Abstract

The invention relates to consumer goods. The aim of the invention is to enhance the functionality and increase usability due to the possibility of not only removing it. storing, but also introducing buttons. When the openings of the outer and inner cups are aligned, they form an opening for filling the cavity of the device of the buttons 1. To remove the button 1, the bolts are behind the protrusion 13 and push it onto the button 1 with a forward movement. The lower part of the slot 8 has a sharp edge that goes under the head of button 1, and the elevation angle of the cone 9 removes button 1. To install button 1, insert its head 1/4 into the rectangular longitudinal slot 8, holding the fingers of the other hand slightly embed it in the board material for retention. 5 il.

The invention relates to consumer goods, in particular, to pushbutton-devices for mounting and removing drawing and cantr buttons used for securing announcements on stands, drawing paper on boards of designers' panels, and so on.

A known structure for removing stationary buttons, comprising spring strikers with several sleeves for fitting buttons of various sizes and spring cheeks to hold buttons in them.

The closest in technical essence to the claimed is a device for removing and storing stationary buttons, which contains a hollow container consisting of two parts with openings that are oppositely directed and connected to each other.

The disadvantages of this device are:

difficulty of button removal, a large number of manipulations;

the difficulty of installing the buttons.

The purpose of the invention is to expand the functionality and increase usability due to the possibility of not only removing, storing, but also introducing buttons.

This goal is achieved by the fact that in a device for removing and storing stationary buttons containing a hollow container consisting of two coaxially mounted oppositely directed and connected with each other parts with holes, both parts of the hollow container are made in the form of coaxially arranged and facing each other the ends of the glasses in which the hole is located n & lateral cylindrical VJ

surface and is a longitudinal slot directed from the end, a width chosen equal to the diameter of the cap of the button, the inner surface of the bottom of the outer sleeve is made in the form of a cone with a lifting angle selected within 5-15 ° and having a radial groove. a width equal to or greater than the thickness of the button stem, and a length selected 5–15% more than the radius of the button's head, and a pin fixed at the top of the cone, the height of the outer cup is greater than the height of the inner one by an amount equal to the thickness of the head of the button The bottom has a central opening for placing the pin and, on the outer surface at the bottom, a protrusion annular with knurling along the cylindrical surface, which interacts with the end face of the outer cup.

Figure 1 shows the device a General view: figure 2 is a view along arrow a but figure 1; on fig.Z internal stakach; figure 4 is an external glass with a mounting stud; figure 5 is a device ready for the syrup of buttons.

The device for removing and storing the stationary buttons 1 comprises a hollow container consisting of two coaxially mounted, counter-directed and interconnected parts.

Both parts of the hollow container are made in the form of ends 2 and 3 of glasses 4 and 5 with openings 6, 7. coaxially and facing each other, respectively, located on the lateral cylindrical surfaces of glasses 4 and 5 each and representing a longitudinal slot 8, directed from the end 3, the width chosen equal to the diameter of the head of the buttons 1, the inner surface of the bottom of the outer cup 4 is made in the form of a cone 9 with a lifting angle selected in the range of 5-15 °. and having a central groove 8 with a radial groove 10 with a width equal to or greater than the thickness of the button 1, and a length chosen 5-15% more than the radius of the head of the button 1. and fixed at the apex of the cone pin 11 4 is greater than the height of the inner cup 5 by an amount chosen equal to the thickness of the hat of the button 1. The latter has a central hole 12 for accommodating the stud 11 and, on the outer surface at the bottom, a protrusion 13 that is annular with knurling along the cylindrical surface 13. about 4 cups.

The assembly of the device is as follows.

A pin 11 is inserted into the outer cup 4 in the center of the apex of the cone 9. To eliminate unscrewing, for example, a core (see Fig. 1).

A sufficient condition for the assembly is screwing together the glasses 4, 5 among themselves when aligning the holes 6 and 7 of the outer 4 and inner 5 glasses, an opening 15 is created for filling into the cavity of the device 8-12 buttons, turning the inner glass 5 behind the protrusion 13 with knurling relative to the outer The cup 4 closes the opening 15, which prevents the buttons 1 from falling out of the internal volume of the container and storing them.

The operation of the device is as follows.

To remove the buttons 1, use three fingers to take the device by the knurl 13 with a knurling along the cylindrical surface (Fig. 1) and slide it onto the button 1 with a forward movement. The conical inner surface of the outer cup 4 in the form of a cone 9 with a lifting angle in the range of 5-15 °, and having a radial groove 10 located in the center of the slot, allows you to remove the button 1 and push it into the internal volume of the device through the slot 8. The lower part The slot 8 has a sharp edge that goes under the head of the button 1, and the angle of elevation of the cone 5-15 ° ensures the removal of the button 1 (raising the button) during the forward movement of the device without tilting it.

The radial groove 10, located in the center of the hole 7, having a width not less than the maximum thickness of the leg of the button 1, is 5–15% longer than the radius of the button 1 and ensures that the button 1 can freely pass into the internal volume of the device.

To install button 1, for example, on the drawing board, it is necessary to insert its head 1/4 into the rectangular longitudinal slot 8, holding the fingers of the other hand, slightly embed it in the material of the board to be held.

A sufficient condition for the installation is to press its head with the outer surface of the outer cup 4, while the device can be held with three fingers or interact with the palm of the hand, which increases the contact area by an order of magnitude and increases the force of the pushing leg 1.
