AI Technical Summary

Technical Problem

Open-pored compressible and expandable foam earplugs are difficult to insert due to the need for manual compression before insertion, especially with cold, vibrating, or unclean hands, leading to challenges in safe and neat placement into the ear canal.

Method used

An earplug device with a magazine, compressor, and conveyor system that facilitates the insertion of foam earplugs by compressing and guiding them into the ear canal, featuring a rotatable circular or cuboid magazine, spring-assisted ejection, and a flexible tape for compression, along with an adjustable insertion mechanism.

Benefits of technology

Enables safe and neat insertion of foam earplugs into the ear canal, improving ease of use and ensuring consistent placement without manual compression, even in challenging conditions.

Description

[0001] The invention relates to an earplug insertion device.

[0002] Open-cell compressible and expandable foam earplugs are often difficult to insert, especially if the inserter has cold, numb fingers due to vibration, or dirty hands, as these earplugs must be compressed before insertion so that they can fit into the ear canal and then expand again.

[0003] The object of the invention is to improve the state of the art and in particular to provide a device which makes it possible to insert open-pore compressible and expandable earplugs made of foam from a magazine into an ear canal in a simple and clean manner.

[0004] The problem is solved by the claims.

[0005] Earplug insertion device comprising a magazine suitable for receiving preferably open-pored, compressible and expandable foam earplugs, as well as a compression device in which a compressible and expandable earplug is compressible lengthwise, and an earplug conveying device for inserting the earplug from the magazine into the compression device and then into the ear canal.

[0006] The earplug insertion device according to the invention preferably comprises a magazine which preferably comprises a rotatable circular shaped body having bores with a depth and diameter of at least the length and diameter of an earplug, wherein the earplugs are arranged in a circle in the magazine.

[0007] Another embodiment of the magazine of the earplug insertion device according to the invention would be a magazine consisting of a cuboid-shaped body in which the earplugs are arranged one above the other and can be conveyed from bottom to top via a conveyor device. The conveyor device could be a spring arranged beneath the earplugs, which successively pushes the earplugs upward as each earplug is removed. Another conveyor device would be an endless conveyor, preferably running in an elliptical shape.

[0008] The earplug insertion device according to the invention has a compression device which preferably has a sleeve which is open at the top and in which the earplug can be conveyed with an insertion piston which preferably has the shape of a concave plate at its end, with which it comes into positive contact with the earplug.

[0009] The earplug insertion device according to the invention can also have a sleeve open at the top and at the ends as a compression device, in which the earplug is inserted with a flexible band, preferably made of metal or Teflon, which comes into positive contact with the earplug and encloses the earplug and compresses the earplug by pulling on the band.

[0010] The earplug conveying device preferably has a conveying piston which conveys the earplug from the magazine into the compression device and another piston, the insertion piston, which conveys the compressed earplug from the compression device into the ear canal.

[0011] The adjustment device according to the invention can also preferably have an adjustment device which has an adjustment device at the outlet of the earplug insertion device, i.e. at the point at which the earplug is inserted into the ear canal, which adjustment device preferably has a screw thread in order to change the distance between the outlet of the earplug insertion device and the adjustment device to the ear canal, preferably to lengthen it, in order to thus adjust the distance by which the earplug can be inserted into the ear canal. Figures Fig. 1 Fig. Figure 1 shows the entire earplug insertion device 1 in lateral cross-section. The earplug feed device 1 has a feed piston 3 with a thumb-pressing plate, which feeds the earplug from the magazine into the compression device, and another piston, the insertion piston 2, which feeds the compressed earplug from the compression device into the ear canal. The compression device is operated by the compression lever 4. Furthermore, an adjustment device 5 can be seen, which has an adjustment device at the outlet of the earplug insertion device, i.e. at the point at which the earplug is inserted into the ear canal, which adjustment device preferably has a screw thread in order to change the distance between the outlet of the earplug insertion device and the adjustment device to the ear canal, preferably to lengthen it, in order to thus adjust the way in which the earplug can be inserted into the ear canal. Fig. 2 Fig. 2 shows the compression device with the feed piston 3 which presses an earplug 12 into the compression device in the form of a flexible metal compression band 10 which is held together by a metal clamp 11 and can be pulled downwards in order to compress the earplug 12. Fig. 3 Fig. 3 shows a rotatable circular molded body 6 having bores 7 of depth and diameter at least equal to the length and diameter of an earplug, wherein the earplugs are arranged in a circle in the magazine 6, wherein the circular molded body 6, a rotary magazine 6 with earplug receiving openings 7, rotates about a rotary shaft 8. Fig. 4 Fig.4 shows an adjusting device 5 having a screw thread 9 for changing, preferably lengthening, the distance between the outlet of the earplug insertion device and the adjusting device to the ear canal, in order to adjust the distance by which the earplug can be inserted into the ear canal.
