Description

When traveling on a bus, train, etc. with a large suitcase with four wheels during travel, a stand for brakes is provided to prevent the suitcase from moving unexpectedly due to the acceleration of the vehicle or centrifugal force.

Conventionally, there is a device for preventing the suitcase from rolling.
The brake structure is made so that the wheels of the casters do not roll as disclosed in JP-A-2007-331561.
The original large suitcase has four casters for movement. I often see the idea of putting a brake on this caster to prevent rolling,
There are the following disadvantages.
(1) The structure is complex and tends to be expensive.
(2) The wheels of casters were originally designed to roll and are not as a brake. In other words, since the ground contact area is small, and the caster is mainly intended for rolling on the ground contact surface, the caster is designed mainly for durability and is difficult to make with a material that has an effect as a brake.

An object of the present invention is to provide a rolling prevention stand in order to prevent the travel suitcase from moving unexpectedly.

In order to improve the above, we considered attaching a stand for braking to the suitcase separately from the casters. That is, apart from the wheels, the brake rod is attached to the suitcase so that it can slide up and down.
Always keep it safe to move, and when you get on the train, lower the stand for the brake and fix it to the main body with screws, and fix the suitcase to the floor.
The tip of the bar should use a material such as rubber to increase friction with the floor and to prevent damage to the floor. Further, it is preferable to provide a certain area for the ground contact area. It is also possible to lift the brake stand with a spring so that the stand does not touch the ground carelessly. On the contrary, the brake stand is urged by a spring or the like to press the floor with a certain pressure.

Compared with the case where the wheels of rolling casters are not turned, the effect as a brake is great, and the stability against the acceleration on the curve is great when getting on a train or the like. Moreover, since the structure is simple, it is difficult to break down and the manufacturing cost is attractive.

Put out a stand to prevent rolling in the suitcase. This stand can also be stowed in, and when used as a rolling prevention, it should be in contact with the floor.
The stand tip is made of a soft material such as rubber with a certain area so that it has an appropriate braking force and at the same time prevents damage to the floor.
This stand may be increased by one or more. 4 is the best, but 2 is quite effective.

In addition, the structure for retracting and taking out the stand may be constituted by one stand or by several. It is a manual lever that performs this operation, but by checking its position, it is possible to grasp at a glance whether the suitcase is currently braked or whether it can move freely. The lever cover member is recessed with respect to the position of the lever, and the lever is moored and locked so that the brake is not inadvertently applied or released.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a stand for preventing the travel carry bag of the present invention from moving. A groove 5 is opened in a carry bag with wheels, and the knob 3 can be moved up and down. The stand for preventing movement is 2, and the lower part is made of a material that has a lot of friction made of rubber 4 or the like and that is less likely to damage the floor surface. The upper part of the spring 6 is fixed to the suitcase, and the lower part of the spring 6 suspends the stand 2. The spring 6 ensures that the stand is not out of the suitcase in the free state, thus ensuring safety.

FIG. 1-A shows a state in which the stand is stored, and FIG. 1-B shows a state in which the movement preventing bar is lowered to a predetermined position. There is also a screw hole in the state where the knob 3 is raised, so that it can be fixed by turning the knob, or after the stand is moved down by the knob 3, it can be fixed by turning the knob. Is good.
FIG. 2 shows an embodiment. There is a box outside the suitcase, and a stand 2 and a spring are housed in the box (not shown). Also, the stand is lowered by the knob 3, and the knob is turned and stopped at a predetermined position.

FIG. 3 is a modification of FIG. In FIG. 3, the slot 17 is formed in a letter “J” so that the movement preventing rod does not easily go up. The stand is suspended by a spring inside the box, so the knob is stable at the tip of the J-shape.
FIG. 4 shows this embodiment. A box is made outside the suitcase, and a stand and a spring are stored in it. In FIG. 4, for the sake of clarity, the operation knob and the hanging spring inside the box are omitted.

FIG. 5 shows the embodiment of FIG. Pull the stand to prevent it from moving out of the suitcase so that it does not come out of the suitcase.If you do not want the suitcase to move inadvertently, lower the lever and place the stand to prevent it from moving. Go outside. The spring 26 is set to push the stand out with a strong force, and the force is picked up by the wire 28. Even when the suitcase is full of luggage, it pushes with a strong force so that the wheels do not touch.

FIG. 5 shows a picture in which the wire is outside the suitcase, but a protective cover may be attached as shown in FIG. FIG. 7 shows a lever portion from the opposite side of FIG. 6, but the operation lever 29 is covered with a cover 35, and a mooring stop 36 is provided on the cover. Is good. Moreover, you may incorporate in a suitcase. Further, the wire may not be exposed, but may be configured such that a wire is covered with a vinyl pipe and the roller is omitted. This vinyl pipe is called an outer casing in a bicycle member, and is flexible and functions to transmit the operation force of the wire inside to the brake pad. It is also possible to put some grease inside to improve the sliding of the wire. Although FIG. 1 and FIG. 3 demonstrated that a hole was made in a suitcase, it is good also not to make a hole directly in a suitcase, but to put these apparatuses in another box, and to attach to the inside or outside of a suitcase. 2, 4, and 6 are examples of this.

There is also a way to reverse the operation. The spring of FIG. 5 needs to push down the stand by the spring 26 with a force that does not lose its weight even when the suitcase is full of luggage. Otherwise, the weight of the load will be lost and the caster will touch the ground and will not serve as a non-slip stand. For this reason, the spring requires a considerably strong force. For this reason, when the stunt is stored, the lever 29 must be operated with a considerably large force. In order to overcome this force, the ratchet prototype is shown in FIG. 9, but it is also possible to reduce the diameter of the winding portion and use the ratchet to pull it up little by little with the lever. Of course, in some way, the ratchet can be released.

Further, since the spring pushes the stand with a strong force as shown in FIG. 8, it is preferable to provide a stand stopper 39 to prevent the stand 22 from coming out abnormally excessively even when the luggage of the suitcase is light.

FIG. 10 shows the concept of reversal of FIG. In other words, when the wire 28 is pulled by the operation lever 29, the stand 22 comes out outside as shown in FIG. This way, you don't have to use a big spring. That is, the pulling force of the lever is reversed by the roller 38, and the force is brought in the direction of pushing down the stand 22. Of course, the tip of the wire is attached to the top of the stand 22.

11-13 is explanatory drawing about the invention which rotates a stand and puts it under a suitcase.
FIG. 11 shows a combination of a lever and a spring but is set to prevent rolling. It is a drawing when 45 is stepped on with a foot and the suitcase is pulled up by hand to put it under the suitcase while raising a stand for preventing rolling. Reference numeral 44 denotes a spring. When the stand is to be lifted, the pattern can be automatically stored with the force of the spring by slightly lifting the suitcase.

I would like you to pay attention to the angles of 43 and 46. It is a requirement that this angle be an acute angle smaller than 90 degrees. In this way, a stable situation can be achieved due to the weight of the suitcase, and a structure can be constructed in which the stand cannot be easily removed without lifting the suitcase. A simple structure can realize stable rolling prevention. In addition, this configuration with an acute angle is 43, 44, 46, and even if only one side of the suitcase is effective, it is made on the front and back two sides of the suitcase, and it is connected to 45, 47 as described above. It is also good to do.

FIG. 12 is a detailed view of the stand. 43 and 46 are integral parts, and are lifted by a spring 44. When storing, when the suitcase is lifted, it automatically moves upward as indicated by the broken line by the force of the spring. The angle formed by 43 and 46 must be an acute angle. By making an acute angle of about 45 °, stable slip prevention can be realized by the weight of the suitcase.

FIG. 13 is also a detailed view. A joint is provided in 47 so that the opening 48 of the suitcase does not interfere. 49 is a stick for stepping on with a foot, and its volume is slightly expanded for easy stepping.

FIG. 14 and FIG. 15 show the structure of the rolling prevention stand that brings the stand under the suitcase by rotation made of a combination of a bar and a spring. It is an application of a bicycle stand.
53 has a stand, and 54 has a hooking claw 55 for fixing the position of the stand 53 when it is stood. When releasing, this 54 is kicked with a foot, and the stand 53 is rotated left and released. As shown in FIG. 15, it is smart to store the machine directly next to it. Although this stand is effective even if it is a single unit, it may be formed with a configuration without 54, 55 on the other side of the suitcase to realize a more stable stand. Another set may be provided. 54 and 55 are connected and move as a unit.

A claw 58 in FIG. 15 indicates the position of the bent metal fitting 54. When 54 is kicked back with the foot and the claw of the 55 claw is released, the claw 58 integrated with the 54 moves the 53, and the spring force in the 54 further causes the 53 to be caused by this metal fitting. Keep it in a horizontal position.

In the case of setting in reverse, simply by kicking 53, 54 moves by the claw 58, and finally 53 is moved vertically by the force of the spring 57 and is locked by the claw 55.
A metal fitting 59 is provided with a recess for hooking the lock claw 55 and is fixed to the suitcase.

Since it is a stand that can be used as an instrument for preventing unexpected movement of a suitcase used for travel, it can be applied to various suitcases.
