Description

Telescopic folding umbrella {TELESCOPIC TYPE PARASOL}

The present invention relates to a folding parasol of a telescopic method, and more particularly, to a telescopic folding parasol that is advantageous for storage because it can be reduced and extended in a simple sliding manner.

In general, parasols are used to rest in the shade created by blocking the sun's light in summer or to avoid rain, and are widely used in beaches, shops, and fishing grounds.

The basic structure of the parasol has an upper hub at its top, centered on a central strut, and one end of a number of upper ribs is fixed to the upper hub, and the upper ribs are connected to each other through a sunshade.

The lower hub has a lower hub at the bottom of the prop, and the lower hub is movable around the main shaft, and one end of the lower rib is connected to the upper rib and the other end is fixed to the lower hub.

In large cases, the function of avoiding the sun rays or rain, which is the pretext of the sunshade, may not be possible. Therefore, the function of expanding the sunshade as needed and the ability to effectively avoid the sun rays or rain by bending one end of the sunshade inside need.

Currently, tents and parasols have been registered, filed, and marketed in several ways.

Among them, large tents and parasols used for outdoor events, etc., are difficult to store and move, and when folded, they are too large to be loaded in ordinary passenger cars.

In order to compensate for these shortcomings, a product that is double-folded is also devised. However, it is not an exaggeration to say that there are no products that are easy to use due to the collapse of large parasols and the ease of folding.

As a technology that can be easily stored when the sunshade membrane of the parasol is expanded or reduced by the size of the sunshade,'Parasol with adjustable shading area' of Korean Utility Model No. 20-0254306,'Foldable Parasol of Korean Patent Registration No. 10-0589682' And'parasol for easy assembly and detachment' of Korean Patent Registration No. 10-1734682.

However, the above prior arts increase the area of the sunshade membrane, but the size that can be substantially widened is small, so the degree of expansion and contraction of the sunshade membrane is not practical, and the detachable assembly method is also less practical due to the complexity of installation. Adjusting the awning area with is not enough to withstand the load of a large parasol at the joint.

The collapsible parasol of the stretch type according to the present invention, unlike the conventional collapsible parasol, applies a stretch type, reinforces mechanical strength to a portion having a stretch structure, and it is possible to reduce a large parasol to a small size, even when expanded. It is suggested that no overturning or force occurs.

As shown in FIG. 1, the folding parasol 10 of the telescopic method according to the present invention maintains a pillar 11 serving as a pillar, a sunshade film 12 that shields sunlight, and a sunshade film 12 in a constant shape. The main ribs 13 and the auxiliary ribs 14 connected to the main rib 13 and having a structure for folding or unfolding the sunshade 12, the top of the prop 11 and the center of the sunshade membrane 12 It is formed on the upper hub 15 to connect the main flesh (13), the lower hub 16 is formed in the middle of the support 11 and connected to the auxiliary flesh (14), and the sunscreen 12 When it can be made to include a catch 17 for fixing the lower hub 16 to maintain the state.

The main tread 13 may be made of a fixed tread 22 positioned inside the sunshade membrane 12 and a movable tread 21 sliding in association with the fixed tread 22.

The folding parasol 10 of the present invention is a structure in which the movable base 21 is stretched while sliding through the fixed base 22 and thus the sunshade membrane 12 is also stretched, so that it is possible to make a large parasol into a small parasol. do.

Figure 3 is a structural diagram of the connection of the pillar and the rib of the folding parasol of the telescopic method according to the present invention.

As shown in Figure 3, looking at the connection structure of the main stem 13 and the main stem 13 of the parasol 10 (Fig. 3 is shown in the reverse position of the parasol), the upper end of the prop 11 The upper hub 15 may be connected, and the lower hub 16 may be connected to the middle upper side.

In the upper hub 15, connection grooves corresponding to the number of main salaries 13 are formed at equal intervals in the circumferential direction, and one end of one bracket connecting member 131 may be fastened to one connection groove.

The other end of the bracket connecting member 131 is connected to one end of the fixed rib 22, and the other end of the fixed rib 22 is passed through the first slider 133 and the second slider 134, the third slider 135 Can be fixed on.

The movable base 21 is fixed to the first and second sliders 133 and 134 via the third slider 135, and the other end can be coupled to the sunshade connecting member 136.

One side of the second slider 134 may be connected to one end of the auxiliary stile 14 via a hook 141, and the other end may be fastened to one connection groove of the lower hub 16 via a hook 141. have.

Figure 4 is a structure and connection structure of the folding parasol of the telescopic system according to the present invention.

(A) is a state in which the movable base 21 is slid to the maximum relative to the fixed base 22 from the main base 13 of the parasol 10, and the main base 13 when the parasol 10 is unfolded The total length is shown, and (B) shows the length of the minimum main main body 13 by sliding the movable main body 21 relative to the fixed main body 22, and after folding the sunshade film 12 of the parasol 10 It shows a state in which the length of the main rib 13 is reduced.

(C) shows the opposite side of (A) in order to show the fixed structure between the first to third sliders 133, 134, 135 and the movable base 21 and the fixed base 22.

The number of movable steps 21 and the fixed steps 22 may have a relationship of ±1.

If the number of movable steps 21 is n (n is a positive integer), the number of fixed steps 22 is n+1, and if there are n number of fixed steps 22, the number of movable steps 21 may be n+1. FIG. 3 shows a case where there is one movable salary 21 and two fixed salaries 22 as a preferred example.

The parasol 10 of the present invention adopts a folding structure of a telescopic method, and the telescopic method adopts a sliding method by a plurality of coupling structures of a movable rib 21 and a fixed rib 22, thereby forming an existing single rib. Since it supports the sunshade film 12 with a plurality of supports that support the structure, it can have a structure capable of solving the defect of mechanical weakness in the coupling portion during expansion and contraction.

An elastic body 137 may be fitted to one or more of the fixed ribs 22, and the elastic body 137 may be located between the bracket connecting member 131 and the first slider 133, and the bracket connecting member ( Since 131) is fixed and the first slider 133 is a movable member, the elastic body 137 may be stretched through one side.

The elastic body 137 is reduced by elongation by elasticity in a state in which the parasol 10 is contracted, and when the parasol 10 is grasped and held by the supporter 11 in this state, the auxiliary flesh 14 is expanded in the radial direction. The movable stile 21 is unfolded in the radial direction in conjunction with the second slider 134 to which the auxiliary stile 14 is connected, so that the sunshade film 12 can be fully unfolded.

At this time, the elongation by elasticity of the elastic body 137 is made while the sunshade film 12 is unfolded, thereby preventing the sunshade film 12 from being turned over. That is, since the inverted direction of the sunshade film 12 and the elastic direction of the elastic body 137 are almost vertical, the inverted force and elastic force of the sunshade film 12 may be canceled, so that the reversal of the sunshade film 12 by the elastic body 137 is prevented. May be possible.

In addition, it can be easily expected that the sunshade film 12 is flipped by wind or gust in the state where the parasol 10 is unfolded, but in the present invention, the sunshade film 12 is provided because the elastic body 137 is fitted to the fixed rib 22 to be elastically supported. When the flip is over, it can be prevented from being flipped by the elastic body (137).

Referring to (C), the bracket connection member 131, the fixing member 132, and the sunshade connecting member 136 are connected to respective members at a fixed position.

Alternatively, the first to third sliders 133, 134, and 135 may be variably changed in position according to sliding of the movable base 21, rather than a fixed position.

The first and second sliders 133 and 134 are configured as separate objects for convenience, but may be configured as one slider.

The first to third sliders 133, 134, and 135 may have three holes formed horizontally in parallel.

Each of the three holes may be fitted with a fixed rib 22 and a movable rib 21, and among the three holes, a movable rib 21 may be fitted in the middle hole, and a fixed rib 22 in two holes on both sides, respectively. ) Can be embedded.

The movable base 21 is fixed by the fixing pins 138 in the first and second sliders 133 and 134, and the fixing base 22 is fixed by the fixing pins 138 in the third slider 135. .

The movable tread 21 is placed in a state to be slidable in the third slider 135, and the fixed tread 22 is in a state to be slidable in the first and second sliders 133 and 134 Can be set as

By configuring in this way, the movable base 21 is stretched and interlocked with the first and second sliders 133 and 134, and the fixed base 22 is configured to be capable of sliding the first and second sliders 133 and 134. It is possible, the fixed slider 22 by the third slider 135 is fixed in its position and the movable base 21 can be configured to be slidable via the third slider 135.

When contracted in the ⓐ direction, the parasol 10 can be folded, and when extended in the ⓑ direction, the parasol 10 can be extended, and the distance L between the fixing member 132 and the first slider 133 is maximum. Elongation as long as L is possible (actually 80 to 90% of L is possible), and L can be determined in correlation with the length of the abutment 14.

In addition, the width of the fixing member 132 and the width of the first slider 133 are different, and the width of the first slider 133 is larger than the width of the fixing member 132.

By doing this, the distance between the fixed ribs 22 establishes a W1<W2 relationship, which means that the distance between the fixed ribs 22 becomes narrower toward the center of the parasol 10, and the fixed rib 22 Since the interval of the narrower, as the first slider 133 moves toward the center of the parasol 10 by sliding, the fixed tread 22 inserted in the hole to be formed in the first slider 133 is brought into close contact with each other, and eventually There is no further sliding at a position close to the fixing member 132, and the reduction due to sliding is placed in a stopped state.

This can be automatically performed by sliding to stop the sliding for reduction when reaching a certain position when the movable base 21 is reduced by sliding.

Figure 5 shows the connection structure of the main and support ribs of the folding umbrella of the telescopic method according to the present invention.

As shown in FIG. 5, it is possible to examine the mechanical connection structure of the main rib 13 and the secondary rib 14 in a state where the parasol 10 is unfolded.

When the sunshade film 12 is unfolded, the main salvage 13 is unified and unfolded with the sunshade film 12, and the secondary salvage 14 supports the sunshade film 12, so that it can be positioned at a larger angle than the main salvage 13 have.

At this time, the auxiliary tread 14 and the second slider 134 are connected to be interlocked when the movable tread 21 is sliding, so that the auxiliary tread 14 can have a structure to move.

The auxiliary stile 14 is rotatably connected to the second slider 134 and the hinge shaft 154 via the hook 141, and the hook 141 may come into contact with the brake 151, and the brake ( The lower surface of the 151 side may be configured such that the elastic addition body 152 contacts the upper surface of the fixed rib 22.

At this time, since the brake 151 is in contact with the auxiliary stile 14, the auxiliary sill 14 is pushed outward from the inside of the awning film 12 in the state where the awning film 12 is unfolded, so the auxiliary sill 14 is assisted to assist the awning film 14 (12) to be able to support firmly. It also has a function that can prevent the back of the sunshade film 12.

In addition, the fixed rib 22 and the elastic adder 152 are in contact with each other, and in detail, the support 152a and the fixed rib 22 are brought into contact with the elastic film 152b, and the elastic adder 152 ) Leverages the lever 153 to have a slight flow elastically.

This can cause the parasol's sunshade film 12 to flow up and down due to wind, and at this time, shaking by the wind between the fixed tread 22 and the second slider 134 in a state where the auxiliary tread 14 and the brake 151 come into contact with each other. By absorbing the elastic, it is possible to prevent the shaking at the time of vertical flow by the wind.

6 is a variety of examples of the main rib of the folding parasol of the telescopic method according to the present invention.

As shown in FIG. 6, the number of movable ribs 21 and fixed ribs 22 of the main rib 13 of the present invention may have a difference of ±1.

As described above, the movable base 21 and the fixed base 22 of the main base 13 of the present invention can be variously implemented with a difference of ±1, but only the movable base according to the installation cost, installation area, and operability. It will be efficient to properly adjust the number of 21) and fixed ribs 22.

7 is a structural diagram of the connecting members of the telescopic folding parasol according to the present invention.

As shown in FIG. 7, the connecting members of the flesh have one or more holes, and the number of these holes may vary depending on the number of the movable flesh 21 and the fixed flesh 22.

In the case of FIG. 7, as shown in FIG. 4, one movable salary 21 is one and two fixed salaries 22 are examples.

In the bracket connecting member 131, two connecting holes 1311 are formed so that the fixed rib 22 is fastened to the lower hub 15, and the fixed rib 22 is perfectly fixed to the fixed member 132 Two fixing holes 3121 may be formed.

Three holes are formed in the first and second sliders 133 and 134, and the hole in the center is a fixed hole 1332 and 1342 in which the movable trough 21 is fixed, and the holes on both sides are fixed troughs 22 ) May be inserted to form slide holes 1331 and 1341 through which the first and second sliders 133 and 134 can slide based on the fixed rib 22.

The third slider 135 is formed of three holes, and the holes on both sides are fixed holes 1352 in which the fixed ribs 22 are inserted and fixed, and the holes in the center are movable by inserting the movable ribs 21 The flesh 21 may be a slide hole 1351 that can be slid.

8 is a structural diagram of a first slider of a folding parasol of the stretch method according to the present invention, FIG. 9 is a structural diagram of a second slider of a folding parasol of the stretch method according to the present invention, and FIG. 10 is a structural diagram of the stretch method according to the present invention It is a structural diagram of the third slider of the folding parasol.

The first slider 133 includes a body 1330, a slide hole 1331 and a fixing hole 1332, and the second slider 134 includes a body 1340, a slide hole 1341, and a fixing hole 1342. , Auxiliary slit connection (1343), may include a lever 153 and a brake 151, the third slider 135 supports the body 1350, slide hole 1351, fixing hole 1352 and auxiliary slit It may be made of a member 1354.

The first to third sliders 133, 134, and 135 may each have three holes, and the three holes may be made of a slide hole and a fixed hole.

As described above, the slide hole does not fix the base so that the slider can slide relative to the base, and the fixing hole is fixed by the base and the fixing pin 138.

Here, protrusions 1333, 1346, and 1353 may be formed at intervals of 90 degrees on the inner circumferential side of the slide holes 1331, 1341, and 1351.

The slide holes 1331, 1341, and 1351 are inserted into the movable base 21 to make the movable base 21 slidable, or the fixed base 22 is inserted into the first and second sliders 133 based on the fixed base 22. , 134) is to be slidable to promote the expansion and contraction of the main trough (13).

At this time, since the inner diameter of the slide hole and the diameter of the stile do not make a big difference, when the outer surface of the sill and the inner surface of the slide hole come into contact with the flow, frictional force may interfere with the freedom of sliding.

To prevent this, by forming four protrusions (1333, 1346, 1353), by contacting the four protrusions (1333, 1346, 1353) with the four outer circumferences of the movable axle (21) and the fixed axle (22) It is possible to configure a free sliding by minimizing friction.

11 shows an example of the structure of another slider of the folding umbrella of the telescopic method according to the present invention.

Referring to FIG. 11, another slider 134a is an example in which the first and second sliders 133 and 134 shown in FIGS. 8 and 9 are combined into one, and the slide hole is modified.

The first and second sliders 133 and 134 shown in FIGS. 1 to 10 are only divided into two for convenience, and even if the two sliders are combined into one to widen the width, the same problem to be achieved by the present invention can be achieved. have.

In this regard, FIG. 11 shows another slider 134a combined into one rather than two different types of sliders.

The biggest difference between the other sliders 134a and the first and second sliders 133 and 134 may be whether the slide hole and the fixing hole are arranged horizontally or the outside is arranged in a triangular shape.

The other slider 134a may have two inclined inclined slide holes 1341a through which a fixed groove 1342a in which the movable trough 21a is fixed is formed on the other side.

When the movable base 21a is extended to the maximum, the fixed base 22a is positioned below the inclined slide hole 1341a, and when the movable base 21a is contracted to the maximum, the fixed base 22a is inclined to slide the hole 1341a. Located on the upper side of the movable base 21a and the fixed base 22a are placed in a triangular arrangement position.

Accordingly, it will be said that the hole shape of the slider of the present invention is no different from implementing the stretching method of the sunshade film by the sliding structure of the present invention regardless of whether it is a horizontal or triangular arrangement.
