Abstract

Abstract An improvement in a device for transporting and storing yarn bobbin tubes arranged on a substantially horizontal pallet. A number of holding elements are mounted on the pallet which have top and bottom protuberances and depressions for centering and supporting the lower and upper end of the bobbin tubes so that a number of pallets having intermediately mounted yarn bobbin can be stacked one upon the other. Each holding element is composed of two holding element parts made of an injectable or pressable plastic material and arranged one above the pallet and one below the pallet. One holding element part is made of a resilient plastic material and has a substantially cylindrical, radially and resiliently compressible shank provided with an inner lock thereon. The other holding element part has a cylindrical opening thereon to receive the shank, the diameter of the opening is less than the maximum diameter of the shank so that the two holding element parts can be pressed together, the shank having the radial compression factor passing through the opening and snapping into engagement with the other holding element part through the aforesaid inner lock.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 182 words
In a device for transporting and storing yarn bobbins having bobbin tubes and having a substantially horizontally arranged pallet and a number of holding elements mounted on the said pallet, which elements have at the top and bottom protuberances and depressions for centering and supporting always the lower and upper end of the bobbin tube, such that a number of pallets with intermediately mounted yarn bobbins can be stacked one upon the other, the improvement comprising each holding element being composed of two holding element parts of injectable or pressable plastic material being arranged one above and one below the pallet, one holding element part being made of a resilient plastic material and having a substantially cylindrical, radially and resiliently compressible shank provided with interlocking means, the other holding element part having a cylindrical opening for the said shank, whose diameter is less than the maximum diameter of shank, such that the two holding element parts can be pressed together in a snap fastener fashion, the shank with radial compression passing through the opening and there snapping in with its interlocking means.
Claim 2
Dependent Claim 182 words
In a device for transporting and storing yarn bobbins having bobbin tubes and having a substantially horizontally arranged pallet and a number of holding elements mounted on the said pallet, which elements have at the top and bottom protuberances and depressions for centering and supporting always the lower and upper end of the bobbin tube, such that a number of pallets with intermediately mounted yarn bobbins can be stacked one upon the other, the improvement comprising each holding element being composed of two holding element parts of injectable or pressable plastic material being arranged one above and one below the pallet, one holding element part being made of a resilient plastic material and having a substantially cylindrical, radially and resiliently compressible shank provided with interlocking means, the other holding element part having a cylindrical opening for the said shank, whose diameter is less than the maximum diameter of shank, such that the two holding element parts can be pressed together in a snap fastener fashion, the shank with radial compression passing through the opening and there snapping in with its interlocking means.
Claim 3
Dependent Claim 13 words
The improvement according to claim 1, wherein the shank has axially extending slots.
Claim 4
Dependent Claim 11 words
The improvement according to claim 2, wherein the shank is hollow.
Claim 5
Dependent Claim 22 words
The improvement according to claim 2, wherein the interlocking means consist of a flange provided on the free end of the shank.
Claim 6
Dependent Claim 28 words
The improvement according to claim 4, wherein a shoulder is provided on the other holding element part behind the opening, the flange snapping in behind the said shoulder.
Claim 7
Dependent Claim 32 words
The improvement according to claim 4, wherein at least one of tHe flange and the opening on the edges, which first come into contact on being pressed together, are rounded or chamfered.
Claim 8
Dependent Claim 24 words
The improvement according to claim 1, wherein the one holding element part has a supporting flange adjacent the shank for support on the pallet.
Claim 9
Dependent Claim 69 words
The improvement according to claim 1, including a pallet composed of a rectangular frame and intersecting rods arranged therein, wherein four axial slots in the shank are arranged always offset by 90* relative to each other, extend to the supporting flange and have a width which is at least as large as the diameter of the rods so that the intersection of two rods is arranged inside the shank.
Claim 10
Dependent Claim 64 words
The improvement according to claim 8, wherein on the end of the other holding element part facing the flange of the one holding element part, four slots always offset by 90* relative to each other are provided, whose width is at least as large as the diameter of the rods and whose length is approximately twice as large as the diameter of a rod.
Claim 11
Dependent Claim 17 words
The improvement according to claim 1, wherein the holding element parts are made of high impact-resistant polystyrene.
Claim 12
Dependent Claim 20 words
The improvement according to claim 1, wherein the shank is provided on the holding element part arranged under the pallet.
Claim 13
Dependent Claim 99 words
The improvement according to claim 1, wherein the holding element parts are widened in stepped fashion towards the pallet, said pallet having intersecting rods, one holding element part having a flange which is somewhat larger in diameter than the flange of the other holding element part and embraces the said latter flange, axial slots being provided in both flanges for the passage of the rods, and the flange of one holding element part being provided with a radially inwardly projecting flange while the flange of the other holding element part has a radially outwardly projecting shoulder as interlocking means.
