Description

Combined design structure of containing space

Technical Field

The invention relates to the field of furniture products, in particular to a combined design structure of a containing space and a cabinet body or cabinet with the structure.

Background

In traditional furniture, a cabinet is a main product and has functions of storing, storing and placing articles. And therefore, the classification of cabinets in the field of furniture is not well defined. In many cases, the name or the classification of the cabinet is distinguished according to the storage function or the storage object. For example, a cabinet for storing clothes is called a wardrobe, and a cabinet for storing books is called a bookcase. There are also some classifications where the cabinets have other distinguishing functions, for example, cabinets that are easy to move are called event cabinets, display cabinets that highlight stored items, and so on.

In any case, the main function of the cabinet is "storage". The storage forms are various, and the arrangement of the various storage forms on the same cabinet not only needs to consider the integral aesthetic property, but also needs to rationalize the spatial arrangement.

Disclosure of Invention

The technical scheme of the invention is as follows: a combined design structure of a containing space is mainly embodied on space layout and structure combination.

The combined design structure comprises multifunctional unit plates, and specifically can be divided into a reference plate, a support plate, a partition plate, an outer plate and the like, and the basic space outline of the structure can be formed based on the various unit plates.

The datum plate comprises a top plate and a top plate, and plays a role in building and bearing the frame. And also determines the shape of the spatial profile based on the shape of the reference plate. The shape association of the reference plate with the spatial profile is of course not absolutely limited, but the present invention does not exclude the existence of a design solution in which the shape of the reference plate may differ from the cross section of the spatial profile, based on the structural preparation and the aesthetic appearance, preferably "the shape of the reference plate determines the appearance of the spatial profile".

The reference plate is taken as a base, specifically a top plate and an opposite bottom plate, and the top plate and the bottom plate are structurally arranged to form a plurality of directional outer vertical surfaces of a space profile. Bearing in mind the above technical point, the orientation of the facade may depend on the orientation of the side edges of the datum plate, although this is not a limitation.

Furthermore, if the space between the top plate and the bottom plate is defined as a unit, the possibility of overlapping combinations of the units in this form is not excluded.

In the frame arrangement forming the space profile described above, a support plate is required for supporting between the bottom plate and the top plate, which is then also characterized in that the support plate can completely divide the interior of the space profile into two types of regions. Namely a closed object placing area at one side of the supporting plate and an open object placing area at the other side of the supporting plate. Due to different storage forms, the two areas can complete storage functions through different structures.

Specifically, the top of the supporting plate is in contact with the top plate, the bottom of the supporting plate is in contact with the bottom plate, and the supporting plate serves as an interface to become a common plate for the closed object placing area and the open object placing area. Meanwhile, the common plate can be provided with different structures due to the orientation of the vertical face.

Because of the different storage forms, a plurality of storage units are arranged in the closed storage area, and the storage units are drawer-type storage boxes in the scheme. The main area (i.e., the storage area) in which the storage box is located in the closed storage area, or is covered with the reference plate. The outer side of the storage box is then the outer facade that forms the spatial profile at the enclosed storage area.

Further, if the outer contour and the size of the storage box match the inner contour and the size of the closed object region, the outer side surface of the storage box can be an outer vertical surface of the spatial contour without any accident. Thus, it is not excluded that there may be a mismatch of the two profile shapes.

Based on above-mentioned storage unit's the characteristics that set up, can have a plurality of receivers, the whole facade of closed thing district department space profile is constituteed to the lateral surface of a plurality of receivers under the principle that the structure extends.

Therefore, the arrangement relation of the storage units is considered, the arrangement and combination mode of the storage units is not limited, and the storage units can be changed according to design requirements and the concept of attractive appearance.

The open type object placing area is characterized in that: has an open carrying area and can directly place the open area of the article. Further design is a plurality of layers in this scheme, and every layer is separated by the partition panel and forms, and the partition panel is as the loading board of placing object article, and the loading board is regarded as by the bottom plate so bottom.

Specifically, each layer is provided with an outer plate, and the outer plates can be used as space profile vertical faces at the open type object placing areas. Likewise, the outer skin of the plurality of layers constitutes the entire facade of the spatial contour at the open cargo area, under the principle of structural extension.

In the scheme, in order to increase the design feeling and improve the use effect. The outer plate of each layer is provided with an opening, and through the opening, each layer can realize storage (not bearing) and can achieve the effect of direct taking and placing.

Based on the basic structure, the scheme is as follows:

the storage box is installed through the connecting pieces (the rotating shaft and the rebounders) positioned inside the closed object placing area, and the storage box can be moved out of the closed object placing area through the connecting pieces. It is the drawer structure of straight rail formula that is comparatively common, it can set up straight rail, spout or wheel components etc. on the inner wall in closed object region or the outer wall of receiver.

This aspect is preferably accommodated by a rotary shaft type drawer structure.

Specifically, a rotating shaft is arranged in the closed object placing area, the upper end of the rotating shaft is fixed on the top plate, and the lower end of the rotating shaft is fixed on the bottom plate. The receiver then passes through the bearing spare assembly in the pivot, and the receiver can follow the closed thing district that puts and move out with the rotation in the horizontal plane.

Further, the relative position of the rotating shaft on the accommodating box is an eccentric position at the side edge. The relative position of the rotating shaft in the closed object placing area is close to the edge of the space outline, so that a more ideal rotating opening and closing state can be formed.

The rotation of receiver is opened and shut and still needs the locking structure, and this locking structure can provide its trigger force that breaks away from the normal position simultaneously. Select in this scheme to use the bounce-back ware, each receiver then corresponds a bounce-back ware.

The direction of setting up of bounce-back ware is that the rotation direction according to the receiver corresponds, and the trigger end of bounce-back ware is used in on the receiver, and the opening direction of receiver is from closed thing district inside to closed thing district outside, therefore the direction of launching of the setting of bounce-back ware is rather than the same.

Further, the rebounder is fixed on the side wall of the supporting plate in the closed storage area through an assembly part, a groove for installing the rebounder is formed in the assembly part, the rebounder is connected in the groove through a fastening piece, and a cover plate is arranged outside the groove.

The receiver is rotating closed back, needs and the locking of bounce-back ware, consequently is provided with the n type catching groove that corresponds bounce-back ware trigger end on the receiver, and the height of n type catching groove is the same with the maximum height that bounce-back ware triggered the end, and when the trigger end of bounce-back ware pasted the receiver surface and upwards rotated and packed up, the trigger end can be followed receiver surface card and gone into in the n type catching groove to reach the purpose that the receiver rotated the locking. When the trigger end of the rebounder bounces to the outside, the trigger end rotates downwards, so that the trigger end is separated from the n-shaped buckle groove, and the storage box is unlocked.

Based on the rotation action of opening and shutting of receiver, then require to reserve a size in the sealed backup pad of putting in the district and dodge the district, and this size dodges the district and is used for coordinating the biggest movement track of receiver.

Because, if when the pivot sets up the apex angle position on the receiver, regard as the fulcrum with the pivot, the diagonal of receiver is the radius, "arm of force" overlength under this condition can cause huge burden, damage connection structure even to bearing of bearing piece and pivot. Therefore, the situation that the rotating shaft is embedded into the side edge of the storage box is avoided; under this structural design, can avoid above-mentioned problem to take place, nevertheless caused the change of the biggest motion trail of receiver, it dodges the district admittedly to have foretell size.

The structure of the open type object placing area needs to be simple and clear, and therefore, the shape of the open type object placing area needs to be concise. It is worth emphasizing that the combination of the cross-sectional shapes of the open type object placing area and the closed type object placing area in the same horizontal plane is the cross-sectional shape of the whole space profile. The support plate thus acts as a common elevation for both areas, and the shape of the support plate may also determine the general shape of both areas.

The open storage area may be divided into a plurality of layers, i.e., storage layers, and the plurality of storage layers are layered by a partition plate. The outer plate of each accommodating layer is the outer boundary of the open type object placing area, and the supporting plate is used as the inner boundary of the open type object placing area. It is emphasized that in order to increase the design feeling and the use experience feeling, a cloth is attached to the inner boundary of the open storage area, that is, the outer surface of the support plate in each storage layer.

Based on the arrangement idea of the structure, the arrangement mode is applied to the cabinet body or the cabinet:

a cabinet based on the structure is provided with two areas of open type storage and closed type storage. Furthermore, a metal plating rod is arranged in the closed object placing area as a rotating shaft; in view of the structural weight and manufacturing cost in this embodiment, the plated metal bar is preferably a small oxidation-treated metal aluminum pipe. The plastic rod sleeve is sleeved on the metal aluminum pipe, and the matching precision is improved through the plastic rod sleeve. The metal aluminum pipe is matched and installed with the bearing piece on each storage box through the plastic rod sleeve.

Simultaneously, for the cooperation sets up the bounce-back ware in closed putting the thing district, the n type that corresponds bounce-back ware trigger end has then been arranged to correspond on the receiver is buckled, and it can play certain locking effect when receiver closed position, breaks away from with bounce-back ware trigger end when the receiver is opened simultaneously.

The metal aluminum pipe is arranged from the top angle of the outer side edge of the storage box to 1/3 with the long side edge, preferably 1/3 of the outer side edge of the storage box. Because the interference of the rotation track of the storage box on the vertical surface of the support plate can be reduced to the maximum extent (namely the turning radius is the most reasonable); and the biggest turned angle that this position can be realized is 145 degrees, and the receiver can not increase for the biggest arm of force overlength and bear the weight of burden to the bearing spare again when obtaining the at utmost to open.

A cupboard based on above-mentioned structure, this cupboard possesses open and takes in two kinds of regions with closed. The open type object placing area is a separated layered structure, and the closed type object placing area is a rotating shaft drawer structure arranged in multiple layers. Furthermore, the bottom of the cabinet is provided with a plug-in universal wheel.

Specifically, the universal wheel includes shaft, wheel body, connecting rod. The wheel body rotates around a wheel shaft as a rotation center, and a vertical connecting rod is arranged on a shell of the wheel shaft and plays a role in vertical bearing or supporting. The universal wheel is characterized in that a wheel cap is arranged at the upper end of the connecting rod, the wheel cap is a bearing body, and the universal wheel plays a role in lifting. The wheel cap is provided with a raised cylindrical end which is in coaxial relation with the connecting rod. Generally, a mounting hole is formed in a bottom plate of the cabinet, a hole sleeve is arranged in the hole, a cylindrical end can be inserted into the hole sleeve, and the bottom plate is lifted on the wheel cap.

The invention has the advantages that:

1. this structure has changed traditional theory of accomodating, adopts novel layout design, with space maximize's rational utilization. Meanwhile, the unit structure can be automatically replaced according to the use requirement, and the multifunctional combined type shoe pad can adapt to the use crowds of different ages and habits.

2. The appearance of the structure has a design sense, and the plate and the metal fittings are independently designed material units, so that the structure has a new and new sense in visual sense.

3. Specifically, two different types of storage boxes/layers are designed on the structure and the cabinet body/cabinet of the structure, so that the storage space is expanded, and the storage mode is more diversified.

4. Specifically, the open layer of accomodating of L type of design can freely define the not co-altitude of the cabinet body according to the demand, and the department design has corresponding grafting structure to make it fixed about accomodating the layer, need not have metal connecting piece to realize.

as shown in fig. 1 and 2, it is a combination design structure of a receiving space.

The method specifically comprises the following steps: the top plate 1, the bottom plate 2 and the support plate 4 are three unit plates with different functions. The top plate 1 is opposite to the bottom plate 2, the bottom plate 2 is used as a carrier of the whole structure, and the top plate 1 is used as a capping. The two ends of the supporting plate 4 act on the top plate 1 and the bottom plate 2 respectively to form a middle support, thereby forming a basic frame arrangement. If the structure is extended between the top plate 1 and the bottom plate 2, the vertical faces of the structure can be formed, and the vertical faces can be formed to combine the upper top plate and the bottom plate to form the space outline of the foundation.

In this embodiment, since the top plate 1 and the bottom plate 2 are both square plates, the spatial profile of the structural profile has four vertical faces with different orientations. The scope of the invention also includes other contoured shapes of the structure, such as triangular cross-sections, or other polygonal cross-sections.

The support plate is L-shaped, so that the support plate 4 divides the interior of the space profile into a closed object placing area with a rectangular cross section and an open object placing area with an L-shaped cross section.

A plurality of storage boxes 6 are fitted in the closed storage area, and the storage boxes 6 have a rotation center, i.e., a metal aluminum pipe which is provided in the closed storage area and is subjected to a small oxidation treatment is preferably used as the metal aluminum pipe for the metal plating. Receiver 6 passes through bearing part suit on electroplated metal pole 7 to electroplated metal pole 7 is the rotation fulcrum, and the anticlockwise is opened to the ann of receiver.

In this embodiment, the shape of the enclosed object placing area is slightly larger than the placing space of the A4 paper specification, and some documents can be placed in the enclosed object placing area.

The open storage area is divided into three independent layers by partition boards, the partition boards are loading boards of each layer, oval openings are formed in the outer boards of each layer, and small scattered objects such as keys, purses and mobile phones can be conveniently stored.

Example 2:

as shown in fig. 1-3, it is a combination design structure of a receiving space.

Based on the spatial profile arrangement in the embodiment, a plurality of storage boxes 6 are fitted in the closed storage area, and the open storage area is divided into three independent layers by partition plates.

In this embodiment, receiver 6's combination mode can correspond with the layer in open object district of putting, can correspond every layer according to receiver 6 of the supporting multiple height specification of needs, can independently make up receiver 6. For example, in fig. 3, the bottom layer and the middle layer are stacked with two storage boxes 6 with middle height, and the top layer is stacked with three storage boxes 6 with small height.

Therefore, the independent combination mode can embody the innovation of the design concept, not only accords with different users, but also can meet various storage requirements.

Meanwhile, in the layer structure of the open type object placing area, a layer structure which is convenient to install is adopted in the embodiment. That is, each receiving layer 3 is prefabricated independently, and the upper surface and the lower surface of the receiving layer 3 are provided with notches or buckles for plugging, so that the corresponding buckles or notches are correspondingly arranged on the top wall and the bottom wall of the open type object placing area. Based on this structure, accomodate layer 3 and do not need the metal connecting piece just can install, be convenient for independently make up moreover equally.

Meanwhile, the cloth 11 is attached to the inner boundary of the open type storage area, namely the outer surface of the support plate in each storage layer, so that the design feeling and the use comfort can be improved.

Example 3:

as shown in fig. 4 to 6, it is a combination design structure of the accommodating space.

Based on the aforesaid closed storage district in the cooperation of putting a plurality of commentaries on classics suction box 6, receiver 6 passes through the installation of electroplated metal pole 7. The arrangement position of the plated metal bars 7 is based on their relative positions on the storage case 6 because the storage case 6 is substantially similar in shape to the closed storage area, or at least similar on the corresponding side of the outer vertical surface. Therefore, after the relative position of the plated metal bar 7 on the storage box is determined, the relative position thereof in the closed storage area is also substantially determined.

In this embodiment, the electroplated metal rod 7 is fitted in the accommodating box range, because if the electroplated metal rod is fitted outside the side edge of the accommodating box 6, the force arm is lengthened, and the damage of the corresponding bearing part is high. Therefore, the relative position of the plated metal rod 7 at the side of the storage box 6 is based on the vertex angle of the side to the 1/3 length of the size of the side, and the position 1/3 is preferred in the embodiment. After creative design and comprehensive comparison, use this position as the rotation fulcrum, the biggest rotation orbit of receiver is less to the structural influence, is considering behind factors such as arm of force length, bearing strength, accessory life simultaneously, and the angle of opening and shutting that this position can provide is ideal, and its biggest angle of opening and shutting is 145, can satisfy depositing or taking of most article.

Example 4:

as shown in fig. 6 and 7, a cabinet based on a combination design structure of a storage space is provided.

As shown in fig. 6, the closed storage area corresponding to the square storage box is also square, and in order to avoid the influence of the maximum rotation track of the storage box 6, a size avoiding area is formed in the support plate corresponding to the area which is square and sunken in the open storage area. An assembly part 9 of a prism body is vertically arranged at the inner angle of the size avoiding area, a plurality of grooves for mounting the rebounders 8 are distributed on the assembly part 9 from top to bottom, the rebounders 8 are fastened in the grooves, and cover plate protection is arranged outside the grooves. Each of the rebounders 8 corresponds to one of the storage boxes 6.

Because the direction of removal of the storage cassette 6 is performed from inside to outside of the closed device area. In this configuration, the triggering direction of the rebounders 8 is therefore also carried out from within the enclosed installation area to the outside. As shown in fig. 7, the trigger end of the rebounder 8 acts at the inside corner position of the storage box 6. As shown in fig. 8, an n-type catching groove 10 is formed at the top corner, and the trigger end of the rebounder 8 can be caught therein for locking.

Example 5:

as shown in fig. 8, it is a cabinet based on the combination design structure of the receiving space.

Based on the 4 embodiments, four universal wheels 5 are arranged at the bottom of the cabinet body. Each universal wheel is provided with a wheel cap 12. The wheel cap is a bearing part for lifting the cabinet body and is arranged on a connecting piece of the universal wheel. As shown in fig. 8, a circular wheel cap 12 is provided on the vertical connection member, and a raised cylindrical end is provided at the center of the wheel cap 12. The cylindrical end and the connecting piece are in coaxial relation, so that the stability of the center of gravity can be guaranteed.
