Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fitting for joining a vertically grooved prismatic member and a horizontally grooved horizontal frame member, which have been widely used in product shelves and the like in recent years.

As shown in Utility Model Publication No. 55-6981, the present inventor has
We proposed a joining fitting suitable for joining a horizontal frame member to a cylindrical member having a number of beautiful ridges radially formed on its outer periphery.

However, the coupling fitting has a top and bottom triangular wall formed on the outside of the tip through a horizontal groove in the middle part, and a bridge part formed in the top and bottom at the rear end via a horizontal groove in the middle part, and the upper and lower bridges. An integral guide frame is provided with a wire hole vertically arranged in the part thereof, and within the guide frame, outward hook parts facing in opposite directions are formed at each tip of each bifurcated leg, and the above-mentioned guide is formed on the substrate surface of the rear end. An integral sliding plate is provided with a play hole having approximately the same diameter as the wire hole at the rear end of the frame, and each hook portion at the tip thereof is made to protrude to the outside of the triangular wall at the tip of the guide frame, and the play hole at the rear end is inserted into the rear end of the guide frame. Move it forward to a slightly forward position than the wire hole at the end and insert it, then screw the screw through the upper wire hole at the rear end of the guide frame and insert the conical tip at the lower end through the free hole at the rear end of the sliding plate. By intervening in the wire hole at the bottom, the sliding plate is moved back in the process where the free hole matches the wire hole, and at this time, each outward hook at the tip slides and expands the outer surface of the triangular wall at the tip of the guide frame. The horizontal frame member is horizontally connected by adhering to the beautiful ridge of the cylindrical member.

However, the structure of this mechanism not only requires materials and labor to manufacture due to the structure of the guide frame, but also requires that the wire be inserted in the appropriate position between the wire hole and the free hole of the slide plate when assembling the guide frame and the sliding plate. In addition, when a horizontal frame member is connected to a column member, the horizontal frame member is supported at the tip of the sliding plate at the base of the outward hook, so it has poor load bearing capacity when heavy objects are placed on it. It has been discovered that there are many disadvantages in terms of materials, manufacturing, assembly, and use, such as the possibility that the sliding plate may be distorted or damaged, causing the horizontal frame member to tilt or fall.

The inventor of the present invention has conducted further research in order to eliminate the disadvantages of slanting, and has finally succeeded in obtaining the following excellent coupling fitting.

That is, as shown in the drawings of the embodiment, on the longitudinal central axis of the plate surface of the elongated metal bottom plate 7, outwardly facing hooks F and F'' are formed at the tips in opposite directions in plane, and these outwardly facing The metal elongated cedar plates 3 and 3', which have elongated through-holes H and R formed on the sides that coincide with each other from the slightly deeper part of the hook to the rear end, are stacked vertically, and the rear ends of the overlapped parts are riveted. In the above-mentioned elongated groove of the actuating plate, the tip is formed into a planar arrow shape T, and protrusions 8, 8' are provided on both sides of the base. A protruding wedge 2 is interposed so that the tip of the beautiful T faces the overlapping gap between the elongated cedar boards 3 and 3'. The insertion holes E and E' of each protruding piece 8 and 8' are bored, and the insertion hole E of one side is bored.
Each metal side plate 4 with wire holes R drilled slightly closer to the rear.
, 1 are assembled into a rectangular gutter shape by inserting each of the protrusions into their respective insertion holes, and an elongated metallic cover plate 6 is attached to the upper surface of these both side plates, and the wire holes R of the side plates 4 are assembled. The screw 5 is screwed into the screw 5 so that its conical tip faces the inner edge of the rear end of the through groove H2 in the actuating plate S.
, t' is a protrusion protruding from the upper edge of each side plate 4, 1 to engage with the side edge of the cover plate 6, 9 is a prismatic member, 10 is a horizontal frame member, and 11 is an inner wall of the horizontal groove W of the horizontal frame member. Insertion hole for screw 5 drilled in L
M indicates a hollow portion of the horizontal frame member 10, and M indicates a vertical groove between each of the key-shaped protrusions 7 which are opposed and protruded along the lateral and inner sides of the prismatic member 9, respectively.

Since this metal fitting is constructed as described above, when horizontally connecting the horizontal frame member 10 to the prismatic member 9, the outward hook portion of this metal fitting is inserted from the upper end between the projecting edges Y of the prismatic member using the usual method. F. After inserting the side plates 4.1 and the covering plate 6 portion attached to these, insert them into the hollow part of the horizontal frame member 10, and then insert the screw 5 into the side of the horizontal frame member. When screwed into the wire hole R of one side plate 4 through the hole 11 and the conical tip of the screw gradually intervenes from the inner edge of the rear end of the elongated grooves H and I of the sliding plate S, the sliding plate retreats. The inner surface of the outward hook portions F and F″ is a prismatic member 9.
At the same time, the arrow-shaped T tip of the wedge 2 approaches the key-shaped ridge Y of the wedge and presses it together with the tips of the side plates 4 and 1, and as the sliding plate S retreats, each of the elongated cedar plates forming the sliding plate 3 and 3', the outward hooks at the tips of these long slender cedar plates are expanded, so that the left and right outer ends of these outward hooks meet the surfaces of the respective projecting edges Y of the prismatic member 9. It also comes into pressure contact with the inner wall surface.

As described above, this metal fitting is expanded at the same time as each of the outward hooks at the tip retreats as the sliding plate retreats by screwing in the screw, so that the horizontal frame member can be expanded at the same time as the inner surface of the key-shaped protrusion of the prismatic member. It can be tightly and firmly bonded to both sides of the picture, and when removing the horizontal frame members or changing the vertical height, each outward hook can be loosened or tightened by simply unscrewing or tightening the screws. Therefore, it is of course easy to remove or change the height, but in particular, this metal fitting has a special structure in which, as the sliding plate retreats, the arrow-shaped tip of the wedge fits into the gap between the overlapping slender cedar plates that make up the sliding plate. Because it intervenes in the wedge, it can be expanded reliably with less frictional resistance.The horizontal frame member suspended horizontally on the prismatic member constitutes the wedge and the sliding plate that interposes the wedge. The bottom plate, which is a component of this metal fitting, has a great load-bearing capacity because it is supported by long thin cedar boards in the vertical direction, and therefore has the effect of allowing heavy objects and shoes to be easily placed on it.
The long slender cedar boards, etc. that make up the side panels, the cover plate, and the sliding plate can all be obtained by sheet metal processing, but since they only need to be assembled, materials and costs can be saved, and there are practical benefits that can be obtained at a very low cost. This is an extremely useful invention for this kind of combination in all prefectures.
