The present invention relates to a switch that can be used to detect motion in a particular direction. In particular, the present invention relates to a switch that can be used to detect motion of an object in a particular direction or directions. In one embodiment, the object can be a toy and the switch can be disposed within the toy.
There are many types of switches that can be used to detect motion of an object. Typically, a switch is connected to an electronic system that is configured to generate an output in response to the closing of the switch. In some objects, it is desirable to detect when the object is moving in a particular direction but not another direction. For example, it may be desirable to detect when an object is moving in a vertical direction and not a horizontal direction. However, conventional switches are limited in their ability to detect motion in a particular direction.
Therefore, a need exists for a switch that can be used to detect motion of an object in a particular direction or directions. In addition, the need exists for a switch that performs that function while being compact and easy to use.
The present invention relates to a switch or switch mechanism that can be coupled to an object and used to detect motion of the object. When the object moves, a component of the switch moves as well, thereby facilitating the detection of motion. Depending on the orientation of the switch, movement or motion in a particular direction or directions can be detected.
In one embodiment, the switch that has a pair of contacts and a conductive mechanism that is disposed so that it can engage the contacts. Each of the contacts and the conductive mechanism is either made of a conductive material or has a conductive layer of material disposed thereon. In one embodiment, each contact is configured to be connected to an electronic system, such as by wiring. In a normal, stationary position, the conductive mechanism engages one of the contacts but not the other contact. When the switch is moved, such as by moving the object to which the switch is coupled, the conductive mechanism remains engaged with the first contact and moves into and out of engagement with the second contact. When the conductive mechanism engages both contacts, the switch completes a full circuit and a signal can be generated as current passes through the switch.
In one embodiment, the conductive mechanism includes a resilient portion and a contact portion. The resilient portion is configured to support the contact portion. When the object, and as a result, the switch, move, the weight of the contact portion imparts movement to the resilient portion. Thus, the resilient portion remains engaged with one contact and the contact portion selectively engages the other contact in response to motion of the object and the switch.
In one embodiment, a switch for detecting motion in an object includes a first contact connected to an electronic system, a second contact connected to the electronic system, and a conductive mechanism engaged with the first contact and selectively engageable with the second contact in response to movement of the object along a first direction and at a particular frequency and not to movement of the object along a second direction or at a frequency less than the particular frequency. The conductive mechanism includes a resilient portion and a contact portion, the resilient portion supporting the contact portion for movement. Movement of the object along the first direction at the particular frequency moves the contact portion into and out of engagement with the second contact. In addition, movement of the object in the second direction or at a frequency less than the particular frequency does not result in the contact portion engaging the second contact. In one implementation, the resilient portion is a coiled spring.
In one embodiment, a bouncing toy includes a base, a support coupled to the base and being movable relative to the base, a body coupled to the support and supported for movement relative to the base in a first direction and in a second direction different than the first direction, the body including a riding surface on which a child can sit, and an electronic system including an output device and a motion switch, the motion switch being coupled to one of the body or the support, the motion switch being closed in response to movement of the body in the first direction and not being closed in response to movement of the body in the second direction, the output device generating an output in response to the closing of the motion switch.
In alternative embodiments, the motion switch includes a first contact and a second contact, each of the first contact and the second contact being connected to the electronic system, the motion switch also including a conductive mechanism continuously engaged with the first contact and selectively engageable with the second contact in response to movement of the object in the first direction and not to movement of the object in the second direction. In other embodiments, movement of the body in the first direction moves the conductive mechanism into and out of engagement with the second contact. In addition, movement of the body portion in the second direction does not result in the conductive mechanism engaging the second contact.
In some embodiments, the resilient portion has a natural frequency characteristic and the conductive portion engages the second contact when the body moves at a frequency substantially the same as the natural frequency of the resilient portion. Depending on the orientation of the toy, the first direction is substantially vertical and the second direction is substantially horizontal or rotational.
In another embodiment, the switch includes a container having a wall defining an interior region, the first contact being located at one end of the container and the second contact being located at an opposite end of the container, the resilient portion and the conductive portion being located in the interior region, the conductive portion being selectively engageable with the second contact. The resilient portion defines a longitudinal axis, and the first direction is substantially aligned with the longitudinal axis. The container has a length and the resilient portion has an unbiased length, the unbiased length of the resilient portion being greater than the length of the container. The resilient portion is compressed when the conductive portion is engaged with the resilient portion, the resilient portion when compressed having a length less than the length of the container.
In another embodiment, a toy has a body including a first end and a second end opposite the first end, the body defining a longitudinal axis, the body being movable in a first direction and in a second direction by a user, and a motion switch coupled to the body, the motion switch having a primary axis along which a component of the motion switch can move, the primary axis being substantially aligned with the longitudinal axis of the body, the motion switch being closed in response to movement of the body along the first direction and not being closed in response to movement of the body along the second direction. The motion of the body in the first direction is a swinging motion within a plane and the motion of the body in the second direction is not along the plane.

For example, the switch can be used to detect motion of the object in a first direction and not motion of the object in a second direction, depending on the orientation of the switch. The switch may include a conductive mechanism that selectively engages a contact in response to movement along a first direction and not to movement along a second direction.

As illustrated, the switch portion 20 includes contacts 22 and 24 and a conductive mechanism 26. The contacts 22 and 24 are spaced apart from each other. In one implementation, the conductive mechanism 26 is in engagement with contact 24 and moveable into engagement with contact 22 (as represented by the dashed line). As the body 12 moves along the direction of arrow “A,” the conductive mechanism 26 intermittently engages contact 22 during such movement. As the body 12 moves along the direction of arrow “B,” the conductive mechanism 26 does not engage contact 22.
Contact 22 is made of a conductive material and has a connection 28 that can be connected to an electronic system by wiring or other conductive materials. Similarly, contact 24 is made of a conductive material and has a connection 30 that can be connected to wiring or other conductive material as well. Since the conductive mechanism 26 remains in contact and engagement with contact 24, a full circuit is formed when the conductive mechanism 26 engages contact 22. The engagement of conductive mechanism 26 with contact 22 closes the switch or switch portion 20 and a signal is generated, indicating that the switch 20 is closed.
The conductive mechanism 26 can move along any direction. Therefore, when the conductive mechanism 26 moves along the direction of arrow “A,” the conductive mechanism 26 moves into and out of engagement with contact 22, which causes the switch 20 to open and close. When the conductive mechanism 26 moves along the direction of arrow “B,” the conductive mechanism 26 does not engage the contact 22, and the switch 20 does not close.

The switch 50 includes a conductive mechanism 56 that has a resilient portion 58 and a contact portion 60. The resilient portion 58 is configured to support the contact portion 60 for movement. In one embodiment, the resilient portion 58 and the contact portion 60 are each made of a conductive material so the switch 50 is “closed” when the contact portion 60 moves into engagement with contact 52. The resilient portion 58 can have resilient properties such that it supports the contact portion 60 for movement along any direction. In one implementation, the resilient portion can be a spring or spring-like member that is placed in contact with contact 54. When contact portion 60 moves along the direction of arrow “C” and engages contact 52, the circuit or switch 50 is closed upon such engagement. However, if the contact portion 60 moves along the direction of arrow “D,” contact portion 60 does not engage contact 52 and the switch 50 does not close.

In this embodiment, the switch 100 includes a resilient member or portion 260 and a conductive or contact member 280. The resilient member 260 is a spring that supports the conductive member 280 for movement. In particular, the conductive member 280 is supported for movement by the resilient member 260 along the direction of arrow “F.” The resilient member 260 has ends 262 and 264 that are disposed proximate to end portions 130 and 160, respectively. The switch 100 includes a primary axis 125 as shown in

Now the particular features of the end portion 160 that are used to mount the contact 200 to the end portion 160 are described. The rim 172 includes several depending projections 180, 182, and 184 that are spaced around the length of the rim 172. In various embodiments, different quantities of projections can be provided on the end portion 160. As shown in
While the foregoing description relates to the end portion 160, end portion 130 has substantially the same structure with the exception of guide 190. End portions 130 and 160 are made of a non-conductive material, such as a molded plastic, and guide 190 can be formed integrally with the remainder of end portion 160. In other embodiments, the size and shape of the guide 190 can vary as well as the manner in which the guide 190 is formed with the end portion 160.

The container 116 and accordingly, the switch 100, can be moved randomly in space in any combination of directions. For example, the container 116 can be moved in any combination of up-and-down directions, side-to-side directions, and front-to-back directions, which can correspond to various planes, such as a horizontal plane as well as different vertically oriented planes. In addition, the container 116 can be moved in different rotational directions. Although all of those movements are possible, the container 116 can be used to detect motion in a particular direction. In one embodiment, the desired direction of motion to be detected is along the primary axis of the switch 100.

The support 340 is an elongate member that has resilient properties and a longitudinal axis 342. In one embodiment, the support 340 is a resilient member such as a spring. An upper end of the support 340 can be moved relative to a lower end of the support 340, thereby permitting the support 340 to flex and bend in any direction relative to the base 330. The object 300 is connected to the support 340 and therefore, the object 300 moves in the same direction as the upper end of the support 340. For example, the support 340 can lengthen and shorten as a child bounces on the object 300. Accordingly, the body 310 can move from an initial, unbiased position 320 to a lower position 322 (shown in phantom). In addition, the child can rock forward and backward on the object 300, and the body 310 can move to a forward position 324. Further, as shown in
As illustrated in
While the object may have numerous types and directions of movement, detection of movement of the object in a particular direction or directions may be desired. In one example, detection of movement of the object 300 along an upward direction and downward direction is desired and not movement in any of the other directions.
Movement of the object 300 upwardly and downwardly can be detected by using the switch 100. In
Referring to
The switch 100 can be located at any location on the body 310, including being mounted internally or externally. The particular motion detected is determined by the orientation of the switch 100. In an alternative embodiment of the object 300, two switches 100 can be provided. In this embodiment, one switch 100 can be located so that its axis is aligned with the directions of arrows “K” and “L” in
The present invention also contemplates another method or manner of detecting the motion of an object. The motion of an object is to be detected along a particular direction if the motion was oscillatory in nature and within a particular frequency range. In this case, motion of an object, such as a child's toy that can be bounced up and down, is to be detected when the object is being played with in a particular manner. For example, an object such as the bouncing object 300 described previously can be used by a child to move in a variety of directions. The object 300 can be configured so that when a child is bouncing on the object 300 with a particular intent and at a particular level of energy or effort, a switch associated with the object 300 is closed and one or more audible and/or visual outputs can be generated. As described in greater detail below, the particular play by the child to be detected can be determined by using a switch such as switch 100 that has a primary or detecting direction and a resilient or biasing member such as a spring therein.
In this particular detecting method, the movement of an object, such as object 300, at particular speed and in a particular direction will result in the closing of a switch associated with the object and accordingly, the detection of the motion of the object. Each spring or spring system has its own natural frequency, which, when matched by a vibration frequency, will resonate. The switch 100 includes a biasing member or spring 260 that has a natural frequency that is determined by various characteristics of the spring 260, including its thickness, length, and material. As the flexibility of a spring increases (such as due to its thickness and/or material changing), its natural frequency lowers. Alternatively, the more rigid that a spring is, the natural frequency is higher. Alternatively, the addition of a weight or mass, such as conductive member 280, to a spring lowers the resonance frequency of the spring 260. In one embodiment of the invention, the natural frequency of the spring 260 is approximately 3 Hz. In other embodiments, the natural frequency can vary and can be greater or less than 3 Hz as desired. The spring 260 that is used in the switch 100 can be selected so that its natural frequency closely matches the natural frequency of the object 300 whose motion is being detected.
In this embodiment, the detection of movement occurs if the object 300 is moved at the desired speed and along the desired direction as determined by the spring 260 and the conductive member 280 that are used in the switch 100. The spring 260 is mounted between two contacts 200 and 240 in the switch 100. The spring 260 continuously engages contact 200 and the conductive member 280 that is disposed on the other end of the spring 260 is located so that it can engage and disengage from contact 240 as the moving end of the spring 260 oscillates with the conductive member 280.
Thus, when the object 300 is moved along the primary or longitudinal direction of the spring 260 and at a frequency very close to the natural frequency of the spring 260, the conductive member 280 coupled to the spring 260 will move with a frequency determined in part by the mass of the conductive member 280 and the characteristics of the spring 260. When the frequency of the movement of the conductive member 280 and the spring 260 is at or near the natural frequency of the spring 260, the movement of the object will have a frequency that will result in the closing of the switch 100. The result is that the conductive member 280 moves into and out of engagement with the contact 240 of the switch 100 one or more times, depending on how long the object 300 is moved in that oscillatory manner.
If the motion of the object 300 is either too fast or too slow, the switch 100 is not closed. If the object 300 is moved only once, the switch 100 is not closed. Accordingly, motion of an object, such as a child bouncing or moving the object, in the desired range of speed and in an oscillatory manner will result in the switch 100 closing and the generation of an output, such as a visual output or an audible output, as a reward. Thus, in this embodiment, the conductive member 280 does not engage contact 240 to close the switch 100 unless the object 300 is moved at the proper speed and direction in the proper manner.

In this embodiment, the object 400 includes a body 410 with a proximal end 412 and a distal end 414. Referring to
A switch 100 can be coupled to the body 410, either internally or externally, and oriented so that the switch 100 detects the desired motion of the object 400. As shown in
The switch 100 is oriented so that the primary or detecting axis 125 of the switch 100 is aligned with an axis 415 of the object 400. While object 400 is in position 402, the switch 100 is oriented such that the conductive member 280 can move along the direction “W” and engage the contact of cap 130 to close the switch 100, if the proper force is applied to the conductive member 280. As the object 400 moves along the direction of arrow “V,” a centrifugal force acts on the conductive member 280, thereby forcing the conductive member 280 toward the distal end 414 of the body 410 and into engagement with the contact on the cap 130 (see the orientation of the switch 100 and movement along the direction of arrow “X” for object position 404). A proper swinging motion along arrow “V,” such as a horizontal motion, can result in conductive member 280 moving and the switch 100 being closed.

The switch 100 can be disposed within a cavity or receptacle formed in the club head 512. In other embodiments, the location of the switch 100 relative to the shaft 510 and the club head 512 can vary. In other embodiments, there can be two switches coupled to the object 500. One switch can be located within the shaft 510 and one switch can be located within the club head 512. In that implementation, an output is generated only when the switch in the shaft and the switch in the club head are both closed. Further, in any of the previous embodiments of objects that are moved, two or more switches can be included with the object to detect motion in multiple directions. Depending on the particular switch that is closed, the output that is generated will vary.
In different embodiments, the orientation of the switch and its movable components can vary as desired. In alternative embodiments, the shape and configuration of the contacts can vary. In addition, the manner in which the contacts are coupled to the end portions can vary, including the quantity of notches and projections that are used.
