Calendar pen

A calendar pen has an outer cover having multiple windows and multiple first indicators formed thereon, an inner cover rotatably received in the outer cover and having multiple rows of marks peripherally formed thereon and each corresponding to the windows and a rotator rotatably mounted on the inner cover and having a plurality of second indicators selectively aligning with the arrow of the outer cover, such that a user will have the exact date of the day by just rotating different part of the pen.

FIELD OF THE INVENTION
 The present invention relates to a calendar pen, and more particularly to a
 calendar pen enabling a user to know the exact date, month and year. The
 pen has an outer cover provided with multiple windows in the periphery
 thereof, an inner cover rotatably received in the outer cover and having a
 series of marks that stand for the date of the week and a rotator
 rotatably connected with the outer cover and having a series of marks that
 stand for the months of the year, such that with the relative among the
 outer cover, inner cover and the rotator, the user is able to keep track
 of the exact date, month of the year without checking through the calendar
 from time to time.
 Description of Related Art
 Normally, a pen is only used in writing and not other function whatsoever.
 However, due to different requirement of various users, keeping track of
 the exact date of the week, the month or even the year is quite important
 to some users. Therefore, some users will have a pocket calendar to
 provide the exact date at any time necessary. As we all know that carrying
 a pocket calendar is not convenient for the users who travel a lot.
 Because light weight and easy-to-go luggage is the most important factor
 to a person who travels a lot, such that carrying a pocket calendar will
 only add a burden to the person. To overcome the shortcomings, the present
 invention tends to provide an improved pen to mitigate and obviate the
 aforementioned problems.
 SUMMARY OF THE INVENTION
 The main objective of the invention is to provide an improved pen having an
 outer cover provided with multiple windows defined in an outer periphery
 thereof, an inner cover rotatably received in the outer cover and having
 series of marks thereon and a rotator rotatably connected with the outer
 cover and having a plurality of marks that stand for the month of the
 year, such that with the relative rotation among the outer cover, the
 inner cover and the rotator, the user is able to know the exact date of
 the day.
 Other objects, advantages and novel features of the invention will become
 more apparent from the following detailed description when taken in
 conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
 With reference to FIG. 1 and FIG. 2, a calendar pen constructed in
 accordance with the present invention has an inner cover 1, an outer pen 2
 having the inner cover 1 rotatably received therein, a rotator 3 rotatably
 mounted on the inner cover 1, a cone-headed cover 4 threadingly connected
 with an end of the inner cover 1 and a core 5 securely received in the
 inner cover 1 and the cone-headed cover 4.
 The inner cover 1 has two flanges 12,13, a space 11 defined between the two
 flanges 12,13, a threaded hole 14 defined adjacent to a pattern area 10
 which is peripherally formed 20 on the outer surface of the inner cover 1,
 multiple rows of marks 15 peripherally formed on the inner cover 1 and
 each being the date of the week, an extension 16 integrally extending out
 therefrom and having a diameter smaller than that of the inner cover 1.
 The outer cover 2 has multiple windows 21 defined in line in the periphery
 thereof, multiple first indicators 22 peripherally formed thereon and each
 being the number of the month and an arrow 23 formed near one end thereof.
 The windows 21 each corresponds to one row of the marks 15 of the inner
 cover 1.
 The rotator 3 rotatably received between the flanges 12,13 and has multiple
 second indicators 31 annularly formed on the outer periphery thereof.
 The cone-headed cover 4 has a threaded head corresponding to the threaded
 hole 14 of the inner cover 1, such that when the pen of the invention is
 assembled, the cone-headed cover 4 is able to be screwed onto the threaded
 hole 14 of the inner cover 1. The cone-headed cover 4 further has a hole
 40 defined in one end thereof and a spring 41 compressibly received
 between the cone-headed cover 4 and the inner cover 1. The core 5 has an
 end having a diameter slightly smaller that of the hole 40 of the
 cone-headed cover 4, such that the end of the core 5 is able to
 selectively extend out from the hole 40.
 The calendar pen of the invention further has a controlling device to
 control the core 5 to selectively extend out from the hole 40. The
 controlling device comprises a positioning disk 7, a control member 8, a
 spring 9 and a cap 6, which are sequentially inserted in the outer cover
 2. However, because the function and movement of the controlling device is
 conventional in the art, detailed description thereof is omitted.
 When the calendar pen of the invention is in assembly, the spring 41 is
 inserted into the cone-headed cover 4 and then the cone-headed cover 4 is
 screwed onto the inner cover 1. The core 5 is then inserted into the inner
 cover 1 and the cone-headed cover 4. Because the material chosen to make
 the rotator 3, the rotator 3 is able to slide over the flange 13 or 12 and
 receive in the space 11 between the flanges 12,13. Thereafter, the outer
 cover 2 allows the inner cover 1 to be received therein until the end
 having the arrow 23 engages the flange 13. The controlling device, of
 course, is assembled in the outer cover 2 before the inner cover 1 is
 inserted into the outer cover 2.
 After assembly, the user is able to hold the pattern area 10 and rotate the
 rotator 3 to align one of the second indicators 31 with the arrow 23 of
 the outer cover 2. Thereafter, the user holds the rotator 3 and the outer
 cover 2 and rotates the pattern area 10 to align one of the marks 15 that
 stands for the date of the week with one of the windows 22 that has a
 first indicator 22 corresponding to the first indicator 31. After the
 rotation of the parts of the pen is finished, the user then has a pen that
 is able to indicate the date of the week and the month of he year.
 It is to be understood, however, that even though numerous characteristics
 and advantages of the present invention have been set forth in the
 foregoing description, together with details of the structure and function
 of the invention, the disclosure is illustrative only, and changes may be
 made in detail, especially in matters of shape, size, and arrangement of
 parts within the principles of the invention to the full extent indicated
 by the broad general meaning of the terms in which the appended claims are
 expressed.
