HOLLOW ELEMENT JOINT ASSEMBLY

The docking unit for hollow elements belongs to the field of frame tent structures and can be used as a quick detachable connection of hollow elements of frame tent structures, for example, umbrellas, tents, tents, pavilions, awnings, trade equipment, furniture.

A known knot for joining hollow elements (see UKRAINE patent for utility model No. 1095 or RUSSIAN certificate for utility model No. 20818), containing an external hollow element, an internal hollow element that can be inserted one into another.

The docking unit of the hollow elements is implemented in the design of the umbrella, where one hollow element is the umbrella stand, and the other hollow element is the umbrella socket, which form a detachable connection.

The known design is designed for small power loads on docked hollow elements.

The utility model is based on the task, the hollow element docking unit, which is subject to improvement WITHOUT the hollow element docking unit containing the external hollow element, the internal hollow element, which can be inserted into each other, according to the useful model, which differs in that both are hollow the elements contain at least one hole that can be located opposite each other when joining the hollow elements, with a button spring-loaded from the inside of the inner element in the hole inside a hollow element, the end of which protrudes from the hole of the internal hollow element and has the ability to recess when the button is pressed into the internal hollow element, and also enter the hole of the external hollow element when the holes of the hollow elements are located against each other when the hollow elements are joined and exit the hole of the external hollow element

when a button is pressed outside the external hollow element when undocking the hollow elements.

EFFECT: fast and reliable fixation of docked hollow elements is achieved and, if necessary, their quick undocking, is suitable for significant power loads on docked hollow elements.

The spring-loaded button in the openings of the hollow elements with power baffles works on a cut like a pin or key connection. A steel button with appropriate cross-sectional dimensions is able to securely fix docked hollow elements. The spring allows the button to automatically enter the specified operating position in the hollow elements to be connected or disconnected and does not allow the button to spontaneously exit the working position in the joined hollow elements. To disconnect the hollow elements, only directed force is required on the end of the button protruding from the outside of the internal hollow element.

The first additional difference is that the button is spring-loaded with a single bar spring.

The technical result of the first additional differences: simplicity and reliability of the design, the ability to withstand large power loads.

The second additional difference is that the button is spring-loaded with a leaf spring.

The technical result of the second additional difference: the design is more compact, takes up less space inside the internal hollow element. It can be used in hollow elements with a small cross-sectional diameter and significant force punches on the joined hollow elements.

The docking station of the hollow elements is shown in the drawings (see figures 112).

The docking assembly of the hollow elements comprises an external hollow element 1, an internal hollow element 2, which can be freely inserted into the external hollow element 1.

Both hollow elements 1, 2 are made in the form of pipes of a closed cross section, for example, steel pipes of a goblet or rectangular cross section. Both elements 1, 2 have a galvanic and / or polymer antifriction coating.

Both hollow elements 1, 2 contain one or two through holes 3 opposite each other in each hollow element 1, 2.

The longitudinal axis 4 of the holes 3 of the external hollow element 1 when joining the hollow elements 1, 2 coincide with the axes 4 of the holes 3 of the internal hollow element 2.

The hole 3 of the inner hollow element 2 contains one spring-loaded inside the hollow element 2 with a whole bar spring 5 to the inner hollow element 2 button 6.

The end 7 of each button 6 protrudes from the hole 3 of the inner hollow element 2 and has the ability to recess into the hole 3 of the inner hollow element 2 by pressing the button 6.

The button 6 is made in the form of a cylinder 8 with a stop 9 at one end of the cylinder 8, for example, in the form of an annular protrusion with a diameter larger than the diameter of the hole 3 in the hollow inner element 2.

The end 7 of each button 6 of the streamlined shape protruding from the inner hollow element 2, for example, as a part of a sphere.

At the end of the button 6 from the stop 9 there is an opening 10 for inserting the end 11 of the spring 5 into it.

The spring 5 is made of a whole steel bar having at least a portion of the coil 12 of the spring 5, turning into straight sections 13c with bent ends 11 for inserting them into the holes 10 of the buttons 6.

The spring 5 can also be made of two leaf springs 14, one end 15 of which is fastened with a riveted connection to a fastener 16, and the free ends 17 of the leaf springs 14 are bent from each other. At the ends 17, the protrusions 18 are fastened for insertion into the holes 10 of the ends of the buttons 6.

The docking unit of the hollow elements 1, 2 can be implemented when docking the hollow elements in the form of couplings, adapters, connecting tees, angles or used in other nodes of frame tent structures for joining their hollow elements.

The device operates as follows.

When assembling the docking unit of the hollow elements 1, 2, the end of the inner hollow element 2 is inserted inside the external hollow element 1. When one of the hollow elements 1, 2 is inserted into the other, one or both spring-loaded buttons 6 are automatically recessed in one hole 3 or two holes 3 of the internal hollow element 2. Next, rotate the hollow elements 1, 2 relative to each other in the radial plane until the recessed one or two buttons 6 automatically enter one or two holes 3 of the outer hollow element 1. After that, both hollow elements 1, 2 do not have the ability to spontaneously disconnect. One or two buttons 6 hold the hollow elements 1, 2 from moving them relative to each other.

When disassembling the docking unit of the hollow elements 1, 2, outside the external hollow element 1, press one button 6 (in the case of one button 6) and recess it into the hole 3 of the internal hollow element 2 with the simultaneous displacement of the hollow elements 1,2 relative to each other holes 3. In this case, the button 6 does not prevent the removal of the external hollow element 1 from the internal hollow element 2 or vice versa.

In the two-button execution, both buttons 6 are pressed simultaneously from the outside of the external hollow element 1 and both buttons 6 are inserted into the holes 3 of the internal hollow element 2, the hollow elements 1, 2 are simultaneously displaced from each other, and then they are disconnected.

The spring-loaded button 6 in the holes 3 of the hollow elements 1, 2 at power loads works on a cut like a pin or key connection. In the steel version, button 6 with appropriate cross-sectional dimensions is able to securely fix docked hollow elements 1, 2. A spring 5 or 14 allows button 6 to automatically enter a predetermined working position in connected or disconnected hollow elements 1, 2 and does not allow the button spontaneously exit the working position in the docked hollow elements 1, 2.

To disconnect the hollow elements, only directed force is necessary on the end 7 of the button 6 protruding from the outside of the internal hollow element.
