Description

Technical Field

[0001] This utility model relates to a folding stool. Background Technology

[0002] The existing folding stools include a seat and cross-shaped legs. Such stools are simple and easy to use, but because the legs do not have a locking structure, if the user's center of gravity is unstable during use, the legs of the stool may move unexpectedly, causing the user to lose their sitting posture. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a folding stool with a stable structure when unfolded and used.

[0004] The technical solution adopted by this utility model to solve the above problems is: a folding stool, including a stool surface, stool legs, and mounting components for connecting the stool surface and stool legs. The stool legs include two support leg assemblies, each support leg assembly including a first support leg and a second support leg. The first support leg and the second support leg are crossed and rotatably connected. The two support legs are symmetrically arranged, and the two second support legs are fixedly connected by a second crossbar. The first support leg includes an inner segment and an outer segment. The inner segment and the outer segment are nested together and slidably connected. The inner segments of the two first support legs are fixedly connected by a first crossbar. The lower part of the stool surface is fixedly connected to the mounting component, the upper end of the second support leg is rotatably connected to the mounting component, and the upper end of the inner segment is rotatably connected to the mounting component. A pin is slidably connected along the length direction of the first crossbar, the length direction of the pin pointing radially towards the first support leg. The outer segment has a hole corresponding to the pin. The pin is connected to an elastic element, which applies a force to the pin to move towards the hole. When the folding stool is unfolded to the use state, when the inner segment and the outer segment slide until the pin and the hole are aligned, the pin is inserted into the hole under the action of the elastic element, thereby locking the inner segment and the outer segment, and thus locking the entire stool leg.

[0005] The upper sidewalls of the two outer segments of this invention have notches, which are located between the two outer segments. When the folding stool is unfolded into the use state, the first crossbar falls into the two notches.

[0006] The bottom of the notch in this invention supports the first horizontal bar.

[0007] In this invention, there is a gap between the first crossbar and the lower surface of the stool.

[0008] In this invention, a button for driving the movement of a latch is slidably connected to the first crossbar. The button extends below the first crossbar, and the direction of movement of the button is perpendicular to the direction of movement of the latch. The button has a pushing part with a first inclined surface. The latch has a corresponding active part. When the pushing part moves, the radial movement of the pushing part is converted into the axial movement of the latch by the action of the first inclined surface and the active part.

[0009] The active part of this utility model includes a second inclined surface, and the first inclined surface and the second inclined surface are in close contact.

[0010] The applied part of this invention includes a cavity into which the pushing part can be inserted, and the sidewall of the cavity has a second inclined surface.

[0011] The first support leg and the second support leg of this utility model are both circular metal tubes. The upper end of the second support leg is stamped into a semi-circle by the circular metal tube. The wall thickness of the two semi-circles is the same as the two wall thicknesses of the circular metal tube. The arc opening of the semi-circle faces away from the mounting component. The rotating shaft of the second support leg, which is rotatably connected to the mounting component, is set inside the semi-circle.

[0012] The mounting component of this utility model is formed by bending a metal sheet to form a horizontal part and a vertical part, which are fixedly connected. The horizontal part is close to the bottom of the stool surface. At the junction of the horizontal and vertical parts, there is a reinforcing part formed by stamping to connect the horizontal and vertical parts. The vertical part has two mounting positions, which extend away from the stool surface.

[0013] The stool surface of this utility model has a downwardly extending outer periphery, and the horizontal part is blocked by the outer periphery. An inner liner is provided between the inner segment and the outer segment. The inner liner is a plastic part and is located at the upper end of the outer segment.

[0014] The advantages of this utility model compared with the prior art are as follows: This invention features an inner and outer segment that slides together, allowing the first support leg to extend. The stool can be folded up to save space. When unfolded for use, the inner and outer segments slide together, shortening the first support leg. The position of the first support leg corresponds to the insertion hole of the rear pin, thus fixing the inner and outer segments. This makes the first support leg a fixed structure, and the entire stool leg a fixed structure, improving the stability of use. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] like Figure 1-3 As shown, the folding stool in this embodiment includes a stool surface 1, stool legs 2, and a mounting component 3 for connecting the stool surface 1 and stool legs 2. The stool legs 2 include two support leg assemblies 21. The support leg assembly 21 includes a first support leg 22 and a second support leg 23. The first support leg 22 and the second support leg 23 are crossed and rotatably connected. The two support legs are symmetrically arranged. The two second support legs 23 are fixedly connected by a second crossbar 311. The first support leg 22 includes an inner segment 24 and an outer segment 25. The inner segment 24 and the outer segment 25 are nested together and are slidably connected. The inner segments 24 of the two first support legs 22 are fixedly connected by a first crossbar 4. The lower part of the stool surface 1 is fixedly connected to the mounting component 3, the upper end of the second support leg 23 is rotatably connected to the mounting component 3, and the upper end of the inner segment 24 is rotatably connected to the mounting component 3. A pin 41 is slidably connected along the length of the first crossbar 4. The length of the pin 41 points to the radial direction of the first support leg 22. The outer segment 25 is provided with a hole 251 corresponding to the pin 41. The pin 41 is connected to an elastic element 42. The elastic element 42 applies a force to the pin 41 to move in the direction of the hole 251. When the folding stool is unfolded into its usable state, the inner segment 24 and the outer segment 25 slide until the pin 41 aligns with the hole 251. Under the action of the elastic element 42, the pin 41 inserts into the hole 251, thereby locking the inner segment 24 and the outer segment 25, and thus locking the entire stool leg 2. In this embodiment, when the stool is folded up, the inner segment 24 and the outer segment 25 slide together, extending the first support leg 22, allowing the stool to be folded away. When unfolded for use, the inner segment 24 and the outer segment 25 slide together, shortening the first support leg 22. Once the position aligns, the pin 41 inserts into the hole 251, fixing the inner segment 24 and the outer segment 25, making the first support leg 22 a fixed structure and the entire stool leg 2 a fixed structure. This improves the stability of use. When the stool needs to be folded up, the pin 41 disengages from the hole 251 to achieve folding.

[0020] In a preferred embodiment, the upper sidewalls of the two outer segments 24 each have a notch 252, which is located between the two outer segments 24. When the folding stool is unfolded to the use state, the first crossbar 4 falls into the two notches 252. In this embodiment, after the first crossbar 4 falls into the two notches 252, the inner segment 24 and the outer segment 25 are fixed radially by the first crossbar 4. The size of the notch 252 is equivalent to the outer diameter of the first crossbar 4, so the inner segment 24 and the outer segment 25 are stably connected radially.

[0021] In a preferred embodiment, the bottom of the notch 252 supports the first crossbar 4. The first crossbar 4 is supported by the bottom of the notch 252, thus forming a stable axial connection between the inner segment 24 and the outer segment 25.

[0022] In a preferred embodiment, there is a gap between the first crossbar 4 and the lower surface of the stool surface 1. In this embodiment, the gap between the first crossbar 4 and the lower surface of the stool surface 1 facilitates the operation and installation of the latch 41.

[0023] In a preferred embodiment, the first crossbar 4 is slidably connected to a button 5 for driving the movement of the pin 41. The button 5 extends below the first crossbar 4, and the direction of movement of the button 5 is perpendicular to the direction of movement of the pin 41. The button 5 has a pushing part 51, and the pushing part 51 has a first inclined surface 52. The pin 41 has a driven part 411 corresponding to the first inclined surface 52. When the pushing part 51 moves, the radial movement of the pushing part 51 is converted into the axial movement of the pin 41 by the action of the first inclined surface 52 and the driven part 411. In this embodiment, the first crossbar 4 is a plastic part, and the first crossbar 4 is long and narrow. The upper part of the first crossbar 4 has two through holes arranged along the length direction of the first crossbar 4. The pin 41 passes through the through holes, and its radial movement is restricted by the through holes, but it can move axially along the through holes. In a preferred embodiment, the driven part 411 includes a second inclined surface 412, and the first inclined surface 52 and the second inclined surface 412 are in close contact. The actuated part 411 includes a cavity 53 into which the pushing part 51 can be inserted, and the side wall of the cavity 53 has a second inclined surface 412. A cavity 53 into which the pushing part 51 can be inserted is provided on the first transverse member, and the side wall of the cavity 53 has a second inclined surface 412. The first inclined surface 52 of the pushing part 51 is in close contact with the second inclined surface 412, and the pushing part 51 and the cavity 53 form a sleeve installation, so the driving of the pin 41 by pressing the drive button 5 is more stable and reliable.

[0024] In a preferred embodiment, both the first support leg 22 and the second support leg 23 are circular metal tubes. The upper end of the second support leg 23 is stamped into a semi-circle from the circular metal tube, with the wall thickness of the two semi-circles being the two wall thicknesses of the circular metal tube. The arc opening of the semi-circle faces away from the mounting component 3. The rotating shaft 6, which is rotatably connected to the mounting component 3, is located inside the semi-circle. In this embodiment, the rotating shaft 6 can be a rivet. The rivet is located inside the semi-circle and is not exposed, avoiding the risk of burrs forming from exposed rivets that could injure the user. Because the rivet mounting area has a wall thickness of two thicknesses, the structure is stable, reliable, and has higher strength after installation.

[0025] In a preferred embodiment, the mounting component 3 is formed by bending a metal sheet to create a horizontal portion 31 and a vertical portion 32, which are fixedly connected. The horizontal portion 31 is close to the lower part of the stool surface 1. At the junction of the horizontal portion 31 and the vertical portion 32, there is a stamped reinforcing portion 33 connecting the horizontal portion 31 and the vertical portion 32. The vertical portion 32 has two mounting positions 321, which extend away from the stool surface 1. In this embodiment, the mounting component 3 is an integral mechanism, and the reinforcing portion 33 is also formed by stamping between the horizontal portion 31 and the vertical portion 32. Compared with welding, this method saves materials and processing costs while simultaneously increasing strength.

[0026] In a preferred embodiment, the outer periphery of the stool surface 1 has a downwardly extending outer periphery 11, the lateral portion 31 is covered by the outer periphery 11, and an inner liner 77 is provided between the inner segment 24 and the outer segment 25. The inner liner 77 is a plastic part and is located at the upper end of the outer segment 25. In this embodiment, the outer periphery 11 is fixedly connected to the stool surface 1. The outer periphery 11 covers part of the mounting part 3, enhancing the aesthetics. In another direction, the extension of the outer periphery 11 forms a hand grip area, making it convenient to hold.
