The present invention relates to a switch, and in particular a multidirectional switch that detects motion in a first direction upon application of a first force and motion in a second direction upon application of a second force.
Various multi-sensor arrangements for detecting motion in two or directions are known. Such conventional arrangements typically provide for a plurality of sensor mechanisms, each of which detects motion along a linear axis. Other arrangements provide for multiple sensors which then extrapolate additional directional movement based on relatively complex processing algorithms.
There is a need for a multidirectional switch having a relatively simple configuration, that is inexpensive to manufacture, and that well suited to be incorporated into children's toys.
The present invention relates to a multidirectional switch. A support member is coupled to a base and extending outwardly from an upper surface of the base. A resilient member has a first end coupled to the support member and a distal second end spaced from the upper surface. A weight is coupled to the distal second end of the resilient member, and is spaced from the upper surface of the base. A first contact is coupled to the base and extends outwardly from the upper surface. A second contact is coupled to the base and extends outwardly from the upper surface. The weight is biased toward a neutral position spaced from the first contact and the second contact. The weight is movable toward and contacts the first contact when a first force is applied to the base. The first force extends the resilient member in a first direction. The weight is movable toward and contacts the second contact when a second force is applied to the base. The second force extends the resilient member in a second direction different than the first direction.
The present invention also relates to a multidirectional switch including a housing having opposing end walls and a sidewall extending between the opposing end walls. The housing defines a cavity. A weight is disposed within the cavity and coupled to one of the end walls via a resilient member. A first contact is coupled to the other end wall. The weight is movable toward and contacts the first contact when a first force is applied to the housing, which deforms the resilient member in a first direction. A second contact is coupled to the sidewall. The weight is movable toward and contacts the second contact when a second force is applied to the housing, which deforms the resilient member in a second direction different than the first direction.
In one embodiment, the second direction is substantially perpendicular to the first direction. In other embodiments, the second direction is angularly disposed relative to the first direction. In one embodiment, the first force is substantially equal to the second force. In other embodiments, the first force differs from the second force.
In one embodiment, the switch includes a brace adjacent a portion of the resilient member. In one implementation, the brace is intermediate the sidewall and a portion of the resilient member. The brace limits lateral movement of the portion of the resilient member toward the sidewall to a predetermined range of motion upon application of the second force.
In one embodiment, the housing sidewall includes a first side section and a second side section. The second contact is coupled to the first side section. A third contact is coupled to the second side section. The weight is movable toward and contacts the third contact when a third force is applied to the housing. The third force deforms the resilient member in a third direction different than the first and second directions. In some embodiments, the third force is substantially equal to the second force. In other embodiments, the third direction is substantially opposite to the second direction.
In one embodiment, the first, second and/or third contacts are electrically coupled to a sensory output mechanism. The sensory output mechanism triggers a first output when the weight contacts the first contact, triggers a second output when the weight contacts the second contact, and triggers a third output when the weight contacts the third contact.
The present invention also relates to a movement detecting toy device. The toy device includes a support body configured to be attached to or held by a user. A housing is coupled to the support body. The housing includes opposing end walls and a sidewall, and defines a cavity. A weight is disposed within the cavity and coupled to one of the end walls via a resilient member. A first contact is coupled to the other end wall. The weight is movable toward and contacts the first contact when a first force is applied to the housing, which deforms the resilient member in a first direction. A second contact is coupled to the sidewall. The weight is movable toward and contacts the second contact when a second force is applied to the housing, which deforms the resilient member in a second direction different than the first direction.
In one embodiment, the housing is configured to be coupled to an article that can be worn by a user. Alternatively, the support body is configured to be worn on a hand of the user. In addition, the device includes an output generating system that generates an output in response to the engagement of the weight with one of the first contact or the second contact.

The force required to deform the resilient member 16 in direction D1 a distance sufficient to contact the first contact 24, or to deform the resilient member 16 in direction D2 a distance sufficient to contact the second contact 26 (and thereby closing the switch S1), depends in part on the configuration and material properties of the resilient member 16. For example, the resiliency and distance the resilient member 16 deforms in a given direction may be defined by its overall size and configuration, as well as the material from which it is formed. In addition, force requirements for closing the switch S1 are also partially dependent on the spacing between the weight 22 and the first contact 24 when the weight 22 is in its neutral position N, and the spacing between the weight 22 and the second contact 26. Further, force requirements for closing the switch S1 are partially dependent on the mass and weight of the weight 22. By adjusting one or more of these characteristics, the force requirements for closing the switch S1 may be selectively tuned. For example, the mass of weight 22 may be increased or decreased in order to adjust forward sensitivity for closing the first contact 24, or side-to-side sensitivity for closing the second contact 26.

In one embodiment, the second and third contacts 26, 28 are arranged on the base 10 so that direction D2 is substantially opposite to direction D3. Further, the second and third contact 26, 28 may be substantially equally spaced from the weight 22 when the weight 22 is in its neutral position N. In other embodiments, the second and third contacts 26, 28 are differently spaced from the weight 22 when the weight 22 is in its neutral position N.
The first contact 24 may be arranged on the base 10 so that direction D1 is substantially perpendicular to direction D2 and/or direction D3. Alternatively, the first contact 24, the second contact 26 and/or the third contact 28 may be arranged so that the direction D1 is angularly disposed relative to direction D2 and/or direction D3.
A multidirectional switch S2 according to another embodiment is illustrated in
A first contact 116 is coupled to end wall 104, a second contact 118 is coupled to side section 106, and a third contact 120 is coupled to side section 108. The resilient member 114 biases the weight 112 toward a neutral position N between the first, second and third contacts 116, 118, 120 (such as shown in
The weight 112 is movable toward and contacts the first contact 116 when a sufficient force F1 is applied to the housing 100 that deforms the resilient member 114 in a direction D1 coaxial with or parallel to the longitudinal axis L (such as shown in
In one embodiment, the force F1 required to linearly expand the resilient member 114 so that the weight 112 contacts the first contact 116 is greater than the force F2 required to laterally deform the resilient member 114 toward the side section 106 and against the second contact 118. Further, in some embodiments force F2 is substantially equal to force F3. Accordingly, force F1 may also be greater than force F3 required to laterally deform the resilient member 114 toward the side section 108 and against the third contact 120.
In one embodiment, the resilient member 114 has an elongate configuration and is formed from a material that is linearly extendable in a direction parallel to or coaxial with the longitudinal axis L of the resilient member 114 (e.g. direction D1) by a predetermined distance upon exertion of a given force (e.g. force F1). For example, in one embodiment the resilient member 114 is a coil spring. The resilient member 114 is laterally extendable in a direction away from or angular to the longitudinal axis of the resilient member 114 (e.g. direction D2 or direction D3) by a predetermined distance upon exertion of a given force (e.g. force F2 or force F3).
In some embodiments, the resilient member 114 has a substantially uniform diameter throughout its length. In other embodiments, its diameter varies or tapers inwardly from end wall 102 to weight 112. A multidirectional switch S3 including a resilient member 200 according to an alternative embodiment is illustrated in
The resilient member 200 has an elongate configuration including a first portion 202 having a first diameter x1 and a second portion 204 having a second diameter x2 differing from the first diameter x1. In one embodiment, the first diameter x1 is greater than the second diameter x2, and a greater force is required to extend or and/or deform the first portion 202 compared to the force required to extend and/or deform the second portion 204. The force required to extend the resilient member a sufficient distance so that the weight 112 contacts an associated one of the first, second or third contacts 116, 118, 120 may be determined by selecting and/or adjusting the length ratio of the first portion 202 to the second portion 204. The overall length of the resilient member 200 and its material properties also partially determine the force required to close the first, second or third contacts 116, 118, 120 via contact by the weight 112. In one embodiment, the resilient member 200 is a coil spring having sections of varying diameter, or alternatively two or more coil springs of varying diameter that are coupled together.

The specific configuration of braces 300, 302 and their positions relative to side portions 206, 208 may vary depending on the lateral range of motion in direction D2 or D3 desired. In one embodiment, braces 300, 302 have a generally post-like or rectangular configuration. The position of the braces 300, 302 relative to the weight 112 partially determines the amount of force F2, F3 required to move the weight 112 against the first contact 116 and/or the second contact 118. The braces 300, 302 act as fulcrums around or against which the resilient member 200 pivots and extends in direction D2 or direction D3, respectively. Generally, the closer the braces 300, 302 are positioned to the weight 112, the greater the amount of force required to laterally move the weight 112 against the first or second contacts 116, 118.
Referring to
In alternative embodiments, other movement limiting structures may be employed for limiting or controlling the lateral movement of the resilient member 200 toward side section 106A and/or side section 108A. In addition or alternative to a post-like structure, the braces or movement limiting structure(s) may be configured as one or more rings extending around the resilient member 200. Alternatively, the movement limiting structure(s) may be configured as one or more ribs adjacent portions of the resilient member 200. Thus, various structures may be employed for constraining and/or controlling side-to-side motion of the resilient member 200 against laterally directed forces (relative to the longitudinal axis L of the resilient member 200).

The switches disclosed herein are relatively simply in construction, and relatively inexpensive to manufacture. Moreover, the simple design includes substantially fewer parts compared to conventional multidirectional switch arrangements. As such, the possibility of damage is minimized. The rugged switches of the present invention are particularly well suited for use in children's toys, which are often subject to substantial abuse during play.
One or more of the disclosed switches (S1, S2 or S3) may be incorporated into a variety of toys which include sensory output triggered by motion of the toy. Exemplary toys according to embodiments of the present invention include a support body, a switch (S1, S2 or S3) coupled to the support body, and a sensory output mechanism (400) coupled to the support body and electrically coupled to the switch (S1, S2 or S3). Movement of the support body triggers one or more contacts in the switch and triggers a sensory output as described above.
An exemplary toy 500 including a multidirectional switch according to an embodiment of the present invention is illustrated in
The toy 500 detects via switch S1 (or S2 or S3) a forward thrusting or punching motion by a user 1000 in a forward direction, and/or retracting motion in a backward direction, as shown in
The support body 502 moves in a given direction (e.g. direction D4, D5, D6 or D7) until the user stops motion of his or her hand or wrist, such as when the user's arm is fully extended in the punching motion. The momentum created during the forward, side-to-side, up and down, etc. motion of the user's hand exerts a force upon the weight 112 within the switch S1 (or S2 or S3) as the motion of the toy 500 decelerates or stops. A sufficient force F1 (as determined by the properties of the resilient member and/or the weight, spacing between the weight and contacts, and/or position and configuration of braces, ramps or other movement limiting structures) causes the weight 112 to contact a corresponding contact, thereby closing the switch S1 (or S2 or S3). A signal is then communicated to the sensory output mechanism 400A, which triggers an audio output, such as a ‘striking’ sound effect or a voice clip. Audio output may also be triggered via activation of an actuator button 510 operably associated with the sensory output mechanism 400A.
In one embodiment, the switch S1 (or S2 or S3) of toy 500 is configured so that a larger linear force is required to close the first contact 116, compared to a smaller side-to-side force required to close either the second or third contacts 118, 120. For example, the first contact 116 is contacted and closed by the weight 112 by a force F1 of more than three gravities. The second and third contacts 118, 120 are contacted and closed by the weight 112 by a force F2 and/or F3 of less than two gravities.
In one embodiment, each output associated with the closing of the first, second, and third contacts 116, 118, 120 in the toy 500 is different. In other embodiments, one of a plurality of audio outputs is associated with the closing of each of the first, second, and third contacts 116, 118, 120. For example, a first closing of the first contact 116 may trigger the generation of a first audio output; the subsequent closing of the first contact 116 may trigger the generation of a second audio output; the next closing of the first contact 116 may trigger the generation of a third audio output, etc. Alternatively, several audio outputs may be associated with the closing of the first contact 116, and one of the outputs is randomly selected and output via mechanism 400A. The second and third contacts 118, 120 may be similarly configured, and include more or fewer audio outputs.
In one embodiment, the specific sound effects output by the sensory output mechanism 400A relate to a particular theme. For example, the particular theme may be associated with wrestling, including punching sound effects and voice clips of various wrestling characters. Alternatively, the sound effects may be associated with an underwater theme including bubbling and splashing noises, or a space theme including blaster gun or rocket launch noises. Further, the toy 500 may include other sensory output, such as lights, tactile stimuli such as vibrations, etc.
Another exemplary toy 600 including a multidirectional switch according to an embodiment of the present invention is illustrated in
The toy 600 detects via switch S1 (or S2 or S3) motion of the toy 600, such as when a user swings the racket in a forward, back or side-to-side motion, as described above. A signal is then communicated to the sensory output mechanism 400B, which triggers an audio output, such as a ‘whooshing’ sound, a racquet strike sound, or a voice clip (e.g. “Beat That,” “Game Point,” etc.). Alternatively or in addition, the sensory output mechanism 400B may trigger a tactile output, such as a vibration device 606 disposed within a correspondingly configured cavity in the handle portion 602. Alternatively or additionally, the sensory output mechanism 400B may trigger a visual output, such as lights 608 disposed along a periphery of the hoop portion 604.
The wrist toy 500 and racquet toy 600 are exemplary only. The switch of the present invention may be incorporated into a variety of differently configured toy devices, including but not limited to other sports equipment such as bats or golf clubs, other wearable devices such as boots or helmets, toy vehicles, etc. Moreover, the switch may include fewer than three contacts, or more than three contacts, as desired and pursuant to application requirements. Further, two or more of the switches of the present invention may be incorporated into a support body.
Therefore, although the disclosed inventions are illustrated and described herein as embodied in one or more specific examples, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the scope of the inventions and within the scope and range of equivalents of the claims. Further, various features from one of the embodiments may be incorporated into another of the embodiments. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure as set forth in the following claims.
