BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case type desk calendar.

[0002]

2. Description of the Related Art Conventionally, a calendar piece cut into a card shape is held,
Various case-type desk calendars have been proposed which include a lid to be displayed and a main body placed on a table, and have a thin case shape when the lid is closed to the main body.

[0005] As an example, as shown in FIG. 5, supporting projections 25 protruding out of the lid are provided at predetermined positions on the left and right side plates of the lid 22 along the longitudinal direction of the left and right side plates of the main body 23. The main body 23 holds the lid 22 by fitting into the elongated through-hole 24 provided.

However, in the case-type desk calendar as described above, the supporting projection 25 of the lid 22 and the fitting portion of the through hole 24 of the main body 23 have play in the horizontal direction. When a hand or the like is caught on the lid 22 and an external force is applied, the main body 23 and the lid 22 come off,
There is a problem that the calendar piece 9 easily jumps out of the lid body 22 and falls apart, and it is troublesome to arrange the calendar pieces that have fallen apart every month and put them in the lid body 22. I was

The present invention has been made in order to solve the above-mentioned drawbacks, and provides a case-type desk calendar which can securely hold a main body and a lid when the case-type desk calendar is used as a calendar. The purpose is to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the case type desk calendar of the present invention will be described below in detail with reference to the drawings. FIG.
It is a perspective view showing an example using the case type desk calendar of the present invention as a desk calendar. 1 is a case type desk calendar of the present invention, 2 is a calendar holding portion for holding a calendar piece 9 cut into a card shape,
Reference numeral 3 denotes a base that can hold the calendar holding unit 2 in a state where the calendar holding unit 2 stands up.

In FIG. 2, (a) is a perspective view of a calendar holding portion, (b) is a right side view of the calendar holding portion,
(C) is a longitudinal sectional view along line AA of (a). The calendar holder 2 is provided with a substantially U-shaped groove on the bottom of the substrate 5, and the groove includes, for example, a surface plate 4, a bottom plate 7, and left and right side plates 6. The upper end of the groove is opened to form a calender insertion opening 8. From the calendar insertion opening 8, the card pieces 9 cut into a card shape and inserted into the calendar holding portion 2 can be viewed from the front plate side.

[0009] In the calendar holding portion 2, convex portions 10 are provided at predetermined positions outside the left and right side plates 6. The cross-sectional shape of the convex portion is an elliptical shape in this embodiment, but may be a polygonal shape (for example, a square, a rectangular shape, a rhombus, a hexagon, etc.). As shown in FIG. 2 (b), the angle θ between the long axis of the convex portion 10 and the vertical direction can be arbitrarily changed.
A range of 15 to 25 ° is preferred. Note that the left side view of the calendar holding unit 2 appears symmetrically with FIG. 2B.

In the calendar holding section 2, two support members 14 are provided at predetermined positions inside the substrate 5, and fixed projections 15 are provided at predetermined outside positions of the support members 14.

A substantially quadrangular hole 16 is provided at the center of the substrate 5. The hole 16 may have any shape and size as long as it is smaller than the calender piece 9.
By providing the holes 16, the case-type desk calendar 1 can be reduced in weight and can contribute to resource saving.

FIG. 3A is a perspective view of a base.
(B) is a longitudinal sectional view along the BB line of (a). The base 3 has left and right side frames 18 on three sides of a substantially quadrilateral base 17.
And the bottom frame 19 is suspended from the base 17.

In the base 3, a fitting recess 11 is provided on the inner surface on one end side of the left and right frames 18, and a pivoting recess 12 is provided following the fitting recess 11. The fitting recess 11 forms a linear groove, and the pivoting recess 12 forms a circular groove. Further, the fitting recess 11 allows the protrusion 10 to be fitted in and removed from the long axis or the long side direction. Thus, the opening of the fitting concave portion 11 is formed to have a size slightly larger than the diameter of the convex portion 10 in the short axis or short side direction. Further, the pivoting concave portion 12 is slightly larger than the diameter of the convex portion 10 in the long axis or long side direction such that the convex portion 10 fitted from the fitting concave portion 11 can rotate. It is formed in a circular shape having a size that increases.

The base 3 has three recesses 13 at predetermined locations on the inner surface of the left and right frames 18.
Are provided perpendicular to the base 17.

FIG. 3 shows a case in which three concave portions 13 are provided on the right and left side frames 18, respectively.
May be formed so that the position where the calender holding portion 2 is erected can be finely adjusted.

The width of the concave portion 13 is set so that the convex portion 10 can be fitted and removed in the direction of the long axis or the long side.
Is formed to have a size slightly larger than the diameter in the short axis or short side direction.

In the base 3, fixed holes 20 are formed at predetermined positions of the left and right side frames 18, and are formed so as to be fitted with the fixed convex portions 15. Further, fixing portions 21 are provided at predetermined positions of the left and right side frames 18. Thereby, when the calendar holding part 2 and the base part 3 are engaged with each other and integrated, it is possible to hold the integrated case, and there is no possibility that the case is collapsed even when pressure is applied to the case.

As the calendar holding portion 2 and the base 3 constituting the case type desk calendar 1 of the present invention, synthetic resin or the like is used, but hard vinyl chloride is preferable because it is inexpensive and easy to manufacture.

Next, a method of using the case type desk calendar of the present invention will be specifically described. (1) As shown in FIG. 4 (a), the case-type desk calendar 1 has a state of a case in which the calendar holding unit 2 and the base 3 are integrated with each other during transportation.

(2) The pivot recess 12 has a circular shape and the projection 1
0, and when used, the calendar holding portion 2 is rotated until the long axis direction of the convex portion 10 coincides with the direction of the groove of the fitting concave portion 11 (FIG. 4B). ), The protrusion 10 is pulled out from the pivot recess 12 through the fitting recess 11, and the calendar holding section 2 is removed upward with respect to the base 3.

(3) The convex portion 10 of the calendar holding portion 2 is
It is selected from the plurality of recesses 13 and fitted from the opening of the recess 13.

The convex portion 10 has an elliptical or polygonal shape, and the concave portion 13 is provided with a linear groove. Therefore, when the convex portion 10 is fitted into the concave portion 13, the convex portion 10
, The calendar holding portion 2 can be securely held on the base portion 3, and even if external force is applied to the calendar holding portion 2, the calendar holding portion 2 and the base portion 3 can be held.
Does not come off.

Further, it is possible to hold the calendar holding portion 2 in a state where the calendar holding portion stands up, and furthermore, the left and right side frames 18
The base 17 surrounded by the bottom frame 19 and the bottom frame 19 can be used as an accessory case for stationery and the like, and is also effective for organizing the desk.

[0024]

As described above, according to the present invention, the calender holding portion in which the calender pieces are inserted can be securely held in a state where the calender holding portion stands up on the base portion.
