Description

The invention relates to the field of devices that provide stability held in the hand of portable electronic devices (PES) [F16M 13/00, A45F 5/00, H05K 5/00].

Traditional holders for portable electronic devices (smartphones, pocketbooks, e-books, communicators, mobile phones) are difficult to hold with one palm for a long time if the user is engaged in any physical activity, such as sports training, and his work requires the use of two hands. However, the need for constant monitoring of information on the PES screen may be a prerequisite. In this case, there may be a risk of the PES falling and damaging it. In addition, PES can be easily forgotten and lost, which is also undesirable. There are technical solutions that allow you to mount the phone on the user's shoulder or wrist, however, in this case, it becomes necessary to use a second hand to operate the touch screen, which may also not be feasible.

Thus, there is a need to solve the above problems with the prior art.

An ERGONOMIC ACCESSORY FOR USE WITH A PORTABLE ELECTRONIC DEVICE [US 20120063066 A1, publ.: 15.03.2012], CASE FOR SMARTPHONES [RU 130808 U1, publ. 08/10/2013], made in the form of tapes for fastening to the back surface of a portable electronic device or case, with the possibility of releasing the thumb to work with the touch device.

The main common drawback of these devices is the permanent fixation of the PES on the user's palm.

Known from the prior art is a UNIVERSAL MOBILE PHONE CASE AND PROTECTIVE DEVICE [US 9991921 B1, publ.: 06/05/2018], having protruding elastic rings that soften the case and act as bumpers when a portable electronic device is dropped, protruding bumpers / the rings can also support straps so that portable electronic device cases can be easily and safely held in the finger, wrist or neck.

The disadvantage of this analogue is the unstable fixation of the PES on the user's hand without the possibility of working with the PES by the hand in which it is attached.

Known CELL PHONE UNIT ON HAND [JP 2009268041 A, publ.: 11/12/2009], including a holder having a part for holding a mobile phone, and a holder fixed with three or four flat screws, combined and attached to the hand, an elastic bracelet, the holder and bracelet are combined by attaching and fixing each other with screws, the bracelet is attached to the hand near the wrist through the hand and wrist with the help of the bracelet's elasticity.

The disadvantage of this analogue is the permanent fixation of the PES on the user's hand without the possibility of working with the PES by the hand in which it is attached.

The prior art WRIST SMARTPHONE [KR 20138526 A, publ. December 26, 2012], having an elastic band with a rotating rod, which includes a connecting protrusion formed on its outer peripheral surface and a fastening part formed on the upper side of the connecting protrusion. A case formed on the upper side of the rotating rod and configured to protrude the headphone cord from both sides thereof, and a case into which a smartphone can be inserted and fixed. According to the present invention, by attaching a smart phone to a case and connecting it with a band for wearing on a user's arm, it can be made possible to rotate to adjust the angle according to the user's field of view.

The disadvantage of this analogue is the limitation of functionality, without the possibility of working with the PES hand, in which it is attached due to the inconvenient location on the shoulder.

The prior art DEVICE FOR QUICK AND CONVENIENT USE OF CELL PHONE [RU 2005100989 A, publ. 06/20/2006], containing a longitudinally placed cell phone, characterized in that it contains a holder case, closed with a cap, braid or elastic band using any appropriate fastener, such as Velcro, which is attached to the wrist with one strap (bracelet), two straps (bracelets), or strap and bracelet.

The disadvantage of this analogue is the permanent fixation of the PES on the user's hand without the possibility of working with the PES by the hand in which it is attached.

Known WRIST HOLDER FOR MOBILE DEVICES [RU 205078 U1, publ. 08/10/2013], contains a support platform with elongated holes in the corners for fastening it with two straps on the forearm of a person's hand. A rack having a flat base is attached to the platform. The rack has an external thread in the upper part and a nut with a reciprocal thread. The wrist holder is equipped with two fasteners and in the form of corners. The lower one of the holders is rigidly fixed on the base of the rack, and the upper one has a clamp for putting it on the rack with the possibility of longitudinal movement along it and fixing it with a nut. Ensuring the possibility of fixing various mobile devices in the wrist holder without rearranging their cases is achieved due to the fact that the holder contains a support platform for mounting on a person’s hand using two straps with a Velcro fastener and a rack attached to the support platform, which has a flat base with holes for screw fastening to the support platform, an external thread in the upper part of the rack and a nut with a mating thread, as well as two fasteners, the lower of which is rigidly fixed to the base of the rack, and the upper one is equipped with a clamp for putting it on the rack with the possibility of longitudinal movement along it and fixing nut

The disadvantage of this analogue is the permanent fixation of the PES on the user's hand without the possibility of working with the PES by the hand in which it is attached.

The closest in technical essence is a SPECIAL HOLDER FOR MOBILE PHONE AND ACCESSORIES [US 10284249 B2, publ. 05/07/2019], which consists of a body or bag of the device, additionally consisting of a closed lower end of the bag, a pair of sides of the bag, an open end; elastic belt; ring for an additional accessory / attachments; adjustable bracelet and D-ring; finger strap; at least one optional accessory snaps onto the ring; means for attaching removable additional accessories/nozzles to the ring; and means for removably attaching the strap to the user's wrist, in which a dedicated palm-mount cell phone and accessory holder provides an aesthetic and secure way to hold and protect electronic devices.

The main technical problem of the prototype is the use of a stationary platform with permanent fixation of the PES on the user's palm, due to the volumetric size and fastening to the fingers of the user's hand - there is no possibility of working with the PES by the hand in which it is attached. In addition, during physical training, for example, running, there is a risk of damage to the PES due to its location directly on the user's palm.

The main objective of the invention is to eliminate the disadvantages of the prototype.

Implementation of the invention.

The retractable wrist holder for portable electronic devices is a mount for a portable electronic device to the forearm of the user's hand, consisting of a rectangular stationary platform 1, designed to be mounted on the user's forearm. Sides 9 are made along two longitudinal and one transverse sides of said stationary platform 1, which serve to ensure the rigidity of the platform 1 structure.

At the base of the stationary platform 1, a T-shaped groove 6 closed from both ends is made along the length, in which a longitudinal rail 5 is movably mounted, while for mounting the said rail 5 in the groove 6, protrusions are made at one of its ends with the possibility of their placement in the horizontal part T -shaped groove 6.

A slot 10 is made in the middle along the rail 5.

In said slot 10, a retractable platform 4 is movably mounted, made of a rectangular shape with a length and width that allows the said retractable platform 4 to be placed between the sides 9 of the stationary platform 1.

The retractable platform 4 is mounted to the rail 5 with the ability to move along the slot 10 using a docking element 17, consisting of a rod and a cap, while the docking element 17 with its end face through the slot 10 is mounted behind to the retractable platform 4, and the cap serves to hold the mentioned retractable platform 4 on rail 5.

In the stationary platform 1, in one of the corners on the side of the part of the mentioned platform 1, made without board 9, a recess is made in the form of a compartment 11 with an external slot located at the end of the mentioned part of the stationary platform 1. In the compartment 11, a spring-loaded locking mechanism 8, made in in the form of a plate with a triangular protrusion pivotally mounted on a pin 12. The plate of the spring-loaded locking mechanism 8 is made spring-loaded by means of compression of the spring 14, mounted in the rear part of the spring-loaded locking mechanism 8 between the plate of the mentioned spring-loaded locking mechanism 8 and the wall of the compartment 11 with the help of fastener 15.

On the rear wall of the retractable platform 4 with the possibility of passing through the slot in the compartment 11 and entering the compartment 11 with further interaction with the triangular protrusion of the plate of the spring-loaded locking mechanism 8, a locking element 18 is mounted, made in the form of a pin. Stationary platform 1 has a mount for external holders 16, namely belt 3.

On the outside of the retractable platform 4, holders 7 are mounted, made of U- or L-shaped, as well as clothespins with the ability to hold a portable electronic device 2 when it is placed on a retractable platform 4. The said holders 7 can be made in any number, as well as movable with the ability to adjustments for a specific amount of PES.

A belt 3 is mounted to the back of the stationary platform 1, made with the possibility of covering the said belt 3 of the user's forearm for quick placement of the described technical solution on the hand and its removal. Said belt 3 may be closed or provided with fasteners and made of elastic material. Belt 3 can be equipped with a length regulator. Fasteners can be made in the form of, for example, buckles, fastex fasteners, Velcro textile tapes, etc.

The retractable wrist holder for portable electronic devices is used as follows.

In the initial position, the retractable wrist holder is fixed to the back side of the user's forearm with the help of a belt 3, while the retractable platform 4 is fixed on the stationary platform 1, the rail 5 is completely in the groove 6 of the stationary platform 1, and the fixation element 18 is engaged with the rear side of the triangular protrusion of the plate of the spring-loaded locking mechanism 8. The portable electronic device 2 is placed on the retractable platform 4 and fixed on it with the help of holders 7 (see Fig. 6).

To move the portable electronic device 2 into the user's palm, the user mechanically with his second hand acts on the end of the portable electronic device 1 from the side of the forearm or performs an inertial effect on the holder 7 with a sharp wave of the hand on which it is mounted. As a result of this action, the retractable platform 4 slides along the surface of the stationary platform 1, the rail 5 slides along the groove 6 of the stationary platform 1, the docking element 17 slides into the slot 10 of the rail 5, and the fixation element 18 slides along the rear side of the triangular protrusion of the plate of the spring-loaded locking mechanism 8, which, turning on the pin 12, simultaneously compresses the spring 14 with its rear part until the fixation element 18 overcomes the top of the triangular protrusion of the spring-loaded locking mechanism 8 plate. 5 extends to its full length from the slot 6 of the stationary platform 1, the docking element 17 reaches the edge of the slot 10 of the rail 5, and the portable electronic device 2 reaches the user's palm (see Fig. 7). Simultaneously with the release of the fixation element 18 from the compartment 11, the plate of the spring-loaded locking mechanism 8 returns to its original position by the spring 14.

Moving to the initial position of the holder is carried out in reverse order.

In 2021, the author of the invention made, in accordance with the above description, a sample of a retractable wrist holder for portable electronic devices. The manufactured sample of the retractable wrist holder was tested to confirm the claimed technical result by conducting several similar experiments:

- the first option: work with a portable electronic device located only in the user's palm (prototype);

- the second option: the use of a retractable wrist holder using the function of moving the device into the user's palm.

The use of a retractable wrist holder without using the function of moving the portable electronic device 2 into the user's palm according to the first variant showed that when using a telephone as a PES, to answer an incoming call, it is required to bend the arm at the elbow and raise the arm by more than 90 ° relative to its natural position to ear, which is unnatural and causes discomfort and fatigue of the hand during a long conversation.

The results of the second variant of using the proposed device made it possible to establish that the spring-loaded locking mechanism 8 does not allow the retractable platform 4 to jump out of the stationary platform 1 while walking, running. And only after a wave of the hand with its fixation, the spring-loaded locking mechanism 8 is "unlocked", and the retractable platform 4 with the portable electronic device 2 is transferred to the palm of the user's hand. At the same time, the movement of the retractable platform 4 is limited and the portable electronic device 2, having moved into the palm of the user's hand, is fixed, which allows it to be taken into the palm of the hand, simply by squeezing the fingers.

Thus, the claimed device has significant advantages in comparison with analogues, and the experiments carried out proved the achievement of the claimed technical result - an increase in the ease of wearing and quick movement of the PES from the storage location located on the forearm to the user's palm.
