Total Claims: 8
Claim 1
Independent Claim
247 words
Telescopic device comprising a plurality of elongated members disposed one within the other in a fully telescoping retracted condition thereof and including an innermost member, an outermost member and at least one member intermediate thereto, said members being displaceable in longitudinal direction relative to one another in a predetermined sequence, stop means for limiting travel of said members relative to one another, said at least one intermediate member being formed at a wall region located at one end thereof with a recess penetrating therethrough, a locking member disposed in said recess and having a dimension greater than the thickness of said wall region, one of said innermost and outermost members being formed with a depression at the end thereof located, in said fully telescoping retracted position of said members, adjacent the other end of said elongated intermediate members, said locking member, in a extended condition of said intermediate member with respect to said one of said innermost and outermost members, being partly receivable in said depression, a projection extending from the other of said innermost and outermost members, at an end thereof located adjacent to said one end of said intermediate member in said fully telescoping retracted position of said members, said projection at least partly surrounding said locking member, and blocking means located at one side of said projection, and being engageable with said locking member for holding the same in a blocked position located at one side of said wall region of said intermediate member.
Claim 2
Dependent Claim
247 words
Telescopic device comprising a plurality of elongated members disposed one within the other in a fully telescoping retracted condition thereof and including an innermost member, an outermost member and at least one member intermediate thereto, said members being displaceable in longitudinal direction relative to one another in a predetermined sequence, stop means for limiting travel of said members relative to one another, said at least one intermediate member being formed at a wall region located at one end thereof with a recess penetrating therethrough, a locking member disposed in said recess and having a dimension greater than the thickness of said wall region, one of said innermost and outermost members being formed with a depression at the end thereof located, in said fully telescoping retracted position of said members, adjacent the other end of said elongated intermediate members, said locking member, in a extended condition of said intermediate member with respect to said one of said innermost and outermost members, being partly receivable in said depression, a projection extending from the other of said innermost and outermost members, at an end thereof located adjacent to said one end of said intermediate member in said fully telescoping retracted position of said members, said projection at least partly surrounding said locking member, and blocking means located at one side of said projection, and being engageable with said locking member for holding the same in a blocked position located at one side of said wall region of said intermediate member.
Claim 3
Dependent Claim
29 words
Telescopic device according to claim 1 including a plurality of locking members distributed about the periphery of said telescoping members in a plane transverse to the longitudinal direction thereof.
Claim 4
Dependent Claim
25 words
Telescopic device according to claim 1 wherein said locking member has a dimension at least about 30% greater than the thickness of said wall region.
Claim 5
Dependent Claim
28 words
Telescopic device according to claim 1 wherein said innermost, outermost and intermediate members are formed of an axially symmetrical assembly of cylindrical tubes encased one within the other.
Claim 6
Dependent Claim
35 words
Telescopic device according to claim 1 including guide means for preventing relative rotation of said tubes and said locking member, said recess and said depression being alignable in a given extended condition of said tubes.
Claim 7
Dependent Claim
21 words
Telescopic device according to claim 1 wherein said depression is a bore having a smaller diameter than that of said recess.
Claim 8
Dependent Claim
13 words
Telescopic device according to claim 1 wherein said locking member is a ball.
