[0057] The invention will be detailed by reference to FIG. 1 through FIG. 7. The present invention is basically about encircling a lamp bead with petal-shaped tabs that are attached to sliding arms, and having the sliding arms connected to sliding sleeves, so that a damper device or a power transmission device can drive the sliding sleeves to move and in turn open or close the petals.

Embodiment 1

[0058] To address the shortcomings of the prior art, the present invention provides a flower-structured, dynamic, decorative lamp 100. The flower-structured, dynamic, decorative lamp 100 comprises at least two layers of petal structures arranged as an inner layer and an outer layer, and at least one lamp bead. When the inner-layer petal structure is closed, the lamp bead is enclosed radically inside the inner-layer petal structure. The at least two inner-layer and outer-layer petal structures are mounted around a stem 107 via their respective sliding sleeves 136 in a manner that the petal structures are coaxial about an axis Z 130 and allowed to slide upward and downward. When the petal structures are assembled, the sliding sleeve 136 of the inner-layer petal structure is located above the sliding sleeve 136 of the outer-layer petal structure in a direction of the axis Z 130.

[0059] A petal posing mechanism 106 is mounted around the stem 107 coaxially with the respective sliding sleeves 136 of the two inner-layer and outer-layer petal structures about an axis Z 130 such that the petal posing mechanism 106 axially upward resists gravitation of the at least two inner-layer and outer-layer petal structures. Therein, the petal posing mechanism 106 changes a separation level of all petals hinged at the sliding sleeve 136 of at least the outer-layer petal structure by sliding along the stem 107 with respect to the sliding sleeve 136 of the outer-layer petal structure. Preferably, relative sliding between the petal posing mechanism 106 and the sliding sleeve 136 can be driven by a damper device or a power transmission device.

[0060] Preferably, the outer-layer petal structure is formed by connecting a plurality of first sliding arms 104 connected with first petal-shaped tabs 105 to one sliding sleeve 136, and the inner-layer petal structure is formed by connecting a plurality of second sliding arms 102 connected with second petal-shaped tabs 103 to the other sliding sleeve 136. The petal posing mechanism 106 is a hemispherical housing. The petal posing mechanism 106 has its periphery contacting a middle portion of each said first sliding arm 104. The petal posing mechanism 106 has its vertex provided with a through hole for enabling connection between the sliding sleeve 136 of the outer-layer petal structure and the damper device or a power transmission device that powers simulation of blooming dynamics of a real-world flower.

[0061] Preferably, the damper device is such configured to drive the two sliding sleeves 136 to move away from the petal posing mechanism 106 along the axis Z 130 in the process of simulation of a blooming flower.

[0062] Referring to FIG. 1, at least three sliding arms are spaced by an angle and they are hinged at the pivot section 124 of the sliding sleeve 136 through a restricting member. For the lamp to simulate a blooming flower, when the sliding rod 108 connected with the sliding sleeve 136 moves along its own axis, the included angle between each of the sliding arms and the petal posing mechanism 106 changes. The sliding rod 108 has its one end connected to the sleeving section 125 of the sliding sleeve 136, and has its opposite end connected to a damper device that drives the sliding rod 108 passing through the petal posing mechanism 106 to drive the sliding sleeves 136 to move.

[0063] Referring to FIG. 2, preferably, the sliding sleeve 136 at least comprises a sliding sleeve 136 connected to the outer-layer petal structure and sliding sleeve 136 connected to the inner-layer petal. The sliding sleeve 136 connected to the inner-layer petal structure and the sliding sleeve 136 connected to the outer-layer petal structure are connected. The sliding sleeve 136 connected to the outer-layer petal structure can be connected to the sliding rod 108. The sliding arm at least comprises a first sliding arm 104 hinged at the sliding sleeve 136 connected to the outer-layer petal structure and a second sliding arm 102 hinged at the sliding sleeve 136 connected to the inner-layer petal. In the process of simulation of a blooming flower, the first sliding arms 104 change the included angle they form with the petal posing mechanism 106 so that the restriction provided by the first petal-shaped tabs 105 to the second petal-shaped tabs 103 attached to the second sliding arms 102 changes.

[0064] Preferably, the petal posing mechanism 106 is connected to the damper device through the stem 107. The stem 107 defines a space for accommodating the sliding rod 108. The stem 107 remains connected with the damper device or the power transmission device when the damper device or the power transmission device drives the sliding rod 108 to move, so that relative displacement happens between the sliding rod 108 and the petal posing mechanism 106.

[0065] Referring to FIG. 2 and FIG. 3, the sliding sleeve 136 is formed by a sleeving section 125, a pivot section 124, and an upper connector 135 arranged along the axis Z 130. The pivot section 124 connects plural first sliding arms 104 or plural second sliding arms 102. The plural first sliding arms 104 or the plural second sliding arms 102 are connected to the pivot section 124, wherein the first sliding arm 102 or the second sliding arm 104 has a first sliding arm connector 134 or a second sliding arm connector 132 in the form of being arranged coplanarly and separated by an angle from each other to the pivot section 124 of the sliding sleeve 136 through a restricting member 137, so as to form the outer-layer petal structure or the inner-layer petal structure. The upper connector 135 of the sliding sleeve 136 in the inner-layer petal structure is for receiving the lamp bead 101, and the sleeving section 125 of the sliding sleeve 136 in the inner-layer petal structure is connected to the upper connector 135 of the sliding sleeve 136 in the outer-layer petal structure, so that the lamp bead 101, the outer-layer petal structure, and the inner-layer petal structure jointly form a flower-like structure. The sleeving section 125 of the sliding sleeve 136 in the outer-layer petal structure is for receiving the damper device or the power transmission device, so that the damper device or the power transmission device drives the sliding sleeve 136 to move along the axis Z 130. Preferably, the damper device is connected to the sleeving section 125 of the sliding sleeve 136 in the outer-layer petal structure through the sliding rod 108.

[0066] When the damper device drives the two sliding sleeves 136 to move along the axis Z 130, the first sliding arm 104 is hinged at one end of the pivot section 124, i.e., the first sliding arm connector 134, moves with the sliding sleeve 136, while the free end of the first sliding arm 104 move in a direction opposite to the sliding sleeve 136. Therefore, change of an included angle between each said first sliding arm 104 and the petal posing mechanism 106 in a plane defined by a contact point therebetween and the axis Z 130 and change of a position of each said first petal-shaped tab 105 connected with a respective said sliding arm 104 happen, and they can jointly allow the outer-layer petal structure to simulate opening and closing actions of outer-layer petals of a real-world flower.

[0067] Referring to FIG. 4, preferably, the damper device drives the sliding sleeve 136 in the outer-layer petal structure to move away from the petal posing mechanism 106 through the sliding rod 108, thereby simulating a blooming flower. Preferably, in the process of simulation of a blooming flower, the included angle between the first sliding arms 104 and the sliding sleeve 136 to which they are hinged increases so that the hinge point comes close to the periphery of the petal posing mechanism 106. Preferably, the first sliding arms 104 use their contact with the periphery of the petal posing mechanism 106 to resist the gravitational effects of the outer-layer petal structure itself, thereby preventing the outer-layer petal structure from over-dropping.

[0068] Preferably, the second sliding arms 102 can drop by gravity. Limited by the step provided on the sliding sleeve 136 to which they are hinged, the separation level between the second sliding arms 102 and the sliding sleeve 136 is smaller than 90 degrees.

[0069] Referring to FIG. 5, preferably, in the process of simulation of gathering of petals of a flower, the damper device drives the sliding sleeve 136 in the outer-layer petal structure to come close to the inner vertex of the petal posing mechanism 106 through the sliding rod 108, thereby simulating the closing action of a flower. The housing and the periphery of the petal posing mechanism 106 force the first sliding arms 104 to rotate about the hinge point between it and the sliding sleeve 136 to reduce the included angle between it and the sliding sleeve 136, thereby reducing the separation level of the outer-layer petal structure. Preferably, when the separation level of the outer-layer petal structure is reduced, the inner-layer petal structure is pressed by the outer-layer petal structure and therefore has its separation level reduced.

[0070] Referring to FIG. 6, preferably, in the process of simulation of closing of a flower, the first petal-shaped tabs 105 of the outer-layer petal structure are in contact with the second petal-shaped tabs 103 of the inner-layer petal structure. In the process where the housing and the periphery of the petal posing mechanism 106 force the first sliding arms 104 to rotate about the hinge point between it and the sliding sleeve 136 to reduce the included angle between it and the sliding sleeve 136, the first petal-shaped tabs 105 attached to the first sliding arms 104 come into contact with the second petal-shaped tabs 103 attached to the second sliding arms 102, and transfer the pushing force they receive from the housing and periphery of the petal posing mechanism 106 to the second petal-shaped tabs 103, thereby forcing the second sliding arms 102 to come close to the sliding sleeve of the inner-layer petal structure, and in turn reducing the separation level of the inner-layer petal structure.

[0071] Preferably, the second sliding arm 102 is hinged at one end of the pivot section 124. This makes the second sliding arm connector 132 move with the sliding sleeve 136. When the outer-layer petal structure simulates outer-layer petals of a flower to open and close, the sliding sleeve 136 in the inner-layer petal structure moves with the sliding sleeve 136 in the outer-layer petal structure.

[0072] Preferably, in the process where the damper device drives the sliding rod 108 to move, the first sliding arm 104 at least has an open position, an over-blooming position, and a closed position. Preferably, the flower-structured, dynamic, decorative lamp 100 of the present invention is made to simulate the whole process where a bud blooms into a flower. Preferably, when the flower-structured, dynamic, decorative lamp 100 of the present invention simulates a bud, the first sliding arm 104 is in its closed position. When the flower-structured, dynamic, decorative lamp 100 of the present invention simulates the fully bloomed flower, the first sliding arm 104 is in its over-blooming position. Preferably, in the process where the lamp simulates a flower from its bud state to its fully bloomed state, the first sliding arm 104 is in its open position.

[0073] Referring to FIG. 1, preferably, the damper device at least comprises a sliding shaft 114, a spring 116, and damping grease 115. Damping grease 115 applied to the surface of the sliding shaft 114 can retard the movement of the sliding shaft 114 when the spring 116 performs restorable deformation, so that the movement of the sliding rod 108 connected with the sliding shaft 114 is limited in speed.

[0074] Preferably, the damper device may be connected with the base 121 to support the flower-structured, dynamic, decorative lamp 100. The damper device and the sliding rod 108 are connected together and then enclosed in the casing 110. When the damper device and the base 121 are connected, a protuberance 111 formed on the casing 110 can fit in a recess 119 formed in the socket 120 of the base 121.

[0075] Preferably, when the protuberance 111 of the casing 110 fits in the recess 119 of the base 121, a tongue formed on the casing 110 is in contact with a spring sheet 118 installed in the socket 120 of the base 121 to form a feed path, so that the battery box 122 installed inside the base 121 can power the lamp bead 101 installed in the flower-simulating lamp. Preferably, a user may use a switch 123 connected with the battery box 122 to control power supply to the lamp bead 10.

[0076] Preferably, the spring 116 in the damper device is connected with an adjusting cap 117. When the damper device is enclosed in the casing 110, the spring 116, the adjusting cap 117, and the casing 110 jointly form a springiness adjusting mechanism for adjusting the initial spring force of the spring 116 in the damper device, thereby being adaptive to operating forces from different users.

[0077] Preferably, where a damper device is used to drive the sliding rod 108, the sliding rod 108 at its end close to the damper device is provided with a pressing lever 109 on which a user can exert a force, thereby make the spring 116 perform plastic deformation.

[0078] A user may exert a force on the pressing lever 109 to make the sliding rod 108 move away from the sliding sleeve 136 and in turn gather the first sliding arms 104 together. When the spring 116 restores from its elastic deformation, it drives the sliding rod 108 to move toward the sliding sleeve 136. With the effects of the damping grease 115, the sliding rod 108 moves toward the sliding sleeve 136 connected with the outer-layer petal structure slowly and steadily. In the process where the damper device drives the sliding rod 108 to move toward the sliding sleeve 136 connected with the outer-layer petal structure, the first sliding arms 104 move from the closed position to the open position and eventually to the over-blooming position. As a result of the change in position of the first sliding arms 104, the first petal-shaped tabs 105 attached to the first sliding arms 104 lose their restricting effects on the second petal-shaped tabs 103 attached to the second sliding arms 102, so that the second sliding arms 102 and the second petal-shaped tabs 103 attached thereto have displacement due to gravitation, thereby simulating the blooming process of a flower.

[0079] Preferably, when a user exerts a force on the pressing lever 109, the sliding rod 108 moves away from the sliding sleeve 136, so that first sliding arms 104 are gathered. The first petal-shaped tabs 105 attached to the first sliding arm 104 come into contact with the second petal-shaped tabs 103 attached to the second sliding arms 102 and force the second petal-shaped tabs 103 to get gathered, resembling the closing action of a flower.

Embodiment 2

[0080] The present embodiment provides further improvements to Embodiment 1, and all the details that have been discussed previously will not be repeated herein. Referring to FIG. 7, the present embodiment uses a power transmission device to drive the sliding rods 108.

[0081] Preferably, the power transmission device at least comprises an electric motor 128 and a transmission frame 129. The transmission frame 129 is connected to the lower base cover 127. The output shaft of the electric motor 128 is connected to the threaded bar 139. The threaded bar 139 is connected to the sliding nut support 138. The sliding rod 108 and the sliding nut support 138 are connected together to form a lifting structure, so that the sliding rod 108 is endowed with a lifting property. Preferably, the electric motor 128 may be a stepping motor, so that a user can conveniently adjust the rotational speed of the electric motor 128 and the initial postures of the petal-shaped tabs.

[0082] Preferably, the electric motor 129 is installed in the lower base cover 127. The electric motor 128 and the transmission frame 129 are connected together to form the power transmission device. The lower base cover 127 is combined with an upper base cover 126 so as to enclose the power transmission device therebetween and support the flower-shaped, dynamic, decorative lamp 100. The petal posing mechanism 106 is connected to the upper base cover 126 (the casing of the power transmission device) through the stem 107.

[0083] Preferably, in the present embodiment, after the sliding rod 108 is connected to the power transmission device, a user may control how fast the flower-simulating bloom process of the flower-structured, dynamic, decorative lamp 100 by adjusting the rotational speed of the electric motor. Preferably, the present embodiment uses the power transmission device to drive the flower-structured, dynamic, decorative lamp 100 to adjust the initial postures of the petal-shaped tabs freely. Additionally, when simulating a blooming flower, the present embodiment can provide different blooming speeds by adjusting the rotational speed of the electric motor 128.

[0084] Embodiment 3

[0085] The present embodiment provides further improvements to Embodiments 1 and 2, and all the details that have been discussed previously will not be repeated herein. Preferably, an electromagnetic levitation device is included to control the first sliding arms 104 and the second sliding arms 102. Preferably, the effects of electromagnetic levitation prevent the second petal-shaped tabs 103 attached to the second sliding arms 102 from posing unnaturally as they become over separated before the first petal-shaped tabs are fully separated and thus failing to simulate the full blooming process of a flower as a result of changing posture under the gravitational effects of the second sliding arms 102 and of the second petal-shaped tabs 103 as well as the restriction from the first petal-shaped tabs 105 attached to the first sliding arms 104.

[0086] Preferably, the petal posing mechanism 106 is connected to the damper device or the power transmission device through the stem 107. The stem 107 defines therein a space for accommodating the sliding rod 108. Throughout the process where the damper device or power transmission device drives the sliding rod 108 to move, the stem 107 remains connected with the damper device or power transmission device, so as to achieve relative displacement between the sliding rod 108 and the petal posing mechanism 106.

[0087] Preferably, when the sliding rod 108 comes close to the sliding sleeve 136 connected with the outer-layer petal structure, the first sliding arms 104 are switched to the separated state from the gathered state. The first petal-shaped tabs 105 attached to the first sliding arms 104 move with the first sliding arms 104, thereby making the outer-layer petal structure open. When the first petal-shaped tabs 105 start to simulate the opening action of the outer-layer petals of a flower, the first petal-shaped tabs 105 separate from the second petal-shaped tabs 103 attached to the second sliding arm 102, so that the second petal-shaped tabs 103 are released from restriction of the first petal-shaped tabs 105. When becoming independent of the first petal-shaped tabs 105, the second petal-shaped tabs 103 shift from the separated state to the gathered state due to the gravitation of the second sliding arms 102, thereby simulating the opening action of inner-layer petals of a flower.

[0088] Preferably, the blooming process of a flower is simulated by at least four successive states, namely (1) the outer-layer petal structure open and the inner-layer petal structure closed, (2) both the outer-layer petal structure and the inner-layer petal structure open, (3) the outer-layer petal structure over open and the inner-layer petal structure normally open, and (4) both the outer-layer petal structure and the inner-layer petal structure over open. Preferably, the four states represent the about-to-bloom state, the early blooming state, the fully blooming state, and the over blooming state of a flower, respectively. Preferably, the present invention uses an electromagnetic levitation device to control the first sliding arms 104 and the second sliding arms 102 to simulate different blooming states of a flower.

[0089] Preferably, the blooming state of a flower is implemented as below. The electromagnetic levitation device sizes a magnetic force it applies to the second sliding arms 102 according to the position of the first sliding arms 104, so as to control the states of the second petal-shaped tabs 103, thereby simulating different blooming states of a flower.

[0090] Preferably, when simulating the about-to-bloom state of a flower, that is, when the present invention simulates the state that the outer-layer petal structure open and the inner-layer petal structure closed, the first sliding arms 104 shift to the open position from the closed position.

[0091] When the first sliding arms 104 are in their open position, the electromagnetic levitation device is in its first state in which it holds the second sliding arms 102 still. In its first state, the electromagnetic levitation device generates a levitation force that is sufficient to cancel the acting force that makes the second sliding arms 102 and the second petal-shaped tabs 103 enter the open state from the closed state. Preferably, the acting force that makes the second sliding arms 102 and the second petal-shaped tabs 103 enter the open state from the closed state or makes the second sliding arms 102 and the second petal-shaped tab 103 move is the component force of its gravitation in its moving direction.

[0092] Preferably, when simulating the early blooming state of a flower, that is, when the present invention simulates the state that both the outer-layer petal structure and the inner-layer petal structure open, the first sliding arms 104 are in their open position, and the electromagnetic levitation device is in its second state. Preferably, in its second state, the electromagnetic levitation device first reduces the levitation force it generates so that the levitation force is smaller than the acting force that makes the second sliding arms 102 and the second petal-shaped tabs 103 enter the open state from the closed state, thereby allowing the second petal-shaped tabs 103 to enter the open state from the closed state. Preferably, before the second petal-shaped tabs 103 enter the open state, the electromagnetic levitation device increases the levitation force it generates to cancel the acting force that makes the second sliding arms 102 and the second petal-shaped tabs 103 move, and when the second petal-shaped tabs 103 enter the open state, the electromagnetic levitation device increases the levitation force it generates so that the second petal-shaped tabs 103 can stop at the open position.

[0093] Preferably, when simulating a fully blooming state of a flower, that is, when the present invention simulates the state that the outer-layer petal structure over open and the inner-layer petal structure normally open, the first sliding arms 104 shift from the open position to the over-blooming position. For the disclosed lamp to simulate a fully blooming flower, the electromagnetic levitation device is in its third state. At this time, the levitation force generated by the electromagnetic levitation device can cancel the acting force that makes the second sliding arms 102 and the second petal-shaped tabs 103 move, thereby allowing the second petal-shaped tabs 103 to keep the open state.

[0094] Preferably, when simulating the over blooming state of a flower, that is, when the present invention simulates the state that both the outer-layer petal structure and the inner-layer petal structure over open, the first sliding arms 104 are in the over-blooming position. At this time, the electromagnetic levitation device is in its fourth state. Preferably, in its fourth state, the electromagnetic levitation device generates a reduced levitation force, so that the second petal-shaped tabs 103 enter the over-open state form the open state.

[0095] Preferably, the electromagnetic levitation device adjusts the levitation force by detecting the position of the first sliding arms 104, so as to control the position of the second petal-shaped tabs 103, thereby simulating different blooming states of a flower.
