Referring to fig. 1-3, fig. 1 illustrates a perspective view of a security device 10 according to an embodiment of the present application, fig. 2 illustrates a top view of the security device 10 shown in fig. 1, and fig. 3 illustrates a side view of the security device 10 shown in fig. 1.

In some embodiments, the security device 10 may be a unitary structure. The security device 10 may be made of, for example, plastic, silicone, etc. Alternatively, the security device 10 is made of polyethylene plastic. Alternatively, the security device 10 may be made of plastic with glass frit added to enhance the fire retardant effect of the security device 10. In some embodiments, the security device 10 may be integrally formed, such as by injection molding, extrusion, and the like.

In some embodiments, the security device 10 may have at least one wire embedded therein. This may enhance the compressive strength of the security device 10 such that the security device 10 is less susceptible to cracking, warping, deformation, brittle fracture, etc., thereby enhancing the service life of the security device 10.

As shown, the safety device 10 includes a first arm 11 and a second arm 12 at least partially connected together. It will be appreciated by those skilled in the art that the division of the first arm 11 and the second arm 12 herein may be primarily for convenience of description. As described above, the first arm 11 and the second arm 12 may be made of the same material and integrally molded as the safety device 10.

In some embodiments, as shown in fig. 2, the security device 10 has a first plane of symmetry 101. The first arm 11 and the second arm 12 are arranged mirror-symmetrically with respect to the first plane of symmetry 101. In some embodiments, as shown in fig. 3, the security device 10 further comprises a second plane of symmetry 102. The security device 10 may be mirror symmetric about the second plane of symmetry 102. Optionally, the second symmetry plane 102 is perpendicular to the first symmetry plane 101. Providing the security device 10 with a symmetrical configuration may further facilitate use of the security device 10 and increase its useful life. In particular, as shown in fig. 3, the security device 10 includes opposing first and second faces 14, 15. Both the first side 14 and the second side 15 of the security device 10 may face the rotation control when the security device 10 is in use. In this manner, a user may alternately place the first side 14 and the second side 15 of the security device 10 facing the rotational controller, thereby providing even wear on the first side 14 and the second side 15 and increasing the useful life of the security device 10.

As shown in fig. 1, the first arm 11 includes a first root end 113 and a first free end 115 opposite to each other, and the second arm 12 includes a second root end 123 and a second free end 125 opposite to each other. Specifically, the first root end 113 of the first arm 11 and the second root end 123 of the second arm 12 are coupled together. As shown, the first root end 113 of the first arm 11 and the second root end 123 of the second arm 12 are integrally formed in a generally rectangular plate-like configuration. It should be understood by those skilled in the art that the first root end 113 of the first arm 11 and the second root end 123 of the second arm 12 may be connected together to form other shaped structures, and the application is not limited thereto.

As shown in fig. 1, the first arm 11 and the second arm 12 are at least partially spaced apart to define a through slot 13. In particular, first arm 11 and second arm 12 are spaced apart from each other at a portion remote from first root end 113 and second root end 123 to define a through slot 13. The through slots 13 may be substantially linear through slots 13. Alternatively, the through slot 13 is symmetrical about the first plane of symmetry 101 of the safety device 10. The width of the through grooves 13 is substantially uniform. Optionally, the width of the through slot 13 is 11 mm.

As shown in fig. 1, the through slot 13 includes opposing first and second ends 131, 132. Specifically, the first end 131 of the channel 13 is proximate to the first root end 113 of the first arm 11 and the second root end 123 of the second arm 12, and the second end 132 of the channel 13 is proximate to the first free end 115 of the first arm 11 and the second free end 125 of the second arm 12.

In some embodiments, the through slot 13 includes an opening 135 at the second end 132, the opening 135 allowing access to a lever of the rotary controller. When the lever passes through the opening 135, the first free end 115 of the first arm 11 and the second free end 125 of the second arm 12 can be elastically separated toward both sides. The first free end 115 of the first arm 11 and the second free end 125 of the second arm 12 may return to their original positions after the control rod is passed through the opening 135. Through the opening 135 of the through slot 13, the safety device 10 can be installed and removed without disassembling the rotary controller.

In some embodiments, the through slot 13 further includes a rounded corner 137 or chamfered portion at the first end 131. The rounded corners 137 or chamfered portions ensure a smooth connection of the first arm 11 and the second arm 12 at the first end 131 of the through slot 13, reducing stress concentrations throughout the safety device 10.

Optionally, and with particular reference to fig. 1, the first arm 11 further comprises a first hook 117. A first hook 117 extends from the first free end 115 of the first arm 11 towards the through slot 13. The second arm 12 further comprises a second hook 127, the second hook 127 extending from the second free end 125 towards the through slot 13. The first and second hooks 117, 127 partially block the opening 135 of the through slot 13 at the second end 132 of the through slot 13. Optionally, the width of the opening 135 between the first hook 117 and the second hook 127 is 5 millimeters. Upon mounting the safety device 10 to the cooktop appliance, the first hook 117 and the second hook 127 can cooperate with each other, preventing the safety device 10 from disengaging from the cooktop appliance.

Referring to fig. 4, fig. 4 shows an enlarged view of the first hook 117 and the second hook 127. As shown, the first hook 117 includes a first leading side 1171 and a first stop side 1172, the first leading side 1171 being located outside of the channel 13, the first stop side 1172 facing toward the channel 13. Second hook 127 includes a second leading side 1271 and a second stop side 1272, second leading side 1271 being located outside through slot 13, and second stop side 1272 facing through slot 13.

In particular, the first and second guide sides 1171, 1271 may be generally linear guide sides. Specifically, the first leading side 1171 slopes away from the first arm 11, i.e., towards the middle of the through slot 13, as it extends in a direction from the first free end 113 to the first root end 115 of the first arm 11. Specifically, the second leading side 1271 is inclined in a direction away from the second arm 12, i.e., toward the middle of the through groove 13, when extending in a direction from the second free end 123 of the second arm 12 to the second root end 125.

Specifically, when safety device 10 is installed, first leading side 1171 and second leading side 1271 may cooperate to guide the lever of the rotary controller through opening 135 of channel 13 and into channel 13.

With further reference to fig. 4, the first stop side 1172 may be an arcuate side and the second stop side 1272 may be an arcuate side. After safety device 10 is installed to the cooktop appliance, first stop side 1172 and second stop side 1272 may cooperate to prevent lever 25 of rotary controller 21 from disengaging from through slot 13 of safety device 10.

As shown in fig. 4, the first hook 117 further includes a first transition side 1173 connected between the first leading side 1171 and the first stopping side 1172, and the second hook 127 further includes a second transition side 1273 connected between the second leading side 1271 and the second stopping side 1272. The first and second transition sides 1173, 1273 may have an at least partially arcuate shape.

Referring again to fig. 2 and 3, the first arm 11 includes a first constant thickness portion 118 and a first variable thickness portion 119. The first variable thickness portion 119 has a thickness greater than or equal to the thickness of the first equal thickness portion 118. The thickness of first uniform thickness portion 118 refers to the thickness of first uniform thickness portion 118 between first side 14 and second side 15. The thickness of the first variable thickness portion 119 refers to the thickness of the first variable thickness portion 119 between the first face 14 and the second face 15. Optionally, first equal thickness portion 118 is 4.5 millimeters thick. The thickness of the first variable thickness portion 119 is 4.5 mm at the minimum and 11.84 mm at the maximum.

As shown in fig. 2, first constant thickness portion 118 includes a first free end 115, and first constant thickness portion 118 abuts through slot 13. The first variable thickness portion 119 includes a first root end 113. Optionally, the first variable thickness portion 119 at least partially abuts the through slot 13. Optionally, the thickness of the first variable thickness portion 119 gradually increases in a direction from the first free end 115 to the first heel end 113. Optionally, the thickness of the first variable thickness portion 119 increases linearly or non-linearly in a direction from the first free end 115 to the first root end 113, which is not limited in this application.

Referring to fig. 2 and 3, similar to the first arm 11, the second arm 12 includes a second equal thickness portion 128 and a second variable thickness portion 129. The thickness of the second variable thickness portion 129 is greater than or equal to the thickness of the second equal thickness portion 128. The thickness of second equal-thickness portion 128 refers to the thickness of second equal-thickness portion 128 between first face 14 and second face 15. The thickness of the second variable thickness portion 129 refers to the thickness of the second variable thickness portion 129 between the first face 14 and the second face 15. Optionally, second equal-thickness portion 128 has a thickness of 4.5 millimeters. The thickness of the second variable thickness portion 129 is 4.5 mm at the minimum and 11.84 mm at the maximum.

As shown in FIG. 2, second equal-thickness portion 128 includes a second free end 125, and second equal-thickness portion 128 abuts channel 13. The second variable thickness portion 129 includes a second root end 123. Optionally, second variable thickness portion 129 at least partially abuts through slot 13. The thickness of the second variable thickness portion 129 increases gradually in a direction from the second free end 125 to the second root end 123. Optionally, the thickness of the second variable thickness portion 129 increases linearly or non-linearly in a direction from the second free end 125 to the second root end 123, which is not limited in this application.

Referring to fig. 1-3, as shown, the first variable thickness portion 119 may include a first resistance enhancing structure 1192 on a surface thereof, and the second variable thickness portion 129 includes a second resistance enhancing structure 1292 on a surface thereof. Optionally, the first resistance enhancing structure 1192 and the second resistance enhancing structure 1292 are raised or embossed. The first and second resistance enhancing structures 1192 and 1292 shown in fig. 2 are circular bumps. It will be understood by those skilled in the art that the first resistance increasing structure 1192 and the second resistance increasing structure 1292 may be ridges, arcuate projections, etc., as the present application is not limited in this respect.

Optionally, the surfaces of the first variable thickness portion 119 and the second variable thickness portion 129 may be coated with a resistance increasing film or coating for enhancing the locking capability of the security device 10 to the rotary controller 21.

Refer to fig. 5 to 8. Wherein fig. 5 shows a side view of a part of the hob device 20, fig. 6 shows a schematic view of the hob device 20 in fig. 5 with the safety device 10 installed, fig. 7 shows a side view of the hob device 20 in fig. 5 in an unlocked state, and fig. 8 shows a side view of the hob device 20 in fig. 5 in a locked state. The hob device 20 may be, for example, a gas cooker or other hob, to which the present application is not limited.

As shown in fig. 5, a hob device 20 (also called a cooking device or cooking hob) comprises a rotation control 21 and a control surface 23. The control surface 23 may be part of the housing of the hob device 20. The control surface 23 is spaced apart from the rotary control 21 by a first gap 28. The hob device 20 further comprises a control rod 25. One end of the control rod 25 is fixedly connected to the rotary controller 21, and the other end of the control rod 25 extends into the control surface 23 and is connected with a corresponding mechanism in the control surface 23.

Referring to fig. 6, the safety device 10 described above may be mounted to a cooktop appliance 20. Specifically, the safety device 10 may be disposed in the first gap 28. When the safety device 10 is installed, the control rod 25 of the hob device 20 may pass through the opening 135 of the through slot 13 into the through slot 13 under guidance of the first guiding side 1171 of the first hook 117 and the second guiding side 1271 of the second hook 127 of the safety device 10. One of the first face 14 or the second face 15 of the security device 10 may face the rotary controller 21 when the security device 10 is installed.

Referring to fig. 7, the cooktop appliance 20 in fig. 7 is in an unlocked state. Specifically, after the safety device 10 is installed and the control lever 25 enters the through slot 13, the rotary controller 21 of the cooktop device 20 is first in the unlocked state. At this point, first equal-thickness portion 118 and second equal-thickness portion 128 of security apparatus 10 may be at least partially positioned under rotational controller 21. First equal-thickness portion 118 and second equal-thickness portion 128 are the same thickness and are less than the height of first gap 28. The width of the through slot 13 of the safety device 10 is greater than or equal to the width of the control rod 25. At this time, the safety device 10 can freely move with respect to the lever 25 and the rotary controller 21.

Referring to fig. 8, the cooktop appliance 20 in fig. 8 is in a locked state. In particular, the user may move the safety device 10 so that the control rod 25 of the hob device 20 is closer to the first root end 113 of the first arm 11 and the second root end 123 of the second arm 12. At this time, the first variable thickness portion 119 and the second variable thickness portion 129 of the safety device 10 reach under the rotation controller 21 and engage with the rotation controller 21 to prevent the rotation of the rotation controller 21, thereby achieving the purpose of locking the rotation controller 21. In particular, the thickness of the first variable thickness portion 119 and the thickness of the second variable thickness portion 129 of the security device 10 are at least partially greater than the height of the first gap 28. Accordingly, the first and second variable thickness portions 119 and 129 of the security device 10 may become lodged within the first gap 28, acting as a lock to the rotation controller 21. Particularly in the case where the rotary controller 21 is a push-and-turn type controller, the first variable thickness portion 119 and the second variable thickness portion 129 caught in the first gap 28 may prevent a user from pushing the rotary controller 21, thereby preventing the rotary controller 21 from rotating.

Specifically, when it is desired to unlock rotary control 21, the user may push or pull security apparatus 10 to move lever 25 from adjacent first root end 113 and second root end 123 to adjacent first free end 115 and second free end 125. Specifically, when it is desired to remove security device 10, a user may push or pull security device 10 to move lever 25 away from channel 13 from opening 135 of channel 13.

The present application allows a user to install and detach the safety device 10 in a simple push-pull manner by providing the through groove 13 and the first and second hooks 117 and 127 at one end of the through groove 13, and allows the safety device 10 to remain installed on the cooktop device 20 in an unlocked state of the rotary controller 21, preventing the safety device 10 from being lost.

The above description is only for the purpose of illustrating embodiments of the present invention and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent transformations that can be implemented by using the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
