Description

DEVICE FOR AN END ATTACHMENT
This invention relates to a device for a profile joint to be used, for example, in building structures that may be disassembled, such as warehouses and scaffolding.
In temporary and removable building structures it is desirable that supporting structures are as flexible as possible. Therefore, the development has been in a direction towards the use of light metals in structures of this kind.
Required time for assembly and disassembly is another aspect of importance in terms of cost, when type of building is to be chosen. Light metals, for example aluminium and its alloys, are very well suited for extrusion into complex profiles. To reduce the consumption of time, many types of quick release couplings have been developed, partly replacing conventional screw connections. Several of the known quick release couplings are clamp-like devices arranged to grip about for example a pipe profile, while simultaneously being clamped against another profile. However, the clamping means itself comprises a screw connection which has to be tightened in the assembling, in order for the quick release coupling to work as intended.
The invention has for its object to remedy the negative aspects of known technique.
The aim is reached according to the invention through the features set out in the following description and in the subsequent Claims.
A building, that can be disassembled, typically comprises supporting profiled columns which are attached to or possibly form, at the transition of the side wall towards the roof, a rafter-like system having the same kind of profile as the columns, or other suitably formed profile(s). Between adjacent columns and rafters, spacer profiles are used as wall beams and ridges. The spacer profiles help to provide necessary rigidity to the structure and to keep the sheathing cloth tight. After the first spacer profiles have been mounted to straighten the structure, the remaining spacer profiles must be positioned and secured to the columns and rafters. Suitable screw-less quick release couplings for attaching such spacer profiles to columns and rafters at random locations along the column/rafter profile are not known.
The device according to the invention comprises a column/ rafter profile provided with one or more longitudinal grooves accessible from the outside. The function of the grooves will be explained below. Two levers are hinged to one another at their respective central portions, forming a tong-like securing element. In at least one of their end portions the levers are provided with a hook-like catch, arranged to be passed, when the levers have been brought together at the end portions in question, through a longitudinal opening in the longitudinal groove of the column/rafter. Possibly the opposite end portion of the levers may also bee passed over another profile. The geometries of the groove and the noses are so formed that when the hook-like end portions of the levers have been passed through the opening of the groove, the levers may be brought apart, whereby the catches engage the groove. Insertion of a locking element into a locking groove between the levers prevent the levers from being brought together and slipping out of the groove. Insertion of the locking element between the levers on the proximate side of the hinge, locks the end portions in a swung-out position, whereas insertion of the locking element between the levers on the opposite side, locks the end portions in a position swung together.
The levers are positioned in a spacer profile and arranged in such a way that in their inactive position they are within the length of the spacer profile. In their projecting active position an opening of the spacer profile corresponds with the locking grooves of the levers. Insertion of the locking element through the opening of the spacer profile and the corresponding locking grooves of the lever arms has the effect that the levers, besides being locked to the groove of the column/rafter profile, also are locked to the end portion of the spacer profile. In a preferred embodiment a spacer profile in the form of a pipe is provided with an end attachment according to the invention at each of its two end portions. At the end portion of the pipe profile, corresponding to the inner end portions of the levers, is arranged an elongated groove extending therethrough. The' inner end portions of the levers are provided with a recess on the side facing the other lever. A punch-like object, possibly the locking body mentioned above, may be inserted through the elongated groove, into the recesses of the levers and further out through the elongated groove on the opposite side of the spacer profile. Because of their hinging connection, the punch brings the projecting end portions of the levers to be swung together. The punch is arranged to be displaced within the elongated groove.
When the spacer profile is being mounted to the column/rafter profile, the punch is placed in the elongated opening and between the grooves of the internal end portions of the levers. When the spacer profile is placed in such a way that the hook-like catches of the levers correspond to the longitudinal groove of the column/rafter profile, the levers are displaced into the longitudinal groove by displacement of the punch in the oval groove of the spacer profile. When the levers are displaced into their projecting positions, the punch is pulled out and then inserted into the locking opening of the spacer profile and in between the two levers which are brought to pivot away from each other as described above, thereby forming a locking connection between the spacer profile and the column/rafter profile. The structure is so formed that it is unnecessary to work the column/rafter profile beyond cutting after extrusion.
In the following will be described a non-limiting example of a preferred embodiment which is visualized in the accompanying drawings, in which:
Fig. 1 shows a section of a wall of a light building; Fig. 2 shows, partly in section, the device in its inactive position;
Fig. 3 shows, partly in section, the device in an intermediate position; and
Fig. 4 shows, partly in section, the device in its active locking position.
In the drawings the reference numeral 1 identifies a section of a wall of a light building comprising a column/rafter profile 2, a spacer profile 3 and a cloth sheathing 4. The cloth sheathing 4 is secured by means of a wedge effect within a cloth groove 17 of the column/rafter profile. The spacer profile 3 is connected to the column/rafter profile 2 by a clamp 5. The column/rafter profile 2 is provided with a longitudinal groove 6, which also forms a longitudinal opening 7. The clamp 5, see Fig. 2, comprises two levers 8, 9 hingingly connected to one another at the hinge 10. Each of the levers 8, 9 is arranged to pivot about the hinge 10, and is provided, besides the hinge 10, also with a hook-like catch 11, 11', a locking groove 12, 12' and a recess 13, 13'. The spacer profile 3 is provided, at its end portion, with a through locking opening 14 and a through elongated groove 15.
The clamp 5 is positioned in the hollow of the spacer profile 3, in which the recesses 13, 13' of the clamp 5 correspond to the through elongated opening 15 of the spacer profile 3. A punch 16 is placed through the elongated opening 15 and the recesses 13, 13'. The clamp.5 is displaceable within the spacer profile 3 restricted by the length of the elongated opening 15. When the projecting end portion of the clamp 5 is to be inserted into the groove 6, see Fig. 3, the clamp 5 is displaced by means of the punch 16 in through the slot 7. With the clamp 5 in this position, the punch 16 is pulled out of the clamp 5 and spacer profile 3, see Fig. 4. The levers
11, 11' are free to rotate restrictedly about the hinge 10. The punch 16 is then inserted through the locking opening 14 of the spacer profile 3 and in between the locking grooves
12, 12' of the levers 8 and 9, respectively. Thereby, the noses 11, 11' are pivoted apart, engaging the walls of the groove 6. In this position the clamp 5 is locking -the spacer profile 3 to the column/rafter profile 2.
By means of the device according to the invention it is possible to assemble/disassemble light buildings fast without any tool other than a hammer, the device providing at the same time a reliable and adjustment-friendly solution of attachment.
