Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for connecting a vertical frame and a horizontal frame in a frame assembled in a rectangular shape.

[0002]

2. Description of the Related Art In the case of assembling a rectangular frame with upper and lower vertical frames and left and right horizontal frames, the ends of the vertical and horizontal frames are connected. And conventionally, when connecting the vertical frame and the horizontal frame,
As shown in FIG. 6, the end face of the other frame is abutted against the inner side surface of the one frame, and the screw 31 inserted from the one frame 30 is fixedly connected to the screw hole 33 of the other frame 32.
By the way, in the lattice frame, since the concave grooves 34 for fitting the lattice attachments are formed along the longitudinal direction on the inner side surfaces of the two frames connected to each other, the abutting is performed as shown in FIG. The connection strength is secured by notching the end of the other frame 32 to form a convex portion 35 and fitting the convex portion 35 into the groove 34 of the one frame 30.

However, since the above-mentioned processing requires high precision, attention must be paid to it, which is very troublesome.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide a vertical frame-horizontal frame connecting device in a frame body capable of easily and firmly connecting the vertical frame and the horizontal frame. And

[0005]

In order to achieve the above object, a connecting device for a vertical frame and a horizontal frame in a frame body according to the present invention is assembled in a rectangular shape by upper and lower vertical frames and left and right horizontal frames, And in a frame body in which a concave groove is formed along the longitudinal direction of the inner side surface of one of the vertical frame or horizontal frame, (a) the end surface of the other frame is butted against the inner side surface of the one frame,
(B) The other frame of the vertical frame or the horizontal frame is formed hollow.
Besides, a screw hole is formed inside the hollow part, and a corner block is fitted in this hollow part,
(C) The corner block is formed with a convex portion that fits into the groove of the one frame, and the convex portion is formed with a screw insertion hole facing the opening of the screw hole of the other frame. Characterize.

[0006]

[Operation] When connecting the vertical frame and the horizontal frame, a corner block is fitted into the hollow portion of one frame. In this state, the end surface of one of the frames is brought into contact with the inner side surface of the other frame, and the convex portion of the corner block protruding from the end surface of the one frame is fitted into the groove of the other frame. This prevents one frame from being displaced in the width direction with respect to the other frame. Next, the screw inserted from the other frame penetrates the screw insertion hole of the convex portion of the corner block of the one frame, and is screwed into the screw hole of this frame to be fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The frame shown in FIG. 1 is used for gates and fences. It is assembled in a rectangular shape by upper and lower horizontal frames 1 and 2 and left and right vertical frames 3 and 3, and an attachment 5 is placed inside. A grid 6 is attached. Both ends of a plurality of vertical grids 6a and horizontal grids 6b arranged vertically and horizontally are screwed to a frame-shaped attachment 5, and the attachments 5 are attached to the horizontal frames 1, 2
And a vertical groove 3 is fitted in a groove 7 to be described later formed along each longitudinal direction of the inner surface of the vertical frame 3.

Next, in the above frame, the horizontal frames 1 and 2 and the vertical frame 3 are connected as follows.

A concave groove 7 is formed on the inner surface of the vertical frame 3 as shown in FIGS. A screw hole 8 is formed on the inner wall of the upper and lower parts, and a work hole 9 for allowing a driver or the like to pass through is formed on the outer wall. At the corners of the frame, the end faces of the horizontal frames 1 and 2 are abutted and connected to the inner side surface of the vertical frame 3.

The horizontal frame 1 is formed hollow as shown in FIGS. 3 and 4, and screw holes 11 and 12 are formed in the upper and lower portions inside the hollow portion 10 along the entire length thereof.

A corner block 13 is provided in the hollow portion of the horizontal frame 2.
Are fitted. As shown in FIG. 4, the corner block 13 is composed of a rectangular parallelepiped main body portion 13a and convex portions 13b and 13c protruding from the main body portion 13a. Main body 13a
Is formed in a size that fits into the horizontal frame 1 as a whole, the central portion and the corners are formed hollow, and the wedge-shaped ridges 14 are formed on the outer peripheral surface. Between the hollow portions 15, 15 for receiving the screw holes 11, 12
6 is formed. A pair of upper and lower convex portions 13b and 13c are formed to project from one end of the main body portion 13a. The projections 13b and 13c are formed in a plate shape, and the upper end 17 of the upper projection 13b and the lower end 18 of the lower projection 13c are located above the upper surface 19 and below the lower surface 20 of the main body 13a, respectively. The vertical frame 3 is formed so as to project.
It has a width that fits in the groove 7. Further, a slotted screw insertion hole 21 is formed through both the convex portions 13b and 13c.

In the above structure, when connecting the horizontal frame 1 and the vertical frame 3, the corner block 13 is fitted into the hollow portion 10 of the horizontal frame 1 as shown in FIG. At this time, the main body 13
The ridge 14 of “a” bites into the inner surface of the horizontal frame 1, and the corner block 13 is press-fitted to the horizontal frame 1. Screw hole 1 of horizontal frame 1
1 and 12 are received in the receiving recesses 16 of the corner block 13. Also, the main part 1 of the corner block 13
3a fits into the horizontal frame 1, but the upper and lower end portions 17 and 18 of the convex portions 13b and 13c contact the end faces of the horizontal frames 1 and 2, so that the corner block 13 is recessed into the horizontal frame 1. There is no end.

In this state, the end surface of the horizontal frame 1 is brought into contact with the inner surface of the vertical frame 3. At this time, the convex portions 13 b and 13 c of the corner block 13 protruding from the end surface of the horizontal frame 1 are fitted into the concave grooves 7 of the vertical frame 3. This prevents the horizontal frame 1 from being displaced in the width direction with respect to the vertical frame 3. Next, the screwdriver 23 is inserted from the working hole 9 on the outer wall of the vertical frame 3, and the screw 23 is inserted from the screw hole 8 on the inner wall through the screw receiving plate 24.
To rotate. The screw 23 passes through the inner wall, penetrates the screw insertion holes 21 of the protrusions 13 b and 13 c of the corner block 13, and is further screwed into the screw holes 11 and 12 of the horizontal frame 1.

The same applies to the connection mode of the horizontal frame 2 and the vertical frame 3.

The concave groove 7 of the vertical frame 3 does not have to be for fitting the attachment 5 for attaching the lattice.

The same applies to the case where the end faces of the vertical frames 3 are abutted against the horizontal frames 1 and 2 and connected.

[0017]

[Effects] According to the present invention, the effect of preventing the positional deviation in the width direction can be obtained as in the conventional case by simply fitting the corner block instead of performing the special processing as in the conventional case on the end of the frame on the abutting side. Since it is obtained, the work is very simple and the cost can be reduced.

Further, since the screw from the vertical frame is directly fixed to the screw hole of the horizontal frame regardless of the corner block, the horizontal frame is strongly attracted and fixed to the vertical frame by the screw. Therefore, the horizontal frame and the vertical frame can be firmly connected.
