranged parallel to each other in a frame and adjustable in its longitudinal direction.
    Due to the individual adjustment of the pins in respective elevations can be obtained by the upper pin faces a three-dimensional surface in relief.
    Such a device is known from US 2014/0120195 A1, in which a plurality of pins with a quadrangular cross-section are arranged parallel to one another in a fixed frame. The pins are positioned by a single control and fixed by means of pushing on individual rows of pins cross bars by friction. Furthermore, a support structure can additionally be used within the pin arrangement. The disadvantage here is that a gap is given by the support structure within the pin assembly, and thus no dense arrangement of pins is given. In addition, the pins in the regions of the support structure must be reduced in cross section, which makes the structure of the pins vulnerable to fractures.
    The US 5717423 A shows a device for generating a three-dimensional display, wherein pins are arranged, for example, quadrangular cross-section within a frame. The pins are laterally adjacent to each other and are driven individually by spindle drives. Through these spindles, the pins are held in their respective high altitude self-locking. A disadvantage of this device is that the fact that each individual pin is positioned by its own spindle (which may be susceptible to interference), a minimum cross-sectional size of the pins is specified because the spindle a certain minimum cross-section is required. Furthermore, this design is complex and expensive.
    EP 0857544 A2 shows a somewhat different device, namely a holding device for workpieces, which has in a frame a plurality of circular cross-section, parallel to each other horizontally aligned and laterally adjacent to each other dowel pins. These pins are enclosed for example by a circular frame and are individually displaceable in their main extension direction. By a fixing device, the pins are pressed together within the frame and thereby fixed.
    Object of the present invention is to provide a device of the type mentioned, with which, compared to the prior art, an improved design can be realized. The invention has the particular object of designing a frame enclosing the pins in such a way that uniform pressure is exerted on the pins from all sides of the frame and thereby in a simple manner either fixing the pins without undesirably moving pins into other height settings can be achieved, or by a precisely metered pressure on the pins, a displacement of the pins is made possible, the pins are still held in position.
    This object is achieved by a device for the 3D representation of objects as stated in claim 1. Preferred embodiments are specified in the dependent claims.
    The present apparatus for the 3D display of objects accordingly comprises a frame that is inwardly compressible, the pins being thus laterally pressurizable by the frame; The frame can consist of several frame parts and / or of a flexible material, and it is disposed within an outer clamping device.
    Thus, the frame assembly for holding or fixing the longitudinally adjustable pins is designed such that the frame, e.g. can consist of several frame parts, but also of flexible material, from an outer
    Clamping device is enclosed. Thus, the frame can be placed in a simple and particularly effective way laterally under pressure to press the pins laterally against each other and thus to hold them by friction. Furthermore, the pins can be chosen to be particularly small in their cross-section, since they do not like e.g. be held by a spindle in the pen in the set height at US 5717423 A. The arrangement of the pins can be very compact and narrow, since the tension or the pressure is exerted exclusively on the frame.
    To exert pressure on the frame, it is advantageous if the clamping device has outer stiff clamping parts. As a result, sufficient, and in particular uniform, pressure can be exerted on the entire frame from all sides. In addition, this design is particularly easy to use and inexpensive to manufacture.
    In order to set the frame by the outer clamping parts in a particularly simple, efficient way under pressure, it is advantageous if the clamping parts by means of screws against the frame can be tensioned. This allows the fixation of the pins within the frame done evenly and firmly. In addition, the fixation of the clamping device by screws is mechanically simple, and a fine, local adjustment is possible. Through the screws it is possible to separately adjust the applied pressure, e.g. also possible tolerances in the frame construction can be compensated.
    In a further preferred embodiment, the outer clamping parts are clamped by means of a tension band against the frame. Thereby, the fixation of the pins can be achieved in a particularly simple and fast manner. It is also advantageous if the outer clamping parts are formed by arranged at corners of the frame corner angle. As a result, the pressure force can be evenly distributed on the four sides of the frame and thus an optimal compression can be achieved. In addition, the resulting gaps on the longitudinal and transverse sides of the frame give a certain amount of leeway when the frame is pulled together.
    In order to easily position the strap around the frame, it is advantageous if the corner parts have a groove for inserting the tension band on the outer circumference.
    Furthermore, it is advantageous if the corner angles of the clamping device have a convex shape on the outside. As a result, an approximately rounded course of the tension band is achieved and brought about a uniform train around the circumference in a simple manner.
    Furthermore, it is advantageous if the frame is substantially selectively connected to the clamping part. Thus, an unwanted separation of the frame can be avoided by the clamping device. In addition, a displacement between the frame and clamping part is counteracted and the entire construction gains in stability. Other ways in which increased stability can be achieved are e.g. the selective bonding of the tension belt with the corner parts or the connection between the hose or the membrane with a fixed frame.
    Preferably, the tensioning device has a pressure medium hose which is arranged outside the frame. With this pressure medium hose can be exercised in a simple manner, a particularly uniform pressure on all sides of the frame.
    In order to ensure a compact and effective pressure distribution, it is also advantageous if the pressure fluid hose is supported on the outside of an outer frame. The pressure medium hose may e.g. be pressurized pneumatically or hydraulically. As a result, the pressure on the pins can be easily adjusted. Instead of a separate pressure fluid hose, a membrane may also be connected to the outside of the frame to form an inflatable chamber between the diaphragm and the frame.
    In order to avoid possible stresses between the frame and clamping device, it is advantageous if a sliding layer is present between the frame and the clamping device. Furthermore, it is advantageous if the frame is made of an elastomer, e.g. Silicone rubber, consists. Thus, even pressure can be applied in a simple manner, and the frame yields slightly when compressed by the tensioning device. As a result, the pins experience an elastic, yet stable and gentle fixation. In addition, small tolerances can be compensated by the elastomer layer.
    A further advantageous possibility is that the frame is formed by a, with a wall directly adjacent to the pins laterally, pressure fluid hose. As a result, the pins are held directly by the pressure fluid hose and compressed. This may make a separate framework unnecessary.
    In order to make the connection between the outermost rows of the pins and the frame as efficient and advantageous as possible, it is favorable if the frame is formed inside with grooves corresponding to the cross section of the pins. Thus, the greatest possible contact and hold between the frame and pins and a particularly stable dense arrangement of the pins can be achieved.
    Since the displacement between the outer (first) row of pins along the frame is in any case difficult, it is advantageous if the outer row of pins are integral with or bonded to the frame and / or longitudinally split pins are attached to the frame , In addition, it is advantageous for a favorable fixation that there is as little empty space as possible between the individual pins.
    It is also advantageous if the pins have a hexagonal cross-section. As a result, unfavorable voids between the pins are avoided and a dense packing is achieved.
    The invention will be explained below with reference to preferred embodiments, to which the invention should not be limited. In detail, in the drawing:
    Figure 1 is a perspective, partially cutaway view of an apparatus for 3D representation of objects, with a plurality of pins, which are arranged parallel to each other in a frame and adjustable in its longitudinal direction.

    10A-10L show different embodiments of the frame with different pin cross-sections, different grooves within the frame and different corner region roundings of frames.
    1 and 2 show a device 1 for 3D representation in a partially cutaway view or in a horizontal section, with a plurality of pins 2 in a generally rectangular frame 3 arranged parallel to one another and in their longitudinal direction (FIG. ie height) are individually adjustable, cf. in particular Fig. 1. The frame 3 made of an elastomer, e.g. Silicone rubber, may consist is disposed within a clamping device 4, which has a complete frame 3 comprising the rigid, outer clamping part 5, the pressure to apply to four inner, in cross-section C or. U-shaped clamping profiles 6 is used. The field of pins 2 may be defined by means such as e.g. Prior art pin driver (see, e.g., US 2014/0120195 A1) is placed in a 3D shape, after which the frame 3 is compressed inwardly, i. is pressurized by means of the tensioning device 4, e.g. by means of screws 7 which are fastened to opposite sides of the frame 3 in the same number. As a result, the pins 2 are fixed in position. In order to avoid possible stresses between the frame 3 and the clamping device 4, between the frame 3 and the clamping device 4 a - not shown in detail in the drawing - sliding layer can be attached. Any tolerances in the pins 2, the construction of the frame 3, the clamping device 4 and / or the rigid outer clamping part 5 can be compensated by a separate adjustment of the screws 7. The outer row of pins 2 can also be integral with or glued to the frame 3, since the outer row of pins 2 is difficult to move anyway on a frame 3 made of elastomer. In addition, this design also offers advantages in terms of manufacturing and stability.
    FIG. 3 and FIG. 4 show an alternative embodiment of the device 1 for 3D representation in a partially cutaway view or in a plan view, wherein a plurality of pins 2 in a rectangular frame 3 is compressed by means of a tension band 8. In this embodiment, corner brackets 9 are provided as outer clamping parts, which are arranged at the four corners of the frame 3. The tension band 8 is placed around the entire frame construction, consisting of frame 3 and the tensioning device 4 including corner angle 9 and can be closed by a conventional tension lock 10.
    Because the clamping parts are designed as corner angles 9, pressure can be exerted selectively and uniformly on the corner regions of the frame 3. At the same time remains through the gap 11 on the four sides of the frame 3 enough room for compression, and it is avoided that the corner angle 9 hinder the compression by mutual contact. The corner pieces 9 also have a groove 12 (see Fig. 3) for inserting the tension band 8, which prevents the tension band 8, e.g. slipped during the tensioning process. Through the grooves 12, the clamping band 8 remains in position, thereby enabling easy and uncomplicated closing and opening of the
    The tensioning strap 10 also has due to the corner angle 9 in the four corner regions of the frame 3, an at least partially convex shape 13. This can be achieved in a simple manner over the entire circumference of the frame 3, a uniform tensile stress. In order to avoid an unwanted separation of the frame 3 of the clamping parts 6 after loosening the clamping band 8, the frame 3 and the clamping parts 6 may be adhesively bonded at points.
    FIGS. 5 and 6 show a further alternative embodiment of the apparatus 1 for 3D representation in a partially cutaway oblique view or in a plan view. Here, the tensioner 4 is defined by a pressure medium hose 14 and an outer fixed tension member in the form of an outer (support) frame 15, e.g. formed as a fixed steel frame 15 which is arranged outside of the frame 3. The pressure medium hose 14, which surrounds the entire - here again rectangular - frame 3 continuously, takes over the task of pressurization as the screws 7 in Fig. 1 and 2 or the clamping band 8 in Fig. 3 and 4. With the help of the outer frame 15 can be exercised by eg pneumatic or hydraulic pressurization of the pressure medium hose 14 pressure on the inner frame 3 and thus also on the pins 2. In this way, the pressure on the pins 2 can be adjusted as desired. In this embodiment, the frame 3 and the pressure fluid hose 14 are integrally formed, which additionally simplifies the entire frame tensioning device.
    The pneumatic or hydraulic pressurization of the pressure medium hose 14 can take place via a connection 16 (with valve).
    Fig. 7 shows an alternative embodiment of a frame 3 in plan view, this, as well as the pins 2, has a round cross-section. Due to the round cross-section of the frame, the inner clamping profiles 6 of four (according to FIG. three (or two) are reduced.
    Fig. 8 shows a further embodiment of the frame 3 in plan view, wherein the cross section of the frame 3, and here also the cross section of the pins 2, have a hexagonal shape.
    Due to the hexagonal cross section of the pins 2, these can rest against each other without voids between them and thus a dense arrangement of the pins 2 can be achieved. Due to the shape of the frame 3, six inner clamping profiles 6, which bear against the respective six sides of the frame 3, are provided.
    9 shows in the subfigures 9A, 9B and 9C various profile variants of the pressure medium hose 14 (compare FIGS. 4 and 5). In this case, an inner frame 3, a pressure medium hose 14 and a solid outer steel frame 15 are shown as separate parts in Fig. 9A.
    Fig. 9B shows a modification of the arrangement according to Fig. 9A, wherein a pressure medium hose 14, which exerts the pressure force inwardly, between a fixed outer steel frame 15 and an inner movable, e.g. divided steel section 17 is arranged on the frame 3.
    In Fig. 9C, instead of the pressure medium hose 14, a membrane 18 is provided which is fixedly connected to a fixed outer steel frame 15 and thus forms a pressure chamber 19. In this case, the connection between the steel frame 15 and the membrane 18 can be made e.g. positive (by anchoring) and / or non-positively (for example, bonding) done. This design has the advantage of being resource efficient and compact.
    FIGS. 10A-10L illustrate various variants of how the frame 3 or the abutment between the frame 3 and the pins 2 and the cross section of the pins 2 can be formed.
    10A-10D show pins 2 with different cross sections known per se. While FIG. 10A and IOC show pins 2 of round or square cross-section, respectively, the pins 2 are formed with a hexagonal or triangular cross-section as shown in FIGS. 10B and 10D. The latter, like those according to FIG. 10C, are advantageous, above all, by the avoidance of empty spaces 20 (see FIG.
    Furthermore, FIG. 10E shows an arrangement of round cross-section pins 2, the outer (first) row (left in FIG. 10E) being provided in the form of longitudinally divided pins 21 on the frame 3.
    In Fig. 10F, an outer row of pins 2 'is formed integrally with the frame 3. Thereby, a continuous transition from the pins 2 and the frame 3 can be achieved.
    As shown in FIG. 10G, as an alternative to FIG. 10F, the frame 3 has grooves as in FIG. 10B, but in this embodiment, unlike in FIG. 10B, the pins 2 have a round cross-section. The size of the voids 20 at the inner edges of the frame 3 is reduced by this shape of the grooves compared to FIG. 10F, which can have a positive effect on the compression.
    Fig. 10H shows a similar embodiment of the grooves within the frame 3 as Fig. 10G. The grooves are formed in contrast to the grooves in Fig. 10G is not angular, but rounded. Thus, the frame 3 can cling tightly to the outer rows of pins 2 through the round grooves. In addition, this embodiment is particularly simple and stable to produce.
    FIGS. 10I-10L show, starting from the embodiment according to FIG. 10G, frames 3 with differently pronounced rounding off of the regions in the corners. In detail, Fig. 101 shows that the arrangement of the pins 2 within the frame 3 converges relatively sharply in the corner. 10K shows a somewhat obtuse angle in comparison, whereas FIG. 10L already shows a clear rounding of the pin field 2 in the corners of the frame 3. Depending on the rounding of the corners, the power transmission to the frame 3 can be improved. Especially in the embodiments with the tensioning belt 8 according to FIGS. 3 and 4 and the pressure medium hose 14, too small radii at the corners can become problematic.
