Description

[Technical Field]

[0001] The present invention relates to a resin calendar stand that can be easily molded by injecting resin into a mold, and can be easily used as a calendar stand by rotating the leg frame relative to the main body. [Background technology]

[0002] Novelty calendars displaying company or organization names are produced by numerous companies and organizations, and are often distributed for advertising purposes along with easy-to-assemble calendar stands or cases. These calendar stands and cases are typically made by molding plastic resin, for example, and allow for easy display of calendars and other cards such as postcards.

[0003] Conventional calendar cases, as shown in Figures 6(a) and (b), for example, are calendar cases 700 in which the main body 710 and lid 730 function as a case when closed, and function as a calendar stand when the lid 730 is rotated more than 270 degrees relative to the main body 710 and opened. In the calendar case 700, the left and right upper and lower frame pieces, which are erected on the periphery of the lid 730, fit into the left and right side edge frame pieces 720L, 720R and lower edge frame piece 720D, which are erected on the left and right side edges and lower edge of the main body 710, to form a closed state (Figure 6(a)). When the lid 730 is rotated relative to the main body 710 to form an open state (Figure 6(b)), the lower end of the calendar 100 can be brought into contact with the lower edge frame piece 720D of the main body 710, allowing the calendar 100 to be displayed. Furthermore, the lower edge stopper 722, which is erected from the front end of the lower edge frame piece 720D, blocks the front of the lower edge of the inserted calendar 100, thereby preventing the calendar 100 from falling out in front of the main body 710. However, the calendar case 700 requires sufficient mounting surface space for the lid 730, as shown in Figure 6(b).

[0004] On the one hand, the calendar stand according to Patent Document 1 is mainly used as a calendar holder, which can freely store a predetermined number of calendar sheets, for example, monthly calendar sheets, in a desktop or wall-mounted manner. Also, when not in use, etc., the calendar sheets are supported by stopper pieces provided at the opening edge of the case body and can be folded so that the whole presents a flat shape in the stored state. Such a calendar stand generally does not require a space for placing a lid body like the above calendar case 700 shown in FIG. 6(b).

[0005] For example, as shown in FIGS. 5(a) to (c), a conventional calendar stand 500 as described in Patent Document 1 includes a base plate 502 defined in a rectangular shape by an outer edge portion 510e (upper edge portion 510u, lower edge portion 510d, left and right side edge portions 510l, 510r), and a frame piece 520 (lower edge frame piece 520D and left and right side edge frame pieces 520L, 520R) protruding from the outer edge portion 510e. The main body 510 (see FIG. 5(a)) is composed of a left and right arm 532 (532L, 532R) pivotally supported on the left and right side edge frame pieces 520L, ......

[0006] The conventional calendar stand 500 according to FIG. 5 can open the leg frame body 530 by rotating the left and right arms 532 from the main body 510. Then, the main body 510 can be supported by the opened leg frame body 530 and can be set in a standing posture obliquely upward from the placement surface. Also, similar to the above calendar case 700, a lower edge stopper 522 protrudes parallel to the base plate 502 from the tip of the lower edge frame piece 520D in the direction of the upper edge portion 510u.

[0007] As shown in FIGS. 5 and 6, a conventional calendar stand 500 (or calendar case 700) can display the calendar 100 by inserting the lower end of the calendar 100 inserted from the upper edge portion 510u with the left and right side edge frame pieces 520L and 520R as guides and making it abut against the lower edge frame piece 520D. Then, by closing the front of the lower edge of the calendar 100 into which the lower edge stopper 522 is inserted, it is possible to prevent the calendar 100 from detaching from or falling off the base plate 502.

[0008] However, in the conventional calendar stand 500 with such a configuration, in order to pivotally support the left and right arms 532 of the leg frame body 530 outside the left and right side edge frame pieces 520L and 520R of the main body 510, in the closed leg state where the left and right arms 532 are parallel to the main body 510, these left and right arms 532 protrude outside the left and right side edge frame pieces 520L and 520R, spoiling the aesthetic feeling when the legs are closed, and the leg frame body 530 also gets in the way when storing or packing a large number of calendar stands 500 in a box. Alternatively, the left and right arms 532 can be removed from the main body 510 for storage, but it is inconvenient because the leg frame body 530 is easily lost.

[0009] Furthermore, since the lower edge stopper 522 is provided parallel to the base plate 502 in the direction from the tip of the lower edge frame piece 520D to the upper edge portion 510u, as shown in FIG. 6(b), the front of the lower edge of the calendar 100 is closed. However, for such a novelty calendar 100, the name of the company or organization that wants to be most publicized is often displayed around the lower edge. In the conventional calendar stand 500, the lower edge stopper 522 of the main body 510 hides the display of the important company name and the like, and there is a problem that it cannot be clearly displayed. Also, when the card to be displayed is a postcard or a photograph, etc., the lower edge stopper 522 gets in the way and spoils the composition and aesthetic feeling. This also applies to the above-mentioned calendar case 700.

[0010] On the other hand, the calendar stand described in Patent Document 2 differs from the conventional calendar stand 500, such as that described in Patent Document 1 and Figure 5, in that its legs are stored inside the main body. The calendar stand of Patent Document 2 is primarily used as a desk stand, storing a predetermined number of calendar sheets, for example, for each month, in a replaceable manner. When not in use, the legs, which are formed in a concave shape when viewed from the back, are stored in groove-shaped storage compartments formed on both sides and the bottom of the back of the main body where the calendar sheets are stored. This allows the entire stand to be folded into a flat shape of a predetermined thickness while the calendar sheets are stored inside. However, the problem that the lower edge stopper piece obscures the display of the company name, etc., remains unresolved, and the structure is complex and costly.

[0011] [Patent Document 1] Design Registration No. 1212191 Gazette [Patent Document 2] Design Registration No. 1392042 Gazette [Overview of the project] [Problems that the invention aims to solve]

[0012] Therefore, the present invention provides a resin calendar stand that can clearly display the text and composition on the lower edge of the calendar or card to be inserted, and can neatly store the leg frame in the main body, and can be efficiently produced using a mold by devising the arrangement and configuration of its components. [Means for solving the problem]

[0013] (Calendar stand configuration) The calendar stand according to the present invention includes a base plate whose display surface and back surface are defined in a rectangular shape by an outer edge consisting of an upper edge, a lower edge, and left and right side edges, and a lower edge frame piece projecting from the lower edge and left and right side edge frame pieces projecting from the left and right side edges, extending from the back surface of the base plate toward the display surface in a direction perpendicular to the base plate (hereinafter also referred to as the "positive direction," and the opposite direction also referred to as the "negative direction"), and the calendar can be displayed by using the left and right side edge frame pieces as guides to bring the lower end of the calendar inserted from the upper edge into contact with the lower edge frame piece. The base plate is at a height h from the lower edge frame piece. b At position h b The main base plate is higher up, and the height h b It is cut to a lower leg base plate, and from the lower edge frame piece to a height h S Below the branching point in the vicinity, the left and right side edge frame pieces, each with a front view width d, have a width d in and width d out (d in +d out =d) is cut into left and right inner edge frame pieces and left and right outer edge frame pieces, and the leg frame body, which is formed by the left and right outer edge frame pieces connected to the leg base plate, is pivotally supported via pivot means on the main body which includes left and right upper side edge frame pieces above the branching portion and the left and right inner edge frame pieces that are continuous therebelow them, the lower edge frame piece, and the main body base plate, and the leg frame body which is pivotally supported via pivot means, and the leg frame body which is reversibly rotatable from a closed leg state parallel to the main body to an open leg state separated from the main body, At the branching point of the main body, the left and right outer edge frame pieces, which are rotatably supported on the left and right inner edge frame pieces by the pivot support means, are rotated relative to the main body, causing the leg frame to spread open and support the main body in an upright position.

[0014] (Spindle support means) In the calendar stand according to the present invention, the shaft support means is composed of left and right pins or left and right hole portions provided inside the left and right outer edge frame pieces respectively, and left and right hole portions or left and right pins provided outside the left and right inner edge frame pieces respectively. It is preferable that the left and right pins are inserted into the left and right hole portions to pivotally support the left and right outer edge frame pieces on the left and right inner edge frame pieces.

[0015] (Cutting plane) The calendar stand according to the present invention is the above calendar stand that can be in a standing posture in which the lower end of the leg frame body and the main body are brought into contact with the placement surface by rotating the left and right outer edge frame pieces with respect to the main body, and the main body base plate forms an angle of θ degrees from the placement surface. In the branch portion, while the upper side edge frame piece above this and the inner edge frame piece are continuous, the upper side edge frame piece and the outer edge frame piece are cut by a cutting plane. The cutting plane at the lower end of the upper side edge frame piece is a tapered cutting plane forming an angle of θ degrees in the negative direction, and the cutting plane at the upper end of the outer edge frame piece is a convex cutting plane in which a tapered front cutting plane forming an angle of θ degrees in the negative direction and a rear cutting plane parallel to the negative direction are continuous in the negative direction. It is preferable.

[0016] (Lower corner stopper piece) In the calendar stand according to the present invention, it is preferable that left and right lower corner stopper pieces parallel to the base plate are formed so as to connect the tip portions of the lower edge frame piece and the left and right inner edge frame pieces at the left and right lower corners where the lower edge frame piece of the base plate intersects the left and right inner edge frame pieces respectively.

[0017] (Height of the lower corner stopper piece) The calendar stand according to the present invention has a leg base plate cut at a position having a height h b from the lower edge frame piece, and the leg base plate has a height h a (h a <h b ), and is left and cut as a convex stopper base plate having a front view width narrower than the interval between the left and right lower corner stopper pieces. The leg base plate has a height h bIt is cut at the position, and its lower end is cut into a concave shape that fits with the convex stopper base plate, so that the convex stopper base plate can hold the rear of the lower edge of the calendar that is inserted from its upper edge using the left and right side edge frame pieces of the main body as guides.

[0018] (Convex stopper base plate) The calendar stand according to the present invention has a height of h such that the height of the left and right lower corner stopper pieces from the lower edge frame piece is the height of the leg base plate. b In the closed leg configuration, it is preferable to provide a gap corresponding to the leg base plate at a position opposite to the left and right lower corner stopper pieces.

[0019] (Gap in the base plate) The calendar stand according to the present invention has a height H from the lower edge frame piece to the upper edge, and a height h from the lower edge frame piece. S Below the branching point in the vicinity, the left and right side edge frame pieces, each with a front view width d, have a width d in and width d out (d in +d out In the calendar stand described above, which is cut into left and right inner edge frame pieces and left and right outer edge frame pieces, At a height y (0 ≤ y ≤ H) from the lower edge, the front view width d = d(y) of the left and right side edge frame pieces is tapered, decreasing monotonically as the height y increases, and the width d of the left and right inner edge frame pieces and the left and right outer edge frame pieces in (y) and width d out (y) is d in (y)+d out (y)=d(y), 0≦y≦h S It may be done in a way that satisfies the following conditions. [Effects of the Invention]

[0020] (Calendar stand configuration) The calendar stand according to the present invention has a height h from its lower edge frame piece. SAt the branching point, the left and right side edge frame pieces are cut into left and right inner edge frame pieces and left and right outer edge frame pieces, and the left and right outer edge frame pieces are pivotally supported on the left and right inner edge frame pieces by pivot support means. Therefore, by rotating the left and right outer edge frame pieces relative to the main body, the left and right inner edge frame pieces and the left and right outer edge frame pieces can be separated with the pivot support position provided around the branching point as the center of rotation.

[0021] (Spindle support means) The above-described pivot support mechanism can consist of left and right pins provided on the inside of the left and right outer edge frame pieces, respectively, and left and right holes provided on the outside of the left and right inner edge frame pieces, respectively. That is, the left and right pins can be fitted into the left and right holes to pivotally support the left and right outer edge frame pieces on the main body. Such left and right outer edge frame pieces are positioned at a height h from the lower edge frame piece. S At the branching point, the left and right side edge frame pieces, each with a front view width d, are each with a width d in and width d out (d in +d out =d) can be formed by cutting into left and right inner edge frame pieces and left and right outer edge frame pieces. The left and right inner edge frame pieces can then be integrally molded together with the main body, which consists of an upper side edge frame piece, a lower edge frame piece, and a base plate that are continuous above them.

[0022] Furthermore, the calendar stand of the present invention has a base plate that extends from its lower edge frame piece to a height h b It is cut at position h b The lower leg base plate is connected to the left and right outer edge frame pieces, forming the leg frame. Therefore, by rotating the left and right outer edge frame pieces, which are pivotally supported around the branching point, the leg frame can be separated and the main body can be supported in an upright position. In other words, the calendar stand according to the present invention can be made to stand in an upright position where the main body base plate forms an angle of θ with the mounting surface by rotating the left and right outer edge frame pieces connected by the leg base plate relative to the main body by θ degrees, thereby bringing the lower end of the leg frame and the main body into contact with the mounting surface.

[0023] As mentioned above, conventional calendar cases require sufficient space to display the calendar because the lid is placed on the mounting surface. However, the calendar stand of the present invention only requires the leg frame to make contact with the mounting surface at two points, the lower ends of the left and right outer edge frame pieces, thus saving space on the mounting surface.

[0024] (cut surface) As described above, the left and right outer edge frame pieces are cut at the branching point and below it by a cut surface from the upper side edge frame piece and the inner edge frame piece that is continuous below it. In the calendar stand of the present invention, the cut surface of the lower end of the upper side edge frame piece is a tapered cut surface forming an angle of θ in the negative direction, and the cut surface of the upper end of the outer edge frame piece is a convex cut surface consisting of a front cut surface and a rear cut surface, with the front cut surface being tapered at an angle of θ that abuts against the tapered cut surface, and the rear cut surface that is continuous with it in the negative direction being parallel to the negative direction. Therefore, by bringing the lower ends of the leg frame and the main body into contact with the mounting surface and rotating the left and right outer edge frame pieces (leg frame) by θ, the rear cut surface supports the tapered cut surface of the upper side edge frame piece, and the main body base plate can be supported in an upright position forming an angle of θ with the mounting surface.

[0025] (Bottom corner stopper piece) The calendar stand according to the present invention has left and right lower corner stopper pieces formed at the left and right lower corners of the main body, parallel to the base plate, and the base plate is positioned at a height h from the lower edge frame piece. a A convex stopper base plate cut at the specified position is provided. These lower corner stopper pieces and the stopper base plate are provided parallel to the front and rear of the lower edge frame piece, respectively, and can hold the left and right corners of the front of the lower edge and the rear of the lower edge of the calendar inserted from the upper edge of the main body. If a lower edge stopper is erected in the center of the tip of the lower edge frame piece as in conventional calendar stands, it will block the front of the lower edge of the calendar and hide the company name and other displays that you want to advertise the most. However, with the left and right lower corner stopper pieces of the present invention, only the two corners of the lower edge of the calendar are hidden and the display of the company name and other displays is not obstructed. In addition, the stopper base plate of the present invention can hold the back of the inserted calendar.

[0026] (Gap in the base plate) Furthermore, the convex stopper base plate is positioned at a height h from the lower edge frame piece. a (h a <h b ) and its front view width is formed to be narrower than the distance between the left and right lower corner stopper pieces. The height of the left and right lower corner stopper pieces from the lower edge frame piece is the height of the leg base plate h b The following limitations were imposed. Therefore, the main body, which consists of left and right inner edge frame pieces and upper side edge frame pieces, lower edge frame pieces, left and right lower corner stopper pieces, a convex stopper base plate, and a main body base plate, etc., can be integrally molded, as the positions opposite the left and right lower corner stopper pieces have gaps corresponding to the leg base plate. On the other hand, the leg frame, in which the left and right outer edge frame pieces are connected by the leg base plate, can also be integrally molded. As described above, the molds for molding these main body and leg frame have gaps opposite the left and right lower corner stopper pieces that correspond to the leg base plate. Therefore, in both cases, a mold that slides horizontally relative to the base plate is unnecessary, and the two upper and lower molds only need to move vertically relative to the base plate, so the display case of the present invention can be produced with high efficiency.

[0027] (Gap in the base plate) The calendar stand according to the present invention may have tapered left and right side frame pieces, such that the front viewing width d(y) monotonically decreases as the height y (0 ≤ y ≤ H) from the lower edge increases. By tapering the left and right side frame pieces in this way, the weight at the bottom increases, which can improve the stability of the calendar stand. In addition, it is possible to save on materials and reduce costs through mass production. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0029] Hereinafter, embodiments and examples of the calendar stand according to the present invention will be described with reference to the drawings. The same reference numerals will be used for the same components throughout the following drawings. (1) Configuration of the calendar stand according to the present invention

[0030] (Calendar stand configuration) As shown in Figure 1(a), the calendar stand 1 according to the present invention consists of a base plate 2 with a rectangular outline defined by an outer edge 10e consisting of an upper edge 10u, a lower edge 10d, and left and right side edges 10l and 10r, with a display surface 10P and a back surface 10R (see side view in Figure 2), and a frame piece 20 protruding from the outer edge 10e. Hereinafter, the direction from the back surface 10R of the base plate 2 toward the display surface 10P will be referred to as the "positive direction," and the opposite direction will be referred to as the "negative direction" (see left side view in Figure 2).

[0031] (frame piece) This frame piece 20 includes a lower edge frame piece 20D projecting from the lower edge 10d and left and right side edge frame pieces 20L and 20R projecting from the left and right side edges 10l and 10r, and is projected perpendicular to the base plate 2 in the positive direction. The calendar stand 1 according to the present invention uses the left and right side edge frame pieces 20L and 20R as guides, and the lower end of the calendar 100 inserted from the upper edge 10u is brought into contact with the lower edge frame piece 20D, allowing the calendar 100 to be displayed as shown in Figure 4.

[0032] (Cutting the base plate and side edge frame pieces) As shown in Figures 3(a) and (b), the calendar stand 1 of the present invention has a base plate 2 that extends from the lower edge frame piece 20D to a height h b At position h b The main body base plate 10B is higher, and the height h b It is cut to the lower leg base plate 20B. Also, as shown in Figures 3(a) to (e), from the lower edge frame piece 20D to a height h S Below the branching point P1, the left and right side edge frame pieces 20L and 20R, with a front view width d, each have a width d in and width d out (d in +d out =d) is cut into left and right inner edge frame pieces 202L and 202R (Figure 3(a)) and left and right outer edge frame pieces 203L and 203R (Figures 3(b), (e)) (see Figure 7(a)). [Examples]

[0033] (Tapered side edge frame piece) In this embodiment, the calendar stand 1, as shown in Figure 7(b), has a height H from the lower edge frame piece 20D to the upper edge 10u, and a height h from the lower edge frame piece 20D. S Below the branching point P1, the left and right side edge frame pieces 20L and 20R, with a front view width d, each have a width d in and width d out (d in +d out =d) is cut into left and right inner edge frame pieces 202L, 202R and left and right outer edge frame pieces 203L, 203R. The front view width d of the left and right side edge frame pieces 20L, 20R at a height y (0≦y≦H) from the lower edge 10d or lower edge frame piece 20D is a function of y (d=d(y)), and is tapered, decreasing monotonically as the height y increases.

[0034] In this embodiment, the calendar stand 1 has widths d of the left and right inner edge frame pieces 202L, 202R and the left and right outer edge frame pieces 203L, 203R. in (y) and width d out (y) is d in (y)+d out (y)=d(y), 0≦y≦h S It satisfies the condition.

[0035] In this embodiment, the calendar stand 1 has tapered left and right inner edge frame pieces 202L and 202R, as described above, which increases the weight at the bottom, thereby improving the stability of the calendar stand 1. Furthermore, it saves on materials and can be reduced in cost through mass production.

[0036] (Main body and leg frame) The calendar stand 1 of the present invention is composed of a main body 10 and a leg frame 30. The main body 10, as shown in Figure 3(a), preferably includes left and right upper side edge frame pieces 201L, 201R above the branching portion P1, left and right inner edge frame pieces 202L, 202R that are continuous with the main body 10 below, a lower edge frame piece 20D, and a main body base plate 10B, and is integrally molded. The leg frame 30, as shown in Figure 3(b), is composed of left and right outer edge frame pieces 203L, 203R connected to the leg base plate 20B.

[0037] (Legs together and legs apart) The leg frame 30 is pivotally supported on the main body 10 via a pivot support means 3, which will be described later, and can assume a closed leg state as shown in Figure 1(a) and an open leg state as shown in Figure 1(b). In other words, the calendar stand 1 according to the present invention can reversibly transition from a closed leg state in which the leg frame 30 is stored parallel to the main body 10 (see Figure 1(a)) to an open leg state in which it is separated from the main body 10 (see Figure 1(b)) by the pivot support means 3, which pivotally supports the left and right outer edge frame pieces 203L and 203R (see Figure 3) on the left and right inner edge frame pieces 202L and 202R around the branching part P1 of the main body.

[0038] (operation) As described above, in the calendar stand 1 according to the present invention, the left and right outer edge frame pieces 203L and 203R are pivotally supported by pivot means 3 on the left and right inner edge frame pieces 202L and 202R around the branching part P1 of the main body 10, and by rotating this relative to the main body 10, the leg frame 30 opens up, and in the open leg state the main body 10 can be supported in an upright position (see Figure 1(b)). (2) Orthostatic mechanism

[0039] In this section, using Figures 1 to 3, we will continue to describe the cross-sections 22 of the left and right side edge frame pieces 20L and 20R (upper side edge frame piece 201 and the inner edge frame piece 202 and outer edge frame piece 203) of the calendar stand 1 of the present invention and the pivot support means 3. The calendar stand 1 of the present invention, through the uprighting mechanism combining the pivot support means 3 and the cross-sections 22, can rotate the leg frame 30 relative to the main body 10 to spread its legs and support the main body 10 in an upright position.

[0040] As described above, the calendar stand 1 according to the present invention can be configured such that the main body base plate 10B is in an upright position where it forms an angle of, for example, θ degrees from the mounting surface by rotating the left and right outer edge frame pieces 203L and 203R, which are pivotally supported by pivot support means 3 on the left and right inner edge frame pieces 202L and 202R, relative to the main body 10, thereby bringing the lower ends of the leg frame 30 and the main body 10 into contact with the mounting surface. For example, in order to configure the main body 10 to be in an upright position where it forms an angle of θ degrees from the mounting surface, as shown in Figure 1(b), the cut surfaces 22D (22Df, 22Db) of the outer edge frame pieces 203L and 203R at the branching section P1 must contact the cut surfaces 22U of the upper side edge frame pieces 201L and 201R at an angle of θ degrees, thereby supporting the upper side edge frame pieces 201L and 201R (see Figures 3(c) and (b)). (2-1) Pivoting means

[0041] First, the pivot support means 3 consists of, for example, left and right pins 31L, 31R (see Figures 3(b) and 3(e)) provided inside the left and right outer edge frame pieces 203L, 203R, respectively, and left and right holes 32L, 32R (see Figures 3(a) and 3(c)) provided outside the left and right inner edge frame pieces 202L, 202R, respectively. The left and right holes 32L, 32R preferably penetrate the left and right inner edge frame pieces 202L, 202R. It is preferable to insert the left and right pins 31L, 31R into the left and right holes 32L, 32R so that the left and right outer edge frame pieces 203L, 203R are pivotally supported on the left and right inner edge frame pieces 202L, 202R.

[0042] Alternatively, the pivot support means 3 may be supported by providing left and right holes 32L and 32R in the left and right outer edge frame pieces 203L and 203R, respectively, and providing left and right pins 31L and 31R on the outside of the left and right inner edge frame pieces 202L and 202R, respectively. (2-2) Cut surface

[0043] Next, with reference to Figures 3(a) to (e), the cross-sections 22U at the lower ends of the upper side edge frame pieces 201L and 201R, and the cross-sections 22D (22Df, 22Db) at the upper ends of the outer edge frame pieces 203L and 203R will be described in detail.

[0044] (cut surface) As shown in Figures 3(c) and (d), the upper side edge frame piece 201R and the outer edge frame piece 203R are cut by a cross-section 22 (22U, 22D). In Figure 3(c), the cross-section 22 at the lower end of the upper side edge frame piece 201R is a tapered cross-section 22U that forms an angle of θ in the negative direction. The cross-section 22 at the upper end of the outer edge frame piece 203R, as shown in Figure 3(d), is a convex cross-section 22D that is continuous in the negative direction, consisting of a tapered front cross-section 22Df with an angle of θ in the negative direction that substantially contacts the tapered cross-section 22U when the legs are closed, and a rear cross-section 22Db parallel to the negative direction. [Examples]

[0045] (Legs together) In this embodiment, the calendar stand 1, in the closed leg state shown in Figure 1(a), has a tapered cut surface 22U at the lower end of the upper side edge frame piece 201R and a tapered front cut surface 22Df of the outer edge frame piece 203R that are in contact or parallel with a small gap between them (see Figures 3(c) and (d)). At this time, the main body base plate 10B and the leg base plate 20B are flush with each other, forming the base plate 2 before cutting.

[0046] (Legs spread) On the other hand, in the upright position (spread-leg position) shown in Figure 1(b), the rear cross-section 22Db of the outer edge frame piece 203R abuts against the tapered cross-section 22U of the upper side edge frame piece 201R (see Figures 3(c) and (d)). As described above, the cross-section at the lower end of the upper side edge frame piece 201R is a tapered cross-section 22U that forms an angle of θ in the negative direction, so the upper side edge frame piece 201R can be positioned in an upright position of θ degrees relative to the mounting surface in the spread-leg position.

[0047] Therefore, the calendar stand 1 according to the present invention forms the cut surfaces 22 of the upper side edge frame piece 201R and the outer edge frame piece 203R as a tapered cut surface 22U and a convex cut surface 22D (front cut surface 22Df and rear cut surface 22Db), respectively, so that the upper side edge frame piece 201 and the outer edge frame piece 203 are parallel when the legs are closed, and the angle between the upper side edge frame piece 201 and the outer edge frame piece 203 is set to θ degrees when the legs are open.

[0048] As described above, the calendar stand 1 according to this embodiment can transition between a closed leg state and an open leg state by rotating the outer edge frame pieces 203L and 203R relative to the left and right inner edge frame pieces 202L and 202R, which are pivotally supported by the pivot support means 3. The rear cut surface 22Db of the upper end of the outer edge frame piece 203 supports the tapered cut surface 22U of the lower end of the upper side edge frame piece 201, thereby supporting the main body 10 in an upright position at an angle θ with respect to the mounting surface. (3) Calendar holding mechanism

[0049] This section will continue to describe the mechanism for holding the lower edge of the calendar 100 inserted from the upper edge 10u of the calendar stand 1 of the present invention, using Figures 1 to 3 and Figure 4, etc. The mechanism for holding the lower edge of the calendar 100 of the present invention consists of lower corner stopper pieces 24L and 24R and a convex stopper base plate 12B. (3-1) Lower corner stopper piece

[0050] First, I will explain the mechanism that holds the lower edge of the calendar 100 inserted into the main body 10 from the front.

[0051] The left and right lower corner stopper pieces 24L and 24R shown in Figures 1 to 3 can hold the lower edge of the calendar 100 inserted into the main body 10 from the front. Specifically, the left and right lower corner stopper pieces 24L and 24R are formed parallel to the base plate 2 so as to connect the tips of the lower edge frame piece 20D and the left and right inner edge frame pieces 202L and 202R at the left and right lower corners 10cl and 10cr where the lower edge frame piece 20D of the base plate 2 intersects with the left and right inner edge frame pieces 202L and 202R, respectively (see Figure 3(a)). Therefore, the left and right lower corner stopper pieces 24L and 24R can hold the left and right corners of the lower edge of the calendar 100 inserted from the upper edge 10u from the front, preventing the calendar 100 from sliding forward of the calendar stand 1. [Examples]

[0052] (void) These left and right lower corner stopper pieces 24L and 24R are positioned so that their height from the lower edge frame piece 20D is equal to the height of the leg base plate 20B. b The following is preferable: h is the height of the leg base plate 20B. b By limiting the following, a gap corresponding to the leg base plate 20B can be provided at the corresponding positions of the leg base plate 20B facing the left and right lower corner stopper pieces 24L and 24R in the closed leg position (see Figure 3(a)).

[0053] Therefore, when molding the calendar stand 1 of the present invention, the two molds that mold the main body 10, which consists of the left and right upper edge frame pieces 201L, 201R and the left and right inner edge frame pieces 202L, 202R, the lower edge frame piece 20D, the main body base plate 10B, and the left and right lower corner stopper pieces 24L, 24R, do not need to be slid horizontally relative to the main body base plate 10B, but only vertically relative to the main body base plate 10B, thus enabling the production of the calendar stand 1 of the present invention with high efficiency. (3-2) Convex stopper base plate

[0054] Next, a mechanism for holding the lower edge of the calendar 100 inserted into the main body 10 from the rear will be described.

[0055] As described above, the leg base plate 20B is at a height h from the lower edge frame piece 20D of the main body 10. b It is cut at this position. A portion of the lower edge of this leg base plate 20B is cut to form a convex stopper base plate 12B that is erected from the rear of the lower edge frame piece 20D toward the upper edge 10u of the base plate 10.

[0056] In other words, the leg base plate 20B is at a height h from the lower edge frame piece 20D. a (h a <h b ), and leaving a convex stopper base plate 12B whose front view width is narrower than the distance between the left and right lower corner stopper pieces 24L and 24R, with a height h b It is cut at the position (see Figures 3(a) and (b)). Therefore, the leg base plate 20B is at a height h from the lower edge frame piece 20D of the base plate 2. b It is cut at this position, and its lower end is cut into a concave shape that fits with the convex stopper base plate 12B (see Figure 3(b)). The convex stopper base plate 12B formed in this way can hold the lower edge of the calendar 100, which is inserted from the upper edge 10u of the main body 10, from the rear, preventing it from falling off the base plate 10. [Examples]

[0057] (void) In this embodiment, the convex stopper base plate 12B is positioned at a height h from the lower edge frame piece 20D, as shown in Figure 3(a). a (h a <h b ) and its front view width is formed to be narrower than the distance between the left and right lower corner stopper pieces 24L and 24R. The height of the left and right lower corner stopper pieces 24L and 24R from the lower edge frame piece 20D is set to the height of the leg base plate 20B h bThe following restrictions were imposed, and a gap corresponding to the leg base plate 20B was provided at a position opposite to the left and right lower corner stopper pieces 24L and 24R in the closed leg position.

[0058] In other words, as shown in Figure 3(a), the main body 10 of the calendar stand 1 in this embodiment consists of left and right upper side edge frame pieces 201L, 201R and left and right inner edge frame pieces 202L, 202R that are continuous with the upper side edge frame pieces below, respectively, a lower edge frame piece 20D, left and right lower corner stopper pieces 24L, 24R, a main body base plate 10B, and a convex stopper base plate 12B. The leg frame 30 is constructed by connecting left and right outer edge frame pieces 203L, 203R to the leg base plate 20B, as shown in Figure 3(b).

[0059] The main body 10 and the leg frame 30 shown in Figures 3(a) and (b) can be integrally molded. In this embodiment, the height of the left and right lower corner stopper pieces 24L and 24R from their lower edge frame piece 20D is the height of the leg base plate 20B, h b The following limitations were imposed, and the front view width of the convex stopper base plate 12B was formed to be narrower than the distance between the left and right lower corner stopper pieces 24L and 24R. Therefore, a gap corresponding to the leg base plate 20B can be provided at a position opposite to the left and right lower corner stopper pieces 24L and 24R (see Figure 3(a)), and the two molds for forming the main body 10 only need to move vertically, without sliding horizontally relative to the main body base plate 10B, thereby enabling the production of the calendar stand 1 of the present invention with high efficiency.

[0060] As described above, the lower corner stopper pieces 24L and 24R and the convex stopper base plate 12B function as a mechanism to hold the lower edge of the calendar 100, allowing the lower edge of the calendar 100, which is inserted from the upper edge 10u, to be held from both the front and the rear, and can be easily formed. Unlike the lower edge stopper 522 erected in the center of the tip of the lower edge frame piece of a conventional calendar stand, this holding mechanism does not block the front of the lower edge of the calendar, so it can hold the lower edge of the calendar 100 without interfering with the display of company names, etc.

[0061] The calendar stand according to the present invention has been described above, but the present invention is not limited to the above embodiments and examples.

[0062] Furthermore, the present invention can be implemented in various forms with improvements, modifications, and changes based on the knowledge of those skilled in the art, without departing from its spirit. [Industrial applicability]
