Multifunctional chair with telescopic expansion table frame

Abstract

A multifunctional chair with a telescopic expansion table frame is characterized in that the multifunctional chair comprises telescopic parts, slot modules and a chair base body, the telescopic parts are telescopic sliding rails and are installed below armrests of the chair base body, the telescopic parts are used for expanding a table frame area when a telescopic rod stretches out and restoring the basic original appearance of the armrests of the chair base body when the telescopic rod retracts backwards, and the slot modules are groove modules. The slot modules are arranged above the front end of the telescopic rod of the telescopic piece and above the slot opening of the telescopic piece respectively, the slot openings of the slot modules are opposite to each other to form a sliding groove capable of being inserted into the table plate and limiting the table plate from being separated, and the seat base body is of a seat base body structure and has the functions of supporting the human body and installing the components. Compared with the prior art, the seat has the difference and innovation points that the structure is simple and not abrupt, and the original symmetrical and simple structural appearance of the seat is not influenced by excessive exposed parts, so that the seat can be applied to function expansion use of various types of seats.

Description

Technical Field

[0001] The present invention relates to tables and chairs, and in particular to a telescopic and expandable table frame multi-functional chair. Background Art

[0002] Tables and chairs are indispensable items in people's lives. Compared with traditional tables and chairs, multi-functional tables and chairs have the advantages of reducing the floor area for use and manufacturing costs. The disadvantage is that for existing multi-functional tables and chairs, due to the addition of assembled table or chair components, multiple supporting components are installed and suspended on the seat base. In terms of visual perception, its structure has defects such as complexity and inconvenience in use. For example, in prior arts with application numbers (CN201010247459.3), (CN201210292851.9), (CN201510073948.4), etc., the structure is a side-rotatable multi-functional integrated table and chair composed of a support rod, a connecting rod, a rotating shaft, and a tray installed on one side of the seat base. Although the use function of the tabletop is expanded, the added components for supporting the tabletop make the overall seat appear abrupt and asymmetrical in appearance, and the use experience is not smooth and flexible enough. Therefore, multi-functional, integrated, and expandable tables and chairs sold on the market have not been recognized and accepted by most consumers due to the above-mentioned deficiencies. Summary of the Invention

[0003] The purpose of the present invention is to provide a telescopic and expandable table frame multi-functional chair and a usage method to solve the problems and deficiencies described in the above background art. To achieve the above purpose, the present invention provides the following technical solution: A telescopic and expandable table frame multi-functional chair, characterized in that it includes: a telescopic member, a slot module, and a seat base. The telescopic member is a telescopic slide rail installed under the armrest of the seat base. Its function is that when the telescopic rod extends, a table frame area is expanded, and when it retracts, the original appearance of the armrest of the seat base is restored. The slot module is a groove module installed above the front end of the telescopic rod of the telescopic member and above the slot opening of the telescopic member respectively. Its function is that the groove openings of the slot module form a sliding slot capable of inserting a tabletop relatively and restrict the tabletop from coming out. The seat base is a seat base structure, and its function is to support the human body and install the above components.

[0004] The present invention further provides a usage method for a telescopic and expandable table frame multi-functional chair, characterized in that when in use, the user extends the telescopic members at the left and right armrests to expand a chute area where a tabletop can be inserted and insert the tabletop to use. When the user needs to leave temporarily, the user can slide the tabletop to the side and then get up and leave. When resetting is required, the tabletop in the chute is slid out to the side, and then the telescopic members are retracted to the original position at the armrests to restore the original appearance, and the function of resetting the seat can be completed.

[0005] The differences and innovative points of the present invention compared with the prior art are that its structure is concise and not obtrusive, and there are no excessive exposed components affecting the original symmetrical and simple structural appearance of the seat, so it can be applied to the functional expansion of various types of seats.

[0006] BRIEF DESCRIPTION OF THE DRAWINGS: The drawings illustrate exemplary embodiments disclosed by the present invention and, together with the description thereof, are used to explain the principles of the present invention. These drawings are included to provide a further understanding of the disclosure of the present invention, and the drawings are included in this specification and form a part of this specification of the present invention.

[0010] SPECIFIC EMBODIMENT: Next, the technical solutions in the embodiments of the present invention will be clearly and detailedly described in conjunction with the drawings in the embodiments of the present application.

[0011] As shown in Figure (1), a multi-functional chair with a telescopic and expandable table frame, characterized in that it includes: a telescopic member 1, a slot module 2, and a seat base 3. The telescopic member 1 is a telescopic slide rail and is installed under the armrest of the seat base 3. The slot module 2 is a groove module and is respectively installed above the front end of the telescopic rod of the telescopic member 1 and above the slot opening of the telescopic member 1. The seat base 3 is a seat base structure.

[0012] As shown in Figure (2), the present invention further provides a method for using a multi-functional chair with a telescopic and expandable table frame. When in use, the user extends the telescopic members 1 at the left and right armrests to expand a chute area where a table board can be inserted and inserts the table board for use. When the user needs to leave temporarily, the user can slide the table board sideways and then get up and leave. When resetting is required, the user slides the table board in the chute out sideways, and then retracts the telescopic members 1 to the original position at the armrests to restore the original appearance, thus completing the function of resetting the seat.

[0013] As used in the specification, examples and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and the claims do not use the difference in names as a way to distinguish components, but rather use the difference in the functions of components as the criterion for distinction. As used throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". Those skilled in the art can solve the technical problems within a certain error range and basically achieve the technical effects.

[0014] The above description has illustrated and described embodiments of the present invention. However, as mentioned above, it should be understood that the present invention is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in related fields. And any modifications and changes made by those skilled in the art without departing from the concept and scope of the present invention should fall within the protection scope of the appended claims of the present invention.
