Description

Technical Field

[0001] The utility model relates to the field of umbrella production and manufacturing, in particular to an umbrella handle mechanism for an automatic umbrella. Background Art

[0002] Among existing umbrellas, automatic opening and closing umbrellas are popular among consumers due to their convenience. The umbrella can be opened and closed by pressing a button set on the umbrella handle. The umbrella is automatically opened and closed by using a compression spring installed inside and a clamping head set on the button.

[0003] In automatic opening and closing umbrellas, due to the high elastic force of the internal compression spring, the button and the clamping head must be tightly fitted together to achieve an explosion-proof effect. However, this also brings the problem of high pressing force when opening the umbrella, which is inconvenient for women or users with less strength. To this end, some automatic umbrella developers have reduced the contact area between the button and the clamping head, significantly reducing the operating force required to press the button, and even enabling one-handed operation. However, this method actually increases the risk of opening the umbrella due to accidental operation. Because the button is located on the outer wall of the handle and has a low operating force, it is more sensitive. The umbrella can be opened by a slight external touch. Due to the action of the compression spring, the umbrella opens instantly, which can easily cause accidental injury. For example, a woman who stores an automatic opening and closing folding sun umbrella (sun protection) in her bag may cause the button and the clamping head to disengage from the restraint. When she takes out the umbrella, before she can adjust it to face the unmanned area, it will open instantly. The high-pressure compression spring can easily cause the umbrella shaft or umbrella end to be ejected, which can easily cause accidental injury or damage other items.

[0004] In summary, the handle of the existing automatic umbrella needs to be further improved. Utility Model Content

[0005] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide an umbrella handle mechanism for an automatic umbrella, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problem that the existing automatic opening and closing umbrellas are easily opened by accident and the elastic force generated during the instant opening may cause damage to people or objects.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A handle mechanism for an automatic umbrella, which drives a button to move radially along the handle to open or close the umbrella; the handle mechanism includes a housing, a movable cover, an elastic member, and a reversing structure;

[0008] The housing is open at one end and forms a receiving cavity for the handle with buttons to be installed;

[0009] A movable cover is sleeved on one end of the housing having an opening and is movable along the axis of the housing; the movable cover is positionally connected to the inner wall of the housing or the handle via a limiting structure;

[0010] an elastic member, one end of which abuts against the inside of the movable cover and the other end of which acts on the handle or the end of the housing;

[0011] The reversing structure is formed or installed in the movable cover and placed between the inner wall of the shell and the outer wall of the handle; the reversing structure moves axially along the handle with the movable cover and acts directly or indirectly on the button of the handle to push the button to move radially along the handle.

[0012] Furthermore, the limiting structure includes a protrusion and a travel guide groove; the protrusion is formed on the outer wall surface of the handle; the travel guide groove is formed on the hanging ear of the movable cover and is opened along the axial direction of the handle; wherein, the travel guide groove is buckled into the protrusion to limit the axial linear displacement of the movable cover along the handle.

[0013] Furthermore, the reversing structure includes an extension portion and a connecting rod formed inside the movable cover; both ends of the connecting rod are hinged to the extension portion and the button respectively, and the connecting rod is arranged at a certain angle to the extension portion and the button respectively.

[0014] Furthermore, the intersection line of the connecting rod and the movement direction of the key is set at an obtuse angle.

[0015] Furthermore, the shell includes a shell and a base, the shell is provided with the accommodating cavity for installing the handle and the reversing structure; the base is fixedly installed at one end of the shell away from the movable cover for fixing the handle and the umbrella opening mechanism in the handle.

[0016] Furthermore, it also includes an anti-slip sleeve, which is sleeved on the outer peripheral wall of the shell and / or the base.

[0017] Furthermore, an annular arc portion is formed on the axial end surface of the movable cover, which is used for hooking and pulling the movable cover by hand to axially displace it toward the base.

[0018] Furthermore, an inner recessed portion for easy gripping is formed on the outer peripheral wall of the shell.

[0019] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention provides an umbrella handle mechanism for an automatic umbrella, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problem that the existing automatic opening and closing umbrellas are easily opened by accident, and the elastic force generated when opening instantly causes damage to people or objects; the present invention adopts an umbrella handle mechanism composed of a movable cover, an elastic member and a reversing structure, breaking the restriction of the traditional umbrella handle directly pushing the button to radially open the umbrella body, changing the opening direction into an axial movement, and then converting it into a radial displacement of the button. This arrangement greatly reduces the probability and risk of the button being accidentally touched (the movable cover is arranged axially between the outer shell and the umbrella body, and it is generally difficult to touch the outer end of the outer shell or the umbrella body when touched by external force), and also expands the operating area; more importantly, the comfort when pressing with fingers is better. In actual use, the palm of the hand holds the umbrella handle, and the fingers press the end surface of the movable cover and pull it toward the inside of the handle. At this time, it is the same as the movement direction of the finger joints. In this way, pulling the movable cover is more comfortable. Compared with the traditional radial pressing method, the thumb has a small space for movement, and it has to overcome the resistance of the spring inside the button. The present invention has the function of preventing accidental touches, small operating force and easy single-handed operation.

[0021] (2) The limiting structure of the present invention not only ensures that the movable cover will not fall out of the housing or the handle in the axial direction, but also ensures that the movable cover can move linearly as a whole in the axial direction, thereby ensuring that the reversing structure can push and pull the key smoothly when acting on the key, thereby preventing jamming and failure.

[0022] (3) The reversing structure of the present invention adopts a two-stage drive structure, and the reversing structure formed by the extension part and the connecting rod ensures that even if a large external force is applied, it will not directly act on the button (that is, the button will not be triggered instantly), and the force is transmitted through the connecting rod with little effort, thereby ensuring safety and providing a better operating experience.

[0023] (4) In the present invention, the movement direction of the connecting rod and the key is set at an obtuse angle, so that the movable cover can smoothly drive the key to move when it moves downward.

[0024] (5) The present invention is also provided with an anti-slip cover to prevent slipping due to sweat or an umbrella when the hand is grasping, thereby improving the support capacity of the palm after grasping, cooperating with the fingers pulling the movable cover to facilitate the application of force. In addition, the annular arc portion is also provided on the movable cover to facilitate the operation of the movable cover displacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See also Figure 1-5 The umbrella handle mechanism for an automatic umbrella described in the present invention is generally used on an automatically opening and closing umbrella, especially an automatically opening and closing folding umbrella (umbrella or parasol). By pressing the button 1 with the hand, the button moves radially along the handle, and the spring, pull wire, bullet head, etc. inside the handle cooperate to form the umbrella opening or closing (this is a prior art and will not be described in detail);

[0037] The umbrella handle mechanism of the present invention can be installed on the outer periphery of the handle 2, and simultaneously change the operating direction of the hand and the trigger button 1 to prevent the umbrella from being accidentally triggered to open due to external force;

[0038] The umbrella handle mechanism of the present invention comprises a housing 3, a movable cover 4, an elastic member 5 and a reversing structure 6;

[0039] The housing 3 is open at one end and forms a receiving cavity 30 for the handle 2 with the button 1. The housing 3 includes a shell 31 and a base 32, both of which are respectively formed by injection molding. The shell 31 is hollowed out to form a receiving cavity 30 for the handle 2 and the reversing structure 6 to be installed. The base 32 is fixedly mounted on the end of the shell 31 away from the movable cover 4 to fix the umbrella opening mechanism in the handle 2 (the umbrella opening mechanism here is the existing technology).

[0040] Moreover, the present invention has a recessed groove 311 formed on the outer peripheral wall of the shell 31, into which the anti-slip cover 7 can be inserted, and the anti-slip cover 7 can be fixed in this position to prevent the umbrella handle and the palm from slipping when holding the umbrella. In addition, an inner recessed portion 8 is formed on the outer peripheral wall of the shell 3 for easy holding.

[0041] The movable cover 4 is sleeved on one end of the shell 3 with an opening and can be limited and movable along the axis of the shell 3; the movable cover 4 is limitedly mounted on the inner wall of the shell 3 or the handle 2 through a limiting structure; it should be noted that the movable cover 4 of the present invention is in the shape of a cap, its interior is hollow, and it is covered on an open end of the shell 31; the inner surface of the movable cover 4 extends outward to form two hanging ears 41 with travel limiting grooves 411 and an extension 61 of the reversing structure 6, and the hanging ears 41 and the extension 61 are set at a certain angle, and it is best that the two are set at a perpendicular angle to each other; in addition, an inwardly concave annular arc portion 40 is formed on the outer end surface of the movable cover 4, which is convenient for the hand to hook and pull the movable cover 4 to move toward the base 32.

[0042] The elastic member 5 has one end against the inside of the movable cover 4 and the other end acting on the end of the handle 2 or the housing 3. The present invention uses a spring as an example, but it can also be other elastic components that can drive the movable cover 4 to reset.

[0043] A reversing structure 6 is formed or installed within the movable cover 4 and is positioned between the inner wall of the housing 3 and the outer wall of the handle 2. The reversing structure 6 moves axially along the handle 2 with the movable cover 4 and directly or indirectly acts on the button 1 of the handle 2 to push the button 1 to move radially along the handle 2.

[0044] The present invention is illustrated by the reversing structure 6 of the button 1 that indirectly acts on the handle 2, which includes an extension portion 61 and a connecting rod 62 formed inside the movable cover 4; a hinge hole 611 is formed on the extension portion 61, and one end of the connecting rod 62 is rotated into and passes through the hinge hole 611 through the pin A, so that the connecting rod 62 can be rotatably attached relative to the extension portion 61; and the other end of the connecting rod 62 is installed on the outer surface of the button 1, and the connecting rod 62 is arranged at a certain angle to the extension portion 61 and the button 1 respectively, that is, the connecting rod 62 is set at an obtuse angle to the movement direction of the button 1, so as to ensure smooth radial movement when pushing the button 1. This is an indirect action on the button 1, which has the advantage of not directly pushing the button 1 to move. Even if an accidental touch occurs and the movable cover 4 is subjected to a certain external force, it can delay the action of the movable cover 4 on the button 1, thereby reducing the effect of accidentally opening and pressing the button 1.

[0045] Of course, the extension portion 61 can also directly act on the button 1 through the inclined surface or the arc surface to realize the umbrella opening or closing action, but it does not have the delay or buffering effect after the connecting rod 62 is bridged.

[0046] The handle 2 is hollow cylindrical and is equipped with an umbrella-opening structure (this is the existing technology) inside. The umbrella-opening structure (not shown in the figure) is triggered by the button 1; a through hole 21 for the button 1 to pass through and a raised portion 22 of the limiting structure are provided on the outer wall of the handle 2; after the raised portion 22 of the handle 2 is assembled with the travel limiting groove 411 of the hanging ear 41 on the movable cover 4, it is fixed to the outer shell 3 so that the movable cover 4 can be displaced linearly along the axial direction of the handle 2.

[0047] When actually assembling and using: Figure 1-5 As shown,

[0048] (1) Insert the movable cover 4 into the middle rod and then install the handle 2, or insert the movable cover 4 from the other end of the middle rod;

[0049] (2) The button 1 and the umbrella opening structure are installed in the handle 2, and the button 1 is able to move in the radial direction (the button 1 is limited by the thickness of the handle 2 shell and can only move in the radial direction); the part of the button 1 exposed outside the handle 2 forms a part that is hinged to the connecting rod 62, and one end of the connecting rod 62 is installed through the pin A so that the connecting rod 62 and the button 1 are hinged;

[0050] (3) Insert the spring 5 (i.e., elastic member) axially between the movable cover 4 and the handle 2;

[0051] (4) Align the lug 41 on the movable cover 4 with the protrusion 22, and engage the travel limit groove 411 of the lug 41 with the protrusion 22. This restricts the movable cover 4 to axial displacement, preventing circumferential rotation and radial translation. This ensures that the movable cover 4 moves smoothly and that the connecting rod 62 and the button 1 are not stuck when they are subsequently driven to move.

[0052] (5) The other end of the connecting rod 62 of the reversing structure 6 is also mounted on the extension portion 61 of the movable cover 4 through a hinge shaft, so that when the movable cover 4 moves downward toward the handle 2, the connecting rod 62 drives the button 1 to move radially inward; otherwise, it is pulled outward;

[0053] (6) The housing 31 is sleeved on the outside of the handle 2 and the reversing structure 6, and the handle 2 is then fixed to the housing 31;

[0054] (7) The anti-slip sleeve 7 is axially sleeved into the groove of the housing 31; finally, the base 32 is fixed to the housing 31 to complete the entire assembly process.

[0055] When using:

[0056] (1) After holding the housing 31 with your palm, place your fingers on the end of the movable cover 4 and pull the movable cover 4 downward to move it toward the base 32;

[0057] (2) When the movable cover 4 moves downward, due to the formation of the limiting groove and the cooperation with the protrusion 22, the movable cover 4 can only move downward in a straight line, thereby driving the extension 61 downward; and the connecting rod 62 hinged to the extension 61 also has a tendency to move downward, but because the other end of the connecting rod 62 is hinged to the button 1, the button 1 restricts the downward movement of the connecting rod 62, and the connecting rod 62 and the button 1 are set at an obtuse angle. When one end of the connecting rod 62 has downward pressure, the button 1 at the other end is displaced radially toward the inside of the handle 2, thereby pushing the button 1 to open the umbrella opening structure inside the handle 2, thereby realizing the umbrella opening or closing action;

[0058] (3) Then release your finger, and under the action of the spring, the movable cover 4 moves upward in the opposite direction, driving the connecting rod 62 to move upward, and also driving the button 1 to reset outward;

[0059] (4) When the palm of the hand holds the housing 31, the anti-slip cover 7 supports the palm position, making it less likely to slip, and applying force with the fingers is smoother.

[0060] The utility model provides an umbrella handle mechanism for an automatic umbrella, which has a simple structure, is easy to manufacture, easy to implement, and low in cost. It solves the problem of existing automatic opening and closing umbrellas being easily opened by accident and the elastic force generated during instant opening causing damage to people or objects. The umbrella handle mechanism of the utility model adopts a movable cover, an elastic member, and a reversing structure, breaking the limitation of the conventional umbrella handle directly pushing a button to radially open the umbrella body. The opening direction is changed to an axial movement, which is then converted into radial displacement of the button. This arrangement significantly reduces the probability and risk of the button being accidentally pressed (the movable cover is axially arranged between the outer shell and the umbrella body and is generally difficult to contact the outer end of the outer shell or the umbrella body when touched by external force). It also expands the operating area. More importantly, it provides greater comfort when pressing with fingers. In actual use, the umbrella handle is held by the palm of the hand, and the finger presses the end surface of the movable cover and pulls it inward from the handle. This is in the same direction as the movement of the finger joint, making it more comfortable to pull the movable cover. Compared with the conventional radial pressing method, the thumb has less room for movement and must overcome the resistance of the spring inside the button. The utility model has the function of preventing accidental touches, reduces the operating force, and easily enables one-handed operation. The limiting structure of the present invention not only ensures that the movable cover will not fall out of the housing or the handle in the axial direction, but also ensures that the movable cover can be displaced linearly as a whole in the axial direction, thereby ensuring that the reversing structure can push and pull the key smoothly when acting on the key, and prevents jamming and failure. The reversing structure of the present invention adopts a two-stage drive structure, and the reversing structure formed by the cooperation of the extension part and the connecting rod ensures that even if a large external force is received, it will not directly act on the key (that is, the key will not be triggered instantly), and the force is transmitted through the connecting rod with ease, thus ensuring safety and providing a better operating experience. The movement direction of the connecting rod and the key is set at an obtuse angle in the present invention, so that the movable cover can smoothly drive the key to move when it moves downward. The present invention is also provided with an anti-slip sleeve to prevent slipping due to sweat or an umbrella when the hand is grasping, and to enhance the support capacity of the palm after gripping, so as to cooperate with the fingers pulling the movable cover to facilitate the application of force. In addition, the annular arc portion is provided on the movable cover to facilitate the operation of the movable cover displacement.

[0061] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation on the protection scope of the present utility model.
