Description

Technical Field

[0001] The present invention relates to the technical field of safety devices, and more particularly to an anti-lost device for elderly dementia patients. Background Art

[0002] Alzheimer's disease is a degenerative disease of the central nervous system characterized by progressive memory loss and loss of cognitive function. Its pathological characteristics are the formation of senile plaques and neurofibrillary tangles. With the aging of the global population, the incidence of Alzheimer's disease is also increasing year by year. This disease is a common and frequently occurring disease among the elderly. It is a chronic degenerative disease. The main clinical symptoms include a significant decline in memory, especially severe forgetfulness of recent events, as well as forgetfulness of distant events. There may also be mental confusion, difficulty in perception, and decreased comprehensive ability. Severe Alzheimer's patients may completely lose their ability to move and cannot take care of themselves. This not only brings great psychological and economic pressure to patients and their families, but also imposes a heavy burden on society. Therefore, if there is no special person to take care of them outdoors, they will often get lost.

[0003] At present, the way to prevent Alzheimer's patients from getting lost is generally by hanging information tags on their clothes, but this method is generally ineffective, or by wearing a bracelet locator on their hands, but sometimes some Alzheimer's patients may resist wearing bracelets, and the unconscious operation of the elderly may cause the bracelet to fall off. Therefore, in order to further avoid these situations, we propose an anti-loss device that is more suitable for Alzheimer's patients, breaking through the limitations of traditional bracelets or hanging devices, improving the comfort and stability of patients wearing, so as to solve the problem of patients getting lost due to memory loss and loss of sense of direction, and reducing the care burden of family members.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Embodiment 1 The anti-loss device for patients with Alzheimer's disease proposed by the present invention is further described, comprising a shoe body 100, a sole 101 is arranged at the bottom of the shoe body 100, and the shoe body 100 and the sole 101 are sutured and connected, the sole 101 comprises a heel portion 102 and a forefoot portion 103, the middle of the sole 101 is inwardly recessed to form a navicular surface 104, an internal plate 105 is detachably arranged in the heel portion 102 and the forefoot portion 103, a positioning mechanism 200 is arranged at the position of the internal plate 105 located at the navicular surface 104, and a locking mechanism 300 is arranged at the position of the internal plate 105 located at the forefoot portion 103;

[0036] Since patients with Alzheimer's disease are often not conscious, they often get lost when going out. The existing technology mainly prevents patients with Alzheimer's disease from getting lost by hanging information tags on their clothes, but this method is generally ineffective and is easy to fall off and difficult to carry. Alternatively, they wear a bracelet locator 502 on their hands, but sometimes, the unconscious operation of the elderly may cause the bracelet locator 502 on the arm to slip off. The present invention adds a hidden built-in plate 105 in the sole 101, and the built-in plate 105 is provided with a locator 502, so that the present invention is not easy to be damaged, which effectively improves safety, durability and concealment.

[0037] The positioning mechanism 200 includes an inserting piece 201 disposed in the built-in plate 105, a positioning piece 202 matching the inserting piece 201 is disposed on the navicular surface 104, a resisting piece 203 is disposed in the positioning piece 202, the resisting piece 203 and the inserting piece 201 cooperate to unlock the positioning mechanism 200, the locking mechanism 300 includes a locking piece 301 disposed in the built-in plate 105, a clamping piece 302 matching the locking piece 301 is disposed in the forefoot portion 103, the locking piece 301 and the clamping piece 302 cooperate to fix the built-in plate 105, and a reinforcing piece 303 is also disposed in the locking piece 301;

[0038] Depend on Figures 1 to 5 It can be seen that the present invention further limits the structure of the built-in plate 105, by arranging a locking mechanism 300 and a positioning mechanism 200 in the built-in plate 105, specifically, the head of the built-in plate 105 can be locked through the cooperation of the positioning member 202 and the plug-in member 201, and the tail of the built-in plate 105 can be fixed by the cooperation of the locking member 301 and the clamping member 302, thereby realizing double locking of the built-in plate 105, so that the built-in plate 105 is stably set in the sole 101, and by arranging a reinforcement member 303 at the position of the built-in plate 105, the locking mechanism 300 and the positioning mechanism 200 are hidden, so that in daily use, the confidentiality of the internal structure and the firmness of the device are guaranteed.

[0039] It also includes an unlocking mechanism 400, which includes an annular member 401 disposed in the scaphoid surface 104, a movable member 402 is disposed in the positioning member 202, one end of the movable member 402 is disposed on the abutment member 203, and the other end of the movable member 402 contacts the annular member 401, a sliding member 403 is disposed in the scaphoid surface 104, and a moving member 404 is disposed at one end of the sliding member 403, and the moving member 404 is correspondingly abutted against the clamping member 302;

[0040] The present invention provides a new unlocking method for the locking form of the locking mechanism 300 and the positioning mechanism 200. A rotatable annular member 401 is provided on the scaphoid surface 104, and a variable diameter structure is provided inside the annular member 401, so that when the annular member 401 rotates, an extrusion force is formed on the movable member 402 and the movable member 404, so that the locking mechanism 300 and the positioning mechanism 200 are unlocked synchronously. In this way, when the positioner 502 is overhauled, the device can quickly replace the built-in plate 105.

[0041] A through hole 106 is provided in the heel portion 102, and a through slot 107 is provided in the forefoot portion 103. The through hole 106 and the through slot 107 have the same width and are in the same horizontal plane. Limiting rails 108 are correspondingly provided in the through hole 106 and the through slot 107. The limiting rails 108 are long strip structures. Limiting portions 109 are provided on both sides of the bottom end of the built-in plate 105. The limiting portions 109 are concave structures that cooperate with the limiting portions 109. The limiting portions 109 are correspondingly slidably connected in the limiting rails 108, so that the built-in plate 105 is more stable during installation.

[0042] Working principle: When installing the device, first align the limit part 109 and the limit rail 108, then insert the built-in plate 105 into the through hole 106 and the through groove 107, at this time, the limit part 109 is correspondingly slidably connected in the limit rail 108, so as to ensure the stability of the built-in plate 105 when inserted, and then the head of the built-in plate 105 is locked by the cooperation of the positioning member 202 and the insertion member 201, and the tail of the built-in plate 105 is fixed by the cooperation of the locking member 301 and the clamping member 302, so as to realize double locking of the built-in plate 105. When unlocking, it is only necessary to rotate the annular member 401, so that the annular member 401 forms an extrusion force on the movable member 402 and the movable member 404 when rotating, so that the locking mechanism 300 and the positioning mechanism 200 are unlocked synchronously, and by setting the reinforcement member 303, the present invention is not easy to be destroyed, which effectively improves the safety, durability and concealment.

[0043] Embodiment 2

[0044] The following technical features are added on the basis of the first embodiment: a safety mechanism 500 is also included, the safety mechanism 500 includes a mounting slot 501 provided in the built-in board 105, a locator 502 is provided in the mounting slot 501, the locator 502 is connected to a battery 503 via a cable, the locator 502 is connected to the electronic device terminal via a wireless communication module, and a storage module 504 is also provided in the mounting slot 501 for storing positioning information;

[0045] Through the positioning function of the locator 502, the user can grasp the real-time position of the elderly according to the terminal APP; from Example 1, it can be seen that the built-in plate 105 of the device is set in a hidden place of the sole 101 and is not easy to be found; and the reinforcement member 303 is set, so that the present invention is not easy to be destroyed, which effectively improves the safety, firmness and concealment;

[0046] By setting the locator 502 in the built-in board 105, the position of the locator 502 can be tracked and found in real time. When the device is used on the shoes of the elderly, since the shoes are not easy to be lost when worn on the feet, the user can find the specific position of the locator 502 according to the transmitted position information. The locator 502 is compatible with the system configurations of various user terminals. In the case where the existing mobile user terminals are highly popular, when the locator 502 is lost, it is very likely that there are multiple mobile user terminals within a certain range nearby. Therefore, when multiple mobile user terminals calibrate the position of the tracking locator 502 respectively, comprehensive information on the position of the tracking locator 502 is obtained. The positioning accuracy calibration rate is high, the user can narrow the search range, and improve the tracking efficiency. In this way, the locator 502 of the present invention has low energy consumption and long standby time. It can use the existing mobile communication network and technology to achieve tracking and positioning. It is easy to use and has low cost, which reduces people's usage costs and economic investment. It has a powerful anti-lost function and has the advantages of low power consumption and high precision.

[0047] Embodiment 3

[0048] The following technical features are added on the basis of the second embodiment: the inserting member 201 includes an inserting plate 201a integrally formed at one end of the built-in plate 105, a clamping joint 201b extends from the lower end of the inserting plate 201a to both sides, a compression space 201c is formed between the clamping joints 201b on both sides, and the bottom end of the clamping joint 201b is an extrusion surface 201d, and the locking member 301 includes a fixing plate 202a fixedly connected to the scaphoid surface 104, the fixing plate 202a is inwardly recessed to form a fixing groove 202b, and locking portions 202c are integrally formed on both sides of the inner wall of the fixing groove 202b, and the opposite sides of the locking portions 301b on both sides are pressure surfaces 202d, and the bottom of the locking portion 301b is a fixing surface 202e;

[0049] Depend on Figures 3 to 10 It can be seen that the plug plate 201a is a triangular structure, and the two groups of clamping joints 201b formed at the bottom of the plug plate 201a are made of deformable rubber material. When the clamping joints 201b on both sides are subjected to extrusion force, the clamping joints 201b are biased toward the compression space 201c. The fixed plate 202a is a concave structure, and the two side walls inside it are integrally formed with locking parts 202c, and the corresponding side thereof is a pressure surface 202d, and the pressure surface 202d is inclined, and the bottom is a fixed surface 202e, which is a parallel surface. When the plug plate 201a drives the clamping joints 201b on both sides to contact the pressure surface 202d, the clamping joints 201b on both sides are deflected toward the compression space 201c due to the extrusion of the pressure surface 202d. When it moves to the lower end of the locking part 202c, the clamping joint 201b is against the fixed surface 202e, thereby realizing the locking of the head of the built-in plate 105;

[0050] The resisting member 203 includes a compression spring 203a fixedly connected to both sides of the inner wall of the fixing groove 202b. The compression spring 203a is a carbon spring with high strength and is convenient for daily use. One end of the compression spring 203a away from the side wall of the fixing groove 202b is fixedly connected to a resisting block 203b. One side of the resisting block 203b is a resisting surface 203c. The resisting surface 203c contacts the clamping joint 201b. The bottom end of the resisting block 203b is fixedly connected to a wedge block 203d. The wedge block 203d is provided with a wedge surface 203e. The wedge block 203d is slidably arranged at the bottom end of the fixing groove 202b.

[0051] The present invention has compression springs 203a fixed on both sides of the inner wall of the fixing groove 202b, one end of the compression spring 203a is connected to a resistance block 203b, one side of the resistance block 203b is an inclined resistance surface 203c, and the resistance surface 203c is attached to the clamping joint 201b, and the bottom end of the resistance block 203b is fixedly connected to a wedge block 203d, and the wedge block 203d is slidably connected to the bottom end of the fixing groove 202b. An inclined wedge surface 203e is provided in the wedge block 203d, and the connection of the wedge surface 203e is a straight surface. When the wedge surface 203e is subjected to an extrusion force, the resistance blocks 203b on both sides are driven to extrude the clamping joint 201b, so that the clamping joint 201b is deformed;

[0052] Working principle: When installing the built-in board 105, it can be known from Example 1 that the built-in board 105 is first inserted into the through hole 106 and the through groove 107. At this time, the limiting portion 109 is correspondingly slidably connected in the limiting rail 108, thereby ensuring the stability of the built-in board 105 when inserted. At the same time, the two sets of card joints 201b on the plug plate 201a are in contact with the pressure surface 202d. At this time, the card joints 201b on both sides are deflected toward the compression space 201c due to the extrusion of the pressure surface 202d. When it moves to the lower end of the locking portion 202c, the card joints 201b are against the fixed surface 202e, thereby realizing the locking of the head of the built-in board 105, thereby realizing the preliminary positioning of the built-in board 105.

[0053] Embodiment 4

[0054] The following technical features are added on the basis of the third embodiment: the locking member 301 includes a locking strip 301a fixedly connected to both sides of the bottom end of the built-in plate 105, the limiting portion 109 is correspondingly fixedly connected to the side wall of the locking strip 301a, the bottom end of the locking strip 301a is integrally formed with a locking portion 301b, the lower end of the locking portion 301b is recessed to form a locking surface 301c, the locking surface 301c protrudes outwardly to form an integral clamping portion 301d, and the clamping member 302 includes a sliding connection to the inner wall of the through groove 107 The clamping plate 302a is provided with a clamping groove 302b in the clamping plate 302a. The clamping groove 302b is composed of a pressing surface 302c, a clamping surface 302d and a translation surface 302e. The clamping portion 301d is correspondingly pressed against the clamping surface 302d. Two groups of auxiliary springs 302f are fixedly connected to the side wall of the clamping plate 302a. The auxiliary springs 302f are carbon springs with high strength and are convenient for daily use. The two groups of auxiliary springs 302f are correspondingly fixedly connected to the side walls of the through slot 107.

[0055] Depend on Figures 3 to 10 As can be seen, a long strip-shaped locking strip 301a is fixed on both sides of the bottom end of the built-in plate 105, and a locking portion 301b is integrally formed at the bottom end of the locking strip 301a, and a locking surface 301c and a clamping portion 301d are formed in the locking portion 301b. When the locking portion 301b is inserted following the built-in plate 105, its clamping portion 301d contacts the pressing surface 302c, so that the clamping plate 302a moves to both sides. At this time, the auxiliary spring 302f is deformed. When the clamping portion 301d moves to the tail end of the pressing surface 302c, the clamping portion 301d slides into the translation surface 302e accordingly. Under the restoring force of the auxiliary spring 302f, the clamping plate 302a is driven to retract. At this time, the clamping portion 301d is correspondingly pressed against the clamping surface 302d, thereby completing the locking of the built-in plate 105.

[0056] The reinforcing member 303 includes a reinforcing strip 1 303a and a reinforcing strip 2 303b fixedly connected to the built-in plate 105 and the locking strip 301a, the reinforcing strip 1 303a and the reinforcing strip 2 303b are symmetrically arranged up and down, a reinforcing rod 303c is pasted between the reinforcing strip 1 303a and the reinforcing strip 2 303b, and there are multiple groups of reinforcing rods 303c, which give corresponding supporting forces to the reinforcing strip 1 303a and the reinforcing strip 2 303b, the insert 201 is arranged between the reinforcing strip 1 303a and the reinforcing strip 2 303b, and a reinforcing plate 303d can be placed in the through hole 106 and the through groove 107, and the reinforcing plate 303d is made of elastic material, and is inserted into the through hole 106 and the through groove 107 by bending and deformation, and the reinforcing plate 303d protects the positioning mechanism 200 and the locking mechanism 300;

[0057] Depend on Figures 1 to 10It can be known that the built-in plate 105 and the locking strip 301a are respectively fixed with the reinforcement strip 1 303a and the reinforcement strip 2 303b, and the reinforcement strip 1 303a and the reinforcement strip 2 303b are connected by the reinforcement rod 303c. The reinforcement strip 1 303a and the reinforcement strip 2 303b are made of elastic and deformable materials, and the reinforcement rod 303c is made of rigid material. A reinforcement plate 303d is placed in the through hole 106 and the through groove 107. The reinforcement plate 303d is made of a bendable and deformable material. It is bent on the scaphoid surface 104 and inserted into the through hole 106 and the through groove 107, thereby realizing the protection of the positioning mechanism 200 and the locking mechanism 300, and improving the concealment and safety of the internal structure.

[0058] Working principle: It can be seen from Example 3 that when the locking part 301b is inserted along with the built-in plate 105, its clamping part 301d contacts the pressing surface 302c, so that the clamping plate 302a moves to both sides. At this time, the auxiliary spring 302f is deformed. When the clamping part 301d moves to the tail end of the pressing surface 302c, the clamping part 301d slides into the translation surface 302e accordingly. Under the restoring force of the auxiliary spring 302f, the clamping plate 302a is driven to retract. At this time, the clamping part 301d is correspondingly pressed against the clamping surface 302d, completing the locking of the tail end of the built-in plate 105. In this way, the device is fixed by double locking the head and tail of the built-in plate 105, which is not only convenient to operate but also ensures the stability of the device.

[0059] Embodiment 5

[0060] The following technical features are added on the basis of the fourth embodiment:

[0061] The annular member 401 includes a rotating shaft 401a rotatably connected to the scaphoid surface 104, a circular plate 401b is fixedly connected to the outer wall of the rotating shaft 401a, and a reducing portion 1 401c and a reducing portion 2 401d are integrally formed on the circular plate 401b. A torsion spring 401e is sleeved on the outer wall of the rotating shaft 401a. The torsion spring 401e is a carbon spring with high strength and is convenient for daily use. One end of the torsion spring 401e is fixedly connected to the circular plate 401b, and the other end of the torsion spring 401e is fixedly connected to the scaphoid surface 104. An arc hole 401f is provided on the outer wall of the circular plate 401b, and a positioning rod 401g is provided in the arc hole 401f, and one end of the positioning rod 401g is arranged on the scaphoid surface 104;

[0062] Depend on Figures 1 to 10It can be seen that the present invention further defines the unlocking structure, wherein a rotating shaft 401a is rotated in the scaphoid surface 104 through a torsion spring 401e, a circular plate 401b is fixedly connected to the rotating shaft 401a, and a reducing portion 1 401c and a reducing portion 2 401d are formed on the circular plate 401b. Since the diameters of the reducing portion 1 401c and the reducing portion 2 401d are different, when the circular plate 401b rotates, an extrusion force is formed on the object around the circular plate 401b, and an arc hole 401f is provided on the outer wall of the circular plate 401b, and a positioning rod 401g is provided in the arc hole 401f, so as to limit the rotation angle of the circular plate 401b;

[0063] The movable member 402 includes two groups of movable rods 402a movably connected in the fixed plate 202a, and the bottom joint of the two groups of movable rods 402a is fixedly connected with a movable plate 402b, and the two groups of movable rods 402a are correspondingly pressed against the wedge surface 203e, and the movable plate 402b is correspondingly matched with the diameter reducing portion 1 401c, and the sliding member 403 includes a slide rail 403a fixedly connected in the through groove 107, and a slider 403b is slidably connected in the slide rail 403a, and a slide rod 403c is fixedly connected at one end of the slider 403b, and a compression spring 403d is sleeved on the outer wall of the slide rod 403c, and an arc block 403e is fixedly connected at one end of the slide rod 403c, and the diameter reducing portion The two 401ds are matched with the arc-shaped blocks 403e, and the moving member 404 includes a triangular block 404a fixedly connected to one end of the slider 403b, and the two sides of the triangular block 404a are integrally formed with oblique strips 404b, and the through slot 107 is slidably connected with two groups of trapezoidal blocks 404c in the horizontal direction, so the two groups of trapezoidal blocks 404c can only move in the horizontal direction, and the corresponding side of the trapezoidal block 404c is provided with an oblique groove 404d, and the oblique groove 404d is correspondingly slidably connected in the oblique groove 404d, and the corresponding ends of the trapezoidal blocks 404c on both sides are fixedly connected with a contact rod 404e, and the contact rod 404e is correspondingly abutted against the side wall of the clamping plate 302a;

[0064] Depend on Figures 1 to 10 It can be seen that by further refining the internal structure of the fixed plate 202a, two groups of movable rods 402a are slidably connected inside the fixed plate 202a. The movable rod 402a can be divided into two parts, one part is located inside the fixed plate 202a, and the other part is located outside the fixed rod. The diameter of the rod body of the movable rod 402a located inside the fixed plate 202a is larger than the diameter of the rod body of the movable rod 402a located outside. This arrangement makes it impossible for the movable rod 402a to move outward, but only to move inward. At the same time, a movable plate 402b is fixed at the joint of the bottom ends of the two groups of movable rods 402a, so as to limit the moving distance of the movable rod 402a, and the heads of the two groups of movable rods 402a are correspondingly pressed against the wedge surface 203e.

[0065] A slide bar 403c is fixed on the upper end of the slider 403b, and the slide bar 403c is connected to the surface of the slide rail 403a through a compression spring 403d. An arc block 403e is fixedly connected to the upper end of the slide bar 403c. By setting an arc-shaped contact area, it is ensured that the second diameter reducing part 401d can stably cooperate with the arc block 403e when rotating. When the second diameter reducing part 401d gives an extrusion force to the arc block 403e, the slider 403b on the slide bar 403c moves in the slide rail 403a, thereby driving the triangular block 404a at the bottom end of the slider 403b to move, and the inclined bars 404b on both sides of the triangular block 404a move in the inclined grooves 404d. When the triangular block 404a moves downward, it drives the trapezoidal blocks 404c on both sides to move in reverse.

[0066] Working principle: when the positioner 502 in the built-in plate 105 needs to be inspected, the reinforcing plate 303d only needs to be bent and taken out, and then the rotating shaft 401a is rotated. When the rotating shaft 401a moves, the circular plate 401b is synchronously driven to rotate. At this time, the reducing portion 1 401c and the reducing portion 2 401d on the circular plate 401b rotate synchronously. Since the movable plate 402b is matched with the reducing portion 1 401c correspondingly, and the reducing portion 2 401d is matched with the arc block 403e correspondingly, when the reducing portion 1 401c contacts the movable plate 402b, the two groups of movable rods 402a on the movable plate 402b are driven to move upward. At this time, the upper end of the movable rod 402a contacts the wedge surface 203e, thereby driving the two groups of wedge surfaces 203e to move toward each other, so that the clamping joint 201b and the fixed surface 202e are no longer in conflict, thereby achieving To unlock the head of the built-in plate 105, when the second reducing portion 401d conflicts with the arc block 403e, the arc block 403e squeezes the slider 403b on the slide rod 403c and moves in the slide rail 403a, thereby driving the triangular block 404a at the bottom of the slider 403b to move, and the inclined bars 404b on both sides of the triangular block 404a move in the inclined groove 404d. When the triangular block 404a moves downward, it drives the trapezoidal blocks 404c on both sides to move backwards. When the trapezoidal block 404c moves, it drives the resistance rods 404e on both sides to move synchronously. The resistance rods 404e correspondingly contact the side walls of the clamping plate 302a. At this time, the clamping portion 301d is separated from the clamping surface 302d, thereby realizing the unlocking of the tail of the built-in plate 105. In summary, the two mechanisms are unlocked by rotating the circular plate 401b, which makes the operation more convenient.

[0067] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
