DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling bracket for connecting a plurality of frame members at a predetermined angle.

[0002]

2. Description of the Related Art Hitherto, a frame material manufactured by extrusion molding to form a frame has been used for a main body of various industrial machines or a cover for covering the main body. As shown in FIG. 9, a fitting groove 31 is formed in the frame member 30 so as to open on each surface extending in the longitudinal direction, and a nut or the like is fitted into the fitting groove 31 to be positioned at a predetermined position. It is configured so that various types of machinery and instruments can be attached. The width of the opening of the fitting groove 31 is made narrower than the depth of the opening by the wall portion, so that when a nut or the like is fitted through the opening, it can be prevented from falling off.

[0003] In using the frame material 30,
It is necessary to connect these at a plurality of predetermined angles. In this case, an assembly fitting 50 is generally used. This mounting bracket 50 is provided with connecting holes 5 at both ends of the L-shaped member.
1, each of the frame members 30 to be connected,
A predetermined number of nuts 52 are respectively passed through the fitting grooves 31 of the frame 30, and the positions of the nuts 52 and the holes 51 are adjusted. Then, the frame members 30 are connected at a predetermined angle by connecting them with screws 53 such as bolts. It is configured to be able to.

[0004]

However, in the above-mentioned bracket for assembling the frame member, a necessary number of nuts must be passed through the fitting grooves in advance, so that one frame member can be connected to another frame member. In the case of assembling a plurality of nuts, problems such as management of the number of nuts and the like become complicated, and it is very difficult to align the mounting bracket with the nuts. Also, for example, in a case where a new frame material is additionally connected between two frame materials connected in parallel to a certain frame material, the nut cannot be passed to the connection position as it is, There are also problems such as the frame material having to be disassembled once.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide a mounting member for a frame material which can be mounted very easily. is there. In order to achieve this object, the present invention relates to a hook member having at least two locking sides arranged at an installation angle of a frame member and capable of engaging with a fitting groove of the frame member, and assembling the frame member. A base member having at least two defined sides arranged at an angle. The hook member and the base member are arranged such that the corresponding locking side and the defined side are always parallel to each other, and the hook member is moved relative to the base member by the driving of the reciprocating driving means disposed on the base member. It is provided movably. Each of the locking side portions is configured to move uniformly in parallel by the movement of the hook member. Preferably, the reciprocating drive means is a screw component rotatably supported by the base member and screwed into the hook member.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 to 8, reference numeral 1 denotes an assembly bracket for a frame material, and two locking sides arranged at an assembly angle of the frame material, which will be described in detail later (in the embodiment of the present invention, 90 °). A hook member 5 having portions 3; and a base member 9 having two defined sides 7, 7 arranged at the same angle as the locking sides 3, 3 of the hook member 5. are doing.

The locking sides 3 of the hook member 5 are formed to have the same length, and are bent so as to be perpendicular to the reference plane 11 of the hook member 5. Also,
In the hook member 5, a screw hole 15 is formed in the bottom surface 13 and a relief hole 17 perpendicular to the reference plane 11 is formed to penetrate the hook member 5, and the screw hole 15 is formed at a diagonal intersection of the bottom surface 13. And a hole perpendicular to the bottom surface 13.

The base member 9 has a reference wall portion 19 which is bent so as to cover the bottom surface 13 of the hook member 5. The reference wall portion 19 corresponds to the screw hole 15 of the hook member 5. Thus, a guide hole 21 is formed. A screw component 23 screwed into the screw hole 15 of the hook member 5 is inserted into the guide hole 21 to constitute a reciprocating drive unit for reciprocating the hook member 5. When the guide hole 21 of the base member 9 and the screw hole 15 of the hook member 5 are viewed from the reference plane 11 side of the hook member 5, the common center line C extends along the extension of the locking side portions 3. Upper intersection P
1 and the specified side portions 7, 7 are formed at positions where they appear to intersect with the intersection P2 in the extension. Therefore, even if the hook member 5 moves due to the tightening or loosening of the screw part 23, the locking sides 3, 3 and the corresponding prescribed sides 7, 7 are always kept parallel. A screw hole 25 is formed in the base member 9 so as to communicate with the relief hole 17 of the hook member 5, and a cover or the like can be attached with a screw after connecting the frame members to form a frame. I have. It is desirable that the thickness m when the base member 9 and the hook member 5 are assembled is set to be slightly smaller than the width of the opening of the fitting groove in the frame member 30 described later.

The frame member 30 connected by the mounting bracket 1 is formed by extruding an aluminum material to form a fitting groove 31 on each surface extending in the longitudinal direction, into which a nut member or the like can be fitted. is there. This frame material 3
0 is an opening 31a that opens to the surface.
And a fitting portion 31b located at the back of the opening portion 31a. The opening portion 31a is formed by the fitting portion 31b by a wall portion 31c.
It is configured to be narrower than the width.

When the two frame members 30 are connected, each of the locking sides 3 and 3 of the hook member 5 of the mounting bracket 1 and each of the prescribed sides 7 and 7 of the base member 9 are connected to each frame member. 30
Then, the screw part 23 is driven to rotate. At this time, since the specified sides 7, 7 are in contact with the inner surface of the fitting groove (the surface facing the opening), the hook member 5 connects the locking sides 3, 3 of the fitting groove 31. It moves so that it may engage with the inside of wall part 31c. In this way, by applying a pulling force from the hook member 5 and the base member 9 to the fitting groove 31, the frame member 30 is connected and held. In addition, due to the connection position of the threaded component 23, by rotating the threaded component 23, the two locking sides 3, 3 are uniformly translated as indicated by the two-dot chain line in FIG. For this reason, force is applied equally to both frame members 30, 30, and the frame members 30 can be stably connected.

Incidentally, the reciprocating means is not limited to the screw part 23 shown in the embodiment of the present invention. For example, when the mounting bracket 1 is enlarged in size, pneumatic or hydraulic pressure is applied. The used cylinder or the like may be used. Also, the angle of each of the locking sides 3 and 3 and the prescribed sides 7 can be arbitrarily selected according to the angle at which the frame member 30 is assembled.

[0012]

As described above, according to the present invention, it is not necessary to insert a nut into the fitting groove of the frame member, and it is possible to control the quantity of the nut, align the nut, and so on. This is advantageous in that the frame members can be connected very easily and a frame member can be newly added without disassembling the once connected frame members. In addition, there is no need to additionally process a screw hole or the like in the frame material at the time of the assembling work, and there is an advantage that the frame material can be quickly assembled.
