Various patents and designs are known in the state of the art in the safety devices of the protective tape.

Therefore, in 2012, UBIOTEX ESPAÑA, SL applied for utility model patent No. 201230982 (ES1077804) "SAFETY CATCH FOR PATIENT SUPPORT BELTS WITH COIN-OPERATED OPENING for supporting patient's seat belts" a safety clasp with a coin-operated opening for a seat belt for supporting a patient, characterized in that it comprises a cylindrical rod having a circular base, wherein the wheelbase has a longitudinal groove and another adjacent to its flat end Circular peripheral groove and in the shape of the cylinder ring The hub of the side groove and the central circular hole for connecting the cylindrical rod. There is a V-shaped spring or hook in the ring, which is held by two bolts, one of which is tied to the apex of V and the other of which is surrounded by one of its ends, but the other end is unfixed. .

In 1996, a so-called button catches, including a main body and a cover body, and employing an octagonal cylinder having a rounded edge, are known as the Spanish Industrial Design Patent No. 136,873 filed by the same applicant company. With a lower height relative to its maximum height range, one of the substrates has a minute circular groove covering almost the entire surface and a circular hole having a small diameter on the other substrate, being centered with respect to the octagonal surface. The cover is pushed out of the body using a magnetic control key.

This button clasp has been applied to the utility model patent No. 0234178 of the SEGUFIX-SYSTEM BANDAGEN-UND FIXIERGURTE GMBH & CO company in 1978. "DEVICE FOR SUPPORTING A HUMAN BODY IN A PREDETERMINED POSITION ON A BED)" is described but not claimed, and is currently known to the public, wherein the button clasp is shown at symbol 13 and is described as "clips".

As described in the industrial design patent mentioned above, the button retaining ring generally comprises a lower base integral with the rod, the rod being inserted into the top base and being pushed out by a key comprising a magnet.

In these descriptions, we are known from the European Patent No. EP 2 463 459, which is hereby incorporated by reference in its entirety in the entire disclosure of the disclosure of the entire disclosure of In a rotary button clasp surrounding the axis of rotation; and at least one interlocking element coupled to at least the first magnet such that the interlocking element is movable from the locked position by rotating at least one first magnet about the periphery of the rotating shaft To an open position; characterized in that the button clasp has a first guiding member such that when a magnetic key having a second guiding member adapted to the bottom buckle approaches the button clasp to a final position along the axis of rotation, The magnetic key and the button retaining ring are guided to a predetermined rotational position with respect to the rotating shaft and the guiding member.

Another patent No. EP1355550, which is one of the applicants, is directed to a button retaining ring on which a magnet rotates. The modality is received around a rotating shaft that is coupled to some interlocking elements via a rotating disc having a drag stop point. Each interlocking element is pretensioned via a spring in the interlocking position. The interlocking element is moved to the open position by rotating a magnet around the axis of rotation. In order to open the known button clasp, a magnetic key is disposed in the button clasp, the magnetic key comprising various magnets capable of producing a magnetic field having a shape that changes around a longitudinal axis of the magnetic key. Due to the rotation of the magnetic key, a torque can be applied to the magnet of the button snap to rotate the magnetic key and move the interlocking element to the open position. This type of magnetic lock provides considerable safety in preventing unauthorized opening, so the necessary torque to open can't be produced only with normal magnets, and because it is usually impossible to hit the button clasp by hitting or tapping. magnet. However, since a suitable magnetic key should also be used, it is difficult to open in the case of the above-mentioned relatively simple magnetic lock, so the magnetic key must be selectively rotated for the button retaining ring. In order to be able to carry out this movement with one hand, the known magnetic lock arrangement prevents the rotation of the button clasp in the bar at the slot and prevents the safety element from rotating about the slot of the seat belt, which requires a relatively complicated The structure is rotated.

Finally, it is worth mentioning that the patent No. 5600977 "MAGNETIC LOCKING DEVICE", which is filed by PINEL MEDICAL INC, in 1995, relates to a locking device having a non-magnetic plug and a button, the non-magnetic plug having a base and a slave The rod protrudes in a vertical direction, and the rod extends to an unfixed end and has a toothed portion near the unfixed end.

The button is a closed, non-magnetic unit having a hole on the lower surface adapted to receive the unfixed end of the rod, and which also includes a plurality of locking plates, each supporting the exterior via a compressible support material and adapted to maintain The peg is within the toothed portion of the locked position within the button and rotates upwardly and pushes the peg in response to the magnetic force directed at the upper surface of the button. This magnetic force can be supplied via a magnet arranged in a key adapted to fit on the button.

The present invention is an improvement in the slot of a security device for a medical belt, which is also known as a button snap ring.

The closest document is U.S. Patent No. 5,600,977. This document addresses the problem of the risk of interference with magnets of other devices, thus configuring a key with some magnets that, when coupled with the button to reduce the distance between the key magnet and the button, can reduce the actual The magnet is magnetic and prevents the risk of interference.

Thus, the patent uses a half-moon strip in which it is removed and moved by the action of the key magnet, thereby causing the rod to exit the head of the button. In order to facilitate the return of the strips to their original positions, a compressible material, preferably foam, is used, the foam being placed under the strips, such that when the rods are pushed out, the strips are stripped The foam is compressed and, when suctioned through the magnet end, the foam will not compress, driving the strip back to their operational position.

And this recovery component is the crux of the problem, the most important thing is that the foam can not be wet or wet, because the foam will be damaged to the extent that it can not be used.

At the same time, if the foam is full of liquid, it will not work in the same way, the foam will not be compressed, so the device will not be used when the patient is bathing, and the patient will not be able to use any body fluids. Device.

Another problem is the problem of locating the strip, due to the action of the magnet and the foam, because the strip will randomly push the strip when it is unable to compress, causing them to move to a position where it is not working properly.

Based on the above, the inventor of the present invention proposed a new invention that can solve the closest document.

Therefore, first, the closest patented foam recovery member is removed. This means that the device of the present invention can be wetted, it can be immersed in water with the patient, and the patient can bathe with detergent or the like because there is no problem that the foam is destroyed.

At the same time, the strips never lose their position, they are always placed in place because the retaining members act on the strips and prevent them from moving.

Another advantage of the present invention is that in the locked position the strip is placed in a stationary position which is the position of the strip in a normal state and automatically enters a rest position when the key is removed from the top substrate.

At the same time, it is ensured that the strips return to the original rest position, thereby reducing the likelihood of malfunction of the device.

One aspect of the present invention is a belt safety device comprising: at least two substrates, one being a bottom substrate and the other being a detachable top substrate having a interior of the top substrate a rod; a rod body integral with the bottom substrate and coupled to the top substrate; a key having a first magnetic member and disposed on the top substrate, and wherein the belt is secured The device includes: a groove surrounding the rod, wherein the rod is disposed in the housing in the top substrate when the rod is attached to the top substrate; some locking members are in the shell a strip having two opposing metals, the strips being adapted to fit within the recessed position, the strap security device comprising: a second magnetic member within the housing Disposed under the strips and having a smaller suction force than the first magnetic member of the key; and some retaining members holding the strips and disposed over the strips such that the retaining members are Point P is in contact with the strips, wherein the strips are in the locked position, the rods within the housing are prevented from being pushed out due to the action of the second magnetic member being adapted to fit within the recess, and In the locked position, the first magnetic structure The pieces resist the suction of the second magnetic members on the strips, attracting the strips and twisting at point P, ejecting the strips from the grooves and also ejecting the rods from the top substrate.

BRIEF DESCRIPTION OF THE DRAWINGS For the convenience of the description of the present invention, in conjunction with the description of the six figures of the embodiments of the present invention, the drawings are intended to be illustrative of the scope of the invention. The first figure is a front view of the aspect of the invention with a key. The second figure is a cross-sectional view of the unlocking configuration of the first figure; the third figure is a plan view of the top substrate of the first figure not covering the cover in the unlocking configuration; the fourth figure is the first figure is locked A cross-sectional view of the configuration in which the key is not included; the fifth view is a plan view of the top substrate covering the top of the cover in the locked configuration; and the sixth view is an embodiment of the present invention having a grooved rod Bottom perspective view.

In view of this, the first figure shows the bottom substrate 1, the top substrate 2 and the key 31 having the rod-like body 3.

The second figure illustrates a bottom substrate 1 having a rod 3 and a groove 5, a top substrate 2 having a housing 30, some holding members 34, some perforations 36, and some first magnetic members A key 31 of 32 is provided with a plurality of strips 8 and 9 including a notch 39 and a projection 35 in the casing 30.

The third figure shows the top substrate 2, the rod 3, the housing 30, the strips 8 and 9 with the notches 39, some of the second magnetic members 33 and some of the separating members 40.

The fourth figure illustrates a bottom substrate 1 having a rod 3 and a groove 5, a top substrate 2 having a casing 30, a holding member 34, and a perforation 36 in which a recess 39 and a projection 35 are disposed. Strips 8 and 9.

The fifth figure shows the top substrate 2, the rod-like body 3, the casing 30, the strips 8 and 9 having the notches 39, the second magnetic member 33, and the separating member 40.

Finally, the sixth figure shows the bottom substrate 1, the rod 3 having the groove portion 37, and the top substrate 2 having the opening 38.

For the sake of clarity, the top substrate 2 has been given a symbol to indicate that it forms a unit. In terms of construction, it consists of two structures (the top shell and the bottom shell bottom), which can be seen in some drawings and defined as the shell 30 when the two structures are joined. Since this is known, it has been referred to as the top substrate 2 as a whole for ease of reading.

Thus, in a particular embodiment, the apparatus of the present invention functions in the following manner.

First, in the locked position (fourth and fifth figures), the strips 8 and 9 are fitted in the recess 5 of the rod 3. In this manner, if it is attempted to separate the top substrate 2 from the bottom substrate 1, it is impossible because the strips 8 and 9 that lock the rod 3 cannot push out the rod 3, that is, the strips 8 and 9. It is also locked via the second magnetic member 33 (for example, a magnet).

The locking members are two opposing metal strips (8 and 9) located inside the housing 30.

The device also has a second magnetic member 33 inside the housing 30, the second magnetic member 33 being disposed below the strips (8 and 9) and having a smaller suction force than the first magnetic member 32 of the key 31.

The characteristics of the first magnetic member 32 are very important so that the first magnetic member 32 can resist the suction of the second magnetic member 33 toward the strips 8 and 9.

The holding members 34 (second and fourth figures) for holding the strips 8 and 9 are disposed on the strips Above the strips 8 and 9, and in contact with the strips 8 and 9 at point P.

Therefore, as described above, in the locked position, the strips 8 and 9 prevent the rod-like body 3 from being pushed out from the inside of the casing 30 due to the action of the second magnetic member 33 being adapted to fit inside the recess 5.

On the other hand, in the unlocked position, the first magnetic member 32 is disposed in the key 31 to resist the suction of the second magnetic member 33 on the strips 8 and 9, and the strips 8 and 9 are attracted toward the first magnetic member 32. Torsion at point P, the strips 8 and 9 are pushed out from the groove 5 and the rod 3 is also pushed out from the top substrate 2.

As shown in the third figure, at point P, the retaining member 34 causes portions of the strips 8 and 9 to function, and portions of the strips 8 and 9 in the recess 5 rise, but on the other hand, the retaining member 34 prevents The entire strips 8 and 9 are attracted, and the strips 8 and 9 are twisted by the influence at point P.

In order to facilitate the understanding of the actions described in the preceding paragraph, the strips 8 and 9 may optionally comprise projections 35 on which the strips 8 and 9 are twisted in a locking-unlocking action, with respect to the absence of protrusions Strips 8 and 9, which facilitate twisting action.

Further, it is also optional that the strips 8 and 9 include respective recesses 39 on their upper surface for receiving a portion of the retaining member 34, the recess 39 containing the P-point located therein. In this manner, in addition to the twisting action, the strips 8 and 9 are more reliably held in their position.

The inventors of the present invention have confirmed that the best results are obtained if the second magnetic member 33 is disposed between the strips 8 and 9.

The retaining member 34 can be made of the same material as that used for the top substrate 2.

The top substrate 2 can be made of a heat resistant material. The heat resistant material has a wide range, and as a non-limiting example, a certain metal, a hardened plastic, or the like can be used.

As described above, the present invention has overcome one of the problems of the prior art because the foam does not exist and there is no possibility that water will enter the casing 30.

That is, this means that the present invention has the advantage of allowing the patient to be wetted in water, or even allowing the device to be cleaned with a cleaning product if the cleaning product does not affect the magnetic properties of the device of the present invention. It means that the device will not be damaged and is very durable with a longer life.

The present invention also contemplates that it can be selectively fabricated in the top substrate 2 for use in connection. A perforation 36 is formed outside the housing 30. First, as shown in the second and fourth figures, the perforations 36 are disposed at the bottom of the top substrate 2 to facilitate sufficient drainage of the outer casing 30.

In this manner, the devices are suitable for use even in water because the magnetic or magnetic members are unaffected and any liquid can be expelled via the perforations 36.

To further enhance reliability, the inventors have envisioned that the selectable rod 3 includes at least one groove portion 37 that is at least partially inserted into the top substrate 2. The top substrate 2 includes an opening 38 having an outer edge that is part of the groove portion 37 of the rod 3. This way it is possible to avoid the rotation of the rod 3 on the top substrate 2.

The strips 8 and 9 have a meniscus structure, and in the present embodiment, the shape of the top substrate 2 is cylindrical.

It has been contemplated that the separating member 40 is disposed between the strips 8 and 9 to increase the reliability with which the strips 8 and 9 will return to the correct locking position. In other words, the centers of the strips 8 and 9 are improved during operation of the locked and unlocked positions of the rod 3 so that the device has the advantage that the strips 8 and 9 will return to the proper position when returned to the locked position. .

In this manner, if it is necessary to separate the device, that is, to separate the bottom substrate 1 from the top substrate 2, it is carried out as follows.

The key 31 is disposed above the top substrate 2 so that the first magnetic members 32, such as magnets, are sufficiently close together that their attractive force can move the strips 8 and 9 of the metal.

In this manner, since the first magnetic member 32 has a stronger suction force than the second magnetic member 33, the first magnetic member 32 attracts the strips 8 and 9 of the metal as described above, and the strips 8 and 9 are inclined from the concave The slot 5 is pushed out.

As explained in more detail above, the strips 8 and 9 are only tilted, and due to the effect of the retaining members 34 on the strips 8 and 9, the strips 8 and 9 are retained at point P and the strips 8 and 9 are prevented from moving.

Once the strips 8 and 9 are pushed out of the recess 5, the rod 3 is unfixed and will be removed from the top base 2.

The key 31 is then removed from the top substrate 2 and the strips 8 and 9 will return to their rest position.

If you need to place a device on the patient to fix the hospital seat belt, The body 3 is inserted through the opening 38 (the groove is shown in the sixth figure or without the groove) until it is pushed to the inside against the resistance of the strips 8 and 9.

The strips 8 and 9 are then repositioned within the recess 5 via a portion thereof to a rest position, thereby locking the rod 3 within the top base housing 2 via the strips 8 and 9.

In this manner, if the patient wants to rotate the rod 3 or unravel the patient himself, the device can be sufficiently locked to prevent the rotation of the rod 3.

The present invention describes a novel belt safety device. The examples referred to herein are not intended to limit the invention, and thus, the invention may have various applications and modifications within the scope of the following claims.
