Description

[Detailed Description of the Invention] This invention relates to an assembly structure for wagons and other vehicles used for gardening, kitchen use, etc.

In the past, for example, such wagons were mainly made of screws or were framed using predetermined pieces. In the latter case,
In order to leave the base body 20 at the corner of each aggregate, it was necessary to form it into, for example, a rectangular cube along the cross-sectional shape of the aggregate, which made piece processing troublesome and where problems existed. Atsuta (Figure 4). Moreover, the piece 21 is completely inserted into the aggregate. However, this requires forming the end face of each aggregate into a 45 degree slope, and moreover, the purpose is to assemble only two aggregates 22 and 23, and the purpose is to assemble three aggregates together. This was not the case (Figure 5).

Therefore, the present invention was made in view of the drawbacks of the conventional example, and consists of an aggregate with a hollow cross section mainly consisting of the main pillar 1, the side beams 2, and the horizontal beams 3, and the base 4 and the base 4. It is an integrated jointer A in which both sides 5 and 6 are protruded in an L-shape in the right angle direction, and the base 4 is installed in the main column 1.
Fit the side bodies 5 and 6 into the side beam 2 and the horizontal beam 3, respectively, and use the jointer A to frame the main column 1 and the side beams 2 and the horizontal beam 3 at right angles on both sides of the main column 1. There are cut grooves 7 on both sides of the main pillar 1.
is hung from its open end, and the bases of both side bodies 5 and 6 are inserted into this to bury the base body 4 in the main column 1, and both sides of the main column 1 are inserted through the cut groove 7 of the main column 1. The invention consists in an assembly structure for a wagon or the like in which a side beam 2 is sequentially fitted to one side body 5 protruding from the side body 5, and a horizontal beam 3 is fitted to the other side body 6 in sequence, and the manufacturing of the jointer A is simplified. In addition, it is possible to house the jointer A in the aggregate, to make it possible to assemble the three aggregates together, and furthermore, to make it possible to attach the casters of the trolley to a wagon car using the jointer A. be.

In the following, one embodiment of the present invention will be described in detail based on the wagon shown in FIGS. 1 to 3 of the drawings. has a fan-shaped cross section, and is arranged so that the side beams 2 and the horizontal beams 3 can easily face each other at right angles on both sides thereof. Jyointer A is a metal and other shaped material product, with convenient manufacturing and each aggregate 1, 2 and 3.
This is integrally formed for convenience of insertion into the interior, and is manufactured using extruded or molded material. base body 4 and amphilateral body 5 of jointer A,
6 is provided with predetermined fins 8 and enlarged portions 9 in order to fit and fit into each hollow end of the main column 1, side beams 2, and horizontal beams 3, and the base body 4 is Blind rivets 10, 12 and screws 11 are inserted into the inner wall of the main pillar 1, one side body 5 is inserted into the inner wall of the side beam 2, and the other side body 6 is inserted into the bottom wall of the horizontal beam 3, respectively. After fitting materials 1, 2, and 3,
This is to make it more firmly fixed.

Both side walls of the main pillar 1 are slightly recessed, and the side beams 2
And when butting the end face of the horizontal bar 3 against this,
It is designed to be easy to match. The cut grooves 7 formed on both side walls of the main column 1 have a depth necessary for embedding the base body 4 in the main column 1, and ensure the retention of the jointer A in the main column 1. The work of inserting the side beams 2 and the horizontal beams 3 into the both side bodies 5 and 6 protruding from the cut groove 7 can be made convenient. Fitting grooves 13 are provided in the longitudinal direction of the inner walls of the side beams 2 and the horizontal beams 3, and a crest-shaped roof 14 is formed in the upper part of the wagon.
This is for fitting the edge of the roof 14 onto the roof 14 when the roof 14 is covered with the roof 14, and the bottom wall of the horizontal beam 3 is recessed so that it can be used when fixing the other side body 6 to the horizontal beam 3. , which hides the head of the screw 11 that is screwed into the enlarged portion 9. A screw hole 15 is provided in the enlarged portion 9 of the base body 4, and a screw hole 15 is provided in the enlarged portion 9 of the base body 4.
can be screwed onto this.

Now, in the present invention, the base body 4 of the jointer A is first fitted onto the main column 1, then the side beam 2 is attached to one side body 5 of the jointer A, and finally the base body 4 is attached to the other side body 6 of the jointer A. This is for fitting the horizontal beam 3, and the assembly of the main column 1 and the side beam 2 via the jointer A, that is, the two left and right main columns 1, 1.
A rectangular side unit B consisting of two upper and lower side beams 2, 2 is installed at the factory, and a 4
The book crossbar 3 can also be framed separately on the user side, simplifying assembly and making storage and transportation convenient. Note that a cap 17 covers the open end of the main pillar 1 after the framework is assembled.

As detailed above, the present invention consists of an aggregate with a hollow cross section, the main frame of which is a main column, side beams, and horizontal beams;
It is an integrated jointer having a base body and both sides protruding from the base body in an L-shape in a direction perpendicular to the base body, and the base body is fitted into a hollow main pillar, and both sides bodies are fitted into the side beams and the side bodies inside the horizontal beam, respectively, and the jointer is fitted. The main pillar and the side beams and horizontal beams are arranged to face each other at right angles on both sides of the main pillar. Insert the base of the both sides into the main column and embed the base body in the main column,
The present invention is also an assembly structure for a wagon or the like, in which the hollow ends of the side beams and the horizontal beams are sequentially inserted and fitted into both side bodies protruding on both sides of the main column in the cut groove of the main column. Therefore, it is possible to use a single jointer to connect the three aggregates to each other (although the number of side bodies on the base 4 is not limited to two, but one or more sides (the angles between the side bodies do not have to be right angles). ) When protruding,
It is possible to assemble one side beam or horizontal beam to the main column, or several side beams or horizontal beams to the main column, for example in a radial manner.Moreover, the jointer is built-in with the base, and its manufacture is particularly conventional. Compared to the remaining pieces, it is easier to manufacture the base, and
When the jointer A is integrally formed, the fitting operation can be performed more smoothly and quickly, and the manufacturing cost can be further reduced. Further, when a screw hole is bored in the base body, it is possible to use such a jointer to attach a trolley caster of a wagon.
