Gyroscope base

Abstract

To facilitate attachment and detachment of a lid by storing a ring that makes holding of a string that performs rotary drive of a disc and an end of the string easy in a pedestal of a gyro device, prevent injury of fingers and protect nails from a wound.SOLUTION: C-face machining or R-face machining is applied to a trench of a cavity in the columnar shape formed on a pedestal bottom surface. There are an effect that suppresses a graze even when the back of a finger contacts the trench of the cavity, and an effect that suppresses a wound when a nail contacts. Since a lid attached to the cavity easily slips, insertion of the lid may be shallow. The lid made of a material of sponge has the columnar shape, and the outer diameter is 1.1 times to 1.2 times of the pedestal bottom surface cavity diameter. The lid whose thickness is 1.1 times to 1.2 times of the cavity depth expands in the dome shape and facilitates gasping and detaching. There is no need to insert two fingers to the cavity. A pedestal of a gyro device includes an effect that protects the fingers double and enables the safe work.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a pedestal that is safe, easy to store and take out, and has a storage space for obstructive drive members when a gyro device is used as an ornament on a shelf or the like.

Background Art

[0002] There is a gyroscope (FIG. 5) in a device that rotates a disk by winding a thread around a shaft and pulling the end of the thread. While the disk is rotating at high speed, the disk axis maintains a constant direction even when the posture of the outer frame ring is changed, and when a force is applied to change the angle of the disk axis rotating at high speed, the axis acts in a direction 90 degrees different and has the property of precession in which the angle changes. (Yukimi Maehata, "Gyrocompass and Autopilot", Nariyama-do Shoten Co., Ltd., 2013). There is also a toy globe top (Japanese Patent No. 6033481, FIG. 1) or (FIG. 6). While the disk is rotating at high speed, it has the property of maintaining its posture without falling even in a nodding state called precession motion. These two types are defined as gyro devices, excluding gyrocompasses equipped with power and electronic gyro sensors for detecting angular velocity.

[0003] The shape of the gyro device has the charm of a shape that is not naturally seen, and it is considered that its uses will expand if it is used as an ornament on a shelf or the like. When used as an ornament, the thread for rotating the disk and the ring for making it easy to hold the end of the thread become obstructive objects. Storing them in another place may cause loss.

[0004] It is considered that the thread for rotating the disk and the ring (hereinafter referred to as "drive member") for making it easy to hold the end of the thread may be stored in the pedestal of the gyro device.

[0006] [Non-Patent Document 1] "Gyrocompass and Autopilot" by Yukiya Maehata, Seizando Shoten Co., Ltd., 2013. [Overview of the project] [Problems that the invention aims to solve]

[0007] The problem we are trying to solve is that when the drive component is housed in the gyro device's base, it is difficult to store and remove, and there is a risk of injuring one's fingers.

[0008] Since this is an ornament meant to be displayed on a shelf or similar surface, the drive components must be concealed. The storage location will be a cavity in the base. The size of the cavity will be determined by the size of the drive components. The outer shape and size of the base will be roughly determined by the size of the cavity. If the drive components are housed in the cavity, a lid will be necessary. The lid should be easy to store and retrieve, and also easy to manufacture and inexpensive. After consideration, it was determined that soft polyurethane foam (hereinafter referred to as "sponge") would be suitable for the lid. It can also support the contents with its appropriate elasticity. Once the lid material is decided, the depth of the cavity in the base will be roughly determined. It was set to approximately 18.0 mm.

[0009] Experiment 1 was conducted by creating a cylindrical prototype lid with an outer diameter of 27.5 mm (1.1 times the base cavity diameter of 25.0 mm) and a thickness of 15.0 mm (two-thirds the cavity depth). When the drive component was housed inside, it was found that the lid was difficult to grasp when attaching and removing it. The lid is recessed into a deep position within the cavity. This is because two fingers cannot fit into the cavity, which has an inner diameter of 25.0 mm. On the other hand, the back of the fingers sometimes rubbed against the edge of the cavity, causing abrasions, or nail polish on the fingernails sometimes touched and scratched the skin. (Figure 4) This is because the edge has a sharp, angular shape.

[0010] The goal is to house the drive components in the unseen base of the pedestal to facilitate the attachment and removal of the lid. Furthermore, the pedestal should be designed to allow for safe and injury-free operation. [Means for solving the problem]

[0011] The present invention involves chamfering or rounding the edges of a cylindrical cavity in the base. This is the first method. The outer diameter of the lid, made of sponge, is 1.1 to 1.2 times the diameter of the cavity in the base. The thickness is also 1.1 to 1.2 times the depth of the cavity. This is the second method. [Effects of the Invention]

[0012] According to the present invention, the first means is to improve the sliding between the lid, which has an outer diameter larger than the cavity diameter, and the cavity. When the base is placed on a flat surface, the lid is pushed into the cavity by the weight of the base and adheres tightly to the flat surface such as a shelf. Therefore, the lid inserted into the cavity does not need to be very deep. At this time, even if the back of a finger or a fingernail touches the edge of the cavity, it is safe as the shape is chamfered or rounded, preventing injury or nail damage.

[0013] The second method involves lifting the base from a flat surface such as a shelf, causing the lid to bulge out beyond the depth of the cavity, creating a dome shape. The bulging lid is easy to grasp and remove. There is no need to put your fingers into the cavity. The bulging lid gets caught between the edge of the cavity and your fingers, preventing injury.

[0014] The drive components are housed in an invisible cavity at the bottom of the base. The first and second methods facilitate the attachment and removal of the lid. Furthermore, the base is designed to allow for safe and injury-free operation. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] When the pedestal of a gyro device is used as an ornament on a shelf or the like, the main part is composed of a hollow bottom surface in a cylindrical shape made of metal and a cylindrical sponge lid that closes the hollow.

[0017] The ring of the drive member to be housed assumes an outer diameter of 20.0 mm. Therefore, the inner diameter of the hollow is set to 25.0 mm. Since the depth requires the area where the lid contacts, it is set to 18.0 mm. The hollow bottom surface of the pedestal in a cylindrical shape has an inner diameter of 25.0 mm and a depth of 18.0 mm. The outer shape, in terms of height, width, and depth, looks good when it is about half or less of the main body.

[0018] Since the lid needs to support the stored item elastically by contacting the inner surface of the pedestal hollow, the material is made of sponge. It has appropriate shrinkage and elasticity, is easy to process, and is inexpensive.

[0019] Experiment 2 was conducted with a 0.5 mm C-surface machining on the edge of the cylindrical hollow. Even if the fingernail hits the edge of the hollow, it will not be scratched. Also, the effect that it is not easily damaged even when the nail touches it was confirmed. Also, when the drive member was housed and the lid was shallowly attached and the pedestal was placed on a flat surface, it was found that the lid with an outer diameter larger than the hollow diameter was pushed into the hollow by the weight of the pedestal due to sliding on the inner surface of the hollow. It is considered that the catching of the lid by the angular edge was eliminated by the C-surface machining of the edge, making it easier to slide. Therefore, the insertion of the lid attached to the hollow can be shallow. The C-surface machining dimension has an effect at about 0.5 mm, and it is better if it is larger. Also, if it is changed to R-surface machining, although the processing becomes more advanced, it is even better.

[0020] Experiment 3 was conducted with the lid's outer diameter remaining at 27.5 mm, and its thickness set to approximately 20.0 mm, which is 1.1 times the cavity depth of 18.0 mm. When the base is lifted from a flat surface such as a shelf, the lid bulges out in a dome shape by the amount exceeding the depth of the cavity. This bulge has the effect of making the lid easier to grasp, facilitating attachment and removal, eliminating the need to insert two fingers into the cavity, and protecting the fingers by acting as a buffer between the edge of the cavity and the fingers. (Figure 3)a At this time, the size of the bulge is the amount of thickness that had contracted due to the weight of the base. When the base is placed on a flat surface, it is pushed in and sinks down to the bottom surface of the base. The appropriate thickness of the lid is 1.1 to 1.2 times the depth of the cavity. Note that if the outer diameter is too small, it will not be able to contact the inner surface of the cavity and will not have enough elastic support to hold the stored items. If it's too large, the lid and cavity won't slide smoothly, making it difficult to press the base down when placed on a flat surface.

[0021] To summarize the present invention, the first method involves chamfering or rounding the edges of a cylindrical cavity drilled in the base. This has the effect of preventing chafing if the back of a finger touches the edge of the cavity, and making it less likely to be scratched if a fingernail touches it. The space between the cavity and the lid becomes slippery, and when the base is placed on a flat surface, the weight of the base pushes the lid in. Therefore, the insertion of the lid into the cavity does not need to be deep. The chamfering dimension should be 0.5 mm or more, and a larger dimension is better. Rounding is even better.

[0022] The lid, made of sponge, is cylindrical in shape, with an outer diameter 1.1 to 1.2 times the diameter of the cavity at the base. The thickness is also 1.1 to 1.2 times the depth of the cavity; this is the second method. When the base is lifted off a flat surface such as a shelf, the lid bulges out in a dome shape. This bulge has the effect of making the lid easier to grasp and remove, eliminating the need to insert two fingers into the cavity, and protecting the fingers.

[0023] The drive components are housed in an invisible cavity at the bottom of the base. The first and second methods make the lid easy to grasp, facilitating installation and removal. Furthermore, the base of the gyro device is designed to provide double protection against injury and fingernail scratches, ensuring safe operation. [Examples]

[0024] Figure 1 shows an embodiment 1 of the present invention. When the gyro device is used as a decorative object to be placed on a shelf or the like, the base is made of metal and consists of a cylindrical cavity in the bottom and a cylindrical sponge lid to seal the cavity. The cylindrical cavity in the bottom of the base has an inner diameter of 25.0 mm and a depth of 18.0 mm. The outer dimensions, including height, width, and depth, should be approximately half or less of the main body.

[0025] The edges of the cylindrical cavity drilled in the base are chamfered or rounded. This is the primary method. This prevents chamfering if the back of your finger touches the edge of the cavity and makes it less likely to be scratched if your fingernail touches it. The space between the cavity and the lid becomes slippery, and when the base is placed on a flat surface, the weight of the base will push the lid in. Therefore, the insertion of the lid into the cavity does not need to be deep. The chamfered dimension should be 0.5 mm or more. Rounding is even better.

[0026] The lid, made of sponge, will be cylindrical in shape, with an outer diameter of approximately 28.0 mm, which is 1.1 to 1.2 times the diameter of the cavity at the base. Its thickness will also be approximately 20.0 mm, which is 1.1 to 1.2 times the depth of the cavity. This will be the second method. When the base is lifted off a flat surface such as a shelf, the lid will bulge out into a dome shape. This bulge has the effect of making the lid easier to grasp and remove, eliminating the need to insert two fingers into the cavity, and protecting the fingers by acting as a barrier between the edge of the cavity and the fingers.

[0027] The drive components are housed in an invisible cavity at the bottom of the base. The first and second methods facilitate the attachment and removal of the lid. Furthermore, the base of the gyro device provides double protection against injury and fingernail scratches, ensuring safe operation. [Examples]

[0028] Figure 2 shows an example of the application of the present invention to a spinning top. Some spinning tops do not have a base attached. It is recommended to attach one if you intend to use it as a decorative object on a shelf or the like. When spinning it as a top, place one side of the axle on the base and rotate it. When using it as a decorative object, tilt the main body and place the outer ring on the base. The top surface of the base has a recess for placing one side of the axle. Also, the main body and base are separate. Otherwise, it is the same as Example 1, in which the main body and base are integrated. [Industrial applicability]

[0029] The invention described in claim 1 of this invention is suitable for a base for decorative objects displayed on shelves, etc. Decorative objects often contain many parts that are used temporarily or small parts that are attached and detached. These are prone to getting lost and are a nuisance when placed near the decorative object. By providing a cavity in the bottom of the base and storing these parts there, they can be kept out of sight and their loss can be prevented. The cavity is sealed with a lid made of sponge material. Because it facilitates storage and retrieval and also helps prevent finger injuries, it can be used in a wide range of industries as a base for decorative objects displayed on shelves, etc. [Explanation of Symbols]
