Description

The invention relates to mechanical engineering, to a device for storing washers and nuts.

A device is known for storing nails, screws, nuts, etc., see the upper figure on page 233 in the book: Tools and Devices: Encyclopedia of household savvy. / Aut. sost. V.M. Satsuta, E.V. Malashevich, I.M. Starchenko; The artist. V. Senchenko. 2nd ed. Minsk: “Belarus Entsiklapedyya”, 1997, 281 p. This device can be used to store nails, screws, nuts, washers, and other parts. This device is a set of flat cans strung on a common axis of rotation. Moreover, for each such can, a part of the upper lid is left, an axis fixed in a metal bracket is passed through it and the lower lid. To easily rotate the cans, washers are laid between them. It is convenient to take cans of the same size.

The matching features of this device and the claimed invention are as follows. This device is intended, inter alia, for storing washers and nuts; it protects against possible loss of washers and nuts when exposed to vibrations and other disturbances.

The disadvantages of this device are as follows: it is difficult to select a washer (nut) of the required size from this device if there are a lot of washers (nuts) and they are of different sizes.

A device for storing washers and nuts (that is, parts having a hole) is known, see on page 233 the second figure below in the book: Tools and Accessories: Encyclopedia of household savvy. / Aut. sost. V.M. Satsuta, E.V. Malashevich, I.M. Starchenko; The artist. V. Senchenko. 2nd ed. Minsk: “Belarus Entsiklapedyya”, 1997, 281 p. This device is adopted as a prototype. This device is a straight, vertically located rod, the lower part of which is fixedly mounted on the base. The rod has a circular cross section, the diameter of which is less than the diameter of the hole in the washers and nuts, which are intended for storage on this device. The length of the rod is chosen so that it is convenient to place more than five washers or nuts on this rod. The rod is located vertically, the lower part of the rod is fixedly mounted on the base; nuts and washers "string" onto this shaft; under the influence of their own weight (and the weight of the upstream parts), these parts remain "strung" on this rod and are not lost.

The matching features of this device and the claimed invention are as follows. This device is designed to store parts with a hole (washers, nuts, etc.). It has a rod of circular cross section, the diameter of this rod is less than the diameter of the hole in the washers and nuts, which are intended for storage on this device; the length of the rod is chosen so that it is convenient to store more than five washers and nuts. This rod (guide) is fixed at one end to the base.

The disadvantages of this device are as follows. To take the selected part (washer or nut), remove the upstream parts (nuts or washers) from the rod; these parts need to be temporarily located somewhere, and then returned. During these operations, any part may be lost. The likelihood of losing any part increases markedly if the work is carried out under conditions of vibration or in zero gravity.

The objective of the invention: to provide the ability to remove from the device the selected washer (nut) without removing from the device other washers (nuts).

This problem is solved in that the guide (the rod onto which the washers are "strung") is shaped like a circle. Moreover, the guide has a cut in the middle part, i.e. The guide consists of two parts. In the area of the cut, the end zones of the parts of the guide have “narrowing”. Both parts of the guide are fixedly fixed to the base. In the cut region, the end zones of the guide parts are pressed together by the elastic forces of the auxiliary elastic element.

The essence of the invention lies in the fact that the guide (the rod onto which the washers (nuts) are "strung") resembles a circle in shape. Moreover, in the middle part the guide has a cut, i.e. the guide is composite, it consists of two parts. In the area of the cut, the end zones of the parts of the guide have “narrowing”. Both parts of the guide are fixedly fixed to the base. In the cut region, the end zones of the guide parts are pressed together by the elastic forces of the auxiliary elastic element.

The technical result of the invention is that to remove the desired washer (nut) from the device, it is not necessary to remove other washers (nuts) from the device.

The end parts of the guide parts, at the point of contact, are made tapering (the diameter of the cross-section of the rod (part of the guide) in this zone decreases as it approaches the end part). Moreover, the tapering part of these areas of the guide is, for example, a truncated cone, or part of the surface of a sphere or other surface. This is done, in particular, so that when removing the necessary washer (nut) from the device (and also installing it on the device), the desired location of this washer (nut) on the device could be fixed not only visually, but also on the basis of other sensations , - the necessary washer (nut) before its removal will be in the “recess”. The location of the “groove” can be found by touch with your fingers or by moving the desired washer (nut) along the guide without looking at the device itself for temporary storage of washers and nuts. Then, having shifted the desired washer (nut) into the “recess” and pushing the other washers (nuts) apart, apply force to the elements 2 and 3, push the end parts of the elements 2 and 3 apart from each other until a clearance sufficient for removing the desired washer (nut). After removing the desired washer (nut), the elements 2 and 3 are released, and they are compressed against each other due to the elastic forces of the additional elastic element 4. If the washer (nut) is thin enough, then you may not need to apply force to the elements 2 and 3, but it will be enough to apply force to the washer (nut) in the desired direction. (The same procedure applies when installing the washer (nut) on the device.)

In FIG. 1 shows a device for temporary storage of washers and nuts, top view; in FIG. 1 shows a device without washers and nuts placed on it.

In FIG. 2 shows the device at the time when the “washer” 5 is “inserted” to place it on the device (or the “washer 5” is “taken out”).

In the figures, the following details are indicated.

1 - base.

2 - one part of the guide fixedly mounted on the base.

3 - another part of the guide, fixedly mounted on the base through the elastic element 4.

4 - an elastic element, for example, in the form of a curved flat spring.

In the figures, the elastic element 4 is shown conditionally in the form of a curved flat spring. The conditions under which the characteristics of the elastic element are selected are given at the end of the description of the invention.

In fact, the length of the parts of the guide 2 and 3 can be longer than shown in the figures (in the figures, the length of these parts and other sizes are chosen so as to clearly show the device of this device and at the same time fit into the paper sheet formats).

To remove the desired washer (nut) from the device proceed as follows. Select the desired washer (nut). Moving adjacent washers and nuts to the right or left, the selected washer (nut) is brought to the “recess” formed at the contact point of the ends of elements 2 and 3. The remaining washers and nuts are moved away from this “recess” and, using force, the selected washer is removed from the device (nut). If necessary, it is possible to deform the elastic element 4 by applying force to the part 3 until a gap is formed between the ends of the elements 2 and 3, sufficient to remove the selected washer (nut) from the device.

To install a washer (nut) on the device, proceed as follows. Visually evaluate the hole in the washer (nut) and make sure that the device is suitable for such washers (nuts). Washers (nuts) are moved away from the “vymeka” between the ends of the elements 2 and 3. Applying force to the washer (nut), they try to “shove” it between the end parts of the elements 2 and 3. If necessary, apply force to the end part of the part 3, while deforming the elastic element 4. If necessary, before installing another washer (nut) on the device , the remaining washers (nuts or part of them) should be shifted “to the right” (or “left”) from the contact zone of elements 2 and 3.

For convenience, the outer diameter of the section of parts 2 and 3 is made the same.

The device can be mounted on a portable base, i.e. the device can be portable and can be mounted in the right place.

In addition to washers and nuts, other parts that have holes can be placed on the device.

Apparently, for massive washers and nuts (respectively having a large mass and a large hole diameter in them), a large diameter rod should be used in the manufacture of the device (to reduce the mass of the device, in this case, a rod in the form of a pipe can be used in the manufacture). And for small washers and nuts (respectively having a small mass and a small hole diameter in them), a rod with a small diameter cross section should be used in the manufacture of the device.

It is convenient to make a guide from a round rod. But the cross section of the rod may be different, for example, in the form of a regular hexagon, etc.

The total number of washers (nuts) installed on the device is selected so that it is possible, by moving parts to the right (left), to select and remove the desired part from the device.

Thus, the device for temporary storage of washers and nuts has a rigid guide fixed in the form of a rod, for example, of constant circular cross section, fixed to the base. The cross-sectional diameter of this guide is less than the diameter of the hole in the washers and nuts that are supposed to be stored on this device. The guide is composite, it consists of two parts. The length of each part of this guide is more than five thicknesses of the above washers and nuts. The guide consists of two parts, and these parts of the guide are pressed against each other by their end parts. Parts of the guide form a curve close in shape to a circle. This curve is located in the horizontal plane. Parts of the guide are approximately the same length. Those. the contact zone of the end zones of the guide parts is approximately the same distance from the fastening zones of the other end zones of the guide parts. The ends in the contact area of the two parts of the guide are made tapering when approaching these ends. Moreover, the tapering part of these areas of the guide is, for example, a truncated cone, or part of the surface of a sphere or other surface. The end contact zones of the guide parts are pressed together using an auxiliary elastic element located near the fastening zone of one part of the guide to the base.

In the figures, the elastic element 4 is shown conditionally in the form of a curved flat spring. When choosing the parameters of the elastic element 4, the following conditions should be taken as a basis. The end parts of sections 2 and 3 are pressed against each other due to the elastic forces of the material of the elastic element 4. Moreover, if external forces do not act, the end parts of sections 2 and 3 should be in contact. And the application to the end of the element 3 in the direction “to the right” (see the figures, that is, from the end of the element 2) of a force of approximately 5 N should lead to the formation of a gap between the end parts of the elements 2 and 3 of 2 ... 5 mm . The device of the elastic element 4 should be such that applying a force of up to 10 N to the end face of the element 3 in any direction would not cause the end part of the element 3 to deviate from the plane in which the mid lines of the elements 2, 3 were located before applying the load to the element 3, more 2 mm. (If the device is designed to store large nuts with a large height, then the size of the formed gap between the ends of the parts 2 and 3, with the application of force to the end of the element 3, should be increased.)

Parts of the guide may be coated with, for example, a “rubber sheath” to reduce the “noise” effect.

The length of the tapering part of the end zone of each part of the guide is approximately equal to the radius of the section of this part of the guide.

So, the guide is made compound (it consists of two parts, which are pressed together by their end zones). To remove the desired washer (nut) from the device, it is not necessary to remove other washers (nuts) from the device, they only need to be moved. Select the desired washer (nut). If necessary, other washers (nuts) (or part thereof) are moved through the contact area of the end zones of the guide parts to another part of the guide without removing them from the device. Then, the desired washer (nut) is brought to the contact area (the remaining washers (nuts) are moved away from this area) and removed from the device. Thus, a causal relationship between the object of the invention and the technical result of the invention is manifested.
