Violin shoulder rest positioner

Abstract

A violin shoulder rest auxiliary device can assist ordinary shoulder rest and be firmly placed on a violin, and is a violin shoulder rest positioner. Two-way telescopic devices are connected with pull rods at both ends, or one-way telescopic devices are connected with pull rods at both ends, so that the pull rods at both ends become an integral pull rod. The two end bending point end screw caps of the integral pull rod are connected with the fixed screw rods of the two end clamping horns of the shoulder rest, and the distance between the two end clamping horns of the shoulder rest is adjusted and controlled by the telescopic device, so that the shoulder rest can be installed on the violin at a suitable position according to the use habit of a player and is firmly placed on the violin and is not easy to fall off. The violin shoulder rest positioner with a few dollars is assembled on the ordinary shoulder rest with a few dollars, and the use performance is improved in quality and is not inferior to the high-end shoulder rest with a high price. Ordinary people can use the violin shoulder rest with the shoulder rest positioner which is cheap and good.

Description

Technical Field:

[0001] This invention relates to an auxiliary device for a violin shoulder rest, which is a device that can stabilize the violin shoulder rest in a suitable position on the violin, and more particularly to a violin shoulder rest locator. Background technology:

[0002] Currently available violin shoulder rests lack a stable positioning device that can securely hold the violin in a suitable position. High-end shoulder rests are too expensive and can only be installed in a fixed position on the violin, failing to meet the usage habits of every player. Popular violin shoulder rests, due to the elastic material used, have clips at both ends that tend to flare outwards, resulting in unstable positioning during use. The shoulder rest can easily detach from the violin, causing accidental damage and affecting performance. Summary of the Invention:

[0003] In order to provide a violin shoulder rest that is inexpensive and suitable for the different habits of each player, and to ensure that the shoulder rest is stably positioned in the appropriate position on the violin body, I invented a violin shoulder rest positioner. It uses a unique adjustable lever with screw caps at both ends to lock the latch posts at both ends of the shoulder rest, and uses a telescopic device to position the distance between the latches at both ends, so that the shoulder rest is stably positioned in the appropriate position on the violin body.

[0004] The violin shoulder support locator of this invention, with its bidirectional telescopic shoulder support locator, employs the following technical solution: It features a front-facing screw cap and a back-facing screw cap of the same diameter, aligned at a suitable distance of approximately 2cm. The two screw caps are connected and fixed on both sides by an outer frame, forming a bidirectional telescopic device. Two pull rods are provided. One pull rod has a screw thread at one end that matches the front-facing screw cap; the other end bends past the diameter of the shoulder support end's locking screw rod, with a screw thread at the extended end and a screw cap fixed to the locking screw rod. The other pull rod has a back-facing screw thread at one end that matches the back-facing screw cap; the other end of the other pull rod bends past the diameter of the other end's locking screw rod, with a screw thread at the extended end and a screw cap fixed to the other end's locking screw rod. When the two pull rods are connected into a single integral pull rod by the bidirectional telescopic device, the length of both ends of the integral pull rod can be adjusted arbitrarily between 18.5cm and 20cm, thus forming a bidirectional telescopic violin shoulder support locator.

[0005] The shoulder support locator of the one-way telescopic device has a snap-on nut and a bushing with the same shape as the nut. The nut and bushing are aligned at a suitable distance of approximately 2cm. They are then connected and fixed to the outside of the nut and bushing with an outer frame to form the one-way telescopic device. Two pull rods are provided. One end of one pull rod has a screw thread that matches the nut, and the other end bends past the diameter of the retaining rod at one end of the shoulder support. The extended end has a screw thread and is fixed to the retaining rod with a nut. The upper section of the tie rod has a screw thread at one end that passes through the bushing hole, and an inner frame baffle on the screw thread at one end. An outer frame baffle is also provided on the tie rod on the outer frame section. The other end of the tie rod is bent over the diameter of the screw rod by the other end clip. The extended end has a screw thread and is fixed to the screw rod of the other end clip with a nut. When the two tie rods are connected into a whole tie rod by a one-way telescopic device, the length of both ends of the whole tie rod can be adjusted arbitrarily between 18.5cm and 20cm, becoming a one-way telescopic violin shoulder support positioner.

[0006] The beneficial effects of this utility model are that by using a violin shoulder rest positioner that costs only a few dollars and attaching it to an ordinary shoulder rest that costs only a few dollars, the efficiency of its use is significantly improved. The stability of the shoulder rest attached to the violin body is comparable to that of high-end shoulder rests, preventing it from falling off the violin body. Furthermore, the position of the shoulder rest on the violin body can be adjusted arbitrarily according to the player's personal habits, while maintaining stability. This feature is superior to high-end shoulder rests that cost exorbitantly priced. It enables the general public to use affordable and high-quality violin shoulder rests equipped with shoulder rest positioners. Attached Figure Description
