Abstract

Abstract The case-stand performs two functions; as a protective case in the fully closed position, and as a desk stand in the fully open position for hand-held calculators, computers, and data collectors; comprises a case bottom (1) which holds the instrument (17) securely by the insert holding feature (11) and a case top (2) which has a latch (7) feature that allows the case bottom (1) and case top (2) to securely latch together in the fully closed position. The case bottom (1) and case top (2) are hinged together with hinge (3) with two pins (4) which are pressed through case bottom (1) hole (13) into hinge (3) hole (15) in each of case to the proper depth and with two pins (4) which are pressed through case top (2) hole (14) into hinge (3) hole (15) in each side of case to the proper depth. Hinge (3) is located at the top edge of the case and instrument (17) allowing the case top (2) to swing approximately 360 degrees underneath the case bottom (1) interlocking together using the insert locking feature (8) of case top (2) and the cavity locking feature (9) of case bottom (1) to lock these two parts together in the fully open stand position so they cannot move passed each other when the user is keying the instrument (17). Case top (2) has an insert holding feature (10) which helps hold the case top (2) to the instrument (17) in the fully closed position. The bottom case (1) has a latch recess (12) to allow the user to place his finger or thumb under the case top (2) latch (7) feature to push upward to unlatch the case top (2) from the case bottom (1) whereby opening the case for use by placing the case in a desk stand position. The case top (2) has a non-skid foot (16) feature that is made of soft rubber, which serves to hold the desk stand to any smooth desk surface while the user is keying the instrument (17). The case top (2) has a nameplate (5) attached with epoxy (6) in the recess area for the nameplate. The case-stand will vary in size to fit each size hand-held calculator or hand-held computer, or hand-held data collector. These items are referred to as an instrument in my patent application.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 210 words
A combination case-stand for holding hand-held instruments, such as calculators, computers or data collectors, comprising: a rectangular case bottom, a rectangular case top and a hinge member made of hard, durable material of sufficient size to accommodate and encase such instruments, the case bottom and the case top each having a first end and a second end, a first set of hinge pins journalled in aligned hinge knuckles on a first end of the case bottom and a first edge of the hinge member for attaching the case bottom to the hinge member, and a second set of hinge pins journalled in aligned hinge knuckles on the first end of the case top and a second edge of the hinge member for attaching the case top to the hinge member, whereby the case top can be pivoted about the second set of hinge pins from the case bottom and then shifted over the first end of the case bottom in a direction to rotate the hinge member approximately one hundred and eighty degrees about the first set of hinge pins allowing the case top to be pivoted further about the second set of hinge pins to a position underneath the case bottom to form a support stand for the latter.
Claim 2
Dependent Claim 210 words
A combination case-stand for holding hand-held instruments, such as calculators, computers or data collectors, comprising: a rectangular case bottom, a rectangular case top and a hinge member made of hard, durable material of sufficient size to accommodate and encase such instruments, the case bottom and the case top each having a first end and a second end, a first set of hinge pins journalled in aligned hinge knuckles on a first end of the case bottom and a first edge of the hinge member for attaching the case bottom to the hinge member, and a second set of hinge pins journalled in aligned hinge knuckles on the first end of the case top and a second edge of the hinge member for attaching the case top to the hinge member, whereby the case top can be pivoted about the second set of hinge pins from the case bottom and then shifted over the first end of the case bottom in a direction to rotate the hinge member approximately one hundred and eighty degrees about the first set of hinge pins allowing the case top to be pivoted further about the second set of hinge pins to a position underneath the case bottom to form a support stand for the latter.
Claim 3
Dependent Claim 59 words
A combination case-stand according to claim 1, in which: the second end of the case top has a latch element engageable with a keeper on the second end of the case bottom, whereby downward on the case top causes the case top and the case bottom to latch together securely in the fully closed position to encase the instrument.
Claim 4
Dependent Claim 41 words
A combination case-stand according to claim 2, in which: the second end of the case bottom has a recess to allow a user to apply upward pressure on the latch element to cause the latter to unlatch and open the case.
Claim 5
Dependent Claim 34 words
A combination case-stand according to claim 1, in which: the case bottom has side walls provided with instrument holding means for holding the instrument securely while in use in a fully open stand position.
Claim 6
Dependent Claim 34 words
A combination case-stand according to claim 1, in which: the case top has side walls provided with instrument holding means to help hold the case top against the instrument in the fully closed position.
Claim 7
Dependent Claim 56 words
A combination case-stand according to claim 1, in which: a soft rubber non-skid surface material is on an outer surface of the case top, the non-skid material is effective when the case-stand is in the fully open stand position to restrain the case-stand against sliding movement when placed on a smooth desk surface when being used.
Claim 8
Dependent Claim 54 words
A combination case-stand according to claim 1, in which: an insert locking means on the second end of the case top that can be inserted into a cavity locking means in the second end of the case bottom to hold the case bottom and the case top together in the fully open stand position.
Claim 9
Dependent Claim 37 words
A combination case-stand according to claim 1, in which: in the fully closed position as in the fully open stand position the same area of space is taken up on the desk surface by the case stand.
