Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an improvement of a carry bag provided with a puller on a bag that can be moved by casters, and more specifically, a rod-like puller for pulling can be put in and out of a storage portion on the bottom of the bag. When the puller is used by pulling it out from the storage part, the bag can be pulled or pushed by the puller, and when the puller is pulled out, the puller itself falls down in the horizontal direction. The present invention relates to a carry bag that can be safely used by keeping a stable posture in the vertical direction even when it is always rotated upward by a spring force and the hand is released.

[0002]

2. Description of the Related Art Conventionally, a carry bag provided with a puller in a bag that can be moved by casters has been known, but most pullers in conventional carry bags use a string. As a material other than a string, a bar-shaped puller having a short length and attached to the upper portion of the side surface of the bag via a hinge is known to be downward. With this hook-shaped puller attached to the upper side of the bag, the base end of the bar is hinged to the upper part of the bag so that the handle falls down in order to store the puller in the bag conveniently. It is configured to be attached to the shaft, and when used, it is taken out from the bag so that the handle located below rotates around the hinge upward.

[0003]

A bag movable by a caster is pulled by a puller to move the bag.
You can move easily. However, in the conventional bag of this type, which uses a string as a puller, the bag can be pulled and moved by the string, but cannot be pushed and moved. In addition, the T-shaped puller stored in the upper part of the side surface of the bag has the base end of the puller connected to the upper part of the bag. Instead of pulling the part, you will pull the upper part. Therefore, when the caster on the bottom hits an obstacle during towing, the upper part of the bag will be pulled by the puller before the caster gets over the obstacle, causing the bag to fall easily. ing. In addition, in the structure in which the puller is provided on the side surface of the bag as described above, there is a problem in the storage form of the puller when the puller is not used, and the puller is easily detached from the storage portion. .

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the conventional carry bag with puller, and the puller can be stored horizontally in a storage portion provided at the bottom of the bottom of the bag. When the hand is pulled out from the storage part, the puller pivots upward by the force of the spring to make it easier to hold the puller, and the lower part of the puller is automatically rotatable to the outlet of the storage part. You can pull or push the bag with the puller, and when the puller is pulled out, the puller rotates upward due to the force of the spring. It is an object of the present invention to provide a carry bag in which the puller automatically stands up in the vertical direction even when the hand is released from the puller and does not obstruct the passage around the bag.

As a concrete means for this purpose, the present invention includes a pair of rails provided in a storage portion at the bottom of the bag, a pair of left and right movable cases slidably arranged inside these rails, and a side surface on one side of the bag. And a rod-shaped puller having a rear end portion inserted from the opening portion along the rail into the storage portion, and a rear end portion of the puller with respect to a base shaft erected between the movable cases, The pull tab is connected by winding a spring for rotating in the vertical direction about the base axis, and the movable case is attached to the movable case when the pull tab rotates in the vertical direction about the base axis. A lock means for engaging the rail with the rail, further comprising a sleeve parallel to the rail on the base shaft, and an actuating shaft having a bendable connecting portion inserted in the sleeve, At the rear end of the operating shaft, the opening Part vicinity of engaging a hook provided on the bag bottom, is characterized in that the pull tab rear part and a stopper for fixing in the opening.

[0006]

In the carry bag according to the present invention, the puller is normally pushed horizontally along the rail from the opening on the side surface of one side of the bag into the storage portion on the bottom surface of the bag. Since the pull tab is rotatably mounted around a base shaft that is hung between movable cases whose rear ends move along rails, the pull tab is rotatably attached by the spring. Elasticity is imparted so that it can rotate upward. However, when the puller is stored in the storage portion in a horizontal state, the bendable connecting portion of the operating shaft, which is inserted into the sleeve on the base shaft at the rear end of the puller, is located in the sleeve. As a result, the actuating shaft maintains a straight state in which it does not bend, so that the puller holds a horizontal posture and is kept inside the storage portion along the rail regardless of the upward turning force applied by the spring. It is stored without any problem.

When the bag is towed by the puller, if the tip of the puller is pulled out horizontally from the opening along the rail, the rear end of the puller is pulled out to the outside of the bag opening. A stopper provided on the base shaft of the rear end of the puller engages with a hook near the opening to prevent the rear end of the puller from coming out of the opening. When the puller is pulled further outward in this state, the operating shaft inserted into the sleeve on the base shaft at the rear end of the puller is pulled, and the bendable connecting portion of the operating shaft is pulled out of the sleeve. And the connecting portion is in a bendable state. Therefore, the pull tab to which elasticity is applied so as to always rotate upward by the spring force rotates upward around the base shaft,
The pull-out handle will be stably held vertically.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure of a carry bag according to the present invention will be described with reference to the illustrated embodiment. FIG. 1 is a perspective view showing the structure of a puller storage portion 3 provided on the bottom surface 2 of the bag 1. . The storage portion 3 is for storing the pull tab 6 provided in the bag 1, and is provided on the lower surface of the inner bottom 5 of the bag 1 having the casters 4 on the bottom surface 2 as shown in FIG. There is. An opening 7 for pulling in and out of the puller 6 is provided on one side surface of the bag in which the storage 3 is located, and a pair of groove-shaped rails 8 are provided on the bottom surface 2 located at the back of the opening 7. It is fixed, and between the rails 8, the pull tab 6 consisting of a pair of parallel rods 9 is horizontally arranged.

Each of the pull tabs 6 is constructed such that each rod 9 is expandable and contractable at an intermediate portion, and the length of the pull tabs when the pull tabs 6 are contracted is contained in the storage portion 3, and the handle 10 at the tip is the opening portion 7.
It is designed to be located inside the part where it is easy to remove. When the handle 10 located in the opening 7 is held and the puller 6 is pulled out horizontally from the outside of the opening 7, each rod 9 extends to a predetermined length.

Inside the rails 8, the rails 8 are
A pair of movable cases 11 that move along the inside of the groove are arranged, and a rail 8 is provided between the front ends of the movable cases 11.
A base shaft 12 in a direction orthogonal to the
The bearings 13 are rotatably installed so as to be inserted into the rear end of the rods 9 and fixed to the rear ends of the rods 9 of the puller 6, and are fitted to both end portions of the base shaft 12. The end is rotatably connected to the base shaft 12. In addition, coil springs 16 are wound around inner portions of the bearing 13 at both ends of the base shaft 12, respectively.
A base shaft with both ends of 16 installed between the rear ends of the puller rods 9.
By engaging a horizontal rod 14 parallel to 12 and a similar intermediate horizontal rod 15 installed between the movable cases 11 respectively, the puller 6 has the spring 16 with the base 12 as a center. An upward turning force is given by elasticity.

Further, the springs at both ends of the base shaft 12 are
Bearings 17 are fitted on the outer circumference of the base shaft 12 inside the inner part of the shaft 16, and between the bearings 17 and the horizontal rod 14 installed between the rear ends of the puller rods 9. The front sleeves 18 are fixed in a direction parallel to the rails 8, respectively, and the intermediate section horizontal rods 15 provided between the movable cases 11 are provided.
Also, rear sleeves 19 are fixed respectively on the same row corresponding to the front sleeve 18, and operating shafts 20 are slidably inserted into the corresponding front and rear sleeves 18 and 19, respectively. As shown in FIG. 8, the actuating shaft 20 is provided with a bendable connecting portion 21 in the middle portion between the front and rear sleeves 18 and 19, and the puller 6 is placed horizontally in the storage portion 3 as shown in FIG. When it is stored in, the connecting portion 21 is located inside the front sleeve 18, and is kept straight by the connecting portion 21 without being bent.

At the rear ends of the both operating shafts 20, the both operating shafts 20
A horizontal rod-like stopper installed so as to connect the rear ends of the
23 is provided, and both ends of this stopper 23 are springs 24.
By means of the movable rod 11 and the intermediate rod
It is connected to 15, and both actuating shafts 20 are always attracted toward the rear sleeve 19 by the force of the spring 24. Further, a hook 22 is fixed on the bottom surface 2 between the rails 8 near the opening 7 in the storage portion 3, and as shown in FIG. When pulled out, the stopper 23 engages with the hook 22 and stops the rear end of the puller 6 so that it is not completely separated from the opening 7.

As described above, when the stopper 23 engages with the hook 22 on the bottom surface 2 of the storage portion, the rear end portion of the pull tab 6 stops moving near the opening portion 7. As shown, in that position, the operating shaft 20 connecting portion 21 is still located inside the front sleeve 18, and the operating shaft 20 maintains the linear state. Therefore, in this state, the puller 6 is wound around the base shaft 12. The force of the spring 16 does not rotate upward. Therefore, when the puller 6 is pulled further forward as shown in FIG. 9 from the state where the stopper 23 is engaged with the hook 22 on the bottom surface 2 of the storage portion, the stopper 23 of the operating shaft 20 is hooked.
Since it is still engaged with the handle 22, only the pull tab 6 moves forward, so that the bendable connecting portion 21 of the actuating shaft 20 comes out of the front sleeve 18 rearward.

When the connecting portion 21 of the operating shaft 20 is exposed to the rear of the front sleeve 18 in this manner, the operating shaft 20 is connected to the connecting portion 21.
The state becomes bendable. In this state,
As described above, the connecting portion 21 of the actuating shaft 20 is positioned in the front sleeve 18 to maintain the actuating shaft 20 in a straight state, thereby preventing the pulling force of the puller 6 from being rotated upward by the spring 16. The moment the pulling handle 6 is rotated upward by the force of the spring 16 to a vertical state as shown in FIGS. It bends at the connecting portion 21 and follows the upward rotation of the pull tab 6 about the base shaft 12.

When the pull tab 6 is completely pulled out of the opening 7, the pull tab 6 rotates upward due to the elasticity of the spring 16, and the elasticity of the spring 16 causes the pull tab 6 to move vertically from the horizontal position. Since it extends over an angle range of almost 90 degrees, the bag 1 can be easily towed by the puller 6 which is always given an upward force, and when the user stops and releases the puller 6, the puller 6 Can be automatically maintained in a vertical standing state by the force of the spring 16.

As described above, since the stopper 23 is engaged with the hook 22 of the storage portion 3 at the rear end of the pull tab 6 when the pull tab 6 is pulled out to the outside of the opening 7, When pulling the bag 1 with the pull tab 6, the pull tab 6 is not likely to come out of the opening portion 7. However, when the bag 1 is pushed and moved as opposed to pulling the bag 1 by the pull tab 6, The stopper 23 is disengaged from the hook 22, and the pull tab 6 is pushed back into the storage section 3. Therefore, as shown in FIGS. 6 and 7, the movable case 11 for guiding the rear end of the pull tab 6 along the rail 8 is provided when the movable case 11 is stopped at a position close to the opening 7. ,
Locking means for fixing the movable case 11 to the rail 8 is provided.

The locking means of the movable case 11 is a lever 26 rotatably attached to the movable case 11 by a shaft 25.
And a protrusion 27 protruding upward from the rear end of the lever 26.
And a hole 28 formed in the upper surface of the rail 8 at a position close to the opening 7 so that the protrusion 27 is engaged. Further, a curved window hole 29 is formed inside the front end portion of the movable case 11 along the periphery of the base shaft 12, and a pin provided on the outer periphery of the bearing 13 at the rear end of the puller rod 9.
The pin 30 and the front end of the lever 26 are configured to engage with each other when the pin 30 is inserted into the window hole 29. The front end of the lever 26 is always pushed downward by a spring 31 wound around the shaft 25.

As shown in FIG. 1, when the pull tab 6 is stored in the storage portion 3 in a horizontal state, the pin 30 on the outer periphery of the bearing 13 is located above the window hole 29 as shown in FIG. Since the pin 30 is rotated, the front end of the lever 26 is pushed up by the pin 30, and the projection 27 at the rear end of the lever 26 is lowered below the inside of the movable case 11. Further, when the pull tab 6 is pulled out to the outside of the opening 7 and rotated upward as shown in FIG. 10, the pin 30 on the outer circumference of the bearing 13 is located below the window hole 29 as shown in FIG. Since the lever 26 is pivoted to the upper side, the rear end of the lever 26 is pivoted upward by the elasticity of the spring 31, and the protrusion 27 passes through the hole 32 formed in the upper surface of the rear end of the movable case 11 so that the hole 28 of the rail 8 moves.
And the movable case 11 is fixed to the rail 8. The state in which the protrusion 27 is engaged with the hole 28 of the rail 8 cannot be removed unless the pull tab 6 is rotated to the horizontal position, so that the pull tab 6 is held at an appropriate inclination angle from the horizontal position to the vertical position. However, even if the bag 1 is moved so as to be pushed, the movable case 11 is not pushed back into the storage section 3.

[0019]

[Effect] As described above, the carry bag according to the present invention can be stored horizontally in the storage portion on the bottom of the bag, so that when the pull tab is not used, the pull tab is completely stored in the bag. You can carry the bag with. Also, when using the bag by pulling it out of the storage part, by pulling the puller out of the storage part in a horizontal state, the puller can be extended to a predetermined length and automatically rotated upward by a spring. Hold the height position that is easy to hold. In addition, in this state, since the pulling bag itself is not subjected to a force that pushes down the pulling bag itself due to the load of the bag, the pulling operation can be performed very easily.

Further, since the pull tab projects forward from the lower portion of the bottom surface of the bag, even if the caster on the bottom surface hits an obstacle when the bag is towed, the lower portion of the bag can be stably pulled by the pull finger. Even with a heavy-duty bag, the casters can safely pass over obstacles without fear of falling. Further, the rear end of the puller is fixed in the pulling direction and the pushing direction by the hook and the stopper engaging the front of the storage part and the locking action of the movable case on the rail, so that the bag by the puller is fixed. Not only the pulling movement but also the pushing movement can be performed without any hindrance, and even if the puller is released when the movement is stopped, the puller automatically rotates upward, so the puller falls forward. There is an advantage that it can be handled easily during movement without having to do so.
