Description

Umbrella {A UMBRELLA}

The present invention relates to a new construction umbrella.

In general, the umbrella includes an umbrella rod having a rod shape, a top and bottom cloth supported on the upper end of the umbrella pivot so as to pivot up and down, an auxiliary fingers one end of which is rotatably connected to the intermediate portion of the top fingers, And a slider that slides up and down on the umbrella stand.

These conventional umbrellas are separated from each other, and since they have to be rotatably supported, they are not only poor in durability but also are difficult to manufacture, resulting in increased manufacturing costs.

It is an object of the present invention to provide a new structure umbrella which is simple in structure and durable and can reduce manufacturing cost.

The umbrella for achieving the above-mentioned object of the present invention includes an umbrella stand on a long bar; A flange provided at an upper end region of the umbrella stand; A sliding rail base on which an upper end portion is rotatably supported along a tangential direction to an edge region of the flange, and an upper edge portion having opposite ends connected to at least a portion of the sliding rail base; And a slider having a sliding guide portion that is movable up and down along the umbrella frame with an ascending and descending axial hole through which the umbrella member passes and which engages with the lifting and lowering movement to unfold and fold and fold the umbrella. The umbrella of the above-mentioned structure has a merit of a simple structure, a good durability and a convenient manufacturing because the umbrella cloth and the sliding rail base are integrally formed.

The edge of the flange is polyhedral and the umbrella is rotatably supported in a tangential direction with respect to each side of the flange.

Wherein the umbrella member is a rod having a non-circular cross-section and the ascending and descending axial hole of the slider is a non-circular hole corresponding to the non-circular rod of the umbrella member and the slider rotates about the umbrella member in the unfolded state or the folded state It is possible to prevent the slider from naturally moving up and down by keeping the unfolded state or the folded state.

The sliding rail base is designed to extend so as to gradually widen the gap from the heel base and to narrow the gap again. The sliding rail base is designed to include a hook at a portion adjacent to the flange, thereby preventing the slider from naturally moving downward in the unfolded state can do.

The slider preferably includes an aligning portion that restrains a free end of the umbrella when the umbrella is moved downward to apply a force in a direction in which the slider rotates about the umbrella. At this time, since the slider is subjected to a force in a rotating direction in a state in which the umbrella shaft is prevented from rotating, it is possible to prevent the slider from being raised and lowered naturally. In addition, the alignment part also aligns the folded umbrella pieces.

The umbrella according to the present invention is simple in structure, has excellent durability, and has an economical effect of reducing the manufacturing cost.

Further, the umbrella according to the present invention can be completely opened or folded even if the slider is raised or lowered relative to the umbrella stand, thereby providing convenience to the user.

Hereinafter, the umbrella 100 according to the present invention will be described with reference to FIGS. 1 to 5. FIG.

1 and 2, the umbrella 100 includes an umbrella 110 on a long rod, a flange 120 extending in the longitudinal direction of the umbrella stand 110 in the upper region of the umbrella stand 110, A sliding rail base 132 whose upper end is rotatably supported along the tangential direction to the edge region of the flange 120 and a top edge 134 which is connected to at least a portion of the sliding rail base 132 at both ends, And a sliding guide portion 144 which is movable up and down along the umbrella stand 110 and has an elevation shaft hole 142 through which the umbrella stand 110 passes and which is engaged with the sliding rail stand 132 And a slider 140 for rotating the folding and folding of the umbrella body 130 in conjunction with the lifting and lowering movement.

The umbrella bed 110 is made of, for example, metal or plastic and has a bar shape of substantially rectangular cross section. Here, the umbrella stand 110 is not limited to a quadrangular shape, and can be applied to a bar surface of a non-circular cross section to prevent the inserted slider 140 from rotating completely. The umbrella stand 110 has a flange 120 at its upper end and a handle 150 at its lower end.

The flange 120 is formed as a polygonal column having a plurality of side surfaces 124 in the form of a horizontally extended shape in the longitudinal direction as shown in Fig. Here, the flange 120 does not necessarily have to extend in the lateral direction. On each side surface 124 of the flange 120, a projection receiving portion 122 for rotatably supporting the end portion of the umbrella body 130 is disposed. The projection receiving portion 122 is made to extend downward from the upper end of the flange 120. The engaging projection 136 of the umbrella stand 130 may be inserted into the projection receiving portion 122 from above to below and then the cover 125 may be fixed to prevent the inserted engaging projection 136 from being dislocated. The cover 125 may limit the rotation of the umbrella body 130 rotating as the extension shim larger than the side surface 124 of the flange 120 to rotate over the extended position. If the projection receiving hole is formed at the end of the umbrella body 130, a locking protrusion should be disposed on the side surface 124 of the flange 120. The projection receiving portion 122 and the locking projection 136 for rotating the umbrella body 130 in the direction in contact with the side surface 124 of the flange 120 can be applied in various forms as an example. In the case where the locking protrusion is fixed to the side surface of the flange 120, it is also possible to replace the locking protrusion with a screw having a head. The upper surface of the flange 120 or the upper end of the umbrella stand 110 includes a ceiling portion 112 for fixing and supporting the center of the umbrella cloth 101.

4 (a) and 4 (b), the umbrella arm 130 has a sliding rail base 132 whose upper end is rotatably supported along the tangential direction to the edge region of the flange 120, And a topsheet 134 both ends of which are connected at least in part to each other. A locking projection 136 is disposed at the end of the umbrella body 130 which is coupled to the projection receiving portion 122 disposed on the side surface of the flange 120. The locking projection 136 should be received in the projection receiving portion 122 and be made to be suitable for rotation.

The sliding rail base 132 is formed in a circular cross section in an unrestricted form. The sliding rail base 132 is gradually extended from the locking pawl 136 to the heavier pawl 134 and extends so as to be gradually narrowed again. At this time, the sliding rail base 132 may selectively include a locking protrusion 138 having a bent portion near the locking protrusion 136. The stopping jaw 138 may serve to prevent the slider 140 from being naturally lowered and folded in a fully extended state. That is, when the slider is not lowered by forcibly applying a force, the slider 140 can be prevented from descending by the bent portion. 4 (b), the sliding rail base 132 extends beyond the stopping jaws 138 and extends beyond the maximum spaced point 139 with the topsheet 134, As shown in FIG. The sliding rail base 132 is bent again at the intermediate engaging portion 137 engaging with the top end stop 134 and extends in the opposite direction.

The topsheet 134 is made of an elliptical cross-section in an unrestricted form. The free standing cloth 134 serves to fix the umbrella cloth 101 and is integrally formed with the sliding rail base 132. [ The heavily cloth 134 includes a bent portion 135 bent in a direction emerging from the paper surface of Fig. 4 (a). This bending portion 135 is for preventing the sliding rail bail of the adjacent umbrella piece from colliding in a folded state. That is, when the umbrella is folded, the left adjacent sliding rail base is bent at the top end of the top and bottom to prevent interference that is not folded.

The reason why the top end stop 134 is formed in an elliptical shape is that when the slider 140 moves on the sliding rail base 132, the sliding guide portion 144 of the slider 140, when passing through the intermediate coupling portion 137, So that the sliding rail portion 132 housed in the sliding guide portion 144 does not escape.

The slider 140 moves up and down along the umbrella stand 110 with the elevation shaft hole 142 through which the umbrella stand 110 passes. The slider 140 has a sliding guide portion 144 that engages with the sliding rail portion 132, and rotates the folding and folding of the umbrella body 130 in conjunction with the elevation movement. The elevating shaft hole 142 can prevent rotation when the umbrella stand 110 is received in an unlimited rectangular cross section. When the slider 140 is lifted or lowered, the slider 140 is moved in the direction in which the umbrella body 130 rotates, that is, the umbrella stand 110, by the sliding rail base 132 inserted in the sliding guide portion 144, As shown in Fig. The force in the rotating direction of the slider 140 with respect to the umbrella table 110 in a state in which the slider 140 can not rotate can prevent the slider 140 from moving up or down with respect to the umbrella table 110. As a result, it is possible to prevent the slider 140 from rising and falling naturally on the umbrella bed 110 in the unfolded or folded state. Of course, the ascending / descending suppression should be able to be released by the force applied by the user. In other words, the force to rotate by the force of the user is suppressed in the raising and lowering process of reaching the extended position or the folded position of the slider 140, and when the slider 140 is released in the extended or folded state, State can be maintained. Of course, it is not preferable that the slider 140 is prevented from being excessively lifted and lowered, and sufficient to withstand an external environment such as wind.

The sliding guide portion 144 is formed in a partially opened and closed configuration in the extended portion 143 extending in the radial direction from the pillar portion 141 formed with the elevating shaft hole 142. The sliding guide portion 144 moves along the sliding rail portion 132 inserted when the slider 140 moves along the umbrella frame 110 by receiving the sliding rail portion 132. As a result, the umbrella 130 can be unfolded or folded as the sliding rail base 132 moves along the fixed route.

The slider 140 includes alignment protrusions 146 arranged to evenly align the folded umbrella 130 at the bottom as shown in Fig. Since the umbrella shell 130 has a certain curvature, the width of the umbrella shell 130 is wide around the umbrella stand 110 in a folded state. As a result, the folded umbrella is not simple and can be blunt. Therefore, in order to solve this problem, the alignment protrusion 146 can be lowered while supporting the end portion of the umbrella fingers 130 when the slider 140 is lowered, thereby increasing the overall curvature of the umbrella fingers. That is, the end of the umbrella body 130 can be prevented from rotating further in the state where the end of the umbrella body 130 is caught by the alignment protrusion 146. By preventing the end of the umbrella fence 130 from being forcibly rotated, the slider 140 is urged in the direction of turning right against the umbrella stand 110. [ As a result, in a state in which the slider 140 can not rotate, since the force is applied in the direction in which the slider 140 rotates around the umbrella, the lifting and lowering of the slider 140 can be suppressed.

Although the principle of the present invention is not separately shown in the drawing, it is also applicable to a folding umbrella in two or three stages. More specifically, one or more auxiliary fingers (not shown) are foldably connected to one another in the one-way direction to the top fingers 134 after the intermediate coupling portion 137 where the sliding rail bands 132 are joined together, And the end of a steel wire (not shown) for controlling the movement of the slider 140 is coupled to the slider 140.

Hereinafter, the operation of the umbrella 100 according to the present invention will be described.

2 shows a folded state in which the slider 140 is lowered to the lowest position. Here, before the slider 140 is subjected to any forcible force, the slider does not move upward easily. This is because not only the slider 140 is being pushed in the direction of rotating relative to the umbrella stand 110 but also the user's force is required to pass through the intermediate joint inflection point of the sliding rail base 132.

Thereafter, when the slider 140 is forcibly lifted and moved about the umbrella stand 110, the sliding rail base 132 moves along the sliding guide unit 144 while receiving the resistance. At this time, The umbrella shell 130 starts to rotate in the tangential direction of the flange 120 side.

After the guide portion 144 passes the inflection point 139 of the sliding rail base 132, the effect of the ceiling base 134 due to the deformation of the sliding rail base 132 is steadily reduced.

When the slider 140 reaches the unfolding position, since the slider 140 receives a force in the direction of rotating about the umbrella stand 110, the slider 140 does not naturally descend. As a result, there is no need for a separate locking device in the unfolded condition.

When the sliding guide portion 144 passes the latching jaw 138 of the sliding rail portion 132, the slider 140 is prevented from falling down naturally when the sliding guide portion 144 is selectively formed on the sliding rail portion 132. [ Can play a role. The latching jaw 138 may serve as an additional fixation in addition to the fixing as the slider 140 applies a force in the direction of rotating relative to the umbrella bed 110. [

When the umbrella is folded, when the slider 140 is rotated or moved down with a strong force, the slider 140 can pass through the latching jaw 138 and start falling.

As described above, the slider 140 and the umbrella stand according to the present invention are simple in structure since there is no need for the fixing means with the umbrella spread out and the fixing means with the folded state.

The durability can be improved by integrally manufacturing the umbrella body 130 by the ceiling body 134 and the sliding rail base 132.

In particular, the user can maintain the folded state and the unfolded state simply by raising and lowering the slider 140, which is very convenient to use.
