Detailed Implementation

[0034] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] In the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Moreover, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this application, the terms "first," "second," etc., are used to distinguish different objects and should not be construed as indicating or implying a specific order or hierarchy, or implicitly specifying the number of technical features indicated. Therefore, a feature marked "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0038] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In the description of this application, the term "and / or" indicates that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0040] In the description of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 80° to 90°, the two directions can be considered perpendicular; if the angle between two directions is 0° to 10°, the two directions can be considered parallel.

[0041] With socio-economic development, people's material lives are becoming increasingly affluent, and their demands for spiritual fulfillment are also rising. This is especially true for marital relationships, where improved sexual quality is crucial for family happiness and harmony. Existing adult products, such as positioning pads and fertility pillows, merely enhance traditional sexual positions; they are essentially still traditional positions and do not significantly improve the quality of sexual life for both partners or the woman's chances of pregnancy. Therefore, how to improve the quality of sexual life for both partners and the woman's chances of pregnancy is a pressing technical problem that needs to be solved in this field.

[0042] To solve the above technical problems, such as Figure 1 , Figure 2 and Figure 4As shown, an embodiment of this application provides a positioning chair 100, including: a frame 110, an inclined plate 120, a first support member 130, and a second support member 140.

[0043] The frame 110 is placed vertically on the ground and defines a receiving space 114. The inclined plate 120 is located within the receiving space 114 and is connected to the frame 110. The preset angle formed by the inclined plate 120 relative to the vertical direction is α, which satisfies: 0°≤α≤50°. The first support member 130 is located below the inclined plate 120 in the vertical direction and is connected to the frame 110. The second support member 140 is located above the inclined plate 120 in the vertical direction and is connected to the frame 110. The second support member 140 is used to open or close the receiving space 114.

[0044] For example, the preset angle α can be any value from 0°, 2°, 5°, 8°, 10°, 15°, 19°, 20°, 25°, 30°, 35°, 40°, 45°, 50° or any value from any combination of two of them, without any specific limitation.

[0045] It is understood that, when using the positioning chair 100 provided in this embodiment, exemplarily, the frame 110 is placed against the edge of the bed 200, the receiving space 114 is opened through the second support member 140, the woman 300's legs are on the bed 200, her buttocks and above enter the receiving space 114 and lie down along the inclined plate 120, her arms are supported on the first support member 130, so that the woman 300's buttocks and above are maintained at the aforementioned preset angle with the vertical direction, that is, at any value between 0° and 50°, and the man 400 lies horizontally on top of the woman 300, with his buttocks and above resting on the second support member 140. The specific position formed with the assistance of the positioning chair 100 provided in this embodiment can effectively improve the quality of sexual life for both men and women, and is more conducive to the woman 300's pregnancy.

[0046] Specifically, the main reason why the aforementioned specific positions can effectively improve the quality of sexual life and are conducive to the woman's pregnancy is that: the woman's upper body is positioned at an angle between 0° and 50° to the vertical direction, with the vaginal opening naturally facing upwards. This allows the vagina to naturally tighten and narrow under the influence of gravity from surrounding tissues, making the vagina more compact and tighter. Simultaneously, the G-spot is precisely at the point of impact when the man inserts from above, making it more easily stimulated. Furthermore, the man's downward movements allow for deeper penetration and a more complete reach, bringing the ejaculation point closer to the cervix.

[0047] It should be noted that the above-described method of resting the frame 110 against the edge of the bed 200 is only an exemplary use case, namely, the use of the positioning chair 100 in conjunction with the bed 200. Depending on the user's preference, the frame 110 can also be rested against other soft furniture, such as sofas or recliners. No specific restrictions are placed on the use case of the positioning chair 100 here. In addition, the second support member 140 is not only used to support the man's buttocks and above, but also to open or close the receiving space 114 so that the woman's buttocks and above can better enter the receiving space 114 and lie down along the inclined plate 120.

[0048] In one embodiment, the following condition is satisfied: 30°≤α≤50°.

[0049] Understandably, by controlling the preset angle α within the range of 30° to 50°, the quality of sexual life for both men and women can be further improved.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment, one side of the inclined plate 120 is rotatably connected to the frame 110, and the other side of the inclined plate 120 is provided with a pin hole 121 communicating with the receiving space 114. The chair 100 also includes an adjustment pin 161. The frame 110 is provided with a plurality of adjustment holes 115 at intervals, each adjustment hole 115 communicating with the receiving space 114. The adjustment pin 161 is provided through the pin hole 121 and one of the adjustment holes 115.

[0051] For example, the number of adjustment holes 115 can be two, three, four, five, six, etc., without any specific limitation.

[0052] It is understandable that, since the preset angle α varies slightly for different women, when using the positioning chair 100, the angle of the inclined plate 120 can be adjusted by inserting the adjusting pin 161 into different adjusting holes 115 to meet the needs of different users.

[0053] For example, the following conditions are met: 30°≤α≤50°, and the number of adjustment holes 115 is five, with an angle of 5° between two adjacent adjustment holes 115, thereby enabling the inclined plate 120 to be adjusted within the range of 30° to 50°, with a minimum adjustment unit of 5°.

[0054] like Figure 2 and Figure 3As shown, in one embodiment, the frame 110 includes a first mounting plate 111 and a second mounting plate 112 spaced apart from each other, an inclined plate 120 is connected between the first mounting plate 111 and the second mounting plate 112, a first support member 130 is connected between the first mounting plate 111 and the second mounting plate 112, and a second support member 140 includes a first support plate 141 and a second support plate 142. The first support plate 141 is movably connected to the first mounting plate 111, and the second support plate 142 is movably connected to the second mounting plate 112.

[0055] Understandably, the arrangement of the first mounting plate 111 and the second mounting plate 112 facilitates the installation of the first support member 130, the first support plate 141, and the second support plate 142. Furthermore, the movable connection between the first support plate 141 and the first mounting plate 111, and the movable connection between the second support plate 142 and the second mounting plate 112, facilitates the opening and closing of the receiving space 114, thereby allowing the woman 300's buttocks and above to better enter the receiving space 114 and lie down along the inclined plate 120.

[0056] like Figure 3 and Figure 5 As shown, one side of the first support plate 141 is rotatably connected to the first mounting plate 111, and one side of the second support plate 142 is rotatably connected to the second mounting plate 112.

[0057] Understandably, when the first support plate 141 and the second support plate 142 rotate in opposite directions, the receiving space 114 can be opened, so that the woman 300's buttocks and above can better enter the receiving space 114 and lie down along the inclined plate 120; when the first support plate 141 and the second support plate 142 rotate in opposite directions, the receiving space 114 can be closed, and it is used to support the man 400's buttocks and above, so that the man 400 can lie horizontally on top of the woman 300.

[0058] Of course, in the above embodiment, the first support plate 141 can also be slidably connected to the first mounting plate 111, and the second support plate 142 can be slidably connected to the second mounting plate 112. In this way, when the first support plate 141 and the second support plate 142 slide away from each other, the receiving space 114 can be opened, so that the woman 300's buttocks and above can better enter the receiving space 114 and lie down along the inclined plate 120; when the first support plate 141 and the second support plate 142 slide towards each other, the receiving space 114 can be closed, and it can be used to support the man 400's buttocks and above, so that the man 400 can lie horizontally on top of the woman 300.

[0059] like Figure 3 and Figure 6As shown, further, the positioning chair 100 also includes a first rotating hinge 162 and a second rotating hinge 163. One side of the first rotating hinge 162 is connected to the side of the first mounting plate 111 opposite to the second mounting plate 112, and the other side of the first rotating hinge 162 is connected to the side of the first support plate 141 opposite to the first mounting plate 111. One side of the second rotating hinge 163 is connected to the side of the second mounting plate 112 opposite to the first mounting plate 111, and the other side of the second rotating hinge 163 is connected to the side of the second support plate 142 opposite to the second mounting plate 112. The first and second support plates 141 and 142 are rotatably connected to the frame 110 via the first rotating hinge 162 and the second rotating hinge 163. At the same time, when the second support member 140 closes the receiving space 114, the side of the first support plate 141 facing the first mounting plate 111 abuts against the first mounting plate 111, and the side of the second support plate 142 facing the second mounting plate 112 abuts against the second mounting plate 112. This stabilizes the first and second support plates 141 and 142 in a horizontal position to support the upper part of the buttocks of the male 400.

[0060] Of course, in the above embodiments, the first support plate 141 and the second support plate 142 can also be rotatably connected to the frame 110 through the first rotating shaft and the second rotating shaft. Specifically, the first support plate 141 is rotatably connected to the first mounting plate 111 through the first rotating shaft, and the second support plate 142 is rotatably connected to the second mounting plate 112 through the second rotating shaft.

[0061] like Figure 2 and Figure 3 As shown, the frame 110 further includes a third mounting plate 113, which is connected between the first mounting plate 111 and the second mounting plate 112. The first mounting plate 111, the second mounting plate 112 and the third mounting plate 113 together define the accommodating space 114.

[0062] It is understandable that the first mounting plate 111, the second mounting plate 112 and the third mounting plate 113 can be used to enclose and form a receiving space 114. When the woman 300 lies down along the inclined plate 120 with her buttocks and above, and the second support member 140 closes the receiving space 114, the woman 300 is surrounded and covered by the frame 110, which can increase the experience for both men and women.

[0063] like Figure 2 As shown, in one embodiment, the positioning chair 100 also includes a height adjustment component 170, which is connected to the bottom of the frame 110 in the vertical direction and is used to adjust the distance between the frame 110 and the ground so as to adjust the height of the positioning chair 100 according to the height of the bed 200, sofa and other soft furniture, thereby achieving the adaptation of the positioning chair 100 to the soft furniture.

[0064] like Figure 2 and Figure 3 As shown, the height adjustment component 170 further includes a plurality of foot cups 171, with adjacent foot cups 171 spaced apart, and each foot cup 171 is threadedly connected to the frame 110.

[0065] Understandably, the multiple foot cups 171 facilitate the adjustment of the height of the positioning chair 100, thereby enabling the positioning chair 100 to be adapted to upholstered furniture.

[0066] Of course, in the above embodiment, the height adjustment component 170 can also be a telescopic tube. The telescopic tube includes a first tube body, a second tube body, a spring, and a steel ball. The first tube body is sleeved on the second tube body. The first tube body is provided with multiple positioning holes. The spring is connected between the second tube body and the steel ball. When the steel ball is pressed, the steel ball can slide out from one positioning hole and lock into another adjacent positioning hole under the elastic action of the spring, thereby realizing the length extension and retraction adjustment of the telescopic tube. In this way, the height of the chair 100 can also be adjusted.

[0067] In one embodiment, the positioning chair 100 further includes a third support member connected to the frame 110 and located on the side of the inclined plate 120 away from the first support member 130. This allows the positioning chair 100 to be used without the need for soft furniture such as a bed 200 or sofa; that is, when using the positioning chair 100, both the man's (400) and woman's (300) legs can rest on the third support member.

[0068] In one specific embodiment, the positioning chair 100 includes a frame 110, an inclined plate 120, a first support member 130, a second support member 140, an adjusting pin 161, and a height adjusting member 170. The frame 110 is placed vertically on the ground and includes a first mounting plate 111, a second mounting plate 112, and a third mounting plate 113. The third mounting plate 113 is connected between the first mounting plate 111 and the second mounting plate 112. The first mounting plate 111, the second mounting plate 112, and the third mounting plate 113 together define an accommodating space 114. One side of the inclined plate 120 is rotatably connected to the first mounting plate 111 and the second mounting plate 112, and the other side of the inclined plate 120 is provided with a pin hole 121 communicating with the accommodating space 114. The first mounting plate 111 and / or the second mounting plate 112 are provided with multiple adjusting holes 115, each adjusting hole 115 communicating with the accommodating space 114 for adjustment. Pin 161 is disposed in pin hole 121 and one of the adjustment holes 115. The preset angle formed by inclined plate 120 and vertical direction is α, which satisfies: 0°≤α≤50°. First support member 130 is connected between first mounting plate 111 and second mounting plate 112. Second support member 140 includes first support plate 141 and second support plate 142. First support plate 141 is rotatably connected to first mounting plate 111 through first rotating hinge 162. Second support plate 142 is rotatably connected to second mounting plate 112 through second rotating hinge 163. Height adjustment member 170 includes multiple foot cups 171. Adjacent foot cups 171 are spaced apart. Each foot cup 171 is threadedly connected to frame 110.

[0069] Based on the above structure, when using the positioning chair 100, for example, the frame 110 is placed against the edge of the bed 200, and the height of the positioning chair 100 is adjusted by the footrest 171 so that the positioning chair 100 is level with the height of the bed 200. The preset angle α of the inclined plate 120 is adjusted by the adjusting pin 161 and the adjusting hole 115, for example, the preset angle α is adjusted to 50°. The first support plate 141 and the second support plate 142 are opened so that the first support plate 141 and the second support plate 142 are in a vertically open receiving space 114 state. The woman 300 lies horizontally on the bed 200, with her buttocks and above entering the receiving space 114 and lying down along the inclined plate 120. Her arms are supported on the first support member 130, and her head is resting on the first support member 130, so that the woman 300's buttocks and above are maintained at the above-mentioned preset angle with the vertical direction. The man 400 opens the first support plate 141 and the second support plate 142. The bed 200 is closed, so that the first support plate 141 and the second support plate 142 are in the state of horizontally closed receiving space 114. The man 400 lies horizontally on top of the woman 300, with his legs spread outside the woman 300's legs (or inside the woman 300's legs). The man 400's lower body is level with the woman 300, supported by the bed 200. The man 400's upper body lies on the first support plate 141 and the second support plate 142, so that the man 400's body is balanced and his weight does not press on the woman 300 (the man 400 can also not lie on the first support plate 141 and the second support plate 142, but support his arms directly on the first support member 130, thereby using his hands to keep his body horizontal). The man 400 moves from top to bottom, and the woman 300 moves from bottom to top or remains still, realizing the union of the man and woman in the above-mentioned specific position.
