DETAILED DESCRIPTION

[0012] Referring to Fig. 1, a glove 10 includes a glove body 12 in a shape of a hand (e.g., shaped to receive a hand therein) and having a palm side 14 and a dorsal side 16 Date Regue/Date Received 2023-01-26 opposite the palm side. A protective structure 20 is located on the dorsal side and is formed by a thermoplastic rubber element 22 secured on the dorsal side. The thermoplastic rubber element 22 includes a base segment 22a and a plurality of elongated finger segments 22b extending from the base segment. The base segment 22a is located across a base knuckle region of the dorsal side 16 and each finger segment 22b extends along a respective finger region of the dorsal side to a top knuckle region of the finger segment.

[0013] Each finger segment 22b includes a plurality of through openings 24 through which a material 26 forming the glove body is exposed. The plurality of through openings 24 of each finger segment are spaced apart along a length of the finger segment.
At least one through opening, here multiple through openings, of each finger segment is/are bounded, at least in part, by a thermoplastic boundary segment 22c and each thermoplastic boundary segment 22c is bounded, at least in part, by a surrounding thermoplastic main segment 22d. The combination of the thermoplastic boundary segments 22c and surrounding thermoplastic main segments 22d provides for a two-stage impact configuration. In particular, each thermoplastic boundary segment 22c is (i) shaped to be more flexible than the surrounding thermoplastic main segment 22d and/or (ii) dimensioned to be more flexible than the surrounding thermoplastic main segment and/or (iii) comprised of a material that is more flexible than a material of the surrounding thermoplastic main segment.

[0014] The protective structure 20 is a separate unit that is connected to the material 26 of the dorsal side 16 of the glove body, such as by stitching or adhesive.

[0015] Each thermoplastic boundary segment 22c has at least one portion 30 that extends to a height that is higher than a height of all immediately adjacent portions of the surrounding thermoplastic main segment 22d, where each height is measured in a direction perpendicularly away from the dorsal side of the glove (e.g., in a direction out of the page in Fig. 1).

[0016] For each thermoplastic boundary segment, a recess 32 is formed in the thermoplastic rubber element at least between an upper portion of the thermoplastic boundary segment 22c and an upper portion of the surrounding thermoplastic main segment 22d. The surrounding thermoplastic main segment 22d has a main thickness TM, and the recess 30 extends downward a depth dl for at least 40% of the main thickness (e.g., at least 50% of the main thickness). The recess provides increased flexibility of the thermoplastic boundary segment 22c relative to the thermoplastic main segment 22d.

Date Regue/Date Received 2023-01-26

[0017] In embodiment, a lower portion of each thermoplastic boundary segment 22c is bonded to a lower portion of the surrounding thermoplastic main segment 22. More specifically, the lower portion of each thermoplastic boundary segment 22c may be bonded to the lower portion of the surrounding thermoplastic main segment 22d by co-molding.
The materials used for each thermoplastic boundary segment 22c and the surrounding thermoplastic main segments 22d may be identical. However, in other embodiments, the composition of the thermoplastic boundary segments 22c may be different than that of the thermoplastic main segments 22d, to enhance the differential flexibility of the thermoplastic boundary segments.

[0018] Here, the higher portions 30 are configured as a peak formed by a first upwardly angled top edge 30a and a second upwardly angled top edge 30b, providing a generally triangular-shape in side view. In addition, the peaks are further formed by a first side wall 30c and a second side wall 30d that angle toward each other when moving upward to the peak. This configuration provides for increasing flexibility of the portions 30 along the height of the portions 30. Fig. 4A shows a cross-section along A-A of Fig. 4, showing the bonding regions 31 between the boundary segment 22c and the main segment 22d.

[0019] Thus, the portions 30 form multiple sections that are raised relative to the surrounding thermoplastic main segment 22d such that a planar object moving toward the dorsal side of the glove will impact one or more of such raised sections prior to impacting the surrounding thermoplastic main segment, per Fig. 6, providing the two-stage impact feature. Fig. 7 shows exemplary deflection of a portion 30 during an initial impact.
Boundary segments 22c (stage 1) are thus configured as the first point of contact to absorb light impact and abrasions, protecting the integrity of main segments 22d (e.g., many nicks and abrasions experienced throughout that day, so as to not cause premature wear of portion 22d). Boundary segments 22c (stage 1) are also configured to absorb some initial impact, working jointly with segment 22d, to achieve an overall impact performance level (e.g., such as ANSI Level 2).

[0020] In the illustrated embodiment, a perimeter of each through opening 24 is Y-shaped. This shape has been found particularly advantageous to facilitate glove flex (e.g., when a user makes a fist). However, other opening shapes are possible.

[0021] As seen in Figs. 1 and 2, the base segment 22a also include multiple through openings with thermoplastic boundary segments and surrounding thermoplastic main Date Regue/Date Received 2023-01-26 segments similar to that described above for the finger segments. In addition, the thumb portion of the glove may include a separate thermoplastic protective structure with similar openings.

[0022] It is to be clearly understood that the above description is intended by way of illustration and example only, is not intended to be taken by way of limitation, and that other changes and modifications are possible.
