Abstract
A caster with a structural improvement includes a wheel holder, a spindle seat, a spindle and two wheels. A through hole of the spindle seat is covered on a spindle housing of the wheel holder with a ring groove of the spindle seat engaged by an annular flange of the spindle housing, further the spindle is inserted into the spindle housing with at least one ring groove of the spindle engaged by at least one circumferential ridge of the spindle housing, and finally axle housings of the wheels are inserted by a wheel axle of the wheel holder with a ring groove of the wheel axle engaged by a circumferential ridge of the axle housings, whereby the wheels can swivel and move. Moreover, the spindle seat can be assembled with wheel holders and wheels of various sizes, thereby reducing the costs of new molds for spindle seats of different sizes.
Description
- 1. Field of the Invention
- This invention relates to a caster with a structural improvement, particularly to one having a spindle seat adapted to be assembled with wheel holders and wheels of various sizes, thereby reducing the costs in producing new molds for spindle seats of different sizes.
- 2. Description of the Prior Art
- Generally speaking, a known conventional caster, as shown in FIG. 1, has an integrally formed caster holder1 provided with a
curved fender 10. Aspindle 11 is disposed at a top of the caster holder 1 and twowheels 12 are combined below thecurved fender 10 of the caster holder 1. However, thecurved fender 10 of the caster holder 1 is only adapted to be assembled with twowheels 12 of a certain fixed size and is unable to be assembled with twowheels 12 of various sizes. Therefore, every time when the twowheels 12 are required with a different size, it is necessary to produce a new mold for the caster holder 1 to meet the required size of the twowheels 12, thus greatly increasing the costs in producing new molds for caster holders 1 of different sizes. - As can be realized from the above description, the shortcomings of the known conventional casters have been presented in the existing prior arts for a long time. Therefore, the present invention is to create a novel and unique construction to increase exchangeability and decrease producing costs.
- The main purpose of the invention is to offer a caster with a structural improvement having a spindle seat adapted to be assembled with wheel holders and wheels of various sizes, thereby reducing the costs in producing new molds for spindle seats of different sizes.
- The main feature of the invention is to provide a caster with a structural improvement mainly including:
- a wheel holder having a wheel axle secured in a proper place thereof and a spindle housing upwards protruded thereon, the wheel axle provided with two ring grooves respectively disposed at both ends thereof, the spindle housing provided with at least one circumferential ridge disposed in an inner wall thereof and an annular flange formed on an outer wall of a top thereof;
- a spindle seat capable of being covered on the spindle housing of the wheel holder and having a channel and a through hole, the through hole formed in a center of the spindle seat and provided with a ring groove disposed in an inner wall thereof;
- a spindle capable of being inserted into the spindle housing of the wheel holder and having at least one ring groove; and,
- two wheels capable of being respectively combined with both ends of the wheel axle of the wheel holder and each having an axle housing disposed in a proper place thereof, each of the axle housings provided with a circumferential ridge disposed in an inner wall thereof.
- This invention will be better understood by referring to the accompanying drawings, wherein:
- FIG. 1 is a perspective view of a known conventional caster;
- FIG. 2 is an exploded perspective view of a caster with a structural improvement in the present invention; and,
- FIG. 3 is a perspective view of the caster with a structural improvement in the present invention.
- A preferred embodiment of a caster with a structural improvement in the present invention, as shown in FIG. 2, mainly includes a
wheel holder 2, aspindle seat 3, aspindle 4, and twowheels 5. - The
wheel holder 2 integrally formed in a shape approximated to a semi-circle has awheel axle 20 secured in a proper place thereof, and a spindle housing 22 upwards protruded at one end thereof. Thewheel axle 20 is provided with tworing grooves 200 respectively disposed at both ends thereof, and a plurality of reinforcedribs 21 disposed at its periphery. Thespindle housing 22 is provided with at least onecircumferential ridge 220 disposed in an inner wall thereof and anannular flange 221 formed on an outer wall of a top thereof. A bottom of thespindle housing 22 is connected with some of the plurality of reinforcedribs 21. - The
spindle seat 3 capable of being covered on thespindle housing 22 of thewheel holder 2 is integrally formed with a top in a shape of circle and with a portion adjacent to the top in a shape of an oblique curved surface whose lower portion is narrowed down. Achannel 30 extends across the oblique curved surface of thespindle seat 3. A throughhole 31 is formed in a center of thespindle seat 3 and extends through thechannel 30 of thespindle seat 3. The throughhole 31 has aring groove 310 disposed in an inner wall thereof. - The
spindle 4 capable of being inserted into thespindle housing 22 of thewheel holder 2 has at least onering groove 40 disposed at one end thereof. - The two
wheels 5 are capable of being respectively combined with both ends of thewheel axle 20 of thewheel holder 2 and each of which is integrally formed and has anaxle housing 50 disposed in a proper place of an inner side thereof. Each of theaxle housings 50 is provided with acircumferential ridge 500 disposed in an inner wall thereof. A plurality of reinforcedribs 501 are disposed at the periphery of theaxle housing 50 and connected with theaxle housing 50. - In assembling, referring to FIGS. 2 and 3, firstly align the through
hole 31 of thespindle seat 3 to thespindle housing 22 of thewheel holder 2, and then correspondingly cover the throughhole 31 of thespindle seat 3 on thespindle housing 22 of thewheel holder 2 with thering groove 310 of the throughhole 31 of thespindle seat 3 engaged by theannular flange 221 of thespindle housing 22 of thewheel holder 2 and with thechannel 30 of thespindle seat 3 engaged by one end of an outer wall of thewheel holder 2 in position. Secondly, correspondingly insert thespindle 4 into thespindle housing 22 of thewheel holder 2 with the at least onering groove 40 of thespindle 4 engaged by the at least onecircumferential ridge 220 of thespindle housing 22 of thewheel holder 2. Finally, insert both ends of thewheel axle 20 of thewheel holder 2 respectively into theaxle housings 50 of the twowheels 5 with thering grooves 200 of both ends of thewheel axle 20 of thewheel holder 2 respectively engaged by thecircumferential ridges 500 of theaxle housings 50 of the twowheels 5, by which the caster with a structural improvement of the present invention is assembled all together. - Moreover, the
spindle seat 3 in the preferred embodiment is adapted to be assembled withwheel holders 2 andwheels 5 of various sizes, thereby reducing the costs in producing new molds forspindle seats 3 of different sizes. - While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
