Description

    The present invention relates to an apparatus for automatically supplying a fixed amount of granular bait to a pet at a fixed time.

  Timed and automatic feeding to pets requires a complicated mechanism using a timer with electric contacts and an electric motor.

  When an electric motor is used, a complicated mechanism is required, such as a timer for operating the motor. Therefore, the present invention uses the rotational force of the rotating body as the power to control the supply of food, and enables a fixed-quantity automatic feeding with a simple structure to solve the above-mentioned drawbacks.

  As described above, the granular feed can be released without using an electric motor or the like, so that automatic quantitative feeding can be performed at a fixed time with a simple structure. Since the bait is allowed to fall down, if it is installed at the upper end of a pet circle or the like, mischief by the pet due to the odor leakage of the bait can be prevented. In addition, because it does not take a place, you can use the pet ark effectively.

In order to solve the above problems, the present invention is a device comprising a rotating body, a slide bar, and a bait box,
The rotating body has a structure in which a gear is provided on a rotating shaft that rotates once in a predetermined time. Since the number of teeth of the gear need not be specified, the simplest single tooth is used in the embodiment.
The slide bar is provided with at least one or more racks, and in order to clearly show the slide part that can slide in a substantially horizontal direction, the slide part is indicated by a thick line in FIG. The slide bar is slid in the rotation direction by the rotation of the gear in the rotating body.
The bait box is divided into at least one or more bait storage units, and each bait storage unit is pre-supplied with an appropriate amount of bait for a pet meal. At the lower end of each bait storage part, a pivotable opening / closing plate is provided, and the opening / closing plate is closed by a slide bar until a set time.
Due to the rotation of the gear in the rotating body, the gear and the rack provided on the slide bar come into contact with each other, and the slide bar is moved substantially horizontally in the gear rotation direction. The movement of the slide bar causes the rear end of the slide bar to pass under the opening / closing plate of each bait storage unit, so that the opening / closing plate is opened by the weight of the food, thereby supplying a predetermined amount of food to the pet. If the slide bar is provided with a plurality of racks so that the slide bar moves by one bait storage part of the bait box when the rotating body makes one rotation, the feed is repeated every predetermined time.
The opening / closing plate has a double structure of a first opening / closing plate having a rotating shaft at the rear end with respect to the sliding direction of the slide bar and a second opening / closing plate having a rotating shaft at the front end with respect to the sliding direction.
The second opening / closing plate supports the weight of the bait, and the first opening / closing plate supports the second opening / closing plate from the bottom near the rotating part, so that the majority of the weight of the bait is the axis of the first opening / closing plate and the second opening / closing Hanging on the axis of the board. The first opening / closing plate is in contact with the slide bar at the rear end with respect to the moving direction of the slide bar, but the weight of the bait hardly hangs on the slide bar, and the slide bar can slide smoothly.
When the slide bar slides, the rear end thereof passes through the first opening / closing plate, so that the first opening / closing plate is opened by its own weight. In conjunction with the opening of the first opening / closing plate, the second opening / closing plate located thereon is opened by the weight of the bait and the bait falls.
The combination of these parts makes it possible to perform fixed-quantity automatic feeding with a small rotational force of the rotating body.

A commercially available timepiece device can be used as the rotating body. If the second hand and the minute hand are removed from the timepiece device and only the hour hand is left, it becomes a single-tooth rotating body with one gear rotating in 12 hours. This is the power for driving the rack. Dogs and cats usually feed twice a day, every 12 hours in the morning and evening, so the hour hand of a clock that rotates once in 12 hours can be used as power.
When the rack position of the slide bar matches the width of each storage part of the bait box and a plurality of racks are provided,
Since the rack bar can be moved at equal intervals every 12 hours, the number of feedings can be set as needed by increasing the number of feeding storage units.
The size of the feeding storage part is determined by the pet's weight, etc., but if it is within the size range, the owner determines the amount of food to be fed once and replenishes a fixed amount of food by replenishing the food storage part in advance Can do.
The material for the bait storage, slide bar, and opening / closing plate is made of plastic that has low friction and hygroscopicity and is hygienic and lightweight.

An embodiment will be described below with reference to the accompanying drawings. Reference numeral 1 denotes a commercially available timepiece device in which the second and minute hands are removed. 2 is an hour hand. Needless to say, the hour hand rotates once in 12 hours. When the hour hand reaches around 5 o'clock, it comes into contact with 4 racks A of the 3 slide bars, and by the hour hand, the 3 slide bars are pushed to the left in the figure, and the hour hand is around 7 o'clock. The position of the rack is determined so that the right end of the three slide bars passes the left end of the first opening / closing plate before the hour hand leaves the rack. The right end of the first opening / closing plate is rotatable, and is released by its own weight when the rack bar has passed. If the first opening / closing plate is opened, the 8 second opening / closing plate which is positioned on the first opening / closing plate and whose left end is rotatable is also opened. Since a predetermined amount of food is supplied to the food storage unit, the food falls by its own weight and is supplied to the pet.
At that time, 5 racks B have moved to the place where 4 racks A were present, and by repeating this, automatic feeding can be continuously performed every 12 hours.

It is a front view which shows the Example of the fixed-quantity automatic feeding apparatus for pets of this invention. The bait storage portion is a cutaway cross-sectional view. A bold line is used to clearly indicate the slide part of the slide bar. The black dots on the first opening and closing plate indicate the axis of rotation.
