A refrigerating unit includes a cooling chamber, a storage compartment removably guided within the chamber as far as a closing position, and a disengagement device. The chamber has a parallel-guide disposed on its sides. The guide has a mating toothed configuration, two rollers rigidly coupled, lying opposite each other, and each having an external toothed configuration with a pitch circle diameter to be rollingly coupled to the mating toothed configuration. The guide has an end section reached by the rollers near the closing position. One of the mating toothed configuration and the rollers is positionally fixed. The disengagement device disengages the mating toothed configuration from the external toothed configuration of the rollers and is at the end section and has a disengagement length compensating for oblique positioning of the compartment in and counter to a movement direction arising from an offset of the rollers along the mating toothed configuration.

1. A refrigerating unit, comprising: a cooling chamber having two longitudinal sides; a storage compartment removably guided into and out of said cooling chamber in a movement direction, said storage compartment removably guided into said cooling chamber along said movement direction as far as a closing position; said cooling chamber having a parallel-guiding device disposed on said two longitudinal sides along said movement direction; said parallel-guiding device having: a mating toothed configuration; two rollers coupled approximately rigidly to each other, lying opposite each other at least substantially on a given axis, and each having an external toothed configuration with an identical pitch circle diameter to be rollingly coupled to said mating toothed configuration, one of said mating toothed configuration and said rollers positionally fixed with respect to said cooling chamber; and an end section reached by said rollers along said movement direction by said closing position of said storage compartment; and a disengagement device for disengaging at least part of said mating toothed configuration from said external toothed configuration of at least one of said two rollers, said disengagement device disposed at said end section and having a disengagement length sufficient to compensate for an oblique positioning of said storage compartment in and counter to said movement direction arising from an offset of said two rollers from one another along said mating toothed configuration. 2. The refrigerating unit according to claim 1, wherein said storage compartment is removably guided into and out of said cooling chamber as a drawer. 3. The refrigerating unit according to claim 1, wherein said disengagement device is disposed at said end section and has a disengagement length sufficient to compensate for an oblique positioning of said storage compartment in and counter to said movement direction arising from a tooth pitch offset of said two rollers from one another along said mating toothed configuration. 4. The refrigerating unit according to claim 1, wherein: said disengagement device is a tooth space in said mating toothed configuration; and said tooth space is disposed at a space section of said mating toothed configuration to be rolled over by said rollers at said end section. 5. The refrigerating unit according to claim 4, wherein: said parallel-guiding device has two parts each having said mating toothed configuration for a respective one of said two rollers; each of said mating toothed configurations has: teeth with at least one tooth height: said tooth space; and a feeding region for said rollers; said feeding region has teeth with an increasingly rising tooth height at least approximately continuously to a final tooth height; and said tooth space is adjoined by said feeding region. 6. The refrigerating unit according to claim 1, wherein: said parallel-guiding device has two parts each having said mating toothed configuration for a respective one of said two rollers; and each of said mating toothed configurations is disposed on a respective one of said longitudinal sides along said movement direction. 7. The refrigerating unit according to claim 5, wherein said feeding region is disposed downstream of said tooth space with respect to a removal direction of said storage compartment from said cooling chamber.
