Detailed description of the invention

[Technical Field]

The present invention relates to an umbrella which is simple in structure and inexpensive.

[Background]

In general, conventional umbrellas have endpieces, one end of which is extended by a handle and the other end of which is movable in a radial plane and is joined by a plurality of radial umbrellas which are usually sewn and fixed with an umbrella cloth on it. It is made of an umbrella to form an end piece.

A socket installed to slide along an umbrella stand has one end connected to the socket and the other end connected to each umbrella by each stretcher, where the umbrella is articulated in the central region. In addition, clipping means are provided on the umbrella stand and the socket to hold the umbrella in the unfolded or folded position. Further, the umbrella is completed by adding a tassel and a sheath to maintain the folded state with respect to the umbrella stand in the folded position of the umbrella while protecting the feeling of the umbrella.

Since conventional umbrellas are made up of a large number of parts that require a relatively considerable amount of labor to assemble them, the production rate of the umbrellas is relatively high, making it very difficult to produce low-priced umbrellas.

It is therefore an object of the present invention to overcome these drawbacks of the prior art, and the present invention provides an umbrella which is very simple in design and which can be manufactured at high productivity, minimum labor and at a very low cost.

[Initiation of invention]

More specifically, the umbrella serves as the handle once, and the other end forms an end piece in which the radial ends are movable jointly in a radial plane between the extended position and the folded position with respect to the umbrella stand; Umbrella is fixed to the umbrella. According to the present invention, the umbrella is more axially oriented in an umbrella stand position between an open position in which a slider is folded to the umbrella pole and fixed to the open position and the closed position in which the umbrella is placed in a folded position relative to the umbrella stand. And a slider slidably installed therein, wherein a detachable locking means for allowing the slider and the umbrella to cooperate is additionally provided to temporarily fix the slider in an unfolded position.

Advantageously, these detachable locking means consist of means for clipping the slider on and / or on the umbrella stand. Furthermore, when the slider is in the folded position, the slider is formed to fix the umbrella string in the folded position.

Likewise, the umbrella flesh forms a single piece with an umbrella stand made of molded plastic material, for example. In this case, the umbrella flesh is connected to the end piece of the umbrella stand by a thin hinge.

The umbrella feel itself consists of a piece of plastic material that is suitably cut and fixed by bonding or welding to the umbrella meat.

As an example and not by way of limitation, one embodiment of the present invention will be described below with reference to the accompanying drawings.

Best Mode of the Invention

In the accompanying drawings, it is pointed out that the dimensions and measures of the umbrella and its parts have not been taken into account in order to facilitate understanding.

As shown in FIG. 1, the umbrella has three parts: a tubular member forming the umbrella stand 1 of the umbrella, and a handle 2 and a curved hinge portion 5 extending from the end of the umbrella stand. Umbrella persimmon made of molded plastic material consisting of a plurality of umbrella flesh (3) connected to the other end (4) of the umbrella stand and made of a single piece of plastic material as possible and directly bonded to the umbrella meat (3) 6) and a slider 7 made of a molded plastic material and installed slidably in an axial direction on the umbrella stand 1.

In this embodiment, the slider 7 has two tubular sections connected from end to end, namely: a primary section 8 whose inner diameter is approximately equal to the outer diameter of the umbrella stand 1, and which has a larger inner diameter. To the secondary section 9 which together with the umbrella stand 1 form an intercalated volume 10 which is annular and opened in the direction of the end 4 of the umbrella stand 1 on which the umbrella stand 3 is loaded. Is formed.

This slider 7, guided along the umbrella stand by the section 8, has two end positions, namely: from the end 4 of the umbrella stand 1 sufficient to allow the umbrella stem 3 to return to the umbrella stand 1. The folded position located far away and preferably near the handle 2 and sliding the slider towards the end 4 and the upper edge 11 of the section 9 accordingly is hinged to the hinge 5. Umbrella 3 is moved axially between the extended positions obtained by opening the umbrella 3 until it clips into the shoulder 12 formed in the nearest umbrella 3 (the position shown by the solid line in FIG. 1).

In the unfolded position, due to the elasticity of the hinge 5 the shoulder 12 exerts radial forces on the edge 11 of the slider 7 causing an axial locking and the unwinding is only in the direction of the handle 2. This is possible by pulling the slider 7.

In the unfolded position, furthermore, the axial locking of the slider 7 is, as in the embodiment shown in FIGS. 2 and 3: a radial notch 13 formed in the umbrella shell and opening at the height of the shoulder 12. And a lock obtained by providing a stop 14 projecting radially from the edge 11 of the section 9.

In this case, locking in the folded position is obtained by rotating the slider 7 so that the stop 14 engages in the notch 13. Of course, loosening is obtained by rotating the slider 7 in the opposite direction.

Another advantage of the slider 7 described above is that the slider allows the umbrella string 3 to be locked relative to the umbrella stand 1 in the folded position of the umbrella.

In practice, in the folded position, the slider 7 is moved towards the end 4 and then the end of the umbrella string 3 engages in the insertion volume 10 until the entire umbrella string is locked by jamming. (The position shown by the dotted line in FIG. 1).

In the folded position, this locking of the umbrella flesh eliminates the need for a sheath that is inconvenient to use and easily lost.

It is emphasized that these features are achieved despite the fact that the umbrella consists of only three parts that can be produced and assembled at a very low price.

In the embodiment shown in FIGS. 4 and 5, the upper end of the umbrella stand 1; A one-dimensional cylindrical portion 20 having a diameter smaller than that of the umbrella stand 1; A circular collar 21 having a crown-shaped upper radiation surface 22 forming a primary surface for fixing the umbrella meat 3; A circular shoulder 24 which forms a circular space with the collar 21 and has a conical shape at its upper end, and a base of radially and elastically deformable radially on the shoulder 24 and larger than the part 23. Has portions having axial cut-outs 25 forming tongues 26 terminated by cones 27 forming a steep step 28 It extends by the cylindrical part comprised by the two-dimensional cylindrical part 23. As shown in FIG.

Umbrella 3 made of a single piece using a molded plastic material is connected to the center member 29 by a reduced thickness portion forming the elastic hinge 30. These umbrella strings 3 have a small side located on the same side as the hinge 30 at a portion adjacent to these hinges 30 bounded by the protruding flange 33 toward the bottom or it is with respect to the inclined portion 34. An approximately triangular having a concave shape consisting of a floor 32 enclosed by a straight line that protrudes and is inclined toward the hinge 30 and extends approximately parallel to the umbrella stand 1 in the extended position of the umbrella At least one reinforcing member 31 of the.

The core member 29 has a central hole of a diameter approximately equal to the diameter of the cylindrical portion 23, and the cylindrical portion is forcibly joined together in the annular space between the steep step 28 and the shoulder 24. Is fixed by clipping.

The fixing of the umbrella stem 3 according to the fixing of the core member 29 is completed by a cap 35 of a cylindrical truncated-cone shape which clips to the cylindrical portion 23.

The cap 35 has a cylindrical portion 36 having an inner diameter slightly larger than the diameter of the base of the cone portion 27, and a lower edge 38 forming a large base has a diameter slightly larger than the diameter of the member 29. It has an open part 37 of the truncated corner shape.

In addition, the cylindrical portion has a cylindrical portion 39 having an internal profile approximately equal to the diameter of the cylindrical portion 23 inside the truncated corner portion and having an internal profile suitable for clipping on the shoulder 24 at the end thereof. Is extended by.

The cylindrical portion 39 recovers the initial position of the tongue at the end of the movement because the steep step 28 is engaged with the step of the hole 40 located at the connection portion between the cylindrical portion 39 and the cylindrical portion 36. This is to elastically deform the tongue 26 providing the axial lock of the cap 36 so as to fit freely in the cylindrical portion 23.

In this position, the edges 38 of the truncated cone shape 37 are each angular end of the travel locking of the umbrella stem 3 in order to avoid the umbrella overturning, for example because of wind. to provide.

The upper end of the cylindrical portion 36 of the cap 35 is closed by a closing plug 41 made of plastic material, for example.

In this embodiment, the slider 7 has a cylindrical lower end 42 having an inner diameter approximately equal to the outer diameter of the umbrella stand 1, and an upper edge 44 forming a larger base having a reinforcing member It has a truncated corner bell portion 43 having a shape almost supplemented to the concave shape of 31), that is, a shape having an approximately trapezoidal section.

In the folded position of the umbrella (FIGS. 4 and 6), the umbrella meat 3 whose end is engaged with the truncated corner portion 43 of the slider 7 extends substantially parallel to the umbrella stand 1.

From this position, the umbrella is opened by moving the slider 7 in a direction opposite to the cap 35 to release the umbrella string 3.

In the folded position, when the cylindrical portion 20 is freed with the movement of the slider 7, the reinforcing member 31 is in contact with the cylindrical portion 20 with a slight bend of the umbrella rib 3 so that they are in the half-opened position. Will be voluntary.

The slider 7 is then moved in the direction of the cap 35 such that the umbrella 44 is in the unfolded position by the action of the edge 44 on the umbrella string 3.

At the end of the slider movement, the edge 44 snaps into the concave shape of the reinforcement 31, so that the lock of the umbrella 3 in the open position and the top of the slider 7 at the upper end above the umbrella stand 1 All axial locking takes place.

This locking will be particularly self-supporting due to the force due to the elasticity of the hinge 30, and the recessed shape of the reinforcement 31 and the upper edge 44 of the slider 7 because it tends to fold the umbrella meat 3. The weight of the umbrella feel, as well as the weight of the umbrella feel and the body of the umbrella assembly, which reinforces the complementary convex shape of the body will probably become self-reliant.

Of course, the present invention is not limited to the above embodiment.

Thus, for example, the handle 2 may be fixed to an umbrella stand and may have a curved shape as shown in FIG.

Similarly, the umbrella stand 1 does not necessarily have to be tubular. Conversely, this umbrella stand 1 made of an extruded or injection plastic material may have an S-shaped cross section as shown in FIG.

This solution makes it possible to obtain an umbrella stand having good rigidity with minimal material by extrusion or injection.
