Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 4, the desktop calendar stand 10 according to the present invention mainly includes a storage unit 12 that stores calendar paper sheets 30 and can stand up from the storage unit 12 to hold the storage unit 12 in an inclined state. The leg part 14 and the hinge part 16 that connects the storage part 12 and the leg part 14 are provided. The storage part 12, the leg part 14 and the hinge part 16 are made of, for example, a synthetic resin such as polypropylene. Molded integrally.

  The storage unit 12 supports the back surface of the calendar paper sheet 30 and is supported by the support surface 12a connected to the leg part 14 and the left and right side edges and the lower edge of the support surface 12a. A case structure having an edge portion 12b for supporting the side edge and the lower end edge is configured, and the calendar paper sheet 30 can be accommodated therein. An opening 12c is formed at the center of the support surface 12a, and a thick pedestal 12d projects from the back side of the support surface 12a along the lower end of the opening 12c. A stopper 12e is further projected from a part of 12d (see FIG. 5).

  The leg portion 14 is connected to the support surface 12 a of the storage portion 12 via the hinge portion 16. When the desktop calendar stand 10 is not in use, the leg portion 14 is in a non-stand-up state in the support surface 12a of the storage portion 12 and substantially in the same plane as the support surface 12a, and is almost lying on the opening 12c. ing. In addition, when the desk calendar stand 10 is used, the leg portion 14 is turned 90 degrees or more with respect to the support surface 12a from the non-standing state, and is in a standing state standing with respect to the storage portion 12. A thick pedestal 14a protrudes from the base end of the leg 14, and a stopper 14b is further protruded from a part of the pedestal 14a, and at a portion where the pedestal 14a is not formed, A notch 14d is formed (see FIG. 5).

  As shown in FIG. 5, the hinge portion 16 is housed side by side with the hinge main body portion 18 and the thin hinge main body portion 18 laid between the base 12 d of the housing portion 12 and the base 14 a of the leg portion 14. And a hinge strap portion 20 provided between the pedestal 12d of the portion 12 and the notch portion 14d of the leg portion 14. The number of hinge main body portions 18 and hinge strap portions 20 is arbitrary, and in the case of the illustrated example, two hinge strap portions 20 are provided between three hinge main body portions 18 and adjacent hinge main body portions 18. However, the present invention is not limited to this. For example, one hinge main body 18 and a pair of hinge straps 20 are provided on both sides thereof, or one hinge strap 20 and a pair of hinge main bodies 18 are provided on both sides thereof. It is also possible to provide.

  As shown in FIG. 7A, the hinge main body 18 projects from the top surface of the receiving base 12d projecting from the support surface 12a and the leg 14 when the leg 14 is in the non-standing state. Are connected to the top surface of the cradle 14a, and the first surface portion 18a is substantially flush with the top surfaces of the cradle 12d and 14a, and is opposite to the first surface portion 18a and has a U shape or V shape. A second surface portion 18b. The thinnest part of the hinge body 18, that is, the U-shaped or V-shaped apex of the second surface part 18 b constitutes the rotation center axis 24 for the relative rotation of the leg part 14 and the storage part 12. .

  The hinge strap portion 20 connects the adjacent portion 12h of the concave portion 12g formed on the side surface of the cradle 12d protruding from the support surface 12a and the innermost portion 14e of the notch portion 14d. The adjacent portion 12 h and the back portion 14 e are not on the rotation center axis 24 but are offset from the rotation center axis 24. And the hinge strap part 20 becomes a structure which can be elastically expanded-contracted in the longitudinal direction.

  More specifically, as shown in FIG. 6A, the hinge strap portion 20 is connected to a plurality of annular elastic bodies 22 having a substantially elliptical shape and having the short axis aligned with the longitudinal direction of the hinge strap portion 20. Consists of things. By deforming the annular elastic body 22, the hinge strap portion 20 can elastically expand and contract in the longitudinal direction.

  The structure of the hinge strap portion 20 is not only an elliptical annular elastic body but also a perfect circular shape or other closed annular elastic body, or a spring-like elastic body extending zigzag in the longitudinal direction (FIG. 6). (B)), a plurality of C-shaped elastic bodies connected (FIG. 6C), a plurality of polygonal elastic bodies connected (FIG. 6D), and so on. Any stretchable structure is possible.

  In the desk calendar stand 10 configured as described above, as described above, the leg portion 14 is in a non-stand-up state when not in use, and the calendar paper sheet 30 is stored in the storage portion 12, and the support surface 12 a Since it lies almost lying down in the opening 12c, it is compact in its entirety, which is convenient for its storage and transportation.

  At the time of use, the leg portion 14 is rotated in the standing direction via the hinge portion 16 in order to make the desk calendar stand 10 self-supporting. Then, as shown by the arrow in FIG. 7A, the leg portion 14 rotates about the rotation center axis 24. When the leg portion 14 is pivoted, a portion connected to the back portion 14 e of the notch portion 14 d at one end of the hinge strap portion 20 also draws an arc locus centering on the pivot center axis 24. The length between the arc locus and the portion connected to the adjacent portion 12h of the recess 12g at the other end of the hinge strap portion 20 is not constant, and is 90 degrees or more as shown in FIG. It becomes maximum at the intermediate boundary 28 near the center of the rotation range. In FIG. 7B, the alternate long and short dash line 26 represents an arc locus centering on the rotation center axis 24 of the back portion 14e, and the broken line 27 represents an arc locus centering on the adjacent portion 12h of the back portion 14e. Yes. The intermediate boundary portion 28 corresponds to the place where the distance between the one-dot chain line 26 and the broken line 27 in FIG. In order to respond to this change in length, the hinge strap portion 20 is elastically extended. Relative rotation in the direction toward the non-standing state of the leg portion 14 on the non-standing state side with respect to the intermediate boundary portion 28 with the intermediate boundary portion 28 as a boundary due to the restoring force to return the elastic deformation of the hinge strap portion 20 An urging force for urging the operation is generated, and an urging force for urging a relative rotation operation in a direction toward the standing state of the leg portion 14 is generated on the side of the standing state with respect to the intermediate boundary portion 28.

  Accordingly, when the leg portion 14 is relatively rotated from the non-standing state beyond the intermediate boundary portion 28, the leg portion 14 is rotated in the direction toward the standing state by the biasing force, and the stopper 14b comes into contact with the stopper 12e. Then, since the relative rotation in the direction which goes to the anti-non-standing state of the leg part 14 beyond this becomes impossible, the leg part 14 maintains an upright state. Instead of providing the stoppers 14b and 12e, the restoring force of the hinge strap portion 20 may be zero in the standing state of the leg portion 14, and the standing state of the leg portion 14 may be maintained.

  In this way, the desk calendar stand 10 can be self-supported by the storage part 12 and the leg part 14. It is only necessary to rotate the leg portion 14 at least until it exceeds the intermediate boundary portion 28, and a separate member and an assembling work for maintaining the leg portion 14 in an upright state are unnecessary. be able to.

  Since the notch portion 14d is formed in the leg portion 14, the operation of the hinge strap portion 20 can be prevented from being hindered by the leg portion 14, and the hinge strap portion 20 can be rotated by 90 degrees or more. can do. Moreover, since the hinge strap part 20 is connected with the back part 14e of the notch part 14d, the length of the hinge strap part 20 is securable.

  When the user wants to write on the calendar paper sheet 30 stored in the storage unit 12 during use, the top of the storage unit 12 is pushed down as shown in FIG. As a result, the support surface 12 a is rotated via the hinge portion 16. At this time, the support surface 12a rotates about the rotation center axis 24. Then, as in the case described above, the hinge strap portion 20 is elastically extended, and when the storage portion 12 is relatively rotated beyond the intermediate boundary portion 28 with the intermediate boundary portion 28 as a boundary, the restoring force of the hinge strap portion 20 causes the leg to A biasing force that biases the relative rotational movement of the portion 14 toward the non-standing state is generated. Due to this urging force, the leg portion 14 and the storage portion 12 are simultaneously collapsed, and the leg portion 14 is brought into a non-standing state.

  In this way, the leg portion 14 is in a non-standing state and the storage portion 12 is almost horizontal, so that the user can directly write on the calendar paper leaf 30 with the calendar paper leaf 30 being stored in the storage portion 12. . The user does not need to put in and out the calendar paper sheet 30 from the storage unit 12 one by one, and can easily perform writing without taking time and effort. After the writing is completed, the leg portion 14 can be raised by the urging force of the hinge portion 16 by rotating the leg portion 14 to the intermediate boundary portion 28 as described above.

  In the above example, the storage part 12, the leg part 14 and the hinge part 16 are integrally formed, and the support surface 12a of the storage part 12 supports the back surface of the calendar paper sheet 30 and is connected to the leg part 14. However, the present invention is not limited to this, and the member that supports the back surface of the calendar paper sheet 30 and the member that is connected to the leg portion 14 and is integrally formed with the leg portion 14 may be configured as separate parts.

  Further, the urging force generated when the leg portion 14 is relatively rotated from the standing state to the non-standing state when the leg portion 14 exceeds the intermediate boundary portion 28 is caused by the leg portion 14 to be completely the same as the storage portion 12. It does not need to occur until the surface is reached, and it may disappear on the way or an urging force in the opposite direction may work. In the example of FIGS. 7A and 7B, when the leg portion 14 is completely flush with the storage portion 12, the hinge strap portion 20 is slightly bent, whereby the leg portion 14 is in an upright state. It is urged towards.
