The present invention relates to a handle height adjustment mechanism of a cart.
Handcarts, such as strollers and luggage carriers, are provided with handles to push by hand. As a rule, the handle is fixed to the body of the cart and the handle height cannot be adjusted. Therefore, a lot of inconvenience followed.
That is, the person pushing a cart may be a tall person or a short person. These people feel a lot of inconvenience because the height of the handles cannot be adjusted.
Accordingly, an object of the present invention is to provide a mechanism that can easily adjust the handle height of the cart.
The handle of the cart according to the present invention has a top rod portion having a grip and a bottom rod portion slidably supporting the top rod portion vertically. One of the upper and lower rod portions forms a sleeve and the other forms an insert suitable for receipt from one end of the sleeve. The insert is formed with a plurality of engaging holes arranged vertically. The sleeve is engaged by having a rotatably attached lever having an engaging projection that fits into the engaging hole. The lever receives a constant force by the spring so that the engaging projection rotates in a direction that fits the engaging hole.
Moreover, the stopper is rotatably attached to the sleeve so that the engaging projection does not separate from the engaging hole. The stop is provided with an urging portion having an area sufficient to cover at least a portion of the lever when in the predetermined position with respect to the lever, and extends outwardly on the rotational side of the stop and stops the urging portion and the lever to stop rotation of the stop. It has a brake in contact with the insert pressure member when covering the minimum portion.
Therefore, when the engaging projection engages one of the engaging holes, rotation of the lever is suppressed so that the engagement between the engaging projection and the engaging hole is not released.
As described above, the hand-pushing handle according to the present invention has a sleeve and an insert suitable for slidably received in the sleeve, and the engaging projection on the lever attached to the sleeve is suitable for the engaging hole formed in the insert. It can be engaged in position so that the height of the handle can be adjusted according to the height of the person pushing the cart. Moreover, since the coupling between the coupling protrusion and the coupling hole is applied so as to be maintained firmly, the coupling between the coupling protrusion and the coupling protrusion can be avoided by accidental tissue.
These and other objects, features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.
In FIG. 1, the baby carriage 1 has a handrail 2, a front leg 4 having a front wheel 3, a rear leg 6 having a rear wheel 5, and a seat support rod 7 supporting a seat. And a connecting member 8, 9, 10 for connecting the left and right members, and a handle 11 connected to the push rod, that is, the lower end of the rear leg 6. The present invention relates to a handle height adjustment mechanism.
In this embodiment, the handle 11 having the handle height adjusting mechanism provided on the left and right sides shown by reference numerals 13 and 12 is generally an inverted " U " shape (but not limited to this shape). The device 12 on the right side has the same basic arrangement as the device 13 on the left side and works the same. Therefore, description will be made using the apparatus 12 on the right side.
In FIGS. 1 and 2, the handle 11 has a top rod portion 14 and a bottom rod portion 15. The upper rod portion 14 has a grip 16 that is held by the person pushing the stroller.
Top rod portion 14 and grip 16 are secured together. Alternatively, a circular opening 17 may be formed at the upper end of the upper rod portion 14 and a circular protrusion 18 may be formed at the lower end of the grip 16. Thus, by engaging the opening 17 and the projection 18 with each other, the grip 16 can be attached to the top rod portion 14.
Furthermore, the grip 16 can be folded and supplemented to the same device as a design that allows the protrusion 18 to rotate inside the opening 17.
The lower rod portion 15 supports the upper rod portion 14 for vertical sliding motion. Furthermore, the top rod portion 14 forms a sleeve having an opening 19 therein and the bottom rod portion 15 is adapted to be slidably received in the opening 19 from one end of the top rod portion 14. Form the insert.
2 to 4, the lower rod portion 15 is formed with a plurality of coupling holes 20 arranged vertically.
The upper rod portion 14 is coupled to the engagement hole 20 by having a lever 21 rotatably attached through the pin 22. The lever 21 has an operating part 23 for rotating the lever on the upper side of the rotating shaft, and a locking part 24 on the lower side.
The locking portion 24 has a coupling protrusion 25 that fits tightly into the coupling hole 20 of the lower rod portion 15. And the lever 21 receives a constant force by the spring to rotate in the direction in which the engaging projection 25 is tightly fitted in the coupling hole (20). Kickspring 26 was used as an example. One end of the kick spring 26 is adjacent the actuating portion 23 of the lever 21 and the other end is provided with a spring seat provided on the outer surface of the lower rod portion 15 or the inner surface of the upper rod portion 14. Attached to pin 22 in a state adjacent to 27. While the other end of the kick spring 26 can be in direct contact with the lower rod portion 15, it is preferred to provide a spring seat 27 in view of the associated sliding movement between the upper and lower rod portions 14, 15. Do.
Furthermore, the upper rod portion 14 has a stop 28 which prevents the engagement between the engaging projection 25 on the lever 21 and the engaging hole of the lower rod portion 15 being released. It is attached to the lower rod portion rotatably through the same pin 22 used when attaching to the lever 21.
The stop 28 shown in FIG. 3 has a pressing portion 29 and a braking portion 30. The pressing portion 29 has an area sufficient to cover the minimum portion of the lever 21 when the stop 28 is in a predetermined position with respect to the lever 21. In particular, the lever 21 rotates until its engaging projection 25 engages with the engaging hole 20 of the lower rod portion 15, and the stop 28 is in the predetermined direction (in this embodiment, the lever ( In the direction of rotation 21), the pressing portion 29 of the stop 28 approaches its upper surface to cover the locking portion 24 of the lever 21. Furthermore, the braking part 30 is formed to extend outward of the rotation axis of the stop 28. In the figure, since the positional relationship between the brake unit 30, the lever 21 and the upper rod portion 14 is difficult to understand, it will be described in detail. First, the braking part 30, that is, the stop 28 is located adjacent to the inner side of the upper rod portion 14, and the lever 21 is located adjacent to the inner side of the braking part 30. 28 and the lever 21 are in the predetermined position, that is, the engaging projection 25 and the engagement by rotation on the stop 28 until the pressing portion 29 covers the locking portion 24 of the lever 21. When the hole 20 is engaged, the braking portion 30 comes into contact with the abutment surface of the lower rod portion 15 to stop the rotation of the stopper 20. Therefore, the stopper arrow 28 in FIG. Rotation in the direction of (A) requires some force.
The steps shown in FIG. 4 will be described in more detail.
Prior to this step the top rod portion 14 slides along the bottom rod portion 15 to a suitable position to provide a suitable handle height. Due to the engagement between the engaging projection 25 on the lever 21 and the engaging hole 20 of the lower rod portion 15 in this position, the sliding movement is suppressed so that the height of the handle is fixed.
As described above, since the lever 21 receives a constant force by the action of the kick spring 26 to rotate in the direction of the arrow B, the engagement between the engaging projection 25 and the engaging hole 20 is maintained firmly. . However, if the person pushing the stroller accidentally touches the operation part 23 of the stop 28, the coupling between the coupling protrusion 25 and the coupling hole 20 is released. Therefore, it is preferable that the coupling between the coupling protrusion 25 and the coupling hole 20 is not easily released. The stop 28 serves for this purpose. The stop 28 of the step shown in FIG. 4 has a braking portion 30 in contact with the lower rod portion 15, so that rotation in the direction of the arrow A is suppressed. At this time, since the pressing portion 29 of the stop 28 covers the upper side surface of the locking portion 24 of the lever 21, the rotational movement of the lever 21 in the direction of the arrow A is also suppressed. The lever 21 is in this way subjected to upward force by the kick spring 26 and pressed downward by the stop 28 so that the engagement between the engaging projection 25 and the engaging hole 20 is more firmly maintained.
5 shows a step in which the engaging projection 25 and the engaging hole 20 are separated from each other. In FIG. 4 and FIG. 5, the operation which is converted from the step shown in FIG. 4 to the step shown in FIG. First, the stop 28 is organized with a force greater than a predetermined force in order to rotate in the direction of the arrow A. FIG. When the stopper 28 is rotated so that a pressing action of the stopper 28 of the stopper 28 is eliminated, the lever 21 is rotated by the operating part 23. That is, as shown in FIG. 5, the engagement between the engaging projection 25 and the engaging hole 20 can be released by pressing the actuating part 23 so that the locking part 24 rotates in the direction of the arrow A. FIG. have. Moreover, in rotating the lever 21 the actuating portion 23 of the lever 21 is pressed directly by hand but may be pressed through the stop 28. That is, the stop 28 is operated to rotate in the direction of the arrow A and this rotational operation continues even until the stop 28 contacts the actuating portion 23 of the lever 21. ) Rotates by the pressing force by the stop 28. This operation is simple and very convenient.
Considering a simple operation, it is preferable to release the engagement between the engaging projection 25 and the engaging hole 20 by strongly pressing the operating portion 23 of the lever 21 without touching the stop 28 by hand. In this case, the pressing force applied to the actuating part 23 should be large enough to overcome the braking force applied by the stop 28.
In the step shown in FIG. 5, the top rod portion 14 is allowed to slide the bottom rod portion 15. Therefore, to adjust the height of the handle, the upper rod portion 14 slides to a predetermined position with the lever 21 held in the step shown in FIG. And when the pressing force applied to the lever 21 is removed, the lever 21 is automatically rotated by the action of the kick spring 26, whereby the engaging projection is engaged with the engaging hole (20). The stop 28 then rotates in the direction of the arrow B to secure the engagement. The height of the handle is easily adjusted in this way.
The height adjusting device of the handle described with reference to FIGS. 1 to 5 is an embodiment of the present invention shown by way of example. Therefore, various changes and modifications are possible. Typical modifications are described below.
First, attention should be paid to the attachment position of the stop 28.
In the above embodiment, the axis of rotation of the stop 28 coincides with the axis of rotation of the lever 21. However, the arrangement shown in the embodiment has the following advantages, that is, the single pin 22 is sufficient to rotatably support the lever 21 and the stop 28 and the lever 21 and the stop 28 are The structure of the handle height adjusting device becomes more compact since it can be installed in the same position, and furthermore, the coupling between the engaging projection 25 and the engaging hole is simple because the stop 28 and the lever 21 rotate in the same direction. The rotational operation is very simple because it can be released easily, but these axes do not always have to coincide and the stop 28 and the lever 21 can be installed in separate positions.
In the embodiment it is shown that the pressing portion 29 of the stop 28 has a sufficient area to cover the entirety of the locking portion 24 of the lever 21. However, in view of the function of the pressing portion, it will be understood that the pressing portion 29 is sufficient to have an area covering the minimum locking portion 24. However, if the pressing portion 29 has an actual length, it is easy to confirm whether the stop 28 is in the stage shown in FIG. 4 or in the stage shown in FIG. Checking the position of the stop 28 is equivalent to checking whether or not the engaging projection 28 and the engaging hole 20 is engaged.
In the above embodiment, the top rod 14 forms a sleeve, and the bottom rod portion 15 forms an insert suitable for receiving one end thereof in the sleeve. However, this arrangement can be reversed. That is, the lower rod part 15 may form a sleeve, and the upper rod part 14 may form an insert.
Moreover, the stroller is shown as an example of a cart to which the present invention is applied. However, the shape of the baby carriage is not limited to the illustrated example. For example, the stroller may be in a form that allows the grip 16 to be folded as described above. Moreover, carts are not limited to strollers and include shopping carts and luggage carriers.
Although the subject matter has been shown and described in detail, various changes and modifications are possible without departing from the scope of the invention as defined in the appended claims.
