SUPPORT FOR CARRYING CASE
Abstract
A support for a carrying case for apparatus to be carried by a
person supports the case on a belt, or the like, and permits the
same to pivot with respect to the belt and to be easily and quickly
connected thereto and detached therefrom. This support can be used
for apparatus such as a personal radio paging receiver, or any
other device which is to be carried by a person. The support
includes a receptacle secured to the belt having a nonsymmetrical
opening therein. The carrying case has a plate thereon with a
button projecting therefrom having the same shape as the opening in
the receptacle. The button can be inserted into the opening when
the carrying case is in a position it will not assume during normal
use, and will be retained when pivoted to other positions which it
may assume during use.

Description
BACKGROUND OF THE INVENTION
It is common practice to carry personal devices on a belt, so that
the device is always present when needed. Carrying cases for
various different types of apparatus have been provided, which are
supported on belts worn by the user. There has been a substantial
demand for personal radio receivers so that the user can receive a
message at any time, thus being in continuous communication with
some other person. For example, repair men frequently carry radio
paging receivers to receive instructions from their office as to
further calls to be made.
It is desired that the carrying case for the radio receiver or
other device be easily and quickly detachable from the belt and
that it can be worn comfortably thereon. Paging receivers are
commonly constructed in rectangular configuration and may have a
length of 5 inches or more. It is customary to carry the pager on a
belt in vertical position, as the speaker of the pager is commonly
mounted at the top and the sound therefrom will thus be easily
heard. However, when an elongated device is so supported on a belt,
a problem is presented when the user attempts to sit down as the
lower end of the device may engage the seat. For example, radio
receivers are frequently carried by police officers who must at
different times be standing, walking or riding in a car. It is,
therefore, desired that the carrying case for the paging receiver
or other device be arranged to be movable in position for the
comfort of the user.
SUMMARY OF THE INVENTION
It is an object of this invention to provide an improved support
for a carrying case for apparatus to be carried on the person.
Another object of the invention is to provide an improved device
for connecting a carrying case to a belt, which provides quick and
easy attachment and detachment.
A further object of the invention is to provide a device for
securing a carrying case to a belt which permits pivotal movement
of the carrying case and quick detachment thereof, while preventing
unintentional detachment.
A still further object of the invention is to provide a device for
pivotal mounting of a carrying case to a belt which can be
constructed of simple and inexpensive plastic parts.
The connecting structure of the invention supports a carrying case
on the belt worn by a person. The carrying case may be used for a
personal radio paging receiver or any other device to be
continuously available to the person. THe device includes a
receptacle to be secured to the belt, either by direct detachment
thereto or by use of a holder about the belt, which receptacle has
an opening therein of nonsymmetrical configuration, such as
D-shaped. The carrying case has a plate secured thereto with a
button extending therefrom which has the same configuration as the
opening in the receptacle (D-shaped). The opening in the receptacle
is positioned so that the button can be inserted therethrough when
the carrying case is in a position not encountered during normal
use, such as upside down. After the button is inserted, the case
can be pivoted and the nonsymmetrical shape of the opening will
prevent withdrawal of the button to prevent unintentional removal
of the case from the belt. The case can be pivoted through a
relatively wide range of angles as may be caused by motion of the
user, without being disconnected from the belt. This has the
advantage that a relatively long case can be pivoted when the
person weraing the same sits down, so that the person can be more
comfortable. The connecting parts can be molded of plastic to
provide an inexpensive construction.

DESCRIPTION OF THE STRUCTURE SHOWN IN THE DRAWINGS
Referring now to the drawing, FIG. 1 shows a carrying case 10 which
may be used for a radio paging receiver or other device which is
secured to a belt 12 by a holder 14. The structure for connecting
the carrying case to the belt is shown more clearly in FIGS. 2 and
3. It will be seen that the holder 14 includes a loop 15 around the
belt 12, with the bottom ends of the sides thereof fastened
together with snaps 16. Alternately a continuous loop can be used
through which the belt is threaded when it is put on. A retainer
plate 18 on the holder has an opening 19 therein which is of
D-shape. The plate 18 is secured to a supportiong plate 20, which
may be of leather or other suitable material, and which is secured
to the loop 15 about the belt. The supporting plate 20 has an
opening 22 therein back of the opening 19 in the retainer 18, and
of a larger diameter, forming a recess behind the retainer plate
18.
Connected to the carrying case 10 is a plate 24 on which a button
26 is secured. The button 26 is also D-shaped and is of a size that
will pass through the opening 19 in the retainer plate 18. The
button 26 is secured to the plate 24 by a post or stud 28 of
smaller size than the button, and having a flat surface aligned
with the flat side of the D of the button 26. The button 26,
therefore, forms a flange with a recess therebehind.
It will be apparent from FIG. 2 that when the carrying case is in
the position shown, the button can be inserted through the opening
19 in the retainer plate 18 into the recess in supportiong plate
20, and then pivoted to the position shown in FIGS. 1 and 3. The
center of gravity of the case 10 and the device therein is below
the pivot, so that the case will be held in this position. In this
position the flange formed by button 26 is held by the flat side of
the opening in the plate 19, so that the carrying case cannot be
detached. However, the carrying case can be easily detached by
rotating the same to the position shown in FIG. 2.
It will be obvious that the carrying case 10 when supported on the
belt 12 by the holder 14 can pivot to various positions as the
person wearing the belt moves. FIG. 4 shows the carrying case 10
pivoted so that it rests at an acute angle with respect to the belt
12, when the person wearing the same is in a seated position, as in
an automobile. The carrying case is retained during such movement,
and is not detached until it is pivoted almost 180.degree., as
shown by FIG. 2.
Instead of using a holder 14 which has a loop 15 surrounding the
belt, the holder can be attached directly to the belt 12. Also, the
retainer plate 18 and the supporting plate 20 can be provided as a
single integral member. This is shown in FIGS. 5 and 6 wherein the
combined receptacle member 30 can be molded of plastic material.
This member has holes 32 in the corners thereof which can be used
to directly fasten the same to a belt 12, as by rivets 34 (FIG. 6).
Alternately the retainer member 30 can be fastened to a loop which
surrounds the belt, as illustrated in FIGS. 1, 2 and 3. As shown in
FIGS. 5 and 6, the member 30 has a recess with a first part back of
the flat side of the D-shaped opening 19 and a second part back of
the opposite curved side of the opening 19.
FIGS. 7 and 8 show an alternate construction of the button and
supporting plate which can also be molded of plastic material. The
button 36, mounting stud 37 and plate 38 are molded as a single
member. The mounting plate 38 has opening 39 therein for receiving
rivets 40, or the like, for securing the same to the carrying case
10 (FIG. 8). Alternately, the plate 38 (and similarly the plate 24
in FIGS. 2 and 3) can be directly secured to the device to be
carried, such as the housing of a paging receiver. By connecting
the plastic retainer of FIGS. 5 and 6 directly to a belt or other
supporting member, and by directly connecting the button member of
FIGS. 7 and 8 directly to the device to be carried, a very simple
and inexpensive connecting structure is provided.
The supporting structure described has been found to be highly
satisfactory in tests which have been made. The quick attachment
and detachment provided is very desirable, and the pivoting action
which is permitted is advantageous.
