Description

[Detailed Description of the Invention] The present invention relates to an assembly type support frame for a white board, which is used as a teaching material or office supplies, and is designed to fit and support a so-called white board.

In recent years, the development of writing instruments has been remarkable, and various types of whiteboards for writing using writing instruments impregnated with water-soluble ink have come into circulation, replacing blackboards with chalk, which had been widely used in the past. In this case, the mainstream construction of small whiteboards for stationery is an assembly system in which the whiteboard main body and a frame-like support frame arranged around the main body are assembled. However, the structure of the currently used prefabricated support frame is complex, making it difficult to assemble easily as a teaching material for students' vocational home economics, and the packaging after assembly is unsightly. It has become something that does not exist.

This invention was created in view of the above circumstances, and is mainly used as a practical teaching material for students' vocational home economics.
The support frame and connection jointer are simplified, allowing for easy assembly.

Hereinafter, the present invention will be described with reference to drawings of embodiments.

Reference numeral 1 denotes an aluminum frame having an equilateral mountain shape of a thin plate having both ends cut orthogonally a to have an appropriate length, and four aluminum frames 1 are formed. In this case, if all four are of the same length, it will be a square frame, and two of them will be longer than 2.
Of course, if you shorten the book, it will have a rectangular framework. 2 is a right-angled metal joiner body 2' having a lipped shape in cross-section, with the inner width l of one side being approximately equal to the width l' of one side of the aluminum frame 1, and the front side of the joiner body 2'. This is a metal corner jointer formed by arranging a 45 cut line 3 in the center of the right angle fold of 2a and slightly convexly curving the front side 2a outward, and four corner jointers 2 are formed. be.

When constructing the support frame 4 using the corner jointer 2 and the aluminum frame 1, first insert one end of the aluminum frame 1 into the insertion opening 5 of one of the corner jointers 2, and insert the hooked edges 1a, 1a is inserted between the lip portions 2b and 2c of the corner jointer 2, and inserted until the cut surface a, which is the tip of the aluminum frame 1, comes into contact with the right-angled side wall surface 2d of the corner jointer 2. It is something that

Next, one end of the aluminum frame 1 is similarly inserted into the other insertion port 5 of the corner jointer 2, but in this case, the tip 1b of the aluminum frame 1 is inserted into the orthogonally adjacent aluminum Tip part 1 of frame body 1
If the aluminum frame 1 is positioned so that it overlaps the aluminum frame 1, one side edge 1a of the aluminum frame 1 just inserted will be pushed up by the thickness of the aluminum frame 1, so it will fit firmly into the lip 2b. Become something. Of course, in conjunction with this, the aluminum frame 1 which is inserted in advance
One side of the corner joiner 2 is strongly pressed against the front side 2a side of the corner joiner 2. Since this front side portion 2a has a convex curve b and has some elasticity, the next aluminum frame 1 can be inserted even if it is a little strong.

After that, fit the corner jointer 2 to be connected in the next stage to the other end of the inserted aluminum frame 1, insert another aluminum frame 1 into the other insertion port 5 of the corner jointer 2, and then sequentially insert the corner jointer 2. and aluminum frame 1,
As a whole, the support frame 4 is made up of squares.

In this case, when fitting the corner jointer 2 for final closing, since the corner jointer 2 is divided into two parts at the cut line 3 with a 45° cut in the center, the cut line 3 is Kai as corner jiyoiner 2
Since it can be expanded slightly to the left and right, it can be inserted easily.

Inner frame surface 4a of support frame 4 assembled in a square manner in this way
A white plate 6 is fitted into the section.

As mentioned above, the prefabricated support frame of the present invention has corner jointers arranged on all sides with a lip-shaped cross section, and the front side is convexly curved, making it possible to create an aluminum frame with an equilateral ridge-shaped (L-shape) shape. Overlapping fitting is easy and a strong corner connection is possible, and since the corner jointer is provided with a cut line in the center that can be opened slightly to the left and right, the frame as a whole can be assembled without difficulty.
Furthermore, since the cut end faces of the aluminum frame are perpendicular, it is possible to assemble at right angles. Moreover, since the structure of the present invention is simplified, it is easy to manufacture, lightweight, and inexpensive, and can be used as a learning teaching material for students in schools. Of course, this has practical effects such as ease of disassembly after assembly.

Claims (1)

[Scope of utility model registration request] In an assembly type support frame in which four frame members are assembled into a rectangular shape and a white plate is fitted, four thin plate equilateral mountain-shaped aluminum frames with both ends cut at right angles and the inner width of one side are pieces of the aluminum frame. A right-angled metal joiner body with a cross-sectional lip shape that is approximately the same as the width is formed by placing a 45° cut line in the center of the front side of the joiner body and slightly convexly curving the front side. An assembly type support frame for a white board, which comprises four corner joiners arranged on four sides, and in which ends of an aluminum frame body are inserted and fitted into openings at both ends of the corner joiners arranged on four sides.
