2. Description of Related Art
People nowadays work very hard and thus seldom perceive soreness in the lower back, shoulders, and/or legs until they get off from work. The soreness triggers a desire to not only receive a soothing massage but also go home for rest as soon as possible. The best way to satisfy the two aforesaid needs simultaneously is to purchase a massage device for use at home, so as to receive a soothing massage at home in a relaxing manner. To this end, a wide variety of conventional massage devices are commercially available.
Conventional massagers are mostly massage chairs. However, massage chairs have their disadvantages as follows: too bulky to be storable indoors and movable freely to massage all parts of a user's body; and too pricy to be affordable. Furthermore, the conventional massagers fail to stay away from the spinal column and thus are ineffective in massaging synchronously the lumbar muscles which flank the spinal column Accordingly, there is still room for improvement of the conventional massagers.
It is an objective of the present invention to provide a massager with symmetric massaging structure, characterized in that: first and second massaging sets can operate in different modes, that is, the first and second massaging sets either knead the user's body in a fixed-point manner, or move laterally by moving synchronously toward each other or away from each other to thereby knead the user's body; after restoring its initial position, the first massaging set does not start to move together with the second massaging set until the second massaging set restores its initial position too, and, conversely, after restoring its initial position, the second massaging set does not start to move together with the first massaging set until the first massaging set restores its initial position too; and each round trip is accompanied by an instance of adjustment of electromechanical speed, such that the first and second massaging sets move synchronously.
In order to achieve the above and other objectives, the present invention provides a massager with symmetric massaging structure, comprising: first and second casing assemblies coupled to and flanked by the connection belts, respectively; first and second handles connected to free ends of the two connection belts, respectively; first and second movable sleeves, wherein the first and second casing assemblies are connected pivotally by the first and second movable sleeves, respectively, such that specific included angles between the first and second casing assemblies are adjustable so as for the first and second casing assemblies to be bent relative to each other; first and second power sources disposed in the first and second casing assemblies to drive the first and second transmission members to move, respectively; first and second massaging sets, wherein the first and second transmission members protrude from the first and second casing assemblies to connect with and drive the first and second massaging sets to move, respectively; first and second tooth-guiding groove screws, wherein the first and second transmission members drive the first and second tooth-guiding groove screws to advance in a direction of the first and second movable sleeves in a fixed-point manner, respectively; wherein first and second tooth-like keys enable the first and second movable sleeves to be engaged with circumferential tooth-guiding grooves of the first and second tooth-guiding groove screws, respectively; wherein the first and second tooth-guiding groove screws rotate to pull synchronously the first and second casing assemblies toward each other or away from each other, such that the first and second massaging sets knead the user's body in a fixed-point manner; wherein the user presses a reverse button to allow the first and second massaging sets to move toward each other and knead the user's body; wherein, after restoring its initial position, the first massaging set does not start to move together with the second massaging set but is idle until the second massaging set restores its initial position too, and, conversely, after restoring its initial position, the second massaging set does not start to move together with the first massaging set but is idle until the first massaging set restores its initial position too; wherein each round trip is accompanied by an instance of adjustment of electromechanical speed, until the first and second massaging sets move synchronously.
Objectives, features, and advantages of the present invention are hereunder illustrated with specific embodiments in conjunction with the accompanying drawings, in which:
The present invention provides a massager with symmetric massaging structure.
Referring to
The first and second casing assemblies 10a, 10b are coupled to and flanked by the connection belts 20a, 20b, respectively.
The first and second casing assemblies 10a, 10b are connected pivotally by the first and second movable sleeves 40a, 40b, respectively, such that specific included angles between the first and second casing assemblies 10a, 10b are adjustable so as for a user to bend the first and second casing assemblies 10a, 10b relative to each other at a point of pivotal connection.
The first and second casing assemblies 10a, 10b have therein first and second power sources 51a, 51b for driving the first and second transmission members 50a, 50b to move, respectively.
The first and second transmission members 50a, 50b are connected to the first and second massaging sets 60a, 60b positioned outside the first and second casing assemblies 10a, 10b, respectively, such that the first and second transmission members 50a, 50b drive the first and second massaging sets 60a, 60b to move, respectively.
The first and second transmission members 50a, 50b drive the first and second tooth-guiding groove screws 70a, 70b to advance in the direction of the first and second movable sleeves 40a, 40b in a fixed-point manner, respectively. First and second tooth-like keys 41a, 41b enable the first and second movable sleeves 40a, 40b to be engaged with circumferential tooth-guiding grooves 71a, 71b of the first and second tooth-guiding groove screws 70a, 70b, respectively; hence, the first and second tooth-guiding groove screws 70a, 70b rotate to pull synchronously the first and second casing assemblies 10a, 10b toward each other or away from each other. Hence, the first and second massaging sets 60a, 60b knead the user's body in a fixed-point manner and in an electrically controlled manner. Alternatively, the first and second massaging sets 60a, 60b are electrically controlled to move laterally by moving synchronously toward each other or away from each other to thereby knead the user's body. After restoring its initial position, the first massaging set 60a does not start to move together with the second massaging set 60b but stays idle until the second massaging set 60b restores its initial position too; conversely, after restoring its initial position, the second massaging set 60b does not start to move together with the first massaging set 60a but stays idle until the first massaging set 60a restores its initial position too. Each round trip is accompanied by an instance of adjustment of electromechanical speed of the first and second power sources 51a, 51b, until the first and second massaging sets 60a, 60b move synchronously.

It is only after the user has pressed and started the power button that the user can press a reverse button of the electrical control panel 80. As soon as the reverse button is pressed, the first and second massaging sets 60a, 60b knead reversely and restore their initial positions. After restoring its initial position, the first massaging set 60a does not start to move together with the second massaging set 60b but stays idle until the second massaging set 60b restores its initial position too; conversely, after restoring its initial position, the second massaging set 60b does not start to move together with the first massaging set 60a but stays idle until the first massaging set 60a restores its initial position too. That is to say, after both the first and second massaging sets 60a, 60b have restored their initial positions, the first and second massaging sets 60a, 60b begin to knead the user's body reversely and move laterally. Each round trip is accompanied by an instance of adjustment of electromechanical speed of the motors 511, until the first and second massaging sets 60a, 60b move synchronously. At this point in time, if the user presses the reverse button again, the first and second massaging sets 60a, 60b will begin to knead the user's body in a fixed-point manner. The aforesaid button-pressing instances can cycle.
Accordingly, the massager with symmetric massaging structure of the present invention is not only novel and thus meets the novelty requirement of an invention patent, but is also extensively innovative and thus meets the inventiveness requirement of an invention patent. Furthermore, the massager with symmetric massaging structure of the present invention manifests industrial applicability, as the massager with symmetric massaging structure of the present invention is advantageously characterized in that: the first and second massaging sets can operate in different modes, that is, the first and second massaging sets either knead the user's body in a fixed-point manner, or move laterally by moving synchronously toward each other or away from each other to thereby knead the user's body; after restoring its initial position, one said massaging set does not move together with the other massaging set until the other massaging set restores its initial position too, such that the first and second massaging sets move synchronously.
