Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a care trolley, and more particularly, to a care trolley that can be conveniently and safely used by people with impaired free actions such as illness / medicine patients, bedridden elderly, and physically handicapped persons.

[0002]

[Prior art and problems]

 Nursing care trolleys consist of a pedestal on which a patient, etc., should be placed on a base that has casters for traveling on the bottom, and allow freedom of physical exercise such as illnesses and medical patients, bedridden elderly, and physically handicapped persons. It is widely used as a means of transporting people who have been robbed. Conventionally, a four-point support care trolley that supports the pedestal stably by erected support means at the four corners of the base has been commonly used, but nowadays it is planted at two corners at one end in the longitudinal direction of the base. A structure with a two-point support in which the pedestal is fixedly supported by the upright supporting means and the base and pedestal on the other end side is open is provided, and the application is expanding. This is because when using a care trolley that supports two points, the treatment table, work table, bed, etc. can be sandwiched in the open space formed between the base and the gantry, and it can be used exclusively when stopped. In addition to reducing the area, it is convenient for medical / nursing work while being placed on the gantry and for moving the pedestrian between the gantry and other positions (for example, a treatment table / workbench / bed). This is because there are many cases where An example of this is bathing care at a medical treatment / nursing facility. Immediately, in recent medical and nursing care facilities, a nursing bath device (a water tank is installed in the middle part of the base to separate and form empty spaces above and below the upper empty space to reduce the burden and danger of bathing care). The shower room above the water receiving tank accommodates and supports bathers for bathing in the shower.The applicant also submitted a utility model registration request for this and the simultaneous submission: Improvement by the reference number U04-077. Has been applied for). With this care bathing device, a two-point support care trolley allows bathing care while the bather is placed on the cradle with a water receiving tank sandwiched in the open space between the base and cradle. However, in a care trolley with four-point support, the bather must be moved from the gantry to the shower room and supported above the water tank, and the burden of care cannot be reduced.

As described above, the two-point support nursing care trolley has been recognized to have a great advantage, but on the other hand, it is difficult to provide the pedestal with an elevating function. This is a four-point support nursing care trolley. It is a big problem when compared to the trolley. That is, various patient placement means such as a treatment table, a work table, and a bed have a surface height according to the purpose of the work, and if the platform of the care trolley cannot be adjusted up and down according to each height. This is because the transportation, treatment, and care services must be significantly impeded. In this respect, the four-point-supporting care trolley originally has a stable structure in which the pedestal is supported by the support means that are planted in the four corners, and any lifting mechanism is attached to these support means. Only by doing so, it is possible to easily ensure a smooth and quiet lifting function. On the other hand, since the two-point support care trolley only has to provide the supporting means on one end side in the longitudinal direction of the base / frame, it is possible to obtain a smooth and quiet lift even if a normal lifting mechanism is optionally attached. However, it could not be denied that there is a risk that unpleasant vibrations and intermittent ascending / descending may cause anxiety to the placing person and further cause instability of the placing itself.

[0004]

[Problems to be solved by the device]

 The object of the present invention is to provide a smooth and quiet lifting function while maintaining the advantages of the two-point support care trolley, and to solve the problems of both conventional two-point support and four-point support configurations. It is about to provide a new nursing trolley to solve.

[0005]

[Means for Solving the Problems]

 The present invention slidably mounts a pedestal on a support means installed at one end of the base of a nursing trolley, and a booster composed of a pulley, a drum, and a wire between the pedestal and the pedestal. The above problem is solved by providing an elevating mechanism that is a combination of mechanisms.

[Industrial application] The present invention can be used easily and safely by a care trolley, and more specifically, by a person who is impaired in his / her free behavior such as a sickness / medicine patient, a bedridden elderly person, or a physically handicapped person. Regarding care trolley.

[0002]

[Prior Art and Problems] A care trolley is a support pedestal on which a patient or the like should be placed on a base having a caster for traveling at the bottom, and is used for illness / medical patients, bedridden elderly, and physical bodies. It is widely used as a means of transportation for people with disabilities who have been deprived of physical freedom. Conventionally, a four-point support trolley for supporting the pedestal stably by erected support means at the four corners of the base was common, but nowadays it is erected at the two corners at one end in the longitudinal direction of the base. A structure with two-point support in which the base is fixedly supported by the above-mentioned supporting means and the base and the base on the other end side are open is provided, and the field of adoption is expanding. This is because when using a care trolley that supports two points, the treatment table, work table, bed, etc. can be sandwiched and positioned in the open space formed between the base and the gantry. In addition to reducing the area, it is convenient for medical / nursing work while being placed on the pedestal and for moving the pedestrian between the pedestal and other positions (for example, treatment table, work table, bed, etc.). This is because there are many cases in which An example of this is bathing care at medical and nursing care facilities. That is, in recent medical and nursing care facilities, in order to eliminate the burden and danger at the time of bathing care, a nursing bathing device (a water receiving tank is provided in the middle part of the base body to divide and form empty space above and below, and the empty space above the shower room In the shower room, the bather is accommodated and supported in the shower room above the water tank, and the applicant applies for a utility model registration, which was also proposed at the same time. Has been applied for). With this care bathing device, a two-point support care trolley allows bathing care while the bather is placed on the cradle with a water receiving tank sandwiched between the base and the cradle. With a four-point support care trolley, the bather needs to be moved from the gantry to the shower room and supported above the water tank, so the care burden cannot be reduced.

As described above, the two-point support care trolley has been recognized to have a great advantage, but on the other hand, it is difficult to provide the pedestal with an elevating function. This is a four-point support care trolley. This is a big problem when compared to a trolley for use. That is, various patient mounting means such as a treatment table, a work table, and a bed have a surface height according to the purpose of the work, and if the platform of the care trolley cannot be adjusted up and down according to each height. This is because the transportation, treatment, and nursing services must be significantly hindered. In this respect, the four-point support care trolley originally has a stable structure in which the pedestal is supported by the support means set up at the four corners, and it is only necessary to attach an optional elevator mechanism to these support means. It is possible to easily assure a smooth and quiet lifting function. On the other hand, since the two-point support care trolley only has to provide the support means on one end side in the longitudinal direction of the base / frame, smooth and quiet elevation can be obtained even if a normal elevating mechanism is optionally attached. However, it was not possible to deny even the risk of causing anxiety to the mounter due to unpleasant vibrations and intermittent lifting and lowering the stability of the mount itself.

[0004]

[Problems to be Solved by the Invention] The problem to be solved by the present invention is to provide a smooth and quiet lifting function while maintaining the advantages of a two-point support nursing care trolley. This is to provide a new care trolley that solves the problems of both configurations.

[0005]

[Means for Solving the Problems] The present invention is to slidably mount a pedestal on a support means erected on one end side of a base of a care trolley, and to elevate and lower between the pedestal and the pedestal. The above problem is solved by interposing a mechanism.

An embodiment of a nursing care trolley according to the present invention will be described below with reference to FIGS. 1 to 3.

The care trolley according to the present invention comprises a base frame 1 provided with a traveling means and a support means, and a gantry frame 2 provided with a fitting means capable of being fitted to the support means of the base frame 1. By fitting the mounting means of the gantry frame 2 to the supporting means of the pedestal frame 1 in a slidable manner, the gantry frame 2 is supported at the upper position of the pedestal frame 1, and at the same time, it is composed of a pulley, a drum and a wire. An elevating mechanism combined with a force mechanism is provided to ensure the elevating and lowering of the gantry frame 2. Here, the base frame 1 is a substantially U-shaped frame body made of metal or other appropriate hard material, and has an appropriate number of running casters 10 on the bottom thereof and a mount at one corner in the longitudinal direction. The guide rails 3 that support the frame 2 are set up at appropriate angles. Similarly, the other gantry frame 2 is also a substantially U-shaped frame body made of a hard material, and has an area sufficient for placing a patient on its flat surface, and the base frame 1 is provided at one corner on one side in the longitudinal direction. A fitting portion 4 is provided which is formed so as to be fitted with the guide rail 3 of FIG. In addition, the lifting mechanism of the gantry frame 2 has pulleys 2a and 1d attached to each of the horizontal rails 6 of the gantry frame 2 and the horizontal rails 7 of the base frame 1, and one end of the pulleys 2a and 1d is fixed to the horizontal rail 7. The wires 8 are successively connected, and the open end of the wire 8 is connected to the drum 1c having the smaller diameter of the two drums 1c and 1d arranged concentrically, and the drum 1d having the larger diameter and the handle are connected. The drum 1a pivotally attached to 9 is connected by a wire 8 '.

Since the care trolley according to the present invention has the above-mentioned structure, the rotation of the drum 1a by the operation of the handle 9 causes the drum 1d connected by winding the wire 8'to rotate. The drum 1c, which is arranged concentrically with the drum 1d, rotates and pulls the wire 8 which is connected to the drum 1c. Further, as the wire 8 is wound and pulled, the pulley 2a and the cross rail 6 to which the pulley 2a is attached are lifted and lifted, and the frame frame slidably fitted to the guide rails 3 of the base frame 1. Raise M2. It goes without saying that the descent is brought about by the reverse operations and operations described above. As is clear from the above, the lifting and lowering of the gantry frame 2 in the care trolley according to the present invention involves the first booster mechanism in which the pulley 1d is the fixed pulley and the pulley 2a is the movable pulley, and the drum 1c having a different diameter. 1d is concentrically arranged in combination with the second booster mechanism, so despite the extremely simple and lightweight structure, no one needs any special force to move smoothly and quietly. Can be done.

In the illustrated embodiment, it is assumed that the care trolley according to the present invention is used for bathing care work using a care bathing apparatus, and the bather mounting surface of the gantry frame 2 is constituted by the net 11. However, its material and shape should not be limited. The selection is arbitrary depending on the intended use and purpose of the nursing care trolley or the holder, and the care trolley may be detachably configured.

Further, the lifting mechanism shown in the figure is merely an example, and the design of the fixed end of the wire is first selected, and the design selection of the connection and the connection, and the shape, diameter, position and number of the pulley and the drum to be arranged. All of these should be decided purposely. Further, it goes without saying that the structure for fitting / supporting the base frame 1 and the gantry frame 2 is not limited to the combination of the fitting portion 4 in which the guide rail 3 and the roller 5 shown in the figure are installed. In addition, it should be noted that the lifting mechanism for the nursing care trolley according to the present invention is not necessarily limited to the combination of the booster mechanism including the pulley, drum, and wire, and the smooth and quiet lifting function is provided. As long as it can be secured, it does not prevent the use of other means. The hydraulic mechanism shown in FIG. 4 is most suitable as the lifting mechanism other than the embodiments shown in FIGS. For example a hydraulic cylinder was attached to fitted means bridging table frame 2 to fit freely support means and the sliding of the base frame 1, a hydraulic pump to be driven to this, the electric motor, as well as each of the rechargeable battery Taking the structure, such as disposed on the base frame 1 rear other suitable Yichun position, thereby lifting the frame frame 2 smoothly and quiet by a simple hydraulic mechanism while maintaining the basic structure of the two-point support. In particular, in the embodiment shown in FIG. 4, and the hydraulic cylinder unit is swingably provided, et al is within a certain range, by configuring to beat during descent causes rise it while increasing the gantry frame 2, a good The lifting stroke is secured.

[0011]

As described above, according to the nursing care trolley of the present invention, while maintaining the advantages of the conventional two-point support nursing care trolley as it is, the smoothness that could not be realized up to now is achieved. Therefore, it is possible to secure a quiet raising and lowering function, and it is possible to completely eliminate and eliminate the problems that both the two-point support and four-point support care trolleys have.
