Description

a folding cabinet

technical field

The invention relates to a furniture product, in particular to a novel cabinet.

Background technique

Although household cabinets on the market have complete functions, their basic structures are fixed. Therefore, whether it is in use or not, its footprint is the same. In recent years, although some foreign designers have developed a variety of foldable cabinets with beautiful appearance and novel opening methods, on the one hand, these cabinets occupy a small area when they are closed, and on the other hand, they will Stretching in multiple directions, its practicality is limited in many places where the space is really cramped.

On the other hand, as people's living conditions change, a certain number of small-area residential occupants (such as long-term rental houses, small hotel-style apartments, commercial and residential lofts, etc.) The occupied indoor area is equivalent to idle. Imagine a cabinet that can provide the function of a complete kitchen when in use, and free up most of the space for other uses when not in use. Such products are undoubtedly helpful for improving space utilization in small-area living occasions.

Furthermore, the reason why the industrialization of construction has become the focus of the industry is that it achieves the goals of improving quality, reducing costs and shortening the on-site construction period at the same time through large-scale centralized production. Traditional custom-made cabinets include many links such as on-site measurement, functional design, custom-made processing, and on-site installation. In particular, measurement and installation must be performed on-site by professionally trained personnel. Its cost will inevitably increase with the increase in labor costs, and the entire ordering cycle is also difficult to shorten due to the serial work of each link, and product quality is also difficult to control due to manual operations and small production scale.

Contents of the invention

The purpose of the present invention is to provide a folding cabinet that is easy to standardize and produce, which can be unfolded when in use, and can be folded and closed when not in use, so as to reduce space occupation.

To achieve the above object, the present invention adopts the following technical solutions:

A folding cabinet, comprising a side panel, a back panel, a first door panel and a second door panel; the side panel and the back panel are fixed by a set of corner brackets and a kitchen table; between the back panel and the first door panel, the first A plurality of hinges are used to connect the door panel and the second door panel, so that the first door panel and the second door panel can be opened and closed.

In the folding cabinet, a cabinet body is fixedly installed on the second door panel, and a set of casters is installed on the lower end of the cabinet body.

This forms the basic structure of the folding cabinet. the result is:

1. The continuous opening and closing of the first door panel and the second door panel can free up a relatively complete space for other purposes in the closed state of the folding cabinet when it is not in use;

2. The combination of the cabinet body, casters and the second door panel makes the folding cabinet have stable support no matter when it is opened or closed;

3. In the use/expanded state, make the folding cabinet have two relatively stable platforms (including the kitchen table installed on the side panel and the back panel and the upper end surface of the cabinet body supported by casters) for installing kitchen utensils that need long-term load bearing (such as stoves, water basins).

Furthermore, the structural features of the folding cabinet of the present invention also include:

In the folding cabinet, an operating table is installed on the first door panel through a hinge, and a foldable support frame is provided under the operating table, so that the operating table can be turned up to the level when in use and is borne by the support frame. Load-bearing; and in the recovery state and when the support frame is folded, the operating platform can be turned down to be vertical and close to the first door panel.

In the folding cabinet, choose one of the following structures:

a) When the kitchen utensil table is used to install the stove, install the water basin on the upper end of the cabinet; correspondingly, install the hood on the back panel and above the stove;

b) When the kitchen table is used to install the water basin, the cooker is installed on the upper end of the cabinet; correspondingly, the hood is installed on the second door panel and is located above the cooker.

In the folding cabinet, the outer side wall of the backboard has a concave structure, which is used for the connection of the water and electricity pipelines inside the folding cabinet and the pre-buried part of the building.

This forms the functional structure of the folding cabinet. The overall cabinet needs to have cooking functions, washing functions, operating functions and storage functions, and each function needs to be realized by corresponding devices.

The two platforms in the basic structure are used to install the stove and the water basin respectively, not only because the stove (for cooking) and the water basin (for washing) each represent a set of functions, but also because they have important functions in use. Load requirements, such as placing pots with ingredients on the stove, washing utensils and water, etc. More importantly, both need to be equipped with pipe network connections, such as upper and lower water pipes, power supply lines and even smoke pipes, and these pipe networks need to be relatively fixed at least at their first and last ends.

In contrast, although the operating table also has load-bearing requirements when it is in use, because it does not need to connect pipelines, it can be designed in a folded style to reduce the space occupied in the recycled state.

Regardless of whether a) or b) is selected, the hood should be installed above the stove to achieve its maximum efficiency, while the basket and hanger for storage can be placed in the empty space.

As for the concave structure of the back panel, although it is not involved in the use of the cabinet, it leaves space for the building to be embedded and provides convenience for on-site installation, so it should be regarded as an assembly function structure.

The present invention is further designed as follows: a storage board is installed on the side board through a hinge, and the storage board is formed by connecting the first storage board and the second storage board through an intermediate bracket; a hook is fixed on the second storage board; When the storage board is laid flat, the hook installed on the second storage board is hung on the supporting frame for load bearing; when the storage board is folded, the first storage board and the second storage board are folded and close to the side panels.

In order to realize the supporting and locking functions more safely and reliably, the present invention is designed as follows: a groove plate is fixed on the support frame; In the groove of the board, the support frame can not only support the second storage board, but also realize the locking of the support state of the support frame at the same time. Further explanation: the groove plate has a trapezoidal groove with a wide top and a narrow bottom. The arc groove, when it is hung on the groove plate, its left and right shaking is also restricted; at the same time, the hook is a vertical surface relative to the far end of the second storage board, and its twisting freedom is also restricted when it is close to the groove plate, so as to realize The overall locking of the support frame by the hook is achieved. The near end of the hook relative to the second storage board is an inclined plane, which is convenient for taking off and hanging.

In the folding cabinet, several baskets and hangers are installed for placing various kitchen articles. For example, baskets for holding dishes, baskets for storing dry goods and seasonings, as well as chopstick holders, knife holders, shovel hangers, pot lid holders, etc. This type of device will be installed in multiples according to the specific purpose, and the shape and size are different; the principle is to install it on the side panel, back panel, first door panel and/or second door panel.

In the above part of the functional structure, the devices corresponding to the cooking function, washing function and operation function of the cabinet have been described. It is one of the characteristics of the present invention to achieve different storage functions from conventional cabinets. An overview of structural features and storage features can be summarized as:

Compared with conventional cabinets, there is only one group of cabinets in the structure of the present invention, and the storage volume is very small. In order to accommodate more items, it is necessary to install storage baskets and hangers on the upper half of the basic structure.

In the closed/recovered state, the storage space inside the cabinet must be fully utilized, while in the unfolded/applied state, it is necessary to consider leaving room for the operator to move. Therefore, the depth of the basket hanging on the wall panels (comprising side panels, back panels and each door panel) should be small, but the combination of each basket in the recovered state should take up as much space as possible.

When the cabinet is in the unfolded/applied state, the overall volume becomes larger. Supplementing the storage space in the form of a storage board will bring great convenience to practical applications.

The present invention utilizes the above-mentioned structure to realize the dual demands of complete application functions in the unfolded state and small occupied area in the recycled state. In the face of market segmentation with occasional use characteristics, the cabinets manufactured by the present invention are easy to standardize production under the premise of standardized product models, and all can be completed in the manufacturing plant, without the need for designers to come to measure, and can also be installed by themselves . Figuratively speaking, you can buy cabinets like buying refrigerators.

The advantages of the present invention are:

1. It has novel structure, strong practicability and complete functions. Although it is small in size, it can realize the main or even all functions of conventional cabinets, which is very helpful to improve the utilization rate of space in small-area living occasions;

2. When in the folded state, it can be enclosed in a refrigerator-like shape, which not only occupies a small space, but also facilitates transportation and storage during sales;

3. The form can be diversified, and the door opening direction can be established according to local conditions through the active connection of the door panel, so that it is more practical;

4. When the cabinet is in the unfolded/used state, supplementing the storage space in the form of a storage board will bring great convenience to practical application.

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

Referring to Fig. 1, it depicts the unfolded/applied state of the cabinet of the present invention. Wherein: the side plate 1 and the back plate 2 are fixed into a triangular support with screws through the corner code 13 and the kitchen utensil table 6. Corner code 13 can be provided with a plurality of as required, no matter the side of kitchen range top 6 is one side close to side plate 1 or one side close to back plate 2, all can be screwed in multiple places. This group of structures forms the installation main body of the cabinet. When the side panel 1 or the back panel 2 is close to the wall, at least one side should be directly fixed to the wall. This improves the stability of the cabinet on the one hand, so that the kitchen utensil table (cooker is installed in this embodiment) has a certain load-bearing capacity; The smoke exhaust pipe) must be fixed on the back panel, so as to ensure that the pipeline will not be affected when the cabinet is opened and closed.

Referring to FIG. 4 , the lower part of the backboard 2 is concave up to the ground structure. In this way, the water and electricity pipelines inside the cabinet can be connected in advance by the hose, and the connection with the embedded part of the building can be arranged outside the product. In order to keep the finished size of the product unaffected, a concave back is an effective option.

Returning to Fig. 1, the first door panel 3 and the second door panel 4 are respectively connected by hinges (wherein the first door panel 3 is connected with the back panel 2 through the hinge, and the second door panel is connected with the first door panel through the hinge), so that It is possible for the main structure of the cabinet to be recyclable from the fully expanded state in Figure 1 to the non-use fully closed state (see Figure 3 for the style of the closed state).

In order to ensure the stability of the cabinet in the process of opening and in the fully opened state, the second door panel 4 in this state requires supports other than the lower edge of the panel surface. Therefore, the cabinet body 11 is installed on the second door panel 4 , and casters 16 are installed at the lower end of the cabinet body 11 . This not only ensures that the cabinet body has full support on the bottom surface in the expanded/used state, but also makes the movement process smoother. In this embodiment, the water basin 10 is installed on the cabinet body 11 because of such considerations: in the unfolded state, the side of the backboard 2 and the side of the second door panel 4 have good support conditions, and correspondingly, the load will be relatively heavy. Big part (cooking range top and water basin) is installed on these two plates, and the first door panel 3 in the middle then only bears the load of lighter, shorter time.

The console 9 installed on the first door panel 3 is designed to be folded in order to reduce space occupation in the closed/recovered state and to be effectively supported in the unfolded/used state. Correspondingly, the storage board (the first storage board 7 and the second storage board 8) also adopts the same approach.

Figure 2 is the transition between the cabinet from the unfolded/used state to the closed/recovered state. The operating table 9 is fixed on the first door panel 3 by the hinge 14, which not only specifies its movement mode, but also plays the role of rear end load bearing; the support frame 17, which plays the role of front support, can be folded to make it Fit within the width of the console. The storage board is also installed on the side panel 1 by the hinge 14, and the first storage board 7 and the second storage board 8 are folded by the hinge-like effect of the middle bracket 15 when in the recovered state.

As can be seen from Fig. 1 and Fig. 2, the width and thickness of the cabinet body 11 are obviously smaller than the space enclosed by the side panels, the back panels, and the first and second door panels, and the left, front and right sides are above-mentioned in the closed state. There is a certain gap between each structural plate. Among them, the gap on the left (between the cabinet body 11 and the side panel 1) is used to place the folded storage board in the recovered state; the gap in the front is used to avoid the concave part on the back panel 2; Between the body 11 and the first door panel 3) is used to accommodate the folded console. See Figure 3 for the state of the entire cabinet after it is fully closed/recovered.

As can be seen from Fig. 1, under the expanded state, the first storage board 7 has been effectively supported under the double action of the hinge 14 and the middle bracket 15, but although one end of the second storage board 8 is supported by the middle bracket 15, the other end is It needs to be hung on the support frame 17 of the operating table through the hook 18. This embodiment innovatively adopts the requirement that one group of structures simultaneously support two groups of flaps.

In order to more safely and reliably realize the support for two groups of flaps, the present invention is designed with: a grooved plate 20 is fixed on the support frame 17; Hanging in the trapezoidal groove of the groove plate can not only make the support frame take into account the support of the second storage board, but also realize the locking of the supporting state of the support frame. Further explanation: Referring to Fig. 5 to Fig. 7, the groove plate 20 has a trapezoidal groove with a wide top and a narrow bottom. Shaking is limited; the top of the hook is an arc groove (as shown in Figure 6), and when it is hung on the groove plate, its left and right shaking is also limited; while the far end of the hook relative to the second storage board 8 is a vertical surface of the hook In 1801, the degree of freedom of torsion is also limited when it is attached to the groove plate, so that the overall locking of the support frame by the hook is realized. The near end of the hook relative to the second storage board is a hook slope 1802, which is convenient for taking off and hanging.

The fact that the hood 5 is mounted on the back panel 2 is an example (both visible in Figures 1 and 2). It has shown the idea that although the cabinet product of the present invention is small in size, it is ready to fully realize all the functions of the conventional cabinet. Cooperate with the stove that is installed on the kitchen utensil table 6 in the present embodiment, the supporting equipment of cooking function is complete; Water basin is installed on the cabinet body 11, and faucet, upper and lower water pipes are installed on it (because do not relate to the technical point of the present invention so Not shown in the figure), then the washing function is also complete; the console 9 installed on the first door panel 3 can be used for placing objects under the cooperation of the support frame 17, and can be used for operations such as cutting vegetables; and the storage function Partly, pots and other relatively large single-piece utensils can be placed in the cabinet, and baskets and hangers 19 are installed on the side panels and door panels above the surface of the stove (for the sake of description, number 19 only points to the largest The baskets. The circular and square baskets installed on the first door panel and the bottomless baskets installed on the side panels, which are not marked but visible in the illustration, are all baskets for placing different items) placing bowls Chopsticks, spices, knives, spoons and other basic necessities. In this embodiment, in the manufacture of the prototype, it is even designed to place the items that are not suitable for loading into the basket on the cooker and between the baskets in the recovered state, and then transfer these items to the storage board in the unfolded state (for example: rice cooker ). Under the premise that all the above functions are realized, the actual closed size of this embodiment is only 598mm×598mm×1970mm. To put it figuratively, the folding cabinet can only occupy the area of a tile in the closed state (the standard 600X600 tile has an area of 0.36 square meters).

The above-mentioned embodiments can be changed without departing from the scope of the present invention. Therefore, the structures included in the above description and shown in the drawings should be regarded as illustrative rather than limiting the protection scope of the present invention.

It should be added that although the technology and sales market covered by the present invention are only a part of household cabinets, they represent a product development concept. The products formed under the guidance of this concept are of course not limited to cabinets, but products with the same concept and system will definitely generate more value in combined applications.
