Hereinafter, a carriage according to the present embodiment will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a plan view of a carriage 10 according to the first embodiment. FIG. 2 is a bottom view of the carriage 10. FIG. FIG. 3 is a front view of the carriage 10. FIG. FIG. 4 is a rear view of the carriage 10. FIG. FIG. 5 is a side view of the carriage 10. FIG. 4 and 5 show a state in which the hand pushing member 40 is attached to the carriage 10. As shown in FIG.
In each figure, for convenience, the arrow Fr is the front side, the arrow Rr is the rear side, the arrow R is the right side, the arrow L is the left side, and the center of the lateral length of the carriage 10 is indicated as the center line C1. However, the carriage 10 can travel in any of the front, rear, left, and right directions on the travel surface. Moreover, the carriage 10 is substantially symmetrical with respect to the center line C1.

The carriage 10 includes a carriage body portion 20 and a traveling portion 30 .
The trolley main body 20 is configured by connecting a plurality of frame parts and the like, and loads objects to be transported thereon. The carriage main body 20 has a substantially rectangular shape with a longitudinal direction (first direction) as a longitudinal direction and a lateral direction (second direction) orthogonal to the longitudinal direction as a lateral direction in a plan view. The length of the carriage main body 20 in the longitudinal direction is, for example, 1200 mm, and the length in the lateral direction is, for example, 750 mm. Further, the height from the running surface to the upper end (upper surface) of the carriage main body 20 is, for example, 250 mm. The carriage main body 20 is substantially symmetrical in the front-rear direction with respect to a straight line passing through the center in the longitudinal direction in a plan view and extending in the left-right direction. The carriage main body 20 has a front frame portion 21 a , a rear frame portion 21 b , a right frame portion 21 c , a left frame portion 21 d , corner portions 22 and reinforcement portions 25 .

The front frame portion 21 a , the rear frame portion 21 b , the right frame portion 21 c and the left frame portion 21 d form the outline of the carriage body portion 20 . The front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, and the left frame portion 21d are joined at four corners by corner portions 22 to form a substantially rectangular four-sided frame. . For the front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, and the left frame portion 21d, for example, rectangular hollow pipes made of aluminum alloy can be used.

The corner portion 22 connects adjacent frame portions among the front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, and the left frame portion 21d at four corners. Further, the corner portion 22 functions as an attachment portion for attaching the hand pushing member 40 to the carriage main body portion 20 . The corner portion 22 has an insertion hole 23 that opens upward and into which the push member 40 is inserted, and a support portion 24 that supports the push member 40 inserted into the insertion hole 23 . For the corner portion 22, for example, a member made of an aluminum alloy formed by extrusion can be used.

The reinforcing portion 25 reinforces the four sides of the frame of the bogie body portion 20 . Specifically, the reinforcing portion 25 has reinforcing frame portions 26a, 26b, 26c and mounting members 28a, 28b.
The reinforcing frame portions 26a, 26b, and 26c reinforce the carriage main body portion 20 by abutting the four frame frames or each other in the front, rear, left, and right directions and being joined by bolts, rivets, welding, or the like. In this embodiment, two reinforcing frame portions 26a and 26b extending in the front-rear direction are provided across the front frame portion 21a and the rear frame portion 21b. A total of 12 reinforcing frame portions 26c along the left-right direction are constructed over the right frame portion 21c and the reinforcing frame portion 26a, the reinforcing frame portion 26a and the reinforcing frame portion 26b, and the reinforcing frame portion 26b and the left frame portion 21d. be done. For the reinforcing frame portions 26a, 26b, and 26c, square hollow pipes made of aluminum alloy, for example, can be used. The width dimension Wr of the reinforcing frame portions 26a, 26b, and 26c is smaller than the width dimension Wm of the front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, and the left frame portion 21d. Further, the height dimension Hr of the reinforcing frame portions 26a, 26b, and 26c is substantially the same as or slightly smaller than the height Hm of the front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, and the left frame portion 21d (Fig. 9). The width dimension Wr of the reinforcing frame portions 26a, 26b, and 26c is smaller than the height dimension Hm. The carriage main body 20 has a plurality of rows (three rows) of space formed along the front-rear direction in plan view by the reinforcement frame portions 26a and 26b, and a plurality of rows (five rows) of spaces along the left-right direction in plan view by the reinforcement frame portion 26c. A plurality of (total 15) substantially rectangular spaces 27 are formed by forming the spaces of the column.

The mounting members 28a and 28b reinforce the carriage main body 20 by being joined from below to the four frames and reinforcing frame portions 26a, 26b and 26c by bolts, rivets, welding or the like. Moreover, the mounting members 28 a and 28 b have a function of mounting the casters 31 A and 31 B to the carriage main body 20 . In this embodiment, the mounting members 28a are positioned in the spaces 27 at the four corners adjacent to the four corners 22, and the mounting members 28b are positioned in the left and right spaces 27 with the central space 27 interposed therebetween. The mounting members 28a and 28b have a shape in which corners of a rectangular shape are notched in plan view or bottom view. For example, metal plates or the like can be used for the mounting members 28a and 28b. The space 27 in which the mounting members 28a and 28b are arranged in the space 27 is open on the upper side, and most of the lower side is closed by the mounting members 28a and 28b. When the same carriages 10 are stacked, casters 31A and 31B, which will be described later, of the upper carriage 10 enter into the space 27 whose lower portion is mostly closed by the mounting members 28a and 28b. On the other hand, the space 27 in which the mounting members 28a and 28b are not arranged penetrates vertically.

When loading an object on the carriage main body 20, the object can be loaded by placing it on the front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, the left frame portion 21d, and the reinforcing portion 25. .

The traveling portion 30 travels on the traveling surface while supporting the load of the carriage body portion 20 and the transported object. The traveling part 30 has a plurality of casters 31A and 31B.
The casters 31A are positioned at four corners of the carriage body 20 and attached to the carriage body 20 via attachment members 28a. The casters 31B are positioned at the center of the truck main body 20 in the front-rear direction and separated from each other in the left and right directions, and are attached to the truck main body 20 via the mounting members 28b. The casters 31A and 31B can turn around a turning axis O1 along the vertical direction.

Casters 31A positioned at the four corners are casters with brakes that can be braked or released according to user's operation. On the other hand, the caster 31B positioned in the center is a caster without a brake. Here, the configuration of the caster 31A will be described. The caster 31B has a structure in which the brake function is omitted from the caster 31A.

As shown in FIG. 5, the caster 31A has wheels 32, a support portion 33, a brake pedal 36, and a turning portion 38. As shown in FIG. The wheel 32 has a wheel portion having a bearing built therein and a tire portion fitted to the outer periphery of the wheel portion. The support portion 33 rotatably supports the wheel 32 via an axle. The support portion 33 has a fork member 34 that supports the wheel 32 and a pedal holding member 35 that holds the brake pedal 36 so as to be vertically swingable. The fork member 34 is integrally formed with a pair of side walls located on both sides of the wheel 32 and a top plate connecting the pair of side walls above the wheel 32 . The top plate is rotatably held by a rotatable portion 38 . The pedal holding members 35 are positioned on both sides of the wheel 32 and integrally formed of a pair of side walls fixed to the fork member 34 and a connecting plate connecting the pair of side walls on the upper side. The brake pedal 36 is vertically swingable with respect to the pedal holding member 35 . The brake pedal 36 has an operating portion 37 . Up and down swing of the brake pedal 36 is operated by the operation unit 37 by the foot of the user.

With the brake released, the brake pedal 36 is in the raised position. On the other hand, when the user depresses the operation portion 37 of the brake pedal 36 downward with his or her foot, the brake pedal 36 swings downward against the force of the spring. The brake pedal 36 shown in each drawing is in a state in which the brake is released. As the brake pedal 36 swings downward, the brake pedal 36 directly or indirectly strongly presses the outer peripheral surface of the wheel 32, so that the wheel 32 cannot rotate and the brake is applied. . Also, the brake pedal 36 functions as a stopper because it is held in a brake-applied state. The turning portion 38 turns the wheel 32 , the support portion 33 and the brake pedal 36 .

Here, the caster 31A has been described, but the caster 31B has a configuration in which the member related to the brake is omitted from the caster 31A. That is, the caster 31B has the wheels 32, the support portion 33, and the turning portion 38, but does not have the brake pedal 36. As shown in FIG. Therefore, like the caster 31A, the caster 31B can turn about the turning axis O1 via the top plate of the fork member 34, but cannot be braked.
Further, the casters 31A and 31B are set at positions where the ground contact position of the wheel 32 and the turning axis O1 are eccentric in plan view. Therefore, the wheels 32 of the casters 31A and 31B turn about the turning axis O1 so as to be opposite to the traveling direction with the turning axis O1 interposed therebetween.

In FIG. 2, the trajectory TA1 of the wheel 32 and the trajectory TA2 of the brake pedal 36 when the caster 31A turns around the turning axis O1 are indicated by two-dot chain lines. The trajectory TA1 of the wheels 32 of the caster 31A fits within the four frame frames without protruding outside the four frame frames in plan view. That is, the trajectory TA1 of the wheel 32 of the caster 31A fits inside the outer peripheral edges of the four frames. On the other hand, a part of the trajectory TA2 of the brake pedal 36 of the caster 31A protrudes outside the four frames in a plan view. Although only the trajectory TA1 of the wheel 32 of the front caster 31A and the trajectory TA2 of the brake pedal 36 are shown here, the rear caster 31A has the same trajectory.
Further, in FIG. 2, the trajectory TB of the wheel 32 when the caster 31B turns around the turning axis O1 is indicated by a chain double-dashed line. The trajectory TB of the wheels 32 of the caster 31B fits within the four frame frames without protruding outside the four frame frames in plan view. That is, the trajectory TB of the wheel 32 of the caster 31B fits inside the outer peripheral edges of the four frames.

Further, the carriage 10 can be attached with a hand pushing member 40 for the user to manually push when the carriage 10 is driven. In each figure, the pushing member 40 is indicated by a chain double-dashed line. The hand pushing member 40 is a member for a user to hold the hand when the carriage 10 is driven. A user grips and pushes or pulls the hand pushing member 40 to move the carriage 10.例文帳に追加The push member 40 is attached to the carriage main body 20 by inserting the push member 40 into the insertion hole 23 of the corner portion 22 , and removed from the carriage main body 20 by extracting the push member 40 from the insertion hole 23 . The hand pressing member 40 is a rod-shaped member elongated in the vertical direction. For the pushing member 40, for example, a member made of an aluminum alloy formed by extrusion molding or the like can be used, or a single tube (single tube pipe) can be used. A single pipe refers to a carbon steel pipe for general structural use defined in JIS G 3444, and is a circular pipe with an outer diameter of 48.6 mm.
