The backing of the mount which is held and has the second equi-hole formed at a position corresponding to the first through-hole, and the back of the flat board which protrudes from the back and is press-fitted into the first and second through-holes. And a pair of support legs protruding from the base plate by a predetermined length from the base plate, wherein the support leg is a taper cylinder body that is detachable from the substrate and narrows from the base end portion on the substrate side toward the tip end, The tip of the support leg has a spherical shape continuing to the tapered body, and the diameter of the base end is larger than the diameter of the first and second through holes, and the diameter of the tapered body is large. The diameter of the smallest diameter part is smaller than the diameter of the first and second through holes. Configuration was "that is obtained by it said.

The calender sheets are overlapped and the support legs of the leg are inserted into the first and second through holes. Since the support leg is formed in a tapered tubular shape and the diameter of the minimum diameter portion of the tapered body is smaller than the diameter of the first and second through holes, the support leg is -Easily penetrate the second through hole. However, since the diameter of the base end of the support leg is larger than the diameter of the first and second through holes, the support leg is forcibly fitted into the first and second through holes. By inserting the support legs, the support legs are press-fitted into the first and second through holes, the back surface of the substrate comes into contact with the front surface of the calendar sheet, and the tips of the support legs are provided from the back surface of the mount (1) in a predetermined manner. It becomes a mode of projecting the length.

The support leg is forcibly press-fitted into the first and second through holes up to the base end portion thereof, so that the leg fitting is mounted on the mount and the mount by frictional force with the first and second through holes. It is held and fixed on the calendar sheet. Therefore, the calendar sheet is sandwiched between the substrate and the mount and held on the mount. On the other hand, the tip of the support leg has a spherical shape that is continuous with the tapered body, and protrudes from the lower part of the back surface of the mount by a predetermined length. You can

Since a part of the lower portion of the calendar sheet is only covered with the substrate, articles can be directly written on the calendar portion of the calendar sheet. You can replace the calendar sheet by removing the legs. Depending on the shape of the second through hole, the calendar sheet can be replaced without removing the leg.

Even when the size of the calendar sheet or the mount is changed, the calender sheet is held on the mount by a common leg simply by providing the first and second through holes so as to match the supporting legs. Then, the whole can be set in an inclined posture. Further, since the support leg of the leg is detachably attached to the substrate, the support leg can be detached from the substrate when not in use.

The invention according to claim 2 is the structure of the invention according to claim 1, wherein "a pair of cylindrical projections is provided on the back surface of the substrate, and the cylindrical projections are provided on the base end of the supporting leg. The parts are removably and tightly fitted together ". The outer diameter of the cylindrical projection is made substantially equal to the inner diameter of the base end portion of the support leg that is the tapered cylindrical body. Thus, when the base end portion of the support leg is forcibly fitted onto the tubular projection, the support leg is tightly fitted to the tubular projection of the substrate, and the support leg is forcibly fitted to the base plate. The supporting leg can be detached from the substrate when it is pulled away from the substrate.

[0011]

[Effect of device]

 As described above, in the invention according to claim 1 of the present invention, since the calender sheet (S) (S) can be held on the mount (1) by the legs, the calender sheet (S) (S) can be held correspondingly. The number of parts is smaller than the conventional one. Further, even if the size of the calendar sheet is changed, it is possible to handle calendar sheets of various sizes by using the common leg.

Further, when the desk calendar is used for advertisement, if the desired printing is performed on the board, various advertisements can be made on the common calendar sheet just by changing the printing on the board. It becomes easy to use. Since the desk calendar can be circulated with the supporting legs removed from the substrate, the bulkiness at the time of distribution or inventory can be reduced.

According to a second aspect of the present invention, the support leg can be attached to and detached from the substrate by fitting or pulling the support leg into a cylindrical protrusion of the substrate. In addition to the effect of the invention, the effect of easily assembling and disassembling the leg is added.

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, a leg made of biodegradable plastic and a mount (1) made of cardboard are used. As shown in FIGS. 3 and 4, the leg is a plate-shaped substrate (21) which is set to be slightly shorter than the lateral width of the calendar sheets (S) (S) and has a substantially rectangular shape as a whole, and the substrate (21). ) And the supporting legs (22) (22) in the shape of a taper cylinder protruding from both ends of the back surface of the substrate) .The surface of the substrate (21) is provided with a display for advertisement by a hot stamp or the like. In addition, cylindrical projections (23) (23) for fitting the support legs (22) (22) are provided on the back surface thereof. The inner diameter of the base end portion of the support leg (22) substantially coincides with the outer diameter of the tubular projection (23) and is closely fitted to each other. Is molded into a spherical shape continuous with the tapered barrel.

According to the embodiment of the present invention, the substrate (21) is a horizontally long rectangular plate-like body having a horizontal width of 82 mm and a vertical length of 15 mm. The dimensional relationship is such that the centers of the cylindrical protrusions (23) (23) are located respectively. The outer diameter of the base end of the cylindrical projection (23) is 7 mm, and is slightly tapered so that the tapered cylindrical support leg (22) can be closely fitted.

On the other hand, the inner diameter of the base end portion of the support leg (22) is set to 7 mm in conformity with the outer diameter of the cylindrical projection (23), and the outer diameter is set to 10 mm. The total length is 42 mm. As shown in FIG. 5, the calender sheet (S) supported by the legs is a square sheet having a side length of 120 mm, and the mount (1) supporting the calender sheet from the back side is the calender sheet ( It is formed larger than S), and its lower side is set so as to match the lower side of the calendar sheet (S).

Near the lower side of the calendar sheet (S) and the mount (1), there are first and second through holes (11a) (11b), which are a pair of circular holes having a diameter of 9.5 mm, and the leg parts. The support legs are penetrated at intervals corresponding to the intervals. In this embodiment, the calender sheets (S) and (S) are overlapped with each other, and the backing sheet (1) is arranged behind the calender sheets (S) and (S), and the first through holes (11a) provided in the calender sheet (S) are provided. ) And the second through hole (11b) provided in the mount (1) are aligned with each other. Then, the support legs (22) (22) of the leg are inserted from the front surface side of the calendar sheet (S) so as to penetrate the first and second through holes (11a) (11b). The outer diameter of the base end of the support leg (22) is 10 mm as described above, and the direct diameter of the first and second through holes (11a) (11b) is 9.5 mm. By forcibly inserting 22) and (22) into the first and second through holes (11a) and (11b), the support legs (22) and (22) are made into the first and second through holes (11a). ) (11b) will be press-fitted.

Thus, when the support legs (22) (22) are press-fitted into the first and second through holes (11a) (11b), the leg fittings are connected to the first and second through holes. By the frictional force between the peripheral edges of (11a) and (11b) and the support legs (22) and (22), the calender sheets (S) and (S) and the mount (1) are fixed in a tightly fitted state. Become. In other words, the calendar sheets (S) (S) are sandwiched between the substrate (21) and the mount (1).

Further, at this time, as shown in FIG. 6, the tips of the supporting legs (22), (22) project from the back surface of the mount (1) and come into contact with the tabletop. Since the lengths of the support legs (22) (22) are as described above, the projection point of the entire center of gravity onto the table is determined by the lower leg of the mount (1) and the table, and the supporting leg (22). 22) It will be located between the tip of (22) and the contact part of the tabletop. Therefore, as shown in FIGS. 6 and 7, the whole can be supported in a tilted posture in a stable state.

As described above, when the support legs (22) and (22) are press-fitted into the first and second through holes (11a) and (11b), as shown by the two-dot chain line in FIG. Since the base plate (21) of the leg is covered in the vicinity of the lower side of the calendar sheet (S), the calender section ( S ₁ ) should be provided.

When the moon changes, the above-mentioned footwear is pulled out from the calendar sheet (S) (S) and the mount (1). Then, the calendar sheet (S) (S) and the mount (1) are separated, the calendar sheet (S) of the corresponding month is positioned at the uppermost layer, and the leg is fitted again. In addition, since the legs are made of biodegradable plastic and the other parts are made of paper, even if they are discarded as they are, they will all be biodegraded by microorganisms and animals. , Does not remain semi-permanently.

When the size of the desk calendar is changed, the size of the above-mentioned calendar sheet (S) (S) and the size of the mount (1) are changed accordingly, and the calendar sheet (S) is changed. Simply by drilling the first through holes (11a) (11a) of (S) and the second through holes (11b) (11b) of the mount (1) to the support legs (22) (22), You can use the leggings as they are. Specifically, the projection point of the center of gravity of the entire desktop calendar onto the desktop is the contact area between the bottom side of the mount (1) and the desktop and the contact area between the tips of the support legs (22) and (22) and the desktop. If the range is located between the two, it can be accommodated by a common leg.

Although the mount (1) is made of thick paper, it may be injection-molded with a plastic sheet. In this case, in order to reduce the material cost, as shown in FIG. 8, the mount (1) is set to a size such that it is covered by the calendar sheets (S) (S). An opening (K) may be provided. Further, although the first through holes (11a) (11a) of the calendar sheets (S) (S) are circular holes, they may be notched holes as shown in FIG. In this case, when the month changes and the topmost calendar sheet (S) is changed, the calendar sheets (S) (S) can be replaced without removing the legs.

In this case, as shown in FIG. 10, the mount (1) is molded with a plastic sheet to provide a support member (12) in each second through hole (11b), and the support leg (22) is attached. If the second through hole (11b) of the mount (1) and the support member (12) are press-fitted, the calendar sheets (S) (S) can be replaced more easily. When the dimensions of each part are set to the above-mentioned dimensions, the leg including the substrate (21) and the pair of support legs (22) and (22) becomes the minimum required size. Further, since the diameter of the base end portion of the support leg (22) is set to be larger than that of a normal punch hole, even if it is repeatedly inserted into and removed from the calendar sheet (S) (S) group, this The fitting part between the calendar sheet (S) (S) and the support leg (22) is hard to loosen. Further, when the leg is used to stand, the desk calendar stands up stably, stands in a posture that is easy to see, and does not tilt excessively.
