Description

    The present invention allows a disabled person (13) to be transported lightly and easily by an elderly person or a woman alone, and in the middle of the transport, the stretcher (1) can be temporarily rested or waited in the state without being lowered to the soil (10) or the floor. be able to. In addition, it is a self-supporting stretcher with wheels that can be used as a substitute for a pedestal or chaise longue without transporting.

    In conventional stretcher transport, the victim is lifted by a plurality of two to four people including the stretcher. When the weight of the victim becomes 40 kg to 80 kg, the transporter includes 20 to 40 kg including the stretcher. It is not easy even for firefighters and emergency personnel who are trained as a very tough occupation because they will lift and carry the load. Moreover, it was almost impossible for ordinary citizens, and even when the stretcher was on the site, it was often not used up.

    In this regard, although it is a structure that can be transported by one person in Patent Document 1, the number of parts is large and the parts are divided into several parts before assembly, and a tool is used during the assembly. For this reason, a certain level of knowledge and experience is required during assembly and disassembly. Even during storage and storage, management of parts is extremely important. The present invention attaches great importance to this point, and the assembly and storage procedures are extremely small and can be completed in 1.2 minutes. Next, all parts from the assembly, storage, and storage are integrated and never lost. No tools are required until assembly, storage, and storage. Therefore, even an inexperienced person who has never seen it for the first time can easily imagine the storage procedure by assembling the stand and wheels. Patent Document 2 is intended to be transported by one person as in Patent Document 1, and is made portable by using a support mechanism and a wheel mechanism as auxiliary tools by being detachable from an existing stretcher. This method is based on the assumption that the victim can be placed on the stretcher between the soil, and then the strut mechanism and the wheel mechanism are built into the stretcher, and then the stretcher is raised, but the work procedure is complicated due to the complexity of the mechanism. The training is extremely frequent and requires regular training to the extent that knowledge and experience and work procedures are not forgotten. In addition, the stretcher itself has a large amount of deflection and twist during transportation, and the support bracket that sandwiches the strut and the stretcher bar of the wheel part loosens during transportation and may come off.If the wheel side comes off, the victim falls from the stretcher. The danger to do is considered enough. The present invention attaches great importance to this point, and the stand and wheel mechanism are structurally integrated with the stretcher by screws or welding, and there is no detachment, and the stand and the bracket receiving the wheel have a certain degree of flexibility for deflection and twisting. Have fun. Therefore, there is no anxiety for the carrier who knows that the stand and the wheel part will not come off. The mechanism of this patent document 2 is a structure that does not use a tool at the time of assembly and disassembly, but the mechanism of the stretcher, the support column, and the wheel part can be attached and detached, so that a certain size can be reduced, but the mechanism is complicated and assembly and disassembly. The storage procedure is complicated and the number of parts is different, which makes it difficult to manage storage without loss. The present invention can be assembled without removing one screw until the basic design is assembled and stored. Basically, it is an extremely simple mechanism that only requires a stand and wheels to be fixed with a knob after turning 90 °, so it is a self-supporting stretcher with wheels that can be reassured not only by the transporter but also by the manager.

    When transporting on a stretcher in an emergency, it was difficult for four people to transport it lightly and easily, and while maintaining the transport state during transport, it was impossible to take a short pause or wait, and it was not possible to cope with it except to lower it to the dirt or the floor. Conventionally, there was a stretcher for the purpose of reducing the burden on the transporter, but it was structurally complicated to mount a stand and wheels on the stretcher, and the assembly of the procedure and mechanism was confused in an emergency. For that purpose, regular training and skill until learning the procedure with the body was required. In addition, the wearing part may be loosened due to vibration or stretching and twisting of the stretcher during transportation, giving safety concerns to the victim and the carrier.

Means to solve the problem

(A) The stretcher (1) and the stand (3), the wheel (4) and the bracket (5) attached thereto are fixed to the stretcher bar (2), and the stand (3) and the wheel ( 4) A mechanism for raising and fixing in a vertical position.
(B) The stand (3) and the wheel (4) added to the stretcher having a two-fold or four-fold structure are folded in the retracted position or fixed in the vertical position. A structure that can be folded in the width direction.

The invention's effect

(A) The patient (13) can be transported as shown in FIG. 14 by one carrier (14).
(B) The load of the carrier (14) can be reduced to ¼ to ¼ of the conventional load when the wheel (4) receives most of the loads of the victim (13) and the stretcher (1).
(C) While the patient (13) is being transported, the stand (3) is lowered to the soil (10) while maintaining the transported state, and the stretcher is placed in parallel at the height of the knee so that a short pause or standby can be performed.

    (I) The wheel (4) is larger than the stretcher used in many ambulances and hospitals, and its diameter is very large, around 40 cm, and the rubber part is thick and there is a cushion. Without falling down, shock such as vibration applied to the patient (13) can be minimized and stably conveyed.

(A) Assembly can be completed in a short time of about 1 to 2 minutes by raising the stand (3) and wheels (4) very easily from the storage state to preparation for use.
(B) After retracting the stand (3) and the wheel (4), the storage space can be extremely reduced by leaning the stretcher (1) against the wall as shown in FIG. In addition, the storage space can be reduced to 1/8 or less of the assembled state by reducing the width, height, and length by folding the stretcher in two and in four. is there. It can be easily stored and transported even with a storage box with a wheel or a wooden box.
(C) Since the structure is simple and no special mechanism or parts are used, the cost can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
(A) A bracket (5) incorporating a stand (3) and wheels (4) is attached to the stretcher (1) at a position about 1/4 from both ends in the longitudinal direction of the stretcher bar (2) by screws or welding. Fix it.
(B) The bracket (5) is structured such that the stand (3) and the wheel (4) can be turned and retracted from the vertical position of the stretcher toward the center.
(C) To turn the stand (3) and the wheel (4) from the vertical position to the retracted position, loosen the stay fixing knob (6) and turn the stand (3) and the wheel (4) to move to the retracted position that is the end. Tighten the stay fixing knob (6) with It also has the function to fix the movement to the vertical position side in the same way in the opposite direction.

    An embodiment will be described below with reference to the accompanying drawings. 1, 7, 8, 9, 11, 13, 14, and 15, the stretcher (1) is a commercially available two-fold or four-fold stretcher, and the carrier (14) The stretcher bar (2) is the part gripped when transporting. In the present invention, the following part is newly added to the stretcher bar (2). As shown in each figure, the bracket (6) with a folding mechanism has a stand (3) for smooth movement of the stand (3) to the vertical position and standby position, and to eliminate the wobbling of the stand (3) at both positions. There is a stay fixing knob (6) to fix firmly. Of course, the stand (3) also has the stay (7) and the stay fixing knob (6) in the vertical position for allowing the stretcher (1) to stand on the ground (10) and the floor (11) as shown in FIG. 3) It moves in the stay moving groove (17) of the bracket (5) in synchronization with the 90 ° turn. The stand (3) is firmly fixed by tightening the stay fixing knob (6) that was loosened while turning the stay (7) firmly at the fixed position of the stand-alone vertical position and the folded standby position. Longitudinal wobble can be prevented. The state of FIG. 1 can be maintained by fixing the wheel (4) so that it does not wobble in the vertical position by the same method. To prevent wobbling in the width direction, the stretcher bi-fold pipe (8) is built in two places on the stand (3) side and the wheel (4) side, and the stretcher (1) is widened and fixed at its width. It is solved by that.

    Examples will be described with reference to FIGS. 2, 9, 10, and 15. The commercially available stretcher (1) has a merit that it can be downsized by changing the width of the stretcher width (16) from the stretcher width expansion direction (16) as shown in FIG. 2 when viewed from the top, and FIG. 10 when viewed from the side. By adding the bracket (5), the stand (3), the wheel (4), etc. which are the legs of the present invention to the stretcher (1) of this structure, as shown in FIG. As shown in FIG. 4, the stand (3) and the wheel (4) are folded as compared to the self-supporting height (26) as shown in FIG. The floor area when leaned up is more efficient as a storage place because it has the advantage of being able to further reduce the floor area.

    Examples will be described with reference to FIGS. 1, 12, 13, and 14. As shown in FIG. 1 and FIG. 14, the stand (3) side of the self-supporting stretcher with wheels of the present invention is placed on the stretcher (3) as the head of the patient (13). The carrier (14) is positioned on the same stand (3) side, holds the stretcher bar (2), and moves forward as shown in FIG. At this time, the stand (3) is transported away from the earth (10) by approximately 10 Cm. When traveling forward, the wheel diameter is as large as around 40 Cm even on some pebbles, gravel roads, and muddy roads, and it can be easily transported and moved by using cushioned no-punctured wheels (4) and absorbs vibrations and shocks. There is an advantage that the patient (13) is not burdened.

    3, 5, 6, 16, and 17, in the case of a four-fold stretcher, a normal stretcher has a length of about 2 m in the longitudinal direction, but it is too long and inconvenient for storage and movement. However, it can be solved to some extent by folding it in four. Therefore, by adding a bracket (5), a stand (3), a wheel (4), etc., which are the legs of the present invention even in a four-fold stretcher, as shown in FIGS. 3, 5, 6, and 16, During storage, the stretcher folds the stand (3), wheels (4) and stretcher bar (2) in each direction 18, 19, and 20 as shown in FIG. It is small enough to be about 1/8, making it ideal for storage, storage and transportation. In addition, it is folded back from the center of the stretcher at the time of four-folding and assembling, but the hinge (15) is fixed to the folding connecting portion at this time and the stretcher four-fold fixing pin (16) for the purpose of fixing it firmly at the time of assembly. Etc. are used. FIG. 17 shows the assembled state.
