Abstract
Description
Technical Field
[0001] The present invention is mainly a pressure device, and more particularly a pressure device for applying pressure to the painting surface of an oil painting at a deformed part of the substrate. Prior Technology
[0002] Oil paintings commonly use canvas, wood, paper, and particleboard as substrates. Canvas materials can be broadly categorized into linen, half-linen, imitation linen, cotton, and various synthetic fibers. Substrate deformation is a common form of deterioration in oil paintings. The main causes of substrate deformation can be broadly divided into inherent canvas defects and environmental and human influences.
[0003] Specifically, problems with the canvas itself may stem from issues such as uneven canvas material and tension, uneven undercoating, structural problems between the canvas and the inner frame, or differences in the expansion and contraction rates of the paint layer and the canvas. On the other hand, environmental and human influences may also play a role, such as changes in temperature and humidity, improper long-term storage, deformation of the inner frame or damage to the supporting structure, transportation and external impacts, insect infestation, or mold growth. Therefore, when the substrate of an oil painting becomes deformed and affects the structure and safety of the artwork, a restorer will smooth out the deformed areas (wrinkles) to restore the stability of the painting. Summary of the Invention
[0004] The conventional method for restoring deformation of the substrate of an oil painting involves applying moderate pressure to the deformed area using heavy objects such as sandbags or metal blocks (not too heavy, otherwise it will damage the painting) to allow the deformation to gradually return to a flat state. However, during the pressure-leveling process, the restorer needs to repeatedly remove the heavy object from the substrate and observe whether the deformed area has been leveled. If it is not leveled, the heavy object must be placed back on the deformed area. Therefore, it requires a significant time investment for the restorer to observe the leveling process, and the repeated removal and replacement of the heavy object may also damage the painting.
[0005] The purpose of this invention is to provide a pressure device for the base material of an oil painting, which can be used to pressurize and level deformed areas of the base material.
[0006] To achieve the above objectives, the present invention provides a pressure application device for a drawing area, comprising: a substrate having a first surface and a second surface disposed opposite to each other, the first surface having a handle; a display disposed on the first surface; a pressure sensing module having a plurality of pressure sensors disposed at intervals on the second surface, the pressure sensors being used to sense pressure changes and output a pressure signal; and a controller electrically connected to the display and the plurality of pressure sensors of the pressure sensing module, the controller being used to control the display to generate a color change in a unit pixel at a relative position to the pressure sensor that outputs the pressure signal.
[0007] In some embodiments, the drawing layout pressing device of the present invention may further include at least one transparent block, which is removably disposed on the first surface.
[0008] In some embodiments, the substrate has several magnetic wires inside, and the transparent block has a magnetic element inside, through which the transparent block magnetically attracts the magnetic wires to bond to the first surface.
[0009] In some embodiments, the magnetic element is a magnetic ring.
[0010] In some embodiments, the display is recessed to form a cutout area, and the handle is disposed on the first surface exposed in the cutout area.
[0011] In some embodiments, the substrate is an acrylic sheet.
[0012] In some embodiments, the pressure sensor is a thin-film pressure sensor.
[0013] The canvas partial pressing device of the present invention has the following characteristics: it can sense the pressure change when the canvas partial pressing device comes into contact with the canvas using several pressure sensors in the pressure sensing module, and control the display to produce a color change at the unit pixel of the pressure sensor that outputs the pressure signal. This allows the restorer to more intuitively confirm whether the wrinkles on the canvas have been flattened by observing the color change of the unit pixel on the display. This reduces the time required for repeated observation and reduces the probability of damage to the canvas during the flattening process. Simple Explanation of the Diagram

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are mainly simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention. Therefore, only the elements related to the present invention are marked in these drawings, and the elements shown are not drawn according to the number, shape, size ratio, etc. of the implementation. The actual specifications and dimensions of the implementation are a selective design, and the layout of the elements may be more complex.
[0016] The following descriptions of the embodiments are with reference to the accompanying drawings, illustrating specific embodiments in which the invention may be practiced. Directional terms used in this invention, such as "up," "down," "front," and "back," are merely directional references to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of this application, and not for limiting this application. Furthermore, in this specification, unless explicitly stated otherwise, the word "comprising" will be understood to mean including the stated elements, but not excluding any other elements.
[0017] Please refer to Figure 1, which is a perspective view of the first embodiment of the layout pressure device 10 of the present invention. It includes: a substrate 1, a display 2, a pressure sensing module 3 and a controller 4, wherein the display 2, the pressure sensing module 3 and the controller 4 are respectively disposed on the substrate 1, and the display 2 and the pressure sensing module 3 are respectively electrically connected to the controller 4.
[0018] The substrate 1 has a first surface 11 and a second surface 12 disposed opposite to each other, wherein the first surface 11 is provided with a handle 13. In this embodiment, the substrate 1 can be an acrylic sheet.
[0019] The display 2 is disposed on the first surface 11. In this embodiment, the display 2 can be a liquid crystal display (LCD). Specifically, the display 2 can be recessed to form a cutout area 21, so that the handle 13 can be disposed on the first surface 11 exposed in the cutout area 21.
[0020] The pressure sensing module 3 has several pressure sensors (not shown in the figure), which are spaced apart on the second surface 12. These pressure sensors are used to sense pressure changes and output a pressure signal. In this embodiment, the pressure sensor can be a thin-film pressure sensor (FSR).
[0021] Referring also to Figure 2, the controller 4 controls the display to produce a color change at a unit pixel U relative to the pressure sensor that outputs the pressure signal. In this embodiment, the controller 4 can be an Arduino development board and can be disposed on the side of the substrate 1. Specifically, the unit pixel U can be set according to the diameter of the sensing part of the pressure sensor. Assuming the diameter is 5 mm, the unit pixel U can be set to 20*20 pixels, but it is not limited to this.
[0022] Please refer to Figure 2, which is a diagram illustrating the use of the first embodiment of the layout pressing device 10 of the present invention. First, the substrate material of the canvas C deforms to form wrinkles W. Then, the layout pressing device 10 of the present invention is placed on the wrinkles W to apply pressure to them. Next, most of the unit pixels U on the display 2 change color, while only a small number of unit pixels U do not change color. This is because the pressure sensors at the positions corresponding to the unit pixels U that do not change color do not sense any pressure change. The reason for this is that the weight of the layout pressing device 10 of the present invention is insufficient to flatten the wrinkles W. In other words, if all the unit pixels U on the display 2 change color, it means that all the pressure sensors sense a pressure change, that is, the weight of the layout pressing device 10 of the present invention is sufficient to flatten the wrinkles W. In this way, the restorer can directly observe the color changes of the pixels on the monitor 2 to confirm whether the wrinkles W on the canvas C have been flattened, saving the time required for repeated observation and reducing the chance of damage to the canvas C during the flattening process.
[0023] Please refer to Figure 3. The second embodiment of the layout pressure device 10 of the present invention, compared with the first embodiment, may further include at least one transparent block 5, which is removably disposed on the first surface 11.
[0024] Please refer to Figure 3, which shows the usage of the second embodiment of the drawing area pressing device 10 of the present invention. Firstly, the weight of the drawing area pressing device 10 is insufficient to flatten the wrinkle W. Therefore, the transparent block 5 is further placed on the drawing area pressing device 10 at the position corresponding to the wrinkle W to increase the overall weight and flatten the wrinkle W. This avoids the situation where the drawing area pressing device 10 is insufficient in weight to flatten the wrinkle W.
[0025] Please refer to Figure 4, which shows another usage scenario of the second embodiment of the layout pressing device 10 of the present invention. The display 2 has several unit pixels U that do not produce color change, meaning the canvas C has several folds W. Therefore, it is necessary to simultaneously place multiple transparent blocks 5 on the layout pressing device 10 at positions corresponding to these folds W to simultaneously flatten them. Furthermore, when the pressure applied by a single transparent block 5 is insufficient to flatten a fold W, multiple transparent blocks 5 can be stacked to increase the overall weight.
[0026] Please refer to Figure 5, which is a side sectional view of the third embodiment of the canvas pressing device 10 of the present invention. In this embodiment, compared with the second embodiment, the substrate 1 has several magnetic wires 14 inside, and the transparent block 5 has a magnetic element 51 inside. Therefore, the transparent block 5 can be magnetically attracted to the magnetic wires 14 through the magnetic element 51 to be bonded to the first surface 11. For example, the magnetic element 51 can be a magnetic ring. This prevents the transparent block 5 from shifting on the canvas C, thereby avoiding damage to the canvas C.
[0027] As described above, the canvas partial pressing device of the present invention can sense the pressure change when the canvas partial pressing device comes into contact with the canvas using several pressure sensors in the pressure sensing module, and control the display to produce a color change at the unit pixel relative to the pressure sensor that outputs the pressure signal. This allows the restorer to more intuitively confirm whether the wrinkles on the canvas have been flattened by observing the color change of the unit pixel on the display. This reduces the time required for repeated observation and the probability of damage to the canvas during the flattening process.
