Summary of the invention

Task of the present invention provides a kind of frame that is used for an embroidery machine, and this frame is structurally fairly simple significantly, part is less, weight is lighter, and is however still the same with known rack firm, perhaps in addition compare more firm.

According to the present invention, above-mentioned task is solved through following measure: forebay and/or afer bay are to be formed by a shaped piece that extends longitudinally basically, and the height of this shaped piece is corresponding to bracket height.This just obtains the better simply significantly in the past structure of a kind of ratio.Therefore the manufacturing of frame has also just been simplified greatly, but also can reach the purpose that obviously reduces weight.In addition, some face of shaped piece provides such possibility, for example can fixed bobbin support or cone pulley support, and do not need the installing plate of the sort of special use in the past.Other face can be used as installed surface, to be used for assembly or vertical supporting member.

For small-sized embroidery machine, forebay and afer bay can constitute through a shaped piece length.For more large-scale embroidery machine, forebay and/or afer bay preferably are made up of a plurality of profile lengths that are connected with each other or part.Their weight is lighter, so can be installed in the rigging position place of embroidery machine time saving and energy savingly.

Said shaped piece is a rectangular structure of hollow shaped piece of reality basically.It can have an aperture, and is extending on the part of this shaped piece or on its whole length in this aperture, thus the rinforcement bar of the each interval distance of in the inside of this shaped piece, having packed into, and for example can fix through welding.Rinforcement bar can be a plate shape.Be used for also preferably disposing rinforcement bar below the column of bobbin cradle, these rinforcement bars by a kind of hollow body, for example make, so as to bearing the load of column and bobbin cradle by a kind of sheet material of crimping.

Proved that following measure is particularly advantageous: the shaped piece that is used for forebay and afer bay is processed through carrying out crimping for a sheet material.But said shaped piece also can be a kind of shaped piece of extrusion molding.Be used to have the instrument cost of shaped piece of extrusion molding of this size yes quite high.But with regard to corresponding production number of packages, extruding formation method maybe be more worthwhile than curling.Corresponding situation also is applicable to by rolling produces shaped piece.

The invention still further relates to the use of the frame of being furnished with a frame base, its installed surface is disposed generally on half of distance between the upper wall of floor and afer bay or forebay and highly locates.

The specific embodiment

Frame according to background technology shown in Fig. 1 to 5 has been done preliminary assessment.

Also have three rack sections in the frame according to an embodiment of the invention shown in Fig. 6 to 12, they are called A, B and C respectively.This frame but also can prolong through other part according to the version of part B is so that be assembled into a bigger embroidery machine.But also can part A and B be designed to single part.In Fig. 6 and 12, also show the column 15 that is used for bobbin cradle.Guide rail shown in Fig. 1 16 illustrates.Column 15 still be guide rail 16 be not theme of the present invention.Or rather, emphasis of the present invention is the scheme of afer bay 11 and forebay 13.Can find out this scheme from Fig. 7 a to 10a especially, wherein comparison diagram 2 to 5 just can clearly illustrate that the difference of comparing with background technology especially.

As shown in Figure 6, afer bay 11 for example is made up of three part A, B, C, and this three part for example adopts screw connecting mode and is connected with each other.In order to understand fully the structure of afer bay 11, for example only need to observe the rearview of part A shown in Fig. 7 b and combine just much of that according to the front view of Fig. 7 a.This part is made up of a shaped piece that extends longitudinally 51 basically, and its height is corresponding with desirable bracket height.Internal interval at shaped piece 51 has been arranged rinforcement bar 53,55 (Fig. 7 b) apart from ground.Rinforcement bar 53 is tabular.Rinforcement bar 55 designs more intensely, so as to bearing the load of column 15 (Fig. 6) and bobbin cradle.Rinforcement bar 55 for example can be made through carrying out crimping for a sheet material.

Shaped piece 51 can be referred to as hollow shaped piece, and it is actually rectangular.It the sheet material of handy crimping make.It has an in fact vertical wall 57.Flatly extend a lower wall 61 and a upper wall 63 from wall 57.Extend a wall 65 downwards from upper wall 63 a bit ofly; Make progress from lower wall 61 and to extend a wall 67 a bit ofly.Thereby aperture 68 is restricted, and this aperture provides and gets into the inner passage of shaped piece, and allows

rinforcement bar

53,55 to realize the fixing of welding or other form with shaped piece 51.Aperture 68 shown in version in the whole length of extend past shaped piece 51.Below shaped piece 51, welded mounting flange 69.

Can find out that especially wall 57 makes to form a passage 59 therein that this passage is along the longitudinal extension of shaped piece 51 like crimping from Fig. 7 a and 8a.By this way, three different installed surfaces 58,60,62 on wall 57, have just been formed.

The sheet material that is used to make shaped piece 51 is metallic plate preferably.In this case, the thickness that proves sheet material is advisable with 6mm.

Shown in Fig. 8 a and 8b, B, two parts of C design with part A in principle identically, only are a bit long.Therefore can be with reference to the explanation of front.

As shown in Figure 6, forebay 13 for example is made up of three part A, B, C, and these three parts for example are joined to one another through screw connecting mode.In order to understand the structure of forebay 13, for example only need to observe the front view of the part A shown in Fig. 9 a and combine the rearview shown in the 9b just enough.

Now forebay 13 is compared also and can find out with described afer bay 11: its structure is identical basically, so need not elaborate.The shaped piece 51 ' of forebay has wall 57 ', 61 ', 63 ', 65 ', 67 '.This shaped piece also is along the longitudinal extension of embroidery machine, and has a height, and this height is corresponding with desirable bracket height.Aperture 68 ' then is positioned at the front side, and passage 59 has not had.Cancelled a kind of rinforcement bar of the sort of rinforcement bar 55 shown in Fig. 7 b.This is because forebay 13 must supporting upright post 15, so plate shape rinforcement bar 53 ' is just much of that.

Forebay is as a special advantage along the design of the shaped piece of the longitudinal extension of embroidery machine: can be used as fixed head at the wall 65 ' of shaped piece shown in Figure 10 a and be used for bobbin support (not shown).Can see many fixing holes 71.In addition, the wall 57 ' of shaped piece can be used as fixed head and is used for cone pulley support (not shown).Can see the fixing hole 73 that is used for the cone pulley support.

Shown in Figure 11 according to the situation of frame after it is installed on the pedestal 81 that meets known background technology shown in Figure 1.Can clearly be seen that the gap 14 that is used for the bobbin cradle (not shown), this bobbin cradle also can move down in raceway groove 83.

In Figure 12, represent that with side view the frame at embodiment shown in Fig. 6 according to the present invention is installed in state later on the pedestal 82 at it.In the present embodiment, afer bay 11 and forebay 13 low than according to the embroidery machine of background technology all.The installed surface 85 of pedestal 82 is disposed generally on half highly the locating of upper wall 67, the distance between 67 ' of floor 84 and afer bay 11 or forebay 13.The installed surface 85 of pedestal for example can be on the floor about 50cm more than 84.This is with regard to no doubt cost up of pedestal, but this shortcoming obtains more compensation owing to the transportation of the lower and lighter embroidery machine of the cost of frame.

But advantageously the height of machine has reduced, because so the length of the arm of force has also reduced, the arm of force for example is formed by afer bay and column 15.This situation also allows to adopt lighter structure and the corresponding weight that reduces.

Rack construction can be made many modifications, but can not run counter to design of the present invention.Therefore, for example used shaped piece can be combined by a plurality of part shaped pieces.

Can sum up as follows:

The frame that is used for embroidery machine comprises a forebay 13 and an afer bay 11.Frame is made up of a shaped piece 51,51 ' basically before and after these two, and this shaped piece is along the longitudinal extension of embroidery machine, and its height is corresponding to bracket height.Shaped piece 51,51 ' is to make with the sheet material of a crimping.The frame of being introduced is structurally simpler, and manufacturing cost is lower, and its weight is also much little than known frame.Also can further reduce weight, need only pedestal so be designed and make its installed surface obtain to increase to get final product.
