Abstract
Abstract A measuring device having a scale which is movable along a straight line characterized by the movable scale being disposed within a housing and connected through a carrier part fixed on one end of the scale to a sliding part disposed in parallel relation with the scale and movable therewith along a path parallel to the path of movement of the scale, the sliding part being surrounded by a seal carried by the housing outside the sliding area of the carrier part and a point of applying a stress to the sliding part, the latter being a member projecting from the housing and connected to the sliding part for effecting movement of the sliding part from outside the housing, whereby a measuring device of very short length relative to the length of the scale is provided which is sealed in a substantially perfect manner against dampness and dirt.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
231 words
A measuring device comprising: a housing; an elongate scale slidable within said housing for movement along a longitudinal path between first and second end positions; a sliding part disposed in parallel relation with and closely adjacent to said scale, being slidable along a path parallel to said longitudinal sliding path of said scale between corresponding first and second end positions; means disposed within said housing connecting said scale and said sliding part at respective one ends thereof for effecting simultaneous sliding movements of said scale and said sliding part in the same direction along said longitudinal sliding paths; a seal secured within said housing and sealingly engaging the periphery of said sliding part while permitting sliding movement of said sliding part through said seal, said seal engaging said sliding part adjacent the other end thereof when said sliding part is disposed in said first end position; a force receiving member projecting from said housing and being connected to said sliding part at the other end thereof for effecting sliding movement thereof from outside the housing; and said sliding part in said first end position of its sliding path being substantially disposed within said housing, and in the course of sliding toward said second end position of its sliding path upon application of a force to said force receiving member being progressively projected through said seal from the confines of said housing.
Claim 2
Dependent Claim
231 words
A measuring device comprising: a housing; an elongate scale slidable within said housing for movement along a longitudinal path between first and second end positions; a sliding part disposed in parallel relation with and closely adjacent to said scale, being slidable along a path parallel to said longitudinal sliding path of said scale between corresponding first and second end positions; means disposed within said housing connecting said scale and said sliding part at respective one ends thereof for effecting simultaneous sliding movements of said scale and said sliding part in the same direction along said longitudinal sliding paths; a seal secured within said housing and sealingly engaging the periphery of said sliding part while permitting sliding movement of said sliding part through said seal, said seal engaging said sliding part adjacent the other end thereof when said sliding part is disposed in said first end position; a force receiving member projecting from said housing and being connected to said sliding part at the other end thereof for effecting sliding movement thereof from outside the housing; and said sliding part in said first end position of its sliding path being substantially disposed within said housing, and in the course of sliding toward said second end position of its sliding path upon application of a force to said force receiving member being progressively projected through said seal from the confines of said housing.
Claim 3
Dependent Claim
27 words
A measuring device as set forth in claim 1, further comprising guide means in said housing for guiding said sliding part within said longitudinal sliding path thereof.
Claim 4
Dependent Claim
35 words
A measuring device as set forth in claim 2, wherein said sliding part is tubular in configuration and said guide means therefor is a guide bar upon which said tubular sliding part is movably disposed.
Claim 5
Dependent Claim
44 words
A measuring device as set forth in claim 1, further comprising guide means adjustably secured within said housing for guiding said means connecting said scale and said sliding part for movement along a longitudinal path parallel to the longitudinal sliding path of said scale.
Claim 6
Dependent Claim
26 words
A measuring device as set forth in claim 1, wherein said scale is constructed as a screen and further comprising a counter-screen for providing optical scanning.
Claim 7
Dependent Claim
38 words
A measuring device as set forth in claim 1, further comprising cylindrical guide elements secured to each end of said scale and a bore in said housing in which said cylindrical guide elements are slidably disposed without clearance.
Claim 8
Dependent Claim
18 words
A measuring device as set forth in claim 1, wherein said seal is formed by a lip seal.
