Technical field

The utility model relates in general at least a portion by the structure that plastics constitute, and relates in particular to the furniture that can comprise molded plastic part, for example desk and chair.

Background technology

There are many dissimilar desks to be used to multiple different purpose as everyone knows.For example, conventional desk can comprise pivoting and be connected to the leg of desktop, and leg can be mobile between the folding memory location that is adjacent to desktop of outward extending use location and leg from desktop at leg.Conventional desk with relatively large desktop and folding leg is commonly called " banquet table ", and these desks usually in the auditorium, other places of banquet hall, conference centre, hotel, school, church and great number of people's party use.The desk of these types often has various structure and under various configurations, uses.When no longer needing banquet table, table leg can move to the memory location and desk can move or store more easily.

Because most of banquet table length are between 6 to 10 feet, width is between 3 to 4 feet, even therefore leg is in the folding position, the required storage area of this desk is also quite big.Big like this storage area is problematic for commercial location or mechanism (for example hotel, school and church), because must the considerable this desk of storage.

Conventional desk often comprises the desktop of being processed by various materials (for example timber, particieboard or metal).Yet, often heavier relatively by timber, particieboard or metal desktop, and this can make desk heavy or be difficult to move.By timber or metal desktop cost is also higher relatively and this desktop generally must obtain handling or polishing before using.For example, process desktop by timber and generally must obtain sand milling and colouring, and the metal desktop must be formed required form and obtain colouring.In addition, because these are wooden heavier relatively with the metal desktop, the cost that therefore can increase the desk transportation and transport.The weight of desktop makes desk be difficult to more move and storage.

In order to reduce the weight of conventional desk, desktop can be processed by the material (for example plastics) of relative lightweight.Disadvantageously be that the desktop of being processed by light material can need big stiffener or other structure members (for example support, support, supporting member, or the like) to strengthen desktop.Although these optional features can increase the intensity of desktop, optional feature also can increase the weight of desk.These optional features can cause the time assembling desk that manufacturing cost increases and needs are extra.In addition, securing member that need be extra is with these component-assembled and be connected on the desk time and manual work that this also need be extra in manufacture process.Optional feature and securing member can further increase the cost of desk and make desk be difficult to more make.And these optional features and securing member have possibility injury user's the leg or the sharp edges of arm.

Conventional desk can comprise the framework that links to each other with desktop.Framework can comprise an offside hurdle that utilizes securing member to link to each other with the desktop side.The power that needs a plurality of securing members that framework and desktop are fixedly linked and will be applied to desktop is delivered to framework.Unfavorable is that when on some existing desks, applying relatively large load or power, framework is understood bending, is out of shape and/or separated with desktop.In addition, being used for connecting frame possibly separate or break away to the securing member of desktop with desktop.If load or power surpass certain value, securing member even can damage and tear desktop.In addition, the framework of some existing desks or the securing member folding that under some situation, can collapse.

If relatively large load or power are applied on the part of desktop, the desktop of some existing desks also possibly take place not hope the bending that occurs or be out of shape.For example, if load or power are applied to the outer part of conventional desktop, then that part of desktop possibly take place not hope to occur moves or crooked.Particularly, that part of desktop maybe downwards when load or power are applied to the upper surface of desktop.

The large scale of conventional banquet table needs manufacturer, retailer and consumer that a large amount of memory spaces is provided.And a large amount of memory spaces especially individual problem for manufacturer, retailer and the consumer of the demand that storage is arranged, transport and/or display many desks.

Summary of the invention

Therefore need provide a kind of desk to overcome or alleviate above-mentioned defective and problem.

On the one hand, a kind of desk can comprise desktop and one or more leg, and said leg size is suitable for and is formed at surface (for example floor or ground) top supporting desktop.This desk can also comprise framework and the leg that links to each other with framework.These legs can move between folding or memory location and extension or use location with respect to desktop.Particularly, these legs can pivot between the outward extending extended position from desktop at the folding position and the leg of the contiguous at least desktop lower surface arrangement of leg.If desired, when leg was in the folding position, leg can at least partly contact or in abutting connection with the lower surface of desktop.In addition, the lower surface of desktop can comprise one or more recesses, and its size is suitable for and is formed at least a portion of holding leg when leg is in the folding position.Advantageously, can reduce to store and/or transport the required space of desk like this.

On the other hand, a kind of desk is lightweight relatively, can make desk transport more easily and move like this.For example, desk can include the lightweight table top that helps reduce the desk gross weight.Desk can also be made up of parts few in number or assembly, can reduce the weight of desk like this.In addition, need securing member few in number to assemble desk, so also can reduce the weight of desk.These securing members few in number can also make desk obtain assembling fast and easily.

On the other hand, a kind of desk can comprise the desktop that is made of plastics.For example, desktop can adopt blowing, injection moulding, rotary molding or other suitable molding processes to process by molded plastics.The molded plastics desktop can provide relatively hard and high strength structure, can bear using and wear and tear repeatedly like this.The manufacturing of molded plastics desktop also relatively fast, easily and efficiently.In addition, the molded plastics desktop can easily be molded as required size and dimension, for example general table, bidge table, personal table etc.The molded plastics desktop is lightweight relatively, for example because it can be included in the hollow that forms in the molding process.The molded plastics desktop can also comprise two relative walls of constant substantially at interval and/or preset distance, can help to improve the strength and stiffness of desktop like this.In addition, the molded plastics desktop generally can have weatherability and to temperature-insensitive.In addition, the molded plastics desktop can burn in the duration get rusty or other deteriorations takes place, and can help to form durable desk like this.

On the other hand, a kind of desktop can by molded plastics process and one or more characteristic integrally formed in molding process as the part of whole Construction integration.For example, the molded plastics desktop can comprise that one or more recesses (also being called as " the recessed portion (tack-offs) of closing ") and these recesses can be designed and be positioned to improve the intensity of desktop and/or make the isolated wall interconnection of desktop.These recesses can also size be suitable for and be configured to define the structure with special characteristics and quality, and for example desktop has substantially intensity, rigidity and/or structural intergrity uniformly.The molded plastics desktop can also comprise other characteristics, for example improves the structure of intensity, rigidity and/or the torsion resistance of at least a portion of desktop.

On the other hand, a kind of desk can comprise the parts that can access quick and convenient manufacturing.For example, the manufacturing on the side hurdle of leg and/or framework can be simple relatively.In addition, the side hurdle of leg and/or framework can connect on the table fast and easily, can reduce manufacturing cost like this.Desk can also only be made up of few parts and need securing member few in number, and desk can be assembled by manufacturer, retailer and/or consumer fast and easily.

On the other hand, a kind of desk can be so that the stacking of a plurality of desks.Advantageously, the configuration that the desk that stacks can be arranged to align.For example, a desk can align with adjacent tables at an easy rate, is convenient to transportation, storage and/or the display of a plurality of desks like this.Importantly, the desk of alignment can be in transportation, storage or state such as display and vertical, level or become suitable angle layout according to for example desk.If desired, the desk that stacks can interlocking or is had the tendency that keeps together.For example, frictional fit or interference engagement can tend to make desk to keep being in stacking configuration between the desk of adjacent one another.If desk has the tendency that keeps together, then this can help to reduce in transportation, storage and/or the display process damage to desk.

On the other hand, a kind of desk can be nested with adjacent tables to reduce occupation space.Importantly, nested desk makes these desks can be stored in littler area, can significantly reduce storage and cost of transportation like this.Nested desk can also with the conventional desk area identical that does not nest together under the storage greater number desk.In addition, nested desk can help to protect desk to avoid damaging.For example, because the top of a desk can be arranged within the bottom of adjacent tables, therefore can help to prevent that desk is damaged.Nested desk also can have desktop identical with conventional desk or substantially the same size, can show that these desks can have similar in appearance and characteristic to the consumer like this, for example intensity, structural intergrity or the like.Nested desk can also have the footprints identical with conventional desk, but nested desk obviously can have more desk to be arranged on the tray or in the container, and/or can have the desk of equal number to be arranged in the obviously littler space.

On the other hand, a kind of desk can nestedly with adjacent tables be in and stack configuration.Advantageously, nested desk is compared the height that can have obvious reduction with the conventional desk that does not nest together.For example, existing desk can have highly the height that can stack at least 63.75 inches for about 2.125 inches desktop and 30 existing like this desks.The illustrative embodiments of nested desk can have the about 2.0 inches desktop of thickness, but can be with adjacent tables overlapping about 0.25 inch, makes the height of overlapped section of nested desk be merely about 1.75 inches.Therefore, the height of 30 nested desks is reduced to about 52.75 inches, because adjacent tables can nest together.Particularly since the part of desk can be arranged in the adjacent tables or with the overlapping nested arrangement that is in of adjacent tables, therefore the total height of nested desk is reduced.Therefore, in this representative configuration, the height that is in the desk of nested arrangement can be merely about 1.75 inches.Thereby existing desk reduces about 0.375 inch to 0.25 inch before the aspect ratio of each nested desk.Can there be more desks to arrange to be in like this and stack configuration, thereby greatly increase the quantity that can overlay on tray or the shelf or be arranged in the desk in container or the truck.

On the other hand, a kind of desk can nest together the total height that stacks desk with reduction with adjacent tables.For example, conventional desk can have highly about 2.0 inches blow molded plastic desktop and highly about 1.625 inches framework.The desk that the height of the framework of this conventional desk has desirable strength and rigidity greater than 80% of height of table top with formation.The framework that is used for this conventional desk can have rectangular cross sectional configuration, and helping to use at interval substantially like this, two relative walls of constant distance form girder structures.Be known that the reduction that reduces to cause desk intensity of frame height.It is also known that frame width reduce can cause desk that distortion and/or the bending that occurs takes place not hope.Compare with these existing desks, framework makes nested desk can have total height and the outward appearance identical with conventional desk, and overall strength and the structural intergrity identical with conventional desk, but desk can be nested together.The consumer is inferred immediately, and nested desk has overall strength, rigidity and the torsion resistance identical with conventional desk, because these desks can have identical substantially size and footprints.Yet the framework of nested desk has obviously reduced two or more height that stack desk.Because nested desk can have significantly reduced height under nested arrangement, therefore can save considerable space, this point is extremely important to manufacturer in manufacturing and transportation; Extremely important to the retailer when storing or displaying a plurality of desk; And/or it is also extremely important to the consumer who buys, transports or store a plurality of desks.

On the other hand, a kind of desk can size be suitable for and be configured to nestedly with at least one other desk, makes the height of nested desk reduce and surpasses 10%.For example, the height of single desk can be about 2.0 inches.When desk was nested with other desks, this desk was only contributed about 1.75 inches height, because the part of desk nests together.In this embodiment, the nested desk height that causes each to stack desk reduces about 0.25 inch.Therefore, the aspect ratio that is in the desk that stacks configuration is in that non-to stack configuration little by about 12.5%.Advantageously, make desk can obtain storage more efficiently, transport and display like this, because need littler space.In another embodiment, standard pallet or transport configuration can comprise 21 conventional desks, but the disclosed desk with nested characteristic of this paper can allow 27 or 29 desks to be arranged on the standard pallet or in the typical transport configuration.If arrange 27 rather than 21 desks on tray or in the standard transport configuration, then can store more, transport or display roughly 28% desk.If arrange 29 rather than 21 desks on tray or in the standard transport configuration, can realize that then desk quantity improves 38%.Advantageously, this can cause significantly saving and cost advantage, because for example can under equal area, store, transport or display obviously more desk; Or at the desk of to 25% area when young, storing, transport or display equal number.When a large amount of desks for example obtains transporting in standard or high power capacity container, can cause greatly saving cost and have cost advantage.

On the other hand, a kind of desk can be nested with adjacent tables, makes the height of nested desk reduce roughly 20%.For example, the height of conventional blow molded plastic desktop is normally 2.0 inches or bigger.The height of table top of nested desk is about 2.0 inches when it is not nested with another desk, but the height of desk overlapped section is merely about 1.5 inches to 1.75 inches when nested with another desk.Cause like this when two or more desks nest together, highly significant reduces by 12.5% to 25%.Particularly, about 20% if nested table height reduces, then these desks can have about 1.6 inches height when being in nested arrangement.In addition, nested desk can have the weight less than the conventional desk of contrast.Therefore nested desk can stack more nested desk like this stacking with one or more other desks or can contributing littler weight when nested under the situation that does not increase additional weight.
