Description

[Technical field]

[0001] The present invention relates to a wheel stopper for a bogie, and more particularly to a wheel stopper for a bogie that reliably fixes a rotatable wheel and is compatible with the wheel diameters of different bogies. [Background technology]

[0002] Conventionally, wheel stoppers for trolleys, which stop the wheels on a trolley or the like from rolling and brake the trolley, include one having a film-like layer attached as in Patent Document 1, and one having a main body with a wheel retraction guide wall and a wheel mounting portion as in Patent Document 2. However, such a wheel stopper for a trolley may not be able to accommodate a wheel diameter of a different trolley, and since flatbed trucks in particular have rotatable wheels, the trolley wheel stopper itself may slip and lose its control function. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Mito 3138688 [Patent Document 2] Real climb 3196578 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 describes a braking device for a cart with casters having a slope that receives the rolling of the wheels of the cart with casters, in which a film-like layer having a thickness necessary for the wheels to ride up without resistance is affixed to the contact surface side, and the film-like layer has an extension that extends from the lowest edge of the slope in the wheel direction along the installation surface on which the braking device for the cart with casters is provided, and the wheels roll to freely ride up onto and off the upper surface of the extension. In Patent Document 1, the wheels rest on the upper surface of the extension part when the horizontal state is not maintained, which provides a fixing effect. However, in a horizontal state, the wheels do not rest on the upper surface of the extension part, so the fixing force is weak. Therefore, it is desirable to have a wheel stopper for a dolly that has a fixing force even when the wheel is in a horizontal position and that prevents the wheel from coming off.

[0005] Patent Document 2 discloses a wheel stopper for a trolley, which includes a main body having a pair of wheel retraction guide walls and a wheel mounting part, the pair of wheel retraction guide walls being arranged opposite each other with a gap therebetween, and the wheel mounting part having a protrusion provided between the pair of wheel retraction guide walls. The protrusion provided between the wheel retraction guide walls limits the movement of the wheel in the left-right direction (direction perpendicular to the rotation direction), and the protrusion on the wheel mounting part limits the movement of the wheel in the front-rear direction (rotation direction), so that the wheel can be fixed even when a rotatable wheel on a trolley is stopped. Although the wheel stopper in Patent Document 2 can accommodate a certain range of wheel diameters, it cannot accommodate wheel diameters that vary greatly. Therefore, a wheel stopper for a bogie that can accommodate various wheel diameters is desired.

[0006] There is also a need for a wheel stopper for a trolley that can securely hold rotatable wheels. In particular, since flatbed trucks have rotatable wheels, the trolley wheel stopper itself can slip and lose its control function, so a stopper that can securely hold the wheels is desirable.

[0007] It is also necessary that the trolley can be used regardless of its wheel diameter. Many fasteners are compatible only with a specific wheel diameter, and a fastener that can be used with a variety of trolleys and usage environments is required. In addition, a fastener that can securely fix the wheels is required even if the wheel installation area becomes large due to the weight of the cargo. Such a fastener improves the safety of the trolley and enables it to be used in a variety of environments.

[0008] To provide a wheel stopper for a dolly which can reliably fix a rotatable wheel, can accommodate different wheel diameters of dollies, and can insert the wheel even if the wheel installation area becomes large due to the weight of the luggage. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the present invention provides a wheel stopper for a trolley comprising a main body, a first block and a second block, and a connecting member, the connecting member being connected to the main body and connecting the first block and the second block, the connecting member and the main body being configured such that convex portions at both ends of the connecting member engage with concave portions at both ends of the main body, and the main body can rotate up to an angle of 90 degrees, and the first block and second block are pressed against the wheels by the elastic force of a tension coil spring attached inside the connecting member.

[0010] The main body is a wheel stopper for a dolly and includes a magnet portion.

[0011] The connecting member has a first slit portion and a second slit portion at both ends, and the first block and the second block have insertion pieces at one end, which can be inserted into the slits at both ends of the connecting member and slid linearly toward the center of the connecting member, thereby providing a wheel stopper for a trolley. Effect of the Invention

[0012] Therefore, when using the wheel stopper for a dolly, first, the first block and the second block are spread apart slightly wider than the width of the wheel against the force of the tension coil spring, the wheel is sandwiched between the first block and the second block, and then when the fingers are released, the elastic force of the tension coil spring presses the first block and the second block against the wheel, thereby fixing the wheel. Also, when the main body is rotated 90 degrees to stand up, the magnet part of the main body is magnetically attracted to the metal part of the wheel and fixed in place. By providing the magnet part, the freely rotatable wheel can be firmly fixed.

[0013] The wheel stopper for a trolley in Patent Document 2 does not accommodate different wheel diameters. The wheel diameters of general trolleys are φ75, φ100, φ125, and φ130, and the present invention accommodates these different wheel diameters. The first block and the second block can be expanded to any width.

[0014] In the present invention, the wheel is sandwiched between the first block and the second block from both sides, and furthermore, the magnet part is magnetically attracted to the metal part of the caster, so that the wheel is firmly fixed in place. [Brief description of the drawings]

[Figure 4] FIG. 2 is a perspective view of the wheel stopper for a bogie disassembled into its individual components. [Diagram 5] FIG. 1 illustrates a method of using the present invention. [Figure 6] FIG. 1 illustrates a method of using the present invention. [Figure 7] FIG. 1 is a diagram showing a storage method of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Fig. 1 is a perspective view showing one embodiment of the wheel stopper for a dolly of the present invention. Fig. 3 is a perspective view of the wheel stopper for a dolly from the back side. The wheel stopper for a dolly of the present invention has a rib on the back side, and is preferably made of resin. Fig. 4 is a perspective view of the wheel stopper for a dolly disassembled into parts.

[0017] As shown in Fig. 1, a wheel stopper 1 for a dolly includes a main body 2, a first block 3, a second block 4, and a connecting member 5. The first block 3 and the second block 4 are wedge-shaped, and the inclined surfaces 32 and 42 thereof fix the wheels.

[0018] Fig. 2 is a perspective view showing the state in which the body 2 of the wheel stopper 1 for a dolly is rotated 90 degrees and stands upright. The wheel stopper 1 for a dolly can be used both in the state shown in Fig. 1 and in the state in which the body 2 stands upright as shown in Fig. 2. The body 2 includes a magnet portion 21, and a magnet 22 (not shown) is inserted on the back side thereof.

[0019] Fig. 3 is a perspective view of the wheel stopper for a bogie from the back side. Fig. 4 is a perspective view of the wheel stopper for a bogie disassembled into its parts. As shown in Figs. 3 and 4, the connecting member 5 is provided with a tension coil spring 53 on the inside.

[0020] Next, a method for fixing a wheel using the wheel stopper 1 for a carriage will be described. First, bring the first block 3 and the second block 4 close to the wheel and spread them apart. At that time, it is recommended to place the wings 31 and 41 on your fingers to spread them apart. Spread them slightly wider than the width of the wheel against the force of the spring, pinch the wheel between the first block 3 and the second block 4, and then release your fingers. At that time, the wheel is fixed in place by the elastic force of the tension coil spring 53 as it tries to return to its original shape.

[0021] That is, a wheel is placed between the inclined surfaces 32 and 42 of the first block 3 and the second block 4, and the elastic force of the tension coil spring 53 presses the first block 3 and the second block 4 against the wheel.

[0022] The connecting member 5 in FIG. 4 has two functions: (1) to connect the connecting member 5 to the main body 2, and (2) to connect the connecting member 5 to the first block 3 and the second block 4.

[0023] (1) The connection between the connecting member 5 and the main body 2 will be described below. The connecting member 5 has protrusions 58 and 59 on both sides in the A-A' direction. The main body 2 has recesses 23 and 24 on both sides in the A-A' direction. The connecting member 5 and the main body 2 are connected by the engagement between the protrusion 58 and the recess 23, and the engagement between the protrusion 59 and the recess 24, respectively.

[0024] This engagement has the property that the body 2 can rotate 90 degrees from a horizontal to a vertical position. This is because the connecting member 5 is a rectangular parallelepiped as shown in Fig. 4, but one side is filleted (corner rounded). The connecting member 5 rotates at the fillet curved surface 60, which is a curved surface, but does not rotate at the surface 61, which is a flat surface. Therefore, the main body 2 can rotate a maximum angle of 90 degrees around the straight line connecting the convex parts 58 and 59 as the central axis. That is, the connecting member is a rectangular parallelepiped with one side being filleted, so that the main body is configured to be rotatable through a maximum angle of 90 degrees.

[0025] Next, a description will be given of (2) the connection between the connecting member 5 and the first block 3 and second block 4. The connecting member 5 has a first slit portion 51 and a second slit portion 52 on both sides of a surface 61 in the AA' direction. On the other hand, the first block 3 has an insertion piece 33 at its upper end (the connecting member side). Similarly, the second block 4 has an insertion piece 43 at its upper end. The insertion piece 33 is inserted from the insertion hole 56 of the connecting member 5, and is capable of linearly sliding through the first slit portion 51 toward the center of the connecting member. Similarly, the insertion piece 43 is inserted from the insertion hole 57 of the connecting member 5, and is capable of linearly sliding through the first slit portion 52 toward the center of the connecting member.

[0026] The connecting member 5 also has a tension coil spring 53 on the inside, and hooks 54 and 55 on the tip thereof. The first block insertion piece 33 has an upper end provided with a hanging portion 34 for hanging a hook 54. Similarly, the second block insertion piece 43 has an upper end provided with a hanging portion 44 for hanging a hook 55.

[0027] As shown in FIG. 3, hooks 54 and 55 are hung on hanging portions 34 and 44, respectively. To facilitate finger passage when hanging, holes 62 and 63 are provided in shaft portion 64 of connecting member 5.

[0028] In addition, rubber may be attached to the back side of the first block 3 and the second block 4 to prevent slipping.

[0029] The magnet portion 21 of the main body 2 has two functions: fixing and storing the wheels.

[0030] 5 and 6 are diagrams showing how the present invention is used. When the wheels are fixed in the vertical position as shown in FIG. 5 and rotated 90 degrees, the magnet portion 21 of the main body 2 is attracted to the metal part of the caster by magnetic force and fixed in place. Therefore, by providing the magnet portion 21, the rotatable wheel can be firmly fixed.

[0031] When the wheel stopper 1 for a trolley is not in use, a storage method of the present invention is shown in FIG. The wheel stopper for a carriage 1 can be easily stored since it is attracted to the back plate of the carriage by the magnet part 21.

[0032] As described above, the magnet part 21 is attracted to and fixed to the metal part of the wheel by magnetic force when in use. When not in use, the wheel stopper 1 for a trolley is attracted to the back plate of the trolley, and can be easily stored. [Industrial Applicability]

[0033] The wheel stopper of the present invention can be widely used for dollies. [Explanation of symbols]
