Description

Improvement on the Structure of Symmetrical Chair Legs

Technical field:

The utility model relates to an improvement of the structure of a symmetrical chair foot group, in particular to a chair which can form a beautiful symmetrical arc state regardless of the unfolded or folded state.

Background technique:

In addition to taking into account the so-called convenience and practicality, the design of various products nowadays, due to the appreciation of visual senses, makes all kinds of household furniture products tend to be beautiful designs with multiple colors or complex lines without exception. Take the chair as an example. For the current foldable chair (as shown in Figure 1), the main structure of the chair is a back frame with armrests in each group on both sides, and a back frame that is pivotally connected with the aforementioned back frame. The seat frame and the front and rear chair feet at the appropriate places of the two armrests form a foldable chair, which can make the seat frame make a relative retraction movement towards the back frame, and simultaneously move the front and rear chair legs, That is to say, the front and rear chair feet are in a corresponding folded state (as shown in Figure 2), the purpose is to greatly reduce the space occupied by the chair after being folded and facilitate placement and transportation. In terms of visual sensory enjoyment, the color part has to be dyed in front of each component. It is quite easy to form a multi-image design. However, in terms of line design, in order to greatly reduce the volume after folding, the previous 2. When the rear chair legs are in the folded state, the relative inner surfaces must be completely attached. Therefore, the front and rear chair legs of the above-mentioned chairs can only be designed as straight rod tubes. Other components that are relatively matched, such as seat frames, armrests, etc., It can only be a rigid design with a single straight line, and there is no aesthetic feeling at all. Therefore, at present, chairs with more beautiful lines are mostly non-foldable chairs, and the method is to use the armrests of the chairs, the front and rear chair legs, etc. The seat frame and the seat frame are properly bent and processed into various shapes, and then the components are welded or locked into shape. Since they cannot be folded, although they are aesthetically pleasing, they also have problems such as occupying display space.

Invention content:

The main purpose of the utility model is to solve the above-mentioned shortcomings and avoid the existence of the disadvantages. The utility model provides a foldable and aesthetically pleasing chair. The design concept of the present utility model is that the front and rear chair legs of the two chair legs set on the two sides of the seat frame to receive the seat frame to make the chair stand upright are in a symmetrical but non-upright curved shape. arc surface, and at the bottom of the front and rear chair feet, there is a foot pad to make up the angle formed by the front and rear chair feet and the ground, so that the chair can stand firmly on the ground with the help of the above foot pad when unfolded, and The front and rear chair legs of the chair are in a beautiful and symmetrical arc state in the unfolded and folded states, so as to achieve the dual benefits of both the convenience of folding and the visual beauty. In addition, the front and rear chair feet can be curved with different degrees of curvature relative to the inner surface; the relative armrest and seat cushion can be designed with the front and rear chair feet to form an undulating overall arc, which is in a closed state after being folded, and the overall appearance is consistent. Change the traditional monotonous straight line design.

Detailed ways:

The utility model further clarifies the characteristics and progress of the utility model through the following embodiments, but the utility model is by no means limited to the following embodiments. Please refer to Figs. 3 and 4, which are a schematic view of the three-dimensional appearance and a side view of the utility model. As shown in the figure: the chair leg group of the present utility model is made up of two groups of front and rear chair legs 4, 5 that are pivotally connected to the seat frame 1 two sides to accept the seat frame 1 and make the chair stand upright. The seat frame 1 includes a cushion portion 12 pivotally connected to the front and rear chair feet 4 and 5 middle positions, a back cushion portion 11 whose lower end is pivotally connected to the rear end of the aforementioned cushion portion 12, and a back cushion portion pivotally connected to the aforementioned back cushion. The armrests 13 on both sides of the part 11 and pivotally connected with the upper sections of the front and rear chair legs 4 and 5, wherein the opposite inner surfaces of the front and rear chair legs 4 and 5 are curved surfaces 42 that are symmetrical but not upright . The front and rear chair legs 4, 5 are integrally bent and formed, so that the chair can stand firmly on the ground with the help of the foot pads 41, 51 when unfolded, and the front and rear chair legs 4, 5 of the chair are in the unfolded and folded state They are all in a beautiful and symmetrical arc state.

As shown in Figures 4 and 5, it is a schematic diagram of the unfolded and folded state of the utility model. The rear chair foot 5 of the present utility model is provided with a sliding buckle 52 and a restricting member 522 in the displacement groove 521 provided on the sliding buckle 52, and a rear chair foot 5 is provided with a sliding buckle 52 in the aforementioned sliding Within the displacement range of the buckle 52, a tongue 531 is provided on it to limit the displacement of the sliding buckle 52. The positioning part 53, in order to make the chair unfold, the tongue 531 of the positioning part 53 can be positioned by means of the sliding buckle 52 to form a buckle state, so as to prevent improper folding of chairs. (the safety sliding buckle 52 member of chair is known technology).

From the 4th and 6th figures, we can clearly see the unfolded state of this creation. Since the bottom ends of the front and rear chair legs 4 and 5 are each provided with a foot pad 41 that compensates for the angle formed between the front and rear chair legs 4 and 5 and the ground , 51, and form reinforcement ribs 411, 511 on the bottom surface of the foot pads 41, 51 to prevent the chair from slipping, so that the front and rear chair feet 4, 5 can fully support the chair and the human body sitting on it Weight and can not produce the situation of deflection inclination, moreover, because front and back chair foot 4,5 are in the design of a curved surface 42,54 relative to the inner side (can have the curved surface of different waviness according to the beautiful design 42', 54' design, the relative front and rear chair legs are 4', 5', the foot pads at the bottom end are 41', 51' can also be designed with appropriate angles), the relative armrest 13 and seat cushion 12 can also be The front and rear chair feet 4 and 5 are designed with undulating curves to form an overall visual sense of the chair.

As shown in Figure 5, the sliding buckle 52 is first displaced upwards to break away from the tongue 531 of the positioning member 53, and then force is applied to the front end of the seat cushion portion 12 and the upper end of the back cushion portion 11 of the seat frame 1 to perform the folding action of the chair. When folding, the pivot joints of the above-mentioned components are used to fold together. When the folding is completed, it can be clearly seen that the relative inner sides of the front and rear chair legs 4, 5 are designed with relatively symmetrical curved surfaces 42, 54, so they can be folded when folded. Fully fit to effectively reduce the overall volume, and the armrest 13 and seat cushion 12 are also designed with the rear chair legs 4 and 5 as an overall radian design, so that the armrest 13 and seat cushion 12 are also in a close state after being folded, and the folded Afterwards, the overall appearance has changed from the traditional monotonous straight line design, and replaced it with a design based on the creation of beautiful curves. Thus, the dual benefits of both the convenience of folding and the visual aesthetics are achieved.
