Abstract
Description
Transparent 5-sided bending tube for canvas
[0001] The present invention relates to a transparent five-sided bending frame for a canvas for storing a work of art, and more particularly, to a transparent frame for a canvas for storing a work of art, characterized in that it comprises a cover part having a structure in which a portion of each corner is removed and the corner part is bent; and a panel part that supports the work of art while being combined with the cover part.
[0002] The "transparent picture frame" that is currently in general use is individually manufactured to fit the artwork in the "transparent picture frame" in order to enhance the commercial value of the artwork when stored, safely displayed, and exhibited by the artist. In the current common technology and commercial case, the artwork is placed on a "wood plywood panel structure," and a lid-type cover is produced by cutting and bonding a synthetic transparent resin panel on five sides, and then combined with the wood plywood panel on which the artwork is placed, thereby widely using the "transparent picture frame." However, the present invention relates to a technology that allows a five-sided three-dimensional structure to be made into a cover by forming the front cover part with a single panel without cutting and bonding the five-sided structure.
[0003] In general, works of art such as oil canvas, acrylic canvas, watercolor, canvas, frame, and photograph are vulnerable to everyday contamination such as dust, fingerprints, and foreign substances, and are especially vulnerable to damage or breakage due to impact and contamination during display and storage, so in the art field, there has been a demand for framed canvases for storage and display.
[0004] In the case of existing canvas framers, each piece (five sides) was cut into a square shape and joined together using adhesive (bond) to create a square frame. This approach presented the problem of the sharp corners being aesthetically unsightly and opaque.
[0005] Additionally, when each part was folded and joined together to create a streamlined corner, a problem arose in which collisions occurred between the parts near the vertices due to the thickness of the material, such as acrylic.
[0006] To solve the above problem, the inventor proposes a transparent frame for a canvas for storing art works.
[0007] The reason for using "frames or transparent frames, etc." for completed paintings in art works is that it does not damage or belittle the artistic value of the work, but rather aims to highlight the artistic value of the work and its superior commercial value when exhibited, and it has the advantage of pursuing stability at the same time, so there is a demand for using "frames or transparent frames" even though they are expensive.
[0008] This can increase the value of the work by displaying and ensuring safety for the cost, so the better the material and finishing, the more the cost increases and this can be accepted.
[0009] In terms of enhancing the value of these works of art, the newly invented "5-sided bending transparent frame" has structural and aesthetic superiority that makes it far more marketable and artistic than the existing "5-sided cutting and bonding transparent frame."
[0010] The present invention may have the following purposes.
[0011] The purpose of the present invention is to provide transparency and aesthetics by making the four corners of the surface streamlined while not colliding with each other near the vertices.
[0012] In addition, an object of the present invention is to maintain the structural stability (maintaining 90° right angles at all four corners) of a transparent tube for canvas by dynamically determining the size of a groove near a vertex based on the thickness of the cover portion.
[0013] In addition, the purpose of the present invention is to protect the artwork from physical damage such as contamination, external impact, and breakage during display and storage, to enhance the artistic value of the artwork and the commercial value of the artwork during display, and to effectively convey the unique expression of the artwork to the gallery.
[0014] According to one embodiment of the present invention, a transparent tube frame for a canvas for storing a work of art is provided, characterized in that it includes a cover part having a structure in which some areas are removed from the four corners and the corner parts are bent; and a panel part that supports the work of art while being combined with the cover part.
[0015] According to the present invention, the following effects are achieved.
[0016] According to the present invention, the four-sided corners are made streamlined, but do not collide with each other near the vertices, and the four-sided transparency is secured through streamlined curve processing, thereby significantly enhancing the displayability and viewingability of the art canvas work being displayed.
[0017] In addition, according to the present invention, there is an effect of maintaining the structural stability (maintaining a 90° right angle) of the transparent tube for canvas by dynamically determining the size of the groove near the vertex based on the thickness of the cover portion.
[0018] In addition, according to the present invention, it is possible to protect the artwork from physical damage such as contamination, external impact, and breakage during display and storage, and it is effective in enhancing the artistic value of the artwork and the commercial value of the artwork during display, and effectively conveying the unique expression of the artwork to the gallery.

Like reference numerals in the drawings designate the same or similar functionality throughout the several aspects.
[0027] Hereinafter, in order to enable a person having ordinary skill in the art to easily practice the present invention, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
[0028] FIG. 1 is a drawing showing the bonding relationship between a cover part, a panel part, and a work according to one embodiment of the present invention.
[0029] The present invention relates to a transparent five-sided bending frame (10) for a canvas for storing a work of art (300), which is used for displaying the work of art, etc., and the (art) work of art (300) may include an oil painting canvas, an acrylic canvas, a watercolor painting, a canvas, a frame, a print, a photograph, etc.
[0030] The transparent tube (10) for canvas of the present invention may include a cover part (100) and a panel part (200), and the cover part (100) and the panel part (200) may be connected to each other through a screw (piece) connection described later while wrapping the work (300) located inside.
[0031] For reference, the cover part (100) may be composed of a material such as (transparent) acrylic resin, (transparent) synthetic resin, etc., and the panel part (200) may be composed of wood, synthetic resin, etc. Of course, it may also be composed of other materials.
[0032] FIG. 2 is a drawing showing a cover portion unfolded according to one embodiment of the present invention.
[0033] Referring to Fig. 2, the cover part (100) may correspond to a structure (five sides) composed of four corner parts (111, 112) centered on a central part (110) after some areas are removed from each corner based on the entire rectangular area. Here, some areas may correspond to a rectangular shape. In addition, each corner part (111, 112) of the cover part (100) may have a structure that can be bent.
[0034] That is, the cover part (100) can be composed of a central part (110) of a square shape, and a first-first corner part (111-1), a second-first corner part (112-1), a first-second corner part (111-2), and a second-second corner part (112-2) sequentially on each side based on the central part (110).
[0035] In the drawing, the central part (110) is depicted as having a long rectangular shape, and the first-first corner part (111-1) and the first-second corner part (111-2) are longer than the second-first corner part (112-1) and the second-second corner part (112-2). However, in some cases, the shape may be formed in the opposite direction, with a long rectangular shape. In addition, each corner part (111, 112) may have the same length and be in the shape of a square.
[0036] For convenience of explanation, the following description will assume and describe a rectangular shape in which the central part (110) is longer in width than in height (Fig. 2).
[0037] In the case of a (transparent) frame for existing canvas, each corner part and center part can be manufactured into a box shape (square frame) by being separated and joined using adhesive, etc.
[0038] In this case, the boundary between the center part and the corner part can be angular and opaque (the cut surface and the cut surface are added and bonded using an adhesive).
[0039] On the other hand, the cover part (100) of the present invention is formed by continuously using the central part (110) and each corner part (111, 112) by bending (folding) five sides of one panel without cutting, thereby forming a five-sided structure, and each corner part (111, 112) can be bent (folded) based on the central part (110).
[0040] When manufacturing a transparent tube (10) for a canvas of the present invention, the corner parts (111, 112) can be bent in one direction while applying heat to the boundary between the corner parts (111, 112) and the center part (110).
[0041] In this case, the boundary between the central part and the corner part can be maintained in a transparent state while forming a streamlined shape. In other words, it provides an aesthetic sense by maintaining transparency compared to the existing transparent frame (10) for canvas, which can have a great advantage in terms of storing the work (300).
[0042] However, according to one embodiment of the present invention, when bending the corner parts (111, 112), the thickness of the (acrylic plate material) itself of the cover part (100) made of (transparent) acrylic, (transparent) synthetic resin, etc. (ex. 1.5 mm, 1.8 mm, 2.0 mm, 2.8 mm, 3.0 mm, 4.0 mm, 5.0 mm, 7.0, 8.0 mm, etc.) may cause a collision between the corner parts near the vertex of the center part (110).
[0043] If only one corner part (ex. 111-1) is bent, there is no problem, but if two corner parts are bent, including the corner part on the side (ex. 112-1), a collision occurs between the two corner parts (111-1, 112-1) due to the thickness of each corner part (111-1, 112-1), and both corner parts (111-1, 112-1) cannot be properly bent at 90°.
[0044] To solve this problem, the transparent tube (10) for canvas of the present invention may include a groove between adjacent corner parts. Here, the groove may correspond to a circular shape (see (a) of FIG. 2) or a round shape (see (b) of FIG. 2), and further, the size of the groove may be determined by the thickness of the cover part (100). For reference, the thickness of the cover part (100) will be the same for both the central part (110) and the corner parts (111, 112).
[0045] Let's take a closer look at each home with reference to Figures 3 and 4.
[0046] For convenience of explanation, the thickness length of the cover part (100) below can be assumed to be s (ex. 1.5 mm, 5 mm, etc.).
[0047] FIG. 3 is a drawing specifically showing a groove of a cover part according to one embodiment of the present invention.
[0048] Referring to FIG. 3 according to one embodiment of the present invention, the groove may have a circular shape, and the thickness length of the cover part (100) may correspond to s. The circular groove may include a square inside with one side having the thickness length (s), and the diameter of the circular groove may be greater than or equal to s.
[0049] That is, the size of the diameter of the circular groove is limited to be greater than or equal to the diagonal length s of the square so as to include a square inside with a side length of s. This is because the larger the groove size, the lower the probability of collision between the corner parts (111, 112). However, if the groove size becomes excessively large, a large hole may exist near the vertex of the cover part (100) in a bent state, which may cause aesthetic discomfort when appreciating the work (300).
[0050] We will look at the location of the circular groove again later.
[0051] FIG. 4 is a drawing specifically showing a groove of a cover part according to another embodiment of the present invention.
[0052] Referring to Fig. 4, the groove may have a round shape, and the thickness length of the cover part (100) may correspond to s. The round-shaped groove may have a round (streamlined) structure (s + α) having a length longer than the diagonal (s) of a square having the thickness length (s) as one side. In some cases, the round-shaped groove may correspond to 1 / 4 of a circle having the thickness length (s) as a radius, and thus the groove length of the round structure may also correspond to 1 / 4 of the circumference (2 s).
[0053] Ultimately, the length of the round-shaped groove is set to be longer than the diagonal of the square (s), but because it has a round structure, it is set to be shorter than the length of two sides of the square (2s).
[0054] The aforementioned circular or round-shaped grooves exist in total at four points near each vertex of the central part (110), and may correspond to vertices where three corners meet in the cover part (100) in a bent state.
[0055] Accordingly, when an impact is applied to the transparent tube (10) for canvas, the groove located near the vertex may be easily damaged. To solve this problem, in the present invention, additional heat treatment (e.g., using a soldering iron, heat dryer, etc.) may be added to the groove (circular or round shape) during the manufacturing process, and the heat-treated groove may have higher strength and may not be damaged even by impact, etc.
[0056] FIGS. 5 to 7 are drawings showing the process of folding the cover portion and the rear structure when folded according to one embodiment of the present invention.
[0057] Specifically, FIG. 5 shows the process of folding the cover part (100) (arrow direction), and each corner part (111, 112) can be bent to create a square frame shape. In addition, FIG. 6 shows the appearance when the cover part (100) is bent to create a square frame shape.
[0058] In addition, when the direction in which the work (300) is viewed in the transparent tube (10) for canvas is considered the front, Fig. 7 shows a view of the rear of the cover part (100) with the corner part bent.
[0059] Looking at the vicinity of each vertex of the central part (110) of Fig. 7, it can be confirmed that the 2-1 corner part (112-1) and the 2-2 corner part (112-2) are located in the space between the 1-1 corner part (111-1) and the 1-2 corner part (111-2). This is because the location of the groove is biased to one side, and this will be examined below.
[0060] Looking at FIG. 3, it can be confirmed that the center of the groove (circular shape) between the 1-1 corner part (111-1) and the 2-2 corner part (112-2) is positioned toward the 1-1 corner part (111-1), and the area of the circular groove exists across the 1-1 corner part (111-1) and the center part (110).
[0061] In addition, looking at FIG. 4, it can be confirmed that the starting point of the groove (round shape) between the 1-1 corner part (111-1) and the 2-2 corner part (112-2) is located toward the 1-1 corner part (111-1), and the area of the round-shaped groove exists in the 1-1 corner part (111-1).
[0062] In FIGS. 3 and 4, only the groove between the 1-1 corner part (111-1) and the 2-2 corner part (112-2) is shown in detail, but the other three grooves may also be positioned toward the 1-1 corner part (111-1) or the 1-2 corner part (111-2).
[0063] Specifically, the groove existing between the first-first corner part (111-1) and the second-first corner part (112-1) and the groove existing between the first-first corner part (111-1) and the second-second corner part (112-2) may be positioned toward the first-first corner part (111-1).
[0064] Additionally, the groove existing between the first-second corner part (111-2) and the second-first corner part (112-1) and the groove existing between the first-second corner part (111-2) and the second-second corner part (112-2) may be positioned toward the first-second corner part (111-2).
[0065] That is, with respect to the central part (110), the two upper grooves may be positioned to be biased toward the first-first corner part (111-1), and the two lower grooves may be positioned to be biased toward the first-second corner part (111-2). The grooves (circular or round) may be positioned to be biased toward the corner part with the longer length among the adjacent corner parts.
[0066] As above, in a state where the groove is tilted to one side, the transparent tube frame (10) for canvas of the present invention can first bend the shorter 2-1 corner part (112-1) and 2-2 corner part (112-2) to near the beginning of the groove, and then bend the longer 1-1 corner part (111-1) and 1-2 corner part (111-2).
[0067] As a result of bending through the above process, when looking at the back of the cover part (100), it can be confirmed that the upper and lower ends of the 2-1 corner part (112-1) and the 2-2 corner part (112-2) are covered by the 1-1 corner part (111-1) and the 1-2 corner part (111-2). This is to prevent the formation of a boundary line that occurs when bending at both ends of the horizontal length of the cover part (100), since the work (300) is usually horizontal (longer horizontally than vertically).
[0068] Although the position of the home has been described above as being biased toward the 1-1st corner part (111-1) (the home on the top) or the 1-2nd corner part (111-2) (the home on the bottom), in some cases, it may not be biased toward either part but may be positioned in the center or closer to the central part (110). In other words, the position of the home can be freely changed.
[0069] Meanwhile, the transparent tube (10) for canvas of the present invention includes a panel (200) that supports the work (300) in addition to the cover (100). The panel (200) will be examined together with FIGS. 8 and 9.
[0070] FIG. 8 is a drawing showing the connection relationship between a panel portion and a work according to one embodiment of the present invention.
[0071] Figure 8 (a) shows the front of the panel part (200), Figure 8 (b) shows the back of the work (300) (for reference, the front is the direction in which the work is viewed), and Figure 8 (c) is a drawing showing the state in which the panel part (200) and the work (300) are combined, viewed from the front.
[0072] As with the cover part (100) described above, the panel part (200) can also have its corner parts bent to one side (towards the rear) based on the center part. In this case, since the thickness of the panel part (200) is longer than the thickness of the cover part (100), it cannot be bent through simple heat treatment, but can be bent after carving a V-shaped angle along a portion (5 mm deep) along the boundary line.
[0073] In addition, the area of the panel (200) may be larger than the area of the work (300). When positioning the work (300) on the panel (200), the position of the work (300) may be biased to one side rather than the center of the panel (200). To prevent this, the position of the work (300) on the panel (200) may be set, and a plurality of piece holes (210) (e.g., 4) may be created. The position of the piece hole (210) may vary depending on the standardized size of the work (300), and the work (300) may also have a piece hole (310) on the back.
[0074] Next, the corner of the work (300) is positioned at a predetermined position (piece hole) of the panel part (200), and pieces are inserted into the piece holes (210) of the panel part (200) and the piece holes (310) of the work (300) from the rear direction, thereby fixing the panel part (200) and the work (300).
[0075] For reference, the work (300) is a form in which paper, cloth, etc. are fixed on plywood (wood), and the front side has a flat structure, but the back side may have a structure in which the four corners are thicker than the center. Of course, this does not limit the work (300) to be composed of other materials.
[0076] There are piece holes (310) at the four corners, and the piece holes (310) do not penetrate the front of the work (300). Therefore, even if the pieces are combined, the work (300) viewed from the front will not display pieces, piece holes, etc. (Fig. 8 (c)).
[0077] FIG. 9 is a drawing showing a state in which a cover part and a panel part are combined according to one embodiment of the present invention.
[0078] The panel part (200) is combined in a form in which it is wrapped by the cover part (100), and at this time, the cover part (100) and the panel part (200) can be fixed through screw connection.
[0079] Specifically, a plurality of cover screw holes (120) are present on the edge of the cover portion (100), and a plurality of panel screw holes (220) are present on the edge of the panel portion (200). The cover screw holes (120) and the panel screw holes (220) may be present in the same number. Here, the number of screw holes (120, 220) may increase as the sizes of the cover portion (100) and the panel portion (200) increase.
[0080] When the cover part (100) and the panel part (200) overlap, the cover part screw hole (120) and the panel part screw hole (220) can also overlap, and a screw (400) can be inserted through the cover part screw hole (120) and into the panel part screw hole (220) to fix the cover part (100) and the panel part (200).
[0081] Referring to Fig. 9, the lower portion of the screw (400) has a straight column shape, while the head portion has a slanted shape (tapered shape). In addition, the panel screw hole (220) has a column shape, while the cover screw hole (120) has a slanted shape (tapered shape).
[0082] Accordingly, when the screw (400) is combined, the lower part of the screw (400) can be inserted into the panel screw hole (220), and the head part of the screw (400) can be inserted into the cover screw hole (120).
[0083] In particular, the head of the screw (400) and the screw hole (120) of the cover part are inserted in an inclined shape to match, and the head of the screw (400) can form a flat structure with the cover part (100). Since the screw (400) and the like do not protrude in appearance, an aesthetic effect can also be provided.
[0084] Although the present invention has been described above with specific details such as specific components and limited examples and drawings, these are provided only to help a more general understanding of the present invention, and the present invention is not limited to the examples, and those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations from this description.
[0085] Therefore, the idea of the present invention should not be limited to the described embodiments, and all things that are modified equally or equivalently to the following claims as well as the claims are considered to fall within the scope of the idea of the present invention.
