[Industrial applications]

 The present invention relates to a catering car used in, for example, a hospital having a large number of inpatients.

[0002]

[Prior art and its problems]

 Conventionally, as this type of trolley, the main body of the trolley has been designed to accommodate a plurality of tiers of trays inside, and the wheels can be attached to the bottom of the main body to make it movable. The hand-held type is widely used.

[0003] By the way, this type of serving car is for storing and transporting food, and from the viewpoint of hygiene maintenance, a stainless steel plate is generally used as a main constituent of the serving body so that it can be washed as a whole. It is used for. For this reason, the total weight is often very heavy, reaching 150 to 300 kg, and a great deal of labor is required for the transportation work.

For example, even if an attempt is made to stop the catering car from the moving state, the catering car does not immediately stop due to its inertia. Particularly, the heavier the catering car, the more difficult the braking and stopping work is.

[0007] Furthermore, there are not a few sloped passages in actual use sites, and when transporting a vehicle downhill on such a route, the vehicle itself is rather heavy as described above. One person may not be able to apply sufficient braking force, and sometimes a dangerous runaway condition may occur. Under such circumstances, the transportation work of this type of catering car is a heavy labor for one person, and for example, when braking is stopped or when the vehicle is traveling downhill, it may be forced to be carried out by a plurality of people including other workers. For example, the labor required for the transportation work tends to be excessive.

[0006] Furthermore, depending on the serving place, it may be necessary to stop the vehicle at a place having a slope. In this case, the serving work cannot be performed unless the vehicle is completely stopped. For that purpose, it is necessary to take various stop securing measures such as engaging the wheels with stoppers, but the stop securing operation was also a little troublesome.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a food distribution vehicle having a braking function, which is capable of easily and surely performing a braking stop operation. To do.

[0008]

[Means for Solving the Problems]

 Thus, this invention is, in essence, provided with a braking function and also with a braking lock function capable of locking the braking state.

[0009] That is, the present invention relates to a wheeled vehicle in which wheels are attached to a bottom surface of a food storage main body so as to be freely movable, and the wheel braking portion and the brake of the braking portion attached to a side surface of the main body of the food storage compartment. The braking operation unit that controls the operation and the release operation, the braking unit and the operation unit are connected to each other, and the braking force transmission line such as a wire that is constantly urged toward the braking unit side and the braking force transmission line during braking are connected. A braking lock means for locking and maintaining a braking state is provided, and the braking lock means includes a lock lever pivotally mounted on a side surface of the food storage main body and a lock portion provided on the braking force transmission line. The lock lever has a locking portion that is locked to the lock portion by rotating the locking lever in the locking direction during braking operation, and is always biased in the locking releasing direction. Be something It is an gist servings vehicle characterized.

The lock lever has a fitting edge portion such as a wire formed with a fitting slit into which a braking force transmission line such as a wire can be fitted from the side when the lock lever is rotated in the locking direction. On the other hand, a lock ring that is fixed to the braking force transmission cable as a lock part and has a size that can be locked to both side edges of the fitting slit is used. Along with the operation, it may be moved between the braking operation portion side position and the wheel braking portion side position with the fitting position between the fitting edge portion and the wire or the like as a boundary.

[0011]

[Action]

 By braking the braking operation portion, the wheel braking portion is actuated via the braking force transmission line, and the wheel is brought into a braking state.

By this braking operation, the lock portion fixed to the braking force transmission line is braked from the position on the wheel braking portion side with the intersection of the locking portion of the lock lever and the transmission line as a boundary with the movement of the transmission line. Move to the department position.

In this braking operation state, when the lock lever is rotated in the locking direction, the locking portion comes into contact with or comes close to the braking force transmission cable.

When the braking operation of the braking operation section is released in this state, the braking force transmission line automatically moves to the wheel braking section side, and the lock section also moves in the same direction accordingly. Then, the lock member is locked to the locking portion of the lock lever, and the movement of the braking force transmission line is blocked. When the locking portion is locked to the lock portion in this way, the frictional force prevents the lock lever from rotating in the unlocking direction. Therefore, even if the braking operation of the braking operation unit is released, the braking lock state is maintained.

Subsequently, in the braking locked state, when a braking operation is performed by the braking operation unit, the braking force transmission line is once pulled to the braking operation unit side, and the lock unit also moves in the same direction accordingly. Then, the locked state between the lock part and the lock part of the lock lever is released, and the lock lever is automatically rotated in the locking release direction to return to the original position. By once releasing the braking operation as described above, the braking force transmission line is allowed to move toward the braking portion side, and the braking of the wheel by the braking portion is released.

The braking portion (7) is pivotally attached to the upper side edge of the fixed plate (8) arranged outside the large wheel (2) and presses the upper bent edge (9a) against the wheel outer peripheral surface. The braking plate (9), which is adapted to perform the above operation, is disposed between the lower end edge portion (9b) of the plate (9) and the lower portion of the same side edge of the fixed plate (8), and the upper end It is composed of a spring (10) for urging the bent edge portion (9a) in a direction away from the outer peripheral surface of the wheel.

The braking plates (9) (9) arranged at the left and right corresponding positions are connected at their lower end edges (9b) (9b) to each other by the interlocking operation rod (11), By pulling the operating rod (11) upward, the left and right braking plates (9) (9) can be operated simultaneously.

On the other hand, concave sides (12a) extending in the left-right direction are formed on side surfaces (12) (12) of the main body (1) of the food handling operation side on the carrying operation side (side surface of the main body of the food storage). Then, as shown in FIG. 3, the transfer operation pipes (13) (13) which are bent in a U-shape that spreads toward the bottom and are located in the respective recessed surface as shown in FIG. The operation side surfaces (12) (12) are arranged so as to project from the side surfaces (12) (12). As shown in FIG. 1, the carrying operation pipe (13) has a pair of left and right lower mounting pieces whose lower ends (13a) are fixed to both ends of the lower end of the recess (12a) in a protruding state. While being fixed to (14), the horizontal part (13b) is fixed to the upper mounting piece (15) fixed to the center of the upper part of the concave part (12a) in a protruding state.

At a position slightly to the right of the center of the horizontal portion (13b) of the transfer operation pipe (13), a braking operation portion (16) for controlling the braking operation and the releasing operation of the braking portion (7) is attached. Has been.

As shown in FIG. 4, the braking operation part (16) has a bracket (17) fixed to the horizontal part (13b) of the pipe (13) and a base end part (18a) pivotally attached thereto. And an operating lever (18).

As shown in FIG. 1, the braking operation part (16) and the braking part (7) are arranged along the bottom surface (1a) and the side surface (12) of the serving main body (1), respectively. It is connected by a brake wire (braking force transmission line) (19) provided. Then, when the operation lever (18) is squeezed, the wire (19) is attached to the lower edge of the side surface (12) of the main body of the food storage and the pulley arranged on the upper part of the interlocking operation rod (11). (20) It acts so as to pull up the operating rod (11) via (20). When the operating rod (11) is pulled up in this way, the lower end edge (9b) of the braking plate (9) is rotated in the lifting direction against the biasing force of the spring (10), and the upper end bent edge (9a). ) Is pressed against the outer peripheral surface of the large wheel (2) to enter a braking state.

[0028] This delivery car (A) has not only the above braking function but also a braking lock function for locking the braking state.

This braking lock function is achieved by the braking lock means (21) arranged in the recess (12a).

As shown in FIG. 4, the braking lock means (21) is pivotally attached to the intermediate bent bulge (22a) of the lock lever mounting bracket (22) mounted in the recess (12a). The lock lever (24) is rotatably pivoted by a wire 23 and a lock member (lock portion) (25) fixed to the wire (19).

The mounting bracket (22) has a protruding edge portion (22b) which is bent and protruded from an upper end of the mounting bracket (22), and the wire (19) extends through the central portion of the protruding edge portion (22b). It is arranged. The wire (19) located between the protruding edge portion (22b) and the braking operation portion (16) is covered with an outer cable (26). The lock lever (24) is made of an angle member having a substantially L-shaped cross section composed of a vertical piece (24a) and a horizontal piece (24b), and one end of the vertical piece (24a). Is pivotally attached to the middle bent bulge (22a) of the bracket (22) by the pivot (23).

The lock lever (24) is wound around the pivot shaft (23) so that one end thereof is locked to the intermediate bending bulge (22a) of the bracket (22) and the other end thereof is locked. The spring (27) locked to the bar (24) urges it to rotate in the clockwise direction, and is normally abutted against the protruding edge portion (22b) as shown by the phantom line in FIG. There is. When the free end of the lock lever (24) is pushed down by hand, the lock lever (24) is rotated counterclockwise (rocking direction) about the pivot (23) against the biasing force of the spring (27). When the hand is released, the spring (27) urges it to rotate clockwise (locking release direction) and return to the original position.

Further, the wire (19) is fitted from the side to the base end side edge of the horizontal piece (24b) of the lock lever (24) at the time of the rocking rotation operation of the lever (24). A wire fitting slit (28) that can be fitted is formed. Thus, the horizontal piece portion (24b) has a wire fitting edge portion (locking portion) (29) at its base end side edge portion.

On the other hand, the lock member (25) is composed of a cylindrical body having a diameter larger than the width of the fitting slit (28), and is used for the braking operation and the releasing operation of the braking operation section (16). Accordingly, it moves between the braking operation part side position and the wheel braking part side position with the fitting position of the fitting edge part (29) and the wire (19) as a boundary. In the figure, (30) is a protective cover.

Therefore, by pushing down the operation lever (18) of the braking operation unit (16), the wheel braking unit (7) is operated via the brake wire (19) and the wheel (2) is in the braking state. Becomes By this braking operation, the lock member (25) fixedly attached to the brake wire (19) causes the wire fitting edge portion (29) of the lock lever (24) and the wire (19) as the wire (19) moves. The vehicle moves from the position on the wheel braking unit side to the position on the braking operation unit side with the fitting position of as a boundary.

In this braking operation state, when the lock lever (24) is rotated counterclockwise, the wire (19) is fitted in the wire fitting slit (28) of the wire fitting edge portion (29). To be done.

In this wire fitting arrangement state, when the pushing operation of the operation lever (18) of the braking operation section (16) is released, the wire (19) automatically moves to the wheel braking section (7) side, Along with this, the lock member (25) also moves in the same direction. However, since the wire (19) is fitted and arranged in the wire fitting slit (28), the lock member (25) is locked at both side edges of the fitting slit (28). Movement of (19) is blocked. When the lock member (25) is locked to the wire fitting edge portion (29) in this manner, the frictional force of the lock member (25) prevents the lock lever (24) from rotating in the clockwise direction. Therefore, the braking lock state is maintained even if the braking operation of the braking operation section (16) is released.

Next, in order to release the braking lock state, it is sufficient to push down the operation lever (18) of the braking operation unit (16) and release it. That is, when the lever (18) is pushed down, the wire (19) is once pulled up, and the lock member (25) also moves in the same direction accordingly. Then, the locked state between the lock member (25) and the fitting edge portion (29) of the lock lever (24) is released, the frictional force between the two is reduced, and the lock lever (24) is biased by the spring (27). ) Automatically rotates clockwise and returns to its original position. In this way, once the braking operation is performed and then released, the braking lock state is released.

It should be noted that, by providing the braking operation portion and the braking lock means on both front and rear sides of the main body of the car as in the above embodiment, the braking and releasing operations can be performed from both front and rear sides. It is convenient, but of course, it may be provided only on the pushing operation side of the main body of the catering cabinet.

Further, as the braking transmission cable, a thin rod-shaped member or the like may be used instead of the wire shown in the above embodiment, and the locking portion of the lock lever may be replaced with a wire fitting slit. Any other structure may be used as long as it can simply lock the lock portion.

[0041]

[Effect of the device]

Since it is provided with the braking operation unit, it is possible to easily and surely stop or adjust the speed by operating the braking operation unit when the braking is stopped and when the vehicle is transported downhill. Therefore, even if the vehicle is heavy, no great effort is required for stopping the braking and carrying the vehicle downhill. In particular, it is not necessary for two or more people to carry out the work to prevent runaway when carrying a downhill, and one person can carry it safely.

Moreover, since the braking lock means for locking the braking force transmission line during braking to maintain the braking state is provided, the movement preventing state can be easily and reliably arranged in any place regardless of the presence or absence of the gradient. The car can be held stationary.

Further, the brake lock means is composed of a lock lever pivotally mounted on the side surface of the main body of the food storage and a lock portion fixed to the transmission line, and therefore has a simple structure. There is no increase in manufacturing cost.

Moreover, the lock lever has a locking portion that is locked to the lock portion by being rotated in the locking direction during braking operation, and is always biased in the locking release direction. is there. Therefore, the braking lock operation can be performed easily by braking the braking operation portion, then rotating the lock lever to bring the locking portion into contact with the braking force transmission line, and releasing the braking operation in that state. Can be done.

On the other hand, the braking lock releasing operation can be performed by an extremely simple and easy operation in which the braking operation unit once performs the braking operation in the braking locked state, and then the braking operation is released.
