Abstract
A sunshade frame has an upper support member secured to a top end of a shank; the ribs of the frame are each pivoted to a corresponding one of longitudinal trenches of the upper support member from an inner end. The frame has a lower support member movably connected to the shank, and spreader rods pivoted to the lower support member from inner ends; the spreader rods are each pivoted to a corresponding one of the ribs by means of a pivotal pin from an outer end with an elastic member disposed in between to prevent the connection from getting loose in case the pivotal pin is too long for the width of same. The upper, and the lower support members have an upper, and a lower confining rim respectively to prevent the ribs and the spreader rods from pivoting beyond same to a wrong position.
Description
- The present invention relates to a sunshade frame, and particularly to one which can remain in good shape even under strong winds.
- Referring to FIG. 6, a conventional sunshade frame includes a
shank 10, anupper support member 20,ribs 40, alower support member 30 andspreader rods 60. - The
upper support member 20 is secured to a top end of theshank 10, and has longitudinal receivingtrenches 201 spaced apart on an outer side; atransverse trench 202 is formed, intersecting with thelongitudinal receiving trenches 201, on an intermediate portion of the outer side. Theribs 40 are each pivoted to a corresponding one of the receivingtrenches 20 from an inner end portion by means of a locatingmember 50, which is secured in thetransverse trench 202, and passed through the inner end portions of theribs 40. - The
lower support member 30 is movably connected to theshank 10, and also has longitudinal receiving trenches 301 and atransverse trench 302 like theupper support member 20. Thespreader rods 60 are pivoted to the receiving trenches 301 from inner end portion by means of another locatingmember 50 secured in thetransverse trench 302 and passed through the spreader rod inner end portion. - The outer ends of the
spreader rods 60 are each pivoted to a corresponding one of theribs 40. Thus, the sunshade can be spread for use by means of moving thelower support member 30 to a suitable position. - However, the sunshade with the conventional sunshade frame is found to have a drawback that the canopy and the
ribs 40 can be easily blown upwards to a wrong position by strong winds, and consequently the frame would get damaged. - If the ribs and the spreader rods are made of bamboos, there will be a difficulty in manufacturing the sunshade frame because there would be differences between the diameters of the bamboo stems used as the ribs and the spreader rods, it is impossible to prepare all pivotal pins for pivoting the spreader rods to the ribs with a suitable length; consequently, washers have to be disposed between the ribs and the spreader rods when the pivotal pins are too long otherwise the connection would be too loose.
- Therefore, it is a main object of the present invention to provide a sunshade frame which can remain in good shape under strong winds.
- And, it is another object of the present invention to provide a sunshade frame which can be manufactured relatively easily even when the ribs and the spreader rods are made of bamboo stems.
- The sunshade frame of the present invention includes an upper support member, a shank, ribs, spreader rods and a lower support member.
- The upper support member is secured to a top end of the shank, and has several longitudinal receiving trenches spaced apart on an outer side each having a corresponding one of the ribs pivoted thereto. The upper support member further has a confining rim on upper ends of the longitudinal trenches to prevent the ribs from pivoting up beyond same to a wrong position.
- The lower support member is movably connected to the shank, and has a confining rim on a lower side to prevent the spreader rods pivoted thereto from pivoting down beyond same to a wrong position. So, the frame can remain in good shape with the confining rims even in strong winds.
- Furthermore, an elastic member is disposed between each of the ribs and the corresponding one of the spreader rods in pivotal connection such that the connection won't get loose in case the pin provided for the pivotal connection is too long. The manufacture doesn't have to worry about the length of pin when the ribs and the spreader rods are made of bamboo stems without uniform width.
- This invention will be better understood by referring to the accompanying drawings, wherein:
- FIG. 1 is a view of the sunshade frame according to the present invention.
- FIG. 2 is a fragmentary exploded perspective view of the sunshade frame according to the present invention.
- FIG. 3 is a fragmentary view of the sunshade frame in FIG. 1.
- FIG. 4 is a fragmentary side view of a rib and the associated spreader rod of the sunshade frame in FIG. 2.
- FIG. 5 is a cross-sectional view of the rib and the spreader rod of FIG. 4.
- FIG. 6 is a fragmentary view of the conventional sunshade frame in the Background.
- Referring to FIGS. 1, 2 and3, a sunshade frame of the present invention includes a
shank 1, anupper support member 2, alower support member 3,ribs 4, locatingmembers 5 andspreader rods 6. - The
upper support member 2 is secured to a top end of theshank 1, and has aconfining rim 23 on an upper side. Theupper support member 2 further has longitudinal receivingtrenches 21 spaced apart on an outer side under theconfining rim 23, and has atransverse trench 22 formed on an intermediate portion of the outer side, intersecting with thelongitudinal receiving trenches 21. - The
ribs 4 are pivoted to a locatingmember 5 from inner end portions; the locatingmember 5 is passed around, and secured in, thetransverse trench 22 with the inner end portions of theribs 4 each being movably received in a corresponding one of the longitudinal receivingtrenches 21. - The
lower support member 3 is movably connected to the shank, and has longitudinal receivingtrenches 31 spaced apart on an outer side, and has atransverse trench 32 intersecting with intermediate portions of the receivingtrenches 31. Thelower support member 3 further has aconfining rim 33 formed on lower ends of the receivingtrenches 31. - The
spreader rods 6 are pivoted to a second locatingmember 5 from inner end portions, and the locatingmember 5 is passed around, and secured in, thetransverse trench 32 with the spreader rod inner end portions each being movably received in a corresponding one of the longitudinal receivingtrenches 31. Thus, thespreader rods 6 can pivot on thelower support member 3 as theribs 4 can pivot on theupper support member 2. - The
spreader rods 6 are each pivoted to a corresponding one of theribs 4 from an outer end by means of apivotal pin 7 with anelastic member 8 being disposed between thespreader rod 6 and the rib 4 (FIG. 5). - When the sunshade with the frame is spread for use, the
confining rim 23 of theupper support member 2 will prevent theribs 4 from pivoting up beyond a suitable position, and thespreader rods 6 also can be held in a suitable position by means of theconfining rim 33 of thelower support member 3. - Moreover, because of the
elastic members 8, the manufactures don't have to worry about the length of thepivotal pins 7, which might be too long for some of theribs 4 and thespreader rods 6 when they are made of bamboo stems, for which it is not possible to have an uniform width, i.e. in case thepivotal pins 7 are too long, theelastic members 8 disposed between the ribs and thespreader rods 6 can prevent the connection from getting loose. - When the
ribs 4 and thespreader rods 6 are made of bamboo stems, two ends of same are provided with plugs to prevent water from flowing in. - From the above description, the sunshade frame of the present invention can be known to have desirable features as follows:
- 1. The confining rims of the upper and
lower support members ribs 4 and thespreader rods 6 from moving to wrong position to get damaged under strong winds. - 2. The connection between the ribs and the spreader rods won't be loose when the pivotal pins connecting same are too long.
