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

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
