Description

Technical Field

[0001] This utility model relates to the field of waist stool technology, and in particular to an assembled stool core and waist stool. Background Technology

[0002] A hip seat, unlike a baby carrier, is a new type of childcare tool that is strapped to the parent's waist like a chair. Ergonomically designed, it is safe, comfortable, and stylish. A hip seat effectively relieves the strain on the shoulders and back when carrying a baby by hand. It is more convenient to carry than a stroller and is more suitable for outings with a baby. The hip seat mainly consists of an internal seat core and a soft material covering the outer surface of the core. The core provides support and is mostly made of hard materials. The baby sits on the upper surface of the hip seat. This type of hard seat core fits tightly against the adult's waist and abdomen, which is the main area of ​​stress. When walking, it is easy to continuously touch and press on the adult's waist and abdomen, causing discomfort or pain. Currently, a modular seat core has appeared on the market, which uses soft and hard materials in separate sections. The support body against the abdomen is made of soft material, while the sitting body for supporting the baby is made of hard material, in order to balance the comfort of both the baby and the adult. However, the assembly structure when the support body and the sitting body are assembled together is relatively complex, which not only increases the manufacturing process and cost, but also has poor stability after long-term use. Utility Model Content

[0003] The purpose of this utility model is to design an assembled stool core and waist stool to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs an assembled stool core, including a support body and a seating body. The support body and the seating body abut against each other and are connected at their abutment surfaces by a concave-convex connection structure. The concave-convex connection structure includes a protrusion on the support body and a recess on the seating body; or, the concave-convex connection structure includes a recess on the support body and a protrusion on the seating body; wherein the longitudinal cross-sectional shapes of the protrusion and the recess are adapted to each other; the protrusion includes a convex head and a concave neck, the convex head extends along the normal direction of the abutment surface and protrudes relative to the concave neck on its upper and / or lower sides.

[0005] Preferably, the protrusion is made of a soft material and has elastic deformation capability, and the opening width of the concave part is smaller than the thickness of the protrusion in the uncompressed state and not less than the thickness of the protrusion in the compressed state.

[0006] Further optimization involves the concave-convex connection structure being located on the abutting surface, and the concave-convex connection structure extending laterally or vertically.

[0007] Further optimization involves the protrusion being a horizontally arranged convex strip integral with the corresponding abutment surface, and the concave portion being a horizontally arranged groove integral with the corresponding abutment surface.

[0008] Further optimization is achieved by making the longitudinal cross-sectional shape of the protrusion T-shaped, circular, or near-circular.

[0009] Further optimization involves a smooth transition between the convex head and the abutment surface via a concave neck, and an edge protrusion on the concave portion that can engage with the concave neck in a shape-matching manner.

[0010] Further optimization involves the seating body and the support body being distributed front to back. The outer surface of the support body includes a front end face 1 serving as a contact surface and a rear end face 1 serving as a contact surface. The outer surface of the seating body includes a rear end face 2 serving as a contact surface and a front end face 2 serving as a suspended end. The outer surface of the support body also includes a left side face 1 and a right side face 1. The outer surface of the seating body also includes a left side face 2 and a right side face 2. The two end faces of the convex and concave portions are flush with the corresponding left and right side faces, respectively.

[0011] Preferably, the support body is made of a soft material, and the seating body is made of a rigid material.

[0012] Further optimization involves the convex portion consisting of at least two laterally discontinuous sections.

[0013] This utility model also designs a waist stool, including the above-mentioned assembled stool core.

[0014] The technical effects of this utility model are as follows:

[0015] 1. The stool core uses a soft support body and a hard seating body. The support body rests against the adult's abdomen, and the seating body is located in front of the support body. The end face between the support body and the seating body serves as the contact surface. The two contact surfaces are connected by a concave-convex connection structure, which includes a convex part and a concave part, respectively set on the two contact surfaces and integrally connected with the corresponding contact surfaces. The soft convex part can be directly inserted into the hard concave part to form a concave-convex fit to realize the connection between the support body and the seating body. The connection is convenient and firm, and the support body and the seating body are not easy to detach from each other.

[0016] 2. Both ends of the convex and concave parts extend to the left and right sides of the corresponding support and seating body, and are flush with the corresponding left and right sides, so that the convex part can be inserted into the groove from either end of the concave part and assembled by sliding, thereby realizing different assembly methods and making the loading and unloading operation simple and convenient.

[0017] 3. The longitudinal cross-sections of the convex and concave parts can be T-shaped, circular, or near-circular, which not only facilitates assembly but also provides a large contact area and a large static friction between the two contact surfaces, resulting in strong interlocking and better stability of the convex-concave fit.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0029] like Figure 1 As shown, this embodiment provides a stool core, which includes a support body 1 and a seating body 2. The support body 1 is a soft body, that is, the support body 1 can be made of soft material, or the outer surface is made of soft material; the seating body 2 is a hard body, that is, the seating body 2 can be made of hard material, or the outer surface is made of hard material. The support body 1 and the seating body 2 are distributed front to back and abut against each other. The abutting surfaces of the two are connected by a concave-convex connection structure to form a fit, so that the support body 1 and the seating body 2 are assembled to form a complete waist stool core.

[0030] The concave-convex connection structure includes a protrusion 3 and a concave portion 4. One of the protrusions 3 and the concave portion 4 protrudes onto the abutment surface of the support body 1, and the other is concave onto the abutment surface of the seat body 2. That is, the protrusion 3 can be set on the abutment surface of the support body 1 or the abutment surface of the seat body 2; the concave portion 4 can be set on the abutment surface of the seat body 2 or the abutment surface of the support body 1. The protrusion 3 and the concave portion 4 are connected by a concave-convex fit, that is, the cross-sectional shapes of the two can be matched, so that the support body 1 and the seat body 2 can be detachably connected.

[0031] It should be noted that the support body 1 and the seating body 2 are connected by a concave-convex connection structure, and their contact surfaces also fit together.

[0032] The concave-convex connection structure is located on the abutting surface. After assembly, the concave-convex connection structure extends horizontally or vertically. Here, horizontal and vertical are defined relative to the abutting surface, so that when the support body 1 and the riding body 2 abut against each other and the concave-convex fit is convenient to fit together, and the connection positioning stability is guaranteed to the greatest extent. With the help of the back strap or waist belt, the support body 1 and the riding body 2 will not be misaligned.

[0033] The outer surface of the support body 1 includes a front face 11, a rear face 12, a left face 13, and a right face 14. The front face 11 serves as the contact surface, and the rear face 12 serves as the abdominal contact surface. The abdominal contact surface is usually concave to facilitate a comfortable fit between the support body 1 and the adult's abdomen. The outer surface of the seating body 2 includes a front face 21, a rear face 22, a left face 23, and a right face 24. The rear face 22 serves as the contact surface, and the front face 21 is located at the front as the suspended end. The outer surface of the seating body 2 also includes an upper surface, which serves as the seating surface.

[0034] In this embodiment, the protrusion 3 is a horizontally arranged protrusion, that is, the protrusion extends left and right along the corresponding abutment surface and is integrally designed with the abutment surface; from the longitudinal cross-section, the recess 4 is a horizontally arranged groove and is integrally designed with the corresponding abutment surface.

[0035] The surfaces of the protrusions and grooves are mutually adaptable curved surfaces, or they can be square or trapezoidal to form a mating structure similar to a tenon joint.

[0036] The protrusion 3 includes a protruding head 31 and a concave neck 32. The concave neck 32 is located on both sides of the protruding head 31. The protruding head 31 is smoothly connected to the abutting surface through the concave neck 32. The protruding head 31 is convex relative to the concave neck 32. In this embodiment, the protruding head 31 is cylindrical or quasi-cylindrical, that is, the longitudinal cross-section of the protruding head is T-shaped, circular or quasi-circular. The quasi-circular shape can be teardrop-shaped, elliptical, or U-shaped with an inward concave neck, etc. In this embodiment, the concave neck 32 is an inward concave arc surface or curved surface. The edge of the groove 4 and the corresponding abutting surface form an arc-shaped edge protrusion 41, so that the edge protrusion 41 and the concave neck 32 cooperate with each other to form a certain engagement, so that the protrusion 3 and the concave 4 form a stable fit, realizing that the soft protrusion 3 can be directly inserted into the hard concave 4 to form a stable fit, that is, the protrusion 3 can be directly snapped into the concave 4 to form a fit.

[0037] The outer surface of the support body 1 also includes a left side surface 13 and a right side surface 14, and the outer surface of the seat body 2 also includes a left side surface 23 and a right side surface 24. The two end faces of the protrusion 3 and the concave part 4 are flush with the corresponding left side surface and right side surface, respectively. The purpose of this design is that the protrusion 3 and the concave part 4 can slide into each other from either the left or right end to form an assembly. At the same time, the left side surface and the right side surface are both flat and smooth. The two ends of the protrusion 3 will not be of different lengths with the two ends of the concave part 4, thereby avoiding the support body 1 and the seat body 2 from being misaligned.

[0038] Furthermore, the contact surface can be inclined, meaning it forms a certain angle with the horizontal plane. This allows for a relatively balanced and stable assembly, with the friction between the contact surfaces and the fit between the protrusion 3 and the concave part 4, preventing misalignment and slippage between the support body 1 and the seat body 2. Of course, the contact surface can also be vertically oriented, depending on actual production needs.

[0039] Furthermore, after the two contact surfaces are fitted together, a longitudinal annular dividing line is formed on the surface of the entire seat core. The dividing line at the top is as close as possible to the support body 1, while the rear end face 12 of the support body 1 is recessed to maximize the area of ​​the upper surface of the seat body 2, so as to avoid pressing on the upper surface of the support body 1.

[0040] Furthermore, from the cross-section, the entire convex head 31 is tilted upward at a certain angle relative to the abutting surface. The convex head 31 extends normally onto the abutting surface, that is, it is perpendicular or relatively perpendicular to the abutting surface, allowing for appropriate deviation. In this way, the convex part 3 and the concave part 4 will not be easily misaligned due to the vertical load pressure.

[0041] In addition, the two contact surfaces can be straight or curved, with curved surfaces increasing the friction between the two contact surfaces.

[0042] Furthermore, the concave-convex connection structure is located at the middle position in the height direction of the contact surface, so that the friction between the contact surfaces can be evenly distributed at the top and bottom of the concave-convex connection structure, making the force on the concave-convex connection structure more uniform and stable, thereby enhancing the stability of the concave-convex fit.

[0043] The protrusion 3 can be a single, continuous protrusion structure or an intermittently distributed protrusion structure, such as... Figure 4 As shown, the discontinuous protrusion 3 consists of at least two parts, which are distributed laterally and can be simultaneously embedded into the integral recess 4 to form a fit.

[0044] The number of protrusions 3 and concave parts 4 is one. Of course, the number of protrusions 3 and concave parts 4 can also be multiple. The protrusions 3 and concave parts 4 are symmetrically or evenly distributed along the height or side direction of the contact surface.

[0045] This embodiment also provides a waist stool, which includes the aforementioned stool core and back strap. The support body 1 and the seating body 2 abut against each other to form a complete stool core, and the stool core is disposed in the back strap to form a waist stool.

[0046] It should be noted that, as Figure 2 As shown, the directional descriptions such as "horizontal", "vertical", "front", "back", "left", "right", "up", and "down" in all the above examples are defined by the orientation of the stool core in normal use, that is, the seating body 2 and the support body 1 are distributed in front and behind, the left and right direction is the horizontal direction, and the up and down direction is the vertical direction.

[0047] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
