Description

The utility model relates to products consisting of several parts, for example, to apparatuses and devices for physical exercises and training devices, in particular to structural elements of gymnastic ladders.

There are many designs of sports complexes, including at least one gymnastic ladder with height-adjustable supports, installed in the thrust between horizontal surfaces, for example, [Patent of Russia No. 74568, publ. 07/10/2008], and also, preferably, a metal power bracket with a horizontal bar, mounted on the vertical support elements of the gymnastic ladder [Patent of Russia No. 53134, publ. May 10, 2006, Russian Patent No. 2611943, publ. 03/01/2017].

To ensure the convenience of transportation of sports complexes, their compactness during packaging is necessary, which is achieved, in particular, by making the racks of the gymnastic ladder collapsible.

None of the identified sports complexes is transformable; there are no connecting nodes in the elongated elements of these structures.

The technical solution of the connecting node is disclosed in the sports complex closest to the claimed device [Patent of Russia No. 153138, publ. 07/10/2015], containing a gymnastic ladder, each of the side vertical racks of which is made of at least two parts and is equipped with brackets for attaching the gymnastic ladder to a vertical plane. The connecting node at the junction of the parts of each side rack is a bracket with the possibility of their attachment to each other, while the bracket is made in the form of a rack, at one end of which there is a plate for fastening to the wall, and at the other end a plate for connecting the parts of the side rack.

The connecting assembly for two parts of the side racks of the gymnastic ladder of the well-known sports complex is complex and does not allow changing the configuration of the ladder.

The task is to expand the range of connecting nodes by creating a connecting node with a changeable configuration, for example, for a transformable sports complex.

The technical result is the solution of the problem by creating a connecting node with a variable configuration, which allows parts of the elongated product to occupy various variable mutual positions, for example, a gymnastic ladder to take the form of both a vertical projectile and a "Pickler triangle" [5] (hereinafter "triangle" ) with the ability to change the angle at the top.

The task in the connecting node for an elongated product with a generally rectangular cross-section, which consists of two parts, is solved by the fact that each of the specified parts of the elongated product is made with the first hole for accommodating the axis connecting the specified parts of each elongated product with each other with the possibility of rotation relative to each other, as well as each of the said parts of the elongated product is made with a set of second holes for installing an element for fixing the relative position of the parts of the elongated product, and the said second holes are placed along an arc of a circle with a center in the center of the first hole.

The claimed connecting unit can be completely or partially made of wood, or plywood, or plastic, or metal.

The elongated product is preferably a side post of a gymnastic ladder, and said first hole in that part of the elongated product that is external to the gymnastic ladder can be made blind, or it can be made through.

The drawings show non-limiting examples of the implementation of the claimed connector.

In FIG. 1. shows an image of one of the implementations of the connecting node.

In FIG. 2 shows a section along A-A of the connecting node of FIG. 1.

In FIG. 3 is an image of another implementation of the connector node.

In FIG. 4 shows a section along A-A of the connecting node of FIG. 7 with the fixed element installed.

In FIG. 5 shows an image of one of the implementations of the gymnastic ladder with the claimed connecting nodes in the form of a vertical structure.

In FIG. 6 shows a section along A-A of the gymnastic ladder according to FIG. 5.

In FIG. 7 shows an image of a gymnastic ladder with the claimed connecting nodes according to FIG. 5, 6, transformed into a triangle.

Each connection node 1 shown in FIG. 1-4 is formed by the connected parts 2 and 3 of the corresponding elongate product. Each of said parts 2 and 3 is made with a first hole 4 for accommodating an axis connecting said parts of each elongated product with each other with the possibility of rotation relative to each other.

In the example implementation of the connector node 1 shown in FIG. 1-2, the specified first hole 4 in that part of the elongated product, which is internal when used as a side rack of a gymnastic ladder, in this example, in the lower part 3, is made through, and in that part of the elongated product, which is external when used as a side rack of a gymnastic ladder, in this example - in the upper part 2, it is made deaf. One of the crossbars 5 performs the function of an axis connecting said parts 2 and 3 of each side post with each other with the possibility of rotation relative to each other, and connects both side posts.

In addition, each of the specified parts 2 and 3 of the side post is made with a set of second holes 6 for installing an element for fixing the relative position of the parts of the elongated product, and the said second holes 6 are located along an arc of a circle with a center in the center of the first hole 4. In Fig. 2 shows an example of the implementation of the fixing element in the form of the first nut 7 installed in the lower part 3 with internal and external threads and the first bolt 8 screwed into the specified nut 7 with a safe (for example, wooden) pad 9.

The fixation element can be made of any known design, corresponding to the material of the elongated product.

In the example implementation of the connector node 1 shown in FIG. 3, 4, said first opening 4 is made through both parts 2 and 3 of the elongate product. Then the function of the axis connecting these parts 2 and 3 of each elongated product with each other with the possibility of rotation relative to each other can be performed by one of the crossbars 5 protruding beyond the outer surface of the elongated product (not shown in the drawings) and connecting both elongated products , or an additional element 10, for example, a bolt or dowel, which can be installed in the gap between the crossbars 5 separately for each elongated product.

In addition, each of the specified parts 2, 3 of the elongated product in this implementation example is also made with a set of second holes 6 for installing an element for fixing the relative position of the parts of the elongated product, and the said second holes 6 are located along an arc of a circle with a center in the center of the first hole 4. In FIG. 4 shows another example of the implementation of the locking element in the form of a second bolt 11 with a safe (for example, wooden) pad 9, threaded through and screwed into the second nut 12, also equipped with a safe pad 9.

An example of the use of the claimed connecting node 1 is shown for a vertical gymnastic ladder (Fig. 5-6), which contains a set of crossbars 5, two side racks, each of which consists of two - top 2 and bottom 3 - parts. Each side post is made with a connecting node 1 for connection and mutual rotation of the parts of the side post.

The triangular gymnastic ladder shown in Fig. 7 also contains a set of crossbars 5, two side racks, each of which consists of two - top 2 and bottom 3 - parts. Each side post is made with a connecting node 1 for connection and mutual rotation of the parts of the side post.

The manufacture of the claimed connecting node on the example of a gymnastic ladder is as follows.

The gymnastic ladder, for which the claimed connecting unit is used, can be made of wood, or plywood, or plastic, or metal, in whole or in part. The most technologically advanced and economical is its implementation from plywood.

The manufacture of a gymnastic ladder begins with the selection of plywood for the absence of chips, defects in the upper veneer.

Next, the structural elements are laid out (parts 2 and 3 of the side racks of the gymnastic ladder) on plywood sheets, bypassing defects.

After that, the indicated elements are cut out with a margin of 3-5 mm from the contour of each element. Then each element is framed according to the template and all the holes prescribed by the design are drilled (first holes 4 and a set of second holes 6, as well as holes for installing crossbars 5 in parts 2 and 3 of each side rack,).

All ends and planes of structural elements are ground. The crossbars are also ground and cut to size.

Next, chamfers of 45 degrees are removed (not shown in the drawings) on all plywood elements and the chamfers are ground.

Then the final general grinding is performed for painting and painting of all elements with varnish, as a rule - in 3 layers.

Next, the gymnastic ladder is assembled.

In the implementation example, when one of the crossbars 5 is the axis of the connecting node 1, parts 3 of the side elements of the gymnastic ladder with through first holes 4 are put on this crossbar 5. All the crossbars 5 are inserted into the corresponding holes on the indicated parts 3 of the side elements, glued with glue and tightened confirmations or other screw fasteners.

Next, on the crossbar 5, which is the axis, put on parts 2 of the side elements of the gymnastic ladder and also wind the crossbars 5 between them, glue and fix with confirmations or other screw fasteners.

In the implementation example, when none of the rungs 5 is the axis of the connecting node 1, both parts 2 and 3 of the side elements of the gymnastic ladder are assembled separately. Each crossbar 5 is fixed in the corresponding hole with glue and then fixed with a confirmation or other screw fasteners. Further, parts 2 and 3 of the side elements of the gymnastic ladder are connected in the first hole 4 to a bolt with a nut or other hinged fasteners, forming a connecting node 1 on each side element.

In each of the examples of implementation of parts 2 and 3 of the side elements of the gymnastic ladder 1, by rotating around the crossbar 5, which acts as an axis, they are installed in one line, the fixing elements are inserted into the second holes 6, for example, in the form of the first nut 7 with internal and external threads and screwed into the specified nut 7 of the first bolt 8 with a safe wooden plate 9 (see Fig. 1-2), or, in another implementation example, the second bolt 11 with a safe wooden plate 9, threaded through and screwed into the second nut 12, also equipped with a safe overlay 9 (Fig. 4).

Next, the gymnastic ladder is transformed into a triangle shape.

In each of the examples of implementation of parts 2 and 3 of the side elements of the gymnastic ladder, rotating around the crossbar 5, which acts as an axis, is set at a prescribed angle, the fixing elements are inserted into the second holes 6, for example, in the form of the first nut 7 with internal and external threads and screwed into the specified nut 7 of the first bolt 8 with a safe wooden plate 9 (see Fig. 1-2), or, in another implementation example, the second bolt 11 with a safe wooden plate 9, threaded through and screwed into the second nut 12, also equipped with a safe plate 9 (FIG. 4).

Thus, the technical result of creating a connecting unit with a variable configuration has been achieved, which allows parts of an elongated product to occupy various variable mutual positions, for example, a gymnastic ladder to take the form of both a vertical projectile and a "Pickler triangle" with the possibility of changing the angle at the top.
