Screw strip
A screw strip for holding a plurality of screws is flexible, and includes a plurality of interconnected screw-holding strip portions. Each of the screw-holding strip portions includes an annular planar top wall and a plurality of pressed and spaced-apart holding tongues. The holding tongues extend integrally, downwardly and inwardly from an inner periphery of the top wall so as to define a screw-clamping space thereamong, which clamps a respective one of the screws therewithin.
This is a Continuation-in-Part (CIP) of U.S. patent application Ser. No. 10/886,840, filed on Jul. 8, 2004.
BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to a screw holder, and more particularly to a screw strip for holding a plurality of screws thereon.
2. Description of the Related Art
Referring to
Referring to
The object of this invention is to provide a screw strip that can be manufactured at a relatively low cost.
According to this invention, a screw strip for holding a plurality of screws is provided. Each of the screws has a shank and a head. The screw strip is flexible, and includes a plurality of interconnected screw-holding strip portions, each of which comprises:
an annular planar top wall having a circular inner periphery, the inner periphery defining a hole that is sized so as to prevent passage of the head of a respective one of the screws therethrough; and
a plurality of pressed and spaced-apart holding tongues extending integrally, downwardly and inwardly from the inner periphery of the planar top wall so as to define a screw-clamping space thereamong, which is adapted to clamp the respective one of the screws therewithin.
Since the holding tongues are formed by a pressing process, the screw strip can be easily mass-produced so as to reduce the manufacturing costs of the screw strip.
BRIEF DESCRIPTION OF THE DRAWINGSThese and other features and advantages of this invention will become apparent in the following detailed description of the preferred embodiments of this invention, with reference to the accompanying drawings, in which:
Before the present invention is described in greater detail in connection with the preferred embodiments, it should be noted that similar elements and structures are designated by like reference numerals throughout the entire disclosure.
Referring to
The top wall 61 has a circular inner periphery 611 defining a hole that is sized so as to prevent passage of the head 52 of the screw 5 therethrough. The holding tongues 63 extend integrally, downwardly and inwardly from the inner periphery 611 of the top wall 61 along a curved path to define a screw-clamping space 64 thereamong. The screw-clamping space 64 is adapted to clamp the screw 5 therewithin, and has a diameter that reduces downwardly. With the slits 62 formed in the screw-holding strip portions 6, the screw strip of this invention is suitable for holding the screws 5 of different sizes.
It is noted that the screw strip of this invention is formed by extrusion using a composite material comprised of a plastic material and paper pulp, and optionally sawdust, and is subsequently punched and pressed to form the holding tongues 63 and to acquire a desired measure of flexibility. As a result, the screw strip of this invention can be easily mass-produced.
The number of the slits 62 in each of the screw-holding strip portions 6 can be varied, as shown in FIGS. 12 to 19.
With this invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is therefore intended that this invention be limited only as indicated by the appended claims.
Claims
1. A screw strip for holding a plurality of screws, each of the screws having a shank and a head, said screw strip being flexible and including a plurality of interconnected screw-holding strip portions, each of which comprises:
- an annular planar top wall having a circular inner periphery, said inner periphery defining a hole that is sized so as to prevent passage of the head of a respective one of the screws therethrough; and
- a plurality of pressed and spaced-apart holding tongues extending integrally, downwardly and inwardly from said inner periphery of said planar top wall so as to define a screw-clamping space thereamong, which is adapted to clamp the respective one of the screws therewithin.
2. The screw strip as claimed in claim 1, wherein each of said holding tongues extends from said inner periphery of said top wall along a curved path, said screw-clamping space having a diameter that reduces downwardly.
3. The screw strip as claimed in claim 1, wherein said screw-clamping space is frustoconical, and has a diameter that reduces downwardly.
4. The screw strip as claimed in claim 1, wherein said screw-clamping space includes:
- a cylindrical larger-diameter top end portion proximate to said top wall;
- a cylindrical smaller-diameter bottom end portion distal from said top wall and having a diameter smaller than that of said larger-diameter top end portion; and
- a frustoconical intermediate portion having a top end connected to a bottom end of said larger-diameter top end portion, and a bottom end connected to a top end of said smaller-diameter bottom end portion.
5. The screw strip as claimed in claim 1, wherein said screw-clamping space includes:
- a frustoconical top end portion proximate to said top wall and having a downwardly increasing diameter;
- a cylindrical bottom end portion distal from said top wall and having a diameter smaller than a minimum diameter of said top end portion; and
- a frustoconical intermediate portion having a top end connected to a bottom end of said top end portion, and a bottom end connected to a top end of said bottom end portion.
6. The screw strip as claimed in claim 1, wherein each of said screw-clamping spaces has a central line, any two adjacent ones of said holding tongues defining a slit therebetween, said slits in each of said screw-holding strip portions extending radially and outwardly from said central line toward said inner periphery of said top wall.
7. The screw strip as claimed in claim 1, wherein said holding tongues of each of said screw-holding strip portions define cooperatively a circular opening thereamong, any two adjacent ones of said holding tongues defining a slit therebetween, each of said slits extending from a corresponding one of said circular openings toward said inner periphery of a corresponding one of said top walls along a tangent direction of the corresponding one of said circular openings.
