Definitions

• This invention relates to a method of fastening hollow sections, preferably hollow sections which are to form case ⁇ ments or window or door frames- to one another by means of connection pieces, each such connection piece having two limbs one of which is adapted to"engage one hollow section while the . other limb engages the other hollow section. Moreover, the invention relates to an apparatus for practising the said method.
• connection piece in hollow sections to said hollow sections.
• One problem is that it takes a long time to apply adhesive to the connection piece, especiall if one wants to apply the adhesive over large adhesion surfaces on several of the sides of the connection piece.
• Such an applica tion in fact is so time-consuming that quick-drying or quick- -setting adhesive cannot be utilised because of the risk that the adhesive has dried or set before the connection piece has been brought in position in the hollow sections.
• Another problem is that it is difficult to hold the connection piece during application of the adhesive and that it is difficult to avoid getting oneself and one's work place all soiled with . adhesive.
• a further problem is that it is difficult to avoid exposing one ⁇ self to adhesive fumes, and to place the connection piece in the hollow sections without wiping the adhesive off the connec- tion piece.
• One object of the present invention is to provide a method of eliminating these problems.
• the main characterising features of the method of the invention will appear from appendant claim 1.
• Another object of the invention is to provide a simple apparatus for carrying out the method of the invention.
• the main characterising features of the apparatus will appear from appendant claim 9.
• the method of the invention permits spreading the adhesive very rapidly over large surfaces on several of the connection piece sides simultaneously, while preventing that the operator comes in contact with the adhesive or is exposed to adhesive fumes. As a result, use can be made of quick-drying or quick- -setting adhesives. Besides, it will no more be necessary to introduce into the hollow sections a connection piece to which adhesive has been applied. 5

• the corner piece 5 is held to a plate 6 with the aid of a holding means 7 which is compressed air operated and for this reason is connected to a compressor 1;1 via a conduit 8, a control device 9 and a conduit 10.
• the plate 6 has guiding and clamping means 12 and 5 13 for the hollow sections 3 and 4. Having been placed in the guiding and clamping means 12, 13, the hollow sections are moved by manual or mechanical force towards the corner piece 5 and passed thereonto until their obliquely cut edges 3a, 4a abut.
• the corner piece 5 is then completely enclosed in the hollow sections 3, 4.
• the relative positions of the various parts 3, 4 and 5 will appear from Figure 3.
• the holding means 7 is moved away from the holding assembly 2 on rails 14, 15 provided for that purpose. Instead, a slide 16 also mounted on the rails 14, 15 is moved to a position opposite the holding assembly 2.
• the slide 16 comprises an upsetting assembly 17 having two mandrel holders 18, 19 with compressed air operated mandrels 20, 21. For the operation of the mandrels 20, 21 the mandrel holders
• the slide 16 comprises a hole drillin assembly 24 consisting for example of a compressed air operate drilling machine 25 having a drill 26.
• the drilling machine 25 is connected via a conduit 27 to the control device 9 and via the latter and the conduit 10 to the compressor 11.
• the hole drilling assembly 24 may alter ⁇ natively comprise two drilling machines 28,• 29 set at an angle to each other, if it is desired to drill holes in each hollow section 3, 4 instead of drilling holes with the drilling machine 25 in the corner edge 30 formed by the obliquely cut edges 3a, 4a of the two hollow sections 3, 4 when the hollow sections 3, 3 are assembled.
• the drilling machines 28, 29, their drills 31, 32 and their conduits 33, 34 leading to the control device 9 are shown by dash and dot lines in Figure 1.
• the conduit 40 in its turn comprises a control device 41 for controlling the adhesive pump 39 in suc a way as to dispense adhesive at suitable intervals to the container 36 from an adhesive supply 43 containing an adhesive 42.
• the two hollow sections 3, 4 to be assembled so as to form a corner are made of metallic material and have a cross sectio in the form of a substantially quadrilateral tube 3b, 4b with or without protruding portions (see Figure 2A) .
• the corner piece 5 also is of metallic material and comprises two limbs 5a and 5b whose cross section also is in the form of a quadri- lateral tube.
• the limbs 5a and 5b are so dimensioned as to fit in the tubular parts 3b, 4b of the hollow sections 3, 4.
• the two limbs of the corner piece 5 are formed with a plurality of channels 5f, 5g in their sides 5d, 5e constituting an outer corner edge 5c.
• the said channels are adapted to conduct adhesi 42.
• the hollow sections 3, 4 and the corner piece 5 For the mounting of the hollow sections 3, 4 and the corner piece 5, the hollow sections 3, 4 are placed in their guiding and clamping means 12 and 13, respectively, and the corner piec 5 is brought in position on the plate 6.
• the hollow sections 3, 4 are displaced in the direction of the arrows A and B in Figur 2 until they have been passed onto the corner piece 5 and their obliquely cut edges 3a, 4a abut (see Figure 2) .
• the holding means 7 is moved backwards in the direction of arrow C in Figure 3 and laterally in the direction of arrow D 'in Figure 4. Instead, the slide 16 with the upsetting assembly 17 is moved to its working position which is shown in Figure 4.
• the mandrels 20, 21 are activated so as to urge portions of the outer sides of the hollow sections 3, 4 into recesses of the corner member (for instance depressions inside of raised end portions 5h, 5k of the corner piece 5) or only against the corn piece 5 so that the hollow sections 3, 4 and the corner piece 5 cannot be dislodged in relation to each other.
• the drilling machine 25 is activated so that its drill 26 is caused to drill a hole 44 through the outer corner edge 30 of the hollow sections 3, 4 (see Figures 4A and 5A) such that the hole 44 communicates with both the channels 5f and the channels 5g in the limbs 5a and 5b of- the corner piece 5.
• the slide 1.6 is moved in the direction of arrow E in Figure 5 and the adhesive supplying assembly 35 is moved into working position in the direction of arrow F in Figure 5, whereupon the nozzle 37 is connected to the hollow sections 3, 4 for conducting adhesive 42 into the hole 44 (see Figure 5) .
• the pump 39 is started. It urges adhesive 42 from the adhesive supply 43 into the hole 44 and via said hole into the channels 5f and 5g.
• the adhesive 42 may preferably be supplied at such a pressure that it penetrates into the space between the hollow sections 3, 4 and the sides 5d and 5e of the corner piece 5.
• the adhesive 42 is prevented from penetrating between them.
• the method described does not allow the adhesive to come in contact during its supply with the surroundings int.al. because the space for the corner piece 5 within the hollow sections 3, 4 is closed by the abutting end edges of the hollow sections 3, 4.
• ambiant air canno in any way influence the adhesive and the personnel is not exposed either to adhesive or injurious gases which might arise if the adhesive comes in contact with air.
• Use can be made as adhesive for instance of various types of glue products, depending upon the shape or the material of the hollow sections 3, 4 and the purpose for which they are to be used.
• a quick-dryin glue particularly a quick-setting multicomponent glue.
• the adhesive preferably is of a type such that it retains its volu or expands slightly upon drying or setting to that it fills ou the respective spaces also after drying or setting.
• the apparatus and the method are not either limited to the connec ⁇ tion of hollow sections to provide a corner, but can be used for the connection of hollow sections to form a straight sectio bar. In this instance, the corner piece is replaced by a straight connection piece.
• the holding assembly 2 - as an alter ⁇ native of what is mentioned in the foregoing - may be movable in relation to the other assemblies 17, 24 and 35, or all assemblies 2, 17, 24 and 35 may be movable in relation to each other.
• the apparatus may also be employed only for the fixation of a hollow section 3 or 4 to a corner piece or other connec ⁇ tion piece, whereupon another hollow section can be fixed to the corner piece or the connection piece in another manner.
• the corner piece or the connection piece may be a holder for fixation of the hollow section in a suitable manner.
• each hole 44 in the corner edge 30 there may be arranged several holes in said corner edge 30, in which case each such hole preferably communicates with a channel " or a system of channels in the connection piece 5.
• each hollow section 3, 4 may be provided with one or more holes. The lastmentioned holes are drilled by means of the drilling machines 28, 29 preferably at a distance from the corner edge 30 and preferably at such places where they communicate with inside channels in the connection piece 5
• the adhesive may also be efficiently distrib uted by conducting it into narrow slit-shaped speces between the hollow sections and the connection piece.
• the hollow sections and the connection piece may be of metal, plastics or other suit ⁇ able material.
