Embodiment Construction

[0029] Figure 1a , 1b And 2 shows a tape measure housing 10 for a short tape measure, the housing containing two halves 12, 14 made of injection molded plastic material such as ABS. Elastomer pads 13, 15 are molded on each half. The gaskets 13, 15 have two inflatable cavities. The first is the cavities 16, 18 provided in the corners away from the mouth on the bottom edge of the housing, through which the measuring tape wound in the housing is drawn out. These cavities extend to the outside of the elastomer gasket so that they are visible during normal use of the housing. Cavities 16, 18 such as figure 2 The illustration extends to the junction between the two halves 12, 14 of the housing 10, but is parallel to the edges of the housing that join the front and back sides.

[0030] These cavities 16, 18 protect the vulnerable corners of the housing.

[0031] Set on two elastomer spacers ( figure 2 Only the other cavities 17, 19 in the gasket 15) are shown in the gasket located on...

Abstract

The invention provides a tape measure housing having resilient material located at its outer surface. The resilient material defines one or more gas-filled cavities, each of which is located on a line tangential to an outer wall of the housing between the outer wall of the housing and an outer wall of the resilient material. This provides improved shock protection.

Description

Technical field [0001] The invention relates to a housing for a tape measure and a tape measure containing the housing. Background technique [0002] A flexible short tape measure wound on a reel is known, which can be loosened from the reel for use and then retracted again after use for convenient storage. The mandrel is usually formed on or connected to a housing containing the wound tape measure reel and the return spring. The housing is usually formed with two parts, one part carries the mandrel on which the reel is mounted, and the second part cooperates with the first part to completely or partially enclose the tape measure. The tape measure is wound on the reel. In any case, the entire housing has an opening through which the tape measure can be extended or retracted. [0003] In addition, a flexible long tape measure is known, which is connected to a reel in a housing through a guide. The reel is usually formed integrally with a winding center and a winding handle for w...
