Definitions
- the present invention relates to a portable telescopic umbrella according to the preamble of claim 1 or 4.
- main ribs to be folded are normally composed of two pieces or three pieces of ribs.
- An object of this invention is to settle with problem stated in the foregoing and to provide a compact telescopic umbrella.
- the umbrella is constructed in such a way that an upper unit is provided on a tip of a middle rod, and a lower unit is provided slidably on the middle rod.
- an end of the main rib consisting of four pieces of ribs that are mutually and axially supported, and the main rib and the lower unit are connected by means of a receiving rib. With the vertical sliding motion of the lower unit, each rib of the main rib is positioned in a straight line or is folded.
- a side curved portion and an inclined portion are formed on the third rib, and with this construction, when the main rib is folded, a portion at an opposite side of the third rib is not superposed on a portion at an opposite side of the axial support portion of the second rib and they are mutually adjacent to each other.
- a four-side link mechanism is formed by means of a link rib.
- the first rib and the third rib are connected by a connecting rod
- the second rib and the fourth rib are connected by means of a connecting rod, whereby a four-side link mechanism is respectively formed between the connecting rod and the main rib and the connecting rod and the main rib.
- Reference numeral 2a denotes a shaft, and a handle 4 is fixed to the lower end of the shaft.
- a slide shaft 2b is fitted and disposed in the shaft 2a, and in the slide shaft 2b, a slide shaft 2c is fitted and disposed.
- an upper unit 8 formed with a projection is fixed on an upper end of the slide shaft 2c.
- the shaft 2a and the slide shafts 2b, 2c constitute an extendable core type middle rod 2.
- Numeral 10a denotes a first rib, and its one end is pivotally and slidably supported on the upper unit 8.
- the first rib 10a is disposed in a plural number around the upper unit 8 and is pivotally supported.
- the drawing in order to clarify the construction of this invention clearly, it shows only one piece, namely, the first rib and other first ribs are omitted in the illustration.
- One end of the second rib 10b is pivotally supported on the other end of the first rib 10a, and one end of the second rib 10b is pivotally supported 14 as per the illustration, and one end of the third rib 10c is pivotally supported 16 on the other end of the second rib 10b as shown in the illustration.
- the other end of the third rib 10c is pivotally supported 20 on a connecting member 18, and the other end of the connecting member 18 is fixed with the fourth rib 10d.
- the ribs 10a, 10b, 10c, 10d constitute an extendable main rib 10.
- Numeral 22 denotes a receiving rib, and its one end is pivotally supported 24 on lower unit 5, and its other end is pivotally supported 26 on a middle portion of the first rib 10a.
- Numeral 28 denotes a link rib, and its one end is pivotally supported 30 in the vicinity of the receiving rib 22, and the other end is pivotally supported 32 on the one end of the second rib 10b.
- the link rib 28 constitute a four-side link mechanism 34 between the link rib 28 and the receiving rib 22 and the ribs 10a and 10b.
- Numeral 36 denotes a first connecting rod made of a resilient wire, and its one end is pivotally supported 38 in the vicinity of the other end of the first rib 10a, and its other end is pivotally supported 40 on one end of the third rib 10c.
- the first connecting rod 36 constitute a four-side link mechanism 44 between the ribs 10a and 10b.
- Numeral 46 denotes a second connecting rod made of a resilient wire, and its one end i5 pivotally supported 48 in the vicinity of the other end of the second rib 10b, and its other end is pivotally supported 50 of one end of the connecting rod 18.
- the middle portion of the second connecting rod 46 is slidably engaged with an engaging member 42 formed in the middle portion of the third rib 10c.
- the second connecting rod 46 constitutes a four-side link mechanism 52 between the ribs 10b and 10c and the connecting member 18.
- the third rib 10c is formed with a side curved portion 54 and an inclined portion 56, and the side curved portion 54 forms a clearance so that the other portion 19c' toward the connecting member 18 of the rib 10c is not superposed on the one portion 10b' of the rib 10b.
- the inclined portion 56 is arranged to be adjacent so that the other portion 10c' of the rib 10c and the one portion 10b' of the rib 10b are in close contact.
- a canopy is spanned with an umbrella cloth or material (illustration is omitted).
- the rib 10a lifts by the receiving rib 22, and the rib 10a swivels in a direction as shown in Fig. 2 where an angle ⁇ formed with the middle rod 2 expands with the upper unit 8 as a pivot.
- the rib 10b swivels in a direction where an angle ⁇ formed with the rib 10a expands by the operation of the four-side link mechanism 34 having the link rib 22 as a constituting element.
- the rib 10c swivels in a direction where an angle ⁇ formed with the rib 10b expands by the operation of the four-side link mechanism 44 having the first connecting rod 36 as a constituting element. Furthermore, according to a change of an angle ⁇ formed with the rib 10b against the rib 10c, the connecting member 18 swivels in a direction where an angle ⁇ with the rib 10c expands by the operation of a four-side link mechanism 52 having the second connecting rod 46 as a constituting element.
- each rib 10a, 10b, 10c, 10d When the lower unit 5 lifts to an upper end engaging position of the middle rod 2, each rib 10a, 10b, 10c, 10d, as shown in Fig. 3, form a straight line, and produces the umbrella in open condition. In this condition, the lower unit 5 is engaged with the middle rod 2 in releasable condition by a repulsion (illustration is omitted). When the engagement of the lower unit 5 is released, and the lower unit 5 slides in a lower direction along the middle rod 2, each rod 10a, 10b, 10c, 10d is folded as shown in Fig. 1 by the operation opposite the foregoing operation.
- the other side 10c' of the rib 10c is disposed adjacent to the one side 10b' of the rib 10b by the presence of the side curved portion 54 and the inclined portion 56, and they are not superposed in the radial and/or vertical direction, and each rib 10a, 10b, 0c, 10d is folded in compact form. Furthermore, the middle rod 2 reduces its size and the folding of the umbrella completes.
- this invention is so constructed that the telescopic umbrella becomes a compact construction.
