Technical Field

The invention relates to a furniture support leg adaptive to a ground environment, belonging to the technical field of indoor furniture and outdoor furniture.

Background

At present, the connection between the bed feet and the bed stile (also called bed adding and bed listening, the two sides of the bed surface are fixedly connected through a bed bar, and the bed bar is also called a bed cross) of the sleeping bed for daily life is fixedly and hard connected, and because the lower ends of a plurality of bed feet of one bed can not be completely contacted with the ground due to the processing error between the bed feet and the incomplete flatness of the ground, the bed foot pad with a gap between the bed feet and the ground is often arranged by adopting pieces with different thicknesses. In order to solve the problems of processing errors among the bed feet and incomplete leveling of the ground, a floor-falling bed appears in the market, the lower surface of a stile of the floor-falling bed is directly contacted with the ground and adopts an integral bearing mode, and the problems of processing errors among the feet and incomplete leveling of the ground are basically solved; however, because the ground under the bed is completely covered by the stile of the floor-falling bed, the moisture under the bed can not be volatilized, so that the bed feels very cold when sleeping on the bed in cold seasons. Moreover, the conventional bed cannot adjust the inclination of the bed surface according to the most comfortable prone position of the user.

The seats on the market at present comprise a three-leg seat, a single-leg seat and a four-leg seat, and also comprise a five-leg seat and a six-leg seat, wherein the seats can be lifted or lowered. The liftable seats are mainly single-leg liftable seats, and there are also multi-leg liftable seats. Firstly, a single-foot lifting seat (I) adopts a rotating gear to unidirectionally stir a rack on a support inner column to slide upwards, locks the rotating gear by a tongue tooth and does not rotate so as to ensure that the support inner column does not slide downwards to lift, and adopts a mode that the tongue tooth leaves the rotating gear to ensure that an automatic gear rotates so as to ensure that the support inner column descends; secondly, a hydraulic cylinder is driven to extend by adopting an artificial hydraulic pump or an electric hydraulic pump, and the pressure is relieved by adopting a back pressure screw to reduce; and thirdly, the screw rod is matched with the threaded sleeve, and the chair leg is extended and shortened by rotating the screw rod. The multi-leg lifting seat (I) adopts a sliding sleeve type, forms a sleeve type fit in a manner that an inner sleeve is embedded in an outer sleeve, extends by pulling the outer sleeve and the inner sleeve, shortens by pushing the outer sleeve to move towards the inner sleeve, and locks the length of the extended or shortened chair leg by inserting a bayonet lock into a bayonet hole without changing; the fixed sleeving type is adopted, the chair legs are extended by sleeving the fixed outer sleeve at the lower end of the fixed inner sleeve, and the chair legs are shortened by detaching the outer sleeve; and thirdly, the screw rod is matched with the threaded sleeve, and the chair leg is extended and shortened by rotating the screw rod. However, the extension and contraction of the legs of these chairs do not satisfy the requirement that the chair is stably placed on a slope or uneven ground inclined in the field, nor does the chair adjust the inclination angle and the sitting posture of the chair according to the sitting posture preferred by the user.

Along with the progress and development of society, people who love leisure life in the field are more and more, a stable and practical bed is required to be placed on the ground which is suitable for inclination and the rugged ground firstly when people sleep comfortably in the field, and a stable and practical seat is required to be placed on the ground which is suitable for inclination and the rugged ground firstly when people sleep comfortably in the field; however, the heights of the four feet of the traditional bed and chair are fixed and unchanged, and the height of the bed stile cannot be changed at all to adapt to the inclined ground and the uneven ground; therefore, conventional beds and chairs cannot be used for field rest and leisure life at all.

With the progress of society and the demand for enjoyment of living things becoming higher and higher, people have increasingly high demands for the comfort of beds for sleeping and for the comfort of leisure seats. As the heights of the four feet of the prior bed for sleeping are fixed, in order to meet the comfort requirement of a person, the height of the bed is partially increased to realize the high-low inclination of the bed so as to meet the sleeping comfort of the person; the height of the four legs of the seat is fixed, so that in order to meet the requirement of comfort of a user, the height of the bed is partially increased to meet the requirement of comfortable sitting posture of the user; however, after some of the bed legs are padded up or are padded up higher than some of the chair legs, the bed legs are not perpendicular to the bed frame and generate an inclination, so that the bed legs are easily broken at the connection part with the bed frame to easily cause safety accidents, and the chair legs are not perpendicular to the seat frame and generate an inclination, so that the chair legs are easily broken at the connection part with the seat frame to easily cause safety accidents.

In order to enable the support legs of the furniture to adapt to different ground implementation, a plurality of college students and schoolmates design the furniture support legs which can enable the support legs to extend and compress randomly and shorten randomly, can lock the length of the extended and shortened support legs rapidly, can be placed on inclined ground and uneven ground and can be stably implemented on the ground environment in a self-adaptive mode through long-term research.

As a teacher of college student schoolmates, witnessed the final success of several college students from the research of complex technical structures to the simplest of technical structures, and after passing through the research and development process of being indiscriminate and endurable for three years, the process is also what is commonly called a big to brief process; the university teacher who has studied more than thirty years of time as a conversion of effort is well aware of that it is not difficult to study a complex technical structure, and it is difficult to change the complex technical structure into a simple technical structure, and only the complex technical structure is changed into a simple technical structure, which can be really great way to simple, so that students who have innovation ability and research and development ability in the teaching life of the life are happy and luxurious.

The following is explained: the two technical schemes of the sloping field stable dining table and the furniture support leg adaptive to the ground environment are jointly developed by several college students, the prior dressing of the pit in the furniture factory is more expensive, and the project developed by several college students when the friends of the college students see the dressing of the college students is competitive and developmental, so that the research and development cost is negotiated with the students of several college students; aims to produce stable dining tables on sloping fields and furniture supporting legs adaptive to the ground environment by adopting the technology of funding by a plurality of people represented by Tan Ming Gui and dating by a plurality of students and leading to the technology of marketing, thereby realizing the common entrepreneurship; originally, the capital of several people and the school friends of college students mean that two technical schemes are put into a patent for protection, so that the application cost of the patent and the protection cost of the patent are reduced. However, at the time of writing with the help of a teacher (not charged for a fee) who teaches a patent to a university, the teacher thinks: although the two patents of the furniture support leg for the stable dining table on the sloping field and the furniture support leg adaptive to the ground environment are related to each other in technology, the two patents belong to the technical field of furniture, the height of the two patents is adjusted by using a telescopic cylinder as a basis to extend and shorten the leg, and the length of the two patents is locked by a hydraulic switch; however, firstly, the table top of the table is required to be horizontal on the sloping field, secondly, the furniture support legs adaptive to the ground environment can be inclined in any direction to enable a user to feel the most comfortable sitting posture or lying posture, and the inclination of the table surface can be adjusted according to the sitting posture or lying posture of the user, so that the connection structures of the legs are different, in addition, the table legs of the table on the sloping field need to be locked at different angles, the furniture support legs adaptive to the ground environment need to be changed in connection angle, so that the support legs are upright, and the support legs are matched with the folding frame bodies on the support legs; resulting in: the protection schemes of various technical structures are not well described in a unified way in the patent claims, and from the singularity of patent protection, even if the technical schemes of the slope smooth dining table, the slope leisure seat and the furniture leg adaptive to the ground environment are placed in a patent, the claimed claims are not unique; therefore, two patent applications of furniture legs for stable dining on sloping fields and self-adapting to ground environments must be written to ensure that the requirements for the uniqueness of the claims are met.

Because two patents are formed, the application rights of the patents are negotiated and signed a cooperation agreement of technical admission, and the garden represents a plurality of college student alumni for application; at the time of filing the patent application, several payers and several college student schoolmates have already done the prior work of production and are protected against patent grants.
