Description

Technical Field

[0001] The utility model relates to the technical field of household articles, in particular to a stool. Background Art

[0002] A Ma Zha is a common household item and a small piece of seating. It is widely used in daily life because of its light weight and foldability.

[0003] A stool usually includes two cross-arranged and hinged leg frames, each of which has an upper crossbeam. The stool also includes a seat, and the front and rear sides of the seat are respectively connected to the upper crossbeams on the two leg frames. When the two leg frames are spread out, the seat is unfolded for people to sit on; when the two leg frames are closed together, the volume can be reduced for easy carrying.

[0004] A Chinese utility model patent document with the authorization announcement number CN204318079U discloses a stool, the upper crossbeam of which is made of steel pipe, and copper plugs are welded on both ends of the crossbeam. The disadvantages of this stool are: 1. Since the upper crossbeam cylinder is cylindrical, there is no fulcrum on the two upper crossbeams when the stool is folded, and it is difficult to grab it with one hand, which is inconvenient to use; 2. When the stool is unfolded for use, the four corners of the top surface of the stool are easy to touch the legs, causing harm to the user. Therefore, in view of these problems, it is necessary to further improve and optimize the structure of the stool. Summary of the invention

[0005] The utility model aims to provide a stool to solve the problems in the prior art that after the stool is folded, the upper crossbeam lacks a fulcrum and is inconvenient to grasp with one hand, and the four corners of the top surface of the stool are easy to touch the legs when in use.

[0006] In order to achieve the above-mentioned purpose, the utility model discloses a stool, comprising a first leg frame and a second leg frame which are cross-arranged and hinged together, the first leg frame and the second leg frame both comprising an upper crossbeam, the stool also comprising a seat surface made of a flexible material, a seat surface connection mechanism is provided between the first side edge of the seat surface and the upper crossbeam of the first leg frame, and between the second side edge of the seat surface and the upper crossbeam of the second leg frame, a holding groove is provided on the outer side surface of the upper crossbeam, and a first rounded corner is provided at the portion where the end face, the upper surface and the outer side face of the upper crossbeam meet. After the first leg frame and the second leg frame are brought together, the thumb and the other four fingers can be buckled in the holding grooves on the two upper crossbeams respectively, so as to facilitate the single-handed grasping of the stool, and the first rounded corner makes the four corners of the top surface of the stool no longer sharp, effectively solving the problem that the four corners of the top surface of the stool are easy to touch the legs, and the use is more comfortable.

[0007] Furthermore, the first leg frame and the second leg frame both include a lower crossbeam, and the end face, lower surface, and outer side of the lower crossbeam are connected to a second rounded corner. The second rounded corner effectively solves the problem that the four corners of the bottom surface of the stool are easy to touch the feet, making it more comfortable to use.

[0008] Furthermore, the upper surfaces of the upper cross beam and the lower cross beam are both curved surfaces with a circular arc cross-section. Through the above improvements, when a person sits on the folding stool, the front and rear sides of the folding stool are smooth and have no sharp corners, so there will be no discomfort on the buttocks. At the same time, the top surface of the lower cross beam also adopts a curved surface design without sharp edges, so it will not rub or touch the feet, ensuring the comfort of use.

[0009] Furthermore, both the first leg frame and the second leg frame include a lower cross beam, and two left and right support rods connecting the upper cross beam and the lower cross beam. The two support rods of the first leg frame are located between the two support rods of the second leg frame. An interval column is provided between the two support rods of the first leg frame. Threaded holes are provided at both ends of the interval column, and studs are screwed at both threaded holes. Both studs sequentially pass through the support rods of the first leg frame and the second leg frame and extend outwards. Nuts are screwed on the outer extending ends of both studs. The studs passing through the support rods of the first leg frame and the second leg frame achieve the hinge connection between the two; the interval column connects the two studs into a whole, ensuring that the two hinge joints remain coaxial; the nuts not only have the functions of decoration and protection, but also can adjust the tightness of the connection between the first leg frame and the second leg frame.

[0010] Furthermore, a spacer sleeve is sleeved on the stud, and the spacer sleeve is located between the interval column and the support rod of the first leg frame. By replacing spacer sleeves of different lengths, the requirements for different designed spacings of the support rods of the first leg frame can be met.

[0011] Furthermore, the inner hole on the spacer sleeve is a threaded hole, and the spacer sleeve is screwed on the stud through this threaded hole. By rotating the spacer sleeve, the clamping degree between it and the nut can be adjusted, thereby further adjusting the tightness of the connection between the support rod of the first leg frame and the support rod of the second leg frame.

[0012] Furthermore, a first gasket and a second gasket are sleeved on the stud. The first gasket is located between the spacer sleeve and the support rod of the first leg frame, and the second gasket is located between the nut and the support rod of the second leg frame. The first gasket and the second gasket have the functions of decoration and protecting the support rods.

[0013] Preferably, the seat surface connection mechanism includes a plurality of buckle rings arranged at the edge of the seat surface, and also includes a fixing rope passing through each buckle ring. A plurality of threading holes are arranged at intervals along the length direction of the upper cross beam. Spacing blocks are formed between the threading holes. An interval gap is jointly formed by adjacent buckle rings, the seat surface and the fixing rope. The spacing block is located in the interval gap. In this way, in addition to arranging threading holes on the upper cross beam, a stable connection between the seat surface and the upper cross beam can be achieved without other complex structures or additional components. This design has a simple structure and low manufacturing cost.

[0014] Further, a first groove for accommodating a fixing rope is provided on the outer side surface of the upper crossbeam, and a second groove for accommodating the edge of the seat surface is provided on the inner side surface of the upper crossbeam. The design of the first groove and the second groove enables the fixing rope and the edge of the seat surface to be properly accommodated, which not only improves the aesthetics but also effectively avoids the wear of these two parts.

[0015] Preferably, the seat surface connection mechanism includes a plurality of buckles provided at the edge of the seat surface, and further includes a blocking rod passing through each buckle. A third groove is provided on the outer side surface of the upper crossbeam, and two clamping blocks facing up and down are provided in the third groove. Card slots are provided on both clamping blocks, and the card slots on the two clamping blocks together form a cavity for accommodating the blocking rod. A fourth groove for accommodating the edge of the seat surface is provided on the inner side surface of the upper crossbeam, and the fourth groove penetrates the bottom of the third groove. Compared with the previous method of fixing with a fixing rope, this solution omits the complex steps of passing the fixing rope through each threading hole and connecting it to the buckle during assembly, making the operation more convenient.

[0016] In summary, the beneficial effects of the present utility model are as follows: The folding stool provided by the present utility model embodies a user-friendly design and is relatively comfortable to use; at the same time, the folding stool provided by the present utility model can be grasped with one hand and is relatively convenient to carry; in addition, the folding stool provided by the present utility model is also relatively simple to manufacture and assemble, improving the production efficiency.
