Definitions

  • the present invention relates to a timer and, more particularly, a timer device arranged to actuate a switch at a pre-selected time on pre-selected days of a week.
  • rhythm of human life is controlled by the days of the week besides the time. For example, it is usually necessary to get up at the same time of the day from Monday through Friday in one week. On Saturday and Sunday it is not always necessary to get up at the same time of the day as above.
  • This type of life rhythm can be maintained easily by using a timer device.
  • conventional timer devices have a disadvantage that, when the timer device is once set to the hour of rising and is left as it is, the alarm device such as a buzzer is actuated at the same time every day regardless of the days ofthe week.
  • a calendar day indication member 5 of regular septangular drum shape which bears names of 7 days of a week being engraved on each peripheral face of the drum, is interlocked with the hour drum 4 through a suitable intermittent feed mechanism (not illustrated) and is instantaneously turned every l/7 turn a day.
  • the calendar day indication drum 5 is usually turned at the moment when the time indication changes from 23:59 to 0:00.
  • the timer setting drum 6 has time graduations (24 hours or 12 hours) for the timeto be set being engraved on its peripheral surface and the timer device is set by matching the graduation for the time to be set to the fixed pointer 7. That is, by setting the timer setting drum 6, the switch is closed and the alarm device is operated every 24 or 12 hours at the set time.
  • Numeral 8 designates a calendar adjusting knob
  • numeral 9 designates a calendar setting lever to be described later
  • numerals 10 and 11 designate base plates.
  • Still another object of the present invention is to provide a timer device as mentioned above which can be easily arranged into a conventional clock device having a calendar indicating drum.
  • FIG. I shows a front view of'a digital-indication clock provided with the timer device according to the present invention
  • FIG. 3 shows an enlarged front view of the major part of the timer-device according to the present invention
  • FIG. 8 shows aview corresponding to FIG. 4 but showing a different embodiment.
  • FIG. 1 showing a leaf-type digital-indication, clock provided with the timer device according to the present invention
  • the clock mechanism part has a structure as described in US. Pat. No. 3,697,770.
  • Rotation of a In FIG. 2 numeral 12 designates a microswitch to be operated by a lever 13 which is actuated at the time set by the timer setting drum 6.
  • the switch 12 is connected in series to a micro-switch 14 which is operable by rotation of the calendar day indication drum 5.
  • the micro switch 14 is further connected in series to an electric load 15 such as a buzzer or radio.
  • Reference symbols a and 'a designate power terminals.
  • FIGS. 3, 4, 5 and 6 clearly show thestructure of the device according to the present invention.
  • Numeral l6 designates a hollow cylindrical member secured to one end face of the calendar day indication drum 5 and is made of synthetic resin.
  • seven rectangular holes 16a are provided for slidably inserting seven operating members 17.
  • guide groove portions 16c are provided to engage with each pin 17a of each operating member 17.
  • One side of the guide groove 16c is formed by a side edge of a flexible projecting portion 1612, which is formed as a holding member-for holding the pin 17a at two different positions (a position where the operating member 17 is pulled outward and a position where the member 17 is pushed in toward the center) as clearly shown in FIG. 4.
  • cylindrical member 16 is secured to the calendar day indication drum 5 by screws 19, it is also possible to form this cylindrical member 16 integrally with the calendar day indication drum 5 as shown in FIG. 8.
  • Operating mern bers 17 are movable in radial direction and those pulled-out operating members 17, through 17,, push the switch actuating piece 14a of the microswitch 14 as the calendar day indication drum 5 rotates. Those pushedin operating members 17 and 17 do not push the ing member 17 and projecting portion 16b is as shown in FIG. 5.
  • the lever 9 is manually turned around the shaft 18 mounted to the base plate 11, the operating member 17 can be moved in radial direction through the pin 17a.
  • the timer is actuated only on the desired days of the week, for example on Monday through Friday, when the operating members 17 through 17 for the desired daysof the week are pulled outward and the other operating members 17 and 17 are pushed inward by operating the lever 9 for every day of the week.
  • the desired days of the week for example on Monday through Friday
  • the other operating members 17 and 17 are pushed inward by operating the lever 9 for every day of the week.
  • the micro switch 14 closes only on Monday through Friday as time (days of the week) passes. Therefore, when the micro-switch 14 is connected in series to the microswitch 12 which closes at the set time every day as shown in FIG. 2, the electric load 15 can be actuated at the pre-selected time on Monday through Friday only and can give notice to a man that it is the preselected time.
  • the projecting member 16b formed in the hollow cylindrical member 16 is used for holding the operating member 17 at two different positions respectively.
  • a spring 20 as shown in FIG. 7 having one end of which is fixed to the cylindrical member 16 and also having two curved portions 20a and 20b on the free end which are capable of holding the pin 17a.
  • the operating members 17 as cylindrical pins as shown in FIG. 8 providing a pair of adequately spaced annular grooves 17 17 I7 I7 I7 17 17 17 17 17 17 17 17 and 17 17,", on the circumference near the top of each of pins 17,through 17
  • an endless coil spring 22 wound along the periphery of the cylindrical member 16 and fixed to the cylindrical member by a screw 21 may be engaged alternatively to elastically hold each operating member 17 in either one of two different positions.
  • a timer device comprising a clock device; a calendar day indication member connected to said clock de vice and rotated intermittently by said clock device and having indications of each day of the week provided on its circumference; a cylindrical member fixed to one end of said calendar day indication member; seven operating members having a pin projecting therefrom and being slidably arranged on said cylindrical member along radial directions thereof and being equally spaced; holding members provided to said cylindrical member and capable of holding said operating members in first and second positions; a setting lever selectively engageable with one of said pins to move one of said operating members to either said first or second position; and a switch provided adjacent to said calendar day indication member and closed in accordance with rotation of said calendar day indication member only by those of the operating members which are held in said first position.
  • a timer device in which said holding members are springs fixed to said cylindrical member and having two curved portions engageable with said pin.
  • a timer device in which said holding member is an endless coil spring wound on and fixed to the circumferential surface of said cylindrical portion and engageable with a pair of annular grooves formed on each of said operating members for holding said operating members in the first and second positions, respectively.
