Abstract
Abstract A web-shaped longitudinal connecting link for tire chains with a circumferentially closed transverse first passage and with a second transverse passage communicating with the outside through an opening while a pin supported by the link is selectively movable in said opening to thereby reduce the free inner cross section of the opening so as to prevent a link suspended in the second passage from leaving the same.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
174 words
A connecting link for tire chains having one longitudinal surface forming the running surface of the connecting link and having another longitudinal surface forming the tire-engaging surface of said connecting link, said connecting link being provided with first passages therethrough having their axes extending in a direction transverse to the longitudinal direction of said connecting link, said connecting link also having a second passage extending from one of said longitudinal surfaces to one of said first passages and being so dimensioned as to permit the introduction of a chain link therethrough into the respective second passage communicating therewith, and closure pin means with opposite ends engaged as displaceably supported by said connecting link and operable selectively to be moved into and out of said second passage to respectively reduce its free cross section so as to prevent a chain link previously introduced through said second passage into said first passage communicating therewith from leaving the latter and permitting the chain link introduced into said last-mentioned first passage to be withdrawn through said second passage.
Claim 2
Dependent Claim
174 words
A connecting link for tire chains having one longitudinal surface forming the running surface of the connecting link and having another longitudinal surface forming the tire-engaging surface of said connecting link, said connecting link being provided with first passages therethrough having their axes extending in a direction transverse to the longitudinal direction of said connecting link, said connecting link also having a second passage extending from one of said longitudinal surfaces to one of said first passages and being so dimensioned as to permit the introduction of a chain link therethrough into the respective second passage communicating therewith, and closure pin means with opposite ends engaged as displaceably supported by said connecting link and operable selectively to be moved into and out of said second passage to respectively reduce its free cross section so as to prevent a chain link previously introduced through said second passage into said first passage communicating therewith from leaving the latter and permitting the chain link introduced into said last-mentioned first passage to be withdrawn through said second passage.
Claim 3
Dependent Claim
48 words
A connecting link according to claim 1, in which said second passage is partially defined by a transverse wall portion of said connecting link which wall portion directly engages the closure pin means when the latter extends into said first passage for positively supporting said closure pin means.
Claim 4
Dependent Claim
45 words
A connecting link according to claim 2, which is provided with a bore for receiving and supporting said closure pin means, and in which said closure pin means engaging wall portion is inclined with regard to the extension of the longitudinal axis of said bore.
Claim 5
Dependent Claim
34 words
A connecting link according to claim 3, in which the extension of the axis of said bore and the closure pin means engaging wall portion define with each other an angle of about 10*.
Claim 6
Dependent Claim
29 words
A connecting link according to claim 1, in which the longitudinal axis of said closure pin means is located substantially in the longitudinal central plane of said connecting link.
Claim 7
Dependent Claim
20 words
A connecting link according to claim 1, in which said closure pin means extends substantially transverse to the running surface.
Claim 8
Dependent Claim
21 words
A connecting link according to claim 1, in which said closure pin means extends perpendicular with regard to said running surface.
Claim 9
Dependent Claim
39 words
A connecting link according to claim 1, which is web-shaped and has at least one side designed so as to form a hook, and in which said closure pin means is movAble within the opening defined by said hook.
Claim 10
Dependent Claim
50 words
A connecting link according to claim 8, in which one of said first passages is circumferentially completely closed, and in which said closure pin means engaging wall portion is formed by that portion of the web which is located opposite said hook and adjacent said circumferentially completely closed first passage.
Claim 11
Dependent Claim
30 words
A connecting link according to claim 1, in which the bore receiving said closure pin means extends through said running surface approximately in the center portion of the length thereof.
Claim 12
Dependent Claim
23 words
A connecting link according to claim 1, in which portions of said link support said closure pin means over nearly its entire length.
Claim 13
Dependent Claim
36 words
A connecting link according to claim 1, in which the bore for receiving said closure pin means extends all the way through from said running surface into said first passage which communicates with said second passage.
Claim 14
Dependent Claim
47 words
A connecting link according to claim 1, in which the cross-sectional contour of said link is double trapezoidal with the narrower sides of the trapezoids joined to each other and with the lateral surfaces tapering toward each other from the running surface and the tire-engaging surface respectively.
Claim 15
Dependent Claim
22 words
A connecting link according to claim 3, in which that portion of the link which contains the bore has the greatest width.
