Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ◆/warping device for umbrellas that can be tilted as required, such as large umbrellas used at beaches, terraces, and ponds.

The present invention is particularly designed to provide a support for the umbrella so that in response to the winding 11 of the first part of the flexible cable, the umbrella can be opened and the umbrella can be tilted in response to the winding 9 of the second part. This relates to the improvement of leather with an attached winding device. Examples of such umbrella structures are disclosed in U.S. Pat. . U.S. Pat. No. 2,598,697 shows another type of monofilament body with a Kg winding device for opening and tilting the umbrella.

This single mechanism mechanism is equipped with a tiltable mechanism and a crank and gear mechanism that winds a flexible cable onto a toroidal body. When the crank is rotated to a certain number of revolutions, the umbrella is fully opened. Further rotation of the crank compresses the spring by 90.711 KF (200 lbs),
This allows the upper end of the umbrella to tilt in a controlled manner. The diameter of the cylinder must be sufficiently small to obtain sufficient mechanical advantage to compress the spring. The present invention requires the crank to be rotated approximately 40 times before the umbrella can be opened.
It would be desirable to provide a tiltable umbrella winder 9 device of the type described above, which allows the winder to be opened with a relatively low number of revolutions of the winder handle and which retains the required mechanical advantages during tilting of the umbrella. It is in.

Another object of the present invention is to provide a backlash braking mechanism that prevents the take-up 9 mechanism from being erroneously or unnecessarily reversed or unwound after the desired male tilt has been achieved. There is a particular thing.

The above-mentioned object of the present invention comprises a first shaft part for winding a first part of the cable which serves to open the umbrella, and a second part for winding a second part of the cable which performs the tilting of the umbrella; The present invention has a winding frame in which the diameter of the first shaft portion is different from that of the second shaft portion, and the umbrella can be opened at a relatively faster speed than the tilting of the umbrella. It can be achieved by using a winding device.

A reel having two diameters is disclosed in U.S. Pat. No. 4,07g, 1
Although it is disclosed in the '85 specification, it is used in a rotating reel and does not have the same structure or function as the winding frame according to the present invention.

In a preferred embodiment of the invention, the winding frame further comprises a mechanism forming a smooth boundary between the first and second shank portions, the mechanism comprising a boundary thread connecting between the outer surfaces of the three shank portions. It is formed from the mountains and has a temperature of ℃. The oni-shaft part has a conical body whose tip tapers gradually from the o-shank part, and the cable is connected to the tapered line of the first shaft part. Furthermore, the winding frame is provided with a radially extending flange on the southern part of each shaft portion to prevent the cable from slipping.

The winding frame is made up of three longitudinal halves and is housed in a cylindrical housing with a hole in the south for inserting the umbrella support.

The pack-crank splitting mechanism according to the present invention is constituted by a cylindrical frame to which a winding frame is attached so as to freely rotate. A first force member 5 is fixed to one end of the shaft for rotation therewith and is rotatably mounted within the housing wall.
Ru. A winding handle is fixed to the shaft of the shaft to drive the shaft, and between the first winding frame and the handle there is a first winding frame which rotates freely in the no-kusing bottle, which is centered at - and faces the Onicum member. A spacer ring is provided. between the spacer ring and the handle.

A two-handed ratchet wheel is provided that freely rotates about the shaft, with pawl members sliding onto the housing and engaging the ratchet teeth to prevent rotation of the ratchet wheel in one direction.

The winding frame is centered on the shaft and includes a cylindrical cam facing the onycam member. The fang 1 and the second cam member include a pair of matching spirals disposed from top to bottom along the same plane perpendicular to the axis of rotation thereof. The distance between the handle and the Onicum member is less than the sum of the lengths of the ratchet wheel, the spacer wheel, the first spool, and the longest portion of the Onicam member.

Umbrella Ky! ! The winding 9 device with the winding speed used performs the winding action of the couple at two different speeds [K, and the mechanical advantages vary accordingly. The spool and cable are housed within a split housing which takes all the stress of the umbrella struts.

In use, the W.xi. chicle is wound in a single wrap so as not to overlap on the four large diameter reel frames located farthest from the second shaft portion. After winding all the way onto the large-diameter shaft section, the couple is smoothly wound from the inner fourth onto the small-diameter section through a boundary thread S of decreasing radius.

The small radius i-axis section then provides an increased mechanical advantage to overcome the spring tension of the tilting mechanism.

By virtue of the spools of 92 different diameters housed within the split housing, the housing acts as a member that fully supports the central force of the umbrella support. Outside the housing, the rotation of the reel is effected by a drive shaft of the conventional type which is attached to the take-up handle with a backlash movement mechanism and which passes through the reel and the reel housing.

The invention will now be described in detail with reference to embodiments illustrated in the accompanying drawings.

The present invention relates to a tiltable heavy-duty winding device of a type in which it is convenient to open the umbrella and tilt the same couple when winding the same couple.

1 member 3 to 8 regarding O Sa figure, Fang Ish figure and Fig. 6
along with a pack rack braking mechanism.

The winding frame 11e installed in the housing z is shown [i].

As explained above, the winding frame is provided with a shaft hole 16 having a circular cross section extending therethrough along its entire length. The winding frame l accommodates the shaft sYt and is freely rotatably mounted thereon. Therefore, the driving force is not directly transmitted from the shaft 3 to the winding frame 1; the driving action of the i0 frame and the braking action of the pack shoes 7 are performed by other members shown in FIG. 5a.

This assembly consists of nine cylindrical cams attached to the cylindrical cam 6, and the cylindrical cam 5 has a cylindrical hole group extending over its entire length and a cylindrical cam part 52b. Hold the cam member lI2.

Collar portion 51 has pin holes for receiving pins 55 . The pin hole is also received within the pin hole of the shaft for positioning the cam cutter 6 on the shaft 3. The collar portion 61 is supported on the outside of the main body member n' of the /S rod, and the cam member sleeve is housed within the wall of the transverse hole 5'.

A spacer ring 7 containing an axial cylindrical bore 71 is also supported on the shaft 3 for free rotation around the shaft 3 and is arranged for free rotation within the transverse bore of the one body segment. . A ratchet wheel 6 having ratchet teeth 61i is disposed on the shaft 3 on the outside of the winding frame/1 screw/g, and the ratchet wheel 6 has a ratchet wheel 6t which can freely rotate around the shaft 3. It is provided with a cylindrical hole 62 having a shape of 0°C. The end block of the pawl member 8 engages with the two-check teeth 61, so that the six two-check wheels rotate only in the clockwise direction.
In order to do this, it is rotatably attached to the main body part n of the housing via the hole and fixing ^83.

Attached to the other end of the shaft 3 is a winding handle 4 having a cylindrical hole l and a bottle hole 44 for receiving a bottle 45t.

The pin engages with the pin hole 31 of the shaft 3.

The handle 4 is fixed thereon. The handle 4 is designed with a main body portion 41 and a grip portion width of 5K so that a hand can be wrapped around the handle.

Cam parts 19g, 194 and cam cutter on winding frame l
The cam portion 52g, mA on 6 is a one-way shoulder cam composed of a pair of spiral bodies formed from the top to the bottom along the same plane perpendicular to the axis of rotation.

As a result of the apparatus being assembled as shown in FIG. 6, the cams engage each other to transmit force from the handle to the bobbin and to provide a brake action. As shown in the figure, the distance between the handle fixed with a bottle in the shaft hole 31 and n is such that the distance between the handle 4 and the inner shoulder of the collar portion 51 is the distance between the Pf etching wheel 6, the spacer wheel 1, and the winding frame 1tnx. The length is set to be shorter than the sum of the lengths of the shaft portion and the highest i cam distance of the cam member and the cam member.

When in use, in order to open the umbrella, when / / dollar 4 is rotated clockwise, the weight of the umbrella frame and cover JtK acting through the lifting cable C causes the winding frame l to be initially at rest. The cam member trout and eye are separated from each other. Cam color! I! Since it is directly connected to the fi shaft 3, rotation of the cam collar causes the cam surface of the cam member to slide on the helical cam surface of the cam member 19 of the winding frame l, thereby pressing the winding frame.

When the winding frame is strongly pressed toward the spacer wheel 7, the spacer wheel 1 presses the two-handed wheel 6 and the handle 4, causing the entire assembly to rotate in degrees Celsius due to static friction. As a result, the driving force is transmitted from the handle 4 through the shaft 3 at the cam collar 81, and the freely rotatable winding frame 1.9-chip wheel 6 and spacer wheel 7 are driven by static friction. When clockwise rotation is stopped, the temporarily locked and pulled drive-brake assembly locks onto ratchet tooth 6.
The locking action of the pawl member 8 on 1 prevents rotation in the 1 counterclockwise direction.

In order to unlock the device so that the early cable can be rewound, K.
A predetermined counterclockwise force applied to the handle 4 reverses the cam drying due to the direct drive of the handle 4 through the °C axis s1 against the cam collar 5.

Eliminates static friction effects. I! of the cam member area and the cam surface of the cam member 19 in the counterclockwise direction! # allows the ratchet ring to rotate freely around the shaft 3, thereby making the engagement effect of the pawls ineffective. After that, the umbrella has force A 19a,
62a, ah lj' in the counterclockwise direction by joining the ends of the cam members that can be directly engaged.

As shown in FIG. 6, the cable C is wound from the rightmost side of the winding frame l without overlapping. The 1-9 cable portions on the shaft portion n correspond to the cable portions that function to open the umbrella. - The cable is then passed through the smooth border formed by the threaded part 1G into the small shaft section 1jKJI, which details are then tilted and attached to a section t* of 5 couples O. Thus, over 5K, the mechanical advantage conferred by the shaft section 11K is retained;
The opening speed of the umbrella is given by the large diameter shaft portion H.

The above description has been described as an example of the present invention and is not intended to limit the scope of the present invention, and many modifications and changes can be made without departing from the spirit and scope of the present invention.
