Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a member for connecting profiles used in prefabricated buildings such as sunrooms.

Generally, the above-mentioned connections between the shapes are made using bolts, nuts, rivets, or the like. However, this method not only requires drilling bolt holes and assembling work, which is troublesome, but also exposes the bolt heads at the joints, resulting in a poor surface finish and poor appearance. not good.

The purpose of this invention is to eliminate the need for troublesome work;
Moreover, it is an object of the present invention to provide a connecting member for shapes that can be finished with a beautiful appearance.

The shape connecting member according to the present invention is for connecting at least two extruded shapes in which a fitting groove is formed in the longitudinal direction and a pair of inward engaging protrusions are formed in the opening of the groove. At least two opposing walls for fitting are formed in the longitudinal direction so as to be fitted into the recessed grooves corresponding to the extruded material, and each opposing wall has a pair of outwardly directed engaging protrusions to form the engaging edges. The length from the mating surface to the tip of the opposing wall is formed to be slightly longer than the length from the engaging surface of the inward engaging protrusion to the groove bottom of the groove, and a soft portion is integrally molded at the tip of the opposing wall. It is made of an extruded material made of elastic resin.

The elastic resin may be made of a single synthetic resin such as vinyl chloride, or may be a composite of resins with different properties.

According to the present invention, when connecting at least two extruded members each having a fitting groove formed in the longitudinal direction and a pair of inward engaging protrusions formed at the opening of the groove, the connecting member At least two opposing walls for fitting are formed in the longitudinal direction so as to be fitted into the recessed grooves corresponding to the extruded mold material, and each opposing wall is formed with a pair of outward engaging protrusions. When the facing wall of the connecting member is forcibly pushed into the groove of the extruded member, the outward engaging ridge of the facing wall is engaged with the inward engaging ridge of the groove,
During this engagement, the facing wall flexes in the width direction due to its elasticity, making it easy to engage, and the same elasticity makes it difficult for the two members to disengage. The projecting edge is formed so that the length from the engaging surface to the tip of the opposing wall is slightly longer than the length from the engaging surface of the inward engaging projecting edge to the groove bottom of the groove, and Since a soft portion is formed in the opposite wall, the soft portion of the opposing wall is compressed when both members are engaged as described above, and its restoring force changes the engaged state of both members. The connecting member is firmly held, and since the connecting member is made of an extruded elastic resin material with the above-mentioned soft part integrally molded, it is easy and inexpensive to manufacture, and the opposing wall is easy to bend in response to the above-mentioned engagement. , engagement is extremely easy.

Therefore, the two members are reliably connected by the simple operation as described above, and since bolts and nuts are not used at this time, the appearance of the connected portion can be finished neatly.

Embodiments of the present invention will be described below with reference to the drawings.

A partial horizontal section of the assembled building is shown. The connecting member 1 is
It is used to attach a cover 4 having a substantially V-shaped cross section to a vertical frame 3 that supports a transparent panel 2 made of double glass. In FIG. 1, the upper part of the panel 2 is the interior of the prefabricated building, and the lower part is the exterior thereof.
In this embodiment, front and back and left and right refer to directions from the inside of the building to the outside. Vertical frame 3
is an aluminum extrusion molded material formed almost as a pair on the left and right, and the left and right are integrated by screws 5, and the cross section is U-shaped with the left and right facing each other so as to form a square hollow part. The center wall 6 is formed in a central wall 6 and extends in the front-rear direction, and the front and rear walls 7 and 8 extend in the left-right direction. The front wall 7 is provided with a ridge 1 having a substantially U-shaped cross section for holding down the front surface of the panel 2 via a cushioning material 9 and a caulking material 10.
One end of 1 is latched. The rear wall 8 is formed to have a substantially U-shaped cross section, thereby forming a fitting groove 12 that is open at the rear. A synthetic resin heat insulating material 13 is attached to the tip of the rear wall 8 to press down the panel 2 from the rear. One end of the connecting member 1 is fitted into the fitting groove 12. The cover 4 is attached to the other end of this connecting member 1.
is installed. The cover 4 is made of extruded aluminum and has a groove 14 having substantially the same shape as the fitting groove 12, into which the other end of the connecting member 1 is fitted.

FIG. 2 shows a groove 12 for fitting the front wall 8 of the vertical frame 3,
A connecting member 1 with one end fitted therein is shown in an enlarged view.

The fitting groove 12 is formed in the longitudinal direction of the vertical frame 3, which is an extruded member, and has a pair of inward engaging protrusions 15 formed at its opening. This protruding edge 15 has an inner surface serving as an engaging surface 16, and an opposing surface 17 that is formed in an inclined shape that expands outward. Further, the groove bottom 18 of the groove 12 is flat.

The connecting member 1 is made of an extruded material made of a synthetic resin such as vinyl chloride and has a substantially H-shaped cross section, and includes an opposing wall 19 formed in the longitudinal direction thereof and a connecting wall 20. The width of the opposing wall 19 is slightly smaller than the width of the fitting groove 12 so that it can be fitted into the fitting groove 12. A notch groove 21 having a substantially triangular cross section is formed in the longitudinal direction of the outer surface of the opposing wall 19, so that an outwardly facing engagement member that extends through the notch groove 21 and has one side thereof as an engagement surface 23 is formed. Joint edge 22
is formed. Opposite wall 19 to fitting groove 12
By being fitted, the outward engaging protrusion 22
is engaged inside the inward engaging protrusion 15. In this state, the engaging surfaces 16 and 23 of both projecting edges 15 and 22 are in contact with each other, and the opposing surface 17 of the inward engaging projecting edge 15 is bent against the groove bottom 24 of the notched groove 21. The length of the outward engaging protrusion 22 from the tip of the opposing wall 19 of the engaging surface 23 is the same as the length from the engaging surface 16 of the inward engaging protrusion 15 to the groove bottom 18 of the concave groove 12. An inclined surface 25 is formed so as to be slightly longer and tapered toward the tip of the opposing wall 19 on the outside. Furthermore, a soft portion 25 is provided at the tip of the opposing wall 19. This soft part 2
6 is integrally molded with other soft parts and has appropriate elasticity. Therefore, the soft portion 26 is compressed in a state where both the engaging protrusions 15 and 22 are engaged as described above.

The operation of connecting the vertical frames 3, which are the connected sections, using the connecting member 1 is performed as follows. The tip inclined surface 25 of the opposing wall 19 is located on the surface 17 facing the opening of the fitting groove 12.
When the opposing walls 19 are pressed against each other and the opposing walls 19 are forcibly pushed in from the tips, the opposing walls 19 are bent in the direction of approaching each other, and after the tips reach the groove bottom 18 of the groove 12, the soft portion 26 is pushed in. It is compressed and fitted into the concave groove 12, and both engaging protrusions 15 and 22 are engaged in the above-described state. In this way, engagement can be easily and simply performed by simply pushing the connecting member 1 into the groove 12 of the vertical frame 3. In the engaged state, the opposing wall 19
The elasticity of the engagement prevents the engagement from coming off, and the restoring force of the compressed soft portion 26 is applied to both the engagement protrusions 15 and 22.
Since they act in a direction that presses them against each other, unnecessary gaps are not created in the engaging portions, and the engagement is strong.
