Description

TECHNICAL FIELD

[0001] The present application relates to the field of daily necessities, in particular to a configuration method of a single-handedly operable folding stool. BACKGROUND

[0002] As a daily necessity, folding stools have a small storage space and a wide range of applications. However, the folding stools currently in use require the use of both hands to open or fold the stool legs, which is inconvenient for single-handed operation and limits the range of applications.

[0003] As disclosed in the publication CN202820401U, a folding stool structure includes a stool surface and a support frame, the support frame includes an inner support frame and an outer support frame, the stool surface bottom is provided with a first fixed block and a second fixed block, the first fixed block is provided with a guide groove, the guide groove for the outer support frame to move is in the shape of a straight line, during the opening of the folding stool, the outer support frame moves in the middle section of the guide groove, the gravity of the stool surface on the support point of the outer support frame and the guide groove can be decomposed into a force in the horizontal direction and a force downward and obliquely at the lower end of the outer support frame, at the same time, the guide groove also has a friction force opposite to the horizontal direction of the outer support frame, the outer support frame needs to overcome the friction force when moving in the horizontal direction, and since the opening and closing movement of the outer support frame is actually arc-shaped, while the guide groove is designed in the shape of a straight line, the outer support frame will inevitably be restricted by the straight-line guide groove during the movement, that is, the outer support frame will move difficultly when reaching the middle section of the guide groove, and the folding stool cannot be easily opened and closed, and an external force needs to be applied on the stool surface or the support frame to achieve complete opening and closing.

[0004] Moreover, after multiple opening and closing actions, the straight-line guide groove of the outer support frame and the fixed block is prone to wear, which will cause the outer support frame to slide difficultly, and the folding stool may be stuck or difficult to fold completely during later use, therefore, the general damage rate of this type of folding stool is high, and the service life is not long.

[0005] On the contrary, if the guide groove at the bottom of the stool surface is in the shape of an arc, it is difficult to quickly move the outer support frame from one end to the other end of the guide groove with one hand during the opening and closing operation of the folding stool, and it is still necessary to hold the lower end of the support frame with both hands to control the direction, and the support frame may still move back and forth on the guide groove when the folding stool is carried by hand, and only when the folding stool is in the vertical direction can it be kept in a stable storage state, which increases unnecessary use restrictions. SUMMARY

[0006] In order to solve the above technical problems, the purpose of the present application is to provide a configuration method of single-handed operation folding stool, by changing the shape of the guide groove corresponding to the folding stool leg, the traditional folding stool is changed from the whole section type guide groove to two section type guide groove, the front section is a straight shape and the rear section is an arc shape, and the corner is arranged at the transition connection of the straight shape guide groove and the arc shape guide groove, so as to reduce the wear between the folding stool leg and the guide groove after the folding stool is used for many times, effectively improve the service life of the folding stool, and make the user no longer need to operate by hands in daily use, so that the user can easily realize the opening and closing of the folding stool by single-handed force.

[0007] The technical scheme of the present application is realized as follows:

[0008] A configuration method of single-handed operation folding stool,

[0009] I. Configuration and assembly of folding stool:

[0010] S1.1, prefabricate the guide rail, the guide rail is provided with a guide groove, the guide groove is divided into a straight shape guide groove and an arc shape guide groove in communication, and the corner is formed at the junction of the straight shape guide groove and the arc shape guide groove;

[0011] S1.2, install the stool leg, wherein the stool leg is divided into a long stool leg and a short stool leg, the upper end of the short stool leg is provided with a guide rod in advance, the guide rod is first inserted into the guide groove of the guide rail, and then the guide rail is installed at the bottom of the stool surface to complete the installation of the short stool leg; the upper end of the long stool leg is rotationally connected with the pre-set position of the bottom of the stool surface, wherein the hollow handle is further arranged on the stool surface, and the handle and the straight shape guide groove are close to the rotation position of the upper end of the long stool leg, and the pin shaft is punched at the intersection of the long stool leg and the short stool leg to realize the rotational connection therebetween;

[0012] II. Use of folding stool:

[0013] S2.1, open the folding stool in the storage state, in the storage state, the long stool leg and the short stool leg are overlapped together, and the stool surface is in a vertical and downward state; when opening, the user holds the handle with the wrist, and the stool surface is unfolded outward by the wrist force, then due to inertia, the long stool leg rotates, and the guide rod at the upper end of the short stool leg slides forward from the guide groove of the guide rail, at this time, the stool surface is upturned, so the guide rod of the short stool leg moves along the bottom of the straight shape guide groove which is the front section of the guide groove; when the guide rod moves through the corner, the guide rod comes to the boundary position of the straight shape guide groove and the arc shape guide groove, at this time, the wrist is released and no longer exerts force;

[0014] S2.2, after the folding stool is placed on the ground with the downward wrist, due to the gravity of the stool surface and the gravity of the stool leg, the guide rod will be attached to the top of the arc shape guide groove, and continue to slide along the shape of the arc shape guide groove, and finally reach the end of the guide groove, so as to realize the complete opening of the folding stool, and achieve the purpose of single-handed operation.

[0015] As preferred, one end of the guide rail is provided with a connecting hole, the other end of the guide rail is provided with a mounting part, and the bottom of the stool surface is provided with a threaded hole corresponding to the connecting hole and a mounting groove corresponding to the mounting part; in step S1.2, when the guide rail is installed, the mounting part of the guide rail is first inserted into the mounting groove transversely, then the connecting hole is aligned with the threaded hole, and a screw is locked to realize the installation and fixation of the guide rail and the stool surface. Such design enables the guide rail to be integrally formed independently of the stool surface. The guide rail arranged at the bottom of the stool surface not only contributes to the aesthetics but also saves space. Meanwhile, the detachable design facilitates the replacement of the guide groove when it is worn out, effectively prolonging the service life of the folding stool.

[0016] As preferred, the guide rail comprises a guide rail body and an elastic clamping strip arranged at one end of the guide rail body. The elastic clamping strip is arranged along the thickness direction of the guide rail, and a deformation space for the elastic clamping strip is formed between the elastic clamping strip and the guide rail body. A fixed clamping strip is arranged at the relative position of the downward flange of the periphery of the stool surface and the elastic clamping strip. A fixed limiting protrusion is arranged at the head of the fixed clamping strip, and a movable limiting protrusion is arranged at the head of the elastic clamping strip. In step S1.2, when the guide rail is installed, the elastic clamping strip is arranged opposite to the fixed clamping strip. At this time, the rotating rod formed at the upper end of the ottoman leg is clamped into the space between the fixed clamping strip and the elastic clamping strip. When the ottoman leg is opened or closed, that is, when the rotating rod rotates forward and backward, the rotating rod will be clamped by the fixed limiting protrusion on the fixed clamping strip and the movable limiting protrusion on the elastic clamping strip to be limited from being disengaged. The matched design fixes the position of the ottoman leg, making the rotation of the ottoman leg more flexible, controllable, safe and effective, and avoiding the deformation of the connection between the bottom of the stool surface and the ottoman leg or the disengagement of the ottoman leg during use.

[0017] As preferred, the corner is formed at the upper end position of the transition connection between the straight guide groove and the arc-shaped guide groove. The arc-shaped guide groove is first inclined upward from the end of the straight groove to the highest point of itself, and then inclined downward from the highest point to the direction away from the straight groove. In step S2.2, when the guide rod passes through the corner and the wrist is loosened, the guide rod is limited to move in the backward direction, and the forward direction forms a trend of sliding along the arc-shaped guide groove. The existence of the corner limits the movement route of the short ottoman leg during the opening and closing of the folding stool, facilitating the user to operate the opening and closing of the folding stool.

[0018] As preferred, there is a position perpendicular to the stool surface during the rotation of the short ottoman leg. In the perpendicular position, the perpendicular line of the short ottoman leg perpendicular to the stool surface is taken as the boundary line between the straight guide groove and the arc-shaped guide groove, and the corner is located at the side of the perpendicular position close to the straight guide groove part. Taking the perpendicular line position as the boundary of the guide groove, after the folding stool is swung away by one hand, the guide rod slides through the corner of the guide groove along the inertia, so that it can directly top the upper end of the arc-shaped groove in the vertical state and then slide along the shape of the arc-shaped groove to the end of the guide groove, facilitating the user to operate with one hand.

[0019] As a preferred, the arc-shaped guide groove is a circular arc-shaped guide groove, which takes the pin shaft position of the long bench leg and the short bench leg as the center, and the length between the connecting pin and the guide rod is the radius of the circular arc-shaped guide groove. The shape of the circular arc-shaped groove is adapted to the movement trend of the short bench leg when the folding bench is opened and closed, which can reduce the friction of the guide groove on the guide rod when the guide rod moves forward, and reduce the resistance of the short bench leg when it is opened and closed.

[0020] As a preferred, the long bench leg is a square frame structure as a whole, and the rotating rod is located at the upper end of the long bench leg; the short bench leg is a U-shaped structure as a whole, and the guide rod is connected to the upper end of the U-shaped opening of the short bench leg. The design of the square frame structure ensures that the folding bench can be stably placed on the ground in the open state, the U-shaped structure of the short bench leg saves materials and is simple to manufacture, and the position of the rotating rod of the long bench leg and the position of the guide rod of the short bench leg are horizontally aligned, so that the movement trajectories of the two bench legs are staggered, ensuring the smooth opening and closing of the folding bench.

[0021] As a preferred, when the folding bench is in the storage state, the short bench leg and the long bench leg are aligned in the longitudinal plane, and the short bench leg is located in the enclosed area of the long bench leg. From the side angle, the long bench leg and the short bench leg are on the same straight line, so that the folding bench is finally stored in the shape of a nearly flat cuboid, the space occupied by the storage is small, and it can adapt to various special storage situations such as narrow gaps and bed bottoms.

[0022] The principles and beneficial effects of the invention using the above technical scheme are:

[0023] The application provides a configuration method for single-handed operation of a folding bench. A guide rod is arranged at the upper end of a short bench leg, a guide groove matched with the guide rod of the short bench leg is arranged on a guide rail, the guide rod of the short bench leg can move forward and backward in the guide groove, the guide groove is arranged in two sections by changing the shape of the guide groove on the guide rail, the front section is a straight-line guide groove, and the rear section is an arc-shaped groove. Since the movement trend of the guide rod of the short bench leg in the guide groove is arc-shaped when the bench legs are opened and closed, the movement of the guide rod of the short bench leg in the arc-shaped groove is smoother and the restriction is smaller than the movement in the straight-line guide groove. An angle is formed at the transition connection between the straight-line guide groove and the arc-shaped groove. When the guide rod crosses the angle, it cannot move backward due to the obstruction of the angle, thereby forming a trend of continuing to slide along the arc-shaped groove. When a user opens the folding bench with one hand, the guide rod of the short bench leg can directly pass through the angle from the end of the straight-line guide groove and continue to slide along the shape of the arc-shaped groove to the end of the guide groove, thereby realizing automatic opening of the folding bench. When the folding bench is folded with one hand, the guide rod of the short bench leg can also directly move backward along the arc-shaped groove to pass through the angle and then smoothly move into the straight-line guide groove, thereby achieving control of the opening and closing direction of the folding bench with one hand.

However, it will be recognized by one skilled in the art that the present application can be practiced without the specific details and, therefore, the scope of the present application is not limited to the details disclosed herein.

[0039] The detailed description of the present application is as follows:

[0040] As shown in the figure, the present application provides a configuration method of a single-hand operation folding stool, which comprises the following steps: Figures 1-12

[0041] I. Configuration and assembly of folding stool:

[0042] S1.1, as shown in the figure, prefabricate guide rail 5, set guide groove 7 with the size matched with guide rod 13 on guide rail 5, divide guide groove 7 into communicating linear guide groove 71 and arc guide groove 72, and form corner 6 at the joint of linear guide groove 71 and arc guide groove; Figures 6-7 S1.2, as shown in the figure, install stool leg, wherein the stool leg is divided into long stool leg 2 and short stool leg 3, the upper end of short stool leg 3 is previously connected with guide rod 13, first insert guide rod 13 into guide groove 7 of guide rail 5, then install guide rail 5 at the bottom of stool surface 1 to complete the installation of short stool leg 3; preset the upper end of long stool leg 2 and the bottom of stool surface 1, the upper end of long stool leg 2 is part of rotating rod 11, and the bottom of stool surface 1 is rotatingly connected, wherein hollow handle 4 is also set on stool surface 1, and the handle 4 and linear guide groove 71 are close to the rotating position of the upper end of long stool leg 2, and pin 8 is punched at the intersection of long stool leg 2 and short stool leg 3 to realize the rotating connection between them;

[0043] Figure 3 II. Use of folding stool:

[0044]

[0045] S2.1, as shown in the figure, open folding stool in storage state, in storage state, long stool leg 2 and short stool leg 3 overlap together, and stool surface 1 is in vertical and drooping state; when opening, the user holds handle 4 with hand, and opens stool surface 1 by wrist force, then long stool leg 2 rotates due to inertia, and guide rod 13 at the upper end of short stool leg 3 slides forward from the first end of guide groove 7 in guide rail 5, at this time, since stool surface 1 is upturned, guide rod 13 of short stool leg 3 always moves along the bottom of the first section of guide groove 7, i.e. linear guide groove 71; when guide rod 13 moves through corner 6, guide rod 13 comes to the joint position of linear guide groove 71 and arc guide groove 72, at this time, the wrist is released and no longer exerts force; Figure 8 S2.2, as shown in the figure, use folding stool, in use state, long stool leg 2 and short stool leg 3 are in parallel and horizontal state, and stool surface 1 is in horizontal state;

[0046] Figure 8 ​​​​As shown, after the folding stool is placed on the ground, the guide rod 13 will be attached to the top of the arc-shaped guide groove 72 under the influence of the gravity of the stool top 1 and the gravity of the stool leg, and will continue to slide along the shape of the arc-shaped guide groove 72 spontaneously, and finally reach the end of the guide groove 7, realizing the complete opening of the folding stool, and achieving the purpose of single-handed operation.

[0047] Specifically, as shown in Figure 2 or Figure 4 or Figure 5 As shown, the corner 6 is located at the transition connection between the straight guide groove 71 and the arc-shaped guide groove 72, and the specific position is at the upper end of the transition connection. Since the stool top 1 is in a vertical state when it is stored, and is in a horizontal state when it is opened, the stool top 1 performs an upward turning movement when it is opened. During this process, the guide rod 13 first moves in the straight guide groove 71 pressing the lower end of the straight guide groove 71, and then moves after the corner 6, pressing the upper end of the arc-shaped guide groove 72. Therefore, the existence of the corner 6 limits the backward movement route during the opening and closing of the folding stool leg, facilitating the user to perform the opening and closing operation of the folding stool with one hand.

[0048] As shown in Figures 6-8 One end of the guide rail 5 is provided with a connecting hole 12, the other end of the guide rail 5 is provided with a mounting portion 14, and the bottom of the stool top 1 is provided with a threaded hole 16 corresponding to the connecting hole 12 and a mounting groove 15 corresponding to the mounting portion 14. In step S1.2, when the guide rail 5 is installed, the mounting portion 14 of the guide rail 5 is first inserted into the mounting groove 15 transversely, then the connecting hole 12 is aligned with the threaded hole 16, and a screw is locked to realize the installation and fixation of the guide rail 5 and the stool top 1, so that the guide rail 5 can be independently integrally formed with the stool top 1. The guide rail 5 arranged at the bottom of the stool top 1 not only contributes to the aesthetics, but also saves space. Meanwhile, the detachable design facilitates timely replacement when the guide groove 7 is worn out later, effectively prolonging the service life of the folding stool.

[0049] Further, as shown in Figure 3 or Figure 5 The guide rail 5 installed at the bottom of the stool top 11 includes a guide rail body 51 and an elastic clamping strip 10 arranged at one end of the guide rail body 51. There is a space between the elastic clamping strip 10 and the guide rail body 5 for the elastic clamping strip 10 to deform under stress. A fixed clamping strip 9 is arranged at the bottom of the stool top 1. The fixed clamping strip 9 is integrally formed with the stool top 1. Specifically, the fixed clamping strip 9 is arranged at the inside position of the downward turned flange at the edge of the stool top 1.

[0050] When the guide rail 5 is installed, the elastic clamping strip 10 is arranged opposite to the fixed clamping strip 9, the elastic clamping strip 10 is arranged on the top end of the guide rail 5 close to the handle 4, the head of the fixed clamping strip 9 is provided with a fixed limiting protrusion 91, the head of the elastic clamping strip 10 is provided with a movable limiting protrusion 101, the rotating rod of the bench leg 2 is rotationally connected with the bottom of the bench surface 1, specifically, the rotating rod is clamped into the gap between the fixed clamping strip 9 and the elastic clamping strip 10, when the bench leg is opened and closed, that is, when the rotating rod rotates forward and backward, the rotating rod is clamped by the fixed limiting protrusion 91 on the fixed clamping strip 9 and the movable limiting protrusion 101 on the elastic clamping strip 10, the rotating rod is limited by the fixed clamping strip 9 and is fixed at the bottom of the bench surface 1, so that the bench leg 2 only rotates at the fixed position, and because of the existence of the elastic clamping strip 10, the rotating rod has a squeezing space for rotation, so that the rotation of the bench leg 2 is more flexible, controllable, safe and effective, and the deformation of the bench surface 1 and the falling of the bench leg 2 in the use process are avoided.

[0051] More specifically, as shown in Figures 6-7 The corner 6 is formed at the upper end position of the transition connection between the straight guide groove 71 and the arc-shaped guide groove 72, the arc-shaped guide groove 72 is first inclined upward from the end of the straight guide groove 71 to the highest point of itself, and then inclined downward from the highest point to the direction away from the straight guide groove 71; in step S2.2, when the guide rod 13 passes through the corner 6 and the wrist is loosened, the guide rod 13 is limited to move in the backward direction, and the forward direction forms a trend of sliding along the arc-shaped guide groove 72. The existence of the corner 6 limits the movement route of the short bench leg 3 in the folding and unfolding process of the folding bench, which facilitates the user to operate the folding and unfolding of the folding bench.

[0052] At the same time, as shown in Figure 4 During the rotation of the short bench leg 3, there is a position perpendicular to the bench surface 1, and at this vertical position, the vertical line of the short bench leg 3 perpendicular to the bench surface 1 is taken as the boundary line between the straight guide groove 71 and the arc-shaped guide groove 72, and the corner 6 is located at the side of the vertical position close to the straight guide groove 71. Taking the vertical line position as the boundary of the guide groove 7, after the folding bench is thrown away by one hand, the guide rod 13 slides through the corner 6 of the guide groove 7 according to inertia, so that it can directly top the upper end of the arc-shaped guide groove 72 in the vertical state and then slide along the shape of the arc-shaped guide groove 72 to the end of the guide groove 7, which facilitates the user to operate by one hand.

[0053] Further, as shown in Figure 5 The rear section of the guide groove 7, that is, the arc-shaped guide groove 72, is preferably a circular arc-shaped guide groove, the circular arc-shaped guide groove takes the position between the connecting pin and the guide rod 13 as the center, and the length between the connecting pin and the guide rod 13 is the radius of the circular arc-shaped guide groove. The shape of the circular arc-shaped groove 72 is adapted to the movement trend of the short bench leg 3 in the folding and unfolding process of the folding bench, which can reduce the friction force of the guide groove 7 on the guide rod 13 when the guide rod 13 moves forward, and reduce the resistance of the short bench leg 3 in the folding and unfolding process.

[0054] As shown in Figure 3 , as shown in Figures 1-4 , the long bench leg 2 is a square frame structure as a whole, and the rotating rod 11 is located at the upper end of the long bench leg 2; the short bench leg 3 is a U-shaped structure as a whole, and the guide rod 13 is connected to the upper end of the U-shaped opening of the short bench leg 3. The square frame structure design ensures that the folding stool can be stably placed on the ground in the open state, the U-shaped structure of the short bench leg 3 saves materials and is simple to manufacture, and the position of the rotating rod 11 and the position of the guide rod 13 are horizontally aligned, so that the motion trajectories of the two bench legs are staggered, ensuring the smooth opening and closing of the folding stool.

[0055] Further, as shown in Figure 1 , when the folding stool is in the storage state, the short bench leg 3 is aligned with the long bench leg 2 in the longitudinal plane, and the short bench leg 3 is in the enclosed area of the long bench leg 2. From the side angle, the long bench leg 2 and the short bench leg 3 are on the same straight line, so that the folding stool is finally stored in the shape of a nearly flat cuboid, occupying a small space, which can adapt to various special storage situations such as narrow gaps and bed bottoms.

[0056] At the same time, considering the different effects of different shapes of the guide groove 7 of the folding stool, the differences in the forces borne by the guide rod 13 in the linear guide groove and the arc-shaped guide groove are compared, as shown in Figure 10 , it can be found that for the linear guide groove, the pressure borne by the support point of the guide rod 13 and the guide groove 7 can be decomposed into the force F1 along the lower end of the bench leg downward and the force F2 along the horizontal direction of the guide groove 7, and the force arm L2B of the force F2 along the horizontal direction of the guide groove 7 is the distance from the rotation point of the bench leg hinge to the vertical direction of the bench surface 1; and for the arc-shaped guide groove, as shown in Figure 11 , the pressure borne by the support point of the guide rod 13 and the guide groove 7 can be decomposed into the force F1 along the lower end of the bench leg downward and the force F2 perpendicular to the direction of the bench leg, and the force arm L2A of the force F2 perpendicular to the direction of the bench leg is the distance from the rotation point of the bench leg hinge to the guide rod 13; obviously, L2A is longer than L2B, and for the decomposed F2 in the two cases, the moment of the force borne by the guide rod 13 in the arc-shaped guide groove is larger, so that under the same size, the arc-shaped guide groove is more likely to cause the guide rod 13 to slide to a farther position.

[0057] In summary, as shown in Figure 12As shown, the configuration and use method of the single-hand operation folding stool of the present application, by setting the front section of the bottom guide groove 7 of the stool top 1 as a straight guide groove 71 and the rear section as an arc-shaped guide groove 72, when the user opens the folding stool with one hand, the guide rod 13 of the short stool leg 3 can directly pass the corner 6 from the end of the straight guide groove 71 to the front under the influence of the gravity of the stool top 1, and continue to reach the end of the guide groove 7 along the shape of the arc-shaped guide groove 72, thus realizing the automatic opening of the folding stool. When the folding stool is folded with one hand, the guide rod 13 of the short stool leg 3 can also directly move along the arc-shaped guide groove 72 to pass the corner 6 by inertia, and instead of falling back to the arc-shaped guide groove 72, it smoothly moves into the straight guide groove 71, thus achieving the control of the opening and closing direction of the folding stool with one hand.

[0058] The above describes the present application and its embodiments in a schematic manner, which is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the purpose of the present application, similar structural modes and embodiments can be designed without creativity, which shall all belong to the protection scope of the present application.

Claims

1. A method for configuring a folding stool for single-handed operation, characterized by: First, configure and assemble the folding stool: S1.1, a prefabricated guide rail, wherein the guide rail is provided with a guide groove, the guide groove being divided into a connected straight guide groove and an arc guide groove, and forming a corner at the junction of the straight guide groove and the arc guide groove; the corner is formed at the upper end of the transition connection between the straight guide groove and the arc guide groove, and the arc guide groove first extends obliquely upward from the end of the straight groove to its highest point, and then extends obliquely downward from the highest point in a direction away from the straight groove; S1.2, Install the stool legs, which are divided into long stool legs and short stool legs. The upper end of the short stool legs is pre-connected with a guide rod. First, insert the guide rod into the guide groove of the guide rail, and then install the guide rail on the bottom of the stool surface to complete the installation of the short stool legs. Rotate the upper end of the long stool legs to the preset position at the bottom of the stool surface. The stool surface is also provided with a hollow handle. The handle and the straight guide groove are located near the rotation position of the upper end of the long stool legs. A pin is driven into the intersection of the long stool legs and the short stool legs to realize the rotational connection between the two. Second, use a folding stool: S2.1, when the folding stool is in its stowed state, the long and short legs overlap and the seat is vertically hanging down. When opening, the user holds the handle and uses wrist force to flip the seat outward. Due to inertia, the long legs rotate, and the guide rod at the top of the short legs slides forward from the beginning of the guide groove in the guide rail. At this time, because the seat is upturned, the guide rod of the short legs moves along the front part of the guide groove, that is, the bottom of the straight guide groove.
