Description

A kind of solid desktop of jointless

Technical field

The present invention relates to the solid desktop of a kind of jointless in a kind of Furniture manufacture field, especially solid wood furniture.

Background technology

In Furniture manufacture field, when especially the high-grade solid wood furniture such as redwood, narra, rosewood is made, desktop normally many solid wood boards is spliced, and is also to form by structures to form such as tenons between panel and housing.Be subject to the impact of air aridity and temperature, solid wood board can produce and expands or shrink with environment.Lumber fibre is generally strip, lumber fibre water suction and dehydration, and meeting collapse more serious in the direction perpendicular to fiber, and the length of fiber changes not quite.Therefore, collapsing of solid wood material is normally directive, collapses degree more serious in the direction perpendicular to tree ring.If this, collapse control bad, only with joints such as pin, tenons, several points limited on contact-making surface are fixed, in the process collapsing, timber collapses produced internal stress can focus on these tie points, and the joint of sheet material and, seam crossing easily produces crack between sheet material, even can damage joint, cause solid wood furniture to disintegrate.

For overcoming this caused problem of phenomenon that collapses, carpenter adopts two kinds of methods to be controlled conventionally:

First method is on solid wood board surface, to coat one deck paint film or wax layer, and paint film or wax layer make sheet material and air insulated, reduce the intrusion of airborne moisture to solid wood board, reduces the degree collapsing.

Second method is between sheet material, and especially the panel of desktop and the seam crossing of housing, deliberately process or reserve one width in the gap of 3-5mm, and this gap is called expansion joint.In the structure of being explained in patent No. CN200620084752.1 " Wooden table top ", for controlling the pucker & bloat problem of solid-wood panels, between panel and housing, need to reserve expansion joint together.

Above-mentioned first method is for solid wood furniture, especially high-grade solid wood furniture, and the fragrance that timber itself has and sense of touch can be changed by paint film or wax layer, and people's that high-grade sheet material brings nice feeling is destroyed, can not embody due value.

Second method will certainly leave again at least 2 roads or 4 gaps, road on the table, and in furniture use procedure, easily shelter evil people and countenance evil practices in these gaps, and especially, when wiping desktop, rag can run up to dust and dirt etc. these places, gap, can affect the aesthetic feeling of furniture.

How manufacturing the solid desktop that does not stay expansion joint and can exempt from paint, is the difficult problem that woodworking is never resolved.

Summary of the invention

Technical problem to be solved by this invention is the defect that overcomes prior art, and a kind of table top set-ups of solid wood furniture is provided, jointless on desktop, feel is level and smooth, even and desktop exempt from paint or exempt to wax also can control well and collapse the destruction of phenomenon to table top set-ups.

The present invention addresses the above problem adopted technical scheme: a kind of solid desktop of jointless, comprise panel and housing, and uniform many raft shelves in housing, have dovetail groove under panel, and dovetail groove and raft shelves coordinate; On described raft shelves, be designed with dovetail groove projection, wherein dovetail groove projection has a side and housing out of plumb at least, described raft gear number amount is greater than 2, and dovetail groove projection on two adjacent raft shelves, the direction tilting is different, it is characterized in that: raft shelves two ends are provided with tenon, tenon embeds in frame, and fixes with pin; When described desktop is made, adopt the minimum aridity condition processing that makes land used.

In the middle of described raft shelves, have the eye of reperusing, reperuse through raft shelves, the tenon at the two ends of reperusing embeds in frame, and fixes with pin.

Described raft shelves, reperuse and panel, housing adopt identical material to make.

After described raft shelves and erecting of panel, dovetail groove adopts glue to be strengthened.

Compared with prior art, the invention solves the problem that the desktop of solid wood furniture of exempting from paint need to stay expansion joint.Between raft shelves and panel, adopted the oat tail groove structure tilting to connect, in the X of desktop and the direction of Y, be all completely fixed, especially in raft shelves direction, the pressure when dovetail groove of whole inclination can disperse solid wood board to expand, therefore internal stress is dispersed on the contact-making surface of whole dovetail groove, rather than limited several fixing points, and owing to adopting identical producing wood, whole desktop becomes the mutually same integral body of degrees of expansion.Even if desktop does not stay expansion joint, also there will not be cracking situation.

This patent discloses two kinds of raft mark structures, and the first structure be can't see the dovetail groove of inclination from desktop bottom, and table body is more attractive in appearance, and the relative the first structure of the second structure is saved material more, and handling ease.

Through reaching experimental verification more than a year, the solid desktop of this structure is being exempted under paint condition, and through spring, summer, autumn and winter, moist and dry environment, the cooperation on desktop between solid wood board is still very tight, and table body structure is solid, and effect is fine.

The specific embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are further described.

A solid desktop for jointless, desktop comprises panel 1, housing 2 and raft shelves 3, panel 1, housing 2 and raft shelves 3 all adopt the producing wood of unified material.

Raft shelves 3 are connected by oat tail groove structure with desktop 1, above raft shelves, process dovetail groove projection 31, and the bottom of panel processes dovetail groove with matching.The degree of depth of dovetail groove is the 50% proper of plate thickness.Dovetail groove has a side and frame out of plumb at least, retains the oblique angle between 70-85 degree.The two ends of raft shelves 3 are provided with tenon 32, and tenon embeds in frame.By pin 33, be fixedly connected with frame 1.Raft shelves have at least more than two, and between two raft shelves, spacing is controlled in the scope of 10cm-40cm best to controlling expansion joint effect.The dovetail groove direction of the inclination of adjacent raft shelves can not be identical.

According to the actual size of desktop, can increase the intensity of reperusing to strengthen desktop.Reperuse vertical with raft shelves.Add and can in the middle of raft shelves, process the hole 34 of reperusing man-hour.Reperuse through after raft shelves, the tenon structure at two ends is connected with pin 41 with frame.

When desktop is made, adopt the minimum aridity condition processing that makes land used, the environment that for example south is comparatively moist adopts minimum aridity 12, and the words that the environment of northern relatively dry is used, adopting the standard of aridity 8 to carry out pretreatment solid wood material, when furniture is used, is mainly the problem that overcomes expansion.

Add man-hour, if panel is spliced by many solid wood boards, need to fix and slot again in advance, guarantee that the dovetail groove projection on dovetail groove and raft shelves can coordinate closely.

As shown in Fig. 3, Fig. 6, Fig. 7, the raft shelves in embodiment mono-process on a rectangular solid wood bar, and dovetail groove projection below has still kept rectangle structure.Desktop after installation, looks up from bottom, the neat atmosphere of raft shelves, and structure is well-balanced, appearance looks elegant.

As Fig. 8, Fig. 9, shown in Figure 10, the raft shelves in embodiment bis-are driven dovetail groove and are made on the bevelled solid-wood of a tool, add like this man-hour more simple, and the waste of timber still less.But from bottom, look up, raft shelves tilt, and profile is attractive in appearance not.This structure is suitable for there is base plate by the situation of raft shelves sealing under desktop.

When the dovetail groove of raft shelves and panel is connected, available glue is coated in dovetail groove, and strengthening syndeton, makes the connection of raft shelves and panel tightr.Make on complete solid desktop, between the batten of splicing panel, and the gap of panel and frame is all very little, is all less than 1mm, and after desktop polishing operation, desktop is level and smooth, touches seamless sense.

Because adopting the oat tail groove structure of a plurality of inclinations, raft shelves and panel be connected, before processing, sheet material has passed through the processing of minimum aridity, environment during use is conventionally more moist, and timber is in swelling state, and the oat tail groove structure of inclination can be by this expansion to whole panel.And owing to being same material processing, the coefficient of expansion is identical, panel, raft shelves, reperuse and frame visual as a whole, pressure is dispersed on whole dovetail groove and is not limited to the fixing point of minority.Therefore, can effectively control when solid desktop expands and crack.

Through making repeated attempts and reaching experimental verification more than a year, adopt the solid desktop of this structure exempting under paint condition, through spring, summer, autumn and winter, the test of moist and dry environment, the cooperation on desktop between solid wood board is still very tight, and table body structure is very solid.This structure applications is on the high-grade family properties such as redwood, narra, and effect is very good.

Although above, for specific embodiment, the present invention is had been described in detail; but those skilled in the art is to be understood that; the invention is not restricted to above disclosed specific embodiment; in the situation that not departing from essence of the present invention and scope; the present invention is modified and replaced; such as being applied on the solid wood furnitures such as stool, cupboard, still belong to the scope that the claims in the present invention are protected.
