Abstract

A holder is provided. The holder includes a body and a plurality of fingers received by the body. Each of the plurality of fingers are operable to be translatable within the body to modify the configuration of the fingers. The fingers are operable to be reconfigured to correspond with a drop unit such that the drop unit is held in a desired orientation between the fingers and a drop leaf of a drop tester.

Claims (31)

1. A holder comprising:

a body;

a plurality of fingers received by the body,

wherein each of the plurality of fingers operable to be translatable within the body to modify the configuration of the fingers;

wherein the fingers are operable to be reconfigured to correspond with a drop unit such that the drop unit is held in a desired orientation between the fingers and a drop leaf of a drop tester.

2. The holder of claim 1 , wherein the fingers are operable to be reconfigured to correspond with and hold a corner and/or edge of the drop unit.

3. The holder of claim 1 , further comprising a locking mechanism; wherein when the locking mechanism is in a lock configuration, the configuration of the fingers is maintained in relation to the body; wherein when the locking mechanism is in an unlocked configuration, the fingers are translatable within the body.

4. The holder of claim 3 , wherein the locking mechanism includes a compression plate that is operable to compress against the fingers to transition the locking mechanism to the lock configuration.

5. The holder of claim 4 , wherein the locking mechanism includes one or more compression screws operable to be tightened to press against the compression plate to transition the locking mechanism to the lock configuration.

6. The holder of claim 3 , further including a retainment component operable to keep the fingers within and/or coupled with the body, when the locking mechanism is in the unlocked configuration.

7. The holder of claim 1 , wherein the body forms a plurality of finger guides that are each operable to receive a corresponding finger of the plurality of fingers.

8. The holder of claim 7 , wherein the plurality of finger guides and the plurality of fingers are shaped such that the fingers are not rotatable when received in the corresponding finger guides.

9. The holder of claim 1 , wherein the body includes a coupling mechanism such that the body is operable to be retrofittedly coupled to a conventional drop tester.

10. The holder of claim 9 , wherein the coupling mechanism includes a shaft holder coupled to the body, wherein the shaft holder is operable to receive a shaft that is coupled to the conventional drop tester.

11. A drop tester comprising:

a drop leaf,

a holder including:

a body;

a plurality of fingers received by the body,

wherein each of the plurality of fingers operable to be translatable within the body to modify the configuration of the fingers;

wherein the fingers are operable to be reconfigured to correspond with a drop unit such that the drop unit is held in a desired orientation between the fingers and the drop leaf;

wherein the drop leaf is operable to move such that the drop unit falls from the drop leaf in the desired orientation.

12. The drop tester of claim 11 , wherein the fingers are operable to be reconfigured to correspond with and hold a corner and/or edge of the drop unit.

13. The drop tester of claim 11 , further comprising a locking mechanism; wherein when the locking mechanism is in a lock configuration, the configuration of the fingers is maintained in relation to the body; wherein when the locking mechanism is in an unlocked configuration, the fingers are translatable within the body.

14. The drop tester of claim 13 , wherein the locking mechanism includes a compression plate that is operable to compress against the fingers to transition the locking mechanism to the lock configuration.

15. The drop tester of claim 14 , wherein the locking mechanism includes one or more compression screws operable to be tightened to press against the compression plate to transition the locking mechanism to the lock configuration.

16. The drop tester of claim 13 , wherein the holder further includes a retainment component operable to keep the fingers within and/or coupled with the body, when the locking mechanism is in the unlocked configuration.

17. The drop tester of claim 11 , wherein the body forms a plurality of finger guides that are each operable to receive a corresponding finger of the plurality of fingers.

18. The drop tester of claim 17 , wherein the plurality of finger guides and the plurality of fingers are shaped such that the fingers are not rotatable when received in the corresponding finger guides.

19. The drop tester of claim 11 , wherein the body includes a coupling mechanism such that the body is operable to be coupled to the drop tester, wherein the coupling mechanism includes a shaft holder coupled to the body, wherein the shaft holder is operable to receive a shaft that is coupled to the drop tester.

20. The drop tester of claim 11 , further comprising a hoist operable to raise and/or lower the holder and/or the drop leaf.
