Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of picture frame devices for showing drawing paper such as picture, poster or photograph, in particular to a kind of picture frame device, and the elastic positioning member used by the picture frame device. BACKGROUND

[0002] The existing picture frame device is generally used to clamp a drawing paper (such as picture, photograph, poster, etc.) by a front plate and a back plate, and four locking members are used to lock the four corners of the front plate and the back plate. However, this method cannot firmly clamp the drawing paper, and the drawing paper cannot be flat and conform to the front plate. A patent with the patent publication number M557205 in Taiwan, China provides a picture frame device that can firmly clamp the drawing paper. The picture frame device mainly includes a frame body and a pressing unit. The frame body is formed by bending a transparent plastic plate to form a front plate for contacting and showing the front of the drawing paper, two connecting plates extending backward from the upper and lower edges of the front plate, and two extension plates extending downward and upward from the connecting plates. The pressing unit is arranged on the extension plates to directly or indirectly tightly press the drawing paper against the front plate through a back plate. However, the picture frame device provided by the aforementioned patent has the disadvantage of large thickness due to the need to arrange the pressing unit, which is not aesthetic when hung on the wall.

[0003] Another existing picture frame device is similar to the picture frame device provided by the aforementioned patent. The frame body does not have the connecting plates as described above and has a smaller thickness. The picture frame device replaces the pressing unit of the aforementioned picture frame device with a combination of a bolt, a nut, and a pressing member. The bolt is arranged in the extension plate of the frame body, and the nut and the pressing member are located between the extension plate and the back plate. The nut is screwed and fixed to the bolt so that the bolt tightly presses the back plate and the drawing paper against the front plate through the pressing member. However, the thickness of the frame body of this picture frame device is small, which makes the distance between the extension plate and the back plate small, making it difficult for the user to rotate the nut, and thus the picture frame device is not convenient to disassemble and replace the drawing paper.

[0004] Another patent with the patent publication number 202436136 in Taiwan, China provides another picture frame device. The picture frame device adopts a frame body with a small thickness as described above. The picture frame device uses a fixed unit composed of an elastically bent pressing plate and a hook-and-loop fastener assembly to detachably fix the drawing paper. Although this fixed unit is more convenient to use than the combination of the bolt, the nut, and the pressing member described above, it still requires considerable skill in actual use. The user must apply force to deform the pressing plate elastically and detach or bond the hook-and-loop fastener assembly. Therefore, the picture frame device still has the problem of inconvenience for the user, and needs to be improved. SUMMARY

[0005] In view of the above problems, the main purpose of the utility model is to provide an elastic positioning member of a picture frame device and a picture frame device with the elastic positioning member, which is easy to use and can conveniently replace the drawing paper.

[0006] To achieve the above object, the elastic positioning member of the picture frame device is used to fix a picture on a frame body. The elastic positioning member comprises a base, a pressing part, and an elastic part connected between the base and the pressing part. The base is annular around an imaginary central axis and has an internal space and an opening communicating with the internal space. The base has a first side and a second side facing opposite directions, the opening is located on the first side of the base, and the elastic part is connected to the second side of the base and annular around the imaginary central axis. The elastic positioning member can be subjected to an external force to make the elastic part elastically deform from an initial state to a folded state, and can be subjected to another external force to make the elastic part return to the initial state from the folded state. When the elastic part is in the initial state, the elastic part extends from the second side of the base in a direction away from the base, so that the pressing part is located at a pressing position away from the base, for directly or indirectly pressing the picture. When the elastic part elastically deforms from the initial state to the folded state, the elastic part is folded towards the internal space of the base, so that the pressing part moves from the pressing position to a non-pressing position in the internal space relative to the base along the imaginary central axis.

[0007] To achieve the above object, the elastic positioning member of the picture frame device is used to fix a picture on a frame body. The elastic positioning member comprises a base, a pressing part, and an elastic part connected between the base and the pressing part. The base is annular around an imaginary central axis and has an internal space and an opening communicating with the internal space. The base has a first side and a second side facing opposite directions, the opening is located on the first side of the base, and the elastic part is connected to the second side of the base and annular around the imaginary central axis. The elastic positioning member can be subjected to an external force to make the elastic part elastically deform from an initial state to a folded state, and can be subjected to another external force to make the elastic part return to the initial state from the folded state. When the elastic part is in the initial state, the elastic part extends from the second side of the base in a direction away from the base, so that the pressing part is located at a pressing position away from the base, for directly or indirectly pressing the picture. When the elastic part elastically deforms from the initial state to the folded state, the elastic part is folded towards the internal space of the base, so that the pressing part moves from the pressing position to a non-pressing position in the internal space relative to the base along the imaginary central axis.

[0008] Therefore, when the drawing is arranged on the back of the front plate and the elastic part of the elastic positioning member is in the initial state, the drawing is directly or indirectly pressed by the pressing part of the elastic positioning member on the back of the front plate, i.e. the pressing part of the elastic positioning member can directly press the drawing, or a back plate can be further arranged so that the pressing part of the elastic positioning member indirectly presses the drawing through the back plate. The elastic positioning member of the utility model can produce a good positioning effect on the drawing. As long as a proper number of elastic positioning members are arranged according to the size of the drawing, the drawing can be tightly and flatly fixed to the front plate. When the drawing needs to be removed, the user can exert force on the elastic positioning member through simple actions, such as pressing the base part of the elastic positioning member or the extension plate of the frame body, so that the elastic part of the elastic positioning member is elastically deformed into the folded state, i.e. the pressing part of the elastic positioning member is moved to the non-pressing position, so that the pressing effect of the elastic positioning member on the drawing is released. At this time, the user can easily take out the drawing through the predetermined distance between the elastic positioning member and the front plate, and can replace other drawings. When the drawing needs to be fixed again, the user can exert force on the elastic positioning member through simple actions, such as pressing the pressing part through the opening of the base part of the elastic positioning member, so that the elastic part of the elastic positioning member returns to the initial state, and the pressing part of the elastic positioning member is moved to the pressing position to press the drawing on the front plate. The frame device has a very simple structure, a small number of components and is easy to disassemble and assemble, and the use is very easy, so the drawing replacement can be conveniently performed.

[0009] Preferably, the elastic part of the elastic positioning member comprises a radial extension section and a longitudinal extension section. When the elastic part is in the initial state, the radial extension section extends from the second side of the base part towards the imaginary central axis, and the longitudinal extension section extends from the radial extension section in a direction away from the base part. Therefore, the elastic part is more easily elastically deformed into the folded state, and can be stably maintained in the folded state without automatically returning to the initial state, and the user can easily operate the elastic positioning member. The user can only slightly exert force on the elastic positioning member through simple actions to convert the elastic part between the initial state and the folded state.

[0010] More preferably, when the elastic part is in the initial state, the longitudinal extension section of the elastic part is tapered and extends from the radial extension section in a direction away from the base part in a manner of gradually approaching the imaginary central axis. Therefore, the elastic part is more easily folded towards the internal space of the base part, and can be more stably maintained in the folded state without automatically returning to the initial state, and the user can easily operate the elastic positioning member. The user can only slightly exert force on the elastic positioning member through simple actions to convert the elastic part between the initial state and the folded state.

[0011] Preferably, the pressing portion of the elastic positioning member has an inner surface and an outer surface facing in opposite directions, the inner surface of the pressing portion faces the interior space and the opening of the base, and the elastic positioning member further comprises an operation protrusion extending from the inner surface of the pressing portion toward the opening, for a user to press the operation protrusion to move the pressing portion from the non-pressing position to the pressing position. Thus, the user can easily press the operation protrusion through the opening of the base of the elastic positioning member to move the pressing portion from the non-pressing position to the pressing position.

[0012] More preferably, when the pressing portion is in the non-pressing position, the operation protrusion is located in the opening of the base, i.e. the operation protrusion can just be located in the opening or even protrude out of the opening, so that the user can more easily press the operation protrusion to move the pressing portion from the non-pressing position to the pressing position.

[0013] Preferably, the pressing portion of the elastic positioning member comprises a main body having an inner surface and an outer surface facing in opposite directions, and a pressing protrusion or a plurality of pressing protrusions arranged in an interval, the inner surface of the main body of the pressing portion faces the interior space and the opening of the base, and the pressing protrusion or the plurality of pressing protrusions protrude from the outer surface of the main body. Thus, when the pressing portion of the elastic positioning member is in the pressing position, the drawing is directly or indirectly pressed against the back of the front plate by the pressing protrusion or the plurality of pressing protrusions of the pressing portion, which can produce a better pressing effect. Moreover, in the case of a back plate, the drawing is arranged between the front plate and the back plate, and the back plate can be provided with perforations for the pressing protrusion or the plurality of pressing protrusions of the elastic positioning member to be embedded in the perforations of the back plate, so that the pressing portion of the elastic positioning member can simultaneously press against the back plate by the main body and press against the drawing by the pressing protrusion or the plurality of pressing protrusions embedded in the perforations of the back plate, thereby producing a better pressing effect and preventing the back plate from sliding.

[0014] More preferably, the hardness of the pressing protrusion or the plurality of pressing protrusions is less than that of the main body of the pressing portion. Thus, the main body can be made of a material with a greater hardness to improve the structural strength and the pressing effect of the elastic positioning member, and the pressing protrusion or the plurality of pressing protrusions can be made of a material with a smaller hardness to avoid damaging the drawing when directly pressing against the drawing.

[0015] Preferably, the extension plate of the frame has at least one mounting hole penetrating through the inner surface and the outer surface thereof, and the base of the elastic positioning member has an outer circumferential surface and a groove located on the outer circumferential surface, and the base of the elastic positioning member is arranged through the mounting hole of the extension plate so that the extension plate is embedded in the groove of the base. Thus, the base of the elastic positioning member can be easily mounted to the mounting hole of the frame, and the base of the elastic positioning member is fixed to the extension plate in a stable manner.

[0016] Preferably, the base of the elastic positioning member has a tapered guide surface between the groove and the elastic portion. Thus, when the elastic positioning member is installed, the pressing portion is inserted into the mounting hole, and the base is smoothly installed into the mounting hole of the frame body by the guidance of the tapered guide surface.

[0017] Preferably, the frame body includes two extension plates integrally connected to the two edges of the front plate in opposite directions, and each extension plate is provided with at least one elastic positioning member. Thus, the elastic positioning members are provided on the two extension plates only a short distance from the two edges of the front plate. By providing the elastic positioning members on the two extension plates, the positions of the elastic positioning members are adjacent to the two edges of the front plate, so that the elastic positioning members press against the drawing sheet adjacent to the opposite edges of the drawing sheet. By arranging an appropriate number of elastic positioning members on the two extension plates according to the size of the drawing sheet, the drawing sheet can be fixed firmly and flatly on the front plate. Moreover, the edges of the two extension plates are flexible, and the positions of the elastic positioning members are adjacent to the edges of the extension plates, so that the user can easily press the elastic positioning members through the extension plates.

[0018] Preferably, when the pressing portion of the elastic positioning member is in the non-pressing position, the distance between the back surface of the front plate of the frame body and the inner surface of the extension plate is defined as a first distance; when the pressing portion of the elastic positioning member is in the pressing position, the distance between the pressing surface of the pressing portion and the inner surface of the extension plate of the frame body along the imaginary central axis is defined as a second distance; the second distance is greater than the first distance. Thus, when the pressing portion of the elastic positioning member is in the pressing position, the pressing surface of the pressing portion does not just contact the drawing sheet, but pushes the drawing sheet tightly and even slightly elastically deforms the extension plate of the frame body to be away from the front plate, so that the elastic positioning member can have a good fixing effect on the drawing sheet.

[0019] Preferably, when the pressing portion of the elastic positioning member is in the non-pressing position, the back surface of the front plate of the frame body and the inner surface of the extension plate are parallel to each other; when the pressing portion of the elastic positioning member moves from the non-pressing position to the pressing position, the extension plate of the frame body is forced to elastically deform so that the inner surface of the extension plate is inclined relative to the back surface of the front plate away from the front plate. Thus, when the pressing portion of the elastic positioning member is in the pressing position, the pressing surface of the pressing portion does not just contact the drawing sheet, but pushes the drawing sheet tightly and further slightly elastically deforms the extension plate of the frame body to be away from the front plate, so that the elastic positioning member can have a good fixing effect on the drawing sheet.

[0020] Preferably, the picture frame device further comprises a back plate having a front surface and a rear surface, the back plate is arranged on the back surface of the front plate with the front surface thereof facing the front plate, for allowing the picture to be arranged between the back surface of the front plate and the front surface of the back plate; when the pressing portion of the elastic positioning member is located at the pressing position, the pressing portion presses against the rear surface of the back plate. Thus, the pressing portion of the elastic positioning member presses against the picture through the back plate, and the back plate can make the picture more flat and conform to the front plate, and can protect the picture from being damaged.

[0021] More preferably, the back plate has at least one through hole penetrating through the front surface and the rear surface, when the pressing portion of the elastic positioning member is located at the pressing position, the pressing portion is partially embedded in the through hole of the back plate and presses against the picture. Thus, when the pressing portion of the elastic positioning member is located at the pressing position, the pressing portion of the elastic positioning member can be partially pressed against the back plate, and at the same time, is partially embedded in the through hole of the back plate and presses against the picture, thereby generating a better pressing effect and preventing the back plate from sliding.

[0033] The applicant first states herein that, in the embodiments to be introduced below and the accompanying drawings, identical reference numerals represent identical or similar components or structural features. It is noted that the components and structures in the drawings are drawn for the convenience of illustration and are not drawn according to the actual proportions and quantities, and if possible, the features of different embodiments can be applied interactively. Secondly, when referring to a component disposed on another component, it means that the former component is directly disposed on the latter component, or the former component is indirectly disposed on the latter component, that is, one or more other components are disposed between the two components. When referring to a component "directly" disposed on another component, it means that no other components are disposed between the two components.

[0034] Please refer to Figure 1 and Figure 2 The picture frame device 11 according to the first preferred embodiment of the present application comprises a frame body 20 and six elastic positioning members 30.

[0035] The frame 20 comprises a front plate 21 having a front face 211 and a back face 212, and two extension plates 22 integrally connected to two opposite edges (i.e. upper edge 213 and lower edge 214) of the front plate 21 respectively, and extending from the upper and lower edges 213, 214 of the front plate 21 to the back (i.e. the direction facing the back face 212). Each extension plate 22 comprises a connecting portion 23 integrally connected to the front plate 21 and extending obliquely backward, and an extending portion 24 integrally connected to the connecting portion 23, the extending portion 24 having an inner surface 241 facing the back face 212 of the front plate 21, an outer surface 242, and a plurality of mounting holes 243 penetrating the inner surface 241 and the outer surface 242. By virtue of the bending structure of the frame 20, a receiving space 25 is formed between each extension plate 22 and the front plate 21, in other words, the frame 20 of the present embodiment has two receiving spaces 25 adjacent to the upper and lower edges 213, 214 of the front plate 21 respectively.

[0036] In the present embodiment, the frame 20 is integrally formed, and in practice, the frame 20 can be formed by bending a transparent plastic flat plate, so that the frame 20 has a transparent front plate 21 and transparent extension plates 22, which can be made of (but not limited to) acrylic, polyethylene terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), or polycarbonate (PC). However, the frame 20 of the present utility model is not limited to the above-mentioned embodiment, for example, the front plate 21 and the extension plates 22 can be two independent components connected to each other by locking, clamping, fixing, or other means, and secondly, the extension plates 22 can also be opaque.

[0037] The frame 20 is used for inserting a drawing 40 into the receiving space 25 between the front plate 21 and the two extension plates 22, and directly placing the drawing 40 on the back face 212 of the front plate 21 with the surface having patterns of the drawing 40 facing the front plate 21, so that the patterns of the drawing 40 are displayed through the transparent front plate 21. However, the drawing 40 is not fixed when it is placed on the back face 212 of the front plate 21, and needs to be fixed by the elastic positioning member 30, which will be described in detail below.

[0038] It is to be noted that the present embodiment provides three elastic positioning members 30 on each extension plate 22, however, the number of elastic positioning members 30 provided on each extension plate 22 is not limited, and the elastic positioning members 30 can be provided on one or more appropriate positions of each extension plate 22 according to the size of the frame 20 (or the size of the drawing 40) and the size of the elastic positioning members 30, as long as the drawing 40 can be fixed on the back surface 212 of the front plate 21 in a conformable manner. In addition, the design of the extension plates 22 of the frame 20 is not limited to that provided in the present embodiment, and the number of the extension plates 22 is not limited to two, as long as the extension plates 22 of the frame 20 can provide appropriate number of elastic positioning members 30 arranged on appropriate positions to fix the drawing 40 on the back surface 212 of the front plate 21 in a conformable manner.

[0039] Referring to Figure 3 and Figure 4 , the elastic positioning member 30 is integrally formed by a soft material, which can be molded by a mold or injection molding, and the soft material is, for example, thermoplastic polyurethane (TPU). The elastic positioning member 30 includes, in sequence, a base portion 31, an elastic portion 33, and a pressing portion 35.

[0040] The base portion 31 is annular around an imaginary central axis A and has an inner space 311, and an opening 312 communicating with the inner space 311. The base portion 31 has a first side 313 and a second side 314 facing opposite directions, and the opening 312 is located on the first side 313 of the base portion 31. In addition, the base portion 31 has an outer peripheral surface 315, a groove 316 recessed from the outer peripheral surface 315 and annular around the imaginary central axis A, and a tapered guide surface 317 located between the groove 316 and the elastic portion 33 and gradually reducing in diameter from the groove 316 to the elastic portion 33.

[0041] The elastic portion 33 is integrally connected to the second side 314 of the base portion 31 and is also annular around the imaginary central axis A. The elastic portion 33 includes a radial extension section 331 integrally connected to the base portion 31, and a longitudinal extension section 332 integrally connected to the radial extension section 331. Figures 2 to 4 and Figure 6The elastic part 33 shown in the middle is in an initial state S1, i.e. the state of the elastic positioning member 30 when it is manufactured, in which state, the radial extension segment 331 of the elastic part 33 extends from the second side 314 of the base 31 towards the imaginary central axis A, the longitudinal extension segment 332 extends from the radial extension segment 331 in a direction away from the base 31, and the longitudinal extension segment 332 in this embodiment is conical, extending from the radial extension segment 331 in a direction away from the base 31 in a manner gradually approaching the imaginary central axis A. It should be noted that the structural feature of the present application that "the radial extension segment 331 extends from the second side 314 of the base 31 towards the imaginary central axis A" actually includes the case where the radial extension segment 331 extends entirely horizontally towards the imaginary central axis A, and another state where the radial extension segment 331 extends in a direction away from the base 31 (i.e. the downward direction shown in the figure) while gradually approaching the imaginary central axis A, in which another state, the radial extension segment 331 is also conical, only the tapering angle of the radial extension segment 331 and the longitudinal extension segment 332 is different. Figure 4 The elastic part 33 shown in the middle is in an initial state S1, i.e. the state of the elastic positioning member 30 when it is manufactured, in which state, the radial extension segment 331 of the elastic part 33 extends from the second side 314 of the base 31 towards the imaginary central axis A, the longitudinal extension segment 332 extends from the radial extension segment 331 in a direction away from the base 31, and the longitudinal extension segment 332 in this embodiment is conical, extending from the radial extension segment 331 in a direction away from the base 31 in a manner gradually approaching the imaginary central axis A. It should be noted that the structural feature of the present application that "the radial extension segment 331 extends from the second side 314 of the base 31 towards the imaginary central axis A" actually includes the case where the radial extension segment 331 extends entirely horizontally towards the imaginary central axis A, and another state where the radial extension segment 331 extends in a direction away from the base 31 (i.e. the downward direction shown in the figure) while gradually approaching the imaginary central axis A, in which another state, the radial extension segment 331 is also conical, only the tapering angle of the radial extension segment 331 and the longitudinal extension segment 332 is different.

[0042] The pressing part 35 in this embodiment includes a main body 351 which is generally in the shape of a circular plate, and a pressing protrusion 352 located in the middle of the main body 351, the main body 351 integrally connects and encloses the end of the longitudinal extension segment 332 of the elastic part 33, the main body 351 has an inner surface 353 and an outer surface 354 which face in opposite directions, the inner surface 353 faces the inner space 311 and the opening 312 of the base 31, and the pressing protrusion 352 protrudes out from the outer surface 354. In addition, the elastic positioning member 30 in this embodiment also includes an operation protrusion 36 which extends from the inner surface 353 of the pressing part 35 towards the opening 312.

[0043] When installed, the user can first pass the pressing part 35 of the elastic positioning member 30 into the mounting hole 243 and apply force to the base 31, guided by the tapering guide surface 317, and the base 31 of the elastic positioning member 30 is slightly elastic due to its material and shape, so the base 31 can be forcedly inserted into the mounting hole 243 of the extension plate 22 of the frame 20, and the blocks around the mounting hole 243 of the extension plate 22 are embedded into the grooves 316 of the base 31, as shown in Figs. 2 and 3, so that the base 31 of the elastic positioning member 30 can be fixed to the extension plate 22 in a relatively stable manner. Figure 5 Figure 6 In addition, the elastic part 33 of the elastic positioning member 30 is good in elasticity due to its material and shape, so the elastic positioning member 30 can be subjected to an external force to elastically deform the elastic part 33 from the initial state S1 to a folded state S2, and can be subjected to another external force to restore the elastic part 33 from the folded state S2 to the initial state S1, which will be described in detail below.

[0044] As shown in Figs. 2 and 3, the elastic positioning member 30 is installed in the mounting hole 243 of the extension plate 22 of the frame 20, and the base 31 of the elastic positioning member 30 is fixed to the extension plate 22 in a relatively stable manner. Figure 6 ​As shown, when the elastic portion 33 of the elastic positioning member 30 is in the initial state S1, the elastic portion 33 extends from the second side 314 of the base portion 31 toward the front plate 21 of the frame 20, and at this time, the pressing portion 35 of the elastic positioning member 30 is located at a pressing position P1 away from the base portion 31, and a pressing surface 355 of the pressing portion 35 farthest away from the base portion 31 directly presses the drawing paper 40 on the back surface 212 of the front plate 21 of the frame 20, so that a good positioning effect can be achieved on the drawing paper 40. As long as the size of the drawing paper 40 is matched and a proper number of elastic positioning members 30 are arranged, and the elastic portion 33 of each elastic positioning member 30 is in the initial state S1, the drawing paper 40 can be firmly and tightly pressed against the front plate 21 of the frame 20 and be flat and conformable to the front plate 21. Figure 4 As shown, when the elastic portion 33 of the elastic positioning member 30 is in the initial state S1, the elastic portion 33 extends from the second side 314 of the base portion 31 toward the front plate 21 of the frame 20, and at this time, the pressing portion 35 of the elastic positioning member 30 is located at a pressing position P1 away from the base portion 31, and a pressing surface 355 of the pressing portion 35 farthest away from the base portion 31 directly presses the drawing paper 40 on the back surface 212 of the front plate 21 of the frame 20, so that a good positioning effect can be achieved on the drawing paper 40. As long as the size of the drawing paper 40 is matched and a proper number of elastic positioning members 30 are arranged, and the elastic portion 33 of each elastic positioning member 30 is in the initial state S1, the drawing paper 40 can be firmly and tightly pressed against the front plate 21 of the frame 20 and be flat and conformable to the front plate 21.

[0045] When the user wants to release the pressing effect of the elastic positioning member 30 on the drawing paper 40, he / she only needs to press one edge block 244 of the extension plate 22 toward the front plate 21, so that an external force is applied to the elastic positioning member 30 to push the base portion 31 toward the front plate 21, and the pressing portion 35 is pushed toward the base portion 31 by the reaction force from the front plate 21, and the external force forces the elastic portion 33 to fold into a folded state S2 as shown, so that the pressing portion 35 moves relative to the base portion 31 along the imaginary central axis A to a non-pressing position P2 in the internal space 311. Without further external force, the elastic portion 33 will maintain the folded state S2, i.e. the pressing portion 35 will maintain the non-pressing position P2, so that the pressing effect of the elastic positioning member 30 on the drawing paper 40 is released. At this time, the elastic positioning member 30 is separated from the front plate 21 by a predetermined distance D, so that the user can easily take out the drawing paper 40 and replace it with another drawing paper 40. Figure 5

[0046] When the user wants to fix the drawing paper 40 again, he / she can insert a finger into the opening 312 of the elastic positioning member 30 and press the operation block 36, so that the pressing portion 35 is moved from the non-pressing position P2 to the pressing position P1 by applying an external force to the elastic positioning member 30, i.e. the elastic portion 33 is returned from the folded state S2 to the initial state S1. At the same time, the other finger can slightly pull the edge block 244 of the extension plate 22 away from the front plate 21, which helps the elastic portion 33 of the elastic positioning member 30 to return to the initial state S1. As long as the elastic portion 33 of each elastic positioning member 30 is returned to the initial state S1, the drawing paper 40 can be firmly and tightly pressed against the front plate 21 of the frame 20 and be flat and conformable to the front plate 21 again.

[0047] As shown in Figure 5 and Figure 6 ​As shown, the elastic positioning member 30 in this embodiment is designed to allow the frame 20 to undergo slight elastic deformation, thereby improving the fixation effect on the drawing 40. Specifically, when the pressing part 35 of the elastic positioning member 30 is in the non-pressing position P2, the frame 20 is in an unstressed state. At this time, the back surface 212 of the front plate 21 and the inner surface 241 of the extension plate 22 are approximately parallel to each other, and their distance is defined as a first distance d1. When the pressing part 35 of the elastic positioning member 30 is in the pressing position P1, a second distance d2 (equivalent to the distance between the groove 316 and the pressing surface 355) can be defined along the imaginary central axis A between the pressing surface 355 of the pressing part 35 and the inner surface 241 of the extension plate 22 of the frame 20. This second distance d2 is indicated by the following symbol: Figure 4 In this embodiment, the second distance d2 is set to be greater than the first distance d1. That is, when the frame 20 is not under stress, the width of its accommodating space 25 (i.e., the first distance d1) is insufficient to accommodate the elastic positioning member 30 when it is not deformed under stress. However, the frame 20 is slightly elastic due to its material and structure, and can be pushed back by the elastic positioning member 30, causing the extension plate 22 to be slightly pushed backward. In other words, if... Figure 5 and Figure 6 As shown, when the pressing part 35 of the elastic positioning member 30 moves from the non-pressing position P2 to the pressing position P1, it forces the extension plate 22 of the frame 20 to elastically deform, causing its extension 24 to tilt relative to the front plate 21 away from it. This results in a slight increase in the distance between the inner surface 241 of the extension 24 and the back surface 212 of the front plate 21, making them no longer parallel. In this way, Figure 6 The elastic positioning element 30 shown in the figure will be pressed more tightly against the drawing 40 by the elastic restoring force of the extension plate 22 of the frame 20. This elastic positioning element 30 can produce a better fixing effect on the drawing 40.

[0048] Furthermore, in this embodiment, the pressing portion 35 of the elastic positioning member 30 includes a main body 351 and a pressing protrusion 352. Therefore, the pressing portion 35 presses against the drawing 40 with its pressing protrusion 352, that is, the pressing surface 355 of the pressing portion 35 is located at the pressing protrusion 352. This design can produce a better pressing effect. However, the elastic positioning member 30 provided by this utility model is not limited to this. For example, such as Figure 7As shown, the pressing part 35 includes a main body 351 and a plurality of pressing protrusions 357. These pressing protrusions 357 are spaced apart from each other and extend outward from the main body 351 in a matrix shape. By pressing the drawing 40 with these relatively small and numerous pressing protrusions 357, a better pressing effect can be achieved. Secondly, the elastic positioning member 30 can also be made of composite material, so that the hardness of the pressing protrusions 352 or pressing protrusions 357 is less than the hardness of the main body 351. In this way, the structural strength and pressing effect of the elastic positioning member 30 can be improved by the harder main body 351, and the softer pressing protrusions 352 or pressing protrusions 357 can produce a buffering effect when directly pressing against the drawing 40, thereby avoiding damage to the drawing 40. However, the pressing part 35 of the elastic positioning member 30 may also not have pressing protrusions 352 or pressing protrusions 357. In this case, the pressing surface 355 of the pressing part 35 is the outer surface 354 of the main body 351.

[0049] Furthermore, the elastic positioning member 30 in this embodiment includes an operating protrusion 36. When the pressing part 35 is in the non-pressing position P2, the operating protrusion 36 is located at the opening 312 of the base 31, making it convenient for the user to press the operating protrusion 36 and thus push the pressing part 35. However, the elastic positioning member 30 in this invention may not have an operating protrusion 36, allowing the user to insert their finger into the internal space 311 of the base 31 and directly press the inner surface 353 of the pressing part 35. When an operating protrusion 36 is present, its shape can also be configured as follows: Figures 7 to 9 The structure shown includes a body 361 integrally connected to the inner surface 353 of the pressing part 35, and a head 362 integrally connected to the body 361. Figure 7 As shown, the head 362 of the operating protrusion 36 may have a concave arc surface 363, allowing the user's finger to press against the concave arc surface 363, thereby making it easier to push the operating protrusion 36. Figure 7 and Figure 8 As shown, the body 361 of the operating protrusion 36 can be set to be relatively long, so that the head 362 is already located in the opening 312 when the pressing part 35 is in the pressing position P1. In this way, when the pressing part 35 is in the non-pressing position P2, the head 362 of the operating protrusion 36 will protrude outside the opening 312, making it convenient for the user to press. Or, as Figure 9 As shown, the body 361 of the operating protrusion 36 can be set to be shorter, so that the head 362 is accommodated in the internal space 311 of the base 31 when the pressing part 35 is in the pressing position P1.

[0050] Please see Figure 10 and Figure 11 The frame device 12 provided in the second preferred embodiment of this utility model is similar to the aforementioned frame device 11, except that the frame device 12 also includes a back plate 50.

[0051] The back plate 50 is flat, has a front surface 51, a back surface 52, and a plurality of through holes 53 penetrating the front surface 51 and the back surface 52. The back plate 50 covers the drawing 40 with the front surface 51 thereof facing the back surface 212 of the front plate 21 and the drawing 40, i.e. the back plate 50 is arranged on the back surface 212 of the front plate 21 with the drawing 40 between the back surface 212 of the front plate 21 and the front surface 51 of the back plate 50.

[0052] When the pressing portion 35 of the elastic positioning member 30 is in the pressing position P1, the main body 351 of the pressing portion 35 presses against the back surface 52 of the back plate 50, and thus indirectly presses the drawing 40 against the back surface 212 of the front plate 21 through the back plate 50, and the pressing block 352 of the pressing portion 35 is embedded in the through hole 53 of the back plate 50 and directly presses against the drawing 40. In this way, the elastic positioning member 30 and the back plate 50 can together generate a pressing effect on the drawing 40, thus generating a better pressing effect, and the back plate 50 can make the drawing 40 more flat and conform to the front plate 21, and can protect the drawing 40 from damage.

[0053] However, in the case where the frame device of the present application includes the back plate 50, the back plate 50 can also not be provided with the through holes 53, i.e. the pressing portion 35 of the elastic positioning member 30 is not limited to being partially embedded in the back plate 50 to directly press against the drawing 40, but can only press against the back plate 50 to indirectly press against the drawing 40 through the back plate 50. Only in the embodiment of the present application, the pressing portion 35 is partially embedded in the through hole 53 of the back plate 50 and directly presses against the drawing 40, which can generate a better fixing effect on the drawing 40 and prevent the back plate 50 from sliding.

[0054] In summary, the frame device 11, 12 of the present application has a very simple structure, a small number of components, and is easy to disassemble and assemble. The elastic positioning member 30 is easy to use, and the drawing can be easily replaced. From the foregoing, it can be seen that the key point of the present application is to use the elastic positioning member 30 to fix the drawing 40 to the frame 20, and the way in which the frame device 11, 12 is arranged on the display wall is not the key point of the present application. Even the structural features of the present application are not limited to being applied to the frame device arranged on the display wall, and therefore this part is not shown in the drawings. For example, the frame device 11, 12 of the present application can be optionally combined with an adhesive assembly (not shown in the drawings), such as a Velcro assembly, to fix the extension plate 22 of the frame 20 to the display wall. Alternatively, the frame device 11, 12 can be optionally combined with a fixing member (not shown in the drawings) such as a hanging rope, a hook, a nail, etc. to be hung or fixed on the display wall. For example, Figure 1 and Figure 10As shown, the mounting holes 243 of the extension plate 22 of the frame body 20 can only use a part to set the elastic positioning members 30, and the mounting holes 243 without setting the elastic positioning members 30 can be used to set the aforementioned fixing members to hang the frame devices 11 and 12 on the display wall.

[0055] Finally, it must be noted again that the components described in the foregoing embodiments are only for illustration and are not intended to limit the scope of the present application, and other equivalent components or changes should also be covered by the scope of the present application.
